Description

Technical Field

These communication technologies mainly rely on radio signals for data transmission, but when radio signals are traveling at sea, they are often interfered by seawater, atmosphere, electromagnetic and other factors or have insufficient coverage, resulting in reduced communication quality and efficiency.

[0003] LiFi technology is a new wireless transmission technology that uses visible light spectrum for data transmission. It uses electrical signals to control the brightness of LED by implanting a tiny chip on the LED lamp to transmit information. Compared with radio communication technology, LiFi technology has the advantages of large bandwidth, high speed, strong security and no interference. It is suitable for communication occasions that require high speed, high density and high security.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0030] The present invention provides a technical solution: a ship communication device based on lifi technology, comprising a communication device 10 for ship communication, comprising a base 1, the upper surface of the base 1 is fixedly connected with a vertical pole 2, the top of the vertical pole 2 is fixedly connected with a U-shaped frame 3, the top of the U-shaped frame 3 is fixedly connected with two symmetrical rings 4, the inner walls of the two rings 4 are fixedly connected with a cross rod 5, the remaining two ends of the cross rod 5 are both limitedly connected with a ring 2 6, a rectangular frame 61 is provided above the vertical pole 2, the top of the rectangular frame 61 is fixedly connected with an n-shaped frame 7, the upper surface of the n-shaped frame 7 is fixedly connected with a connecting column 8, the top of the connecting column 8 is fixedly connected with a shell 9, and the upper surface of the shell 9 is fixedly connected to the bottom of the communication device 10.

[0031] Working principle of embodiment 1:

[0032] refer to Figure 1 , the communication device 10 includes an LED transmitter: using an LED lamp as a signal transmission source, and transmitting data by modulating the brightness of the LED;

[0033] Includes a photodetector: receives the light signal from the LED and converts it into an electrical signal;

[0034] Including signal processor: demodulate, decode, amplify and process the received electrical signal to restore the original data information;

[0035] Including signal modulator: encode, modulate and process the data information to be sent to generate an electrical signal suitable for LED emission;

[0036] Includes power manager: provides stable power supply for LED emitters and other modules;

[0037] The connection and coordination between the above modules mainly rely on circuit boards and software control. There are various interfaces and chips on the circuit board to realize signal transmission and conversion between modules. Software control is mainly responsible for realizing synchronization and protocols between modules, as well as handling some abnormal situations. For example, when the brightness of the LED transmitter changes, the software control needs to adjust the parameters of the signal processor to ensure the quality of the received signal;

[0038] The equipment is installed and fixed on the ship as a whole through the base 1, which can be fixed by bolts. The U-shaped frame 3 is supported by the vertical pole 1 2, and the ring 1 4 is supported by the U-shaped frame 3. The cross rod 5 is provided with rotation support in the direction indicated by the arrow A through the ring 1 4;

[0039] As the cross rod 5 rotates in the direction of arrow A, the communication device 10 as a whole is stably rotated in the direction of arrow A through the transmission of the rectangular frame 61, the n-shaped frame 7, the connecting column 8 and the housing 9;

[0040] Since LiFi technology uses visible light for data transmission, there needs to be a line-of-sight link between the transmitter and receiver of the communication device, that is, the light cannot be blocked or deviated. If the transmitter or receiver turns or moves, it may cause link interruption or signal attenuation, affecting the communication quality;

[0041] The two ends of the cross bar 5 provide support for the movement of the ring 2 6 and the rectangular frame 61 in the direction of arrow B, and the communication device 10 can be stably rotated in the direction of arrow B through the transmission of the n-shaped frame 7, the connecting column 8 and the shell 9. At this point, the independent rotation adjustment of the communication device 10 on arrow A and arrow B is completed, which can not only meet the needs of complex and changeable steering adjustment in the actual use process to meet the establishment and optimization of the link; further ensure the relative position and angle between the transmitter and the receiver, adjust the direction and shape of the light beam in real time, and maintain the alignment and stability of the link. In actual use, multiple transmitters and receivers can also be used to form a multi-input multi-output system, and use spatial diversity or spatial multiplexing to improve the reliability and capacity of the link.

[0042] Furthermore, the base 1 is also provided with a power device for driving the steering adjustment of the rectangular frame 61, and the power device includes two universal ball seats 11 fixed on the upper surface of the base 1, the inner wall of the universal ball seat 11 is movably connected with a universal ball 12, the top of the universal ball 12 is fixedly connected with a sleeve 13, the inner wall of the sleeve 13 is axially slidably connected with a telescopic rod 14 pushed and moved by a power mechanism, the top of the telescopic rod 14 is fixedly connected with a universal ball 15, the outer contour of the universal ball 15 is covered with a universal ball seat 16, the surface of the universal ball seat 16 penetrates and is fixedly connected with a connecting frame 17 fixed on the outer contour surface of the rectangular frame 61, and the two connecting frames 17 are located on two adjacent sides of the rectangular frame 61;

[0043] refer to Figure 1 The power mechanism is an electric push rod, which is placed in the sleeve 13 and protected by the sleeve 13, thereby extending the service life in the water environment; in actual use, when the communication device 10 needs to rotate in the direction of arrow A, by driving one of the telescopic rods 14 to move axially in the sleeve 13, the universal ball 15, the universal ball seat 16, the universal ball seat 16 and the connecting frame 17 are driven to promote the rotation of the cross rod 5 as a whole in the ring 1 4, thereby achieving the above effect;

[0044] When the communication device 10 needs to be rotated in the direction of arrow B, the sleeve 13 in the other telescopic rod 14 needs to be axially moved to cause the rectangular frame 61 and the ring 2 6 to rotate on the cross rod 5 in the direction indicated by arrow B.

