[0026] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments. Example 1

[0027] like Figure 1-Figure 5 As shown, a meter installation and power connection training system includes a cabinet 1, a training module, and a detection module. The training module and the detection module are arranged on the cabinet 1.

[0028] In this embodiment, the cabinet 1 is formed by welding or bending shell plates and has a cubic or rectangular shape. The training module and the detection module are arranged inside. The positions and structures of the modules installed on the cabinet 1 are consistent with those of the actual distribution cabinet.

[0029] The lower front part of the cabinet 1 is divided into three sections: the left side is the electrical testing area, the center is the operation area, including: main power switch, indicator light, etc.; the right side is the wiring area including: wiring terminal group; the distribution lines and sensors are arranged at the back, which can detect the operator's operation of the cabinet 1.

[0030] The practical training module includes an electrical testing module, an operation module, and a wiring module. Operators can be trained on installing meters and connecting electricity through the electrical testing module, the operation module, and the wiring module.

[0031] The electrical test module includes a live power strip and an electrical test pen. Live power strip: simulates a real live circuit and is equipped with a standard three-hole socket.

[0032] In this embodiment, the three-hole socket complies with national standards (such as GB 2099.3) and includes three sockets for the live wire (L), the neutral wire (N), and the ground wire (PE). The sockets have built-in metal springs to ensure that the plugs are firmly in contact and have a protective door to prevent accidental touch (it can only be opened by inserting more than two poles simultaneously). Electricity test pen: The shell is made of insulating engineering plastic, with built-in photoelectric sensor and touch switch, and metal contacts at the tip of the pen.

[0033] In this embodiment, the tester uses gold-plated copper contacts to ensure conductive sensitivity and can detect AC and DC voltages between 12V and 250V. The contact area is ≤2mm², suitable for precise contact with wires or socket holes. Based on the principle of optocoupler isolation, the red LED flashes when voltage is detected (the frequency is proportional to the voltage). It complies with the IEC 61010-1 electrical safety standard and has a voltage rating of CATIII 600V. The tester is used to quickly determine circuit continuity and phase identification (live / neutral), and is particularly suitable for operation in confined spaces.

[0034] A signal acquisition unit is also installed inside the electrical test module. The signal acquisition unit is located behind the live power strip and can read the status of the test pen and output a digital signal. The contact between the test pen and the cabinet 1 and the live power strip is detected and recorded by the signal acquisition unit, and a signal is output.

[0035] In the electrical inspection module training, operators need to perform a three-step electrical inspection, specifically: 1. Touch the test pen to the live socket. If the socket is live, the photoelectric sensor on the top of the test pen will flash. 2. Touch the metal surface of cabinet 1 with an electric test pen to check whether cabinet 1 is charged; 3. Touch the test pen to the live socket again to check and confirm that there is no abnormality in the function of the test pen.

[0036] The signal acquisition unit can detect the operator's operation on the electrical detection module, confirm whether the detection is performed in accordance with the three-step electrical detection method, and transmit the results through electrical signals.

[0037] The operation module includes a main power switch, equipped with indicator lights, a relay unit, and a status detection sensor. Operators can only turn on the main power switch after completing electrical testing, live operation, and wiring. A switch detection sensor within the switch determines whether the operator has engaged in live operation and converts the detection result into an electrical signal for transmission.

[0038] The wiring module includes: a terminal block with 6 insulated terminals grouped by phase sequence and current and voltage circuits; voltage and current detection sensors, with a resistive voltage divider and a Hall current sensor behind each terminal group; and a signal collector that records and transmits the analog signal.

[0039] The operator can complete the wiring of the three-phase voltage and current circuits of the electricity meter on the terminal block; the system automatically detects whether the circuit connectivity and polarity are correct, and triggers an audible and visual alarm in case of error; after correct wiring, the signal collector can record the "wiring qualified" signal for transmission.

[0040] In this embodiment, the detection module includes a camera, a display device, and a computer. The camera can capture operator information and operations on the training module; the display device can be used for user interaction and display training content, assessment questions, and results; and the computer can receive signals from the camera and training module and transmit them to the display device.

