Description

Technical Field

[0001] This invention relates to the field of flight simulation technology, specifically to a dynamic flight simulator for astronaut training. Background Technology

[0002] Astronauts undergo various training programs before space missions to adapt to and cope with the unique space environment and mission requirements. Among these, training in areas such as balance and adjustment, psychological regulation and breathing control, reaction speed and concentration, and spatial awareness is crucial. To improve training effectiveness, innovative astronaut training equipment is needed.

[0003] Currently, there are some astronaut training devices, such as weightlessness flight simulators and virtual reality training systems. However, these devices have some limitations. They usually train astronauts by pre-setting fixed training modes and cannot adjust the training intensity according to the training data and physical skills of different astronauts. Therefore, a dynamic flight simulator for astronaut training is designed.

[0004] To address the aforementioned shortcomings, a technical solution is provided. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that existing astronaut training equipment usually trains astronauts by pre-setting fixed training modes, and cannot adjust the training intensity according to the training data and physical skills of different astronauts. Therefore, this invention proposes a dynamic flight simulator for astronaut training.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A dynamic flight simulator for astronaut training includes:

[0008] The simulation module is used for flight simulation training of astronauts;

[0009] The evaluation module is used to record the astronauts' data cooperation during training and to evaluate the astronauts' test data and overall qualities.

[0010] The specific astronaut training and testing data acquired include: position and attitude data, heart rate and respiration data, reaction time and attention data, and spatial orientation and navigation data. These data are analyzed to calculate attitude, response, intention, and orientation values. After normalization, these values ​​are then substituted into the following formula: The total score ZPZ is obtained by formulating the pose value, adjustment value, intention value and orientation value, respectively. These are the preset weighting coefficients for pose value, adjustment value, desired value, and orientation, respectively;

[0011] The calculated total score ZPZ is then compared with several preset total score intervals. Each of these intervals corresponds to a simulation difficulty adjustment standard. Once the total score interval to which the astronaut's total score ZPZ belongs is determined, the corresponding simulation difficulty adjustment standard for that astronaut is obtained and sent to the adjustment module.

[0012] The adjustment module is used to receive the simulation difficulty adjustment standard transmitted by the evaluation module and adjust the intensity of the simulation module accordingly.

[0013] The different difficulty adjustment standards correspond to different training intensities. The specific adjustment items include: flight mission complexity, environmental simulation, instrument and control system and time settings, and the above items are divided into levels corresponding to several difficulty adjustment standards.

[0014] The training suggestion module is used to provide training suggestions for astronauts' shortcomings based on the analysis of their comprehensive qualities.

[0015] Furthermore, the adjustment module specifically includes adjusting the flight mission complexity, environmental simulation, instrument and control system settings, and time settings, including:

[0016] Flight mission complexity includes the mission's difficulty level, diversity level, and urgency level;

[0017] Environmental simulation can increase or decrease the astronaut's perception in the flight simulator by adjusting environmental simulation parameters in the flight simulator, including visual effect level, sound level, and gravity simulation level.

[0018] The instrument and control system settings in the flight simulator are adjusted by increasing or decreasing the number and complexity of instruments according to different difficulty levels, and adding or removing complex control systems and fault simulations.

[0019] The time setting allows you to set time limits for flight simulator tasks, with different time limits set according to different training intensities.

[0020] The specific adjustment items are sent to the simulation module according to the corresponding difficulty adjustment standards to adjust the intensity of the flight simulation, so as to adapt to the standard of the astronaut's comprehensive quality.

[0021] Furthermore, the specific steps for the training suggestion module to provide training suggestions for the astronauts' weaknesses based on the comprehensive quality analysis are as follows:

[0022] First, obtain the specific data of the parameters for calculating the astronaut's overall evaluation, including: attitude value, response value, intention value, and orientation value. Compare these parameters with their corresponding preset parameter ranges. If any parameter falls outside the specified range, provide the astronaut with a corresponding prompt. Specifically:

[0023] When the posture value is outside the preset parameter range, the astronaut will be prompted to conduct targeted body balance and adjustment training; specifically including microgravity adaptation training and balance training.

