FIG. 1 shows an outline of a system according to an embodiment of the present invention. This system is typically represented by 1 and contains multiple units or nodes 6,7,8,10,11,12,16,17,18,20,21,22. Some of these nodes, such as 6,7,8, are designed as controllers, such as control units, which allow control signals or other types of signals to be transmitted to one or more units or nodes in the system. Can be sent to U.
Units or nodes 10,11,12,16,17,18,20,21,22 are designed as controllable units or nodes that can be executed in response to control signals or similar forms of received signals. ing. Some or all of these units include radio frequency receiver / transceiver means, as shown. These units or nodes are located on subnets, eg 2,3,4, as shown. A subnet contains at least one unit that includes RF receiver or transmitter / receiver means. A subnet may contain only one node, but typically contains multiple units, such as at least two. The actual number of nodes or units in a subnet will depend on the actual application, the actual physical placement of the included units, or the utilization of the units. Units contained in a subnet, which may also be referred to as a power link arrangement, are connected to each other by a bus system, such as 15, 19, 23, as shown. The bus system may have a wired connection, which allows units within the subnet to communicate with each other, which will be further elaborated below.
As will be appreciated, the system may include more or less numbers than the three subnets shown, such as one, two, four, etc. subnets or powerlink arrangements.
Two of the illustrated controllers C, such as 6,7, are designed as remote control units, which have radio frequencies so that they can communicate with unit U with an RF receiver or transmitter / receiver. Equipped with a transmitter or transmitter / receiver. A system according to the present invention would have to include at least one controller capable of communicating with the unit, such as by RF signaling.
However, the system may also include other types of controller C, such as controller 8, which may include, for example, wired means by electrical signaling, or infrared signaling, other optical signaling, electromagnetic. A signal can be transmitted to one or more units U by means of signal transmission or the like.
Now, the operation of the system according to the present invention will be described in detail with reference to FIG. 2. This figure shows (a part of) a system having a subsystem having only one unit U having RF reception / transmission / reception means. The system includes, for example, multiple units or nodes 30,31,32,33 (U1-Un) including or connected to drive units for various devices 35,36,37,38. These devices may be a variety of activators and may be used in a variety of applications, as will be described in more detail later. These units may, or instead, include or be coupled to a variety of devices, measuring devices, indicating devices, controllers, etc. that need to receive information, control signals, etc. at any given time. .. A feature common to units 30, 31, 32, 33 is that it is necessary or advantageous to be able to transmit certain information, signals, etc. to the unit. Further, it may be necessary or desirable to be able to receive information or signals from the unit, such as confirmation signals, approval signals (ACK), and the like.
In the embodiment shown in FIG. 2, the unit 31 comprises receiving means for radio frequency signals, including, for example, antenna means 40. Each unit includes, for example, a motor drive unit or control unit and connects to each part 35,36,37,38 that is driven or controlled. As will be understood, the means driven, controlled, etc. by the unit may be integrated with the unit.
The system further includes a node in the form of a controller, such as a remote control unit 42 designed to transmit signals by radio frequency transmitting means, including an antenna means 43 and the like. This remote control unit may be used to transmit control signals or other types of signals to one or more units or nodes U1-Un in the system.
As shown, the system is at least one additional controller, eg, a remote controller 44, which, like the first remote controller, for example signals by radio frequency transmitting means including antenna means 45. Even if it is designed to transmit, or, unlike the first remote controller, it is designed to transmit by other means, such as wired means, infrared transmitting means, as described above. Good.
Units 30, 31, 32, 33 are connected by communication means 50 in the form of a wired communication bus, as shown and as described above. Communication may be carried out according to a predetermined protocol, whereby the means of communication 50 may of among a number of functions or services relating to the operation of the system, such as the reception and / or transmission of signals, the operation of each unit, etc. It can help to accomplish at least one or a combination of these. These features or services and their options are described in more detail below.
When a signal is transmitted from a controller, eg, a remote control device such as remote control device 42, the signal is one of units 30, 31, 32, 33 with RF receiving means in the first preferred embodiment. Received by, this unit will be designated as the master unit (unit 31 in the example shown). A received signal, such as a frame or data packet, contains information about a destination node, such as a target unit, such as an address, and the master unit 31 will determine where to receive each received signal.
If the recipient, or destination node, is the master unit itself, the master unit will operate according to the information contained in the received signal. If the source is one of the other units, eg unit 33, the master unit 31 will retransmit the received signal over communication channel 50 and according to the protocol for communication. Each 30 of the other units reads the signal, but only the unit addressed by the signal, such as unit 33, receives the signal and operates according to the payload data information contained in the signal, such as a command. Will.
