Description

Technical Field

[0001] The present invention relates to the technical field of optical cable fiber splitting, and more particularly to an optical cable fiber splitting box for communication engineering. Background Art

[0002] With the rapid development of information technology, optical fiber communication networks, as a core component of modern communication infrastructure, carry the transmission requirements of massive amounts of data. As a key device in the fiber access network (such as FTTH, Fiber to the Home), the core function of the optical cable fiber splitting box is to split, distribute, and connect the optical fibers in the backbone optical cable to ensure efficient and reliable signal transmission to end users. However, with the popularization of technologies such as 5G, Internet of Things (IoT), and cloud computing, the dynamicity and burstiness of network traffic have increased significantly. The traditional design mode of optical cable fiber splitting boxes has gradually exposed technical bottlenecks, especially the insufficient response ability in dealing with real-time traffic fluctuations, which has become an important problem restricting the improvement of network service quality (QoS).

[0003] The current mainstream optical cable fiber splitting box technologies are mainly based on static configuration or semi-automatic management modes. Their typical working processes are as follows:

[0004] Manually preset time period strategy: Operators divide traffic levels in advance according to historical traffic data (such as weekdays and holidays, day and night), and configure fixed optical fiber switching strategies in the fiber splitting box. For example, increase the bandwidth allocation of specific optical fiber channels during the evening peak period.

[0005] Manual switching operation: When the actual traffic exceeds the preset threshold, it is necessary to rely on on-site or remote intervention by maintenance personnel to adjust the optical fiber connection path through physical switches or software instructions.

[0006] Simple threshold alarm mechanism: Some fiber splitting boxes integrate traffic monitoring modules, which can trigger alarms when the traffic reaches the preset threshold, but still require manual decision-making for subsequent operations.

[0007] Although such designs can meet basic requirements in scenarios with obvious periodic traffic patterns, their limitations are becoming more and more significant in high-dynamic network environments, specifically manifested as:

[0008] Serious response delay: The peak value of burst traffic (such as large-scale live broadcasts, instantaneous data backups) may last from several seconds to several minutes, while the average response time of manual intervention is usually above the minute level, resulting in network congestion, increased packet loss rate, and even service interruption. Measured data of a certain operator shows that in the scenario of burst video traffic, the switching delay of traditional fiber splitting boxes can reach 3 - 5 minutes, during which the network delay at the user end rises to more than 200 ms, seriously affecting the user experience.

[0009] Resource allocation rigidity: The preset strategy based on a fixed time period cannot adapt to the random fluctuations of traffic. For example, during the epidemic, the peak period of the surge in remote work traffic deviated severely from the traditionally preset "off-peak period", resulting in coexistence of insufficient or overloaded fiber optic utilization.

[0010] High operation and maintenance costs: Frequent manual intervention not only increases labor costs, but also increases the complexity of network operation and maintenance due to the risk of operation errors (such as optical path interruption caused by incorrect switching).

[0011] In summary, there is an urgent need for an intelligent, low-latency, and highly reliable optical cable fiber distribution box technology. Summary of the Invention

[0017] Furthermore, the calculation process of the real-time peak value of the output flow carried by the box body is as follows:

[0018] Step 1: Screen the features of the terminal data collected by the collection terminal to obtain the total number of users, the total number of single-user windows, the time window, the concurrency coefficient, and the redundancy coefficient;

[0019] Step 2: Single-user calculation: Import the data in Step 1 into the basic peak calculation model:

[0025] Step 6: Real-time flow comparison: Compare the real-time collected flow peak value with the theoretical real-time flow peak value, and output the comparison result to the matching end.

