Description

Technical Field

[0001] This invention relates to the field of aviation connector technology, specifically to a high-speed, low-latency aviation connector communication device and a stable transmission method that can rotate 360 ​​degrees. Background Technology

[0002] Aviation connectors are indispensable components for connecting different devices, widely used in smart manufacturing, automation technology, aerospace, and other fields, primarily serving to transmit signals or supply power. Depending on the application area, operating frequency, and operating environment, aviation connectors have different structures and forms, such as fiber optic aviation connectors and cable aviation connectors, but they all share the common goal of ensuring reliable signal transmission. However, existing aviation connectors face major challenges, including ineffective rotation after being connected according to specific interface methods, inability to maintain efficient data transmission under strong vibration, and increased transmission latency. These difficulties significantly impact communication between different devices.

[0003] Space laser communication technology uses lasers as the information carrier and the atmosphere as the transmission medium to enable the transmission of voice, images, and data between different platforms in space. It boasts advantages such as high transmission rates, large information capacity, no spectrum limitations, strong anti-interference capabilities, small terminal size, light weight, and low power consumption. In contrast, traditional radio frequency communication suffers from low data transmission rates, susceptibility to strong electromagnetic interference, and poor security. Therefore, leveraging its advantages, space laser communication technology is widely used in aerospace, defense, and other fields. For example, SpaceX's Starlink project uses satellites equipped with space laser communication terminals to achieve laser communication between satellites in the same orbital plane and those in different orbital planes. This technology significantly reduces connection latency, and this project has promoted the application of space laser communication technology in future integrated space-air-ground networks. However, beam alignment between the transmitter and receiver is one of the main challenges facing space laser communication technology. Laser transmission in space is affected by atmospheric turbulence, platform vibration, and other factors, causing the laser spot at the receiver to shift, meaning the transmitter and receiver are not aligned in real time, thus reducing communication quality.

[0004] Existing aviation connectors cannot meet the application requirements of optical communication, especially in scenarios with high data transmission rates and low latency. The adverse effects of beam alignment problems are amplified, and the inability of aviation connectors to rotate effectively will cause wear and tear, ultimately failing to guarantee reliable signal transmission and, in severe cases, leading to problems such as disconnection.

[0005] In summary, existing aviation connectors cannot guarantee reliable signal transmission in high data transmission rate scenarios, and in severe cases, may lead to disconnection. Summary of the Invention

[0029] The optical receiving collimation system is connected to the beam splitter;

[0030] The beam splitter is connected to the detector.

[0031] The present invention discloses a stable transmission method for a high-speed, low-latency, 360-degree rotatable aviation plug communication device. This method is implemented using any of the aforementioned high-speed, low-latency, 360-degree rotatable aviation plug communication devices, specifically as follows:

[0032] When the aviation connector starts working, the light beam received through the optical fiber is transmitted to the optical reflection unit through the optical emission collimation system. The optical reflection unit reflects the light beam to the optical receiving collimation system. After the optical receiving collimation system collimates the light beam, it is coupled to the optical fiber of the beam splitter. The beam splitter splits the coupled light beam into two paths. One coupled light beam is transmitted to an external device through the optical fiber, and the other coupled light beam is transmitted to a detector. After the detector detects the spot energy information of the light beam on the beam splitter's optical fiber, it transmits the spot energy information to the feedback unit for processing through the feedback line.

[0033] The feedback unit includes the following steps:

[0034] Step S1: Establish the sliding mode control function for the optical reflection unit;

[0035] Step S2: Set the ideal motion trajectory of the optical reflection unit so that the reflected beam of the optical reflection unit is gradually focused on the center of the fiber end face on the beam splitter. The feedback unit obtains the position and energy information of the beam on the fiber end face of the beam splitter through the detector.

[0036] Step S3: The sliding mode controller generates a control signal to drive the optical reflection unit to adjust the beam reflection angle, so that the optical reflection unit can track the ideal motion trajectory and gradually make the beam converge to the center of the fiber end face. Then, it is calculated whether the coupling efficiency is at its maximum value and stable.

[0037] Step S4: The feedback unit continuously monitors the beam converging at the center of the optical fiber end face of the splitter through the detector to see if it is affected by external disturbances, which may cause a change in coupling efficiency. If the coupling efficiency decreases, step S3 is executed; otherwise, monitoring continues.

