Abstract
This utility model provides the azimuthal equipment in sector in a kind of determination radio set, and including built-in magnetic compass and external magnetic compass, built-in magnetic compass is fixedly installed on inside radio station, and external magnetic compass is arranged at outside radio station.By increasing built-in magnetic compass, primary calibration is carried out, obtain the angle of external magnetic compass and radio station sector, so as to eliminate the restriction to external magnetic compass setting angle and position etc..
Description
Technical field
This utility model belongs to magnetic compass field in radio set, more particularly to one kind determines radio set by magnetic compass
The azimuthal device and method in middle sector.
Background technology
In radio set, it is sometimes desirable to calculate the azimuth for determining sector by magnetic compass, magnetic compass is generally used
Be geomagnetic sensor, the sensors towards ambient requires harsher, in order to ensure precision, needs away from ferromagnetic material and big electricity
Stream；Can avoid impact of the ferromagnetic material to sensor accuracy by material type selecting, but the miniaturization with equipment, equipment
Impact of the interior electric current to magnetic compass just very important (especially in equipment, the open and close of power amplifier cause the electric current of change), current one
As solve such problem using the external method of magnetic compass.But postpone outside magnetic compass, for the magnetic compass established angle for determining
Degree and the relation of sector, as shown in figure 1, general using the side for installing support bar in radio station shell or the first-class fixed position of support
Method.As the setting angle and position of radio station and external magnetic compass will be fixed, very dumb when causing to use, vehicle-mounted grade is applied
Scene brings very big restriction.
Utility model content
Technical problem to be solved in the utility model is to provide the azimuthal equipment in sector in a kind of determination radio set
And method, the setting angle and position of solution radio station and external magnetic compass will be fixed and be caused using inflexible problem.
Technical solution of the present utility model is：
The azimuthal equipment in sector in a kind of determination radio set, which is particular in that：Including built-in magnetic compass and outward
Magnetic compass is put, above-mentioned built-in magnetic compass is fixedly installed on inside radio station, above-mentioned external magnetic compass is arranged at outside radio station.
Above-mentioned external magnetic compass is connected by cable and radio station.
Above-mentioned external magnetic compass is positioned on the equipment for having communication connection with radio station, as long as external after ensureing upper electricity operation
The position in magnetic compass and radio station is relatively fixed, and the reading of external magnetic compass is passed to radio station by data transfer.
A kind of azimuthal method in sector in determination radio set, comprises the following steps：
Step one：Operation starts, and closes the high-current modules such as radio station power amplifier；
Step 2：The reading of built-in magnetic compass is read, the angle of now built-in magnetic compass and radio station sector is obtained；Read simultaneously
The reading of external magnetic compass is taken, the difference of reading of built-in magnetic compass and external magnetic compass is obtained；Calculate now external magnetic compass
Angle with radio station sector；
Step 3：The high-current modules such as radio station power amplifier are opened, built-in magnetic compass is stopped using；
Step 4：The reading of external magnetic compass is read, the external magnetic compass obtained in conjunction with step 2 and the folder of radio station sector
Angle calculates the azimuth of now radio station sector.
The beneficial effects of the utility model are：
1st, the utility model carries out primary calibration by increasing built-in magnetic compass, obtains external magnetic compass and radio station sector
Angle, so as to eliminate the restriction to external magnetic compass setting angle and position etc.；
2nd, the method is used, and external magnetic compass can also be put into indoor set or other and radio station the equipment of communication connection
On, radio station is passed to the reading of external magnetic compass by data transfer, as long as external magnetic compass and radio station relative angle after upper electricity
Constant with position, it is possible to which that the azimuth of radio station sector is obtained by the calibration of inside and outside magnetic compass, to improve the side for installing and using
Just property.
Description of the drawings
Fig. 1 is magnetic compass scheme of installation in prior art；
Fig. 2 is this utility model magnetic compass scheme of installation.
In figure, reference is：101- radio station；102- radio station support；103- magnetic compass support bars；104- magnetic compasses；105-
Built-in magnetic compass；The external magnetic compasses of 106-；
Specific embodiment
This utility model is further described below in conjunction with accompanying drawing.
As shown in figure 1, this utility model is using double magnetic compass schemes, 101 device interior of radio station arranges a set of built-in magnetic sieve
Disk 105, the relation of the outside sector that a set of external magnetic compass 106, built-in magnetic compass 105 and radio station 101 are set be fixed, outward
Put magnetic compass 106 rationally to be fixedly mounted according to practical situation；Which can be connected by cable or other equipment and radio station 101.
When operation starts, the high-current modules such as radio station control power amplifier are closed；Make system power minimum, now due to system electricity
Stream very little, built-in magnetic compass 105 receive external environment influence very little, it is believed that now its reading is accurate；Read simultaneously
Built-in magnetic compass 105 and the reading of external magnetic compass 106, obtain the angle a of built-in magnetic compass 105 and radio station sector and built-in
The difference of reading b of both magnetic compass 105 and external magnetic compass 106；By being calculated now external magnetic compass 106 and radio station sector
Angle c.Specific formula for calculation is as follows：C=a+b.
After normal work, power amplifier constant power is opened, and built-in magnetic compass 105 stops using, and reads now external magnetic compass
Reading, by the reading and back to external magnetic compass 106 be added with the angle c of radio station sector and be obtained normal work
When radio station in sector azimuth.
