Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power system monitoring, in particular to a cable anti-theft monitoring method and system, computer equipment and storage medium. BACKGROUND

[0002] In the process of social and economic development in China, the supply of various metal resources is becoming increasingly tight. Due to the driving of interests, many unscrupulous people steal power equipment, thus embarking on the road of crime. Power cables play an important role in the power system. Because the value of the cable itself is high, there is a problem of theft in the use process of the cable. Once the cable is stolen, it will cause economic losses much higher than the value of the cable itself. The cable has high reliability in the power supply process and occupies less area, and can be integrated with the environment, so it is widely used in urban power distribution networks. However, due to the large number of floating population in cities, the situation of public security is severe, so high-voltage cables are often stolen, which seriously affects related business enterprises and power supply departments. And after the cable line is damaged, the power performance will gradually decrease, causing equipment failure or power failure.

[0003] At present, with the improvement of technology, the existing cable device usually implants a sensor to accurately determine the stolen position when stolen. When the cable is detected to be cut, the cut cable position information is immediately sent to the microcomputer host. However, this method can only report after failure and cannot give early warning.

[0004] In view of the above problems, a cable anti-theft monitoring method is designed to solve the problem of single cable monitoring mode and lack of reasonable early warning in the prior art. SUMMARY

[0005] In view of the above problems, the present application is proposed.

[0006] Therefore, the technical problem solved by the present application is that the existing cable monitoring method has the problems of single monitoring mode and lack of effective early warning, and how to optimize real-time data analysis and dynamic response.

[0007] To solve the above technical problems, the present application provides the following technical scheme: a cable anti-theft monitoring method, comprising:

[0008] capturing images of the anti-theft area by using a camera and obtaining video information;

[0009] cutting key images from the video information, analyzing objects in the key images, and analyzing displacement data to determine moving tracks and speeds;

[0010] The tension of the cable is measured by detecting the change of the tension through the deformation of the resistance strain gauge.

[0011] The movement trajectory and speed of the target object are compared with the tension parameter of the cable in real time, and it is judged whether the data meets the preset theft behavior standard.

[0012] As a preferred scheme of the cable anti-theft monitoring method, the video information is obtained by arranging a night vision camera, which automatically captures two video frames per second; the captured video frames are automatically adjusted in resolution and contrast enhancement.

[0013] The analysis of the object in the key image includes applying a scene change detection algorithm to automatically extract key frames from the video stream, and running a Faster R-CNN algorithm in each key frame to identify and locate the object in the image.

[0014] The DeepSORT tracking algorithm is applied to the object identified in the key frame to extract the position coordinate sequence of each object from the tracking data provided by the DeepSORT algorithm, and the movement trajectory and speed of the object are output by calculating the change of the continuous coordinates.

[0015] As a preferred scheme of the cable anti-theft monitoring method, the change of the tension is detected by the deformation of the resistance strain gauge, which includes installing a resistance strain gauge at a key stress point of the cable, connecting the resistance strain gauge to a measurement circuit through a wire, calibrating the installed strain gauge and measurement circuit, monitoring the tension of the cable in real time, recording the resistance change data from the strain gauge, and converting the resistance value change to tension parameter.

[0016] As a preferred scheme of the cable anti-theft monitoring method, the real-time comparison includes feature extraction of the movement trajectory and speed data and the tension parameter data of the cable, time synchronization and format unification of the movement trajectory and speed and the tension parameter data, extraction of the average value, maximum value and change rate of the moving speed from the movement trajectory and speed data, and extraction of the peak value and change trend of the tension from the tension parameter.

[0017] The change trend is obtained by linear regression analysis, and is quantified by the slope, where a positive slope represents an increasing trend and a negative slope represents a decreasing trend.

[0018] As a preferred scheme of the cable anti-theft monitoring method, the judgment of whether the data meets the preset theft behavior standard includes constructing a cable anti-theft monitoring model by the data obtained by feature extraction, comparing the model output result Y with the preset threshold value, and if Y is greater than or equal to the preset threshold value, it is judged that a theft behavior has occurred, and if Y is less than the preset threshold value, it is judged that no theft behavior has occurred.

