industrial automation编辑历史

Industrial automation is the use of control systems, such as computers, robots, and information technologies, to handle industrial processes and machinery, replacing human intervention in tasks that are repetitive, dangerous, or require high precision. It encompasses a wide range of technologies, from simple programmable logic controllers (PLCs) to complex cyber-physical systems and the Industrial Internet of Things (IIoT). The primary goals are to increase productivity, improve quality, enhance safety, and reduce costs in manufacturing and other industrial sectors.

## 1 History

### 1.1 Early mechanization and the Industrial Revolution

The roots of industrial automation lie in the mechanization of production during the 18th and 19th centuries. Water and steam power replaced manual labor in textile mills, ironworks, and other industries. Simple mechanical linkages and cams allowed repetitive tasks—such as weaving or stamping—to be performed with greater consistency. These early machines laid the groundwork for later automated systems by demonstrating that processes could be standardized and controlled through mechanical means.

### 1.2 Introduction of mass production and assembly lines

In the early 20th century, the concept of mass production was pioneered by manufacturers such as Henry Ford. The moving assembly line divided complex products into a sequence of simple operations, each performed at a fixed station. This greatly increased throughput while reducing the skill required of individual workers. Although human operators still performed most tasks, the assembly line’s rigid sequencing and specialized tooling represented an early form of procedural automation.

### 1.3 Advent of electronic controls and PLCs

The development of solid-state electronics in the mid-20th century opened new possibilities for automation. In 1968 the first programmable logic controller (PLC) was developed as a replacement for hardwired relay logic systems. PLCs could be reprog
