The invention provides a middle-low speed maglev train cross track seam control system based on image processing. An image acquisition module acquires a suspension gap image and a track image through a binocular camera, and an image processing module and a gap calculation module process the images and calculate a suspension gap value d and a track-crossing joint distance L of an electromagnet; a suspension control module compares the received d value with a target suspension gap value, obtains a current value without a track gap through PID adjustment, carries out gap correction on the current value without the track gap through L and d, finally compares the current value with the current current value of an electromagnet to obtain a current deviation, and changes the duty ratio of a suspension chopper through the deviation so as to change the current of the suspension electromagnet, and stable suspension is kept. The dynamic rigidity of the system is improved, and the system has the characteristics of high anti-interference capability, high suspension stability and the like.

    一种基于图像处理的中低速磁悬浮列车过轨道接缝控制系统,图像采集模块通过双目相机采集悬浮间隙图像和轨道图像,图像处理模块和间隙计算模块对上述图像处理并计算悬浮间隙值d和电磁铁过轨道接缝距离L,悬浮控制模块将收到的d值与目标悬浮间隙值比较,通过PID调节得出无轨缝时电流值,并通过L和d对无轨缝时电流值进行过缝校正,最后与电磁铁当前电流值进行比较得出电流偏差,通过该偏差改变悬浮斩波器占空比以此改变悬浮电磁铁电流,保持稳定悬浮。本发明增大了系统的动态刚度,具有抗干扰能力强,悬浮稳定性高等特点。
