[0030] This embodiment provides a method for determining the accuracy of cable data running on a mobile terminal, computer terminal, or similar computing device. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0031] Figure 2 This is a flowchart of a method for determining the accuracy of cable data according to an embodiment of this application. Figure 2 As shown, the method includes the following steps:

[0032] Step S201: Obtain cable data of the cables in the power well. The cable data includes at least a cable path diagram and an actual cable image. The cable path diagram is an image of the cable path in the power well obtained by the RTK positioning device, and the actual cable image is an image of the actual path of the cable in the power well.

[0033] Specifically, the RTK positioning equipment includes several repeaters to extend signal coverage and improve signal quality, a base station to receive positioning signals from satellites via a GPS receiver, and a mobile station to record positioning data. The cable path map is generated based on the positioning data recorded by the mobile station. Actual cable images of the cables in each power well during the laying process can be obtained using high-definition cameras or similar equipment.

[0034] Step S202: Compare the above cable path diagram with the actual cable image to obtain a first length ratio. The first length ratio is the ratio of the first overlapping length to the total path length in the actual cable image. The first overlapping length is the length of the overlapping portion between the actual cable image and the above cable path diagram.

[0035] Specifically, the cable path diagram is compared with the corresponding actual cable image to obtain the length of the overlapping part, namely the first overlapping length, and the proportion of the first overlapping length to the total length of the cable path in the actual cable image is obtained, which is denoted as the first length proportion.

[0036] Step S203: At least when the first length proportion is less than or equal to the first preset length proportion, it is preliminarily determined that the cable path diagram is inaccurate and the operating status does not meet the preset standard, and a first alarm message is issued. The first alarm message is used to indicate that the cable path diagram obtained by the RTK positioning device is inaccurate, and the operating status refers to the status of the operating parameters when the cable path diagram is obtained by the RTK positioning device.

[0037] Specifically, at least when the aforementioned first length proportion is less than or equal to the first preset length proportion, it is preliminarily determined that the cable path diagram is inaccurate and the operating condition does not meet the preset standard, and a first alarm message is issued. Conversely, when the aforementioned first length proportion is greater than the aforementioned first preset length proportion, it is preliminarily determined that the aforementioned cable path diagram is accurate and the aforementioned operating condition meets the preset standard.

[0038] In this embodiment, firstly, cable data of the cables in the power well is acquired. The cable data includes at least a cable path diagram and an actual cable image. The cable path diagram is an image of the cable path in the power well acquired by an RTK positioning device, and the actual cable image is an image of the actual path of the cable in the power well. Then, the cable path diagram and the actual cable image are compared to obtain a first length ratio. The first length ratio is the ratio of the first overlap length to the total path length in the actual cable image. The first overlap length is the length of the overlap portion between the actual cable image and the cable path diagram. Finally, if the first length ratio is less than or equal to a first preset length ratio, it is preliminarily determined that the cable path diagram is inaccurate and the operating status does not meet a preset standard, and a first alarm message is issued. The first alarm message is used to indicate that the cable path diagram acquired by the RTK positioning device is inaccurate, and the operating status refers to the status of the operating parameters when the cable path diagram was acquired by the RTK positioning device. This application detects the cable path map within a power well obtained through RTK positioning equipment and compares it with actual cable images within the well to determine the length ratio. If the length ratio is less than a preset ratio, it is preliminarily determined that the cable path map obtained by the RTK equipment is inaccurate. Based on this determination, the operating parameters of the RTK positioning equipment are adjusted to ensure that the accuracy of RTK positioning is effectively improved while simultaneously enhancing the safety of cable construction. This application solves the problem of low cable construction efficiency caused by the lack of accuracy determination of acquired cable data in existing technologies.

[0039] To enable those skilled in the art to better understand the technical solution of this application, the implementation process of the method for determining the accuracy of cable data in this application will be described in detail below with reference to specific embodiments.

[0040] To gain a clearer understanding of the cable's route and improve the efficiency of acquiring cable data, in an optional implementation, before step S202 above, the method further includes:

[0041] Step S301: Obtain the preset number of edge points of the cables in the power well using the RTK positioning device.

[0042] Step S302: Perform data fitting on all the above edge points to obtain the above cable path diagram.

[0043] In the above embodiment, a predetermined number of edge points of the cables within the power well to be detected are first determined. Data from all edge points is collected, including at least the cable's length, diameter, and material. This data is then processed and analyzed using statistical methods or mathematical modeling to fit the data, thereby determining the trends and patterns of each edge point and ultimately obtaining the cable path.

