摘要:

针对传统林火监测技术的不足,将先进的无线传感器网络技术与嵌入式技术相结合并应用在森林防火监测中,从而提出了一种可增强林火识别率的智能森林防火监测系统。该系统采用无线网络协议ZigBee来进行组网,具有组网简单、路径信息占用存储器容量小等优点,非常适合林区的监测环境,且可有效地降低系统的能耗和成本。实验表明:该系统具有运行稳定及组网灵活等特点,可对森林监测区域的环境信息进行实时监测。当发现火情时系统采用DV-Hop算法可自动实现准确定位并及时发送警报信息,从而为后续的林火扑救工作打下良好的基础,同时也为林业智能数字化建设工作提供了参考和借鉴。

Abstract:

Aiming at the deficiencies of traditional forest fire monitoring techniques, the advanced wireless sensor network technology and embedded technology are combined and applied to the forest fire monitoring system. Thus, this kind of enhanced intelligent forest fire monitoring system that can increase the forest fire recognition rate is put forward in this paper. The system uses the wireless network protocol,ie ZigBee network. The ZigBee network is simple, has small path information occupy memory capacity, is suitable for monitoring the environment of forest, and can effectively reduce the energy consumption and the cost of system. Experimental results showed the system has the characteristics of stable operation and flexible network, which can be used for the real-time monitoring of the environmental information of the forest monitoring region. When fire is found, the system will use the DV-Hop algorithm to automatically realize accurate positioning and timely send the alarm information. This is a good foundation for subsequent fire fighting work and provides a reference for intelligent digitization of forestry construction work as well.
