The acquisition instruction transmission unit 206 is an example of the acquisition instruction transmission means.

When the management device 200 receives the sensor information from the indoor unit 100 that is not the collection device, the transfer unit 207 transfers the sensor information to the indoor unit 100 that is the collection device.

Next, the table generation process executed by the management device 200 will be described with reference to the flowchart of FIG. For example, when the air conditioning system 1000 is installed, the management device 200 starts executing the table generation process in response to receiving an instruction to start the table generation process from the contractor.

First, the control unit 21 included in the management device 200 selects the sensor terminal 300 (step S101). For example, the control unit 21 selects one sensor terminal 300 from the five sensor terminals 300 indicated by the sensor terminal management table. When the control unit 21 completes the process of step S101, the control unit 21 refers to the sensor terminal management table and determines whether or not the selected sensor terminal 300 is a server type (step S102).

When the control unit 21 determines that the selected sensor terminal 300 is a server type (step S102: YES), the control unit 21 instructs all the indoor units 100 to perform the server type measurement process (step S103). On the other hand, when the indoor unit 100 receives an instruction of the server type measurement process from the management device 200, the indoor unit 100 executes the server type measurement process shown in FIG.

First, the control unit 11 included in the indoor unit 100 selects one louver from the four louvers 17 (step S201).

That is, the control unit 11 controls the route switching unit 15 so that the antenna 18 installed in the selected louver 17 is connected to the wireless communication unit 14. When the process of step S202 is completed, the control unit 11 sets the angle of the louver 17 to the lower limit value (step S203). That is, the control unit 11 controls the louver drive unit 16 to set the angle of the selected louver 17 to 0 °.

When the control unit 11 completes the process of step S203, the control unit 11 acquires sensor information from the sensor terminal 300 (step S204). That is, the control unit 11 transmits the request information to the sensor terminal 300 and acquires the sensor information from the sensor terminal 300. When the processing of step S204 is completed, the control unit 11 measures the received signal strength (step S205). When the process of step S205 is completed, the control unit 11 determines whether or not the angle of the louver 17 is the upper limit value (step S206). The upper limit is 90 °.

When the control unit 11 determines that the angle of the louver 17 is not the upper limit value (step S206: NO), the control unit 11 increases the angle of the louver 17 by a specified value (step S207). The specified value is 5 °. When the control unit 11 completes the process of step S207, the control unit 11 returns the process to step S204. When the control unit 11 determines that the angle of the louver 17 is the upper limit value (step S206: YES), the control unit 11 saves the optimum angle and the received signal strength at the optimum angle (step S208). When the process of step S208 is completed, the control unit 11 determines whether or not there is an unselected louver 17 (step S209).

On the other hand, when the control unit 11 determines that there is no unselected louver 17 (step S209: NO), the control unit 11 transmits signal strength information to the management device 200 (step S210). The signal strength information is information indicating the optimum angle and the received signal strength at the optimum angle for each louver 17. When the control unit 11 completes the process of step S210, the server type measurement process is completed.

When the process of step S302 is completed, the control unit 11 sets the angle of the louver 17 to the lower limit value (step S303).

When the control unit 11 completes the process of step S303, the control unit 11 acquires the sensor information transmitted by the sensor terminal 300 a plurality of times (step S304). That is, the control unit 11 monitors the wireless communication unit 14 for a predetermined period. When the processing of step S304 is completed, the control unit 11 calculates the median value of the received signal strength (step S305). When the control unit 11 completes the process of step S305, the control unit 11 calculates the offset time and the communication cycle (step S306). When the process of step S306 is completed, the control unit 11 determines whether or not the angle of the louver 17 is the upper limit value (step S307).

When the control unit 11 determines that the angle of the louver 17 is not the upper limit value (step S307: NO), the control unit 11 increases the angle of the louver 17 by a specified value (step S308). When the control unit 11 completes the process of step S308, the control unit 11 returns the process to step S304. When the control unit 11 determines that the angle of the louver 17 is the upper limit value (step S307: YES), the control unit 11 saves the optimum angle, the received signal strength at the optimum angle, the offset time, and the communication cycle (step S309). When the process of step S309 is completed, the control unit 11 determines whether or not there is an unselected louver 17 (step S310).

