摘要
在FF的过程控制应用中 ,为确保时间限制严格的非周期通信 ,对非周期通信带宽分配了过高的比例 ,造成通信带宽的浪费。为了提高FF通信带宽利用率 ,基于优先权机制 ,分析了FF通信的带宽分配 ,并对两种带宽分配策略进行了分析研究和性能比较。在此基础上对所得结果作进一步推广 ,给出了FF非周期通信带宽分配的优化策略。
In process control application of FF,in order to ensure that acyclic communication with critical time constraints is met,the bandwidth proportion allocated to acyclic communication is oversized,which lead to waste of bandwidth.For the sake of improving bandwidth availability of FF,based on priority mechanism,bandwidth allocation of FF is analyzed,and two bandwidth allocation strategies are researched and compared in performance.Finally,optimization strategy of FF acyclic communication is proposed based on generalization of preceding results.
