In this paper,an intelligent power management system based on WiFi interaction was studied,which can automatically judge whether there is anyone in the room and intelligently control different power sockets according to the scene.The system consists of wireless routers Honor Cube,custom-designed power sockets and mobile phones without additional apps.Wireless router is the monitoring and control center of the whole system.Through third-party apps,it can monitor WiFi connection state of cell phone in real time,judge whether there is someone indoor through WiFi connection status,send the human or unmanned control signals to power sockets.The power sockets receive the control signals from the Honor Cube and control the power sources of different types of electrical equipment.The system has the advantages of intelligent interaction and dynamic adjustment.The experimental results show that the system applies to home or office room,not only saving electricity,but also preventing the risk of personal privacy leakage.
