SEISMIC COMMUNICATION DEVICE Russian patent published in 2017 - IPC G01V1/22 E21B47/14 H04B13/02 G08C17/02 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to radio engineering and can be used for tasks of geographic charting in engineering seismic survey. System for seismic communication containing seismic transmitters located in shaft development is disclosed, and seismic receiver installed on the Earth's surface, including N of seismic sensors, respectively form antenna array, N of amplifiers and the signal processing unit. According to invention, each of N seismic sensors is connected with switchboard through the corresponding amplifier, output of which is connected with the input of the microcontroller through analogue-to-digital converter, being the input of the signal processing unit, which comprises N random-access storage units, connected to the microcontroller through N-bit bidirectional bus, N controlled digital lines of delay, wherein each is connected by the input to the output of the microcontroller through N-bit bus, and by the output with appropriate input of adder one output of which is connected through signal/noise ratio meter, to the second input of the microcontroller, and by another output to decoder, one output of which is connected to the indicator, and by the second to the transmitting device.

EFFECT: increase in power of received signal and noise-immunity of transmission.
