As one group.

Next, the time of the delay sensor used when finally leaving the building 3 is set, and this is set to the receiver 2
1 (S102). The receiver 21 then determines whether sensor data has been received from the sensor unit 11 (S103). Here, when sensor data is input from the sensor means 11 to the receiver 21 (S10
3; YES), a reception process is executed for each sensor unit 11 (S104). In this step (S104),
The number of persons is checked from the data detected by the sensor means 11. Note that the sensor data output from the sensor unit 11 is data that has been captured and image-processed by the sensor unit 11 as described above.

Next, the receiver 21 checks the group of the sensor means 11 (S105).

An entry / exit display process for displaying the state of the detected object entering / exiting from 48 on the monitor 23 is executed, and a control process for controlling various devices in the room from the information is also executed.

As the control processing, for example, it is conceivable to turn on the indoor lighting in the case of entering control, to turn off the lighting in the case of exit control, and to increase the sensitivity of the fire sensor.

The entry / exit display processing is performed, for example, as follows. That is, the first management unit 211 of the receiver 21 determines whether or not a detected object is present in the storage area corresponding to the display blocks 225 to 230 based on the data from the sensor unit 11, and ~ 2
When it is determined that the detected object exists in the storage area corresponding to 30, for example, logic “1” is arranged in the storage area, and based on the direction data of the detected object from the sensor means 11, the blocks 225 to 225 are detected. The moving direction of the detection object is determined and stored in the directional storage area corresponding to 230.
