【摘要】：随着经济的发展和人们生活水平的提高，居民拥有汽车的数量与日俱增，随之带来了小区车辆管理问题。非接触式IC卡是小区车辆管理系统目前最常用的管理方式，但是IC卡读卡距离较近，车辆必须停车刷卡方可进出小区。随着小区住户车辆的猛增，在车辆进出高峰期势必会造成交通的堵塞。此外，IC卡中的用户信息很容易被窃取造成车辆的丢失，给用户带来巨大的经济损失。本文针对这一现实情况，设计了一套自动化程度高和方便快捷安全的超高频RFID小区车辆管理系统。本论文的主要研究内容如下：一、系统的总体结构设计。对超高频RFID小区车辆管理系统进行需求分析，确定了系统的组织结构。小区车辆管理系统由硬件部分和软件部分组成：硬件系统包括入口设备、数据处理设备、安全监控设备、出口设备、收费设备、照明通风设备等；软件系统主要是上位机软件管理。二、系统硬件的设计。车辆检测设备：选用双通道环形线圈车辆检测器PD232，具有检测时间短、灵敏度和抗干扰性高、稳定性好等特点，满足小区各类型车辆的不停车出入要求。读写器的射频接口电路：射频接口电路包括本振频率信号产生器、混频器、带通滤波器、功率放大器等功能模块。本振频率信号发生器选择为NCPD6-915BR的锁相环频率合成器模块，混频器采用MRFIC2002进行变频处理，经过集成带通滤波器F5CE-915M00-236提取有用信号，最后信号经过功率放大器MAX2430输出。读写器天线：选取型号为TDJ-915BQ12-C的定向天线，其工作频率为902-928MHz，安装方式采用旁立安装，保证读写器天线与车载电子标签天线的极化方向相匹配。三、系统上位机软件的设计。选择SQL Server2008数据库来存储数据，利用Visual C#设计软件模块，包括登录模块、计费模块、车辆出入管理模块、车辆基本信息管理模块、用户卡管理模块和报表模块等，，分别给出了各个模块的功能、设计界面以及相对应的代码。本文通过设计超高频RFID小区车辆管理系统，有效地解决了用户车辆的安全、车辆进入小区的速度和停车计费等问题，实现了小区车辆管理的自动化和智能化。
[Abstract]:With the development of economy and the improvement of people's living standard, the number of cars owned by residents is increasing day by day, which brings about the problem of vehicle management in residential area. Non-contact IC card is the most commonly used management method of vehicle management system in residential area at present. But the IC card reading distance is close, the vehicle must stop and swipe the card to enter and exit the community. In addition, the information of users in IC card is easy to be stolen, resulting in the loss of vehicles, and brings huge economic losses to users. A vehicle management system of UHF RFID community with high automation and convenience and safety is designed. The main contents of this thesis are as follows:. First, the overall structure of the system design. This paper analyzes the requirement of the vehicle management system of UHF RFID community, and determines the organization structure of the system. The system is composed of hardware and software: the hardware system includes entrance equipment, data processing equipment, and so on. Safety monitoring equipment, export equipment, charge equipment, lighting and ventilation equipment; software system is mainly upper computer software management. Second, the design of system hardware. Vehicle detection equipment: double channel ring coil vehicle detector PD232, with the characteristics of short detection time, high sensitivity and anti-interference, good stability, to meet the requirements of all types of vehicles in the residential area. RF interface circuit of reader: RF interface circuit includes local oscillator frequency signal generator, mixer, bandpass filter, power amplifier, etc. The local oscillator frequency signal generator is selected as the phase locked loop frequency synthesizer module of NCPD6-915BR. The mixer uses MRFIC2002 to process the frequency conversion. The useful signal is extracted by the integrated bandpass filter F5CE-915M00-236. Finally, the signal is output by the power amplifier MAX2430. Reader antenna: select the directional antenna of TDJ-915BQ12-C, its working frequency is 902-928 MHz, the installation adopts side stand installation to ensure the polarization direction of the reader antenna and the on-board electronic tag antenna is matched. Third, the software design of the upper computer of the system. SQL Server2008 database is selected to store data, and Visual C # is used to design software modules, including login module, accounting module, vehicle access control module, vehicle basic information management module, user card management module and report module, etc. The function, design interface and corresponding code of each module are given respectively. By designing the vehicle management system of UHF RFID residential area, this paper effectively solves the problems such as the safety of the user's vehicle, the speed of the vehicle entering the residential area and the parking billing, and realizes the automation and intelligence of the vehicle management in the residential area.
