DETAILED DESCRIPTION

[0029] The present invention is further described below in conjunction with embodiments, which are only 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 protection scope of the present invention.

[0030] See also Figure 1 as well as Figure 2 As shown, this embodiment discloses a cockpit infrared vision training device, including a training cabin, which is used to be installed inside a training room and used to perform simulated flight inside the training room;

[0031] The training cabin is equipped with an infrared imaging unit, a display unit, a data processing unit and a training management unit. The infrared imaging unit is connected to the data processing unit, which is in turn connected to the display unit. The infrared imaging unit is used to capture infrared images of the environment, and the display unit is used to convert the infrared images into a visual interface. The data processing unit is used to process infrared image data and obtain the infrared image clarity I and the environment complexity C. The training management unit is used to record the pilot's training effect index E.

[0032] Among them, the training effect index E is calculated by the following formula:

[0033]

[0034] Among them, R is the pilot ability response index, D is the training time, T is the training load, and Q is the external factor.

[0035] The present invention mainly includes a training cabin, which is used to be installed inside the training room and used to simulate flight inside the training room. First, the trainee enters the training cabin, and then turns off the lights inside the training room. At this time, the trainee uses an infrared imaging unit to perform infrared imaging of the simulated scene inside the training room, which can provide a clear field of view at night or under low visibility conditions, and transmits the data to a data processing unit. The data processing unit is responsible for processing infrared image data, including image enhancement, target recognition, and ranging functions, so as to help pilots better understand and analyze the environment. After processing the data, the data processing unit transmits the processed data information to a display unit, and the display unit converts the infrared image into a visual interface. The trainee views the environmental information through the visual interface, and then performs simulated operations in the training room by operating the training cabin. During the training process, the data processing unit obtains the clarity of the infrared image and the environmental complexity in the training room, and records the ability reaction index R, training time D, training load T, and external factors Q of the trained pilot, and uses the formula The pilot's training effect index E is calculated. Finally, the training management unit records the pilot's training effect index E to complete the final simulation training. The advantage of this setting is that the pilot's training results can be accepted. By accepting the pilot's training effect index E, the pilot can be urged to make progress, thereby making the overall training effect of the infrared visual training equipment better.

[0036] In some embodiments, the infrared image clarity I is calculated by the following formula: Where R max is the theoretical maximum resolution of the system, R min is the theoretical minimum resolution of the system, R actual This is the resolution obtained from actual testing.

[0037] As an optional implementation, in this embodiment, the infrared imaging unit is specifically an infrared camera, and the theoretical maximum resolution of the infrared camera is 640dpi, and the theoretical minimum resolution is 32dpi. (dpi is calculated by the formula Calculation is performed), the model of the infrared camera in this embodiment is: FL IR A615, and the actual resolution of the FL I RA615 infrared camera is 128 dpi. Therefore, after substituting into the formula, when FL IR A615 is selected, the infrared image clarity I of FL I RA615 is 1.8.

[0038] In some embodiments, the environment complexity C is calculated by the following formula: Among them, N obstacles is the number of obstacles in the environment, N obstacles It can be obtained from the display unit, N total is the maximum number of all obstacles that may exist in the environment, W factor The weight of the weather factor, ranging from 0 to 1, 0 represents normal weather, and 1 represents rainy or foggy weather.

[0039] As an optional implementation, in this embodiment, the maximum number of obstacles set by the staff in the training field is 20, and the number of obstacles actually existing in one training is 5. After substituting into the formula, on a sunny day, the environmental complexity is 0.25, and on a rainy or foggy day, the environmental complexity is 1.25;

[0040] In some embodiments, a timer is provided inside the training cabin, and the timer is installed inside the training cabin through an installation component, and the timer is used to time the training time D;

[0041] It is found in the continuous visual training that the pilots in training often place the timer randomly when timing. This results in the pilots in training not being able to find the position of the timer after the training, resulting in errors in the timing of the timer. Therefore, based on the above problem, the present invention provides an installation component, the purpose of which is to solve the problems of actual installation and use.

