Description

Technical Field

[0001] The invention relates to an interactive training system capable of dynamic configuration and an application method, belonging to the field of production safety training. Background Art

[0002] Currently, the most widely used VR training systems mainly provide targeted training in a specific field. They usually adopt the form of stand-alone software and the training content and process are relatively fixed. Trainees participating in the training are prone to path dependence, and training new content requires the redevelopment of a corresponding software system, which will lead to repetitive function development.

[0003] Existing VR training systems are typically hard-coded, with the 3D content and training control flow already defined at launch. Implementation typically involves creating the virtual 3D scene using 3dsMax, and then using game engines (such as Unity and Unreal) to drive the scene's interactions.

[0004] The existing technical solutions have the following problems:

[0005] The training content is fixed, which makes trainees prone to path dependence and reduces the training effect;

[0006] Instructors are unable to obtain and analyze the training content and assessment results of each trainee;

[0007] It is impossible to conduct combined targeted training and assessment on specific training content;

[0008] Every update of the virtual training scenario requires the re-release and update of the software system;

[0009] Unable to dynamically expand and switch training content and virtual scenarios;

[0010] It is impossible to effectively intervene in the training process to improve the training effect. Summary of the Invention

[0021] User role and authority management module: supports administrators to configure user roles and authorities;

[0022] Virtual scene reconstruction module: This module determines the virtual scene to be represented by the current system based on the user's job type and the list of hidden dangers to be trained. It uses the resource information table in the database unit to obtain the scene model ID, normal equipment model ID, hidden danger equipment model ID, and worker model ID in the virtual scene to be represented. It then configures the resource IDs on the web side, binds the aforementioned model resources to the control logic required for overall virtual scene teaching, learning, training, or assessment, generates a JSON file, and completes the dynamic configuration of the scene.

[0023] Information explanation module: After the virtual scene is built, the hidden dangers in the scene are explained. The explanation includes the basis for determining the hidden dangers, the classification of the hidden dangers, and the hidden danger rectification measures;

[0024] Collaborative teaching module: can simultaneously control the display content of each client and explain the selected hidden danger knowledge points;

[0026] Preferably, the student training module completes the construction of the virtual scene according to the scene dynamic configuration information in the following manner:

[0027] The student training module reads the resource information in the JSON file and determines whether the required model resources exist locally;

[0028] If so, load the corresponding model resource; otherwise, obtain the server location of the model library unit, download the model resource on the server, save it locally, and load the resource at the same time;

[0031] Preferably, the collaborative teaching module needs to build a network collaborative environment, and the client unit guidance module and the client use network synchronization to interact, all ports are connected to the same network server, and the server is responsible for data distribution between the ports.

[0032] Preferably, the collaborative teaching module uses RPC remote calls to synchronize model states between different clients.

[0033] Preferably, the system administrator module and the client unit guidance module are both configured and service released on the Web side.

[0034] An application method of a dynamically configurable interactive training system, comprising:

[0035] The administrator on the server side assigns roles and configures permissions for the client units that currently want to conduct interactive training;

[0036] The administrator of the client unit configures the list of hidden dangers to be trained for different types of work in the client unit on the client unit;

[0037] After the client's user logs into the system, the system determines the virtual scene to be displayed by the current system based on the user's job type and the list of hidden dangers to be trained. It uses the database unit and model library unit to obtain the 3D model resource link, binds the control logic, extracts the corresponding 3D model, and dynamically loads it into the training scene to complete the construction of the virtual scene.

[0038] If the user selects the teaching mode, the user's perspective will be locked to the customer unit administrator's perspective. From the customer unit administrator's perspective, the system will explain the hidden dangers in the current virtual scene one by one, and teach the methods of troubleshooting and rectifying the hidden dangers.

