Description

Technical Field

[0001] The utility model relates to the technical field of gate machines, in particular to a channel gate machine with a face recognition function. Background Art

[0002] A turnstile is a channel blocking device. Its most basic function is to allow only one person to pass through at a time. It is mainly used to manage the flow of people and regulate the entry and exit of pedestrians. It can be used at various entrances and exits that restrict outsiders from entering and exiting at will, such as subway turnstiles, airport turnstiles, etc.

[0003] Most of the gates currently in use use a face recognition verification system to control the door opening and closing system. However, for places with high security requirements, such as trains, subways, high-speed railways or airports, after verifying the passenger information, it is usually necessary to pass the security inspection equipment for security inspection. Installing two devices at the same time takes up a large area, and there are differences in the heights of different passengers. The face recognition module cannot quickly read the facial information, resulting in a long time for the passenger to enter the venue and inconvenient use. For example, Chinese Patent No.: ZL202121296644.1 A subway security gate includes a fixed frame and a hinge block. An asynchronous motor is installed at the upper end of the fixed frame, a threaded rod is connected to the lower end of the asynchronous motor, a bearing block is provided at the lower end of the threaded rod, a sleeve is provided on the outer sleeve of the threaded rod, a baffle is provided on one side of the sleeve, a placement groove is opened in the middle of the baffle, and a positioning hole is provided on the outer surface of the placement groove. An anti-collision strip is installed at one end of the baffle, and springs are provided on the upper and lower sides of the anti-collision strip. The fine corners inside the plate body can be cleaned to ensure the neat appearance of the equipment.

[0004] However, this device only has the function of allowing passengers to pass. After the passengers pass, they need to undergo security checks. The gate machine and security inspection equipment need to be installed at the entrance of the gate at the same time, which occupies a large area. In addition, in this solution, the face recognition module requires manual rotation of the hinge block to adjust the angle of the face recognition module, which is inconvenient to use and takes a long time to verify and pass. Summary of the invention

[0005] The technical problems to be solved by the present invention are how to improve the efficiency of security checks while regulating the passage of pedestrians, and how to facilitate the passage of pedestrians of different heights. The purpose of the present invention is to provide a facial recognition channel gate that can perform full-body security checks on passengers while verifying passenger information through facial recognition, and can also detect the height of pedestrians and automatically adjust the angle of the facial recognition module, thereby improving the efficiency of pedestrian entry.

[0006] The technical scheme adopted by the utility model is: a face recognition channel gate, including a gate, which is composed of a base and side panels, two side panels are provided and are respectively arranged on both sides of the top of the base, and also include a security door and a face recognition mechanism, the security door includes two detection plates arranged oppositely, a security door main box is provided on the top between the two detection plates, a controller is installed in the security door main box, the two detection plates are respectively arranged on opposite sides of the middle of the two side panels, a face recognition mechanism is provided on the top of one end of one side panel, a ticket verification module is provided on the top of the other end, and an alarm indicator light is installed on the top of the other side panel at the same end as the face recognition mechanism; a mounting tube is provided on the top of the side panel, and the face recognition mechanism is installed on the side panel through the mounting tube; the face recognition mechanism includes an angle adjustment mechanism and a face recognition module, the angle adjustment mechanism includes a worm and a fan gear, the worm and the fan gear are meshed with each other, and the worm is arranged in the mounting tube.

[0007] The face recognition channel gate provided by the utility model can achieve the following beneficial effects:

[0008] (1) By combining the gate with the security gate, security checks can be carried out while verifying pedestrian information. Pedestrians do not have to pass through multiple restrictive facilities one after another, which greatly speeds up the passage of pedestrians. At the same time, it reduces the footprint of the equipment and enables more facial recognition gates to realize a multi-channel security inspection system, making it easier to cope with large-scale pedestrian flow during peak hours and improving pedestrian passage efficiency.

[0009] (2) The angle adjustment mechanism can ensure that the facial recognition module can accurately collect facial information of pedestrians of different heights, thereby speeding up the recognition process and preventing the problem of time-consuming verification and passage due to inconvenience in facial recognition caused by differences in pedestrian heights.

[0010] Preferably, a pedal is provided on the base below the security door, and a pressure sensor is provided between the pedal and the base.

[0011] When a pedestrian stands on the pedal, the pedal presses the pressure sensor, and the pressure sensor generates an electrical signal to prompt that there is a pedestrian standing under the security door.