[0024] When the adjustment value is outside the preset parameter range, the astronaut will be prompted with targeted psychological adjustment and breathing control training; specifically including meditation and relaxation training and breathing control training.

[0025] When the response value is outside the preset parameter range, the astronaut will be prompted: targeted training will be conducted on the astronaut's reaction speed and concentration ability, specifically including reaction speed training and attention training;

[0026] When the position value is outside the preset parameter range, the astronaut will be prompted: targeted training will be conducted on the astronaut's spatial perception, specifically including three-dimensional space training and visual training.

[0027] Furthermore, the simulation module consists of a motion seat, a virtual reality display device, and a control unit;

[0028] The motion seat consists of an adjustable seat and a support structure. The adjustable seat is used to move in multiple axes to simulate acceleration and attitude changes during flight. The support structure is used to ensure the safety and stability of the astronaut when moving in the adjustable seat.

[0029] The virtual reality display device includes a head-mounted display and headphones, used to provide virtual reality scenes and sound effects, simulate a space environment through the head-mounted display, and hear corresponding sounds through the headphones, including engine noise and communication sounds;

[0030] The control unit is used to control the movement of the simulation module and the generation of virtual reality scenes. According to the preset tasks and training plans, the control unit simulates different flight scenarios and adjusts the movement mode of the seat.

[0031] Furthermore, the specific steps for the evaluation module to analyze the position and attitude data to obtain the pose value are as follows:

[0032] First, the position and posture changes of the astronauts during the training process are recorded. Specifically, the position change speed, hand posture change amplitude, leg posture change amplitude, and head change amplitude are obtained during the astronauts' training. The real-time position change speed is compared with several preset position change speed intervals to determine the interval to which the real-time position change speed belongs. Each of the several position change speed intervals corresponds to a different position and posture standard value.

[0033] Next, outliers exceeding the standard range for hand, leg, and head posture changes during astronaut training are removed. Then, the average values ​​for each of these values ​​are calculated and denoted as SH, TH, and TB, respectively. After normalization, these values ​​are entered into the following formula: To obtain the pose value WZZ, in the formula These are preset weighting coefficients for the average amplitude of hand posture changes, the average amplitude of leg posture changes, and the average amplitude of head posture changes.

[0034] Furthermore, the specific steps for the evaluation module to analyze heart rate and respiratory data to obtain the adjustment value are as follows:

[0035] First, acquire the astronauts' heart rate and breathing data during training, specifically including: heart rate variability, respiratory rate and depth, and changes in heart rate and breathing.

[0036] Heart rate variability refers to the variation in the interval between heartbeats of an astronaut; respiratory rate and depth reflect the stress response and regulation of the astronaut's respiratory system; and the obtained heart rate and respiratory variation data are used to establish heart rate and respiratory variation curves.

[0037] The standard deviation of heart rate variability is calculated by measuring the heart rate variability of astronauts. Then, the standard deviation of respiratory rate and the average respiratory volume of astronauts are obtained by measuring respiratory rate and depth, respectively. Then, two sets of constant lines are established in the established heart rate and respiratory change curves by using preset upper and lower intervals of heart rate and respiratory rate. The area of ​​the heart rate and respiratory curves that exceeds the two sets of constant lines is calculated. The excess heart area and excess respiratory area are obtained and summed to obtain the excess range value.

[0038] After normalizing the obtained standard deviation of heart rate variability, standard deviation of respiratory rate, mean respiratory volume, and out-of-range value, the mean respiratory volume is summed with the standard deviation of variability and the standard deviation of respiratory rate and used as the radius to establish a base circle. The sum of respiratory volume and out-of-range value is used as the height to establish a cylinder. The center of the base circle is used as the center of the cutting base circle, and the sum of the standard deviation of heart rate variability and the standard deviation of respiratory rate is used as the diameter to establish a cutting base circle. The out-of-range value is used as the height and in the same direction as the cylinder to establish a cone. The difference between the volume of the cylinder and the volume of the cone is calculated and calibrated as the adjustment value.