[0019] As a preferred scheme of the cable theft monitoring method, the cable theft monitoring model is represented as,

[0020]

[0021] wherein Y represents the comprehensive score, represents the average speed of the object movement, v max represents the maximum speed of the object recorded in the measurement time window, Δv represents the change rate of the object movement speed, F max represents the maximum pulling force value recorded in the measurement time window, β F represents the slope of the pulling force change trend, a, b, c, d, and e respectively represent the weight coefficients, tanh(·) represents the hyperbolic tangent function, represents the natural logarithmic conversion of the average speed, e c·Δv represents the exponential function with e as the base, sigmoid(β F ) represents the S-shaped logic function, and abs(β F ) represents the absolute value function.

[0022] As a preferred scheme of the cable theft monitoring method, if it is judged that a theft behavior occurs, a data pop-up window of the theft behavior information is triggered, a short message is sent to inform the staff, an alarm prompt sound broadcast is performed in the anti-theft area, and the light is controlled to flash.

[0023] If it is judged that no theft behavior occurs, the identity of the personnel in the anti-theft area is verified and the behavior is analyzed.

[0024] Another object of the present application is to provide a cable theft monitoring system, which can solve the problems of real-time monitoring and early warning response by constructing a cable theft monitoring system.

[0025] To solve the above technical problems, the present application provides the following technical solutions: a cable anti-theft monitoring system, comprising: a target object recognition module, a tension sensor, and an alarm module; the target object recognition module shoots image information of an anti-theft area at a preset time interval through a camera, obtains video information of the anti-theft area, intercepts the image to obtain the image information of the anti-theft area, identifies the objects in the image information to obtain displacement data for identifying the moving track thereof; the tension sensor obtains tension parameter data of the cable through the tension sensor; the elastic element of the tension sensor produces elastic deformation under external force, so that the resistance strain gauges pasted on the surface thereof also produce deformation, the resistance value of the resistance changes with the deformation, the resistance change is converted into a measurable electrical signal through a measurement circuit, so as to obtain the tension parameter data of the cable, and the moving track of the target object is compared with the tension parameter value of the cable; the alarm module matches the comparison result of the tension parameter data and the moving data with a standard for judging a theft behavior, if the comparison result meets the standard of the theft behavior, it is determined that the theft behavior occurs, the alarm module sends a data pop-up window or a short message containing the theft behavior information to a client to timely inform the staff, and at the same time, an alarm prompt sound is broadcasted in the anti-theft area and the light is controlled to flash to deter cable theft personnel.

[0027] A computer-readable storage medium having a computer program stored thereon, the computer program being executed by a processor to implement the steps of the cable anti-theft monitoring method as described above.

[0028] The cable anti-theft monitoring method provided by the present application can significantly improve the cable anti-theft efficiency and response speed. By integrating video monitoring and tension sensing technology, the cable state can be monitored in real time from multiple dimensions, not only the change of the cable position can be detected, but also the change of the cable force can be perceived, so that early warning of potential theft behavior is realized. By using image recognition and object tracking technology, suspicious individuals in the anti-theft area can be accurately identified and tracked, improving the accuracy and efficiency of monitoring. By comparing and analyzing the moving track of the target object and the cable tension data, normal operation and theft behavior can be effectively distinguished, and the false alarm rate can be reduced. The timely response mechanism can quickly notify security personnel and intervene on site through sound and light alarm when confirming the occurrence of theft behavior. Not only the safety of the cable is improved, but also the stable operation of the power system is maintained, and the loss caused by cable theft is reduced. BRIEF DESCRIPTION OF DRAWINGS

[0032] In order to make the above objectives, features and advantages of the present application more apparent, the specific embodiments of the present application will be described in detail below with reference to the drawings. Obviously, the described embodiments are only some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without any creative effort should fall within the protection scope of the present application.

[0033] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced without the specific details, other than those described herein, and it is understood that the present application is not limited to the embodiments described herein and can be practiced with or without other apparatuses, systems, structures, methodologies, procedures, components, materials and so on. Therefore, the present application is not limited to the specific embodiments disclosed below, but includes any alterations, modifications, and improvements within the scope of the present application.

[0034] Embodiment 1

[0035] Reference Figure 1 For an embodiment of the present application, a cable anti-theft monitoring method is provided, which comprises:

[0036] An image of the anti-theft area is captured by a camera, and video information is obtained;

[0037] A key image is intercepted from the video information, and an object in the key image is analyzed to obtain displacement data to determine a moving track and a speed;

[0038] A tension of the cable is measured, and a change of the tension is detected by deformation of a resistance strain gauge;

[0039] The moving track and the speed of the target object are compared with the tension parameter of the cable in real time, and it is judged whether the data conforms to a preset theft behavior standard.

