In addition, the equipment mentioned here refers to the controller 2 and the wireless sensor 3.

[Case 1: Before equipment installation]
In case 1, as shown in FIG. 17, before installing a device on the site, system information of a system in which the device is installed is manually set in the VAV controller 2 and the wireless sensor 3. In this example, system information # 1 is manually set in the VAV controller 2-1 and the wireless sensor 3-1, and system information # 2 is manually set in the VAV controller 2-2 and the wireless sensor 3-2.

  However, according to the above-described method for defining the parent-child relationship between the VAV controller and the wireless sensor, in case 1, system information is set in the VAV controller 2 and the wireless sensor 3 before installing the equipment on the site. When the installation location of the sensor 3-1 is mistakenly installed on the system 2 side, the room temperature t2pv of the system 2 is sent to the VAV controller 2-1, and the control of the room temperature on the system 1 side is performed. It does n’t work.

  On the other hand, in case 2, system information is set in the VAV controller 2 and the wireless sensor 3 after the equipment is installed at the site. Therefore, when the VAV controller 2 is installed on the ceiling or the like, a ladder or the like is used. Therefore, it is necessary to perform setting work by approaching the VAV controller 2. For this reason, the setting work is troublesome and takes time. Even if the system information is correctly set before installation, if the system information is changed after installation, it is necessary to approach the VAV controller 2 to change the system information setting. Arise.

  Patent Document 2 discloses a wireless communication floor heating control system that can easily and reliably define a parent-child relationship between a control controller and a wireless sensor. In this wireless communication floor heating control system, as shown in FIG. 19, the room 4 is divided into two systems, a system 1 and a system 2, a hot water valve 5-1 is installed in the system 1, and hot water is installed in the system 2. The valve 5-2 is installed, hot water from the heat source unit 6 is supplied to the hot water valves 5-1 and 5-2, and floor heating in the system 1 and the system 2 is performed.

  In this case, the floor heating remote controller 7-1 with a built-in temperature sensor is installed in the system 1, the floor heating remote control 7-2 with a built-in temperature sensor is installed in the system 2, and the measured value t1pv of the floor heating temperature in the system 1 is obtained. The floor heating remote control 7-1 transmits to the heat source unit 6, and the floor heating temperature measurement value t2pv in the system 2 is transmitted from the floor heating remote control 7-2 to the heat source unit 6.

  The heat source unit 6 is provided with a control unit 6-1 that controls the opening degree of the hot water valve 5-1, and a control unit 6-2 that controls the opening degree of the hot water valve 5-2. The opening degree of the hot water valve 5-1 is controlled by the control unit 6-1 so that the measured temperature value t1pv matches the set value t1sp, and the measured floor heating temperature value t2pv in the system 2 matches the set value t2sp. Thus, the opening degree of the hot water valve 5-2 is controlled by the control unit 6-2. The controller 6-1 and the hot water valve 5-1 and the controller 6-2 and the hot water valve 5-2 are connected by wire.

  In this wireless communication floor heating control system, the parent-child relationship between the heat source unit 6 and the floor heating remote control 7 (the parent-child relationship between the control unit 6-1 and the floor heating remote control 7-1, the control unit 6 -2 and the parent-child relationship between the floor heating remote controller 7-2) is performed as follows. First, as shown in FIG. 20, a control command is sent from the heat source unit 6 to the hot water valve 5-1 by wire to open the hot water valve 5-1. And it inquires to floor heating remote control 7-1 and 7-2 by radio | wireless from the heat-source equipment 6 for every fixed time.

  In this case, the floor heating remote controller 7-1 detects a temperature rise within a predetermined time by a built-in temperature sensor, and gives a reply that the temperature has risen with its own unique information # S1 and the heat source unit 6 Return wirelessly (see FIG. 21). The heat source unit 6 receives the reply that the temperature has risen from the floor heating remote controller 7-1, and the system number # 1 of the hot water valve 5-1 that sent the control command to the unique information # S1 included in this reply And store it in association with. Thereby, the parent-child relationship between the control part 6-1 and the floor heating remote control 7-1 is prescribed | regulated. Similarly, by sending a control command from the heat source unit 6 to the hot water valve 5-2 by wire and opening the hot water valve 5-2, the parent-child relationship between the control unit 6-2 and the floor heating remote controller 7-2 is established. It is prescribed.

