Description

Technical Field

[0001] This invention relates to the field of power system technology, and in particular to a method, apparatus and medium for recycling electricity meters. Background Technology

[0002] Power supply companies recycle a large number of electricity meters every year. For example, a typical municipal power supply company can recycle up to 300,000 dismantled electricity meters annually. These dismantled meters are usually sorted manually. However, due to the sheer number of meters, manual sorting at the sorting site is extremely inconvenient and prone to errors. Furthermore, electricity meters typically have one-dimensional barcodes affixed to their surfaces for identification. However, these barcodes on dismantled meters are often damaged or illegible. Therefore, using one-dimensional barcodes to identify different meters obviously presents numerous problems when dealing with dismantled meters.

[0003] Therefore, there is an urgent need for a method that can effectively assist in the recycling of electricity meters without relying on one-dimensional barcodes. Summary of the Invention

[0004] One of the objectives of this invention is to provide a method, apparatus, and medium for recycling electricity meters.

[0005] According to one aspect of this application, a method for recycling electricity meters is provided, comprising: S11. Obtain RFID tag information and image information about multiple energy meters to be sorted; wherein, the multiple energy meters to be sorted are arranged according to a target matrix, and each energy meter to be sorted corresponds to matrix coordinates in the image information; S12. Determine the current candidate matrix coordinates of the current candidate energy meters to be sorted based on the current sorting type and the damage status information corresponding to the matrix coordinates; S13. Obtain the RFID tag signal stream and image information stream of the current energy meter to be sorted; wherein, the RFID tag signal stream includes one or more first timestamps and the current RFID tag corresponding to each first timestamp, and the image information stream includes one or more second timestamps and the current matrix coordinates corresponding to each second timestamp. S14. Determine the correspondence between the RFID tag and matrix coordinates, damage status and list status of each current candidate energy meter to be sorted based on the first timestamp, the current RFID tag, the second timestamp, the current matrix coordinates and the recycling list, so as to automatically generate a sorting report. S15. Repeat steps S12 to S14 until all sorting types of sorting operations are completed for multiple energy meters to be sorted.

[0006] According to another aspect of this application, a computer device is provided, including a memory and a processor, wherein a computer program capable of being loaded by the processor and executing the methods described above is stored in the memory.

[0007] According to another aspect of this application, a computer-readable storage medium is provided, storing a computer program that can be loaded by a processor and executed as described above.

[0008] Compared to existing technologies, this application sorts multiple energy meters at a time by acquiring RFID tag information and image information of multiple energy meters to be sorted. It does not rely on one-dimensional barcodes, but instead uses an RFID reader / writer and a camera device capable of simultaneously acquiring information from multiple energy meters to be sorted, providing a foundation for sorting multiple energy meters at a time. Furthermore, based on the current sorting type and the damage status information corresponding to the matrix coordinates, the current candidate matrix coordinates of the current candidate energy meters to be sorted are determined, enabling sequential sorting and providing a basis for accurate sorting. Furthermore, during the user sorting process, the RFID tag signal stream and image information stream of the current energy meters to be sorted are acquired. Based on the RFID tag signal stream and image information stream, the correspondence between the RFID tags and matrix coordinates, damage status, and list status is determined, automatically generating a sorting report without the user's awareness. This achieves efficient and accurate assistance to users in recycling energy meters without relying on one-dimensional barcodes. Attached Figure Description

[0016] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.

[0017] refer to Figure 1This invention provides a flowchart of a method for recycling electricity meters, the method including steps S11, S12, S13, S14, and S15. In step S11, RFID tag information and image information of multiple energy meters to be sorted are acquired; wherein, the multiple energy meters to be sorted are arranged according to a target matrix, and each energy meter to be sorted corresponds to matrix coordinates in the image information; in step S12, the current candidate matrix coordinates of the current candidate energy meter to be sorted are determined according to the current sorting type and the damage status information corresponding to the matrix coordinates; in step S13, RFID tag signal stream and image information stream of the current energy meter to be sorted are acquired; wherein, the RFID tag signal stream includes one or more first timestamps and the current RFID tag corresponding to each first timestamp, and the image information stream includes one or more second timestamps and the current matrix coordinates corresponding to each second timestamp; in step S14, the correspondence between the RFID tag and matrix coordinates, damage status, and list status of each current candidate energy meter to be sorted is determined according to the first timestamp, the current RFID tag, the second timestamp, the current matrix coordinates, and the recycling list, so as to automatically generate a sorting report; in step S15, steps S12 to S14 are repeated until all sorting operations of all sorting types of multiple energy meters to be sorted are completed. In some embodiments, the electricity meter typically has an RFID electronic tag built in.

