Description

Technical Field

[0001] The present application relates to the field of marine communication technology, and in particular to an ultra-large-range communication method and device for a fixed offshore platform. Background Art

[0002] For the transmission of radio waves, there is a huge gap between the atmospheric space and the underwater space. The interface between air and seawater (referred to as the water-air interface) is a natural barrier that isolates radio waves from entering the seawater across the interface. Because seawater is a conductive medium, radio waves will be severely attenuated in it. As a result, there is still no Internet, no mobile communications, no high-quality video, and even long-distance two-way wireless communication is almost non-existent in the underwater world of the vast ocean. This is really a great tragedy, because the ocean area occupies 71% of the earth's surface area and is vital to the economy, ecology, and human survival environment.

[0003] Over the past 100 years, people have made great efforts to try to find carriers that are conducive to transmitting information in seawater. At present, sound waves are still the best choice, which is better than radio waves, low-frequency electromagnetic waves and light waves (these three information carriers have advantages in certain specific scenarios). To illustrate the problem, here is a typical example - the attenuation of medium absorption and scattering when different carriers propagate in seawater: the attenuation of 1kHz ultra-low frequency electromagnetic waves (ULF, 300Hz~3kHz) propagating 100m is 110dB, and the attenuation of blue-green laser propagating 100m is 15.5~50.0dB; while the attenuation of 1kHz sound waves propagating 100km is only 7dB. In other words, if the propagation paths of the three carriers exist entirely in seawater, the propagation distance of sound waves will be more than 1,000 times higher than that of the other two carriers.

[0004] Microwave communications at sea have developed to a certain extent, but there are also some problems.

[0005] For example, there is the problem of multipath interference. There is a complex multipath propagation phenomenon in the marine environment, which causes interference and attenuation of the signal during transmission. This multipath interference seriously affects the communication quality and reliability of the fixed platform at sea. Another example is the lack of anti-interference ability. There are various interference sources in the marine environment, such as weather, sea conditions and other factors, which puts higher requirements on the microwave communication system. The existing technology still has certain limitations in terms of anti-interference ability. Summary of the invention

In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0035] An exemplary method for ultra-large-range communication of an offshore fixed platform in the present application comprises the following steps:

[0036] S10, splicing multiple antennas to distribute signals to multiple frequency resources;

[0037] By using multiple antennas for splicing, different signals are allocated to the same frequency resources and transmitted in different antennas, thus achieving high-speed transmission of ultra-large-range microwave communications.

[0038] S20, changing the transmission power to improve the signal strength and transmission distance;

[0039] Introduce high-power transmission technology to increase the strength and distance of signal transmission, and improve the coverage and transmission capacity of the communication system.

[0040] S30, setting an omnidirectional antenna to obtain an antenna structure with 360-degree omnidirectional coverage;

[0041] The omnidirectional antenna technology can achieve 360-degree coverage without dead angle communication. By optimizing the antenna structure and RF front-end circuit, all-round signal reception and transmission in the sea area around the offshore fixed platform are realized, improving the reliability and stability of communication.

[0042] S40, setting an adaptive beamforming mode to automatically adjust the direction of the transmit beam according to the position change of the receiving end and track the change of the target position;

[0043] This mode can automatically adjust the direction of the transmitting beam according to the change of the receiving end position, and track the change of the target position in real time during the transmission process. This adaptive performance enables the communication system to effectively adapt to the influence of factors such as waves and wind direction in complex marine environments, improving the reliability and stability of communication.

[0044] S50. An anti-interference antenna coordinator is set to ensure the stability of maritime communication signal transmission.

[0045] Some beneficial effects of the ultra-large-range communication method for offshore fixed platforms of the present application:

[0046] Communication range: The present invention adopts an omnidirectional antenna design to achieve 360-degree communication coverage without blind spots in the sea area around the offshore fixed platform, thus expanding the communication range.

[0047] Anti-interference capability: The present invention can enhance the communication system's resistance to various interference sources in the marine environment through anti-multipath interference algorithm technology, thereby improving the anti-interference capability.

[0048] Communication quality and reliability: The present invention can improve the communication quality and reliability through an anti-multipath interference algorithm, ensuring a stable and reliable communication connection in a complex marine environment.

[0049] In summary, compared with the prior art, the present invention has a wider communication range, higher data transmission rate and stronger anti-interference ability, while providing stable communication quality and reliability. This enables offshore fixed platforms to achieve ultra-large-range microwave communication and meet the demand for large-capacity data transmission in offshore applications.

[0050] In some preferred embodiments, step S30 includes setting a horizontal and vertical dual-polarization carrier receiving structure to form an omnidirectional antenna, and achieving reliable and stable signal reception and transmission through single polarization operation or dual polarization operation; and synthesizing dual-polarization dual-path signals to enhance the strength of the received signal;

[0051] Step S40 includes, S401, acquiring a position change of the opposite end in the link by receiving a positioning signal, and adaptively adjusting a built-in antenna deflector to switch a corresponding beam angle antenna;

[0052] S402, when the distribution angles of the mobile facilities are relatively concentrated, the beam width is reduced by using the antenna deflector to increase the antenna gain and obtain a longer coverage range;

[0053] S403. When the mobile facilities are distributed at a wide angle, the beam width is increased by using an antenna deflector to obtain a larger signal transmission range and reception range.

[0054] In steps S402 and S403, more concentrated distribution and wider distribution are a pair of mutually exclusive ranges. The concentration of the distribution angle is converted into an interval of 0-1, and it is defined that when the concentration is 0, the distribution angle concentration is the smallest, that is, the more dispersed the angle is; when the concentration is 1, the distribution angle concentration is the largest, that is, the more concentrated the angle is. In this application, the dividing line between concentrated distribution and wider distribution is set to 0.6, which means that when the distribution angle concentration is in the interval of 0-0.6, the distribution angle is wider; when the distribution angle concentration is in the interval of 0.6-1, the distribution angle is concentrated. The concentration of the distribution angle can be obtained by grouping the data according to the normal distribution, and then normalizing the data to obtain a decimal between 0-1.
