Description

Technical Field

[0001] The present invention relates to the technical field of safety training, and in particular to a method, system, equipment and medium for developing dynamic experience simulation courseware for safety accidents. Background Art

[0002] In today's society, with the rapid development of the economy and the continuous advancement of science and technology, enterprises are facing more and more challenges and opportunities in the process of production and operation. At the same time, the issue of production safety has become increasingly prominent and has become one of the key factors for the sustainable development of enterprises. Safety training is an important means to improve employees' safety awareness and skills. It can help employees understand safety regulations, master safe operating methods, and improve emergency response capabilities, thereby reducing the occurrence of safety accidents. By carrying out safety training, enterprises can improve the safety quality of employees, enhance the safety management level of enterprises, and provide strong guarantees for the safe production of enterprises. This is not only a need for the development of the enterprise itself, but also a requirement for social progress and the protection of employee rights and interests. However, traditional safety training methods often have many limitations; On the one hand, traditional safety training mostly adopts the form of classroom lectures and video watching, which are relatively simple and lack interactivity and immersion. When receiving training, employees often only passively receive knowledge and find it difficult to truly understand the dangers and consequences of safety accidents. For example, in classroom lectures, employees may only hear some safety regulations and theoretical knowledge, but lack intuitive feelings about the application of this knowledge in actual work. Although watching videos can show some scenes of safety accidents, they are only flat presentations and cannot allow employees to experience the tension and danger when an accident occurs in person; On the other hand, the types of safety risks in different industries vary, and traditional safety training methods are difficult to accurately train for risks in specific industries. For example, the manufacturing industry may face risks such as mechanical injuries and chemical leaks; the construction industry may face risks such as falling from heights and being hit by objects. Traditional safety training often cannot fully cover the special risks of various industries, resulting in less than ideal training results; In addition, employees have different levels of awareness of safety accidents, and traditional safety training methods are difficult to meet the personalized needs of different employees. Some employees may have a certain understanding of safety accidents, but lack in-depth understanding and response capabilities; while some employees may have a weak understanding of safety accidents and need more systematic and comprehensive training; Therefore, a method, system, equipment and medium for developing dynamic experience simulation courseware for safety accidents are proposed.

It should be noted that if there are substantially the same results, the method of the present application is not limited to the method of the present invention. Figure 1 The process sequence shown is limited. Figure 1-Figure 2 As shown: A method for developing a dynamic experience simulation courseware for a safety accident, comprising the following steps: Step 1: Obtain the demand data for production safety training, analyze the demand data based on data analysis tools, and obtain the demand analysis results; specifically: First, through questionnaire surveys, field visits, expert interviews and other methods, we collected extensive data on the demand for production safety training, including safety risk points in different industries, the knowledge level and skill requirements of the trainees, and past safety accident cases. Then, use professional data analysis tools to conduct in-depth analysis of the collected demand data, extract key information, clarify the key areas and specific needs of training, and form a detailed demand analysis results report.

[0020] Step 2: Based on 3D modeling software and virtual reality engine, build a safety accident experience simulation scenario model according to the demand analysis results. Specifically: First, we use advanced 3D modeling software to build a high-precision model based on the actual safety accident scene and equipment characteristics, including the environment of the accident site, related equipment and facilities, personnel, etc. Then, using a powerful virtual reality engine, the constructed 3D model is integrated into the virtual environment, adding real physical effects, light and shadow effects, and sound effects to create a highly realistic safety accident experience simulation scene.

[0021] Step 3: Design a variety of dynamic safety accident experience projects and multiple interactive methods in the safety accident experience simulation scene model. Specifically: First, we design a variety of dynamic experience projects based on different types of safety accidents, such as simulating vibration, impact, smoke, flame and other effects when an accident occurs, so that users can experience the danger of the accident in person; Then, design a variety of natural and convenient interaction methods, such as gesture control, voice interaction, touch operation, etc., so that users can easily interact with the simulation scenes and explore different safety accident scenarios and response methods.

