Abstract

The invention provides a railway vehicle wheel pair diameter dynamic state detecting system and relates to a technology of railway vehicle wheel pair detecting. The system aims to solve the problems that an existing manual detecting method is high in work intensity and low in working efficiency, and cannot detect the diameter of train wheel pairs in the operating process in real time. A light source and a camera of the system are installed between two steel rails and between two adjacent sleepers. The camera is used for obtaining an axle curve image formed by irradiation of the light source toan axle. The light source serves as a compensation light source of the camera. A wheel sensor is arranged on the side wall of a rail, a vehicle passes through the wheel sensor in priority, and then passes through the light source and the camera; wheel pair position information serves as a trigger signal of the camera; and after the camera obtains the image, a computer processes the image, and thediameter data of the vehicle wheel pairs are obtained. The system has the beneficial effect that the diameter of the train wheel pairs in the operating process can be detected in real time.

Description

technical field [0001] The invention relates to a railway vehicle wheel set detection technology. Background technique [0002] With the development of railway transportation in the direction of high speed, high density and heavy load, the wear of the tread and rim of the vehicle wheel is becoming more and more serious, which leads to the change of the diameter of the wheel and the change of the matching relationship between the wheel and the rail, which not only aggravates the Damage to structural components leads to higher railway transportation costs and directly affects the safety of railway transportation. In order to ensure the safety of train operation, the railway department stipulates that running trains should regularly detect the wheel status to determine whether the wheels should be overhauled or scrapped. [0003] The diameter of the vehicle wheel set is an important parameter of the state data of the train wheel. Due to its large size, the diameter of the whee...