When the control unit 11 determines that there is an unselected louver 17 (step S310: YES), the control unit 11 returns the process to step S301. On the other hand, when the control unit 11 determines that there is no unselected louver 17 (step S310: NO), the control unit 11 transmits the signal strength information and the communication timing information to the management device 200 (step S311). The communication timing information is information indicating the offset time and the communication cycle. When the control unit 11 completes the process of step S311, the broadcast type measurement process is completed.

When the control unit 21 completes the process of step S106, the control unit 21 acquires the signal strength information and the communication timing information from all the indoor units 100 (step S107). When the processing of step S107 is completed, the control unit 21 updates the signal strength management table based on the acquired signal strength information (step S108). When the processing of step S108 is completed, the control unit 21 updates the communication timing management table based on the acquired communication timing information (step S109).

When the processing of step S105 or step S109 is completed, the control unit 21 determines whether or not there is an unselected sensor terminal 300 (step S110). When the control unit 21 determines that there is an unselected sensor terminal 300 (step S110: YES), the control unit 21 returns the process to step S101. When the control unit 21 determines that there is no unselected sensor terminal 300 (step S110: NO), the control unit 21 executes the schedule management table generation process (step S111). Hereinafter, the schedule management table generation process will be described with reference to FIG.

First, the control unit 21 determines whether or not there is a sensor terminal 300 having a first priority (step S401). The first priority sensor terminal 300 is a broadcast type sensor terminal 300 in which the collecting device is the indoor unit 100. In the sensor terminal 300 having the first priority, it is difficult to change the timing of transmitting the sensor information, and since the indoor unit 100 in which it is desirable to acquire the sensor information is defined, various assignments are prioritized. ..

When the control unit 21 determines whether or not there is a sensor terminal 300 having a first priority (step S401: YES), the control unit 21 assigns the indoor unit 100 and the louver 17 to the sensor terminal 300 having the first priority (step S402). .. The control unit 21 basically assigns the indoor unit 100, which is a collection device, and the louver 17, which has the maximum received signal strength in the indoor unit 100, to the sensor terminal 300 having the first priority.

However, when the indoor unit 100, which is a collecting device, is already assigned to another sensor terminal 300 and the timings overlap, the indoor unit 100 having the maximum received signal strength among the indoor units 100 other than the collecting device, and the indoor unit 100, A louver 17 having the maximum received signal strength in the indoor unit 100 is assigned. In addition, assigning the louver 17 means assigning the optimum angle in the louver 17.

When the control unit 21 determines that there is no first priority sensor terminal 300 (step S401: NO), or when the process of step S402 is completed, whether or not there is a second priority sensor terminal 300. Is determined (step S403). When the control unit 21 determines that there is a second priority sensor terminal 300 (step S403: YES), the control unit 21 assigns the indoor unit 100 and the louver 17 to the second priority sensor terminal 300 (step S404). The second priority sensor terminal 300 is a broadcast type sensor terminal 300 whose collection device is the management device 200. In the sensor terminal 300 of the second priority, it is difficult to change the timing of transmitting the sensor information, but since the indoor unit 100 for which it is desirable to acquire the sensor information is not defined, various assignments are given as the first priority. It does not take precedence over the sensor terminal 300 of.

The control unit 21 basically assigns the indoor unit 100 having the maximum received signal strength and the louver 17 having the maximum received signal strength in the indoor unit 100 to the sensor terminal 300 having the second priority. However, if the indoor unit 100 having the maximum received signal strength is already assigned to another sensor terminal 300 and the timings overlap, the indoor unit 100 having the second highest received signal strength and the indoor unit 100 receive signals. The louver 17 having the maximum intensity is assigned to the sensor terminal 300 of the second priority. That is, the indoor unit 100 having the highest received signal strength among the indoor units 100 capable of receiving sensor information from the sensor terminal 300 having the second priority in terms of timing, and the louver 17 having the highest received signal strength in the indoor unit 100. Is assigned to the sensor terminal 300 of the second priority.

