[0002] The camera is a liveness recognition terminal used in liveness recognition technology. It is usually fixed at a high place for use. By connecting the camera to an external computer through a data cable, the liveness in the monitored area can be recognized and processed. The lens of a traditional camera is prone to dust after long-term use, resulting in blurred monitored images and affecting the accuracy of liveness recognition. However, the camera is usually installed at a high place for use, which requires maintenance personnel to frequently climb to a high place for cleaning and maintenance. This not only increases the cleaning work of the maintenance personnel, but also makes it easy for the maintenance personnel to fall and get injured when they frequently climb to a high place for work, which brings great inconvenience to the maintenance personnel. In response to the above problems, we have designed a liveness recognition terminal. Summary of the invention

[0003] The purpose of the present invention is to provide a living body recognition terminal for solving the problems existing in the background technology.

DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1-4 As shown, a living body recognition terminal of the present invention comprises a mounting plate 1, a camera 2 and two symmetrically arranged C-shaped slide rails 201 are arranged at the front end of the mounting plate 1, the two C-shaped slide rails 201 are located above the camera 2, and the two C-shaped slide rails 201 are inclined from back to front and from top to bottom, a top plate 21 is arranged at the upper end of the two C-shaped slide rails 201, a first electromagnetic telescopic valve 22 and a second electromagnetic telescopic valve 23 are arranged side by side in the middle of the top plate 21, and the output ends of the two electromagnetic telescopic valves are both arranged to penetrate the top plate 21 downward;

[0024] A plurality of transparent protective films 3 are bonded to the front end of the camera 2, and the upper end of each transparent protective film 3 is connected to a counterweight part 32 through an elastic connecting part 31. The distance between the output end of the first electromagnetic telescopic valve 22 and the output end of the second electromagnetic telescopic valve 23 is 1-1.5 times the width of the counterweight part 32. Several counterweight parts 32 are slidably connected to two C-shaped slide rails 201.

[0025] A controller 5 is disposed at the front end of the mounting plate 1 , and the first electromagnetic telescopic valve 22 and the second electromagnetic telescopic valve 23 are both electrically connected to the controller 5 .

[0026] In the initial state, the output ends of the first electromagnetic telescopic valve 22 and the second electromagnetic telescopic valve 23 are both in an extended state, and the plurality of counterweights 32 are all located at the rear side of the output end of the second electromagnetic telescopic valve 23. Since the two C-shaped slide rails 201 are both inclined from back to front and from top to bottom, the plurality of counterweights 32 will abut against each other under the action of gravity, and the frontmost counterweight 32 will abut against the rear end of the output end of the second electromagnetic telescopic valve 23.

[0027] When in use, the entire terminal is placed at a high place through the mounting plate 1, and then the camera 2 and the controller 5 are connected to the external computer through a data cable. After the connection is completed, the camera 2 can monitor and identify the area it is pointing to. Since a multi-layer transparent protective film 3 is bonded to the front end of the lens of the camera 2, dust will adhere to the outermost transparent protective film 3 during long-term use of the camera 2. If the bonded dust affects the quality of the monitoring image, the user can send a film peeling instruction to the controller 5 through the external computer. After receiving the film peeling instruction, the controller 5 controls the second electromagnetic telescopic valve 23 to be energized and work for 5 seconds, so that the second electromagnetic telescopic valve 23 drives its output end to retract. During this period, a number of counterweights 32 will slide forward under the action of gravity until the frontmost counterweight 32 abuts against the rear end of the output end of the first electromagnetic telescopic valve 22. Since the spacing between the output end of the first electromagnetic telescopic valve 22 and the output end of the second electromagnetic telescopic valve 23 is 1-1.5 times the width of the counterweight 32, Only the frontmost counterweight part 32 will be accommodated between the two output ends. After the second electromagnetic telescopic valve 23 is powered off, its output end will extend to block the second counterweight part 32. After the second electromagnetic telescopic valve 23 is powered off, the controller 5 will control the first electromagnetic telescopic valve 22 to be powered on for 5 seconds, so that the first electromagnetic telescopic valve 22 drives its output end to retract. At this time, the counterweight part 32 between the two output ends will slide forward out of the two C-shaped slide rails 201 under the action of gravity. After the counterweight part 32 is separated from the two C-shaped slide rails 201, the front transparent protective film 3 will be peeled off forward through the elastic connecting part 31 connected thereto. In this way, the transparent protective film 3 with dust on it is removed, so that the monitoring screen can be restored to a clear state. The multi-layer transparent protective film 3 can extend the maintenance cycle of the camera 2 lens, so that the maintenance personnel do not need to frequently climb to a high place to clean and maintain the camera 2, which reduces the labor intensity of the maintenance personnel to a certain extent, and the maintenance personnel are not easy to fall and get injured, which brings great convenience to the maintenance personnel.

