Description

Technical Field

[0001] The utility model relates to the technical field of face recognition, in particular to a face recognition device for school buses. Background Art

[0002] Facial recognition technology includes several key steps, such as face detection, feature extraction and face comparison. In actual applications, users need to register first and input facial image information into the system, which will then extract features from it and save them. When the user authenticates again, the system will obtain the current facial image, extract features again, and compare them with the previously saved features to confirm the identity.

[0003] For the safety of students on their way to and from school, facial recognition can also be installed on school buses. Although drivers often meet students and are familiar with them, there are certain special circumstances, such as when the driver changes shifts and the replacement driver is not familiar with the students, or when the driver is threatened and allows someone he does not know to get on the bus.

[0004] Taking the above into consideration, a face recognition device and an interception device can be installed at the door of the school bus, similar to the security check of the subway. The difference is that the face recognition device identifies the students, and only after the recognition is passed, the interception device similar to the security check will be opened to let the students in. However, there are two difficulties in this design: First, the installation position of the face recognition device is difficult to determine, because students are in the stage of physical development, and the height difference between students of similar age may be large. The face recognition device cannot meet the needs of students of different heights at any height; second, the opening and closing of the interception device must rely on the power on the school bus to drive. If the school bus breaks down and the power cannot be started, the interception device installed at the door will become a burden, affecting students from getting off the school bus.

DETAILED DESCRIPTION

[0027] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation modes is used to help understand the present invention, but does not constitute a limitation to the present invention.

[0028] In addition, the technical features involved in each embodiment of the present invention described below can be combined with each other as long as there is no conflict between them.

[0029] In the idle space of this device, all electrical components and their matching drivers are placed, and all the driving parts mentioned below, which refer to power elements, electrical components and adapted power supplies, are connected through wires by personnel in this field. The specific connection means should refer to the following description, and the electrical connection is completed in the working order of each electrical component. The detailed connection means are well known in the art.

[0030] The face recognition device for school buses provided in this specific embodiment is as follows: Figure 1 and Figure 2 As shown, it includes interception components and identification components, among which:

[0031] The interception component includes a side gate 1 and a side gate 2 installed on both sides of the vehicle door. The side gate 2 is connected to a shaft 3 through a bearing. The shaft 3 is provided with a railing 4 on the back of the side gate 2. The two can be separated manually. In addition, a driving mechanism 5 for driving the shaft 3 to rotate is provided in the side gate 2. Figure 4 As shown, the driving mechanism 5 includes a mounting plate 501 connected inside the side gate 2, a servo motor 502 is connected to the mounting plate 501, and the output shaft of the servo motor 502 and the outer peripheral side of the shaft 3 are fixedly sleeved with mutually meshing gears 503.

[0032] In this way, the servo motor 502 can drive the shaft rod 3 and the railing 4 to open under the drive of the two gears 503 to allow the students to pass.

[0033] In addition, the reason why the shaft rod 3 and the railing 4 can be separated is specifically, as Figure 5 As shown, a plug hole 11 is provided on one end of the shaft rod 3 facing the railing 4, and a plug rod 12 is inserted into the plug hole 11. The plug rod 12 is fixed to the back of the railing 4. At the same time, a clamping mechanism 13 is provided between the plug rod 12 and the shaft rod 3 to clamp the two. Figure 6 As shown, the engaging mechanism 13 includes a cross slot 1301 which is jointly opened between the plug rod 12 and the railing 4. The cross slot 1301 passes through the railing 4 and stays at a position close to the front of the plug rod 12. At the same time, it also includes a cross slot 1302 which is opened at the end of the shaft rod 3 at the position corresponding to the insertion hole 11 and corresponds to the cross slot 1301. A cross plate 1303 is connected between the two. In addition, the outer side of the cross plate 1303 protrudes to the back of the railing 4, and a collar 14 is engaged and sleeved on the protruding part. The collar 14 is a metal ring. In addition, a magnetic ring is installed at the position corresponding to the metal ring on the back of the railing 4. The magnetic ring is connected to the power system wires of the school bus through a wire.

[0034] Thus, the engaging mechanism 13 is a cross slot structure and a cross plate 1303 structure. This structure can be manually removed to open the railing 4 when the power is off, so as to prevent the problem that the railing 4 cannot be opened when the school bus fails and the power is not connected, which affects the students' departure. Secondly, the ring 14 and the magnetic ring on the back of the railing 4 produce an adsorption effect through electromagnetic induction when the power is smooth, so as to further fix the cross plate 1303. When the school bus fails and the power system does not work, this magnetic adsorption effect will disappear, and the cross plate 1303 can still be manually removed, without adding extra operations to delay time.

[0035] Specifically speaking of this principle, when current passes through a magnetic coil, according to Ampere's law, a magnetic field is generated around the magnetic coil. If ferromagnetic materials are placed around the magnetic coil, these materials will be magnetized by the magnetic field and acted upon by magnetic force. The magnetic domains in the ferromagnetic material will be rearranged so as to be consistent with the direction of the magnetic field generated by the magnetic coil, thereby being attracted to the magnetic coil. When the power supply is disconnected, the current disappears, the magnetic field disappears, and the ferromagnetic material will fall off. Substituted into the present application, the ferromagnetic material referred to is the metal collar 14.

[0036] The recognition component includes an installation box 6 connected to the front of the side gate 1, a vertical plate 7 is fixed on the top of the installation box 6, a longitudinal slide 8 is provided on the outer side of the vertical plate 7, and the front side thereof is slidably connected to the face recognition device 9 through the slide 8. In addition, a sliding mechanism 10 for driving the face recognition device 9 to move up and down along the slide 8 is provided between the installation box 6 and the vertical plate 7. Figure 3As shown, the sliding mechanism 10 includes a bearing seat 1001 installed inside the installation box 6 and a through hole 1002 opened at the top thereof corresponding to the upper and lower sides of the bearing seat 1001. The bearing seat 1001 is cooperated with a screw rod 1003 that passes through the through hole 1002 and extends into the slide groove 8. The screw rod 1003 is threadedly connected with a slider 1004 located in the slide groove 8. The slider 1004 is fixed to the back of the face recognition device 9. In addition, the installation box 6 is also provided with a rotating mechanism 1005 for driving the screw rod 1003 to rotate. The rotating mechanism 1005 includes a motor 100501 installed in the installation box 6. The output shaft of the motor 100501 and the outer peripheral side of the screw rod 1003 are fixedly sleeved with a sprocket 100502 located in the installation box 6 and in the same horizontal direction. A tensioned chain 100503 is cooperated with the two sprockets 100502. Driven by the rotating mechanism 1005, the slider 1004, which is restricted from rotating, will drive the face recognition device 9 to slide up and down along the slide slot 8 when the screw rod 1003 rotates. Therefore, the position of the face recognition device 9 can be adjusted according to the height of the students, so that students of different heights can perform face recognition at a suitable position. Such a structural design is more practical and fits the actual situation.

[0037] In addition, for the through hole 1002 mentioned above, in order to avoid structural interference, the diameter of the through hole 1002 needs to be larger than the diameter of the screw rod 1003, so that the screw rod 1003 does not contact it when passing through it. In addition, since the screw rod 1002 is only connected at the bottom through the bearing seat 1001, it may not be very stable. Therefore, an additional combined bearing can be installed in the through hole 1002, and the outer ring of the combined bearing is fixedly connected to the inner wall of the through hole 1002, and its inner ring is inserted through the screw rod 1003 after interference fit, so as to further stabilize the screw rod 1002.
