基于北斗卫星的森林火灾监控终端设计

针对传统森林火灾监控方式存在的受地形限制,导致火灾发现不及时和定位难的缺陷,设计了基于北斗卫星的森林火灾监控系统,实现了火灾智能识别和预警,并且可以对火源、火场进行快速定位和信息通报;终端包括烟采集处理模块、图像采集模块、DSP处理模块、ARM主控模块和北斗卫星通信模块五部分,从烟和火焰两个方面对森林实时进行监控,分别采用离子烟雾传感器和DSP火焰识别混合算法,提取火焰图像差值和火焰图像边界参数的方法,提高了识别的准确率;试验证明,系统具有结构简单、使用方便和识别智能化的特点。

Terminal Design of Forest-fire Monitoring Based on Beidou Satellite

Traditional fire monitoring system of forest is limited by the terrain,which results in untimely succor and inaccurate location.Aiming at this defect,a new forest-fire monitoring system based on the Beidou Satellite is designed,which can intelligently identify the fire and make early-warning,coupled with the quick location and information delivery.Terminal acquisition and processing module including smoke,the image acquisition module,DSP processing module,ARM Compass satellite control module and communication module in five parts.This terminal conducts the real-time monitoring on the forest from smoke and flame;moreover,the algorithm which has combined ionic smog sensor and DSP flame detection is applied,The difference between flame images and extracts the boundary parameters of the flame image,to improve the accuracy of the Identification.Tests proved,this design owns the features of simple structure,convenient operation and intelligent identification.
