Description

Simulation grenade safety training system, method, equipment and storage medium

Technical Field

The invention belongs to the technical field of military simulation training, and particularly relates to a simulation grenade safety training system, a simulation grenade safety training method, simulation grenade safety training equipment and a storage medium.

Background

The grenade is a small hand-thrown ammunition capable of attacking and defending, is also an ammunition with wider use and larger consumption, and plays an important role in modern war in the past due to the characteristics of small volume, small mass and convenient carrying and use.

At present, in the mine throwing training process, the throwing action is usually trained by using a simulated mine without explosion, then the simulated mine with killing power is used for training, and finally the live ammunition throwing is carried out. Because the simulated grenade training effect is not ideal enough, and the training personnel are often new soldiers (new scholars) who never throw live ammunition, the simulated grenade with killing power and accidents occur during live ammunition throwing, and casualties are often caused.

In the prior art, sensory stimulation to trained personnel can be generated by simulating explosion sound, flash and smoke so as to improve the simulation degree of the simulated grenade throwing result, but the trained personnel can generate fear psychology due to different reasons in the training process, most trained personnel are novices without actual combat and actual throwing experience, and the phenomenon that false actions are hidden by subconscious masking is caused. From the data statistics, the grenade is a conventional weapon with higher risk, accident rate and death injury rate, the risk avoidance action of trained personnel is often irregular due to frightening and insufficient experience, the fear of the trained personnel becomes a big obstacle in the training process, the training effect is influenced, and even the abnormal blood pressure and heart rate of the trained personnel can cause safety accidents.

The existing psychological health detection methods mostly adopt the forms of questionnaires, oral questionnaires, personal declarations and the like, or only carry out self-evaluation on the psychological safety states of trained personnel, but the methods are high in subjectivity, low in reliability and low in accuracy in judgment on the psychological states of the trained personnel. In addition, the existing live-ball throwing supervision and safety measures are mainly aimed at the disposal after the accident, such as a camera is mainly used for recording the throwing process, the prejudging function is not provided, the safety personnel are mainly used for disposal and rescue after the safety accident, whether the accident is likely to happen is not known, and key personnel which are likely to happen accidents cannot be judged. The training method is still a one-to-many teaching and training mode, and the main energy is more in demonstration and record of the result, but the throwing process and the psychological process of the trainee are difficult to comprehensively consider and cannot be recorded, and meanwhile, the trainee cannot provide a training environment close to actual combat conditions.

Example 1

Referring to fig. 1, embodiment 1 of the present invention provides a simulated grenade security training system, comprising:

The simulation grenade 100 comprises a first detection unit, a second detection unit and a tracker, wherein the first detection unit is used for detecting the switching between the safe locking state and the arming state of the simulation grenade, the second detection unit is used for detecting the switching between the arming state and the simulation excitation state of the simulation grenade, and the tracker is used for positioning the simulation grenade and obtaining the position information of the simulation grenade;

The device comprises a camera device 200, a first image acquisition device and a second image acquisition device, wherein the camera device is used for shooting and identifying the body posture of a trained person and acquiring first body posture data of the trained person, and also used for acquiring images of the trained person and identifying whether the trained person executes preset abnormal actions, wherein the preset abnormal actions comprise tremble;

The wearing device 300 is used for generating sensory stimulus to trained personnel according to the real-time image of the simulated mine corresponding to the simulated mine and the explosion image of the simulated mine, and collecting health indexes of the trained personnel;

The server 400 is configured to construct a virtual reality scene, receive signals of the first detection unit, the second detection unit and the tracker, acquire state and position information of the simulated grenade, generate a real-time image of the simulated grenade in the virtual reality scene, receive position information of the simulated grenade, generate an explosion picture of the simulated grenade in the virtual reality scene, generate a training result by combining first body posture data of a trained person and preset abnormal actions sent by the camera device, monitor and store health indexes of the trained person in real time, judge whether the health indexes exceed a preset threshold value, compare the health indexes with historical health indexes, establish a mapping relation between the health indexes and the first body posture data, analyze a training process of the trained person according to the health indexes, and generate a training plan.

It should be noted that, the "grenade" in the simulated grenade in the invention not only refers to grenade, but also includes weapon that can be thrown by tear-gas shells, smoke shells and the like, and can cause a certain striking effect.

