Description

Technical Field

[0001] The present invention belongs to the technical field of building safety training, and in particular relates to a VR interactive height operation safety training method and system. Background Art

[0002] In construction, there are many operations at heights. The so-called high-altitude operations refer to any operations that are performed at a height of more than 2 meters from the falling height reference plane, which may result in a fall. Since the high-altitude operations have a small activity surface, are surrounded by air, have strong winds, and involve many vertical cross operations, it is a very complex and dangerous job. Any negligence will result in serious accidents. High-altitude operations must strictly comply with the "Technical Specifications for Safety of High-altitude Operations in Construction".

[0003] Falling from heights, electric shock, being hit by objects, mechanical injuries and collapse are the most common accidents in the construction industry. They are called the "five major injuries" in construction. Accidents in these five areas account for more than 85% of the total accidents each year, of which falling from heights accounts for about 35%. Generally, working on a surface higher than 2 meters is called working at height. Working at a height without a reliable foothold is also called working in the air. When working at height, falling from heights must be prevented. Cross-operation refers to construction at the same time above and below, which is the main cause of accidents caused by being hit by objects. Efforts to improve the safety quality of the majority of practitioners and ensure that they do not harm others, do not harm themselves, and are not harmed by others are urgent issues that need to be addressed.

[0004] For the digital high-altitude work safety simulation experience method, the existing technical methods can only display the selection results and promote safety knowledge by playing 3D CG images after selecting options. The actual learners have low sense of participation and cannot simulate the real high-altitude work scene well. Some are just environmental simulations, and options are selected according to the process. The operation process of the simulation experience cannot be systematically and professionally scored and evaluated, thereby failing to deepen the learning effect of the simulation experience drills and the understanding of the hazards of accidents. Summary of the invention

[0005] The present invention provides a VR interactive height operation safety training method and system, which is used to solve the problem that in the existing technology, the consequences of illegal operations can only be experienced through VR, and scene demonstrations can be viewed from the first person, but scene interaction cannot be immersively performed to enhance the drill experience, and the operation process of the simulation experience cannot be systematically and professionally scored and evaluated, thereby failing to deepen the learning effect of the simulation experience drill and the understanding of the harmfulness of accidents.

[0044] In order to make the purpose, technical scheme and advantages of the present invention clearer, the technical scheme of the present invention will be described in detail below. It should be understood that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0045] In view of the fact that currently only the consequences of illegal operations can be experienced through VR in the related art, and the scene demonstration can be watched from the first person perspective, but the scene interaction cannot be performed immersively to improve the drill experience, and the operation process of the simulation experience cannot be systematically and professionally scored and evaluated, thereby failing to deepen the learning effect of the simulation experience drill and the understanding of the hazards of accidents, the present invention provides a VR interactive high-altitude operation safety training method and system;

[0046] Figure 1 A structural diagram of a VR interactive high-altitude work safety training method and system provided for an embodiment of the present application, including an information entry module, a training module, an information database module, a three-dimensional simulation module and an assessment module; the information database module is respectively connected to the training module and the three-dimensional simulation module, and is used to provide data support for the training module and the three-dimensional simulation module;

[0047] The specific implementation steps of this application are as follows:

[0048] Obtain the basic data of the experience user, confirm the basic information and account ID of the experience user, and build a related user system.

[0049] Preferably, the information of the experience user is entered according to a preset information entry mode, including:

[0050] Information of the experience user entered through manual input mode;

[0051] Use the electronic QR code scanning mode to input the experience user's information;

[0052] The information of the experienced users is entered through the batch import mode of Excel spreadsheet.

[0053] Preferably, the three-dimensional simulation module is used to simulate the scene of the high-altitude operation VR simulation experience system.

[0054] The main interface has three main options: drill training, knowledge question bank, and simulation drill. Experience users can interactively select to enter the corresponding operation sub-interface;

[0055] In this embodiment, enter the drill training sub-interface, select and enter the corresponding training item in the interface, play the relevant 3D video screen and explanation, including:

[0056] Selection and use of safety equipment involved in the hazard database;

[0057] In the fall prevention measures, equipment such as safety nets and guardrails should be reasonably set up;

[0058] Learning about safety signs and warning signs;

[0059] Related on-site environmental inspections in the hidden danger database;

[0060] The consequences of dangerous behaviors such as people working under the influence of alcohol or working while fatigued;

[0061] When working outdoors, choose safety measures in different weather and climate conditions.

[0062] The hidden danger database contains hidden danger information of walking at heights, hanging in the air, falling from heights, helmet collisions, scaffolding dismantling, construction elevators, lifting hazards, and tower crane collapses. When entering the system, in addition to the description of the hidden danger content, it is necessary to clearly define the category of walking at heights, hanging in the air, falling from heights, helmet collisions, scaffolding dismantling, construction elevators, lifting hazards, and tower crane collapses involved. At the same time, it should be clear that the coordination of supporting equipment such as sound and light involved in the interactive experience. This supports the interactive training learning and assessment of subsequent training modules and three-dimensional simulation modules;

[0063] Among them, the high-altitude walking experience uses VR virtual technology to simulate external forces, vision, hearing and other factors, allowing the experiencer to "personally experience" the feeling of high-altitude work on a virtual and realistic construction entity model site;

[0064] At the same time, a large screen device is set up to display the construction site and publicize videos of prevention-related knowledge and emergency measures. A hanging basket device and other protective facilities related to high-altitude operations are added in front of the large screen. Experiencers can ride in the hanging basket and wear safety belts to simulate the scene of walking in the air and feel the hazards of high-altitude operations;

[0065] Among them, the hanging experience of stepping on air is achieved by building a physical model of stepping on air. The experiencer climbs onto the physical model, ties a safety rope and experiences it. By tightening and pulling the safety rope, the experiencer crosses the working surface and directly experiences the hanging state and psychological tension caused by stepping on air.

