为了有效地探测舰船火灾,根据舰船火灾信号的特点,选取CO浓度作为火灾探测信号的特征,并提出采用灰色系统模型预测CO浓度增大趋势,通过与实际探测值比较得出相应时刻的预测误差,进而判断是否存在火灾威胁的探测方法,同时结合舰船工作环境的特点,设计了三级火灾报警等级。仿真结果证实了该方法的有效性,对现有的火灾探测方法是一种补充。
In order to detect ship fire effectively, the CO concentration is selected as the characteristic of fire detection signal according to the characteristics of warship fire signal. The gray system model is proposed to predict the increasing trend of CO concentration. By comparing with the actual detection value, Forecast error, and then determine whether there is a fire threat detection method, combined with the characteristics of the ship’s working environment, designed a three-level fire alarm level. The simulation results confirm the effectiveness of this method and complement the existing fire detection methods.
