Embodiment 1 FIG.
(Description of Configuration of Embodiment 1)
FIG. 1 is a diagram illustrating an example of a schematic configuration of an air-conditioning system 1 according to Embodiment 1 of the present invention. As shown in FIG. 1, the air conditioning system 1 includes, for example, an air conditioning management device 3, an air conditioner 11, an outdoor unit 21, a remote controller 31, an environment controller 41, a temperature sensor unit 43, a human sensor unit 45, and the like. ing.

The air conditioning management device 3 manages various states of the air conditioner 11, the outdoor unit 21, the remote controller 31, the environment controller 41, the temperature sensor unit 43, and the human sensor unit 45, for example. The outdoor unit 21 forms a heat exchange cycle such as a refrigeration cycle by operating in cooperation with the air conditioner 11, for example. For example, the air conditioner 11 operates in cooperation with the outdoor unit 21 to form a heat exchange cycle such as a refrigeration cycle, and harmonizes air in an air conditioning target space (not shown). For example, the remote controller 31 supplies an operation signal corresponding to a user operation to the air conditioner 11 to control the air conditioner 11. The environment controller 41 manages various sensor units such as the temperature sensor unit 43 and the human sensor unit 45, for example.

Here, it is assumed that the remote controller 31 includes, for example, a temperature sensor, a human sensor, and the like (both not shown). Moreover, the structure of the air conditioning system 1 demonstrated above is an example, Comprising: It does not specifically limit to these. For example, as a sensor unit managed by the environment controller 41, a humidity sensor unit, an illuminance sensor unit, and the like may be provided. Further, the remote controller 31 may include a humidity sensor, an illuminance sensor, and the like (both not shown). The air conditioning system 1 may include a ventilation device, a lighting device, and the like.

That is, the target range of the sensor group may be included in the target range of the operation group, and the target range of the operation group may be included in the target range of the sensor group.

In the operation information storage area, for example, operation information supplied from any one of the air conditioning management device 3 and the remote controller 31 is stored. The operation information is, for example, information for operating the air conditioner 11, that is, one of operation commands. The operation information may be information for controlling other equipment 5 such as the outdoor unit 21.

In the sensor information storage area, for example, sensor information which is a sensing result of various sensors provided in the remote controller 31, the temperature sensor unit 43, and the human sensor unit 45 is stored.

The sensor correction information is, for example, a value set so as not to use the detection result of the human sensor. The sensor correction information is, for example, a value for adding or subtracting the detection result of the temperature sensor, and specifically, a value for correcting the set temperature according to the energy saving mode, the comfort mode, or the like.

In the group configuration information storage area, for example, logical correspondence relationships between operation groups and sensor groups as described later are stored.

That is, when the equipment 5 does not hold the sensor information of the same sensor group as the own device, it is assumed that there is a possibility that the equipment device 5 may hold the sensor information of a sensor group different from the own device. In such an assumption, the equipment 5 cannot perform control suitable for the environment with the sensor information it holds. Therefore, the equipment 5 corrects the sensor information. For example, even if the detection result of the human sensor detects that a person is in the room, the equipment 5 performs a correction process that invalidates the detection result.

(Step S74)
The equipment 5 executes processing based on the operation information and sensor information. For example, assuming that the equipment 5 is an air conditioner 11, the air conditioner 11 performs air conditioning control based on operation information and sensor information.

(Description of the effect of Embodiment 1)
As shown in FIGS. 4 and 5, the air conditioner 11 with ID [1] operates together with the air conditioner 11 with ID [2], the air conditioner 11 with ID [3], and the remote controller 31 with ID [51]. Belongs to [1]. Therefore, the air conditioners 11 of ID [1] to ID [3] are controlled according to the operation command of the remote controller 31 of ID [51].

Here, the room in which the air conditioner 11 with ID [1] is installed is partitioned by a partition. The ID [1] air conditioner 11 and the ID [51] remote controller 31, the ID [2] air conditioner 11, and the ID [3] air conditioner 11 are installed separately in partitions. Therefore, since the air conditioning environment differs in each partition, for example, even if the human sensor provided in the remote controller 31 with ID [51] detects the presence of a person, the space of the air conditioner 11 with ID [2] There is a possibility that no person is present in the space of the air conditioner 11 with ID [3].

Therefore, if the operation group and the sensor group are the same, the air conditioner 11 with ID [2] and the air conditioner with ID [3] are selected according to the detection result of the human sensor of the remote controller 31 with ID [51]. 11, the control that is assumed to be present is performed. As a result, useless driving may be performed.

Therefore, as described above, a sensor group is assigned to each partition. Specifically, the air conditioner 11 with ID [1] and the remote controller 31 with ID [51] are set in the sensor group [1], the air conditioner 11 with ID [2] is set in the sensor group [2], and The air conditioner 11 with ID [3] is set in the sensor group [3]. By setting the sensor group in this way, when the human sensor of the remote controller 31 with ID [51] detects the presence of a person, the air conditioner 11 with ID [1] performs control when a person exists. The air conditioner 11 with ID [2] and the air conditioner 11 with ID [3] perform correction to negate the detection result of the human sensor, for example, and perform control when the person is absent.

That is, the air conditioning system 1 can perform efficient control without requiring the air conditioning management device 3 by separating the operation group and the sensor group.

In the above description, although the operation group and the sensor group are separated, the various information to be transmitted and received is the same operation information and sensor information as in the case of only the operation group. Control can be performed without increasing the amount.

In other words, the air conditioning system 1 can reduce the installation cost, suppress useless energy consumption, and perform air conditioning control according to the environment.

With the above configuration, the air conditioning system 1 can reduce the installation cost, suppress unnecessary energy consumption, and perform air conditioning control according to the environment.

In the first embodiment, the control device 51 corrects sensor information when at least one sensor group is set from among the sensor groups and the sensor information is included in at least one sensor group. If the sensor information is not included in at least one sensor group, the sensor information is corrected.

In the first embodiment, the control device 51 transmits / receives operation information when belonging to the operation group, and transmits / receives sensor information when belonging to the sensor group.
