What industrial control system? Industrial control system is a generic term used to describe different types of control systems and associated equipment, including devices, systems, networks, and for controlling operation of an industrial process or automation. Common are: monitoring and data acquisition, distributed control systems, industrial automation and control systems, remote terminal device, a control server or the like. Industrial control system architecture generally represents a graphical manner, i.e., an industrial control system of FIG.
Common industrial control system introduced
Industrial control systems is the general term for various types of control systems, currently common industrial control systems are:
Monitoring and data acquisition system: Abbreviation the SCADA;
Distributed Control System: Abbreviation the DCS;
Process control system, the PCS abbreviation;
PLC, the PLC abbreviation;
Remote terminal unit, abbreviated RTU;
Wherein the PLC and the device used to acquire the RTU form, PLC equipment can be used for local control, DCS is generally used for the overall control of the production process of the LAN, SCADA mainly collect monitoring data from the PLC and the RTU.
With the computer, the development of network communications and sensor technology, data acquisition and supervisory control system (abbreviation: SCADA, Supervisory Control And Data Acquisition) applications more widely, it is a computer-based DCS and power automation control systems, which are widely used in data acquisition and supervisory control and process control and other areas of the field power, metallurgy, petrochemical, chemical, gas, railways and the like. "Four remotes" .RTU (Remote Terminal Unit), FTUs (FTUs) The system can implement various functions of data acquisition, control equipment, measuring, regulating and various parameters like alarm signal, i.e., as we know it is important parts of.
Range of applications in industrial control systems from small laboratory to large factories to data monitoring and remote control of cross-boundary. For every application areas, throughout the life cycle process control system includes: from planning, creation and configuration of equipment, commissioning and operation. To achieve the overall seamless integration and intuitive operation reduces installation time, ensure that the machine and the system has high productivity, we need well-designed industrial control systems, including systems design drawing, construction and operating instructions.
Simple industrial control systems Drawing Method
Here to Figure billion illustrated , for example, to map template picture shows the basic engineering of industrial control systems to create a project, select 1 standard page template Figure billion shown. Referring to FIG 4 select a common electrical symbols library, using two common electrical components category icon, and FIG. 3 commonly used alarms and access icon, the electrical wiring by combining a plurality of elements, industrial control systems required for formation of FIG.
