Specified demand display device

FIELD OF THE INVENTION

2[0001] The present invention relates to a display device specified demand.

BACKGROUND OF THE INVENTION

4[0002] The contract for the use of electricity between electricity companies and consumers of electricity, payments for electricity are divided on the basic tariff, which are parts of fixed rate and variable rate part, which are determined on the basis of energy consumption. The total sum of the above two parts is calculated as the cost of electricity, and rests on the shoulders of consumers. The main way to establish the basic tariff, which are parts of a fixed rate, as mentioned above is the following method. Namely, electric power companies is summed for a long time consumed for power consumers more predetermined time slots (e.g., 30 minutes each). The electrical energy produced by the process of the above summation is measured as the value of the demand for the respective time slots. The amount of monetary value that corresponds to a predetermined reference value corresponding to the largest value of the demand (i.e., the maximum value of demand), among the measured demand values ​​as indicated above for the previous predetermined period (for example, one year), is used as the base rate for the subsequent deadline.

5[0003] The above system will be explained in detail with reference to FIG. 1. FIG. 1 is a graph showing the change in the monthly value of demand in electric power consumers. The term "monthly value demand" refers to the maximum value of demand during the relevant month. The vertical axis in FIG. 1 represents the value of the electricity demand. The above-mentioned predetermined period is set to one year from 1 July each year on the last day of June of the following year. It is expected that the monthly base rate for the year from July 2010 to June 2011 is 2800 yen.

6[0004] As shown in FIG. 1, resulting in a sharp increase in the use of electricity in June 2011, the rate of 3,200 yen, which was the base rate for the coming year, has exceeded the relevant consumer of electricity. In this case, the rate of 3200 yen was used as the base rate since July. That is, the base rate increased by 400 yen, which is approximately 14% increase compared to the previous rate. No matter how strong underlying demand fell, the rate of 3200 yen remained the basic tariff. Furthermore, in the case of large power consumers, if the electricity demand of electric power values ​​exceed the values ​​defined when the contract, then in such consumers can be fined, for example, fines corresponding to such elevations.

7[0005] As described above, in the case where the value of the demand grows, even temporarily, then even if the value of the demand falls, the basic rate is set at a high level. That is why the measures on the electricity consumption (for example, energy-saving steps), which can reduce the value of demand, are medium and long term economic interests of individual consumers. That is why the overall demand for technology to display a degree of change of values ​​based on the ratio of demand to a reference value in determining base tariffs power companies for a specific time slot (hereinafter, sometimes just a segment), and also allows you to provide an easy understanding of such changes.

8[0006] In this connection, Patent Reference 1 discloses an example of technology that is used to display a given demand device. This device sets a target value for the calculation of basic electric rates as the upper limit target value (for example, set the value of demand), and shows the relationship between these specified values ​​and demand values ​​demand at predetermined times using a disc-shaped outer edge of the clock.

10SUMMARY OF THE iNVENTION

11Problems to be Solved by the Invention

12[0008] In recent years, it has become known technology that uses radio waves of the reference time as a way to synchronize the time with a watch. That is, for the time display unit is adapted for receiving a standard time radio wave at a predetermined timing. Thus, it is possible to indicate the exact time without the need to expend effort on user configuration time. Many of the devices for indicating time, including widespread hours using a method for receiving radio wave reference time as a means of obtaining information on the time because of its high degree of convenience.

13[0009] In the measurement of the demand values ​​at a specified time, power companies use electrical signals transmitted through electrical cables laid by these companies, as described in detail below, using radio waves instead of the standard time as described above.

14[0010] FIG. 2 shows a diagram of the method of measurement values ​​demand power companies and electricity consumers. As shown in FIG. 2, power companies get information on time through the "power meter" (0201), using pulses of alternating current AC, supplied by these companies. "The display device of predetermined demand" (0202) used in the conventional technology adopts a "radio wave standard time" (0203), measures the value of the demand at a predetermined timing, and outputs information about them in the same manner as in the collection time information that allows the device to indicate the time. That is, the methods of measuring the value of demand and time points are displayed using such methods, for different power companies and electricity consumers.

