The thesis based on Yellow River Diversion Project. Through the research of the existing design of the supervising system of Yellow River Diversion Project, this passage pointed out some problems hard to be dealt with as follows:(1) Owing to the dispersion of control points and remote transfers of data, it cost a lot to construct the network of the supervising system and it was hard to implement the construction.(2) The connection mode of network needed to be taken into acount. Once the configuration of network changed or the nodes increased, the supervising system needed to be reconfigured.(3) Owing to the tanglesome physical communication line, the man-made communication error happened frequently.(4) When the communication malfunction occured, it needed various engineers to check and repair the fault.(5) It cost a lot to operate and maintain the supervising system.
本文以世界银行援建项目&Yellow River Diversion Project&(引黄入晋工程,编号:0015-K81062)为背景,在对引黄入晋工程的远程监控系统进行研究分析的过程中,指出了该系统在目前采用的有线光纤和有线电缆通讯技术下难以处理的一些问题:(1)由于监控点分散且传输距离较远,有线光纤和有线电缆的网络建设成本很高,实施困难;(2)需要考虑节点之间的连接形式,一旦网络结构发生变化或节点需要扩充,监控系统便需要调整,耗费大量的人力物力;(3)由于系统庞大,通讯的物理线路较为繁乱,在建设和维护阶段容易出现人为触碰等引起的通讯故障;(4)在出现通讯故障时,需要多方人员配合进行故障检测,不仅耗费人力和物力,且不利于故障排除;(5)运行和维护成本较高,需要很多运行维护人员进行大量繁杂的工作。

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。
