[0002] In the field of electronic engineering and related technologies, the oscilloscope is an indispensable measurement tool that can intuitively display the waveform of electrical signals, helping engineers and technicians perform signal analysis, fault diagnosis, and performance testing. Traditional oscilloscope training usually relies on physical equipment, and learners need to directly operate the oscilloscope in a laboratory or workplace to learn how to use it. However, this training method has some obvious limitations: (1) Physical oscilloscope equipment is expensive, especially high-performance oscilloscopes, which have high purchase costs and require regular maintenance and updates, increasing the cost of learning; (2) Direct operation of physical oscilloscopes may pose safety risks, especially for beginners, as improper operation may cause equipment damage or personal injury; (3) Learning efficiency: Physical oscilloscope training often requires waiting for the device to be idle, and the operation process may be slow, which limits learning efficiency and training continuity.

[0003] With the rapid development of virtual reality (VR) technology, virtual simulation training has become possible. VR technology can create an immersive virtual environment in which users can interactively operate and learn. However, although VR technology has been widely used in games, education, and training, VR training systems for oscilloscope operation have not yet been popularized. Most of the existing VR training systems are concentrated in high-risk or high-cost fields such as flight simulation and surgical training, while for professional tools such as oscilloscopes, the development of VR training systems is relatively lagging.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. The "first", "second" and similar words used in the embodiments of the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. "Including" or "comprising" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0041] First, some technical terms used in the present invention are explained:

[0042] Virtual Reality (VR), as the name implies, is the combination of virtuality and reality (using specific technology to generate a virtual situation, but people feel it is real). Theoretically speaking, virtual reality (VR) is a computer simulation system that can create and experience a virtual world. It uses computers to generate a simulated environment and immerse users in it. Virtual reality uses real-life data, electronic signals generated by computer technology, and combines them with various output devices to transform them into phenomena that people can feel. These phenomena can be real objects in reality, or substances that are invisible to our naked eyes, expressed through three-dimensional models. Because these phenomena are not what we can see directly, but the real world simulated by computer technology, it is called virtual reality.

[0043] An oscilloscope is an electronic measuring instrument with a wide range of uses. It can transform invisible electrical signals into visible images, making it easier for people to study the changing processes of various electrical phenomena. The oscilloscope uses a narrow electron beam composed of high-speed electrons to hit a screen coated with fluorescent material to produce tiny spots of light (this is the working principle of a traditional analog oscilloscope). Under the action of the measured signal, the electron beam is like the tip of a pen, which can draw a curve of the instantaneous value of the measured signal on the screen. The oscilloscope can be used to observe the waveform curves of various signal amplitudes changing over time, and it can also be used to test various electrical quantities, such as voltage, current, frequency, phase difference, amplitude modulation, etc.

[0044] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] Embodiment 1

[0046] The embodiment of the present invention provides a VR-based oscilloscope use training system, such as Figure 1 As shown, it includes: training task scenario library, VR interaction module, data processing module and analysis module.

[0047] The training task scenario library is used to store different oscilloscope 3D models and 3D models of the device under test, as well as task scenarios for performing different training operations using the oscilloscope.

[0048] The training task scenario library includes: a model building unit, a storage query unit and a scene generation unit; the model building unit is used to build oscilloscope 3D models of different models and specifications, as well as different 3D models of devices under test; the storage query unit is used to store oscilloscope 3D models and 3D models of devices under test, and query the corresponding oscilloscope 3D models and 3D models of devices under test according to the specified training tasks; the scene generation unit is used to generate the linkage characteristics of the queried oscilloscope 3D model and the 3D model of the device under test, and generate task scenarios according to the training tasks.

[0049] In this embodiment, the model unit constructs 3D models of oscilloscopes of different models and specifications by acquiring drawings from oscilloscope manufacturers, and separately models the operable parts of the model, and then models the equipment that needs to be measured in real projects to obtain different 3D models of the equipment to be tested; the unit can also regularly add new oscilloscope models and specifications based on user feedback and market research to expand the coverage of the training task scenario library, and also supports the import of custom models, allowing users to upload specific oscilloscopes or equipment to be tested models according to their needs, thereby increasing the personalization and practicality of training. The storage query unit is used to store the constructed oscilloscope 3D model and the equipment to be tested 3D model, and query and extract the corresponding oscilloscope 3D model and the equipment to be tested 3D model according to the specified training tasks; the unit can also use an intelligent recommendation algorithm to recommend the most suitable training tasks and models based on the trainees' training history and operating habits, so that the trainees can practice after completing the specified training. The scenario generation unit generates the linkage characteristics between the models based on the extracted oscilloscope 3D model and the 3D model of the device under test according to the actual oscilloscope principles. At the same time, it simulates the complex electronic testing environment according to the actual working scenario, including different signal interference, equipment failure and other scenarios. Finally, it generates the task scenario according to the training task.

