LOW-NOISE LOW-FREQUENCY ANALOGUE SIGNAL RECORDER

摘要

FIELD: geophysics.;SUBSTANCE: invention relates to geophysics and can be used in solving problems of receiving waves of different physical nature in a geological environment, caused by natural and artificial sources, including seismological and seismic (microseismic) processes: solar-lunar high tides, typhoons, etc., hydrocarbon deposits , as well as technogenic processes, in particular, hydraulic fracturing of formation, machines, mechanisms and engineering structures in frequency range from tenths to hundreds of Hertz. Low-noise recorder of low-frequency analogue signal contains microcontroller main, microcontroller auxiliary, amplifier of registered signal, inputs of which are connected to sources of recorded signal, matching and filtering circuit, analogue-to-digital converter, clock frequency generator, GPS/GLONASS receiver, memory card, platinum resistance thermometer with measurement circuit, RS485 transceiver, wireless communication module and power circuit. Power circuit is configured to be connected to the storage battery, and the transceiver is configured to be connected to the wire communication line.;EFFECT: technical result is wider range of geophysical survey equipment, high reliability of recorded field material, wider range of applicability of equipment, its mobility and reliability during field use.;1 cl, 1 dwg
