High-speed and reliable communication technologies play an increasingly important role in various fields. From global data transmission to military communication, from smart cities to the construction of the Internet of Things, the stability and transmission efficiency of communication technologies have become the core needs of various industries. Especially laser communication, with its extremely high transmission speed, large-capacity transmission ability, and excellent confidentiality, has gradually become an important development direction of communication technology. The multi-node laser communication networking system has become a research hotspot in the communication field due to its outstanding advantages such as high speed, large capacity, and high confidentiality. When traditional multi-node laser communication networking systems achieve communication between nodes, they often face problems such as tight channel resources, serious signal interference, and low communication efficiency.

[0003] Traditional laser communication systems usually adopt a point-to-point communication method, and each communication node needs to be independently configured with a transceiver terminal. This architecture leads to an increase in the complexity of the system and a sharp increase in energy consumption. Especially in scenarios with a large number of nodes, each node requires independent optical transmitting and receiving devices, control systems, and power supplies. This not only increases the cost of hardware and the difficulty of maintenance, but also requires continuous power supply for each node, further increasing the energy consumption of the system.

[0004] To address the problems faced by traditional laser communication systems in multi-node networking, such as complex nodes, high energy consumption, low communication efficiency, and high dependence on precise alignment, the present invention proposes a multi-node laser communication networking system based on dynamic time-division control of a self-rotating mirror. This system uses a self-rotating mirror as a transmission node and combines a time-division communication mechanism to break through the limitations of traditional one-to-one laser communication systems. It can effectively simplify the networking process, reduce energy consumption, and simultaneously reduce the dependence on precise alignment, improving the reliability and efficiency of communication. The time-division laser communication system of the present invention mainly includes the following technical modules: (1) Laser signal processing module: responsible for the transmission, reception, and signal processing of laser signals to achieve efficient and reliable transmission of laser signals; (2) Control and scheduling module: serving as the control center of the entire system, responsible for the allocation of communication requirements and the generation of time-division communication instructions; (3) Communication control strategy: responsible for dynamically allocating time slots according to requirements to ensure stable signal transmission and ensure communication within the corresponding time period to avoid signal interference; (4) Dynamic adjustment module: adjusts the angle of the rotating self-rotating mirror to achieve dynamic adjustment of laser signals. The time-division communication mechanism is used to ensure that the self-rotating mirror module rotates to the target optical terminal in different window times, improving the utilization rate of resources; (5) Optical adjustment module: responsible for precisely controlling the pan-tilt to achieve adjustment of the angles and positions of the self-rotating mirror and the optical terminal, ensuring accurate transmission and reception of laser signals, and enhancing the adjustability and stability of the system; (6) Redundancy and health monitoring module: responsible for monitoring the health status of equipment and redundant backup to ensure the stable operation of the system and ensure the continuity and stability of the system.

[0011] Furthermore, the main control computer 6 communicates with the ring network optical terminals (1, 2, 3), the pan-tilt 4, and the self-rotating mirror 5 through optical fibers. The main control computer is responsible for dynamically allocating communication time slots according to the communication requirements and priorities of each node and generating control instructions to guide the system to communicate at different times, avoiding signal conflicts. At the same time, it monitors the communication quality in real time and dynamically adjusts the communication parameters according to the feedback information to ensure communication stability and reliability.

[0012] The present invention provides a multi-node laser communication networking system based on dynamic time-sharing control of a self-rotating mirror. The solution includes the following steps:

The main control computer 6 establishes a communication connection with the ring network optical terminals (1, 2, 3) and the self-rotating mirror 5, configures the transmission power, wavelength, and modulation mode of the ring network optical terminals (1, 2, 3), and assigns a unique node address to ensure the accuracy of data transmission. At the same time, the pan-tilt 4 is initialized so that it can accurately adjust the angle according to the instruction to ensure efficient transmission of the laser signal.

[0015] S3. The main control computer 6 controls the self-rotating optical mirror 5 to the initial position for angle calibration. According to the current communication requirements, the main control computer 6 dynamically allocates communication resources, calculates and sets the rotation plan of the self-rotating optical mirror 5 to match the communication requirements of each optical terminal.

[0016] S4. The master computer 6 controls the rotation of the pan-tilt 4 according to the allocated communication resources, adjusts the angle and speed of the self-rotating optical mirror 5 to ensure that the laser signal is accurately reflected to the target optical terminal. During this period, the master computer monitors the communication time slots in real time to ensure that there is no communication conflict between each optical terminal;

[0017] S5. The target optical terminal receives and processes the laser signal and extracts the valid information. The master computer 6 monitors the communication quality in real time. If signal problems are found, adjustments and optimizations are carried out to ensure stable communication until completion;

[0018] S6. After the communication is completed, the master computer 6 sends an end signal to all optical terminals and records the performance data during the communication process.

