Abstract

The invention discloses a marine geomagnetic daily variation observation device and a geomagnetic measuring method. The device comprises an observation boat and a plurality of floating main bodies arranged on the observation boat, wherein geomagnetic equipment is mounted on each floating main body; each floating main body comprises a positioning device, a driving device, a wireless communication device, a data processing device, a storage device and a power supply device; a control center is arranged on the observation boat; and the control center comprises a wireless communication unit, a data processing unit, a storage unit and an alarm device. The floating main bodies are launched in deep seas on latitude to be measured, and data collection is carried out on a geomagnetic field on the latitude without taking the observation boat as a carrier after magnetic field interference information of the floating main bodies is collected by a proton magnetometer, the observation is not restricted by an observation point, and the floating main bodies are quickly launched to a plurality of observation points, so that the efficiency of data collection is improved greatly.

Description

technical field

[0001] The invention relates to the technical field of marine geomagnetic field measurement, in particular to a marine geomagnetic diurnal variation observation device and a geomagnetic measurement method. Background technique

[0002] The geomagnetic field refers to the natural magnetic phenomenon that exists inside the earth. Marching and sailing use the effect of the geomagnetic field on the compass to orient themselves. People can also look for mineral deposits according to the distribution characteristics of the geomagnetic field on the ground. Changes in the geomagnetic field can affect the propagation of radio waves. When the local magnetic field is strongly disturbed by sunspot activities, long-distance communication will be seriously affected or even interrupted. If there is no geomagnetic field, the powerful stream of charged particles emitted from the sun (usually called the solar wind), it will not be deflected by the geomagnetic field, but direct...