[0044] To improve data accuracy and provide a data foundation for subsequent data accuracy assessment, in one optional implementation, step S202 includes:

[0045] Step S2021: Extract edge features from the cable features in the actual cable image to obtain edge features;

[0046] Step S2022: Compare the aforementioned edge features with the aforementioned cable path diagram to obtain the aforementioned first overlap length;

[0047] Step S2023: Calculate the ratio of the first overlapping length to the total path length in the actual cable image to obtain the first length ratio.

[0048] In the above embodiments, cable feature extraction from cable images can typically be achieved using edge detection algorithms. Commonly used edge detection algorithms include the Sobel operator, the Prewitt operator, and Canny edge detection. After extracting the edge features, the edge features are compared with the cable path in the cable path diagram to obtain the length of the overlapping portion, i.e., the first overlapping length. Then, the proportion of the first overlapping length in the total path length in the actual cable image is calculated to obtain the first length proportion.

[0049] To effectively improve the accuracy of the acquired information, in an optional implementation, after step S203 above, the method further includes:

[0050] Step S401, the acquisition step, acquire the historical temperature and the current temperature, wherein the historical temperature is the temperature corresponding to each historical length ratio in the historical data, and the current temperature is the temperature corresponding to the first length ratio obtained at the moment.

[0051] Step S402, generation step, generating a temperature-length ratio curve based on the current length ratio, historical length ratio, current temperature and historical temperature. The temperature-length ratio curve is used to represent the relationship between temperature and the first length ratio.

[0052] Step S403, Calculation step: Calculate the derivative at the current temperature based on the temperature-length-gravity curve mentioned above;

[0053] Step S404, first execution step, if the derivative is less than or equal to the preset derivative, execute the first processing method, the first processing method is to increase the number of sampling points between the power wells to the first preset number;

[0054] Step S405, the second execution step, in the case that the derivative is greater than the preset derivative, execute the second processing method, which is to increase the number of repeaters to a second preset number.

[0055] In the above embodiments, the corresponding processing method is determined according to the change in the length ratio. When the derivative is greater than the preset derivative, the length ratio is slowly increased. At this time, the data collected at the cable construction site becomes more accurate, and the number of repeaters is adjusted to improve the accuracy of signal transmission. When the derivative is less than or equal to the preset derivative, the length ratio is decreased. In this case, the accuracy of the collected data fluctuates due to environmental factors. At this time, the number of sampling points between each power well is adjusted, which effectively improves the accuracy of the acquired information and the efficiency of cable construction.

[0056] Specifically, when the derivative is greater than the preset derivative, the temperature sensor installed in the construction area is controlled to acquire the temperature of the construction area. A temperature-length-weight curve is plotted based on the historical data of each length proportion and the temperature corresponding to the acquisition of the length proportion. The processing method for the RTK positioning device is determined based on the derivative of the temperature-length-weight curve at the current temperature. This includes the first processing method and the second processing method. The first processing method includes a first quantity adjustment method, a second quantity adjustment method, and a third quantity adjustment method. The first quantity adjustment method involves adjusting the number of repeaters to a first quantity when the derivative difference is less than or equal to a first preset derivative difference. The first quantity is the sum of the first preset quantity adjustment coefficient and the current preset value. The product of the number of repeaters, where the derivative difference is the difference between the derivative and the preset derivative, and the current number of devices is the current number of repeaters; the second quantity adjustment method is to adjust the number of repeaters to a second quantity when the derivative difference is greater than the first preset derivative difference and less than or equal to the second preset derivative difference, where the second quantity is the product of the second preset quantity adjustment coefficient and the current number of devices, and the first preset derivative difference is less than the second preset derivative difference; the third quantity adjustment method is to adjust the number of repeaters to a third quantity when the derivative difference is greater than the second preset derivative difference, where the third quantity is the product of the third preset quantity adjustment coefficient and the current number of devices.

