摘　　要：在CTCS3-300T型列控车载设备中,单电台故障是导致车载侧无线通信超时的主要原因。通过分析电台实际运行数据,发现电台V2.3.31版软件存在复位不彻底问题;提出通过电台内部看门狗芯片进行电台硬复位的优化建议。软件版本升级后的运行结果表明:电台硬复位功能实际运用效果良好。In CTCS3-300T train control on-board equipment,the single mobile terminal fault is the main reason for the timeout of wireless communication on the on-board side.Through the analysis of the actual operation data of the mobile terminal,it is found that the software version V2.3.31 of the mobile terminal is not completely reset.Therefore,the optimization suggestions of the hard reset of the mobile terminal through the watchdog chip inside the mobile terminal are put forward.After the software is upgraded,the results show that the hard reset function of the mobile terminal has achieved good practical application results.