[0039] If the user selects the learning mode, the user can click on the hidden danger on the interface to learn the content of the hidden danger and the rectification method; the hidden danger content includes the basis for determining the hidden danger and the classification of the hidden danger;

[0040] If the user selects the training mode, the user will roam autonomously in the virtual scene, find potential hazards in the virtual scene and make corrections. The system will display the current training progress in real time. During the training, the user can select the "Help" function to prompt the potential hazards that have not yet been discovered in the current virtual scene, and correct them one by one to complete the training.

[0041] If the user selects the assessment mode, the user will roam autonomously in the virtual scene, find potential hazards in the scene and make corrections within a limited time. After the assessment is completed, the system will record the assessment data and generate the assessment results.

[0042] Preferably, the virtual scene construction process is as follows:

[0043] Determine the virtual scene to be displayed by the current system based on the user's job type and the list of hidden dangers to be trained. Use the resource information table in the database unit to obtain the scene model ID, normal equipment model ID, hidden danger equipment model ID, and worker model ID in the virtual scene to be displayed. Configure the resource ID on the web side, bind the above-mentioned various model resources with the control logic required for the overall virtual scene teaching, learning, training, or assessment, and generate a JSON file.

[0044] Model resources are extracted based on the resource information in the JSON file and dynamically loaded into the scene. After loading is completed, the positions and angles of normal equipment and equipment with hidden dangers are configured according to the production status of the workshop, and the corresponding equipment is dynamically instantiated to the specified position to complete the three-dimensional construction of the virtual scene.

[0045] Preferably, the model resource is extracted according to the JSON file resource information and dynamically loaded into the scene as follows:

[0046] Determine whether the required model resources exist locally based on the JSON file resource information;

[0047] If so, load the corresponding model resource; otherwise, obtain the server location of the model library unit, download the model resource on the server, save it locally, and load the resource at the same time;

[0048] Repeat the above steps to traverse all resource information in the JSON file and complete the dynamic loading of model resources into the scene.

[0049] The beneficial effects of the present invention compared with the prior art are:

[0050] (1) The present invention is based on dynamic loading technology to achieve the diversity of training scenarios and the scalability of training logic, thereby improving the adaptability of the system in different training scenarios. Virtual training scenarios can be published and updated as needed, and training content and virtual scenarios can be dynamically expanded and switched at any time according to demand. The training content is not fixed, and combined targeted training and assessment can be carried out for specific training content. Compared with the traditional single training path and solidified training content, the present invention can effectively intervene in the training process, greatly improve the training effect, and reduce costs at the same time, achieving the purpose of a set of systems to achieve multiple safety hazard training.

[0051] (2) The present invention supports the administrator of the client unit to select the training or assessment content and display the assessment results.

[0057] The present invention will be further described below with reference to the accompanying drawings.

[0058] The system of the present invention uses the database as the intermediate node, adopts the combination of B / S and C / S, and fully utilizes the management convenience of Web services and the performance advantages of local operation. Administrators can remotely manage system resources through web services, and users can access system functions through local terminals. The overall framework of the system is as follows Figure 1 Each client obtains the current training scene resource list by accessing the database unit and the model library unit, and downloads and loads the corresponding 3D resources from the server to dynamically compose the training scene.

[0059] like Figure 1 As shown in the figure, the overall hierarchical structure of the system is divided into "basic support unit", "database unit, model library unit", "simulation training support unit" and "application platform". In addition, in order to ensure the security and reliability of the system operation and the subsequent scalability of the system, the system system also includes standards and normative documents such as "usage specifications" and "security assurance" mechanisms.

[0060] Basic support unit: It supports and guarantees the safe and reliable operation of the system, and provides the necessary software and hardware support environment for the operation of the interactive training system. The hardware environment consists of two parts. One part is the hardware environment running on the management side, including computer room infrastructure, hardware and network, security and disaster recovery, etc.; the other part is the hardware environment running in each customer unit, mainly including servers, routers, switches, etc. Among them, the computer room infrastructure includes the power distribution system, air conditioning and fresh air system, fire alarm system, weak current control system, cabinet system and lightning protection system required for the construction of the data center computer room. Hardware and network include servers, networks, storage, backup equipment, etc. Security and disaster recovery include storage backup equipment, security and confidentiality systems, and off-site disaster recovery solutions. The software environment running on the management side and running in each customer unit includes operating system, database, and VR operating environment.

