Abstract
The invention provides a device for determining a sector azimuth in a radio station. The device comprises an inner magnetic compass and an outer magnetic compass, wherein the inner magnetic compass is fixedly arranged inside the station, and the outer magnetic compass is arranged outside the station. By adding the inner magnetic compass, an angle between the outer magnetic compass and a station sector can be obtained by virtue of one-time calibration, so that the limitation to an installation angle and position of the outer magnetic compass is canceled.
Description
Technical field
The invention belongs to magnetic compass field in radio set, particularly relate to one and determine radio set middle fan by magnetic compass
The azimuthal Apparatus and method in district.
Background technology
In radio set, it is sometimes desirable to calculated the azimuth determining sector by magnetic compass, magnetic compass generally uses
Be geomagnetic sensor, this sensors towards ambient requires harsher, in order to ensure precision, needs away from ferromagnetic material and big electricity
Stream；The ferromagnetic material impact on sensor accuracy can be avoided by material type selecting, but be as the miniaturization of equipment, equipment
Interior electric current on the impact of magnetic compass with regard to very important (especially in equipment, the open and close of power amplifier cause the electric current of change), current one
As use the external method of magnetic compass to solve such problem.But postpone outside magnetic compass, for the magnetic compass established angle determined
Degree and the relation of sector, use, as it is shown in figure 1, general, the side installing support bar in the first-class fixed position of radio station shell or support
Method.Owing to radio station and the setting angle of external magnetic compass and position to be fixed, the most dumb when causing using, wait application to vehicle-mounted
Scene brings the biggest restriction.
Summary of the invention
The technical problem to be solved is to provide one and determines the azimuthal equipment in sector and side in radio set
Method, solves radio station and the setting angle of external magnetic compass and position to be fixed and to cause using inflexible problem.
The technical solution of the present invention is:
One determines the azimuthal equipment in sector in radio set, and it is particular in that: include that built-in magnetic compass is with outer
Putting magnetic compass, above-mentioned built-in magnetic compass is fixedly installed on inside radio station, and 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 having communication to connect with radio station, external after operation as long as guarantee powers on
The position in magnetic compass and radio station is relatively fixed, and by data transmission, the reading of external magnetic compass is passed to radio station.
One determines the azimuthal method in sector in radio set, comprises the following steps:
Step one: run and start, closes the high-current modules such as radio station power amplifier；
Step 2: read the reading of built-in magnetic compass, obtains the most built-in magnetic compass and the angle of sector, radio station；Read simultaneously
Take the reading of external magnetic compass, obtain built-in magnetic compass and the difference of reading of external magnetic compass；Calculate the most external magnetic compass
Angle with sector, radio station；
Step 3: open the high-current modules such as radio station power amplifier, stop using built-in magnetic compass；
Step 4: read the reading of external magnetic compass, external magnetic compass that integrating step two obtains and the folder of sector, radio station
Angle calculates the azimuth of now sector, radio station.
The invention has the beneficial effects as follows:
1, this invention is by increasing built-in magnetic compass, carries out primary calibration, it is thus achieved that external magnetic compass and the folder of sector, radio station
Angle, thus eliminate the restriction to external magnetic compass setting angle and position etc.；
2, using the method, external magnetic compass can also be put into indoor set or other equipment having communication to connect with radio station
On, by data transmission, the reading of external magnetic compass is passed to radio station, if external magnetic compass and radio station relative angle after powering on
And invariant position, it is possible to the azimuth of sector, radio station, the side installed and used with raising is obtained by the calibration of inside and outside magnetic compass
Just property.

Fig. 1 is magnetic compass scheme of installation in prior art；
Fig. 2 is magnetic compass scheme of installation of the present invention.
In figure, reference is: 101-radio station；102-radio station support；103-magnetic compass support bar；104-magnetic compass；105-
Built-in magnetic compass；The external magnetic compass of 106-；
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described.
As it is shown in figure 1, the present invention uses double magnetic compass scheme, radio station 101 device interior arranges a set of built-in magnetic compass
105, outside arranges a set of external magnetic compass 106, and the relation of the sector in built-in magnetic compass 105 and radio station 101 is fixing, external
Magnetic compass 106 rationally fixedly mounts according to practical situation；It can be connected by cable or other equipment and radio station 101.
When running beginning, close radio station and control the high-current modules such as power amplifier；Make system power minimum, now due to system electricity
Flowing the least, built-in magnetic compass 105 is the least by external environment influence, it is believed that now its reading is accurately；Read simultaneously
Built-in magnetic compass 105 and the reading of external magnetic compass 106, obtain built-in magnetic compass 105 and the angle a of sector, radio station and built-in
The difference of reading b of both magnetic compass 105 and external magnetic compass 106；By being calculated the most external magnetic compass 106 and sector, radio station
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 is stopped using, and reads the most external magnetic compass
Reading, is added i.e. available normal work by the angle c of this reading and the external magnetic compass 106 arrived of back and sector, radio station
Time radio station in azimuth, sector.
