When the current number of persons ≧ the previous number in step 35, it is judged whether or not this change corresponds to the case where the previous number is 0 and the current number is 1 (step 38). Control is performed (step 39). This is a case where one person has entered the zone where there was no one before. If the case of step 38 is not applicable,
Judge whether the current number of people is more than the predetermined maximum number (see 4
0), if applicable, control to increase the device output is performed (41), and if not applicable, the device is not controlled and the process ends.

The above steps 32 to 41 are executed for each zone in each cycle. Further, when each process of power-on (39 in FIG. 3), power-off (same as 34), device output up (same as 41) and device output down (same as 37) is executed, a command instructing each control is issued. It is created and output to the interface (28 in FIG. 2).

By controlling in this way, when one person enters the zone, the power of various devices is turned on, and when the number of people goes out of the zone, when the number of people becomes 0, the person is monitored for a certain time by the timer monitoring. If not present, power can be turned off. Also, when the number of people in the zone exceeds a certain number, the work environment can be managed by performing operations such as increasing the luminous intensity of the lighting and adjusting the temperature of the air conditioning.