15[0011] As described above, there is a discrepancy between the values ​​of the electricity demand of consumers, which are measured and electricity companies are accepted at a given time and the values ​​of the demand, to identify the relevant consumers of electricity with the help of the display device specified in demand due to the difference in information. As a result of the above-mentioned differences, even if the value of the actual demand, for example, exceeds a predetermined value demand of electricity consumers may mistakenly consider that the value of demand does not exceed the specified values ​​demand. As a result, a situation may arise when the electricity consumers are required to pay higher base rates for a long time. With respect to the device for indicating the predetermined demand based on the time information, which differs from the information used by electric utilities, as in the case of the conventional technology described above, a situation may arise when the economic interests of electricity consumers who trust the information displayed by the device predetermined display demand to be damaged, and therefore there is a need to avoid such a situation.

16[0012] Due to the regional and local restrictions on the state of the environment to receive standard time radio waves there is a constant error in time synchronization, or first radio wave reception of the reference time has been difficult. In particular, the time display device installed in mountain areas and underground at large distances from a reference radio wave transmitting places time placed in an environment where radio wave reception of the reference time is difficult. For this reason, it is impossible to receive radio waves for correcting the time base at regular intervals of time. Therefore, in the above mentioned areas is difficult to establish the relationship between the values ​​of demand and given values ​​based on supply accurate time information.

17Means for solving the problem

18[0013] In order to solve all the various above-mentioned problems, the present invention provides an apparatus displaying a given demand, comprising a combined scale with the time and power consumption indication unit time to indicate time by using a combination of the scale unit of collecting information on the electric power consumption for data electric power consumed up to the current time in the time slot for a given demand, including the current time, a block indicating an end to indicate the relationship between energy consumption within a given time segment recorded by the information acquisition unit of the power consumption and the required setpoint assigned to that time slot, the unit receiving an AC signal for receiving AC signals, using pulses of the AC line power unit generating time information for generating time information based on the received AC signals, a transmitting unit for transmitting the housing generated time information via radio waves, a receiving unit in the housing for receiving timing information using radio waves, and the display control unit to control the time unit of time display unit using the received time information.

19The beneficial effect of the invention,

20[0014] According to the present invention having the basic configuration described above, it enables consumers of electricity in different environments to determine the value of demand, which did not differ from those specified power companies, which allows such users to determine the relationship between these values ​​demand and given values ​​of demand, and contribute to the timely adoption of energy efficiency measures.

The present invention is not limited to the above exemplary embodiments and can be embodied in various forms within its scope (the same applies to all specifications and drawings).

40The first example of the invention

41The concept of the first embodiment

42[0017] FIG. 3 shows a diagram of a display device according to a first predetermined demand and fourth embodiments of the invention. As shown in this diagram, FIG. 3, when receiving electricity through a power line, a display device given the demand for the first embodiment of the invention simultaneously receives information on electricity consumption for the identification of the basic payment, as well as instant information used to display the time, became the starting point of the range to a given value of a given demand which includes the current time. display the specified demand device shows the ratio between the maximum demand (ie, the value of demand) and the set point of demand, and this ratio is related to time. When electricity consumers are looking at the display device with the configuration described above, they can accurately understand the extent to which the actual value of demand reaches a predetermined value (in fact, such a value is not different from that obtained by the electric power company). Such an understanding of the set values ​​of demand can be achieved in all the places where consumers are able to receive electricity. Such consumers can immediately reduce electricity consumption through energy-saving measures, building on the level of the desired result.

43Functional configuration of first embodiment

44[0018] FIG. 4 shows an example functional block diagram of a display device according to a first predetermined demand example embodiment. As shown in FIG. 4, "a display device specified demand" (0400) according to a first embodiment of the invention includes "a combined scale" (0401), an 'acquisition of the electric energy consumption information' (0402), an 'indication achieving "(0403), a' receiving unit AC signal "(0404)," unit generating time information '(0405),' transmission unit '(0406),' receiving unit '(0407), the "time display unit control unit' (0408), and" display unit time "(0409). FIG. 4 shows an arrangement whereby the time display unit fulfills its function directly for the combined scale. Meanwhile, FIG. 5 is a diagram showing another example functional block diagram of a display device of a given demand in the first embodiment. As shown in FIG. 5, based on the premise that "the time display unit '(0509) is able to perform its function to" display unit achieving "(0503), and that such a function has been performed, a display unit of achievement may be adapted to perform its function for "combined scale" (0501). This configuration allows viewing perform control so as to provide a clear display of the relation between the consumed electric power demand and setpoints at predetermined time segments.