[0039] Furthermore, the specific steps for the evaluation module to analyze reaction time and attention data to obtain the response value are as follows:

[0040] First, the astronauts' reaction time and attention were tested. The specific steps for the reaction time test are as follows: Using a computer or special equipment, visual or auditory stimuli were presented, and the astronauts were asked to make corresponding action responses as soon as possible, including pressing a button or other operations. The time difference between the stimulus presentation and the response action was recorded to obtain the astronaut's reaction time. The average of the time differences obtained from the stimulus presentation under different situations was calculated to obtain the reaction value.

[0041] The specific steps for the attention test are as follows: different cognitive tasks are used to assess the astronauts' attention level, including the line-connecting test, the number search test, and the Stroop test; among them, the line-connecting test requires the astronauts to connect matching items or graphics by drawing lines within a certain time, which assesses the astronauts' hand-eye coordination and attention transfer ability, and obtains the time required for the astronauts to complete the task and marks it as the completion value;

[0042] The number search test assesses an astronaut's selective attention and rapid orientation attention by finding a specific target number within a given time. The number of numbers found is used as the evaluation metric. The Stroop test assesses an astronaut's inhibitory control and reaction inhibition abilities by identifying colors among a series of presented texts where the texts do not match their colors. The Stroop test measures the time or accuracy required for the astronaut to complete the task and calculates a Stroop effect index to measure the degree of interference when identifying colors that do not match text. The time required for the astronaut to complete the task is calculated based on different preset Stroop effect indices, and the average is taken to obtain the effectiveness value.

[0043] The obtained reaction value, completion value, specific value, and effective completion value are then labeled as fy, ws, ts, and xw, respectively, and after normalization, they are substituted into the following formula: To obtain the desired value YYZ, in the formula These are preset weighting coefficients for reaction value, completion value, special value, and effective completion value, respectively.

[0044] Furthermore, the specific steps for the evaluation module to analyze spatial orientation and navigation data to obtain the positional value are as follows:

[0045] First, during the training process, the astronauts' positioning and sense of direction in three-dimensional space are tested. The specific testing steps are as follows: The spatial awareness test involves prompting the astronauts to look around and close their eyes. The astronauts' position and direction are then slowly and randomly changed. After the adjustment is completed, the astronauts' voice reports of the position and direction are analyzed to determine whether the position and direction reported by the astronauts are correct. Several tests are conducted to obtain the astronauts' judgment accuracy rate. This accuracy rate is used to measure the astronauts' spatial awareness ability.

[0046] The coordinate system transformation capability test involves displaying one coordinate system and prompting the astronauts to transform to another coordinate system standard. The input results of the astronauts are collected to obtain the transformation error rate and usage time of a single test. After normalization, the transformation error rate is multiplied by the usage time to obtain the time error value. Multiple tests are conducted to obtain multiple time error values. The average time error value is obtained by averaging the multiple time error values. This average time error value is used as the standard to measure the astronaut's coordinate system transformation capability.

[0047] Space memory training uses display devices to simulate various equipment, instruments, and buttons used to control flight inside a spacecraft. Different equipment, instruments, and buttons are first labeled with their specific names, functions, usage methods, and locations. Astronauts observe these devices for a preset time, then the labels are removed. Equipment, instruments, and buttons are randomly selected, and the labels entered by the astronauts are obtained. The error rate of the astronauts' input is analyzed. This process is repeated multiple times to obtain several error rates. The average error rate is then calculated from these error rates.

[0048] The control and coordination test involves setting up a standard difficulty flight route and simulating flight scenarios. Astronauts perform simulated flight by operating the routes, including propulsion, rotation, deceleration, and turning. After the simulated flight is completed, the degree of overlap between the astronauts' simulated flight route and the preset flight route is analyzed.

