Elevator Simulation Operating System Based on Single Chip Microcomputer

Abstract

The design is based on STC89C52 MCU. It is based on the common cathode digital tube to achieve the elevator floor display . A plurality of light emitting diodes are used as the up and down indicator light of the elevator floor. The non self locking key is used as the key of the elevator floor. Finally the stepper motor is used to simulate the operation of the elevator. This design realize the basic functions of the elevator operation, the operator can simulate the floor by the floor button. The system can handle the requests from different floors intelligently and carry out the simulation of the elevator operation efficiently and reasonably. The design combines the usual learning of SCM knowledge and real life application tools through the MCU to achieve the elevator control. The main procedure is using the C language programming, it saves the cost of designing the hardware circuit. The new elevator will have a good market prospect.
