[0044] Example 1

[0045] Reference Figure 1 , is an embodiment of the present invention, which provides a method for identifying the appearance of a fully compatible electric energy meter and a terminal, comprising:

[0046] S100: transporting the electric energy meter to a predetermined workstation, controlling the actuator according to a preset control instruction, and controlling the electric energy meter once;

[0047] S200: Each actuator is equipped with a signal device. When the primary control is completed, the actuator sends a confirmation signal to the electrical control system. The electrical control system performs logical judgment based on the received feedback signal and performs secondary control on the electric energy meter.

[0048] S300: Perform fault detection on the appearance of the electric energy meter after secondary control and record the fault information.

[0049] It should be noted that in the fully automatic calibration line of electricity meters, the existing appearance inspection of electricity meters can only calibrate one type of electricity meter. If the appearance inspection of all specifications of electricity meters is to be achieved, it is necessary to install special machines with different appearance inspection functions, which will occupy more space, greatly increase the construction cost, and reduce the utilization rate of special machines. In addition, this technical method cannot be implemented in a limited space, which wastes equipment resources. The present application, through the cooperation of compatible wiring and disconnection mechanisms and compatible trays, can realize the inspection of the appearance and LCD display of single-phase electricity meters, three-phase electricity meters, collection terminals and other electricity meters on the same special machine and upload the conclusions.

[0050] In the embodiment of the present application, before the electric energy meter is transported to a predetermined workstation, all components are located at initial positions.

[0051] In an optional embodiment, the components of the electric energy meter fully automatic calibration production line include at least a profile rack, a compatible pallet lifting mechanism, a compatible wire connection and disconnection mechanism, and a pallet conveyor line.

[0052] In an optional embodiment, a compatible connection and disconnection mechanism is installed on both sides of the profile frame, and the pallet conveyor line passes through the middle of the profile frame to convey the fully compatible pallet to the designated position; the connection and disconnection mechanism has two layers of meter socket placement library, each layer can be used to place any one of the single-phase meter socket, three-phase compatible meter socket, and terminal meter socket. The compatible connection and disconnection mechanisms on both sides achieve compatibility with electric energy meters and terminals by arranging different types of meter sockets.

[0053] In the embodiment of the present application, the actuator is controlled according to the preset control instruction, and the electric energy meter is controlled once, including: short-stroke cylinder action and long-stroke cylinder action;

[0054] The short-stroke cylinder extends according to the control command, lifts the electric energy meter to a fixed height, and provides signal feedback to the electrical control system;

[0055] After receiving the signal from the short-stroke cylinder, the electrical control system controls the long-stroke cylinder to extend, lifting the electric energy meter to the working position, thus completing one-step control.

[0056] After the long-stroke cylinder is in place, a signal is sent to the electrical control system again.

[0057] It should be noted that in the embodiment of the present application, the short-stroke cylinder action and the long-stroke cylinder action lift the electric energy meter to different heights to achieve appearance inspection of different types of electric energy meters; in the embodiment of the present application, the short-stroke cylinder can be controlled to detect three-phase electric energy meters and terminals, and the long-stroke cylinder can be controlled to detect single-phase electric energy meters; when the short-stroke cylinder is controlled to detect the three-phase electric energy meter and the terminal, the compatible tray used to place the electric energy meter needs to be adjusted to the working condition before inspection to adapt to the inspection of two different types of electric energy meters.

[0058] Furthermore, when controlling the short-stroke cylinder to detect two different types of electric energy meters, the detection of the two different types of electric energy meters must be completed from both sides of the height layer lifted by the short-stroke cylinder, wherein only one side of the height layer lifted by the short-stroke cylinder can detect one type of electric energy meter.

[0059] In an optional embodiment, the compatible pallet lifting mechanism is arranged in the middle position of the equipment frame and is provided with two cylinders with different strokes and a positioning assembly. The electrical control system controls the lifting action of the two cylinders to separate the pallet from the running pallet conveyor line and lift it to different working positions. The positioning assembly achieves precise positioning of the compatible pallet through the precise cooperation of the positioning pin and the positioning sleeve.

[0060] Exemplarily, a short-stroke cylinder of the compatible pallet lifting mechanism extends to lift the fully-compatible pallet, causing it to detach from the pallet conveyor line and reach the three-phase or terminal working position. The electrical control system then controls the second long-stroke cylinder to extend, and the fully-compatible pallet continues to rise to reach the working position of the single-phase electricity meter.

[0061] In the embodiment of the present application, the electrical control system performs logical judgment based on the received feedback signal, and performs secondary control on the electric energy meter, including:

[0062] The electrical control system receives the signal from the long-stroke cylinder. When the long-stroke cylinder lifts the electric energy meter to the working position, it controls the cylinder at the corresponding layer of the meter socket corresponding to the electric energy meter to extend, automatically connects the meter socket and the electric energy meter, and completes the secondary control.

