Technical Field

[0001] The invention relates to the technical field of electric power training, and in particular to a dual power automatic transfer switch training and assessment device. Background Art

[0002] Automatic Transfer Switching Equipment (ATSE) is widely used in important places such as hospitals, airports, transportation, fire protection, and server rooms. It ensures that when the main power is cut off or other faults occur, the backup power supply can be put into use in time to maintain normal power supply. With the development of technology, the application scope of ATSE is becoming increasingly wide, and the requirements for its stability and intelligence are also increasing. In order to ensure that relevant personnel can master the operation and maintenance skills of ATSE, the market has put forward higher requirements for ATSE training equipment. However, there is still a lack of professional training equipment in the market.

[0003] The methods commonly used in related technologies to solve the practical training problems of dual power automatic transfer switches mainly include: one is to let students understand the basic principles and operating procedures of ATSE through theoretical explanations and paper materials; the other is to use actual ATSE equipment to allow students to perform practical operations in a real environment.

[0004] Although the former can convey basic knowledge quickly, due to the lack of intuitive experience, it is difficult for trainees to understand the complex working principles and apply the knowledge learned in actual work; although the latter provides practical opportunities, it cannot be widely used in general training due to the certain risks and high costs of real equipment operation. Therefore, the current practical training effect on ATSE equipment is not ideal, and the assessment method is difficult to effectively evaluate the actual operation ability of trainees.

This evaluation mechanism helps trainees to form correct operation habits, improve operation skills, and ensure that they can complete tasks safely and effectively in a real working environment.

[0016] In some embodiments, the information collection terminal is also used to obtain the switch displacement information of the dual-way switch simulation unit, and determine the parameter setting evaluation result according to the switch displacement information, the switch setting parameters and the correct answer to the switch parameters.

This process ensures the accuracy of the trainees when setting the ATSE parameters, improves the quality of the assessment of the trainees' operating skills, and enables the trainees to make correct decisions in actual operations.

[0018] In some embodiments, the training and assessment module also includes a safety failure simulation unit, which is used to simulate equipment safety failures and issue safety warnings. The equipment operation control unit is also used to receive the trainee's response to the safety warning and generate safety response information. The information collection terminal is also used to determine whether the trainee's response operation is qualified based on the safety response information.

[0019] The technical solution of this embodiment is adopted, through the combination of the safety failure simulation unit and the equipment operation control unit, to simulate the equipment safety failure and issue an alarm, and to assess the trainee's ability to respond to the safety alarm. The information collection terminal records the trainee's safety response operation, and the server determines whether the trainee's response is qualified based on this.

This identity authentication mechanism prevents cheating such as taking the exam for someone else, ensures the authenticity of the assessment results, and also provides an accurate personal identification for the trainee's training record.

[0022] In some embodiments, the dual power automatic transfer switch training and assessment equipment also includes a load simulation unit, which is used to simulate the power load and provide the load response status of the power load during the switching process of the two power simulation units.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. The embodiments of the present invention are described in detail below.

[0033] The embodiment of the present invention provides a dual power automatic transfer switch training and assessment device, such as Figure 1 and Figure 2 As shown, it includes a two-way power supply simulation unit 1, a power supply fault simulation unit 2, a power supply monitoring unit 3, an equipment operation control unit 4, a dual-way switch simulation unit 5 and a training and assessment module 6.

[0034] The dual-power supply simulation unit 1 can be used to simulate the main power supply and the backup power supply in an actual power supply to provide a real dual-power supply operation environment.

[0035] The power failure simulation unit 2 is used to control the two-way power supply simulation unit 1 to generate a set power failure signal to simulate a power failure of the two-way power supply simulation unit 1 .

[0036] Specifically, the power supply fault simulation unit 2 can adjust and control the voltage loop in the two-way power supply simulation unit 1 to generate a set power supply fault signal. The power supply fault simulation unit 2 uses a built-in software program to adjust the output characteristics of the simulated power supply according to the preset fault type and parameters, such as voltage value, duration and phase state, so as to simulate various fault scenarios that may be encountered in the power system, such as power failures such as loss of voltage, overvoltage, undervoltage or phase loss of the main power supply. In this way, the power supply fault simulation unit 2 can not only simulate the fault of a single power supply, but also generate different fault signals on the two-way power supply simulation unit 1 simultaneously or sequentially to create complex fault scenarios and provide students with a comprehensive practical training experience. This ability to simulate faults enables students to learn and practice how to identify, respond to and handle various power supply abnormalities in a safe and controllable environment, thereby improving their proficiency in the operation of dual power automatic transfer switches (ATSE) equipment and their emergency response capabilities for fault handling.

