SEISMIC SENSOR AND DATA COLLECTION DEVICE Russian patent published in 2016 - IPC G01V1/22 H04L7/04 H04L25/49 

FIELD: geophysics.

SUBSTANCE: invention relates to geophysics and can be used in seismic exploration. Disclosed is a digital seismic sensor (31) intended for connection via double-wire line (5) with data collection device (30). Digital seismic sensor comprises a digital sensor (311), local sampling pulse generator (317) providing sampling frequency, means (313) to receive control program, coming from data collection device, and information for synchronisation, providing accurate information on synchronisation to provide synchronisation of seismic sensors, means (312) for compensation, depending on information of synchronisation local drift sampling pulse generator; device for transmitting (314) seismic data to collection device data, a control device (312) for reception and transmission of signals over a half-duplex transmission via a two-wire line using transmission clock signals, extracted from acquired control program, means (315) to produce electric power supply and agent (318) for connecting means for receiving control program, means to transmit and receive electric power supply to two-wire line.

EFFECT: technical result is improved accuracy of obtained data.