[0045] The relative movement of the two telescopic rods 14 and the sleeve 13 to realize the rotation of the rectangular frame 61, the second ring 6, the n-shaped frame 7, the connecting column 8 and the housing 9 is relatively clear and easy to understand, and the internal structure is the same, so the number setting is unified;

[0046] Embodiment 2, based on embodiment 1, further comprises:

[0047] A support ring 18 is disposed above the housing 9 , and high-power lasers 19 are distributed in a circular pattern on the upper surface of the support ring 18 .

[0048] The high-power laser 19 is fixedly supported by the support ring 18, and the laser is emitted through the support ring 18 to emit a high-energy beam to heat the water droplets in the water mist. The laser scans or irradiates along the target direction to heat and evaporate the water droplets in the water mist, forming a low-concentration or water mist-free channel. In the extreme foggy environment on the water surface, a stable working environment is provided for the optical path transmission of the communication device 10 to ensure the communication quality;

[0049] Furthermore, the support ring 18 is also integrated with an alignment laser, a machine vision camera, a control system and an optical communication transceiver;

[0050] By aiming laser: used to emit a low-power visible beam as a reference signal for aiming at the target;

[0051] Machine vision camera: used to receive the visible light beam emitted by the alignment laser, detect its position and angle, and feed back to the control system;

[0052] Control system: used to control the steering and adjustment of high-power continuous laser or pulse laser and alignment laser according to the feedback signal of the machine vision camera, so as to realize the alignment and calibration of the optical path;

[0053] Optical communication transceiver: used for data transmission and reception within the formed channel;

[0054] By using the above-mentioned devices in coordination, the laser light emitted by the aiming laser can be used for calibration and real-time monitoring of the receiving and transmitting links of the communication device 10 .

[0055] Embodiment three, the upper surface of the base 1 is provided with a transmission device for driving the high-power laser 19 and the support ring 18 to rotate as a whole, the transmission device includes a side upright pole 20 fixed on the upper surface of the base 1, a pull rope 21 is fixedly connected to the outer contour of the side upright pole 20, a transmission ring 22 is fixedly connected to the arc contour of the support ring 18, a connecting ring 23 is axially clamped on the transmission ring 22, and an annular through groove for the connecting ring 23 to rotate on a fixed axis is opened on the upper surface of the shell 9, and the end of the pull rope 21 away from the side upright pole 20 passes through the shell 9 and is wound and stored on the arc contour of the connecting ring 23.

[0056] Working principle of embodiment 3:

[0057] refer to Figure 1 , as can be seen from the foregoing content, the communication device 10 will be synchronously adjusted along with the housing 9 to meet the link angle calibration operation;

[0058] Once the housing 9 is Figure 1 The vertical state in the housing 9 deflects, which releases the rope 21 wrapped around the outer contour of the connecting ring 23, thereby causing the connecting ring 23 to rotate on a fixed axis on the housing 9, thereby driving the synchronous rotation of the support ring 18 and the high-power laser 19, thereby forming a complete tubular channel, which can more efficiently eliminate the moisture in the target path; the high-power laser 19 can be used in extreme foggy environments to provide a stable working environment for the optical path transmission of the communication device 10 to ensure the communication quality. For example, when encountering dense fog at sea, radio communications between ships and between ships and shores may be severely interfered with or interrupted, while visible light communication can use the laser emitted by the high-power laser 19 to heat the water droplets in the water mist, forming a low-concentration or water-free channel, and transmitting and receiving data in the channel, thereby realizing high-speed, high-density, and high-security ship communications.

[0059] And when the rotation adjustment of the shell 9 is completed, the rotation of the connecting ring 23 stops, but the transmission ring 22 still has inertia in the connecting ring 23, so that the transmission ring 22 will continue to rotate with the support ring 18 and the high-power laser 19 to continue to form a tubular light path; that is, after the steering adjustment is completed, the support ring 18 and the high-power laser 19 continue to rotate, heating the water droplets in the water mist for the new path, and accelerating the formation of the target channel.

[0060] Furthermore, an inner support ring 24 is fixedly connected to the inner wall of the connecting ring 23 , a torsion spring 25 is fixedly connected to the bottom of the inner support ring 24 , and the bottom of the torsion spring 25 is fixedly connected to the upper surface of the shell 9 .

[0061] As can be seen from the previous content, when the shell 9 is deflected, the connecting ring 23 will rotate inside the shell 9. This rotation needs to overcome the elastic force of the torsion spring 25 to be released. When the shell 9 is reset and rotated, the elastic force of the torsion spring 25 is released, allowing the connecting ring 23 to reset and rotate, and the pull rope 21 is rewound and stored to prepare for the next use.