45[0019] "Combined scale" is a scale for indicating the time and consumed energy, as described below. That is, it is possible to display the time and energy simultaneously with a single scale. In many cases, the location of the scale can be combined outer surface region for displaying chronograph time, as shown in FIG. 3. However, this location is not limited to that described above, provided that the provided display information about the time and electric energy. Combined scale may display values ​​based on a set of 60 characters that represent 60 minutes, as is the case with ordinary scales clock used for time display. As an alternative example, it is possible to set the number of digits a multiple of 60 (e.g., 120) or as a divider 60 (for example, 12).

46[0020] "time display unit" has a function to display the time with a combination of the scale. The outer label on the combined scale used to indicate power relative to the target demand during a predetermined time period. For example, the time segment including the current time, set the duration of 30 minutes from the beginning of an hour to 30 minutes after the start. Then another set of identical duration time segment at the end of the first time segment and continuing until the next hour. In this case, the external marks corresponding internal marks denote setpoint demand. For each time segment of the aforementioned external markers are located on the corresponding half scale. Furthermore, the time display unit can also have the function of indicating the current time via a combined scale.

47[0021] Displaying the beginning or end of the time slice for the given setpoint demand may be combined with the display of the current time, when the current time is the start time or the end of this time segment. An example of a specific display method is a method in which the portion shown on the combined scale, illuminated by illumination device such as light bulbs or LEDs. An example of a method of lighting is a method in which maintains a constant light intensity of the beam to the end of the time slot or a method in which a beam of light flashes or blinks continuously for a predetermined time. This method of illumination is not limited to the above methods provided that the time slot for the setpoint demand comprising the current time can be visually recognized.

48[0022] "AC signal receiving unit" has a function of receiving the AC signal, which uses alternating current pulses in the power line. The term "power alternating current power line" refers to a commercial power source, established power companies for electricity consumers. Generally speaking, large fluctuations in the balance of supply and demand of electricity can lead to changes in the voltage of the commercial power source provided by the power companies. If not supported by the appropriate voltage, it can lead to improper functioning of electric power consumers or loss of electrical power transmission. Accordingly, to avoid unfavorable factors that accompany fluctuations in demand and supply of electricity, as described above, the power companies are implementing control measures so as to minimize the deviation of voltage and frequency of the commercial power source. Thus, the above-mentioned "food for alternating current transmission line" is a stable form of alternating current pulses through the above-mentioned control, the embedded power companies. As described above, a configuration which is obtained using alternating current having a stable pulse shape allows stable timing time and almost unerring way using such AC signals.

49[0023] "unit generating time information" has a function of generating time information based on the received AC signals. The expression "generating information based on the received AC signals time" in particular refers to a process of alternating current signals at certain cycles and cycles in synchronization with timing of time. For example, the frequency of commercial power used around the world, is now either 50 Hz or 60 Hz. Thus, the time information is generated so that it was synchronized with the frequency of the above cycles. That is, if the above frequency of commercial power is 50 Hz, then made 50 cycles per second. If the aforementioned commercial power frequency is 60 Hz, then made 60 cycles per second. The time information is generated by timing the time under the above conditions.

50[0024] As indicated above, the power supply frequency varies between countries and regions within the same country. For example, Japan is used and 50 Hz, and 60 Hz. In European countries using 50 Hz. In the United States use 60 Hz. Therefore, the configuration, according to which the time information is generated on the basis of numerous different AC signal can be set to block the generation time information. This configuration allows for accurate information about the time, even in any environment anywhere in the world, in which the state of a reference time radio wave reception is unstable.

51[0025] "The transmitting unit" has a function to transmit the generated time information using radio waves within the housing. The expression "within the housing" means that the transmitter unit is located within the housing of a display device specified demand. Long-time clock synchronization for the transmission of the time information is not preferred. Preferably, the short-period clock time synchronization, for example, every second. For example, five seconds is acceptable. Since this time the control unit allows the time display unit, described below, to perform control based on accurate information, a time can be set arbitrarily.

52[0026] "receiving unit" has the function of obtaining information about the time transmitted via radio waves inside the cabinet. The expression "getting inside the case ..." refers specifically to a situation where the above-mentioned time information transmitted via radio waves inside the housing, is received within the same housing of the display device specified demand. Configuration, whereby the transmitting unit and a receiving unit mounted in relative proximity to each other, does not require a high level of field strength for the radio waves. This configuration does not require compliance with legal regulations, etc., according to which the required permits, etc. transmission of radio waves with a certain field strength or higher.

