Problems solved by technology

However, the observation stations of marine geomagnetic diurnal variation are scarce, which leads to a decrease in the accuracy of ocean magnetic detection data in the open sea
[0004] In addition, since seawater is a conductor, seawater, currents, etc. have an important impact on the magnetic field distribution, and the daily variation observation data obtained by the submarine geomagnetic daily variation observation station will be distorted by the influence of the seawater layer, resulting in the inaccurate correction of the daily variation of the deep-sea magnetic measurement. completely, reducing the accuracy of ocean magnetic surveys

Abstract

The invention discloses a satellite transmission marine magnetic force detection device. In the detection device, seabed equipment is connected with sea surface equipment by virtue of an anchor system; the sea surface equipment comprises a sea surface satellite transceiving device and a sea surface data transmission device; the anchor system comprises an armour cable, an underwater floating body,a sea surface connecting piece and a seabed connecting piece; the seabed equipment comprises a seabed seismograph, a seabed data transmission device, a non-magnetic bottom anchor weight and an acoustic release transponder; and a seabed magnetometer and a total field magnetometer respectively acquire magnetic force signals at different depths in the sea and a magnetic force signal at a seabed in real time and send the magnetic force signals to a shore-based laboratory by virtue of the armour cable, the sea surface data transmission device and the sea surface satellite transceiving device sequentially, thus real-time detection on a seabed vibration signal is realized. The satellite transmission marine magnetic force detection device disclosed by the invention can improve open sea marine geomagnetic survey data accuracy of a research vessel.

Description

technical field [0001] The invention relates to the field of marine geophysical detection, in particular to a satellite-transmitted marine magnetic force detection device. Background technique [0002] Marine magnetic detection is an indispensable detection method for marine geophysical detection, and it is widely used in scientific research of seabed structure, exploration of marine oil and gas resources, ocean engineering, military target tracking and monitoring, etc. [0003] The current marine magnetic detection is mainly carried out by the towed method of the survey ship. Due to the interference of the solar diurnal change, the marine magnetic survey data of the survey ship must be corrected by the diurnal change before it can be used. However, there are few observation stations for marine geomagnetic diurnal variation, which leads to a decline in the accuracy of ocean magnetic detection data in the open sea. [0004] In addition, since seawater is a conductor, seawate...
