通信线路故障监测系统的设计

Failure Monitor System Design for Communication Circuit

为确保通信线路安全、可靠运行,需要远程实时监测通信线路中的故障;为此设计了以89C52单片机为核心,由多模块组成的通信线路故障远程实时监测系统;给出了系统的总体设计方案和各子模块的故障检测原理以及集中器的工作流程,并给出了集中器和各检测子模块之间及集中器和监控中心之间的通信方式;讨论了在实际使用中应注意的问题和处理的方法;实验表明,此系统能对通信线路中的配线架、电缆、工频干扰情况进行远程实时的监测。

A remotely real-time fault monitoring system, which is based on 89C52 microprocessor and composed of multi-module, is designed to ensure the security and reliability of communication circuit. The design scheme of the system, the fault detection principle and the work flow of the collector are introduced. The mode of the communication among the collector and sub modules, as well as the mode of the communication between the collector and control center are given. It has been proved experimentally that this system can be used for remotely real-time monitor of assemble line racks, cables and industry frequency interference of communication circuit.