53[0027] In addition to the above effects, a receiving unit and a transmitting unit mounted as separate component parts. Thus, the existing mechanism can be changed and so electric wave clock. Conventional technology. That is, the conventional electric wave clocks include a receiving unit for receiving radio wave reference time from an external source. The transmitting unit, a generating time information, and the apparatus receiving an AC signal can be set to the aforementioned electric wave clock mechanism. This configuration allows the display to configure a given demand apparatus according to the first embodiment of the invention. In this case, a receiving unit configured to receive the time information transmitted from the radio wave transmitting unit in place of the reference time. In this connection, a transmitting unit and a receiving unit adapted to exist in close proximity to each other in one body a predetermined display device demand. Typically, information from the transmitting unit to the receiving unit is transmitted through a relatively long distance. With the device according to the present invention, said information can be obtained instead of the reference time of radio waves that are prone to a certain extent in the free space attenuation. In any case, this configuration makes it possible to solve the questions posed by the corresponding conventional technology while maintaining and using such technology for an electric wave clock.

54[0028] "Control unit indicating unit time" is the time display control function unit using the received time information. The expression "control time display unit using the received time information" refers specifically to a situation where specific information about the time handled as such, the time display device. Use the example of the interval for the demand above the setpoint demand. In this case, when the received information is information indicating the time to the onset time of 10:30 can perform control so that the information can be visually recognized by blinking the appropriate combination section, etc. scale. In addition, the control may be included feature that It allows you to display the current time using the minute hand, etc. hours on a combined scale and outside the predetermined display device demand. As described above, the configuration of which is shown using the same time used by the utility company, to avoid a situation where there is a difference in the definition of electricity consumed and by the electric power between the power consumers. Furthermore, the above configuration allows to visually recognize the current time and the degree of achievement generalized manner, by using only said predetermined demand display device of the first embodiment, or based on a combination of such devices and watches in any environment in which electric power can be used.

55[0029] "Unit collect energy consumption data" has a function of acquiring data concerning electricity consumed before the current time in this range for a given setpoint demand, including the current time.

56The term "desired setpoint" refers to the value of electricity which is a predetermined upper limit consumption for a predetermined time interval. A specific method for determining the predetermined upper limit is a predetermined setting value selected from the values ​​of consumed electricity. This value is taken as a reference value for calculating the base power companies payments as described above. For example, the total power consumption for 30 minutes does not exceed 60 kW. If it is set as a target, the demand setpoint may be 60 kW.

57[0030] Possible configurations whereby power consumption information is obtained via a wired or wireless communication link from the power consumption metering device mounted to the power line. Acceptable is the presence of one main transmission line for one building. If there are power lines to all parts of the electrical equipment for a room or for all rooms of a building, it is possible categorization given electrical receiving information on consumed electricity. Thus, it is possible to control the power consumption in detail. For example, in the case where the power obtained from the power lines connected to the output unit, each individual unit of electrical equipment may be subject to controls. In this case, it is convenient to allocate power meters for all the points in order to use the data form to the electric networks (PLC - Power Line Communication), and receive information on the consumed electric power for all the electrical equipment. Different configurations, which produce information on the consumed electric power, allow interest to classify the electrical energy consumption. Thus, it is possible to set setpoints demand is based on building, office building, or a unit of electrical equipment and the degree of achievement of the set values ​​demand. In this case, the amount of electricity consumed, the scale combined on purpose, can be determined for each building or each item of electrical equipment. For example, you can specify the premises in which we have the power consumption and / or equipment that consumes electricity, using color, sound or display a sign function.

58[0031] The term "electric power consumed up to the current time interval for a given setpoint demand, including the current time" refers to the power consumption, characterized by the following example. The time now is 10:23. The time interval comprising the current time, set the duration of 30 minutes from the beginning of an hour to 30 minutes after the start. Then another set of identical duration interval starting from the end of the first interval, and continuing until the next hour. In this case, the external marks corresponding internal marks indicate demand setpoint. For each of the above intervals, external markers will be placed on the corresponding half scale. The above refers to the consumption of electric power for 23 minutes from 10:00 as a start time interval corresponding to the present time.

