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

[0027] like Figures 1-5 As shown, a meter installation and connection training system includes a cabinet 1, a training module, and a testing module. The training module and the testing module are installed on the cabinet 1.

[0028] In this embodiment, the cabinet 1 is formed by welding or bending shell plates, and has a cubic or cuboid shape. The interior contains training modules and testing modules. The various modules installed on the cabinet 1 are consistent in position and structure with the actual power distribution cabinet.

[0029] The lower front of cabinet 1 is divided into three sections: the left side is the voltage testing area, the center is the operation area, including the main power switch, indicator lights, etc.; the right side is the wiring area, including the terminal block; and the back is where the power distribution lines and sensors are arranged to detect the operator's operation of cabinet 1.

[0030] The training modules include a voltage testing module, an operation module, and a wiring module. Operators can be trained to install meters and connect electricity through these modules.

[0031] The voltage testing module includes a live power strip and a voltage tester. The live power strip simulates a real live circuit and also features a standard three-prong socket.

[0032] In this embodiment, the three-hole socket conforms to national standards (such as GB 2099.3) and includes three holes: live wire (L), neutral wire (N), and ground wire (PE). The holes have built-in metal springs to ensure a firm contact of the plug and are equipped with a safety shutter to prevent accidental contact (it can only be opened when two or more poles are inserted simultaneously). Test pen: The outer shell is made of insulating engineering plastic, with a built-in photoelectric sensor and touch switch, and metal contacts at the tip.

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

[0034] The voltage testing module also includes a signal acquisition unit located behind the live power strip. This unit can read the status of the voltage tester and output digital signals. The contact status between the voltage tester and cabinet 1, as well as the live power strip, can be detected, recorded, and output as signals by the signal acquisition unit.

[0035] In the voltage testing module training, operators need to perform a three-step voltage testing procedure, specifically: 1. Touch the power strip with the test pen. If the power strip is energized, the photoelectric sensor at the top of the test pen will flash. 2. Touch the metal surface of cabinet 1 with a voltage tester to check if cabinet 1 is energized; 3. Touch the test pen to the live power strip again to check and confirm that the test pen is functioning normally.

[0036] The signal acquisition unit can detect the operator's operation of the voltage detection module, confirm whether the three-step voltage detection method is followed, and transmit the results through electrical signals.

[0037] The operating module includes a main power switch and is equipped with indicator lights, relay units, and status detection sensors. Operators can only turn on the main power switch after completing the voltage testing, live-line operation, and wiring procedures. An internal switch detection sensor determines whether the operator has performed a "live-line 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 according to phase sequence and current and voltage circuits; voltage and current detection sensors, with a resistive voltage divider and Hall current sensor behind each terminal group; and a signal acquisition unit that records and transmits analog signals.

[0039] Operators can complete the wiring of the three-phase voltage and current circuits of the energy meter on the terminal block; the system automatically detects whether the circuit continuity and polarity are correct, and triggers an audible and visual alarm when there is an error; after correct wiring, the signal acquisition unit can record and transmit the "wiring qualified" signal.

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

[0041] In this embodiment, the cameras include a top front camera 11, a top rear camera 12, and a cabinet center camera 13. (Refer to...) Figure 1-4An extension frame is installed through the center line of the top of cabinet 1, and the front top camera 11 and the rear top camera 12 are both equipped with extension frames at both ends.

[0042] In this embodiment, the top front camera 11 and the top rear camera 12 are small spherical cameras. They can identify the scene around the cabinet 1 from top to bottom. The scenes detected by the top front camera 11 and the top rear camera 12 can be transmitted to the computer, which can identify whether the operator is wearing a safety helmet and insulated gloves correctly, and whether the trainee has patrolled and inspected the cabinet.

[0043] A central camera 13 is installed at the head of the cabinet. In this embodiment, the central camera 13 is mounted at the end of the arm 16, which can tilt downwards. A control box 14 for the central camera 13 is installed at the end of the arm 16 connected to the cabinet 1. The control box 14 controls the arm 16, thereby controlling the angle at which the central camera 13 acquires images, enabling 360° horizontal rotation and ±30° tilt of the central camera 13. It can automatically align with the operating area and capture hand movements, tool usage, and wiring details when operators are performing training module operations. The control box 14 is connected to a computer and receives instructions from the computer for adjustment.

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

[0045] In this embodiment, the training module and the testing module are electrically connected. Inside the cabinet 1, the sensors, switches, and sensor boards of each training module are connected to the wiring terminals on the back of the cabinet via shielded multi-core cables. The camera control box 14 in the middle of the cabinet is connected to the stepper motor, the camera acquisition module, and the computer motherboard via a parallel bus. The camera video stream is fed into the computer via GigE Ethernet. The sensor signals are transmitted to the computer via RS-485 bus or USB interface. The computer runs training management software, receives data from various sources, and calls AI algorithms to perform wearable 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 operators can perform include: 1. Operators need to register or log in through the display device 15.

