[0015] Figure 1 A structural block diagram of a ground line real-time monitoring system for a power system according to an embodiment of the present invention is shown; Figure 2 The structure block diagram of the weight iteration module in this embodiment is shown. DETAILED DESCRIPTION

[0016] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0017] As the complexity and scale of power systems increase, traditional ground wire monitoring methods are unable to meet the requirements of real-time and accuracy. As an important part of the power system, the state of the ground wire directly affects the safety and stability of the system. Traditional monitoring methods usually rely on manual inspection or wired transmission systems, which have many limitations in coverage, real-time data transmission and maintenance costs.

[0018] In order to solve the problems existing in the above-mentioned prior art, the inventor proposes the solution of the present invention. One embodiment of the present invention provides a ground line real-time monitoring system for a power system, wherein: Figure 1 The structural block diagram of the corresponding system is shown in FIG. Figure 1 As shown, the system at least includes an image recognition module, a positioning determination module, a multi-dimensional labeling module and a state determination module.

[0019] First, with respect to the above-mentioned image recognition module, the image recognition module is configured to obtain a site view corresponding to the power system, and perform image recognition on the site view to determine each transmission area corresponding to different ground lines; Here, the power system can be understood as a system park for accommodating corresponding power equipment, which can be mainly used to provide corresponding power. In this embodiment, the image recognition module can further perform image recognition by obtaining the site view of the corresponding power system, so as to determine the transmission areas corresponding to different ground wires; it should be noted that the ground wire is a wire connected to the earth, the shell or the reference potential of zero in the electrical system or electronic equipment. In general electrical appliances, the ground wire is connected to the shell to prevent electric shock accidents caused by the internal insulation damage of the electrical appliance and the shell being charged. According to GB 50303-2015 "Construction Quality Acceptance Code for Building Electrical Engineering" and GB50169-2016 "Construction and Acceptance Code for Grounding Devices for Electrical Installation Engineering", the terminal connection of each device or appliance shall not exceed 2 wires or 2 wire terminals. This means that in the design and installation of the grounding device, the number of devices connected to each grounding point or grounding wire should be limited to two or less. This is to ensure the safety and effectiveness of the grounding system and avoid increased grounding resistance or failure of the grounding system due to connecting too many devices. Since the system park generally houses multiple power equipment, in order to manage the ground wires connected to each power equipment separately, it is necessary to determine the transmission areas corresponding to different ground wires based on the site top view.

[0020] Further, in this embodiment, the above-mentioned “the image recognition module is configured to obtain a site view corresponding to the power system, and perform image recognition on the site view to determine each transmission area corresponding to different ground lines” may also include the following contents: In response to the auxiliary acquisition terminal scanning the system identification code corresponding to the power system, acquiring a site view corresponding to the power system; Acquire the ground line images of different types, and determine the acquired ground line images as training subsets; Constructing an initial recognition model, and performing model training on the initial recognition model based on the local line images in the training subset to obtain a trained transmission recognition model; The site view is transmitted to the transmission recognition model, each line segment in the site view is determined, and each line segment is divided into regions based on a preset repeated recognition strategy to obtain transmission regions each having independent attributes.

[0021] For example, in this embodiment, the auxiliary acquisition terminal can be understood as a terminal device with a data processing function, which is mainly used by corresponding staff. In order to quickly obtain the site view of the power system, corresponding signs can be established in advance around different power systems. The signs can include a system identification code corresponding to the power system. When the staff needs to obtain the site view of a certain power system, the system identification code can be scanned by the auxiliary acquisition terminal to obtain the corresponding site view. Here, the system identification code can be understood as a QR code or a barcode, etc.; after obtaining the corresponding site view, an initial recognition model can be constructed based on a machine learning model or a deep network model, and corresponding different types of ground wire images are obtained to form a corresponding training subset. The initial recognition model is trained based on the ground wire images in the training subset to obtain a trained transmission recognition model; by transmitting the site view to the transmission recognition model, the ground wire segments located in the site view can be determined.

[0022] It should be noted that, from the above content, it can be seen that one power equipment may be configured with two ground wires. Therefore, in this case, in the subsequent monitoring of the ground wire, only one ground wire is required, thereby reducing the corresponding monitoring data volume and improving the corresponding data processing efficiency. Therefore, in this embodiment, the ground wire segments can be divided into regions based on the preset repeated identification strategy, thereby obtaining transmission areas with independent attributes.

[0023] Furthermore, in this embodiment, the above-mentioned “dividing each line segment into regions based on a preset distinguishing and repeating strategy to obtain transmission regions each having independent attributes” may also include the following method steps: Determine the electrical devices respectively connected to each ground line segment circuit along the extension direction of each ground line segment; Perform repeated screening on each power device, and divide the ground wire segments corresponding to the same power device into the same ground wire group, so as to obtain ground wire groups each having independent attributes; A circumscribed circle is formed based on all ground line segments in the same ground line group, and the site view is divided into regions based on the circumscribed circles corresponding to each ground line group, so as to obtain transmission regions with independent attributes.

