Furthermore, existing terahertz communication systems suffer from deficiencies such as insufficient multi-service integration capabilities, weak network security, and high power consumption, making them unable to adapt to the future development needs of high-speed, highly reliable, and low-latency communication networks.

[0062] In summary, the working principles of the ultra-long-haul, low-latency terahertz optical fiber ring network base station and edge intelligent processing system provided in this embodiment are as follows:

[0063] (1) Principles of terahertz signal emission and transmission

[0064] The terahertz signal transmission and reception module uses a novel quantum cascade laser to generate stable terahertz waves, which are transmitted in a directional manner via a beamforming antenna array. A combination of QAM and PPM modulation is used to enhance signal interference resistance. Once the signal enters the fiber ring network transmission module, it is transmitted over ultra-long distances using low-attenuation specialty optical fibers doped with rare earth elements. Distributed fiber amplifiers noiselessly amplify the signal based on stimulated Raman scattering. The fiber ring network's intelligent scheduling nodes dynamically optimize transmission paths based on link status, ensuring low-loss, relay-free transmission.

[0065] (2) Edge Intelligent Processing and System Collaboration Principles

[0066] The edge intelligent processing module uses an acceleration unit integrated in a 7nm chip to locally process data carried by terahertz signals in real time. A local data cache and management unit enables efficient data reading and writing, and an intelligent decision-making and control unit automatically adjusts base station parameters based on deep learning algorithms. The terahertz and fiber optic conversion interface module enables efficient signal conversion between different media. A self-diagnosis and self-repair mechanism uses sensors to monitor module status in real time and automatically switches to backup resources in the event of a failure. Multi-service converged transmission uses QoS policies to provide differentiated protection. Standardized interfaces ensure interoperability among modules, and intelligent power management dynamically adjusts power based on load.

[0067] How to use

[0068] (1) System deployment and network construction

[0069] Special optical fibers doped with rare earth elements are laid in a ring topology, and distributed optical fiber amplifiers and optical fiber ring network intelligent scheduling nodes are deployed at intervals of 50km to form an optical fiber ring network transmission module.

[0070] Install terahertz signal transmission and reception modules at the ring network nodes, adjust the beamforming antenna array to point to the target coverage area, and connect the terahertz and fiber optic conversion interface module.

[0071] Deploy edge intelligent processing modules, complete communication protocol configuration with other modules through standardized interfaces, and access the power supply and cooling system.

[0072] (2) Business configuration and system operation

[0073] Set up multi-service QoS policies in the edge intelligent processing module, prioritize services such as high-definition video and IoT data, and configure key service latency guarantee parameters.

[0074] Start the system self-diagnosis program, detect the working status of each module through the built-in sensor, and complete the initial parameter configuration such as terahertz laser power and modulation mode.

[0075] When accessing business data streams, the system automatically optimizes the transmission path through intelligent scheduling nodes. The edge chip processes data in real time, and the intelligent decision-making unit dynamically adjusts the transmission power and working mode according to the network load to achieve multi-service converged transmission and low-latency processing.

[0076] (3) Maintenance and upgrade

[0077] The system self-diagnosis function generates status reports regularly and automatically triggers the self-repair mechanism when a fault is detected, switching to a backup module and recording a fault log.

[0078] Access new base station equipment or edge applications through standardized interfaces, update the deep learning algorithm model of the edge intelligent processing module, and achieve system function expansion and performance upgrade.

[0079] Workflow

[0080] (1) System initialization process

[0081] 1. Hardware self-test: After the system starts, the built-in sensor automatically detects the connection status, power supply status, and performance of key components of hardware devices such as the terahertz signal transmission and receiving module, optical fiber ring network transmission module, and edge intelligent processing module, and generates an initial hardware status report.

[0082] 2. Parameter configuration: Based on the preset network planning scheme, the transmission power and modulation mode of the terahertz quantum cascade laser are configured in the edge intelligent processing module, the link monitoring period and load balancing strategy of the optical fiber ring network intelligent scheduling node are set, the multi-service QoS priority parameters are divided, and the configuration information is synchronized to each related module.

