MULTICHANNEL ACOUSTICS-EMISSION ARRANGEMENT FOR ARTICLES CONTROL Russian patent published in 2007 - IPC G01N29/04 

FIELD: the invention is used for nondestructive control of articles.

SUBSTANCE: the essence is in that in the arrangement the output of an analog-digital converter is switched to the input of the first digital multiplexer whose control input is connected with the first output of the control device, the outputs of the first digital multiplexer are switched to two operating storage devices whose outputs are connected with the inputs of the second digital multiplexer and the control inputs of the operating storage devices are combined and switched to the second output of the control device, the third output of the control device is switched to the control input of the second digital multiplexer, and in each channel the output of a peak detector is connected with the non-invertible input of a comparator and the output of the digital-analog converter is switched to the non-invertible input of the comparator of each channel, the inputs of the digital-analog converters are combined and are connected to the first output of a microprocessor, the outputs of the comparators are connected with the inputs of the microprocessor whose input-output bus is connected with the first input-output bus of the control device, the second input-output bus of the control device is combined with the output bus of the second multiplexer and is connected with the bus of a computer.

EFFECT: increases quick-action and expands functional possibilities of the arrangement.
