Research on Electric Locomotive Auto-passing Neutral Section

The design is to research a device of locomotive auto-passing neutral section which can test the coming of electric locomotives into Neutral Zone precisely, issue the corresponding signal to control locomotive power, detect the leaving of locomotive from the Neutral Zone, send out the corresponding signal to control the locomotive by electricity. The passing device mainly consists of the following components: catenaries, current sensors, pavement marker, device of car signal transmitting and receiving, integrated processor-vehicle of information. In such case of not changing the existing railroad facilities, with current coil mounted on catenaries, road marker, car signal receiver and transmitter and control module, combined with chip technology, sensor technology and wireless communication technology, the device can detect the accurate positions when electrical locomotive come into and leave the Neutral Zone, at the same time, control the locomotive breaker precisely . The device can increase the safety performance and improve the speed when locomotive pass the split-phase zone, and reduce the driver´s work intensity.
