【摘要】：随着人们生活水平的提高，，汽车数量急剧增加，这给人们出行带来方便的同时，也引发了停车难的问题。本文对停车场管理系统的应用现状进行研究，发现其存在一定的缺陷，因此提出智能停车场车辆RFID定位关键技术的研究课题。未来智能化的停车场系统对车辆的信息采集是全方位的，尤其是停车场内的车辆位置信息，为停车诱导服务系统提供支撑。智能停车场利用RFID技术增强数据信息采集的兼容性，通过构建轻量级的RFID中间件系统，为停车场应用层软件开发提供方便的接口平台。本文研究的内容主要包括适用于停车场应用场景的RFID室内定位算法、RFID实时定位中间件系统。分析了RFID室内定位基本理论，在经典的LANDMARC定位算法基础上提出了一种双层定位模型的D-LANDMARC算法，相比LANDMARC算法，D-LANDMRAC算法定位精度有了明显的提高。详细分析了中间件的结构及各个核心模块，通过简化应用层接口，综合考虑实用性、易操作性等特点，设计了基于事件处理模式的轻量级RFID实时定位中间件架构。最后对智能停车场硬件设备的选型以及设备网络架构进行阐述，利用模拟的阅读器软件对中间件系统以及定位算法进行测试，并通过运行图形化的停车场管理平台软件来展示预期的应用效果。
[Abstract]:With the improvement of people's living standard, the number of cars increases sharply, which brings convenience to people to travel, but also causes the problem of parking difficulty. This paper studies the application status of parking lot management system, and finds that there are some defects in it. Therefore, the key technology of intelligent parking vehicle RFID positioning is put forward. The future intelligent parking system is omnidirectional to the vehicle information collection, especially the vehicle position information in the parking lot. Intelligent parking lots make use of RFID technology to enhance the compatibility of data collection and provide a convenient interface platform for parking application layer software development by constructing lightweight RFID middleware system. The content of this paper mainly includes the RFID indoor positioning algorithm and the RFID real-time positioning middleware system, which is suitable for the parking lot application scene, and analyzes the basic theory of RFID indoor positioning. Based on the classical LANDMARC localization algorithm, a double-layer localization model D-LANDMARC algorithm is proposed, which improves the positioning accuracy of D-LANDMRAC algorithm compared with LANDMARC algorithm. The structure of middleware and each core module are analyzed in detail, and the interface of application layer is simplified. Considering the characteristics of practicability and maneuverability, a lightweight RFID real-time positioning middleware architecture based on event handling mode is designed. Finally, the selection of hardware equipment and the network structure of the equipment are described. The middleware system and location algorithm are tested by using the simulated reader software, and the expected application effect is demonstrated by running the graphical parking lot management platform software.
