Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of simulation training, and in particular, to a military and police VR simulation training system and device. Background Art

[0002] With the development of technology, virtual reality (VR) technology has gradually been applied to various military and police trainings. Traditional training methods usually rely on live ammunition shooting, tactical scenario simulation, and physical training. Although these training methods have certain actual combat effects, there are also many problems and limitations. For example, live ammunition training is costly, requires a large training ground, is difficult to transport firearm simulators and real firearms, and has strict requirements for safety protection measures. In addition, traditional training methods are difficult to quickly switch or simulate complex and dangerous combat environments, making it difficult for training personnel to respond to emergencies or complex training scenarios.

[0003] In order to improve training efficiency and reduce costs, virtual reality technology has been introduced into the military and police training field. VR technology can simulate the visual, auditory, and operation feedback of a real battlefield in a virtual environment. Training personnel can complete trainings such as shooting, room storming, close quarters battle (CQB), and target reconnaissance under relatively safe conditions. However, most existing military and police VR simulation training systems are limited to basic shooting simulation and simple target training, lacking multi-dimensional simulation and feedback of complex combat environments. In addition, there are still significant deficiencies in the integration of hardware and software, the accuracy of training data, and the support for multi-person collaborative training in existing systems. It should also be noted that most of the existing military and police VR simulation training systems on the current market also have obvious deficiencies in terms of the portability of equipment, the scalability of virtual training scenarios, and the ability of real-time data transmission and feedback. Since military and police VR simulation training often needs to be carried out in the wild or temporary sites, it is difficult for existing systems to maintain stable network connections and data synchronization in complex terrains or areas far from base stations. In addition, the portability of equipment and the ability to support multiple scenarios have also become important factors affecting training effects.

[0004] Therefore, the key to solving the above problems is to propose a military and police VR simulation training system and device that can be used in various environments, has the characteristics of strong portability, realistic scene simulation, support for multi-person collaborative training, and can collect and analyze training data in real time.

[0042] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0043] The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments may be combined with each other.

[0044] The following detailed descriptions are all exemplary descriptions, aiming to provide further detailed descriptions of the present invention. Unless otherwise specified, all technical terms adopted by the present invention have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the present invention are only for describing specific implementation manners and are not intended to limit the exemplary embodiments according to the present invention.

[0045] Embodiment 1:

[0046] Please refer to Figure 1 As shown, the present invention provides a military and police VR simulation training system, which includes a coach terminal 10, a 5G transmission platform 20 and a training terminal 30. The coach terminal 10 includes a mode selection module 11, a combat environment simulation module 12, an AI-assisted training module 13, a coach observation module 14, a performance evaluation module 15 and a video playback module 16 connected in sequence. The 5G transmission platform 20 includes a 5G router. The training terminal 30 includes at least one set of training systems, and the training system includes a VR glasses 31, a position tracking device 32 and a military and police VR simulation training device 33.

[0047] The coach terminal 10 includes a mode selection module 11, a combat environment simulation module 12, an AI-assisted training module 13, a coach observation module 14, a performance evaluation module 15 and a video playback module 16 connected in sequence, and is used to manage and supervise the training process, simulate the combat environment, provide intelligent AI-assisted training, observe the performance of training personnel in real time, evaluate the training results, and playback the training video, so as to facilitate coaches and training personnel to analyze and summarize training experience; AsFigure 2 As shown in the figure, the coach terminal 10 further includes a portable computer 17, which is the carrier for the operation of the above modules and provides support for system simulation calculation and 3D rendering.

[0048] The mode selection module 11 is mainly used to flexibly select and configure different training modes according to training objectives and requirements, ensuring the pertinence and effectiveness of the training process.

[0049] Specifically, the mode selection module 11 provides a variety of training modes for users (i.e., coaches or training personnel) to choose from, including range training mode, mission execution mode, etc. Users can select a suitable mode according to specific training objectives and actual needs.

[0050] After selecting the training mode, users can configure relevant parameters through the interface, such as target type, training environment, time limit, task complexity, etc., to ensure the personalization and adaptability of the training content.

[0051] The mode selection module 11 runs specific training objectives set by users, such as improving shooting accuracy, increasing reaction speed, strengthening teamwork, etc., in order to monitor and evaluate the training effect during the training process.

[0052] Optionally, in the mission execution mode, the mode selection module 11 not only provides basic mission information, but also can guide users to complete specific training steps, such as target recognition, tactical selection, movement route planning, etc., improving the systematicness and effectiveness of the training.

