The invention discloses a rail visual inspection system. The system comprises a power supply module, a vehicle MVB bus interface, an imaging control module, a visual imaging module, a data acquisitionmodule and a data processing module. A vehicle speed signal is obtained by using a vehicle MVB bus. A high-precision mileage pulse signal is calculated in real time according to the vehicle speed signal and is used for imaging trigger control of the visual imaging system, so that high-resolution sampling control of the visual imaging system is realized under the condition of no photoelectric encoder, and a 2D or 3D image of the surface of the high-sampling-rate track is obtained. The visual inspection system is mounted on the electric passenger car, daily inspection is achieved, the situationthat a maintenance window period at night is occupied is avoided, enough time is reserved for rail maintenance at night, and the running safety of urban rails can be more effectively guaranteed.

    本发明公开了一种轨道可视化巡检系统,该系统包含供电模块、车辆MVB总线接口、成像控制模块、视觉成像模块、数据采集模块、数据处理模块;本发明利用车辆MVB总线获取车辆速度信号,再根据车辆速度信号实时计算高精度里程脉冲信号,用于视觉成像系统成像触发控制,实现了实现了在没有光电编码器的情况下,视觉成像系统的高分辨率采样控制,获取到高采样率轨道表面2D或3D图像;本发明的视觉可视化巡检系统挂载于电客车上,实现了每日巡检,且避免了占用晚上的检修窗口期,为夜间检修轨道留足时间,更能有效保障城市轨道运行安全。
