Track parameter measuring and calculating system and method for track inspection tester

Abstract

The invention provides a track parameter measuring and calculating system for a track inspection tester. The system comprises a trigger module comprising a drive unit and a position encoder connected with a drive motor, a laser scanning module comprising a data acquisition unit connected with the position encoder and a data processing unit connected with the data acquisition unit , a main control module comprising a storage unit connected with the data processing unit and an analysis unit connected with the storage unit , and a display module connected with the storage unit of the main control module. The system is overall modularized, low in composition cost, small in structure and convenient to install, the labor intensity of workers is greatly relieved, and the track geometric parameter measurement precision is improved.

Description

technical field [0001] The invention belongs to the technical field of track inspection, and in particular relates to a track parameter measurement system and a measurement method of a track inspection instrument. Background technique [0002] The track inspection instrument is mainly used to detect the static geometric parameters of the track, that is, gauge, level (or superelevation), left and right rail direction and positive vector, left and right height, and triangular pits. It is the most basic instrument and equipment to ensure driving safety. At present, there are relatively few manufacturers of track inspection instruments, so the equipment is relatively small and expensive, so the cost of track inspection is relatively high, and the existing track inspection instruments cannot measure when the rail or subway transition radius is relatively large, so they cannot be applied to subways A variety of scenarios in the measurement, also cannot accurately predict the wear ...
