Design of Temperature Monitoring System for Overhead Contact Line Based on ZigBee and GPRS


The traditional temperature measure methods of Overhead Contact Line (OCL) could not satisfy the requirement of measuring precisely and transferring rapidly. Thus, based on ZigBee wireless sensor network and GPRS communication technology, a new temperature monitoring system was presented in this paper. The system consisted of temperature collection terminal, routing concentrator and GPRS coordinator. According to the characteristics of connectors distribution of OCL, a three-layer network was proposed, which could transfer the collected temperature data remotely. The related hardware schemes and software flows were given. Test results showed that this system could effectively collect and transfer temperature data.