[0041] In this embodiment, the cameras include a top front camera 11, a top rear camera 12, and a cabinet middle camera 13. Figure 1-4An extension frame is provided at the top center line of the cabinet 1 , and the top front camera 11 and the top rear camera 12 are both provided at both ends of the extension frame.

[0042] In this embodiment, the top front camera 11 and the top rear camera 12 are small spherical cameras. They can capture images from top to bottom around the cabinet 1. The images captured by the top front camera 11 and the top rear camera 12 are transmitted to a computer, which can then determine whether the operator is wearing a safety helmet and insulating gloves correctly and whether the trainee has completed a circumference inspection of the cabinet.

[0043] A middle-cabinet camera 13 is provided at the headquarters of the cabinet. In this embodiment, the middle-cabinet camera 13 is installed at the end of the arm 16, and the swing arm 16 can tilt downward. A middle-cabinet camera control box 14 is provided at one end of the swing arm 16 connected to the cabinet 1. The middle-cabinet camera control box 14 can control the swing arm 16, and then control the angle of the image acquired by the middle-cabinet camera 13, thereby realizing the horizontal 360° rotation and ±30° pitch of the middle-cabinet camera 13. When the operator is operating the training module, it can automatically align with the operating area and capture hand movements, tool usage and wiring details. The middle-cabinet camera control box 14 is connected to the computer and receives instructions and adjustments from the computer.

[0044] Reference Figure 1-3 The display device 15 can display information. The computer is connected to the display device 15. The data received by the computer can be processed by the computer and then displayed through the display device 15. The operator can control the display device 15 to adjust the computer. In this embodiment, the display device 15 includes a touch screen.

[0045] In this embodiment, the training module and the detection module are electrically connected, and the sensors, switches and sensor boards of each training module inside the cabinet 1 are connected to the wiring terminals on the back of the cabinet through shielded multi-core cables; the camera control box 14 in the middle of the cabinet is connected to the stepper motor, camera acquisition module and computer motherboard through a parallel bus; the camera video stream is imported into the computer through GigE Ethernet; the sensor signal is transmitted to the computer through the RS-485 bus or USB interface; the computer runs the training management software, receives various data and calls the AI algorithm for wear detection, action recognition, and wiring comparison; the final score and results are fed back to the operator and trainer through the display device 15.

[0046] In this embodiment, the training operations that the operator can perform include: 1. The operator needs to register or log in by setting up the display device 15.

[0047] 2. Record user data in the database in the computer.

[0048] 3. Determine whether the user is logged in. If not, return to step 2 and proceed to the next step after logging in.

[0049] 4. Top front camera 11 and top rear camera 12, located on the top front and rear of cabinet 1, respectively, are capable of capturing images of the operator's head and hands. The computer uses these images to identify whether the operator is properly wearing essential protective gear, such as insulating gloves, a hard hat, and safety clothing. If any equipment is detected as not being worn or improperly worn, the computer records this information and deducts points.

[0050] 5. When the operator performs an inspection around the cabinet 1, the top front camera 11 and the top rear camera 12 can cover the key viewing angles around the cabinet 1. In conjunction with the AI pedestrian trajectory tracking algorithm, it can be determined whether the trainee needs to patrol the cabinet from the front, side to the back in sequence according to the regulations; the system compares the trajectory with the preset "circle the cabinet" area model to determine whether the patrol path is complete. If it is not completed, the display device 15 can provide process prompts.

[0051] 6. Three-step electrical testing module, using a test pen, a live power strip, and a central cabinet camera 13. The specific testing method is as follows: Step 1: The trainee touches the test pen to the live power strip. If the live power strip is live, the bottom of the test pen flashes; the central cabinet camera 13 captures the flashing state and reports it. Step 2: The test pen is placed close to the metal surface of the cabinet. The detector measures zero potential and reports "cabinet no power." Step 3: Touch the live power strip again to ensure the test pen is functioning properly.

[0052] The computer can summarize whether the three operations conform to the time sequence and status results. If there is an interruption or the sequence is wrong, it will be judged as "irregular electrical testing" and a point deduction feedback will be given in the display device 15.

