Problems solved by technology

The shortcoming of this patent is: when the animal moves freely, the attitude of its magnetoreceptor relative to the geomagnetic field is indeterminate, and its feeling to the strength and direction of the geomagnetic field is three-dimensional
However, the interference magnetic field generator only has a single axis, that is, the intensity and direction can only be adjusted in one direction, which inevitably limits the effect and applicable scenarios of magnetic field interference

Embodiment Construction

[0034] The present invention will be further described below in conjunction with accompanying drawing.

[0035] Such as figure 1 As shown, the three-axis magnetic field generating device suitable for birds includes: GPS module 1, power supply module, intensity and direction adjustment module 3, main control module 4, storage module 5 and three pairs of Helmholtz coils L. Among them, three pairs of Helmholtz coils are fixed on the head of the bird by brackets or caps. The axes of the coils are the axis between the ears of the bird, the vertical bird head, and the connection line between the beak and the back of the brain, while the other parts Mounted on the upper back of the bird. Three pairs of Helmholtz coils are connected with the magnetic field strength and direction adjustment module 3 of the three-axis magnetic field generator, the strength and direction adjustment module 3, the GPS module 1, the storage module 5 and the power module 2 are connected with the main contro...

Abstract

The invention provides a three-axis magnetic field generating device applicable to birds and a method for detecting the birds for magnetic navigation orientation by the aid of the three-axis magnetic field generating device. The three-axis magnetic field generating device and the method have the advantages that repeated release tracks are compared to terrestrial magnetism information of local magnetic maps, magnetic field interference conditions are preset in a master control module, received GPS (global positioning system) information is judged by the master control module when the birds such as pigeons fly to a certain specified region, current parameters of three pairs of coils in a three-axis magnetic field generator are started or changed, artificial magnetic fields in certain space directions are generated and interfere with (mislead or shield) perception terrestrial magnetism information, flight tracks of the birds are recorded and stored in real time, accordingly, tracking targets can be turned on and off at fixed points, magnetic field interference with variable three-dimensional directions and intensity can be carried out by the magnetic fields, flight movement track information of the birds such as the pigeons under artificial magnetic field interference conditions and non-interference conditions can be recorded and stored, and research on magnetic navigation behavior and mechanisms of the birds can be facilitated.

Description

technical field [0001] The invention relates to the technical field of electronic communication, in particular to a three-axis magnetic field generating device suitable for birds and a method for detecting magnetic navigation orientation of birds by using the device. Background technique [0002] Scientists have found through research that the geomagnetic field is an important factor affecting bird navigation, but how does the magnetic field affect the positioning and navigation of birds (especially under real flying conditions in the wild)? The total magnetic field of the earth is a vector field, and the rectangular coordinate system of the observation point is generally used to describe the spatial distribution characteristics of the magnetic field. There are four main elements namely the total strength of the magnetic field, the horizontal component, the magnetic field declination, and the magnetic inclination. It is a feasible experimental scheme to simulate real geomag...