[0053] The combat environment simulation module 12 uses 3D engine visualization technology to generate various virtual training scenarios (or called tactical scenarios), such as urban blocks, interior of buildings, etc., and then can simulate a variety of combat environments based on the virtual training scenarios. The design of these environments takes into account various factors such as terrain, building structure, lighting, weather, etc., ensuring the authenticity and diversity of the training. The combat environment simulation module 12 supports dynamic changes in the environment, such as weather changes, lighting changes (day and night alternation), and environmental sound effects (gunshots, explosions, environmental noises, etc.). This dynamic characteristic enhances the realism of the training, enabling training personnel to train under different environmental conditions. And the combat environment simulation module 12 can quickly adjust the scene position according to different training objectives, such as setting specific mission objectives, enemy positions, and movement paths, etc., so that training personnel can exercise tactical thinking and decision-making abilities in the simulated mission. The combat environment simulation module 12 can also simulate different types of targets, such as fixed targets, chest ring targets, and pop-up targets, to provide a shooting training environment.

[0054] The AI-assisted training module 13 utilizes advanced artificial intelligence algorithms to simulate the behavior patterns of enemy characters. These characters possess diverse combat styles and tactical strategies, enabling trainees to face different opponents and enhance their actual combat response capabilities. The AI-assisted training module 13 can adjust the behavior of enemy characters in real time according to the actions and strategies of trainees, making the confrontation training more realistic and challenging. The enemy characters will respond to the choices of trainees such as attacks, retreats, and tactics, forcing trainees to continuously adjust their tactics to cope with the changing battlefield situation. Specifically, the AI-assisted training module 13 can configure different enemy behavior patterns according to the set tactical scenarios, such as performing ambush, hostage-taking, or random patrol and other tactical actions. When dealing with these situations, trainees can not only improve their individual skills but also exercise their teamwork abilities. The module supports multiple training modes, including individual confrontation, teamwork, and complex tactical scenarios. Whether it is training for specific tactics or the improvement of comprehensive qualities, the AI-assisted training module 13 can flexibly adapt and provide a rich training experience.

[0055] The coach observation module 14 is used to display the training process so that coaches can monitor the training process in real time. Through the training guidance interface, they can view the dynamics of the training site, including the positions, behaviors, weapon usage of trainees, and the action responses of virtual enemies, and view the key event information and battle result and damage statistics information during the training process in real time. And it can adjust the quantity of weapons and ammunition and the health status of combatants in real time according to needs. The coach observation module 14 has a perspective switching function, including first-person perspective, third-person perspective, and global perspective, and can view the entire training process of trainees globally, such as details like walking paths, muzzle orientations, and cleared areas. The coach observation module 14 has a real-time event monitoring function, can dynamically view the key event information during the training process, control the key nodes, and can issue the status of trainees and statistically analyze information such as bullets, hits, friendly fire, and scores.

[0056] The performance evaluation module 15 is used to comprehensively evaluate the performance of trainees after the training according to the preset evaluation indicators. This module will automatically collect various data generated during the training, such as shooting accuracy, reaction time, task completion, safety awareness, etc., and compare them with the set standards. The performance evaluation module 15 not only calculates the comprehensive score of a single training but also can generate a detailed evaluation report (referred to as a report for short). In addition, the military and police VR simulation training system supports saving training data (including training instructions, action posture data of trainees, training videos, position and posture data of handheld devices, etc.) to the database. Coaches and trainees can view the historical records at any time, conduct performance comparison and analysis, and formulate subsequent training plans according to the data trends, enhancing the long-term tracking and evaluation ability of training effects.

[0057] In order to reduce the storage volume, the video playback module 16 can be used to record the key scenes of the entire training process in real time. This module can capture every action, decision and combat situation of the trainees in the virtual training environment (i.e., the simulated combat environment) and save it as a video file that can be traced back. After the training is completed, the coaches and trainees can review the entire training process through this module, analyze the effect of tactical execution from multiple perspectives, and find out potential tactical problems and shortcomings in response.

[0058] The video playback module 16 not only supports frame-by-frame playback and slow-motion analysis, but also can combine real-time combat damage and results data to help users understand the combat effect more clearly. For example, the health status, shooting hits, ammunition consumption and other data of the trainees during training will be displayed in real time on the playback screen. Through this function, coaches can quickly evaluate tactical effects, analyze combat losses of both sides, and combine data with actual operations to help trainees improve their tactical decision-making capabilities.

[0059] For example, Figure 2 As shown, the 5G transmission platform 20 (referred to as the platform) is the core communication bridge connecting the coaching terminal 10 and the training terminal 30, mainly including 5G routers 21 and other devices, which are used for high-speed, low-latency information transmission and data sharing between multiple training systems in the coaching terminal 10 and the training terminal 30. Through 5G technology, the platform can transmit a large amount of training data, tactical instructions, equipment status and sensor data in real time in a large-scale training environment.

