【摘要】 森林火灾是世界性的林业重要灾害之一,因此一旦有火警发生,就必须以极快的速度采取扑救措施。本文介绍了基于ARM的嵌入式森林防火远程无线监控系统的设计,采用ARM处理器和市场上广泛使用的价廉物美的ZC301芯片的USB摄像头,通过GPRS模块,将图像不断的发给远端的管理指挥中心。在火灾发生后的第一时间,自动报警模块将发出告警,真正做到早发现,早解决。硬件方面采用USB摄像头与S3C2410处理器组成嵌入式视频采集装置,并通过GPRS连接宿主机从而组成视频监控系统。软件方面分为系统软件的移植和应用软件开发两方面。系统软件方面包含ARM平台的BootLoader和嵌入式Linux的移植;应用软件方面包含前端ARM平台嵌入式视频采集软件设计,GPRS模块程序设计,监控中心程序设计三个部分。其中监测终端需要执行多个任务,主要采用Linux下多线程编程技术完成;监控中心基于J2EE技术的B/S结构,采用MVC设计模式,监控中心是一个提供用户登录、监视、操作、管理、的应用平台。通过它实现对现场环境的监控管理。更多还原

【Abstract】 Forest fire is one of the most dangerous world wide disasters. Once it happens, we must take measures as soon as possible. This paper introduces the design of the embedded forest fireproofing system based on ARM. The system can be wirelessly monitored by video from far away. It uses the USB web-camera with the chip of ZC301, which is low in price and high in quality. Through the module of GPRS, pictures will be sent back to the remote monitoring center. The automatic alarm module will raise the alarm as soon as the fire happens, and it helps the governor to find and resolve the fire at the first time.With regard to the hardware design, the embedded video capture system which consists of USB camera and S3C2410 as its CPU, together with the PC which is connected by GPRS, compose the video monitoring system.As far as the software design, the system software and the internet applications must be designed. First we must put the BootLoader and embedded Linux kernel to the target of ARM platform. Then a system of video capturing and a GPRS module need to be designed to run on the platform of ARM. In the end we should design a remote monitoring center.The terminal monitor is designed to execute multiple tasks which are completed mainly by Linux multi-threads programming; Monitor center is B/S structure based on J2EE and it uses MVC design pattern. Remote monitoring center is an applied platform for users to log in, monitor, operate, and manage. With remote monitoring center, on-site environment can be monitored and managed.更多还原
