METHOD FOR VIOLATOR DETECTION AND VIOLATION PARAMETERS IDENTIFICATION Russian patent published in 2015 - IPC G08B13/00 

FIELD: electricity.

SUBSTANCE: invention consists in receipt of heat emission by two sensors placed at opposite boundary sides at the known distance from each other in direction along its lines. Received emission is converted to electrical signals characterizing duration of signals sensed by sensors since their commencement till their positive and negative maxima (t₁, t₂, Δt₁, Δt₂), as well as between commencement and positive maxima of the signal from two sensors (t₄, t₅). All potential alternatives of boundary crossing, being represented as the main population Ω, differ from each other by object size in regard to objective filed of view and position of movement pattern in regard to the boundary sides. Synthesis of class-division algorithm in the area of real events is based on search of the respective signs in the area of time responses occurring at emission receivers. An expert model is developed as a set of the above signs differentiating by discriminator functions, which allows on the basis of time interval analysis identification of the boundary-crossing alternative and parameters of crossing: longitudinal and transversal dimensions of the violating object, speed of its movement and position of the movement pattern in regard to secured (controlled) boundary. Based on estimation of the received parameters of the boundary crossing the decision adequate to general purpose of the system is taken: alarm signal is sent, violating objects are counted and sorted by size, etc.

EFFECT: improved interference resistance for violator detection due to analysis of violation parameters.