[0060] The 5G transmission platform 20 ensures seamless communication between the coaching terminal 10 and the training terminal 30. During the training process, the coach can receive real-time operational information from the training terminal 30 through the platform, such as the behavior of the trainees, weapon operation, target strike effect, etc. At the same time, the coach can quickly convey information such as tactical adjustments and task instructions to the training terminal 30. The high bandwidth and low latency characteristics of 5G technology make these operations and feedback almost synchronous, ensuring that the coach can observe and adjust the training conditions in time during training.

[0061] In addition, the 5G transmission platform 20 also supports multi-user collaborative training. The behavior data, combat situation, and damage reports of multiple trainers can be transmitted to the coach terminal 10 in real time, helping coaches and systems to conduct effective training supervision and task analysis in complex mission environments. This efficient real-time communication capability provides technical support for improving the coordination, accuracy, and rapid response capabilities of training.

[0062] The training terminal 30 is a core component of the military and police VR simulation training system, responsible for providing immersive tactical training experiences for trainees. The training terminal 30 includes: a VR glasses 31, a position tracker 32, and a military and police VR simulation training device 33; which is used to provide a simulated combat environment for trainees and collect training instructions and the motion posture data of trainees.

[0063] The VR glasses 31 is the core interaction device in the military and police VR simulation training system. Optionally, the number of VR glasses 31 can be one or more (for example, 4), and the present embodiment does not make a specific limitation on the number of VR glasses 31. The VR glasses 31 integrates an action calibration module, a three-dimensional rendering module, and a data collection and feedback module, and can provide trainees with a highly immersive and real-time interactive virtual tactical training experience. The following is a detailed function description of each module:

[0064] Action calibration module: This module is used to accurately calibrate the three-dimensional space where the user (such as a trainee) is located when the VR glasses 31 are started. The calibration process includes scanning and positioning the boundaries, physical obstacles, etc. of the training site where the user is located, so as to ensure that all actions of the user in the virtual training are consistent with the actual environment. The action calibration module can accurately record the head rotation, limb movements, and spatial movements of trainees and synchronize them to the virtual training scene. This module not only ensures that every action of the user can be reflected in real time in the virtual battlefield, but also effectively prevents collisions or exceeding the safe area, improving the safety of training.

[0065] Three-dimensional rendering module: This module is responsible for generating a realistic virtual training scene and updating the display of the scene in real time according to the position, actions, and postures of the user. The three-dimensional rendering module can quickly generate complex combat scenes and simulate various tactical environments, such as urban street fighting, indoor CQB training, etc. The change of the user's perspective and body posture can be immediately reflected in the rendered scene, ensuring a high degree of consistency between the virtual world and the user's actual actions.

[0066] Data collection and feedback module: The core function of this module is to collect the data such as the actions and postures of trainees in real time and transmit this data to the coach terminal 10 for processing and analysis. Through the built-in sensors, the data collection module can accurately capture the tactical behaviors of the user's movement path, weapon aiming posture, shooting posture, etc., helping the coach understand the training performance of each trainee. All data will be immediately uploaded to the coach terminal 10 after being collected. The coach can monitor the training situation of trainees in real time and dynamically adjust the training content and difficulty according to the data results, further improving the training effect.

[0067] Through the mutual cooperation of the above modules, the VR glasses 31 can not only provide a highly immersive virtual combat environment, but also help training personnel respond more realistically to complex tactical environments through functions such as real-time data collection and feedback, and scene updating, comprehensively improving their tactical qualities and combat capabilities.

[0068] The position tracking device 32 is a key device in the military and police VR simulation training system, responsible for accurately positioning the position and attitude data of the handheld device in three-dimensional space, and then determining the real-time position and attitude of the training personnel to ensure a high degree of synchronization between the actions in the virtual training environment and the actual operations. This device includes a position sensor and a data sending module, which can collect and transmit the spatial position information and attitude angle data of the user in real time, improving the accuracy and immersion of the training.

[0069] Position sensor: The core of the position tracking device 32 is a high-precision position sensor, which can capture the position information and angular attitude of the user in three-dimensional space. Through the calibration of multiple reference points, the position sensor can accurately determine the three-dimensional space coordinates of the user in the training scene, ensuring that every action and movement can be reflected in the virtual environment without delay.

[0070] Data sending module: The position tracking device 32 is equipped with a high-speed data sending module, which is responsible for instantaneously transmitting the collected position and attitude data to the VR glasses 31 and the coach terminal 10 for processing and updating. The data sending module uses low-latency and high-bandwidth wireless communication technology to ensure that the position and attitude data can be transmitted to other parts of the system at the millisecond level. During the transmission process, the data sending module will continuously update the action postures and positions of the training personnel, and the VR glasses 31 will adjust the perspective and display content of the virtual training scene in real time according to these data, ensuring that every action of the user can be accurately reflected in the virtual world.

