Today, the world has entered the era of automatic mechanization, automation technology and the development of electronic computers are rapidly increasing the degree of automation of production processes. Realize the production process from work, can improve the yield, quality assurance. Reduce raw material and can skip the elimination round. At first glance, to decrease the cost of production, improve labor conditions. To ensure safety in production, reduce environmental pollution. Received good economic benefits and social benefits, the production process automation become the main trend of modern technology.
With the development of production and science and technology, the concept of automation and memory are different. Early. Automation refers to the use of machines and other machines to replace human manual labor, that is, mechanical, and later. Due to the development of production, machinery and equipment, the increase in the number of people to control machinery and equipment of the task. In order to reduce the burden of machinery and equipment, people developed automatic control device to control the machine and production of weighing in time to use feedback technology of machinery and equipment for automatic control called automation. Since 1960s, people began to use electronic computer to control and manage the production process and other processes, which is not only to reduce the manual labor, but also to reduce or replace human mental labor, that is to realize the automation of information processing. Therefore, automation is a study of the production process and other processes using a mechanical device (instrument, electronic computer, etc.) to automatically control and information processing, in order to extend and expand the human organ function of the integrated science and technology.
In the machinery industry, although automation is a trend, but regardless of how the development of the automation technology, it is extension of the organ and strengthen and replaces all the generation of physical labor and mental labor.