[0061] The database unit and model library unit are the foundation of this system. The database unit stores various types of information in the form of fields, including a user information table, a resource information table, and an operating procedure table. The user information table is used to store all users' basic information (name, unit, phone number), permissions, and job titles. The resource information table is used to store information on various scenarios involved in safe production, information on the various devices involved in each scenario, information on potential hazards involved in each scenario, and information on the training results of trainees. The operating procedure table is used to store the operating procedures for each user group, including administrators and various job titles of client units.

[0062] Database units usually use tablespaces, data tables, fields, attributes, etc. to store and manage related data. The database in the system mainly consists of data tables and their dependencies, views, and other auxiliary functions.

[0063] The model library unit includes various scenario models involved in safe production, models of normal equipment, models of equipment with potential hazards, and worker models. These models are typically stored in the form of files, including white models, textures, maps, animations, audio, video, and 3D landscape data. Scenario models correspond one-to-one with scene information in the resource information table via field IDs. Normal equipment models correspond one-to-one with equipment information in the resource information table via field IDs. And potential hazard equipment models correspond one-to-one with potential hazard information in the resource information table via field IDs.

[0064] The model library mainly stores and manages the relevant resource files required for system operation in the form of files. The dependencies between various resource files in the model library are usually uniformly planned and managed in the form of Json files and database property tables (indexes).

[0065] The simulation training support unit is the core of the system's development. Using the platform portal system as a unified access interface, it provides data and functional service interfaces. Users can use the functions provided by the simulation training support unit to complete related teaching, training, and assessment tasks. They can also utilize the interface functions retained by the simulation training support unit to complete operations such as data addition and user and permission management. The simulation training support unit dynamically configures scenarios based on the user's job type and a list of potential training hazards, generating training results based on actual training data.

[0066] The simulation training support unit is the core of the system, built on the .NET framework. It utilizes either the Microsoft.NET or Mono.NET runtime library, depending on the operating system and work environment of the user's existing server. The system's 3D scene browsing, interaction, and feature delivery are developed using Unity3D, a popular 3D virtual reality engine.

[0067] The simulation training support unit is the core of the system's functional modules, and all user interfaces are based on it. To ensure system flexibility, the independence of functional modules is maintained as much as possible during system design, and the coupling between modules is reduced.

[0068] The simulation training support unit includes a virtual scene reconstruction module, a user role and authority management module, an information explanation module, a collaborative teaching module, and a training result generation module.

[0069] The user role and permission management module supports administrators to configure user roles and permissions;

[0070] The virtual scene reconstruction module determines the virtual scene to be presented by the current system based on the user's job type and the list of hidden dangers to be trained. It uses the database unit and the model library unit to obtain the 3D model resource link, extracts the corresponding 3D model, dynamically loads it into the training scene, and binds the control logic to complete the virtual scene construction.

[0071] After the virtual scene is constructed in the information explanation module, the hidden dangers in the scene are explained, including the basis for determining the hidden dangers, the classification of the hidden dangers, and the hidden danger rectification measures;

[0072] The collaborative teaching module can simultaneously control the display content of each client and explain the selected hidden danger knowledge points;

[0073] The training result generation module generates training results based on the assessment data and displays them.

[0074] The application platform is built on the simulation training support unit and is divided into three parts based on user type: the system administrator module, the customer unit guidance module, and the student training module. Different modules can provide different functions.

[0075] The main functions of the system administrator module include: database unit configuration management, model library unit configuration management, and local server management. Database unit configuration management includes adding, reducing, modifying, and deleting various types of information. Model library unit configuration management includes adding, reducing, modifying, and deleting various models.

[0076] The main functions of the customer unit guidance module include: user management, hidden danger list configuration management, and assessment and scoring management.

[0077] The main functions of the student training module include: independent learning, virtual training, and virtual assessment.

