The remote server is connected with the intelligent gateway through the Internet; the remote server is used for receiving, storing and processing the data of each intelligent terminal transmitted by the intelligent gateway and can control each intelligent terminal after processing. In consideration of the cost and the safety of the remote server, the remote server preferably adopts an internet of things cloud platform, and the applicant preferably selects a doodling internet of things cloud platform in the application.

The intelligent gateway is independently connected with each intelligent terminal through an Internet of things transmission module arranged on each intelligent terminal; the intelligent terminal comprises a lighting switch, a socket, an entrance guard, a temperature and humidity sensor, a door pusher, a curtain pusher, an air conditioner human motion sensor and a valve; the human motion sensors are respectively arranged at the door entrance, the station and the indoor ceiling and are used for monitoring the walking of the door, the station and indoor personnel. And the mode of independently connecting with the intelligent gateway is adopted, so that the remote server can conveniently and accurately control the intelligent terminal.

The transmission module of the Internet of things of the lighting switch, the socket, the entrance guard, the human body motion sensor, the temperature and humidity sensor, the door pusher, the window pusher and the valve adopts a zigbee communication module; and the transmission module of the Internet of things of the air conditioner adopts a WiFi communication module. By adopting the mode, the Zigbee is mainly used as a short-distance and low-power consumption wireless communication protocol, the biggest advantage is that a device network can be automatically formed to link the direct data transmission of each device, but a central node is needed in the ad hoc network to manage the whole Zigbee network, namely, a component similar to a router is needed in the Zigbee device network to connect the devices together, so that the linkage effect among the Zigbee devices is realized. This additional "router" component is said to be an intelligent gateway. However, most Zigbee devices are not provided with a gateway, so that a single Zigbee device cannot be directly controlled by a client basically, and such an intelligent gateway is required to be used as a connection hub between each intelligent terminal and the client.