[0012] Preferably, a front swing gate and a rear swing gate with double doors are provided on the side panels at the front and rear ends of the pedal, the front swing gate is located on the side close to the face recognition mechanism, and the rear swing gate is located on the side close to the ticket verification module, and both the front swing gate and the rear swing gate are connected to the gate control mechanism shaft.

[0013] The front swing gate is used to restrict pedestrians from directly passing through the gate, so that the facial recognition mechanism has enough time to extract the facial information of pedestrians. The rear swing gate is used to restrict pedestrians from following in from behind. When pedestrians stand on the pedal, both the front and rear swing gates are closed, and the detection plate begins a security check. At the same time, the facial recognition mechanism compares the facial information of the pedestrian. After the facial recognition of the security inspection machine is completed, the rear swing gate opens, so that the front swing gate opens after the pedestrian walks out of the gate after the information is verified, and it is convenient for pedestrians from behind to enter the gate in turn.

[0014] Preferably, a pair of import safety gratings are installed on the side wall between the two side panels between the security door and the rear swing gate; a pair of export safety gratings are installed on the side wall of the side panel away from the import safety grating and one end of the front swing gate.

[0015] The entrance safety grating and exit safety grating are used to detect the position of the pedestrian being detected. When the pedestrian completely passes through the entrance safety grating and the pedestrian completely passes through the exit safety grating after the detection is completed, the rear swing gate and the front swing gate will be closed successively to prevent the rear swing gate from injuring the pedestrian.

[0016] Preferably, a distance sensor is provided at the bottom of the main box of the security door.

[0017] The distance sensor at the bottom of the main chassis can detect the height of pedestrians inside the security gate, so that the angle adjustment mechanism can be adjusted according to the height data of the pedestrians so that the face recognition module can be aimed at the face of the pedestrians, thereby facilitating accurate and rapid extraction of the facial information of the detected pedestrians and accelerating the efficiency of face recognition.

[0018] Preferably, two groups of infrared detectors arranged opposite to each other are provided on the two detection boards, and a group of infrared detectors on each detection board includes two infrared detectors of different heights.

[0019] Two infrared detectors at different heights are used to monitor the position of the monitored pedestrian. Face recognition will only begin when at least one team of infrared detectors at different heights is blocked. Otherwise, the alarm indicator light will prompt the correct position to ensure that the pedestrian is standing facing the face recognition module.

[0020] Preferably, the virtual central axis of the worm is meshed with the virtual central axis of the mounting tube, the fan gear is arranged on the back of the face recognition module, the axis of the fan gear is hinged to the outer side of the mounting tube, the fan gear is meshed with the spiral teeth on the surface of the worm, and the bottom of the worm is connected to the motor shaft located inside the side panel.

[0021] The motor drives the worm to rotate, and the worm drives the sector gear to rotate a certain angle, so that the sector gear rotates around its axis, so that the face recognition module can change its angle so as to aim at the faces of pedestrians of different heights.

[0022] Preferably, the face recognition module comprises a camera, a fill light, a focus sensor and a display screen, and the camera, the fill light and the focus sensor are located above the display screen.

[0023] The camera is used to extract the facial information of pedestrians, the fill light is used to take care of the pedestrian's face in low light conditions, the focus sensor is used to measure the position of the pedestrian's face so that the camera can extract clearer facial image information, and the display screen is used to display facial video information, making it easier for pedestrians to autonomously align themselves with the camera for quick face recognition verification.

[0024] Preferably, a light shield is provided on the top of the camera.

[0025] The lens hood can block the strong light near the camera, prevent non-imaging light from directly entering the lens, and reduce glare and ghosting caused by direct sunlight or strong light reflection. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following is further described in conjunction with specific embodiments. Figure 1-6As shown, this embodiment is a face recognition channel gate, including a gate 1, which is composed of a base 12 and a side panel 13.

