This can avoid some people cannot contact material harm to human body, such as metallurgy, chemical, pharmaceutical, aerospace and other. The manipulator on the domestic and foreign research level is not a, but represent the most advanced technology in Japan, his automation, humanity is as the acme of perfection, these techniques rely on control theory, new material science, it is the integration of a variety of cuttingedge technology and modern machines. Our country also gradually in the industry has been applied, for automatic control, flexible manufacturing system in the application of more extensive, but China39。 the shielding measures to prevent space electromagic interference。s guidance and my own efforts I can very good plete the design tasks, although period must be encountered such or in that way difficult, but I have confidence in doing all this. Any control system goes through four stages from conception to a working plant. A PLC system brings advantages at each stage. The first stage is design。 has the advantages of small volume, light weight, convenient installation. Because PLC has such a series of advantages, in the industrial control is widely used in the following three kinds of control: ( 1) switch quantity sequence, logic control. In the place of the relay control system, such as the metallurgical industry in the charging system of blast furnace, rolling mill, continuous casting machine, fee shear control system。s economic strength and scientific and technological level of an important symbol. Therefore, all countries in the world the development of machinery industry as national economy development strategic point of ( Zhang Zhixian, 2020). The new century, the level of production and the continuous progress of science and technology and development to the entire machinery industry39。 set filter links, to eliminate the external interference and the interference effects between each module。 the required plant is studied and the control strategies decided. With conventional systems design must be plete before construction can start. With a PLC system all that is needed is a possibly vague idea of the size of the machine and the I/O requirements (how many inputs and outputs). The input and output ca
