When is specified, the input unit of the setting information for the specified wireless device to be set is displayed.</p><p> For example, it is assumed that the wireless devices A, B, and C are specified and displayed in the layout diagram. When the wireless device A is designated as the wireless device to be set, the input unit of the setting information for the wireless device A is displayed. In this case, as the input unit of the setting information for the wireless device A, for example, the default value of the setting information is acquired from the storage unit of the actual wireless device A, and the input window of various setting information including the default value is displayed. Alternatively, the default value of the setting information according to the type of the wireless device A is acquired from the storage unit of the unique information setting device itself, and the input window of various setting information including the default value is displayed.</p><p> As a result, the desired wireless device is designated as the wireless device to be set from the wireless devices displayed in the layout diagram, and the input unit of the setting information for the wireless device to be set is displayed, and this setting is made. It is possible to input desired setting information (unique information) to the wireless device to be set from the information input unit.</p><p> Further, in the present invention, the unique information setting device is provided with the setting information transmitting means, and when the desired setting information is input to the setting information input unit and the input of the setting information is confirmed, the confirmed setting information is input.

In this case, an arbitrary position away from the first measurement point PA is set as the second measurement point PB, and the unique information setting device 2 is moved to the second measurement point PB. Then, the position of the second measurement point PB is marked on the floor layout diagram G1 (Fig. 4: Arrow (5)). Then, as shown in FIG. 7, a mark MB indicating the position of the second measurement point PB is displayed in the floor layout diagram G1.

Then, the operator sets the input field PW of the measurement point to "point PB" and clicks the measurement start button BT1 with the mouse. Then, the unique information setting device 2 transmits a return command of the physical identifier to the wireless device 1 (1-1, 1-2, 1-3) within the communicable range (Fig. 4: Arrow (6)). In response to the return command of the physical identifier from the unique information setting device 2, the wireless devices 1-1, 1-2, 1-3 within the communicable range are set to the physical identifiers # 1, # 2, Return # 3 (Figure 4: Arrow (7)).

When the physical identifiers # 1, # 2, and # 3 are returned from the radio wave devices 1-1, 1-2, 1-3 within the communicable range, the unique information setting device 2 has the physical identifiers # 1, # 2 , # 3 reception signal strength (received signal strength) V1B, V2B, V3B are measured, physical identifier # 1 and received signal strength V1B are paired, and physical identifier # 2 and received signal strength V2B are paired. , The physical identifier # 3 and the received signal strength V3B are paired, and the pair of these physical identifiers and the received signal strength is stored as the measurement result at the second measurement point PB.

Then, the message display column MS notifies that the measurement at the third measurement point PC has been completed.

[Procedure 5: Identifying the position of the wireless device] When the unique information setting device 2 completes the measurement at the third measurement point PC, the physical identifier # 1, included in the measurement result is automatically based on the measurement results at the measurement points PA, PB, and PC. The position of the wireless device 1-1,1-2,1-3 that returned the physical identifier for each # 2 and # 3 is specified, and the specified wireless device 1-1,1-2,1-3 The position is displayed in the floor layout diagram G1 (Fig. 4: Arrow (11)). Figure 9 shows the positions of the wireless devices 1-1, 1-2, 1-3 displayed in the floor layout diagram G1. The positions of wireless devices 1-1, 1-2, 1-3 are indicated by marks M1, M2, M3.

In this case, for example, the position of the wireless device 1-1 that has returned the physical identifier # 1 is specified as follows. For the physical identifier # 1, the received signal strength V1A at the first measurement point PA, the received signal strength V1B at the second measurement point PB, and the received signal strength V1C at the third measurement point PC. Is remembered. Estimate the distances R1A, R1B, and R1C between the wireless device 1-1 that returned the physical identifier # 1 from the received signal strengths V1A, V1B, and V1C and each measurement point PA, PB, and PC.

Then, from the estimated distances R1A, R1B, and R1C, the position of the wireless device 1-1 is specified by an algorithm such as a three-sided positioning method (see FIG. 10). In the same manner, the position of the wireless device 1-2 that returned the physical identifier # 2 and the position of the wireless device 1-3 that returned the physical identifier # 3 are also specified.

[Procedure 6: Specifying the wireless device to be set] The operator designates a desired wireless device as the wireless device to be set from the wireless devices 1-1, 1-2, 1-3 whose positions are displayed in the floor layout diagram G1. In this example, the wireless device to be set is the wireless device 1-2, and the mark M2 indicating the position of the wireless device 1-2 is clicked with the mouse (Fig. 4: Arrow (12)). The display color of the mark M2 changes when the mouse is clicked.

[Procedure 7: Obtaining the default value of setting information from the wireless device to be set] Then, the unique information setting device 2 adds the physical identifier # 2 of the wireless device 1-2 to be set, and defaults the setting information for the wireless device 1 (1-1 to 1-3) within the communicable range. Send a request to send a value (Figure 4: Arrow (13)).