[0049] The obtained accuracy, mean timeout, mean error rate, and overlap are then labeled as qe, wj, lj, and ch, respectively, and normalized before being substituted into the following formula: The positional value WFZ is obtained.

[0050] Compared with the prior art, the beneficial effects of the present invention are:

[0051] This invention records data on astronauts during training, evaluates their test data and overall qualities, and adjusts the intensity of training accordingly based on the analysis of their overall qualities to suit different astronauts, thereby improving the training effectiveness of trainers.

[0058] like Figure 1 As shown, a dynamic flight simulator for astronaut training includes a simulation module, an evaluation module, an adjustment module, and a training prompt module;

[0059] The simulation module is used for flight simulation training of astronauts;

[0060] The motion seat consists of an adjustable seat and a support structure. The adjustable seat is used to move in multiple axes to simulate acceleration and attitude changes during flight; the support structure is used to ensure the safety and stability of astronauts when moving in the adjustable seat.

[0061] Virtual reality display devices, including head-mounted displays and headphones, are used to provide virtual reality scenes and sound effects, simulating a space environment through the head-mounted display and hearing corresponding sounds through the headphones, including engine noise and communication sounds;

[0062] The control unit is used to control the movement of the simulation module and the generation of virtual reality scenes. According to the preset tasks and training plans, the control unit simulates different flight scenarios and adjusts the movement of the seat to achieve a more realistic training effect.

[0063] The evaluation module is used to record astronauts' data cooperation during training and to evaluate their test data and overall qualities. The specific astronaut training and test data acquired includes:

[0064] Position and attitude data: Record the astronaut's position and attitude changes during training, specifically acquiring the velocity of position change, amplitude of hand posture changes, amplitude of leg posture changes, and amplitude of head posture changes. The obtained real-time position change velocity is compared with several preset position change velocity intervals to determine the interval to which the real-time position change velocity belongs. These intervals correspond to different standard values ​​for position and attitude. Then, outliers exceeding the standard amplitude ranges for hand, leg, and head posture changes are removed. The average values ​​for each amplitude are then calculated and labeled as SH, TH, and TB, respectively. After normalization, these values ​​are entered into the following formula: To obtain the pose value WZZ, in the formula The preset weighting coefficients for the average amplitude of hand posture changes, the average amplitude of leg posture changes, and the average amplitude of head posture changes are respectively set by those skilled in the art, and can be 0.856, 1.115, and 1.026.

[0065] Heart rate and respiratory data: Acquire astronauts' heart rate and respiratory data during training, specifically including: heart rate variability, respiratory rate and depth, and changes in heart rate and respiration; heart rate variability is the change in the interval between heartbeats of the astronauts. Higher heart rate variability is generally considered an indicator of health and adaptability, indicating that the body has a better ability to regulate stress; respiratory rate and depth reflect the stress response and regulation of the astronauts' respiratory system. Under normal circumstances, respiratory rate and depth will increase during stress to provide more oxygen and regulate the body's metabolic needs; and establish heart rate and respiratory change curves based on the obtained heart rate and respiratory change data.

[0066] The standard deviation of heart rate variability was calculated by analyzing the astronauts' heart rate variability. Then, the standard deviation of respiratory rate and the average respiratory volume were obtained using respiratory rate and depth, respectively. Next, two sets of constant lines were established from the heart rate and respiratory change curves using preset upper and lower intervals for heart rate and respiratory rate. The areas exceeding these constant lines were then calculated, and the resulting areas of excess heart rate and excess respiratory rate were summed to obtain the excess range value. Finally, the standard deviation of heart rate variability, standard deviation of respiratory rate, average respiratory volume, and excess range value were normalized. Finally, the average respiratory volume was compared with the standard deviation of heart rate variability. The standard deviations of heart rate variability and respiratory rate are summed and used as the radius to establish a base circle. The sum of respiratory volume and the out-of-range value is used as the height to establish a cylinder. The center of the base circle is used as the center of the cleaving base circle. The sum of the standard deviations of heart rate variability and respiratory rate is used as the diameter to establish a cleaving base circle. A cone is established with the out-of-range value as the height and in the same direction as the cylinder. The difference between the volume of the cylinder and the volume of the cone is calculated and calibrated as the stress value. The stress value is used to measure the astronaut's emergency response and regulation ability. The larger the stress value, the higher the astronaut's emergency response and regulation ability in the simulated scenario.

