[0094] The edge computing unit is further configured to perform dimensionality reduction feature extraction on the working status data to obtain feature data, including:

[0095] Principal Component Analysis (PCA): Projects multidimensional features into a low-dimensional space, retaining the principal components with 95% variance, and reducing computational complexity.

[0096] It should be noted that the edge computing unit is further configured to perform at least one of the following:

[0097] Perform Z-Score standardization on the characteristic data (such as vibration amplitude, temperature, etc.) to eliminate dimensional differences;

[0098] The mutual information method is used to filter the feature data that is strongly correlated with the fault label and eliminate redundant dimensions.

[0099] A sliding window mechanism is used to update the feature data every 100ms to balance the computing load and response speed.

[0100] For example, the edge computing unit extracts the following feature data in real time during the operation of the optical cable concentric yarn binding machine and uploads the feature data to the cloud platform. By comparing the feature data with the fault feature library, typical problems such as early faults and abnormal yarn tension can be accurately diagnosed to achieve predictive maintenance:

[0101] Vibration: X-axis vibration kurtosis of the bearing seat (>3.5 triggers an early warning);

[0102] Noise: MFCC 4th dimension coefficient (abnormal voiceprint matching degree > 80%);

[0103] Temperature: Motor winding temperature gradient (>5°C / cm);

[0104] Current: 5th harmonic content (>7%).

[0105] Furthermore, the edge computing unit is further configured to perform data compression and encryption on the feature data, wherein:

[0107] Encryption: AES-128 end-to-end encryption is used to ensure the confidentiality of the characteristic data during transmission.

[0108] Furthermore, the feature data is uploaded to the cloud via a low-latency transmission protocol (such as MQTT over TLS protocol), and 5G network slicing technology is used to ensure sub-second transmission delay.

[0109] After receiving the feature data, the cloud platform performs data integrity verification (such as CRC check) on the feature data, and if the data integrity verification passes, decrypts the feature data to obtain the decrypted feature data.

[0110] It should be noted that, after obtaining the decrypted feature data, the cloud platform is configured to perform at least one of the following processing on the decrypted feature data:

[0115] Feature fusion: Combine the vibration spectrum and current harmonic feature data to construct composite feature data;

[0116] Principal Component Analysis (PCA): retaining 95% of the variance of the principal components, reducing the dimension of the feature data to 10 to 20 dimensions;

[0117] t-SNE visualization: Identifying clusters of potential failure modes in high-dimensional feature space.

[0118] In one embodiment, optionally, the fault diagnosis model is used to obtain the fault diagnosis result based on the similarity between the feature data and the fault samples in the fault feature library.

[0119] In an embodiment of the present invention, the fault diagnosis model may adopt a random forest model or a long short-term memory network.

[0120] The fault diagnosis result is obtained by matching the fault feature library with the fault diagnosis model.

[0121] It should be noted that if the similarity between the characteristic data and the fault sample exceeds a first similarity threshold, the fault diagnosis result obtained is the fault type corresponding to the fault sample.

[0122] If the similarities between the characteristic data and the plurality of fault samples all exceed the first similarity threshold, the fault diagnosis results are sorted according to the predicted probabilities, and a probability sorting list is output.

[0123] If the similarity between the characteristic data and all fault samples in the fault characteristic library is less than a second similarity threshold, a warning of a new fault type is triggered to achieve unknown fault detection. The second similarity threshold is less than the first similarity threshold.

[0124] The fault feature library includes characteristic data of typical faults such as bearing wear and belt slippage. The construction process of the fault feature library is as follows:

[0125] Historical data labeling: Using expert experience and semi-supervised learning, thousands of historical fault samples are labeled (such as bearing wear, yarn breakage, and motor overheating);

[0126] Feature extraction: Generate standardized feature data using the same method as the edge computing unit;

[0127] Cluster analysis: Use the DBSCAN algorithm to cluster unlabeled data and discover unknown failure modes.

