UFC718AE01 HIEE300936R0101工業(yè)自動化是指機器設(shè)備或生產(chǎn)過程在不需要人工直接干預(yù)或較少干預(yù)的情況下，按預(yù)期的目標(biāo)實現(xiàn)測量、操縱

等信息處理和過程控制的統(tǒng)稱。按功能劃分，自動化控制具體包括控制系統(tǒng)、驅(qū)動系統(tǒng)、反饋系統(tǒng)、執(zhí)行系統(tǒng)、運動控制系統(tǒng)等，其中的控制系統(tǒng)被

稱為是工廠的”大腦”，工業(yè)生產(chǎn)尤其是流程工業(yè)的中樞和基礎(chǔ)，安全穩(wěn)定性、效率性直接影響生產(chǎn)流程各個生產(chǎn)環(huán)節(jié)。傳統(tǒng)控制系統(tǒng)一般包括

儀器儀表系統(tǒng)、DCS系統(tǒng)、 PLC系統(tǒng)、SIS系統(tǒng)、 SCADA系統(tǒng)、 執(zhí)行調(diào)節(jié)系統(tǒng)等。

DCS,即集散控制系統(tǒng)，由輸入輸出模塊、通信模塊、控制器和人機界面組成，UFC718AE01 HIEE300936R0101是一 種以控制器和現(xiàn)場設(shè)備為基

礎(chǔ)，將相關(guān)工藝信號匯集到系統(tǒng)中，由操作站進(jìn)行監(jiān)視或其他控制操作，以分散控制、集中操作、分級管理為主要特征的工業(yè)自動化控制系統(tǒng)。

UFC718AE01 HIEE300936R0101與PLC側(cè)重于局部邏輯控制相比，DCS更注重模擬量的控制，因此DCS系統(tǒng)擁有更強的數(shù)據(jù)傳輸和管理能力，這也

是大型項目廣泛應(yīng)田DCS系統(tǒng)的主要原因

控制系統(tǒng)已被廣泛應(yīng)用于人類社會的各個領(lǐng)域。在工業(yè)方面，對于冶金、化工、機械制造等生產(chǎn)過程中遇到的各種物理量，包括溫度、流量、壓力、厚度、張力、速度、位置、頻率、相位等，都有相應(yīng)的控制系統(tǒng)。在此基礎(chǔ)上通過采用數(shù)字計算機還建立起了控制性能更好和自動化程度更高的數(shù)字控制系統(tǒng)，以及具有控制與管理雙重功能的過程控制系統(tǒng)。在農(nóng)業(yè)方面的應(yīng)用包括水位自動控制系統(tǒng)、農(nóng)業(yè)機械的自動操作系統(tǒng)等。

UFC718AE01 HIEE300936R0101 Industrial automation refers to the machine equipment or production process in the case of no direct manual intervention or less intervention, according to the intended goal to achieve measurement, manipulation

Information processing and process control. According to the function division, the automatic control includes the control system, the drive system, the feedback system, the execution system, the motion control system, etc., in which the control system is

Known as the “brain” of the factory, industrial production, especially the center and basis of the process industry, safety, stability, efficiency directly affect the production process of each production link. Traditional control systems generally include

Instrumentation system, DCS system, PLC system, SIS system, SCADA system, executive regulation system, etc.

DCS, that is, distributed control system, consists of input and output module, communication module, controller and human-machine interface, UFC718AE01 HIEE300936R0101 is a controller and field equipment based

The relevant process signals are gathered into the system, monitored or other control operations are carried out by the operation station, and the industrial automation control system is mainly characterized by decentralized control, centralized operation, and hierarchical management.

UFC718AE01 HIEE300936R0101 Compared with PLC focusing on local logic control, DCS pays more attention to analog control, so DCS system has stronger data transmission and management capabilities, which also

It is the main reason for the extensive application of DCS systems in large-scale projects

Control systems have been widely used in various fields of human society. In industry, there are corresponding control systems for various physical quantities encountered in the production process of metallurgy, chemical industry, machinery manufacturing, including temperature, flow rate, pressure, thickness, tension, speed, position, frequency, phase, etc. On this basis, a digital control system with better control performance and higher degree of automation, and a process control system with dual functions of control and management have been established by using digital computer. Applications in agriculture include automatic water level control system, automatic operating system of agricultural machinery, etc.