[0028] The front end of the mounting plate 1 is fixedly connected to two supports 4 distributed on the left and right, the front ends of the two C-shaped slide rails 201 are respectively hinged to the front ends of the two supports 4, the rear ends of the two C-shaped slide rails 201 are fixedly connected to a connecting plate 41, the middle part of the connecting plate 41 is threadedly connected to a screw rod 42 that is arranged to penetrate from top to bottom, the lower end of the screw rod 42 is rotatably connected to a connecting column 421, the lower end of the connecting column 421 is hinged to a T-shaped slider 43, the upper end of the camera 2 is provided with a T-shaped slide rail 44, the T-shaped slider 43 is slidably connected to the T-shaped slide rail 44, and the upper end of the screw rod 42 is provided with a handle 45;

[0029] The two supports 4 are used to support the front ends of the two C-shaped slide rails 201. The connecting plate 41 cooperates with the screw rod 42, the T-shaped slider 43 and the T-shaped slide rail 44 to support the rear ends of the two C-shaped slide rails 201. When the user turns the handle 45, the handle 45 can drive the screw rod 42 to rotate. Since the screw rod 42 is rotatably connected to the connecting column 421 and is threadedly connected to the connecting plate 41, the screw rod 42 can drive the connecting plate 41 to move up and down according to the rotation direction. Since the front ends of the two C-shaped slide rails 201 are respectively connected to the connecting column 421, the connecting column 421 is connected to the connecting column 41. The front ends of the two supports 4 are hinged, so the up and down movement of the connecting plate 41 will drive the two C-shaped slide rails 201 to flip up and down, so that the inclination angle of the two C-shaped slide rails 201 can be changed. The connection column 421 and the T-shaped slider 43 are hinged to allow the screw rod 42 to adapt to the inclination angle of the connecting plate 41. The T-shaped slider 43 and the T-shaped slide rail 44 are slidably connected to keep the lower end of the screw rod 42 connected to the upper end of the camera 2, and also to allow the screw rod 42 to adapt to the position of the C-shaped slide rail 201 after rotation;

[0030] After the transparent protective film 3 at the front end of the camera 2 is peeled off, the maintenance personnel can control the output ends of the first electromagnetic telescopic valve 22 and the second electromagnetic telescopic valve 23 to remain in a contracted state when sticking a new transparent protective film 3, and then adjust the two C-shaped slide rails 201 to an inclined state from back to front and bottom to top. In this way, when the user assembles the counterweight part 32 on the two C-shaped slide rails 201, the counterweight part 32 can automatically slide to the rear side of the two C-shaped slide rails 201 under the action of gravity, which makes it convenient for the maintenance personnel to perform maintenance operations.

[0031] A pressure sensor 501 is embedded on the rear side of the output end of the second electromagnetic telescopic valve 23. The pressure sensor 501 is electrically connected to the controller 5. Under normal conditions, a number of counterweights 32 will abut against the pressure sensor 501 under the action of gravity. The pressure sensor 501 can detect the corresponding pressure value and transmit the pressure value to an external computer through the controller 5 for observation by the staff. The staff can determine the amount of remaining transparent protective film 3 based on the pressure value. If the pressure sensor 501 is at 0 value for a long time, the external computer can remind the staff that the camera 2 needs to be glued with a new transparent protective film. Such a design can make the entire terminal more intelligent and convenient for the staff to manage and use.

[0032] The lower ends of several layers of transparent protective films 3 are fixedly connected to the mounting plate 1 through flexible fixing parts 51, and a round rod 52 extending forward is provided on the lower side of the front end of the mounting plate 1, and the flexible fixing part 51 is sleeved on the outside of the round rod 52 through a circular groove 521, and a limiting nut 53 is threadedly connected to the front end of the round rod 52, and a plurality of anti-slip grooves 54 are provided on the outside of the limiting nut 53. In this way, after the transparent protective film 3 is peeled off, it will be suspended on the lower side of the terminal through the flexible fixing part 51 instead of detaching from the entire terminal, thereby avoiding the transparent protective film 3 from falling off and causing unnecessary trouble. In addition, the flexible fixing part 51 cooperates with the elastic connecting part 31 to stabilize the transparent protective film 3, so that the transparent protective film 3 will not be peeled off during normal use. After the user unscrews the limiting nut 53, the flexible fixing part 51 can be removed from the round rod 52, and the anti-slip groove 54 can increase the friction between the limiting nut 53 and the hand, making it convenient for the user to twist the limiting nut 53.

[0033] The mounting plate 1 is provided with a plurality of countersunk holes 55, and the countersunk holes 55 can be equipped with bolts to fix the entire terminal to the wall.

[0034] The present invention provides a living body recognition terminal, wherein a plurality of layers of transparent protective films are bonded to the front end of a lens of the camera. When dust adheres to the transparent protective film and affects the clarity of a monitoring image, maintenance personnel can peel off the dust-adhered transparent protective film without climbing to a high place. In this way, the maintenance personnel do not need to frequently climb to a high place to clean and maintain the camera, thereby reducing the labor intensity of the maintenance personnel to a certain extent, and the maintenance personnel are less likely to fall and get injured, thereby bringing great convenience to the maintenance personnel.

[0035] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
