文章阐述了一种基于电阻网络的网线故障检测装置,基于电学原理在网线周围构造电阻网络,并结合电阻一次性测量方法,使其在没有短路或断路状态时测得的阻值与网线内部有短路或断路的坏网线情况下所测得的阻值不相同。通过实验确定出网线良好时的电阻阻值,并将该阻值作为基础与以后的检测值作为比较。此方法克服了传统检测方式中的繁琐过程,提出了新型的网线状态判断方法,实现了低成本。
This paper describes a network cable fault detection device based on the resistance network. Based on the electrical principle, a resistance network is constructed around the network cable. Combined with the resistance one-time measurement method, the resistance value measured in the absence of a short circuit or an open circuit condition is compared with the internal The resistance measured in the case of a short circuit or a broken network cable is not the same. The resistance value of the wire when the network cable is good is determined through experiments, and the value of the resistance is taken as a basis for comparison with the later detection value. This method overcomes the tedious process in the traditional detection methods and proposes a new method for judging the status of the network cable and realizes low cost.
