摘要
网络控制系统将日趋成熟的网络系统向控制领域方面延伸与扩展。集散式控制系统具有自主性、协调性、在线性、可靠性、风险分散等优势;现场总线控制系统是一种开放的分布式控制系统,是连接智能现场设备和自动化系统的数字式双向传输、多分支结构的通信网络;开放嵌入式控制网络系统具有技术支持广泛、通信速率高的特点,可以实现网络的无缝连接,但也存在网络诱导时延、数据包丢失、多包传输等方面的问题。
The networked control system is the extension of well established network system to control theory and ap- plication. Distributed control system has the advantages, such as independence, coordination, on--line, reliability, risk decentralization. Fieldbus control system is an open distributed control system and the telecommunications network, which is connected smart devices and automated systems at the two--way digital transmission, Multi--branch structure. Open embedded control network system, with the characteristics of extensive technical support and high--speed communication, can achieve seamless connectivity. But there are also network--induced delay, data packet losses, multiple--packets transmission and more such issues.