[0057] When the aforementioned derivative is less than or equal to a preset derivative, the second processing method includes a first sampling adjustment method, a second sampling adjustment method, and a third sampling adjustment method. The first sampling method involves adjusting the number of sampling points between each power well to a first sampling number when the weight difference is less than or equal to a first preset weight difference. The weight difference is the difference between the length weight and a preset length weight. The first sampling number is the product of a first preset sampling adjustment coefficient and the current number of sampling points. The current sampling point is the number of sampling points within the current power well. The second sampling method involves adjusting the number of sampling points between each power well to a second sampling number when the weight difference is greater than the first preset weight difference and less than or equal to a second preset weight difference. The second sampling number is the product of a second preset sampling adjustment coefficient and the current number of sampling points. The third sampling method involves adjusting the number of sampling points between each power well to a third sampling number when the weight difference is greater than the second preset weight difference. The third sampling number is the product of a third preset sampling adjustment coefficient and the current number of sampling points. The above number of sampling points refers to the number of sampling points set by the RTK positioning device between each power well when acquiring the cable path between each power well.

[0058] To mitigate the issues of low data accuracy caused by complex terrain and insufficient sampling points, in an optional implementation, after step S203, the method further includes:

[0059] Step S501: Obtain the distance variance, which is the variance of the straight-line distance between each reference area, and the reference area is the area where the cable image and the cable path diagram do not overlap.

[0060] Step S502: If the distance variance is less than or equal to the preset distance variance, execute the third processing method and issue a second alarm message. The second alarm message is used to prompt the re-acquisition of the cable path diagram. The third processing method is to increase the number of edge points detected by the RTK positioning device to a third preset number.

[0061] Step S503: If the distance variance is greater than the preset distance variance, obtain the reference length, and make a final judgment on whether the cable path diagram is accurate and whether the operating condition meets the preset standard based on the reference length. The reference length is the sum of the side lengths of each of the reference areas.

[0062] In the above embodiments, if it is initially determined that the operating status of the RTK positioning device does not meet the preset standard and the cable path map is inaccurate, it is necessary to further re-determine whether the operating status of the RTK positioning device meets the preset standard based on the variance of the straight-line distance between each of the above reference areas. If the variance of the distance is greater than the preset distance variance, it is also necessary to further determine whether the cable path map is accurate and whether the operating status meets the preset standard. When the variance of the distance is less than or equal to the preset distance variance, it indicates that there are only a few continuous reference areas in this case. At this time, considering that the preset sampling points for the cable are too low, resulting in a deviation between the cable path map and the actual cable image, an alarm message is issued to re-acquire the cable path map of the cable in a single power well using the RTK positioning device, so as to provide timely warning of abnormal situations in cable construction, thereby improving the safety of cable construction while ensuring the accuracy of cable positioning. Specifically, when the aforementioned distance variance is less than or equal to a preset distance variance, a detection adjustment method for the number of sampling points is determined based on the variance difference value. The variance difference value is the difference between the aforementioned distance variance and the preset distance variance. The detection adjustment method includes a first detection adjustment method, a second detection adjustment method, and a third detection adjustment method. The first detection adjustment method involves adjusting the preset detection number of edge points detected by the RTK positioning device to a first detection number when the aforementioned variance difference value is less than or equal to a first preset variance difference value. The first detection number is the product of a first preset detection adjustment coefficient and a current preset detection number, where the current preset detection number is the number of edge points currently being detected. The second detection adjustment method involves adjusting the preset detection quantity of edge points within each power well to a second detection quantity when the variance difference is greater than the first preset variance difference and less than or equal to the second preset variance difference. The second detection quantity is the product of the second preset detection adjustment coefficient and the current preset detection quantity. The third detection adjustment method involves adjusting the preset detection quantity of edge points within each power well to a third detection quantity when the variance difference is greater than the second preset variance difference. The third detection quantity is the product of the third preset detection adjustment coefficient and the current preset detection quantity. The third set quantity can be the first detection quantity, the second detection quantity, or the third detection quantity. When the distance variance is greater than a preset distance variance, a final determination is made based on the reference length to assess the accuracy of the cable path diagram and whether the operating conditions meet the preset standards.

[0063] To effectively ensure the stable operation of the RTK positioning device, in an optional embodiment, after step S502, the method further includes:

[0064] Step S601: Obtain the latest cable path diagram. The latest cable path diagram is the cable path diagram that was re-obtained after the second alarm information was issued.

[0065] Step S602: Compare the latest cable path diagram with the historical cable path diagram to obtain the second length ratio. The historical cable path diagram is the cable path diagram obtained at a historical time. The second length ratio is the ratio of the second overlap length to the total path length in the latest cable path diagram. The second overlap length is the length of the overlap between the latest cable path diagram and the historical cable path diagram.

[0066] Step S602: If the second length proportion is greater than the second preset length proportion, it is determined that the cable path diagram is accurate and the operating condition meets the preset standard.