The master unit, eg, unit 31, may include a table containing a list of addresses of all nodes or units contained in the system, ie, the subnet connected by the communication bus 50. This table is created when the subsystem is powered up. If such a table is created, the master unit will check whether the received signal, eg, the destination node contained in the frame of the received message, is located in the subnet associated with the master unit. You will be able to decide. If this is the case, the message will be retransmitted over communication bus 50. Otherwise, the message will not be retransmitted, for example because the destination node is on another subnet associated with the system. If the destination node is the unit itself, that is, the unit that received the RF signal, the message will not be retransmitted. The creation of such a table may be omitted, in which case all signals will be retransmitted, which may result in unnecessary retransmissions, but the data processing and storage will be Can be avoided / reduced.
The signal transmitted from the remote controller, eg 42, may be directed to more than one unit, or all units. In this case, the signal will be received by the master unit, eg 31, 31 as described above, and the destination node, eg, the receiver of interest, will be determined by the master unit. The signal may be retransmitted to the other unit in question via the communication bus 50, and the unit may execute the instructions contained in the signal.
In a modified example of the present embodiment, the master unit, for example, the unit provided with the RF receiving / transmitting / receiving means may sequentially operate the instructions included in the received signal. When a signal is received, the master unit determines the receiver of interest and often the type of instructions contained in the signal, eg, often associated with each receiver of interest. Will do. Based on this information, according to the protocol, and often according to other predetermined rules for the operation of the system in question, the master unit retransmits the signal, eg, individually, including individual addresses and corresponding instructions. Signals may be transmitted sequentially or at individual and / or predetermined time intervals.
In addition, the transmission of individual control signals may be performed according to certain rules, as described above. For example, when a given first signal is retransmitted to the first unit, the transmission of the next signal to the second unit, the reception of a signal from the first unit, for example, the first signal. It may be executed in response to a signal confirming and confirming that the instruction has been executed, or a signal indicating that the instruction has not been executed. The next signal can then be transmitted, but in many cases it may be after a predetermined time interval. Other rules may be defined.
Further, the operation of the system according to the communication protocol is preceded by the processing of control signals transmitted from two or more remote control devices and / or multiple control signals transmitted from a single remote control device, for example, the system. Processing of the control signal, eg, a control signal transmitted while actually performing an operation relating to the control signal from another remote control device associated with the same remote control device or system, may be included.
In such an environment, the master unit, eg, a unit equipped with RF receiving and / or transmitting and receiving means, may perform its operation according to predetermined rules that can be negotiated with respect to actual application and actual need. For example, the master unit may, of course, complete its current operation before investigating further received signals and operating according to those signals. Instead, the master unit subsequently determines the address and control content of the received signal, suspends some or all of the current operation according to predetermined rules, and the operation indicated by the subsequently received signal. You may start some or all of. This can be the case, for example, when a subsequently received signal requires an action that contradicts the current action. For example, in a system that includes an operable window, the current operation involves opening at least one window, and the next signal received indicates the closing of at least that same window.
As shown in FIG. 3, two or more units or nodes 30-33 in a subunit or powerlink arrangement are antenna means 40,46,47 for receiving control signals from, for example, remote controllers 42,44. A means having, 48 may be included.
In this case, related units, such as units designed to receive RF signals and connected to the same subnet, will operate under the same conditions, i.e., these units are themselves master units. Will not be specified as. Units with RF receiving means will help each other, because the signal transmitted from the remote controller is better than if only one unit in the subnet could receive the RF control signal. , Because it will be more likely to be received by at least one of these units (correctly, for example, checked by CRC (Cyclic Redundancy Check, Cyclic Redundancy Check)). This is caused by subnet units where RF signal damping can occur, such as walls or other building structures, fixtures, etc., and between nodes, such as controllers and subnet units. This is especially important when placed where the damping can occur due to the distance between them. In these cases, the transmitted control signal is "free line of sight" to one of the units equipped with RF receiving means, eg, the remote controller, or to the remote controller. ) (Free field of view line) could be picked up by the unit. The unit that receives the signal determines the destination node, checks the address table for the destination address, the destination node is associated with the subnet, and the destination node is, as described earlier. If not the unit itself, it will retransmit signals such as frames or data packets. If the unit does not contain an address table, in all cases mentioned above, the signal will be retransmitted over the communication bus 50.
