For monitoring temperature of substation high voltage switch cabinet conveniently,reliably and real-timely,the temperature monitoring system based on CAN bus and wireless radio frequency technique was developed. Using nRF2402 and DS18B20 as the main devices for designing wireless temperature sensor to collect and transport node temperature of high voltage switch cabinet. Wireless temperature collector was designed based on nRF2401 and independent CAN controller-MCP2510, its function is to communicate with temperature sensor and host computer. The whole system realizes monitoring and alarming to node temperature of high voltage switch cabinet. The system runs on a 110 kV substation and the executing result shows that it has strong anti-interference ability and is accurate, reliable and can meet the temperature monitoring requirement of high voltage switch.