[0037] The power monitoring unit 3 is used to monitor the power failure signal and obtain the power status monitoring information of the two-way power simulation unit 1.

[0038] Specifically, the power monitoring unit 3 can collect key power parameters such as voltage, current, frequency, etc. of the two power simulation units 1 in real time through relevant sensors. These sensors are precisely installed on the incoming and outgoing lines of the analog power supply to ensure that any slight power changes can be captured. The microcontroller or digital signal processor (DSP) inside the power monitoring unit 3 receives the analog signal from the sensor, converts it into a digital signal, and performs necessary signal conditioning and filtering to eliminate noise and interference. Subsequently, these digital signals are further analyzed to identify and record the power supply status, including whether there are faults such as overvoltage, undervoltage, loss of voltage or phase loss.

[0039] The device operation control unit 4 is used to receive switch setting parameters set by the trainee.

[0040] Among them, the equipment operation control unit 4 has a human-computer interaction interface in the practical training and assessment equipment, providing an intuitive operation panel and a user-friendly graphical user interface (GUI), so that trainees can easily input and adjust the operating parameters of the ATSE. The equipment operation control unit 4 can be equipped with a touch screen, buttons, knobs or other input devices, allowing trainees to set key operating parameters such as over-voltage and under-voltage switching thresholds, switching delays, priorities, etc. according to the requirements of the practical training tasks. After the trainees set these parameters, they will be converted into control signals and sent to the dual-way switch simulation unit 5 to guide it to perform the corresponding automatic or manual switching actions. At the same time, the equipment operation control unit 4 also has real-time display and feedback functions, allowing trainees to monitor the current status and response results of the ATSE, ensuring that the trainees' operating intentions are accurately executed, and providing an important basis for subsequent evaluation and learning.

[0041] The dual-way switch simulation unit 5 is used to control the two-way power supply simulation unit 1 to switch according to the power supply status monitoring information and the switch setting parameters.

[0042] Specifically, the dual-way switch simulation unit 5 accurately controls the switching between the two power supply simulation units 1 by receiving the real-time power supply status monitoring information provided by the power supply monitoring unit 3, such as parameters such as voltage, current and frequency, and the switch setting parameters input by the trainee through the equipment operation control unit 4, such as over-voltage and under-voltage thresholds and switching delay time. When the monitored power supply parameters exceed the preset threshold or meet specific conditions, the dual-way switch simulation unit 5 will automatically trigger the switching logic and seamlessly switch between the two power supplies to ensure the continuity and stability of the power supply. At the same time, the dual-way switch simulation unit 5 can also simulate manual switching operations, allowing trainees to practice manual intervention processes in specific situations, thereby comprehensively training trainees' mastery of ATSE operations and their ability to respond to emergencies.

[0043] The training assessment module 6 is used to determine the training assessment evaluation result of the trainee according to the preset correct answer of the switch parameter and the switch setting parameter.

[0044] Specifically, the practical training and assessment module 6 can automatically compare the switch setting parameters entered by the trainee in the equipment operation control unit 4 with the preset correct answers through the built-in evaluation algorithm and standard answer library. The practical training and assessment module 6 monitors the trainee's operation process in real time, records each parameter setting and switching action, and then evaluates the trainee's response time, parameter accuracy and fault handling strategy based on preset performance indicators and operating specifications. By analyzing whether the trainee's operation complies with best practices and safety standards, the practical training and assessment module 6 can objectively evaluate the trainee's performance and generate a detailed assessment report, including operation accuracy, fault handling efficiency and overall performance score. In addition, the module can also provide feedback and suggestions to help trainees identify deficiencies and room for improvement in operation, thereby promoting the improvement of trainees' skills and consolidation of knowledge.

