森林火灾无线监测预警系统的设计与实现

Design and Implementation of the Monitoring and Early Warning System for Forest Fires

针对传统森林火灾监测措施实时性差、实际应用受限的问题,利用无线传感网络技术,构建了基于ZigBee和GPRS的森林火灾监测预警系统。介绍了系统的结构,给出了主要功能模块的硬件设计方法和ZigBee无线传感网络中各功能节点的软件设计。同时,对传统的无线传感网的自组网方案进行了改进,并在分布式组网方案基础上实现了ZigBee无线传感网络节点的分簇置放。实践证明,该系统实现了森林火灾监测和预警的功能,提高了系统中数据传输的实时性、可靠性以及系统的可扩展性。

Aiming at the problems existing in traditional monitoring measures for forest fires, e. g. , poor real-time performance and limited in practical applications; with the wireless sensor network, the forest fires monitoring and early warning system based on ZigBee and GPRS is constructed. The structure of the system is introduced, and the hardware design of the main functional module as well as the software design of each function node in ZigBee wireless sensor network is given. In addition, the Ad Hoe networks scheme is improved, and on the basis of distributed network scheme, the clustering placement of the ZigBee WSN nodes is implemented. The practice proves that the system implements the monitoring and warning function, and the real-time performance, reliability and expandability in data transmission are improved.
