【摘要】：无线传感器网络(Wireless Sensor Networks,WSN)是一种新兴的分布式传感网络,由末梢传感器感知外部对象信息,通过多跳自组织网络发送至后端。WSN以其自组织、全向性、小开销、节点简单的特点,在智能交通、安全监控、环境监控等领域应用拥有巨大的潜力。ZigBee技术是一种基于IEEE802.15.4标准的低功耗局域网协议,可以为WSN系统的实际应用提供了一种优秀的解决方案。ZigBee技术在短距离通信中应用广泛,具有近距离、低功耗、低复杂度、自组织、动态路由等特点。本课题旨在运用ZigBee技术实现WSN系统,实现客运车场内车辆的实时定位和管理功能。WSN系统分为传感网络部分和数据处理部分。传感网络部分拥有多个节点,部署在停车场内部和客运车辆中,节点间通过ZigBee网络实现通信,完成业务数据传输、客运车辆定位信息采集功能。数据处理部分仅一个节点,部署于停车场内部,是所有传感节点的根节点,汇总传感网络中所有信息,并实现传感器网络与互联网的网关功能,拥有一定的数据处理能力,可实现业务数据汇总、车辆实时定位,以及将车辆信息通过3G网络传输至后台服务器等功能。此WSN系统的特点为:基于ZigBee的WSN系统实现,以及车辆在室内环境中的实时定位算法实现。基于ZigBee的WSN系统不仅可以进行数据采集和节点间通信,还可以实现WSN网络参数设置和节点组网管理,是本课题中客运车辆管理系统的基础通信网络;车辆实时定位算法基于位置标记原理和指纹算法提出,是实现客运车场中车辆管理功能的基础。在实际停车场中部署了 WSN系统并进行测试:在业务功能方面,车辆和司机信息可实时发送至后台,车辆定位正确率为79.2%,并可以准确判断车辆进出站;在系统管理功能方面,后台可实时查询和管理WSN系统各项参数,并可以对系统各节点设备进行升级。由测试结果可知,本WSN基本实现了课题中客运场站管理的需求。
[Abstract]:Wireless Sensor Networks (WSN) is a new kind of distributed sensor network. It is sent from the end sensor to the back-end. WSN through multi-hop self-organization network with its characteristics of self-organization, omnidirectional, small overhead and simple node. ZigBee technology is a low power LAN protocol based on IEEE 802.15.4 standard. ZigBee technology can be used widely in short distance communication. It has the characteristics of short distance communication, low power consumption, low complexity, self organization, dynamic routing and so on. The purpose of this paper is to use ZigBee technology to realize the WSN system and realize the real-time location and management function of the vehicle in the passenger depot. WSN system is divided into the sensor network part and the data processing part. The sensor network has several nodes, which are deployed in the parking lot and passenger vehicles. The nodes communicate with each other through ZigBee network to complete the business data transmission and the location information collection function of passenger vehicles. The data processing part is only one node, which is deployed inside the parking lot. It is the root node of all the sensor nodes. It aggregates all the information in the sensor network, and realizes the gateway function between the sensor network and the Internet. It can collect the service data, locate the vehicle in real time, and transmit the vehicle information to the background server through 3G network. The characteristics of this WSN system are the realization of ZigBee based WSN system and the realization of real-time location algorithm of vehicle in indoor environment. The WSN system based on ZigBee can not only collect data and communicate among nodes, but also realize the setting of WSN network parameters and network management of nodes. It is the basic communication network of passenger vehicle management system in this subject. Vehicle real-time location algorithm is based on the principle of location marking and fingerprint algorithm, which is the basis of vehicle management in passenger depot. The WSN system is deployed and tested in the actual parking lot. In terms of business functions, the vehicle and driver information can be sent to the background in real time, the vehicle positioning accuracy rate is 79.2%, and the vehicle entry and exit station can be accurately judged. Background can query and manage the parameters of WSN system in real time, and upgrade every node device of the system. According to the test results, this WSN basically realizes the demand of passenger station management in the subject.
