ign uses 89C51 microcontroller as the core, the automatic control system of the elevator with the external circuit to form. The floor buttons detection, in accordance with the procedures set out in the model, and digital tube LED regulation, so as to control the stepper motor operation to drive the elevator model to realize the up and down the elevator.This article describes the elevator key technical points of the automatic control system, system requirements analysis, system design and implementation, detailed description of the principle of the system ponents and working principle.Key words: Single Chip Microputer, Stepper Motor, Autocontrol大連東軟信息學(xué)院畢業(yè)設(shè)計(論文) 目錄III目 錄摘 要
