DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

An opening and closing mechanism 2 for controlling the opening and closing of the gate machine by face recognition is provided between the upper and lower inner walls of the two bodies 1. An alarm mechanism 3 for improving the alarm recognition effect of the gate machine is provided on the upper surface of the left body 1.

[0026] See also Figures 2 to 4 In order to realize the use of face recognition gate opening and closing machine, the opening and closing mechanism 2 in this embodiment includes two rotating shafts 21, two gates 22, explosion-proof box 23, face recognition module 24, explosion-proof high-transmittance glass 25 and driving member 26. The two rotating shafts 21 are respectively rotatably connected between the upper and lower inner walls of the two bodies 1 through bearings, the two gates 22 are respectively fixed to the outer sides of the two rotating shafts 21, the explosion-proof box 23 is fixed to the upper surface of the right body 1, and the face recognition module 24 is fixed to the inner wall of the explosion-proof box 23. When someone approaches the gate When the machine is turned on, the face recognition module 24 captures the face image through the explosion-proof high-transparency glass 25. The face recognition module 24 processes the captured image and extracts the face features. The explosion-proof high-transparency glass 25 is fixed to the inner wall of the explosion-proof box 23 and is located on the front of the face recognition module 24. The explosion-proof box 23 and the explosion-proof high-transparency glass 25 together provide a relatively stable and isolated environment for the face recognition module 24 to avoid damage. The driving member 26 is arranged at the bottom end of the two rotating shafts 21 to drive the two gates 22 to rotate and open and close.

[0027] The driving member 26 includes two extension shafts 261, two driven gears 262, two servo motors 263 and two driving gears 264. The two extension shafts 261 are respectively fixed to the bottom ends of the two rotating shafts 21, the two driven gears 262 are respectively fixed to the outer sides of the two extension shafts 261, the two servo motors 263 are respectively fixed to the inner bottom walls of the two machine bodies 1, the two driving gears 264 are respectively fixed to the outer sides of the output shafts of the two servo motors 263, and the two driving gears 264 are respectively meshed and connected with the two driven gears 262. The gate opening signal sent by the controller activates the servo motor 263, the servo motor 263 drives the driving gear 264 to rotate, and the driving gear 264 meshes with the driven gear 262, thereby driving the extension shaft 261 to rotate, and the rotation of the extension shaft 261 is transmitted through the rotating shaft 21, driving the gate 22 to rotate.

[0028] In this embodiment, the bottom ends of the two extension shafts 261 are rotatably connected to the inner bottom walls of the two bodies 1 through bearings, respectively. The driving gear 264 and the driven gear 262 are both bevel gears. A controller is fixed to the inner wall of the right body 1. The face recognition module 24 compares the extracted facial features with the facial data stored in the database. If the comparison is successful, that is, the person is identified as an authorized person, the controller will send a gate opening signal. If the comparison fails, that is, the person is identified as an unauthorized or blacklisted person, the controller will not send a gate opening signal, and the alarm mechanism 3 will be triggered at the same time. Limit plates 27 are fixed on the opposite sides of the two bodies 1, and the two limit plates 27 are respectively located in front of the two gates 22. The gate 22 is opened or closed under the drive of the rotating shaft 21 to allow or prohibit people from passing. After the authorized person passes through the gate 22, the gate 22 is closed under the action of the driving member 26 to prepare for the next identification and passage, and the limit plates 27 can keep the gate 22 facing horizontal after being reset.