[0018] Specifically, in step S11, RFID tag information and image information of multiple energy meters to be sorted are acquired; wherein, the multiple energy meters to be sorted are arranged according to a target matrix, and each energy meter to be sorted corresponds to matrix coordinates in the image information. In some embodiments, an imaging device is used to capture image information of multiple energy meters to be sorted. The imaging device has an RFID reader / writer installed on one side of the camera to acquire the RFID tag information of multiple energy meters to be sorted. In some embodiments, the RFID reader / writer can acquire information of multiple RFID tags simultaneously, but ordinary RFID readers / writers cannot acquire the location information of these multiple RFID tags. This embodiment uses a low-cost ordinary RFID reader / writer to achieve intelligent assistance in recycling energy meters. It improves automation while reducing costs. In some embodiments, the target matrix arrangement includes, but is not limited to, 3x4 (e.g., three rows and four columns), 2x3 (e.g., two rows and three columns), etc. For example, 12 energy meters to be sorted are placed on the workbench according to a 3x4 target matrix. The image information of the 12 energy meters to be sorted is captured by a camera device, and the RFID tag information (e.g., R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12) of the 12 energy meters to be sorted is acquired by an RFID reader / writer located on one side of the camera of the camera device. In some embodiments, each energy meter to be sorted corresponds to matrix coordinates in the image information. For example, in a 3x4 matrix arrangement, the matrix coordinates are: 11 (row 1, column 1), 12, 13, 14, 21, 22, 23, 24, 31, 32, 33, 34. In some embodiments, the camera device includes, but is not limited to, electronic devices with camera functions such as tablet computers and mobile phones. For example, the energy meter recycling APP of this embodiment is installed on electronic devices such as tablet computers and mobile phones. In some embodiments, the shooting interface can be divided into multiple grids of the target matrix arrangement to guide the user to place each energy meter to be sorted into the corresponding grid during shooting. In other embodiments, the camera device is pre-set at a fixed angle (e.g., at which the camera device can capture multiple energy meters placed on the workbench that need to be sorted in this operation). A grid of target matrices is pre-set on the workbench, and the user simply places the energy meters to be sorted within the corresponding grid. Each grid corresponds to matrix coordinates. In this embodiment, by placing multiple energy meters to be sorted at once and performing intelligent sorting on these multiple energy meters each time, efficiency and sorting accuracy are improved.

[0019] In step S12, the current candidate matrix coordinates of the current candidate energy meters to be sorted are determined based on the current sorting type and the damage status information corresponding to the matrix coordinates. In some embodiments, the sorting type includes, but is not limited to, damaged energy meters and undamaged energy meters. Damage status information includes, but is not limited to, damaged and undamaged. For example, each energy meter to be sorted placed at each matrix coordinate corresponds to damage status information. In some embodiments, image recognition technology can be used to detect the damage status of the energy meters to be sorted placed at each matrix coordinate. In some embodiments, the current candidate energy meters to be sorted include those selected from multiple energy meters to be sorted in this batch based on the current sorting type and the damage status information corresponding to the matrix coordinates. The matrix coordinates of the current candidate energy meters to be sorted are called the current candidate matrix coordinates. In some embodiments, the current candidate matrix coordinates match the current sorting type. For example, if the current sorting type includes damaged energy meters, then the damage status information corresponding to the current candidate matrix coordinates includes damaged. In some embodiments, identification information (e.g., color coding, symbol coding, etc.) is added to the current candidate matrix coordinates to prompt the user to pick up the current candidate energy meter at the marked current candidate matrix coordinates. In this embodiment, different sorting types guide the user to sort energy meters of different sorting types sequentially to reduce sorting errors. For a detailed explanation of this part, please refer to the corresponding embodiments below; it will not be repeated here.

