摘要
报文传输可靠性对于CAN总线系统的设计十分重要,关系到总线系统的正常运行。在Tindell等专家调度理论分析的基础上针对CAN总线系统的报文传输时间进行分析,利用概率分析手段对报文传输可靠性进行研究。通过算例计算得到报文可靠度并利用MONTE-CARLO方法进行模拟对比,得到了报文的传输的可靠性。这将成为进一步计算整个CAN总线系统可靠性的基础,同时也为调度理论进一步研究提供依据,具有十分重要的实际意义。
Since the message transmission reliability for the design of CAN bus system is important, which is related to the normal operation of the bus system,the message transmission time is analyzed based on the Tindell scheduling theory,and the message transmission reliability analysis is studied by means of probability analysis.Then an example is calculated to get the message reliability,which result is contrasted with the MONTE-CARLO method to obtain the message transmission reliability;This will be the basis for calculating the reliability of the CAN bus system, and provide a foundation for the scheduling theory studies as well,which has great practical significance.