(Step S405). When the control unit 21 determines that there is a third priority sensor terminal 300 (step S405: YES), the control unit 21 assigns the indoor unit 100 and the louver 17 to the third priority sensor terminal 300 (step S406). The third priority sensor terminal 300 is a server type sensor terminal 300 in which the collecting device is the indoor unit 100. The sensor terminal 300 of the third priority can change the timing of transmitting the sensor information, but since the indoor unit 100 in which it is desirable to acquire the sensor information is defined, various assignments are given as the second priority. It is not prioritized over the sensor terminal 300 of the fourth priority, and is prioritized over the sensor terminal 300 of the fourth priority.

The control unit 21 basically assigns the indoor unit 100, which is a collection device, and the louver 17, which has the maximum received signal strength in the indoor unit 100, to the sensor terminal 300 having a third priority. However, when the indoor unit 100, which is a collection device, is already assigned to another sensor terminal 300, the offset time of the third priority sensor terminal 300 is adjusted so that the timings do not overlap. It is preferable that the communication cycle of the sensor terminal 300 having the third priority is not changed.

When the control unit 21 determines that there is no third priority sensor terminal 300 (step S405: NO), or when the process of step S406 is completed, whether or not there is a fourth priority sensor terminal 300. (Step S407). When the control unit 21 determines that there is a sensor terminal 300 having a fourth priority (step S407: YES), the control unit 21 assigns the indoor unit 100 and the louver 17 to the sensor terminal 300 having the fourth priority (step S408). The sensor terminal 300 of the fourth priority is a server type sensor terminal 300 in which the collecting device is the management device 200. Since the sensor terminal 300 of the fourth priority can change the timing of transmitting the sensor information and the indoor unit 100 for which it is desirable to acquire the sensor information is not defined, various assignments are made of the third priority. It does not take precedence over the sensor terminal 300.

The control unit 21 basically assigns the indoor unit 100 having the maximum received signal strength and the louver 17 having the maximum received signal strength in the indoor unit 100 to the sensor terminal 300 having the fourth priority. However, when the indoor unit 100 having the maximum received signal strength is already assigned to another sensor terminal 300, the offset time of the sensor terminal 300 of the fourth priority is adjusted so that the timings do not overlap. It is preferable that the communication cycle of the sensor terminal 300 of the fourth priority is not changed. When the control unit 21 determines that the sensor terminal 300 of the fourth priority does not exist (step S407: NO), or when the process of step S408 is completed, the control unit 21 completes the schedule management table generation process. When the control unit 21 completes the schedule management table generation process in step S111, the control unit 21 completes the table generation process.

When the control unit 21 determines that the sensor terminal 300 is a server type (step S502: YES), the control unit 21 transmits the sensor terminal information to the acquisition source indoor unit 100 (step S503). The sensor terminal information is information indicating the sensor terminal 300 from which the sensor information is transmitted.

When the control unit 21 determines that the sensor terminal 300 is not a server type (step S502: NO) or completes the process of step S503, the control unit 21 informs the indoor unit 100 of the acquisition source of acquisition instruction information, louver information, and angle information.

When the process of step S505 is completed, the control unit 21 determines whether or not it is necessary to transfer the sensor information (step S506). When the control unit 21 determines that it is necessary to transfer the sensor information (step S506: YES), the control unit 21 transmits the sensor information to the indoor unit 100 at the transfer destination (step S507). When the control unit 21 determines that the communication timing is not reached (step S501: NO), determines that it is not necessary to transfer the sensor information (step S506: NO), or completes the process of step S507, step S501 Return the process to.

That is, the control unit 11 adjusts the angle of the louver 17 indicated by the louver information to the angle indicated by the angle information.

When the control unit 11 completes the process of step S603, the control unit 11 determines whether or not the sensor terminal 300 is a server type (step S604). When the control unit 11 determines that the sensor terminal 300 is a server type (step S604: YES), the control unit 11 transmits transmission request information to the sensor terminal 300 (step S605).

When the control unit 11 completes the process of step S605 or determines that the sensor terminal 300 is not a server type (step S604: NO), the control unit 11 receives sensor information from the sensor terminal 300 (step S606). When the control unit 11 completes the process of step S606, the control unit 11 transmits the sensor information to the management device 200 (step S607).

When the control unit 11 completes the process of step S607, the control unit 11 returns the angle of the louver 17 to the original angle (step S608). When the control unit 11 completes the process of step S608, the control unit 11 resumes blowing air (step S609).
