[0040] The working principle of the above structure is as follows: first, fix the fixed base 1 to a suitable position and height; start the synchronous driving mechanism 6 to make the right auxiliary positioning mechanism 4 and the left auxiliary positioning mechanism 8 move synchronously in the opposite direction, so that the right auxiliary positioning mechanism 4 and the left auxiliary positioning mechanism 8 move synchronously outward 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 by 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; then fix the right sliding base 2 and the left sliding base 7. The lifting driving 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 a suitable height.

Through the use of the lifting drive mechanism 5, the main positioning mechanism 3 and the auxiliary positioning mechanism can be flexibly adjusted to a suitable height to adapt to different installation environments. Through the fixation of the right sliding base 2 and the left sliding base 7, and the coordinated action of the main positioning mechanism 3, the right auxiliary positioning mechanism 4 and the left auxiliary positioning mechanism 8, the cable is effectively prevented from loosening or sagging, thereby improving the safety of cable use. The abnormal monitoring device can monitor various abnormal conditions in the use of the cable in real time, including breakage, fire, sagging, theft and destruction. Through automated and intelligent bracket adjustment and monitoring, the frequency and workload of manual inspections are reduced, and the efficiency of cable management is improved.

[0042] In an optional embodiment, the cable support further includes an abnormality monitoring device. The abnormality monitoring device specifically includes: The data collection module is used to collect a large number of images of normal cable use and abnormal conditions, as well as images of the cable surrounding environment; and to annotate the collected images as basic data and training samples for subsequent image processing and recognition; abnormal conditions include cable damage, fire, cable sagging, cable theft, and cable destruction; An image acquisition module may include a high-definition camera and an LED light for acquiring high-definition real-time images of the cable and the surrounding environment; Image preprocessing module, used to preprocess the collected real-time images, including filtering, denoising, grayscale and normalization; The anomaly recognition module is used to extract and analyze the features of the pre-processed real-time image and identify abnormal situations. Specifically, machine learning or deep learning algorithms can be used to identify abnormal situations, such as cable breakage, cable theft, cable destruction, and fire. A temperature measurement module, including an infrared thermometer, is used to measure the temperature of the cable; The cable sag analysis module is used to extract and analyze the features of the pre-processed real-time image, analyze and identify the cable sag, and identify the cable sag in time. The module mainly identifies the cable sag based on the geometric shape of the cable. The module can identify the degree of cable sag and determine whether it exceeds the normal range.

[0043] The risk assessment module is used to combine the results of the cable temperature, abnormal identification module and cable sag analysis module to comprehensively evaluate the abnormal risk of the cable. According to the preset rules or algorithms, the danger level of the current state of the cable is judged and the corresponding risk level is given.

[0044] The alarm module will sound an alarm when it detects cable damage, fire, cable sagging, cable theft, and cable destruction; The control center is connected to the data collection module, the image acquisition module, the image preprocessing module, the abnormality recognition module, the cable sag analysis module and the alarm module through a network.

[0045] In the above technical solution, comprehensive monitoring and abnormal identification of the cable status are realized. Not only can the abnormal situation of the cable be discovered in time, but also the abnormal situation can be alarmed, providing a strong guarantee for the safe operation of the cable.

[0046] In the optional solution, the abnormality recognition module extracts and analyzes the features of the pre-processed real-time image to identify abnormal situations, as follows: (1) Feature extraction: Use image processing technology and machine learning algorithms to extract features useful for identifying anomalies from real-time images; features can include color, texture, shape, edges, etc.

[0047] (2) The extracted features are analyzed through the random forest algorithm to identify abnormalities in the image.

[0048] Specifically, when using random forest for feature analysis, the decision of each tree can be constructed based on the samples in the feature space; for the i-th tree, the decision function is expressed as:

[0049] h ij（x） =П[ x k ≤θ ij ] In the formula, f i ( x ) represents the decision function of the i-th tree, which is used to predict the label of sample x. J i Represents the total number of split nodes in the i-th tree (excluding leaf nodes). Represents the weight or split strength at the j-th split node in the i-th tree, which is learned during the training process and is used to quantify the contribution of the node to the final decision. The splitting function or splitting condition of the jth node of the i-th tree is a function that determines whether the sample should be assigned to the left subtree or the right subtree based on the value of the feature x. h ij ( x ) is a threshold function; x k It is a feature x No. k dimensions, θ ij is the threshold value at the node; П is the indicator function, which returns 1 when the condition is met, otherwise it returns 0. i Represents the bias term (or intercept) of the i-th tree, which is a constant used to adjust the position of the decision boundary.

[0050] (3) Abnormal situation identification: Based on the results of feature analysis, determine whether there are abnormal situations in the image and determine the type of abnormality (such as cable damage, cable theft, cable destruction, fire, etc.). Output the identification results of the abnormal situation, including abnormality type, location, severity and other information.

