A system and method for electromagnetic prospecting data acquisition

Abstract

The invention discloses a system and method for acquiring electromagnetic exploration data, wherein the system comprises an acquisition station, a reference station, a cloud station and a monitoring station, and the method comprises the following steps of: the cloud station is automatically connected through a wireless public network after the reference station is electrified, the electromagneticdata is acquired and the electromagnetic data is synchronously uploaded to the cloud station; the monitoring station acquires local electromagnetic data through a monitoring acquisition station of a local area network; after data acquisition is completed, the monitoring station downloads local electromagnetic data through the local area network, and then downloads reference electromagnetic data from the cloud station through the Internet or the wireless public network. The system and method for acquiring electromagnetic exploration data achieves the remote acquisition and recovery of the electromagnetic exploration data, reduces the arrangement and recovery times of the reference station, simultaneously utilizes the function of the monitoring station to network and monitor the acquisitionstation, ensures that all the acquisition stations can acquire qualified data, avoids repeated rework, improves field construction efficiency and data reliability, and the system and method for acquiring the near-far combined data are particularly suitable for acquiring electromagnetic exploration data.

Description

technical field [0001] The invention relates to the field of geophysical electromagnetic prospecting, in particular to a method and system for collecting electromagnetic prospecting data. Background technique [0002] Electromagnetic prospecting is a geophysical prospecting method that uses instruments to collect natural and artificial electrical and magnetic signals, and obtains underground mineral deposits and geological structures through signal processing. In order to improve the construction efficiency in the field, generally multiple collection stations will be deployed on the survey line to collect electromagnetic signals synchronously, and the deployment range is generally several hundred meters; at the same time, in order to improve the quality of signal processing, the survey line with multiple collection stations will be concentrated in the distance Find a place with less electromagnetic interference within the range of 10km to 500km outside to set up a reference ...

AI Technical Summary

Problems solved by technology

[0008] Based on this, aiming at the deficiencies of the prior art, the present invention provides a system and method for collecting electromagnetic survey data, which solves the problem that the data of the reference station cannot be recovered remotely and the data quality of the collection station cannot be monitored in real time in the field of electromagnetic survey. The corresponding information transmission optimization is carried out for the exploration data collection, so that the data transmission is more secure and reliable, and the data transmission efficiency is high
