All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment 1

[0028] As Figures 1 - 5 shown, a non-contact biosensor proposed by the present invention includes a base 1, a sliding frame 4, and a sliding seat 13.

[0030] During the use of the non-contact biosensor of the present invention, an external power supply is connected. A person stands on the base 1, and the image sensor 8 performs non-contact collection on the person's body. The driving component is used to control the sliding seat 13 to rotate along the base 1, so that the image sensor 8 moves in a circular motion around the human body.

[0031] Furthermore, the lead screw component is used to control the slider 3 to perform lifting and lowering actions, so that the image sensor 8 moves up and down along the human body.

[0032] The image sensor 8 performs video collection on human body information, records features such as human activities, postures, and expressions, and extracts human body information through algorithm analysis and recognition.

[0033] Embodiment 2

[0034] As Figures 1 - 5 shown, a non-contact biosensor proposed by the present invention, compared with Embodiment 1, this embodiment further includes: a top plate 5 is installed at the top end of the sliding frame 4 through bolts, and a lighting lamp 6 is installed on the lower surface of the top plate 5. During the information collection process, the lighting lamp 6 works to illuminate the information collection area.

[0035] The drive assembly consists of a limit groove 9, a gear ring 10, a gear 12, a motor 14, and a limit block 15. The limit groove 9 is opened on the upper outer wall of the base 1. The limit block 15 is fixed on the inner surface of the slide base 13. The limit block 15 is slidably installed inside the limit groove 9. The gear ring 10 is fixed on the lower surface of the base 1. The motor 14 is fixed on the slide base 13. The gear 12 is fixed on the output end of the motor 14.
