Round three axis fluxgate magnetometer sensors are magnetic measurement sensing units, strong for the magnetic induction of inflight measurement earth's magnetic field Vector is spent in three axis components of sensor coordinate system, as a kind of attitude sensor under rate damping of entering the orbit, safe mode.Mark Fixed effect is to adjust magnetometer analog output and obtain itself and measurement magnetic field one-to-one relationship.
Currently, the caliberating device of round three axis fluxgate magnetometer sensors be by the assembling of orthogonal three faces and At volume is larger, in calibration process, can only pass through shifting when needing the biggish shielding space of other unit to carry out, and demarcating A face is moved to adjust magnetometer, makes magnetometer survey axis and shielding axis parallel, completes calibration.So in the prior art Caliberating device uses very inconvenient.
Utility model content
The purpose of this utility model is to provide a kind of for demarcating the device of round three axis fluxgate magnetometer sensors, To solve foregoing problems existing in the prior art.
To achieve the goals above, the technical solution adopted in the utility model is as follows:
It is a kind of for demarcating the device of round three axis fluxgate magnetometer sensors, including magnetometer positioning device, adjust Hemisphere and pedestal, are provided with arc groove on the pedestal, described to adjust hemispheroidal spherical surface bottom fitting and is placed on the arc In shape slot, the adjusting hemisphere can rotate in the arc groove, and the magnetometer positioning device is mounted on described adjust partly In the plane of sphere.
Preferably, the surface of the arc groove for adjusting hemispheroidal spherical surface and the pedestal is rough surface.
Preferably, the magnetometer positioning device is L-type, and the magnetometer positioning device is mounted on the adjusting hemisphere The edge of plane.
The beneficial effects of the utility model are: provided by the utility model pass for demarcating round three axis fluxgate magnetometers The device of sensor, including magnetometer positioning device, adjusting hemisphere and pedestal adjust hemispheroidal spherical surface bottom fitting and are placed on In the arc groove, adjusting hemisphere can rotate in arc groove.During the calibration process, hemisphere is adjusted by rotation, so that it may To realize the adjusting multi-faceted to the multi-angle of magnetometer, and the device of the prior art, only adjustable one side is therefore, and existing Device in technology is compared, and device provided in this embodiment can be more convenient and accurately makes magnetometer probe measurement axis and screen An axis parallel is covered, calibration is completed.Moreover, device provided in this embodiment, small in size, it is adapted to narrower inside shielding cylinder Small space, so, caliberating device provided in this embodiment can cooperate shielding cylinder to use, and no longer need to specifically shield empty Between, reduce external coordination expenditure and time cost.
Detailed description of the invention
Fig. 1 is the main view of caliberating device provided by the utility model;
Fig. 2 is the left view of caliberating device provided by the utility model;
Fig. 3 is the top view of caliberating device provided by the utility model.
In figure, the meaning of each symbol is as follows:
1 magnetometer positioning device, 2 adjust hemisphere, 3 pedestals.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing, to this reality It is further elaborated with novel.It should be appreciated that the specific embodiments described herein are only used to explain that this is practical It is novel, it is not used to limit the utility model.
It is passed as shown in Figure 1-3, the utility model embodiment provides one kind for demarcating round three axis fluxgate magnetometers The device of sensor, including magnetometer positioning device 1, hemisphere 2 and pedestal 3 are adjusted, it is provided with arc groove on the pedestal 3, institute The spherical surface bottom fitting for stating adjusting hemisphere 2 is placed in the arc groove, and the adjusting hemisphere 2 can be in the arc groove Rotation, the magnetometer positioning device 1 are mounted in the plane for adjusting hemisphere 2,
The device of above structure is used for the working principle of round three axis fluxgate magnetometer sensors calibration are as follows:
In calibration process, three axis fluxgate magnetometer sensors of circle are screwed on adjusting hemisphere first, During installation, magnetometer sensor is positioned by magnetometer positioning device, then, hemispheroidal bottom will be adjusted Spherical surface fitting in portion's is placed in the arc groove of pedestal, finally, putting the caliberating device into shielding cylinder after equipment is powered has voltage Value output, rotation adjust hemisphere, magnetometer survey axis and shielding cylinder axis parallel when output voltage maximum.
As it can be seen that device provided in this embodiment, adjusts hemisphere by rotation, so that it may realize the multi-angle to magnetometer One side is only adjusted in multi-faceted adjusting, and the device of the prior art, therefore, compared with device in the prior art, this implementation The device that example provides can be more convenient and accurately makes magnetometer probe measurement axis and shielding cylinder axis parallel, completes calibration. Moreover, device provided in this embodiment, small in size, it is adapted to compare narrow space inside shielding cylinder, so, the present embodiment The caliberating device of offer can cooperate shielding cylinder to use, and no longer need to specific shielding space, reduce external coordination expenditure and time Cost.
In the present embodiment, the surface of the arc groove of the spherical surface for adjusting hemisphere 2 and the pedestal 3 is rough surface.
Using rough surface, the frictional force adjusted between hemisphere and pedestal arc groove can be increased, so that device is being adjusted It is more stable in the process.
In the present embodiment, the magnetometer positioning device 1 can be L-type, and the magnetometer positioning device 1 is mounted on described Adjust the edge of 2 plane of hemisphere.
Using the above structure, the location and installation to magnetometer can have both been completed by positioning device, it is also possible that magnetic strength The contrast locating of meter is stronger, meanwhile, positioning device is mounted on and adjusts hemispheroidal edge, biggish space can be reserved and used In installation magnetometer.
