Distributed high-precision seismic signal acquisition device and acquisition method

Abstract

The invention relates to a distributed high-precision seismic signal acquisition apparatus and an acquisition method thereof. The acquisition apparatus is characterized in that data transmission cables are connected to two ends of a pedestal; a protection shell is installed on the pedestal; an acquisition plate cabin is arranged inside the protection shell on the pedestal; an acquisition module is arranged in the acquisition plate cabin; and a detector input plug is arranged on the top of the protection shell. A feed system is coupled to a data communication module; with a 94-to-48-volt power supply coupled to the data transmission cables, a working voltage needed by the system is obtained by conversion, so that power supply of the whole link can be realized only by one power supply unit. With an ADS1282 analog-to-digital converter, the self-checking and system calibration are realized to guarantee high-fidelity, high-signal-to-noise-ration, high-resolution seismic signal acquisition. The method is simple and practical; the complicated process of field measurement is simplified; the time is saved; the field work intensity is reduced; the working efficiency of the field measurement is improved; and the field work cost is lowered.

Description

technical field [0001] The invention relates to a seismic signal acquisition device suitable for hybrid telemetry seismic exploration. In particular, a distributed design scheme and a high-performance wired communication protocol are adopted. In addition to meeting the high-precision seismic signal acquisition function, the seismic signal acquisition device also realizes Automatic cascading and high-speed high-reliability data communication. Background technique: [0002] Seismic prospecting method is the main method of mineral resources exploration. With the development of science and technology, the ability of this method to solve complex mineral geological problems is continuously enhanced. Seismic exploration instruments are the key equipment in seismic exploration methods. In the past 60 years, seismic exploration instruments have gone through five development stages: light spot recording seismograph, analog tape recording seismograph, digital seismograph, telemetry sei...

AI Technical Summary

Problems solved by technology

The communication between acquisition units mainly includes wireless communication technology, wired communication technology, and wired and wireless mixed mode. Although wireless communication technology can greatly reduce the weight of the equipment, it is limited by the bandwidth, communication distance and requirements of wireless communication technology. A large number of peripheral equipment and other conditions are limited, which cannot meet the needs of seismic exploration and field production