[0063] In an optional embodiment, each layer of the compatible wiring connection and disconnection mechanism is equipped with an independent control cylinder. The electrical control system controls the extension and retraction of the cylinder, thereby driving the extension and retraction of the corresponding meter socket to achieve automatic wiring and disconnection of the electric energy meter.

[0064] In the embodiment of the present application, performing fault detection on the appearance of the electric energy meter after secondary control and recording fault information includes:

[0065] When the connection between the electric energy meter and the meter socket is completed, a completion signal is sent to the electrical control system, and the electrical control system sends the connection completion signal to the software system;

[0066] Based on the wiring completion information, the software system sends a power-on signal to the electric measuring device. After receiving the power-on command, the electric measuring device provides power to the electric energy meter connected thereto;

[0067] If the electric energy meter is successfully powered on, the camera recognition system is triggered to obtain an image of the contents of the electric energy meter screen and its upper surface area.

[0068] In an optional embodiment, the camera recognition system is equipped with industrial cameras distributed on the upper part of the equipment frame; 8 industrial cameras are arranged above the pallet conveyor line, 6 of which are used for the appearance recognition of single-phase electricity meters, and the other 2 are used for the appearance recognition of three-phase electricity meters and terminals. The field of view of the industrial cameras is fully capable of covering the upper surfaces of all electricity meters and terminals, and can take clear pictures. Taking into account the different heights and working positions of different meters, the industrial cameras have automatic zoom and distance change functions.

[0069] In an optional embodiment, the acquired image content may include the model / name, nameplate information, indicator light, and screen of the electric energy meter. Based on the acquired electric energy meter image, it is compared with a preset standard template to check whether the screen can be lit, whether the font displayed on the screen is clear and correct, and whether the screen has defects such as no display, missing segments, and damage.

[0070] In the embodiment of the present application, it also includes: according to the pixel distribution corresponding to the table type, accurately cropping the picture by pixel calculation to form the picture to be detected, and detecting the picture to be detected based on the detection model;

[0071] If there are missing characters or missing characters in the electricity meter, the electricity meter will be judged as unqualified. When all characters are recognized as qualified, the system will judge the electricity meter as qualified.

[0072] In the embodiment of the present application, performing fault detection on the appearance of the electric energy meter after secondary control and recording fault information also includes:

[0073] When the appearance inspection is completed, the software system sends a power-off signal to the electrical testing equipment. After receiving the power-off signal, the electrical testing equipment performs power-off and performs self-test;

[0074] If the electric measuring equipment confirms that the power failure is complete and the self-test is correct, the electric control system controls the cylinder to retract and remove the wires from the electric energy meter. After the cylinder is fully retracted, the removal action stops.

[0075] When the thread removal action stops, the electrical control system controls the short-stroke cylinder and the long-stroke cylinder to retract and descend to the initial position.

[0076] It should be noted that, in terms of model training, the detection model in the embodiment of the present application optimizes the character area perception model of text detection for automatic text box recognition in the appearance detection project of the electric energy meter; in order to adapt to the recognition requirements of nameplate information, model / name and other text information on the electric energy meter, the output layer channel of the character area perception model of text detection is changed from the original two heat maps to one heat map, and the interval between fonts is not considered for the time being. In addition, the subsequent traditional image processing is optimized, and a regional area screening mechanism is added to improve the detection accuracy. The spatial attention mechanism is introduced to solve the problem of a small number of text fonts that are difficult to detect, and to enhance the adaptability to different fonts and typesetting. The entire model is fine-tuned on the PyTorch framework to adapt to the data set of specific application scenarios, so as to train a better model. Finally, C++ is used for reasoning and deployed to the site to improve the efficiency of the reasoning process and ensure real-time and performance.

[0077] In terms of image detection, after the electric energy meter is powered on, the camera takes a picture. The image acquisition method with full appearance compatibility is changed from taking a picture of one meter to acquiring pictures of all the electric energy meters on the entire tray at one time. According to the pixel distribution corresponding to the meter type, the picture is accurately cropped through pixel calculation to form the picture to be tested. When testing through the detection model, if there is a missing character or a missing character, the system can automatically identify and judge the electric energy meter as unqualified. When all characters are recognized as qualified, the system will judge the electric energy meter as qualified.

[0078] The above is a schematic scheme of a method for identifying the appearance of a fully compatible electric energy meter and terminal in this embodiment. It should be noted that the technical scheme of the appearance identification system of the fully compatible electric energy meter and terminal and the technical scheme of the appearance identification method of the fully compatible electric energy meter and terminal described above belong to the same concept, and the details not described in detail in the technical scheme of the appearance identification system of the fully compatible electric energy meter and terminal in this embodiment can be referred to the description of the technical scheme of the appearance identification method of the fully compatible electric energy meter and terminal described above.

