摘　　要：无线通信超时是铁路信号故障整治的重点和难点,中国国家铁路集团有限公司联合各铁路局集团公司、通信信号厂商开展专项整治以来,无线通信超时情况虽降幅显著,但在铁路信号故障中仍占有较大比例。结合无线通信超时整治工作,以几种典型车地无线通信协议引起的无线通信超时为例,对无线通信超时发生的原因进行专项剖析,明确了车载ATP和地面RBC设备在协议处理中不合理之处,并在深入研究无线通信协议规范的基础上,提出了相关优化建议,为完善无线通信协议、减少无线通信超时问题提供方案和思路。Radio communication timeout is the key and difficult point in the renovation of railway signal faults.Since China State Railway Group Co., Ltd. implemented the special renovation campaign with its regional groups and communication and signal manufacturers, the number of timeout faults greatly decreased, still accounting for a large proportion. According to the renovation work of radio communication timeout, special analysis is carried out on the causes of radio communication timeout by taking several kinds of typical radio communication timeout caused by onboard-trackside radio communication protocol as an example. The unreasonableness of onboard ATP and trackside RBC equipment in protocol processing is identified, and on the basis of in-depth study of radio communication protocol specifications, some optimization suggestions are proposed, so as to provide solutions and ideas for improving radio communication protocols and reducing radio communication timeout faults.
