摘要
针对目前全球森林及荒地火灾的严峻形势,提出了一种基于ZigBee无线传感器网络的森林火灾实时监测预警系统的框架及其实现方案。设计了基于JN5139芯片的传感器节点结构和硬件电路、无线网关节点,论述了网络数据传输的流程。该系统能够监测林区的空气温度、湿度及有林火产生时的烟雾稠密浓度等相关环境参数,能为相关部门采取防火、灭火或预警措施提供重要决策依据。
A wireless sensor network paradigm based on the technique of ZigBee for forest fire detection in real-time and early warning was put forward as well as its implementation scheme. The hardware architecture, circuit of sensor node were and wireless gateway node based on the chip of JN5139 were designed. The process of network data transmission was described in detail. The system can monitor the relevant environmental parameters, such as the forest temperature, humidity, and the dense of smoke produced by forest fires. Those data provide an important basis for decision making for the relevant departments to take fire prevention, fire fighting, or early warning measures.
