[0057] Through the power transmission of the two limiting rings 9011, the L-shaped driving plate 903 can slide up and down to drive the six-rib transmission shaft 901, and under normal circumstances, the spring on the positioning shaft 902 can push the L-shaped driving plate 903 to keep it in the lower sliding state, so that the six-rib transmission shaft 901 remains in the use state of being inserted and driven by the worm wheel 801.

[0058] On the basis of example one, example two:

[0059] The T-shaped support rod 1 on which the L-shaped mounting rod 105 is installed is fixedly installed with a control box 6 near the reel 8, and the top end of the control box 6 is fixedly installed with an audible and visual alarm 7; the inside of the control box 6 is provided with an image recognition module, a motor control module and a breathing feature monitoring module, and the front side wall of the control box 6 is embeddedly installed with an LED display screen, the infrared visual camera 4 and the thermal imaging lens 5 are both in communication connection with the image recognition module, the image recognition module is in communication connection with the motor control module and the breathing feature monitoring module, the motor control module is in electrical connection with the motor 9, and the breathing feature monitoring module is in communication connection with the LED display screen and the audible and visual alarm 7.

[0060] The thermal imaging lens 5 is used for shooting the gas with heat exhaled from the mouth and nose of the monitored person, the thermal imaging lens 5 transmits the shot exhaled gas picture data to the image recognition module in real time, the image recognition module calculates and recognizes the breathing frequency of the monitored person according to the received exhaled gas picture data, and transmits the breathing frequency data to the breathing feature monitoring module in real time, the breathing feature monitoring module compares and calculates the actual breathing frequency data received by it with the standard breathing frequency preset in its internal program in real time, if the actual breathing frequency is less than the standard breathing frequency, it is determined that the breathing feature of the monitored person is unstable and unqualified, at this time, the breathing feature monitoring module triggers and starts the audible and visual alarm 7 to remind and warn, otherwise, it is determined that the breathing feature of the monitored person is stable and qualified, the audible and visual alarm 7 remains in the silent state of not being triggered, and the breathing feature monitoring module transmits and displays the breathing frequency data and the standard breathing frequency data on the LED display screen in real time, so as to be viewed by the monitored person or other accompanying personnel.

[0061] The infrared visual camera 4 is used to take pictures of the orientation and angle of the head of the monitored person in real time, and the picture data of the head is transmitted to the image recognition module in real time. The image recognition module calculates and identifies the orientation and angle of the head of the monitored person according to the received picture data, and judges whether the mouth and nose are aligned with the thermal imaging lens 5. When the head of the monitored person is turned or moved or rolled over, causing the mouth and nose to be misaligned with the thermal imaging lens 5, the image recognition module calculates and identifies the misalignment event in time and judges the misalignment orientation of the head, and transmits the misalignment orientation 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 misalignment orientation data, drives the infrared visual camera 4 and the thermal imaging lens 5 to rotate towards the side of the misaligned head, until the thermal imaging lens 5 is aligned with the mouth and nose of the monitored person again, to ensure the continuous and effective monitoring of the breathing characteristics of the monitored person by the thermal imaging lens 5. In this way, the thermal imaging lens 5 can be used for the monitored person's head movement and body rolling action, and can automatically follow the head movement to adjust the shooting angle, always aligning with the mouth and nose of the monitored person for shooting and monitoring. Compared with the prior art, the device can continuously, real-time, effectively and normally monitor the breathing characteristics of the monitored person, which is beneficial to improve the monitoring effect of the device.

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

[0063] The thermal imaging lens 5 is used to take pictures of the gas with heat exhaled from the mouth and nose of the monitored person. The thermal imaging lens 5 transmits the picture data of the exhaled gas to the image recognition module in real time. The image recognition module calculates and identifies the breathing frequency of the monitored person according to the received picture data of the exhaled gas, and transmits the breathing frequency data to the breathing characteristic monitoring module in real time. The breathing characteristic monitoring module compares the actual breathing frequency data received by it with the standard breathing frequency preset in its internal program in real time. If the actual breathing frequency is less than the standard breathing frequency, it is determined that the breathing characteristics of the monitored person are unstable and unqualified. At this time, the breathing characteristic monitoring module triggers the sound and light alarm 7 to remind and warn. Otherwise, it is determined that the breathing characteristics of the monitored person are stable and qualified, and the sound and light alarm 7 remains in a silent state that is not triggered. The breathing characteristic monitoring module transmits and displays the breathing frequency data and the standard breathing frequency data on the LED display screen in real time for the monitored person or other accompanying personnel to check.

[0064] The infrared visual camera 4 is used to take pictures of the orientation and angle of the head of the monitored person in real time, and the picture data of the head is transmitted to the image recognition module in real time. The image recognition module calculates and identifies the orientation and angle of the head of the monitored person according to the received picture data, and judges whether the mouth and nose are aligned with the thermal imaging lens 5. When the head of the monitored person is turned or moved or rolled over, causing the mouth and nose to be misaligned with the thermal imaging lens 5, the image recognition module calculates and identifies the misalignment event in time and judges the misalignment orientation of the head, and transmits the misalignment orientation 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 misalignment orientation data, drives the infrared visual camera 4 and the thermal imaging lens 5 to rotate towards the side where the head is misaligned, until the thermal imaging lens 5 is aligned with the mouth and nose of the monitored person again, to ensure that the whole device can continuously and effectively monitor the breathing characteristics of the monitored person.