[0026] Furthermore, the comparison process in Step 6 is as follows:

[0042] Referring to Figures 1 to 6 , the present invention provides an optical cable fiber splitting box for communication engineering, including a box body assembly 1. On both sides of the inner side of the box body assembly 1, sliding positioning assemblies 3 are fixedly connected. Inside the fiber splitting assembly 2, a fiber splitting assembly 2 is installed. The box body assembly 1 includes a box body main body 101. On one side of the box body main body 101, a box body positioning groove 102 is opened. On both sides of the front surface of the box body positioning groove 102, circular grooves 103 are opened. At the bottom inside the circular groove 103, a first electromagnet 104 is fixedly connected. The sliding positioning assembly 3 includes a sliding positioning plate 301. On the front surface of the sliding positioning plate 301, a square sliding groove 302 is opened. Inside the square sliding groove 302, a sliding limiting groove 303 is opened. On the side of the sliding positioning plate 301 close to the fiber splitting assembly 2, a connection positioning groove 304 is opened;

[0043] The controller 4 includes a collection terminal 401, a peak calculation terminal 402, a matching end 403, and a switch 404. The switch 403 is in signal connection with the first electromagnet 104.

[0044] The fiber splitting assembly 2 includes a fiber splitting module 201. On the front surface of the fiber splitting module 201, an access port 202 is fixedly connected. On the back surface of the fiber splitting module 201, a shunt port 203 is fixedly connected. On both sides of the fiber splitting module 201, 204 is fixedly connected. On the side of 204 away from the fiber splitting module 201, a sliding plate 205 is fixedly connected. On the front surface of the sliding plate 205, a connection positioning plate 207 is fixedly connected. On the back surface of the connection positioning plate 207, a second electromagnet 208 is fixedly connected. On the back surface of the sliding plate 205, a limiting plate 206 is fixedly connected.

[0045] There is an interference fit between the diameter of the second electromagnet 208 and the diameter of the circular groove 103. The magnetic pole orientation of the second electromagnet 208 is the same as that of the first electromagnet 104. There is an interference fit between the cross-sectional dimension of the square sliding groove 302 and the cross-sectional dimension of the sliding plate 205. There is an interference fit between the cross-sectional dimension of the sliding limiting groove 303 and the cross-sectional dimension of the limiting plate 206. There is an interference fit between the cross-sectional dimension of the connection positioning groove 304 and the cross-sectional dimension of 204.

[0046] The calculation process of the real-time peak data of the output flow carried by the box body is as follows:

[0047] Step 1: Screen the characteristics of the terminal data collected by the collection terminal 401 to obtain the total number of users, the total number of single-user windows, the time window, the concurrency coefficient, and the redundancy coefficient;

[0048] Specifically: The total number of user windows specifically refers to the maximum number of network ports that a user can connect to. The time window refers to dividing continuous traffic data into multiple small segments according to a fixed time length for analysis, which is used for real-time monitoring and calculating the network traffic peak. It is the core parameter of dynamic traffic management and directly affects the accuracy and response speed of traffic prediction. Both the concurrency coefficient and the redundancy coefficient are existing conventional coefficients, and the setting in this embodiment is between 1 and 2.

[0049] Step 2: Single-user calculation: Import the data in Step 1 into the basic peak calculation model:

[0050]

[0051] Among them, B i is the total number of any user window, t i is the time window of any user, m i is the time window, x i The redundancy coefficient is, y i is the single-user traffic peak number;

[0052] Step 3: Regional user calculation: Adopt mean processing based on the single-user traffic peak number, that is, the calculation formula is:, where i is any user, n is the total number of users, and Y is the regional user traffic peak;

[0053] Step 4: Calculate the time fluctuation coefficient, based on the relationship between the ratio of the active window number to the total window number and the time fluctuation, where the time change constant is one to two times the historical data relationship, that is: M is the time fluctuation coefficient, ai is the active window number at any time point, and Δt is any time period;

[0054] Step 5: Calculate the theoretical real-time traffic peak based on the time fluctuation coefficient and the regional user traffic peak, that is: Y i = Y * M;

[0055] Step 6: Real-time traffic comparison: Compare the real-time collected traffic peak with the theoretical real-time traffic peak, and output the comparison result to the matching end 403.

