The safety of locomotive shunting operations has always been a bottleneck problem that plagues the development of the railway industry. Many marshaling stations use plane wireless shunting systems and incorporate them into the microcomputer interlocking control system, which plays an important role in improving the efficiency of shunting operations and ensuring the safety of shunting operations. However, due to the restriction of the track circuit in the station and the inability of interlocking the ground shunting signal with the locomotive monitoring device to implement safety control, when the locomotive runs to the signal lights, turnouts, derailment devices, and earth blocks, it still depends on the driver and passengers to look for confirmation. In addition, in the case of rainy weather and manual misoperation, it is easy to cause "rush, squeeze, and pull off" and rush into the locomotive. In view of the development and use status of the above shunting operations, combined with the actual production situation of shunting and transportation of heavy-duty trains with 10,000 tons and 20,000 tons in the actual operation of Shuohuang Railway, on the basis of plane shunting equipment, microwave radar ranging monitoring technology is used to realize the monitoring of safety information such as the location of the operator's work site and the location of the parking vehicle. Improve the safety factor in shunting operations, use equipment to more accurately use distance signals, provide effective conditions for the control of the locomotive speed of operators, and reduce the accident rate in shunting operations. The application of the radar ranging system in the shunting operation of the locomotive provides a great safety guarantee for the shunting operation, improves the safety factor in the operation, and uses the equipment to use the distance signal more accurately, and the speed of the locomotive of the operator The control provides effective conditions and reduces the accident rate in shunting operations.