[0022] Step 4: Based on the results of the demand analysis, combined with safety regulations and standards, design the course content of the safety accident dynamic experience simulation courseware, and present the course content in multimedia form. Specifically: First, based on the results of demand analysis and combined with safety regulations and standards, a comprehensive and systematic safety accident dynamic experience simulation courseware course content is designed, including safety knowledge explanation, accident case analysis, emergency response process, etc. Then, use multimedia to present the course content, such as text, pictures, videos, animations, etc., to enhance the attractiveness and readability of the course and improve the user's learning effect.

[0023] Step 5: Based on virtual reality software development tools, develop software for dynamic experience simulation courseware of safety accidents. Specifically: First, select appropriate virtual reality software development tools, such as Unity3D, Unreal Engine, etc., and combine virtual reality technology to develop dynamic experience simulation courseware for safety accidents; Then, the software is optimized and debugged to ensure the stability, fluency and performance of the courseware, while achieving compatibility with different hardware devices.

[0024] Step 6: Develop a test plan and standards, conduct a comprehensive test on the developed safety accident dynamic experience simulation courseware, and obtain the test results. Specifically: First, formulate detailed testing plans and standards, including functional testing, performance testing, user experience testing and other aspects, and conduct comprehensive testing on the developed safety accident dynamic experience simulation courseware; Then, invite different types of users to conduct trials and evaluations, collect users' feedback and suggestions, and objectively evaluate the effectiveness of the courseware.

[0025] Step 7: Based on the test results, discover and solve the problems in the courseware, and optimize and improve the courseware. Specifically: First, based on the test results and user feedback, timely discover the problems and deficiencies in the courseware; Then, we conduct in-depth analysis on the problems, develop effective optimization and improvement plans, iteratively upgrade the courseware, and continuously improve the quality of the courseware and user experience.

[0026] In this embodiment, specifically: in step one, the demand data for production safety training includes the types of safety risks in different industries, the level of awareness of employees about safety accidents, and the specific requirements of the enterprise for safety training. Among them, the types of safety risks in different industries are collected and sorted out by referring to industry reports, safety regulations and historical accident records to find out the types of safety risks unique to each industry. For example, the manufacturing industry may face risks such as mechanical injuries and chemical leakage; the construction industry may face risks such as falling from heights and being hit by objects; the level of awareness of employees about safety accidents is assessed through questionnaires, online tests, etc., to assess the employees' understanding of current safety regulations, their ability to identify potential risks, and the lessons learned from past safety accidents. These data are used to understand the current cognitive status of employees, thereby determining the focus and depth of training; the specific requirements of the enterprise for safety training are obtained through in-depth communication with the enterprise management and relevant departments to understand the specific expectations, goals and desired effects of safety training after training. These requirements may include the targeted training content, the diversity of training forms and the measurability of training effects.

[0027] Data analysis tools include statistical analysis software and data mining tools. Statistical analysis software (such as SPSS) is used to conduct quantitative analysis of data, identify key safety risk points and training needs, and extract key information such as the main safety risk points in various industries, the distribution of employees' cognitive levels, and the specific concerns of enterprises on training through descriptive statistics, correlation analysis and other methods. Data mining tools (such as Python's Pandas and Scikit-learn) are used to deeply explore the patterns and trends behind the data. Through cluster analysis, association rule mining and other methods, potential safety risk points, weak links in employees' cognitive levels, and commonalities and differences in training needs are discovered.