It may be understood that the virtual reality scenario described in the embodiments of the present application may include simulation and setting of various scenarios, terrains or emergency situations, and by way of example, the virtual reality scenario may include land throwing, obstacle throwing, or dangerous situations where a bullet avoidance trench is provided. The method can be used for locking key personnel with possibly bad psychological states in advance according to data comparison before, during and after training, is applied to training of common simulated grenades for collecting relevant psychological state data, can be also applied to live-action throwing for conducting dangerous situation pre-judgment in advance, can stop throwing in advance when the situation that the throwing personnel is too intense in psychological state, hand shake is too intense and the like is found, avoids accidents, can send alarm information when the situation that the throwing personnel is too intense and cannot stop is found, reminds protection personnel and safety personnel to improve vigilance, and notices possible accidents, and can arrange relevant personnel to conduct psychological coaching on the throwing personnel when the situation that the throwing personnel is too intense in psychological state, the hand shake is too intense and the like is found after the throwing is finished, so that psychological stress reaction is avoided.

It can be understood that when the trained personnel has mental states such as tension and fear, especially for novice (new student), the situation of forgetting actions, mistaking actions and trembling easily occurs, so that whether the trained personnel has certain mental abnormality factors can be judged by identifying the photographed images of the trained personnel.

It will be appreciated that for practical operation and use of the mine, the trainee has different standard actions for each state of the simulated mine when using the simulated mine. For example, the operation of the trained personnel on the simulated mine comprises holding and pulling pins when the simulated mine is in a safe locking state, the operation of the trained personnel on the simulated mine comprises holding and throwing when the simulated mine is in an unlocking state, and the trained personnel should squat down immediately when the simulated mine is in a simulated excitation state, namely after throwing the simulated mine. Therefore, according to these standard actions, the server 400 stores therein standard human body attitudes corresponding to the respective states of the simulated grenade, so that the first human body attitudes data of the trained person can be compared and analyzed with the standard human body attitudes.

The method comprises the steps of capturing body joint points of trained personnel through a human body posture detection algorithm, generating the body posture of the trained personnel based on skeleton connection lines among the body joint points, and then matching first body posture data with the target posture set to generate a posture matching result.

It can be understood that, when the trained person performs training, due to the multi-sensory stimulation generated by the wearable device 300, psychological fluctuation may occur in different action stages, for example, the pin pulling action may be irregular due to worry that the simulated grenade is detonated, or after throwing out, the first body posture data of the trained person does not conform to the standard body posture due to the fear of explosion, and training caused by psychological factors is blocked, the first body posture data of the trained person and the health index thereof show correlation, and the trained person can be guided in a targeted manner according to whether the health index exceeds the threshold value and the mapping relation between the health index and the first body posture data by monitoring the health index of the trained person, thereby achieving better training effect.

In one possible embodiment, the wearable device 300 may include an optoelectronic heart rate/pulse wave sensor, an optoelectronic blood oxygen saturation sensor, an optoelectronic blood pressure sensor, etc.

It should be noted that, considering that in the virtual reality VR, the trainee cannot see the hand and the entity of the simulated grenade held by the hand, which is not beneficial to the operations such as pulling the pin, the wearable device 300 may further include a static detection module, where the static detection module is configured to detect the static posture of the trainee, and when the trainee keeps the low-head posture for a preset time (for example, three seconds), the projection of the VR in front of the eyes of the trainee is cancelled, so that the trainee can see the entity.

In one possible implementation manner, the health index comprises a blood pressure value, an oxygen blood value and a heart rate, and judging whether the health index exceeds a preset threshold value or not comprises respectively judging whether the blood pressure value exceeds a preset first threshold value, whether the oxygen blood value exceeds a preset second threshold value and whether the heart rate exceeds a preset third threshold value or not, and if any health index exceeds the corresponding preset threshold value, judging that the health index exceeds the preset threshold value and sending an alarm by a server.

Specifically, due to psychological fluctuations of the human body, secretion of hormones such as epinephrine is affected, thereby causing changes in various indexes of the human body such as blood pressure value, blood oxygen value and heart rate. When these indicators are significantly higher than normal, this indicates that the person may be overstimulated or may have a large psychological fluctuation due to fear or the like. Thus, by detecting these health indicators, it can be determined whether the trained person is in a normal training state.

