基于ARM的嵌入式森林防火预警系统的设计 摘 要 森林火灾作为一种突发性强、破坏性大、处置救助较为困难的自然灾害之一，其防治工作已经成为中国防震减灾和国家公共应急体系建设的重要组成部分，因此设计并完成一种有效的森林防火预警系统对国家建设有着重要的意义。为此，本文介绍一种基于嵌入式的森林防火预警系统。 此系统要满足长期、无间歇监控工作的需求，研究发现，ARM-Linux嵌入式体系具有低功耗、开源稳定等特性，该系统采用ARM9 系列的S3C2440A芯片作为核心控制器，通过对Linux内核中Video4linux2驱动的使用，利用摄像头将现场信息传送到监控中心，并通过各类传感器将森林的温湿度、烟雾等数据采集出来，经AD转换及IO数据的读取，将得到的数据传给主控制器，同时通过网络协议传送至监控方。主控制器进行数据融合分析，决定是否鸣叫警示和发送报警信息。本系统不仅能自动监控、报警，又能通过网络将信息传送至监控处，使得监控人员更加了解森林情况，从而更加有效及时地对森林火灾进行预警报告。 ARM-Linux嵌入式体系结构化的开发模式具有稳定、可靠、易维护等特点，分析与测试表明，此系统采集数据具有较高的可靠性，数据分析精确，能够及时报警，这种灵活的森林防火预警系统在实现全天候远程监控的同时更提高了预警质量，有望在今后得到广泛的应用。 关键词：森林防火预警；低功耗；ARM-Linux；数据融合；远程监控Design of embedded forest fire prevention and warning system based on ARM Abstract Forest fire is one of the natural disasters, which is one of the more sudden, destructive and difficult to dispose and rescue. Its prevention and cure has already become the important part of the China earthquake disaster reduction and the national public emergency system construction, so it is important to design and accomplish an effective forest fire warning system for the national construction. To this end, this paper describes an embedded forest fire warning system. This system should meet the needs of the long-term and uninterrupted monitoring. Research findings, Linux-ARM embedded system has the characteristics of low power consumption, stability and open source. The system uses the ARM9 S3C2440A chip processor as the core controller. Through the use of Video4linux2 driver in the Linux kernel, use the camera to send field information to the monitoring center, And through all kinds of sensors, collect the forest temperature and humidity, smoke and other data, via conversion of AD and IO data read, pass the data to the master controller, and at the same time to the monitoring side through the network protocol. Master controller makes data fusion analysis, decide whether to tweet alerts and send alarm messages. This system can not only monitor the al