[0067] Reaction time and attention data: Astronauts' reaction time and attention were tested. The specific steps for the reaction time test were as follows: Using a computer or specialized equipment, visual or auditory stimuli were presented, and astronauts were required to make corresponding action responses as quickly as possible, including pressing buttons or performing other operations. The time difference between the stimulus presentation and the response action was recorded to obtain the astronaut's reaction time. The average of the time differences obtained from different stimulus presentation scenarios was calculated to obtain the reaction value. The specific steps for the attention test were as follows: Different cognitive tasks were used to assess the astronauts' attention levels, including the line-connecting test, the digit search test, and the Stroop test. The line-connecting test required astronauts to connect matching items or graphics by drawing lines within a certain time limit, assessing the astronauts' hand-eye coordination and attention transfer ability, and obtaining the time required for the astronauts to complete the task, which was then calibrated as the completion value. The number search test assesses astronauts' selective attention and rapid orientation attention by requiring them to find a specific target number within a given time. The number of numbers found is evaluated and denoted as a specific value. The Stroop test assesses astronauts' inhibitory control and reaction inhibition abilities by requiring them to identify colors among presented text, where the text and its corresponding color do not match. The time or accuracy required to complete the task is used for evaluation, and a Stroop effect index is calculated to measure the degree of interference when identifying colors that do not match text. The time required to complete the task is calculated based on different preset Stroop effect indices, and the average is taken to obtain the effective completion value. The obtained reaction value, completion time value, specific value, and effective completion value are denoted as fy, ws, ts, and xw, respectively, and after normalization, are substituted into the following formula: To obtain the desired value YYZ, in the formula The preset weighting coefficients for reaction value, completion time value, special value, and effective completion value are defined by those skilled in the art. The reaction value, completion time value, and effective completion value are inversely proportional to the responsiveness value; the smaller these values, the larger the responsiveness value, indicating a higher reaction time and attention level for the astronaut in the simulated environment. The special value is directly proportional to the responsiveness value; the larger the special value, the larger the responsiveness value, with values ​​of 1.22, 0.97, 1.05, and 0.93 respectively. The obtained responsiveness value YYZ is used to measure the astronaut's reaction time and attention level in the simulated environment; the larger the YYZ value, the higher the astronaut's reaction time and attention level in the simulated environment.

[0068] Space orientation and navigation data: During training, astronauts' positioning and sense of direction in three-dimensional space are tested. Specific testing steps are as follows: Spatial awareness test: After prompting the astronaut to look around and close their eyes, their position and direction are slowly and randomly changed. After adjustment, the astronaut's reported position and facing direction are analyzed to determine if the reported position and direction are correct. Several tests are conducted to obtain the astronaut's judgment accuracy rate, which is used to measure the astronaut's spatial awareness ability; Coordinate system transformation ability test: A coordinate system transformation ability test is conducted by displaying a... The system uses two coordinate systems, prompting astronauts to switch to another. Input from the astronauts is collected to obtain the conversion error rate and usage time for a single test. After normalization, the conversion error rate is multiplied by the usage time to obtain the time error value. Multiple tests are conducted to obtain multiple time error values, and the average of these values ​​is calculated. This average time error value is used as a standard to measure the astronaut's coordinate system conversion ability; the higher the average time error value, the lower the astronaut's coordinate system conversion ability. Space memory training simulates various devices, instruments, and buttons controlling flight within the spacecraft using display equipment. First, different devices, instruments, and buttons are labeled with their specific names, functions, usage methods, and locations. Astronauts observe these labels for a preset time. Then, the labels are removed, and randomly selected devices and buttons are used to obtain the labels entered by the astronauts. The error rate of the astronauts' input is analyzed. This process is repeated multiple times to obtain several error rates. The average error rate is then calculated and used as a standard to measure the astronauts' spatial memory ability. A higher average error rate indicates a poorer spatial memory ability among the astronauts. The control and coordination test involves a pre-set flight path of standard difficulty and a simulated flight scenario. Astronauts perform simulated flight maneuvers, including propulsion, rotation, deceleration, and turning. After the simulation, the degree of overlap between the astronauts' simulated flight path and the pre-set path is analyzed. This degree of overlap is used as a standard to measure the astronauts' control and coordination abilities; a higher degree of overlap indicates stronger control and coordination capabilities. The obtained accuracy, mean timeout, mean error rate, and degree of overlap are then denoted as qe, wj, lj, and ch, respectively, and normalized before being substituted into the following formula: The position value WFZ is obtained; and the obtained position value WFZ is used as a standard to measure the astronaut's positioning and sense of direction. The larger the position value WFZ, the higher the astronaut's positioning and sense of direction.