[0056] Furthermore, the comparison process in Step 6 is as follows:

[0057] 1) Output the electrical signal to the user terminal when the real-time acquisition traffic peak is greater than half of the theoretical real-time traffic peak, and remind to switch the upper fiber optic cable. If the switch is completed, then make a comparison until the real-time acquisition traffic peak is less than half of the theoretical real-time traffic peak;

[0058] 2) When the real-time acquisition traffic peak is less than half of the theoretical real-time traffic peak, no information terminal reminder is made, and the switch is normally executed;

[0059] 3) Normal switching process: The logic is: Based on the theoretical real-time traffic peak, perform a fluctuating switch with the peak change inflection point as the switching time end.

[0060] The normal switching process: Based on the matching end, the electrical signal output by the peak calculation terminal 402 is matched to the switch 403 of the first electromagnet 104 corresponding to the switching process.

[0061] It needs to be further explained in this embodiment that the time gap of the switching process is at the millimeter level, and the implemented network disconnection process has little impact on the polar region. In addition, this embodiment is applicable to the residential user terminal. Moreover, regarding the design quantity of the peak change inflection point, the number per working day does not exceed three to avoid excessive adjustment.

[0062] The working principle of the present invention:

[0063] The mechanical process is as follows: When working, the optical cable needs to be connected to the access port 202, and then the optical cable can be connected through the shunt port 203 for fiber splitting. Through electronic control, the 204, the sliding plate 205, and the limiting plate 206 drive the fiber splitting assembly 2 to move backward along the square sliding groove 302, the sliding limiting groove 303, and the connecting positioning groove 304. When the second electromagnet 208 contacts the first electromagnet 104, the power supply is turned on so that the second electromagnet 208 and the first electromagnet 104 have magnetic force to position the fiber splitting assembly 2, and the fiber splitting assembly 2 can be moved forward through electronic control to facilitate the wiring work of the optical cable distribution box, thus facilitating the user to use;

[0064] The control process is as follows: Real-time data acquisition stage

[0065] The acquisition terminal 401 continuously monitors the network status and obtains the following core parameters:

[0066] The number of online users n of the user terminal, the time window data ti, usually set to 5 - 60 seconds, the active status Bi of each user within the time window, the concurrency coefficient mi of the network environment parameters, and the redundancy coefficient xi; Flow peak calculation stage

[0067] The peak calculation terminal 402 performs multi-level operations: calculates the peak value of single-user traffic: yi = (Bi × mi × xi) / ti, obtains the regional traffic reference value: Y = (∑yi) / n, calculates the time fluctuation coefficient: M = (∑ai / T) × k, where k is the historical coefficient of 1 - 2 times, and obtains the theoretical real-time peak value: Y theory = Y × M

[0068] Flow status determination stage

[0069] The system compares the real-time collected data with Y theory:

[0070] 1 When the real-time traffic > 50% of Y theory: Trigger a first-level response

[0071] 2 When the real-time traffic ≤ 50% of Y theory: Maintain the current configuration

[0072] 3 When the traffic inflection point appears: Predictively adjust the configuration

[0073] Electromagnetic drive switching stage

[0074] The matching end 403 controls the electromagnetic mechanism according to the determination result:

[0075] Send a control signal to the switch 404 of the target first electromagnet 104

[0076] The first electromagnet 104 and the corresponding second electromagnet 208 generate like-pole repulsion

[0077] Under the action of the repulsive force, the sliding plate 205 precisely displaces along the square sliding groove 302

[0078] The limiting plate 206 cooperates with the sliding limiting groove 303 to ensure the stability of the moving track

[0079] Optical path reconstruction stage

[0080] The fiber splitting component 201 completes the physical position adjustment:

[0081] The displacement of the sliding plate 205 drives the overall movement of the fiber splitting module 201, and the access port 202 and the splitting port 203 are re-docked to the target optical fiber; the connection positioning plate 207 and the connection positioning groove 304 are used to achieve precise positioning, and the time consumed for establishing the new optical path is controlled within 100 ms

[0082] Status feedback stage

[0083] The system implements closed-loop control:

[0084] Real-time verify the traffic load situation of the new channel. If the traffic still exceeds the threshold after the switch, start the backup link switch, record the switching parameters of this time for optimizing the subsequent calculation model, and regularly calibrate the sensitivity of the electromagnet magnetic force holding mechanism
