The utility model discloses a novel switch cabinet wireless temperature sensing centralized monitoring system which comprises an infrared temperature sensor, a temperature control meter, a concentrator and a system main station. Wherein the infrared temperature sensors are used for collecting multi-point environment temperature of a single switch cabinet, and the plurality of temperature sensors transmit data to the temperature control meter through RS232/RS485 interfaces respectively configured on the plurality of temperature sensors; the temperature control meter is used for receiving the analog signal input by the infrared temperature sensor and displaying the analog signal on the temperature control meter; the system main station is used for monitoring real-time temperature data and historical data in the temperature control meter and setting corresponding parameters in the concentrator, the multi-point monitoring system is used for monitoring the temperature measurement nodes of all the switch cabinets of the whole transformer substation, the structure is simple, and installation and networking are convenient. The communication protocol is simple, single-point to multi-point temperature monitoring can be adopted, the anti-interference performance is high, and engineering application is facilitated.