[0067] Step S603: If the second length ratio is less than or equal to the second preset length ratio, the above-mentioned acquisition step, generation step and calculation step are executed sequentially until the execution of the first execution step or the second execution step is completed.

[0068] In the above embodiment, the operating status of the RTK positioning device is determined to meet the preset standard based on the length proportion of the re-acquired cable path map, i.e., the second length proportion. The cable path map for a single power well in the historical record is compared with the re-acquired cable path map to obtain the proportion of the overlapping length to the total length of the re-acquired cable path, i.e., the second length proportion. If the second length proportion is less than or equal to the second preset length proportion, the deviation between the two cable path map acquisitions is large, and the RTK positioning device is unstable. Therefore, the processing method for the RTK positioning device is determined based on the derivative of the temperature-length proportion curve at the current temperature. The above acquisition step, generation step, and calculation step are executed sequentially. After calculating the derivative, it is compared with the preset derivative to determine whether to execute the first or second execution step. If the second length proportion is greater than the second preset length proportion, the deviation is small, and the RTK positioning device operates stably. The operating status of the RTK positioning device is determined to meet the preset standard, and the RTK positioning device is controlled to continue using the current operating parameters to acquire each cable path map.

[0069] To improve the accuracy of signal transmission, in one optional embodiment, step S503 includes:

[0070] Step S301: If the reference length is less than or equal to the preset length, it is finally determined that the cable path diagram is accurate and the operating condition meets the preset standard.

[0071] In step S302, if the reference length is greater than the preset length, it is finally determined that the cable path diagram is inaccurate and the operating status does not meet the preset standard, and the fourth processing method is executed, which is to increase the number of repeaters to the fourth preset number.

[0072] In the above embodiments, when the distance variance is greater than the preset distance variance, there is a problem of uneven dispersion of the reference area. In this case, due to the complex terrain, the drawing of the cable path map within the power well has multiple area deviations. At this time, the length sum of each reference area in the cable path map that does not coincide with the actual cable path map is obtained to determine the actual degree of deviation. When the length sum is less than or equal to the preset length sum, it is determined that the operation status of the RTK positioning device meets the preset standard. When the length sum is greater than the preset length sum, the actual degree of deviation is too large, and the number of repeaters is increased to improve the accuracy of signal transmission. Specifically, the device adjustment method for determining the number of repeaters is based on the length difference, where the length difference is the difference between the sum of the lengths and the preset length sum. The device adjustment method includes a first device adjustment method, a second device adjustment method, and a third device adjustment method. The first device adjustment method involves adjusting the number of repeaters to a corresponding first device number when the length difference is less than or equal to a first preset length difference. The first device number is the product of a first preset device adjustment coefficient and the current device number, where the current device number is the current number of repeaters. The second device adjustment method involves adjusting the number of repeaters to a corresponding first device number when the length difference is less than or equal to a second preset length difference. If the length difference is greater than the first preset length difference, the number of repeaters is adjusted to the second number of devices, where the second number of devices is the product of the second preset device adjustment coefficient and the current number of devices. The first preset length difference is less than the second preset length difference. The third device adjustment method is to adjust the number of repeaters to the third number of devices if the length difference is greater than the second preset length difference. The third number of devices is the product of the third preset device adjustment coefficient and the current number of devices. The fourth set number can be the first number of devices, the second number of devices, or the third number of devices. In addition, after adjusting the number of repeaters, the adjusted number is compared with the preset maximum number. If the adjusted number is less than or equal to the preset maximum number, the adjusted number is used as the operating parameter of the RTK positioning device. If the adjusted number is greater than the preset maximum number, the preset maximum number is used as the operating parameter of the RTK positioning device, and the number of sampling points between each power well is adjusted to the first sampling number. The weight difference is the difference between the length weight and the preset length weight. The first sampling number is the product of the first preset sampling adjustment coefficient and the current number of sampling points. The current sampling point is the number of sampling points in the current power well.

[0073] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.

[0074] This application also provides a device for determining the accuracy of cable data. It should be noted that this device can be used to execute the method for determining cable data accuracy provided in this application. This device is used to implement the above embodiments and preferred embodiments; details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that performs a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0075] The following describes the device for determining the accuracy of cable data provided in the embodiments of this application.

