Design of Automatic Production Line Training System Based on PLC

Automatic production line training system is used to simulate the actual process of industrial production. According to the actual needs of teaching instrument market at present, for the purpose of students or staff training, the author designs a practical automatic production line simulation training system. Using Siemens S7-200 PLC as the control core, setting sensors, buttons and lights, power supply module, motors, pneumatic components, mechanical structures for the integration, dividing into feeding, processing, assembly, sorting, robot units, and achieving interconnection between the unit controllers via PROFIBUS. It is used to simulate the various manufacturing aspects of workpieces from raw materials to finished products in the actual industrial production lines. The system covers mechanical principles, pneumatic control technology, sensors, electrical control technology, programmable logic controller and other related knowledge points, supports professional experimental courses of automation, mechanotronics and so on. A series of practical ideas are adopted in the subject. The entire system is fully open, students can have a comprehensive view of the internal wiring situation; freely detachable, can operate under single-station or overall system; supporting secondary development, can be re-build according to the innovation requirements
