[0039] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0040] Please refer to Figures 1 to 8 ;

[0041] Embodiment 1:

[0042] The present invention provides a non-contact breathing characteristic monitoring device, comprising: a T-shaped support rod 1, wherein the T-shaped support rod 1 is symmetrically arranged at two locations.

[0043] A rotatable reel 8 and an obliquely welded L-shaped mounting rod 105 are respectively installed on the inner and outer sides of the top end of a T-shaped support rod 1. An obliquely supported worm 104 is rotatably arranged near the L-shaped mounting rod 105 on the T-shaped support rod 1, and one end of the rotating shaft of the reel 8 is protrudingly extended and is fitted with a worm wheel 801, and the worm 104 is meshed with the worm wheel 801 for transmission.

[0044] The worm 104 and the worm wheel 801 together form a worm gear mechanism.

[0045] The rod section of the L-shaped mounting rod 105 away from the T-shaped support rod 1 is sequentially installed with two gear plates 106 and a driving short shaft 107 from top to bottom, wherein the two gear plates 106 are arranged side by side and mesh with each other, and the driving short shaft 107 is drivingly connected to the gear plate 106 on the lower side; the rod section of the L-shaped mounting rod 105 connected to the T-shaped support rod 1 is fixedly installed with a motor 9, and a hexagonal transmission shaft 901 is slidably installed through the inside of the rotating shaft of the motor 9, and the hexagonal transmission shaft 901 is normally plugged and matched with the worm 104, and when the hexagonal transmission shaft 901 slides upward, it is pulled away from the worm 104 and plugged and matched with the driving short shaft 107;

[0046] Through the worm gear mechanism, when the hexagonal transmission shaft 901 and the worm 104 are plugged in for transmission, the motor 9 can drive the reel 8 to rotate forward and reversely to implement winding and unwinding. When the hexagonal transmission shaft 901 and the driving short shaft 107 are plugged in for transmission, the motor 9 can rotate to drive the two gear plates 106 to rotate synchronously in the opposite direction.

[0047] An incomplete track ring 101 is welded to the top of the two T-shaped support rods 1, and an arc-shaped sliding sleeve 103 is slidably mounted on the incomplete track ring 101. An infrared vision camera 4 and a thermal imaging lens 5 are installed at intervals on the arc-shaped sliding sleeve 103 on one side facing the center of the incomplete track ring 101 and fixed by bolts.

[0048] A wire rope 802 is wound on the reel 8, and the head end of the wire rope 802 is connected and fixed to the head end of the arc-shaped sliding sleeve 103; a tension spring 2 is hung between the top end of the T-shaped support rod 1 and the tail end of the arc-shaped sliding sleeve 103.

[0049] When the reel 8 rotates forward to reel the wire rope 802, the wire rope 802 can be used to pull the arc sleeve 103 to slide along the incomplete track ring 101 toward the reel 8. When the reel 8 reverses to unwind the wire rope 802, the tension spring 2 can be used to pull the arc sleeve 103 to slide along the incomplete track ring 101 away from the reel 8. Then, through the wire rope 802 and the tension spring 2, the reel 8 can drive the arc sleeve 103, the infrared vision camera 4 and the thermal imaging lens 5 to reciprocate along the incomplete track ring 101 when reeling and unreeling in forward and reverse rotations to adjust the shooting angle. The wire rope 802 and the tension spring 2 cooperate with each other to pull in reverse directions to position the arc sleeve 103, the infrared vision camera 4 and the thermal imaging lens 5 in the use posture after the angle adjustment.

[0050] A track groove 102 with a U-shaped cross-section is provided on the vertical support rod section of the T-shaped support rod 1 on which the tension spring 2 is installed and the incomplete track ring 101. The steel wire 802 and the arc-shaped sliding sleeve 103 are arranged in two parts on the track groove 102 located at the head and tail ends of the arc-shaped sliding sleeve 103.

[0051] The top of the rotating shaft of the lower gear disk 106 and the top of the driving short shaft 107 are both equipped with synchronous wheels, and the two synchronous wheels are tensioned with a synchronous belt 3; the bottom sides of the two gear disks 106 are fixed with cleaning sponges 10 by Velcro, and when the infrared vision camera 4 and the thermal imaging lens 5 slide close to the reel 8, the lenses at the head end are respectively in friction and compression contact with the two cleaning sponges 10.

