Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] Such as figure 2 As shown, the present invention adopts a dual magnetic compass scheme. A set of built-in magnetic compass 105 is arranged inside the radio station 101, and a set of external magnetic compass 106 is arranged outside. The relationship between the built-in magnetic compass 105 and the sectors of the radio station 101 is fixed. The magnetic compass 106 is reasonably fixed and installed according to the actual situation; it can be connected to the radio station 101 through a cable or other equipment.

[0021] At the beginning of operation, turn off the radio control power amplifier and other high-current modules; let the system current be the minimum. At this time, because the system current is very small, the built-in magnetic compass 105 is less affected by the external environment, and it can be considered that its readings are accurate at this t...

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 [0001] The invention belongs to the field of magnetic compass in radio stations, and in particular relates to a device and a method for determining the azimuth angle of a sector in a radio station through a magnetic compass. Background technique [0002] In a radio station, sometimes it is necessary to calculate and determine the azimuth angle of the sector through a magnetic compass. The magnetic compass generally uses a geomagnetic sensor, which has strict environmental requirements. In order to ensure accuracy, it needs to stay away from ferromagnetic materials and large currents; Material selection to avoid the influence of ferromagnetic materials on sensor accuracy, but with the miniaturization of the equipment, the influence of the current in the equipment on the magnetic compass cannot be ignored (especially the current that changes when the power amplifier in the equipment is turned on and off). Generally use the method of external magnetic compass to...
