| 摘 要： | 提出了一种处理复合火灾传感器信号的模糊方法．首先提取传感器输出的烟雾和温度信号特征，包括幅度、持续时间和变化量等，然后通过适当的隶属函数模糊化，再由模糊语言规则推理得到有烟明火、无烟明火、阴燃火和非火灾的判决结果，最后利用质量中心法去模糊得到系统的火灾报警／非报警输出．实验表明，这种方法能够有效地探测试验火，并能克服干扰、减少误报警．

| Abstract: | A fuzzy method of multisensor signal processing for automatic fire detection is proposed. Fuzzy membership functions of the amplitude, the duration and the magnitude of variation of the temperature and smoke signal outputs extracted are formulated. The decision results concerning whether it is a fire with smoke, a fire without smoke, a smoulder or not a fire at all will be obtained using a set of fuzzy grammatical inference rules. The system then gives fire or no fire alarm output by defuzzification with the centroid method. Test results show that the system can effectively detect standard test fires in time and is also capable of overcoming any interference with a low rate of false alarm. |