An alarm indicator light 211 is installed on the top of the other side panel 13 at the same end as the face recognition mechanism 3; a mounting tube 31 is provided on the top of the side panel 13, and the face recognition mechanism 3 is installed on the side panel 13 through the mounting tube 31; the face recognition The mechanism 3 includes an angle adjustment mechanism 32 and a face recognition module 33. The angle adjustment mechanism 32 includes a worm 321 and a sector gear 322. The worm 321 and the sector gear 322 are meshed with each other. The worm 321 is arranged in the installation tube 31. By combining the gate 1 with the security door 2, a security check can be performed while verifying the pedestrian information. Pedestrians do not need to pass through multiple restriction facilities in succession, which greatly speeds up the pedestrian passage speed. At the same time, the equipment footprint is reduced, and more face recognition channel gates can be installed at the same time to form a multi-channel security inspection system, which is convenient for coping with large-scale traffic during peak hours and improves the pedestrian passage efficiency. By adopting the angle adjustment mechanism 32, it can be ensured that the face recognition module 33 accurately collects the facial information of pedestrians of different heights, speeds up the recognition speed, and prevents the problem of inconvenience in facial recognition due to differences in pedestrian heights, resulting in a long verification and passage time.

[0038] Reference Figure 4 As shown, in this embodiment, a pedal 111 is provided on the base 12 below the security door 2, and a pressure sensor 112 is provided between the pedal 111 and the base 12. When a pedestrian stands on the pedal 111, the pedal 111 presses the pressure sensor 112, and the pressure sensor 112 generates an electrical signal to prompt that there is a pedestrian standing below the security door 2.

[0039] Reference Figure 1 and Figure 4As shown, in the present embodiment, a front swing gate 131 and a rear swing gate 132 with double doors are provided on the side panels 13 located at the front and rear ends of the pedal 111, the front swing gate 131 is located on the side close to the face recognition mechanism 3, and the rear swing gate 132 is located on the side close to the ticket verification module, the front swing gate 131 and the rear swing gate 132 are both connected to the gate control mechanism, the front swing gate 131 restricts pedestrians from directly passing through the gate 1, so that the face recognition mechanism 3 has enough time to extract the facial information of the pedestrian, and the rear swing gate 132 is used to restrict the pedestrians from following in; when the pedestrian stands on the pedal 111, the front swing gate 131 and the rear swing gate 132 are closed at the same time, the detection plate 21 starts to perform a safety check, and the face recognition mechanism 3 compares the facial information of the pedestrian. After the safety check and face recognition are completed, the rear swing gate 132 and the front swing gate 131 are opened successively, so that the pedestrians can walk out of the gate 1 after the information is verified, and it is convenient for the pedestrians from the rear to enter the gate 1 in sequence.

[0040] Reference Figure 1 or Figure 4 As shown, in this embodiment, a pair of import safety gratings 14 are installed on the side wall between the two side panels 13 between the security door 2 and the rear swing gate 132; a pair of exit safety gratings 15 are installed on the side wall of the side panel 13 away from the import safety grating 14 and the front swing gate 131. The import safety grating 14 and the exit safety grating 15 are used to detect the position of the pedestrian being detected. After the detection is completed, when the pedestrian completely passes through the exit safety grating 15, the rear swing gate 132 is closed. After the next pedestrian behind completely passes through the import safety grating 14, the front swing gate 131 is closed to prevent the front swing gate 131 or the rear swing gate 132 from pinching or injuring the pedestrian.

[0041] Reference Figure 2 As shown, in this embodiment, a distance sensor 222 is provided at the bottom of the main box 22 of the security inspection door. The distance sensor 222 at the bottom of the main box can detect the height of pedestrians inside the security inspection door 2, so that the angle adjustment mechanism 32 can be adjusted according to the height data of the pedestrian so that the face recognition module 33 can be aligned with the face of the pedestrian, so as to accurately and quickly extract the facial information of the detected pedestrian and speed up the efficiency of face recognition.

[0042] Reference Figure 4As shown, in this embodiment, two groups of infrared detectors 23 are arranged opposite to each other on the two detection plates 21, and a group of infrared detectors 23 on each detection plate 21 includes two infrared detectors 23 of different heights. The two infrared detectors 23 of different heights are used to monitor the position of the monitored pedestrians. When at least one pair of infrared detectors 23 at different heights is blocked, face recognition is started, otherwise the alarm indicator light 211 will prompt the correct standing position, so as to ensure that the pedestrian's standing position is facing the face recognition module 33. The infrared detectors 23 of different heights are used to detect pedestrians of different heights. When at least the infrared detector of the same height is blocked by a pedestrian, it is determined that there is someone in the monitoring area, so as to facilitate the security inspection of the security gate 2 and the face recognition mechanism 3 to perform face recognition verification.

