| 摘 要： | 为了解决实时控制网络应用中的通讯实时性和确定性问题,提出在总线以太网上实现一种CSMA/CD-Master/Slave切换混合协议,并在其上构建UDP/IP协议,同时对该混合协议的实时性和可靠性进行计算机仿真分析.在实时控制网络应用中,当网络轻载时,采用CSMA/CD访问控制方式;当网络重载时,自动切换到Master/Slave方式,实现自动调节达到对介质的有限争用.仿真表明CSMA/CD-Master/Slave切换混合协议的应用能够提高通讯实时性和可靠性,可以保证控制网络的稳定性和实效性.

| Abstract: | In order to solve the problems of real-time communication and determinacy in real-time control network,the article put forward a kind of hybrid handoff protocol of CSMA/CD and Master/Slave according to loading variation influence real-time and certain control in the Ethernet bus control.The article also established the UDP/IP protocol on the basis of hybrid handoff protocol of CSMA/CD and Master/Slave.The result of simulation shows that the UDP/IP protocol can increase the real-time and reliability of commu... |
