摘要
在给出通信网络的消息模型后,分析了CAN总线固定优先级调度中消息传输的时间特性参数的计算及系统可调度的必要条件,论述了固定优先级调度性能分析软件的设计,给出了应用实例及总线负载率的测试结果,验证了离线分析的有效性。
Analyzing the Real-Time performance of the CAN bus is one of the focuses in applications. The model of the messages in the communication network was presented, the calculation of time characteristic parameters of the messages transmit based on Fixed-Priority Scheduling and the necessary condition of schedulability were analyzed. Then, the design of performance analysis software package was described. Finally, an application example was given and the test result of the load ratio on the bus was got, which shows that the package is a powerful offline analysis tool.
