Description

Technical Field

[0001] This application relates to the field of electricity meter technology, and in particular to an embedded positioning system and positioning method for electricity meters. Background Technology

[0002] An electricity meter (also known as a kilowatt-hour meter) is a specialized instrument used to measure electrical energy. Its core function is to convert the electrical energy consumed by users into quantifiable values ​​by recording parameters such as current, voltage, and power factor, providing basic data for electricity metering, electricity billing, and energy management. As the "nerve endings" of the power system, the electricity meter not only bears the mission of fair metering but is also a key device for smart grids, distributed energy resources, and user-side energy management.

[0003] Electricity meters have a long history of use in my country, dating back to the 19th century. However, their widespread adoption in some remote areas of my country is only just beginning to take shape.

[0004] With the upgrading and iteration of power equipment and the adjustment and optimization of power grid lines, the installation location of electricity meters also needs to be adjusted accordingly. They may be moved from one end of the line to the other, or they may be moved across transformer substations. Once the location of the electricity meter is moved, if the operator has difficulty finding the actual location of the electricity meter, not only will the power data stored in the meter be difficult to collect in real time, but it will also easily lead to the loss and damage of the electricity meter, increasing the operation and maintenance cost of the power grid system. Summary of the Invention

[0005] To facilitate the location determination of electricity meters, this application provides an embedded positioning system and method for electricity meters.

[0006] Firstly, this application provides an embedded positioning system for an electricity meter, which adopts the following technical solution: An embedded positioning system for an electricity meter includes a positioning module, a power supply module, a communication module, a storage module, and a data processing module installed inside the electricity meter. The positioning module is used to acquire location information; The power module is used to provide electrical energy to this positioning system; The communication module is used to transmit data between this system and the backend server; The storage module is used to store data; The data processing module is used for data analysis and correction.

[0007] With the above technical solution, when operators need to locate the electricity meter, since the positioning system is built into the electricity meter, the location information of the electricity meter can be obtained by acquiring the location information of the positioning module, and the electricity meter can be located so that the operators can find the electricity meter and read the data stored in the electricity meter.

[0008] The system's backend control positioning module acquires location information (including real-time location, signal strength of the positioning signal emitted by the positioning module, positioning range, etc.). This location information is captured by the data processing module, and after data analysis and correction, the analyzed and corrected location information is stored in the storage module for later analysis of movement paths by staff. On the other hand, the location information is sent to the system backend by the communication module (using wireless communication methods such as 4G or 5G) so that backend staff can know the real-time location of the electricity meter, the signal strength of the positioning signal emitted by the positioning module, and the positioning range.

[0009] Secondly, based on the aforementioned embedded positioning system for an electricity meter, this application also provides an embedded positioning method for an electricity meter.

[0010] An embedded positioning method for electricity meters adopts the following technical solution: The method includes the following processing steps: Location information is obtained through the positioning module; Based on the location information, match the power supply area information corresponding to the location information; Based on the power supply area information and the location information, match the line information corresponding to the power supply area information and the location information; A location feedback signal is generated based on the location information, the power supply area information, and the line information.

[0011] With the above technical solution, when the operator needs to locate the electricity meter, the system backend obtains the location information (including real-time location, signal strength of the location signal emitted by the location module, location range, etc.) through the control positioning module. Then, based on the location information, it matches the power supply area information of the real-time location corresponding to the location information. For example, the area included in power supply area A is defined and has clear boundaries and coordinates. Therefore, if the real-time location included in the location information is within the area included in power supply area A, the power supply area information of power supply area A can be matched based on this location information.

[0012] Then, the power supply area information and location information are matched with the corresponding line information. For example, there are multiple power supply lines in power supply area A, and there are three power supply lines at the real-time location corresponding to the location information (the number of power supply lines is based on actual considerations, and the specific number here is only for illustrative purposes). The three power supply lines are X, Y, and Z. Based on this power supply area information and location information, the line information containing the three power supply lines X, Y, and Z can be matched.

[0013] Next, the location information, power supply area information, and line information are integrated and aggregated into a location feedback signal. This location feedback signal is then sent to the system backend via a communication module. Once the system backend receives the location feedback signal, it can obtain the location information, power supply area information, and line information, thereby providing location guidance for staff to locate the electricity meter and improving the efficiency of electricity meter tracking.

[0014] In a preferred embodiment, this application can be further configured to match the power supply area information and the line information corresponding to the location information, including the following processing steps: Based on the positioning information, the positioning signal strength at the location corresponding to the positioning information is obtained; Based on the positioning signal strength, the positioning radius corresponding to the positioning signal strength is obtained; Based on the positioning information and the positioning radius, a positioning range is generated; Based on the location range, obtain the power supply line numbers covered within the location range; Line information is generated based on the power supply line number.

