As for the structures, products, etc. disclosed in the embodiments, since they correspond to the parts disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the description of the method part.

[0038] The embodiment of the present invention provides a distribution line insulation fixing device with a loosening detection function, such as Figure 1 As shown, it is a structural schematic diagram of a distribution line insulation fixing device with a loosening detection function provided by an embodiment of the present invention, Figure 1 The provided power distribution line insulation fixing device comprises a data processing module 101, a tension detection module 102, an image acquisition module 103, a temperature detection module 104 and a communication module 105 which are arranged on the structural body of the power distribution line insulation fixing device. The data processing module 101 is connected with the tension detection module 102, the image acquisition module 103, the temperature detection module 104 and the communication module 105, so that the data processing module 101 can realize data transmission with the tension detection module 102, the image acquisition module 103, the temperature detection module 104 and the communication module 105. In addition, a wire is also fixed on the structural body of the power distribution line insulation fixing device.

[0039] The tension detection module is used to periodically detect the tension data of the wire fixed to the structure body, and transmit the tension data to the data processing module.

[0040] In this embodiment, the tension detection module is used to periodically detect the tension data of the wire fixed by the structural body. The interval of each cycle can be set according to actual needs, for example, the interval of the cycle can be set to 24 hours or 48 hours, etc., which is not specifically limited in this embodiment. In addition, the tension detection module can be implemented by a tension sensor, and the type of the tension sensor can be a resistive strain tension sensor, a piezoresistive tension sensor, or a piezoelectric tension sensor. After the tension detection module detects the tension data periodically, it transmits the tension data to the data processing module.

[0041] The image acquisition module is used to periodically capture a first image in the direction where the structure body is located, and transmit the first image to the data processing module.

[0042] The image acquisition module is a module for performing image acquisition. For example, the image acquisition includes a camera, and the image acquisition module realizes image acquisition through the camera. In this embodiment, the shooting angle of the image acquisition module is toward the structural body, and the image acquisition module is used to periodically capture the first image in the direction of the structural body, wherein the interval of each period is the same as the interval of the tension detection module detecting the tension data, and the time when the image acquisition module captures the first image is the same as the time when the tension detection module collects the tension data. After the image acquisition module captures the first image in each period, the first image is transmitted to the data processing module, so that the data processing module can process the first image and the tension data at the same time.

[0043] The temperature detection module is used to collect temperature data in real time and transmit the temperature data to the data processing module.

[0044] In addition, the temperature detection module in this embodiment collects temperature data of the environment where the structure body is located in real time, and transmits the real-time collected temperature data to the data processing module.

[0045] The data processing module is used to determine the first loose coefficient based on the tension data and the temperature data; determine the second loose coefficient based on the first image; determine the degree of looseness based on the first loose coefficient and the second loose coefficient; and determine whether to generate maintenance information based on the degree of looseness, and when the maintenance information is generated, send the maintenance information to the communication module.

[0046] The data processing module is used to periodically receive the tension data sent by the tension detection module and the first image sent by the image acquisition module, and to receive the temperature data sent by the temperature detection module in real time. After receiving the tension data and the first image each time, the data processing module needs to determine the first loose coefficient according to the tension data and the temperature data. The reason for collecting temperature data in this embodiment is that since the wire is not located in a constant temperature environment, the change in temperature causes the wire to have thermal expansion and contraction, resulting in changes in the tension of the wire. Therefore, in this embodiment, it is necessary to collect temperature data to consider the influence of temperature on the tension of the wire, so as to eliminate the tension change caused by temperature in the subsequent analysis process. Exemplarily, when determining the first loose coefficient, the tension correction factor can be first determined according to the current temperature data, and the tension correction factor is used to correct the tension data to exclude the tension change caused by temperature. After that, the data processing module determines the corrected tension data according to the tension correction factor and the tension data, and then determines the first loose coefficient according to the corrected tension data, wherein the first loose coefficient is a coefficient used to characterize the degree of looseness of the wire, and the larger the first loose coefficient, the looser the wire.

[0047] When the data processing module determines the second loose coefficient, it is necessary to analyze the first image, determine the distance between the first reference point in the wire in the first image and the second reference point on the structural body, and determine the second loose data based on the distance. It is understandable that when the wire is subjected to tension, the wire will undergo certain deformation and displacement, which will cause the relative position between the wire and the structural body to change. Therefore, by analyzing the change in the relative position between the wire and the structural body through the first image, the looseness of the wire can also be reflected to obtain the second loose coefficient. Similarly, the second loose coefficient is a coefficient used to characterize the degree of looseness of the wire. The larger the second loose coefficient, the looser the wire.

