摘要
针对某种伺服系统网络通信需要,设计出基于Vxworks实时系统与多路DSP网络通讯方案。分析了伺服系统中网络通讯特点,提出了一种多播通讯报文来解决报文接收同步问题,给出了网络通信中周期发送任务程序设计框架,同时由DSP网络通信的需求,外扩了以太网控制芯片RTL8019AS,并详细分析了软件设计过程。
To meet the need of network communication of certain servo system, the network communication programs based on Vxworks and multiple DSP are designed. Analyzing the features of the network communications of the servo system, a kind of multicast package to solve synchronization problems of transmitting program in network communication are put forword, besides package received and the deisgn frame for periodic , in order to meet the requirements of DSP network communication, out-extend ether net control chip RTL8019AS and elaborate the process of software design.
