基于传感器的电缆防破损报警系统设计

Design of Cable Anti-Breakage Alarm System Based on Sensor

目前,随着社会的快速发展,对电缆需求量很大。铜电缆破损的增加,主要是由于布局分散、材料成分铜含量高等特点所致。电力运营商等公用事业企业作为主要目标,面临着诸多困难和风险。由于电缆破损,消费者不能在其场所使用电话系统或互联网服务。这些影响了家庭、客户和商业目的之间的沟通,包括紧急情况下的沟通。因此,为了防止电缆破损的普遍存在,这项工作创造了一种装置,能够报警负责人时,在一个指定的位置电缆已被切断或调质的破损。已经为这项工作开发了一个原型。一旦发现电缆破损或被切断,该系统将自动激活报警,并提供一个显示器,以指示电缆破损的具体位置。系统由单片机(PIC16F877A)控制。这项工作是使用电缆馈线,其中的电阻并联的安排决定了电缆的距离终止借助于分压器的概念。

At present,with the rapid development of society,the demand for cable is very large.The increase of copper cable breakage is mainly due to the characteristics of dispersed layout and high copper content in materials.Electric power operators and other public utilities as the main target,facing many difficulties and risks.Because of broken cables,consumers can not use telephone systems or internet services in their premises.This affects communication between family,customer,and business goals,including in emergencies.Therefore,in order to prevent widespread cable breakage,this work creates a device that can alert the responsible person when the cable has been cut or tempered at a designated location for breakage.A prototype has been developed for this work.If a cable is found broken or cut,the system automatically activates the alarm and provides a display indicating the exact location of the broken cable.The system is controlled by single chip microcomputer(PIC16F877A).This work is done using a cable feeder,where the resistance parallel arrangement determines the distance of the cable termination with the help of the divider concept.