[0015] The above technical solution obtains the location signal strength corresponding to the location information. Since the terrain, signal obstruction, magnetic field interference and other factors vary at different locations, the location signal strength is also different. The location accuracy is different for different signal strengths. The location accuracy is reflected in the location radius. That is to say, the higher the location signal strength, the higher the location accuracy and the smaller the location radius. Conversely, the lower the location signal strength, the lower the location accuracy and the larger the location radius.

[0016] By drawing a circle with the real-time location corresponding to the positioning information as the center and the positioning radius as the radius, a circular area can be formed, which is the positioning range described in this method. The positioning range is reflected on the map as a specific area. Multiple power lines may exist within the positioning range, each with a unique number, known as the power line number. Based on the multiple power line numbers covered within the positioning range (or possibly just one power line), line information is formed, which includes the power line numbers covered within the positioning range.

[0017] In a preferred embodiment, this application can be further configured such that generating line information based on the power line number includes the following processing steps: If there are multiple power supply line numbers, the power supply lines corresponding to the multiple power supply line numbers are marked in the positioning range, based on the positioning range. Calculate the deviation distance from the center point of the positioning range to each power supply line; A route sequence table is generated based on the magnitude of multiple deviation distance values; Based on the route sequence table, route information is generated.

[0018] Multiple power supply lines exist within the location area. These lines need to be prioritized according to the actual situation, meaning the order in which they are investigated needs to be clearly defined to provide guidance for staff. Using the above technical solution, if multiple power supply line numbers exist within the location area, the power supply lines corresponding to these numbers are marked within the location area. For example, if there are two power supply routes, X and Y, then X and Y are virtually represented as a line (usually a straight line, also shown as a straight line in the attached diagram) that aligns with the direction of the power supply line. The straight line corresponding to X and the straight line corresponding to Y are then marked within the power supply area.

[0019] Then, the distance from the center point of the positioning range to each power supply line is calculated. This distance is called the deviation distance value. Different lines have different deviation distance values. The lines are sorted by the magnitude of the deviation distance values ​​to generate a line sequence table. Line information is generated based on the line sequence table to clarify the order of power supply line investigation, thereby providing work guidance for staff and improving the efficiency of electricity meter tracking.

[0020] In a preferred embodiment, this application can be further configured such that generating the route sequence table based on the magnitude of multiple deviation distance values ​​includes the following processing steps: If power supply lines with the same deviation distance value exist, obtain the positioning history information; Based on historical location information, historical movement routes are generated in chronological order and within a preset time span; Based on historical moving routes and each power supply line, generate deviation angle values ​​corresponding to different power supply lines; Based on the magnitude of multiple deviation angle values, a line sequence table is generated for power supply lines that have the same deviation distance value.

[0021] If power supply lines with the same deviation distance value exist, it is difficult to sort them. The above technical solution addresses this by acquiring historical positioning information, including positioning data from multiple positioning operations, when power supply lines with the same deviation distance value exist. Based on this historical positioning information, a historical movement route is generated according to the chronological order and a preset time span (i.e., duration). This historical movement route reflects the movement trajectory of the electricity meter.

[0022] Generally speaking, the line connecting two adjacent location information points is a straight line, meaning the connection between the positions of the electricity meter before and after a location transfer is a straight line. Using the straight line corresponding to the historical movement route as a reference, the angle between the straight line corresponding to each power supply line and the straight line corresponding to the historical movement route is measured; this angle value is called the deviation angle value.

[0023] Based on the magnitude of multiple deviation angle values, a line sequence table is generated for power supply lines with the same deviation distance value. The smaller the deviation angle value, the higher the degree of overlap between the historical moving line and the power supply line, indicating that the accuracy of the power supply line is higher; conversely, the larger the deviation angle value, the lower the degree of overlap between the historical moving line and the power supply line, indicating that the accuracy of the power supply line is lower.

[0024] In a preferred embodiment, this application can be further configured such that generating historical travel routes according to chronological order and a preset time span includes the following processing steps: Obtain online geographic atlas information; Generate online geographic atlases based on online geographic atlas information; According to the time sequence and the preset time span, the location coordinates corresponding to different historical location information are marked on the online geographic atlas; Connect adjacent location coordinates to generate historical movement routes.

