电缆故障报警自动定位系统设计与实现

Design and Implement of the Cable Malfunction Give an Alarm Automation Fixer System

鉴于电缆的应用越来越广泛,电缆故障的种类越来越多,故障发生的频率也越来越高。本文对于频发的电信电缆中断事故,本文提出了一种电缆故障自动报警定位系统的设计方案。系统采用电容检测法和电阻检测法相结合,根据定期测得的单位长度电容、电阻值,测算出故障电缆长度。实验和应用结果表明,系统结构紧凑、功能齐全、使用简单易学、测量精度高、无误报、成本低廉。

Since the cable application is more and more broad, cable malfunction kind has been more and more, malfunction occurrence frequency has been also more and more high, has broken off an accident to the communication cable frequently happening, has brought forward one kind of cable malfunction give an alarm automation fixer system design plan. System adopt capacitance to check law and electric resistance detecting law being tied in wedlock each other, measures the unit the length capacitance/electric resistance value having according to the regular intervals, measures and calculates the malfunctioning cable length. The result by the fact that the experiment and reality apply is indicated, that system structure is compact, the function is all in readiness, using a implicity is easy to learn, measurement accuracy is high, errorless newspaper, cost is low.
