SEISMIC DETECTION SYSTEM Russian patent published in 2015 - IPC G08B13/16 G01V1/22 

FIELD: physics.

SUBSTANCE: disclosed system comprises detection means which include up to two seismic lines, and a group of seismic detectors included in a seismic line is merged into cells consisting of at least five piezoelectric seismic detectors arranged on two parallel lines by a matching amplifier combined with a bandpass filter, and one digital seismic detector connected thereto by analogue links, said digital seismic detector having a synchronisation output and input and also being equipped with a piezoelectric element, a matching amplifier combined with a bandpass filter, at least six conditioning amplifiers, a microcontroller and a linear transducer. The system also includes an electronic unit, which includes an input interface connected to seismic lines, a microcontroller and an output interface, and a connection switch box, wherein the electronic unit is connected by information links to the seismic lines and through the connection switch box, also connected to a power supply unit, to a central concentrator.

EFFECT: high noise-immunity and reliability, complete visual masking capacity and scalability.