[0045] With the above design, this embodiment simulates the actual dual power supply environment, so that trainees can experience and learn how to handle various complex power supply failures in a controlled risk environment, thereby enhancing their understanding and mastery of ATSE operations. The power supply failure simulation unit 2 can generate accurate fault signals and simulate real power supply abnormalities, such as overvoltage, undervoltage, loss of voltage and phase loss, providing trainees with comprehensive fault handling training. At the same time, the power supply monitoring unit 3 monitors the power supply status in real time to ensure that trainees can make decisions based on accurate data. The combined use of the equipment operation control unit 4 and the dual-way switch simulation unit 5 allows trainees to practice the parameter setting and switching operation of ATSE and deepen their understanding of the working principle of ATSE. The automatic evaluation function of the training assessment module 6 not only improves the objectivity and accuracy of the assessment, but also provides the coach with quantitative evaluation data, which helps to improve the teaching methods and content in a targeted manner. In addition, this embodiment also helps to reduce the operating risks of real equipment in actual training, reduces training costs, improves training efficiency, and can effectively evaluate the actual operation capabilities of trainees.

[0046] The embodiment of the present invention provides an efficient, safe and practical training platform for distribution system operation and maintenance personnel by combining simulated training with intelligent assessment, which is of great significance for improving the reliability and safety of the power system.

[0047] In some embodiments, the equipment operation control unit 4 can also be used by trainees to control equipment operation. As a practical training and assessment device, the equipment operation control unit 4 can provide trainees with an intuitive operation platform, enabling them to directly input and adjust the operating parameters of the ATSE, such as setting over-voltage and under-voltage thresholds, switching delays, and other related operation settings. This unit is usually equipped with input devices such as a touch screen, physical buttons, knobs, and a display screen so that trainees can clearly see the current system status and parameter values. Through this control unit, trainees can simulate the equipment control process in the actual operating environment, including manually switching power supplies, adjusting system response thresholds, etc., so as to gain valuable operating experience in practical training, and safely practice and improve their operating skills without having to touch real equipment. In addition, the equipment operation control unit 4 also allows trainees to perform emergency handling operations in simulated fault scenarios to test and improve their troubleshooting and emergency response capabilities.

[0048] In some embodiments, Figure 3 As shown, the training and assessment module 6 includes an information collection terminal 61 , a camera 62 and a server 63 .

[0049] The information collection terminal 61 is used to obtain the switch setting parameters and compare them with the correct answers to the switch parameters to determine the parameter setting evaluation results of the students.

[0050] Specifically, the information collection terminal 61 is connected to the interface of the device operation control unit 4 to capture the switch setting parameters of the ATSE input by the trainee in real time. The switch setting parameters include but are not limited to key operation settings such as voltage threshold and switching delay. The built-in software of the terminal will automatically compare the parameters set by the trainee with the pre-set correct answers to evaluate their accuracy. Through this comparison, the information collection terminal 61 can determine the correctness of the trainee's parameter settings and give a quantitative evaluation result accordingly, which provides an objective parameter setting evaluation for the practical training assessment.

[0051] The camera 62 is used to obtain the device operation image when the trainee performs device operation control, and send the device operation image to the server 63.

[0052] Specifically, Figure 4 As shown, the camera 62 can be installed in the operating area of ​​the training and assessment equipment, for example, on the top of the equipment, with a larger shooting range, and can monitor the trainee's actual operation of the equipment operation control unit 4 in real time. It captures the trainee's actions and steps when operating the equipment, and transmits these images in real time to the server 63 in the form of a video stream. The high definition and stability of the camera 62 ensure that the captured images can accurately reflect the trainee's operation details, providing reliable visual data for subsequent evaluation.

[0053] The server 63 is used to determine the operation specification evaluation result according to the equipment operation image, and determine the trainee's practical training assessment evaluation result according to the parameter setting evaluation result and the operation specification evaluation result.

[0054] Specifically, the server 63 receives the equipment operation images from the camera 62, and uses the built-in evaluation algorithm to analyze whether the trainees' operation procedures and behaviors comply with the established operation specifications and safety standards. The software in the server 63 can identify and evaluate the trainees' operation sequence, the operation methods used, and the response to emergency situations. Combined with the parameter setting evaluation results provided by the information collection terminal 61, the server 63 comprehensively considers the evaluation of these two aspects and finally determines the evaluation results of the practical training assessment for each trainee. This comprehensive evaluation not only reflects the correctness of the trainees' mastery of theoretical knowledge, but also reflects their standardization and emergency handling capabilities in actual operations, providing comprehensive assessment feedback for coaches and helping to guide trainees to make targeted improvements and improvements.

[0055] In some embodiments, a trained operation specification evaluation model is configured in the server 63, and the server 63 is used to input the equipment operation image into the operation specification evaluation model, and the operation specification evaluation model outputs the operation specification evaluation result.

