A temperature remote monitoring system of cable joint

In order to monitor the temperature of cable joint, this paper designed a cable joint real-time temperature monitoring system based on GPRS which is integrated of computer technology, microcomputer control technology and digital sensor technology. It described the whole structure diagram of the system, and presented the hardware circuit and software design in detail. The system takes SCM as main control chip, adopts DS18B20 to build up the temperature measurement terminals, and uses the GPRS network as a wireless transmission network to realize wireless data transmission through the TCP/IP protocol management. Experimental results show that: the system have high accuracy, it is able to identify a variety of cable faults caused from overheating effectively and can meet the needs of cable temperature monitoring.
