摘要
为提高列车自动监控系统人机界面的可靠性、安全性,提出一种基于安全显示的解决方案:在硬件、软件和信息等方面全面引入冗余机制。在分析安全显示需求的基础上,阐述了安全显示的关键实现技术:工作状态同步;屏幕视图截取与保存;循环冗余校验。
In order to improve the reliability and safety of man- machine interface (MMI), a solution based on safety display technique is proposed in this paper. Based on the requirements of safety display, the key technologies for the implementation of safety display are introduced, including the synchronous working state, interception and preservation of screen views and cyclic redundancy check, etc.