[0056] Among them, the operation specification evaluation model is a neural network model based on a machine learning algorithm, which can identify and analyze the behavioral patterns of trainees during the equipment operation process. The server 63 uses the equipment operation image captured by the camera 62 as input data and provides it to the evaluation model for in-depth analysis. The operation specification evaluation model identifies the standardization, accuracy and potential safety hazards in the trainees' operations by comparing the trainees' equipment operation images with the pre-stored standard operating procedures and safety specifications. Through this intelligent analysis, the operation specification evaluation model can output a quantitative operation specification evaluation result, which integrates the trainees' performance in terms of operation procedures, techniques, sequence and safety awareness, and provides an objective and accurate operation standardization evaluation for practical training assessment.

[0057] In some embodiments, the operation specification evaluation results include safety gear wearing specification evaluation results, and the operation specification evaluation model is used to identify the positional relationship between the trainee and the safety gear from the equipment operation image, and determine the trainee's safety gear wearing specification evaluation results based on the positional relationship.

[0058] Among them, the evaluation results of the operation specifications include the evaluation results of the safety equipment wearing specifications, such as Figure 5As shown, the operation specification evaluation model uses image recognition technology to analyze the equipment operation image obtained from the camera 62, and accurately identifies the position of the trainees and the safety equipment they use (such as safety helmets, insulating gloves, insulating shoes, etc.). The operation specification evaluation model further evaluates the spatial position relationship between the trainees and the safety equipment, and checks whether the safety equipment is worn and used correctly. Based on these analyses, the operation specification evaluation model can automatically determine the standardization of the trainees in wearing safety equipment, and accordingly give the evaluation results of the safety equipment wearing standards, ensuring that the trainees meet the safety standards in the practical training operations, thereby improving the overall practical training safety and operation standardization.

[0059] In this embodiment, the training process of the operation specification evaluation model involves the use of machine learning and computer vision technology. The model training method can refer to the following steps: First, a large amount of equipment operation image data is collected, which contains images of trainees wearing safety gear correctly and incorrectly. In the image dataset, each sample is marked with a corresponding label indicating whether the safety gear is used and worn correctly.

[0060] Then, the model is trained using supervised learning methods using these labeled image data. Common algorithms include deep learning architectures such as convolutional neural networks (CNN). During the training process, the model learns to recognize the features and patterns of students and safety equipment (such as helmets, insulating gloves, safety belts, etc.) in the image, and understands the spatial relationship between them. Through repeated training and verification, the recognition accuracy of the model continues to improve.

[0061] Finally, when the model is able to identify and evaluate the wearing of safety gear with high accuracy, it can be deployed on the server 63 to analyze the equipment operation images captured by the camera 62 in real time and automatically give the evaluation results of the trainees' safety gear wearing standards.

[0062] In addition, continuous model optimization and retraining are also necessary to adapt to different operating environments and student behaviors to ensure the accuracy and practicality of the evaluation results.

[0063] In some embodiments, the operation standard evaluation result includes an operation action standard evaluation result, and the operation standard evaluation model is used to identify the trainee's operation action from the device operation image and determine the trainee's operation action standard evaluation result based on the operation action.

[0064] The operational specification evaluation results include the operational action specification evaluation results. The operational specification evaluation model uses computer vision and machine learning technology to conduct in-depth analysis of the equipment operation images obtained from the camera 62 to identify the specific actions of the trainees when performing ATSE operations. The operational specification evaluation model can identify and evaluate whether the trainees' actions follow the established operating procedures and safety specifications by learning a large number of standard operation videos. It analyzes the trainees' action sequence, posture, and way of interacting with the equipment to ensure that each step meets safety and operational standards.

[0065] Based on these analyses, the operation standard evaluation model can automatically determine whether the trainees' operations are standardized, and give operation action standard evaluation results accordingly. This helps to ensure that trainees not only understand the theoretical knowledge in practical training, but also can accurately perform practical operations, thereby improving the safety and effectiveness of operations.

[0066] In this embodiment, the training method of the operation specification evaluation model can also refer to the following process: First, a large amount of video image data reflecting correct and incorrect operation actions needs to be collected and annotated. These data are used as training sets, in which each video clip is annotated by professionals to clearly indicate which actions are standard and which are not standard.

[0067] Then, using these annotated video image data, deep learning technology, especially convolutional neural network (CNN), is used to train the model. During the training process, the model learns to recognize and understand the action patterns in the video images, including the type, sequence and execution method of the action. Through repeated training and adjustment, the model gradually improves its recognition accuracy and evaluation reliability.