[0024] For example, in this embodiment, in order to determine whether each ground line segment corresponds to the same power device, after determining each different ground line segment located in the site view, each power device connected to each ground line segment circuit can be determined along the extension direction of each ground line segment; further, each power device can be repeatedly screened, and when at least two ground line segments correspond to the same power device, they can be divided into the same ground line group, thereby obtaining ground line groups each having independent attributes; Here, after obtaining the corresponding ground line groups, in order to generate the corresponding transmission area based on each ground line group, a corresponding circumscribed circle can be formed based on all ground line segments in the same ground line group, and then the field view can be divided into corresponding areas based on the formed circumscribed circles to obtain transmission areas with independent attributes.

[0025] Secondly, in this embodiment, the above-mentioned positioning determination module is mainly configured to determine the corresponding transmission collection points in each transmission area based on a preset point determination strategy, and determine the point positioning information corresponding to each transmission collection point based on the satellite positioning information corresponding to the above view of the site.

[0026] It should be noted that after completing the determination of the different transmission areas located in the site view, in order to realize the subsequent monitoring of the ground line segments corresponding to each transmission area, it is necessary to determine the transmission collection points in the corresponding transmission areas. Here, the transmission collection points can be understood as the points for corresponding status monitoring. The method of setting points for monitoring can greatly reduce the corresponding monitoring data volume, while ensuring the accuracy of monitoring and improving the corresponding data processing efficiency.

[0027] Further, in this embodiment, the above-mentioned “the positioning determination module is configured to determine the corresponding transmission collection points in each transmission area based on a preset point determination strategy, and determine the positioning information of each point corresponding to each transmission collection point based on the satellite positioning information corresponding to the view on the site” may also include: The positioning determination module is configured to determine the corresponding transmission collection points in each transmission area based on a preset point determination strategy, and determine the positioning information of each point corresponding to each transmission collection point based on the satellite positioning information corresponding to the above view of the site, including: Determine the location attributes of all ground line segments located in the same transmission area, wherein the location attributes include overlapping attributes and dispersion attributes; When the position attributes of all ground line segments in any transmission area are overlapping attributes, corresponding overlapping points are determined in the transmission area, and the overlapping points are determined as transmission collection points; When the position attributes of all ground line segments in any transmission area are scattered attributes, the corresponding longest ground line segment is determined in the transmission area, and the center point of the ground line segment is determined as the transmission collection point; In response to completing the determination of the transmission collection points corresponding to all transmission areas, respectively, obtaining satellite positioning information corresponding to the site top view; Based on the satellite positioning information, the positioning information of each point corresponding to each transmission collection point is determined.

[0028] For example, in this embodiment, when the corresponding ground wire segments of each power device located in the power system are wired, the ground wire segments corresponding to the same power device may overlap, that is, at least two ground wire segments are placed crosswise, and the corresponding position attribute is an overlapping attribute. In this case, the corresponding overlapping point can be determined as the transmission collection point, so that the two ground wire segments can be collected simultaneously; and when there is no corresponding overlap between the ground wire segments corresponding to the same power device, that is, the corresponding position attribute is a scattered attribute, in this case, the corresponding longest ground wire segment can be determined in the transmission area, and the center point of the segment corresponding to the ground wire segment can be determined as the transmission collection point; and after completing the determination of the transmission collection points corresponding to all transmission areas, the satellite positioning information of the corresponding site view can be further obtained, and the positioning information of each point corresponding to each transmission collection point can be determined based on the satellite positioning information, thereby completing the positioning of the site view and each transmission collection point.

[0029] Next, in this embodiment, the above-mentioned multi-dimensional marking module can be configured to mark each transmission collection point in the site view with multi-dimensional specifications, and send the marked site view and the positioning determination set including the satellite positioning information and the positioning information of each point to the assisting collection end.

[0030] It should be noted that, in this embodiment, after the field view is completed to determine the corresponding transmission and collection points, in order to enable the assisting collection end to set up the corresponding data collection unit at each transmission and collection point, each transmission and collection point can be marked with multi-dimensional specifications in the field view, and the marked field view and the positioning determination set including the satellite positioning information and the positioning information of each point are sent to the assisting collection end; so that the assisting collection end can determine the location of each transmission and collection point through the corresponding positioning determination set and the corresponding mark, thereby completing the setting of the data collection unit, so that the data collection of each transmission and collection point can be completed based on the data collection unit in the future. Here, the data collection unit may include a current sensor and a temperature sensor.