[0069] After normalizing the obtained pose value WZZ, stress value, stress value YYZ, and orientation value WFZ, they are substituted into the following formula: The total score ZPZ is obtained, where YDZ is the adjustment value. The preset weighting coefficients for the attitude value WZZ, the adjustment value YDZ, the intention value YYZ, and the orientation value WFZ are defined by those skilled in the art, and can be set by them, for example, to be 1.22, 0.99, 1.06, and 0.92 respectively. The adjustment value YDZ, the intention value YYZ, and the orientation value WFZ are directly proportional to the total evaluation value, while the attitude value WZZ is inversely proportional to it. The larger the values ​​of the adjustment value YDZ, the intention value YYZ, and the orientation value WFZ, the larger the total evaluation value ZPZ. The obtained total evaluation value ZPZ is used as a standard for measuring the astronaut's comprehensive quality. The calculated total evaluation value ZPZ is then compared with several preset total evaluation value intervals. Each of these intervals corresponds to a simulation difficulty adjustment standard. Once the total evaluation value interval to which the astronaut's total evaluation value ZPZ belongs is determined, the corresponding simulation difficulty adjustment standard for that astronaut is obtained and sent to the adjustment module.

[0070] The adjustment module is used to receive the simulation difficulty adjustment standard transmitted by the evaluation module and to adjust the intensity of the simulation module accordingly.

[0071] Different difficulty adjustment standards correspond to different training intensities. Specific adjustments include: flight mission complexity, environmental simulation, instrument and control systems, and time settings. These are further categorized into levels corresponding to several difficulty adjustment standards. Flight mission complexity includes difficulty level, diversity level, and urgency level. Environmental simulation involves adjusting environmental simulation parameters in the flight simulator, including visual effects level, sound level, and gravity simulation level. These parameters can increase or decrease the astronaut's perception within the flight simulator. Instrument and control system settings are adjusted to increase or decrease the number and complexity of instruments, and to add or remove complex control systems and fault simulations, depending on the difficulty level. Time settings involve setting time limits for flight simulator missions, with different time limits set according to different training intensities. These specific adjustments are sent to the simulation module according to the corresponding difficulty adjustment standards to adjust the flight simulation intensity to suit the astronaut's overall competence.

[0072] The training suggestion module is used to provide training suggestions for astronauts' weaknesses based on an analysis of their overall qualities; specifically, it includes:

[0073] Obtain specific data for the parameters used to calculate the astronaut's overall performance rating (ZPZ), including: attitude value (WZZ), response value (YDZ), intention value (YYZ), and orientation value (WFZ). Compare these parameters with their corresponding preset parameter ranges. If any parameter falls outside the specified range, provide corresponding prompts to the astronaut. Specifically, if the attitude value (WZZ) is outside the preset parameter range, provide the astronaut with targeted body balance and adjustment training. This includes microgravity adaptation training: short-term weightlessness flight or underwater training to help the astronaut...

