摘　　要：采用ARM9系列的S3C2440A芯片作为该系统信息采集终端的核心处理器,通过SHT10和MQ-2传感器采集温度、湿度、烟雾可燃气体参数,用红外摄像机进行烟雾视频图像采集,通过WCDMA网络将采集到的信息发送到上位机。由于采用S3C2440A作为信息采集终端的核心处理器引入了嵌入式系统实现了视频图像和信号的前端处理,提高了预警的准确性,利用该处理器能够在正常模式与休眠模式之间切换的特性,降低了终端的功耗,大大提高了其续航能力。It uses S3C2440 of ARM9 series as the core processor of the system＇ s information collection terminal, through the sensors of SHT10, MQ-2 to collect the parameters of temperature, humidity and smoke, and uses infrared camera collect the video image of smoke. The collected information is sent to control center through the WCDMA network. $3C2440A is used as the core of information collect terminal, so the embedded system is introduced and realized the video image and the signal are processed at the front-end. The warning accuracy is improved. The processor is able to switch between normal mode and sleep mode. The terminal power consumption is reduced, and the duration of the terminal＇ s power is greatly increased.