  Here, this wireless communication floor heating system will be compared with the VAV control system shown in FIG. In this case, the hot water valve 5-1 corresponds to the VAV unit 1-1, the control unit 6-1 corresponds to the VAV controller 2-1, and the floor heating remote controller 7-1 corresponds to the wireless sensor 3-1. Further, the hot water valve 5-2 corresponds to the VAV unit 1-2, the control unit 6-2 corresponds to the VAV controller 2-2, and the floor heating remote controller 7-2 corresponds to the wireless sensor 3-2.

  Therefore, when the technology of the wireless communication floor heating system is applied to the VAV control system, as shown in FIG. 22, for the VAV units 1-1 and 1-2 (corresponding to the hot water valves 5-1 and 5-2). A system management controller 8 (corresponding to the heat source unit 6) having a wireless communication function is provided, and the VAV control units 8-1 and 8-2 (corresponding to the control units 6-1 and 6-2) are provided in the system management controller 8. It is conceivable that the VAV control units 8-1 and 8-2 and the VAV units 1-1 and 1-2 are connected by wire.

  However, in such a VAV control system, since the system management controller 8 and the VAV units 1-1 and 1-2 are connected by wire, the system management controller 8 and a VAV installed on the ceiling or the like are used. Wiring work between the units 1-1 and 1-2 is complicated. Further, the number of connectable VAV units 1 (upper limit number) is determined by the number of wired ports of the system management controller 8, and the system management controller 8 greatly increases the number of VAV unit 1 addition requests exceeding the upper limit number. Remodeling is required.

  The present invention has been made to solve such a problem, and the object of the present invention is to easily and reliably define the parent-child relationship between the control controller and the wireless sensor, and to perform wiring work. It is an object of the present invention to provide a radio control system that can easily add control target devices.

  In order to achieve such an object, the first invention (the invention according to claim 1), a control target device, a control controller that controls the operation of the control target device, and a predetermined change that varies depending on the operation of the control target device In a wireless control system including an event as a measurement target and one or more wireless sensors that wirelessly transmit the measurement target data as event data, a control command is sent to the control controller by wireless, and a predetermined command according to the control command is sent After causing the control target device to perform the operation, the parent-child relationship between the wireless sensor and the controller is defined based on the event data transmitted from the wireless sensor, and information on the defined parent-child relationship is controlled wirelessly. It is provided with a parent-child relationship defining means set in the controller.

  According to the present invention, for example, when a control target device is a VAV unit, a control controller is a VAV controller, and a parent-child relationship defining means is a system management controller, a control command is sent from the system management controller to the VAV controller by radio. The VAV unit performs a predetermined operation according to the command (for example, the damper opening degree of the VAV unit is changed from fully closed to fully open). After the operation of the VAV unit, the system management controller defines a parent-child relationship between the wireless sensor and the VAV controller based on event data (for example, temperature data) transmitted from the wireless sensor, and the defined parent-child relationship Information on the relationship is set in the VAV controller wirelessly. For example, when event data is transmitted from a plurality of wireless sensors, the correlation between the change in the event data and the control command sent to the VAV controller is compared, and the wireless sensor having the largest correlation is parent-child with the VAV controller. The relationship is defined, and the system information set in the wireless sensor is set in the VAV controller as information on the parent-child relationship.

  In the present invention, the information related to the parent-child relationship set in the control controller is not limited to the system information, but may be an address assigned for each wireless sensor or unique information determined at the factory shipment stage. Also, the correlation between the change in the event data transmitted from each of the wireless sensors and the control command sent to the control controller is compared, and the parent and child with the control controller for a predetermined number of wireless sensors in descending order of correlation. You may make it prescribe | regulate a relationship (2nd invention (invention which concerns on Claim 2)). In addition, instead of comparing the correlation between the change in event data transmitted from the wireless sensor and the control command sent to the control controller, the control controller for the wireless sensor whose event data has changed the most (reacts most). The parent-child relationship with the control controller may be defined for a predetermined number of wireless sensors in the order in which the event data changes greatly.

