Obviously, the specific details described below are only some embodiments of the present invention, and the present invention can also be implemented in many other embodiments different from those described herein. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0035] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be understood as limiting the present invention. The following describes various embodiments of the present invention in detail with reference to the accompanying drawings.

[0036] Example 1

[0037] See also Figures 1 to 14 The present invention preferably provides a technical solution: a channel gate device with a facial recognition function, comprising: a mounting plate 1, a telescopic electric door structure 2 arranged on one side of the mounting plate 1, and the telescopic electric door structure 2 can be horizontally limited and telescopically moved; and a multi-channel gate mechanism for facial recognition of the crowd; it also includes a connecting member 3, which is connected as a combination of the telescopic electric door structure 2 and the multi-channel gate mechanism to form a channel gate; the multi-channel gate mechanism includes a plurality of base plates 5, the upper surface of each base plate 5 is provided with a facial recognition gate seat for a single person to pass through, and the entry and exit directions of adjacent facial recognition gate seats are opposite; and a connecting rod transmission assembly is arranged between adjacent base plates 5, and the connecting rod transmission assembly is used to drive the multi-channel gate mechanism to switch its form. When the multi-channel gate mechanism expands into a linear distribution and acts with the telescopic electric door structure 2, it is used for the sequential passage of people with dense traffic; when it contracts into a polygonal form and acts with the telescopic electric door structure 2, it is used for the passage of large-volume goods or vehicles.

[0038] In this embodiment, the telescopic electric door structure 2 and the multi-channel gate mechanism can be connected together to form a channel gate through the connection member 3, where the end of the mounting plate 1 is fixed to the wall, such as Figure 1-6 As shown, this gate is suitable for a variety of places, such as factories, schools, companies and other places where facial recognition is required for entry and exit;

[0039] The multi-channel gate mechanism includes a plurality of base plates 5, each of which is provided with a facial recognition gate seat on its upper surface. The plurality of facial recognition gate seats facilitates the simultaneous entry and exit of a large number of people, while each facial recognition gate seat can limit the passage of a single person, thereby avoiding adverse effects such as multiple people competing for the right of way, crowding, and following in and out.

[0040] The connecting rod transmission assembly arranged between adjacent bottom plates 5 has the function of driving the multi-channel gate mechanism to switch the form, and cooperates with the telescopic electric door structure 2 to achieve different needs of entering and exiting the venue. As a preferred embodiment, it is aimed at the situation of primary school students entering and exiting the school gate;

[0041] like Figures 1 to 7 As shown, the multi-channel gate mechanism is expanded into a linear distribution state. Under the action of the connecting member 3, a channel gate device is formed with the telescopic electric door structure 2. It is a face recognition entry and exit state under large flow, such as during school hours: when the multi-channel gate mechanism is expanded into a linear distribution and acts on the telescopic electric door structure 2, as shown Figure 6 As shown, this state can be used during the student arrival and departure periods to allow multiple groups of students to enter and leave the school at the same time. Figure 7 As shown, the black arrows point to the direction of inflow and outflow of human traffic;

[0042] like Figure 8 and 9 As shown: the multi-channel gate mechanism is shrunk into a polygonal shape, and the bottom plates 5 are preferably eight, that is, when the multi-channel gate mechanism is shrunk into a regular octagonal structure, the four entrance and exit facial recognition gate seats are staggered, as shown in FIG. Figure 9 As shown by the arrows, under the action of the telescopic electric door structure 2, there are different implementation methods. The telescopic electric door structure 2 is an existing mature technology, which can be horizontally limited and telescopically moved:

[0043] Under the condition that the multi-channel gate mechanism is contracted into an octagonal shape, when the telescopic electric door structure 2 is extended, as shown in FIG. Figure 9 In the state shown, the left vertical side of the octagonal multi-channel gate mechanism abuts the wall. The channel gate structure formed at this time can be used during school hours, that is, when there is no traffic going to and from school. In this mode, students are required to undergo facial recognition twice whether entering or leaving the school. By analyzing the number of facial recognitions and the direction of entry and exit of each student, it can be determined whether students and faculty members are leaving early or arriving late in an unsupervised environment.

[0044] Under the condition that the multi-channel gate mechanism is contracted into an octagonal shape, when the telescopic electric door structure 2 is shortened: for vehicles entering and exiting, but this process requires the supervision of security personnel, during this period, the multi-channel gate mechanism is contracted into a polygonal shape, and in conjunction with the shortening of the telescopic electric door structure 2, the switching state is as follows Figures 6 to 8 As shown, it can be applied to vehicles passing through and controlling the multi-channel gate mechanism. Figures 9 to 8 State to enable the passage of vehicles and large cargo;

[0045] In case of school emergencies and the need to quickly evacuate students, there is no need to scan students' faces. Figure 8 Status is enough.

