Description

Technical Field

[0001] The invention belongs to the technical field of military simulation training, and in particular relates to a simulation grenade safety training system, method, equipment and storage medium. Background Art

[0002] A grenade is a small hand-thrown ammunition that can be used for both offense and defense. It is also the most widely used and consumed ammunition. Due to its small size, light weight and easy portability, hand grenades have played an important role in all modern wars.

[0003] At present, during the grenade throwing training, usually the throwing action is first trained with a silent simulated grenade, then with a lethal simulated grenade, and finally with a live ammunition throw. As the training effect of simulated grenades is not ideal, and most of the trainees are new recruits (new trainees) who have never thrown live ammunition, accidents often occur when throwing lethal simulated grenades and live ammunition, often causing casualties.

[0004] In the prior art, sensory stimulation can be generated for trainees by simulating explosion sounds, flashes, and smoke to improve the simulation of the results of simulated grenade throwing. However, trainees may develop fear during training for different reasons. Most trainees are novices who have no experience in actual combat and throwing, and they may subconsciously cover up wrong actions to avoid being discovered. From the statistical data, grenades are a relatively dangerous conventional weapon with the highest accident rate, death and injury rate. Trainees often have irregular avoidance actions due to fright and lack of experience. The fear of trainees will become a major obstacle in their training process, affecting their training effect. Their abnormal blood pressure and heart rate may even cause safety accidents.

[0005] Existing mental health testing methods mostly use questionnaires, oral questions and personal declarations, or only self-assess the psychological safety status of trainees. However, these methods are highly subjective, and the reliability and accuracy of judging the psychological state of trainees are low. In addition, the existing live-fire throwing supervision and safety measures are mostly aimed at handling after the accident. For example, the camera mainly records the throwing process and has no prediction function. The safety personnel are mainly responsible for handling and rescuing after the safety accident occurs. There is no way to know whether the accident may occur, and it is impossible to determine the key personnel who may cause the accident. The training method is still a one-to-many teaching model, and its main focus is more on demonstration and recording results. It is difficult to take into account the throwing process of the trainees and their psychological process, and it is impossible to record them. At the same time, the trainer cannot provide a training environment close to actual combat conditions. Summary of the invention

[0006] To this end, the present invention provides a simulated grenade safety training system, method, device and storage medium to solve the problem that the prior art is difficult to monitor the physical and mental health of trainees when using simulated grenades, resulting in poor training effects for trainees and potential safety hazards.

[0055] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] First, the terms involved in this application are explained:

[0057] Extended Reality (XR) refers to the combination of reality and virtuality through computers to create a virtual environment for human-computer interaction. It is also a general term for various technologies such as augmented reality (AR), virtual reality (VR), and mixed reality (MR). By integrating the visual interaction technologies of the three, it brings the experiencer an "immersive feeling" of seamless transition between the virtual world and the real world.

[0058] Virtual Reality (abbreviated as VR) is based on computer technology, utilizing and integrating the latest developments in three-dimensional graphics technology, multimedia technology, simulation technology, display technology, servo technology, and other high-tech technologies. With the help of computers and other equipment, it creates a virtual world with realistic three-dimensional vision, touch, smell, and other sensory experiences, giving people in the virtual world a sense of being immersed in the world.

[0059] Example 1

[0060] See also Figure 1 Embodiment 1 of the present invention provides a simulated grenade safety training system, comprising:

[0061] A simulated grenade 100, comprising a first detection unit, a second detection unit and a tracker; the first detection unit is used to detect the switching between the safety locking state and the safety releasing state of the simulated grenade; the second detection unit is used to detect the switching between the safety releasing state and the simulation excitation state of the simulated grenade; the tracker is used to locate the simulated grenade and obtain the position information of the simulated grenade;

[0062] The camera device 200 is used to capture and identify the body posture of the trainee and obtain the first body posture data of the trainee; it is also used to obtain the image of the trainee and identify whether the trainee performs a preset abnormal action, wherein the preset abnormal action includes shaking;

[0063] The wearable device 300 is used to generate sensory stimulation to the trainee according to the real-time image of the simulated grenade corresponding to the simulated grenade and the explosion picture of the simulated grenade, and collect the health indicators of the trainee;

[0064] Server 400 is used to construct a virtual reality scene, receive signals from the first detection unit, the second detection unit and the tracker, obtain the status and position information of the simulated grenade, and generate a real-time image of the simulated grenade in the virtual reality scene; it is also used to receive the position information of the simulated grenade, generate an explosion picture of the simulated grenade in the virtual reality scene, and generate training results in combination with the first body posture data of the trainee sent by the camera device and the preset abnormal action; it is also used to monitor and store the health indicators of the trainees in real time, determine whether the health indicators exceed the preset threshold, compare the health indicators with the historical health indicators, and establish a mapping relationship between the health indicators and the first body posture data, analyze the training process of the trainees according to the health indicators, and generate a training plan.

