The invention relates to a train fault detection system and method, in particular to an urban rail vehicle wheel tread damage detection system and method, and aims to solve the problem that a wheel tread panoramic image obtained by an existing wheel tread damage detection system is often low in definition, and consequently more errors during damage identification are caused. The urban rail vehiclewheel tread damage detection system comprises a wheel sensor used for generating shooting trigger signals when a wheel passes through the wheel sensor, a control module used for generating a shootingcommand according to the shooting trigger signals, an image acquisition control and processing module used for sending the shooting command to a camera module, and a camera module used for collectingwheel tread partial images after receiving the shooting command and collecting a plurality of wheel tread partial images for the same wheel; the wheel tread partial images are sent to the image acquisition control and processing module; and the image acquisition control and processing module is also used for splicing the plurality of wheel tread partial images of the same wheel into a complete wheel tread after receiving the wheel tread partial images.

    本发明的一种城轨车辆车轮踏面损伤检测系统及方法涉及一种列车故障检测系统及方法,目的是为了克服现有的车轮踏面损伤检测系统得到的车轮踏面全景图像往往清晰度低,造成损伤识别时误差较多的问题,系统包括:车轮传感器,用于在车轮经过时生成拍摄触发信号;控制模块,用于根据拍摄触发信号生成拍摄命令;图像采集控制及处理模块,用于将拍摄命令发送至相机模块;相机模块,用于在接收到拍摄命令后,采集车轮踏面部分图像,且对于同一车轮采集多张车轮踏面部分图像;并将车轮踏面部分图像发送至图像采集控制及处理模块;图像采集控制及处理模块,还用于在接收车轮踏面部分图像后,将同一车轮的多张车轮踏面部分图像拼接为完整的车轮踏面。
