电缆故障定位系统设计与实现

The Design and Implementation of Telecommunication Cable Fault-locating System

针对频繁发生的电信电缆中断事故问题,提出了一种电缆故障自动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、测量精确度高、无误报、成本低.

According to the sudden-break accidents that frequently happened in telecommunication cable, a new design project of Cable Auto-locating System is together. Capacitance and resistance measurement are adopted The capacitance/resistance value in unit-length is figured and figured out and the length of broken cables is measured out. And the whole system has tightly constructed with complete functions. It is easy to learn, lowcost, and has the functions of voice cues and common telephones.
