Description

Technical Field

[0001] This invention belongs to the field of power construction technology, specifically relating to a cable bracket and its usage method. Background Technology

[0002] Cables bear the responsibility of transmitting electrical energy, and in cable line construction, cable supports, as supporting components for cable installation, are of paramount importance. However, most cable supports have a relatively simple functional structure and poor adaptability. Once the cable supports are manufactured and installed, they cannot be adjusted again to suit the required cable installation height, and different sized cables require the manufacture of corresponding cable supports, which is extremely cumbersome.

[0003] Existing technology publication CN115411685A provides a cable bracket, which includes a support frame. The rear end of the support frame is a sliding block, and the front end is a retractable buffer portion. The buffer portion is provided with a first fixing ring for mounting cables. The sliding block is fitted inside a column and slides up and down along the column. A locking device for fixing and limiting the sliding block is installed on the column. This makes the cable bracket structure simple, reliable, and easy to assemble, significantly improving the adaptability of the cable bracket design and reducing the manufacturing and installation costs.

[0004] While the existing technical solutions described above can achieve the relevant beneficial effects through their structure, they still have the following drawbacks: 1. Fixing the cable with only one main cable bracket is insufficient in strength, and after long-term use, the cable is prone to loosening or sagging. 2. It is impossible to monitor and promptly detect abnormal conditions during cable use, such as cable damage, cable theft, cable sabotage, fire, etc. Summary of the Invention

[0082] The working principle of the above structure is as follows: First, the fixed base 1 is fixed to a suitable position and height; the synchronous drive mechanism 6 is activated to make the right auxiliary positioning mechanism 4 and the left auxiliary positioning mechanism 8 move synchronously in opposite directions, so that the right auxiliary positioning mechanism 4 and the left auxiliary positioning mechanism 8 move outward synchronously to a suitable distance; the distance between the right sliding base 2 and the left auxiliary positioning mechanism 8 and the main positioning mechanism 3 is measured by a laser rangefinder; then, the width of the main positioning mechanism 3 is added to obtain the distance between the right sliding base 2 and the left auxiliary positioning mechanism 8; then, the right sliding base 2 and the left sliding base 7 are fixed. The lifting drive mechanism 5 drives the main positioning mechanism 3, the right auxiliary positioning mechanism 4 and the left auxiliary positioning mechanism 8 to move up and down to adjust to a suitable height. Then, the main positioning mechanism 3, the right auxiliary positioning mechanism 4 and the left auxiliary positioning mechanism 8 are used to fix the cable to prevent the cable from loosening or sagging. The abnormal monitoring device monitors abnormal conditions during cable use; when cable damage, fire, cable sagging, cable theft, or cable destruction are detected, the alarm module will issue an alarm in a timely manner.

[0083] The synchronous drive mechanism 6 enables the right auxiliary positioning mechanism 4 and the left auxiliary positioning mechanism 8 to move synchronously in opposite directions. The distance can be adjusted as needed, ensuring precise positioning of the bracket. The lifting drive mechanism 5 allows the main positioning mechanism 3 and the auxiliary positioning mechanisms to be flexibly adjusted to suitable heights to adapt to different installation environments. The fixing of the right sliding base 2 and the left sliding base 7, along with the coordinated action of the main positioning mechanism 3, the right auxiliary positioning mechanism 4, and the left auxiliary positioning mechanism 8, effectively prevents cable loosening or sagging, improving cable safety. The anomaly monitoring device can monitor various abnormal conditions during cable use in real time, including damage, fire, sagging, theft, and vandalism. Automated and intelligent bracket adjustment and monitoring reduce the frequency and workload of manual inspections, improving cable management efficiency.

[0084] In an optional embodiment, the cable bracket further includes an anomaly monitoring device. The anomaly monitoring device specifically includes:

[0085] The data collection module is used to collect a large number of images of cables in normal use and in abnormal conditions, as well as images of the environment around the cables; and to label the collected images as basic data and training samples for subsequent image processing and recognition; among them, abnormal conditions include cable damage, fire, cable sagging, cable theft and cable destruction, etc.

[0086] The image acquisition module may include a high-definition camera and LED lights, used to acquire high-definition real-time images of the cable and the surrounding environment;

[0087] The image preprocessing module is used to preprocess the acquired real-time images, including filtering and denoising, grayscale conversion, and normalization.

[0088] The anomaly detection module is used to extract and analyze features from preprocessed real-time images to identify anomalies. Specifically, it can use machine learning or deep learning algorithms to identify anomalies such as cable damage, cable theft, cable destruction, and fire.