[0048] After determining the first loose coefficient and the second loose coefficient, the data processing module can determine the degree of looseness of the wire according to the first loose coefficient and the second loose coefficient. In this embodiment, the higher the degree of looseness of the wire, the looser the wire is. In one embodiment, when determining the degree of looseness of the wire, the degree of looseness can be determined by taking the value after weighted summation of the first loose coefficient and the second loose coefficient, or the degree of looseness can be determined according to the sum of the first loose coefficient and the second loose coefficient. After determining the degree of looseness of the wire, the data processing module further determines whether it is necessary to overhaul the insulation fixing device of the distribution line according to the degree of looseness. If overhaul is required, overhaul information is generated and sent to the communication module.

[0049] The communication module is used to send maintenance information to the mobile terminal.

[0050] After receiving the maintenance information, the communication module sends the maintenance information to the mobile terminal. The maintenance personnel can check the maintenance information on the mobile terminal to know that the distribution line insulation fixing device needs maintenance, and then go to the site for maintenance. In one embodiment, the maintenance information also includes the location information of the distribution line insulation fixing device, so that the maintenance personnel can accurately determine the distribution line insulation fixing device that needs maintenance.

[0051] In addition, the embodiment of the present invention also provides a looseness detection method, such as Figure 2 As shown, it is a flow chart of the looseness detection method provided by an embodiment of the present invention. The looseness detection method can be executed by the data processing module of the distribution line insulation fixing device with looseness detection function. The looseness detection method includes:

[0052] Step 201: Receive temperature data sent by a temperature detection module in real time.

[0053] Step 202: Periodically receive the tension data sent by the tension detection module and the first image sent by the image acquisition module.

[0054] Step 203: Determine a first looseness coefficient according to the tension data and the temperature data.

[0055] Step 204: Determine a second looseness coefficient according to the first image.

[0056] Step 205: Determine the degree of looseness according to the first looseness coefficient and the second looseness coefficient.

[0057] Step 206: Determine whether to generate maintenance information according to the degree of looseness, and if the maintenance information is generated, send the maintenance information to the communication module, so as to send the maintenance information to the mobile terminal through the communication module.

[0058] As described above, the embodiment of the present invention provides a distribution line insulation fixing device with a looseness detection function, including a data processing module, a tension detection module, an image acquisition module, a temperature detection module and a communication module arranged on the structural body of the distribution line insulation fixing device. The tension detection module and the image acquisition module periodically transmit the tension data and the first image to the data processing module respectively, and the temperature detection module transmits the temperature data to the data processing module in real time. The data processing module is used to determine the first looseness coefficient according to the tension data and the temperature data; determine the second looseness coefficient according to the first image; determine the degree of looseness according to the first looseness coefficient and the second looseness coefficient; and determine whether to generate maintenance information according to the degree of looseness, and send the maintenance information to the mobile terminal through the communication module when the maintenance information is generated. The distribution line insulation fixing device provided by the embodiment of the present invention can detect the looseness of the wire, and inform the maintenance personnel by sending the maintenance information when the distribution line insulation fixing device needs to be repaired, without the need for the staff to go to the site to check the distribution line insulation fixing device one by one, while improving the maintenance efficiency of the distribution line insulation fixing device, it also saves a lot of manpower and time costs.

[0059] Based on the above embodiment, the data processing module is specifically used to obtain historical temperature data within a preset time length before receiving the tension data when receiving the tension data, and determine the tension correction factor based on the historical temperature data; determine the first loosening coefficient based on the tension correction factor and the tension data.

[0060] In this embodiment, the data processing module is specifically used to determine the moment when the tension data sent by the tension detection module is received, and obtain the historical temperature data within a preset time length before the moment. It can be understood that the temperature at a single moment cannot immediately cause the change of the heat of the wire to cause the wire to deform, and the heat of the wire accumulates or dissipates slowly. Therefore, in this embodiment, it is necessary to obtain the historical temperature data within a preset time length in history, wherein the preset time length can be set according to actual needs, for example, the preset time length can be 6 hours, etc., which is not specifically limited in this embodiment.

[0061] After obtaining the historical temperature data, the data processing module needs to further determine the tension correction factor according to the historical temperature data. In one embodiment, when determining the tension correction factor, the data processing module is specifically used to calculate the temperature average value of the historical temperature data, and determine the tension correction factor according to the temperature average value and the preset correction coefficient mapping relationship, wherein the correction coefficient mapping relationship includes tension correction factors corresponding to different temperature ranges. The user can measure the influence of different temperatures on the deformation of the wire in advance, and determine the change of the tension data of the wire caused by the deformation, so as to obtain the influence of different temperatures on the tension data of the wire and determine the corresponding tension correction factor, which is used to correct the tension data to eliminate the tension change caused by temperature. After that, the user can construct a correction coefficient mapping relationship according to the tension correction factors corresponding to different temperatures, for example, the correction coefficient mapping relationship can be recorded and saved in the form of a table. After calculating the temperature average value, the subsequent data processing module can determine the tension correction factor corresponding to the temperature average value by looking up the table.

