The invention provides a track inspection imaging control signal generator, a generation method and a track inspection system. The signal generator comprises an accelerometer and an instantaneous speed calculation and signal generation module; train speed and accelerometer signals acquired by an MVB bus are comprehensively utilized, so that the instantaneous speed of a train in any motion state isaccurately calculated in real time; based on the instantaneous speed, according to the mileage pulse signal resolution requirement of an inspection imaging system, the linear array scanning control signals of the inspection imaging system are generated in real time, so that the inspection imaging system mounted on the train performs uniformly scans and images a track to obtain two-dimensional orthree-dimensional data of the surface of the track, so that the data can be applied to track disease detection.

    本发明提供了一种轨道巡检成像控制信号发生器、产生方法和轨道巡检系统,该信号发生器包括加速度计、瞬时速度计算与信号发生模块,综合利用MVB总线获取的列车速度和加速度计信号,实时、准确地计算列车任意运动状态下的瞬时速度,基于瞬时速度、根据巡检成像系统里程脉冲信号分辨率需求,实时产生巡检成像系统线阵扫描控制信号,使挂载于列车上的巡检成像系统对轨道进行均匀扫描成像,获取轨道表面二维或三维数据,用于轨道病害检测。
