EPA确定性通信与测试方法研究

EPA Deterministic Communication and Test Method Research

EPA通过采用集中调度提高实时性的方案解决了以太网确定性通信的问题,文中详细论述了EPA确定性通信的原理和调度规程,并对通信调度规程的测试方法进行了深入研究,提出了通信调度测试平台的搭建以及测试流程,并对调度顺序、非周期数据声明报文等测试案例进行了分析。

EPA solved the determinacy in Ethernet communication by adopting plan of centralized schedule to improve real-time. The principle and the scheduling regulations of communication are discussed in detail and the method of testing scheduling regulations is lucubrated. In this paper, the test platform of communication schedule and test flow are presented, and analyzed test cases of sched- ule sequence, aperiodic data statement message etc.
