[0346] As Figure 2 shown, the present invention also proposes a full-process on-site operation online control system, including the following modules:

[0352] According to the above five modules, the interaction relationship parameter table between the modules is as follows:

[0353]

[0354] In the table, the arrow → represents active data push (such as coordinates, model parameters), the arrow ← represents passive parameter call (such as conflict analysis to retrieve historical data), and the arrow ↔ represents two-way policy dependence (such as bandwidth allocation and positioning weight iteration);

[0355] Through the above system, perform the following application scenarios: Emergency repair operation of mountain transmission lines;

[0356] Scenario background: Due to lightning strikes, there are potential hazards of insulator breakage in a 220kV transmission line in a mountainous area. The maintenance team carried edge terminals into the site. The 5G signal in the operation area fluctuated violently due to terrain occlusion (bandwidth fluctuation range 20~80Mbps). It is necessary to synchronize the potential hazard coordinates, equipment status, and maintenance progress to the cloud digital twin system and ensure real-time and accurate alarm of the electronic fence.

[0357] Step 1: Dynamic bandwidth allocation

[0358] Channel quality monitoring: The edge terminal continuously monitors the signal strength and detects that the real-time bandwidth suddenly drops to 35Mbps ( =35), signal-to-noise ratio =8dB, packet loss rate =12%, calculate the channel quality coefficient = 0.52 (below the threshold of 0.6), triggering a deterioration warning;

[0359] Data priority sorting: Comparing the difference between edge / cloud data = 82 (the weight of the maintenance progress difference accounts for 60%), dynamically allocated = 28 Mbps;

[0360] Maintenance task data (insulator model, operation specifications) preferentially occupy 20 Mbps of bandwidth;

[0361] Cache mechanism intervention: Calculating the synchronization delay = 9 seconds, exceeding the tolerance threshold = 5 seconds, 15% of the vibration spectrum data is temporarily stored locally;

[0362] Step 2: Positioning compensation

[0363] Coordinate anomaly detection: The deviation between the Beidou coordinates (118.6523°, 27.8915°) at the edge and the cloud GIS benchmark = 1.2 meters, exceeding = 0.5 meters threshold, starting the compensation mechanism;

[0364] Historical trajectory correction: Retrieving the trajectory data of the previous 5 minutes , generating compensation coordinates (118.6521°, 27.8912°) through cubic spline interpolation, and the deviation after compensation = 0.38 meters, and the accuracy of the electronic fence meets the standard;

[0365] Step 3: Model calibration

[0366] Abnormal life prediction: The digital twin model predicts the remaining life of the insulator = 6.3 years, the actual value = 5.1 years, the deviation rate = 23.5% far exceeds the 10% threshold

[0367] Implementation of incremental learning: Loading the TensorFlow Lite model, fusing the vibration data of the last 2 hours Carrying out training to generate a gradient matrix , and transmitting it back to the cloud after 30% sparse compression;

[0368] Global model update: The cloud fuses the gradient update parameters , calibrating the predicted life, = 5.2 years, and the deviation rate drops to 1.96%;

[0369] Step 4: Early warning linkage

[0370] Out-of-bounds Event Disposal: When maintenance personnel approach the non-powered area (coordinates 1.8 meters away from the live conductor), the electronic fence triggers a level-three audible and visual alarm, and the false alarm rate monitoring shows = 18% (positioning jitter caused by shrubbery obstruction);

[0371] Multi-source Verification to Reduce False Alarms: By fusing the RFID coordinates of the safety helmet (118.6520°, 27.8910°) and the UAV aerial photography coordinates, the final position is corrected, and the false alarm rate is reduced to = 3.7%, and the alarm accuracy rate meets the standard;

[0372] Step 5: Policy Optimization

[0373] Analysis of Conflict Events: Extract 37 synchronous conflict events in this operation and find that when < 0.6 and > 50, the cache failure probability reaches 89%;

[0374] Upgrade of the Rule Base: Increase the maintenance task weight from 0.6 to 0.7, and add a cache ratio formula for the scenario of channel degradation: ;

[0375] Verification of Effectiveness: After the policy update, the synchronous delay in the same area is reduced from 9 seconds to 3.8 seconds (a decrease of 57.8%), and the model drift repair response time is shortened to 8 minutes.

[0376] Closed-loop Effect: Through the five-level joint control mechanism, in a 5G fluctuating environment, the integrity rate of key data synchronization is increased from 68% to 94%, the number of accidental touches on the electronic fence is reduced from 12 times per day to 2 times per day, the hidden danger disposal efficiency is increased by 41%, and 6 optimization strategies are formed and incorporated into the 5G communication implementation guide;

[0377] The specific effect comparison table is as follows:

[0378]

[0379] This system, through a five-level modular design, achieves in a 5G unstable mountainous environment: a 47% improvement in the hidden danger disposal timeliness (compared with the traditional solution), an extension of the communication interruption tolerance duration to 8.3 minutes, and a control of the synchronous conflict recurrence rate below 2.1%.
