Abstract: In order to improve the experimental teaching effect of programmable logic control system, based on the elevator simulation model of "Siemens Cup" China Intelligent Manufacturing Challenge, taking the five-story elevator for teaching as the controlled object, replacing the electrical control system of the original teaching elevator, adopting Siemens S7-1200 series programmable controller, frequency converter and touch screen, and configuring hardware system terminals, a new elevator teaching and training platform is developed, and a new experimental teaching mode of "virtual-real" combination is established. And the modular idea is introduced into the system design, which makes it easy to adjust the training content, so that students can learn the relevant course content from easy to difficult. From virtual simulation to practical operation, this training platform stimulates students' interest in learning and plays an active role in cultivating students' professional quality.
