Description

Technical Field

[0001] This invention relates to the field of virtual scene management technology, and in particular to a device and method for assessing and handling accident processes in virtual scenes. Background Technology

[0002] With the development of computer and process simulation technology, many domestic companies have established platforms capable of simulating real production processes in industries such as chemical engineering on computers, creating corresponding virtual factories (i.e., digital twins of the processes), simulating factory processes and control logic, and facilitating adjustments and training. For example, Aspen can perform steady-state process simulation, while Vxots can perform dynamic process simulation. Computer process simulation software such as Vxots can also realistically simulate factory start-up and shutdown, as well as various accident phenomena and handling procedures. Computer process simulation software can also be used as an OTS (Operator Training System) for training purposes. Current OTS systems are based on dynamic simulation technology, possessing accurate process equipment algorithm libraries, comprehensive material property databases, and control algorithm libraries consistent with those of various DCS manufacturers, ensuring that the developed models have high simulation accuracy and good dynamic response effects. In addition to accurate dynamic simulation technology, OTS systems can also be combined with 3D engines to achieve 2D and 3D linked operation and training, simulating various emergency accidents and emergency handling procedures. Ultimately, this achieves immersive operation simulation training that is not limited by time or location. In the application of emergency drills and training technology in this 3D scenario, the most common approach is to combine 3D animation with mouse interaction, which can achieve a relatively realistic training effect in a virtual environment.

[0003] However, dedicated software is needed for fire response, and similar software needs to be developed for other emergencies. Each time such dedicated software is developed, a 3D animation editing and development model is required to encapsulate the relevant emergency drill 3D animations within the platform. Technicians configure the software by assigning different parameter values ​​to achieve a coordinated effect between the overall operational logic and the animation content. Firstly, this development model is relatively rigid, and adjustments to animation effects require cross-departmental collaboration, resulting in high rework costs. Secondly, the inconsistent assignment of related parameters hinders rapid checking and adjustments, and the visual effects are not intuitive. Thirdly, while setting connection parameters for the completed animations simplifies the animation operation for emergency drill editors, it also introduces the drawback of inflexible animation configuration.

[0004] For example, patent application CN104219404A discloses a method for conducting emergency response drills for communication networks, including: generating a drill task tree based on a script of an emergency scenario selected by the user, wherein the emergency scenario is associated with IT systems and equipment; dispatching tasks from the root node to the leaf node of the drill task tree to the roles involved in the drill task tree; after receiving task completion messages from each role, traversing the executable tasks in the drill task tree according to the drill task tree and the dependencies of each task therein, and dispatching the executable tasks to the corresponding roles, until all tasks in the drill task tree have been executed.

[0005] Patent application CN108664502A discloses a timeline-based emergency drill script visualization and editing tool for 3D simulation of multi-department emergency drills. It includes a planning data generation module, a resource extraction module, a script generation module, and a visualization interface. The planning data generation module receives drill process information containing multiple drill contents, arranges all drill contents in chronological order using a preset timeline template, and generates drill planning data. The resource extraction module receives the drill planning data, extracts at least one drill resource from each drill content, imports it into a drill resource list, and outputs the drill resource list, where each drill resource has resource attribute data describing the drill resource. The script generation module receives the drill planning data and the drill resource list, configures the drill resources in the drill resource list into its internal timeline script based on the drill planning data, and generates the drill script. The visualization interface allows access to the planning data generation module, resource extraction module, and script generation module.

[0006] Patent application CN112184892A discloses a method for demonstrating emergency response plans using a 3D model, which includes the following steps: establishing a 3D scene based on the corresponding application requirements using JavaScript; parsing the entity types, particle parameters, and script animations in the 3D scene using a script parser; and demonstrating the emergency response plan in the 3D scene based on the parsing results of the script parser.

[0007] As shown above, existing technologies generally focus on the drill process in emergency scenarios, aiming to familiarize personnel with operational procedures in such scenarios, but neglecting the assessment of whether individuals perform adequately during the drills. In other words, these existing technologies either ignore or are unable to evaluate the specific actions of personnel during emergency operations. Without assessment, it is impossible to know whether personnel's actions in emergency scenarios are correct, thus preventing the emergency drills from achieving their intended effect.

[0008] This invention aims to provide an apparatus and method for assessing accident process handling in virtual scenarios, thereby enabling the assessment of emergency drills in virtual scenarios, helping digital twin factories to conduct emergency drills and provide assessment results, and thus correcting unqualified steps in the process.