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

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

[0049] 4. Top front camera 11 and top rear camera 12 are respectively installed on the top front and rear sides of cabinet 1, and can detect images of the operator's head and hands. The computer uses the detected images to identify whether the operator is correctly wearing necessary protective equipment such as insulating gloves, safety helmets, and safety clothing. When a situation is detected where the equipment is not worn or worn improperly, the computer can record it and deduct points.

[0050] 5. When the operator performs a circumference inspection of cabinet 1, the top front camera 11 and top rear camera 12 can cover the key viewpoints around cabinet 1. With the help of the AI ​​pedestrian trajectory tracking algorithm, the system can determine whether the trainee needs to patrol around the cabinet in sequence from the front and side to the back according to the procedure. The system compares the trajectory with the preset "circumference of cabinet" area model to determine whether the patrol path is complete. If it is not completed, the system can provide a process prompt on the display device 15.

[0051] 6. The three-step voltage testing module uses a voltage tester, a live power strip, and a camera 13 in the middle of the cabinet for testing. The specific testing method is as follows: Step 1: The trainee touches the live power strip with the voltage tester. If the power strip is live, the bottom of the voltage tester will flash; the camera 13 in the middle of the cabinet will capture the flashing and report it; Step 2: The trainee places the voltage tester close to the metal surface of the cabinet. The detector measures zero potential and reports "No power in the cabinet"; Step 3: The trainee touches the live power strip again to ensure that the voltage tester is functioning properly.

[0052] The computer can summarize whether the three operations are in the correct time sequence and state results. If there is an interruption or sequence error, it will be judged as "non-standard power testing" and points will be deducted in the display device 15.

[0053] 7. Live operation monitoring: The operation module is equipped with a main power switch and a status detection sensor. If the operator accidentally turns on the power switch before all the meter installation and power connection steps are completed, 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 using the wiring module, which records their actions. The wiring module matches the actual equipment requiring power, allowing operators to simulate real-world wiring operations.

[0055] 9. After wiring is completed, a power-on test is performed. The rotating camera 13 and the switch detection sensor inside the power switch can confirm the power is off. The equipment simulation tester verifies the correctness of the voltage, current, phase sequence, and phase of each phase terminal by simulating three-phase power output. If no abnormalities are found, it will report "wiring qualified". The rotating camera continues to monitor the operation status of the energy meter simulator (rotary dial or LED indicator), checking for looseness, short circuits, or abnormal vibrations, and records and uploads the measurement data (voltage, current, meter reading).

[0056] 10. The top front camera 11 and the top rear camera 12, together with the ground-pointing camera, use image segmentation algorithms to identify debris (such as tools, paper scraps, water stains, etc.) on the ground in the operating area; if an obstacle affecting the safety of operation is detected, the computer will deduct a certain number of points.

[0057] 11. Driven by the central camera control box 14, the central camera 13 can achieve ±30° tilt and 360° horizontal rotation, automatically scanning the wiring area in detail. The wiring process identification model compares the trainee'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 non-standard wiring is found (such as cable tangling or misaligned labels), a screenshot of the incorrect part is displayed on the display device 15 and points are deducted.

[0058] 12. Reporting is conducted in display device 15.

[0059] In step 5, the AI ​​pedestrian trajectory tracking algorithm obtains the pedestrian's position through a target detection model, predicts the motion state using Kalman filtering, and then matches the new detection box with the existing trajectory based on the pedestrian's appearance features and the motion and appearance information. This allows for stable tracking of pedestrians in complex scenes and completes trajectory recording. In this embodiment, the AI ​​pedestrian trajectory can track the operator, ensuring that the operator can correctly circle the cabinet.

[0060] In this embodiment, the training structure can be uploaded to the cloud via computer and can also be downloaded and printed. Multiple cameras and AI monitoring can identify violations and security gaps in real time, minimizing security risks during training. In step 4, the top front camera 11 and the cabinet middle camera 13 can acquire images and transmit them to the computer for processing.

[0061] In this embodiment, the processing procedure is as follows: The acquired images are used to locate and confirm the positions of the shoulders, elbows, wrists, and fingers. Changes in the images are used to determine the operator's overall operational trajectory, assessing whether the operator's grip on the tools is standard and whether the steps performed are correct. The acquired full-body images are then reviewed, and the operator's protective equipment (e.g., full-face helmet, insulated gloves, insulated boots, work clothes) is inspected. Any non-compliance is marked as "non-compliant protection" and points are deducted.

[0062] The system assesses the overall behavior of operators and uses behavior recognition technology to analyze, judge, and predict dangerous behaviors such as falls and violent shaking.

[0063] The computer determines the operator's location based on their silhouette. It can recognize the operator's head, body, and hand images to confirm whether the operator is correctly wearing essential protective equipment such as insulated gloves, a safety helmet, and safety clothing.

[0064] Standardized practical procedures and automatic computer scoring effectively avoid subjective judgment errors and ensure training consistency; facial recognition login and automated assessment reduce management costs, and operators can interact through the display device 15; improving the user experience for operators; all training videos and data can be stored and retrieved, facilitating subsequent retraining and quality audits; the computer can perform behavioral analysis based on the screen, providing improvement and support for the operators' actual operations.

[0065] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model.