[0089] Temperature measurement module, including an infrared thermometer, is used to measure the temperature of the cable;

[0090] The cable sag analysis module is used to extract and analyze features from preprocessed real-time images, identifying and promptly determining cable sag conditions. The module primarily identifies cable sag based on the cable's geometric shape. It can determine the degree of sag and whether it exceeds the normal range.

[0091] The risk assessment module combines the results from the cable temperature, anomaly identification, and cable sag analysis modules to comprehensively assess the abnormal risks of the cable. Based on preset rules or algorithms, it determines the degree of danger of the cable's current state and provides a corresponding risk level.

[0092] The alarm module will issue an alarm when it detects cable damage, fire, cable sagging, cable theft, or cable tampering.

[0093] The control center is network-connected to the data collection module, image acquisition module, image preprocessing module, anomaly recognition module, cable sag analysis module, and alarm module.

[0094] The above technical solution enables comprehensive monitoring and anomaly identification of cable conditions. It not only promptly detects cable abnormalities but also issues alarms, providing strong protection for the safe operation of cables.

[0095] In the optional solution, the anomaly detection module performs feature extraction and analysis on the preprocessed real-time image to identify anomalies, as follows:

[0096] (1) Feature extraction: Using image processing technology and machine learning algorithms, extract features that are useful for identifying anomalies from real-time images; features may include color, texture, shape, edge, etc.

[0097] (2) The extracted features are analyzed using the random forest algorithm to identify anomalies in the image.

[0098] Specifically, when using random forests for feature analysis, the decision for each tree can be constructed based on samples in the feature space; for the i-th tree, the decision function is expressed as:

[0099]

[0100] h ij（x） =П[ x k ≤θ ij ]

[0101] In the formula, f i ( x Let represent the decision function of the i-th tree, used to predict the label of sample x. J i This represents the total number of split nodes in the i-th tree (excluding leaf nodes). This represents the weight or split strength at the j-th split node in the i-th tree, learned during training, and used to quantify the node's contribution to the final decision. The splitting function or splitting condition for the j-th node of the i-th tree is a function that determines whether a sample should be assigned to the left or right subtree based on the value of feature x. h ij ( x ) is a threshold function; x k It is a feature x The k One dimension, θ ij is the threshold at that node; П is an indicator function that returns 1 when the condition is met, and 0 otherwise. i The bias term (or intercept) of the i-th tree is a constant used to adjust the position of the decision boundary.

[0102] (3) Anomaly identification: Based on the results of feature analysis, determine whether there are any anomalies in the image and identify the type of anomaly (such as cable damage, cable theft, cable destruction, fire, etc.). Output the anomaly identification results, including anomaly type, location, severity, and other information.

[0103] In an optional approach, the anomaly detection module can also use CNN for image feature extraction and preliminary classification, and then combine it with SVM classification algorithm for fine classification, including the following steps:

[0104] Building a CNN model: Design the number of layers and parameters of the CNN; including convolutional layers, activation layers (such as ReLU), pooling layers (such as Max Pooling), and fully connected layers. The last layer uses the softmax activation function for initial classification (normal / abnormal), and the output layer is designed to be suitable for feature extraction.

[0105] CNN Model: Train the CNN model using the training set data. Optimize model performance by tuning hyperparameters using the validation set.

[0106] Feature extraction: Use a trained CNN model to extract features from the image to obtain feature vectors.

[0107] An SVM classifier uses feature vectors extracted from a CNN as input to classify these vectors, resulting in a more refined classification (normal / specific types of anomalies). For data classified as "anomalies" by the SVM, the differences between their feature vectors and those of normal data are analyzed. Statistical methods (such as calculating the distance of the feature vectors to the mean or median of the normal dataset) are used to quantify these differences, identifying outliers that are significantly different from the normal data.

[0108] Optionally, when training the SVM classifier, normal and abnormal data can be used as training sets. Appropriate kernel functions (such as RBF, linear, etc.) and parameters (such as C, gamma, etc.) should be selected.

[0109] Optionally, the feature extraction capability of the CNN and the classification accuracy of the SVM are evaluated using a test set. Metrics such as confusion matrix, accuracy, recall, and F1 score can be used for evaluation. Based on the evaluation results, the parameters of the CNN and SVM are adjusted to optimize model performance.

[0110] Optionally, the data for the training set, test set, and validation set come from the data collection module.

