Embodiment Construction

[0035] The present invention will be described below in conjunction with the accompanying drawings.

[0036] No matter how complex the application of geophysical exploration instruments is and how different the environment is, the core function of the data recording system is the same, that is, to complete the recording and storage of seismic acquisition data. Although the front-end distributed sensor network has different forms and the types and quantities of sensors are different, the data communication between the sensor network and the recording system must be carried out through several cables. The difference in the scale of geophysical instruments will cause the number of these cables on the difference. In addition, the difference is reflected in the different data transmission methods on the cable, such as optical fiber or electricity, baseband or modulation, LVDS or Ethernet, etc. Therefore, according to the basic principle that the recording and transmission system r...

Abstract

The invention relates to a common data recording system architecture for geophysical exploration and a constructing method of the architecture. The system architecture comprises a plurality of cable data drivers, a system monitoring module, a recording and storage module and a daily and monthly inspection data processing module. Each cable data driver is respectively connected to the system monitoring module and the recording and storage module through to Ethernet interfaces so as to achieve cable data monitoring and recording and storage. Each cable data driver is connected to the daily and monthly inspection data processing module through a high-speed serial interface. The daily and monthly inspection data processing module combines and processes daily and monthly data output by the cable data drivers, synthesizes the combined processed results and the cable data recording and storage results of the recording and storage module to perform daily and monthly data analysis. The system architecture is high in data transmission capability, flexible in configuration, high in expansion capability, simple in structure and capable of increasing reliability and working efficiency.

Description

technical field [0001] The invention relates to the technical field of geophysical prospecting, in particular to a general data recording system architecture and construction method for geophysical prospecting. Background technique [0002] Seismic exploration is the most commonly used effective method among various geophysical exploration methods such as petroleum and geology. In such methods, artificial methods are usually used to excite seismic waves, and geophysical instruments collect seismic wave signals through an array of sensors (such as moving coil geophones for land, piezoelectric ceramic hydrophones for sea), and collect and record them. . During land exploration operations, the data is collected through scattered collection stations, and then the cross station is used to transmit the data to the host computer in the instrument vehicle for recording; during marine geophysical exploration operations, several piezoelectric The cable array of ceramic hydrophones m...
