在计算机出现后不久,人们就在工业自动化领域找到了它的用武之地。在工业生产过程中,有各种各样反映生产过程状态的物理量,如温度、压力,电流、电压等过程信息。近年来,随着这些过程信息的数字化技术逐步发展成熟,计算机的应用领域扩展到了工业过程及生产制造领域,这就是人们常说的计算机控制系统,也就是计算机工业自动化系统。
Shortly after the advent of computers, people found its place in industrial automation. In the process of industrial production, there are various kinds of physical quantities that reflect the state of the production process, such as process information of temperature, pressure, current and voltage. In recent years, with the gradual maturity of the digitalization of these process information, the field of computer application has been extended to the field of industrial process and manufacturing. This is commonly referred to as a computer control system, that is, a computer industrial automation system.
