Abstract

FIELD: mining. SUBSTANCE: position indicator has two acoustic wave transmitters. There is one transmitter for each hoisting bucket. The indicator has also two emitters, two receivers and data processing unit including two wave mixers, reference generator, two frequency discriminators and two integrators. It is additionally equipped with two amplifiers and two instruments. As this takes place amplifiers' inputs are related to integrators' outputs, and amplifiers' outputs are related to instruments. EFFECT: higher reliability. 1 dwg

Изобретение относится к горному делу, а именно к области индикации при управлении шахтными подъемными машинами. Цель изобретения - повышение надежности и точности определения положения подъемных сосудов в стволе шахты. Для этого указатель, содержащий два передатчика акустических колебаний, по одному на каждом подъемном сосуде, два излучателя, два приемника и блок обработки информации, включающий два смесителя колебаний, опорный генератор, два частотных дискриминатора и два интегратора, дополнительно снабжен двумя усилителями и двумя измерительными приборами, при этом входы усилителей связаны с выходами интеграторов, а выходы - с измерительными приборами.The invention relates to mining, and in particular to the field of indication when controlling mine hoisting machines. The purpose of the invention is to increase the reliability and accuracy of determining the position of the lifting vessels in the shaft of the mine. For this, a pointer containing two transmitters of acoustic vibrations, one on each lifting vessel, two emitters, two receivers and an information processing unit, including two oscillation mixers, a reference oscillator, two frequency discriminators and two integrators, is additionally equipped with two amplifiers and two measuring devices , while the inputs of the amplifiers are connected to the outputs of the integrators, and the outputs are connected to measuring instruments.