59[0032] Furthermore, to solve the problems with the conventional technologies described above, the aforementioned given interval for a given setpoint demand must be the same (or lower) the duration and start at the same time as the time interval used as the basis of charges by appropriate calculations of payments for electricity respective power companies. And such time interval must also satisfy the condition that at least some part of it must be superimposed on the time interval used corresponding electric company as a basis for calculation and, at least as long as the period with a value of time duration is a common divisor value the time duration of the above time interval. That is, when electrical consumers are making energy-saving actions, so that the consumption of electricity does not exceed the value given demand, the demand will decrease values, serve as the basis for the calculation of the basic payment, selected from the payments for electricity. As a result, in the long term it will be possible to reduce the charges for electricity. The interval for a given setpoint demand currently used among electric power companies in Japan, is 30 minutes. Thus, you can set the interval for the set point value of 30 minutes, demand or set above the range for a given value of a given demand value 15 minutes to formulate a more detailed plans for energy-saving measures. However, the above defined intervals were electricity consumers. Thus, it can be assumed that they can change the length of the aforementioned time intervals of intervals in the future. Thus, a given value interval for the demand is not limited to 30 minutes, acceptable intervals may be 15 minutes or 60 minutes. The preferred configuration which can be set to different values.

60[0033] "The display unit achieving the goal" has the function of indicating the relationship between the consumption of electricity within a given interval registered by the information acquisition unit of electricity consumption and demand for a given value set for this interval. It can be used in different ways to indicate the relationship between the consumption of electricity in a given interval registered by the information acquisition unit of electricity consumption, and the target demand value set for this interval. For example, it examines predetermined average power consumption, which represents the rate of power consumption in power consumption corresponding to a predetermined value in the range of demand for this demand setpoint and specify the power consumption at the appropriate times. You can specify the percentage of the electricity consumption, which has been consumed to the current time from the target power consumption within this range for a given demand visually recognizable manner using the relative location of the minute hand to the light emitting element or elements. That is, a method indicating percent power actually consumed so far predetermined time relative to the power consumption of the combined ranking scale using light emitting elements such as LEDs or electric light bulbs, with respect to the location of the minute hand.

61[0034] FIG. 6 is a diagram showing an example of a specific method for computing power consumption during the period from the start time for the interval of the predetermined value until the end of the demand interval. FIG. 6, the value of "a" represents demand setpoint and the value "A" denotes the power consumed in a predetermined time indicated by the minute hand. The value of "B" denotes the amount of electric power actually consumed before the above time. Special function display unit achieving is to indicate the percentage of B to A as shown in FIG. 6 using the location of the minute hand with respect to the light emitting element or combination of elements of the scale. In particular, FIG. 6 The value exceeds the value of A. Thus, using fluorescent lighting, you can specify the position of the location of the minute hand.

62[0035] FIG. 7 is a diagram showing an example of the display unit display the goal, using marks in the form of rods. In the same manner as previously used in the example, the given value interval for a predetermined duration demand set to 30 minutes from the beginning of an hour to 30 minutes after the start. Then another set of identical length interval, starting from the end of the first interval and continues until the beginning of the next hour. FIG. 7 is a diagram showing an example of display at time 10:23. FIG. 7 "external mark in the position corresponding to the inside of the mark indicating the beginning of each hour" (0703) on the combined scale is a starting point. Rod shaped markers arranged sequentially, beginning from the starting point, as described above, to the "outer mark in a position corresponding to the inner mark indicating 18 minutes of the next hour" (i.e., the position corresponding to 60% of the range for the setpoint demand) (0702) . The aforementioned display allows you to visually determine that the electric energy was spent, equivalent to 60% of the set value of demand, set at the current time.

63[0036] For achieving the display unit, such a configuration is acceptable that the function block has a constant determining whether the value of power consumption exceeds the current time obtained by the information acquisition unit of the power consumption, setpoint demand. The expression "continuous determination" refers to the situation where the determination takes place in a shorter period of time than the corresponding time interval. For example, in the case where the duration time period is 30 minutes, determination takes place on a 30-second or one-minute basis. In the case where the duration time period of 2 hours determination occurs at 5-minute basis. The display unit achieving determines "whether the value of electricity consumption at the end of the interval exceeds the setpoint demand." Furthermore, this block is acceptable for such a configuration that enables to determine the degree of excess or rejection. For example, one can calculate the percentage exceeds whether or behind the above calculated power consumption from the set value during the respective demand time interval. (This will be explained in detail in the fifth embodiment).