However, if two or more units with RF receiving means, such as RF nodes, receive the transmitted control signal accurately (eg, checked by CRC), then all of these units are Will be prepared to retransmit the signal. According to the present invention, the RF node that receives the signal will randomly select a time slot. The system according to the invention can operate in, for example, 32 time slots, and the RF node that receives the signal will choose one of these. When each time slot occurs, the RF node will start retransmitting over communication bus 50. The RF node that selects the lowest numbered time slot, i.e. the earliest occurring time slot, will retransmit signals, such as frames or packets. Other RF nodes that also receive the signal detect that the transmission is going through the communication bus, and randomly select a new time slot number, this time slot occurs and the communication bus is free. Will try to send when you are.
If two (or more) RF nodes choose the same time slot number, they will try to transmit at the same time. However, the system has a collision detector, in which case transmission will be interrupted. Each RF node attempting to retransmit the received signal randomly selects a new timeslot number, and retransmits is performed by the node that selects the lowest timeslot number, as described above. Will be done. However, when a new time slot number is selected, the number of time slots may be increased, for example doubled, to reduce the chance of new collisions. This procedure may be repeated if a new conflict arises.
A node in the process of starting or executing transmission of a received signal, if it detects that a signal to be transmitted, such as a frame, has been received, for example, in the buffer of the node's receiver. Will stop sending. This would happen if another node had already retransmitted the signal, eg, a frame with the same content. Also in such cases, a system according to the invention will prevent signals, such as frames or data packets, from being unnecessarily retransmitted (one or more more times in the "original" retransmission).
As will be understood, the same process, such as selecting the number of time slots, may be performed by an RF node, which is the only RF node associated with the subnet. That is, the RF node may be designed in the same manner regardless of actual use.
When a destination node on a subnet receives a signal, eg, a frame, a response, eg, an acknowledgment (ACK), a measurement, etc., must typically be sent back from the destination node to a controller, eg, a remote control unit. This response will be sent along the same route as the received signal, eg the control signal, according to the protocol for communication.
Here, it can be explained with reference to FIG. Subnet 3 includes two nodes with RF receiving means, such as 16,17, and the control signal is assumed to be transmitted from the remote controller 6 with unit 18 as the destination node. The signal is (correctly) received by, for example, RF node 16 and retransmitted to node 18 via communication bus 19. The response signal from node 18 will be sent back to remote controller 6 via RF node 16. Since the control signal was received by RF node 16 instead of RF node 17, the transmission between node 16 and controller 6 is expected to have a positive result again, so the response back to the remote controller. It can be expected that the ratio of successful transmission will be relatively high with respect to the signal.
The embodiment shown in FIG. 3 will have the following advantages. That is, the control signal transmitted by the remote control device from a location that would give inappropriate reception at the position of the RF receiving means, eg, a unit equipped with 31, is instead by another unit, eg 31, 32, 33. A system according to the described embodiment that may be received is a remote control device, or more precisely, a user-operated remote control device that is far away from or attenuated from one or more units. If installed in a location that provides a given transmission, it would improve the reception of control signals.
Controllable units or nodes according to the present invention, such as 10,11,12,16,17,18,20,21,22, will be described in more detail with reference to FIG. In this figure, the controllable unit or node is generally indicated by 30, and the main parts of the controllable unit embodiment according to the present invention are illustrated. As mentioned above, this unit includes a receiver for receiving control signals, preferably an antenna means 46 connected to a transmitter / receiver 51. As will be appreciated, according to the present invention, additional wired means may be used to transmit control signals to the unit 30, if found applicable. The receiver and / or transmitter / receiver means 51 is connected to the internal bus 52, for example, to connect to the processor means 53, the control means 54, and the power supply means 56. The processor means 53 is designed and / or programmed to perform according to a protocol according to the invention and / or according to user-specified and / or application specification conditions, including control of communication over the communication bus 50. To. The control means 54 is designed to perform the requested operation, such as control, response command, etc., and is connected to various devices (not shown in FIG. 4) by wire, wireless transmission 55, etc. May be good. The power supply means 56 can be supplied in various ways apparent to those skilled in the art, such as battery supply, trunk feed transformer supply, local DC power supply, eg 24V power supply, solar cell supply, and combinations thereof. , And other known power supply systems. Further, as will be appreciated, the power supply 56 may also power the control and operation of various devices connected to the unit.
A further embodiment of a controllable unit or node according to the present invention is shown in FIG. As mentioned above, the unit includes antenna means 46, receiver means 51, internal bus 52, processor means 53, control means 54 and power supply 56'. However, the power supply 56'is supplied with power from a common power supply bus 60 connected to the power supply unit 58, for example, a 2-core (cord) cable or the like via the connection portion 57. The power supply unit 58 may be common to all units or cords in subunits or power link arrangements according to the present invention. The power supply bus 60 also serves as a communication bus for communication between controllable units or nodes included in a subnet or power link arrangement according to the present invention. Communication may be performed by a number of methods that will be obvious to those skilled in the art, such as modulation communication, multiplex (super position) communication, and the like. The power source 56'may provide a connection between the unit 30 and the communication bus / power supply bus 60 via a connection 57, so that the communication signal is transferred to and from the internal bus 52. Acts as a filter means for.
