Description

Technical Field

[0001] The present invention relates to the technical field of power control and power supply, and in particular to a method and system for controlling power supply of optical fiber communication. Background Art

[0002] The fiber-optic communication power supply control system originates from the rapid development of fiber-optic communication technology. With the advent of the information age, fiber-optic communication, as a mainstream technology for high-bandwidth and long-distance transmission, is widely used in communication networks, data centers and other fields. However, the stable operation of fiber-optic equipment requires extremely high power supply, especially for remote communication sites. Traditional power supply methods face maintenance difficulties and low efficiency. Therefore, the fiber-optic communication power supply control system came into being, aiming to provide more efficient and stable power guarantee for fiber-optic communication equipment; initially, basic power allocation was achieved through simple power management, and with the advancement of technology, intelligent monitoring, load balancing, fault warning and other functions were gradually added. In recent years, combined with technologies such as big data and cloud computing, the fiber-optic communication power supply control system has continued to develop, gradually realizing automated management, and improving the intelligence, reliability and energy utilization of the system.

[0003] Although the optical fiber communication power supply control system has the advantages of high efficiency and stability in practical applications, it still has some technical disadvantages, as follows:

[0004] 1. High risk of power outage: Fiber optic communication equipment is highly dependent on electricity. In long distances or remote areas, power lines are easily affected by natural disasters (such as lightning strikes and earthquakes) and cause interruptions. For example, when laying optical cables along the coast, typhoons may cause damage to power lines and affect communications.

[0005] 2. Insufficient energy consumption management: The existing system is difficult to achieve accurate energy consumption control when the load changes. Some areas may have excess power while others may be insufficient, resulting in energy waste or unstable equipment operation. For example, the redundant power supply modules of the optical fiber network in a large data center consume too much power.

[0006] 3. Lack of real-time fault warning: The existing system has a lag in fault monitoring, making it difficult to detect and handle problems in a timely manner. For example, when the power supply voltage is abnormal, the problem is often discovered only after the equipment is shut down, affecting the continuity of communication services. Summary of the invention

The specific contents are as follows:

[0041] When the fault coupling influence factor Efi≤the second fault coupling threshold R2, the first operating state is generated at this time; it means that there is no fault in the power supply path and there is no risk of environmental interference, the system runs smoothly, and the load distribution of the power supply path is balanced; no additional measures are required to maintain the current power distribution strategy and maintain normal power supply in each power supply area;

[0042] When the first fault coupling threshold R1 ≥ fault coupling influence factor Efi > second fault coupling threshold R2, the second operating state is generated at this time; indicating that there is a fault risk or environmental interference in the power supply path, but it does not cause a major threat to the overall power supply stability; at this time, dynamic optimization of power distribution is carried out to mitigate potential risks. The control strategies adopted include dynamic adjustment of power distribution and continuous monitoring and early warning;

[0043] When the fault coupling influence factor Efi> the first fault coupling threshold R1, the third operating state is generated at this time; it indicates that the power supply path has been affected by the fault or threatened by environmental interference, and at the same time caused power outage or equipment damage, and emergency measures must be taken immediately; the control strategies adopted include starting the backup power supply mode, emergency adjustment of power distribution, and issuing early warnings.
