摘要
为了解决射频仿真计算机控制系统中多台计算机间的相对实时通讯问题 ,提出了建立小型局域网的通讯设计方案 .首先介绍了网络内部各计算机间数据流向及连接方法 ,然后制定了网络硬件及网络传输协议的选用方案 .为保证传输的相对实时性 ,在软件开发时组建软件定时器 ,为传输做精确定时 .通过对网络通讯性能的测试表明 ,通讯时间和通讯质量满足射频仿真控制系统的设计指标 .
A minitype local area network(LAN) has been made in the computer control systems for comparatively real time communication.The data stream and link method between computers of network has been introduced.Then a project for the hardware and transmission protocol of network has been set up.For comparatively real time communication in the LAN,a software timer has been created.It can provide a accurate benchmark of time.After a capability test of communication,the quality and time of communication is conformed with the target of the radio frequency simulation systems.
