【摘要】：无线传感网,直观的说,就是以现代科技的方法对没有生命的各类生活中的设备进行改造,并进行信息的传递和交互。自从被提出以来,无线传感网迅速引起全世界各个国家和地区的重视,借助于相关支撑技术的发展、国家机器的推动和难以量化的市场需求,得到井喷式发展,并迅速染指于物流管理、智能交通、环境管理、医疗卫生和国防安全等各个领域,取得了许多重要的成就,并带来了深刻的变革。本文研究基于无线传感网定位技术的车流量监测系统,在实验室现有的城市管理项目平台和研究成果基础上进行推进性研究和拓展,通过无线传感网定位技术对区域内的车辆进行动态定位来捕捉车辆在具体时刻的位置信息,并结合智能交通领域的知识,以此为依托设计和开发了车流量监测系统,实现了对特定区域的设备管理、车辆信息管理和该区域内的车流量状态监控。基于无线传感网定位技术是该系统的一大特色,也是系统可靠性和准确性的前提。因此,本文首先对无线传感网定位技术进行了介绍,通过对不同的定位技术的优缺点进行对比,并结合实验室无线传感网平台的现状和系统实际需求,通过借鉴RSS算法的思想对质心定位算法进行优化,使优化过的算法在精度和效率可以为本课题所用；接下来,从需求分析开始,结合无线传感网平台和系统的软硬件实际情况,得出了车流量监测系统应该具备的功能需求和非功能需求,划分了系统的各个模块；然后,对系统进行详细设计,以逻辑架构、物理架构、数据架构和开发架构这四个视图为四个不同的视角对系统的各个模块进行了详细设计,最后采用了百度地图API和SSH结合的方式对系统进行了编码实现,并进行了完整的测试,取得了令人满意的成果。
[Abstract]:Wireless sensor network (WSN), intuitively, is to transform all kinds of inanimate equipments in life by modern science and technology, and to transmit and interact information.Since it was put forward, the wireless sensor network has attracted the attention of all countries and regions in the world. With the help of the development of relevant supporting technology, the promotion of the state machine and the difficult to quantify the market demand, the wireless sensor network has got the blowout development.And quickly involved in logistics management, intelligent transportation, environmental management, health care and national defense security and other fields, has made many important achievements, and brought profound changes.In this paper, the vehicle flow monitoring system based on the wireless sensor network positioning technology is studied and expanded on the basis of the existing urban management project platform and research results in the laboratory.A vehicle flow monitoring system is designed and developed based on wireless sensor network (WSN) positioning technology to capture the position information of the vehicle at specific time and combine with the knowledge of intelligent transportation, based on which the vehicle flow monitoring system is designed and developed.The equipment management, vehicle information management and traffic flow state monitoring in the specific area are realized.Location technology based on wireless sensor network is a major feature of the system, and is also the premise of system reliability and accuracy.Therefore, this paper first introduces the wireless sensor network positioning technology, through the comparison of the advantages and disadvantages of different positioning technologies, and combined with the laboratory wireless sensor network platform and the actual needs of the system.By using the idea of RSS algorithm for reference to optimize the centroid location algorithm, the optimized algorithm can be used in accuracy and efficiency. Then, starting from the requirement analysis, combining with the actual situation of software and hardware of wireless sensor network platform and system,The functional and non-functional requirements of the vehicle flow monitoring system are obtained, and each module of the system is divided. Then, the system is designed in detail, with the logical structure and the physical structure.The four views of data architecture and development architecture are designed in detail for each module of the system from four different perspectives. Finally, the system is coded and implemented by combining Baidu Map API and SSH, and the complete test is carried out.Satisfactory results have been achieved.