[0009] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making this invention, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that the present invention does not possess the features of these prior art. On the contrary, the present invention already possesses all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art. Summary of the Invention

[0010] Existing emergency training systems focus on procedural training for staff, aiming to increase their familiarity with emergency procedures while neglecting the assessment of individual staff emergency response capabilities. This leads to staff mechanically implementing emergency response behaviors during training, ignoring the nuances of an accident and resulting in less-than-ideal outcomes. Furthermore, existing systems neglect assessing individuals' emergency response capabilities, failing to place highly capable individuals in more appropriate roles. When evaluating accident handling results as a group, the fact that some employees lacked proper emergency response procedures can be masked by the overall correctness of the group's actions. In a real accident, employees unfamiliar with emergency response procedures may cause the situation to escalate uncontrollably. Therefore, it is essential to assess whether staff have truly mastered correct emergency response procedures.

[0011] To enhance the emergency response capabilities of different groups, including emergency management personnel and emergency rescue personnel, existing technologies have emerged that attempt to evaluate the effectiveness of emergency drills by constructing emergency drill training systems. For example, patent document CN114020185A discloses an emergency drill training system and its construction method. The specific construction method includes: constructing multiple emergency scenarios; constructing a front-end system for conducting multi-person collaborative drills; constructing an emergency drill guidance platform for configuring emergency drill information; and constructing a comprehensive evaluation method for evaluating the effectiveness of emergency drills. The resulting emergency drill training system enables multiple users to conduct immersive training drills simultaneously and comprehensively evaluate the drill results. This technical solution provides a platform for emergency decision support, drill training, and scientific research support from a virtual-real integrated perspective, thereby improving emergency command and decision-making capabilities, team combat capabilities, and public self-rescue and mutual rescue capabilities. However, this technical solution can only evaluate the performance of the examinee according to the training script based on pre-packaged operational actions, and cannot accurately evaluate the examinee's performance beyond the training script or in situations where the training script is temporarily modified. Furthermore, the assessors of this technical solution can only evaluate the examinee's performance in emergency drills through a viewing module, and cannot adjust or modify the specific training script, thus failing to achieve a true evaluation of emergency response capabilities in the face of emergencies and failing to reflect the examinee's objective emergency response capabilities. This invention provides, from a first aspect, an accident process handling assessment device in a virtual scenario, including a processor, a first terminal used by the assessor, and a second terminal used by the examinee. The processor establishes data connections with the first and second terminals respectively. The processor constructs an accident process image in a three-dimensional scene according to a preset editing script; the first terminal, based on the operational behavior information fed back by the second terminal, retrieves parameter adjustment information, accident process change information, and / or interference test information related to the accident process image from the processor in real time to adjust the assessment information. The second terminal displays the accident process image and its assessment information in the three-dimensional scene, and feeds back the examinee's operational behavior information to the processor. The processor extracts assessment elements from operational behavior information and compares them with the operational standard behaviors corresponding to the accident process in order to analyze and obtain assessment results.

[0012] Compared with the prior art, the assessment device in this invention can adjust subsequent assessment information based on the specific operational behavior of the assessment subject. Based on these distinguishing technical features, the problem this invention aims to solve can include: how to establish an editable accident process assessment model to achieve a comprehensive and accurate evaluation of the assessment subject's emergency response and handling capabilities. Existing technologies can only display the accident process according to preset script information, making the accident process unchangeable and unable to be altered based on the assessment subject's operational behavior. This invention addresses the shortcomings of existing technologies by improving the assessment mechanism for assessment personnel, enabling the three-dimensional accident process to actively or passively change based on the assessment subject's operational behavior, previous assessment failures, or new safety documents, thereby assessing the personnel's emergency response and handling capabilities from multiple perspectives. Based on the assessment results, this invention can also select individuals with strong emergency response capabilities to form emergency response teams, thereby improving the accident handling capabilities of emergency departments within industrial plants and reducing safety risks in industrial parks.

