SEISMIC DATA COLLECTION SYSTEM Russian patent published in 2022 - IPC G01V1/22 

FIELD: seismic research.

SUBSTANCE: invention relates to the field of seismology and more specifically to a system for collecting seismic data and can be used in automated systems for collecting geophysical information, in particular in multi-channel digital telemetry seismic recording systems with wired and wireless communication lines. A seismic data collection system is proposed, containing a data collection unit, a control computer, a unit of seismic receivers, a recording unit containing a memory unit located together with a unit of seismic receivers. According to the invention, the system additionally contains concentrator units interconnected by a fiber-optic cable and with a control computer. The data acquisition unit contains cable modules and cable-free units made with the possibility of synchronous operation from the satellite signal, while the number of cable modules and cable-free units is determined by the number of seismic channels. Each of the concentrators is equipped with a controlled cable line power supply and a module for converting an optical signal into a digital signal and vice versa and has an input for connecting to a cable module, for connecting Wi-Fi antennas, for receiving a signal from a cable-free unit via a radio channel, for a GPS antenna, for connecting a battery. At the same time, each concentrator contains a processor programmed with the ability to compress signals coming from cable modules and cable-free units, and the number of concentrator units is selected depending on the number of seismic channels.

EFFECT: lengthening the line of arrangement to 2400 active seismic channels during 2D work and providing 3D mode for areal field work with a channel capacity of up to 100,000 active seismic cable and cable-free channels.
