Design of Device and Method for Non-Intrusive Anti-Braking Cable Monitoring

With the rapid development of urban construction, there are more and more civil engineering construction which take place in a certain scale of area in most cities during recent years. Power supply faults caused by the construction occur frequently, which are somehow even hard to be prevented. Therefore, it is necessary and of great importance to develop a technology that can forewarn the cable to be cut or broken in advance. Till now, there are already many scholars who have studied the issue of status monitoring for all types of cables, however, there are hardly any technical means in power supply system to realize anti-breaking function for cables during engineering construction. Even if there are some reports shows the monitoring system design which can prevent the occurrence of cable failure due to engineering construction, but it cannot determine whether the construction is in the cable area so that it may be easy to cause false alarm. In this paper, a non-invasive anti-breaking cable monitoring device and method has been proposed, which can send an alarm before the cable is cut, and can notify the nearby operation and maintenance personnel to check, thus the safety of the cable can be ensured.