[0076] Figure 3 This is a structural block diagram of a device for determining the accuracy of cable data according to an embodiment of this application. Figure 3 As shown, the device includes:

[0077] The first acquisition unit 10 is used to acquire cable data of cables in the power well. The cable data includes at least a cable path diagram and an actual cable image. The cable path diagram is an image of the cable path in the power well acquired by an RTK positioning device, and the actual cable image is an image of the actual path of the cable in the power well.

[0078] Specifically, the RTK positioning equipment includes several repeaters to extend signal coverage and improve signal quality, a base station to receive positioning signals from satellites via a GPS receiver, and a mobile station to record positioning data. The cable path map is generated based on the positioning data recorded by the mobile station. Actual cable images of the cables in each power well during the laying process can be obtained using high-definition cameras or similar equipment.

[0079] The first comparison unit 20 is used to compare the cable path diagram with the actual cable image to obtain a first length ratio. The first length ratio is the ratio of the first overlap length to the total path length in the actual cable image. The first overlap length is the length of the overlap portion between the actual cable image and the cable path diagram.

[0080] Specifically, the cable path diagram is compared with the corresponding actual cable image to obtain the length of the overlapping part, namely the first overlapping length, and the proportion of the first overlapping length to the total length of the cable path in the actual cable image is obtained, which is denoted as the first length proportion.

[0081] The first determination unit 30 is used to preliminarily determine that the cable path diagram is inaccurate and the operating status does not meet the preset standard, at least when the first length proportion is less than or equal to the first preset length proportion, and to issue a first alarm message. The first alarm message is used to indicate that the cable path diagram obtained by the RTK positioning device is inaccurate, and the operating status refers to the status of the operating parameters when the cable path diagram is obtained by the RTK positioning device.

[0082] Specifically, at least when the aforementioned first length proportion is less than or equal to the first preset length proportion, it is preliminarily determined that the cable path diagram is inaccurate and the operating condition does not meet the preset standard, and a first alarm message is issued. Conversely, when the aforementioned first length proportion is greater than the aforementioned first preset length proportion, it is preliminarily determined that the aforementioned cable path diagram is accurate and the aforementioned operating condition meets the preset standard.

[0083] In this embodiment, the first acquisition unit is used to acquire cable data of the cable in the power well. The cable data includes at least a cable path diagram and an actual cable image. The cable path diagram is an image of the cable path in the power well acquired by the RTK positioning device, and the actual cable image is an image of the actual path of the cable in the power well. The first comparison unit is used to compare the cable path diagram and the actual cable image to obtain a length ratio. The length ratio is the ratio of the first overlap length to the total path length in the actual cable image. The first overlap length is the length of the overlap portion between the actual cable image and the cable path diagram. The first determination unit is used to initially determine that the cable path diagram is inaccurate and the operating status does not meet a preset standard, at least when the length ratio is less than or equal to the first preset length ratio, and to issue a first alarm message. The first alarm message is used to indicate that the cable path diagram acquired by the RTK positioning device is inaccurate, and the operating status refers to the status of the operating parameters when the cable path diagram was acquired by the RTK positioning device. This application detects the cable path map within a power well obtained through RTK positioning equipment and compares it with actual cable images within the well to determine the length ratio. If the length ratio is less than a preset ratio, it is preliminarily determined that the cable path map obtained by the RTK equipment is inaccurate. Based on this determination, the operating parameters of the RTK positioning equipment are adjusted to ensure that the accuracy of RTK positioning is effectively improved while simultaneously enhancing the safety of cable construction. This application solves the problem of low cable construction efficiency caused by the lack of accuracy determination of acquired cable data in existing technologies.

[0084] To provide a clearer understanding of the cable's route and improve the efficiency of acquiring cable data, in one optional embodiment, the device further includes:

[0085] The second acquisition unit is used to acquire a preset number of edge points of the cable in the power well through the RTK positioning device before comparing the above-mentioned cable path diagram with the actual cable image to obtain the first length ratio value.

[0086] The fitting unit is used to fit the data to all the above edge points to obtain the above cable path diagram.

[0087] In the above embodiment, a predetermined number of edge points of the cables within the power well to be detected are first determined. Data from all edge points is collected, including at least the cable's length, diameter, and material. This data is then processed and analyzed using statistical methods or mathematical modeling to fit the data, thereby determining the trends and patterns of each edge point and ultimately obtaining the cable path.

[0088] To improve data accuracy and provide a data foundation for subsequent data accuracy judgment, in one optional implementation, the first comparison unit includes:

[0089] The feature extraction module extracts edge features from the cable features in the actual cable image to obtain edge features;

[0090] The comparison module compares the aforementioned edge features with the aforementioned cable path diagram to obtain the aforementioned first overlap length;

[0091] The calculation module calculates the ratio of the first overlapping length to the total path length in the actual cable image to obtain the first length ratio.

