摘要
Abstract
Track circuit is one of the very important equipment in the railway signal system. The failure of track circuit will affect the traffic safety. Bad shunt of track circuit is a common fault in railway signal system, and the high-voltage asymmetric pulse (HVAP) track circuit is an effective solution to it. However, there are some shortcomings in the current equipment such as line attenuation, need compensation, expensive cost, and so on. A network-based track circuit receiver solution is proposed. The characteristic parameters of high-voltage asymmetric pulse are extracted directly in the outdoor, and sent to indoor devices through CAN. Field test data show that the new receiver meets the design requirements, and can work reliably.关键词
