一种新型网络通信方式在监控组态软件系统中的应用

APPLICATION OF A NEW NET COMMUNICATION MODE TO THE SCADA SYSTEM

阐述了网络监控系统的一种新型网络通信方式。这种方式采用Winsock的UDP通信方式,根据需要增加返校重传功能,构建的网络通信无需建立连接,通信双方可任意退出或关闭,只要进入系统创建了通信端口,就可进行正确可靠的通信;每台计算机的网络负担相同,没有网络流量过大的网络中心,不会造成网络阻塞;网络中任意计算机或网络故障均不影响其他计算机的通信。

A new net communication mode for the SCADA system is described, in which the UDP of Winsock is used, and the verification of the data returned is added based on need. The net communication mode dispenses with connection of one program to another; both sides of communication can exit or shut down at will. Credible communication is attainable as long as the communication port is constructed. There is no center of great net communication, the burden of net communication of every computer is the same, and the net block is inexistent. Even if one computer in the net is in trouble, the communication of other computers is still in good condition.
