Taking a larger office as an example, the third preset value may be set to 180, the 3D sensor may be set at the entrance of the office, and every time a target object comes in, the counter is incremented by 1, when it is detected that the number of the target objects in the office is 50 (less than 180), a power-on control signal of part of the controlled devices is output to the power control module, the power control module provides power to part of the controlled devices, and the part of the controlled devices near the target object is turned on, for example, 1 air conditioner and 15 lamps are turned on; when the number of the target objects in the office is detected to be 181 (larger than 180), power-on control signals of all the controlled devices are output to the power control module, the power control module supplies power to all the controlled devices, and all the controlled devices are turned on, for example, 4 air conditioners and 60 lamps are turned on. And when the target objects are detected to leave the office, the counter is decremented by 1 every time one target object is removed, and if the number of the target objects is detected to be 0, a power supply cut-off control signal is output to the power supply control module, and the power supplies of all the controlled equipment are cut off. When the number of the detected target objects is equal to the third preset value, whether part of the controlled devices in the control area are started or all the controlled devices are started is determined, and the method is not limited in this application. The third preset value, some of the controlled devices and all of the controlled devices may be set according to requirements, and the counting method may also be set as other methods, which are not limited in this application.