[0083] 3. Network registration: The terahertz fiber ring network base station registers with the core network through a standardized interface, reports device identification, performance parameters and service capabilities, obtains network-allocated resource permissions and communication keys, and establishes a connection channel with the core network.

[0084] (2) Business data transmission process

[0085] 1. Data access and preprocessing: User service data (such as high-definition video streams and IoT sensor data) is connected to the terahertz signal transmission and reception module. Before being transmitted directionally by the beamforming antenna array, it is first encoded by the modulation unit using a combination of QAM and PPM modulation to improve data anti-interference capabilities and transmission efficiency.

[0086] 2. Ring Network Transmission and Scheduling: The modulated terahertz signal is converted into an optical signal via a terahertz-to-fiber conversion interface module and then enters a special fiber ring network doped with rare earth elements. The fiber ring network's intelligent scheduling nodes monitor the signal strength, bandwidth utilization, and other status of each link in real time. Based on a load balancing algorithm, they dynamically select the optimal transmission path. Distributed fiber amplifiers simultaneously provide noise-free amplification, ensuring data stability over ultra-long distances.

[0087] 3. Edge Processing and Distribution: After data is transmitted to the target base station's edge intelligent processing module, it is temporarily stored in the local data cache and management unit. The acceleration unit, combined with deep learning algorithms, performs real-time data analysis and processing (such as video compression and IoT data filtering). Based on the service type and QoS policy, the processed data is transmitted back to the user terminal via the terahertz signal transmission and reception module, or forwarded to other nodes via the optical fiber ring network.

[0088] (3) Dynamic optimization and adaptive adjustment process

[0089] 1. Network status monitoring: The optical fiber ring network intelligent scheduling nodes and edge intelligent processing modules continuously monitor network link status, business load changes, and user demand fluctuations, collect key indicators such as signal attenuation rate, data throughput, and latency, and form a real-time network status database.

[0090] 2. Intelligent Decision-Making and Parameter Adjustment: The intelligent decision-making and control unit analyzes and predicts monitoring data based on a deep learning model. When link congestion is detected, the system automatically adjusts the data transmission path. If traffic load surges, the system dynamically increases the terahertz laser transmit power or switches to a higher-order modulation method. Furthermore, the system optimizes the pointing angle of the beamforming antenna array based on environmental changes to ensure signal transmission quality.

[0091] (IV) Fault response and repair process

[0092] 1. Fault detection: The system self-diagnosis module uses built-in sensors to scan the operating status of each module in real time. Once a hardware fault (such as abnormal laser power or fiber link interruption) or software anomaly (such as algorithm operation error or communication protocol interruption) is detected, the fault location is immediately marked and a fault code is generated.

[0093] 2. Emergency Response: Fault information triggers a self-repair mechanism. The system prioritizes maintaining service operations by switching to backup modules (such as backup fiber links and redundant computing units). The system also uploads the fault code and detailed logs to the maintenance center. If backup resources are insufficient, non-critical services are automatically prioritized to ensure core business continuity.

[0094] 3. Repair and recovery: After maintenance personnel repair the fault remotely or on-site based on the fault log, the system will re-perform self-tests and parameter calibration. After confirming that the fault has been eliminated, full business operations will be restored and the fault handling record will be updated to provide data support for subsequent optimization.

[0095] In summary, this system, by combining terahertz quantum cascade lasers with low-attenuation specialty optical fibers, overcomes the distance limitations of traditional terahertz communication transmission, enabling ultra-long-distance, relay-free transmission. The local real-time computing capabilities of the edge intelligent processing module eliminate data backhaul latency, meeting the needs of low-latency services. Beamforming and novel modulation schemes enhance signal interference resistance, while distributed amplification and intelligent scheduling ensure transmission reliability. Multi-service QoS strategies provide differentiated protection. Self-diagnosis and repair mechanisms reduce maintenance costs, standardized interfaces enhance scalability, and intelligent power management achieves green energy conservation. Overall, this system builds a highly reliable, low-latency, and scalable next-generation terahertz communication network architecture.

[0096] The above are only preferred embodiments of the present invention and do not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
