Description

Technical Field

[0001] This invention belongs to the field of monitoring technology, specifically relating to a real-time monitoring device for pilot health index. Background Technology

[0002] As the core of air transport, the physical health of pilots is directly related to flight safety and the operational quality of airlines. With increasingly heavy flight missions and longer flight times, pilots' physical fitness and health are facing severe challenges. Therefore, real-time monitoring of pilots' health indices and timely detection and intervention of potential health problems are of great significance for ensuring flight safety.

[0003] Chinese patent application number 202111392482.6 discloses a helmet for comprehensive monitoring of pilot health status. The helmet includes an ultra-fine elastic conductive bristle bundle, a blood flow detection mechanism, and a facial color detection mechanism. When the helmet is in use, the ultra-fine elastic conductive bristle bundle collects the pilot's electroencephalogram (EEG) signals, the blood flow detection mechanism detects the pilot's blood condition, and the facial color detection mechanism detects the pilot's facial color. Based on the pilot's EEG signals, blood condition, and facial color, the pilot's health index is determined, achieving real-time monitoring.

[0004] The above technology has the following problems: The ultra-fine elastic conductive bristle bundle, blood flow detection mechanism and facial color detection mechanism of the above structure are all integrated into the helmet. Although it can monitor the pilot's health index in real time, it increases the weight of the helmet, that is, increases the burden on the pilot's head during flight. If the flight time is long, it is easy to cause discomfort to the pilot. At the same time, the integration of the structure can easily cause visual obstruction for the pilot, which may pose a safety hazard.

[0005] Therefore, a real-time monitoring device for pilot health index is designed to solve the above problems. Summary of the Invention

[0056] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] A real-time pilot health index monitoring device, comprising:

[0058] The outer casing 1 is used to install the various structures of the device;

[0059] Mounting blocks 4 are provided in two, symmetrically fixed in the middle of the mounting sides at the top and bottom of the outer shell 1, for fixing the outer shell 1 to the fitting position on the aircraft.

[0060] There are two rotating ports 5, which are located on the camera side of the outer casing 1. They are used to install the camera structure of the device and also allow for the rotation and adjustment of the camera structure.

[0061] Camera 6, there are two of them, set in two rotating ports 5, for capturing images of the pilot's eye area;

[0062] A rotation drive mechanism is fitted between the outer casing 1 and the two cameras 6, and is used to drive the two cameras 6 to rotate and adjust their positions so that the two cameras 6 can capture images of the pilot's eye area.

[0063] The central processing unit 2, fixed to the top of the outer casing 1, is used to receive images of the pilot's eye area captured by the two cameras 6, process and analyze them, determine whether there are any abnormal conditions including fatigue and pain, and send an alarm command when there are abnormal conditions.

[0064] Alarm 3 is fixed to the top of the outer casing 1 and is used to receive alarm commands from the central processing unit 2 and provide audible and visual alarms to serve as a warning.

[0065] The central processing unit 2 is electrically connected to the camera 6, the rotation drive mechanism, and the alarm 3.

[0066] In this embodiment, please refer to the appendix. Figure 1-2 Before the device is used, the two mounting blocks 4 are fixed to the adapter position on the aircraft with screws, that is, the device is fixed to the adapter position on the aircraft.

[0067] When the device is in use, the central processing unit 2 controls the two cameras 6 to start, capture images, and transmit them to the central processing unit 2 for processing and analysis. If the central processing unit 2 determines that the two images do not represent the pilot's eye area, it controls the rotation drive mechanism to start, which drives the two cameras 6 to rotate. During this process, the two cameras 6 continue to capture images until the central processing unit 2 determines that the two images represent the pilot's eye area and stops. During the pilot's flight, the two cameras 6 continuously capture images and transmit them to the central processing unit 2 for processing and analysis. If the central processing unit 2 determines that the pilot's eye condition is fatigued or in pain, it sends an alarm command, and the alarm 3 sounds, so that timely action can be taken. If the central processing unit 2 determines that the results of the two images are different, it receives the two images from the next moment for reprocessing and analysis. During this process, if the pilot's eye area moves, the above correction work of the two cameras 6 is repeated to achieve real-time monitoring of the pilot's health index.

[0075] A follower mechanism is assembled between the outer casing 1 and the double-ended screw 105 to enable the double-ended screw 105 to rotate accordingly.

[0076] Two movable blocks 107 are provided and are symmetrically connected to the double-ended screw 105 via transmission nuts, and are used to move in the opposite direction when the double-ended screw 105 rotates;

[0077] Two movable frames 106 are provided, which are located outside the fixed block 102 and movable block 107 on the same side and are fixedly connected to the two cameras 6 to drive the two cameras 6 to rotate.

[0078] The first movable opening 109 is provided in four pairs, symmetrically opened on the two movable frames 106. The two fixed blocks 102 and the two movable blocks 107 are respectively located in the four first movable openings 109, so that the two movable frames 106 can be fitted over the two fixed blocks 102 and the two movable blocks 107 through the four first movable openings 109.

[0079] The second rotating shaft 108 is provided in eight parts, which are symmetrically connected to the top and bottom of the two fixed blocks 102 and the two movable blocks 107 by bearings, and are used to move with the two movable blocks 107.

[0080] The second movable opening 110 is provided in eight symmetrically arranged on the two movable frames 106. The other ends of the eight second rotating shafts 108 extend into the eight second movable openings 110 respectively, and are used to drive the two movable frames 106 to move with the movement of the eight second rotating shafts 108.

[0081] The central processing unit 2 is electrically connected to the drive mechanism.

[0082] In this embodiment, please refer to the appendix. Figure 2The rotation drive mechanism drives the connected circular plate 101 to rotate. The connected circular plate 101 drives the fixed shaft 103, the double-ended screw 105, and the follower mechanism to rotate. The fixed shaft 103 and the double-ended screw 105 respectively drive the connected fixed block 102 and the movable block 107 to rotate. The connected fixed block 102 and the movable block 107 respectively drive the connected second rotating shaft 108 to rotate. The connected second rotating shaft 108 drives the connected movable frame 106 to rotate. The connected movable frame 106 drives the connected camera 6 to rotate up and down in the corresponding rotating port 5. When the image captured by the camera 6 during this process contains the pilot's eye area but is not located in the center, the rotation of the circular plate 101 stops. The drive mechanism drives the follower mechanism to rotate, which in turn drives the double-headed screw 105 to rotate. During the rotation of the double-headed screw 105, the two movable blocks 107 move in opposite directions on the double-headed screw 105. The two movable blocks 107 drive the connected second rotating shaft 108 to move in the same direction. During the movement of the connected second rotating shaft 108, it moves within the corresponding second movable opening 110, which drives the two movable frames 106 to move left and right. The two movable frames 106 drive the two cameras 6 to rotate left and right within the corresponding rotating opening 5 until the image captured by the camera 6 during this process contains the pilot's eye area and is located in the center, thus realizing the drive for the two cameras 6 to rotate and adjust their positions.
