UFC718AE01 集散控制系统

UFC718AE01 HIEE300936R0101工业自动化是指机器设备或生产过程在不需要人工直接干预或较少干预的情况下，按预期的目标实现测量、操纵

等信息处理和过程控制的统称。按功能划分，自动化控制具体包括控制系统、驱动系统、反馈系统、执行系统、运动控制系统等，其中的控制系统被

称为是工厂的”大脑”，工业生产尤其是流程工业的中枢和基础，安全稳定性、效率性直接影响生产流程各个生产环节。传统控制系统一般包括

仪器仪表系统、DCS系统、 PLC系统、SIS系统、 SCADA系统、 执行调节系统等。

DCS,即集散控制系统，由输入输出模块、通信模块、控制器和人机界面组成，UFC718AE01 HIEE300936R0101是一 种以控制器和现场设备为基

础，将相关工艺信号汇集到系统中，由操作站进行监视或其他控制操作，以分散控制、集中操作、分级管理为主要特征的工业自动化控制系统。

UFC718AE01 HIEE300936R0101与PLC侧重于局部逻辑控制相比，DCS更注重模拟量的控制，因此DCS系统拥有更强的数据传输和管理能力，这也

是大型项目广泛应田DCS系统的主要原因

控制系统已被广泛应用于人类社会的各个领域。在工业方面，对于冶金、化工、机械制造等生产过程中遇到的各种物理量，包括温度、流量、压力、厚度、张力、速度、位置、频率、相位等，都有相应的控制系统。在此基础上通过采用数字计算机还建立起了控制性能更好和自动化程度更高的数字控制系统，以及具有控制与管理双重功能的过程控制系统。在农业方面的应用包括水位自动控制系统、农业机械的自动操作系统等。

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.
