摘要
对前端处理器在轨道交通综合监控系统中的应用进行研究,详细讨论功能需求、数据流向、工作流程以及前端处理器的冗余工作机制。在分析应用现状的基础上,对前端处理器的软硬件可靠性、数据传输性能、冗余方案进行优化研究。
The paper studies the application of FEP (From End Processor) in integrated supervisory control system of rail transit and analyses the functional requirements, data flows and redundancy mechanism in detail. On the basis of applied researches, software and hardware reliability, data transmission performance, redundancy program were optimized.