[0051] In an optional solution, the anomaly recognition module can also use CNN to extract image features and perform preliminary classification, and then combine the SVM classification algorithm for fine classification, including the following steps: Construct CNN model: Design the number of CNN layers and parameters, 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 preliminary classification (normal / abnormal), and the output layer is designed to be suitable for feature extraction.

[0052] CNN model: Use the training set data to train the CNN model. Use the validation set to adjust the hyperparameters and optimize the model performance.

[0053] Extract features: Use the trained CNN model to extract features from the image and obtain a feature vector.

[0054] SVM classifier is used to classify the feature vector extracted from CNN as the input data of SVM classifier to obtain more refined classification results (normal / specific type of abnormality). For data classified as "abnormal" by SVM, the difference between its feature vector and the feature vector of normal data is analyzed. Statistical methods (such as calculating the distance of the feature vector to the mean or median of the normal data set) are used to quantify the difference and identify abnormal points that are significantly different from normal data.

[0055] Optionally, when training the SVM classifier, the normal data and the abnormal data are used as training sets to train the SVM classifier. An appropriate kernel function (such as RBF, linear, etc.) and parameters (such as C, gamma, etc.) are selected.

[0056] Optionally, use the test set to evaluate the feature extraction ability of CNN and the classification accuracy of SVM. You can use confusion matrix, accuracy, recall, F1 score and other indicators to evaluate. Adjust the parameters of CNN and SVM according to the evaluation results to optimize the model performance.

[0057] Optionally, the data of the training set, the test set, and the validation set come from a data collection module.

[0058] Optionally, the cable sag analysis module is specifically used to: use an edge detection algorithm to extract edge information of the cable image, calculate the cable's curvature, tilt angle and other geometric parameters based on the edge information, and analyze the cable's sag. According to factors such as the cable's specifications, materials, and voltage levels, a threshold for the sag degree is set, which can be determined by experimental data, national standards, or empirical values. The extracted cable geometric parameters are compared and analyzed with the set thresholds to determine whether the cable's sag degree exceeds a normal range. The edge detection algorithm can be a Canny algorithm.

[0059] Alternatively, geometric parameters can be extracted and calculated by image processing algorithms (eg Hough transform, least squares method).

[0060] Optionally, the risk assessment module combines the results of the cable temperature, the abnormality identification module and the cable sag analysis module to comprehensively assess the abnormality risk of the cable, including the following steps: (1) Data collection and preprocessing: Collect cable temperature data, clean the temperature data, and remove outliers or noise data. Receive the output results of the anomaly recognition module, including the type, location, and severity of the detected cable anomaly. Collect the results of the cable sag analysis module and obtain the real-time sag status data of the cable from the cable sag analysis module, including parameters such as sag amount and sag speed.

[0061] (2) Risk assessment model construction: Based on the actual situation and safety requirements of cable operation, risk assessment indicators are defined, such as temperature anomaly threshold, anomaly type severity score, sag safety standard, etc.

[0062] Through the comprehensive evaluation algorithm, the cable temperature, abnormal identification results and cable sag analysis results are used as input variables. Through the weighted average comprehensive evaluation method, the evaluation results of each input variable are integrated into the comprehensive abnormal risk value of the cable.

[0063] The comprehensive abnormal risk value is calculated according to the following formula: R comprehensive = wT*RT+wS*RS+wL*RL wT+wS+wL=1 Among them, R is the comprehensive risk value, which indicates the overall risk level of the cable, and is obtained by weighted summing the risk values ​​of each independent risk factor. wT is the weight of temperature anomaly, which indicates the contribution of temperature anomaly to the comprehensive risk value; RT is the risk value of temperature anomaly, which indicates the risk level of the current cable temperature state relative to the temperature anomaly threshold. wS is the weight of the severity of the anomaly type, which indicates the contribution of the severity of the anomaly type to the comprehensive risk value. RS is the risk value of the severity of the anomaly type, which indicates the severity of the current cable anomaly type. wL is the weight of the sag safety, which indicates the contribution of the sag to the comprehensive risk value. RL is the risk value of the sag safety, which indicates the risk level of the current cable sag state relative to the safety standard.

[0064] Optionally, R is used as a first-level indicator, and its score directly corresponds to different risk levels. RT, RS and RL are second-level indicators, and they can also correspond to third-level indicators respectively; the third-level indicators correspond to their own weights, and the second-level indicators can be obtained by weighted summing the scores of the third-level indicators and the corresponding weights.

[0065] (3) Output the cable abnormality risk value and its corresponding risk level (such as low risk, medium risk, high risk, etc.) for each assessment cycle.

[0068] 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 being loosened or sagging.