[0025] Using the above technical solution, online geographic atlas information is obtained. This online geographic atlas information can be simply understood as the latest online map. After compiling and analyzing the online geographic atlas information, an online geographic atlas can be formed. According to the chronological order and a preset time span, the location coordinates corresponding to different historical positioning information are marked on the online geographic atlas. For example, marking the coordinates of two locations before and after the most recent location change will form a straight line, thus forming the historical movement route.

[0026] In a preferred embodiment, this application can be further configured such that generating historical travel routes according to chronological order and a preset time span includes the following processing steps: Obtain online geographic atlas information; Generate online geographic atlases based on online geographic atlas information; Mark the location coordinates corresponding to the earliest historical information and the current location information on the online geographic atlas in chronological order; Connect the location coordinates corresponding to the earliest historical information with the location coordinates corresponding to the current location information to generate a historical movement route.

[0027] The difference between this method and the aforementioned methods lies in the fact that, for an electricity meter that has undergone a location change, when it is necessary to generate a historical movement route, the location coordinates corresponding to the earliest historical information and the current location information are directly marked on the online geographic atlas according to the time sequence. The location coordinates corresponding to the earliest historical information and the location coordinates corresponding to the current location information can then be connected to generate the historical movement route. There is no need to obtain information based on the time span, which not only shortens the data processing process but also improves processing efficiency.

[0028] In summary, this application includes the following beneficial technical effects: 1. This positioning system is built into the electricity meter. When the electricity meter moves, the operator can use the positioning system to determine the location of the electricity meter, thereby improving the operator's work efficiency in tracking the electricity meter, reducing the possibility of power grid asset loss, and reducing the operation and maintenance cost of the power grid system. 2. When multiple power supply lines exist within the positioning range, the positioning system using this positioning method sorts the multiple power supply lines by comprehensively considering factors such as the distance from the real-time location to the power supply line and the line angle deviation, and sets the priority for investigation and search, thereby optimizing the movement path of staff and improving the efficiency of electricity meter tracking.

[0037] The following is in conjunction with the appendix Figure 1 -Appendix Figure 8 This application will be described in further detail.

[0038] This application discloses an embedded positioning system and positioning method for an electricity meter. The positioning method can be applied to this positioning system, and the executing entity of this method can be a server terminal that controls this positioning system.

[0039] An embedded positioning system and positioning method for an electricity meter includes a positioning module, a power supply module, a communication module, a storage module, and a data processing module installed inside the electricity meter.

[0040] The positioning module is used to obtain location information and can be a device structure with high-precision positioning, such as a GPS positioning module or a Beidou positioning module.

[0041] The power module is used to provide power to the positioning system. It can be a battery or a power supply mechanism with power extraction function, or a power supply mechanism with both a battery and a power extraction mechanism. The power of the power extraction mechanism can be stored in the battery so that the battery can provide power support to the positioning system in the event of a power outage or failure of the power extraction mechanism.

[0042] The communication module is used to transmit data between this system and the backend server, and can use wireless communication methods such as 4G or 5G. Of course, this communication module can also use wired communication mode, or a communication mode that combines wired and wireless communication. The two communication modes are mutually supportive to ensure the stability and reliability of information transmission and reception.

[0043] The storage module is used to store data, such as the location and time of each positioning and information collected by other sensors. The system backend and data processing module can access the data stored in the storage module at any time.

[0044] The data processing module is used for data analysis, correction, and integration.

[0045] When operators need to locate the electricity meter, they can obtain the location information of the positioning module through the positioning module, thus knowing the location of the electricity meter. This allows operators to find the electricity meter and read the data stored in it.

[0046] The system's backend control positioning module acquires location information (including real-time location, signal strength of the positioning signal emitted by the positioning module, positioning range, etc.). This location information is captured by the data processing module, and after data analysis and correction, the analyzed and corrected location information is stored in the storage module for later analysis of movement paths by staff. On the other hand, the location information is sent to the system backend by the communication module so that backend staff can know the real-time location of the electricity meter, the signal strength of the positioning signal emitted by the positioning module, and the positioning range.

[0047] Based on the above-mentioned embedded positioning system for an electricity meter, this application also discloses a positioning method for an electricity meter. This positioning method can be applied to the above-mentioned positioning system, as well as to other positioning systems that are compatible with it.

[0048] See attached document Figure 1 As shown, an embedded positioning method for an electricity meter includes the following processing steps: S101. Obtain location information through the positioning module.

[0049] In practice, when operators need to locate the electricity meter, the system backend obtains the location information by controlling the location module. The location information includes the real-time location, the signal strength of the location signal emitted by the location module, and the location range.

[0050] S102. Based on the location information, match the power supply area information corresponding to the location information.