[0065] It should be noted that the "hand grenade" in the simulated hand grenade described in the present invention does not only refer to hand grenades, but also includes tear gas bombs, smoke bombs and other weapons that can also be thrown and can cause a certain striking effect.

[0066] It is understandable that the virtual reality scene described in the embodiment of the present application may include simulation and setting of multiple scenes, terrains or emergencies. For example, the virtual reality scene may include throwing on flat ground, throwing by obstacles, and may also include dangerous scenes with bomb shelters. At the same time, according to the data comparison before, during and after training, key personnel who may have a bad psychological state can be locked in advance; this technology is applied to the training of ordinary simulated grenades to collect relevant psychological state data; it can also be applied to live ammunition throwing to predict dangerous situations in advance. When it is found that the throwing personnel are too nervous, the hand shakes too violently, etc., the throwing can be stopped in advance to avoid accidents; when it is found that the throwing is too nervous and cannot be stopped, an alarm message can be issued to remind the protection personnel and the safety personnel to be vigilant and pay attention to possible accidents; after the throwing is completed, if it is found that the throwing personnel are too nervous, the hand shakes too violently, etc., the relevant personnel can be arranged to provide psychological counseling to the throwing personnel to avoid psychological stress reactions.

[0067] It is understandable that when trainees are in a psychological state such as tension or fear, especially for novices (new students), they are prone to forgetting movements, misremembering movements and trembling. Therefore, by identifying the captured images of trainees, it is also possible to determine whether the trainees have certain psychological abnormalities.

[0068] It is understandable that for the actual operation and application of the grenade, when the trainee uses the simulated grenade, there are different standard actions for each state of the simulated grenade. For example, when the simulated grenade is in the safety locked state, the trainee's operation on the simulated grenade includes holding and pulling the pin; when the simulated grenade is unlocked, the trainee's operation on the simulated grenade includes holding and throwing; when the simulated grenade is in the simulated excitation state, that is, after the trainee throws the simulated grenade, he should squat immediately. Therefore, according to these standard actions, the server 400 stores standard human body postures corresponding to each state of the simulated grenade, so that the first body posture data of the trainee can be compared and analyzed with the standard human body posture.

[0069] Specifically, the body joints of the trainee can be captured through a human posture detection algorithm; based on the skeletal lines between the body joints, the body posture of the trainee is generated, and then the first body posture data is matched with the target posture set to generate a posture matching result.

[0070] It is understandable that when the trainees are undergoing training, due to the multi-sensory stimulation generated by the wearable device 300, psychological fluctuations will occur in different action stages. For example, the trainees may not perform the pin pulling action properly due to concerns about the simulated grenade being detonated, or they may fail to squat in time after throwing the grenade due to fear of the explosion. As a result, the trainees' first body posture data does not conform to the standard human posture, and the training is hindered by psychological factors. The trainees' first body posture data is correlated with their health indicators. By monitoring the trainees' health indicators, the trainees can be guided in a targeted manner according to whether the health indicators exceed the threshold and the mapping relationship between the health indicators and the first body posture data, so as to achieve better training results.

[0071] In a possible implementation, the wearable device 300 may include a photoelectric heart rate / pulse wave sensor, a photoelectric blood oxygen saturation sensor, a photoelectric blood pressure sensor, and the like.

[0072] It should be noted that, considering that in virtual reality VR, the trainees cannot see their own hands and the entities of the simulated grenades in their hands, which is not conducive to operations such as pulling out pins, the wearable device 300 may also include a static detection module, which is used to detect the static posture of the trainees. When the trainees maintain a head-down posture for a preset time (for example, three seconds), the VR projection in front of the trainees is cancelled so that they can see the real object.

[0073] In a possible implementation, the health indicators include blood pressure, blood oxygen and heart rate, and determining whether the health indicators exceed preset thresholds includes: separately determining whether the blood pressure value exceeds a preset first threshold, whether the blood oxygen value exceeds a preset second threshold, and whether the heart rate exceeds a preset third threshold; if any of the health indicators exceeds its corresponding preset threshold, the health indicator is determined to exceed the preset threshold, and an alarm is sent by the server.