[0029] See also Figure 5 In order to improve the alarm recognition function of the gate machine, the alarm mechanism 3 in this embodiment includes a connecting frame 31, an infrared camera probe 32, an alarm 33, two alarm modules 34, four protective plates 35 and a plurality of pressure sensors 36. When the face recognition gate machine is in working state, various sensors and modules of the alarm mechanism 3 are in standby state, ready to monitor any abnormal situation. The connecting frame 31 is fixed to the upper surface of the left body 1, the infrared camera probe 32 is fixed to the outer side of the connecting frame 31, the alarm 33 is fixed to the upper surface of the connecting frame 31, the two alarm modules 34 are respectively fixed to the inner walls of the two bodies 1, the four protective plates 35 are respectively fixed to the front and rear sides of the two gates 22, and the plurality of pressure sensors 36 are respectively fixed between the side opposite to the protective plate 35 and the gate 22. The plurality of pressure sensors 36 are respectively installed on the side opposite to the protective plate 35 and the gate 22 to monitor whether there is illegal thrust or impact on the gate 22.

[0030] In this embodiment, the number of infrared camera probes 32 is not less than two, and they are arranged in a circular array on the outside of the connecting frame 31. The infrared camera probes 32 are distributed in a circular array on the outside of the connecting frame 31, and multiple probes are used to detect the environment at different angles. The combination of multiple probes achieves the purpose of 360-degree monitoring to monitor the environment around the gate to detect the approach or abnormal behavior of unauthorized personnel. The alarm module 34 is electrically connected to the wireless module, and several pressure sensors 36 are electrically connected to the alarm module 34 through wires. When the pressure sensor 36 or the infrared camera probe 32 detects an abnormal situation, or the face recognition module 24 fails to compare, the alarm module 34 is activated, and the alarm 33 sounds an alarm to warn on-site personnel and the security control center that an abnormal situation has occurred, and the alarm module 34 transmits the alarm information to the security control center or the mobile device of the manager through an electrical connection or a wireless module.

[0031] The working principle of the above embodiment is:

[0032] (1) When implementing the use of face recognition gate opening and closing machine, when someone approaches the gate machine, the face recognition module 24 captures the face image through the explosion-proof high-transparency glass 25. The face recognition module 24 processes the captured image and extracts the face features. At the same time, the explosion-proof box 23 and the explosion-proof high-transparency glass 25 together provide a relatively stable and isolated environment for the face recognition module 24 to avoid damage. The face recognition module 24 compares the extracted face features with the face data stored in the database. If the comparison is successful, that is, the person is identified as an authorized person, the controller will send a gate opening signal. If the comparison fails, that is, the person is identified as an unauthorized person or a blacklisted person, the controller will send a gate opening signal. The controller does not send out a gate opening signal, and at the same time triggers the alarm mechanism 3. The gate opening signal sent by the controller activates the servo motor 263, and the servo motor 263 drives the driving gear 264 to rotate. The driving gear 264 meshes with the driven gear 262, thereby driving the extension shaft 261 to rotate. The rotation of the extension shaft 261 is transmitted through the rotating shaft 21, driving the gate 22 to rotate. The gate 22 is opened or closed under the drive of the rotating shaft 21, allowing or prohibiting people from passing. After the authorized person passes through the gate 22, the gate 22 is closed under the action of the driving member 26, preparing for the next identification and passage, and the limit plate 27 can keep the reset gate 22 in the opposite horizontal direction.

[0033] (2) When the gate is used to improve the alarm recognition function, when the face recognition gate is in operation, the various sensors and modules of the alarm mechanism 3 are in standby mode, ready to monitor any abnormal situation. A number of pressure sensors 36 are respectively installed on the side of the protective plate 35 opposite to the gate 22 to monitor whether there is any illegal thrust or impact on the gate 22. The infrared camera probes 32 are distributed in a circular array on the outside of the connecting frame 31, and multiple probes are used to detect the environment at different angles. The combination of multiple probes achieves the purpose of 360-degree monitoring to monitor the environment around the gate to detect the approach or abnormal behavior of unauthorized personnel. When the pressure sensor 36 or the infrared camera probe 32 detects an abnormal situation, or the face recognition module 24 fails to compare, the alarm module 34 is activated, and the siren 33 sounds an alarm to warn the on-site personnel and the security control center that an abnormal situation has occurred. The alarm module 34 transmits the alarm information to the security control center or the mobile device of the management personnel through an electrical connection or a wireless module.
