ABSTRACT In fire alarm and monitoring system, fire detector is provided with great function. But traditional fire detector does not possess or be short of the ability to detect in early state fire. Because that signal of fire alarm and monitoring isn't alarmed in time and fire is controlled effective, to cause heavy losses by fire. In this paper, it is start that to analyze mechanism of fire occurred process and combine case of fire, multi-sensor fire detector is design. And the proposed fire detector may detect and recognizes signal of early fire in the early state of fire by photo-electricity, temperature. Acquisitive signal is sent to amplify and shape. And then shaped signal is introduced TMS320VC5402 DSP chip. Intelligent recognition program is embedded in the TMS320VC5402 DSP. The program embedded judges alarm signal. And the position of fire happed and the fire signal are messaged to host computer by bus means. Fire signal and fire alarm are confirmed in real time by this proposed fire detector. And ability of its sensitivity and reliability is advanced and enhanced.
