Westinghouse DCS system description:

DCS is abbreviation of Distributed Control System, which is called Distributed Control System in ‘s domestic automatic control industry. It is a multi-level computer system composed of process control level and process monitoring level as the link of communication network. It integrates computer Computer, Communication, CRT and Control 4C technology. The so-called distributed control system, or in some information called the distributed system, is a new type of computer control system relative to the centralized control system, which is based on the centralized control system developed, evolved Come on. It is a multi-level computer system composed of process control level and process monitoring level with communication network as the link, which integrates 4C technology such as computer, communication, display and control. Its basic idea is decentralized control, centralized operation, hierarchical management, Configuration flexibility and configuration convenience. In terms of system functions, DCS and centralized control system is not very different, but in the realization of system functions are completely different, first of all, DCS skeleton – system network, which is the basis and core DCS. As the network for the DCS real-time system as a whole, reliability and scalability, plays a decisive role, so all manufacturers are carefully designed in this regard. For the DCS system network, it must meet the real-time requirements, that is, within a certain time limit to complete the transfer of information. The “definite” time limit here means that in any case, the transmission of information can be completed within this time limit, which is determined according to the real-time requirements of the controlled process. Therefore, the indicator that measures the performance of the system network is not the rate of the network, commonly referred to as the number of bits per second (bps), but the real-time nature of the system network, that is, how long to ensure that the required information is transmitted . The system network must also be very reliable, in any case, network communication can not be interrupted, so most manufacturers are DCS dual-bus, ring or dual star network topology. In order to meet the requirements of system expansion, the maximum number of nodes that can be accessed on the system network should be several times larger than the actual number of nodes. In this way, on the one hand, new nodes can be added at any time, and on the other hand, the system network can be operated at a light communication load to ensure the real-time and reliability of the system. In actual operation of the system, the access to and access to the Internet at various nodes may happen at any time, especially the operator station. In this way, the network reconfiguration will be carried out frequently, and this operation absolutely can not affect the normal operation of the system. Therefore, the system The network should have strong online network reconfiguration capabilities.