[0068] In addition, transfer learning techniques can be used to adapt pre-trained models (such as models trained on large-scale video image datasets) to models specific to ATSE operations to improve training efficiency and model performance.

[0069] Ultimately, the fully trained model can automatically analyze new operation video images, identify the trainees' operating actions, and give standardized evaluation results of the operating actions based on preset standards, ensuring that the trainees' operations meet safety and standard requirements.

[0070] In some embodiments, Figure 6 As shown, the server 63 determines the trainee's ATSE operation assessment score based on the wearing specification evaluation results, the operation action specification evaluation results, and the parameter setting evaluation results. The ATSE operation assessment score can be used as the trainee's practical training assessment evaluation result.

[0071] Among them, the evaluation results of wearing specifications, operating action specifications, and parameter setting evaluation results represent the three key evaluation dimensions of wearing specifications, operating actions, and parameter settings, respectively. The server 63 sets full marks for the three key evaluation dimensions of wearing specifications, operating actions, and parameter settings, and gives corresponding scores according to the actual performance of the trainees during the training process. A weight can be assigned to each evaluation dimension, which reflects the relative importance of each dimension in the total score, and then the total score of the trainee is calculated by weighted average.

[0072] This approach ensures transparency and consistency in the scoring process, while allowing weights to be adjusted according to training objectives and safety requirements to achieve a comprehensive assessment of the trainee's operational skills and decision-making ability. Ultimately, the total score provides a quantitative feedback to instructors and trainees, indicating the trainee's overall performance in the ATSE operational assessment and where they need further improvement and improvement.

[0073] In some embodiments, the information collection terminal 61 is also used to obtain the switch displacement information of the dual-way switch simulation unit 5, and determine the parameter setting evaluation result according to the switch displacement information, the switch setting parameters and the correct answer to the switch parameters.

[0074] The information collection terminal 61 can not only capture the switch setting parameters input by the trainee in the equipment operation control unit 4 in real time, but also synchronously obtain the switch position information of the dual-way switch simulation unit 5. The switch position information can represent the switch action state actually performed by the ATSE under the fault condition triggered by the power fault simulation unit 2. The information collection terminal 61 compares and analyzes these real-time position information with the parameters set by the trainee and the preset correct answers, so as to evaluate whether the trainee's parameter settings lead to the correct switch action, ensuring that the automatic switching logic of the ATSE is consistent with the expected operation standard.

[0075] Through this comprehensive evaluation, the information collection terminal 61 can determine the accuracy and effectiveness of the trainees in parameter setting, and provide an objective parameter setting evaluation result for practical training assessment, which helps coaches evaluate trainees' operational skills and decision-making abilities, while guiding trainees to make targeted improvements.

[0076] In some embodiments, the training and assessment module 6 also includes a safety failure simulation unit, which is used to simulate equipment safety failures and issue safety warnings. The equipment operation control unit 4 is also used to receive the trainee's response operation to the safety warning and generate safety response information. The information collection terminal 61 is also used to determine whether the trainee's response operation is qualified based on the safety response information.

[0077] Specifically, the practical training and assessment module 6 of this embodiment can simulate the safety failure scenarios that the equipment may encounter in actual operation, such as condensation, smoke and temperature exceeding the limit, etc., by integrating the safety failure simulation unit, so as to issue corresponding safety warning signals. When facing these simulated safety warnings, trainees need to perform emergency response operations through the equipment operation control unit 4, such as starting the emergency plan, executing troubleshooting steps or adjusting equipment settings. The information collection terminal 61 is responsible for capturing and analyzing the safety response information generated by the trainees in real time, evaluating whether the trainees' response is quick, whether the operation is correct, and whether the measures are appropriate, so as to determine whether the trainees' safety failure handling ability meets the expected standards. This kind of simulation training not only improves the trainees' understanding and handling ability of equipment safety failures, but also strengthens their emergency response and decision-making skills in emergency situations, ensuring the comprehensiveness and practicality of the practical training assessment.

[0078] In some embodiments, the camera 62 is further used to obtain a facial image of the trainee, and the server 63 is further used to identify the identity information of the trainee based on the facial image.

