Static smoothness detecting system and static smoothness detecting method of railway

Abstract

The invention discloses a static smoothness detecting system and a static smoothness detecting method of a railway. The static smoothness detecting system of the railway comprises a client, a laser tracker and a rail detection trolley, wherein the client is communicated with the laser tracker in a wired manner, the client and the rail detection trolley are respectively connected with a wireless communication module, the rail detection trolley comprises a single chip, a displacement sensor, an inclined angle sensor and a target sphere, the displacement sensor is arranged inside a framework of the rail detection trolley, a measurement magnetic ring of the displacement sensor is linked with a moving end of the rail detection trolley, an X axis of the inclined angle sensor is parallel to a cross beam of the rail detection trolley, data measured by the displacement sensor and data measured by the inclined angle sensor are integrated onto the single chip by means of a serial mode, the target sphere is mounted on the rail detection trolley, and the client is communicated with the single chip through the wireless communication module. According to the static smoothness detecting system and the static smoothness detecting method of the railway disclosed by the invention, railway detection efficiency can be increased effectively.

Description

technical field [0001] The invention relates to the field of track static smoothness detection, in particular to a track static smoothness detection system and method. Background technique [0002] At present, three-dimensional measurement method is generally used in the measurement of static ride comfort of high-speed railway and urban traffic track. The equipment used in this method is mainly the integrated system of the total station and the track inspection trolley. There are already many mature products or systems at home and abroad. This method mainly adopts the fixed-point measurement method, and adopts the "stop-and-go" measurement method. During the measurement, the rail inspection trolley needs to stay at the sleeper for a few seconds. Judgment, mileage accuracy requirements are low, and data collection is performed during the stay. This is actually a static measurement method, the measurement data interval is relatively large, and the measurement speed is relati...

AI Technical Summary

Problems solved by technology

Due to the long operation time of high-speed railways and urban traffic and the short window time, this static measurement method is difficult to meet the needs of high-speed measurement during operation and maintenance