The time required to complete the task is recorded as the completion value. The digit search test involves astronauts finding a specific target number within a series of numbers, assessing their selective attention and rapid orientation attention. The number found within a specified time is used as the evaluation value. The Stroop test involves astronauts identifying colors among a series of presented text, where the text itself does not match the color it represents. This assesses their inhibitory control and reaction inhibition abilities, evaluating them through the time or accuracy required to complete the task. A Stroop effect index is calculated to measure the interference when the color and text do not match. The time required for each astronaut to complete the task is calculated based on different preset Stroop effect indices, and the average is taken to obtain the effective completion value. The obtained reaction value, completion value, specific value, and effective completion value are then labeled as fy, ws, ts, and xw, respectively, and after normalization, they are substituted into the following formula: To obtain the desired value YYZ, in the formula These are preset weighting coefficients for reaction value, completion value, specific value, and effective completion value, respectively. The location value is calculated in the following way: First, during the training process, the astronaut's positioning and sense of direction in three-dimensional space are tested. The specific test steps are as follows: The spatial awareness test is conducted by prompting the astronaut to look around and close his / her eyes. The astronaut's own position and direction are slowly and randomly changed. After the adjustment is completed, the astronaut's voice of the position and facing direction is obtained and analyzed to determine whether the position and direction reported by the astronaut are correct. Several tests are conducted to obtain the astronaut's judgment accuracy rate. This accuracy rate is used to measure the astronaut's spatial awareness ability. The coordinate system transformation capability test involves displaying one coordinate system and prompting the astronauts to transform to another coordinate system standard. The input results of the astronauts are collected to obtain the transformation error rate and usage time of a single test. After normalization, the transformation error rate is multiplied by the usage time to obtain the time error value. Multiple tests are conducted to obtain multiple time error values. The average time error value is obtained by averaging the multiple time error values. This average time error value is used as the standard to measure the astronaut's coordinate system transformation capability. Space memory training uses display devices to simulate various equipment, instruments, and buttons used to control flight inside a spacecraft. Different equipment, instruments, and buttons are first labeled with their specific names, functions, usage methods, and locations. Astronauts observe these devices for a preset time, then the labels are removed. Equipment, instruments, and buttons are randomly selected, and the labels entered by the astronauts are obtained. The error rate of the astronauts' input is analyzed. This process is repeated multiple times to obtain several error rates. The average error rate is then calculated from these error rates. The control and coordination test involves setting up a standard difficulty flight route and simulating flight scenarios. Astronauts perform simulated flight by operating the routes, including propulsion, rotation, deceleration, and turning. After the simulated flight is completed, the degree of overlap between the astronauts' simulated flight route and the preset flight route is analyzed. The obtained accuracy, mean timeout, mean error rate, and overlap are then labeled as qe, wj, lj, and ch, respectively, and normalized before being substituted into the following formula: To obtain the positional value WFZ; After normalizing the pose value WZZ, stress value YDZ, stress value YYZ, and orientation value WFZ, they are entered into the following formula: To obtain the total score ZPZ, These are the preset weighting coefficients for pose value, adjustment value, desired value, and orientation, respectively. The calculated total score ZPZ is then compared with several preset total score intervals. Each of these intervals corresponds to a simulation difficulty adjustment standard. Once the total score interval to which the astronaut's total score ZPZ belongs is determined, the corresponding simulation difficulty adjustment standard for that astronaut is obtained and sent to the adjustment module. The adjustment module is used to receive the simulation difficulty adjustment standard transmitted by the evaluation module and adjust the intensity of the simulation module accordingly. The different difficulty adjustment standards correspond to different training intensities. The specific adjustment items include: flight mission complexity, environmental simulation, instrument and control system and time settings, and the above items are divided into levels corresponding to several difficulty adjustment standards. The training suggestion module is used to provide training suggestions for astronauts' shortcomings based on the analysis of their comprehensive qualities.
