Description

Technical Field

[0001] This invention relates to the field of marine communication equipment technology, specifically to a Tiantong Beidou dual-mode communication positioning pressure-resistant terminal device. Background Technology

[0002] Current underwater vehicles, taking underwater gliders as an example, mostly use a communication method where the communication terminal is placed inside a pressure-resistant hull. The signal is transmitted from an external antenna through a watertight radio frequency cable back to the communication terminal inside the pressure-resistant hull. The excessively long watertight radio frequency cable and radio frequency watertight connection components not only increase the cost of the equipment, but also cause significant attenuation of the communication signal.

[0003] When a redundant communication scheme with multiple communication terminals is adopted, in addition to the equipment cost increasing several times, the number, weight, and drainage volume of watertight cables, watertight connectors, and watertight antennas of the communication positioning terminal equipment will also increase accordingly, which will affect other physical indicators of the underwater vehicle, such as hydrodynamic parameters, carrying capacity, and communication displacement.

Detailed Implementation

[0023] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0024] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by those skilled in the art to which this invention pertains.

[0025] See Figures 1-4 This application discloses a Tiantong Beidou dual-mode communication and positioning pressure-resistant terminal device, including an antenna assembly, a pressure-resistant cabin assembly, an antenna intermediate rod 4, and a cabin penetration component 11. The antenna assembly is offset from the axis of the pressure-resistant cabin assembly. One end of the antenna intermediate rod 4 is connected to the antenna assembly, and the other end of the antenna intermediate rod 4 is connected to the pressure-resistant cabin assembly. The antenna assembly includes an antenna protection body and a radiator 2 disposed within the antenna protection body. The pressure-resistant cabin assembly includes a pressure-resistant cabin and a communication module 7 disposed within the pressure-resistant cabin. The radiator 2 is connected to the communication module 7 via an RF cable passing through the antenna intermediate rod 4. One end of the cabin penetration component 11 is inserted into the pressure-resistant cabin, and the other end extends out of the pressure-resistant cabin.

[0026] This application integrates the communication module 7 with the antenna by setting up a pressure chamber for installation, making the communication module 7 an independent module outside the underwater vehicle body. This is beneficial for the modular and modular design of the underwater vehicle, and also shortens the length of the radio frequency cable between the communication module 7 and the radiator 2, reducing the cost of raw materials, reducing radio frequency signal attenuation, and shortening the assembly time of the components without weakening the functionality.

[0027] The antenna assembly is located above the pressure-resistant chamber assembly, and the two are connected by the antenna intermediate rod 4 at a 90-degree angle.

[0028] The antenna protector has a flat structure, which includes an antenna base 3 and an antenna cover 1 connected to the antenna base 3. The radiator 2 is disposed between the antenna base 3 and the antenna cover 1, and its upper side is in close contact with the antenna cover 1.

[0029] Specifically, the radiator 2 is the radiator 2 of the Tiantong Beidou Iridium six-band deep-sea pressure-resistant composite antenna. This radiator 2 is made of a rigid pressure-bearing material, participates in pressure resistance, and provides support for the antenna protective cover 1. The radiator 2 has a flat structure, including a base 12 and protruding portions 13 extending from both sides of the base 12. Both the base 12 and the protruding portions 13 are rectangular structures, with the protruding portions 13 located in the middle of the base 12. In this embodiment, there are two bases 12 and two protruding portions 13, with the two bases 12 arranged side by side and the two protruding portions 13 respectively located on both sides of the corresponding base 12.

[0030] The radiator 2 can support the antenna cover 1, so the thickness of the antenna cover 1 can be designed to be thinner, thereby reducing the antenna's drainage volume, weight and cross-sectional area in the direction of underwater vehicle movement. Under the same buoyancy, the signal stability during communication is better.

[0031] The radiator of the Tiantong Beidou Iridium six-band deep-sea pressure-resistant composite antenna includes six frequency bands: Tiantong communication band, Beidou short message transmission band, Beidou short message reception band, Iridium communication band, Beidou positioning B1 band, and GPS positioning L1 band.

[0032] The antenna protective cover 1 is located above the radiator 2 and is made of PEEK material, which has low signal attenuation. The inner side of the antenna protective cover 1 is provided with a first groove 8 that mates with the base 12. The inner side of the antenna base 3 and the first groove 8 are respectively provided with second grooves 14 that mate with the outward protrusions 13. The base 12 is embedded in the first groove 8, and the outward protrusions 13 on both sides of the base 12 are correspondingly embedded in the second grooves 14, so that the radiator 2 fills the antenna protective body and is in close contact with the antenna protective body, supporting the antenna protective body to withstand seawater pressure.