Also, system information is stored in each wireless sensor, and the correlation between the change in event data transmitted from each wireless sensor and the control command sent to the control controller is compared, and the wireless having the largest correlation is stored. You may make it prescribe | regulate the parent-child relationship with a control controller about the wireless sensor which has memorize | stored the same system | strain information as a sensor and the said wireless sensor (3rd invention (invention based on Claim 3)).
Further, system information is stored in each wireless sensor, and the average amount of change of event data of the wireless sensor storing the same system information is calculated from the event data transmitted from each wireless sensor. The average change amount of event data of the same system is compared, and the correlation between the average change amount of event data of the sensor group of each same system and the control command sent to the controller is compared. You may make it prescribe | regulate the parent-child relationship with a control controller about each wireless sensor (4th invention (invention based on Claim 4)).

  According to the first invention, after sending a control command to the control controller wirelessly, causing the control target device to perform a predetermined operation according to the control command, the wireless sensor and the wireless sensor are based on the event data transmitted from the wireless sensor. When there is a parent-child relationship defining means that prescribes the parent-child relationship with the control controller and sets information related to the defined parent-child relationship in the control controller wirelessly. However, it is possible to easily and reliably define the parent-child relationship between the control controller and the wireless sensor. Also, for example, when the parent-child relationship defining means is a system management controller, the system management controller and the control controller are connected by radio, so the wiring work between the system management controller and the control controller does not become complicated. Further, it becomes possible to easily add control target devices.

  Further, according to the second invention, the correlation between the change in the event data transmitted from each of the wireless sensors and the control command sent to the control controller is compared, and a predetermined number of wirelesss are ordered in descending order of correlation. By defining the parent-child relationship with the control controller for the sensor, in addition to the effect of the first invention, when control is performed using a plurality of wireless sensors for one control controller, the control controller and their It is possible to shorten the work of defining the parent-child relationship with the wireless sensor.

  Further, according to the third invention, the correlation between the change in event data transmitted from each of the wireless sensors and the control command sent to the control controller is compared, and the wireless sensor having the largest correlation and the wireless sensor By defining the parent-child relationship with the controller for wireless sensors that store the same system information, in addition to the effects of the second invention, wireless sensors having different system information (wireless sensors installed in different areas) It is possible to prevent mistakes that erroneously define a wireless sensor of the same system.

  According to the fourth invention, the average change amount of event data of the wireless sensor storing the same system information is calculated from the event data transmitted from each of the wireless sensors. As a quantity, the correlation between the average change amount of event data of each sensor group of the same system and the control command sent to the controller is compared, and the control controller for each wireless sensor of the sensor group of the same system having the largest correlation In addition to the effects of the third invention, even when it is determined that a wireless sensor having different system information has the largest correlation due to disturbance, the sensor group of the same system By using the average change amount of the event data as an index, the influence can be reduced and more precise parent-child relationship can be defined.

Hereinafter, the present invention will be described in detail with reference to the drawings.

C2 and opening information θ2pv (information indicating the current damper opening of the VAV unit 1-2) are collected as initial information. Further, the unique information # S1, the system information # 1, and the measured value t1pv of the room temperature are collected as initial information from the wireless sensor 3-1, and the unique information # S2, the system information # 2 and the room temperature are collected from the wireless sensor 3-2. The measurement value t2pv is collected as initial information.

  As a result, the system management controller 10 performs temporary wiring by wireless communication with the actual unit (see FIG. 7), and the VAV controller 2-1 as the actual VAV controller 1 and the VAV controller 2-2 as the actual VAV controller 2. The initial information of the VAV controllers 2-1 and 2-2 is stored in the virtual wiring file F1. Further, the wireless sensor 3-1 is the actual temperature sensor 1, the wireless sensor 3-2 is the actual temperature sensor 2, and initial information of the wireless sensors 3-1 and 3-2 is stored in the virtual wiring file F1.