[0078] The system's database, model library management, and Web service publishing functions are based on the software system's architecture and related software configuration solutions, and are updated and improved accordingly. The 3D model data involved is collected using on-site photos, created in 3ds Max, and stored in a unified format.

[0079] Both the system administrator module and the client unit guidance module are configured and service released on the web. This is intuitive and easy to manage, eliminating the need to log in to the executable program for dynamic configuration each time, improving system stability.

[0080] The simulation training support unit mainly performs dynamic scene configuration through the virtual scene reconstruction module based on the user's job type and the list of hidden dangers to be trained.

[0081] The virtual scene reconstruction module first determines the virtual scene to be represented by the current system and uses the resource information table stored in the database to obtain the 3D model ID content in the virtual scene. It then combines the scene resource ID stored in the database to obtain the corresponding 3D model resource link. Finally, the virtual scene is recreated by dynamically loading the 3D model into the virtual scene.

[0082] (1) Scene Content Acquisition. This system can adapt to different virtual scenes, which are composed of model resources and their locations. Resources are stored as files, and each resource is maintained in the database as a file link. Scene content acquisition involves obtaining a list of all resources in the scene and their locations and angles within the virtual scene. This operation can directly access the relevant data through the database.

[0083] (2) Resource index acquisition. The database unit stores the access link of each resource in the model library unit. The system obtains the index of the resource required by the scene based on the obtained scene content resource ID, and obtains the file access address of the corresponding resource through the index.

[0084] (3) Dynamic loading of resources. By obtaining the files of resources required for the scene, determine whether the current local client has the resource. If the resource exists locally, load the corresponding resource from the local client. If the resource does not exist locally, download the resource through the network and save the resource to the local folder so that it can be loaded directly from the local next time to improve the loading speed. After loading the resource into the scene, obtain the location of the resource in the scene and dynamically instantiate the resource to the specified location. When all resources are dynamically loaded to the specified location in the scene, the three-dimensional reproduction of the virtual scene is completed. The dynamic resource loading process is as follows: Figure 2 As shown, the details are as follows:

[0085] Determine whether the required model resources exist locally based on the ID information;

[0086] If so, load the corresponding model resource; otherwise, obtain the server location of the model library unit, download the model resource on the server, save it locally, and load the resource at the same time;

[0087] Repeat the above steps to traverse all required model resources and complete the dynamic loading of model resources into the scene.

[0088] (4) Scene logic linking. In addition to display functions, various resources dynamically loaded into the scene also have dynamic control requirements. They must be associated with the overall scene logic. The logic of individual resources must be bound to the control logic required for the overall scene training to achieve automatic monitoring of the learning, training, and assessment processes.

[0089] The collaborative teaching module controls the display content of each client and selects a specific knowledge point to focus on. During the teaching process, the model status displayed on each client and the viewing angle of each model can be controlled.

[0090] The network collaborative environment is built. The interaction between the controller and the client is controlled by network synchronization. All participating terminals are connected to the same network server, and the server is responsible for data distribution between the clients. This system uses the mature network server - Photon Server as the collaborative server. Its architecture is as follows Figure 3 This system uses the UDP protocol to synchronize network status between clients, reducing network bandwidth pressure while ensuring network timeliness.

[0091] Model state synchronization. During collaborative teaching, the model state explained by each client should be consistent, and the model state displayed by the client should be controllable. Since the model state only changes when the state is switched, this system uses RPC remote calls to synchronize the model state between different clients to improve network efficiency. RPC, which stands for Remote Procedure Call, is an inter-process communication method that allows a program to call a procedure or function in another address space (usually on another machine on a shared network) without the program explicitly encoding the details of the remote call.

[0092] Viewpoint synchronization. When an instructor is giving a lecture, the viewpoints of each client need to be aligned with the instructor's client so that users can understand what the instructor is saying. To achieve this, the virtual viewpoints of each client and the instructor need to be synchronized. The system uses a real-time synchronization solution to update the position and angle of the client's virtual viewpoint in real time.

