The power demand control system 300 controls the device to be shut off without registering it by interlocking with the entrance / exit management system.

  FIG. 2 is a diagram illustrating the relationship among the elements in FIG.

As shown in FIG. 2, a plurality of areas 400 exist in a building that is managed by the power demand control system 300, and a door 500 for entrance / exit control is arranged in each area 400.
The door 500 is, for example, a traffic lane type flapper gate, a door provided with an electric lock, an automatic door, or the like.
The entry-side card reader 102 is arranged outside the area 400, and a passerby who wants to enter the area 400 reads, for example, the authentication information of the passerby stored in the card by holding the IC card. The transmitted authentication information is transmitted to the entrance / exit controller device 101.
Further, the exit card reader 103 is arranged in the area 400, and a passerby who is going to exit the area 400 reads the authentication information of the passerby stored in the card by holding the IC card, for example. The read authentication information is transmitted to the entrance / exit controller device 101.
The entrance / exit controller device 101 collates the authentication information from the entry card reader 102 or the exit card reader 103 with the collation information, and authenticates whether the passer-by may pass through the door 500. When it is possible to pass, the door 500 is unlocked.
In this way, the entrance / exit controller device 101 monitors the entrance / exit status of people for each area, and grasps the number of people in each area through the authentication process. In addition, each area 400 can be divided into a plurality of areas, and a user who uses each area is designated (for example, an office where a seat is assigned to each user, etc., such an area is used) The entrance / exit controller device 101 monitors the entrance / exit status for each user to determine whether each user is located in the user designated area (person entry / exit information). .
Then, the entrance / exit controller device 101 transmits the presence / absence information for each area and the person's entrance / exit information to the demand monitoring control device 201.
The entrance / exit controller device 101 is an example of an area entrance / exit monitoring unit.

In each area 400, an air conditioning system 202 and a plurality of lighting devices 203a that are part of the lighting system 203 are arranged. Each lighting device 203a is connected to a lighting device control device 203b.

The demand monitoring control apparatus 201 is an example of a device management unit.
For example, the demand monitoring control device 201 stops the operation of the devices arranged in the area determined to be unattended by the entrance / exit controller device 101. Moreover, the operation of the apparatus arrange | positioned in the area where the number of people located is judged to be below a specific number by the entrance / exit controller apparatus 101 is controlled, and the power consumption in the said area is reduced. Specifically, the demand monitoring control device 201 is arranged in the vicinity of a user's area that is not in a room in a user-designated area with a small number of people based on information on people entering / leaving from the entrance / exit controller device 101. The power consumption in the area is reduced by controlling the operation of the connected equipment.

  Next, a configuration example of the entrance / exit controller device 101 will be described with reference to FIG.

Also, the analysis processing unit 207 can know the number of users in each area by using the user IDs of the people in each area notified from the entrance / exit controller device 101, and the number of people in the area is small. Controls such as stopping the devices in the area or shifting to a mode with less power consumption can be performed.

The reduction target device information storage unit 211 stores reduction target device information.
The reduction target device information is information indicating an ID of a device that is predetermined as an operation stop or adjustment target.
The reduction target device is a low priority device.

  Next, an operation example of the power demand control system 300 according to the present embodiment will be described with reference to the flowchart of FIG.

First, the communication unit 108 of the entrance / exit controller device 101 transmits the presence / absence information for each area and the person entry / exit information, and the communication unit 205 of the demand monitoring control device 201 receives this information (S801).
Transmission / reception of the presence / absence information and the person's entry / exit information for each area is periodically performed.
In the following description, it is assumed that the occupancy information illustrated in FIG. 6 is transmitted from the communication unit 108 to the communication unit 205.

Next, in the demand monitoring control apparatus 201, the analysis processing unit 207 determines whether or not the demand prediction value calculated by the demand prediction unit 206 exceeds the target value (S802), and the demand prediction value does not exceed the target value. In the case (NO in S802), the process returns to S801.
On the other hand, when the demand predicted value exceeds the target value (YES in S802), the analysis processing unit 207 investigates the occupancy information and searches for an area where the user is absent (S803).

If there is an absent area (YES in S804), the analysis processing unit 207 next determines whether the area where the user is absent is an operation continuation area (S805).
If the absent area is not an operation continuation area and the operation of the device can be stopped (YES in S805), the analysis processing unit 207 refers to the region device information and targets the device interface unit 208 to the target. The device interface unit 208 controls the target device and turns off the power of the device (S806).
On the other hand, when the area where the user is absent is the operation continuation area and the operation of the device cannot be stopped (NO in S805), the process returns to S802.

If there is no room in which the user is absent in S804, the analysis processing unit 207 next checks the occupancy information and searches for an area where the number of users is equal to or less than the predetermined number (S807).
When there is an area where the number of users is equal to or less than the predetermined number (YES in S808), the analysis processing unit 207 refers to the occupancy information and the user area information, and the area where the user is not present Alternatively, an area where the number of users who are present is equal to or less than the predetermined number is searched (S809).
If there is such a region (YES in S810), the analysis processing unit 207 refers to the region device information, notifies the device interface unit 208 of the target device ID, and the device interface unit 208 targets. And control the operation of the device (S811). More specifically, the device interface unit 208 performs control for reducing power consumption such as reducing the illuminance of the illumination around the area, changing the set temperature of the air conditioning, and reducing the air volume.
On the other hand, if there is no corresponding area in S810, the process returns to S807.

In S808, if there is no corresponding area, the analysis processing unit 207 determines again whether the demand prediction value exceeds the target value (S812), and the demand prediction value exceeds the target value. In this case (YES in S812), normal demand control is performed (S813). Specifically, the analysis processing unit 207 notifies the device interface unit 208 of the device ID of the reduction target device indicated in the reduction target device information, and the device interface unit 208 controls the target device, Turn off the device.
On the other hand, in S812, when the demand prediction value does not exceed the target value, the process returns to S801.

  In the flow of FIG. 8, when the demand prediction value exceeds the target value (YES in S802), the area where the user is absent is searched (S803), but the user is absent first. You may make it search an area and turn off the air conditioner and illumination of the area. Thereby, there is an effect that wasteful power consumption due to forgetting to turn off can be suppressed.

  Thus, according to this embodiment, in order to stop the operation of the device in the area where the user is absent, unlike the case where the target device to be stopped is set in advance based on the use frequency, If a person is present in a low area, the operation of the equipment in the area will not be forcibly stopped. On the other hand, if the frequently used area is unattended, the equipment in the area Can be stopped and efficient power control can be performed.

Further, in the present embodiment, when there are areas where the number of users is less than a predetermined number, the area of the person who is not present is determined, the set temperature of the air conditioning around the area is changed, and the air volume is changed. Reduce the aperture and illumination intensity.
As described above, since the operation of the device is limited to a part of the area, fine energy saving control is possible, and an energy saving effect can be obtained.

  As described above, in the present embodiment, the power demand control system has been described in which a room in which a person is absent is identified and lighting and air conditioning in the room are shut off.

  In this embodiment, even when a person is present in the room, the temperature of the air conditioning around the desk of a person who is not present is changed, the air volume is reduced, the temperature is increased in summer, and the temperature is increased in winter. A power demand control system has been described that lowers the illuminance of the lighting around the desk area of people who are not present.
