Abstract
The graduation project is a hardware design of the assembly lines what based on PLC control .Programmable Logic Controller is widely used in industrial production systems, especially in the textile, electrical manufacturing industry and related industries, pharmaceutical and other industries. The system has a PLC as the core, contains high reliability, strong anti-interference ability and in the worst years of the production environment can still be quite normal to the merits of the work. At the same time, system uses a touch screen, so it has a good man-machine interface , it’s easy to operate and people don’t need a lot of professional knowledge will still be able to master its use, promoting easily. SIMATIC S7-200PLC is used in this design, there are physical, a detailed description of the details, and it can provide reference for the technology update of Industrial assembly line.
Keywords:assembly line, PLC controller, system hardware design