[0062] Embodiment 4, based on embodiment 3, further comprises:

[0063] A cam ring 26 is installed on the arc-shaped outer contour of the connecting ring 23, and the outer contour of the cam ring 26 is rotatably connected to an external connecting ring 27 at the upper limit position, and a transmission handle 28 is fixedly connected to the side of the external connecting ring 27 away from the side upright 20, and a push rod 29 is penetrated through the transmission handle 28 and axially slidably connected, and one end of the push rod 29 is fixedly connected to a rotating arm 30 that is supported and rotates around a fixed axis, and an elastic wiping handle 31 that rotates coaxially with the rotating arm 30 is provided at the rear of the rotating arm 30, and the top of the elastic wiping handle 31 extends to the top of the communication device 10 and is movably connected to the top of the communication device 10.

[0064] Working principle of the fourth embodiment:

[0065] refer to Figure 1 , the rotating arm 30 is supported to perform stable fixed-axis rotation, and the push rod 29 on the rotating arm 30 can also perform stable rotation. After the push rod 29 passes through the transmission handle 28, the movement trajectory of the transmission handle 28 and the external connecting ring 27 is limited. When the connecting ring 23 drives the cam ring 26 to rotate, the outer contour of the cam ring 26 will guide the external connecting ring 27 to move. One direction of movement is the axial movement of the transmission handle 28 on the push rod 29 driven by the external connecting ring 27, and the other direction is the radial horizontal movement of the transmission handle 28 driven by the external connecting ring 27. The radial direction is relative to the push rod 29.

[0066] By pushing the push rod 29 to move radially, the fixed-axis rotation of the rotating arm 30 is achieved, and then the synchronous swing coaxially with the rotating arm 30 is achieved. When the swing is in a reciprocating form, the wiping operation on the end of the communication device 10 is achieved, further improving the efficiency during the link calibration process.

[0067] Furthermore, an extension seat 32 is fixedly connected to the arc-shaped contour of the shell 9, and a fixed shaft 33 is penetrated and fixedly connected to the extension seat 32. The two ends of the fixed shaft 33 are fixedly connected to the opposite surfaces of the rotating arm 30 and the elastic wiping handle 31. A torsion spring 34 is sleeved on the arc-shaped contour of the extension seat 32, and the two ends of the torsion spring 34 are fixedly connected to the opposite surfaces of the extension seat 32 and the elastic wiping handle 31.

[0068] The extension seat 32 and the fixed shaft 33 are provided to support the rotation of the rotating arm 30 and the elastic wiping handle 31. The torsion spring 2 34 is provided to horizontally reset the elastic wiping handle 31 after the communication device 10 stops steering adjustment under the elastic force of the torsion spring 2 34, thereby reducing and avoiding interference with the light emitted by the high-power laser 19. The push rod 29 and the transmission handle 28, as well as the cam ring 26 and the external connecting ring 27 are provided with a structural movement clearance for cooperating with the torsion spring 2 34 to release the elastic force on the torsion spring 2 34. In actual use, the reset operation can also be performed by manual control. The elastic wiping handle 31 is provided with bristles for flexibly wiping the communication device 10.

[0069] In order to facilitate understanding of the internal structure, the transmission ring 22, the connecting ring 23 and the inner support ring are all half-sectioned.

[0070] Working principle: The ship communication device based on lifi technology, the communication device 10 includes an LED transmitter: LED lamp is used as a signal transmission source, and data is transmitted by modulating the brightness of the LED. The device is installed and fixed on the ship as a whole through the base 1, which can be fixed by bolts. The U-shaped frame 3 is supported by the vertical pole 2, and the ring 4 is supported by the U-shaped frame 3. The cross rod 5 is provided with rotation support in the direction indicated by the arrow A through the ring 4; along with the rotation of the cross rod 5 in the direction of arrow A, the communication device 10 is driven by the rectangular frame 61, the n-shaped frame 7, the connecting column 8 and the shell 9 to realize the stable rotation of the whole communication device 10 in the direction of arrow A; because lifi technology uses visible light for data transmission, there needs to be a line-of-sight link between the transmitter and the receiver of the communication device, that is, the light cannot be blocked or deviated. If the transmitter or receiver turns or moves, it may cause link interruption or signal attenuation, affecting the communication quality; the two ends of the cross rod 5 provide support for the movement of the ring 2 6 and the rectangular frame 61 in the direction of arrow B, and the communication device 10 can be stably rotated in the direction of arrow B through the transmission of the n-shaped frame 7, the connecting column 8 and the shell 9. At this point, the independent rotation adjustment of the communication device 10 on arrow A and arrow B is completed, which can meet the needs of complex and changeable steering adjustment in the actual use process to meet the establishment and optimization of the link; further ensure the relative position and angle between the transmitter and the receiver, adjust the direction and shape of the light beam in real time, and maintain the alignment and stability of the link. In actual use, multiple transmitters and receivers can also be used to form a multi-input multi-output system, and use spatial diversity or spatial multiplexing to improve the reliability and capacity of the link.
