摘　　要：在行车密度较低的环境下,一般采用DX3型道口信号设备作为列车接近和到达探测设备。该设备以轨道电路为基础,有时会产生严重的分路不良现象,造成行车安全隐患。为解决上述问题,提出采用计轴设备,实现该型道口的列车接近和到达探测,是一种相对比较经济和可靠的解决方案。In locations with low traffic density, DX3 type level crossing signaling device is often adopted as the detector of train approaching and arrival. This device is based on track circuit and serious poor shunting may occur from time to time, thus causing safety hazards for train opera- tion. To address the problem, it is proposed that axle counting device be adopted to detect train approaching and such a continuous check mode would be more economical and reliable.
