The Network Monitoring System Of Program-controlled Switchboard Power Supply

The research on the application of program-controlled switchboard power supply network monitoring system is more and more concerned. Nowadays, the network monitoring system used generally is large. This system transmits information with interface of 2Mbit/s. The quality standard with communication line is strict, and it needs optical cable. As large power-supply monitoring system using all-around monitoring, the amount of signal collection is large, its structure is complicated, the cost of investment is high and the quality standard with technical figures is strict. In a word, it is not suitable to those large number rural area's small capacity switchboard rooms.Based on the research of program-controlled switchboard power supply network monitoring system,a new kind of monitoring system is suggested in this paper. It can be composed of existing telephone network, and it transmits information with the line that it is set up by dialing form, and it is controlled by single chip computer to reach the aim of monitoring system all kinds of information selectively. After experiments and adjust instruments during experimentation, now it is available. Its running result reveals that this system is more adaptable to those small capacity switchboard rooms.At last we summarize this new kind of monitoring system and point out its potential on further research.
