驼峰测速雷达和测长设备抗强电磁干扰解决方案

Solution of Anti-Strong Electromagnetic Interference of Hump Length-measuring Equipment and Speed-measuring Radar

针对太原北驼峰测长、测速雷达系统受牵引电流的强电磁干扰,造成测长系统、测速雷达发生测速指示跳变,频繁夹停、撞钩等危及调车作业安全的问题进行深入研究,结合实际情况,采取针对性措施,对既有测长设备、测速雷达提出改进方案,为现场改造实施提供依据。

The hump length-measuring equipment and speed-measuring radar in the Taiyuan North hump yard was subjected to strong electromagnetic interferences from traction current, which results in some problems endangering the security of shunting operation, such as indication value hopping, frequent abnormal stops, coupler collision and so on. Through in-depth research combined with the actual situation, useful targeted measures are taken and improvements for the existing length-measuring equipment and speed-measuring radar are put forward the, providing basis for the renovation of the station.