[0079] In this embodiment, the camera 62 in the training and assessment module 6 is used not only to record the trainee's operation process, but also to capture the trainee's facial image. These facial images are then transmitted to the server 63, and the face recognition technology deployed on the server 63 can analyze and process the acquired facial images, and compare them with the trainee's facial information stored in the database, so as to identify and confirm the trainee's identity.

[0080] This function is crucial to ensure the fairness and security of the assessment, and can effectively prevent cheating such as substitution, and ensure the accuracy of the assessment records and the authenticity of the student's identity. Through this automated identity authentication mechanism, Server 63 can establish a safe and reliable assessment file for each student, providing accurate basic data for subsequent performance evaluation and skill analysis.

[0081] In some embodiments, the dual power automatic transfer switch training and assessment equipment also includes a load simulation unit 7, which is used to simulate the power load and provide the load response status of the power load during the switching process of the two power simulation units 1.

[0082] Specifically, the load simulation unit 7 can be used to simulate various load types in the actual power consumption environment, such as lighting, power, special equipment, etc. The load simulation unit 7 can simulate the response of these loads when switching between the two power simulation units 1, including the impact of changes in voltage and frequency on the load, the transient response of the load, and any abnormal behavior that may occur during the power switching process. In this way, trainees can observe and learn the performance of different loads during the power switching process, and understand how to manage and control these loads to ensure the smoothness of the power switching and the stability of the system. The load simulation unit 7 provides trainees with a platform for actual operation and decision-making, allowing them to practice handling various complex power system operation situations in a simulated, risk-controlled environment, thereby improving their proficiency in ATSE operations and their understanding of power system dynamics.

[0083] In some embodiments, the load simulation unit 7 includes a lighting load simulation unit 71, an uninterruptible power supply load simulation unit 72 and a restart load simulation unit 73. The lighting load simulation unit 7 is used to simulate the working condition of the lighting load during the power switching process, the uninterruptible power supply load simulation unit 7 is used to simulate the working condition of the uninterruptible power supply load during the power switching process, and the restart load simulation unit 7 is used to simulate the working condition of the restarted power load during the power switching process.

[0084] Among them, the lighting load simulation unit 71 may include an LED load unit, which can be specifically used to simulate the working conditions of lighting equipment during power switching, such as LED lamps or other lighting devices, to show their response to power changes and whether they can maintain a stable lighting effect.

[0085] The uninterruptible power supply load simulation unit 72 simulates how an uninterruptible power supply system of key equipment such as a UPS (Uninterruptible Power Supply) maintains power supply when power is switched, ensuring that the key equipment is not affected by power interruption.

[0086] The restart load simulation unit 73 is used to simulate the behavior and restart process of devices that need to be restarted to continue working after power interruption, such as some industrial machinery or computer systems, after power is restored.

[0087] Through these detailed simulations, trainees can fully understand and master the specific performance and handling methods of different types of loads in actual power switching operations, thereby improving their understanding of power system operations and their ability to deal with various power faults.

[0088] In some embodiments, the dual power automatic transfer switch training and assessment equipment also includes a display screen 8 for displaying training demonstration content and assessment questions based on the information provided by the training and assessment module 6.

[0089] In this embodiment, the display screen 8, as a key human-computer interaction interface, plays an important role in providing real-time information and guidance to trainees. During the practical training stage, the display screen 8 displays the training demonstration content according to the instructions of the practical training assessment module 6, including ATSE operation videos, animation explanations, theoretical learning materials, etc., to help trainees understand the working principle and operation process of the equipment. Entering the assessment stage, the display screen 8 is used to present specific assessment questions and operating instructions, clearly informing trainees of the assessment requirements and goals, and ensuring that trainees can accurately grasp the assessment tasks. In addition, the display screen 8 can also provide real-time feedback on the trainees' operation results and system status, enhance interactivity and educational effects, and enable trainees to complete training and assessment tasks more attentively and efficiently with visual assistance.

[0090] Specifically, the display screen 8 is connected to the server 63 via a high-speed network interface, and this connection method ensures the efficiency and stability of data transmission. The server 62, as the control center and data processing core of the entire system, is responsible for storing and managing all training and assessment content, including operation demonstration videos, theoretical learning materials, assessment questions, and operation instructions. The display screen 8 displays these contents in real time by receiving the data stream sent by the server 63, providing students with clear operation instructions and real-time feedback.

[0091] The connection between the display screen 8 and the server 63 also supports dynamic updating and remote management, allowing the coach or administrator to remotely update the content on the display screen according to the training needs without directly touching the display screen. This design improves the flexibility and ease of use of the system, making the training and assessment process smoother and more efficient.

