Robotic fire-extinguishing systems. Effective extinguishing parameters

Introduction. The emergence of robotic fire monitors (RFM), which form the basis of robotic fire suppression systems (RFSS), has significantly expanded the functionality of fire monitors used in extinguishing fires, and, accordingly, affected the extinguishing parameters. The purpose of the article is to substantiate the parameters of effective fire suppression by RFSS.

Effective extinguishing parameters. Firefighting monitors are used for extinguishing most of the fires. The development of robotic fire monitors (RFM) has significantly expanded the functionality of technology, which has become the basis of robotic fire suppression systems (RFSS).

The main advantage of the RFSS is the ability to detect the source of ignition at an early stage and extinguish it with the entire flow of the fire extinguishing agent (FEA) by targeted supply of a jet of FEA to the source of ignition along a ballistic trajectory. This creates a high intensity of irrigation, which allows a quick elimination of the source of fire, which significantly increases the efficiency of fire extinguishing and reduces damage from fire. Standards for traditional automatic fire suppression systems (AFSS) include standard extinguishing parameters for irrigation intensity in, total flow rate Qn and extinguishing time tn. Extinguishing on the area St is carried out at a constant normative intensity of irrigation in, while the flow rate of extinguishing Qt will be a variable value depending on the extinguishing area. A feature of RFSS, in contrast to traditional AFSS, is that the flow rate is a constant value, and the irrigation intensity and extinguishing time are variable values. The article considers the influence of the distinctive features of the RFSS on the extinguishing parameters, the actual issues of the effective application of the RFSS, and provides a rationale for the optimal parameters of the RFSS, taking into account a differentiated approach in relation to the RFSS. The calculated data are given on the actual parameters of fire extinguishing of the RFSS, taking into account the assessment based on the actual test results. The possibility of algorithmization of the operation of the RFSS (stopping the extinguishing and checking the quality of the extinguishing) based on the condition of localization and elimination of fire at an early stage of fire development is shown.

Conclusions. Improving the technical means and algorithms for the operation of the RFSS allows to review the existing extinguishing parameters with the including of new parameters. The use of new parameters of the RFSS will significantly increase efficiency in terms of such as reducing flow rate, reducing extinguishing time, and reducing damage from a fire.