[0074] Specifically, the psychological fluctuations of the human body affect the secretion of hormones such as adrenaline, which causes changes in various human indicators, such as blood pressure, blood oxygen level and heart rate. When these indicators are significantly higher than the normal range, it indicates that the person may be over-stimulated or have a large psychological fluctuation due to fear and other reasons. Therefore, by testing these health indicators, it is possible to determine whether the trainee is in a normal training state.

[0075] Blood pressure refers to the lateral pressure exerted on the blood vessel wall per unit area when blood flows in the blood vessels, and is the driving force for blood to flow in the blood vessels. Usually, systolic blood pressure increases during exercise, while diastolic blood pressure sometimes increases and sometimes decreases. The degree of fluctuation depends on personal physique and the intensity of exercise or stimulation. Based on medical regulations, the first threshold can be systolic blood pressure between 90 and 140, and diastolic blood pressure between 60 and 90.

[0076] The blood oxygen value is used to mark the ratio of oxygenated hemoglobin to total hemoglobin in arterial blood. Generally speaking, when a person is exercising or frightened, the blood oxygen saturation value in the human body will decrease. The blood oxygen saturation of healthy people is generally above 94%, so the second threshold value can be 94 to 100.

[0077] Heart rate is divided into resting heart rate and exercise heart rate. Resting heart rate refers to the number of heartbeats per minute in a quiet state of wakefulness and inactivity. The normal resting heart rate is between 60-100 beats per minute. However, usually, the heart rate value will increase during exercise or psychological tension. The degree of increase is related to the degree of tension and the intensity of exercise. The third threshold can be set according to the physical function of the trainee. Based on medical advice, the third threshold can be 60 to (220-trainee age) × 0.8.

[0078] In one possible implementation, the training process of the trainee is analyzed according to the health indicator, including: based on the mapping relationship between the health indicator and the first body posture data, screening out the first body posture data whose health indicator exceeds a preset threshold as the target posture data, and counting the frequency of occurrence of the target posture data during the training of the trainee; and generating a list of the target posture data in order of frequency from most to least.

[0079] It is understandable that during training, trainees may experience greater psychological fluctuations at a certain stage of an action or for a certain action, which may be caused by lack of skill in the action or fear of accidents. For such actions, trainees will subconsciously hide their emotions and appear calm during training. If the action is standard and completed smoothly, trainees will not report that they have experienced psychological tension during the training of this action, and instructors cannot directly perceive the trainees' psychological process, but such actions are still risky actions.

[0080] Through the mapping relationship between the health index and the first body posture data, the action stage of the trainee when the trainee's psychology is obviously abnormal can be obtained, that is, the action represented by the first body posture data. During the entire training process, if the trainee frequently has abnormal health indicators when performing the action, it is obvious that the action is a key training action. Therefore, it can be used as the target posture data to strengthen the training later, and the instructor can also better guide and coach the trainee based on the correlation.

[0081] In a possible implementation, generating a training plan includes: dividing the training content of the trainee into different training actions based on the division of each first body posture data; setting the weight of the number of training times of the training actions corresponding to each target posture data according to the ratio of the frequency of each target posture data, and generating a training plan.

[0082] In this embodiment, the frequency of the target posture data can be analyzed, that is, the trainees' health indicators are most likely to be abnormal in which actions, so as to scientifically formulate a training plan based on the frequency of the target posture data. For example, if during a training session, the trainee has 3 abnormal heart rates when squatting after throwing and 2 abnormal heart rates when pulling the pin, then in the subsequent training plan, the squatting after throwing and the pulling the pin can be trained separately at a ratio of 3:2. The instructor can also explain these two actions in detail separately so that the trainees can better master them.

[0083] Furthermore, the instructor can also analyze the list of target posture data of multiple trainees, so as to explain and coach the movements that are most likely to cause abnormal health indicators of the trainees, which helps to improve the instructor's teaching effect.

[0084] Example 2

[0085] See also Figure 2 Embodiment 2 of the present invention provides a simulated grenade safety training method, which is applied to the simulated grenade safety training system of embodiment 1, and includes the following steps:

[0086] S201: Acquire real-time health indicators of the trainee, where the real-time health indicators include blood pressure, blood oxygen level and heart rate;

[0087] S202: storing the real-time health index according to time points, and determining whether the health index exceeds a preset threshold;

[0088] It is understandable that in each state stage of the simulated grenade, the trainee will make different movements, that is, the trainee will have different first body posture data. If the trainee's health index is abnormal and an alarm is issued, the instructor can stop the training and take emergency measures according to the situation. In addition, the alarm record includes the state of the simulated grenade corresponding to the abnormal health index, so that it can be preliminarily divided into which actions the trainee is prone to greater psychological fluctuations.