[0020] In step S13, the RFID tag signal stream and image information stream of the current energy meter to be sorted are acquired. The RFID tag signal stream includes one or more first timestamps and the current RFID tag corresponding to each first timestamp. The image information stream includes one or more second timestamps and the current matrix coordinates corresponding to each second timestamp. For example, after identifying the current candidate matrix coordinates for the current sorting type, the user begins to remove the current candidate energy meter to be sorted at the identified current candidate matrix coordinates. In this embodiment, the correspondence between the RFID tag and matrix coordinates, damage status, and list status is determined by acquiring the RFID tag signal stream and image information stream of the user removing the current candidate energy meter to be sorted. In some embodiments, the current sorting process can also be monitored based on the RFID tag signal stream and image information stream. In some embodiments, the current RFID tag includes, but is not limited to, an RFID tag that disappears at a certain first timestamp (e.g., when an RFID tag disappears, the first timestamp and the disappeared RFID tag are triggered to be recorded), or an RFID tag whose RFID signal strength drops sharply at the corresponding first timestamp (e.g., when an RFID tag signal strength drops sharply, the first timestamp and the RFID tag are triggered to be recorded). In some embodiments, the current matrix coordinates include, but are not limited to, the matrix coordinates at which the energy meter to be sorted disappears at the corresponding second timestamp when image information is identified using image technology (e.g., when the image identifies the disappearance of the energy meter to be sorted at a certain matrix coordinate, the second timestamp and the matrix coordinate at this time are triggered to be recorded), or the matrix coordinates at which the pixel of the energy meter to be sorted undergoes a sudden change at the corresponding second timestamp (e.g., the size of the energy meter to be sorted suddenly increases, or the pixel area suddenly decreases, etc., as shown in the image information). In some embodiments, one or more first timestamps are arranged in chronological order, and the current RFID tags corresponding to each first timestamp are also arranged in order. One or more second timestamps are arranged in chronological order, and the current matrix coordinates corresponding to each second timestamp are also arranged in order. In some embodiments, first timestamps and second timestamps arranged in the same order can be grouped together, and the matrix coordinates, damage status information, and RFID tags corresponding to this group of first timestamps and second timestamps can be grouped together. In other embodiments, to improve accuracy, the corresponding first timestamp and second timestamp can also be determined based on the difference between the first timestamp and the second timestamp. This determines the corresponding matrix coordinates, damage status information, and RFID tags. In this embodiment, a sorting report can be generated without the user's awareness when the user takes away the current candidate energy meter to be sorted.For example, a user can take one or two current candidate energy meters to be sorted at a time. The system automatically determines the correspondence between the RFID tag and matrix coordinates, damage status and list status of each current candidate energy meter to be sorted based on the RFID tag signal stream and image information stream, so as to automatically generate a sorting report.

[0021] In step S14, the correspondence between the RFID tag and matrix coordinates, damage status, and list status of each current candidate energy meter to be sorted is determined based on the first timestamp, the current RFID tag, the second timestamp, the current matrix coordinates, and the recycling list, so as to automatically generate a sorting report. In this embodiment, without relying on one-dimensional barcodes, the correspondence between the RFID tag and matrix coordinates, damage status, and list status of each current candidate energy meter to be sorted is determined based on the RFID tag signal stream and image information. In some embodiments, the correspondence between the RFID tag and matrix coordinates, damage status, and list status can be determined based on the difference between the first timestamp and the second timestamp. For a detailed explanation of this part, please refer to the corresponding embodiment below, which will not be repeated here.

[0022] In step S15, steps S12 to S14 are repeated until all sorting types of the multiple energy meters to be sorted are completed. For example, each sorting type corresponds to one cycle of steps S12 to S14 to achieve the goal of completing all sorting types of sorting operations for the multiple energy meters to be sorted.