[0128] Here, the following similarity matching algorithm is used to obtain the similarity between the feature data and the fault samples in the fault feature library:

[0129] Cosine similarity: Calculate the cosine value of the angle between the feature data and each fault sample in the fault feature library, and select the top-K similar samples;

[0130] Dynamic Time Warping (DTW): measures the similarity between sequences for time series feature data (such as vibration signal segments);

[0131] Deep Learning Model: Deploy a pre-trained Siamese network and learn the distance metric in the feature embedding space through a Siamese neural network.

[0132] In one embodiment, optionally, the cloud platform is further configured to perform incremental training on the fault diagnosis model at intervals of a preset duration.

[0133] In an embodiment of the present invention, the cloud platform is also used to update the fault feature library using an online learning algorithm (such as incremental SVM) for newly confirmed fault cases (after manual review) at preset time intervals to optimize classification accuracy.

[0134] and / or,

[0135] The cloud platform is also used to retrain the fault diagnosis model with all historical data at preset intervals (such as weekly) to improve long-term accuracy.

[0136] In one embodiment, optionally, the cloud platform is further configured to determine a fault warning level of the optical cable concentric yarn binding machine based on the characteristic data, the fault diagnosis model, and a dynamically updated fault warning threshold.

[0137] It should be noted that in order to achieve accurate early warning and graded response to the operating status of the optical cable concentric yarn binding machine, the cloud platform described in the embodiment of the present invention is also used to set a multi-level early warning mechanism as shown in Table 1, which corresponds to different response measures respectively, and determines the fault warning level of the optical cable concentric yarn binding machine based on the characteristic data, the fault diagnosis model and the dynamically updated fault warning threshold.

[0138] Table 1: Schematic diagram of multi-level early warning mechanism

[0139]

[0140] The warning level is determined not only based on a single characteristic data point (such as vibration), but also by integrating indicators such as temperature, noise, and current for a comprehensive assessment, improving accuracy. Trend analysis algorithms (such as sliding average, exponential weighting, and long-short-term memory network prediction models) are introduced to identify potential risks before the characteristic data reaches the alarm threshold. Warning information is pushed to operations and maintenance personnel via mobile applications, text messages, or apps, enabling rapid response.

[0141] Therefore, the monitoring system of the optical cable concentric yarn binding machine described in the embodiment of the present invention can accurately identify and warn the operating status of key parts of the optical cable concentric yarn binding machine (such as bearing seats, pulleys, transmission shafts, motors and yarn tension points), effectively reducing the probability of sudden failures.

[0142] In one embodiment, optionally, the cloud platform is further configured to obtain the dynamically updated fault warning threshold according to an adaptive algorithm.

[0143] In an embodiment of the present invention, the dynamically updated fault warning threshold is calculated using the following formula:

[0144] Fault warning threshold = reference fault warning threshold × (1 + 0.015 × ΔT), where ΔT is the deviation between the ambient temperature and the standard operating condition.

[0145] Figure 2 FIG. 1 is a schematic diagram of the architecture of the monitoring system of the optical cable concentric yarn binding machine according to an embodiment of the present invention. Figure 2 As shown, the monitoring system of the optical cable concentric yarn binding machine is aimed at the optical cable concentric yarn binding machine A and the optical cable concentric yarn binding machine B. The bearing seat, motor 1, motor 2 and motor 3 of each of the optical cable concentric yarn binding machines are respectively installed with sensors. For example, the bearing seat includes bearings 1 to bearings 6, and each bearing is installed with a sensor; the motor drive end of each motor is installed with a sensor. Each optical cable concentric yarn binding machine corresponds to an edge computing unit, and the edge computing unit can be an intelligent gateway. The working status data of the optical cable concentric yarn binding machine collected by each sensor is uploaded to the edge computing unit, and the edge computing unit performs data preprocessing and feature extraction on the working status data to obtain feature data, and the feature data is uploaded to the cloud platform. The cloud platform performs fault diagnosis and fault warning on the feature data, and realizes visual interaction.

[0147] Step 301: Acquire feature data of an optical cable concentric yarn binder to be monitored extracted by an edge computing unit, wherein the feature data is related to working status data of the optical cable concentric yarn binder collected by multiple sensors;

[0148] Step 302: Obtain a fault diagnosis result of the optical cable concentric yarn binding machine based on the characteristic data and the trained fault diagnosis model.
