  However, since the sensor units 21a to 21c are provided in the present modification as described above, the parent device control units 13 and 16 of the first and second position detection devices 2 and 3 are operated by the operation PC 4. Based on the instruction, for example, the wireless communication unit 12 is controlled so as to transmit data such as a test frame to each lighting device 5 and the sensor units 21a to 21c, for example, sequentially or simultaneously, or each lighting device 5 and the sensor units 21a to 21c.

May be affected.

  In such a case, since the reception level of this data changes, for example, every transmission, it becomes difficult to accurately measure the reception level of the data. As a result, the accurate installation position of the luminaire 5 is determined. It may be difficult to detect.

  Therefore, the lighting control system 1 of the present embodiment matches the data reception sensitivity level or the data transmission level with the first and second position detection devices 2 and 3 in order to accurately measure the data reception level.

Processing is performed so as to correct the transmission output level or the reception sensitivity level.

  For example, when wireless communication is performed by the first or second position detection device 2 or 3, the reception level acquired by each is the transmission level of data transmitted from one position detection device and the other position that receives the transmission level. This is obtained by multiplying the detection sensitivity level of the detection device by the square of the distance to the first or second position detection device 2 or 3.

  At this time, if the reception sensitivity level or the transmission level is matched, it is possible to match the reception level of both by correcting one of the reception sensitivity levels or the transmission level.

  Note that such correction means is provided on the side of the device having the arithmetic processing unit and the storage unit, for example, the operation PC 4 or the first and second position detection devices 2 and 3 to perform correction processing. It ’s fine.

  For example, when correction means are provided on the first and second position detection devices 2 and 3 side, both the parent device control units 13 and 16 are controlled to perform this correction processing.

  Specifically, the base unit control unit 13 of the first position detection device 2 communicates with the base unit control unit 16 of the second position detection device 3 in advance so as to match the data transmission level, and the data is acquired. Correction processing is performed so that the reception level matches the reception level acquired by the second position detection device 3.

  Then, the first position detection device 2 outputs the corrected data to the operation PC 4 which is a device having arithmetic processing means and a storage unit (not shown). Then, the operation PC 4 obtains the installation positions (addresses) of the respective lighting fixtures 5a to 5i by performing arithmetic processing using arithmetic processing means based on the correction data.

  In addition, although this correction means demonstrated the structure provided in operation PC4 or the 1st and 2nd position detection apparatus 2 and 3 side, of course, it is corrected by the operator using input operation parts, such as operation PC. You may comprise so that it may do.

Next, a position detection method performed by the illumination control system configured as described above will be described with reference to FIG.
In the following description, it is assumed that the plurality of lighting fixtures 5a to 5i are arranged on the ceiling surface 50a in advance as shown in FIG. Of course, the configuration as shown in FIG. 7 in which at least one sensor unit 21 (21a to 21c) is provided instead of any one of the plurality of lighting fixtures 5a to 5i is also applicable. Is possible. Therefore, it demonstrates as what includes the sensor part 21 (21a-21c) in these lighting fixtures 5a-5i.

  Now, it is assumed that the worker uses the lighting control system 1 shown in FIG. 1 to detect the installation positions (addresses) of the respective lighting fixtures 5a to 5i necessary for grouping.

  Here, as shown in step S1 of FIG. 13, the worker shows the first position detection device 2 and the second position detection device 3 in FIGS. 1 and 2 (or FIGS. 7 and 8). As described above, the office 50 is installed on the ceiling surface 50a so as to be in a straight line at one corner. In this case, the operation PC 4 is connected to the first position detection device 2 using the connection cable 2a.

  Then, the operator measures the distance L between the first position detection device 2 and the second position detection device 3.

  Thereafter, the operator inputs the measured distance L data between the first position detection device 2 and the second position detection device 3 using the operation PC 4 after the lighting control system 1 is turned on. .

This procedure shows the input procedure.
The step S1 may be omitted. However, in this case, only the relative positional relationship of the lighting fixture 5 is calculated by the following steps S2 to S7.

  Then, as shown in step S2, the operator operates the operation PC 4 and executes a command indicating “measurement start”.

  Then, based on the command supplied from the operation PC 4, the base unit control unit 13 of the first position detection device 2 lists each of the lighting fixtures 5 constituting the position control target lighting control load unit, that is, each The wireless communication unit 12 is controlled so as to create list data of unique addresses assigned to the lighting fixtures 5 a to 5 i and transmit the list data to the second position detection device 3.

  Thus, when the base unit control unit 16 of the second position detection device 3 receives the list data via the transmission / reception antenna 14, the list data is stored and simultaneously measured from the first position detection device 2. The operation waits until a start command is received.

  The first position detection device 2 acquires the average value of the reception level obtained by transmitting and receiving correction data with the second position detection device 3 after the power is turned on as a reference value, and outputs it to the operation PC 4. It is supposed to be. In this case, the operation PC 4 stores this reference value in a storage unit (not shown).

