Power-supply work station for seismic prospecting instrument and working method thereof

Abstract

The invention relates to a power-supply work station for a seismic prospecting instrument and a working method thereof. Compared with the prior art, the defect that a power-supply work station cannot integrate data acquiring, buffering, forwarding and power supplying is overcome. The power-supply work station comprises an FPGA (Field Programmable Gate Array) chip, a local power supply connected with the FPGA chip, a master SDRAM (Synchronous Dynamic Random Access Memory), a slavery SDRAM, a local data acquiring chip, a power supply management module and a network transformer, wherein the local data acquiring chip is connected with an acquisition driving module of the FPGA chip, the master SDRAM and the slavery SDRAM are respectively connected with an SDRAM ping-pong control module of the FPGA chip, and the network transformer is connected with a power supply control module of the FPGA chip via the power supply management module. According to the invention, data acquiring, buffering, forwarding and power supplying functions are integrated, a ping-pong buffering work mode is employed, and the work station and method are helpful for realization of large-scale seismic prospecting instrument systems, especially systems without limitations of channels.

Description

[0001] technical field [0002] The invention relates to the technical field of seismic exploration instruments, in particular to a power supply workstation for seismic exploration instruments and a working method thereof. [0003] Background technique [0004] For the location judgment of underground oil and minerals, explosives are used to enclose the measured area, and the material of underground substances is judged by the reflection data of sound waves generated after the explosion of explosives. This method requires that the data acquisition system in the seismic exploration instrument can accurately collect all kinds of data information reflected from the ground for later related research and analysis, so as to judge the underground material. Therefore, when the data acquisition device in the seismic exploration instrument is actually used, there are multiple data acquisition devices, which are distributed throughout the entire measured area, with a wide range and a ...
