AI Technical Summary

Benefits of technology

The present technology uses controlled switches like solid-state relay (SSR) devices to generate pulsating currents along an electric conductor without affecting any nearby electrical equipment. This allows accurate monitoring of buried wires while reducing false alarms caused due to incorrect identifications during site visits. Additionally, the use of SSR devices simplifies the process of finding hidden underground cabling within stations helps prevent mistakenly attributing users who are unaware about them being located inside their premises.

Problems solved by technology

This patented technical problem addressed in this patents relates to finding the location of electricity usage within specific locations without requiring expensive equipment like meters. Current methods require manual input from operators who manually locate each site with identifiers attached thereto before connecting wires to their respective devices.

Embodiment Construction

[0055] In order to realize cable detection, the cable detection device of the present invention mainly includes: a terminal unit for generating pulse current, and a hand-held pulse detector for tracking and detecting the generated pulse current. The terminal unit is connected to the user end or end of the power line in parallel, including the pulse control module and the action module connected in parallel to the user end or end of the power line, wherein,

[0056] The pulse control module is used to sample the AC voltage at the user end or end of the power line, and send a conduction control signal that lasts for a preset duration to the action module. It should be noted that the specific implementation of sampling the AC voltage and generating the conduction control signal belongs to the common technical means of those skilled in the art, for example, it can be realized by a single-chip microcomputer, DSP or programmable logic device, and will not be described in detail here. ...

Abstract

The invention discloses a cable detecting device and a method thereof for realizing detection. The scheme is as follows: continuous transient pulse current is generated in a circuit by cutting off controllable switch elements, such as a solid relay, a thyristor, a transistor, an IGBT, and the like after continuously and transiently communicating the controllable switch elements at the user end or the tail end of an electric power circuit, and a cable is detected by tracing the pulse current. In the method, because the pulse current can not be spread to other irrelevant circuits, a pulse current signal can not be interfered by the electric power circuit. The method for detecting the cable by the cable detecting device ensures the accuracy of cable detection. The invention also discloses a station user identification apparatus integrated with the cable detecting device, which prevents erroneous judgment and unavailable judgment in station identification and ensures the identifying accuracy.
