The invention discloses a jacking reversing control unit of a trolley. The jacking reversing control unit comprises a magnet, a giant magnetoresistance sensor, a control module and a micro-control unit, wherein the magnet is mounted on the end face of a wheel shaft of a jacking reversing eight-diagram wheel; the micro-control unit judges the rotated angle, relative to the initial angle, of the wheel shaft of the eight-diagram wheel according to the current angle value and judges the position of the eight-diagram wheel; and the control module is used for sending a control signal to the micro-control unit and controlling the rotation angle of the jacking reversing eight-diagram wheel through the micro-control unit. The control unit is stable and effective in structure, is not influenced by detection distance change caused by long-term operation vibration of the trolley, is more stable and accurate in detection, and is convenient to install and easy to maintain.
本发明公开了一种车顶升换向控制单元,包括安装在顶升换向八卦轮的轮轴端面的磁铁、巨磁阻传感器、控制模块、微控制单元;微控制单元通过当前角度值判断八卦轮的轮轴相对初始角度已转动的角度,并判断出八卦轮所处位置;所述控制模块用以向微控制单元发送控制信号,并通过微控制单元控制顶升换向八卦轮的转动角度。这种控制单元的结构稳定有效,不受小车长期运行振动造成的检测距离变化的影响,检测更加稳定准确,且安装方便易维护。
