[0001] The present invention relates to the technical field of power consumption inspection, and particularly to a wiring state verification method, device, equipment and storage medium for a combined wiring box. Background Art

[0002] The function of the combined wiring box of the electric energy meter is to connect the secondary wires led out by the current / voltage transformer in series and parallel through the terminals of the wiring terminal of the combined wiring box and then connect them to the wiring terminals of the electric energy meter, so as to isolate the load and circuit of the power supply and provide a safe and reliable electrical connection for the electric energy meter.

[0003] Since there are many wiring terminals involved in the combined wiring box, it is very easy to misjudge the wiring state of the wiring box when the staff's attention is not concentrated or there is visual fatigue during long-term operation.

[0053] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0054] It should be noted that the current power consumption inspection mainly relies on expert experience for on-site identification. Such a method is time-consuming, laborious and material-consuming, and the inspection efficiency and accuracy are relatively low. Therefore, there is an urgent need for a portable active verification device for on-site power consumption inspection. In order to solve the problems of insufficient intelligent level of the existing power consumption inspection and inability to perform on-site active inspection, the problem to be solved by the present invention is to propose a lightweight combined junction box wiring verification method based on image classification. By collecting the wiring data images of the combined junction box, training a lightweight image classification model, and then deploying the algorithm model on the mobile terminal, the problem that the wiring of the junction box needs to rely on experts for on-site unified inspection is solved. By collecting the images or videos of the on-site wiring situation, the correctness of the wiring is judged. For specific reference, see the following content.

[0055] Please refer to Figure 1 , Figure 1The figure is a flowchart of a method for verifying the wiring status of a combined junction box in an embodiment of the present invention. This method can be applied to both terminals and servers. In this embodiment, taking the application to a terminal as an example, the terminal can specifically be a desktop terminal or a mobile terminal, and the mobile terminal can specifically be at least one of a mobile phone, a tablet computer, a laptop computer, etc. The server can be implemented by an independent server or a server cluster composed of multiple servers. As Figure 1 The method shown includes the following steps:

[0056] 101. Obtain a wiring image of the junction box to be verified, where the junction box to be verified includes a plurality of short-circuiting pieces and wiring terminals;

[0057] The present invention intends to perform power consumption inspection of the combined junction box in a target detection-based manner. In this way, it is necessary to identify the wiring positions in the junction box and the positions of the short-circuiting pieces, and judge the wiring condition of the junction box according to the relative positions of the wiring positions and the short-circuiting pieces. The combined junction box is divided into four wiring areas according to colors (yellow, green, red, blue) as shown in Fig. 2(a). Fig. 2(a) is a schematic diagram of the wiring of a combined junction box in an embodiment of the present invention. Among them, the first three areas include two wiring blocks for voltage and current, and the last area is a voltage wiring block. The upper and lower wiring terminals in each column of the junction box are electrically connected. For voltage wiring, when the terminal is located below, the corresponding phase is open; for current wiring, when the short-circuiting piece is closed, the two connected terminals are short-circuited, and thus there is no current in the secondary circuit, which is convenient for maintenance and repair. Reference can also be made to Fig. 2(b). Fig. 2(b) is a schematic diagram of different switch positions of a combined junction box in an embodiment of the present invention, specifically showing the arrangement of the wiring terminals and short-circuiting pieces in the current wiring area, as well as different switch positions of the short-circuiting pieces, including the upper row of wiring terminals t1, t2, and t3, the lower row of wiring terminals d1, d2, and d3, the short-circuiting piece S1, and the short-circuiting piece S2. In Fig. 2(b), the switch position (i) is that both the short-circuiting piece S1 and the short-circuiting piece S2 are in the open state; in Fig. 2(b), the switch position (ii) is that both the short-circuiting piece S1 and the short-circuiting piece S2 are in the closed state; in Fig. 2(b), the switch position (iii) is that the short-circuiting piece S1 is in the closed state and the short-circuiting piece S2 is in the open state; in Fig. 2(b), the switch position (iv) is that the short-circuiting piece S2 is in the closed state and the short-circuiting piece S1 is in the open state.

[0058] It should be noted that in this application, the wiring condition of the junction box is verified by combining the image recognition method. First, an image needs to be obtained. This image includes a plurality of short-circuiting pieces and wiring terminals. The image style can refer to Fig. 2(a). The wiring terminals and short-circuiting pieces of the junction box are recognized by using this image, and the wiring status verification is completed in combination with the subsequent rules. The way to obtain the image can be that the user uploads a historical image, or the user takes a real-time image on-site, which is not limited here.

[0059] In a feasible implementation, whether it is a historical image or a real-time image, in order to ensure the integrity and standardization of each detection target during object detection, when taking the above-mentioned images, a reference line can be output to assist the user in taking a complete and standardized image, so as to obtain an example as shown in Fig. 2(a). Therefore, before obtaining the wiring image of the junction box to be verified, it further includes: when receiving a photographing request from a preset client, outputting a preset reference line for photographing the junction box to the client, and the reference line is used to prompt the user with the standard photographing template of the junction box to be verified.

