Flame sensor is an indispensible part of the fire prevention system, its reliability and quality directly influence the safety of the work site. In order to monitor flames effectively,and meanwhile reduce the false alarm rate,the theory of UV (ultraviolet ray)flame detective sensors and IR (infrared) flame detective sensors was studied and an new flame sensor based on the multiply detective principle of UV and infra rays were put forward,including its design scheme and working process. Compared with the original flame sensor based on the single detective principle,the new flame sensor based on the UV and IR composite detective principle is more accurate,reliable and stable. Besides the new flame sensor possess the characteristics of high-sensitivity,quick-response and interference-free etc..