[0071] The military and police VR simulation training device 33 (or called pistol mounting device, firearm simulator, etc.) is an indispensable part of the present invention, aiming to enhance the realism and interactivity of the training. This device includes a handheld device, which integrates a variety of functional modules, including a position tracking device card slot, a firearm buckle, a micro sensor, a universal movement module, and a data transmission module, and can fully support the needs of virtual training.

[0072] Position tracking device card slot: This card slot is designed specifically for the position tracking device to ensure its stable installation and effective operation. The position tracking device is tightly combined with the handheld device through this card slot, and can collect the position and attitude data of the device in three-dimensional space in real time. This function enables the system to accurately capture every movement, turn, and attitude change when the user performs various training actions, so as to achieve real action feedback in the virtual training environment and enhance the immersion and interactive experience.

[0073] Gun buckle: The gun buckle equipped on the pistol mounting device is flexibly designed and can completely fix the pistol simulator or the real Type 92 pistol. The installation structure of this buckle ensures the stability and safety of the firearm during use, guaranteeing that the operations of the mounted firearm simulator can trigger corresponding micro sensors.

[0074] Micro sensor: The micro sensor is the core part of the pistol mounting device and can receive and identify various operation signals of the mounted pistol simulator or the real Type 92 pistol. These operations include firing, chambering, switching the safety, reloading the magazine, etc. Each operation will be accurately recorded by the sensor and converted into corresponding electronic signals. The high sensitivity and low latency characteristics of the micro sensor ensure the real-time capture of firearm operations, enhancing the interactivity and authenticity of the training.

[0075] Omnidirectional movement module: The omnidirectional movement module supports users to move freely in multiple directions, including forward, backward, left, and right. This multi-dimensional movement ability enables users to flexibly respond to various tactical requirements in virtual tactical scenarios, such as quickly evading, rapidly changing positions, and performing complex tactical actions. The module adopts advanced sensors and algorithms to ensure that users can maintain a high degree of stability and accuracy during movement. Whether moving quickly or making slow adjustments, the system can provide real-time feedback on the user's position and posture to ensure the accurate execution of actions.

[0076] Data transmission module: The data transmission module is responsible for instantaneously transmitting the firearm operation signals generated by the micro sensors to the VR glasses 31 and the instructor terminal 10. This module adopts advanced wireless communication technology to ensure the fast and stable transmission of data, avoiding a poor training experience caused by delays. Through seamless connection with the VR glasses 31 and the instructor terminal 10, every operation of the user can be immediately reflected in the virtual training scenario, and the instructor can also monitor the operations of the trainees in real time to provide timely feedback and guidance.

[0077] Overall design and function integration: The overall design of the pistol mounting device takes into account both portability and functionality. It is constructed with lightweight materials, facilitating the rapid deployment and use by users at the training site. The tight integration of each module enables the device to achieve efficient function output without adding additional burden. Its modular design also provides convenience for subsequent function expansion. For example, the position tracking accuracy can be upgraded or new sensor functions can be added according to requirements to adapt to different training scenarios and tactical needs.

[0078] In summary, the military and police VR simulation training device 33 provides a highly realistic and interactive training platform for trainees by integrating multiple functions such as position tracking, firearm simulation, and signal transmission. It not only improves the training effect but also provides strong support for enhancing the tactical literacy and reaction ability of military and police personnel.

[0079] Optionally, as Figure 3 shown, to support the above functional modules, the handheld device in the military and police VR simulation training device 33 may include the following circuits: a control unit (Micro Control Unit, MCU), a wireless data transmission module connected to the MCU through Transistor-Transistor Logic (TTL) or Input Output (IO) ports, a safety catch, a bolt, a trigger, and a magazine connected to the MCU through other IO ports, a program download port connected to the MCU through a Switch (SW) port, a joystick connected to the MCU through a 2-channel Analog-to-Digital Converter (ADC), a battery power detection circuit connected to the MCU through an ADC interface, and also includes a lithium battery, an anti-reverse connection circuit, a power-on and off circuit, a power-on and off button, and a Direct Current to Direct Current (DC-DC) power supply circuit, etc.

[0080] Among them, the other end of the battery power detection circuit is connected to the anti-reverse connection circuit, and the anti-reverse connection circuit is connected to the lithium battery, so it can be used to measure the battery voltage. After the power-on and off button is pressed, the power-on and off circuit can trigger the DC-DC power supply circuit to supply power to the MCU.
