Integration and calibration method of geomagnetic vector measuring device for exploration

A geomagnetic vector measuring device for exploration, comprising:

• a magnetic vector measuring equipment main body comprising a cross-shaped frame structure, wherein a rotatable sleeve is arranged at a middle and lower part of a D-shaped vertical pipe of the cross-shaped frame structure;
• magnetic probes at upper and lower ends of the cross-shaped frame structure, wherein each of the magnetic probes is sealed in the cross-shaped frame through a cap plug;
• wherein a rotation relationship can be detected between three magnetic axis coordinates of each of the magnetic probes and three-axis coordinates of an attitude instrument, wherein the three magnetic axis coordinates are marked as (XM, YM, ZM), and the three-axis coordinates of the attitude instrument are marked as (Xz, Yz, Zz), and three axis of the attitude instrument are respectively a roll axis, a yaw axis and an azimuth axis;
• wherein the device is configured for correcting and calculating detected parameters, solving a polar angle and an azimuth angle of total magnetic field strength T in a spherical coordinate system of the D-shaped vertical pipe, then solving a polar angle and an azimuth angle of T in an attitude instrument coordinate system, and finally solving a polar angle and an azimuth angle of T in a geographical coordinate system;
• wherein the magnetic vector measuring equipment main body is configured such that:
• a D-plane of the D-shaped vertical pipe functions as a benchmark, and is configured to allow assembly of the cross-shaped frame in a middle part of the D-shaped vertical pipe by using two framing horizontal pipes;
• wherein a hole in a middle part of the D-shaped vertical pipe is configured to allow respectively sleeving two outer thin horizontal pipes on outer sides of the two framing horizontal pipes in the middle part of the D-shaped vertical pipe, and respectively fixing GPS antennas at upper ends of outer sides of the two thin horizontal pipes;
• and wherein an electromagnetic shielding cabinet can be fixedly installed at a position of the D-shaped vertical pipe meeting the framing horizontal pipes in a middle part of the cross-shaped frame, and wherein a magnetometer host, a recording system, an attitude instrument host and a power supply are installed in the electromagnetic shielding cabinet.
