摘　　要：以带中岔股道的车站为例,车站采用25 Hz轨道电路叠加ZPW-2000A电码化,正线和侧线都采用预叠加发码方式,明确了电码化设计范围和设计原则;分析了长进路发码电路、正线和侧线传输电路的原理;对比常规设计电路,提出了解决方案,为今后其他项目的设计提供参考。In the case of the track with a switch where the station adopts 25 Hz track circuit overlapped with ZPW-2000A code and both the main track and the sidings adopt pre-overlapped code mode,the scope and principle of coded design are clarified.The principle of the code sending circuit for the long-route as well as the transmitting circuits of the main track and sidings are analyzed.In Contrast with the conventional design of coding circuit,a solution is proposed as reference for the design of other projects in the future.
