Distance measuring system for distance measurement in cable laying

Abstract

The invention discloses a distance measuring system for cable laying distance measurement. The distance measuring system comprises a laser distance measuring instrument, multi-angle rotating mirrors and a reflector, wherein the laser distance measuring instrument, the multi-angle rotating mirrors and the reflector are all arranged in a cable shaft; the laser distance measuring instrument is arranged at one end of a distance measurement path below the cable shaft, and the reflector is arranged at the other end of the distance measurement path; in the distance measurement path, the multi-angle rotating mirrors are arranged; laser emitted by the laser distance measuring instrument enters the reflector after being sequentially reflected by the multi-angle rotating mirrors and then is sequentially reflected by the multi-angle rotating mirrors back to the laser distance measuring instrument; the laser distance measuring instrument comprises a single-chip microcomputer, a distance measurement display module, a temperature detecting module, an alarm module, a driving circuit, a laser transmitting probe, a laser receiving probe and a signal processing circuit. The distance measuring system for cable laying distance measurement has the advantages of the capability of measuring nonlinear distance, realization of the distance measurement of lines with turning points, improvement on convenience in cable laying and the like.

Description

technical field [0001] The invention relates to a ranging system for cable laying ranging. Background technique [0002] The distance measuring instruments in the prior art are mainly divided into military and civilian use. The military instruments are more precise, the measurement distance is longer, and the accuracy is higher. The cable laying laser distance measuring instrument does not require very high accuracy, and the accuracy unit can be within meters. Enough to meet engineering needs. In the prior art, most of the laser distance measuring instruments can only complete straight-line distance measurement, which is not suitable for the laying process of secondary cables. The laying of secondary cables has the characteristics of complex cable laying paths and many inflection points, and not only horizontal laying, but also many problems such as vertical laying in space. [0003] In the prior art, since there is no light adjustment device for laser distance measurement...

Problems solved by technology

In the existing technology, most of the laser distance measuring instruments can only complete the distance measurement in a straight line, which is not suitable for the laying process of the secondary cable

The laying of secondary cables has the characteristics of complex cable laying paths and many inflection points, and not only horizontal laying, but also many problems such as vertical laying in space.

For distance measurements with inflection points, it is impossible to perform
