基于单片机的停车场车位管理系统设计(论文13000字)
摘 要
21世纪初，随着时代的变革，科技的进步，便捷的交通工具逐渐成为人们生活不可或缺的一部分。汽车的普及着实提升了我们的生活质量。随着人们生活水平的提高，汽车的数量也与日俱增。可是随之而来的问题也摆在了人们面前，那就是城市的空间越来越紧张，停车位难求，特别是到了法定假日出去自驾游，进入停车场后却发现已满，只能离开该停车场去另寻车位，给车主造成了操作麻烦，浪费了宝贵的时间。为了解决此类问题，高科技化、自动化的停车场管理系统取代了之前落后的人工管理系统，技术的革新不仅节省了大量的人力、物力、财力，而且更加方便了我们的生活，提高了生活的质量。
本论文介绍了一种停车场车位管理系统模型。系统将STC89C52RC单片机作为主控制器，用E18-D50NK红外传感器作为探测器，传感器收到信息后将数据经单片机内部传给LCD1602液晶显示屏，并连接相应的报警电路。它能人工设置停泊的车辆数量以及显示进出停车场的车辆数量。该设计不仅能直观的显示停车场的车流量，还能在车位满时发出报警。不但可方便车主了解停车场车位情况，做出适当的选择，又方便物业公司的管理。因此，对智能停车场管理系统进行深入研究具有非常重要的现实意义。

ABSTRACT
At the beginning of the 21st century, with the changes of the times, the advancement of science and technology, convenient transportation has gradually become an indispensable part of people's lives. The popularity of cars has actually improved the quality of our lives. As people's living standards improve, the number of cars is also increasing. However, the ensuing problems are also in front of the people, that is, the space in the city is getting more and more tense, and the parking space is hard to find. Especially when it comes to the statutory holiday, it is self-driving. After entering the parking lot, it is full and can only leave. The parking lot went to another parking space, causing trouble to the owner and wasting valuable time. In order to solve such problems, the high-tech and automated parking lot management system has replaced the previously backward manual management system. The technological innovation not only saves a lot of manpower, material resources and financial resources, but also facilitates our lives and improves the quality ofour lives.
This paper introduces a parking lot parking management system model. The system uses the STC89C52RC MCU as the main controller and uses the E18-D50NK infrared sensor as the detector. After receiving the information, the sensor transmits the data to the LCD1602 through the internal MCU and connects to the corresponding alarm circuit. It can manually set the number of vehicles parked and the number of vehicles that enter and exit the parking lot. The design not only visually displays the traffic flow in the parking lot, but also alerts when the parking space is full. Not only can the owner understand the parking space, make appropriate choices, and facilitate the management of the property company. Therefore, it is of great practical significance to conduct in-depth research on the intelligent parking lot management system.
