停电

Adopting multiplexing technique and making use of communication line between CSC and CS to achieve simultaneous transmission of ISDN signal and electric power. According to the variation of circuit equivalent resistance to design detection circuit, which can judge that the line is short circuit or open circuit and the commercial power is working normally or failure. When the reserve power supply is working, the system judges its operation status by voltage and current detection circuit. Making use of the characteristic of the gas discharge tube to achieve suspension system detection of power line touching. Transmitting information collected up to PC by RS485 for the purpose of centralized monitoring.

采用复用技术，利用基站控制器和基站间的通信线路实现ISDN信号和电力的共同传输；根据线路等效电阻的变化设计探测电路，来判断开路、短路、市电供电、市电停电等情况；在后备电源工作时，通过电压、电流采样电路判断电源的运行情况；利用气体放电管的特性实现悬浮系统动力线搭接的检测；采用RS-485通信方式将采集到的现场信息上传以实现集中监控。