[0013] To address the limitations of conventional emergency drill systems, such as the monotony of drill content and the inability to adjust assessment content in real-time during evaluations, existing technologies have developed solutions that allow for the editing of drill content. For example, patent document CN116259206A discloses an emergency drill system based on VR technology, comprising a student terminal and an instructor terminal, electrically connected. The student terminal provides emergency drill training to students, while the instructor terminal provides training content management, multimedia resource management, training course assignment summary analysis, and individual job assignment summary analysis for instructors. Specifically, the training content management includes classifying, grading, adding, updating, and deleting drill content. Users can classify and grade training content themselves, and can add, update, and delete training content at any time, as well as adjust the order of training task steps. While this technical solution can adjust specific training content, its purpose is to adapt to the actual assessment requirements of different trainees. This adjustment usually occurs before changing trainees, meaning that during the actual assessment process, this technical solution cannot temporarily modify the adjusted training content based on different trainees, and therefore cannot accurately evaluate the emergency response and handling capabilities of the assessed individuals. Compared to the prior art, the first terminal in this invention can retrieve parameter adjustment information, accident process change information, and / or interference test information related to the accident process image from the processor in real time based on the operational behavior information fed back by the second terminal, thereby adjusting the assessment information in real time. Based on the above distinguishing technical features, the problem to be solved by this invention can include: how to adjust the corresponding assessment information according to changes in the operational behavior of the assessed individuals. Specifically, taking various emergencies occurring in a factory as examples of accidents requiring emergency handling, different handling methods by the assessed individuals in the current state will lead to different subsequent accident process changes. For example, a fire in a factory is a sudden accident. Whether its specific direction of spread points to flammable and explosive hazardous materials represents two different accident processes. Different handling methods by the assessed individuals will lead to different secondary accidents. Emergency response to secondary accidents is also part of the overall assessment of the assessed individuals, and it is an effective way to accurately reflect their true emergency response capabilities. This invention grants assessors the right to modify assessment information through a first terminal, allowing them to change factors such as the accident scenario, environment, and development trend based on the characteristics of the assessed individuals. This further assesses the assessed individuals' emergency response, rationality in emergency situations, and attentiveness on top of the basic assessment, obtaining assessment results that better reflect human characteristics. Therefore, it assesses the personnel's emergency response capabilities from multiple perspectives.

[0014] According to a preferred embodiment, the processor adjusts the operating parameters of the accident object and / or several devices associated with the accident object in a three-dimensional scene based on the working attributes, natural attributes and / or safety attributes of the assessment object, and displays the operable categories related to the current accident process in a pop-up manner through a first terminal. In response to the specified operable categories fed back by the first terminal, the processor adds test information corresponding to the operable categories in the three-dimensional scene.

[0015] Compared to the prior art, the processor of this invention can adjust relevant accident process parameters according to different information of the assessment subject. Based on the above-mentioned distinguishing technical features, the problem to be solved by this invention can include: how to improve the comprehensiveness of the assessment information in evaluating the emergency accident handling and emergency response capabilities of the assessment subject. Compared to the existing assessment methods that only allow viewing of the accident process, this invention allows assessors to participate in the assessment by modifying the accident process at any time, enabling the three-dimensional accident process to develop in a diversified manner, so as to fully assess the personnel's proficiency in safety regulations and emergency handling procedures. Because the accident process of this invention is variable, the assessment subject will not develop a fixed test-taking operation effect due to the increase in the number of assessments. This invention is more able to obtain the actual emergency response and emergency operation behavior of the assessment subject through assessment.

[0016] According to a preferred embodiment, the processor adjusts the incident process in the 3D scene based on the historical score loss characteristics of the assessment object; and / or the processor adjusts the incident process in the 3D scene based on the last updated safety specifications and / or incident files.

[0017] Adjusting the accident process based on the characteristics of previous assessments and the latest safety regulations and documents is beneficial for confirming whether trainees have mastered the new safety precautions after the new safety training is completed.

[0018] According to a preferred embodiment, in response to the operator's instructions, the first terminal sends environmental parameter information to the processor in real time based on the operator's behavior information. The processor adaptively adjusts the accident process in the 3D scene based on the environmental parameter information to test the operator's behavior. Compared with the prior art, the processor of the present invention can adjust the accident process in the 3D scene according to the impact of the operator's specific behavior on the environmental parameter information. Based on the above-mentioned distinguishing technical features, the problem to be solved by the present invention may include: how to accurately reflect the impact of the operator's behavior on the accident process. For example, when a fire occurs locally in a factory, the temperature in the surrounding environment will change. This change will affect the parameter changes of nearby equipment or processes, which may lead to new emergencies. If the operator handles the sudden fire and eliminates the possibility that the fire will cause changes in environmental parameters that affect the parameters of nearby equipment or processes, the assessment process will not produce new emergencies. Therefore, it is necessary to use the impact of the operator's behavior information on the environmental parameter information as an adjustment element of the accident process in the 3D scene to achieve a more accurate assessment effect. Furthermore, by altering environmental parameters during the accident process, this invention changes the precautions for handling the accident, thus enabling safety assessments of personnel from a detailed perspective, making the assessments more diverse.

