基于ARM的嵌入式森林防火预警系统的设计 森林火灾突发性强、破坏性大、救助困难，其防治工作。为此，本文介绍一种基于嵌入式的森林防火预警系统。此系统要满足工作的需求，研究发现，ARM-Linux体系具有低功耗、开源稳定等特性，该系统采用ARM9的芯片作为控制器，利用摄像头将现场传送到监控，通过传感器森林的数据，传给主控制器，同时通过网络协议传送至监控。进行数据融合分析，决定是否报警。本系统不仅能自动监控，又能监控处，。ARM-Linux体系结构化的开发模式稳定易维护，分析与测试表明，此系统分析精确可靠性，能够及时报警，这种灵活的森林防火预警系统实现全天远程监控有望得到广泛的应用。关键词：森林防火预警；低功耗；ARM-Linux；数据融合；远程监控Abstract：Forest fire has strong sudden, destructive and difficult rescue, and its prevention and cure is of great significance to the national construction. To this end, this paper describes an embedded forest fire warning system. This system should meet the need of long-term work. Research findings, Linux-ARM embedded system has the characteristics of low power consumption, open source and stability, etc. The system is based on ARM9 chip as controller. Use the camera to send the field image to the monitoring department. And through sensors, acquire forest related data, pass the data to the master controller, and at the same time to the monitoring side through the network protocol. The system makes data fusion analysis, decide whether to alarm. This system can not only monitor automatically, but also can return the information to the monitoring department so increase the intensity of monitoring. ARM-Linux system structure development mode is stable and easy to maintain. Analysis and test show that the data analysis of this system is accurate and the reliability is high, and can be timely warning. This flexible forest fire warning system can realize the whole day remote monitoring and controlling. And its possible to get a wide range of applications.
