目前，农业、工业、生活、军事等各个方面都向自动化、智能化、数字化发展。为了适应时代的发展，电子技术发展迅猛。自动化、智能化、数字化的实现方式多种多样，从而产生了很多设计工具。单片机就是其中之一，它正朝着高性能和多品种方向发展，正进一步向着CMOS化、低功耗、小体积、大容量、高性能、低价格和外围电路内装化等几个方面发展。卓越的性价比受到了设计者们的欢迎。
随着汽车的普及，停车场的数量越来越多，传统的人工管理的停车场需要耗费大量的人力和财力。智能停车场系统为了保证车辆安全和交通方便，迫切需要采用自动化程度高、方便快捷的停车场自动管理系统，提高停车场管理水平。现阶段的目标就是要提供满足人们工作、生活、娱乐环境更科学、规范、快捷有效、安全、方便的智能停车场自动管理系统。停车场管理系统正在向大型化、复杂化、集成化和高科技化方向发展，智能停车场系统已经被纳入智能建筑的一个重要子系统，并且正与智能建筑等其它子系统进一步高度集成。
单片机是微机的一个分支，在原理和结构上，单片机与微型机之间不但没有根本性的差别，而且微型机的许多技术与特点都被单片机继承下来了。
AT89S52是一种低功耗、高性能CMOS 8位微控制器。使用Atmel公司高密度非易失性存储器技术制造，与工业89C51产品指令和引脚完全兼容。片上Flash允许程序存储器系统可编程，亦适于常规编程器。在单片机芯片上，拥有灵巧的8位CPU和可编程Flash，使得AT89S52为众多嵌入式控制应用系统提供高灵活、超有效的解决方案。它具有串行口，片内晶振及时钟电路。另外，AT89S52可降至0Hz 静态逻辑操作，支持2种软件可选择节电模式。空闲模式下，CPU停止工作，允许RAM、定时器/计数器、串口、中断继续工作。掉电保护方式下，RAM内容被保存，振荡器被冻结，单片机一切工作停止，直到下一个中断或硬件复位为止。
单片机的程序设计有其自身的特点。在单片机系统中，硬件与软件紧密结合，由于硬件电路的设计不具有通用性，所以必须根据具体的硬件电路来设计对应的软件，硬件设计的优劣直接影响到软件设计的难易，软件设计的优劣又直接影响到硬件的发挥。在很多时候，软件可以替代硬件的功能，当然，需要付出额外占用CPU时间的代价。
软件程序的设计是根据硬件电路图的连接和各个元器件的功能进行设计。在编写软件时，可以按各个程序的功能将软件细分为各个功能模块，再通过主程序的调用来实现整个软件系统。而一般编写的程序都是根据事前所用的流程图来编写的，而且，流程图中也包含了对设计所得结果的要求，因此，流程图的设计直接影响到源程序的设计。
单片机芯片作为控制系统的核心部件，具有强大的逻辑功能、4个IO口，5个中断系统，配合外围硬件，使系统的功能最大化、最优化。单片机芯片通过传感器模块检测到有车辆进出时，进行一系列的推理判断，控制门的开启。单片机芯片对显示模块进行动态扫描，显示当前停车场内车辆的数目及状态。当进入停车场内的车辆数目达到最大值时，门会自动关闭，并让寻找进人停车场入口的车辆了解车位状态。在程序中判断进入的是车辆还是人，如果是人则自动门开启，停车位不进行加减。另外，本系统设置了控制部分，可以人工的设置总车位数，剩余车位数，使本系统无论安装在哪个停车场都能适用。

At present, agriculture, industry, life, military and other aspects to the automatic and intelligent, digitalization development. In order to adapt to the development of The Times, the electronic technology is developing rapidly. Automatic and intelligent, digital realization ways, thus generating a lot of design tools. SCM is one of them, it is moving toward high-performance and many varieties direction, are further toward CMOS change, low power consumption, small volume, high capacity, high performance, low price and peripheral circuit inside outfit change from several aspects such as development. Excellent cost-performance by the designer's welcome.

With the popularization of car parking lot, increasing number of traditional manual administration of parking need to spend a lot of manpower and wealth. Intelligent parking system in order to ensure the safety and convenient transportation, the urgent need to adopt a high degree of automation, fast and convenient parking automatic management system, improve the parking management level. At present the aim is to provide satisfy people work, life and entertainment environment more scientific, standardized, efficient, safe and convenient intelligent parking automatic management system. Parking management system is to the large-scale and complication, integration and high tech direction, intelligent parking system have been incorporated in intelligent building an important subsystems, and working with intelligent building and other subsystems further highly integrated.

Single-chip microcomputer is a branch of, in principle and structure, single-chip microcontroller and fundamental difference between not only, and many of the single-chip microcontroller technology and features are inherited.

AT89S52 devices is a low-power, high-performance CMOS 8-bit microcontrollers. Use high-density Atmel company the beltpassword nonvolatile storage technology and manufacturing, and industrial 89C51 product instructions and pin fully compatible. Chip Flash allow program memory system programmable, also suitable for conventional programmer. The single-chip microcomputer chip, have dexterous 8 bits CPU and programmable Flash, make AT89S52 for many embedded control application system provides the high flexible, super efficient solution. It has a serial port, piece inside crystals timely clock circuit. In addition, 0Hz AT89S52 can drop to static logic operation, support two software can choose power saving mode. Idle mode, the CPU to stop working, allowing the RAM, timer/counter, serial ports, interruption continue to work. Power lost protection mode, RAM content being saved, has been frozen, microcontroller all work stop, until the next interruption or hardware reset so far.

Microcontroller programming has its own characteristics. In the SCM system, hardware and software closely, because hardware circuit design does not versatile, so must according to specific hardware circuit to design the corresponding software, hardware design quality directly affect the software design, the ease of software design quality and directly affect the hardware of the play. In many cases, the software can replace hardware function, of course, need to pay extra occupy CPU time price.

Software program is designed according to hardware circuit connection and the function of each component design. In coding software, can press each program function will software subdivision for modules, again through the main program tend to make the whole software systems. While general program are based on prior used to write, and flow chart, flow charts, also includes results of design requirements, so, flow charts, design directly affect the source program design.

Single-chip microcomputer chip as core components of the control system has strong logic function, four IO mouth, 5 interrupt system, cooperate the peripheral hardware, make the function of the system maximization, optimization. Single-chip microcomputer chip through the sensor module detects mantainence access, carries on a series of reasoning judgment, control the door open. Single-chip microcomputer chip to display module dynamically scan, display the current carpark the number of automobiles and state. When entering the parking lot reach a maximum number of vehicles, the door would automatically shut off, and make finding into a car park entrance vehicles understand parking state. In a program in judgment entered is vehicles or, if is automatic door open, parking space is not to add and subtract. Besides, this system has set up control section, you can manually set total parking number, remaining parking number, make this system no matter which can be installed in the parking lot applicable.
