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

Embodiment 1

[0038]In order to make the technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0039] see figure 1 , a piloting and berthing system based on solar-blind ultraviolet light signals in foggy weather, which includes a solar-blind ultraviolet light source system 1 , a pilot instrument 2 and a display system 3 .

[0040] The solar-blind ultraviolet light source system 1 is composed of several solar-blind ultraviolet light sources 1-1. These solar-blind ultraviolet light sources are installed on both sides of the waterway, at the outline of bridges and dams, at ports and wharfs or on ships, etc., and are mainly used to identify targets The outline of the object, so that when it emits light, the observer can distinguish the object in front through the light pattern. The solar-blind ultraviolet light source is installed on the ship so that t...

Embodiment 2

[0070] This embodiment is basically the same as Embodiment 1, and the difference is that the navigator 2 is composed of a three-axis electronic compass 2-1, an optical imaging module 2-2 and an information processing terminal 2-4, that is, the navigator 2 does not include video acquisition Module 2-3, visible light or infrared light imaging channel 2-2-3 and sun-blind ultraviolet imaging channel 2-2-2 in the pilot instrument 2 directly output digital video to the information processing terminal 2-4, such as Image 6 shown.

Embodiment 3

[0072] A piloting and berthing system based on solar-blind ultraviolet light signals in foggy weather, which includes a solar-blind ultraviolet light source system 1 , a piloting instrument 2 and a display system 3 .

[0073] The solar-blind ultraviolet light source system 1 and the display system 3 are the same as those in Embodiment 1. The difference from Embodiment 1 is that the information output by the information processing terminal 2-4 in the pilot instrument 2 is not a synthetic video of solar-blind ultraviolet / visible light, but a real picture of pilot simulation processed by virtual reality technology.

[0074] In this embodiment, the auxiliary equipment 2-5 in the pilot instrument obtains the water transportation electronic chart or the three-dimensional electronic chart in real time through GPS or AIS, and transmits it to the information processing terminal. At this time, the information processing terminal 2-4 performs the following steps: 1) Acquire solar-blind u...

Abstract

A piloting berthing system based on solar-blind ultraviolet light signals comprises a solar-blind ultraviolet light source system, a piloting instrument and a display system. The piloting instrument comprises a tri-axial electronic compass, an optical imaging module and an information processing terminal. The tri-axial electronic compass is connected with the optical imaging module and is used for acquiring angle information of the optical imaging system during 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 light imaging channel and a solar-blind ultraviolet light imaging channel, wherein the spectroscope splits an incident ray into two beams to enable the two beams to enter the visible light or infrared light imaging channel and the solar-blind ultraviolet light imaging channel respectively, the visible light or infrared light imaging channel receives visible light signals and outputs visible light or infrared light video signals, and the solar-blind ultraviolet light imaging channel receives solar-blind ultraviolet light signals and outputs solar-blind ultraviolet light video signals. The signal processing terminal is used for calculating navigation attitude data of a ship and outputting synthetic video to the display system according to digital signals of two ways of videos.

Description

technical field [0001] The invention relates to the technology of ship piloting and berthing, in particular, relates to a piloting and berthing system 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,...