Finally, a further embodiment will be described with reference to FIG. This figure shows a system including subnets or power concatenated arrangements according to the present invention in a manner corresponding to FIGS. 2 and 3.
Here, the communication between the controllable units 30-33 according to the present invention is performed via a separate and designated communication bus 50. This communication bus may operate by wired means. In addition, the power supply to units 30-32 and preferably also related devices 35-38 is a central / local power source connected to each unit / node / device via the power supply bus 62 and connection 64. Provided by 58.
Further, according to embodiments of the present invention, the methods and systems described are utilized to monitor and / or control power consumption and / or requirements or other (limited) resources relating to the operation of the system. This may be described in more detail below.
For example, the available power from the power supply unit 58 may actually be limited in view of the power supply unit and wiring, such as peak current, rated power value, and the like. So, as you will understand, if, for example, two electric motors that provide operating power to two of devices 35-38 operate at the same time, then the power supply and wiring should correspond to this. Power savings can be achieved if such simultaneous loads can be avoided, as they will have to be designed and estimated, and will be understood there.
According to an important aspect of the invention, a node on a subnet may be designated as a resource master, for example, to limit the consumption of scarce and / or limited resources. Such resources may be, for example, available power (see those described above), but other types of resources may be subject to resource master control according to this embodiment of the invention.
The node designated as the resource master may be selected according to certain rules, for example, the node with the lowest or highest address on the subnet. Other means of designating a node as a resource master (which may be obvious to those skilled in the art) may be used.
When a node on a subnet receives a command indicating that it will have to supply a certain amount of limited resources, eg 1 A of current, needed to operate an electric motor. The node in question will have to send a request to the resource master over the communication bus. The resource master will determine the available resources, for example, considering that other nodes are using the resource at the same time or requesting that it be used at the same time. .. If the required resource is available, the resource master will reply to the requesting node that the required resource is available. If the requested amount of resources is not available, the requesting node will be told to wait. When the resources it needs become available, the resource master will tell the requesting node that it can now start working.
However, requests from nodes may also include priority, which means that if other nodes are currently using resources for low priority operation, eg power. The master suspends one or more of these low-priority operations, thereby making the required amount of resources available to the node with the higher-priority request. Can be done. Upon completion of the higher priority operation, the resource master informs the interrupted node or nodes that the requested power is now available again and can proceed. There will be. Priority is related to the actual behavior that the requesting node wants to perform, not the node itself. For example, a node requesting to use power to close a window because a rainfall sensor has signaled that it is raining is a node requesting power to operate, such as window blinds. It may have a higher priority.
As will be understood, if such power consumption control (or control of another resource) must be performed, the system or subnet in question is a list of addresses of units in the subnet, and many more. In the case of, it will be necessary to store a table containing other information, such as rated power consumption, functionality of related controlled devices, etc. Further, as will be understood, the communication bus provides a means for communicating requests, control signals, responses from the resource master, etc., and all nodes connected to the same power source of the resource, such as All nodes on the subnet will be controlled by the resource master.
The question is whether certain security or safety aspects, such as certain remote controls, such as unlocking doors, opening windows, etc., may be performed when operating devices and the like associated with controllable units. May be. In such an environment, a system according to the present invention is configured to provide that upon receiving a control signal from a particular controller, it imposes on the destination node a decision as to whether a particular device can operate. You may. That is, the level and parameters of security can be determined by setting up controllable nodes that operate a particular device. Therefore, transmission and retransmission are not involved in such security and / or safety aspects.
Although the present invention has generally been described above, the present invention is particularly advantageous in the context of remote control of devices related to buildings, homes, etc. where there may be obstacles to the transmission of RF signals. You can understand what you get. Such a device may be, for example, a controlled aperture member such as an operable window, door or the like having a member that can be opened and closed. Further, the present invention may be used with respect to any member associated with, for example, a window, door, or similar aperture member of a building, in which a movable member, such as a curtain, blind, etc., may be actuated. It is desirable and / or advantageous to be able to.
As will be appreciated, the present invention is not limited to the particular examples described above and may be used in connection with a wide variety of applications. Further, as will be appreciated, a system according to the present invention may be designed in a number of embodiments within the scope of the invention specified in the claims.
