Track line dynamic information acquisition device

Abstract

The invention discloses a track line dynamic information acquisition device. The device consists of a balance device, a digital sensor, and a line dynamic detection device. A foundation of the balance device is connected with balance columns which pass through balance assemblies and a mass template; the mass template is provided with the digital sensor which is respectively connected with three paths of circuits which have the same structure; one path of the circuits is respectively connected with a signal source, a signal amplification circuit, a high pass, a low pass, a reference circuit, acentral processing unit (CPU) and a 485 communication interface; and a dynamic detection systems consists of an acquisition module, a storage, a state circuit, an alarming module, a general packet radio service (GPRS) module, a short message platform, a server, a railway administration website, an automatic generation report module, a station stage website, and a mobile computer. The device detects data, such as inward and outward deformation value in the horizontal direction of a left rail, the upward and downward deformation value in the longitudinal direction of the left rail, the inward and outward deformation value in the horizontal direction of a right rail, the upward and downward deformation value in the longitudinal direction of the right rail, a triangular hole, a horizontal direction, steel rail breakage and the like and horizontal and vertical swing acceleration speed values of a vehicle body under the dynamic state of the track line. The track line dynamic information acquisition device can be widely used for quality detection of railways, underground, coal mines, metallurgy, and mine track lines.

Description

technical field [0001] The invention relates to a dynamic detection device for rail transit lines, in particular to a dynamic information collector device for rail lines. Background technique [0002] At present, in terms of track dynamic detection in China, no matter whether it is the vehicle shaking instrument, the multi-ride instrument or the track signal acquisition part of the track inspection vehicle, it is basically not in rigid contact with the rail, and the authenticity of the signal will inevitably be affected. The theoretical basis for judging the route mode based on the acceleration of the vehicle body is very insufficient, and is greatly affected by factors such as speed and vehicle type. To accurately detect the track line, the signal acquisition part must be in rigid contact with the rail. [0003] The vehicle-mounted car shaking instrument and multi-ride instrument used in domestic railways can only detect the vertical and longitudinal acceleration values ​​...

AI Technical Summary

Problems solved by technology

Therefore, it is not scientific and comprehensive to judge the line by the shaking acceleration of the car body, and there is a defect that the indicators of g and wavelength are not used in the railway line maintenance regulations.

[0004] The track inspection vehicles used in China mainly have the information collection part of the inspection data not in rigid contact with the rail, and the inspection data needs to be corrected by a complex data correction system, which is expensive And the huge and complex data processing system is a defect that the number is limited and it is impossible to realize the all-weather monitoring of the track line
