摘要
鉴于目前计算机局部网(LAN)产品的实时、分布性能难于有效地支持工业数据采集及监控系统(SCADA)的事实,本文提出并部分实现了一种具有分布、实时性能的LAN——U—NET。讨论了CSMA/CD的实时性,以及实时LAN的通讯规约和NOS的有关技术问题。
Seeing that the LAN products at present are lack of the functions of the real—time control and distribution so that it can't be used in the industrial system efficiently, we give in this paper a design of a type of LAN——U—NET,which has real—time performance and distributed functions. And we also do some research about the real—time performance of CSMA/CD, the real—time LAN communication and some key problems about NOS.