[0092] In the above embodiments, cable feature extraction from cable images can typically be achieved using edge detection algorithms. Commonly used edge detection algorithms include the Sobel operator, the Prewitt operator, and Canny edge detection. After extracting the edge features, the edge features are compared with the cable path in the cable path diagram to obtain the length of the overlapping portion, i.e., the first overlapping length. Then, the proportion of the first overlapping length in the total path length in the actual cable image is calculated to obtain the first length proportion.

[0093] To effectively improve the accuracy of the acquired information, in one optional embodiment, the device further includes:

[0094] The third acquisition unit is used to perform an acquisition step after initially determining that the cable path diagram is inaccurate and the operating condition does not meet the preset standard, at least when the first length ratio is less than or equal to the first preset length ratio. The acquisition unit acquires the historical temperature and the current temperature. The historical temperature is the temperature corresponding to each historical length ratio in the historical data, and the current temperature is the temperature corresponding to the first length ratio obtained at the moment.

[0095] The generation unit is used to perform the generation step, generating a temperature-length ratio curve based on the current length ratio, historical length ratio, current temperature, and historical temperature. The temperature-length ratio curve is used to represent the relationship between temperature and the first length ratio.

[0096] The calculation unit is used to perform calculation steps and calculate the derivative at the current temperature based on the temperature-length-gravity curve mentioned above.

[0097] The first execution unit is used to execute the first execution step. When the derivative is less than or equal to the preset derivative, the first processing method is to increase the number of sampling points between the power wells to a first set number.

[0098] The second execution unit is used to execute the second execution step. When the derivative is greater than the preset derivative, the second processing method is to increase the number of repeaters to a second preset number.

[0099] In the above embodiments, the corresponding processing method is determined according to the change in the length ratio. When the derivative is greater than the preset derivative, the length ratio is slowly increased. At this time, the data collected at the cable construction site becomes more accurate, and the number of repeaters is adjusted to improve the accuracy of signal transmission. When the derivative is less than or equal to the preset derivative, the length ratio is decreased. In this case, the accuracy of the collected data fluctuates due to environmental factors. At this time, the number of sampling points between each power well is adjusted, which effectively improves the accuracy of the acquired information and the efficiency of cable construction.

[0100] Specifically, when the derivative is greater than the preset derivative, the temperature sensor installed in the construction area is controlled to acquire the temperature of the construction area. A temperature-length-weight curve is plotted based on the historical data of each length proportion and the temperature corresponding to the acquisition of the length proportion. The processing method for the RTK positioning device is determined based on the derivative of the temperature-length-weight curve at the current temperature. This includes the first processing method and the second processing method. The first processing method includes a first quantity adjustment method, a second quantity adjustment method, and a third quantity adjustment method. The first quantity adjustment method involves adjusting the number of repeaters to a first quantity when the derivative difference is less than or equal to a first preset derivative difference. The first quantity is the sum of the first preset quantity adjustment coefficient and the current preset value. The product of the number of repeaters, where the derivative difference is the difference between the derivative and the preset derivative, and the current number of devices is the current number of repeaters; the second quantity adjustment method is to adjust the number of repeaters to a second quantity when the derivative difference is greater than the first preset derivative difference and less than or equal to the second preset derivative difference, where the second quantity is the product of the second preset quantity adjustment coefficient and the current number of devices, and the first preset derivative difference is less than the second preset derivative difference; the third quantity adjustment method is to adjust the number of repeaters to a third quantity when the derivative difference is greater than the second preset derivative difference, where the third quantity is the product of the third preset quantity adjustment coefficient and the current number of devices. When the aforementioned derivative is less than or equal to a preset derivative, the second processing method includes a first sampling adjustment method, a second sampling adjustment method, and a third sampling adjustment method. The first sampling method involves adjusting the number of sampling points between each power well to a first sampling number when the weight difference is less than or equal to a first preset weight difference. The weight difference is the difference between the length weight and a preset length weight. The first sampling number is the product of a first preset sampling adjustment coefficient and the current number of sampling points. The current sampling point is the number of sampling points within the current power well. The second sampling method involves adjusting the number of sampling points between each power well to a second sampling number when the weight difference is greater than the first preset weight difference and less than or equal to a second preset weight difference. The second sampling number is the product of a second preset sampling adjustment coefficient and the current number of sampling points. The third sampling method involves adjusting the number of sampling points between each power well to a third sampling number when the weight difference is greater than the second preset weight difference. The third sampling number is the product of a third preset sampling adjustment coefficient and the current number of sampling points. The above number of sampling points refers to the number of sampling points set by the RTK positioning device between each power well when acquiring the cable path between each power well.