[0046] This design can switch the state of the multi-channel gate mechanism and the extension and retraction of the retractable electric door structure 2 according to the needs of entering and exiting the venue.

[0047] Example 2

[0048] As another embodiment of the present invention, each group of facial recognition gate seats includes a gate seat 8 fixed on both sides of the bottom plate 5, and a limit gate assembly arranged on the opposite sides of the two gate seats 8, which is used to limit the passage of a single person; there are two groups of limit gate assemblies, which are respectively arranged on the opposite sides of the gate seat 8, and each group of limit gate assemblies includes a mounting groove opened on the inner wall of the gate seat 8, a mounting rod 12 is fixed inside the mounting groove, and a fixing sleeve 20 is respectively fixed to the two ends of the mounting rod 12, and also includes a movable sleeve 19 slidably installed in the middle of the mounting rod 12, and a second sleeve 19 is respectively provided between the movable sleeve 19 and the two fixed sleeves 20. A transmission frame assembly and a second transmission frame assembly, and the first transmission frame assembly and the second transmission frame assembly are distributed front and back along the direction of travel; the first transmission frame assembly and the second transmission frame assembly are also respectively provided with a first barrier structure and a second barrier structure, the first barrier structure serves as the main gate of the gate base 8, used to control the entry and exit of personnel, and the second barrier structure is used to prevent outsiders from following and entering the gate base 8; it also includes a facial recognition module set on the gate base 8 for identifying personnel; and an electric telescopic rod 27 set between the movable sleeve 19 and one of the fixed sleeves 20, used to drive the operation of the movable sleeve 19.

[0049] This embodiment, such as Figure 12 As shown, by setting the first transmission frame assembly and the second transmission frame assembly, when the movable sleeve 19 operates, the first transmission frame assembly expands and the second transmission frame assembly must contract. If the first transmission frame assembly contracts, the second transmission frame assembly must expand, as shown in FIG. Figure 10-13 As shown, in conjunction with the first barrier structure and the second barrier structure respectively provided on the first transmission frame assembly and the second transmission frame assembly, it is possible to achieve the effect of single-person passage while simultaneously preventing outsiders from entering the device while realizing the identification of passing personnel;

[0050] Specific examples Figure 13 shown, and Figure 13 The state is the initial state of the facial recognition gate seat, that is, the first barrier structure is closed and the second barrier structure is open. When a person passes through the facial recognition gate seat and completes the recognition through the facial recognition module, the electric telescopic rod 27 retracts to open the first barrier structure and close the second barrier structure. When the person passes through, the outsiders are blocked, thereby avoiding the situation where the outsiders are trapped due to following, and the safety performance is improved.

[0051] Furthermore, the first transmission frame assembly includes two connecting blocks 17, and the two connecting blocks 17 are respectively arranged on the movable sleeve 19 and the fixed sleeve 20, and also includes a transmission rod 15 rotatably connected to each connecting block 17 through a first pin shaft, and the opposite ends of the two transmission rods 15 are respectively rotatably connected to the first mounting member 21 through a second pin shaft, and the first partition structure is arranged on the first mounting member 21; the first transmission frame assembly and the second transmission frame assembly have the same structure, and the second partition structure is arranged on the first mounting member 21 where the second transmission frame assembly is located.

[0052] like Figure 11 、 13 As shown, the movable sleeve 19 and the fixed sleeve 20 are respectively rotatably connected to the transmission rod 15 through the connecting block 17 thereon, and the opposite ends of the two transmission rods 15 are respectively rotatably connected to the first mounting member 21 through the second pin shaft. The first barrier structure and the second barrier structure are respectively arranged on the first mounting member 21 where the first transmission frame assembly and the second transmission frame assembly are located. Figure 13 As shown, when the power provided by the electric telescopic rod 27 moves the movable sleeve 19, the first transmission frame assembly where the two limit gate assemblies are located is brought closer, while the second transmission frame assembly is moved away, thereby closing the first barrier structure and opening the second barrier structure. This state is the initial state. Similarly, after face recognition, the facial recognition module sends information to the control system inside the device, and the control system controls the operation of the electric telescopic rod 27, thereby switching the states of the first transmission frame assembly and the second transmission frame assembly, that is, opening the first barrier structure and closing the second barrier structure to block outsiders.