[0031] Further, in this embodiment, the above-mentioned "the multi-dimensional marking module is configured to mark each transmission collection point in the site view in a multi-dimensional specification, and send the marked site view and the positioning determination set including the satellite positioning information and the positioning information of each point to the assisting collection end", may also include the following contents: Acquire the contours of each region corresponding to each transmission region, and mark the contours of each region with a pixel of a preset pixel value; Determine the size of each point corresponding to the preset coefficient based on each transmission size corresponding to each transmission area, and generate each initial area corresponding to each point size with each transmission collection point as the center in the site view, and adjust the initial area based on the transmission area corresponding to the same transmission collection point to obtain each adjustment area; Establishing display layers of corresponding preset sizes that are linked to the transmission areas respectively; Adjusting the adjustment sizes corresponding to the adjustment areas to the preset sizes, and filling the obtained enlarged areas corresponding to the adjustment areas into the corresponding display layers; The site view is configured to call a corresponding display layer for display in response to any terminal interacting with any transmission area; The marked site view and the positioning determination set including the satellite positioning information and the positioning information of each point are sent to the auxiliary collection end.

[0032] For example, in this embodiment, in order to mark each transmission collection point in the site view, the following method can be used: First, the area contour corresponding to the transmission area can be obtained, and the area contour can be marked with pixels of a preset pixel value. The preset pixel value can correspond to a more conspicuous color such as red to ensure that the assisting acquisition end can quickly determine the corresponding transmission area; Next, the transmission dimensions corresponding to the transmission areas can be determined, and the product calculation can be performed based on the retrieved preset coefficients to obtain the dimensions of the points corresponding to the transmission areas. Thus, an initial area with the transmission collection point as a circle can be generated based on the corresponding point dimensions in the site view, and the initial area can be regionally adjusted based on the transmission area corresponding to the same transmission collection point to obtain each adjusted area. Next, display layers of corresponding preset sizes that are linked to the transmission areas can be established, and the corresponding adjustment sizes can be adjusted to the preset sizes, so that the enlarged areas corresponding to the adjustment areas can be filled into the display layer; Then, the site view can be configured to respond to any terminal interacting with any transmission area, and call the corresponding display layer for display; Finally, after completing the above configuration, the marked site view and the positioning determination set including the satellite positioning information and the positioning information of each point can be sent to the assisting collection end, so as to facilitate the assisting collection end to quickly determine the corresponding transmission collection points and further complete the setting of the data collection unit for each transmission collection point.

[0033] Furthermore, in this embodiment, the above-mentioned "determining the size of each point corresponding to the preset coefficient based on each transmission size corresponding to each transmission area, and generating each initial area corresponding to each point size with each transmission collection point as the center in the site view, and adjusting the initial area based on the transmission area corresponding to the same transmission collection point to obtain each adjustment area" may also include the following steps: Retrieving a preset coefficient, and multiplying each transmission size corresponding to each transmission area by the preset coefficient to obtain the size of each point; Based on the size of each point, initial areas corresponding to the size of each point are generated in the site view with each transmission collection point as the center, and it is determined whether there is an overlapping part between each initial area and each corresponding transmission area; When there is an overlapping portion between any initial region and the corresponding transmission region, the corresponding overlapping portion is removed from the initial region to obtain each adjustment region.

[0034] For example, in this embodiment, since the transmission collection points corresponding to different transmission areas may be located at different positions, the initial areas generated corresponding to the sizes of the points may have overlapping parts with the transmission area. In order to ensure that the areas corresponding to the transmission collection points can be located in the transmission area, it is necessary to remove the corresponding overlapping parts of the initial areas, so as to obtain the adjustment areas respectively located in the different transmission areas.

[0035] Finally, in this embodiment, the above-mentioned status determination module can be mainly configured to respond to the configuration completion signal sent by the assisting acquisition terminal, periodically obtain the multi-dimensional acquisition signals corresponding to each transmission acquisition point based on the Lora technology, and determine the status of each transmission acquisition point based on the multi-dimensional acquisition signals corresponding to the same transmission acquisition point, so as to obtain the operating status corresponding to each transmission acquisition point.

[0036] For example, in this embodiment, when the assisting acquisition terminal receives the corresponding marked field view and the corresponding positioning information, it can start to set the data acquisition units of different transmission and acquisition points. After completing the corresponding configuration, the assisting acquisition terminal can send a corresponding configuration completion signal to notify the corresponding information, so that the Lora technology can be used to periodically obtain the corresponding multi-dimensional acquisition signal to further determine the operating status corresponding to each transmission and acquisition point.