[0019] According to a preferred embodiment, in response to an operator's instruction based on the operational behavior of the assessment subject, the first terminal sends interference test information to the second terminal in real time or performs interference operations. This configuration, using real operations as interference test information, makes the simulated scenario more realistic, which is beneficial for assessing the ability to distinguish between false information or erroneous instructions, thereby obtaining accurate assessment results.

[0020] According to a preferred embodiment, the operational behavior information fed back to the processor by the second terminal includes: reporting behavior, recording behavior, and processing behavior associated with time stamps. Unlike existing technologies that can only feed back processing behavior, this invention can record the actual operations of the assessment subject, improving the accuracy of the assessment results.

[0021] According to a preferred embodiment, in response to received interference test information, the second terminal displays options for operable categories corresponding to the interference test information, so that the subject can control the simulator to perform operational actions under interference conditions. The advantage of this configuration is that it reduces the amount of data transmission between the second terminal and the first terminal or processor, enabling the second terminal to quickly make assessment adjustments based on the interference test information, thereby improving the efficiency of accident process handling assessments in virtual scenarios.

[0022] According to a preferred embodiment, when viewing the simulated human's operational behavior in a 3D scene via a first terminal, the first terminal displays several modifiable and / or insertable accident scenario options based on the operational behavior, allowing the assessor to select an accident scenario at any time to change the accident process. If no accident scenario selection information is received, the processor sets the accident process in the 3D scene to change normally according to a preset editing script. This setting reduces the assessor's thinking time during the viewing process, enabling them to quickly select an accident scenario to change the accident process. If the assessor deems it unnecessary to add or change the accident scenario, it will not affect the assessment.

[0023] The present invention also discloses, in a second aspect, a method for assessing accident process handling in a virtual scene. The method includes: constructing an accident process image in a three-dimensional scene according to a preset editing script; retrieving parameter adjustment information, accident process change information, and / or interference test information related to the accident process image in real time based on the operational behavior information fed back by the assessment subject, so as to adjust the assessment information in real time; displaying the accident process image and its assessment information in the three-dimensional scene, and recording the operational behavior information of the assessment subject; extracting the assessment elements from the operational behavior information and comparing them with the operational standard behavior corresponding to the accident process, so as to analyze and obtain the assessment result.

[0024] Compared with existing technologies, the advantage of the method of the present invention is that the accident process and assessment information are diversified, so that the assessment subjects will not participate in the test in the same scenario and obtain real and accurate assessment results.

[0025] According to a preferred embodiment, the method further includes: adjusting the operating parameters of the accident object and / or several devices associated with the accident object in a three-dimensional scene based on the work attributes, natural attributes, and / or safety attributes of the assessment subject; displaying operable categories related to the current accident process in a pop-up manner; and adding test information corresponding to the operable category in the three-dimensional scene in response to the specified operable category. Existing examination systems do not differentiate between the work attributes, natural attributes, and safety attributes of the assessment subject; that is, everyone uses the same accident process scenario. The drawback of this assessment is that the safe operations and safety regulations that each person needs to master in real production are different. A uniform assessment results in individuals possessing many safety regulations that they are not authorized to implement in emergencies, which not only reduces the importance people attach to the assessment but also leads to more ineffective assessments. This invention provides targeted assessments based on an individual's work attributes, natural attributes, and safety attributes, making the assessment scenario more focused on operations that align with the individual's identity and functional scope, and promoting the assessment subject's proficiency in safe operating behaviors usable in emergency scenarios.

[0028] List of reference numerals

[0029] 10: Processor; 20: First terminal; 30: Second terminal. Detailed Implementation

[0030] The following is a detailed explanation with reference to the accompanying drawings.

