Distributed data recovery method of cable-free storage seismograph

Abstract

The invention relates to a distributed data recovery method for a wireless storage type seismometer. The method comprises a triggering distribution method and a parallel recovery method of all sets of seismic data. Apart from collecting seismic data, a triggering station can record a focus triggering time mark; after exploration is completed, a hand-held terminal is used for recovering triggering time mark information in the triggering station, the scanning duration and the sampling rate are edited, and thus triggering information files are generated and are transmitted to all the sets through the Internet; each set is in charge of data recovery of a collecting station in the set, all the sets download data at the same time through a wired LAN, and after data recovery of all the sets is completed, the data are summarized to a data center. The problem that an existing data recovery mode can consume time and plenty of manpower and material resources is solved. Each set recovers valid data in the corresponding collecting station within the blasting time period according to the triggering time mark, the data are pre-processed, and rapid analysis is achieved. The data recovery period is greatly shortened, the stability and high efficiency of a data transmission link are guaranteed, seismic data quality is effectively guaranteed, and the outdoor working efficiency is improved.

Description

technical field [0001] The invention relates to a data recovery method of a cable-free storage seismograph in seismic exploration, in particular to a distributed data recovery method of a cable-free storage seismograph. Background technique [0002] The development of society has increased the demand for mineral resources. Seismic exploration technology, as a geophysical exploration method, has been widely used in coal field and engineering geological exploration, regional geological research and crustal research. A seismograph is an instrument used to record seismic waves in seismic exploration. In recent years, some domestic and foreign enterprises and research institutes have begun to develop a cable-free seismic acquisition system. This cableless seismic acquisition system adopts micro-acquisition station mode, cableless connection, single-station single-channel, and digital geophone acquisition; built-in GPS, which can be placed freely to overcome the influence of compl...

Problems solved by technology

During the seismic exploration process, we found that it takes a lot of manpower and material resources to arrange the seismometers on the survey line and recover them to the data center. At the same time, due to the huge amount of seismic data, the data recovery work is very time-consuming and cannot meet the needs in the exploration process. Quickly check the experimental results after each experiment to verify the data quality requirements