[Monitor of temperature change (system 1): Step 2]
Next, the system management controller 10 sends a control command wirelessly to the VAV controller 2-1 (see FIG. 2), and changes the damper opening of the VAV unit 1-1 from fully closed to fully open. Thereafter, changes in the measured values t1pv and t2pv of the room temperature transmitted from the wireless sensors 3-1 and 3-2, that is, changes in the temperature data transmitted from the wireless sensors 3-1 and 3-2 ( Monitoring of temperature change is started (see FIG. 8).

[Specification of system (system 1): Step 3]
Then, the system management controller 10 specifies the system in which the VAV controller 2-1 is installed from the monitoring result of the change in temperature data from the wireless sensors 3-1 and 3-2. In this case, the system management controller 10 compares the correlation between the change in temperature data from the wireless sensor 3-1, the change in temperature data from the wireless sensor 3-2, and the control command sent to the VAV controller 2-1. (See FIG. 3). Temperature data from the wireless sensor 3-1 having the largest correlation is determined as the control input of the VAV controller 2-1, and the parent-child relationship of the wireless sensor 3-1 with the VAV controller 2-1 is determined. Is specified. That is, the system management controller 10 determines that there is a relationship between the wireless sensor 3-1 and the VAV controller 2-1, and the wireless sensor 3-1 is included in the initial information of the VAV controller 2-1 in the virtual wiring file F1. The system information # 1 set in is written (see FIG. 9).

[Temperature change monitor (system 2): Step 4]
Next, the system management controller 10 sends a control command wirelessly to the VAV controller 2-2 (see FIG. 4), and changes the damper opening degree of the VAV unit 1-2 from fully closed to fully open. Thereafter, monitoring of changes in temperature data (temperature changes) transmitted from the wireless sensors 3-1 and 3-2 is started (see FIG. 10).

[Specification of system (system 2): Step 5]
Then, the system management controller 10 identifies the system in which the VAV controller 2-2 is installed from the monitoring result of the change in temperature data from the wireless sensors 3-1 and 3-2 in the same manner as before (FIG. 5). In this case, the correlation between the change in temperature data from the wireless sensor 3-2 and the control command sent to the VAV controller 2-2 becomes the largest, so that the system management controller 10 can connect the wireless sensor 3-2 and the VAV controller 2 to each other. -2 is determined, and the system information # 2 set in the wireless sensor 3-2 is written in the initial information of the VAV controller 2-2 of the virtual wiring file F1 (see FIG. 11).

[Set specified system information to actual VAV controller: Step 6]
Next, the system management controller 10 extracts the system information # 1 written in the initial information of the VAV controller 2-1 in the virtual wiring file F1 (see FIG. 12), and sends this system information # 1 to the VAV controller 2-1. It transmits by radio (see FIG. 6). Further, the system information # 2 written in the initial information of the VAV controller 2-2 in the virtual wiring file F1 is extracted (see FIG. 12), and this system information # 2 is transmitted to the VAV controller 2-2 by radio (FIG. 6). reference).

  As a result, system information # 1 is set in the VAV controller 2-1, the VAV controller 2-1 and the wireless sensor 3-1 are associated with each other by the same system information # 1, and the VAV controller 2-1 and the wireless sensor 3 are associated with each other. The actual parent-child relationship is established with -1. Further, system information # 2 is set in the VAV controller 2-2, the VAV controller 2-2 and the wireless sensor 3-2 are associated with each other by the same system information # 2, and the VAV controller 2-2 and the wireless sensor 3- The actual parent-child relationship is established between the two.

[Create system point configuration file: Step 7]
The system management controller 10 belongs to the systems 1 and 2 based on the initial information of the VAV controllers 2-1 and 2-2 and the initial information of the wireless sensors 3-1 and 3-2 written in the virtual wiring file F1. A system point configuration file F2 (see FIG. 6) indicating the configuration of the device is created.

