Abstract

A data analysis and monitoring system suitable for a marine geophysical prospecting towing cable comprises an oscillator data extraction module, a data core processing module, a command analysis module and a data reception module. The command analysis module analyzes the extraction ratio of configuration parameters. The data reception module deserializes and decodes earthquake acquisition data and towing cable state data. The data core processing module sends deserialized and decoded earthquake acquisition data and towing cable state data and corresponding analysis data to an external buffer. The oscillator data extraction module extracts the earthquake acquisition data and the towing cable state data and sends the data to the external for display.

Description

technical field [0001] The invention relates to a data analysis and monitoring technology, in particular to a data analysis and monitoring system suitable for marine geophysical exploration towlines. Background technique [0002] On the one hand, the high-density seismic data collected by the marine geophysical streamer system needs to be sent to the storage node for storage, and on the other hand, data extraction is required to monitor the data quality in real time, and the working status of the streamer system can be monitored by extracting the streamer status data. Existing data extraction is mainly realized by the hardware extraction module that comes with the AD converter. The extraction parameters are fixed, and the extraction rate of seismic data cannot be dynamically changed according to the instructions of the host computer. The ability to monitor the working status of the towline is insufficient. Contents of the invention [0003] The technical problem solved by...