[0040] Acquiring video information involves deploying night vision cameras to automatically capture two frames of video per second; automatically adjusting the resolution and contrast of the captured video frames, and implementing noise reduction algorithms to ensure that the image quality meets the requirements of subsequent processing.

[0041] Analyzing objects in key images includes applying scene change detection algorithms, automatically extracting keyframes from the video stream, running the Faster R-CNN algorithm in each keyframe, and identifying and locating objects in the image.

[0042] The scene change detection algorithm is based on the amount of pixel change between image frames. When the change exceeds a set threshold, it is identified as a key frame. This threshold is set according to the environment and test data to ensure that only frames containing important events are selected.

[0043] The DeepSORT tracking algorithm is applied to the objects identified in the keyframes. The position coordinate sequence of each object is extracted from the tracking data provided by the DeepSORT algorithm. By calculating the changes in continuous coordinates, the movement trajectory and speed of the object are output.

[0044] Faster R-CNN can process data in real time and provide accurate object bounding boxes. DeepSORT can effectively track multiple objects in a video frame sequence, maintaining tracking continuity even when objects are occluded or temporarily leave the frame.

[0045] Faster R-CNN is used to identify and locate dynamic objects (potential thieves) in a video and to provide the bounding boxes of the objects.

[0046] Applying DeepSORT: Tracking a well-located object, extracting its movement trajectory, and using the output of Faster R-CNN to track the object, outputting a sequence of the object's position coordinates in the video sequence.

[0047] The object's movement speed and rate of change of speed are calculated. Based on the position coordinate sequence, the object's movement distance per frame is calculated to obtain the speed. The rate of change of speed is obtained by differencing and smoothing the speed sequence.

[0048] Detecting tensile force changes by measuring the deformation of resistance strain gauges involves installing strain gauges at critical stress points in the cable, connecting the strain gauges to a measuring circuit via wires. This circuit includes a signal amplifier and an analog-to-digital converter to ensure that the physical deformation signal is converted into a usable electronic signal. The installed strain gauges and measuring circuit are calibrated to ensure they accurately reflect tensile force changes under different loads. This typically involves applying a known load in a controlled environment, recording the strain gauge response, monitoring the cable tension in real time, recording the resistance change data from the strain gauges, and converting the resistance change into a tensile force parameter.

[0049] The key stress point is the middle section of the cable, which is most likely to exhibit significant deformation under external force.

[0050] Real-time comparison includes feature extraction of movement trajectory and speed data with cable tension parameter data, synchronizing movement trajectory and speed data with tension parameter data in time and unifying the format, extracting the average value, maximum value, and rate of change of movement speed from movement trajectory and speed data, and extracting the peak value and trend of tension from tension parameters;

[0051] The trend of change was obtained through linear regression analysis. The slope was used for quantification, with a positive slope indicating an increasing trend and a negative slope indicating a decreasing trend.

[0052] Linear regression analysis was used to quantify the changing trend. Data points within a certain time window were collected from the movement trajectory and speed monitoring system. Data within the same time window was collected. The timestamps of all data points were aligned, and data cleaning and preprocessing were performed. A linear regression model was established, applying linear regression analysis to the data points of tension parameters and movement trajectory. The timestamps of the data points were used as independent variables (X-axis), and the tension parameter or movement speed was used as the dependent variable (Y-axis). The linear regression model was trained, and the model parameters (slope and intercept) were obtained. The slope represents the rate of change of tension or movement speed over time; a positive slope indicates an increasing trend, and a negative slope indicates a decreasing trend.

[0053] Determining whether the data meets the preset theft behavior criteria involves constructing a cable anti-theft monitoring model from the data obtained through feature extraction, comparing the model output result Y with a preset threshold, and determining that theft has occurred if Y is greater than or equal to the preset threshold, and that no theft has occurred if Y is less than the preset threshold.

[0054] The cable theft monitoring model is represented as follows:

[0055]

[0056] Where Y represents the overall score. v represents the average speed at which an object moves. max F represents the maximum velocity of the object recorded within the measurement time window, Δv represents the rate of change of the object's velocity, and F represents the maximum velocity of the object within the measurement time window. max β represents the maximum tensile force recorded within the measurement time window. F The slope represents the trend of tensile force change, a, b, c, d, and e represent weighting coefficients, and tanh(·) represents the hyperbolic tangent function. This represents the natural logarithmic transformation of the average velocity, e c·Δv The sigmoid function, with base e, is an exponential function. F) represents an S-shaped logical function, abs(β) F ) represents the absolute value function.

