摘要
提出了一种基于无线传感器网络的在途危险物实时动态监控系统。该系统可根据不同运输工具及危险物种类选择安装相应传感器节点并无线自主组网,通过通用分组无线业务(GPRS)实现远程无线数据访问与传输,使得控制中心能够对运输过程中危险物的状态进行全程跟踪、实时动态监控。给出了系统结构和软硬件的设计方案。实验结果表明:设计的系统测量误差较小,能够满足实际使用要求。
An in-transit real-time monitoring system for dangerous goods status, as well as its location based on wireless sensor networks （WSNs） is presented. The sensor nodes can be selected according to different kinds transportation tools and dangerous goods. Each of the sensor not may either be deployed the means of transport or attached to the dangerous gOods. After being loading into the system all deployed sensors notes autonomously form Ad hoc sensor networks. So the remote wireless data can be access and transmitted through the sensor network in- vehicle by GPRS. The design scheme of system structure, hardware and software. The experimental results show that the measurement error of designed system is very small and can meet practical needs of use.