[0031] Digital Twin Factory: The digital twin factory is the foundation of this invention. In this invention, the three-dimensional scene of the digital twin factory is consistent with the physical equipment within the factory, making it more suitable as a training and assessment scenario. This allows the test subjects to more easily immerse themselves in the assessment scenario and more easily implement routine training operations.

[0032] A script is an executable file written according to a specific format. Scripts are used to control software applications. In this invention, the script for the accident process in the 3D scene is pre-set in the processor. Unlike existing technologies, the accident scenario in this invention, consisting of the accident scope, accident location, accident cause, and accident equipment, can be modified by the assessor.

[0033] Assessors: refers to the personnel responsible for assessment at the first terminal 20. The assessment in this invention can be divided into an automatic assessment mode and a collaborative assessment mode. The automatic assessment mode refers to an assessment mode in which the assessment process does not require the intervention of assessors. The collaborative assessment mode refers to an assessment mode in which the assessors at the first terminal 20 participate in the accident process by changing objective environmental parameters, accident details, and inputting interference test information. Compared to the single and one-sided automatic assessment mode, the collaborative assessment mode can conduct more flexible assessments of the assessed objects based on the automatic assessment mode, making the assessment more diverse and non-repetitive, reducing the drawbacks of test-taking effects, and obtaining more realistic assessment results.

[0034] The assessment target refers to the staff member being assessed.

[0035] Processor 10: A dedicated integrated chip, server, server cluster, and cloud server capable of executing the coding program of the present invention for the accident process handling assessment method in a virtual scenario.

[0036] First Terminal 20: Used by the assessors. First Terminal 20 is used to display the accident process in the 3D scene and the operational behavior of the assessors within the 3D scene. First Terminal 20 is, for example, an electronic device with display capabilities and human-computer interaction. Examples of electronic devices include smart terminals, computers, tablets, various large-scale computers, etc.

[0037] Second terminal 30: Used by the assessment subject (the person being assessed). Second terminal 30 is used to display the accident process in a 3D scene and record the assessment subject's operational behavior. Second terminal 30 is, for example, an electronic device with display capabilities and human-computer interaction. Electronic devices include, for example, communication terminals, computers, tablets, various large computers, etc. Generally, second terminal 30 includes communication functions, display functions, and human-computer interaction functions. Preferably, second terminal 30 can also be configured as a combination of a mobile communication terminal and a smart display terminal.

[0038] Job attributes refer to information related to the job, including job information, job functions, work activity area, working hours, and other positions that have a direct management relationship with this job position.

[0039] Natural attributes refer to a person's basic information, including height, age, gender, ethnicity, nationality, education, and alma mater.

[0040] Safety attributes refer to information such as the safety level corresponding to one's job position and the safe operating procedures that should be mastered.

[0041] Example 1

[0042] Existing technologies can only display the accident process according to preset script information, making the accident process unchangeable and unable to be altered based on the operational behavior of the person being assessed. This invention addresses the shortcomings of existing technologies by improving the assessment mechanism for assessors. It allows the three-dimensional accident process to actively or passively change based on the operational behavior of the assessed individual, previous assessment failures, or new safety documents, thereby assessing the personnel's emergency response and handling capabilities from multiple perspectives. Based on the assessment results, this invention can also select individuals with strong emergency response capabilities to form emergency response teams, thereby improving the accident handling capabilities of emergency departments within industrial plants and reducing safety risks in industrial parks.

[0043] like Figure 1 As shown, the accident process handling assessment device for a virtual scenario of the present invention includes a processor 10, a first terminal 20 used by the assessor, and a second terminal 30 used by the assessee. The processor 10 establishes data connection relationships with the first terminal 20 and the second terminal 30, respectively.

[0044] The operating principle of the device of the present invention is as follows: the processor 10 executes the accident process in a three-dimensional scene based on a preset editing script. Preferably, the three-dimensional scene of the processor 10 is a three-dimensional virtual scene set up based on a digital twin factory, with the same equipment distribution and building layout as the real factory where the assessment subject is located. This can eliminate the unfamiliarity of the assessment subject, enabling the assessment subject to quickly take corresponding operational actions based on daily experience. The first terminal 20 receives and displays the accident process of the three-dimensional scene sent by the processor 10. During the display process, the first terminal 20 changes or inserts accident plots based on the operation instructions input by the assessment subject. The second terminal 30 displays the accident process of the three-dimensional scene sent by the processor 10. The second terminal 30 also records the operation behavior information of the assessment subject.

