Problems solved by technology

For a long time, the static inspection methods of railway tracks in my country have been relatively backward, and the inspection mode of "track ruler + artificial string + manual report" is still widely used so far. The efficiency of the equipment is low, the labor intensity of the workers is high, the detection accuracy and data completion are poor, and the information transmission slow

Embodiment Construction

[0053] Such as figure 1 and figure 2 A method for measuring the unevenness of rail tracks based on a single-axis gyroscope includes the following steps:

[0054] Step 1. Installation of single-axis gyroscope:

[0055] Step 101, fixing the single-axis gyroscope 1 on the rail inspection vehicle; wherein, the angle between the measurement axis of the single-axis gyroscope 1 and the moving direction of the rail inspection vehicle is 0° or 180°;

[0056] Step 102, placing the rail inspection car equipped with the single-axis gyroscope 1 on the rail to be tested;

[0057] Step 2. Acquisition of the angular velocity output by the single-axis gyroscope:

[0058] Step 201, the rail inspection car is stationary for 5 minutes to 10 minutes for the ath time; wherein, the speed and angular velocity of the rail inspection car are both zero; a is a positive integer, and a≥1;

[0059] Step 202, when the rail inspection vehicle is still for the a-th time, the data processor 3 collects the...

Abstract

The invention discloses a rail height irregularity measurement method based on a single-axis gyroscope. The method includes the steps: firstly, installing a single-axis gyroscope; secondly, acquiringthe angular speed outputted by the single-axis gyroscope; thirdly, processing the angular speed outputted by the single-axis gyroscope; fourthly, acquiring rail irregularity data. The method is simplein step, reasonable in design, low in implementation difficulty and high in practicability, only needs the single-axis gyroscope and a speedometer and can be widely applied to measurement of variousrails, and measurement accuracy is ensured through zero point correction and filtering.

Description

technical field [0001] The invention belongs to the technical field of rail deformation measurement, in particular to a method for measuring rail height irregularity based on a single-axis gyroscope. Background technique [0002] Rails are the basis of train movement, and railway trains are guided by rails when they are in motion. Whether the parameters of the rail meet the requirements is related to the safety of train movement and the comfort of passengers. Under the influence of rolling stock dynamics and natural erosion, railway lines not only undergo elastic deformation (that is, the line returns to its original shape after the load is removed), but also produce permanent deformation. Among them, the permanent deformation can be divided into two categories: one is the change of geometric position, such as line crawling, poor direction, gauge expansion and reduction, etc.; the other is the wear of various parts of the rail, such as the wear of the rail. The existence o...