[0052] The two gear plates 106 can rotate to drive the two cleaning sponges 10 to wipe and clean the front end lenses of the infrared vision camera 4 and the thermal imaging lens 5 that are in squeeze contact with the two cleaning sponges 10 .

[0053] The hexagonal transmission shaft 901 is a power clutch mechanism between the motor 9 and the reel 8 and the two gear plates 106. Through the transmission of the hexagonal transmission shaft 901, the motor 9 can be used as a common driving motor to drive the infrared vision camera 4 and the thermal imaging lens 5 to adjust the shooting angle and drive the two cleaning sponges 10 to rotate and wipe for cleaning. Compared with the prior art, this eliminates the need to additionally configure a driving motor for the two cleaning sponges 10, which helps to reduce the overall manufacturing cost of the monitoring device.

[0054] The hexagonal transmission shaft 901 tilts upward and slides to connect with the driving short shaft 107 for transmission, and at the same time, it is decoupled from the power of the worm 104. The hexagonal transmission shaft 901 tilts downward and slides to connect with the worm 104 for transmission, and at the same time, it is decoupled from the power of the driving short shaft 107. This saves the trouble of manually decoupling the power of the hexagonal transmission shaft 901 and the infrared vision camera 4, the thermal imaging lens 5 or the two cleaning sponges 10 when switching the transmission of the infrared vision camera 4, the thermal imaging lens 5 and the two cleaning sponges 10, and is easy to operate and use.

[0055] The worm gear 801 , the hexagonal transmission shaft 901 and the driving stub shaft 107 are located on the same axis.

[0056] A positioning shaft 902 is welded on the circumferential shell wall of the motor 9, and the positioning shaft 902 is slidably installed with an L-shaped driving plate 903 through a spring push; the top part of the hexagonal transmission shaft 901 is welded with two limit rings 9011 at intervals up and down, and the part of the hexagonal transmission shaft 901 located between the two limit rings 9011 is a circular structure, and the circular part of the hexagonal transmission shaft 901 is rotatably matched with the head end of the L-shaped driving plate 903.

[0057] Through the power transmission of two limit rings 9011, the L-shaped drive plate 903 can drive the hexagonal transmission shaft 901 to slide up and down, and under normal conditions, the spring on the positioning shaft 902 can push the L-shaped drive plate 903 to remain in a downward sliding state, so that the hexagonal transmission shaft 901 remains in a state of use for plug-in transmission with the worm gear 801.

[0058] Based on the first embodiment, the second embodiment:

[0059] A control box 6 is fixedly installed on the T-shaped support rod 1 on which the L-shaped mounting rod 105 is installed, near the reel 8, and a sound and light alarm 7 is fixedly installed on the top of the control box 6; an image recognition module, a motor control module and a respiratory characteristic monitoring module are arranged inside the control box 6, and an LED display screen is inlaid and installed on the front side wall of the control box 6, the infrared visual camera 4 and the thermal imaging lens 5 are both communicatively connected with the image recognition module, the image recognition module is communicatively connected with the motor control module and the respiratory characteristic monitoring module, the motor control module is electrically connected with the motor 9, and the respiratory characteristic monitoring module is communicatively connected with the LED display screen and the sound and light alarm 7.

[0060] The thermal imaging lens 5 is used to capture the hot gas exhaled from the mouth and nose of the monitored person. The thermal imaging lens 5 transmits the captured exhaled gas image data to the image recognition module in real time. The image recognition module calculates and identifies the respiratory frequency of the monitored person based on the received exhaled gas image data, and transmits the respiratory frequency data to the respiratory characteristic monitoring module in real time. The respiratory characteristic monitoring module compares the actual respiratory frequency data it receives with the standard respiratory frequency preset in its internal program in real time. If the actual respiratory frequency is less than the standard respiratory frequency, it is determined that the respiratory characteristics of the monitored person are unstable and unqualified. At this time, the respiratory characteristic monitoring module triggers and starts the sound and light alarm 7 to remind and warn. Otherwise, it is determined that the respiratory characteristics of the monitored person are stable and qualified. The sound and light alarm 7 remains in a silent state without being triggered, and the respiratory characteristic monitoring module transmits the respiratory frequency data and the standard respiratory frequency data in real time and displays them on the LED display screen for viewing by the monitored person or other accompanying personnel.