  Then, the base unit control unit 13 of the first position detection device 2 designates one of the unique addresses of the created list data, for example, the test frame data for the lighting fixture 5a. The wireless communication unit 12 is controlled to transmit.

  Then, as shown in step S3, the wireless communication unit 7 of the luminaire 5a receives the transmitted test frame data via the transmission / reception antenna 6, and at the same time, the level measurement unit 7a determines the reception level of the received data. Measure and output the measurement result to the slave unit control unit 8.

  Thereafter, the handset controller 8 of the lighting fixture 5a creates frame data (hereinafter referred to as a return frame) including data of the reception level as the measurement result and the local address of the lighting fixture 5a. The wireless communication unit 12 is controlled so as to be returned to the first position detection device 2.

  In the process of step S4, the wireless communication unit 12 of the first position detecting device 2 receives the return frame returned from the lighting fixture 5a via the transmission / reception antenna 11, and at the same time, the level measurement unit 12a receives this return frame. The reception level is measured and the measurement result is output to the parent device control unit 13.

  The base unit control unit 13 of the first position detection device 2 controls the measurement result to be output to the operation PC 4 together with a return frame as a local reception level.

  Then, as shown in step S5, the operation PC stores the supplied data of the local station reception level and the return frame from the first position detection device 2 in the storage unit (not shown) as that of the lighting fixture 5a. .

  As described above, the base unit control unit 13 of the first position detection device 2 performs steps S2 to S5 for the lighting fixtures 5 from the lighting fixture 5b to the lighting fixture 5i of the next address in the list data. Control to perform processing sequentially.

  And after memorize | storing the data of the return frame to all the lighting fixtures 5a-5i and the local station reception level in the memory | storage part which is not shown in figure for operation PC4, operation PC4 is 1st position detection by the process of step S6. The wireless communication unit 12 of the device 2 is controlled to specify the position detection target lighting fixture 5 for the second position detection device 3, that is, the illumination at the address started by the first position detection device 3. While specifying the instrument 5a, a measurement start command is transmitted.

  Then, as shown in step S7, when the second position detection device 3 that has been in the operation standby state receives the measurement start command, similarly to the above, the steps from the step S2 to the step by the first position detection device 2 are performed. The process of S4 is performed sequentially, and the data of each reception level and each return frame based on each lighting fixture 5a-5i is acquired, respectively.

  Then, the base unit control unit 16 of the second position detection device 3 controls the wireless communication unit 15 so as to transmit the acquired data of each reception level and each return frame to the first position detection device 2. .

  The wireless communication unit 12 of the first position detection device 2 receives the data of each reception level and each return frame transmitted from the second position detection device 3, and then from these second position detection devices 3. Is output to the operation PC 4 by the parent device control unit 13 and stored in a storage unit (not shown) of the operation PC 4 in the same manner as described above.

  By operating in this way, the storage unit (not shown) of the operation PC 4 stores the distance L data between the first position detection device 2 and the second position detection device 3 input in advance and the reference value of the reception level. The reception level and return frame data of each of the first position detection device 2 and each of the lighting fixtures 5a to 5i, the reception level of each of the second position detection device 3 and each of the lighting fixtures 5a to 5i, and The return frame and data are stored. The processing from step S2 to step S7 shows the detection procedure.

  In the above description, the reception level received by the first position detecting device and the second position detecting device 3 and the radio signal transmitted from the first position detecting device and the second position detecting device 3 in each lighting device. It is configured to acquire both the reception level, but the data of the reception level used for position detection may be either one of the reception levels, or the average of both. Also good. In the following description, unless otherwise specified, the reception level includes the reception level on the luminaire side, the reception level on the first or second position detection device side, or the average of both.

  In the present embodiment, the first and second position detection devices 2 and 3 have been described so as to sequentially perform the processing of step S2 to step S4. However, the present invention is not limited to this. For example, You may control to perform the process of the said step S2-step S4 simultaneously, respectively.

  Specifically, the base unit control unit 13 of the first position detection device 2 transmits test frame data to the lighting fixtures 5a to 5i corresponding to all the unique addresses of the created list data. The wireless communication unit 12 is controlled.

  And the radio | wireless communication part 12 of the 1st position detection apparatus 2 receives all the return frames returned from the lighting fixtures 5a-5i via the transmission / reception antenna 11, and at the same time, these received return frames by the level measurement part 12a. , And the measurement result is output to the base unit control unit 13. The master control unit 13 controls the measurement result to be output to the operation PC 4 together with all the return frames as the local station reception level.

  Similarly to the first position detection device 2, when receiving the measurement start command, the base unit control unit 16 of the second position detection device 3 illuminates all the unique addresses of the created list data. The wireless communication unit 12 is controlled so as to simultaneously transmit test frame data to the instruments 5a to 5i.

