VIBRATION CONTROL DEVICE Russian patent published in 2017 - IPC G01M13/04 H05K3/36 

FIELD: radio engineering, communication.

SUBSTANCE: vibration control device contains at least two vibration sensors, each of which contains a piezoelectric element, at least two transducers and two, with increased rigidity, cables, each of which connects one of the vibration sensors to the corresponding transducer. Also it includes an electronic unit comprising at least two information and measurement channels, each of which is connected to the output of one of the transducers and consists of a bandpass filter, a scaling amplifier and a detector connected in series, the main output of which is connected to the inputs of the first and second comparators. The scaling amplifier and detector contain an additional output for outputting information to the interacting systems via an appropriate information link. There is a cross-board in the electronic unit containing the output communication lines of each of the information and measurement channels. All information and measurement channels are mounted on a common, common for them, printed-circuit board and are located in its opposite sections. The cross-board is perpendicular to the single printed-circuit board.

EFFECT: reducing the likelihood of false signals.