64[0037] An example method for indicating the above ratio is described below. In the case where the power consumption at a certain time exceeds the predetermined value while the demand, a warning may be issued by symbols, colors, pictures and so on. The display device. As an alternative example, an audible alarm can be issued. On the other hand, in the case where the power consumption does not exceed the predetermined demand value can be prevented to reject using the same variety of means, as described above. Furthermore, it is also possible to install a plurality of phases so as to be set depending on the degree of difference between the aforementioned electric energy consumption and demand a predetermined value, which is expressed subsequent indication representing various types of information. For example, the following display methods using different colors. If the difference is positive (i.e., if the power consumption exceeds a predetermined value demand), the method can display red. In the case where there is no difference, the method can display green. And in the case where the difference is negative (i.e., if the electric power consumption is less than a predetermined value demand), a method is possible in blue display.

65[0038] It is possible to pre-store information about a given value of demand used to gather information about the unit electricity consumption and unit indication of achievement in the internal memory unit. It is also possible to receive the above information from external devices via communication lines, for example, via a wired or wireless link or PLC. In addition, you can also take workers input data via the input device and operative to receive the above information through the storage unit, for example, USB memory. It is assumed that the power consumption value accurately corresponding to a given demand, takes place during the interval of demand for a given value. In the case where the average power consumption takes place during a time interval, the ratio between the amount of electricity consumed to the current time and the electric power actually consumed up to the current time (i.e., the value obtained by the information acquisition unit of the electric power consumption) , corresponds to the "relationship between the consumption of electricity within a given interval, registered through the collection of information on energy consumption unit, and the set point demand set to such an interval of demand."

66[0039] Specialized configuration of display devices a given demand

67FIG. 8 is a diagram showing an example of a hardware configuration of functional blocks of a display device according to a first predetermined demand example embodiment. Operations for hardware configuration blocks are explained below with reference to FIG. 8.

68[0040] As shown in FIG. 8, display a predetermined supply device comprises "a central processing unit (CPU)" (0801), "a memory unit (storage means)" (0802), "random access memory (RAM)" (0803) "input interface," (0804), and "output interface" (0805). The input interface receives signals related to the power consumption of the "power meter" (0806), which determines the amount of electricity flowing through the "power lines" (0811). Furthermore, the input interface also receives the time information generated after passing through the "AC signal reception '(0807) and" unit generating time information' (0808) using the 'transmission unit' (0809) and "receiving unit" (0810). Further, the output interface transmits the signals for display "information display time" (graphic display is omitted) on a "combined scale" (0812). Furthermore, in the memory are the various programs the purpose of which will be explained below. CPU first deploys the program in RAM and then executes them. Elements of the above configuration are interconnected 'system bus' (0813) as the transmission element, the reception and processing of information.

Initially, it is determined whether a source is information used for generating the time information through the step of generating the time information, signals or radio frequency alternating current reference time (step 1201). In the case where it is determined that the source information used for generating the time information through the step of generating the time information are AC signals, the processing proceeds to step 1202.

On the basis of the processing result by comparing the phase indicates the degree of achievement of targets for the combined scale (S1215: step to achieve display purposes).

112[0066] After the presentation time phase and phase indicating an end, via step 1216 determines subsequent processing must be carried out. In the case where it is determined that the subsequent processing must be carried out, the processing is performed after step 1201 and step 1209.

118[0069] Functional configuration of a fourth example of the invention

119FIG. 13 is a diagram showing an example functional block diagram of a display device to supply a predetermined fourth embodiment of the invention. As shown in FIG. 13, (1310) of the fourth embodiment of "display specified demand unit" of the invention includes a "combined scale" (1311), an 'acquisition of power consumption information "(1312), an' indication of achievement" (1313), "transmission unit" (1314), "receiving unit" (1315), "time display unit control unit '(1316) and" display unit of time "(1317). A "power meter" (1300) for the calculation of payments for electricity contains "AC signal reception" (1301) and "generation unit of the time information" (1302). Explanation given by the display device demand that is not included in the explanation given demand display device of FIG. 4 first embodiment and the like, are given hereinafter with a focus on wattmeter comprising a unit receiving an AC signal generation unit and the time information.