[0023] In some embodiments, the current sorting type includes damaged energy meters and undamaged energy meters. Step S12 includes steps S121 (not shown) and S122 (not shown). In S121, image recognition technology is used to identify the damage status of each energy meter to be sorted in the image information to determine the damage status information corresponding to each matrix coordinate in the image information. The damage status information includes damaged and undamaged. In step S122, the current candidate matrix coordinates of the current candidate energy meters to be sorted are determined according to the order of damaged and undamaged energy meters. The current candidate matrix coordinates conform to the corresponding current sorting type. In some embodiments, the angle and position of the camera device can be fixed. A grid matching the target matrix is ​​set on the workbench used to place the energy meters to be sorted, so that the energy meters to be sorted in the captured image information are on the corresponding matrix coordinates. During each sorting, the user only needs to place the energy meters to be sorted on the workbench. For each matrix coordinate in the image information, image recognition technology is used to identify whether there is an energy meter to be sorted and the damage status of the energy meter to be sorted at that matrix coordinate. In some embodiments, the presence of a meter to be sorted on a matrix coordinate system can be detected using a YOLO model. For example, the YOLO model can be trained using a large number of meter images to enable it to identify meters in the images, thereby determining whether a meter to be sorted exists on the matrix coordinate system. In some embodiments, the meter to be sorted in the image information can be divided into multiple smaller images according to the matrix coordinate system. Each smaller image is then input into the YOLO model to detect whether a meter to be sorted exists in that smaller image. For example, in a 3x4 target matrix arrangement, the image information can be divided into 12 grids, with each grid serving as a smaller image. In some embodiments, the damage status of the meter to be sorted can be identified using an image classification model. For example, an image classification model can be trained based on a deep learning architecture (e.g., ResNet, MobileNet), using a large number of meter images with different degrees of damage, normal meter images, and corresponding image labels (e.g., damaged label, undamaged label), to enable the image classification model to identify damaged and undamaged meters to be sorted. Of course, those skilled in the art will understand that the image recognition technology described above is merely an example, intended to illustrate that image recognition technology can be used to identify the energy meters to be sorted in image information and to identify the damage status of the energy meters to be sorted. Other existing or future image recognition technologies that are applicable to this embodiment are also within the scope of protection of this application and are incorporated herein by reference. In some embodiments, after identifying the damage status of the energy meters to be sorted at each matrix coordinate in the image information, the current candidate matrix coordinates of the current candidate energy meters to be sorted are determined according to the order of damaged energy meters and undamaged energy meters.For example, in a 3x4 target matrix arrangement, the damage status of the energy meters to be sorted, identified by image recognition technology at each matrix coordinate, is as follows: Matrix coordinate 11: Damaged; Matrix coordinate 12: Undamaged; Matrix coordinate 13: Damaged; Matrix coordinate 14: Damaged; Matrix coordinate 21: Undamaged; Matrix coordinate 22: Undamaged; Matrix coordinate 23: Damaged; Matrix coordinate 24: Damaged; Matrix coordinate 31: Undamaged; Matrix coordinate 32: Undamaged; Matrix coordinate 33: Damaged; Matrix coordinate 34: Damaged. Therefore, the current candidate matrix coordinates for the current sorting type are: 11, 13, 14, 23, 24, 33, 34. The next current candidate matrix coordinates for the current sorting type are: 12, 21, 22, 31, 32.

[0024] In some embodiments, step S122 includes: if the current sorting type includes damaged energy meters, selecting energy meters whose damage status information in the image information is damaged as current candidate energy meters to be sorted, and marking the current candidate energy meters; if the current sorting type includes undamaged energy meters, selecting the remaining energy meters to be sorted as current candidate energy meters to be sorted; wherein, the remaining energy meters to be sorted include the energy meters to be sorted in this sorting process excluding the damaged ones. In some embodiments, the marking methods include, but are not limited to, color marking, symbol marking, and obscuring energy meters that are not current candidate energy meters to be sorted, to prompt the user which are the current candidate energy meters to be sorted.