[0061] The infrared visual camera 4 is used to monitor the position and angle of the monitored person's head in real time, and transmits the captured head position and angle image data to the image recognition module in real time. The image recognition module calculates and recognizes the position and angle of the monitored person's head based on the received image data, and determines whether the mouth and nose are aligned with the thermal imaging lens 5. When the monitored person's head swings or turns over, causing the mouth and nose to be misaligned with the thermal imaging lens 5, the image recognition module promptly calculates and recognizes the misalignment event and determines the side tilt position of the head, and transmits the side tilt position data of the head to the motor control module. The motor control module controls the motor 9 based on the received side tilt position data. By rotating forward or reverse, the infrared vision camera 4 and the thermal imaging lens 5 are driven to rotate toward the side of the tilted head until the thermal imaging lens 5 is aligned with the mouth and nose of the monitored person again, so as to ensure that the thermal imaging lens 5 continuously and effectively monitors the respiratory characteristics of the monitored person. In this way, the thermal imaging lens 5 can adapt to the movement of the monitored person's head and the turning over of the whole body, and can automatically follow up the movement of the head to perform follow-up rotation and sliding adjustment of its shooting angle, and always align with the mouth and nose of the monitored person to perform shooting and monitoring. Compared with the existing technology, the device can continuously, real-time, effectively and normally monitor the respiratory characteristics of the monitored person, which is beneficial to improving the monitoring effect of the device.

[0062] The working principle of this embodiment is as follows: when in use, the device is pushed as a whole close to the bed, and the two T-shaped support rods 1 are inserted into the bedside cover, and the infrared visual camera 4 and the thermal imaging lens 5 are aimed at the mouth and nose of the monitored person lying on the bed.

[0063] The thermal imaging lens 5 is used to capture the hot gas exhaled from the mouth and nose of the monitored person. The thermal imaging lens 5 transmits the captured exhaled gas image data to the image recognition module in real time. The image recognition module calculates and identifies the respiratory frequency of the monitored person based on the received exhaled gas image data, and transmits the respiratory frequency data to the respiratory characteristic monitoring module in real time. The respiratory characteristic monitoring module compares the actual respiratory frequency data it receives with the standard respiratory frequency preset in its internal program in real time. If the actual respiratory frequency is less than the standard respiratory frequency, it is determined that the respiratory characteristics of the monitored person are unstable and unqualified. At this time, the respiratory characteristic monitoring module triggers and starts the sound and light alarm 7 to remind and warn. Otherwise, it is determined that the respiratory characteristics of the monitored person are stable and qualified. The sound and light alarm 7 remains in a silent state without being triggered, and the respiratory characteristic monitoring module transmits the respiratory frequency data and the standard respiratory frequency data in real time and displays them on the LED display screen for viewing by the monitored person or other accompanying personnel.

[0064] The infrared visual camera 4 is used to monitor the position and angle of the monitored person's head in real time. It transmits the captured head position and angle image data to the image recognition module in real time. The image recognition module calculates and identifies the position and angle of the monitored person's head based on the received image data, and determines whether the mouth and nose are aligned with the thermal imaging lens 5. When the monitored person's head swings or turns over, causing the mouth and nose to be misaligned with the thermal imaging lens 5, the image recognition module promptly calculates and identifies the misalignment event and determines the side-tilted position of the head, and transmits the side-tilted position data of the head to the motor control module. The motor control module controls the motor 9 to rotate forward or reverse according to the received side-tilted position data, and drives the infrared visual camera 4 and the thermal imaging lens 5 to rotate toward the side of the head that is tilted, until the thermal imaging lens 5 is aligned with the mouth and nose of the monitored person again, so as to ensure that the device as a whole can continuously and effectively monitor the respiratory characteristics of the monitored person.