[0028] In this embodiment, specifically: in step 2, building a safety accident experience simulation scene includes environmental modeling, building modeling, equipment and facility modeling, and character modeling. Among them, environmental modeling is based on the actual working environment of the target industry, such as factory workshops, construction sites, mines, etc., and is carefully modeled, including the restoration of topography, simulation of weather conditions (such as rain, snow, fog, etc.) and the presentation of time changes (such as day and night). Through environmental modeling, we create a realistic virtual working environment for students; architectural modeling is based on the size, structure and appearance characteristics of the real building, and is accurate in three-dimensional modeling, including the appearance material, internal layout of the building, etc. , door and window locations and other details. Through building modeling, students can freely shuttle between rooms and floors in a virtual environment to observe and understand the potential safety hazards inside the building. Equipment and facility modeling accurately models various types of production equipment, safety facilities, emergency equipment, etc. according to the actual needs of the target industry, including the appearance, function, operation method and possible failure mode of the equipment. Through equipment and facility modeling, students can become familiar with the operation process and safety specifications of the equipment in a virtual environment, and understand the safety accidents that may be caused by equipment failure. Character modeling includes creating characters of different occupations, genders, and age groups, and designing corresponding actions and expressions for them. Through character modeling, students can interact with other characters in a virtual environment to jointly cope with the challenges of safety accidents.

[0029] The virtual reality engine has physical simulation and light and shadow effects functions. Among them, the physical simulation function can simulate real physical phenomena and interactive effects. For example, when students operate equipment in a virtual environment, the engine will calculate the movement trajectory and collision effect of the equipment in real time according to the physical characteristics and operation methods of the equipment. This physical simulation function makes the students' experience in the virtual environment more real and immersive; the light and shadow effects function includes the simulation of natural lighting, the generation of shadow effects, the presentation of lighting changes, and the addition of special effects (such as flames, smoke, etc.). Through the light and shadow effects function, a more realistic and shocking virtual safety accident experience scene can be created for students.

[0030] In this embodiment, specifically: in step three, the dynamic experience project of safety accidents includes simulating the vibration intensity, impact, high fall, shaking, tilt and temperature change when the accident occurs. Among them, the vibration intensity and impact simulation uses a vibration platform and a mechanical feedback device to simulate the vibration intensity and impact generated when different safety accidents occur. For example, when simulating an earthquake scene, the vibration platform will generate corresponding vibrations according to the intensity and direction of the earthquake, so that the trainees can feel the strong ground vibration. When simulating a vehicle collision or explosion scene, the mechanical feedback device can simulate a strong impact, making the trainees feel as if they are at the scene of the accident; the high fall and shaking simulation uses a virtual reality headset combined with a dynamic seat. In this way, when a trainee falls while working at high altitude in a virtual environment, the dynamic seat will quickly adjust its posture to simulate the feeling of weightlessness and falling; when simulating a ship or airplane shaking due to bad weather, the dynamic seat will make corresponding adjustments according to the shaking amplitude of the virtual environment, allowing the trainees to feel the real shaking experience; the tilt and temperature change simulation is achieved through the tilting platform and temperature control system. For example, when simulating the tilt of the ground caused by the collapse of a building or a landslide, the tilting platform will make corresponding adjustments according to the tilt angle of the virtual environment; when simulating a fire or an extremely cold environment, the temperature control system will adjust the indoor temperature to allow the trainees to feel the real temperature changes.

[0031] The interaction methods include gesture recognition, voice interaction and somatosensory interaction. Through the gesture recognition function, students can interact with the virtual environment through gesture operations; through the voice interaction function, students can interact with the virtual environment through voice commands, such as asking for safety tips, requesting help or confirming operations, etc.; through somatosensory interaction devices (such as somatosensory controllers, full-body motion capture systems, etc.), students' body movements and posture changes can be captured and mapped to the virtual environment in real time.

