However, these methods have problems such as high cost, large workload, and low efficiency. Especially in areas with complex terrain and extensive line distribution, the inspection work is more difficult. To solve these problems, global navigation satellite systems (GNSS), such as the Beidou satellite navigation system (BDS), have gradually been applied to the field of power inspection.

[0090] Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement them. In addition, for the sake of clarity, parts not related to the description of the exemplary embodiments are omitted in the accompanying drawings.

[0091] In the present disclosure, it should be understood that terms such as "include" or "have" are intended to indicate the presence of features, numbers, steps, behaviors, components, parts, or a combination thereof disclosed in the present specification, and are not intended to exclude the possibility that one or more other features, numbers, steps, behaviors, components, parts, or a combination thereof exist or are added.

[0092] It should also be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0093] As mentioned above, most existing technologies use a fixed displacement threshold. When the tower displacement measured by positioning technology exceeds the displacement threshold, it is considered that abnormal displacement occurs. However, existing technologies cannot automatically adapt to different environmental conditions or regional characteristics, resulting in common false alarms or missed alarms in certain complex geographical environments. In addition, although positioning technologies such as the Beidou system have high-precision positioning capabilities, in existing solutions, the positioning accuracy is reduced in remote areas or environments with large signal interference, making it difficult to ensure the reliability of abnormal detection.

[0094] In order to solve the above problems in the prior art, the disclosed embodiment provides an efficient, intelligent and adaptive regional pole tower position abnormality intelligent detection system, which adopts an artificial intelligence algorithm, based on the distance data between the multiple pole towers, and uses a trained deep neural network model based on the attention mechanism to calculate the probability of abnormal displacement, which does not rely on a fixed displacement threshold. By using the sample distance matrix and sample label vector of the multiple pole towers for model training, it can automatically adapt to the different environmental conditions or regional characteristics of the towers, and can especially improve the problem of false alarms or missed alarms in complex geographical environments. In addition, by using the distance between the multiple pole towers to generate a distance matrix for detection, in remote areas or environments with large signal interference, the systematic error of the location information can be effectively eliminated, and the reliability of abnormality detection can be improved.

[0095] Figure 1 A schematic structural diagram of a regional tower position abnormality intelligent detection system according to an embodiment of the present disclosure is shown.

[0096] Figure 2 A schematic diagram showing the use of a trained artificial intelligence model to calculate the probability of abnormal displacement of each of the plurality of towers according to an embodiment of the present disclosure.

[0097] like Figure 1 and Figure 2 As shown, the system includes multiple positioning terminals and monitoring equipment. The multiple positioning terminals are respectively arranged at designated positions of the multiple pole towers, and are used to obtain the position information of the corresponding pole towers and send the position information to the monitoring equipment. The position information includes the altitude and longitude and latitude coordinates of the positioning terminal.

[0098] According to an embodiment of the present disclosure, the positioning terminal uses Beidou differential positioning technology to obtain the location information of the corresponding tower. Beidou differential positioning technology is a high-precision positioning technology based on the Beidou satellite navigation system. It uses a base station receiver and a mobile receiver with a known position to simultaneously receive satellite signals, and eliminates errors by comparing the differences between the two. Specifically, the position of the base station receiver is known and can be corrected by actual measurement, while the position of the mobile receiver needs to be measured, and its error can be eliminated by comparing it with the base station receiver. Beidou differential positioning technology has high precision and can achieve centimeter-level positioning accuracy. It is suitable for occasions that require higher positioning accuracy, such as navigation and surveying and mapping with precise positioning. At the same time, Beidou differential positioning technology also has high stability. Based on the differential positioning method, it can stably provide more accurate and continuous location information, avoiding errors caused by uncontrollable factors such as signal interference and weather changes.

[0099] According to an embodiment of the present disclosure, the monitoring device is configured to: calculate the distance between each of the multiple towers based on the position information of the multiple towers; generate a distance matrix based on the distance between each of the multiple towers; and calculate the abnormal displacement probability of each of the multiple towers using a trained artificial intelligence model based on the distance matrix, wherein the artificial intelligence model is obtained by training a deep neural network model based on an attention mechanism using sample data generated according to the position information of the multiple towers, and the artificial intelligence model includes an attention layer and a deep neural network.

