摘要
为提高列车自动监控系统中安全相关控制命令执行结果的可靠性和安全性,满足基于车-车通信的列车自主运行系统项目安全需求,设计一种基于中央处理单元(CPU)和图形处理单元(GPU)双链计算和显示的安全控制执行结果显示方法。操作终端的C P U计算的执行结果以字符串格式输出到指定位置显示,操作终端的GPU计算的执行结果以图元格式输出到标题栏位置显示。同时采用不同编码方法、相异的算法等方式,避免同一硬件设备在编码语言、算法和硬件平台的共模失效。
In order to improve the reliability and safety of the operation results of the safety-relevant control commands of Automatic Train Supervision System,a display method for safety control operation results based on CPU and GPU double chain calculation and display is proposed to meet the safety requirements of Train Autonomous Control System based on vehicle-vehicle communication.The operation results calculated by CPU are displayed at the indicated location of the operation terminal in the character string format,and the operation results calculated by GPU are also displayed at title location of the operation terminal in the graphic format.Using different coding languages and dissimilar algorithms,this paper explores how to avoid the common mode failure on a hardware unit in terms of coding language,algorithm and hardware platform.
