The control unit 16 periodically transmits a request signal. The control unit 16 uses the first state information returned from at least two or more wireless sensor devices 30 among the plurality of wireless sensor devices 30 and the second state information detected by the state detection unit 13, The operation of each air conditioner 20 is controlled. That is, the control unit 16 processes the first state information and the second state information by the set processing method, and generates a control signal for operation control of each air conditioner 20.

In the first embodiment, the control unit 16 includes the first state information returned from at least two or more wireless sensor devices 30 of the plurality of wireless sensor devices 30 and the second state detected by the state detection unit 13. An average value of information is obtained, and the operation of each air conditioner 20 is controlled using the obtained average value. In this way, the air conditioning control system 100 adds the first state information detected by the two or more wireless sensor devices 30 arranged in the air conditioning target area to the second state information detected by the state detection unit 13. In addition, by averaging, it is possible to realize air conditioning control in consideration of the air condition of the entire air conditioning target area.

However, in the air conditioning control system 100 according to the first embodiment, the number of installed wireless sensor devices 30 is not substantially limited as described above. For this reason, the air-conditioning control system 100 can change the priority according to the position in the air-conditioning target area according to the season or the time zone by appropriately turning on and off the respective power sources of the wireless sensor devices 30 provided. You may comprise as follows. That is, for example, the same number of wireless sensor devices 30 are arranged above and below the air conditioning target area, and in summer, several power sources among the wireless sensor devices 30 arranged above are connected. In the winter, a process may be performed in which several of the wireless sensor devices 30 disposed below are turned off. The power on / off process of each wireless sensor device 30 as described above may be performed by the control unit 16.

FIG. 2 is a plan view illustrating a case where a plurality of air conditioners 20 are installed in a plane on the ceiling of the room. FIG. 3 is a plan view illustrating a case where a plurality of air conditioners 20 are installed linearly on the ceiling of the room. 2 and 3, it is assumed that a plurality of air conditioners or ventilators as the air conditioner 20 are installed on the ceiling of a room such as a building. As shown in FIGS. 2 and 3, in the air conditioning control system 100, different air conditioning target areas may be set for each of the plurality of air conditioning devices 20. That is, as in the example of FIG. 2, the air conditioning target areas A, B, C, and D may be set in the room R1 according to the arrangement of the four air conditioning devices 20. Further, as in the example of FIG. 3, the air conditioning target areas X, Y, and Z may be set in the room R <b> 2 according to the arrangement of the three air conditioning devices 20.

In this case, the control unit 16 is configured to be able to grasp each air conditioning target area set in each of the plurality of air conditioning devices 20 and control each air conditioning device 20 individually. For example, in the storage unit 15, area information that associates each air conditioning device 20 with each wireless sensor device 30 disposed in each air conditioning target area is stored, and when controlling the operation of each air conditioning device 20, The control unit 16 may refer to the area information. Each air-conditioning target area may have overlapping areas as shown in FIGS.

Then, regarding the operation control of one air conditioner 20, each first state detected by the control unit 16 in the two or more wireless sensor devices 30 arranged in the air conditioning target area of the air conditioner 20. Configure to use information. That is, the control unit 16 acquires each first state information from two or more wireless sensor devices 30 arranged for each air conditioning target area, and uses each acquired first state information to set each air conditioner 20. Each is configured to be controlled individually. If it does in this way, the air-conditioning control suitable for the environment of each air-conditioning object area will be attained. In addition, about the installation number and arrangement | positioning location of the air conditioner 20, it can change suitably not only in the case of FIG.2 and FIG.3.

FIG. 4 is a flowchart showing the operation of the air conditioning control system 100. With reference to FIG. 4, the operation | movement regarding the information collection process and air-conditioning control by the polling method which applied the radio | wireless technique is demonstrated.

First, the control unit 16 transmits a request signal to a plurality of wireless sensor devices 30 wirelessly (FIG. 4: step S101). Each wireless sensor device 30 that has received the request signal returns the detected first state information to the control unit 16. Thereby, the control part 16 acquires each 1st state information (FIG. 4: step S102). Moreover, the control part 16 acquires 2nd state information from the state detection part 13 (FIG. 4: step S103).

And the control part 16 produces | generates the control signal for operation control of each air conditioner 20 based on each 1st state information and 2nd state information (FIG. 4: step S104). Next, the control unit 16 controls the operation of each air conditioner 20 by transmitting the generated control signal to each air conditioner 20 (FIG. 4: step S105).

The control unit 16 periodically transmits a request signal to the plurality of wireless sensor devices 30, generates a control signal when the second state information is returned from each wireless sensor device 30, and sends it to each air conditioner 20. Send. Thereby, the air-conditioning control system 100 can control operation | movement of each air-conditioning apparatus 20 regularly so that the environment in an air-conditioning object area may be in the optimal state.

