Experimental Tests of Flame Control High-Speed Multipoint Electro-Optical System


The new principle was developed related to constructing multipoint electro-optical system for a flame detection based on the total of non-coordinate electro-optical gauges located in a special way at a protected technogenic facility. Such an approach allows to detect the flame and determine its spatial coordinates throughout the whole volume of the protected premise of the complex geometric shape with the required accuracy and high speed. 

Technical principle for multipoint electro-optical system functioning and non-coordinate electro-optical gauges, which are part of it, was developed, and the electro-optical system prototype was created. Optimal spectral ranges were defined for controlling radiation, and the relevant radiation sensors were selected taking into account the compensation method for optical noise suppression in the non-coordinate electro-optical   gauges. Approaches are given to the experimental study of the key technical parameters of the system, which is based both on the new methods of studying the error of defining spatial flame coordinates in the conditions close to the actual operating one. The new methods are based on the organization of a volumetric test bench with specially placed test firer sources of various types, which allows to establish the influence of the zone of flame location on the control accuracy.

Determination of the source of fire detection is studied by measuring the maximum distance to the test fire seat, at which there is a stable gauge actuation. Determination of the viewing angle is defined based on the gauge sensitivity diagram. Study of the multipoint electro-optical noise immunity gauges is studied based on the optical interference in the form of incandescent lamps radiation, and the heated bodies both at the simultaneous effect of the useful signal (flame) and in its absence. The system technical parameters were defined from five non-coordinate electro-optical gauges. The obtained results satisfy the requirements for the flame control system and confirm the correctness of the proposed principles of system constructing, as well as the applicability of the method for determining flame spatial coordinates.
