多处理器系统程序自动更新和监测方法研究

Research on Automatic Updating and Monitoring Method of Multiprocessor System Program

车载ATP系统是保障列车安全、高效运行的关键设备。目前在ATP研发、测试以及后期运营维护过程中的软件更新均是采用人工操作,不仅效率低下,同时人为的干预可能造成更新软件错误和设备寿命降低。为解决上述问题,根据ATP主机硬件结构,针对二乘二取二安全系统,提出一种多处理器系统程序自动识别、更新、监测方法。该方法为有效降低软件更新过程中的安全隐患和人为操作对设备寿命的影响提供设备研发、系统设计等参考。

Automatic Train Protection is a key equipment to ensure the train operation safety and efficiency.At present, the software update of ATP in research and development, test and operating maintenance is manual operation. It is not only inefficient, but also may result in updating software errors and reducing equipment life with human interventions. In order to solve the problem, an automatic recognition, updating and monitoring method of multiprocessor system program is proposed for double 2 out of 2 safety system based on the hardware structure of the ATP. This method provides references for effectively reducing the hidden danger in software update process and the influence of manual operation on equipment life in equipment development and system design.