In addition, although the said operation | movement was demonstrated in order of the number of the step in FIG. 4, it is not limited to the said order. For example, the control unit 16 may acquire the first state information and the second state information at the same time, or may acquire the second state information before the first state information.

As described above, in the air conditioning control system 100 according to the first embodiment, the control unit 16 has a polling function, and the wireless sensor device 30 can be disposed in the air conditioning target area without restriction. The control accuracy can be improved.

In other words, in the conventional air conditioning control system, it is assumed that each wireless sensor is arranged in a range that can be detected by the light receiving element of the indoor unit. Need to be placed.
In this regard, the air conditioning control system 100 can arrange the wireless sensor device 30 anywhere as long as wireless communication between the wireless sensor device 30 and the remote controller 10 is possible. And since the air conditioning control system 100 does not need to secure the memory capacity for performing the data collection by the polling method and holding the information indicating each wireless sensor device 30, the wireless sensor device 30 substantially There is no limit to the number of installations. Therefore, according to the air conditioning control system 100, the control unit 16 can collect data such as the temperature of the entire air conditioning target area, and can control the operation of each air conditioning device 20 based on the collected data. The air conditioning control of the entire air conditioning target area can be performed with high accuracy.

In addition, since the conventional air conditioning control system includes a light emitting element, a display device, an input switch, and the like mounted on a wireless sensor, the power consumption is large and the battery needs to be replaced in a relatively short time. In addition, the conventional air conditioning control system has a high cost per wireless sensor, and the cost of adding a wireless sensor also increases.
In this respect, the air conditioning control system 100 simply configures each wireless sensor device 30 as shown in FIG. 1, so the cycle of battery replacement can be extended and the cost can be reduced. In particular, if low-frequency BLE or the like is adopted as a wireless communication standard, the battery replacement cycle of the wireless sensor device 30 can be further extended, and the wireless sensor device 30 is continuously used for a relatively long time. be able to.

Embodiment 2. FIG.
FIG. 5 is a schematic diagram showing an overall configuration of an air conditioning control system according to Embodiment 2 of the present invention. FIG. 6 is a schematic view illustrating the priority table in the storage unit of FIG. FIG. 7 is a schematic view illustrating a weight table in the storage unit of FIG. FIG. 8 is a schematic view illustrating an identification weight table in the storage unit of FIG. The configuration and operation of the air conditioning control system according to the second embodiment will be described with reference to FIGS. The same components as those in the air conditioning control system 100 according to Embodiment 1 described above are denoted by the same reference numerals, and description thereof is omitted.

The air conditioning control system 200 according to the second embodiment includes a remote controller 110, a plurality of air conditioners 20, and a plurality of wireless sensor devices 130. Each of the plurality of wireless sensor devices 130 detects first state information indicating the state of the air at the disposed position, and each has the same configuration as shown in FIG. The wireless sensor device 130 includes a wireless communication unit 31, an information control unit 132, and a wireless detection unit 33.

Each of the plurality of wireless sensor devices 130 is configured to return its identification information along with the first state information in response to a request signal from the control unit 160 provided in the remote controller 110. The identification information is stored in an internal memory or the like (not shown) of the information control unit 132. That is, the information control unit 132 is configured to acquire the first state information from the wireless detection unit 33 and read the identification information from the internal memory or the like in response to a request signal from the control unit 160. Then, the information control unit 132 returns the first state information and the identification information to the control unit 160 via the wireless communication unit 31. Here, the identification information is an ID assigned to each of the plurality of wireless sensor devices 30.

In the second embodiment, each of the plurality of wireless sensor devices 130 is set with a weighting factor indicating the air conditioning priority of the disposed position. The control unit 160 weights each first state information returned from at least two or more wireless sensor devices 30 among the plurality of wireless sensor devices 30 according to a weighting factor, and each first state after weighting The operation of each air conditioner 20 is controlled using the information. In this Embodiment 1, the control part 160 calculates | requires the average value of each 1st state information after weighting, and 2nd state information, and it is comprised so that operation of each air conditioner 20 may be controlled using the calculated | required average value. Has been.

More specifically, the storage unit 150 associates each identification information of the plurality of wireless sensor devices 30 with a weighting factor indicating the air conditioning priority at the position where each of the plurality of wireless sensor devices 30 is disposed. Table information is stored. The control unit 160 is configured to read each weighting factor by comparing the identification information and each first state information returned from at least two wireless sensor devices 130 out of the plurality of wireless sensor devices 130 with the table information. Has been.

