Embodiment Construction

[0027] Such as Figure 4 As shown in , it is a structural diagram of the large-scale network control system described in the present invention, which is artificially divided into three operation domains and three control domains according to the control process or control range, which are respectively 1#, 2#, and 3# Operation domain, 1#, 2#, 3# control domain, each domain is relatively independent, each node in each domain is connected through a common switch, and intra-domain data interaction is realized through the intra-domain network. Each domain is interconnected through a multicast switch at the process control network layer to form a unified process control network, and the process control network is used to transmit all control data and real-time data.

[0028] The operation domain is a logical domain that divides the scope and authority of monitoring and the operation stations with similar process technology into the same operation domain, and can monitor multiple con...

Abstract

According to the control artwork or control range, the invention divides the process control network into several operation domains and control domains; all domains are interconnected in the process control layer through multicast exchanger to build a unified process control network; isolating each operation domain and control domain in order to make the real-time data transmission not influence the network loads of other domains; when other domains need to get the data of one domain, it can be implemented by simply configuring the operation domain.

Description

technical field [0001] The invention relates to building a large-scale automatic real-time control network with industrial control Ethernet, in particular to a large-scale network control system. Background technique [0002] Most process data networks in traditional industrial control systems use Ethernet, while process control networks that require higher reliability generally use other bus technologies. Today, Ethernet technology is more and more used in process control network due to its advantages of low cost, high speed, openness and good compatibility. [0003] In the process of applying Ethernet technology to industrial control systems, its disadvantages are gradually revealed. The main disadvantage is that when the scale of the process control network is large, the network load becomes larger, and the load of each node also increases accordingly. The real-time performance of data is seriously affected, and the data transmission is unreliable. [0004] In the curre...
