Abstract
Description
Technical Field
[0001] The embodiment of the utility model relates to the field of ship technology, and in particular to a compass display system. Background Art
[0002] The gyrocompass uses a gyro ball or a fiber optic ring to achieve a guidance function that does not rely on a magnetic field. The azimuth compass is a repeater of the gyrocompass. The function of the azimuth compass is to display the 360° compass of the gyrocompass. The gyrocompass can be used in scenes where the direction needs to be determined. For example, the gyrocompass can be used in ship scenes. In ship scenes, the ship's bridge is usually located at the highest point of the ship, where the crew drives the ship. The azimuth compass is usually installed on both wings of the bridge to obtain a good line of sight, avoid blocking the observation of objects in the ship's environment, and facilitate the crew to determine the direction of objects.
[0003] At present, the crew usually observes the position of the object by vision based on the position compass. However, when the hull or the cargo stacked is higher than the bridge and blocks the crew's sight, the crew cannot observe the object whose position needs to be determined, resulting in the crew being unable to determine the position of the object in time.