[0092] In addition, the display screen 8 can also display personalized training content and assessment results based on the trainee's operation and real-time feedback from the server 63, thereby providing a customized training experience. For example, if the trainee encounters difficulties in a certain operation link, the server can analyze the trainee's operation data and provide additional guidance or suggestions through the display screen to help the trainee overcome the difficulties and improve learning efficiency.

[0093] In short, the connection between the display screen and the server is one of the key technologies for achieving efficient training and accurate assessment in practical training and assessment equipment. It provides students with an intuitive, interactive and personalized learning platform, and also provides coaches with powerful teaching and management tools.

[0094] In some embodiments, the display screen 8 also integrates a voice broadcast function, which enables the display screen 8 to clearly convey the assessment questions, operation prompts and important information to the trainees in the form of voice through the built-in speaker or the connected sound system. This voice broadcast function is particularly suitable for training scenarios that require freeing hands in the operating environment or operating in a noisy environment, ensuring that trainees can accurately receive key instructions and feedback, thereby improving the efficiency of training and the accuracy of assessment. Through the dual information transmission of vision and hearing, this function of the display screen 8 greatly enhances the interactivity and user experience of the practical training assessment equipment.

[0095] In some embodiments, the server 63 may also formulate a targeted learning plan for the trainees based on the trainees' practical training assessment results.

[0096] Specifically, after collecting and analyzing the evaluation results such as the trainees' operation data, wearing specifications, operation action specifications, and parameter settings on the dual power automatic transfer switch practical training and assessment equipment, server 63 uses an integrated data analysis module, machine learning algorithms, and data mining technology to conduct an in-depth analysis of the trainees' performance in the practical training and assessment.

[0097] These algorithms can process a large amount of data from the information collection terminal 61 and the camera 62, including operation accuracy, response time, fault handling efficiency, and compliance with safety regulations. By comparing the trainee's operation data with the preset operation standards and historical performance data, the algorithm can identify the trainee's mastery of specific skills and knowledge points. In addition, the server 63 can also use predictive models to analyze the trainee's learning trends and potential learning obstacles, thereby providing customized suggestions for each trainee's skill improvement and knowledge supplementation.

[0098] Based on these analysis results, Server 63 can generate a comprehensive and detailed skill level and knowledge mastery assessment report, providing a scientific basis for the subsequent formulation of personalized learning plans.

[0099] By analyzing the results of practical training assessment, Server 63 generates a personalized learning plan for each student. The plan includes recommended learning resources, customized simulation training scenarios, necessary theoretical learning courses, and targeted practical exercises, aiming to strengthen the students' weaknesses and further improve their strengths. At the same time, Server 63 will dynamically adjust the learning plan based on the students' performance in subsequent learning and training to ensure that the learning content always meets the students' current learning needs and career development goals, thereby achieving accurate training and efficient learning.

[0100] In this embodiment, the dual power automatic transfer switch training and assessment equipment is used for training to improve the professional skills of trainees by simulating the actual operation environment. The training process is as follows: First, under the guidance of the instructor, the trainees familiarized themselves with the practical training equipment, including two-way simulated power supplies, a power supply fault simulation unit, a power supply monitoring unit, an equipment operation control unit, a dual-way switch simulation unit, and a load simulation unit.

[0101] Afterwards, the trainees received theoretical learning materials and operation demonstrations through the display screen in the practical training and assessment module, and mastered the basic working principles and operation procedures of ATSE.

[0102] After theoretical learning, trainees enter the practical operation stage, where they will personally set the ATSE parameters on the equipment operation control unit, respond to various fault signals triggered by the power fault simulation unit, and observe the real-time data fed back by the power monitoring unit.

[0103] At the same time, students are also required to perform power switching operations through a dual-way switch simulation unit and use a load simulation unit to understand how different loads react during the power switching process.

[0104] During the entire training process, the coach can monitor the trainees' operations in real time through the server and provide feedback and guidance after the training to help trainees consolidate their learning outcomes and make improvements on their deficiencies.

[0105] In this embodiment, the dual power automatic transfer switch training and assessment equipment is used to conduct an assessment to test the trainees' operational skills and theoretical knowledge mastery after the training. The specific assessment process is as follows: Before the assessment begins, the coach sets the assessment parameters and fault simulation scenarios on the server according to the assessment requirements to ensure the fairness and effectiveness of the assessment.