120[0070] In the display device according to the demand for a predetermined fourth embodiment of the invention, a power meter for calculating charges for electricity generation unit includes the time information. The term "power meter for calculating payments for energy" refers to the watt-hour meter for measuring electricity by adding and metering of electricity supplied to every home, office, and facility. Based on the measurement of electricity using the watt-hour meter, electric companies calculate the amount of payments for electricity, which will be collected from each house, etc. That is, viewed watt-hour meter can be a device in which electricity is added to the summation function "wattmeter" (0806) shown for example in FIG. 8. As explained above, the part corresponding to base rates among electricity rates set by electricity companies, determined on the basis of the value of demand during a given period. Electricity companies are measured above a specified period, as well as the value of demand during this period using a power meter. Therefore, by the wattmeter function is required to keep generating the time information for synchronization of the aforementioned predetermined period. Using this feature information generation as a function of time in a predetermined display demand fourth example of the apparatus of the invention allows to omit the function of generating the time information in the display device designs within a given demand housing. Thus, it can provide users a predetermined display device of low demand.

121[0071] It is possible to transmit the time information generated by a power meter on the display device is given in demand through the power lines which connect the power meter to the display device specified demand. This transmit time information is forwarded from the transmitting unit to the receiving unit.

122[0072] Specialized configuration of display devices a given demand

Thus, it becomes possible to provide consumers with electricity demand predetermined display device that performs demand management at the time synchronization is performed electric power companies at a low price.

128[0075] The fifth example of the invention

129The concept of the fifth embodiment of the invention,

130demand predetermined display device according to a fifth embodiment of the invention is the same as that described generally in any of the first to fourth embodiments. The display device of predetermined demand according to a third embodiment of the invention is characterized in that the display unit achieving receives information on the estimated consumption of electricity as the electricity consumed in the range for a given demand and has means for displaying the difference on which appears the difference between the estimated power consumption and a given combined demand value scale. The above configuration makes it possible specifically and instantly understand the length of the period during which the ongoing energy-saving measures to achieve the goal, and the need or not energy efficiency measures.

131[0076] The functional configuration of the fifth example of the invention

132FIG. 14 is a diagram showing an example functional block diagram of a display device according to a fifth predetermined demand example embodiment. As shown in FIG. 14, "display a predetermined demand unit '(1400), according to the fifth embodiment of the invention includes" a combined scale "(1401), an' acquisition of the electric energy consumption information '(1402), an' indication achieving" (1403), an ' AC signal reception '(1404), "unit generating time information' (1405), 'transmission unit' (1406), 'receiving unit' (1407), the" time display unit control unit '(1408), and "block time display "(1409). The display unit includes an end "display means the difference" (1410). Explanation given by the display device demand that is not included in the explanation given demand display device of FIG. 4 first embodiment and the like, are given hereinafter with a focus on display means difference.

133[0077] "display means the difference" has the function of obtaining information about the projected energy consumption as the energy consumed in the range for a given demand, and a reflection of the difference between the projected electricity consumption and demand for a given value of the combined scale. The term "predicted power consumption" specifically refers to the estimated energy consumption from the start to the end of the interval for the demand setpoint to which the current time. As an example of the above prediction method, tabulating the power consumed to the current time using the information on the consumed electric energy from the beginning of the interval to a predetermined value demand to the current time, and use the resulting value as the electric power consumed when the power consumption It occurs with the same speed as the foregoing power consumption is summed with the power consumption.

134[0078] Referring again to FIG. 6 which is a diagram showing a concrete method of calculating the predicted power consumption to the end time in the time interval. As shown in FIG. 6, and can calculate a linear function MARSHALL predict power consumption and at the end of a respective slot. That is, based on the power consumption in the current time, power consumption β, to projected end time a predetermined time interval is calculated, and the comparison operation is used to specify the relation to demand value α. FIG. 7, which has already been used for explanation, an example of the display unit by the display device achieving the fifth embodiment of the invention. In the case where the total electricity consumption in the period from 10:00 to 10:18 is 18 kWh, provided that power consumption continues at the same rate to 10:30, the total energy consumption of 30 kWh for 30 minutes (including the remaining 12 minutes). The above configuration makes it possible for consumers of electricity forecasting whether they can reach the goal for the actions on energy consumption, at some future time, which is the end time of the time interval.

135[0079] The processing for calculating predicted energy consumption is performed at predetermined time intervals (for example, with 15-second intervals, or one minute intervals), and prediction data is updated in each case. The aforementioned specified time intervals do not need to be any specific time intervals. Furthermore, it is possible to increase the processing rate for prediction data updating and processing the received data at the end of the corresponding time segment approximation. The above configuration makes it possible, in particular, indicate the degree of achievement of objectives based on the latest data for consumers.