[0045] The processor 10 constructs an accident process image in a 3D scene according to a preset editing script and sends it to the first terminal 20 and the second terminal 30 respectively. Specifically, the processor 10 determines the specific area of ​​the 3D scene of the assessment object based on the assessment object's work attributes, natural attributes, and / or safety attributes. This enables the assessment object to perform operational actions in a scene familiar to them in their daily work.

[0046] The first terminal 20 receives the three-dimensional scene and its accident process sent by the processor 10, and displays the operating behavior of the simulated human controlled by the test subject. For example... Figure 2 As shown, in a three-dimensional scene, the simulated human moves and performs operations based on the control of the test subject.

[0047] The second terminal 30 receives the three-dimensional scene and its accident process sent by the processor 10, and displays several operational behaviors that the simulated human can perform. After the subject selects an operational behavior, the simulated human performs the corresponding operational behavior. During the assessment, the second terminal 30 feeds back the operational behavior selected by the subject to the processor 10, so that the first terminal 20 and the second terminal 30 can synchronously display the simulated human's operational behavior.

[0048] Preferably, the operational behavior information fed back from the second terminal 30 to the processor 10 includes: reporting behavior, recording behavior, and processing behavior associated with time stamps. Unlike existing technologies that can only feed back processing behavior, this invention can comprehensively record the actual operations of the assessment subject, improving the accuracy of the assessment results. The processor 10 establishes a sequential relationship between each accident scenario and the operational behavior of the assessment subject based on time information, thereby recording the assessment subject's safe operational behavior in response to the accident scenario. For example, when the pressure of a certain piece of equipment is abnormal, the assessment subject should inspect nearby equipment and record its operating status. If the assessment subject inspects the equipment but does not select the recording behavior, the assessment subject is considered to have missed recording behavior. When the temperature of a certain piece of equipment is abnormal, the assessment subject should record the temperature information and report it to the team leader. If the assessment subject only reports the abnormal situation to the team leader (e.g., making a phone call using a designated mobile communication device) but does not record the temperature information, then the assessment subject is also considered to have missed recording behavior. If the assessment subject should also close the valve but does not control the simulator to perform the corresponding operation, then the assessment subject is considered to have lacked the corresponding operational behavior.

[0049] Unlike the traditional assessment system of existing technologies, the first terminal 20 of this invention enables assessment personnel and the assessment system to collaboratively assess the assessment object.

[0050] For example, the first terminal 20 retrieves parameter adjustment information, accident process change information and / or interference test information related to the accident process image from the processor 10 in real time based on the operation behavior information fed back by the second terminal 30, so as to adjust the assessment information in real time.

[0051] Parameter adjustment information includes equipment parameter adjustment information, environmental parameter adjustment information, and time parameter adjustment information. For example, in collaborative assessment mode, equipment parameters in a 3D scene can be adjusted to put the equipment into an accident state, the direction of flame spread at the ignition point can be adjusted through parameters, the ignition point can be changed, and materials near the ignition point can be changed, etc. Adjustments to equipment and environmental parameters cause changes to the required operational behaviors.

[0052] Information on changes in the accident process refers to changes in the circumstances of the accident. For example, whether the direction of the fire's spread points towards flammable and explosive hazardous materials represents two different accident processes.

[0053] Interference test information refers to information that is disruptive to the test subject. Interference test information includes not only distracting options on the display interface but also real communication information. For example, an assessor, posing as a team leader, might call the test subject and instruct them to perform a specific operation. The test subject needs to consider whether the instruction is correct and whether it should be executed.

[0054] This invention grants assessors the right to modify assessment information through a first terminal 20, enabling them to alter elements such as the accident scenario, accident environment, and accident development trend based on the characteristics of the assessed individual. This allows assessors to further evaluate the assessor's emergency response, rationality in emergency situations, and attentiveness on top of the basic assessment, thereby obtaining assessment results that better reflect human characteristics.

[0055] For example, when viewing the simulated human's actions in a 3D scene through the first terminal 20, the first terminal 20 triggers (e.g., pops up) several modifiable and / or insertable accident scenario options based on the assessment subject's actions, allowing the assessor to select an accident scenario at any time to change the accident process. If no accident scenario selection information is received, the processor 10 sets the accident process in the 3D scene to change normally according to a preset editing script. This setting reduces the assessor's thinking time during the viewing process, allowing them to quickly select an accident scenario to change the accident process. If the assessor feels that adding or changing the accident scenario is unnecessary, it will not affect the assessment process.

