Description

Technical Field

[0001] The present invention relates to the field of facial monitoring equipment, in particular to a facial abnormal state monitoring device based on visual recognition. Background Art

[0002] Facial expression is one of the important ways of human emotional communication. Facial micro-expressions are spontaneous and difficult to control, and can truly reflect a person's inner emotional state. However, traditional emotion recognition methods mainly rely on manual observation and empirical judgment, which are highly subjective, inefficient, and difficult to capture instantaneous micro-expressions. In modern life, due to the pressure of work and life, parents may not be able to always be with their children, especially when coaxing their children to sleep at night. Therefore, some parents may look for solutions that can replace the parents' voice to coax their children to sleep, so that when they cannot be with their children in person, the children can still get comfort and a sense of security.

[0027] In this embodiment, a camera 13 is fixedly installed at one end of the tablet computer 12, a speaker 14 is fixedly installed at the other end of the tablet computer 12, a display screen 15 is fixedly installed on the tablet computer 12, a heat dissipation groove 16 is opened on the movable plate 10, and the heat dissipation groove 16 cooperates with the tablet computer 12, a heat dissipation hole 17 is opened on the side of the motor seat 7, a motor cavity 35 is opened inside the motor seat 7, and a rotating motor 36 is fixedly installed inside the motor cavity 35, and an output shaft 18 is installed on the rotating motor 36, and one end of the output shaft 18 is fixed on the movable rod 6. The rotating motor 36 drives the limiting seat 8 to rotate as a whole, and the limiting seat 8 rotates to change the inclination angle of the tablet computer 12, so that the camera 13 can irradiate different positions for monitoring.

[0028] In this embodiment, a tension mechanism 19 is fixed on the inner wall of the slot 9, and the tension mechanism 19 is a tension spring. The tension spring drives the movable plate 10 downward. After the movable plate 10 moves downward, the slot 9 limits and fixes the tablet computer 12. One end of the tension mechanism 19 is fixed on the movable plate 10. A limit assembly 20 is movably installed inside the slot 9. The limit assembly 20 includes a threaded hole 21. The threaded hole 21 is opened on the limit seat 8. A support tube 22 is rotatably installed inside the threaded hole 21. The support tube 22 is opened The support tube 22 is rotatably mounted inside the threaded hole 21 through the external thread 23. A fixing hole 24 is opened inside the support tube 22. A movable column 25 is movably installed inside the fixing hole 24. A fixing plate 26 is fixed to one end of the movable column 25.

When the support tube 22 limits the movable plate 10, the movable column 25 moves upward to push the movable plate 10 upward, and the movable plate 10 pushes the tablet computer 12 to rise, thereby facilitating the horizontal sliding of the tablet computer 12.

[0029] In this embodiment, a support mechanism 28 is fixed inside the slide slot 27, and the support mechanism 28 is a support spring. The support spring pushes the movable column 25 to move downward, and the movable column 25 quickly returns to its original position after losing the thrust. A slider 29 is fixed at one end of the support mechanism 28, and one end of the slider 29 is fixed to the movable column 25.

The height of the movable plate 10 is limited by the support tube 22. The support tube 22 is later rotated inside the threaded hole 21 to adjust the height of the support tube 22 leaking out of the slot 9. The height of the movable plate 10 is adjusted by the difference in the height of the support tube 22 leaking out, and the depth of the upper and lower misalignment between the tablet computer 12 and the top of the limiting seat 8 is adjusted. After the tablet computer 12 enters the inside of the slot 9, it is effectively hidden and protected to avoid external The tablet computer 12 is damaged by the collision force. The App on the external mobile phone can control the operation of the driving motor 31 and the rotating motor 36. The driving motor 31 drives the rotating seat 3 to rotate. The rotating seat 3 rotates to change the direction facing the tablet computer 12. The rotating motor 36 drives the limit seat 8 to rotate to adjust the tilt direction of the tablet computer 12. When the tablet computer 12 is in use, the user can face the display screen 15 and operate and learn by himself. Through learning, the social skills of children with autism can be gradually improved. In addition, the tablet computer 12 has a voice interaction function, which can respond to children's voice commands and has built-in educational games to promote children's cognitive development and social skills learning. In addition, when you do not want the child to use the tablet computer 12 too much, you can start the rotating motor 36 to drive the display screen 15 to rotate so that the display screen 15 faces the support seat 4. In the later stage, the tablet computer 12 cannot be removed by the limit component 20. The movable rod 6 is used to limit and fix the tablet computer 12 twice to meet the use in different situations.
