How to translate DCS?

DCS ---digital control system (numeric control system) DCS --distributed control system (distributed control system) ............. This post was last edited by echommm on 2007-12-25 09:24 ]

DCS also means dichlorosilane:lol

Then the poster should judge what it is based on the context.

DCS is the abbreviation of Distributed Control System, which is generally used in China.* Usually called distributed control system. It is a multi-level computer system composed of process control level and process monitoring level and linked by communication network. It integrates 4C technologies such as computer (Computer), communication (Communication), display (CRT) and control (Control). Its basic idea is decentralized control, centralized operation, hierarchical management, flexible configuration, and convenient configuration. DCS has the following characteristics: (1) High reliability: DCS distributes the system control functions on each computer, and the system structure adopts a fault-tolerant design, so the failure of a certain computer will not cause the loss of other functions of the system. In addition, since each computer in the system has a relatively single task, special computers with specific structures and software can be used for the functions that need to be implemented, thereby improving the reliability of each computer in the system. (2) Open DCS adopts an open, standardized, modular and serialized design. Each computer in the system communicates through a local area network to realize information transmission. When the system functions need to be changed or expanded, new computers can be easily connected to the system communication network or removed from the network, with little impact on the work of other computers in the system. (3) Flexibility: Configure software and hardware according to different process application objects through configuration software, that is, determine measurement and control signals and their connection relationships, select applicable control laws from the control algorithm library, and call basic graphics from the graphics library to form various monitoring and alarm screens required, thereby conveniently constructing the required control system. (4) Easy to maintain Small or micro special-purpose computers with single functions have the characteristics of simple and convenient maintenance. When a certain part or computer fails, it can be replaced online without affecting the operation of the entire system, and the fault can be quickly eliminated. (5) Coordination: Various data are transmitted between each workstation through the communication network, and the entire system information is shared and coordinated to complete the overall function and optimization of the control system. (6) The control functions are complete and the control algorithms are rich, integrating continuous control, sequential control and batch control. It can realize advanced control such as cascade, feedforward, decoupling, adaptive and predictive control, and can easily add the required special control algorithms. The structure of DCS is very flexible. It can be composed of dedicated management computer station, operator station, engineer station, recording station, field control station and data acquisition station, etc. It can also be composed of general-purpose servers, industrial control computers and programmable controllers. The process control level at the bottom generally implements data collection and control on-site through decentralized on-site control stations, data acquisition stations, etc., and transmits it to the production monitoring level computer through the data communication network. The production monitoring level performs centralized operation and management of data from the process control level, such as various optimization calculations, statistical reports, fault diagnosis, display alarms, etc. With the development of computer technology, DCS can be connected to higher-performance computer equipment through the network as needed to achieve more advanced centralized management functions, such as planning and scheduling, warehousing management, energy management, etc.