[0042] The mounting assembly includes a mounting block 101, a rotating device and a fixing device. The mounting block 101 is used to be mounted inside the training cabin. The rotating device is rotatably mounted on the mounting block 101. The fixing device is mounted on the rotating device. The rotating device includes a first rotating assembly, a second rotating assembly and a third rotating assembly. The first rotating assembly is rotatably connected to the mounting block 101. The second rotating assembly is rotatably mounted on the first rotating assembly. The third rotating assembly includes a rotating frame 102 and a rotating rod 103 arranged at both ends of the rotating frame 102. The rotating rod 103 is rotatably connected to the second rotating assembly. The rotating frame 102 is used to install a timer. The fixing device The device includes a pressing plate 104, a hinged portion 105, a locking rod 106, a cushion block 107 and a locking sleeve 108. The hinged portion 105 and the cushion block 107 are fixedly mounted on the rotating frame 102. The pressing plate 104 is hinged on the hinged portion 105. The locking rod 106 is mounted on the pressing plate 104. A locking hole 109 is arranged on the cushion block 107. The outer surface of the locking sleeve 108 is threadedly connected to the inner surface of the locking hole 109. The locking rod 106 is used to be placed inside the locking hole 109. The outer surface of the locking rod 106 is threadedly connected to the inner surface of the locking sleeve 108. A slot is arranged at the rear of the timer. The pressing plate 104 is used to fix the position of the timer after passing through the slot.

[0043] Among them, the first rotating component includes a rotating rod 121 and a connecting rib 122, the rotating rod 121 is rotatably set on the mounting block 101, the other end of the connecting rib 122 is connected to the rotating rod 121, and the other end is connected to the second rotating component; the second rotating component includes a rotating cylinder 123, a rotating shaft 124 and a support platform 125, the rotating cylinder 123 is fixedly connected to the connecting rib 122, the support platform 125 is arranged above the rotating cylinder 123 and forms an integrated structure with the rotating cylinder 123, the rotating shaft 124 is connected to the rotating cylinder 123 and the rotating beam of the support platform 125, the end of the rotating shaft 124 is provided with a bracket 126, and the rotating frame 102 is rotatably mounted on the bracket 126.

[0044] The locking rod 106 on the pressing plate 104 is screwed into the locking hole 109, and the locking sleeve 108 is rotated. At this time, the outer surface of the locking sleeve 108 is threadedly connected with the locking hole 109, and the position of the locking rod 106 is fixed after the inner surface of the locking sleeve 108 is threadedly connected with the outer surface of the locking rod 106. Then, the pressing plate 104 presses the timer onto the rotating frame 102 to fix the timer. After the installation of the timer is completed, when the trainee needs to use the timer, the trainee pulls the connecting rib 122, and the integrated structure formed by the connecting rib 122 and the rotation enables the rotating rod 121 to rotate on the mounting block 101. At this time, the second rotating assembly rotates on the mounting block 101 as a whole. When it is necessary to adjust the lateral rotation angle of the timer, the trainer rotates the second rotating component. At this time, when the user needs to rotate the second rotating component, he first rotates the shaft 124. The shaft 124 drives the support platform 125 to rotate above the rotating cylinder 123. After the support platform 125 rotates, it drives the bracket 126 to rotate together, so that the rotating frame 102 rotates with the support platform 125. After adjusting the lateral position, it is also necessary to adjust the pitch angle of the timer. At this time, the trainer toggles the rotating frame 102. At this time, the two ends on both sides of the rotating frame 102 rotate on the second rotating component, thereby adjusting the pitch angle of the timer, and finally completing the adjustment of the angle of the timer. The advantage of this arrangement is that the timer can be fixed by the pressure plate 104, and the angle of the timer can be adjusted by the first rotating component, the second rotating component and the third rotating component, so that the trainer can better use the timer.

[0045] In some embodiments, the pilot capability reaction index R is calculated by the following formula: Among them, T max is the theoretical maximum value of the reaction time, T min is the theoretical minimum value of the reaction time, T avg It is the average reaction time of the pilot within a certain period of time.

[0046] As an optional implementation method, during the pilot's training, the data of each time will be recorded. Assuming that the theoretical maximum reaction time is 10S, the theoretical minimum reaction time is 2S, and the average reaction time within a certain period of time is 6S, after substituting into the formula, the R is 0.5, which means that the pilot's ability reaction index R is 0.5.

[0047] In some embodiments, the external factor Q is calculated by the following formula: Among them, P is the impact score of external factors on training, P max Score the maximum possible impact.

[0048] As an optional implementation, in this embodiment, the maximum impact score is 5, and the score of the external factor evaluation is evaluated according to the actual pilot. Assuming that the pilot believes that the score of the external factor evaluation is 3, after substituting it into the formula, the external factor Q is 0.6.

