摘要：
A new fire warning system based on the technique of multiplexing of Identical Fiber Bragg Grating (IFBG) and its application in petrochemical tank and tower are presented in this paper. Sensors of IFBG can largely increase the multiplexing number of sensors and can reduce the cost of demodulation. The number of multiplexed FBG in the IFBG array has come to 100. The new fire warning system has been applied in some petrochemical tank and tower, such as Sinopec Zhenhai Refining and Chemical Company Limited, and has obtained a very good effect.