[0066] At the same time, relying on scenario simulation, participants can learn how to wear safety ropes correctly and understand the importance of safety ropes in construction operations.

[0067] Among them, the high-altitude falling experience uses a physically built high-altitude falling platform to simulate an accidental fall, allowing the experiencer to fall unexpectedly without preparation;

[0068] At the same time, the importance of seat belts is reinforced once again;

[0069] Among them, the helmet impact experience aims at the common object impact accidents in construction sites. By simulating the impact scenes and consequences of falling objects on the helmets, the experiencers can understand the protective role of the helmets.

[0070] Among them, the scaffolding dismantling and erection experience, through a one-to-one scaffolding construction, the scaffolding construction scene is restored in real life, divided into two construction methods, correct and incorrect, and the two construction methods are compared and explained, so that the experiencer can understand the serious consequences of incorrect scaffolding construction and unreasonable support and collapsed support columns;

[0071] At the same time, the exhibit is equipped with a scaled-down scaffolding model, so that visitors can experience how to build a scaffolding by themselves and realize that correctly building a scaffolding is a basic requirement to ensure the safety of construction workers;

[0072] Among them, the construction elevator accident experience uses a real-life model of a construction elevator. Before entering the elevator, the experiencer will be reminded to check whether the elevator has landed smoothly and whether the elevator is tilted.

[0073] After entering the elevator, the experiencer checked whether the two doors were closed and whether the passengers were overweight;

[0074] At the same time, through personal experience of construction elevators, participants can better understand the common hidden dangers of construction elevators, the correct steps to take construction elevators, and effectively enhance their safety awareness of standardized construction;

[0075] Among them, the lifting hazard experience uses a simple model to build a mobile crane, and sets up light strips in dangerous areas such as under the crane hook and in the swing range of the boom. Combined with the principle of "ten no-lifting" in combination with lifting hazards, typical hidden danger points are set;

[0076] When the user touches a potential risk point or walks into a dangerous area, the sound and light alarm device will sound an alarm, and the large screen will display the principle of inducing the occurrence of such risk points and possible accidents.

[0077] At the same time, let the participants understand the basic safety production requirements of lifting operations, and strengthen the operating requirements such as "lifting operators must leave the moving range of the lifting objects";

[0078] Among them, the tower crane collapse accident experience constructs a tower crane scene atmosphere, and explains the precautions for preventing tower crane accidents through a large digital screen.

[0079] In this embodiment, the knowledge question bank sub-interface is entered, and the question bank knowledge content learning and random testing are carried out in this interface;

[0080] In this embodiment, the simulation drill sub-interface is entered, in which the user enters the three-dimensional twin simulation scene through the VR device combined with the somatosensory device; wherein,

[0081] By combining virtual reality with somatosensory equipment, an immersive training environment is created from the aspects of hearing and vision, and the safety hazards involved in working at heights are experienced. Functions such as interactive hazard investigation and escape skills simulation training are realized, which effectively improves the safety awareness of personnel working at heights, consolidates safety knowledge reserves, and masters emergency escape skills.

[0082] The simulation process triggers an accident simulation scene when the user makes an incorrect choice, and shows the accident consequences and wound surface in detail to enhance the learning effect and memory depth of the user.

[0083] In this embodiment, the experience user's selection settings affect the scene interaction effect and the data recording of the scoring system during the operation simulation;

[0084] During the simulation, the high-altitude operation is completed, or after an accident occurs, the drill ends and enters the scoring phase;

[0085] In the scoring phase, the system uses the scoring mechanism to experience the user's actual operation choices and actual interaction with the simulation scenario to score and evaluate the results, and reviews, analyzes, and corrects the overall operation process.

[0086] The maximum score for the operation score is 100 points. Set a score for each operation step. Set a score of 100 points for operation steps with major safety hazards, such as wearing a safety rope. For each wrong operation step, deduct the corresponding score. When the score is 0, the assessment ends and re-learning and assessment are arranged. Set a normal completion time for the entire process. The final operation score result is shown in the following formula Where T actual Represents the actual completion time, T expected Characterizes the set normal completion time, S operation Characterizing the operation step score, the formula satisfies the following conditions at the same time:

[0087] The function is a continuous function;

[0088] When the actual time spent is less than the stipulated time, the final score is the operation step score;

[0089] When the actual time spent is greater than the stipulated time, the final score decreases as the actual time spent increases;

[0090] When the actual time spent is greater than the prescribed time and approaches positive infinity, a maximum of 40 points will be deducted to ensure that students who operate completely correctly pass the assessment.

[0091] The final evaluation score is test paper score*0.5+operation score*0.5, with 60 points as a passing score.