[0050] The VR interaction module is used to show the trainees the oscilloscope 3D model and task scenarios, collect the trainees' operation action information, and send the operation action information to the data processing module.

[0051] The VR interaction module includes: a scene display unit, an action acquisition unit and an information transmission unit; the scene display unit is used to display the operational task scene to the trainees. In this embodiment, VR glasses are used to display the task scene; the action acquisition unit is used to collect the operation action information of the trainees during training. In this embodiment, the action acquisition unit uses motion capture gloves, which can accurately capture the operation action information of the trainees; the information transmission unit is used to send the operation action to the data processing module and the analysis module. In this embodiment, the operation action information includes but is not limited to the trainees' gestures, positions, operation sequences, etc.

[0052] The data processing module updates the oscilloscope 3D model and task scene based on the operation action information.

[0053] The data processing module includes: a first information receiving unit, a model updating unit and a scene updating unit; the first information receiving unit is used to receive operation action information; the model updating unit is used to denoise the operation action information and update the status of the oscilloscope 3D model and the 3D model of the device under test based on the processed action information; the scene updating unit updates the task scene in real time according to the updated model.

[0054] In this embodiment, the model update unit first performs denoising on the operation action information, and uses digital filtering technology (such as Kalman filter, median filter, etc.) to denoise the collected operation action information to reduce the impact of noise and environmental interference on the data. At the same time, the denoised data is normalized to ensure that the data from different sensors are synchronized in time, so as to correctly associate the trainee's actions with the changes in the model state; then, the trainee's operation action information is parsed into specific operation commands, such as rotating knobs, switching buttons, etc. The operation commands are mapped to the specific parameters of the oscilloscope 3D model and the 3D model of the device under test, such as adjusting the frequency, changing the input signal, etc. According to the parsed operation commands, the state parameters of the oscilloscope 3D model and the 3D model of the device under test are updated in real time, such as adjusting the knob position, changing the signal strength, etc.; for actions that may cause damage to the equipment or do not comply with the operating procedures, the system will limit execution and provide corresponding error prompts; when the operation causes the model state to be abnormal, a mechanism for restoring to the most recent correct state is provided to ensure the continuity of training. After updating the model state, the validity of the operation is verified by analog signal feedback to ensure that the change in the model state is consistent with the trainee's operation intention. Figure 1The scene update unit uses 3D rendering technology to render the scene in real time according to the latest status of the model, ensuring that the scene seen by the trainees is synchronized with the operation actions. After that, it continues to process the logical relationship in the scene, such as the connection status and signal transmission between the oscilloscope and the device under test, to ensure the accuracy and coherence of the scene.

[0055] The analysis module evaluates the training effect based on the operation action information.

[0056] The analysis module includes: a second information receiving unit, a performance analysis unit and a feedback unit; the second information receiving unit is used to receive operation action information; the performance analysis unit analyzes the accuracy of the trainee's operation based on the operation action information and evaluates the training effect of the trainee; the feedback unit generates improvement suggestions for the trainee based on the evaluation results.

[0057] In this embodiment, the operational action information of the performance analysis unit is a sequence of operational steps. The amplitude of each adjustment of the knob is converted into an adjustment accuracy feature, and the difference between the measured frequency value and the actual value is converted into a measurement error feature. In order to eliminate the influence of different feature dimensions, it is necessary to standardize the features and scale all feature values ​​to between 0 and 1. After that, a support vector machine is used to construct an oscilloscope function mastery evaluation model, and the historical operational action information and historical evaluation results are used as training data sets to train the evaluation model to obtain a final evaluation model. Then, the collected operational action information is input into the final evaluation model to obtain an evaluation result of the training effect.

[0058] The technical solution of the present invention provides a low-cost, high-security, and highly accessible training platform by simulating a real oscilloscope operating environment. It not only greatly reduces the cost and maintenance costs of physical equipment, but also ensures that users can perform operation training in an environment without electrical safety risks. The flexibility of the system and the real-time feedback mechanism allow users to train according to their own schedule and learning progress, and obtain operational feedback and improvement suggestions in a timely manner. In addition, personalized learning, collaborative learning modules, and environmental simulation functions make training more efficient and practical, and enhance the learning experience. The system can also be updated according to the latest oscilloscope models and technologies to ensure that users have the latest operating skills. In summary, this system is an efficient, safe, and economical oscilloscope operation training solution that is suitable for a wide range of education and training scenarios.