  In this VAV control system, the parent-child relationship between the VAV controller 3 and the wireless sensor 3 is automatically defined only by sending a command from the central monitoring panel 9 to the system management controller 10. Therefore, even when the VAV controller 2 is installed behind the ceiling or the like, the parent-child relationship between the VAV controller 2 and the wireless sensor 3 can be defined easily and reliably.

  Further, in this VAV control system, since transmission / reception of information between the system management controller 10 and the VAV controller 2 is performed wirelessly, it is not necessary to perform wiring work between the system management controller 10 and the VAV controller 2. Further, it is possible to meet the request for increasing the number of stages of the VAV unit 1 without modifying the system management controller 10.

  Further, in this VAV control system, the system management controller 10 grasps the VAV controller 2 that is wirelessly connected, so by controlling the order in which the VAV unit 1 is moved, the VAV controller 2 and the wireless sensor of each system are controlled. 3 can be completely automated.

  Further, in this VAV control system, the central monitoring panel 9 grasps the connected system management controller 10, so that the system identification work for the entire building can be performed by setting the above sequence in advance for each system management controller 10. It can be fully automated.

  In the first embodiment, for the temperature data from the wireless sensor 3, the correlation between the change in the temperature data and the control command sent to the VAV controller 2 is compared. The parent-child relationship with the VAV controller 2 may be defined for the wireless sensor 3 with the largest change (the largest reaction).

  In the first embodiment, system information is set in the wireless sensor 3, and this system information is set in the VAV controller 2 that defines the parent-child relationship. However, an address is assigned to each wireless sensor 3. This address may be set in the VAV controller 2 that defines the parent-child relationship, or the unique information defined in the wireless sensor 3 at the factory shipment stage may be set in the VAV controller 2 that defines the parent-child relationship. Good.

[Embodiment 2]
In the first embodiment, a simple example in which only one wireless sensor 3 is installed in each of the systems 1 and 2 is shown. However, a plurality of wireless sensors 3 may be installed in the systems 1 and 2. For example, as shown in FIG. 13, it is assumed that wireless sensors 3-1 to 3-4 are installed in the system 1 and wireless sensors 3-5 to 3-7 are installed in the system 2. Further, it is assumed that the system information # 1 is already set in the wireless sensors 3-1 to 3-4, and the system information # 2 is already set in the wireless sensors 3-5 to 3-7.

  In the second embodiment, for example, a control command from fully closed to fully opened is sent from the system management controller 10 to the VAV controller 2-1, and between this control command and a change in temperature data from the wireless sensor 3-1. When a large correlation is recognized, the system information # 1 set in the wireless sensor 3-1 is set in the VAV controller 2-1.

  In this case, since the same system information # 1 is set not only for the wireless sensor 3-1, but also for the wireless sensors 3-2 to 3-4, the VAV controller 2-1 and the wireless sensors 3-2 to 3-4 are set. The parent-child relationship will also be defined between the two.

  As described above, in the second embodiment, when the room temperature is controlled using a plurality of wireless sensors 3 for the VAV controller 2, the parent and child are chained between the VAV controller 2 and the wireless sensor 3. The relationship is defined, and the regulation work for the parent-child relationship can be shortened.

[Embodiment 3]
In the second embodiment, for example, when the wireless sensor 3-5 reacts greatly due to some disturbance when a control command is sent to the VAV controller 2-1 to operate the VAV unit 1-1, the wireless on the system 1 side There is a possibility that the parent-child relationship with the VAV controller 2-1 may be defined for the wireless sensors 3-5 to 3-7 on the system 2 side, not the sensors 3-1 to 3-4.

  Therefore, in the third embodiment, for the temperature data transmitted from each of the wireless sensors 3, the average of the amount of change in the temperature data of the wireless sensors 3-1 to 3-4 having the system information # 1 is calculated. The average change amount of the temperature data of the group 2, the average change amount of the temperature data of the wireless sensors 3-5 to 3-7 having the system information # 2 is set as the average change amount of the temperature data of the sensor group of the system 2, and this system The correlation between the average change amount of the temperature data of the sensor group 1 and the average change amount of the temperature data of the sensor group of the system 2 and the control command sent to the VAV controller 2-1 is compared, and the same system having the largest correlation The parent-child relationship with the VAV controller 2-1 is defined for each wireless sensor in the sensor group.

