Switch cabinet temperature monitoring system based on wireless network

The utility model relates to a switch cabinet temperature monitoring system based on the wireless network. The switch cabinet temperature monitoring system comprises a wireless temperature sensor unit, a temperature monitoring unit and an upper computer, wherein the wireless temperature sensor unit and the temperature monitoring unit are in wireless communication, and the temperature monitoring unit is connected with the upper computer via a networking communication interface circuit. A wireless temperature sensor adopted by the system has a small size and can be pasted on a heating point. The switch cabinet temperature monitoring system is low in energy consumption and is powered by batteries, thereby avoiding power problems that are caused under passive conditions. In addition, the system is capable of timely and accurately reflecting the change in the temperature increase of a measuring point. When the temperature exceeds a temperature limit, warning signals are emitted by an indicating lamp and a relay of an in-situ display terminal and or by a remote management platform, thereby preventing accidents caused by overheated equipments.
