摘 要: 设计了森林火灾的自动报警及定位系统,硬件采用ARM9内核嵌入式处理器S3C2440,使用热成像摄影机检测火灾信号,由DSP处理后向处理器发出报警信号,软件采用uC/OS-II操作系统进行系统软件多任务管理。设计了4个任务实现系统功能,给出了每个任务的实现方法。制作样机并进行实验,实现了系统要求的各项功能。 A forest fire positioning and automatic alarm system is designed. The ARM9 core embedded processor S3C2440 is utilized and the thermal imagine camera is used to detect fire signal. After dealing with the signal by DSP, the alarm signal is sent to the processor. The uC/OS-II operation system is used to manage the multi-task software. Four tasks are used in order to realize the function of the system. Every task's realization is give. Test machine is made, which can realize all functions required by the system.