[0060] It can be understood that different shooting states will affect the imaging result. Therefore, in order to standardize the imaging result and make it reach the best imaging result as shown in Fig. 2(a), when the present application receives a photographing request, it will output a reference line for photographing the junction box to the client, providing a standardized standard photographing template to assist the user. Refer to Figure 2c , Fig. 2(c) is a schematic diagram of a reference line for photographing a combined junction box in an embodiment of the present invention. The reference line is designed according to the four voltage connection blocks and three current connection blocks of the junction box, allowing the user to frame the junction box to be photographed within the range of this reference line to ensure a standardized imaging result.

[0061] 102. Detect the wiring image by using a pre-trained object detection model to obtain the detection result of the current wiring of the junction box to be verified. The detection result includes the wiring positions of each wiring and the short-circuit positions of each short-circuit piece. The object detection model is used to identify and classify the wiring positions and short-circuit pieces in the wiring image;

[0062] Further, visual recognition technology is used for object detection to train an object detection model that can recognize the wiring positions and the positions of the jumper plates. Exemplarily, to train the object detection model, data collection and annotation are required: by collecting a large number of wiring pictures of the combined junction box, the positions of the wiring and the switches in the wiring junction box are annotated. Among them, Fig. 2(d) is a schematic diagram of an annotation method for the image data of a combined junction box in an embodiment of the present invention, where multiple wiring positions and jumper plates are annotated. It can be understood that a large number of image samples will be collected, and the wiring conditions of each image sample may be the same or different, and the annotation results will also be different. It may be the situation in Fig. 2(a) or a situation different from Fig. 2(a). The annotation label for the wiring position is the terminal number corresponding to each wiring position, and the annotation label for the jumper plate is the number of the jumper plate. The numbers of different terminals are different, and the same is true for the jumper plates. The terminals and the jumper plates are distinguished by numbers. For example, the numbers of the terminals can be the numbers t1 to t3 and d1 to d3 shown in Fig. 2(b), and the numbers of the jumper plates can be S1 to S2. Then, the training of the model begins: the Yolo-v5 model is used to train the annotated model so that the model can recognize the wiring positions and switches in the image. Among them, the classification results at least include the wiring positions and the positions of the jumper plates of each jumper plate. The wiring position is used to indicate the wired position, and it can be obtained which terminal has been wired for the wiring position, and which jumper plate it is. And, combined with the image coordinate system, the coordinates of each wiring position and the coordinates of the jumper plate position are obtained to obtain the relative position relationship in the same coordinate system for subsequent wiring verification. Based on the image coordinate system, the pixel coordinates of each wiring position and the jumper plate are obtained, and the pixel coordinates include the horizontal coordinate and the vertical coordinate; the object detection model can be the Yolo-v5 model.

[0063] After obtaining the object detection model, the newly collected wiring box images can be recognized and classified by using this object detection model. The post-processing of the recognition results includes judging the relevant positions of the boundary positions and the switch positions of the output results of the model according to the set specifications. Among them, the set specifications include the shorting plate state judgment rule and the wiring rule. The specific design concept is as follows:

[0064] When the combined junction box is working properly, the following relationships should be satisfied between the wiring and the terminals:

[0065] (1) In the voltage wiring area, the shorting plate should be in the closed position;

[0066] (2) In the current wiring area, when all the shorting plates are in the open position, the wiring of the upper and lower area terminals should be connected to the terminals in the same column; when there is exactly one shorting plate in the closed state, the two terminals in the closed position cannot be wired at the same time; when all the shorting plates are in the closed position, only terminals 1 and 3 can be connected above and below.

[0067] It can be seen that different connection specifications exist for different shorting strip states in the current connection area. Therefore, the connection verification of this application first determines the state of the shorting strip and then verifies the connection position to ensure the accuracy of the verification result.

[0068] (2.1) Referring to Fig. 2(b), when both shorting strips S1 and S2 are in the open state (case (i) in Fig. 2(b)), there is:

[0069]

[0070] When both shorting strips S1 and S2 are in the open state, the horizontal coordinate of shorting strip S1 is less than the horizontal coordinate of shorting strip S2 At this time, the upper and lower two-way terminals of the connection should be in the same column position, that is, connecting t1d1 and t2d2, t1d1 and t3d3, or t2d2 and t3d3. Therefore, the next step is how to determine that the connections of the upper and lower two-way terminals are on the same column. Here, H represents the horizontal coordinate.

[0071] In the most ideal state, when the vertical coordinates of two lines are equal, it is considered that they are in the same column, but this also results in a very small fault tolerance rate of the system. Therefore, this application uses the relative position method to make the judgment, that is, when both lines are on one side of the shorting strip, it is considered that the two lines are connected to the connection terminals in the same column. The specific method is as follows:

[0072] ① When the connection position is t1d1 and t2d2, it should satisfy:

[0073]

[0074] ② When the connection position is t1d1 and t3d3, it should satisfy:

[0075]

[0076] ③ When the connection position is t2d2 and t3d3, it should satisfy:

[0077]

[0078] Here, H represents the horizontal coordinate.

