Example 3

The laboratory 3D face recognition simulation display method comprises the following steps:

the method comprises the following steps: during display, the reducing motor is started to rotate positively to drive the rotating rod 208 to rotate clockwise, the rotating shaft 206 is driven to rotate clockwise through the transmission mechanism 209, the diameter value of the driven wheel is twice of that of the driving wheel, the rotating shaft 206 is decelerated in the transmission process to reduce the rotating speed of the gear 207, the gear 207 and the rotating shaft 206 rotate synchronously when the rotating shaft 206 rotates clockwise, and the telescopic plate 203 is driven to extend upwards through the matching of the gear 207 and the rack 205;

step two: when the expansion plate 203 extends upwards, the angle value of an included angle between two second mounting rods 508 at the bottom of the mounting block 204 is reduced, the two second sliding sleeves 505 are driven to approach each other through the second mounting rods 508, when the two second sliding sleeves 505 approach each other, the sliding block 503 is pulled downwards through the first mounting rod 507, so that the two dustproof plates 304 are separated from each other by pulling the pull rope 307, the ascending process of the expansion plate 203 and the separation process of the dustproof plates 304 are synchronously performed, and the face recognition simulator 7 extends out of the main box body 1 through a gap between the two dustproof plates 304, so that simulation display is performed through the face recognition simulator 7;

step three: after the show ends, take in facial recognition simulator 7 inside the main tank body 1 and seal and deposit, start gear motor reversal, drive gear 207 anticlockwise rotation through bull stick 208 and drive mechanism 209, cooperation through gear 207 and rack 205 drives expansion plate 203 and retrieves downwards, contained angle value between two second installation poles 508 increases simultaneously, two second sliding sleeves 505 keep away from each other, under the reaction force of first spring 306, two slides 303 are close to each other, thereby after facial recognition simulator 7 shrink gets into main tank body 1 is inside, contact through two dust guards 304 and close opening 101, prevent that outside dust from getting into inside the main tank body 1.

When the face recognition simulator is used, the telescopic plate 203 is controlled to extend upwards or retract downwards through the forward and reverse rotation of the speed reducing motor, the telescopic plate 203 is extended during display, the face recognition simulator 7 is used for simulation display, the telescopic plate 203 is retracted after the display is finished, the face recognition simulator 7 is stored in a sealed mode, the face recognition simulator 7 is protected, when the telescopic plate 203 rises or falls, the two dustproof plates 304 are separated from or close to each other, the opening 101 is closed through the dustproof plates 304 after the face recognition simulator 7 is retracted into the main box body 1, and when dust is prevented from entering the main box body 1, the situation that an object above the main box body 1 falls down and enters the main box body 1 through the opening 101 to damage the face recognition simulator 7 can be prevented.
