(Applicable scene)
Next, an application scene of the control system 1 of the present embodiment will be described.

  FIG. 2 is a plan view illustrating an example of a store in which the air conditioning facility 20, the cooling facility 30, and the lighting fixture 40 are installed in the present embodiment.

  As shown in FIG. 2, a plurality of air conditioning facilities 20a to 20f, a plurality of cooling facilities 30a to 30d, and lighting fixtures 40a to 40j are installed in the store.

  In the control system 1 of the present embodiment, for example, after the store is closed, when the air conditioner 20a is in operation without being stopped, information indicating that it is in an operating state is included in the equipment state information transmitted to the control device 10 at a predetermined cycle. included. Thereby, the control apparatus 10 detects that the equipment state of the air conditioning equipment 20a is an operation state.

  Next, the control apparatus 10 specifies that the lighting fixture 40 located closest to the air conditioning equipment 20a is the lighting fixture 40c.

  And the control apparatus 10 performs dimming control with respect to the specified lighting fixture 40c. Here, the dimming control to be executed is, for example, control to increase (brighten) the dimming level (brightness). Further, the dimming control to be executed is controlled so as to continue the dimming even when the manual power switch of the lighting fixture 40 is turned off.

  Thereby, for example, the employee easily grasps the brightest lighting fixture 40c on the floor of the store, and the air conditioner 20a located closest to the lighting fixture 40c is continuously operated (not stopped). I can understand that. Furthermore, even if the employee turns off the manual power switch of the luminaire 40, the dimming of the luminaire 40c is continued. Therefore, the dimming continues by turning off the luminaire 40 on the floor. It is possible to easily grasp the lighting fixture 40a.

  Similarly, in the case of the cooling facility 30, for example, after the store is closed, when the cooling facility 30 a is not covered with the night cover, the facility state information transmitted to the control device 10 at a predetermined cycle includes information indicating the uncovered state. It is. Thereby, the control apparatus 10 detects that the equipment state of the cooling equipment 30a is an uncovered state.

  Next, the control apparatus 10 specifies that the lighting fixture 40 located closest to the cooling facility 30a is the lighting fixture 40a.

  And the control apparatus 10 performs dimming control with respect to the specified lighting fixture 40a.

  Thereby, for example, the employee easily grasps the brightest lighting fixture 40a on the floor of the store, and the night cover is not attached to the cooling facility 30a located closest to the lighting fixture 40a. I can understand that.

(Functional configuration)
The functional blocks provided in the control device 10 of this embodiment will be described. FIG. 3 is a functional block diagram of the control device 10 of the present embodiment.

  As illustrated in FIG. 3, the control device 10 includes an equipment state acquisition unit 101, a control unit 102, a management unit 103, and a position information storage unit 104.

  The equipment state acquisition unit 101 acquires equipment state information of the air conditioning equipment 20 and the cooling equipment 30 provided in the store. The equipment state information is transmitted from the air conditioning equipment 20 and the cooling equipment 30 to the control device 10 at a predetermined cycle. The equipment state acquisition unit 101 determines whether or not the equipment state included in the received equipment state information is the equipment state. Here, the equipment state is an operating state of the air conditioning equipment 20 and an uncovered state of the cooling equipment 30. And when it determines with the equipment state acquisition part 101 being a predetermined | prescribed state, it notifies the management part 103 of equipment ID contained in equipment state information. The equipment state acquisition unit 101 may periodically poll the equipment provided in the store to acquire the equipment state.

  The control unit 102 performs dimming control of the lighting fixture 40 based on a notification from the management unit 103 described later. Note that the dimming control includes changing the dimming level of the lighting fixture 40 and controlling lighting / extinguishing.

  The management unit 103 manages position information of the air conditioning equipment 20, the cooling equipment 30, and the lighting fixtures 40 installed in the store using the position information storage unit 104.

  As illustrated in FIG. 4, the position information storage unit 104 stores position information for each equipment ID. The equipment ID is identification information for identifying the air conditioning equipment 20, the cooling equipment 30, and the lighting fixture 40 installed in the store. The location information includes a store name, a floor, and an area. The area is a section obtained by dividing the floor by a predetermined size. The size of the area is a size capable of distinguishing the positions of the air conditioning equipment 20, the cooling equipment 30, and the lighting fixture 40. Different equipment may be installed in the same area. Note that latitude and longitude may be used instead of the area. In this case, the latitude and longitude are set in advance by an administrator of the control system 1 or specified by an indoor positioning technique using IMES (Indoor Messaging System) and ZigBee. The position information storage unit 104 is a memory facility or a hard disk provided in the control device 10. However, the information stored in the location information storage unit 104 may be stored in a cloud server or an external recording medium that can be connected via a network.

  When the management unit 103 receives the notification of the facility ID of the air conditioning facility 20 or the cooling facility 30 from the facility state acquisition unit 101, the management unit 103 identifies the luminaire 40 that is located closest to the facility corresponding to the facility ID. The management unit 103 notifies the control unit 102 of the specified lighting fixture 40.

(Processing procedure)
FIG. 5 is a flowchart showing a processing procedure of the control system 1 in the present embodiment.

  In step S101, the equipment state acquisition unit 101 of the control device 10 acquires the equipment state included in the equipment state information from the equipment provided in the store. The equipment state information includes the equipment ID.

  In step S102, the equipment state acquisition unit 101 determines whether or not the acquired equipment state is a predetermined equipment state (an operating state of the air conditioning equipment 20 or an uncovered state of the cooling equipment 30).

  If the acquired equipment state is not the predetermined equipment state (NO in step S102), the process ends.

