摘要:不停车门禁系统是物联网典型应用之一。不停车门禁系统可以实现进出车辆的动态监测与控制，能够有效提高单位或小区车辆进出效率，提高车辆进出的管理水平，越来越被各个部门以及企事业单位所重视。目前最为常见的车辆管理方式是使用非接触式IC卡，但是由于非接触式IC卡的读写距离较近，车辆进出大门时必须停车刷卡。在车辆进出频繁的时间或位置，必然会出现车辆的堵塞情况。本文针对这种实际情况，采用有源RFID标签技术解决这一难题，并根据车辆进出管理的实际情况，设计了一种基于2.4GRFID有源标签识别技术的车辆门禁管理系统。

　　　本文从实际情况出发，对小区车辆门禁系统功能和性能的需求进行分析，确定了本系统要实现的最终目标。并根据车辆进出管理的基本工作流程，以及工作过程中涉及到的数据、事件和对象，确定了本系统的功能模块，完成了本系统的总体设计。

　　　本系统采用RFID标签存储、传输和识别车辆信息，通过对RFID标签实现远程读取，将读取信息与数据库车辆信息匹配，确定车辆类别，智能开启或关闭大门档杆，实现无间断，无停留车辆进出。本系统相比传统IC卡门禁系统具有更高的车辆进出效率，是一种高效的车辆进出监控控制系统。

　　　本文通过在Microsoft Visual Studio 2010环境下，使用Visual C#结合SQL Server 2008数据库完成了系统的开发和数据库的设计。系统通过实际调试与运行，基本达到了预期目标并实现了相关功能，满足本设计要求，是一种符合数据传输可靠、数据记录合理，功能完善实用的车辆进出管理系统。本系统在对小区、机关单位等场所的智能化管理和车辆进出控制方面具有较大的实用价值，具有良好的推广应用前景。

Abstract:No parking access control system is one of typical applications in the aspect of internet of things. This system can achieve the dynamic monitoring and control, can improve the efficiency of the vehicle access in the unit or community, improve the level of management, more and more departments and enterprises pay attention on this system. Currently the most common approach of vehicle control is to use non-contact IC card, but the cars must park to credit card due to the short reading distance of non-contact IC card. The traffic jam must appear when the vehicle access is frequent. The RFID technology can resolve it according to the reality of vehicle management. It designs a vehicle management system according to the 2.4 RFID identification technologies. 

This article analysis the system function and performance needs of vehicle access system to ensure the final goal. According to the basic work process of vehicle management, the data, the events and objects to ensure functional modules of the system and complete the overall design of the system. 

This system uses RFID tags storage, transmission and vehicle identification information through remote reading of RFID tags and it will match the reading information and vehicle information, ensure the types of vehicles, smart open or close the door lever to achieve the uninterruptible and no stay vehicle access. This system has more efficiency vehicle access than the conventional IC card access control system and it is a high efficient vehicle access control system monitoring/

This article use Visual C# and SQL Server 2008 database to complete the system development and database design in Microsoft Visual Studio 2010 environment. System basically achieves the desired goals, related functions and meets the design requirements through the actual commissioning and operation. It is a reliable data transmission in line, reasonable data logging, and comprehensive and practical vehicle access management system. The system in the district, institutions and other places has great practical value in intelligent management and vehicle access control and it has good application prospects.