[0032] In this embodiment, specifically: in step 4, the course content includes animation demonstration of key provisions of safety regulations, video analysis of real accident cases, and illustrated explanation of safety standards and safety accident handling process tips. Through carefully produced animation videos, complex legal provisions are transformed into easy-to-understand images and scenes, so that students can master the core content of safety regulations in a relaxed and pleasant atmosphere. These animation videos not only cover the basic principles, scope of application and specific provisions of safety regulations, but also deepen students' understanding and memory through vivid cases and examples; through real accident case video analysis, not only the whole process and serious consequences of the accident are demonstrated, but also the causes of the accident, accountability and preventive measures are deeply analyzed. By watching these videos and analyzing the deep-seated reasons behind them, trainees can deeply understand the seriousness and harmfulness of safety accidents, and thus more consciously abide by safety regulations and implement safety standards; through clear charts, pictures and concise and clear text descriptions, the specific requirements, implementation methods and precautions of various safety standards are introduced in detail. At the same time, detailed safety accident handling process tips are also provided for trainees, including accident reporting, on-site disposal, personnel evacuation, emergency rescue and other links. The specific steps and precautions of these tips can not only help trainees quickly take correct response measures when a safety accident occurs, but also improve their emergency response capabilities and self-protection capabilities.

[0033] In this embodiment, specifically: in step 5, the software development method of the safety accident dynamic experience simulation courseware includes the following steps: Step 1: Import the constructed safety accident experience simulation scene model into the virtual reality software development tool, and make preliminary layout and adjustments to the imported scene so that it presents a reasonable proportion and position relationship in the virtual reality environment; Step 2: Based on the physical simulation function of the virtual reality engine, add real physical properties to the objects in the scene, such as gravity, collision detection, etc., to enhance the authenticity of the dynamic experience, and configure light and shadow effects, adjust the light intensity, color, shadow effect, etc. according to the actual situation, to create a realistic visual effect; Step 3: Develop vibration intensity simulation, impact simulation, high-fall simulation, shaking simulation, tilt simulation and temperature change simulation; Among them, the vibration and impact simulation controls the vibration platform and mechanical feedback device through virtual reality equipment and software interface, and outputs the corresponding vibration and impact effects according to the type and intensity of the simulated safety accident; High-fall, sway and tilt simulation: By combining dynamic seats or VR headsets with equipment, high-fall, sway and tilt simulation functions are developed. The movement trajectory and speed of these devices are controlled by software, allowing students to feel real physical changes in a virtual environment. Temperature change simulation, presenting temperature changes in a virtual environment through temperature control system or software simulation.

[0034] Step 4: Create and integrate gesture recognition, voice interaction, and somatosensory interaction; Among them, gesture recognition enables students to interact with the virtual environment through gesture operations, which usually requires the development of professional gesture recognition equipment or software SDK; Voice interaction enables students to interact with the virtual environment through voice. By writing voice command recognition algorithms and response logic, students can control the virtual environment or obtain information through voice. Somatosensory interaction uses somatosensory devices (such as somatosensory controllers, full-body motion capture systems, etc.) to integrate somatosensory interaction functions. By capturing the trainees' body movements and posture changes and mapping them into the virtual environment, a more natural and intuitive interactive experience is achieved.

[0035] Step 5: Create and integrate animations to demonstrate safety regulations, case videos, and graphic explanations of safety standards and accident handling tips. Use animations to present legal provisions and regulations, making it easier for students to understand and remember them. Use case analysis and graphic explanations to deepen students' understanding of safety knowledge and emergency handling capabilities. Step 6: Optimize software performance, perform compatibility testing, and perform error repair and debugging; Among them, performance optimization includes graphics rendering efficiency, memory management, CPU occupancy rate and other aspects to ensure smooth operation of the software on different hardware configurations and operating systems; Compatibility testing includes compatibility testing with different resolutions, different screen sizes, and different operating systems to ensure that the courseware can run stably and present consistent results; Error repair and debugging solve various problems that occur during software operation (such as crashes, freezes, functional failures, etc.) and optimize the user experience. At the same time, the repair process and debugging results are recorded for subsequent maintenance and upgrades.

