摘要

FTT-CAN协议可以有效保证工业现场中对通信柔性的需要

但是由于干扰和错误需要后备节点信息调度表(Synchronized Regulation Table

SRT)在线更新.为此提出了一种保证异步窗口并及时处理更新请求的算法

该算法充分考虑了更高优先级的突发性信息的影响

对传统调度算法进行了优化

保证了后备节点与活动主节点的运行同步

满足了工业系统信息的实时性要求

使更新过程更加有效.

Abstract

The FTT-CAN(Flexible Timer-Triggered CAN) protocol can effectively guarantee the industrial field of the communication needs of flexibility

but due to interference and errors need Synchronous communication Requirements Table(SRT) to update online.Based on the above

an improved algorithm to guarantee the asynchronous window and timely deal with update request was presented

which fully considered the higher priority of the sudden impact of information.So the traditional scheduling algorithm had been optimized to ensure that the primary particular master/slave network and replicated masters run synchronously

to meet the industrial system requirements of real-time information and to make the update process more effective.