By dividing the time slots and distinguishing the communication requirements priorities of each optical terminal, it ensures that each optical terminal conducts efficient and conflict-free communication within a predetermined time period.

[0020] As the core control unit of the present invention, the master computer of the present invention needs to be equipped with a high-performance processor that can execute complex communication requirement analysis and scheduling algorithms in real time. This processor supports real-time data processing and system monitoring to ensure efficient and stable communication among multiple optical terminals.

[0021] The beneficial effects of the present invention are as follows:

[0022] (1) Aiming at the problems of difficult alignment of laser signals and low transmission efficiency in traditional laser communication systems, the precise layout of the ring network optical terminals and the dynamic adjustment of the self-rotating optical mirror are adopted to achieve fast alignment and efficient communication between nodes. By dividing the time slots through the communication control strategy and distinguishing the priorities of communication requirements, it ensures efficient and conflict-free communication between optical terminals, further reducing the system complexity and improving the link stability.

[0023] (2) Through the ingenious layout of the ring network optical terminals and the self-rotating mirror forming an equilateral triangle, combined with the communication control strategy, the communication of each node is allocated to an independent time window, avoiding signal conflicts between nodes, ensuring accurate signal transmission, reducing the dependence on real-time alignment at the same time, and improving the system communication efficiency and resource utilization rate.

[0025] Figure 2 It is a block diagram of the composition of a multi-node laser communication networking system model based on dynamic time-sharing control of a self-rotating mirror; Detailed implementation mode

[0026] To make the objectives, features, and advantages of the present invention clearer and easier to understand, the following elaborates on the technical solutions of the present invention in detail and clearly in conjunction with the accompanying drawings in the embodiments of the present invention. It should be clear that the implementation of the present invention is not limited to the following listed embodiments, and specific implementation strategies can be determined according to the technical solutions of the present invention and specific situations in actual applications. For the purpose of avoiding confusion with the core content of the present invention, some well-known methods, processes, procedures, components, and circuits are not described in detail herein;

[0027] The multi-node laser communication networking system model based on dynamic time-sharing control of a self-rotating mirror provided in this embodiment is as Figure 1 shown, and includes ring network optical terminals (1, 2, 3), a pan-tilt 4, a self-rotating optical mirror surface 5, and a main control computer 6; among them, the three fixedly deployed ring network optical terminals (1, 2, 3) are arranged in an equilateral triangle layout and are opposite to the self-rotating optical mirror surface 5, symmetrically distributed at 120 degrees. The main control computer 5 is communicatively connected to the ring network optical terminals (1, 2, 3), the pan-tilt 4, and the self-rotating optical mirror surface 5 through optical fibers. The ring network optical terminals (1, 2, 3) and the self-rotating mirror surface 5 are connected to the pan-tilt 4 by mechanical connection means.

[0028] Each of the ring network optical terminals (1, 2, 3) is equipped with a high-performance laser transmitter and a sensitive photodetector. The laser transmitter uses a CW laser, with a wavelength range of 1550 nm, a modulation method of NRZ, and an output power that can be dynamically adjusted to meet the requirements of different communication distances and signal qualities. The high-sensitivity photodetector can use a PIN photodiode, support a light reception sensitivity of -28 dBm to 0 dBm, and is built-in with an automatic gain control (AGC) module to cope with the attenuation fluctuations of the optical fiber link and ensure the stability of the received signal quality. In addition, a signal processing unit should be integrated inside each ring network optical terminal. This unit includes an integrated GPS-tamed clock, an LMS adaptive equalizer, and a Reed-Solomon FEC encoder. The GPS-tamed clock can ensure the clock synchronization of each optical terminal, ensure the accuracy of the time stamps of each node in ring network communication, and achieve efficient and coordinated signal transmission and reception. The LMS adaptive equalizer can dynamically optimize the signal quality, and the FEC encoder is used to correct the error codes in communication to ensure that the signal is received and sent at the correct time point.

[0029] The pan-tilt 4 is equipped with a high-precision positioning system, adopts a two-axis servo motor drive system (horizontal axis and pitch axis), and is equipped with a planetary gear reduction mechanism (reduction ratio 1:1000) and a 17-bit high-precision optical encoder, achieving an azimuth adjustment accuracy of ≤0.01° and a repeat positioning error of ≤5 arcseconds. The movement of the pan-tilt 4 converts the rotational movement of the motor into the linear displacement of the pan-tilt 4 through a harmonic reducer and a ball screw, thereby precisely controlling the positions of the optical terminal and the self-rotating optical mirror 5. This design supports micron-level position correction of the optical terminal and the self-rotating mirror to ensure the precise transmission of laser signals. The main control computer 6 generates drive instructions based on the PID (Proportional-Integral-Differential) control algorithm, and dynamically adjusts the movement trajectory of the pan-tilt 4 through signal strength feedback and the position data of the reflected light spot of the self-rotating mirror. During communication, the pan-tilt 4 can accurately adjust the angles and positions of the ring network optical terminals (1, 2, 3) and the self-rotating optical mirror 5 carried thereon according to the instructions of the main control computer 6 to ensure the efficient alignment and transmission of laser signals.