[0036] In this embodiment, specifically: in step six, the test plan includes functional testing, performance testing, compatibility testing and user experience testing; the test standards are formulated based on relevant industry specifications and user needs.

[0037] Embodiment 2: Based on the first embodiment, a method for developing a dynamic experience simulation courseware for a safety accident also includes the following steps: Step S100: Obtain an artificial intelligence voice assistant and conduct a customized development platform so that it can understand different specific terms and questions in the field of safety training; Step S200: Integrate the intelligent voice assistant into the safety accident dynamic experience simulation courseware according to specific terms and questions in the field of safety training, and determine to interact with the courseware through voice; Step S300: Analyze the user's learning data based on a machine learning algorithm and establish a personalized learning model; Step S400: According to the user's learning progress and performance, the learning model automatically adjusts the course content and difficulty to provide the user with personalized learning suggestions; Step S500: Based on the personalized learning model, optimize the light and shadow effects of the virtual scene, add special light and shadow effects, build a physical simulation algorithm based on real-time light and shadow tracking technology, and integrate the physical simulation algorithm and light and shadow special effects technology into the safety accident dynamic experience simulation courseware for testing and optimization; Step S600: Based on user feedback and test results, improve the physical simulation algorithm and light and shadow special effects technology to enhance the authenticity of object movement and collision in safety accidents.

[0038] Specifically, the present invention improves the personalized learning experience through artificial intelligence technology. The intelligent voice assistant can understand specific terms and questions in the field of safety training and provide users with accurate answers and guidance. This allows users to get help at any time when they encounter problems during the learning process, thereby improving learning efficiency.

[0039] The personalized learning model automatically adjusts the course content and difficulty according to the user's learning progress and performance, providing users with tailored learning plans. Each user can learn at their own pace and ability to better meet their personalized needs.

[0040] Enhanced interactivity and participation, voice interaction is more natural and convenient, users can interact with courseware through voice without manual operation. This interactive method increases the fun and participation of learning and makes the learning process more vivid.

[0041] Personalized learning models can provide users with timely feedback and suggestions, encourage users to actively participate in learning, and improve their learning motivation.

[0042] Improve learning outcomes and knowledge mastery Personalized learning suggestions help users learn weak links in a targeted manner and strengthen their grasp of key knowledge. With the guidance of the intelligent tutor system, users can learn more efficiently and improve their learning results.

[0043] Intelligent voice assistants and personalized learning models can provide users with opportunities to review and consolidate at any time, deepening their memory and understanding of knowledge.

[0044] The present invention improves the sense of reality and immersion through physical simulation algorithms and light and shadow special effects technology. The advanced physical simulation algorithm makes the movement and collision of objects in safety accidents more realistic, making users feel as if they are at the actual accident scene. This sense of reality can enhance users' sense of tension and crisis, and improve their understanding and attention to safety accidents.

[0045] Real-time light and shadow tracking technology and special light and shadow effects add realistic light and shadow effects to the virtual scene, further enhancing the user's sense of immersion. Users can learn in a more realistic environment and better understand the process and consequences of safety accidents.

[0046] Enriching experience projects and teaching content, new physical simulation algorithms and light and shadow special effects technology can be applied to more types of safety accident dynamic experience projects, increasing the diversity and complexity of experience projects. For example, more complex accident scenes such as explosions and fires can be simulated to allow users to experience different degrees of danger and challenges.

[0047] Rich light and shadow effects can be used to display teaching content such as safety regulations, standards and accident handling processes, making the teaching content more vivid, easy to understand and remember.

[0048] Improving the quality and competitiveness of courseware and introducing new technologies can make safety accident dynamic experience simulation courseware more competitive in the market. Compared with traditional safety training methods, courseware with advanced physical simulation and light and shadow effects can attract more users and improve user satisfaction.

[0049] Continuously improving and optimizing physical simulation algorithms and light and shadow effects technology can enhance the quality and stability of courseware and provide users with a better learning experience.
