TMS320DM642 is a kind of high performance DSP component which is applied in multi-media specially and is used widely.Multi-parameter fire detection system based on TMS320DM642 can collect information about image,temperature,smoke-thickness.It can detect fire according to information about texture picked up from fire image,temperature,smoke-thickness.It can be applied to fire-monitor of important room.The information about image,temperature,smoke-thickness can be also encoded,stored,and transferred.It is verified in the experiment that this system can distinguish fire from nuisance caused by daylight lamp and alcohol burner.And it has a better anti-jamming performance.The distributed intelligent fire monitor system can be set up easily thought network building,and it has good foreground in applications.