[0056] Preferably, the modifiable and / or insertable incident scenario options can also be triggered by the first terminal 20 based on the progress of the incident process, without being sent by the processor 10. The advantage of this approach is that it reduces the amount of data transmission between the processor 10 and the first terminal 20. During the assessment, the processor 10 runs the assessment program for the 3D scene and records the actions of the assessors, which involves a significant amount of computation. Having the program encoding of the modifiable and / or insertable incident scenario options run by the first terminal 20 helps reduce the data processing load of the processor 10 and the amount of data transmission between it and the first terminal 20, maintaining a smooth demonstration of the 3D scene incident process and avoiding insufficient clarity or screen stuttering in the 3D scene.

[0057] Modifiable and / or insertable incident scenario options include, for example, inserting another ignition point at a distance from the equipment experiencing abnormal temperature. Flammable materials are present in the vicinity of this ignition point. In this case, whether the subject of the assessment first checks the equipment with abnormal temperature or first extinguishes the ignition point is also considered as an operational behavior being assessed.

[0058] Preferably, the first terminal 20 triggers modifiable and / or insertable incident scenario options based on keywords in the call content of the person being assessed, allowing the assessor to select. This setting facilitates the assessor's comprehensive understanding of the person being assessed and allows for the insertion of incident scenarios, increasing the variability of the incident process and enabling the assessment of the person being assessed from a management perspective.

[0059] Preferably, after the modifiable and / or insertable incident plot options displayed on the first terminal 20 are selected, the first terminal 20 sends the code corresponding to the modifiable and / or insertable incident plot to the processor 10 so that the processor 10 adjusts the incident process based on the code, and the second terminal 30 synchronously displays the changes in the incident process of the three-dimensional scene, thereby reducing the amount of data transmission of the processor 10.

[0060] Preferably, before the assessment begins, the processor 10 adjusts the operating parameters of the accident object and / or several devices associated with the accident object in the three-dimensional scene based on the working attributes, natural attributes and / or safety attributes of the assessment object, and displays the operable categories related to the current accident process in a pop-up manner through the first terminal 20.

[0061] For example, the accident process of routinely contacting equipment can be displayed based on the identity of the security department team members, their corresponding daily work scope, and security level. After the assessment subject selects an operable category, the simulator will perform the corresponding operation in a 3D scene. In this way, the processor 10 not only records the operation behavior of the assessment subject, but also allows the assessment personnel at the first terminal 20 to clearly see the operation behavior through the simulator. Compared with traditional text information display methods, the operation behavior of the simulator is easier to observe and less likely to be missed, which is more conducive to the assessment personnel selecting accident scenario options based on the operation behavior.

[0062] In response to the specified operable category feedback from the first terminal 20, the processor 10 adds test information corresponding to the operable category in the three-dimensional scene.

[0063] Operable categories include, for example, operating equipment, recording, and reporting. After the first terminal 20 provides feedback on the operable category, the processor 10 retrieves the corresponding test information from the database and displays the test information by modifying or inserting accident scenarios. The advantage of this setup is that it allows test information to be set based on the needs of the assessors, enabling the selection of necessary emergency management personnel through assessment.

[0064] The processor 10 extracts the assessment elements from the operational behavior information and compares them with the operational standard behaviors corresponding to the accident process in order to analyze and obtain the assessment results.

[0065] Specifically, assessment elements refer to the key indicators of assessment, including the sequence of operational actions corresponding to the accident circumstances, the operational actions performed, and the operational actions omitted.

[0066] Compared to existing assessment methods that only allow viewing the accident process, this invention allows assessors to participate in the assessment by modifying the accident process at any time. This diversifies the three-dimensional accident process, enabling a comprehensive assessment of personnel's proficiency in safety regulations and emergency response procedures. Because the accident process in this invention is variable, the assessment subjects will not develop a fixed test-taking behavior with repeated assessments. This invention is more effective in obtaining the assessment subjects' actual emergency responses and operational behaviors.

[0067] Preferably, the processor 10 adjusts the incident process in the 3D scene based on the historical score loss characteristics of the assessment object. The processor 10 adjusts the incident process in the 3D scene based on the last updated safety specifications and / or incident files.

