摘　　要：为解决传统电气火灾监测系统报警不及时的问题。设计了一种基于电子鼻技术的电气火灾早期预警系统。系统硬件由多个气敏传感器组成的传感器阵列和STM32L071单片机为核心的智能控制单元两部分组成,实现对电气火灾早期环境的监测及数据的传输。采用模糊理论与层次分析法相结合的方法实现多传感器信息的融合,降低监测误报率。实验结果表明所设计的预警系统可以准确反应环境特征并实现对电气火灾的早期预警。In order to solve the traditional electrical fire monitoring system alarm is not timely.An early warning system of electric fire based on electronic nose technology is designed.The system hardware is composed of sensor array composed of several gas sensors and intelligent control unit with STM32L071 single chip microcomputer as the core,which can monitor the early environment of electrical fire and transmit data.The method of fuzzy theory and AHP is used to realize multi-sensor information fusion and reduce the rate of false positives.The experimental results show that the designed early warning system can accurately reflect the environmental characteristics and realize the early warning of electrical fire.
