Embodiment 1

[0026] See figure 1 , figure 1 It is a block diagram of a deep-sea video shooting and wireless transmission integrated system module provided by the embodiment of the present invention, including:

[0027] an illuminating device, configured to provide an illuminating light source of a first wavelength;

[0028] An image acquisition device, configured to acquire image information with the assistance of the illumination light source;

[0029] a signal sending device, configured to send the image information to a signal receiving device with a communication light source of a second wavelength;

[0030] The signal receiving device is used to receive the communication optical signal and output image information;

[0031] a display device for displaying the image information;

[0032] Wherein, the first wavelength is greater than the second wavelength.

[0033] In a specific implementation, the lighting device is generally an auxiliary light set in water or deep sea to illumina...

Embodiment 2

[0048] This embodiment demonstrates the solution of the present invention through an example. See figure 2 , figure 2 It is a schematic diagram of a specific example scenario provided by the embodiment of the present invention. In the example, two identical terminals are included. The distance between the two terminals is 9 meters, and the water quality attenuation coefficient in the pool is about 0.4m -1 .

[0049] Each terminal is composed of a deep-sea camera, a deep-sea light, a transmitter, a receiver, a switch, and a computer. The computer is located above the water surface, and the rest is located in the water. The various parts in each terminal are connected by watertight connecting wires.

[0050] The role of each component in the terminal is as follows:

[0051] Deep Sea Lights: Provides underwater lighting brightness. Using LED as the light source, the central wavelength is 470nm, the full width at half maximum of the spectrum is 30nm, and the luminous power...

Abstract

The invention discloses an integrated system for deep-sea video shooting and wireless transmission, comprising: an illumination device for providing an illumination light source with a first wavelength; an image acquisition device for collecting image information with the assistance of the illumination light source; signal transmission A device for sending the image information to a signal receiving device with a communication light source of a second wavelength; a signal receiving device for receiving a communication optical signal and outputting image information; a display device for displaying the image information; wherein, The first wavelength is greater than the second wavelength. An integrated system of deep-sea video shooting and wireless transmission of the present invention solves the interference problem of lighting lights by selecting a light source with a smaller wavelength than the lighting wavelength as the communication light source, and building an interference filter in the communication receiver, and can solve the problem of Deep-sea video shooting and real-time transmission problems.

Description

technical field [0001] The invention belongs to the field of underwater information transmission, and in particular relates to an integrated system of deep-sea video shooting and wireless transmission. Background technique [0002] The deep sea refers to the deep waters in the ocean, in this vast space there are rich biological and mineral resources. In recent years, with the increasing shortage of land resources, countries all over the world have increased the exploration and development of deep sea. However, due to the extreme water pressure of tens of megapascals or even hundreds of megapascals in the deep sea, humans cannot directly carry out work. Mobile platforms such as underwater vehicles (AUV) carry out deep sea operations. Moreover, as the difficulty of the operation increases, two or more mobile platforms often need to work together to efficiently complete the underwater operation task. [0003] In the process of close-range joint operations of deep-sea mobile ...
