Embodiment Construction

[0025] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0026] The idea of ​​the present invention is to realize the cross-ice wireless transmission of underwater data by using the cross-interface propagation performance of electromagnetic waves when propagating in layered conductive media, thereby avoiding the implementation difficulties of existing wired methods (sea ice buoys) and making up for It is difficult for underwater acoustic technology to directly cross the interface defects.

[0027] The idea of ​​the present invention can be combined with the attached figure 1 , attached figure 2 , attached image 3 To illustrate. In order to compare the difference and connection between the present invention and existing methods, appended figure 1 and 2 presents existing methods and techniques, with image 3 shows the method of the invention. Such as figure 1 As shown, the traditional cross-ice data transmissio...

Abstract

The invention relates to a cross-ice-layer data wireless transmission method, the frequency of an electromagnetic wave signal is low frequency and lower frequency, the frequency range is 0.5 kHz to 50kHz, and data terminals are respectively located at the depth within 10m in seawater below an ice layer and at an air layer above the ice layer. And the transmitting antenna adopts an electric dipoleantenna. And the receiving antenna adopts a magnetic antenna. The electric dipole antenna needs to be subjected to sealing and seawater corrosion prevention treatment, and seawater is prevented fromdirectly contacting with the metal part of the antenna. Electromagnetic wave signals are transmitted into the air after crossing the ice layer underwater, so that an electromagnetic wave-based data wireless transmission link in the underwater-ice layer-air is constructed, and data in seawater below the ice layer can be wirelessly transmitted into the air above the ice layer based on the link. Thereceiving antenna adopts a magnetic antenna, so that the detection sensitivity of electromagnetic wave signals can be improved, and the data transmission distance is increased. In addition, the electric dipole moment of the transmitting electric dipole antenna in seawater below the ice layer is increased, and the transmission distance in the air can be increased.

Description

technical field [0001] The invention belongs to cross-medium wireless communication, and relates to a method for wireless transmission of cross-ice layer data. Background technique [0002] Due to the rich energy and mineral resources in the north and south poles of the earth, especially the Arctic region has important military strategic value, it has gradually become a new frontier that affects the sustainable development of the world and human survival, and it is also a competition between major powers in the future around interests and influence. Therefore, it is urgent to carry out in-depth scientific research on polar seas. Underwater data such as marine environmental information are the basis for scientific research in polar seas. But much of the sea in the polar regions is covered by sea ice, making it difficult for underwater data to be efficiently transmitted across the ice. [0003] The wired method can realize the transmission of underwater data to the air above...