[0051] In implementation, the power supply area information corresponding to the real-time location is matched based on the location information. For example, the area encompassed by power supply area A is defined, with clear boundaries and coordinates. Therefore, if the real-time location included in the location information is within the area encompassed by power supply area A, the power supply area information of power supply area A can be matched based on this location information.

[0052] S103. Based on the power supply area information and location information, match the line information corresponding to the power supply area information and location information.

[0053] In implementation, power supply area information and location information are matched with corresponding line information. For example, if there are multiple power supply lines in power supply area A, and the real-time location corresponding to the location information has three power supply lines (the number of power supply lines is based on actual considerations; the specific number here is only for illustrative purposes), and these three power supply lines are X, Y, and Z, then based on this power supply area information and location information, line information containing the three power supply lines X, Y, and Z can be matched.

[0054] S104. Based on the location information, power supply area information, and line information, generate a location feedback signal.

[0055] During implementation, location information, power supply area information, and line information are integrated and aggregated into a location feedback signal. This location feedback signal is then sent to the system backend via a communication module. Once the system backend receives the location feedback signal, it can obtain the location information, power supply area information, and line information, thereby providing location guidance for staff to locate electricity meters and improving the efficiency of electricity meter tracking.

[0056] See attached document Figure 2 As shown, in step S103, matching the line information corresponding to the power supply area information and the location information may include the following processing steps: S201. Based on the positioning information, obtain the positioning signal strength of the location corresponding to the positioning information.

[0057] In practice, the location signal strength corresponding to the location information is obtained. Due to differences in terrain elevation, signal obstruction, magnetic field interference, etc., the location signal strength is not the same. The location accuracy varies with the strength of the location signal, which is reflected in the location radius, as will be discussed in detail later.

[0058] S202. Based on the positioning signal strength, obtain the positioning radius corresponding to the positioning signal strength.

[0059] In practice, the higher the positioning signal strength, the higher the positioning accuracy and the smaller the positioning radius; conversely, the lower the positioning signal strength, the lower the positioning accuracy and the larger the positioning radius.

[0060] S203. Generate the positioning range based on the positioning information and positioning radius.

[0061] In practice, a circle is drawn with the real-time location corresponding to the positioning information as the center and the positioning radius as the radius. This forms a circular range, which is the positioning range mentioned in this method. The positioning range is reflected on the map as a specific area.

[0062] S204. Based on the location range, obtain the power supply line numbers covered within the location range.

[0063] During implementation, there may be multiple power supply lines within the location range, and each power supply line has a unique number, which is the power supply line number.

[0064] S205. Generate line information based on the power supply line number.

[0065] In practice, line information is generated based on the multiple power line numbers (or possibly one power line) covered within the location range. In other words, the line information includes the power line numbers covered within the location range.

[0066] See attached document Figure 3 As shown, in step S205, generating line information based on the power supply line number may include the following processing steps: S301. If there are multiple power supply line numbers, the power supply lines corresponding to the multiple power supply line numbers shall be marked in the positioning range based on the positioning range.

[0067] During implementation, multiple power supply lines exist within the location area. It is necessary to prioritize these power supply lines according to the actual situation, that is, to clarify the order of investigation of the power supply lines, so as to provide work guidance for the staff.

[0068] If multiple power line numbers exist within the location area, then the power lines corresponding to these multiple power line numbers are marked within the location area, using the location area as a base. For example, refer to the attached... Figure 7 As shown in the figure, the outer quadrilateral represents the area covered by the power supply station, the circle represents the area covered by the positioning range, the two straight lines in the figure correspond to two power supply lines respectively, and there are two power supply lines within the positioning range, namely X and Y. X and Y are then virtually formed into a line (usually a straight line) that matches the direction of the power supply line, and the straight line corresponding to X and the straight line corresponding to Y are marked in the power supply range.

[0069] S302. Calculate the deviation distance from the center point of the positioning range to each power supply line.

[0070] In implementation, refer to the appendix. Figure 7 and attached Figure 8 As shown, attached Figure 8 For the appendix Figure 7 A magnified view of the area shows the distance from the center point of the positioning range to each power supply line. This distance is called the deviation distance value. The deviation distance value varies for different lines. For example, see attached... Figure 8 The dashed line in the diagram represents the perpendicular line from the center of the positioning range to the power supply line. The length of this perpendicular line indicates the magnitude of the deviation distance.

[0071] S303. Generate a route sequence table based on the magnitude of multiple deviation distance values.

[0072] In practice, the lines are sorted by the magnitude of the deviation distance values ​​to generate a line sequence list. Based on the line sequence list, line information is generated to clarify the order of power supply line investigation, thereby providing work guidance for staff and improving the efficiency of electricity meter tracking.

