停车场出入口管理系统

摘要

本论文介绍一款基于STC89C52单片机控制的停车场管理系统，它由硬件部分和软件部分组成：硬件部分主要包括红外线信号检测模块、键盘输入模块、闸门控制模块、车位状态显示模块、数码管显示模块和单片机控制中心。软件部分采用C语言编程。该管理系统可以自动控制出入口闸门的开启和关闭，具有自动计费、显示和调整北京时间、显示停车场状况等功能，而且收费的初始值以及收费标准可以自主调节，使该系统更加具有灵活性。

ABSTRACT

This paper introduces a parking management system controlled by STC89C52 single-chip microcomputer。It consists of hardware and software components：the hardware mainly includes the infrared signal detection module, the keyboard input module, gate control module, parking status display module, LED display module and MCU control center, while the software is programmed by C language。This management system can automatically control the opening and closing of the entry or exit gate，with automatic charging function，display and adjustment of Beijing time，with explicit parking status function，and the initial value and charges can independently adjust，so it make the system more flexibility。

Key Words：89C52; Monolithic machine; Parking lot; Charge for automation motor stoppage is systematic