[0037] Further, in this embodiment, the above-mentioned "the state determination module is configured to respond to the configuration completion signal sent by the assisting acquisition terminal, periodically acquire the multi-dimensional acquisition signals corresponding to each transmission acquisition point based on the Lora technology, and determine the state of each transmission acquisition point based on the multi-dimensional acquisition signals corresponding to the same transmission acquisition point, to obtain the operating state corresponding to each transmission acquisition point", may also include the following contents: In response to receiving the configuration completion signal sent by the assisting acquisition terminal, periodically acquiring multi-dimensional acquisition signals corresponding to each transmission acquisition point based on the Lora technology, wherein the multi-dimensional acquisition signal includes a current acquisition signal and a temperature acquisition signal; Determine the corresponding current evaluation value and temperature evaluation value based on the current acquisition signal and the temperature acquisition signal respectively, and determine the total evaluation value corresponding to the transmission acquisition point based on the current evaluation value and the temperature evaluation value; The operation states corresponding to the transmission and collection points are determined based on the evaluation total values ​​corresponding to the transmission and collection points.

[0038] For example, in this embodiment, the data acquisition unit corresponding to each transmission collection point can include a corresponding temperature sensor and a current sensor, so that the corresponding current collection signal and the temperature collection signal can be obtained, and further corresponding signal evaluation can be performed on the collection signals of different dimensions, and the operating states corresponding to the transmission collection point can be determined based on the obtained total evaluation value.

[0039] It should be noted that, based on the characteristics of the ground wire segment, under normal circumstances, the current corresponding to each transmission and collection point should be 0 or have a minimum value, and the temperature should be room temperature; if the current at a certain transmission and collection point is large or the temperature is high, it indicates that the power equipment corresponding to the transmission and collection point has an abnormality. Therefore, the corresponding operating state can be determined as an abnormal state, otherwise it is a normal state.

[0040] Further, in this embodiment, the above-mentioned “determining the corresponding current evaluation value and temperature evaluation value based on the current acquisition signal and the temperature acquisition signal, respectively, and determining the total evaluation value corresponding to the transmission acquisition point based on the current evaluation value and the temperature evaluation value” may also include: Normalizing the current acquisition signal and the temperature acquisition signal respectively to obtain a first value and a second value corresponding to the current acquisition signal and the temperature acquisition signal respectively; Retrieving a first weight value and a second weight value corresponding to the current acquisition signal and the temperature acquisition signal, respectively, and performing product calculations on the first value and the second value, respectively, by the first weight value and the second weight value, to obtain a current evaluation value and a temperature evaluation value corresponding to the current acquisition signal and the temperature acquisition signal, respectively; The current evaluation value and the temperature evaluation value are summed up to obtain a total evaluation value corresponding to the transmission collection point.

[0041] It should be noted that the above-mentioned first weight value and second weight value are both preset and stored, and their specific values ​​are not limited in this embodiment.

[0042] Here, from the above content, it can be seen that the total evaluation value is obtained by summing the current evaluation value and the temperature evaluation value, the current evaluation value is obtained by multiplying the first weight value and the first numerical value, and the temperature evaluation value is obtained by multiplying the second weight value and the second numerical value. Based on this, since the operating state determined by the numerical comparison result may have a certain deviation from the actual situation, in order to improve the corresponding determination accuracy, the corresponding weight values ​​can be updated and trained in real time to realize the process of updating and iterating each weight value, thereby continuously improving the corresponding determination accuracy.

[0043] Here, if Figure 2 As shown, the update iteration of each weight value can be achieved through the weight iteration module: Among them, the weight iteration module is configured as: Obtain the actual evaluation value input by the system management end based on any transmission collection point, and compare the actual evaluation value corresponding to the same transmission collection point with the total evaluation value; When the actual evaluation value is greater than the total evaluation value, increasing training is performed on the first weight value and the second weight value respectively; When the actual evaluation value is less than the total evaluation value, the first weight value and the second weight value are respectively subjected to reduction training; The first weight value and the second weight value after training are obtained by the following formula: ; in, The first weight value Increase the number of training sessions. The first weight value The training constant value of The first weight value Reduce the number of training sessions. is the first weight value after training, The second weight value Increase the number of training sessions. The second weight value The training constant value of The second weight value Increase or decrease the number of training sessions.

[0044] In summary, the real-time monitoring system for ground wires in power systems has brought significant beneficial effects. First, the system realizes real-time monitoring of the ground wire status. Through wireless transmission technology, data can be quickly obtained in a wide area, thereby improving the timeliness and accuracy of the data. This real-time monitoring capability enables operation and maintenance personnel to detect ground wire faults or abnormalities in a timely manner, reducing the frequency and labor costs of traditional manual inspections; secondly, due to the strong anti-interference ability and long-distance transmission characteristics of LoRa technology, the stability of the system in complex environments has been significantly improved, ensuring the reliability of data transmission. This reduces the difficulty and cost of system maintenance and improves the overall stability of the power system; finally, the low-power design of the system greatly extends the operating time of the sensor and reduces the need for frequent battery replacement. This not only reduces maintenance costs, but also improves the sustainability of the system.
