Abstract

The invention discloses a device and system for collecting seismic data, and the device comprises a single detector which comprises a sensor core body for sensing a vibration wave, an interface circuit which enables a vibration wave to be converted into a signal representing a vibration parameter, and a collection control module which is used for receiving the vibration parameter signal and enabling the vibration parameter signal to be encoded into data at a certain format. The collection control module also comprises a communication circuit, so as to enable all coded data to be transmitted outwards. The device also comprises a storage unit, and the storage unit is in communication connection with the detector so as to receive and store the coding data transmitted by the detector. Meanwhile, the invention also provides a system for collecting seismic data, wherein the system employs a plurality of devices provided by the invention. The device and system reduce the wiring workload, improve the accuracy of data transmission and exploration precision, and can achieve the real-time positioning of the collection position of seismic data collection.

Description

technical field [0001] The invention relates to the technical field of geophysical exploration, in particular to a field data acquisition device and system for geophysical exploration. Background technique [0002] Geophysical exploration is usually divided into three stages: field data acquisition, seismic data processing and seismic data interpretation. The field data acquisition stage is to use seismic exploration instruments to generate seismic waves by artificial excitation on the surface. The seismic waves propagate underground. When encountering the stratum, they return to the surface in different ways such as direct waves and reflected waves to be received by the ground receiving equipment and recorded at the same time. Field Seismic Records. These field seismic records are the original basis and working basis for seismic data processing and seismic data interpretation. [0003] Seismic exploration instruments are special equipment used to directly record and colle...
