Abstract

The invention provides a track dynamic measuring system and method. The track dynamic measuring system comprises a longitudinal beam, a transverse beam, a total station instrument, a controller, an inertial navigation device, track gauge sensors and a mileage sensor. By using the track dynamic measuring system and method, the track measuring efficiency can be greatly enhanced on the premise of guaranteeing the absolute measuring accuracy of the track, can avoid problems that GNSS signals are missing in long and bid tunnels and the measuring accuracy does not satisfy the use requirement and can realize the balance between the track dynamic measuring accuracy and the track dynamic measuring efficiency.

Description

technical field [0001] The present application relates to the technical field of measurement and control, in particular to a track dynamic measurement system and method. Background technique [0002] At present, rail transit has increasingly become an important mode of transportation for people to travel. At the same time, modern society has also put forward higher and higher requirements for the safety and comfort of rail transit, that is, it is required to build a track with high smoothness. And three-dimensional absolute position accuracy. The smoothness of the track and the three-dimensional absolute position accuracy can only be judged after the track is measured and analyzed by the track inspection equipment. Therefore, the track inspection equipment that meets the actual operation needs is the premise of building a high smoothness track. [0003] In the prior art, typical application scenarios of static track detection technology are: [0004] 1. Based on the three-...
