Abstract: In order to meet the experimental teaching requirements of automation and other related specialties,a five-storey elevator control system is designed based on the principle of combining teaching with research,which refers to real elevator operation for teaching and scientific research.The system selects STM32 as the control unit and stepper motor as the driving unit.The elevator is lifted and lowered by the motor's forward and reverse rotation.The floor to be reached is selected by the button and displayed in real time on the digital tube.The experimental system has high reliability and low cost,and can simulate the operation of a five-storey elevator control system.On the one hand,the experimental system can help students better understand the relevant electronic knowledge in the experimental teaching of single-chip computer,on the other hand,it can also provide some reference for the research and improvement of the actual operation of elevators.