The worm 321 is driven to rotate by the motor, and the worm 321 drives the fan gear 322 to rotate a certain angle, so that the fan gear 322 rotates around its axis, so that the face recognition module 33 can change its angle so as to align with the faces of pedestrians of different heights.

[0044] Reference Figure 5 As shown, in this embodiment, the face recognition module 33 includes a camera 331, a fill light 332, a focus sensor 333 and a display screen 335. The camera 331, the fill light 332 and the focus sensor 333 are located above the display screen 335. The camera 331 is used to extract facial information of pedestrians, the fill light 332 is used to take care of the faces of pedestrians in insufficient light conditions, the focus sensor 333 is used to measure the position of the faces of pedestrians so that the camera 331 can extract clearer facial image information, and the display screen 335 is used to display facial video information, so that pedestrians can autonomously align themselves with the camera 331 for rapid face recognition verification.

[0045] Reference Figure 5 As shown in the figure, in this embodiment, a sunshade 334 is provided on the top of the camera 331. The sunshade 334 can block the strong light near the camera 331, prevent non-imaging light from directly entering the lens, and reduce the glare and halo caused by direct sunlight or strong light reflection.

[0046] Example 2

[0047] When using the utility model, the pedestrian first verifies the ticket verification mechanism, then enters the gate machine 1 through the swing gate, and after passing the inlet safety gratings 14 arranged in pairs on the two side plates 13, the front swing gate 131 and the rear swing gate 132 are closed. The front swing gate 131 is used to temporarily restrict the pedestrian from continuing to move forward to facilitate face recognition, and the rear swing gate 132 is used to restrict the pedestrians from following in, so that only one person can pass through at a time; when the pedestrian stands on the pedal 111 at the upper end of the bottom of the gate machine 1, the pressure sensor 112 under the pedal 111 detects the pedestrian, and then the distance sensor 222 is used to detect the distance between the distance sensor 222 and the top of the pedestrian's head, so as to judge the pedestrian's face. The height of the head is then adjusted by adjusting the angle adjustment device so that the camera 331 on the face recognition module 33 can face the pedestrian's face, the distance of the pedestrian's face is accurately measured by the focus sensor 333, and the focus of the camera 331 is adjusted so that the face recognition module 33 can accurately and clearly extract the pedestrian's facial information and compare it with the facial information in the database. At the same time, the coils in the two detection plates 21 of the security door 2 emit electromagnetic waves to detect whether the hidden metal objects on the pedestrian are prohibited items. If they are prohibited items, the alarm indicator light 211 lights up to remind the security personnel to conduct manual inspection. If they are not prohibited items, face recognition verification is performed;

[0048] After the face recognition verification is successful, the controller 221 controls the gate control mechanism to open the front swing gate 131, so that the verified pedestrian can continue to pass through the gate 1. When the successfully verified pedestrian walks out of the gate 1 and passes the exit safety grating 15, the front swing gate 131 is closed to prevent the front swing gate 131 from closing and injuring the pedestrian. At the same time, the rear swing gate 132 is opened, and the next unverified pedestrian continues to enter the gate 1 through the opened rear swing gate 132. After the pedestrian passes through the entrance safety grating 14, the rear swing gate 132 is closed to prevent pedestrians from following in.

[0049] Example 3

[0050] When the height of a pedestrian is significantly different from the average height of an ordinary adult, the distance sensor 222 detects the height of the pedestrian, and the controller 221 controls the angle adjustment mechanism 32 in the face recognition mechanism 3 to make adjustments, that is, the motor drives the worm 321 to rotate, the worm 321 drives the fan gear 322 to rotate, and the fan gear 322 rotates around its axis, so that the face recognition module 33 connected to the fan gear 322 changes the elevation angle, so that the camera 331 on the face recognition module 33 can be aimed at the face of the pedestrian with a large height difference, avoiding the problem that the face recognition module 33 cannot immediately collect facial information due to height difference and delays the passage of pedestrians. At the same time, the face recognition module 33 is provided with a fill light 332, a focus sensor 333 and a light hood 334. The fill light 332 can provide fill light for the pedestrian's face when the lighting conditions are poor. The focus sensor 333 is used to help the camera 331 identify the facial features of the pedestrian. The light hood 334 is used to block the strong light near the camera 331, which can facilitate the camera 331 to collect clearer face recognition images.