[0089] It should be noted that for trainees whose health indicators are abnormal during training, they must undergo training on handling dangerous situations in subsequent training because they are under great psychological pressure and have relatively weak tolerance. For trainees whose health indicators are not abnormal during training, instructors can selectively arrange for them to undergo training on handling dangerous situations based on actual conditions.

[0090] S203: If the health indicator exceeds a preset threshold, an alarm is issued and an alarm record is generated, wherein the alarm record includes a time point and a simulated grenade status at the corresponding time point;

[0091] S204: Generate a training plan for the trainee using the alarm record.

[0092] It is understandable that for actions that easily cause trainees to have greater psychological fluctuations, they can be divided according to the state of the simulated grenade, and the actions corresponding to the state of the simulated grenade can be trained in a targeted manner, so that the actions will be more coherent.

[0093] In this embodiment, by obtaining the real-time health indicators of the trainees, the health indicators include blood pressure value, blood oxygen value and heart rate, the real-time health indicators are stored according to time points, and it is determined whether the health indicators exceed the preset threshold value; an alarm is issued according to the health indicators and an alarm record is generated, the alarm record includes the time point and the status of the simulated grenade; a training plan for the trainees is generated based on the alarm record, which can, on the one hand, monitor the health of the trainees in real time with high timeliness and reliability; on the other hand, it can analyze the trainees' fear period and fatigue level, so as to formulate a personalized training plan for them.

[0094] In a possible implementation, before determining whether the health index exceeds a preset threshold, it also includes: obtaining the identity information of the trainee, and determining whether the health threshold data of the trainee is stored in a preset database based on the identity information of the trainee; if so, using the health threshold data as the preset threshold; if not, collecting the height and weight index of the trainee, and obtaining the trainee's athletic ability parameters based on the height and weight index, and using the product of the athletic ability parameters and the standard health threshold as the preset threshold.

[0095] It is understandable that each trainee has his or her own upper limit of physical fitness and different ranges of health indicators, and the health threshold data of the trainee can be obtained based on the trainee's regular physical examinations, etc. The health threshold data of the trainee can also be re-tested after a period of time.

[0096] If the trainee has not entered his / her health threshold data, such as during the first training, a simple assessment can also be made based on his / her body mass index (BMI). For example, when the trainee's BMI is lower than 18, his / her athletic ability parameter is set to 0.9, and when the trainee's BMI is between 18 and 20, his / her athletic ability parameter is set to 1.

[0097] In a possible implementation, the generation of a training plan for trainees based on alarm records includes: summarizing the number of times each simulated grenade state occurs according to the alarm records; splitting the training content of the trainees into different training actions according to the state of the simulated grenade, the training actions including safety lock training actions, safety release training actions and simulated excitation training actions; and setting the weight of the number of training times of the training actions corresponding to the abnormal state stage according to the ratio of the frequency of each abnormal state stage to generate a training plan.

[0098] It should be noted that the present invention provides a simulated grenade safety training method, which can monitor the health indicators of trainees without XR. That is to say, XR can solve the problems of venue and simulation feedback for the training process, but through the detection of blood pressure, blood oxygen and heart rate, it can also collect the health indicators of trainees before, during and after training in real time.

[0099] It is understandable that the instructor can have different analyses and response measures for the collection of health indicators of trainees before, during and after training. For example, for the health indicators of trainees before training, if the health indicators of trainees have been abnormal before training, it proves that the trainees are afraid of training. In this case, they should not be allowed to train, but intervention measures should be taken; for trainees with abnormal health indicators during training, analysis can be performed according to the above embodiments of this application; for trainees who still have abnormal health indicators after training, it can be judged that the trainees have weak psychological recovery ability, or that the stimulation is too strong, and certain intervention measures should also be taken.

[0100] It should be noted that the method of the embodiment of the present disclosure can be performed by a single device, such as a computer or a server. The method of the present embodiment can also be applied in a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of the embodiment of the present disclosure, and the multiple devices will interact with each other to complete the described method.

[0101] It should be noted that the above describes some embodiments of the present disclosure. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recorded in the claims can be performed in an order different from that in the above embodiments and still achieve the desired results. In addition, the processes depicted in the accompanying drawings do not necessarily require the specific order or continuous order shown to achieve the desired results. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.