[0062] Accordingly, the looseness detection method provided by the embodiment of the present invention further includes:

[0063] When the tension data is received, historical temperature data within a preset time length before the tension data is received is obtained, and a tension correction factor is determined according to the historical temperature data;

[0064] The first loosening coefficient is determined according to the tension correction factor and the tension data.

[0065] Based on the above embodiment, the data processing module is specifically used to determine the corrected tension data according to the tension correction factor and the tension data; determine the tension difference between the preset standard tension data and the corrected tension data, and determine the first loose coefficient according to the tension difference.

[0066] After determining the tension correction factor, the data processing module needs to further correct the tension data according to the tension correction factor to obtain the corrected tension data, which is the tension data that eliminates the influence of temperature on the tension. After obtaining the corrected tension data, the data processing module needs to further calculate the tension difference between the preset standard tension data and the corrected tension data, wherein the standard tension data can be pre-set, and the standard tension data is the tension data of the wire under the condition that the wire is not loose after the insulation fixing device of the distribution line fixes the wire in accordance with the operation standard. By calculating the tension difference between the standard tension data and the corrected tension data, it can be determined whether the wire is loose. It can be understood that the larger the tension difference, the looser the wire. After calculating the tension difference, the data processing module needs to further determine the first loose coefficient according to the tension difference. In this embodiment, the user can pre-set the loose coefficient corresponding to different tension difference ranges, and the data processing module determines the corresponding first loose coefficient according to the tension difference range where the tension difference is located.

[0067] Accordingly, the looseness detection method provided by the embodiment of the present invention further includes:

[0068] Determine the corrected tension data according to the tension correction factor and the tension data;

[0069] The tension difference between the preset standard tension data and the corrected tension data is determined, and the first looseness coefficient is determined according to the tension difference.

[0070] Based on the above embodiment, the data processing module is specifically used to determine, based on the first image, a first distance between a first reference point of the wire and a second reference point of the structural body, and compare the first distance with a standard distance, and determine a second looseness coefficient based on the comparison result. The standard distance is determined by taking an image of the wire when it is first fixed to the structural body.

[0071] In one embodiment, when determining the second looseness coefficient, the data processing module needs to identify the position of the structural body and the position of the wire fixed on the structural body from the first image. Specifically, the data processing module may first preprocess the first image, and the preprocessing process includes denoising and contrast enhancement, etc., so that the features of the structural body and the wire are more obvious. Afterwards, the edge detection algorithm (such as the Canny edge detector) is used to extract features from the first image to obtain edge information in the first image, and the edge information includes contour information of different objects. After obtaining the edge information, the shape features of each object in the first image are determined according to the edge information, and the structural body in the first image is identified and detected based on template matching or machine learning. Afterwards, on the basis of identifying the structural body, the wire fixed on the structural body is further identified, and the positions of the structural body and the wire are marked in the first image.

[0072] After determining the positions of the structural body and the wire, the first distance of the first reference point of the wire relative to the second reference point of the structural body can be further determined. Afterwards, the first distance is compared with the standard distance, wherein the standard distance is determined by shooting the image of the wire when it is first fixed to the structural body. It can be understood that when the wire is first fixed to the structural body and the installation process meets the operating standards, the wire can be fixed to the structural body more firmly, and the distance between the wire and the structural body is fixed. After the wire is loosened, the tension on the wire will change, causing the wire to have a certain displacement, and the relative position between the wire and the structural body will change at this time. Therefore, in this embodiment, the distance between the first reference point on the wire and the second reference point on the structural body can be determined according to the image when the wire is first fixed to the structural body, and the distance is used as the standard distance. For ease of identification, the user can mark the first reference point and the second reference point on the wire and the structural body respectively in advance. After obtaining the standard distance, the data processing module can compare the first distance determined according to the first reference point and the second reference point with the standard distance, and determine the second loose coefficient of the wire according to the comparison result. It is understandable that when the distance difference between the first distance and the standard distance is larger, the looseness of the wire is more serious and the second looseness coefficient is higher. In this embodiment, a mapping relationship between different distance differences and the second looseness coefficient can be preset, and the data processing module can determine the corresponding second looseness coefficient according to the mapping relationship.

