汽车是现代社会出行的必需品，也是科技发展的创新物。汽车的广泛使用也使停

Automobiles are a necessity for travel in modern society and an innovation in the development of science and technology. The widespread use of cars has also made parking a global public problem in modern society. Based on the investigation and research on the charging and parking timing of vehicles entering and leaving the parking lot. This paper introduces an intelligent parking system design based on STC89C52 microcontroller, the main control chip is used for billing system and vehicle detection. The system detects the vehicle through sensors, and the owner uses a card swiping method to let the lifting rod automatically take off and land, and processes the information through the microcontroller and outputs it using a liquid crystal display. Specific functions include the display of parking time and costs, and understanding of the parking spaces in the parking lot. The design system has the following characteristics: no supervision, fast speed and high efficiency; reduced investment in human resources. Scientific and efficient, simplified vehicle management procedures, safe and reliable.

汽车是现代社会出行的必需品，也是科技发展的创新物。汽车的广泛使用也使停车成为现代社会的全球性公共问题。基于对车辆进出停车场收费和停车计时的调查和研究。本论文介绍了一种智能停车系统设计基于STC89C52微控制器，主控芯片用于计费系统和车辆检测。该系统通过传感器检测车辆，车主进行刷卡方式让升降杆自动起降，通过微控制器处理信息并使用液晶显示的方式输出。具体的功能有停车时长和费用的显示、了解停车场内的车位空余等。该设计系统具有以下特点：无需监管，速度快，效率高；减少了人力资源的投入。科学高效，简化车辆管理程序，安全可靠。

Automobile is not only the necessity of travel in modern society, but also the innovation of science and technology development. The widespread use of cars also makes parking a global public problem in modern society. Based on the investigation and Research on the charging and parking time of vehicles entering and leaving the parking lot. This paper introduces an intelligent parking system design based on STC89C52 microcontroller. The main control chip is used for billing system and vehicle detection. The system detects the vehicle by sensors, the car owner swipes the card to let the lifter take off and land automatically, and the information is processed by microcontroller and output by LCD. The specific functions include the display of parking time and cost, understanding of parking space vacancy in the parking lot, etc. The design system has the following characteristics: no need of supervision, fast speed, high efficiency; reduce the input of human resources. Scientific and efficient, simplified vehicle management procedures, safe and reliable.<br>
