Embodiment Construction

[0066] The invention provides a wheel size detection system. figure 1 It is a schematic structural diagram of a wheel size detection system provided by the present invention. Such as figure 1 The system shown includes: at least 6 distance sensors 1, a data acquisition card 2 and a controller 3. Each distance sensor 1 is connected to the data acquisition card 2, and the data acquisition card 2 is connected to the controller 3. Among them, at least 5 The distance sensor 1 is located on one side of the track 4; at least one distance sensor 1 is located on the other side of the track 4, and there is at least one distance sensor 1 in the distance sensor 1 on one side of the track 4, and the distance sensor on the other side of the track 4 1 Symmetrical setting.

[0067] Each distance sensor 1 is used to collect the distance information between the location of each distance sensor 1 and the wheel of the vehicle under test, and send the distance information to the data acquisition card ...

Abstract

The invention provides a wheel size detection system and method. The wheel size detection system comprises at least six distance sensors, a data acquisition card and a controller. Each distance sensor is connected with the data acquisition card. The data acquisition card is connected with the controller. At least five distance sensors are arranged at one side of the track. At least one distance sensor is arranged at the other side of the track. At least one distance sensor in the distance sensors arranged at one side of the track is arranged in a way of being symmetrical with the distance sensors arranged at the other side of the track. According to the wheel size detection system and method, the size of the wheels of a vehicle to be measured can be detected and calculated and then the worn situation of the wheels can be determined according to the size of the wheels so that the safety accident caused by the change of the wheel size can be avoided.

Description

Technical field [0001] The invention belongs to the technical field of locomotives, and relates to a wheel size detection system and method. Background technique [0002] In rail transit, the train wheels, as the connecting part of the train and the track, carry the weight of the entire train, and are an important component of the train running system. [0003] During the operation of the vehicle, the wheels constantly rub against the surface of the rail, which easily leads to wear of the wheels. At the same time, due to the very poor working environment of the train wheels, poor line maintenance conditions, unreasonable wheel-rail shape and material matching, etc., the wheels can be damaged. The geometric dimensions have changed. [0004] The changes in the dimensions of the wheels will affect the smoothness of the vehicle operation, and even lead to rollovers, derailments, etc., resulting in potential safety hazards in train operation. Summary of the invention [0005] The inventi...