[0079] (2.2) Referring to Fig. 2(b), when both shorting strips S1 and S2 are in the closed position (case (ii) shown in Fig. 2(b)), there is:

[0080]

[0081] At this time, when both shorting strips S1 and S2 are in the closed position, the horizontal coordinate of shorting strip S1 Greater than the horizontal coordinate of the shorting piece S2 If the connection positions are only t1d1 and t3d3, the following conditions should be met:

[0082]

[0083] (2.3) Referring to Fig. 2(b), when the shorting piece S1 is closed and the shorting piece S2 is open (the situation (iii) shown in Fig. 2(b)), we have:

[0084]

[0085] Then t1d1 must be connected, and any one of the others, t2d2, t2d3, t3d2, t3d3, can be selected for connection.

[0086] (2.4) Referring to Fig. 2(b), similarly, when S2 is closed and S1 is open (the situation (iv) shown in Fig. 2(d)), we have:

[0087]

[0088] Then t3d3 must be connected, and any one set of connections from the others, t1d1, t1d2, t2d1, t2d2, can be selected.

[0089] After determining the above rules, subsequent detection applications can be carried out.

[0090] 103. Use the position of the shorting piece and the preset judgment rules for the state of the shorting piece to determine the state of the target shorting piece, where the state of the shorting piece is used to reflect the on / off state of the shorting piece;

[0091] After obtaining the position of the shorting piece, first, the state of the shorting piece can be confirmed using the judgment rules for the state of the shorting piece. The state of the shorting piece is used to reflect the on / off state of the shorting piece. For example, whether the shorting piece is in a closed or open state. Among them, the judgment rules are set based on the relative position relationship between the shorting pieces, and the state of the target shorting piece is determined through the relative position relationship between the two shorting pieces.

[0092] Among them, the judgment rules for the state of the shorting piece are determined according to the change in the relative position relationship between the two shorting pieces under different switch positions. As can be seen from Fig. 2(b), the position relationship between the two in the horizontal direction changes under different switch positions. Therefore, the horizontal coordinate is used to judge the state of the shorting piece. Specifically, the position of the shorting piece includes the first horizontal coordinate H S1 and the first vertical coordinate V S1 , as well as the second horizontal coordinate H S2 and the second vertical coordinate V S2 of the second shorting piece S2, and the first vertical coordinate V S1 of the first shorting pieceless than the second vertical coordinate V of the second jumper S2 , step 103 includes:

[0093] A01. If the first horizontal coordinate H S1 is less than the second horizontal coordinate H S2 , the target jumper state is that both the first jumper and the second jumper are in the open state;

[0094] A02. If the first horizontal coordinate H S1 is greater than the second horizontal coordinate H S2 , the target jumper state is that both the first jumper and the second jumper are in the closed state;

[0095] A03. If the first horizontal coordinate H S1 is equal to the second horizontal coordinate H S2 , the target jumper state is that one of the first jumper and the second jumper is in the closed state and the other is in the open state.

[0096] 104. Perform wiring verification according to the target jumper state, the corresponding relationship between the preset jumper state and the wiring rule, the jumper position, and the wiring position, and determine the target wiring state of the junction box to be verified, where the wiring state is used to reflect whether the wiring position is correct;

[0097] After determining the target jumper state, it is possible to further determine whether the wiring situation in this state meets the requirements. Based on the above design concept, the corresponding relationship between the jumper state and the wiring rule is pre-designed. By counting the relationship between the compliant jumper state and the wiring situation, the corresponding relationship is sorted out. The corresponding relationship includes the wiring rules when both jumpers are closed, the wiring rules when both jumpers are open, the wiring rules when one jumper is closed and the other is open, and so on.

[0098] Further, step 104 may include:

[0099] B01. Obtain the target wiring rule in the target jumper state according to the corresponding relationship between the preset jumper state and the wiring rule and the target jumper state;

[0100] B02. Perform wiring verification according to the target wiring rule, the jumper position, and the wiring position, and determine the target wiring state of the junction box to be verified.

[0101] It can be understood that after knowing the state of the target jumper, the target wiring rule corresponding to the target jumper state can be found from the wiring rules corresponding to the states of numerous jumpers, so as to further verify the wiring position. According to the target wiring rule, the jumper position, and the wiring position, wiring verification is performed to determine the target wiring state of the junction box to be verified, such as correct or incorrect wiring.

[0102] In a feasible implementation manner, if the state of the target jumper is that both the first jumper and the second jumper are in the open state, then the wiring verification according to the target wiring rule, the jumper position, and the wiring position to determine the target wiring state of the junction box to be verified includes:

[0103] C01. When the wiring positions are t1d1 and t2d2, and the wiring positions satisfy: Then it is determined that the target wiring state of the junction box to be verified is the correct state;

[0104] C02. When the wiring positions are t1d1 and t3d3, and the wiring positions satisfy: Then it is determined that the target wiring state of the junction box to be verified is the correct state;