[0033] Multiple connection holes are provided at intervals along the circumference of the antenna protective cover 1 and the antenna base 3. The two are connected by screws passing through the connection holes to press the radiator 2 tightly. An O-ring is also provided between the antenna protective cover 1 and the antenna base 3 to achieve a sealed connection between the two.

[0034] Communication module 7 is one or two of the following: Tiantong Beidou communication and positioning module, Beidou short message communication module 7, or Iridium communication module 7.

[0035] The pressure tank is made of titanium alloy, which is lightweight underwater and has a small displacement volume. It can save energy while ensuring pressure resistance, making it ideal for underwater equipment. Depending on cost or installation requirements, aluminum alloy or stainless steel can be selected.

[0036] The pressure chamber includes a pressure chamber body and a pressure chamber fixing ring 10. The pressure chamber body is fixed inside the pressure chamber fixing ring 10. The pressure chamber body has a receiving cavity, and the receiving cavity has a fixing bracket 6 for installing the communication module 7. The communication module 7 is installed on the fixing bracket 6.

[0037] Specifically, one end of the pressure chamber fixing ring 10 is open, and an elastic slot is provided at the open end of the pressure chamber fixing ring 10 along its axial direction. Multiple elastic slots are provided at intervals around the open end of the pressure chamber. The pressure chamber body is inserted into and fixed inside the pressure chamber body through the open end of the pressure chamber fixing ring 10. After the pressure chamber body is inserted into the pressure chamber fixing ring 10, a hose clamp can be used to tighten the open end of the pressure chamber fixing ring 10.

[0038] The main body of the pressure tank includes a pressure tank shell 9 and a pressure tank end cap 5. The accommodating cavity is located inside the pressure tank shell 9, and one end of the pressure tank shell 9 is open. The pressure tank end cap 5 is fixed to the open end of the pressure tank shell 9 by screws. An O-ring is also provided between the pressure tank end cap 5 and the pressure tank shell 9 to achieve underwater sealing connection.

[0039] The mounting bracket 6 can secure one or two communication modules 7. Its structure is preferably designed to facilitate the securing of the communication modules 7. Depending on the selected communication modules 7, the structure of the mounting bracket 6 can be modified accordingly. The mounting bracket 6 is located inside the accommodating cavity, with one end threadedly connected to the pressure-resistant chamber end cover 5, supporting the loaded communication modules 7 and preventing them from being bumped or knocked.

[0040] The penetration component 11 is located at the end furthest from the pressure hull end cover 5, and is sealed to the pressure hull 9 by an O-ring. One end of the penetration component 11 is inserted into the receiving cavity, and the other end extends out of the pressure hull. The penetration component 11 is used for power supply and information transmission between the communication module 7 and the control computer inside the underwater vehicle.

[0041] The antenna intermediate rod 4 is a long columnar structure with a wiring channel along its length. A connecting post is located on the outer side of the pressure-resistant chamber end cover 5. This connecting post is radially arranged along the pressure-resistant chamber end cover 5 and has a first wiring hole communicating with the accommodating cavity. A second wiring hole is provided on the antenna base 3. The upper end of the antenna intermediate rod 4 is welded to the antenna base 3, and the upper end of the wiring channel corresponds to the second wiring hole. The lower end of the antenna intermediate rod 4 is welded to the connecting post on the outer side of the pressure-resistant chamber end cover 5, and the lower end of the wiring channel communicates with the first wiring hole. The pressure-resistant chamber end cover 5 and the antenna base 3 are welded together as a single unit via the antenna intermediate rod 4.

[0042] The radio frequency cable of the radiator 2 passes through the second cable hole, the line channel and the first cable hole in sequence and is connected to the corresponding communication module 7 for the transmission of signals.

[0043] The pressure chamber fixing ring 10 has a flange at the bottom. After the pressure chamber is tightened, the Tiantong Beidou dual-mode communication positioning pressure-resistant terminal equipment is fixed to the body of the underwater equipment.

[0044] The Tiantong Beidou dual-mode communication and positioning pressure-resistant terminal equipment of this application can be unloaded and assembled with the underwater vehicle as a separate unit, and the two can be tested, transported and stored independently; the communication terminal and antenna are combined into an independent module outside the pressure-resistant cabin of the underwater vehicle, which is conducive to the combination and modular design of the underwater vehicle.