[0030] The self-rotating optical mirror 5 is located at the center of the optical terminals forming an equilateral triangle layout, and realizes efficient and accurate signal transmission between different optical terminals by precisely controlling the reflection direction of the laser signal. The self-rotating optical mirror 5 can accurately rotate through the servo motor in the pan-tilt 4 after receiving the instructions of the main control computer 6 to ensure the stable transmission of the laser signal along the predetermined path. To ensure the accuracy of the rotation process, the encoder real-time monitors the rotation angle of the mirror and feeds the angle data back to the control system for transmission to the main control computer 6 to support the real-time scheduling and optimization of the system. The self-rotating optical mirror 5 not only receives instructions from the main control computer 6 but also feeds back its own status information to the main control computer 6. To ensure the stable operation of the laser communication system, the main control computer 6 dynamically adjusts the angle, speed, and signal transmission path of the self-rotating optical mirror 5 based on real-time status feedback and communication requirements. This enables the entire laser communication system to perform efficient and conflict-free signal transmission between different optical terminals, improving the stability, reliability, and real-time performance of the system.

[0031] The master computer 6 in this system is responsible for dynamically allocating communication resources according to communication requirements, ensuring that each optical terminal unit obtains the required laser communication service within an appropriate time period. Specifically, the master computer 6 collects the demand information of each optical terminal unit in real time through the communication interface with each optical terminal unit, including communication time, target optical terminal unit, required bandwidth, and other key parameters. Then, the master computer 6 will perform intelligent resource scheduling and allocation according to the current system status and resource availability to ensure that the communication requirements of each optical terminal unit are preferentially met. In addition, the master computer 6 is responsible for implementing communication control strategies to avoid signal interference and conflicts. Through precise time synchronization and scheduling algorithms, the master computer 6 assigns a pending communication period to each optical terminal unit and transmits these time periods and related information to the self-rotating optical mirror 5 and the corresponding optical terminal unit through an efficient communication protocol, thereby ensuring that the communication of each optical terminal unit is carried out within the predetermined time slots.

[0032] To ensure the accurate transmission and effective docking of laser signals, the master computer 6 calculates the rotation angle and rotation speed of the self-rotating mirror 5 and sends these instructions to the control system of the self-rotating mirror 5 to ensure that the laser signal can be accurately transmitted to the target optical terminal unit. At the same time, the master computer will send communication start and end instructions to each relevant optical terminal unit to ensure the orderly progress of the entire communication process.

[0033] The master computer 6 also integrates a real-time monitoring module, which is responsible for collecting the operation data of each communication component and performing real-time analysis and processing. By continuously monitoring the data of signal quality and equipment status, once an anomaly or potential fault is detected, the master computer 6 can quickly take corresponding measures to ensure the stable operation of the system and minimize the occurrence of communication interruptions or quality problems.

[0034] The present invention provides a multi-node laser communication networking system based on dynamic time-sharing control of a self-rotating mirror. The solution includes the following steps:

[0035] S1. The three fixedly deployed ring network optical terminal units (1, 2, 3) are arranged in an equilateral triangle layout, and the position of each optical terminal unit is opposite to the self-rotating optical mirror 5, forming a 120-degree symmetric distribution. By precisely aligning during the system installation process, it is ensured that each optical terminal unit can communicate with other optical terminal units through the laser signal reflected by the self-rotating mirror 5. This layout not only improves the signal transmission efficiency of the system but also ensures the accurate alignment and efficient transmission of the laser signal;

[0036] S2. The main control computer 6 establishes communication connections with the ring network optical transceivers (1, 2, 3) and the self-rotating mirror 5, configures the transmission power, wavelength, and modulation mode of the ring network optical transceivers (1, 2, 3), and assigns a unique node address to each optical transceiver to ensure the accuracy of data transmission. At the same time, it is necessary to initialize the pan-tilt 4 to ensure that it can accurately adjust the angle according to the instructions. The pan-tilt 4 is driven by a two-axis servo motor system and can adjust the angle and position according to the instructions of the main control computer 6 to ensure that the self-rotating optical mirror 5 can perform accurate angle adjustment during actual operation, ensuring the accurate transmission and reception of laser signals;

[0037] S3. The main control computer 6 sets the initial position and basic parameters of the self-rotating optical mirror 5, including the rotation range and rotation speed, performs angle calibration. According to the current communication requirements, the main control computer 6 dynamically allocates communication resources, calculates and sets the rotation plan of the self-rotating optical mirror 5 to match the communication requirements of each optical transceiver;