The blood pressure is a lateral pressure acting on a wall of a blood vessel per unit area when blood flows in the blood vessel, and is a motive force for pushing the blood to flow in the blood vessel. In general, systolic blood pressure increases during exercise, while diastolic blood pressure increases and decreases at times, the extent of fluctuation depending on the constitution of the individual and the severity of the exercise or stimulus. Based on medical regulations, the first threshold may be a systolic pressure between 90 and 140 and a diastolic pressure between 60 and 90.

Blood oxygen values are used to mark the ratio of oxygenated hemoglobin to total hemoglobin in arterial blood. Typically, when a person is in motion or is frightened, the blood oxygen saturation level in the person will be reduced, and the blood oxygen saturation level in healthy people is generally 94% or more, so the second threshold may be 94 to 100.

Heart rate is divided into resting heart rate and exercise heart rate, resting heart rate means the number of beats per minute in a calm state of wakefulness and inactivity, and normal resting heart rate is between 60 and 100 beats per minute, but in general, the heart rate value will rise during exercise or mental stress, and the rise degree is related to the stress degree and the exercise intensity degree. The third threshold may be set according to the physical function of the trainee, and based on the medical advice, the third threshold may be 60 to (220-age of trainee) ×0.8.

In a possible implementation manner, the analysis of the training process of the trained personnel according to the health index comprises the steps of screening out first body posture data, exceeding a preset threshold, of the health index based on the mapping relation between the health index and the first body posture data as target posture data, counting the occurrence frequency of the target posture data of the trained personnel in the training process, and generating a list of the target posture data according to the sequence of at least more frequency.

It will be appreciated that the trainee may be in training at a certain stage of the action, or may have a large psychological fluctuation for a certain action, possibly due to unskilled action/fear of accidents. For such actions, the trainee can subconsciously hide the emotion of the trainee, and the trainee can be calm, if the action standard is finished smoothly, the trainee can not feed back the psychological tension condition in the training of the action, and the instructor can not directly perceive the psychological process of the trainee, but the action is still a risky action.

Through the mapping relation between the health index and the first body posture data, the action stage of the trained personnel, namely the action represented by the first body posture data, can be obtained when obvious abnormal psychology occurs to the trained personnel. In the whole training process, if the trained personnel frequently generates abnormal conditions of health indexes when doing the action, the action is obviously a key training action, so that the action can be used as target posture data, the training is enhanced later, and the instructor can better guide and coach the trained personnel according to the correlation.

In one possible implementation mode, the training program generation method comprises the steps of dividing training content of trained personnel into different training actions based on division of all first body posture data, and setting weights of training times of training actions corresponding to all target posture data according to frequency proportion of all target posture data to generate the training program.

In this embodiment, the frequency of the target gesture data may be analyzed, that is, it is analyzed in which actions of the trained personnel are most likely to have abnormal health indexes, so that a training plan is scientifically formulated according to the frequency of the target gesture data. For example, if during one training process, the trained personnel has 3 heart rate anomalies when throwing the squatting motion, and has 2 heart rate anomalies when pulling out the pin, then during the subsequent training program, the squatting motion and the pin pulling motion can be independently trained according to the ratio of 3:2. The instructor can also individually teach these two actions in detail so that the trainee can better understand them.

Furthermore, the instructor can analyze the lists of the target posture data of a plurality of trained personnel, so that the action which is most likely to cause the abnormal health indexes of the trained personnel is specifically taught and coached, and the teaching effect of the instructor is improved.

Example 2

Referring to fig. 2, embodiment 2 of the present invention provides a simulated grenade security training method, which is applied to the simulated grenade security training system of embodiment 1, and includes the following steps:

S201, acquiring real-time health indexes of trained personnel, wherein the real-time health indexes comprise blood pressure values, blood oxygen values and heart rates;

s202, storing the real-time health index according to a time point, and judging whether the health index exceeds a preset threshold value or not;

It will be appreciated that during the state phase of each simulated grenade, the trainee will take different actions, that is, the trainee will have different first body position data. If the health index of the trained personnel is abnormal, an alarm is given, and the instructor can stop training according to the situation to carry out emergency treatment. In addition, the alarm record comprises the state of the simulated grenade corresponding to the abnormal health index, so that the situation that the trained personnel do which actions easily occur large psychological fluctuation can be primarily divided.

