These techniques are mainly used for moving object detection and perception, and belong to "dynamic" perception techniques. In the application of intelligent home, the working state of the electrical equipment is remotely controlled by using wifi and a mobile phone signal, and the intelligent home remote control system belongs to a passive answer control mode. The active response type control system does not need human intervention, but performs corresponding real-time control according to the environment detection result of the sensor.
Through the above analysis, the problems and defects of the prior art are as follows:
(1) in the prior art, in an intelligent home control system, the state of electrical equipment cannot be automatically controlled, and the automatic and intelligent control effects are poor due to the fact that presetting or remote manual remote control is required.
