Personnel recognition during belt conveyance
Abstract
A process is declared for the recognition of persons located on a continuous conveyor used in underground mines, in particular a conveyor belt, by which a running conveyor belt is monitored by means of video signals recorded by a stationary video camera, by means of which a person on the conveyor belt can be reliably and automatically recognized in a monitored danger area. Said process is characterized by the fact that video signals comprising the load condition of the conveyor belt (11) are generated by means of a light source (13) arranged vertically above the conveyor belt (11) for the emission of line light and a video camera (14) in the light section inclined at a lateral angle to the conveyor belt (11) and that, after the conversion of said video signals in an evaluation unit (17) into a suitable form for their processing by a computer, they are compared with each other over the consecutive length sections of the conveyor belt (11), and that, on deviation of the actual values abo ve a preset parameter, a signal is triggered to stop the conveyor belt (11).
