Abstract

The utility model provides a calibration device of a magnetic compass. The calibration device comprises a table surface, a table board, a nonmagnetic motor and a motor driver, wherein the table body and the rotary table surface are connected by a shaft; the motor is used for driving the nonmagnetic motor to drive the table surface to rotate; and all parts are nonmagnetic. Furthermore, the calibration device of the magnetic compass comprises a north-seeking device. Preferably, the nonmagnetic motor is an ultrasonic motor. Preferably, the shaft is a ceramic bearing. The calibration device of the magnetic compass can be used for calibrating the magnetic compass under the un-electric condition or the electric condition. Moreover, the calibration device of the magnetic compass is small in size, light in weight and easy to carry.

Description

A kind of calibrating installation of magnetic compass
Technical field
The present invention relates to a kind of calibrating installation of magnetic compass.
Background technology
Magnetic compass (north arrow) is used to indicate magnetic north, attaches it on the carrier.Accurately indicate the orientation of carrier.
But,, therefore between three error is arranged owing to can't accomplish vertically mutually between three of magnetic compass; Also have zero-error simultaneously, also there is deviation in mounting process, thereby causes error further to enlarge, and therefore need calibrate magnetic compass.
The Chinese utility model patent instructions of the CN201120299413.6 that on April 25th, 2012 was announced discloses a kind of magnetic compass spatial character calibrating installation.Device adopts fixed coil to produce calibration magnetic field, and magnetic compass is calibrated.This calibrating installation volume is big, is fit to the magnetic compass calibration of laboratory and fixed-site.
But a lot of occasions need be carried out field calibration to the magnetic compass on the equipment, and some occasion even can't provide power supply for calibrating installation, wish also that simultaneously the calibrating installation volume is little, in light weight, easy to use.
The utility model content
The utility model provides a kind of calibrating installation of magnetic compass at the problem that prior art exists, and can satisfy the calibration of not having electricity or magnetic compass under the electric situation being arranged, and whole device volume little, in light weight, be easy to carry about with one.
A kind of calibrating installation that is used for magnetic compass comprises table top, stage body, no magneto generator, motor driver, and stage body is connected by axle with rotary table top, and motor driver drives no magneto generator, drives the table top rotation; All parts are no magnetic.
Preferred no magneto generator adopts supersonic motor.Preferred axle employing ceramic bearing.
Further device also comprises north finding device.
Beneficial effect:
1) stage body is connected with rotary table top employing axle, realizes not having electricity and the calibration that has under the electric situation.
2) whole device adopts no magnetic design, can ignore as the stray magnetic field that no magneto generator, no magnetic material, assurance device produce, effectively assisted calibration magnetic compass pointing accuracy.
3) can provide the geographic orientation of table top automatically, improve the magnetic compass calibration accuracy.
4) utilize big terrestrial magnetic field that magnetic compass is calibrated, the device that produces magnetic field need not additionally be provided, thus volume little, in light weight, be easy to carry about with one.
Description of drawings
Fig. 1 is a system chart of the present invention.
Fig. 2 is a structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
A kind of calibrating installation of magnetic compass comprises: table top 102, and be used to put and put test product 101, test product is to comprise the equipment that magnetic compass is installed; Stage body 105 is used for supporting bable tops 102 and drives table top 102 rotations; Stage body 105 is connected by axle 104 with rotary table top 102, and stage body 105 drives table top 102 rotations.
No magneto generator 107, motor driver 108, motor driver 108 are realized the rotation of stage body 105 by the control to no magneto generator 107.
Aluminium alloy constitutes the main body of stage body, and fixture adopts the bronze gong nail between each parts, axle employing ceramic bearing.
No magneto generator adopts supersonic motor, and this motor utilizes piezoelectric effect that electric energy is converted into mechanical energy, the rotation of pushing motor axle, so run duration does not produce complementary field.
Because stage body 105 is connected by axle with rotary table top 102, under cold situation, manually revolving-turret realizes not having the electricity operation.
Also comprise north finding device, the geographic orientation of table top 102 is provided in real time.For the calibration of magnetic compass provides the orientation indication.
Though described embodiment of the present utility model in conjunction with the accompanying drawings, those skilled in the art can make various distortion or modification within the scope of the appended claims in this area.