[0073] Based on the above embodiment, the data processing module is specifically used to determine the first weight corresponding to the first loose coefficient and the second weight corresponding to the second loose coefficient, respectively, perform weighted summation of the first loose coefficient and the second loose coefficient according to the first weight and the second weight, obtain the target loose coefficient, and determine the degree of looseness according to the target loose coefficient.

[0074] In the present embodiment, since the tension change and displacement of the wire may cause the wire to loosen, considering that the tension is a key factor that directly affects the tightness of the wire, and although the displacement of the wire is related to the tension change, the displacement itself does not directly cause loosening, that is, the correlation between the tension change of the wire and the displacement of the wire and the loosening of the wire is different. Therefore, the data processing module of the present embodiment also needs to determine the first weight corresponding to the first loosening coefficient and the second weight corresponding to the second loosening coefficient respectively. Wherein the first weight and the second weight need to be artificially determined in advance, considering that there is a strong correlation between the tension change and the loosening of the wire, therefore, in the present embodiment, it is necessary to assign a higher value to the first weight, that is, the first weight is greater than the second weight. For example, the first weight can be set to 0.6, and the second weight can be set to 0.4. After determining the first weight and the second weight, the data processing module further performs weighted summation on the first loosening coefficient and the second loosening coefficient according to the first weight and the second weight, obtains the target loosening coefficient, and finally determines the degree of looseness according to the target loosening coefficient. In one embodiment, the user can pre-set the range of looseness coefficients corresponding to different degrees of looseness. After obtaining the target looseness coefficient, the data processing module determines the corresponding degree of looseness according to the range of looseness coefficients to which the target looseness coefficient belongs. It can be understood that the larger the target looseness coefficient, the looser the wire and the higher the degree of looseness.

[0075] Accordingly, the looseness detection method provided by the embodiment of the present invention further includes:

[0076] respectively determining a first weight corresponding to the first loose coefficient and a second weight corresponding to the second loose coefficient;

[0077] Performing weighted summation of the first looseness coefficient and the second looseness coefficient according to the first weight and the second weight to obtain a target looseness coefficient;

[0078] Determine the degree of loosening based on the target loosening factor.

[0079] On the basis of the above embodiment, the data processing module is specifically used to generate maintenance information when the looseness degree exceeds the looseness degree threshold.

[0080] After determining the degree of looseness, the data processing module needs to further determine whether the degree of looseness exceeds a looseness threshold, where the looseness threshold is the degree of looseness when the insulation fixing device of the distribution line needs to be repaired. If the degree of looseness exceeds the looseness threshold, the data processing module can generate maintenance information and send the maintenance information to the mobile terminal through the communication module. In one embodiment, the specific process of the data processing module sending the maintenance information is as follows: Figure 3 shown.

[0081] Accordingly, the looseness detection method provided by the embodiment of the present invention further includes:

[0082] When the looseness exceeds a looseness threshold, maintenance information is generated.

[0083] As mentioned above, the embodiment of the present invention provides a distribution line insulation fixing device with a looseness detection function, including a data processing module, a tension detection module, an image acquisition module, a temperature detection module and a communication module arranged on the structural body of the distribution line insulation fixing device, the tension detection module and the image acquisition module respectively periodically transmit the tension data and the first image to the data processing module, and the temperature detection module transmits the temperature data to the data processing module in real time, and the data processing module is used to determine the first looseness coefficient according to the tension data and the temperature data; determine the second looseness coefficient according to the first image; determine the degree of looseness according to the first looseness coefficient and the second looseness coefficient; and determine whether to generate maintenance information according to the degree of looseness, and send the maintenance information to the mobile terminal through the communication module when the maintenance information is generated. The distribution line insulation fixing device provided by the embodiment of the present invention can detect the looseness of the wire, and inform the maintenance personnel by sending the maintenance information when the distribution line insulation fixing device needs to be repaired, without the need for the staff to go to the site to check the distribution line insulation fixing device one by one, while improving the maintenance efficiency of the distribution line insulation fixing device, it also saves a lot of manpower cost and time cost. In addition, in the process of determining the first looseness coefficient, the embodiment of the present invention also takes into account the influence of temperature on the tension number of the wire. The tension data is corrected by determining the tension correction factor according to the temperature, so as to eliminate the tension changes caused by temperature in the subsequent analysis process, determine the ideal tension data of the wire, and further improve the accuracy of detecting the looseness of the wire.

[0084] The embodiment of the present invention also provides a looseness detection system, such as Figure 4 As shown, Figure 4 The present invention provides a schematic diagram of the structure of a loose detection system according to an embodiment of the present invention.
