摘要
设计了一种林区火灾监测及报警系统。林区自组织网络采用ZigBee技术和无线射频芯片CC2530设计。其数据采集节点上配置的温湿度传感器和红外火焰传感器可以实现对林区环境的实时监测,并辅以GPRS网络技术将数据远程传输至监测中心,利用数学建模及软件分析对突发情况下火场的范围、火势的大小及蔓延形势进行运算,并通过图形化的人机交互界面实现对林区的火灾监测。为延长野外环境下系统工作时间,对终端节点采用休眠技术,对路由节点和协调器节点采用太阳能供电技术。实验表明,该系统能稳定有效工作,达到准确直观地对火灾情况进行判断和报警的要求。
A self-organizing forest fire monitoring and alarm system is designed by using ZigBee technology and radio frequency chips CC2530. Data acquisition nodes are equipped with temperature, humidity sensors and infrared flame sensors to achieve real-time detection of forest environment, along with GPRS technology to upload data to monitoring center. By means of mathematical modeling and software analysis, range, size and spread situation of forest fire under emergency circumstances are calculated and predicted, and forest fire is monitored through a graphical interactive user interface. Solar cells are used to recharge coordinating node and router nodes, as well as hibernation mode of terminal nodes are adopted, for the sake of long working time. Experiments conclude that the whole system can work efficiently and stably, and is able to achieve the goal of predicting and alarming forest fire with accuracy.