The wireless devices 1 (1-1 to 1-3) within the communicable range receive the transmission request of the default value of the setting information from the unique information setting device 2, and the physical identifier # 2 attached to the transmission request. Judge whether or not it matches the physical identifier set for itself.

In this case, in the wireless device 1-2 to be set, it is determined that the physical identifier # 2 added to the transmission request and the physical identifier # 2 set in the self match. As a result, the wireless device 1-2 to be set responds to the transmission request of the default value of the setting information from the unique information setting device 2, and the various setting information items stored by itself and the setting information for the setting information item. The default value of is returned to the unique information setting device 2 (Fig. 4: Arrow (14)).

The unique information setting device 2 acquires various setting information items returned from the wireless device 1-2 to be set and default values of setting information for the setting information items, and inputs various setting information including the default values. Display W1 (see Figure 11) next to Floor Layout Figure G1 (Figure 4: Arrow (15)).

In this example, in the input window W1 of various setting information, the setting information items are "controller name", "logical address (management address)", "interlocking control method", "operation state at power recovery", and "setback operation". "Command" and "Room temperature setting method" are displayed. The input fields for the setting information of "Controller name" and "Logical address (management address)" are blank, "Linked control method" is "Linked", and "Operation state at power recovery" is "Previous state". , "Setback operation command" is "with setback", and "room temperature setting method" is "annual cooling main setting", and default values are set in the input field of the setting information.

[Procedure 8: Input of setting information] The operator inputs desired setting information for the "controller name" and "logical address (management address)" in the displayed input window W1 for various setting information. If there is a need to change the "interlocking control method", "operation state at the time of power recovery", "setback operation command", and "room temperature setting method", change the setting information (Fig. 4: Arrow (16)). ).

[Procedure 9: Send setting information] Then, the operator clicks the confirmation button BT2 with the mouse after completing the input of the setting information from the input window W1 of various setting information (see FIG. 12). Then, the unique information setting device 2 determines that the input of the setting information to the wireless device 1-2 to be set is confirmed, and sets the setting information in the confirmed input window W1 to the wireless device 1-2 to be set. The physical identifier # 2 is added and transmitted to wireless devices 1 (1-1 to 1-3) within the communicable range (Fig. 4: Arrow (17)).

The wireless devices 1 (1-1 to 1-3) within the communicable range receive the setting information from the unique information setting device 2, and are set to the physical identifier # 2 attached to the setting information and themselves. Determine if it matches the physical identifier.

In this case, in the wireless device 1-2 to be set, it is determined that the physical identifier # 2 added to the setting information and the physical identifier # 2 set by itself match. As a result, the wireless device 1-2 to be set stores the setting information from the unique information setting device 2 as the unique information assigned to itself, and returns the ACK signal to the unique information setting device 2 (Fig. 4: Arrow (arrow (arrow)). 18)).

When the unique information setting device 2 returns an ACK signal from the wireless device 1-2 to be set, the message display field MS indicates that the setting of the unique information to the wireless device 1-2 to be set is completed. Inform.

In the above-described embodiment, the wireless device 1-2 is set as the setting target wireless device, but even when the setting target wireless device is set as the wireless device 1-1, the wireless device 1-2 is set as the setting target wireless device. It is possible to set the unique information to the wireless device 1-1 by the same procedure as in the case of. The same applies when the wireless device to be set is wireless device 1-3.

In this case, the input window W1 for various setting information continues to be displayed until the next wireless device to be set is selected on the floor layout diagram G1. Further, in this case, the wireless device for which the unique information has not been set can be identified by the display color of the mark indicating the position of the wireless device.

Further, in the above-described embodiment, the default values of various setting information items and the setting information for the setting information items are acquired from the wireless device to be set, but the memory of the unique information setting device 2 is stored in the memory of the wireless device 1. Various setting information items according to the type and default values of the setting information for the setting information item are stored, and various setting information items and the setting information items according to the type of the wireless device 1-2 to be set are stored in the memory. The default value of the setting information for may be read.

A sequence diagram in this case is shown in FIG. As can be seen in comparison with the sequence diagram shown in FIG. 4, in the sequence diagram shown in FIG. 13, the request for transmitting the default value of the setting information to the wireless device 1-2 to be set is omitted (the arrow in FIG. 4 (arrow (arrow in FIG. 4)). 13)), various setting information items according to the type of wireless device 1-2 to be set and the default values of the setting information for the setting information items are read from the memory of the unique information setting device 2 itself, and the default values are used. The input window W1 for various setting information including is displayed (Fig. 13: Arrow (13)). Others are the same as the sequence diagram shown in FIG. 4, and the description thereof will be omitted.

As can be seen from the above description, according to the present embodiment, based on the measurement results at the three measurement points, the position of the wireless device that has returned the physical identifier for each physical identifier included in the measurement results is determined. Since it is specified and the position of the specified wireless device is displayed in the floor layout diagram, it becomes possible to find the desired wireless device even when the installation location of the wireless device is unclear.