[0038] The control function of the sliding mode controller is as follows:

[0039]

[0040] y = x1;

[0041] Where x1 is the real-time output position of the light reflection unit, u is the sliding mode control quantity, d(t) is the bounded disturbance, and position error is the position error. This represents the ideal motion trajectory of the light-reflecting unit;

[0042] Sliding surface s = e2 + ce1, where the sliding control quantity

[0043] Where k1 and k2 are both greater than 0, the convergence rate of s depends on k1 and k2.

[0044] This invention solves the problem that existing aviation connectors cannot guarantee reliable signal transmission in high data transmission rate scenarios, and in severe cases, may lead to disconnection. Specific beneficial effects include:

[0094] This embodiment describes a stable transmission method based on the high-speed, low-latency, 360-degree rotatable aviation plug communication device of the present invention, combined with...

[0098] The light reflection unit 9 is used to change the transmission path of the light beam and reflect the light beam into the light receiving collimation system 11.1;

[0099] The optical receiving collimation system 11.1 is connected to the beam splitter 11.2, which splits the light beam into two paths. One path is connected to an external device, and the other path is connected to the detector 11.3.

[0100] The detector 11.3 is used to detect the energy change of the received light spot on the optical fiber of the beam splitter 11.2 and to determine whether the beam deviates from the center area of ​​the end face of the optical fiber of the beam splitter 11.2.

[0102] To better illustrate the stable transmission method of the high-speed, low-latency, 360-degree rotatable aviation plug communication device described in this application, the following embodiments are provided in detail:

[0103] In this embodiment, the optical emission collimation system 6 transmits the received light beam to the optical reflection unit 9, which then reflects the light beam to the optical receiving collimation system 11.1. After passing through the optical receiving collimation system, the light beam is transmitted to the beam splitter 11.2. The beam splitter 11.2 splits the light beam into two paths. One path is connected to an external device, and the other path is transmitted to the detector 11.3. The feedback unit 10 is connected to the detector 11.3. The feedback unit 10 outputs a control signal based on the change in the energy of the light spot detected by the detector 11.3 to drive the optical reflection unit 9 to process and adjust the angle of the reflected light beam until the light beam reflected by the optical reflection unit 9 is focused onto the center of the fiber end face of the beam splitter 11.2. This completes the establishment of a stable light beam transmission state for the entire system.

[0104] In this embodiment, the optical transmission collimation system 6 uses a single-mode fiber connection to receive optical signals from the outside, the feedback unit 10 uses a dual-core processing platform with FPGA+ARM structure to process the signals, and the detector 11.3 uses a PIN photodetector to measure the optical power output of the receiving splitter 11.2 fiber.

[0105] In this embodiment, the light reflection unit 9 adopts a piezoelectric driven MEMS galvanometer, which uses the inverse effect of piezoelectric material to drive the MEMS mirror to deflect and thus adjust the reflection angle of the light beam.

[0106] In this embodiment, as Figure 9 As shown, the processing procedure of feedback unit 10 is as follows:

[0107] (1) Establish the sliding mode control function for the light reflection unit 9;

[0108] (2) Set the ideal motion trajectory of the light reflection unit 9 so that the reflected beam of the light reflection unit 9 is gradually focused on the center of the fiber end face on the beam splitter. The feedback unit 10 obtains the position and energy information of the beam on the fiber end face of the beam splitter 11.2 through the detector.

[0109] (3) The control signal generated by the sliding mode controller drives the optical reflection unit 9 to adjust the beam reflection angle, so that the optical reflection unit 9 can track the ideal motion trajectory and gradually make the beam converge to the center of the fiber end face of the beam splitter 11.2.

[0110] (4) The feedback unit 10 continuously monitors the beam converging at the center of the fiber end face of the beam splitter 11.2 through the detector 11.3 to see if it is affected by external disturbances, which may cause a change in coupling efficiency. If the coupling efficiency decreases, the previous step is executed; if it remains unchanged, the monitoring continues.

[0111] The control function of the sliding mode controller is as follows:

[0112]

[0113] y = x1;

[0114] Where x1 is the real-time output position of the light reflection unit, u is the sliding mode control quantity, d(t) is the bounded disturbance, and position error is the position error. This represents the ideal motion trajectory of the light-reflecting unit;

[0115] Sliding surface s = e2 + ce1, where the sliding control quantity

[0116]

[0117] Where k1 and k2 are both greater than 0, the convergence rate of s depends on k1 and k2;

[0118] The sliding surface s is designed to allow the system to gradually enter an ideal stable state. After entering the sliding surface s, the system will move on the sliding surface s.