As the table information, for example, a priority table illustrated in FIG. 6, a weight table illustrated in FIG. 7, an identification weight table illustrated in FIG. The priority table is information in which the identification information and the air conditioning priority are associated with each other, and the weight table is information in which the air conditioning priority is associated with the weight coefficient. The identification weight table is information that directly associates identification information with a weight coefficient.

When the priority table and the weight table are stored as table information in the storage unit 150, the control unit 160 first checks the identification information transmitted from each of the wireless sensor devices 130 against the priority table. The air conditioning priority set for each wireless sensor device 130 is read. Next, the control unit 160 reads the weighting coefficient set for each wireless sensor device 130 by comparing the read air conditioning priorities with the weight table.

When the identification weight table is stored as table information in the storage unit 150, the control unit 160 compares the identification information transmitted from each of the wireless sensor devices 130 with the identification weight table, and each wireless sensor device 130. Read the weighting factor set for each of.

Further, the weight count may be stored in the internal memory of the information control unit 132 together with the identification information. Then, in response to the request signal from the control unit 160, the information control unit 132 reads the identification information and the weight count from the internal memory or the like, and sends the read identification information and weight count together with the first state information to the control unit 160. You may make it reply.

In addition, when the wireless sensor device 130 is added later, when the wireless sensor device 130 for which the air-conditioning priority is not set exists in the air-conditioning target area, the control unit 160 removes the wireless sensor device 130 from the wireless sensor device 130. The first state information transmitted is not weighted, and the first state information is used as it is for the generation of the control signal.

Furthermore, the air conditioning control system 200 may adopt a configuration in which a weighting factor based on a scale common to the plurality of wireless sensor devices 130 is set in the state detection unit 13. Then, the control unit 160 weights the second state information in accordance with the weighting factor set in the state detection unit 13, and controls the operation of each air conditioner 20 using the weighted second state information. May be. In this case, the control part 160 calculates | requires the average value about each 1st state information after weighting and the 2nd state information after weighting, for example, and controls the driving | operation of each air conditioner 20 using the calculated | required average value. In this way, since the operation control of each air conditioning device 20 can be performed in consideration of the position of the state detection unit 13, that is, the position of the remote controller 10, the accuracy of the air conditioning control can be further improved.

In addition, when the air conditioning priority is set for each of the plurality of wireless sensor devices 130, the control unit 160 has the wireless sensor device 130 with the highest priority among the wireless sensor devices 30 that have responded to the request signal. The operation of each air conditioner 20 may be controlled using only each first state information returned from the. That is, for example, when the air conditioning priority is set in three stages of “high”, “medium”, and “low”, the control unit 160 sets each of the first steps from the wireless sensor device 130 set to “high” and “medium”. One state information may be used.

Further, in the air conditioning control system 200, the wireless sensor device 130 can be additionally disposed in a place where the air conditioning priority is high or low. Therefore, since balance adjustment of each 1st state information detected by each wireless sensor apparatus 130 can be performed afterwards, the precision of air-conditioning control can be raised further.

Other configurations and operations are the same as those of the air conditioning control system 100 of the first embodiment described above. Therefore, the other configuration of the control unit 160 is the same as the control unit 160 in the first embodiment, and the other configuration of the wireless sensor device 130 is the same as the wireless sensor device 30 in the first embodiment.

As described above, in the air conditioning control system 200 according to the second embodiment, the control unit 160 has the polling function, and the memory capacity to be ensured is smaller than that in the past, so the wireless sensor device 130 is within the air conditioning target area. Can be disposed without limitation. Therefore, according to the air conditioning control system 200, the control unit 160 can collect data such as the temperature of the entire air conditioning target area, and can control the operation of each air conditioning device 20 based on the collected data. The air conditioning control of the entire air conditioning target area can be performed with high accuracy.

By the way, the air conditioning priority and the weighting coefficient of each wireless sensor device 130 may be changed according to the season in consideration of the fact that cold air accumulates downward. For example, in the summer season, the wireless sensor device 130 disposed above the air conditioning target area can be set to have a higher air conditioning priority or a larger weighting factor. In winter, the wireless sensor device 130 disposed below the air conditioning target area can be set to have a higher air conditioning priority or a larger weighting factor. In this way, the control unit 160 can generate a control signal that matches the user's sensible temperature and comfort based on the first state information detected by each wireless sensor device 30. The accuracy of air conditioning control can be further increased. In the case of adopting such a configuration, the input unit 12 of the remote controller 10 is configured to accept setting switching such as the air conditioning priority according to the season, and the user can input the air conditioning priority etc. by an input operation to the input unit 12. It is advisable to switch settings. Further, the control unit 160 may automatically perform setting switching such as the air conditioning priority according to the detection value by the state detection unit 13 or the wireless sensor device 130.
