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”，是工业生产尤其是流程工业的中枢和基础，其安全稳定性、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。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，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。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用DCS系统的主要原因。

传统的控制领域正经历着一场前所未有的变革，开始向网络化方向发展。控制系统的结构从最初的CCS（计算机集中控制系统），到第二代的DCS（分散控制系统），发展到现在流行的FCS（现场总线控制系统）。对诸如图像、语音信号等大数据量、高速率传输的要求，又催生了工业以太网与控制网络的结合。

Industrial automation refers to the collective name that machinery, equipment or production process can realize information processing and process control such as measurement and manipulation according to the expected goal without direct or less manual intervention. According to the function, automatic control includes control system, drive system, feedback system, execution system, motion control system, etc. The control system is called the "brain" of the factory, which is the center and foundation of industrial production, especially process industry, and its safety, stability and efficiency directly affect all production links of the production process. Traditional control systems generally include instrumentation system, DCS system, PLC system, SIS system, SCADA system, executive regulation system and so on. That is, distributed control system, which is composed of input and output module, communication module, controller and man-machine interface, is an industrial automation control system based on controller and field equipment, which collects relevant process signals into the system and is monitored or controlled by operation station, with decentralized control, centralized operation and hierarchical management as its main features. Compared with local logic control, DCS pays more attention to analog control, so DCS system has stronger data transmission and management ability, which is the main reason why DCS system is widely used in large-scale projects.

The traditional control field is undergoing an unprecedented change and is beginning to develop in the direction of networking. The structure of control system has developed from CCS (computer centralized control system) to DCS (distributed control system) of the second generation to FCS (field bus control system) which is popular now. The demand for large data volume and high-speed transmission, such as images and voice signals, has given birth to the combination of industrial Ethernet and control network.