  And the radio | wireless communication part 15 of the 2nd position detection apparatus 3 receives all the return frames returned from the lighting fixtures 5a-5i via the transmission / reception antenna 14, and at the same time, these received return frames by the level measurement part 15a. , And the measurement result is output to the base unit control unit 16. Thus, the second position detection device 3 acquires data of each reception level and each return frame based on each of the lighting fixtures 5a to 5i at a time. The master control unit 16 controls the measurement result to be output to the operation PC 4 together with all the return frames as the local station reception level.

In addition, a signal to be transmitted may be transmitted simultaneously by broadcasting a test frame including its own address without specifying a destination address. That is, the first position detecting device 2 may transmit a control signal to each lighting fixture 5 so as to make some reply to its own address. At this time, each luminaire returns the first address detection device 2 together with its own address, so that the first position detection device 2 transmits the radio signal transmitted from each luminaire 5 together with the address data of each luminaire 5. The reception level can be acquired.
An example of the reception levels obtained by the first and second position detection devices 2 and 3 in this way is shown in Table 1.

  That is, the reception level data acquired by the first and second position detection devices 2 and 3 necessary for obtaining the installation positions of the respective lighting fixtures 5a to 5i (including the sensor unit 21) by calculation processing is as shown in Table 1 above. There are two types as shown in FIG.

  However, the transmission and reception of test frame data and return frame data to all the lighting fixtures 5a to 5i (including the sensor unit 21) by the first and second position detection devices 2 and 3 are performed simultaneously, that is, two transmissions and receptions are performed simultaneously. By doing so, it is possible to obtain the two types of reception level data shown in Table 1 in a short time. For this reason, since the reception level data is detected in a short time under the same conditions, it is possible to reduce errors due to temporal fluctuations.

  In addition, the lighting control system 1 according to the present embodiment uses the correction unit, for example, the reception level acquired by the first position detection device 2 by transmitting / receiving data to / from the lighting fixture 5, and transmission / reception of data to / from the lighting fixture 5. Thus, processing is performed so as to correct the transmission level or the reception level of each data so that the reception level acquired by the second position detection device 3 matches.

  Thus, in the case of data transmission / reception performed between the first and second position detection devices 2 and 3 and the lighting fixtures 5a to 5i (including the sensor unit 21), at least the humidity in the room of the office 50 or the like. Even if the transmission / reception level of the transmission / reception data is affected by the temperature or temperature, the first and second position detection devices 2 and 3 are corrected so as to match the data reception level or transmission level. It is possible to measure the reception level.

  In this reception level correction processing, the control unit of the device having this correction means includes, for example, data such as a return frame obtained by transmission / reception with each of the lighting fixtures 5a to 5i (including the sensor unit 21). Superimposed device identification information (for example, flag 1 for a lighting fixture, flag 2 for a sensor unit 21, etc.) is detected, and a correction corresponding to the detection result is obtained from a correction coefficient table set in advance for each device identification information. A coefficient may be read out, and the reception level correction process may be controlled using the read out correction coefficient. Thereby, correction processing can be performed more easily and automatically.

  In this manner, the reception level data is acquired by the first and second position detection devices 2 and 3, and the data such as the reception level data is stored in the storage unit of the operation PC 4.

  Thereafter, as shown in step S8, the operation PC 4 stores the distance L data between the first position detection device 2 and the second position detection device 3 stored in a storage unit (not shown) and the reference value of the reception level. The reception level and return frame data of each of the first position detection device 2 and each of the lighting fixtures 5a to 5i, the reception level of each of the second position detection device 3 and each of the lighting fixtures 5a to 5i, and Data with the return frame is read out, and calculation processing is performed by an arithmetic processing unit (not shown) using the read data, and the installation positions (addresses) of the respective lighting fixtures 5a to 5i are obtained.

  For example, when the coordinates of the first position detection device 2 are used as a reference, the specific calculation process is defined as Z, where the distance between the first position detection device 2 and the second position detection device 3 is the first position. Distance X obtained by conversion from the reception level between the detection device 2 and the measurement target lighting fixture 5 (including the sensor unit 21), the second position detection device 3 and the measurement target lighting fixture 5 (including the sensor unit 21) ) And the distance Y obtained by conversion from the reception level, and the installation position x, y (in this case, x is the first position detection device 2) which is the coordinates of the lighting fixture 5 (including the sensor unit 21) to be measured. The distance from the first position detection device 2 on the line (x axis) connecting the second position detection device 3, and y is the measurement target from the x axis in the direction orthogonal to the x axis (y axis). If it is the distance to the lighting fixture 5 (including the sensor unit 21), the measurement pair Installation position x of the lighting apparatus 5 (including the sensor unit 21), y (address) is the following (Equation 1) and (Formula 2), can be obtained.
