摘　　要：针对单一普通型火灾探测器的环境适应性和功能局限性,将多传感器信息融合技术应用于火灾报警系统,实施多个传感器同步探测,全面提取火灾信息。同时,应用智能算法,对提取到的信息进行融合,实现信息的优化,完整地反映环境的信息,准确地预报火灾。在此采用多传感器信息融合方法中的Bayes理论,给每类火灾探测器的探测结果分配相应的概率,然后运用Bayes理论,进行信息的融合,从而获得最终的判决结果。有效地降低了误报率和漏报率,提高了整个火灾报警系统的可靠性。Because of environmental adaptability and functional limitations of the single common type fire detector, multi- sensor information fusion technology is applied to the fire alarm system to implement the multi-sensor synchronous detection and fully extract the fire information. The intelligent algorithm is adopted to fuse and optimize the extracted information, so as to completely reflect environment information and accurately forecast the fire. Bayesian theory in the muhi-sensor information fusion method is used to assign the corresponding probability to the detected results from each type of the fire detector, and then using Bayesian theory to fuse the information to obtainthe final results, which can effectively reduce the false alarm rate and missing alarm rate, and improve the reliability of the entire fire alarm system.