  In the example of FIG. 13, when the control command is sent to the VAV controller 2-1 to operate the VAV unit 1-1, the average change amount of the temperature data of the sensor group of the system 1 becomes large. Therefore, the sensor group of the system 1 is specified as the sensor group of the same system having the largest correlation with the control command, and the wireless sensors 3-1 to 3-4 of the sensor group of the system 1 are connected to the VAV controller 2-1. The parent-child relationship is defined.

  As a result, system information # 1 of the sensor group of system 1 is set in the VAV controller 2-1, and an actual parent-child relationship is established between the VAV controller 2-1 and the wireless sensors 3-1 to 3-4. Even if it is determined that the wireless sensor 3 (3-5, 3-6, 3-7) having the system information # 2 has the largest correlation due to the disturbance, the influence is reduced and more accurate It is possible to define parent-child relationships.

[Embodiment 4]
In the first embodiment, the room 4 is divided into a system 1 and a system 2, the VAV unit 1-1 and the VAV controller 2-1 for the system 1, and the VAV unit 1-2 and the VAV controller 2 for the system 2. -2 is provided, for example, as shown in FIG. 14, the room 4 is divided into a system 1 to a system 6, and a VAV unit 1-1 and a VAV controller 2-1 are connected to the systems 1 to 3 in a system 4 ˜6 may be provided with a VAV unit 1-2 and a VAV controller 2-2.

  In the fourth embodiment, the system management controller 10 compares the correlation between the change in temperature data transmitted from each of the wireless sensors 3 and the control command sent to the VAV controller 2, and the correlation is large. A parent-child relationship with the VAV controller 2 is specified for a predetermined number of wireless sensors 3 in order.

  For example, the system management controller 10 has four wireless sensors 3 that define a parent-child relationship with the VAV controller 2-1, and three wireless sensors 3 that define a parent-child relationship with the VAV controller 2-2. Register as a stand. Also, system information # 1 is stored in the wireless sensor 3-1, system information # 2 is stored in the wireless sensor 3-2, system information # 3 is stored in the wireless sensor 3-3, system information # 1 is stored in the wireless sensor 3-4, Assume that system information # 4 is already set in the wireless sensor 3-5, system information # 5 is already set in the wireless sensor 3-6, and system information # 6 is already set in the wireless sensor 3-7.

  In this case, the system management controller 10 sends a control command to the VAV controller 2-1, changes the damper opening of the VAV unit 1 from fully closed to fully open, and then transmits the temperature data transmitted from each wireless sensor 3. Monitor changes. Here, the correlation between the control command sent to the VAV controller 2-1 and the change in temperature data from the wireless sensor 3 increases in the order of the wireless sensors 3-1, 3-2, 3-3, 3-4. Then, the system management controller 10 defines the parent-child relationship with the VAV controller 2-1 for the four wireless sensors 3-1, 3-2, 3-3, 3-4. As a result, the system information # 1 held by the wireless sensors 3-1 and 3-4, the system information # 2 held by the wireless sensor 3-2, and the system information # 3 held by the wireless sensor 3-3 are set in the VAV controller 2-1. Thus, an actual parent-child relationship is established between the VAV controller 2-1 and the wireless sensors 3-1 to 3-4.

  Further, the system management controller 10 sends a control command to the VAV controller 2-2 to change the damper opening degree of the VAV unit 1 from fully closed to fully open, and then changes the temperature data transmitted from each wireless sensor 3. To monitor. Here, if the correlation between the control command sent to the VAV controller 2-2 and the change in temperature data from the wireless sensor 3 is larger in the order of the wireless sensors 3-5, 3-6, 3-6, The management controller 10 defines a parent-child relationship with the VAV controller 2-2 for the three wireless sensors 3-5, 3-6, and 3-7. As a result, the system information # 1 held by the wireless sensors 3-1 and 3-4, the system information # 2 held by the wireless sensor 3-2, and the system information # 3 held by the wireless sensor 3-3 are set in the VAV controller 2-1. Thus, an actual parent-child relationship is established between the VAV controller 2-1 and the wireless sensors 3-1 to 3-4.

