Abstract

The invention relates to a monitoring device for the cross and span distance of an overhead power transmission line, in particular to a monitoring device for the cross and span distance of an overhead power transmission line based on the single chip microcomputer control, and solves the problems that a conventional overhead power transmission line cross and span distance monitoring technology is low in efficiency, poor in environment adaptability, poor in real-time property, poor in view and the like. The device comprises a laser distance measuring device and a central control device, wherein the laser distance measuring device comprises a spherical shell; the spherical shell comprises a microprocessor chip, a laser distance measuring sensor and a radio frequency transmitting module; the central control device comprises a shell and an internal control circuit; the internal control circuit comprises a microprocessor, a temperature sensor, a radio frequency receiving module and a wireless transmission module; the temperature sensor is led outside the shell through a conducting wire and is positioned inside a circular spherical shell which can sleeve an overhead power transmission line. According to the invention, the real-time measurement on the cross and span distance of overhead power transmission lines, communication lines, roads, railways, rivers, houses and the like can be implemented.

Description

technical field [0001] The invention relates to a monitoring device for crossing and crossing distances of overhead power transmission lines, in particular to a monitoring device for crossing and crossing distances of overhead power transmission lines based on single-chip microcomputer control. Background technique [0002] When overhead power transmission lines cross with power lines, weak wires (telephone lines, cable TV, optical cables and other communication lines) and above-ground and underground structures, it is necessary to measure and monitor the crossing distance. At present, the commonly used line crossing monitoring generally adopts theodolite, total station, GPS-RTK positioning technology, laser rangefinder and other technologies, and these technologies are used to comprehensively apply the suspension height measurement method, GPS combined with total station method, air rendezvous method, etc. Methods Measure and monitor the elevation and crossing angle of cros...