[0068] Adjusting the accident process based on the characteristics of previous assessments and the latest safety regulations and documents is beneficial for confirming whether trainees have mastered the new safety precautions after the new safety training is completed.

[0069] Preferably, in response to the operator's instructions, the first terminal 20 sends environmental parameter information to the processor 10 in real time based on the operator's behavior information. The processor 10 then adaptively adjusts the accident process in the three-dimensional scene based on the environmental parameter information to test the operator's behavior. This invention alters the precautions for handling the accident process by changing the environmental parameters during the accident, thus enabling more detailed safety assessments and making the assessments more diverse.

[0070] Preferably, in response to the operator's instructions based on the operator's behavior, the first terminal 20 sends interference test information to the second terminal 30 in real time or performs interference operations. This setup uses real operations as interference test information, making the simulated scenario more realistic and facilitating the assessment of the ability to distinguish between false information or erroneous instructions, thereby obtaining accurate assessment results.

[0071] Preferably, in response to the received interference test information, the second terminal 30 displays options for the operable categories corresponding to the interference test information, so that the test subject can control the simulator to perform operational actions under interference conditions. The advantage of this configuration is that it reduces the amount of data transmission between the second terminal 30 and the first terminal 20 or processor 10, enabling the second terminal 30 to quickly make assessment adjustments based on the interference test information.

[0072] The present invention also discloses, in a second aspect, a method for assessing accident handling in a virtual scenario, the method comprising:

[0073] S1: Construct images of the accident process in a 3D scene according to a preset editing script.

[0074] S2: Based on the operational behavior information fed back by the assessment subjects, retrieve parameter adjustment information, accident process change information and / or interference test information related to the accident process images in real time to adjust the assessment information in real time.

[0075] S3: Displays images of the accident process in a 3D scene and its assessment information, and records the operational behavior information of the assessment subject.

[0076] S4: Extract the assessment elements from the operational behavior information and compare them with the operational standard behaviors corresponding to the accident process in order to analyze and obtain the assessment results.

[0077] Compared with existing technologies, the advantage of the method of the present invention is that the accident process and assessment information are diversified, so that the assessment subjects will not participate in the test in the same scenario and can obtain real and accurate assessment results.

[0078] Preferably, based on the work attributes, natural attributes, and / or safety attributes of the assessment subject, the operating parameters of the accident object and / or several devices associated with the accident object are adjusted in a 3D scene during the accident process, and the operable categories related to the current accident process are displayed in a pop-up manner. In response to the specified operable categories, test information corresponding to the operable categories is added to the 3D scene. Existing examination systems do not differentiate between the work attributes, natural attributes, and safety attributes of the assessment subject; that is, everyone uses the same accident process scenario. The drawback of such assessment is that the safe operations and safety regulations that each person needs to master in real production are different. A uniform assessment results in individuals mastering many safety regulations that they are not authorized to implement in emergencies, which not only reduces the importance people attach to the assessment but also leads to more ineffective assessments. This invention provides targeted assessments based on an individual's work attributes, natural attributes, and safety attributes, making the assessment scenario more focused on operations that align with the individual's identity and functional scope, and promoting the assessment subject's proficiency in safe operating behaviors usable in emergency scenarios.

[0079] Preferably, the processor 10 adjusts the incident process in the 3D scene based on the historical score loss characteristics of the assessment object. The processor 10 adjusts the incident process in the 3D scene based on the last updated safety specifications and / or incident files.

[0080] In response to the operator's instructions, the first terminal 20 sends environmental parameter information to the processor 10 in real time based on the operator's behavior. The processor 10 adaptively adjusts the accident process of the 3D scene based on the environmental parameter information to test the operator's behavior.

[0081] In response to the operation instructions given by the assessor based on the operation behavior of the assessee, the first terminal 20 sends interference test information to the second terminal 30 in real time or performs interference operation.

[0082] In response to the received interference test information, the second terminal 30 displays the operable category options corresponding to the interference test information, so that the test subject can control the simulator to complete the operation under the interference state.

[0083] While viewing the handling of an accident in a 3D scene via the first terminal 20, the first terminal 20 displays several modifiable and / or insertable accident scenario options based on the assessment subject's operational behavior, allowing the assessment personnel to select an accident scenario at any time to change the accident process. If no accident scenario selection information is received, the processor 10 sets the accident process in the 3D scene to change normally according to a preset editing script.
