被复线故障检测仪的研制

Study of Checking Decvice for Malfunction of Cable Communication

本文介绍的检测装置以89C51单片机为核心,将故障检测和巡线信号有机结合并将两个功能进行了分时引入,可以对任意类型的被复线实现自动校正、自动测量和智能分析故障类型以及在很小强度人为干预下实现故障的定位。该仪器能对同线的多处故障自动顺序检测以及具有较强的抗干扰能力和较宽的工作电压范围。

The device is center on 89C51 single chip computer and it can examine malfunction cable communication. It has two functions that are examining malfunction and sending out the checking signal. It can automatic rectify, measure and intelligently analyze all kinds of malfunction and realize position of malfunction out of human manipulation little intensity. The instruments can automatic examine lots of malfunction in tandem. Overall, it has been capable of strong interference opposing and wide range of working voltage.
