中文摘要: EPA 标准是由我国提出的用于提高工业以太网实时通信性能的系统规范.在介绍EPA 通信协议模型基础上,对通信协议栈的应用层和通信调度管理实体进行了模块化设计,对协议栈的任务进行了详细划分.在设计过程中,对μclinux 系统的硬实时性和内存利用率进行了重点考虑.经实验测试,该通信协议栈可以正常工作,并取得了较理想的效果.
Abstract:EPA Standard is a system specification that was proposed by China to improve industrial ethernet real-time communication performance. On the basis of introduction of the communications protocol model, the modular design of the application layer and the communications scheduling entity of the communications protocol is described, and the task of the protocol stack is divided in detailed. In the design process, the hard real-time and memory utilization of the μclinux system are key consideration. The test results show that the communication protocol stack can work properly and it achieves better results.
