Survey instrument function.At this point, gyroscope need to be dismantled down, it is placed on special test turntable, rotating table, generates turning rate input
It is tested, process is cumbersome.Simultaneously because it can not equip after installation and carry out further confirming that for performance using preceding, to dress
Standby use brings hidden danger.
Summary of the invention
In place of making up the deficiencies in the prior art, providing one kind can be realized instrument angular velocity measurement
The gyroscope torque with self-checking function of function.The present invention realizes under no angular speed input condition, inertia type instrument pair
The self-test of angular speed sensibility.
The purpose of the present invention is what is realized by following technological means：
A kind of gyroscope torque with self-checking function, including interior magnetic guiding loop, dynamic cup, magnetic pole of the stator and coil, it is interior
The inside of dynamic cup is arranged in magnetic guiding loop, and coil is arranged on dynamic cup, it is characterised in that：The lateral wall of interior magnetic guiding loop is along the circumferential direction equal
Cloth installs multiple magnetic pole of the stator, and gyroscope outer housing is arranged in the outside of dynamic cup；The quantity and stator magnet number of poles of dynamic cup coil
Measure identical, be divided into two parts, a part is torquer main coil, the torquer main coil be it is multiple, series connection is drawn and is used for
Generate the feedback moment in circuit；Another part be torquer secondary coil, the torquer secondary coil be one or more, list
It solely draws or series connection is drawn, the self-checking function of instrument angular velocity measurement can be achieved after energization.
Moreover, the magnetic pole of the stator is at least six.
Moreover, the gyroscope outer housing is made of soft magnetic materials.
Moreover, the interior magnetic guiding loop, dynamic cup and gyroscope outer housing are coaxial arrangement.
The advantages and positive effects of the present invention are：
1, the present invention is improved for Gyroscope of Single Degree of Freedom with torquer, by moving cup coil to torquer
It is changed with the structure of magnetic pole of the stator, realizes instrument function self-checking function, solve that instrument is undetectable in system to ask
Topic.
2, design science of the present invention, improve rationally, be easily achieved, only torquer structure need to be improved, without
Increase other new constructions, on the basis of original structure, realizes required function.
3, magnetic pole of the stator is fixed on interior magnetic guiding loop by the present invention, uses soft magnetic materials as gyroscope outer housing, substitution
Outer magnetic guiding loop.After removing outer magnetic guiding loop, the volume of torquer can be reduced, provide support for the miniaturization of instrument.
4, the present invention be a kind of design rationally, the gyroscope torque with self-checking function of scientific structure, this torque
Device has achieved the purpose that self-test, has solved instrument and exist by improving in the structure and quantity to coil and magnetic pole of the stator
Undetectable problem in system eliminates the use hidden danger of equipment.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that existing liquid floats inertia type instrument torquer；
Fig. 2 is that existing torquer moves cup coil-winding figure；
Fig. 3 is the structural schematic diagram of self-test torquer proposed by the present invention；
Fig. 4 is that self-test torquer proposed by the present invention moves cup coil-winding figure.
Specific embodiment
With reference to the accompanying drawing in detail narration the embodiment of the present invention, it should be noted that the present embodiment be it is narrative, no
It is restrictive, this does not limit the scope of protection of the present invention.
Improvements to facilitate the understanding of the present invention are first briefly described existing torquer structure：
Fig. 1 is that existing liquid floats inertia type instrument moving-coil type torquer structure, including magnetic pole of the stator 2 (four), dynamic cup 4, interior leads
Magnet ring 3 and outer magnetic guiding loop 1.Fig. 2 is that existing torquer moves cup coil-winding figure, it can be seen from the figure that existing torquer coiling
It is to be connected in series to four coils 5.Above structure is mounted on system as angular velocity measurement device in the presence of when gyroscope
It, can not be in the case where not starting equipment the problem of detection instrument function on platform.
A kind of gyroscope torque with self-checking function, including interior magnetic guiding loop 3, dynamic cup 4, magnetic pole of the stator 2 and coil
5, the inside of dynamic cup is arranged in interior magnetic guiding loop, coil is arranged on dynamic cup, the lateral wall of interior magnetic guiding loop is along the circumferential direction uniformly installed
Multiple magnetic pole of the stator, magnetic pole of the stator are at least six.By increasing the quantity of torquer magnetic pole of the stator, to reduce due to distributing to
The loss of torquer scale caused by secondary coil.
The quantity of dynamic cup coil is identical as magnetic pole of the stator quantity, is divided into two parts, and a part is torquer main coil,
The torquer main coil be it is multiple, series connection draw for generating the feedback moment in circuit；Another part is torquer by-pass
Circle, the torquer secondary coil are one or more, individually draw or connect and draw, instrument angular speed can be achieved after energization
The self-checking function of measurement.
As shown in Figure 3 and Figure 4, torquer magnetic pole of the stator quantity is changed to six in the present embodiment, is mounted on interior magnetic guiding loop.
Since one group of coil out to be separated is used to detect instrument function, in order to not influence torquer scale, by coil sum by original
Four increase to six, wherein five series connection, which are drawn, is used as torquer main coil, individually draws for remaining one and are used as torquer pair
Coil.If the size of current and detection range when to torquer scale or self-test can further adjust line there are other requirements
Circle sum and main and sub-coil ratio.
Gyroscope outer housing 6 is set in the outside of dynamic cup, which is made of soft magnetic materials.Described is interior
Magnetic guiding loop, dynamic cup and gyroscope outer housing are coaxial arrangement.
Coil on dynamic cup is divided into two groups by the present invention, i.e., for generating the feedback moment in circuit, referred to as main coil；
Another group is referred to as secondary coil.By applying electric current to secondary coil, torque is generated, pulls float to deflect, thus analog meter
Table has state when turning rate input, detects size of current in torquer main coil at this time, judges instrument function.
