A Multi-working Mode Aircraft Spare Compass Calibrator

Abstract

The utility model relates to a spare compass calibrator with multiple working modes. It includes a housing and a partition installed on the housing, a magnetic sensor, a horizontal angle sensor, a processor module, a compass rotation knob, an observation window rotation knob, a magnetic heading cursor rotation knob, an observation window lock button, and a horizontal angle sensor orientation button , a reset switch, a rechargeable battery, a power switch, a charging interface, a raspberry pie module and an electronic display; the effect of the present invention is that it has the working modes of two current aircraft compass calibration devices, and the operation methods of the corresponding devices are consistent, and can realize two Switch between two working modes. The invention has short calibration time, low maintenance cost and strong portability; compared with the mechanical misalignment azimuth, the use of digital equipment can reduce the mechanical error, and the error can be calibrated in time through the algorithm, and the repeatability is strong, and the cost of updating is low. Low. It has the characteristics of simple equipment, convenient operation, fast detection speed, and little influence from the surrounding environment, so it is very suitable for on-site detection.

Description

technical field [0001] The invention belongs to the field of aviation airborne electronic equipment maintenance engineering technology, aviation maintenance practice teaching and training, and in particular relates to a multi-working mode aircraft spare compass calibrator. Background technique [0002] At present, the spare compass of the aircraft is installed above the center of the front windshield of the cockpit, and a magnetic strip sensor is used to measure the magnetic heading of the aircraft. Due to the metal structure of the airframe and electronic and electrical equipment, there is an additional magnetic field in the aircraft, that is, the aircraft magnetic field. The aircraft's spare compass measures the synthetic magnetic field of the aircraft's magnetic field and the earth's magnetic field, and there is an error in the obtained magnetic heading, that is, aberration. Therefore, the aircraft's spare compass needs to be checked and adjusted regularly to eliminate t...