[Embodiment 5]
In the fourth embodiment described above, the system information is set for the wireless sensors 3-1 to 3-7, but an arbitrary address may be assigned to the wireless sensors 3-1 to 3-7. . In this case, for example, the system management controller 10 indicates that the correlation between the control command sent to the VAV controller 2-1 and the change in the temperature data from the wireless sensor 3 is wireless sensors 3-1, 3-2, 3-3. If it is determined to be larger in the order of 3-4, the addresses assigned to the wireless sensors 3-1, 3-2, 3-3, 3-4 are set in the VAV controller 2-1.

  In the fourth embodiment, instead of assigning addresses to the wireless sensors 3-1 to 3-7, unique information set at the factory shipment stage is used for the wireless sensors 3-1 to 3-7. The unique information may be set in the VAV controller 2 in which the parent-child relationship is defined.

  In the fourth embodiment and the fifth embodiment, when the heat insulation by the walls partitioning the systems 1 to 3 and the systems 4 to 6 is insufficient, the parent-child relationship between the wireless sensor 3 and the VAV controller 2 is incorrect. May be specified. For example, when the wireless sensor 3-5 reacts greatly to a control command to the VAV controller 2-1, a parent-child relationship with the VAV controller 2-1 may be defined for the wireless sensor 3-5.

  In order to eliminate such a fear, as shown in the second embodiment, the same system information is set in all the wireless sensors 3 installed in the systems 1 to 3, and the systems 3 to 4 are set. It is better to set the same system information for all installed wireless sensors 3. In this way, for example, even if the wireless sensor 3-5 reacts greatly to the control command to the VAV controller 2-1, if the wireless sensor 3-1 shows the maximum response (maximum correlation), the wireless sensor 3-5 The system information set in 3-1 is set in the VAV controller 2-1, and there is no problem that the parent-child relationship is defined between the wireless sensor 3-5 and the VAV controller 2-1. .

[Embodiment 6]
In the first embodiment described above, the central monitoring panel 9 gives a command to start the regulation of the parent-child relationship to the system management controller 10, but as shown in FIG. 15, the temperature sensor and the temperature controller are combined. The remote controller 11 may be installed in the room 4 as a wireless sensor, and a parent-child relationship may be defined by giving a measured value and a set value of the room temperature from the remote controller 11.

  In the sixth embodiment, for example, when the system management controller 10 receives the measured value t2pv and the set value t2sp of the room temperature together with information indicating that the parent-child relationship is specified from the remote controller 11-2, A control command is sent to the VAV controller 2-1 so that t2pv = t2sp, and the damper opening degree of the VAV unit 1-1 is controlled. Then, it is checked whether or not t2pv = t2sp is satisfied within a predetermined time T. If t2pv = t2sp is not satisfied within the predetermined time T, a control command is sent to the VAV controller 2-2 so that t2pv = t2sp is satisfied. The damper opening degree of the unit 1-2 is controlled.

  In this example, in the control of the damper opening degree of the VAV unit 1-1, t2pv = t2sp does not occur within the predetermined time T. Therefore, in this case, the system management controller 10 sends a control command to the VAV controller 2-2 so that t2pv = t2sp, and controls the damper opening degree of the VAV unit 1-2. When it is confirmed that t2pv = t2sp is satisfied within the predetermined time T, the system information # 2 set in the remote controller 11-2 is set in the VAV controller 2-2.

  Although the first to sixth embodiments have been described by taking the VAV control system as an example, the present invention is not limited to application to the VAV control system, and the control target device and the operation of the control target device are described. Any system can be applied in the same manner as long as it is a wireless control system including a control controller to be controlled and a wireless sensor that measures a predetermined event that changes depending on the operation of the control target device. .