It should be noted that, for the trained personnel with abnormal health indexes in the training, the training process has relatively weak bearing capacity due to relatively high physical stress, so that the training of dangerous situations in the subsequent training is necessary. For trained personnel without abnormal health indexes in training, the instructor can selectively arrange the trainees to carry out dangerous case treatment training according to actual conditions.

S203, if the health index exceeds a preset threshold, sending out an alarm and generating an alarm record, wherein the alarm record comprises a time point and a simulation grenade state corresponding to the time point;

s204, generating a training plan of the trained personnel by utilizing the alarm record.

It can be understood that for the actions which make the trained personnel easily generate larger psychological fluctuation, the actions corresponding to the states of the simulated grenade can be trained in a targeted manner according to the states of the simulated grenade, so that the actions are more coherent.

In the embodiment, the real-time health index of the trained personnel is obtained, the health index comprises a blood pressure value, a blood oxygen value and a heart rate, the real-time health index is stored according to time points, whether the health index exceeds a preset threshold value or not is judged, an alarm is sent out according to the health index, an alarm record is generated, the alarm record comprises the time points and the state of the simulated grenade, a training plan of the trained personnel is generated based on the alarm record, on one hand, the health of the trained personnel can be monitored in real time, the timeliness is high, the reliability is high, on the other hand, the fear period and the fatigue degree of the trained personnel can be analyzed, and therefore the personalized training plan of the trained personnel can be formulated.

In a possible implementation manner, before judging whether the health index exceeds the preset threshold, the method further comprises the steps of obtaining identity information of a trained person, judging whether health threshold data of the trained person are stored in a preset database based on the identity information of the trained person, if yes, taking the health threshold data as the preset threshold, otherwise, collecting a body height and body weight index of the trained person, obtaining exercise capacity parameters of the trained person based on the body height and body weight index, and taking the product of the exercise capacity parameters and a standard health threshold as the preset threshold.

It can be understood that, for each trained person, the human body has respective upper physical limit and different health index ranges, and the health threshold data can be obtained according to the items such as physical detection of the trained person at ordinary times. The health threshold data of the trained personnel can also be re-detected after a period of time.

If the trained person does not enter his health threshold data, such as the first training, a simple evaluation may be made based on his Body Mass Index (BMI), and, for example, the exercise capacity parameter is set to 0.9 when the trained person's BMI is below 18, and to 1 when the trained person's BMI is in the range of 18 to 20.

In a possible implementation manner, the method for generating the training plan of the trained personnel based on the alarm records comprises the steps of summarizing the times of the states of each simulated grenade in the alarm records, splitting the training content of the trained personnel into different training actions according to the states of the simulated grenade, wherein the training actions comprise a safe locking training action, a disarming training action and a simulated excitation training action, setting the weight of the training times of the training actions corresponding to the abnormal state phases according to the proportion of the frequency of each abnormal state phase, and generating the training plan.

It should be noted that, the simulation grenade safety training method provided by the invention can monitor the health index of the trained personnel under the condition of no XR, that is, the XR can solve the problems of the site and the simulation feedback for the training process, but the health index before, during and after the training of the trained personnel can be acquired in real time through the detection of the blood pressure value, the blood oxygen value and the heart rate.

It will be appreciated that the instructor may have different analyses and countermeasures for the health index acquisition before, during and after training by the trainee. For example, for the health index before training the trained personnel, if the health index is abnormal before training the trained personnel, the trained personnel is proved to have fear of being trained, and intervention measures should be performed instead of being trained under the condition, for the health index abnormality during training the trained personnel, analysis can be performed according to the embodiment of the application, and for the health index abnormality still occurring after training the trained personnel, the mental recovery capability of the trained personnel can be judged to be weak, or the stimulus received by the trained personnel is too strong, and certain intervention measures should be adopted.

It should be noted that the method of the embodiments of the present disclosure may be performed by a single device, such as a computer or a server. The method of the embodiment can also be applied to a distributed scene, and is completed by mutually matching a plurality of devices. In the case of such a distributed scenario, one of the devices may perform only one or more steps of the methods of embodiments of the present disclosure, the devices interacting with each other to accomplish the methods.

It should be noted that the foregoing describes some embodiments of the present disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments described above and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results.