Further, according to the present embodiment, when a desired wireless device is designated as a wireless device to be set from the floor layout diagram, input windows for various setting information for the designated wireless device to be set are displayed, and various of these are displayed. Since the unique information for the wireless device to be set can be set from the setting information input window, the correspondence between the physical identifier of each wireless device and the unique information assigned to that wireless device is not registered in the unique information setting device. However, troublesome registration work becomes unnecessary.

Further, according to the present embodiment, the setting information input from the input window of various setting information is transmitted to the wireless device within the communicable range by adding the physical identifier of the wireless device to be set, and is added to the setting information. Since the matching of the physical identifiers is confirmed and stored as unique information in the wireless device to be set, even if a plurality of wireless devices coexist within the communicable range of the unique information setting device, the desired wireless device is used. Unique information can be set correctly only for the device.

14 and 15 show functional block diagrams of the main parts of the unique information setting device 2 and the wireless device 1 in the unique information setting system described with reference to the sequence diagram of FIG.

In this method (method 1), the unique information setting device 2 includes a display unit 2A, a layout diagram storage means 2B for storing a layout diagram, a layout diagram display means 2C, an identification information return command transmission means 2D, and identification information. It includes a receiving means 2E, a received radio wave intensity measuring means 2F, a measurement result storing means 2G, a wireless device position specifying means 2H, a setting information input unit display means 2I, and a setting information transmitting means 2J. The wireless device 1 includes an identification information return means 1A, a default value transmission means 1B for setting information, a unique information storage means 1C, and a storage unit 1D for storing default values of various setting information.

[Unique information setting device] In the unique information setting device 2, the layout diagram display means 2C reads out the layout diagram of the designated area from the layout diagram storage means 2B and displays it on the display unit 2A. When the identification information return command transmitting means 2D is instructed to start measurement after designating its own current position as a measurement point in the layout diagram displayed on the display unit 2A, the identification information return command transmitting means 2D notifies the wireless device 1 within the communicable range. Sends a command to return the identification information set in the wireless device.

The identification information receiving means 2E receives the identification information returned from the wireless device 1 within the communicable range in response to the return command from the identification information return command transmitting means 2D. The received radio wave intensity measuring means 2F measures the radio wave strength (received radio wave strength) at the time of receiving the identification information with respect to the identification information received by the identification information receiving means 2E. The measurement result storage means 2G pairs the identification information and the received radio wave intensity of the identification information for each identification information received by the identification information receiving means 2E, and stores the identification information as the measurement result at the measurement point.

The wireless device position specifying means 2H is the position of the wireless device 1 that has returned the identification information for each identification information included in the measurement results based on the measurement results at the three measurement points stored in the measurement result storage means 2G. Is specified, and the position of the specified wireless device 1 is displayed in the layout diagram on the display unit 2A.

When the desired device is designated as the wireless device to be set, the setting information input unit display means 2I uses the wireless device 1 whose position is specified in the layout diagram of the display unit 2A. The input unit of the setting information for the specified wireless device to be set is displayed on the display unit 2A.

In this case, the setting information input unit display means 2I sends a transmission request of the default value of the setting information to the wireless device within the communicable range by adding the identification information of the wireless device to be set, and in response to this, the wireless device to be set is set. Acquires the default value of the setting information sent from the device, and displays the input window of various setting information including the default value as the input part of the setting information.

When the desired setting information is input to the setting information input unit displayed on the display unit 2A and the input of the setting information is confirmed, the setting information transmitting means 2J sets the confirmed setting information to the wireless setting target. The device identification information is added and transmitted to the wireless device 1 within the communicable range.

[Wireless device] In the wireless device 1, the identification information returning means 1A returns the identification information set by itself in response to the identification information return command sent from the unique information setting device 2 to the unique information setting device 2.

The default value transmission means 1B of the unique information responds to the transmission request of the default value of the setting information from the unique information setting device 2, and the identification information added to the transmission request of the default value of the setting information is set by itself. If it matches the identification information, the default values of various setting information stored in the storage unit 1D are returned to the unique information setting device 2.

The unique information storage means 1C receives the setting information from the unique information setting device 2, and when the identification information added to the setting information matches the identification information set by itself, the received setting information Is stored as unique information assigned to itself.

16 and 17 show functional block diagrams of the main parts of the unique information setting device 2 and the wireless device 1 in the unique information setting system described with reference to the sequence diagram of FIG.

In this method (method 2), the unique information setting device 2 includes a storage unit 2K that stores default values of various setting information according to the type of wireless device, and the setting information input unit display means 2I is designated. The default values of various setting information according to the type of the wireless device to be set are read from the storage unit 2K, and the input unit of the setting information for the wireless device to be set is displayed on the display unit 2A.

In this method, the wireless device 1 does not include the default value transmitting means 1B of the setting information and the storage unit 1D for storing the default values of various setting information as shown in FIG.