  On the other hand, when the acquired equipment state is the equipment state (YES in step S102), the equipment state acquisition unit 101 notifies the management unit 103 of the equipment ID included in the equipment state information, and the process of step S103 is executed. The

  In step S <b> 103, the management unit 103 refers to the position information storage unit 104, and specifies a lighting fixture that is closest to the facility whose facility state is acquired (the facility corresponding to the notified facility ID). The management unit 103 notifies the control unit 102 of the specified lighting fixture 40 (equipment ID of the lighting fixture 40).

  Here, the specific example of the procedure which specifies the lighting fixture 40 located nearest is shown below. For example, when the location information is the example shown in FIG. 4 and the equipment ID included in the equipment status information is “air conditioning equipment A”, the location information of the equipment ID “air conditioning equipment A” is “store A, second floor, Area A1 ". Next, the position information that is closest to the position information “store A, second floor, area A1” of the facility ID “air conditioner A” is searched from the position information storage unit 104. As a result of the search, the equipment ID “lighting fixture A” of the same location information “store A, second floor, area A1” as the equipment ID “air conditioning equipment A” is specified as the lighting fixture 40 located closest.

  Similarly, when the equipment ID included in the equipment state information is “cooling equipment A”, for example, the position information of the equipment ID “cooling equipment A” is “store A, second floor, area B1”. Next, the position information that is closest to the position information “store A, second floor, area B1” of the facility ID “cooling facility A” is searched from the position information storage unit 104. As a result of the search, the equipment ID “lighting fixture C” of the location information “store A, second floor, area B2” located closest to the equipment ID “cooling equipment A” is identified as the lighting equipment 40 located closest. The

  In step S <b> 104, the control unit 102 performs dimming control on the specified lighting fixture 40.

  As described above, according to the control system 1 in the present embodiment, the control device 10 has the lighting located closest to the air conditioning equipment 20 whose equipment state is the operating state and the cooling equipment 30 whose equipment state is the uncovered state. The dimming of the instrument 40 can be controlled.

  Thereby, for example, the employee can find the luminaire 40 that is brighter and more dimmed at a glance among the luminaires 40 that are provided in large stores especially on the floor. And it can grasp | ascertain easily the state where the air-conditioning equipment 20 located nearest to the lighting fixture 40a adjusted more brightly remains, or the cooling equipment 30a is not covered with the night cover. Therefore, useless power consumption by facilities provided in the store after the store is closed can be suppressed.

  Furthermore, dimming of the lighting fixture 40 controlled by the control device 10 in the present embodiment can be continued even when the power of the lighting fixture 40 is off.

  Thereby, for example, if an employee operates a manual power switch of the lighting fixture 40 and turns off all the lighting fixtures 40 on the store floor, the lighting fixture 40 in which the lighting fixture 40 continues to be lit can be easily viewed at a glance. Can be confirmed.

  In the present embodiment, dimming control of the luminaire 40 that is executed based on the equipment state may be executed in a predetermined time zone.

  Thereby, the dimming of the lighting fixture 40 based on the equipment state is performed during the time when the store is closed, that is, the time when the air conditioning equipment 20 is normally stopped and the time when the cooling equipment 30 is covered with the night cover. Control can be executed. In other words, it is possible not to affect the dimming of the lighting device 40 when the store is opened.

  In the present embodiment, an example has been shown in which the dimming level is increased (brightened) as the dimming control of the luminaire 40 executed based on the equipment state. However, the dimming control lowers the dimming level (dims), for example. It may be made to blink or blink.

[Modification of this embodiment]
In the modification of this embodiment, the dimming control content performed based on an equipment state is changed.

  FIG. 6 is a flowchart showing a processing procedure of the control system 1 in a modification of the present embodiment.

  In step S201, the equipment state acquisition unit 101 of the control device 10 acquires the equipment state included in the equipment state information from the equipment provided in the store.

  In step S202, the equipment state acquisition unit 101 determines whether or not the acquired equipment state is an equipment state. In the modification, the equipment state is, for example, during operation, during power suppression control, an uncovered state, and a failure. During power suppression control, for example, is a state in which control for suppressing power consumption of equipment by demand control is being executed. The equipment state can be arbitrarily set and changed by an administrator of the control system 1 or the like, for example.

  Here, when the acquired equipment state is not the equipment state (NO in step S202), the process ends.

  On the other hand, when the acquired equipment state is the equipment state (YES in step S202), the equipment state acquisition unit 101 notifies the management unit 103 of the equipment ID included in the equipment state information, and the process of step S203 is executed. The

  In step S <b> 203, the management unit 103 refers to the position information storage unit 104, and identifies the lighting fixture that is closest to the facility whose facility state is acquired (the facility corresponding to the notified facility ID).

  In step S <b> 204, the management unit 103 determines the dimming control content for the specified lighting fixture 40. Here, the management unit 103 refers to the dimming control content table shown in FIG. 7 in order to determine the dimming control content. As shown in FIG. 7, the dimming control content table includes dimming control content for each equipment state. Based on the example of FIG. 7, when the acquired equipment state is “during power suppression control”, the dimming control content for the lighting fixture 40 is “low dimming level”. The dimming control content table is stored in a memory facility, a hard disk, a cloud server connectable via a network, or an external recording medium provided in the control device 10.

  The management unit 103 notifies the control unit 102 of the specified lighting fixture 40 and the dimming control content.

  In step S <b> 205, the control unit 102 performs dimming control based on the determined dimming control content for the specified lighting fixture 40.

  According to the above procedure, the control system 1 in the modification can determine the dimming control content based on the equipment state.

  Thereby, for example, when the facility is under power suppression control, the illumination is dimmed, and when the facility is out of order, the illumination can be controlled to blink. In this way, for example, an employee of the store can easily grasp the equipment state of the facility according to the dimming control content.