136[0080] The expression "indicating the difference between the predicted energy consumption and the set point on a combined scale demand" refers specifically to the situation in which indicated by a combination of scale, exceeds or not the predicted power consumption at a predetermined time setpoint demand, and / or whether there deviations, and moreover, the situation where there is excess or degree of such deviation is displayed on a combined scale. Specific explanations will be given in the example. For the case in which a predetermined value of demand during the period from 12:00 to 12:30 is 40 kWh, projected electricity consumption at 12:18 is 30 kWh. Accordingly, by the time scale on the combined indication it appears that there is a "deviation equivalent to 10 kWh with respect to the target demand."

137[0081] As an example, "Display ... via the combined scale", this difference can be expressed by a higher value than the value for the current time when the difference is positive and can be expressed by a lower value than the value for the current time when the difference is negative, provided that the difference between measured values ​​for the current time shown on scale combination. That is, when the difference is positive or negative, an indication is separate, distinct from the current time specified by a combination of the scale. In the case when the above difference is positive, the projected power consumption demand exceeds a predetermined value. In the case where the aforementioned difference is negative, the predicted power consumption value is less than a predetermined demand. In other words, the state in excess of the first case and the absence state in the second case an excess is indicated on a scale combined. In the case where the aforementioned power consumption continues at a rate above configuration shows the results explicitly whether or not exceed the predicted power consumption demand setpoint.

138[0082] The method for indicating the degree of difference (the percentage of the difference indicates a combined score) is determined using the unit power consumption for the set and the number of marks. FIG. 15 shows an example of displaying the difference operation means. The time interval is set lasting 30 minutes, from 10:00 to 10:30. Setpoint demand during this time interval is 60 kWh. If the power consumption after 20 minutes elapsed was 48 kWh, the predicted energy consumption by the end of this time interval is 72 kWh. The degree of excess consumption of 12 kWh. In this case, the number of marks on the scale at the time interval is 30, and each mark represents a difference 2 kWh from neighboring marks. Accordingly, in this case, a positive difference is represented by six marks after the mark corresponding to the value of the current time ((a) in FIG. 15). Conversely, if the energy consumption during the aforementioned time is 36 kWh predicted energy consumption by the end of the aforementioned time interval is 54 kWh. The degree of deviation of consumption of 6 kWh. Accordingly, in this case a negative difference is represented by three marks stamped before the corresponding value for the current time ((b) in FIG. 15). When users look at a predetermined display device demand, which reflected the results, in the first case, we can see the need for energy-saving measures to reduce electricity consumption by an amount equivalent to the value that will be consumed within a 6-minute period. In the latter case, it can be determined that there are abnormalities in the electric power consumption equivalent quantity consumed within 3 minutes. The above configuration relates to a method for the combined scale display, allows users to determine whether a given value is exceeded demand at the current time when looking at the display device is given in demand. It also allows users to determine the relationship between the power consumption at the current time and the target demand value by using specific numerical values. Thus, the above configuration clearly demonstrates the results, whether there is or exceeds the power consumption setpoint demand, and how much time should be used for energy-saving measures, so that users can avoid exceeding targets.

139[0083] The above steps are a sample. display methods are not limited to the above methods. More specifically, the same display can be performed based on all marks corresponding to the digits of the scale combined. Alternatively, for displaying it can be used, only the upper part of the marks or indicating excess deflection on the scale of the combined use. In addition, the positive or negative difference can be indicated by different colors. The above configuration makes it easy to recognize, even from a distance or not there is a positive or negative difference.

Explanation of the display device of predetermined demand fifth embodiment of the invention which are not included in the display device explanations given demand in FIG. 8 of the first embodiment and the like, are given hereinafter with a focus on display means difference.

142[0085] Specialized processing by displaying the difference means

143The CPU loads the data on energy consumption obtained by the program information about power consumption, executes arithmetic processing for calculating the energy consumed is projected to the end point of the interval for a given demand, compares and calculates the aforementioned processing results and information on a given value of demand, and stores the results of the address in the RAM.

144[0086] Subsequently, the CPU loads the information on projected electricity consumption and information on the specified value of the demand, work out differences display program calculates the difference between the projected electricity consumption and demand for a given value, and stores the results to the specified address in RAM. On the basis of this information about the difference processing is performed for the display on the combined scale.