[0093] The data flow of the present invention is as follows Figure 4 As shown, Figure 4 In the process, existing role and permission management data and safety hazard data are extracted from the database unit. Scenario content data is extracted based on the various safety production scene equipment components for local training. 3D modeling materials, 2D images, and audio and video data from various safety production scenarios are integrated and processed into 3D model files, texture files, and audio and video files. Assessment results are then used for training and display.

[0094] The simulation training support unit dynamically configures the scene through the web. The application platform receives the dynamic configuration information of the web scene, completes the construction of the virtual scene, and conducts teaching, learning, training and assessment.

[0095] A method for applying a dynamically configurable interactive training system comprises the following steps:

[0096] The administrator on the server side assigns roles and configures permissions for the client units that currently want to conduct interactive training;

[0097] The administrator of the client unit configures the list of hidden dangers to be trained for different types of work in the client unit on the client unit;

[0098] After the client's user logs in to the system, the system determines the virtual scene to be displayed by the current system based on the user's job type and the list of hidden dangers to be trained. It uses the database unit and model library unit to obtain the 3D model resource link, extracts the corresponding 3D model, dynamically loads it into the training scene, and binds the control logic to complete the virtual scene construction.

[0099] If the user selects the teaching mode, the user's perspective will be locked to the customer unit administrator's perspective. From the customer unit administrator's perspective, the system will explain the hidden dangers in the current virtual scene one by one, and teach the methods of troubleshooting and rectifying the hidden dangers.

[0100] If the user selects the learning mode, the user can click on the hidden danger on the interface to learn the content of the hidden danger and the rectification method; the hidden danger content includes the basis for determining the hidden danger and the classification of the hidden danger;

[0101] If the user selects the training mode, the user will roam autonomously in the virtual scene, find potential hazards in the virtual scene and make corrections. The system will display the current training progress in real time. During the training, the user can select the "Help" function to prompt the potential hazards that have not yet been discovered in the current virtual scene, and correct them one by one to complete the training.

[0102] If the user selects the assessment mode, the user will roam autonomously in the virtual scene, find potential hazards in the scene and make corrections within a limited time. After the assessment is completed, the system will record the assessment data and generate the assessment results.

[0103] The virtual scene construction process is as follows:

[0104] The virtual scene reconstruction module determines the virtual scene to be displayed by the current system based on the user's job type and the list of hidden dangers to be trained. It uses the resource information table in the database unit to obtain the scene model ID, normal equipment model ID, hidden danger equipment model ID, and worker model ID in the virtual scene to be displayed. It configures the resource ID on the web side and binds the above-mentioned various model resources with the control logic required for the overall virtual scene teaching, learning, training or assessment to generate a JSON file.

[0105] The student training module extracts model resources based on the JSON file resource information and dynamically loads them into the scene. After loading is completed, the position and angle of normal equipment and hidden danger equipment are configured according to the production status of the workshop, and the corresponding equipment is dynamically instantiated to the specified position to complete the three-dimensional construction of the virtual scene.

[0106] The process of extracting model resources based on JSON file resource information and dynamically loading them into the scene in the student training module is as follows:

[0107] Determine whether the required model resources exist locally based on the resource information in the JSON file;

[0108] If so, load the corresponding model resource; otherwise, obtain the server location of the model library unit, download the model resource on the server, save it locally, and load the resource at the same time;

[0109] Repeat the above steps to traverse all resource information in the JSON file and complete the dynamic loading of model resources into the scene.

[0110] In the present invention, each production field has a hidden danger resource library, which serves as a question bank for interactive training of client units. According to the training or assessment plan, the client unit administrator extracts content from the question bank and configures a list of hidden dangers to be trained for a certain type of work as training (teaching, learning, training) or assessment content.

[0111] Example:

[0112] The content of the present invention is explained by taking the application of the interactive training system of the present invention to realize the practical training of safety hazard identification and elimination in a certain unit as an example.
