FIELD: physics, alarm and protection. ^ SUBSTANCE: method is proposed for making a fire alarm, based on merging data, involving the following steps: using at least one temperature sensor for measuring and outputting values of two non-equivalent electrical parametres, and specifically a first electrical parametre and a second electrical parametre in a defined moment in time; transmission of values of the two non-equivalent electrical parametres to a device for measuring electrical signals, calculation of the function value for the given moment in time in a device for processing merged data in accordance with a predefined function, which includes at least the first electrical parametre and the second electrical parametre, comparison of the obtained function value with a predefined value; assessment of the need for sending out a fire alarm signal, launching the fire alarm device if necessary, using the comparison result. In another engineering solution, two temperature sensors are used, through which measurement is done and two non-equivalent electrical parametres are obtained, specifically a first electrical parametre and a second electrical parametre, respectively. Also two types of non-equivalent electrical parametres can be measured successively in two different moments in time. ^ EFFECT: increased accuracy of the detector and reduced coefficient of false alarm. ^ 10 cl, 4 dwg |