[0049] As an optional implementation, in this embodiment, before the pilot performs a flight mission, he or she needs to undergo a lot of training, among which infrared vision training is an indispensable training. In this training, the following are applied:

[0050] The infrared imaging unit is an infrared camera in the prior art, and its model is: DS-2CD2347G1-L; the maximum resolution is 2688x 1520 pixels, and the minimum resolution is 640x 480 pixels;

[0051] The display unit is a portable display in the prior art, and its model is: ZenScreen Go MB16AP, and its size is 24-14 inches.

[0052] The data processing unit is a host in the prior art, equipped with a GPU, and the model is NVID IA's Tesla. When pilot A is training in the training cabin, he first installs the timer through the installation structure. When the training starts, the timer is turned on. The timer counts the pilot's training time. The infrared camera performs infrared imaging of the simulated scene inside the training room. The resolution of the infrared camera DS-2CD2347G1-L is 2688x 1520 pixels. The infrared camera transmits data to the host, and the GPU processes the infrared image data and transmits the processed data to the portable display. The size of the portable display is 14 inches. Therefore, R is calculated by the above dpi calculation formula. actual =145.5, where R max =192(2688 / 14), R min =63(1520 / 24), after substituting it into the formula for calculating the infrared image clarity I,

[0053] The infrared image clarity is calculated to be 0.88, and then the environmental complexity C is calculated. In the training field, the maximum number of obstacles actually prepared to be set is 20, and the number of obstacles actually existing in this training is 5. After substituting into the formula, on a sunny day, the environmental complexity is 0.25, and on a rainy or foggy day, the environmental complexity is 1.25; when pilot A finishes the training, the timer is stopped. The training time this time is 1200s, so the training time D = 0.2 (20min); the theoretical maximum value of the reaction time for humans to react to things is 0.3s, and the theoretical minimum value of the reaction time is 0.1s. In previous training, since the data of each training will be recorded, the average reaction time of pilot A is 0.22s. Therefore, through the above calculation formula for the pilot ability reaction index It can be seen from the formula that pilot A's pilot ability reaction index is 0.4, and the training load T is the difficulty coefficient of training, the index is 1-5, and the individual coefficient of this training is 2. Finally, the external factor Q needs to be obtained. The impact of external factors is 1-5, among which the external factors include: poor sleep quality, illness, continuous training times more than 10 times, total training times not exceeding 10 times, and strenuous exercise, each accounting for 1, and the maximum impact score is 5. Pilot A played badminton for 3 hours the night before, the total number of training times did not exceed 10 times, and did not train 10 times in a row. In the case of good physical condition and good sleep quality, the impact score of external factors on training P is 2, which is 5. Therefore, the external factor Q is 0.4 after calculation by the above formula; Finally, after obtaining all the data, it is calculated when it is sunny:

[0054]

[0055] Therefore, the training effect index of pilot A is E = 0.66;

[0056] In the next training, when pilot A is training in the training cabin, he first installs the timer through the installation structure. At the beginning of the training, he turns on the timer, and the timer counts the pilot's training time. There is equipment inconvenience, so the infrared image clarity = 0.88, and then the environmental complexity C is calculated. In the training field, the maximum number of obstacles actually prepared to be set is 20, and the number of obstacles actually existing in this training is 5. After substituting into the formula, on a sunny day, the environmental complexity is 0.25. When pilot A finishes the training, he stops counting the timer. The training time this time is 1200s, so the training time D = 0.2 (20min); the theoretical maximum value of the reaction time for humans to react to things is 0.3s, and the theoretical minimum value of the reaction time is 0.1s. In previous training, since the data of each training session was recorded, the average reaction time of pilot A was improved to 0.22s. Therefore, through the above calculation formula for the pilot ability reaction index, it can be known that pilot A's pilot ability reaction index is 0.4, and the training load T is the difficulty coefficient of training, the index is 1-5, and the individual coefficient of this training is 3. Finally, the external factor Q needs to be obtained. Pilot A did not do strenuous exercise the night before, the total number of training sessions exceeded 10 times, and he did not train 10 times in a row. He occasionally felt cold and had poor sleep quality. The impact score of external factors on training P was 3, and the score was 5. Therefore, the external factor Q was calculated by the above formula to be 0.6; Finally, after obtaining all the data, it was calculated that on a sunny day:

[0057]

[0058] Therefore, the training effect index of pilot A is E = 0.62;

[0059] Use the above method and the control variable method by analogy, changing only one parameter value at a time, and conducting continuous training. Finally, we can compare the calculated training effect index E to see which factors have the greatest impact on the pilot's training effect index E, find out the most critical factors that affect the pilot's flight, and finally avoid this factor when performing the flight mission, so that the pilot can perform the flight mission better.