[0111] Optionally, the cable sag analysis module is specifically used to: extract edge information from the cable image using an edge detection algorithm; calculate geometric parameters such as the cable's curvature and tilt angle based on the edge information; and analyze the cable's sag. A threshold for the degree of sag is set based on factors such as the cable's specifications, materials, and voltage level; this threshold can be determined through experimental data, national standards, or empirical values. The extracted cable geometric parameters are compared with the set threshold to determine whether the cable's sag exceeds the normal range. The edge detection algorithm can be the Canny algorithm.

[0112] Alternatively, geometric parameters can be extracted and calculated using image processing algorithms such as Hough transform and least squares method.

[0113] Optionally, the risk assessment module combines the results from the cable temperature, anomaly identification, and cable sag analysis modules to comprehensively assess the abnormal risks of the cable, including the following steps:

[0114] (1) Data collection and preprocessing: Collect cable temperature data, clean the temperature data, and remove outliers or noise data. Receive the output results from the anomaly identification module, including the detected cable anomaly type, location, and severity. Collect the results from the cable sag analysis module, and obtain real-time cable sag status data from the cable sag analysis module, including parameters such as sag amount and sag speed.

[0115] (2) Risk assessment model construction: Based on the actual operation of the cable and safety requirements, define risk assessment indicators, such as temperature anomaly threshold, anomaly type severity score, sag safety standard, etc.

[0116] The comprehensive evaluation algorithm uses cable temperature, anomaly identification results, and cable sag analysis results as input variables. A weighted average comprehensive evaluation method is then used to integrate the evaluation results of each input variable into a comprehensive anomaly risk value for the cable.

[0117] The overall anomaly risk value is calculated using the following formula:

[0118] Rcomprehension = wT*RT + wS*RS + wL*RL

[0119] wT+wS+wL=1

[0120] Among them, Rcomprehensive is the comprehensive risk value, representing the overall risk level of the cable, which is obtained by weighted summation of the risk values ​​of each independent risk factor. wT is the weight of temperature anomaly, representing the contribution of temperature anomaly to the comprehensive risk value; RT is the risk value of temperature anomaly, representing the risk level of the current cable temperature state relative to the temperature anomaly threshold. wS is the weight of anomaly type severity, representing the contribution of anomaly type severity to the comprehensive risk value. RS is the risk value of anomaly type severity, representing the severity of the current cable anomaly type. wL is the weight of sag safety, representing the contribution of sag to the comprehensive risk value. RL is the risk value of sag safety, representing the risk level of the current cable sag state relative to the safety standard.

[0121] Optionally, R, as a primary indicator, has scores that directly correspond to different risk levels. RT, RS, and RL, as secondary indicators, can each have corresponding tertiary indicators; each tertiary indicator has its own weight, and the secondary indicators can be obtained by weighted summation of the scores of the tertiary indicators and their corresponding weights.

[0122] (3) Output the cable abnormality risk value and its corresponding risk level (such as low risk, medium risk, high risk, etc.) for each assessment period.

[0123] This invention provides a method for using a cable bracket, comprising the following steps:

[0124] S1. First, fix the fixed base 1 to the appropriate position and height;

[0125] S2. Then, start the synchronous drive mechanism 6 to make the right auxiliary positioning mechanism 4 and the left auxiliary positioning mechanism 8 move synchronously in opposite directions, so that the right auxiliary positioning mechanism 4 and the left auxiliary positioning mechanism 8 move outward synchronously to a suitable distance; measure the distance between the right sliding base 2 and the left auxiliary positioning mechanism 8 and the main positioning mechanism 3 using a laser rangefinder; then add the width of the main positioning mechanism 3 to obtain the distance between the right sliding base 2 and the left auxiliary positioning mechanism 8.

[0126] S3. Then fix the right sliding base 2 and the left sliding base 7.

[0127] S4. The lifting drive mechanism 5 drives the main positioning mechanism 3, the right auxiliary positioning mechanism 4 and the left auxiliary positioning mechanism 8 to move up and down to adjust to a suitable height.

[0128] S5. Then, the cable is fixed by the main positioning mechanism 3, the right auxiliary positioning mechanism 4 and the left auxiliary positioning mechanism 8 to prevent the cable from loosening or sagging.

[0129] S6. The anomaly monitoring device monitors abnormal conditions during the use of the cable;

[0130] S7. The risk assessment module combines the results of the cable temperature, anomaly identification, and cable sag analysis modules to comprehensively assess the potential anomaly risks of the cable.
