摘　　要：实际工程应用中,C TCS-3(简称C3)级列控系统行车许可结合轨道电路信息后被截短,导致车载设备输出最大常用制动,针对该问题,简要说明C3级列控系统行车许可结合轨道电路信息的背景和主要原理,对实际工程问题进行分析。通过研究,提出对C3无线通信消息包结构以及C3车载设备获取轨道电路信息的方式进行调整的技术方案,基于该方案优化特定低频码车载处理逻辑,结合典型场景进行说明,进一步提高C3级ATP行车许可结合轨道电路信息的适应性。The paper gives a brief description of the background and main principles of movement authority(MA)used in combination with track circuit codes for CTCS-3 train control systems,which may shorten the movement authority and cause the onboard equipment to output a full service brake in the actual project.Based on the research into this problem,the paper proposes an adjustment scheme for the CTCS-3 wireless communication message structure and the way in which the onboard equipment obtains the track circuit codes.According to this scheme and the typical scenarios,the onboard processing logic for specific low-frequency coding will be optimized,which can further improve the adaptability of MA combined with track circuit codes at CTCS-3 level.
