Abstract

The invention discloses a marine streamer seismic data acquisition device, aiming at overcoming the defect of poor real-time performance of a control system in the traditional marine streamer seismic data acquisition process. The device comprises a command processing module, a data sending module and a network monitoring module, wherein the command processing module is used for receiving a main control command sent by a main control work station and sending a command response to the main control work station after processing the task of the main control command; the data sending module is used for establishing a seismic data client during initialization, receiving seismic data sent by an acquisition system by using the seismic data client after initialization, and sending the seismic data to a drawing and recording work station; and the network monitoring module is used for monitoring a command channel between the command processing module and the main control work station and monitoring a data channel between the data sending module and the drawing and recording work station. Compared with the prior art, the technical scheme of the invention effectively improves the real-time performance of command transmission and the efficiency of data transmission.

Description

technical field [0001] The invention relates to a seismic data acquisition technology, in particular to a seismic data acquisition device for a sea streamer. Background technique [0002] In seismic exploration and acquisition equipment, the amount of seismic acquisition data that needs to be transmitted continues to increase. With the refinement of exploration and development, generally speaking, seismic exploration methods are developing in the direction of multi-dimensional, multi-component, super multi-channel, etc., which also determines the stability and reliability of seismic exploration acquisition equipment for data transmission. constantly improving. [0003] Due to the different requirements and the limitation of equipment hardware capabilities by the technical conditions at that time, for the current seismic exploration and acquisition equipment, there is a certain bottleneck in the real-time performance of the existing control system, and it cannot well meet th...
