EPA通信调度测试方法与实现技术

Test Method and Realization of EPA Communication Schedule

介绍了EPA通信协议模型和EPA通信调度规程,根据通信调度的原理和要求,研究了EPA协议确定性调度的测试原理,提出了测试EPA确定性调度的方法和系统结构,对调度偏差和调度顺序分别论述了其相应的测试流程。通过测试系统的实际应用证明这种测试方法能够准确地测试被测设备调度实体的实现与EPA标准的符合程度。

EPA communication protocol model and EPA communication schedule rule are presented. According to the principle and requirement of communication schedule, the principle of EPA protocol deterministic schedule is researched. The testing method and testing system structure of EPA deterministic schedule test are put forward. The test flow of schedule precision and schedule order are respectively presented. The practical application of deterministic schedule test system indicates the validity of this test method.
