摘要
A system and a method of data fusion fire alarm, wherein at least one line type temperature sensing element is used to detect and produce values of at least two nonequivalent electric parameters, namely, a first electric parameter a and a second electric parameter b at a certain time; the values of the two nonequivalent electric parameters are transmitted to an electric signal measuring device, and are used to obtain a function value at the time by a data fusion device according to a predetermined function having at least the first electric parameter and the second electric parameter, then the obtained function value is compared with a predetermined value; whether to send out a fire alarm signal is judged according to the comparative result, and starting a fire alarm device if necessary. Another technical solution may use two line type temperature sensing element, which detect and produce two nonequivalent electric parameters, namely a first electric parameter and a second electric parameter respectively. Also, two types of nonequivalent electric parameters at two different times may be detected sequentially.
