DSP 器件具有著高速度、高精度的運算能力，而且體積小，使得其應用越來越廣泛。系統通過CCD 攝像頭，在前加紅外濾光片后，由DSP（文中采用TMS320C31）
采集到紅外圖像去干擾后進行雙波段處理，從而進行有無火災的檢測。采用的雙波段的
檢測手段，可以進行在攝像范圍之內的檢測，而不受距離的約束。檢測方法快捷，準確，增加了系統的實時性和準確性。

The Embedded System Of Fire Detection On Image-processing Wang Benxi, Guan Hongyun，Fang Jian’an,Du Haitao (Donghua University , College of Information Science,Shanghai,200051 ) Abstract：DSP (Digital Signal Processor) is widely used for its high speed and precise computation .The system uses DSP（TMS320C31） to collect infrared image by CCD (Charge Coupled Device) camera, there is an infrared filter in front of the camera.Then it can detect fire by processing the image using dual-band without limitation of distance. This system is very early and reliably in detecting fires.
