Аннотация: The paper focuses on the description of the characteristics of the upgrade heat flux sensor, as well as the consideration of various models of its application to identify the source of combustion. The device uses a photovoltaic cell used to determine the thermal radiation intensity. The value thus defined is subsequently digitized and applied to determine the location of the radiation source. Among other things, this enables to use the device for finding the fire coordinates in order to extinguish it effectively using robotized fire complex. It is proposed to upgrade the device, which is to extend the temperature range of operation, and also to increase the speed and number of detectors in the line. The paper also provides a structural diagram of the functional sensor elements. A patent has been received for an improved device. Since the photovoltaic cell of a new sample with improved properties is used in the device, the article also provides an analysis of its characteristics, influence curves of the intensity of the heat radiation source on distance, as well as lines of constant signal strength. The data obtained were used to create three types of fire detection models, depending on the geometric parameters of the protected premises and the location of the combustible content source. © 2020 Published under licence by IOP Publishing Ltd.