[0101] To mitigate the issues of low data accuracy caused by complex terrain and insufficient sampling points, in one optional embodiment, the above-mentioned apparatus further includes:

[0102] The fourth acquisition unit is used to acquire the distance variance after initially determining that the cable path diagram is inaccurate and the operating condition does not meet the preset standard when at least the first length ratio is less than or equal to the first preset length ratio. The distance variance is the variance of the straight distance between each reference area, and the reference area is the area where the cable image and the cable path diagram do not overlap.

[0103] The third execution unit is used to execute the third processing method and issue a second alarm message when the distance variance is less than or equal to the preset distance variance. The second alarm message is used to prompt the reacquisition of the cable path diagram. The third processing method is to increase the number of edge points detected by the RTK positioning device to a third preset number.

[0104] The second determination unit is used to obtain a reference length when the aforementioned distance variance is greater than a preset distance variance, and to make a final determination on whether the aforementioned cable path diagram is accurate and whether the aforementioned operating conditions meet the aforementioned preset standards based on the aforementioned reference length. The aforementioned reference length is the sum of the side lengths of each of the aforementioned reference areas.

[0105] In the above embodiments, if it is initially determined that the operating status of the RTK positioning device does not meet the preset standard and the cable path map is inaccurate, it is necessary to further re-determine whether the operating status of the RTK positioning device meets the preset standard based on the variance of the straight-line distance between each of the above reference areas. If the variance of the distance is greater than the preset distance variance, it is also necessary to further determine whether the cable path map is accurate and whether the operating status meets the preset standard. When the variance of the distance is less than or equal to the preset distance variance, it indicates that there are only a few continuous reference areas in this case. At this time, considering that the preset sampling points for the cable are too low, resulting in a deviation between the cable path map and the actual cable image, an alarm message is issued to re-acquire the cable path map of the cable in a single power well using the RTK positioning device, so as to provide timely warning of abnormal situations in cable construction, thereby improving the safety of cable construction while ensuring the accuracy of cable positioning. Specifically, when the aforementioned distance variance is less than or equal to a preset distance variance, a detection adjustment method for the number of sampling points is determined based on the variance difference value. The variance difference value is the difference between the aforementioned distance variance and the aforementioned preset distance variance. The detection adjustment method includes a first detection adjustment method, a second detection adjustment method, and a third detection adjustment method. The first detection adjustment method involves adjusting the preset detection number of edge points during RTK positioning device detection to a first detection number when the aforementioned variance difference value is less than or equal to a first preset variance difference value. The first detection number is the product of a first preset detection adjustment coefficient and a current preset detection number. The current preset detection number is... The number of edge points currently being detected; the second detection adjustment method is to adjust the preset detection number of edge points in each power well to the second detection number when the variance difference is greater than the first preset variance difference and less than or equal to the second preset variance difference, wherein the second detection number is the product of the second preset detection adjustment coefficient and the current preset detection number; the third detection adjustment method is to adjust the preset detection number of edge points in each power well to the third detection number when the variance difference is greater than the second preset variance difference, wherein the third detection number is the product of the third preset detection adjustment coefficient and the current preset detection number. When the distance variance is greater than the preset distance variance, a final determination is made based on the reference length to determine whether the cable path diagram is accurate and whether the operating condition meets the preset standards.

[0106] To effectively ensure the stable operation of the RTK positioning device, in one optional embodiment, the above-mentioned device further includes:

[0107] The fifth acquisition unit is used to acquire the latest cable path diagram after executing the third processing method and issuing the second alarm information when the distance variance is less than or equal to the preset distance variance. The latest cable path diagram is the cable path diagram re-acquired after issuing the second alarm information.

[0108] The second comparison unit is used to compare the latest cable path diagram with the historical cable path diagram to obtain a second length ratio. The historical cable path diagram is the cable path diagram obtained at a historical time. The second length ratio is the ratio of the second overlap length to the total path length in the latest cable path diagram. The second overlap length is the length of the overlap between the latest cable path diagram and the historical cable path diagram.

