摘要: 分析RM、EDF、MEFTOD经典实时调度算法的不足。针对实际网络监控系统中通信对象的特点,结合CAN总线协议,设计一种混合调度算法。利用TrueTime工具箱建立网络监控系统模型,对算法进行仿真、分析,证明了该算法的有效性和优良性。

Abstract: The insufficient of realtime classic scheduling algorithms including RM, EDF and MEFTOD is analysed. Considering the characteristics of the communication objects in actual networked supervisory control system, a hybrid scheduling algorithm in combination with CANbus protocol is designed. The model of networked supervisory control system is established by using TrueTime toolbox, through which the algorithm is simulated and analysed, and the effectiveness of the algorithm is proved.

Key words: CAN-bus, networked supervisory control system, hybrid scheduling algorithm, TrueTime
