多功能车辆总线周期信息实时调度算法的研究与实现

摘要

在不改变周期信息本身的前提下,对MVB(多功能车辆总线)周期信息的实时通信调度做了深入的研究,提出了实时调度算法,并编制了调度表生成程序.采用列表驱动算法与RM(单调比率)算法结合的方式,结合MVB通信特征,实现了MVB实时调度表的建立,并对调度算法进行了可调度性分析,确保了MVB周期信息实时调度表的有效性.根据调度算法,编写了MVB周期信息实时调度程序,获得了与Duagon公司的MVB调度表生成程序D2000相一致的结果,进一步验证了调度算法的正确性.%By referring to MVB communication features,an algorithm is proposed,mixed by table-driving algorithm and RM algorithm. With this algorithm, the approach to the real-time schedule table for MVB is also introduced, the feasibility is guaranteed without any test. Furthermore, a MVB real-time scheduling software is created and the application of this software is compared with the MVB scheduling software of Duagon Company,in order to verify the correctness of this algorithm.