[0073] For example, appendix Figure 8 In the positioning range, the distance from the center of the circle to the power supply line X is less than the distance from the center of the circle to the power supply line Y. In other words, the deviation distance of the power supply line X is less than the deviation distance of the power supply line Y. Therefore, in the line sequence table, the priority of the power supply line X is higher than that of the power supply line Y.

[0074] S304. Generate line information based on the line sequence table.

[0075] In practice, line information is generated based on the line sequence list to clarify the order of power supply line investigation, thereby providing work guidance for staff and improving the efficiency of electricity meter tracking.

[0076] See attached document Figure 4 As shown, in step S303, generating a line sequence table based on the magnitude of multiple deviation distance values ​​may include the following processing steps: S401. If there are power supply lines with the same deviation distance value, obtain the positioning history information.

[0077] In practice, if power supply lines with the same deviation distance value exist, it is difficult to sort them. When power supply lines with the same deviation distance value exist, location history information is obtained, which includes location information from multiple positioning operations.

[0078] S402. Based on historical positioning information, generate historical mobile routes in chronological order and according to a preset time span.

[0079] In practice, based on historical location information, historical movement routes are generated according to chronological order and a preset time span (i.e., duration). These historical movement routes reflect the movement trajectory of the electricity meter. Generally speaking, the line connecting two adjacent locations is a straight line, meaning the connection between the positions of the electricity meter before and after a single location transfer is a straight line.

[0080] S403. Based on the historical moving lines and each power supply line, generate the deviation angle value corresponding to different power supply lines.

[0081] In practice, the straight line corresponding to the historical moving line is used as a benchmark to measure the angle between the straight line corresponding to each power supply line and the straight line corresponding to the historical moving line. The angle value of this angle is called the deviation angle value.

[0082] S404. Based on the magnitude of multiple deviation angle values, generate a line sequence table of power supply lines with the same deviation distance value.

[0083] In practice, based on the magnitude of multiple deviation angle values, a line sequence table of power supply lines with the same deviation distance value is generated. The smaller the deviation angle value, the higher the degree of overlap between the historical moving line and the power supply line, indicating that the accuracy of the power supply line is higher; conversely, the larger the deviation angle value, the lower the degree of overlap between the historical moving line and the power supply line, indicating that the accuracy of the power supply line is lower.

[0084] See attached document Figure 5 As shown, in step S402, generating historical travel routes according to chronological order and a preset time span may include the following processing steps: S501. Obtain online geographic atlas information.

[0085] S502. Generate an online geographic atlas based on online geographic atlas information.

[0086] In practice, online geographic atlas information can be simply understood as the latest online map. After compiling and analyzing the online geographic atlas information, an online geographic atlas can be formed.

[0087] S503. Mark the location coordinates corresponding to different historical location information on the online geographic atlas according to the time sequence and the preset time span.

[0088] During implementation, the location coordinates corresponding to different historical location information are marked on the online geographic atlas according to the chronological order and the preset time span.

[0089] S504. Connect adjacent position coordinates to generate historical movement routes.

[0090] In practice, for example, by marking the coordinates of the two positions before and after the most recent position change, a straight line can be formed, thus forming the historical movement route.

[0091] See attached document Figure 6 As shown, in step S402, generating historical travel routes according to chronological order and a preset time span may also include the following processing steps: S601. Obtain online geographic atlas information.

[0092] S602. Generate an online geographic atlas based on online geographic atlas information.

[0093] In practice, online geographic atlas information can be simply understood as the latest online maps. After compiling and analyzing the online geographic atlas information, an online geographic atlas can be formed. If online geographic atlas information is unavailable, pre-downloaded offline maps can be used for subsequent operations.

[0094] S603. Mark the location coordinates corresponding to the earliest historical information and the current location information on the online geographic atlas in chronological order.

[0095] S604. Connecting the location coordinates corresponding to the earliest historical information with the location coordinates corresponding to the current location information to generate historical movement routes is in progress.

[0096] In implementation, the difference between the method described in S6 and the method described in S5 is that, for an electricity meter that has undergone a location change (an electricity meter equipped with this positioning method and positioning system), when it is necessary to generate a historical movement route, the location coordinates corresponding to the earliest historical information and the current positioning information are directly marked on the online geographic atlas in chronological order. The location coordinates corresponding to the earliest historical information and the location coordinates corresponding to the current positioning information can then be connected to generate the historical movement route. There is no need to obtain information based on the time span, which not only shortens the data processing process but also improves processing efficiency.

[0097] The embodiments described in this specific implementation are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