[0100] According to an embodiment of the present disclosure, the use of the trained artificial intelligence model to calculate the abnormal displacement probability of each of the multiple towers includes: inputting the distance matrix into the attention layer to obtain an attention-weighted distance matrix, wherein the attention-weighted distance matrix is ​​obtained by multiplying the distance matrix with normalized weights, and the normalized weights are obtained based on the distance matrix; inputting the attention-weighted distance matrix into the deep neural network to obtain the abnormal displacement probability of each tower.

[0101] Specifically, according to an embodiment of the present disclosure, the distance matrix is:

[0102]

[0103] Wherein, h is the distance matrix, N is the number of the plurality of towers, and h 11 is zero, h N1 h is the distance between the positioning terminal of the Nth tower and the positioning terminal of the first tower, 1N h is the distance between the positioning terminal of the first tower and the positioning terminal of the Nth tower, NN is zero.

[0104] According to an embodiment of the present disclosure, the inputting the distance matrix into the attention layer to obtain the attention weighted distance matrix includes: calculating Q = hW Q , K = hW K , W Q and W K is the weight of the attention layer; calculate the normalized weight Softmax (QK T ), where QK T To combine Q and K T Do the dot product; by adding h to Softmax(QK T ) performs dot multiplication to calculate the attention weighted distance matrix.

[0105] According to an embodiment of the present disclosure, the inputting the attention weighted distance matrix into the deep neural network to obtain the abnormal displacement probability of each tower includes: inputting the attention weighted distance matrix into the deep neural network to obtain an N-dimensional vector O=[O 1 ,O 2 ,…O n ,…,O N ], where O 1 ,O 2 ,O n ,O N They represent the probability of abnormal displacement of the 1st, 2nd, nth, and Nth towers respectively.

[0106] Each tower in the region has different environmental conditions (such as ground height, foundation stability, tower inclination, distance from other towers, density of nearby towers, vegetation type near towers, temperature, humidity, wind speed near towers, etc.) and positioning terminal signal quality, which have different impacts on the accuracy of the prediction results of the artificial intelligence model. These influencing factors are difficult to analyze qualitatively or quantitatively through mathematical modeling due to their large number and complex relationships. By introducing the attention weighting matrix into the artificial intelligence model and weighting the distance between towers, possible influencing factors can be automatically converted into weights of the artificial intelligence model through training, thereby obtaining more accurate prediction results.

[0107] According to an embodiment of the present disclosure, the deep neural network includes a three-layer convolutional neural network, the first layer includes 80 neurons, the second layer includes 120 neurons, and the third layer includes 100 neurons.

[0108] According to the embodiments of the present disclosure, <O n ≤1, when 0 <O n <0.5, it is considered that there is no abnormal displacement of the tower. n When ≤1, it is considered that the tower has abnormal displacement.

[0109] According to an embodiment of the present disclosure, the monitoring device includes an edge device arranged in the designated area. When the monitoring device finds a pole tower with abnormal displacement, the monitoring device reports the relevant information of the pole tower to a monitoring center server, and the monitoring center server is connected to monitoring devices in multiple designated areas; or, the monitoring device includes a monitoring center server, and the monitoring center server is connected to positioning terminals in multiple designated areas.

[0110] According to the embodiments of the present disclosure, by implementing the monitoring device as an edge device in a specified area, distributed detection of abnormal displacement of the tower can be achieved, reducing the load of the monitoring center server, and having higher detection efficiency and real-time performance.

[0111] According to an embodiment of the present disclosure, the monitoring device is also configured to: when the number or installation position of the multiple towers in the designated area changes, retrain the artificial intelligence model according to the new position information of the multiple towers.

