Railroad sleeper detection data acquisition device and system

Abstract

The invention discloses a railroad sleeper detection system. The railroad sleeper detection system comprises a railroad sleeper detection data acquisition device and a data processing system. The railroad sleeper detection data acquisition device comprises a force exerting device, a pressure sensor (3), a displacement sensor (4) and a multi-channel data acquisition instrument (5). The pressure sensor (3) and the displacement sensor (4) conduct sleeper pressure measurement and sleeper displacement measurement and are connected with the multi-channel data acquisition instrument (5) through cables respectively. The multi-channel data acquisition instrument (5) is further connected with the data processing system. The data processing system comprises a digital processing device (61), a load displacement analyzing and processing module and a data output device. The load displacement analyzing and processing module is arranged in the data processing device (61). The railroad sleeper detection system can detect the load displacement of a rail and is high in detection speed, high in precision, high in stability, less in error, little in manual work, high in efficiency, safe and reliable.

Description

technical field [0001] The invention relates to a railway detection system, in particular to a railway sleeper detection data acquisition device and system; the system is mainly used for the detection of the railway sleepers on the railway, and in particular is used to detect the track (ballasted track) in the The vertical support stiffness of the sleeper, the lateral resistance of the sleeper and the longitudinal resistance of the sleeper are used as the evaluation of the quality of ballast laying or maintenance and maintenance of the ballast track; the data acquisition device is mainly used for the railway sleepers on the railway. data collection during detection. Background technique [0002] In order to ensure the traffic safety of the track (including railway, urban rail and other traffic ballasted track, the same below), it is often necessary to test the vertical support stiffness of the sleeper, the lateral resistance of the sleeper, and the longitudinal resistance of...

AI Technical Summary

Problems solved by technology

At present, the main method of testing the performance indicators such as the vertical support stiffness of the sleeper, the lateral resistance of the sleeper, and the longitudinal resistance of the sleeper in the track is to use a jack and a dial indicator for detection, and the data acquisition mainly relies on manual reading of the oil pump connected to the jack. The pressure gauge and the dial indicator connected to the beam (displaced at the same time as the sleeper): Then convert the reading of the pressure gauge into the pressure value of the jack 11, and the dial gauge can read the displacement value of the sleeper due to the pressure of the jack; Although this method can also detect performance indicators such as the vertical support stiffness of the sleeper, the lateral resistance of the sleeper, and the longitudinal resistance of the sleeper, it has the following shortcomings: 1. This detection method is mainly directly operated manually (relying on human senses) Mainly, that is, mainly manual reading, manual recording, and manual calculation, the detection error is large, the human influence factors are relatively large, and manual measurement is difficult to meet the requirements of detection accuracy. For example, the existing manual reading of the dial gauge has a large deviation, Inconsistent readings before and after

Especially in the case of poor testing environment, heavy testing burden, and long process, testing personnel are prone to fatigue, slack, or mistakes due to haste, resulting in large dispersion of measurement data; 2. Specially equipped with fixed instrument reading personnel, personnel The quantity requirement is large; 3. There are large safety hazards. Because a large amount of manpower is required, the inspection site is located in the track operation line section, and all inspection personnel need to work on the operation line, which is prone to personal safety hazards on the line; 4. A large number of manual measurement operations, The error rate is greatly increased, and the information transmission between the various operators will also be wrong and delayed, which may cause a large number of detection errors caused by personnel factors; 5. After the original data collection is completed, the data must be manually sorted, Analysis and calculation are cumbersome, error-prone, and take a long time in the office; 6. The inspection equipment is heavy, there are many inspection accessories, the inspection efficiency is low, and there are many management links
