摘要随着经济、科技的飞快发展，社会在不断进步，交通工具是越来越普及。而且跟着人们的生活水平的不断提高，汽车的数目也是一日一日的俱增。现在，我们随处可见我们的周围都是小汽车。尤其是过马路的时候，汽车一辆接着一辆，我们根本没法过去，要等很长的时间，这无疑是增加了我们的烦恼。而且停车也是一个问题，有的车直接停在马路边，严重影响了路人的行走，所以停车的问题逐渐成为世界性的问题。而且以前的停车场都是以人力来管理的，这浪费的大量的人力和资源，所以使停车场自动化是一种发展趋势。70312
本论文介绍了一种基于单片机的停车场车位自动监控管理系统模型。它可以在任何一段时间内，只要有司机来停车，就能够看到是否还有空余的停车位，使车辆进去。它还能够显示是否有空余车位，空余车位有多少个，是否还能够停车以及是否有车辆进、出停车场。本文设计应用的是由单片机AT89C51芯片实现停车场车位的监控显示，利用串行口通信，另外加上74LS164扩展芯片。由单片机AT89C51芯片的两个中断来实现灯的闪烁和紧急情况的中断以及清除紧急情况的中断。车位显示是由两个共阳极的七段数码管显示的，另外加上74LS164来实现数码管的静态显示，检测的元件是用按钮开关来代替的。

Design of automatic monitoring system for parking lots based on single chip microcomputer
Abstract With the rapid development of economy, science and technology, society progresses,transportation is becoming more and more popular .And with the continuous improvement of people's living standards, the number of cars is also a day of the increase. Now, we can see that we are surrounded by cars.Especially when crossing the road,the car one after another,we have no law in the past, have to wait a long time, which undoubtedly adds to our troubles. And parking is also a problem, and some cars parked directly on the road side, a serious impact on the pedestrian walk, so the problem of parking is becoming a worldwide problem.And before the parking lot are managed by human, which wasted a lot of manpower and resources, so making parking automation is a trend.
This paper introduces a kind of automatic monitoring and management system model based on single chip microcomputer. It can be at any time, as long as the driver to park the car, you can see whether there is a spare parking space, the vehicle inside.It is also able to show whether there are spare parking spaces, how many free parking spaces, whether it is also able to stop and whether the vehicle into the parking lot.The subject application is designed to be implemented by the microcontroller AT89C51 chip monitor display parking spaces, using the serial port communication, plus the 74LS164 expansion chip.Two interrupt by the microcontroller AT89C51 chip to achieve the lights flashing and the emergency situation and the interruption of emergency clearance. Parking is displayed by the two common anode seven-segment LED display, plus 74LS164 to achieve the static display of digital control.The detecting element is replaced by a button switch.
