摘要
目前随着计算机物联网技术的发展，停车场也将智能化，运用RFID标签识别技术，实现身份验证，停车收费；目前在我们周围出现不少RFID智能停车场，经过实地考察和查看网上资料显示，其基本功能为：刷卡识别，打开门禁，进行计时或计次收费。卡片分会员卡和临时卡两种。为处理突发故障，必须人工监管。基于现状，我设计了一套RFID智能停车场管理系统，增加了手机客户端支付、远程控制门禁、视频监测和停车位检测推荐功能。
本设计基于RFID综合平台，硬件采用基于Samsung公司最新的S5PV210 嵌入式微处理器。S5PV210 属于32位的精简指令集微处理器，被广泛应用于移动终端和便携设备的开发，性价比极高。其集成了 ARM 的 Cortex-A8 核。运用了平台提供的UHF-900M超高频读卡器模块、高速闸机控制器模块、电子锁控制器模块和门禁闸机控制器模块，外加STM32单片机，dht11温湿度传感器，烟雾传感器模块，红外循迹模块和超声波模块。软件设计分为基于QT的平台软件设计和基于JAVA的网页设计以及手机终端APP设计。
本系统分为四部分：ARM平台端、环境检测端、PC端和手机端，四者之间通过socket通信。ARM平台端通过A8网关处理刷卡或手机客户端信息，控制各个门禁开关以及在界面显示相关信息；环境检测端检测温湿度烟雾状况，车辆通过状况以及停车位状况，经STM32处理后由树莓派无线传输至PC端；PC端为后台，为平台端和手机端提供数据库支持和信息转发，同时可在网页查看远程监控视频；手机端为用户端，可注册新用户，充值，控制门禁开关以及显示消费记录。
本系统经过测试，可实现在无人监管下的自助停车管理。用户可通过刷卡和手机两种方式计时收费停车，可推荐停车位，智能门禁控制，手机用户还可手机控制停车场内其他场所的门禁开关，两种方式皆可网上充值或营业厅充值。停车场管理者可远程监控停车场内实时情况以及环境状况，实现无人监管。
本系统还提供了一个多功能巡逻车，用于细节方面的监控与管理。

Abstract
Now with the development of computer networking technology, intelligent parking lot will also use RFID tag identification technology, authentication, parking; now there have been many RFID smart parking around us, through field trips and view online information display Its basic functions: identification card, open access, or pay-per-clocked. Cards are divided into membership card and temporary card. For the treatment of emergency situations, it must be manually regulated. Based on the status, I designed a RFID smart parking management system, increasing the mobile client payments, remote control and video monitoring.
The design is based on a comprehensive RFID platform, hardware-based Samsung's latest S5PV210 embedded microprocessor. S5PV210,Which integrates the ARM Cortex-A8 core and belonging to 32 RISC microprocessor, is widely used in the development of mobile phones and portable devices, cost-effective. Using the UHF-900M UHF reader module platform provides high-speed gates controller module, electronic lock controller module and access gates controller module,With STM32 microcontroller, DHT11 temperature and humidity sensor, smoke sensor module, infrared tracking module and ultrasonic module.Software design is divided into QT platform software design and JAVA based web design and mobile terminal APP design.
The system is divided into four parts: RFID platform terminal,Environmental detection terminal, PC terminal and mobile terminal, via socket communication between the four. Platform side through A8 gateway handles credit card or mobile client information, the control switch and each access interface displays information; Environment detection end detection of temperature and humidity smoke state, the vehicle through and parking status, the STM32 treated by raspberry pie wireless transmission to the PC;PC end is the background, providing database support for the platform side and mobile terminal and information transfer, and remote monitoring video can be viewed on the page; mobile terminal for the client, you can register new users, recharge, control access switches and a display of consumer records.
The system has been tested to achieve unsupervised self parking management. The user can swipe through two ways unmetered parking and mobile phones, Can recommend parking, intelligent access control,mobile phone users can control a car park access control switch other places, in two ways can online recharge or recharge the operating room.Parking management can remotely monitor the real-time situation of the parking lot and the environment, and realize no supervision.
The system also provides a multi-function car,monitoring and management for details.