[0109] The third determination unit is used to determine that the cable path diagram is accurate and the operating condition meets the preset standard when the second length proportion is greater than the second preset length proportion.

[0110] The fourth execution unit, when the second length proportion is less than or equal to the second preset length proportion, sequentially executes the acquisition step, the generation step, and the calculation step until the execution of the first execution step or the second execution step is completed.

[0111] In the above embodiment, the operating status of the RTK positioning device is determined to meet the preset standard based on the length proportion of the re-acquired cable path map, i.e., the second length proportion. The cable path map for a single power well in the historical record is compared with the re-acquired cable path map to obtain the proportion of the overlapping length to the total length of the re-acquired cable path, i.e., the second length proportion. If the second length proportion is less than or equal to the second preset length proportion, the deviation between the two cable path map acquisitions is large, and the RTK positioning device is unstable. Therefore, the processing method for the RTK positioning device is determined based on the derivative of the temperature-length proportion curve at the current temperature. The above acquisition step, generation step, and calculation step are executed sequentially. After calculating the derivative, it is compared with the preset derivative to determine whether to execute the first or second execution step. If the second length proportion is greater than the second preset length proportion, the deviation is small, and the RTK positioning device operates stably. The operating status of the RTK positioning device is determined to meet the preset standard, and the RTK positioning device is controlled to continue using the current operating parameters to acquire each cable path map.

[0112] To improve the accuracy of signal transmission, in one optional embodiment, the second determination unit includes:

[0113] The first determination module, when the reference length is less than or equal to the preset length, finally determines that the cable path diagram is accurate and the operating condition meets the preset standard.

[0114] The second determination module, when the reference length is greater than the preset length, ultimately determines that the cable path diagram is inaccurate and the operating status does not meet the preset standard, and executes the fourth processing method, which is to increase the number of repeaters to the fourth preset number.

[0115] In the above embodiments, when the distance variance is greater than the preset distance variance, there is a problem of uneven dispersion of the reference area. In this case, due to the complex terrain, the drawing of the cable path map within the power well has multiple area deviations. At this time, the length sum of each reference area in the cable path map that does not coincide with the actual cable path map is obtained to determine the actual degree of deviation. When the length sum is less than or equal to the preset length sum, it is determined that the operation status of the RTK positioning device meets the preset standard. When the length sum is greater than the preset length sum, the actual degree of deviation is too large, and the number of repeaters is increased to improve the accuracy of signal transmission. Specifically, the device adjustment method for determining the number of repeaters is based on the length difference, where the length difference is the difference between the sum of the lengths and the preset sum of lengths. The device adjustment method includes a first device adjustment method, a second device adjustment method, and a third device adjustment method. The first device adjustment method involves adjusting the number of repeaters to a corresponding first device number when the length difference is less than or equal to a first preset length difference. The first device number is the product of a first preset device adjustment coefficient and the current device number, where the current device number is the current number of repeaters. The second device adjustment method involves adjusting the number of repeaters to a second device number when the length difference is less than or equal to a second preset length difference and the length difference is greater than the first preset length difference. The second device number is the product of a second preset device adjustment coefficient and the current device number, where the first preset length difference is less than the second preset length difference. The third device adjustment method involves adjusting the number of repeaters to a third device number when the length difference is greater than the second preset length difference. The third device number is the product of a third preset device adjustment coefficient and the current device number. In addition, after adjusting the number of repeaters, the adjusted number is compared with the preset maximum number. If the adjusted number is less than or equal to the preset maximum number, the adjusted number is used as the operating parameter of the RTK positioning device. If the adjusted number is greater than the preset maximum number, the preset maximum number is used as the operating parameter of the RTK positioning device, and the number of sampling points between each power well is adjusted to the first sampling number. The weight difference is the difference between the length weight and the preset length weight. The first sampling number is the product of the first preset sampling adjustment coefficient and the current number of sampling points. The current sampling point is the number of sampling points in the current power well.

[0116] The aforementioned device for determining the accuracy of cable data includes a processor and a memory. The first acquisition unit, the first comparison unit, and the first determination unit are all stored as program units in the memory. The processor executes these program units stored in the memory to achieve their respective functions. All of the aforementioned modules are located in the same processor; alternatively, the modules may be located in different processors in any combination.

[0117] The processor contains a kernel, which retrieves the corresponding program units from memory. One or more kernels can be configured, and adjusting kernel parameters can address the problem of low cable installation efficiency caused by the lack of accuracy verification of acquired cable data in existing technologies.
