Abstract

Aiming at the characteristics of under ground acoustic telemetry system（ ATS）

using fixed-frequency acoustic pulse as signal transmission means

a new type of ground surface fixed-frequency signal acquisition device is designed by using the resonance principle. The Abaqus finite element method is used for modal analysis design and harmonic response analysis

it proves that the fix-frequency signal acquisition device has good frequencyselection characteristic. Through the comparison test between the LGT—20D40 moving coil geophone and INV9828 piezoelectric acceleration sensor

verify the advantages in sensitivity and anti-interference ability. It is proved by field application test that it can greatly improves the success rate of ground decoding and has practical value. The designed fixed-frequency signal acquisition device provides a new method to solve the problem of difficult ground decoding of the underground ATS

and it can also be applied to similar occasions.