[0079] In this embodiment, a fully compatible electric energy meter and terminal appearance recognition system includes:

[0080] The primary control module is used to transport the electric energy meter to the predetermined workstation, control the actuator according to the preset control instructions, and perform primary control on the electric energy meter;

[0081] The secondary control module is used to equip each actuator with a signal device. When the primary control is completed, the actuator sends a confirmation signal to the electrical control system. The electrical control system performs logical judgment based on the received feedback signal and performs secondary control on the electric energy meter.

[0082] The fault detection module is used to detect faults on the appearance of the electric energy meter after secondary control and record fault information.

[0083] This embodiment further provides a computing device, which is applicable to the case where the appearance recognition method of the fully compatible electric energy meter and the terminal is used, and includes:

[0084] Memory and processor; the memory is used to store computer executable instructions, and the processor is used to execute computer executable instructions to implement the appearance recognition method of fully compatible electric energy meters and terminals as proposed in the above embodiment.

[0085] This embodiment further provides a storage medium on which a computer program is stored.

The technical details not described in detail in this embodiment can be referred to the above embodiment, and this embodiment has the same beneficial effects as the above embodiment.

[0087] Through the above description of the implementation methods, the technicians in the relevant field can clearly understand that the present invention can be implemented by means of software and necessary general hardware, and of course can also be implemented by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present invention is essentially or the part that contributes to the prior art can be embodied in the form of a software product, and the computer software product can be stored in a computer-readable storage medium, such as a computer floppy disk, read-only memory (ReadOnly, Memory, ROM), random access memory (RandomAccess Memory, RAM), flash memory (FLASH), hard disk or optical disk, etc., including a number of instructions for a computer device (which can be a personal computer, server, or network device, etc.) to perform the methods of various embodiments of the present invention.

[0088] Example 2

[0089] Reference Figure 1 , is an embodiment of the present invention. This embodiment is different from the first embodiment in that this embodiment takes the calibration of a single-phase electric energy meter as an example to verify the feasibility of the present invention.

[0090] In this embodiment, the fully compatible pallet is transported to the designated station of the appearance recognition machine through the pallet conveyor line, and then stops moving; the short-stroke cylinder in the compatible pallet lifting mechanism provides power to extend, lifts the fully compatible pallet to a fixed height, and detaches from the pallet conveyor line. After the electrical control system receives the short-stroke cylinder signal feedback, it notifies the control program to control the long-stroke cylinder to provide power to extend again, and continues to lift the fully compatible pallet. After the long-stroke cylinder stops moving, the electrical control system receives the signal feedback and executes the next step. During the cylinder lifting process of the compatible pallet lifting mechanism, the compatible pallet lifting mechanism contacts the compatible pallet, and its positioning component accurately positions the compatible pallet through the precise cooperation of the positioning pin and the positioning sleeve of the compatible pallet, thereby ensuring the uniqueness of the working position of the compatible pallet.

[0091] After the compatible tray lifting mechanism stops moving, the electrical control system makes a judgment through the signal feedback of the cylinder and the program setting, controls the compatible wiring mechanism to start moving, and the second-layer cylinder of the compatible wiring mechanism extends, so that the single-phase meter socket and the electric energy meter in the fully compatible tray complete the wiring action. According to the signal feedback of the cylinder of the compatible wiring mechanism, the electrical control system controls the electric measurement system to start powering on the electric energy meter and lighting up the LCD screen of the electric energy meter; after the electric measurement system completes the power-on action, the software system controls the camera recognition system to start taking pictures of the electric energy meter screen and the content of its upper surface area, and compares them with the preset standard template. If there are missing characters or missing characters in the single-phase electric energy meter, the single-phase electric energy meter is judged to be unqualified. When all characters are recognized as qualified, the system will judge the single-phase electric energy meter as qualified.

[0092] After the appearance inspection is completed, the software system controls the electric measuring system to cut off the power to the electric energy meter. After the electric measuring system is powered off and self-checked, the electrical control system controls the second-layer cylinder of the compatible wiring connection and disconnection mechanism to retract and disconnect the electric energy meter until the cylinder is fully retracted and the compatible wiring connection and disconnection mechanism stops moving. After the electrical control system receives the cylinder in-place signal feedback, the electrical control system controls the two cylinders of the compatible pallet lifting mechanism to retract and descend to the initial position, and the fully compatible pallet falls back on the pallet conveyor line. The electrical control system controls the pallet conveyor line to release the fully compatible pallet, completing the appearance inspection of the single-phase electric energy meter.

[0093] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
