Design and Simulation of elevator controller based on 80C51 single chip microcomputer

Abstract: This topic based on the AT80C51 microcomputer, the use of C keil language design of the elevator controller, and in the Proteus PC platform to do functional simulation. The main function of the system: inside the elevator floor buttons and stairs on each floor of the mouth on the right operation keys; inside and outside the elevator elevator running direction indicator to show the correct; elevator correct response on each floor of the ladder command and inside the elevator floor button command called. First of all, the analysis of the core content of the elevator controller: 51 MCU and stepper motor familiar and analysis; Then the modules of the system are classified: can be pided into hardware design, software design, circuit simulation and Proteus platform simulation debugging; then segment each module. In the code realize the function of each module. Finally, a complete code and circuit diagram are designed and the basic functions of the system are realized on the simulation platform. The key point of this paper is the circuit design and elevator simulation operation and motor control, the motor control problem is solved mainly by using the interrupt circuit to control the response of the elevator and motor drive.