[0053] 7. Live operation monitoring: A main power switch and a status detection sensor are provided in the operation module. Before completing all the steps of installing the meter and connecting the power, the operator accidentally turns on the power switch. The top front camera 11 and the status sensor can capture the image and transmit it to the computer.

[0054] 8. Wiring simulation: Operators can simulate wiring through the wiring module, which can record the operator's operation records. The wiring module is consistent with the actual equipment that needs to be connected to electricity, and operators can simulate actual wiring operations on the wiring module.

[0055] 9. After wiring is complete, a power-on test is performed. The rotating camera 13 and the switch detection sensor inside the power switch confirm the power off status. The device simulation tester simulates a three-phase power output to verify the correct voltage, current, phase sequence, and phase of each phase terminal. If no abnormalities are found, the feedback is "Wiring Passed." The rotating camera continues to monitor the operating status of the energy meter simulator (rotating dial or LED indicator), detecting any looseness, short circuits, or abnormal vibration, and records and uploads the measured data (voltage, current, and meter reading).

[0056] 10. The top front camera 11 and the top rear camera 12 work in conjunction with the ground-pointing camera to use an image segmentation algorithm to identify debris (such as tools, paper scraps, water stains, etc.) on the ground in the operating area. If an obstacle that affects operational safety is detected, the computer deducts a certain number of points.

[0057] 11. The central cabinet camera control box 14 drives the central cabinet camera 13, enabling 13±30° pitch and 360° horizontal rotation, automatically scanning the wiring area in detail. The wiring process recognition model compares the student's wiring with the standard wiring template to determine whether the cable routing is clear, the binding is standardized, and the phase sequence labels are in place. If any non-standard wiring is found (such as entangled cables or misplaced labels), a screenshot of the incorrect location will be displayed on the display device 15 and points will be deducted.

[0058] 12. Report in the display device 15.

[0059] In step 5, the AI pedestrian trajectory tracking algorithm uses the target detection model to obtain the pedestrian's position, uses the Kalman filter to predict the pedestrian's motion state, and then matches the new detection frame with the existing trajectory based on the pedestrian's appearance characteristics, combining motion and appearance information. This allows for stable tracking of pedestrians in complex scenarios and completes trajectory recording. In this embodiment, the AI pedestrian trajectory can track the operator, ensuring that the operator can correctly circumvent the cabinet.

[0060] In this embodiment, the training structure can be uploaded to the cloud via a computer and can be downloaded and printed. Through multiple cameras and AI monitoring, illegal operations and protection deficiencies can be identified in real time, minimizing safety risks during training. In step 4, the top front camera 11 and the cabinet middle camera 13 can acquire images, transmit the images to the computer, and process the images through the computer.

[0061] In this embodiment, the processing process is: The captured image is positioned to confirm the position of the shoulder, elbow, wrist, and fingers. Based on the image changes, the operator's overall operating trajectory is determined to determine whether the operator's tool grip is standard and whether the steps are correct. The captured full-body image is verified and the operator's protective equipment (e.g., full headgear, insulating gloves, insulating boots, overalls) is inspected. Any non-compliance is marked as "non-compliant protection" and points are deducted.

[0062] Judge the operator's overall behavior and use behavior recognition technology to analyze, judge, and predict dangerous behavior categories such as falls and violent shaking.

[0063] The operator's position is determined based on their outline. The computer can recognize the operator's head, body, and hand images to confirm whether the operator is correctly wearing necessary protective equipment such as insulating gloves, hard hats, and safety clothing.

[0064] Through standardized practical operation processes and automatic computer scoring, subjective judgment errors are effectively avoided and training consistency is ensured; facial recognition login and automated assessment reduce management costs, and operators can interact through the display device 15; the operator's user experience is improved; the video and data of the entire training process can be stored and retrieved, facilitating subsequent retraining and quality review; the computer can perform behavioral analysis based on the screen, and can provide improvement and support for the operator's actual operation.

[0065] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art will appreciate that the present invention is not limited to the foregoing embodiments and that various modifications and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
