First, when the remote monitoring device 200 installed in the property is activated, the remote monitoring device 200 sends the air conditioning control device 100 an ID for identifying the remote monitoring device 200 and the remote monitoring device 200. Information including an ID for identifying the air conditioner 300 and air quality sensor 400 installed in the same property is transmitted. The collection unit 101 receives the transmitted information, and identifies the base station 500 from which the remote monitoring device 200 has received radio waves from the received information. Then, the collection unit 101 associates the ID of the identified base station 500 with the IDs of the remote monitoring device 200, air conditioner 300, and air quality sensor 400, and registers them in the configuration data table shown in FIG. .

Note that the threshold value can be arbitrarily set by the administrator of the air conditioning control device 100. Information on the set threshold value is stored in the storage unit 102.

For example, the threshold value for the amount of PM2.5 per hour is set to "35 ug/m ³ ," and the threshold value for the amount of pollen per hour is set to "49 pieces/cm ³ ." If the amount of PM2.5 or pollen per hour exceeds the threshold value indicated by the information stored in the storage unit 102, the determination unit 103 determines that the local air condition has deteriorated. For example, if the status data indicated by the record in the first row of the table in FIG. It is determined that the condition has not worsened. On the other hand, if the status data indicated by the record in the second row of the table in FIG. It is determined that

The identification unit 104 in FIG. The monitoring device 200 identifies the base station 500 based on the location of the base station 500 receiving radio waves.

Further, the control unit 105 controls the identified air conditioner 300 so that the ventilation amount is reduced. The ventilation amount is, for example, the amount of air sucked from outside the air-conditioned space supplied into the air-conditioned space, or the amount of air sucked from inside the air-conditioned space discharged outside the air-conditioned space, or It's both. For example, the control unit 105 assigns the air conditioner ID "300-1-1" to the remote monitoring device 200 with the remote monitoring device ID "200-1-1", . . . , "200-1-N". , ..., transmits a control signal to reduce the ventilation amount of the air conditioner 300 of "300-1-N". A control signal that reduces the amount of ventilation is, for example, a control signal that reduces the amount of air sucked in from outside the air-conditioned space supplied into the air-conditioned space, or a control signal that reduces the amount of air sucked in from outside the air-conditioned space into the air-conditioned space. This is a control signal that reduces the amount of air supplied and the amount of air sucked in from the air-conditioned space and discharged outside the air-conditioned space.

The collection unit 101 collects state data from the air quality sensor 400 (step S101). The determining unit 103 determines whether the local air condition has deteriorated based on the condition data collected from the air quality sensor 400 and a predetermined standard (step S102). Specifically, the determination unit 103 determines whether the value indicated by the collected state data exceeds the threshold value indicated by the information stored in the storage unit 102.

When the determination unit 103 determines that the air condition in the area has deteriorated (step S102; YES), the identification unit 104 determines that the air conditioner installed in the property included in the area where it has been determined that the air condition has deteriorated. 300 is specified based on the position of the base station 500 from which the remote monitoring device 200 installed in the same property as the air conditioner 300 receives radio waves (step S103). Then, the control unit 105 transmits a control signal to turn on the air purification function and a control signal to reduce the ventilation amount to the specified air conditioner 300 (step S104). On the other hand, if the determining unit 103 determines that the local air condition has not deteriorated (step S102; NO), the process ends.

According to this embodiment, air conditioners installed in properties included in the same area can be identified without using a position detection device such as GPS. This makes it possible to provide remote monitoring and control services with a configuration that requires fewer devices.

Furthermore, according to the present embodiment, if one air quality sensor is installed in the communication area of one base station, the air condition in the area of the communication area can be estimated. This makes it possible to control the air conditioner according to the local air condition with a small number of devices.

Further, according to the present embodiment, when the air condition deteriorates, the air conditioner can clean the air in the air-conditioned space and limit the amount of ventilation. Thereby, the state of the air in the air-conditioned space can be made more reliably clean.
