FIELD: physics.
SUBSTANCE: structural scheme of seismic station includes sequence of seismic sensor, amplifier, analog-to-digital converter, active memory unit and digital-to analog converter, output of which serves as station output. Additionally the scheme contains voice support unit using delta modulation principle and consisting of microcontroller with n inputs, fixed memory unit, first-order RC integrator, sound frequency amplifier and speaker unit, connected in sequence. N inputs of microcontroller are initiating voice support unit and are connected to controlled parameter sensors of seismic station, while two control outputs of microcontroller are connected to clock input of analog-to-digital converter and address input of active memory unit respectively.
EFFECT: reduced defect rate and enhanced production efficiency.
