Industrial automation is a general term for information processing and process control such as measurement, manipulation, etc., achieved by machines, equipment or production processes without direct manual intervention. Automation technology is to explore and study the methods and technologies to realize the automation process. It is a comprehensive technology involving mechanical, microelectronics, computer, machine vision and other technical fields. The Industrial Revolution is the midwife of automation technology. It is precisely because of the needs of the industrial revolution that automation technology has broken its eggshell and developed vigorously. At the same time, automation technology has also promoted the progress of the industry. Nowadays, automation technology has been widely used in machinery manufacturing, electric power, construction, transportation, information technology and other fields, and has become the main means to improve labor productivity. Industrial automation is one of the important prerequisites for Germany to start Industry 4.0, mainly in the fields of mechanical manufacturing and electrical engineering. The "embedded system" widely used in German and international manufacturing at present is a special computer system designed for a specific application, which completely embeds mechanical or electrical components into the controlled device. The data shows that the annual market benefit of this "embedded system" is as high as 20 billion euros, and this figure will increase to 40 billion euros by 2020.
