基于WSNs的危险品车辆在途监测预警系统

摘要

This paper put forward a monitoring technology based on WSNs, designing and implementing an in-transit real-time vehicle - mounted system for on- road monitoring of dangerous goods. It uses various kinds of professional sensors to detect the physical condition of dangerous goods, the sensor nodes collect and submit the data after Ad hoc networks) also uses gyroscope to detect the vehicle attitude, and import the technology of GPS and GIS to achieve tracking and trajectory mapping of the vehicle; last it achieve the data access and transmission between the vehicle-mounted system and monitoring center through wireless communication. The vehicle-mounted system provides users with access authentication, navigation, remote inquire and autoalarm. Etc. Test in practice shows the system works well.%提出了一种基于无线传感器网络的监测技术,设计并实现了一套用于危险品在途监测的实时动态车载系统；该系统利用各类专业传感器检测危险品的物理状态信息,各传感器节点自主组网实现数据的采集上报；还利用陀螺仪检测车辆的运行姿态,并引入全球定位系统和地理信息系统的相关技术实现车辆的全程跟踪和轨迹绘制；最后通过无线通信实现车载系统与监控中心的数据访问与传输;车载系统向用户提供接入认证、导航、远程查询及自动报警等功能.道路测试证明系统工作可靠.
