The face recognition device in this embodiment is completely consistent with the face recognition system in the prior art. The technical solution of this embodiment only adjusts the height of the face recognition device for different heights to improve the recognition speed and the recognition accuracy;

[0029] like Figure 1 As shown, in order to allow people to pass through in an orderly manner, two groups of partitions 2 are fixedly connected to the upper wall of the platform 1. The two groups of partitions 2 are distributed on the left and right, and a passage for people to pass is formed between the two groups of partitions 2. The upper wall of the right group of partitions 2 is fixedly connected to a cross arm 4 through a column 3. The column 3 is located on the upper wall of the partition 2 and is located near the front side of the partition 2. The cross arm 4 is fixedly connected to the end of the column 3 away from the partition 2 and extends toward the left side of the column 3. The lower wall of the cross arm 4 is provided with a height detection structure for detecting the height of people passing through the two groups of partitions 2. The height detection structure is a distance sensor 5. The distance sensor 5 is fixedly connected to the lower wall of the cross arm 4. The distance sensor 5 is located in the middle of the left and right directions of the passage in a top-down projection. A walking passage is formed by the two groups of partitions 2. When people pass by, the left and right positions are restricted, so that they must pass through the detection range of the distance sensor 5 when walking. The height of a person can be identified relatively quickly through the distance sensor 5. The distance sensor 5 is a common technology on the market and is commonly found in various devices that automatically detect height and weight.

[0030] like Figure 1 , Figure 2As shown, in order to facilitate the display screen 10 to move up and down to adjust the height position, the upper walls of the two groups of partitions 2 and near the rear wall are fixedly connected with the equipment box 7 through two groups of support plates 6, the inner front wall of the equipment box 7 is distributed left and right and is slidably connected with two groups of slide bars 8 in sequence, the inner front wall of the equipment box 7 is distributed left and right and is fixedly connected with two groups of slide rails 12 in sequence, the rear walls of the two groups of slide rails 12 are provided with slide grooves, the two groups of slide bars 8 are slidably connected to the inner side walls of the two groups of slide grooves, and the slide bars 8 can slide up and down along the slide grooves of the rear walls of the slide rails 12;

[0031] like Figure 1 , Figure 2 As shown, in order to drive the display screen 10 to rise and fall quickly to adjust the height, the display screen 10 is fixedly connected to the front wall of the two groups of slide bars 8 and is located at one end away from the equipment box 7. A height adjustment structure for driving the slide bar 8 to rise and fall to adjust the height range of the camera 11 on the display screen 10 is provided between the inner front wall of the equipment box 7 and the slide bar 8. The height adjustment structure is an electric push rod 9, which is fixedly connected to the inner front wall of the equipment box 7 through two groups of fixing seats 13. The electric push rod 9 is located between the two groups of slide bars 8. A connecting block 14 is fixedly connected to the opposite side of the two groups of slide bars 8 and located at one end away from the equipment box 7. The end of the extended shaft of the electric push rod 9 is fixedly connected to the connecting block 14. The control device controls the extended length of the extended shaft of the electric push rod 9 according to the height information of the person detected by the distance sensor 5 until the display screen 10 is aligned with the head of the person. Compared with the previous adjustment of the pitch angle to adapt to the form of the face, the recognition speed is faster and more accurate.

[0032] like Figure 3 As shown, in order to prevent the electric push rod 9 from accidentally extending out and causing bumps and injuries when a person passes under the display screen 10, a protective structure for detecting whether a person passes by is provided on the lower wall of the display screen 10 and the side opposite to the platform 1. The protective structure includes two groups of photoelectric sensors 15. The two groups of photoelectric sensors 15 are respectively provided between the platform 1 and the side opposite to the display screen 10. A signal connection is formed between the two groups of photoelectric sensors 15. When a person passes by, the signal is cut off, so that the control device controls the electric push rod 9 not to extend at this time to ensure safety.

[0033] Working principle: A walking passage is formed by two groups of partitions 2. When a person passes by, the left and right positions are restricted, so that when walking, the person must pass through the detection range of the distance sensor 5. The distance sensor 5 can identify the height of the person relatively quickly. The distance sensor 5 is a common technology on the market, and is commonly found in various devices that automatically detect height and weight. The slide bar 8 can slide up and down along the slide groove on the rear wall of the slide rail 12. The control device controls the extension length of the extension axis of the electric push rod 9 according to the height information of the person detected by the distance sensor 5 until the display screen 10 is aligned with the head of the person. Compared with the previous adjustment of the pitch angle to adapt to the form of the face, the recognition speed is faster and more accurate. A signal connection is formed between the two groups of photoelectric sensors 15. The signal is cut off when a person passes, so that the control device controls the electric push rod 9 not to extend at this time to ensure safety.
