Pilot instrument based on solar-blind ultraviolet light signal

Abstract

The invention discloses a pilot instrument based on a solar blind ultraviolet light signal. The pilot instrument is composed of a triaxial electronic compass, an optical imaging module and an information processing terminal, wherein the triaxial electronic compass is connected with the optical imaging module, and is used for acquiring information of each angle of the optical imaging module in rotation, and transmitting the angle information to the information processing terminal, the optical imaging module is composed of a spectroscope, a visible light or infrared imaging channel and a solar blind ultraviolet imaging channel, the spectroscope is used for dividing an incident light into two beams according to a certain proportion or wavelength so that the two beams of light can respectively enter the visible light or infrared imaging channel and the solar blind ultraviolet imaging channel, the visible light or infrared imaging channel can be used for receiving a visible signal or infrared signal and outputting a visible light or infrared video digital signal, the solar blind ultraviolet imaging channel is used for receiving a solar blind ultraviolet signal and outputting a solar blind ultraviolet video digital signal, the information processing terminal is used for computing sailing posture data of a ship and outputting synthesis information according to the digital signals of two paths of videos.

Description

technical field [0001] The invention relates to the technology of ship piloting and mooring, in particular to a piloting instrument based on solar-blind ultraviolet light signals. Background technique [0002] The solar-blind ultraviolet band refers to the part of the ultraviolet UVC band with a wavelength range of 190-290nm. The solar-blind ultraviolet band light spots emitted by the sun are strongly absorbed by the ozone layer in the process of passing through the earth's atmosphere, and cannot reach the ground at all. Therefore, there is no solar-blind ultraviolet band light signal near the earth's surface in daily situations. Detectors in the solar-blind ultraviolet band have high gain and are not affected by the background of sunlight. Therefore, compared with visible or infrared light bands, solar-blind ultraviolet detectors can detect farther and weaker signals. At the same time, the images in the solar-blind ultraviolet band are relatively simple, and there is no en...

Problems solved by technology

[0006] For a long time, pilots have been using the most intuitive means of positioning, such as sight, to judge whether the ship is sailing in the channel by observing shore marks, buoys, etc., but visual observation is often affected by conditions such as visibility and light brightness. big limit