[0038] S4. During the predetermined communication period, the main control computer 6 controls the rotation of the pan-tilt 4 according to the allocated communication resources, adjusts the angle and rotation speed of the self-rotating optical mirror 5 to ensure that the laser signal is accurately reflected and transmitted to the target optical transceiver. During this process, the main control computer 6 monitors the communication time slots of each optical transceiver in real time, avoids communication conflicts between optical transceivers, and ensures that each optical transceiver communicates without interference according to the priority and predetermined time;

[0039] S5. After the target optical transceiver receives the laser signal, it demodulates and processes the signal, extracts the effective information and feeds it back to the main control computer. The main control computer 6 monitors the signal quality in real time, including communication parameters such as signal strength and bit error rate. If a signal quality problem is detected, the main control computer automatically adjusts the communication parameters for optimization to ensure stable and reliable communication until the communication task is completed;

[0040] S6. After the communication ends, the main control computer 6 sends an end signal to all optical transceivers participating in the communication and closes the communication channel. The main control computer 6 will record various performance data during the communication process for subsequent system optimization and fault diagnosis to ensure that the entire system can operate continuously and stably under different conditions.

[0041] As a key component of the present invention, the present invention also includes a communication control strategy. All optical transceivers and self-rotating mirrors achieve precise time synchronization through GPS to ensure consistent clocks among all nodes. This precise time synchronization provides a fundamental guarantee for subsequent communication time slot allocation and signal transmission. The system dynamically allocates communication time slots according to the communication requirements, priorities, and network load conditions of the optical transceivers. This dynamic allocation mechanism can be flexibly adjusted according to the actual situation to improve the utilization efficiency of communication resources. The master control computer sends instructions to the servo motor in the pan-tilt head to control the rotation speed and direction of the self-rotating mirror, ensuring that the laser signal can be accurately sent to the target optical transceiver within the predetermined time. The target optical transceiver processes the received signal using advanced signal processing techniques and optimizes the signal quality using adaptive equalization techniques to ensure stable signal transmission. The advanced signal processing and optimization techniques can effectively cope with various interferences and improve the reliability of communication.

[0042] Meanwhile, the master control computer dynamically adjusts the communication strategy and system parameters according to the feedback information by real-time monitoring of communication quality, including parameters such as signal strength, bit error rate, and delay, to optimize the communication process. To further ensure the reliability of the system, a self-healing ability is adopted, which can automatically reallocate time slots and adjust the coordinated control of the optical transceiver and the self-rotating mirror when the link is interrupted or the communication quality deteriorates. In addition, the system supports dynamically adjusting communication parameters according to external environmental conditions (such as weather changes, light interference, etc.) to ensure a stable communication link.

[0043] As a key component of the present invention, the master control computer of the present invention needs to be equipped with a high-performance processor to support complex communication requirement analysis, scheduling algorithms, and real-time data processing and monitoring to ensure the high efficiency and stability of the system. In addition, the master control computer also needs to have a large-capacity memory and storage device, a high-speed communication interface to ensure high-speed and reliable data exchange between the optical transceiver and the self-rotating mirror, adopt a real-time operating system for efficient execution of the system, and at the same time adopt dual-power redundancy and data backup to provide a solid foundation guarantee for the stable operation of the system to cope with risk measures. A multi-node laser communication networking system model based on dynamic time-sharing control of a self-rotating mirror of the present invention includes: a laser signal processing module, a control and scheduling module, a communication control strategy, a dynamic adjustment module, an optical adjustment module, a redundancy and health monitoring module. The specific contents are as follows:

[0044] Through the collaborative work of multiple modules, this system ensures the efficient and stable transmission of laser signals. The laser signal processing module is responsible for signal emission, reception, and processing, adjusting the power and modulation mode of the laser transmitter to ensure signal quality. Meanwhile, the photodetector ensures accurate reception of signals through sensitivity adjustment. The control and scheduling module, as the core of the system, collects communication requirements and performs time slot allocation, and schedules in real time in combination with communication control strategies to ensure that each optical terminal communicates efficiently and without conflicts within the predetermined time slots. The communication control strategy improves the system stability and efficiency by dynamically adjusting communication resources, avoiding interference, and reasonably allocating resources. The dynamic adjustment module precisely adjusts the angle of the rotating mirror according to the time slot arrangement to ensure accurate signal transmission and improve the resource utilization rate of the system. The optical adjustment module achieves precise signal transmission by accurately controlling the positions of the pan-tilt and the optical terminal, enhancing the adjustability and stability of the system. The redundancy and health monitoring module is responsible for real-time monitoring of the device status, and can quickly take repair measures when abnormalities are found to ensure the continuity and reliability of the system.