[0025] In some embodiments, step S14 includes steps S141 (not shown), S142 (not shown), and S143 (not shown). S141: For each first timestamp, determine the currently missing RFID tag corresponding to the first timestamp based on the current RFID tag corresponding to the first timestamp; for each second timestamp, determine the current disappearance matrix coordinates corresponding to the second timestamp based on the current matrix coordinates; S142: Determine the target second timestamp corresponding to the first timestamp based on the difference between the first and second timestamps, and use the currently missing RFID tag corresponding to the first timestamp as the RFID tag corresponding to the first timestamp, and use the damage state corresponding to the current disappearance matrix coordinates of the target second timestamp as the damage state corresponding to the first timestamp, to determine the correspondence between RFID tag information and damage state; wherein the difference between the first timestamp and the target second timestamp is equal to or less than the target difference; S143: Determine the correspondence between RFID tag information and list status based on the recycling list; wherein the recycling list includes RFID tag information of multiple energy meters that need to be recycled, and the list status is either included in the list or not in the list. In some embodiments, the camera continuously captures and identifies data. When it detects the disappearance of a sorted energy meter or a sudden pixel change at a certain matrix coordinate, it triggers the recording of a second timestamp at this time and uses the matrix coordinate where the energy meter disappeared as the current matrix coordinate. In some embodiments, if the recording of the second timestamp is triggered when a sudden pixel change is detected, then after determining that the energy meter corresponding to that matrix coordinate has disappeared, that matrix coordinate is determined as the current disappeared matrix coordinate. If the energy meter corresponding to that matrix coordinate has not disappeared, the second timestamp is deleted. Similarly, the RFID reader continuously reads and writes RFID tag information. When it detects a disappeared RFID tag or a sudden drop in RFID signal strength, it triggers the recording of a first timestamp at this time and uses the disappeared RFID tag as the currently disappeared RFID tag. In some embodiments, if the recording of the first timestamp is triggered when a sudden drop in RFID signal strength is detected, then after determining that the RFID tag signal has disappeared, that RFID tag is determined as the currently disappeared RFID tag. If the RFID tag ultimately does not disappear, the first timestamp is deleted. For example, the currently disappearing RFID tags corresponding to the first timestamp include: T1 (e.g., the first timestamp is T1): R1 (e.g., the currently disappearing RFID tags corresponding to T1 include R1); T2: R2; T3: R3; T4: R4; T5: R5; T6: R6. The currently disappearing matrix coordinates corresponding to the second timestamp include: t1 (e.g., the second timestamp is t1): 11 (e.g., the currently disappearing matrix coordinates corresponding to the second timestamp t1 include 11); t2: 13; t3: 21; t4: 24; t5: 31; t6: 33; t7: 34.If the difference between T1 and t1 is less than the target difference, then R1 is determined to correspond to 11, and the damage status information corresponding to matrix coordinate 11 is taken as the damage status information corresponding to R1. In some embodiments, the recycling list records the RFID tag information of multiple electricity meters that need to be recycled. The system queries whether R1 exists in the recycling list. If it exists, the list information for R1 is recorded as "in the list"; otherwise, it is recorded as "not in the list". In this embodiment, it does not rely on one-dimensional barcodes, but only on RFID tag information and image recognition. Furthermore, it does not limit the number of current candidate electricity meters to be sorted that a user can take at one time. The system automatically determines the correspondence between RFID tags and damage status, and list status without the user's awareness, thereby automatically generating a sorting report.

[0026] In some embodiments, the method further includes step S144 (not shown), whereby if an erroneous second timestamp exists, an error message is generated to monitor the current sorting process; wherein the damage status information corresponding to the erroneous second timestamp does not match the current sorting type. In some embodiments, the second timestamp corresponds to the current disappearance matrix coordinates, and each matrix coordinate corresponds to damage status information. For example, the user's sorting process is monitored in real time, and if the damage status information corresponding to the second timestamp does not match the current sorting type, an error message is generated. For example, if the current sorting type is damaged, but the damage status information corresponding to the second timestamp is undamaged, then it is determined that the current sorting type does not match the damage status information corresponding to the second timestamp. In some embodiments, the error message includes a voice prompt.

[0027] In some embodiments, the system further includes step S17 (not shown), whereby the target sorting location corresponding to each current candidate energy meter to be sorted is determined based on its damage status and list status, to generate a prompt message; wherein the target sorting location is mapped to the damage status and list status. In some embodiments, different energy meters to be sorted need to be placed at corresponding target sorting locations during sorting. For example, an undamaged energy meter in the list is placed at target sorting location A; a damaged energy meter in the list is placed at target sorting location B; and a damaged energy meter not in the list is placed at target sorting location C. In some embodiments, the prompt message includes voice prompts. For example, during the sorting process, the system promptly determines the correspondence between the RFID tag of the energy meter currently taken by the user and its matrix coordinates, damage status, and list status, and queries the target sorting location corresponding to the energy meter based on its damage status and list status to prompt the user to place the energy meter at that target sorting location.

[0028] In some embodiments, the system further includes step S18 (not shown), whereby the sorting report is sent to the corresponding network device. In some embodiments, after all sorting is completed, the system sends the sorting report to the corresponding network device so that the corresponding user device can retrieve the sorting report from the network device. Through the technical solution of this embodiment, the sorting work can be delegated to county-level power supply companies. After sorting, the county-level power supply companies generate their own sorting reports. These reports are then uploaded to the corresponding network devices, and the sorted electricity meters are transported to the superior power supply company. When a power supply company above the county level needs to view the sorting reports of each county, it can send a viewing request to the network device through its user device. In this embodiment, by uploading the sorting reports to the network devices, systematic management of electricity meter recycling is achieved.
