Cable external damage prevention early warning device and method

Abstract

The invention relates to a cable external damage prevention early warning device and method. The device comprises a single-chip microcomputer module, a signal transmission lead, a sound-light alarm module and a power supply module. The power supply module is used for supplying power to the single-chip microcomputer module and the sound-light alarm module. The single-chip microcomputer module comprises a signal output end and a signal receiving end. The signal output end is used for sending a signal A, the signal receiving end is used for receiving the signal A, the signal transmission lead isused for transmitting the signal A sent by the single-chip microcomputer module to the signal receiving end of the single-chip microcomputer module, and the sound-light alarm module is connected withthe single-chip microcomputer module through a relay and is used for sending sound and light alarm signals. The technical scheme is suitable for a newly laid cable line and is also suitable for an oldcable line, is low in maintenance and replacement cost, and achieves early warning of a possible cable external damage event so as to effectively prevents improper excavation operation. A personal electric shock accident is avoided, damages to power facilities are prevented, power failure is avoided, an ' 'advanced operation and maintenance service' ' is realized, and power utilization satisfaction of a user is improved.

Description

technical field [0001] The invention relates to the technical field of power transmission line auxiliary equipment, in particular to a cable breakage prevention early warning device and method. Background technique [0002] Electric power enterprises are special industries that serve the whole society. The production and operation activities of electric power enterprises are not only directly related to the work and life of employees in this industry, but also closely related to the development and stability of the whole society. "Quality service is the lifeline of power grid companies" as the power The core concept of the enterprise is to actively fulfill the social responsibilities of state-owned enterprises. Through continuous innovation to provide better services, change "passive problem handling" into "active problem prevention", so that ordinary people "feel the happiness index because of electricity." "It is the goal that every electric power person strives for at pre...

Problems solved by technology

[0003] For the problem of external damage to the cables laid below the ground, the power supply company is often in a passive position with hindsight, and usually actively rushes to repair the cable after the cable is broken. Large or small economic losses are caused, which leads to conflicts between the power supply department and users, and can easily lead to complaints about the quality of power supply. Therefore, preventing cable breakage is an important issue faced by power supply companies

[0004] At present, the power supply company has no specific preventive measures, and can only prevent it by strengthening inspections and setting up signage. In order to change this situation and realize the real change from passive to active, it is necessary to develop a cable breakage prevention early warning device, to detect potential factors that may cause cable breakage in time, prevent the occurrence of cable breakage incidents, and improve user satisfaction
