矿用无轨胶轮车泊车辅助装置设计

Design of auxiliary parking device of mine-used trackless rubber-tyred vehicle

针对无轨胶轮车倒车存在的安全隐患，设计了矿用无轨胶轮车泊车辅助装置，详细介绍了该装置倒车距离信号、图像信号、车辆行进方向信号和切换开关输入信号的采集原理。实际应用结果表明，该装置性能稳定可靠，能够有效监测400-2 000 mm倒车距离，倒车视频图像能够在低照度环境下清晰显示，解决了在视线受阻区域倒车的安全问题。

In view of hidden security trouble in astern running for trackless rubber-tyred vehicle, an auxiliary parking device of mine-used trackless rubber-tyred vehicle was designed, and acquisition principle of signals of astern running distance, image, running direction of the vehicle and input signal of switchover of the device were introduced. The practical application result shows that the device has stable and reliable performance, and can effectively monitor 400-2 000 mm astern running distance and clearly display video image of astern running under low illumination environment, which solves security problem of astern running in unsighted area.
