针对目前大空间火灾探测的难点，研究出了一种基于双波段视频检测的智能水炮系统。将DSP芯片TMS320DM648 作为视频处理芯片并采用STM32f103 作为控制芯片，利用双波段（红外与可见光）对火灾的热、色、形以及光谱与运动特性进行识别，使火灾探测准确度大大提高，采用步进电机作为整个系统的驱动部分，CAN 作为通信总线提高了水炮的反应速度与灵活性。智能水炮在25 s 内可定位火源进行灭火，监控距离可达100 m，误报漏报率极低，为大空间消防提供了更好的选择。

Aiming at fire detection in large spaces, a new intelligent water cannon system based on dual-band video detection is studied, which takes DSP chip TMS320dm648 as the video processing chip and STM32f103 as control chip. Dual-band(infrared and visible light) was used to study heat, color, shape, spectrum and motion characteristics of fire to estimate the fire. The accuracy of fire detection was improved. Stepper motor is used to drive the intelligent water cannon and CAN is used as the communication of the whole system to improve the reaction speed and flexibility of intelligent water cannon. The system can locate fire source in 25 s and then carry out fire-fighting. And it can monitor the space within 100 m. This system will be a better choice for large spaces fire fighting.