[0057] If theft is detected, a data pop-up window for theft information is triggered and a text message is sent to staff. An alarm sound is broadcast in the security area and the lights are controlled to flash.

[0058] If it is determined that no theft has occurred, identity verification and behavioral analysis are performed on the personnel within the security area.

[0059] The identity verification and behavior analysis process includes automatically triggering the behavior pattern analysis module when the system's algorithm determines that no theft has occurred. This module collects the movement trajectory and behavior data of the person in question within the monitoring area, analyzes the data using an abnormal behavior detection algorithm, and analyzes whether the individual's behavior conforms to historically marked abnormal behavior patterns. This invention uses the isolated forest algorithm for analysis, outputting a score based on the trained isolated forest model. If the score exceeds a preset threshold, it is judged as an abnormal behavior pattern.

[0060] If the behavioral pattern analysis results show potential abnormal behavior, a biometric identification strategy is triggered. The deployed biometric identification technology (this invention deploys facial recognition and voiceprint recognition) is used to attempt to confirm the individual's identity. Biometric data is collected and matched with known templates in the database to verify whether the individual is an authorized person or a known suspect.

[0061] If biometrics cannot confirm an individual's identity, an interactive verification strategy is initiated. An audio question is uttered to the individual via a speaker, and the response is received and analyzed via a microphone. The content of the response is analyzed to determine whether the individual's response is reasonable or conforms to known security protocols, thereby further confirming the individual's intent.

[0062] While conducting interactive verification, environmental data is comprehensively analyzed, and environmental sensor data (temperature, light conditions) is monitored and analyzed in real time. Attention is paid to environmental changes that may be related to individual behavior. If an environmental change matching abnormal behavior is detected (a change in light is detected during a period when no one should be active), this information is combined with the aforementioned analysis results to conduct a final safety assessment.

[0063] Integrate all collected and analyzed data (behavioral patterns, biometrics, interactive responses, and environmental awareness) to build an ensemble model. The model accepts this data and assigns weights to different data sources based on historical data. These weights are determined by the contribution of each data type to identifying theft in historical cases. Each data type is converted into quantifiable features. Abnormal scores for behavioral patterns, matching probabilities for biometrics, consistency scores for interactive responses, and anomalous indicators for environmental awareness are converted into standardized scores. All features are normalized to ensure they are on the same order of magnitude, facilitating ensemble analysis. A decision tree is used to integrate various data types. Based on training data, the model automatically learns how to comprehensively assess potential security threats from various features. A decision threshold is set; when the comprehensive analysis result exceeds this threshold, a theft is identified, and a security alert is triggered.

[0064] Example 2

[0065] Reference Figure 2 According to one embodiment of the present invention, a cable anti-theft monitoring system is provided, including: a target object identification module, a tension sensor and an alarm module;

[0066] The target object recognition module captures images of the anti-theft area at preset time intervals using a camera, obtains video information of the anti-theft area, extracts images from it to obtain image information of the anti-theft area, identifies objects in the image information to obtain displacement data, and determines their movement trajectory.

[0067] The tension sensor acquires the tension parameter data of the cable. Under the action of external force, the elastic element of the tension sensor undergoes elastic deformation, causing the resistance strain gauge attached to its surface to deform as well. The resistance value changes with the deformation. The measuring circuit converts this resistance change into a measurable electrical signal, thereby acquiring the tension parameter data of the cable, and comparing the movement trajectory of the target object with the tension parameter value of the cable.

[0068] The alarm module compares the tensile parameter data and movement data with the standards used to judge theft. If the comparison results meet the standards for theft, the theft is confirmed. The alarm module will send a data pop-up or SMS containing theft information to the client to notify the staff in a timely manner. At the same time, it will broadcast alarm prompts and control the flashing lights in the anti-theft area to deter cable thieves.

[0079] This invention incorporates a high-resolution night vision camera, an integrated tension sensor, an advanced data processing unit, and an automated alarm system.

[0080] The traditional method involves installing a standard-resolution camera and a basic tension sensor, using a simple threshold to trigger the alarm system.