[0112] The existing inspection process of power transmission line towers mainly uses GPS positioning as the main means, combined with drones, manual inspections and other means, and the main detection data is the settlement, displacement and other data of the towers themselves, ignoring the linkage changes between towers. These existing detection data are easy to deviate from the actual data in remote areas or environments with large signal interference, resulting in a decrease in positioning accuracy, making it difficult to ensure the reliability of abnormal detection, and unable to deeply analyze the trend of tower position changes or potential hidden dangers. The tower position abnormality detection system disclosed in the present invention calculates the distance between the multiple towers based on the position information of the multiple towers, and generates a distance matrix based on the distance between the multiple towers, which significantly improves the accuracy of power tower position monitoring and can detect small displacement changes. At the same time, the present invention introduces an artificial intelligence model that can automatically adapt to the different environmental conditions or regional characteristics of the towers, improving the reliability of abnormal detection and the efficiency of inspection.

[0113] According to an embodiment of the present disclosure, the positioning terminal can be arranged at the top of the tower. When the tower is displaced, the displacement at the top is usually greater than that at other positions of the tower body. Therefore, arranging the positioning terminal at the top of the tower helps to improve the sensitivity and accuracy of detection.

[0114] According to an embodiment of the present disclosure, the monitoring device is further configured to output an alarm message when the abnormal displacement probability of any tower indicates that the tower has abnormal displacement, or when the abnormal displacement probability of the tower continues to increase or abnormal fluctuation occurs.

[0115] The abnormal displacement detection of towers in the prior art can usually only give an alarm when abnormal displacement occurs, while the abnormal displacement detection system of the disclosed embodiment can detect hidden problems such as long-term slight tilt or gradual settlement of towers in advance according to the change in the probability of abnormal displacement of towers, thereby preventing problems before they occur, which is of great positive significance for effectively preventing power failures caused by tower collapse in severe weather such as rain, snow and frost.

[0116] According to an embodiment of the present disclosure, the monitoring device is also configured to train the artificial intelligence model, including: constructing a sample distance matrix based on normal position information of each of the multiple towers when it is in a normal position and abnormal position information when there is abnormal displacement, and constructing a sample label vector corresponding to the sample distance matrix based on whether each of the multiple towers has abnormal displacement; training the artificial intelligence model based on the sample distance matrix and the corresponding sample label vector.

[0117] According to an embodiment of the present disclosure, the normal position information includes: position information manually set according to the reference position information of the pole tower and the preset normal displacement condition, and / or position information acquired by the corresponding positioning terminal when the pole tower is actually found to be in the normal position; the abnormal position information includes: position information manually set according to the reference position information of the pole tower and the preset abnormal displacement condition, and / or position information acquired by the corresponding positioning terminal when the pole tower is actually found to have abnormal displacement.

[0118] According to an embodiment of the present disclosure, constructing a sample distance matrix based on normal position information when each of the multiple towers is in a normal position and abnormal position information when there is abnormal displacement, and constructing a sample label vector corresponding to the sample distance matrix based on whether each of the multiple towers has abnormal displacement, includes:

[0119] For each of the plurality of towers T n , obtain multiple normal position information NP when the tower is in multiple normal positions nj , 1≤j≤M1, M1 is the number of normal position information of the tower;

[0123] In a specific example, the reference position information of the pole tower may be the position information obtained by the corresponding positioning terminal when the pole tower is installed. The position information may be considered as the position information of the pole tower in a normal position state, and may be used as a reference for subsequent judgment of whether the pole tower has abnormal displacement. Normal displacement conditions may be preset based on experience, for example, when the position information of the pole tower changes by a certain amount relative to the reference position information, it may be considered as normal displacement.

[0124] In order to train the artificial intelligence model, a large amount of sample data is required. However, it is obviously unrealistic to artificially displace each tower in the area in order to obtain sample data. Therefore, some position information can be manually set according to the benchmark position information of the tower and the preset normal displacement conditions. The position information contains normal position information and abnormal position information, and the corresponding sample distance matrix and sample label vector are constructed based on the position information to train the artificial intelligence model.

[0125] Furthermore, in order to make the prediction results of the artificial intelligence model more in line with reality, the actual position information of the tower obtained daily and the labels of whether the tower has abnormal displacement can also be used as samples for model training to enhance the model's adaptability to the environment.