[0106] During the assessment, trainees operate the equipment independently. Faced with the fault signal generated by the power fault simulation unit, they need to quickly and accurately set the ATSE parameters on the equipment operation control unit and perform the correct switching operation.

[0107] At the same time, the trainee's operation process is recorded by the camera and transmitted to the server in real time through the information collection terminal. The operation standard evaluation model in the server analyzes whether the trainee's operation actions are standardized and whether the parameter settings are correct, and calculates the trainee's assessment score based on the evaluation results of the wearing standard.

[0108] After the assessment, the server automatically generates an assessment report containing detailed evaluation results and improvement suggestions. The coach will provide feedback to the trainees based on this information, point out their shortcomings in operation, and provide further learning guidance.

[0109] This process not only assesses the students’ skill level, but also promotes their self-learning and continuous improvement through objective assessment results.

[0110] The dual power automatic transfer switch training and assessment equipment of the embodiment of the present invention is an integrated and intelligent training and assessment system, which is designed to improve the ability of distribution system operation and maintenance personnel in handling dual power automatic transfer switch operation and troubleshooting. By simulating a real dual power supply environment, the equipment provides trainees with a safe and controllable training platform, allowing them to learn and practice ATSE operation skills and emergency handling capabilities without actual operation risks.

[0111] The core components of the equipment include two-way power supply simulation unit 1, power supply fault simulation unit 2, power supply monitoring unit 3, equipment operation control unit 4, dual-way switch simulation unit 5, load simulation unit 7 and training assessment module 6. The two-way power supply simulation unit 1 simulates the main power supply and backup power supply, and can generate preset power supply fault signals such as overvoltage, undervoltage, loss of voltage and phase loss through the power supply fault simulation unit 2 to simulate the actual power supply abnormality. The power supply monitoring unit 3 is responsible for real-time monitoring of the power supply status, capturing changes in key power parameters, and providing data support for the operation of ATSE.

[0112] The equipment operation control unit 4 provides trainees with an intuitive operation interface, enabling them to input and adjust ATSE operation parameters, such as voltage threshold and switching delay, etc. The dual-way switch simulation unit 5 controls the switching between the two power supply simulation units 1 according to the status information provided by the power supply monitoring unit 3 and the parameters set by the trainees, simulating the real ATSE switching action.

[0113] The load simulation unit 7 further enhances the authenticity of the training, and includes the lighting load simulation unit 7, the uninterruptible power supply load simulation unit 7 and the restart load simulation unit 7, which respectively simulate the reactions of different types of power loads during the power switching process. This enables trainees to fully understand and master the characteristics of different loads and their impact on power switching.

[0114] The practical training assessment module 6 is a key part for evaluating trainees' operation skills and decision-making ability. It includes an information collection terminal 61, a camera 62 and a server 63. The information collection terminal 61 is responsible for obtaining the trainees' switch setting parameters and comparing them with the preset correct answers to evaluate whether the trainees' parameter settings are correct. The camera 62 records the trainees' operation process in real time, captures key operation details, and transmits image data to the server 63. The operation standard evaluation model in the server 63 analyzes the trainees' operation actions, evaluates whether their operations are standardized, and combines the parameter setting evaluation results of the information collection terminal 61 to give the final practical training assessment evaluation.

[0115] In addition, the training and assessment module 6 also includes a safety failure simulation unit, which can simulate equipment safety failures and issue safety warnings. Trainees need to respond to these warnings, and the equipment operation control unit 4 records the trainees' safety response operations. The information collection terminal 61 determines whether the trainees' handling is qualified based on these response operations.

[0116] In order to improve the interactivity of training and the efficiency of information transmission, the equipment is also equipped with a display screen 8 with voice broadcast function. The display screen 8 displays operation demonstrations and theoretical guidance content in training mode, and presents examination questions and operation instructions in examination mode. The voice broadcast function ensures that trainees can clearly receive key instructions and feedback, and can accurately understand the examination requirements even in a noisy operating environment.

[0117] In summary, the ATSE training and assessment equipment of the present invention provides an efficient and practical training and assessment platform for power distribution system operation and maintenance personnel by simulating a real dual power supply environment and fault scenario, combined with an intelligent assessment and evaluation system. The equipment not only improves the trainees' operating skills and emergency handling capabilities, but also ensures the overall improvement of the training effect and trainees' capabilities through objective and accurate assessment and evaluation.
