摘　　要：提出一种基于YModem协议在列车自动运行系统上的在线程序升级方法,基于Power PC系列处理器的列车自动运行系统,通过设置USB通信接口连接远程终端,适用于单板功能开发及测试、系统实验室开发及测试、现场试验等场景,利用Secure CRT远程软件,通过通用USB数据线连接主机板,实现程序下载,程序下载完成后即可执行,不需重启设备。The paper proposes an IAP used for the automatic train operation(ATO) system working with YModem protocol. By the USB communication interface on the front panel of the mainboard, such IAP applies to the Power PC series processors of ATO system. The program supports the development and testing of single-board functions and of systems in laboratory;it also applies to field tests. With SecureCRT remote software, the program is downloadable through a connection to the mainboard via the general USB cable. Once downloaded, the program can be executed immediately without restarting the device.
