For existing cable connector temperature monitoring system is mostly due to the on-site monitoring equipment supply difficulties, wiring complexity, difficult maintenance and other issues, not large-scale use. Developed a new type of monitoring system. The system uses a low-power digital temperature sensor DS18B20 realize the temperature underground cable joint acquisition, integration C8051F MCU through the internal generation ultra-low power radio frequency chip CC2530 close communicate and use global system for mobile communication system (GPRS) networks to achieve remote data transmission, remote monitoring and management to complete. The system realizes the collection and processing of data cable connector temperature, the temperature curve display, data analysis and preservation, temperature limit alarm and other functions, which greatly improves the life of the cable connector.