[0053] Furthermore, each set of first barrier structures includes a stopper 13 fixed on the first mounting member 21 , and the arc portions of the stoppers 13 of the two first barrier structures can abut against each other.

[0054] Since the stopper 13 is fixed on the first mounting member 21 where the first transmission frame assembly is located, the electric telescopic rod 27 is extended and retracted to make the movable sleeve 19 movable. Through the transmission action of the transmission rod 15, the two stoppers 13 can be moved relative to or away from each other. When the two stoppers 13 collide, Figure 13 As shown, the entry of passing personnel can be blocked, and when the two stoppers 13 are opened, they are used to allow the entry of passing personnel.

[0055] Furthermore, each set of second baffle structures includes a connecting bar 18 fixed on the first mounting member 21 where the second transmission frame assembly is located, and a baffle 11 fixed to the rear end of the connecting bar 18, and the arc portions of the baffle 11 where the two second baffle structures are located run relative to each other.

[0056] like Figure 13As shown, since the connecting bar 18 is fixed on the first mounting member 21 where the second transmission frame assembly is located, the baffle 11 provided at the rear end of the connecting bar 18 can block outsiders when the two second transmission assemblies are close to each other.

[0057] Furthermore, the facial recognition module includes an identification panel 10 arranged on the upper part of the side wall of one of the gate bases 8, and several hydraulic telescopic cylinders 23 arranged in the middle of the base plate 5, and also includes a support plate 16 fixed to the telescopic ends of the hydraulic telescopic cylinders 23, and the support plate 16 is used to lift and support the passing personnel so that the passing personnel can be recognized for their faces.

[0058] Facial recognition turnstiles are a mature technology. Their working principle is mainly to collect facial image information of the person to be inspected, and determine the identity of the person to be inspected based on the facial image information, so as to release or prohibit the person from passing. For the facial recognition system for schools in this application, the following are specifically implemented: S1: Establishing a school personnel identity database, and establishing a local access policy database based on the access policy issued by the cloud backend; S2: Image verification module, comparing the facial image of the person passing through collected by the recognition panel 10 with the student identity database, verifying the identity of the person passing through based on the comparison result, querying the corresponding access policy in the access policy database based on the identity of the person passing through, and generating corresponding control instructions based on the access policy;

[0059] Since the support plate 16 is provided at the telescopic end of the hydraulic telescopic cylinder 23, the height of the support plate 16 can be set to meet the needs of students of different heights, as the heights of students in grades 1-6 of the primary school vary.

[0060] The upper surface of the gate seat 8 is also provided with a control panel 9, such as Figure 11 、 12 As shown, through the control panel 9, when the recognition panel 10 fails, swiping the student ID, work ID and entering the student ID and work ID can pass the facial recognition gate.

[0061] Example 3

[0062] As other embodiments of the present invention, each group of connecting rod transmission assemblies includes a mounting plate 6, and the corners at which the rear ends of adjacent base plates 5 are located are rotatably connected to the mounting plate 6 through first rotating shafts 26; and a hydraulic rod 24 fixed to the bottom of the mounting plate 6, and the two ends of the second mounting member 25 fixed at the telescopic end of the hydraulic rod 24 are rotatably connected to the connecting rod 14 through the second rotating shaft, and the opposite ends of the two connecting rods 14 are rotatably connected to the front corners of the adjacent base plates 5 through third rotating shafts. When the hydraulic rod 24 telescopically moves, the adjacent base plates 5 are moved closer to and away from each other.

[0063] Since the rear sides of the adjacent gate seats 8 are rotatably connected to the mounting plate 6 via the first rotating shaft 26, as shown in FIG. Figure 14As shown, the support column 7 fixed at the bottom of the mounting plate 6 and the hydraulic rod 24 fixed on the support column 7, and the hydraulic rod 24 is rotatably connected to the two connecting rods 14 through the second mounting piece 25 at its telescopic end, and the two connecting rods 14 are rotatably connected to the front side of the adjacent gate seat 8. Therefore, when the hydraulic rod 24 is telescopically moved, the adjacent gate seat 8 can be deflected about the axis of the first rotating shaft 26 where the mounting plate 6 is located. When several hydraulic rods 24 are driven to extend synchronously, the left end facial recognition gate seat is approached to the rightmost facial recognition gate seat and an octagonal structure is formed. This state is shown in FIG. Figure 8 As shown, the morphological switching process of the multi-channel gate mechanism is completed.

[0064] Furthermore, a universal wheel 22 is provided at the bottom of each base plate 5. By providing the universal wheel 22, as shown in FIG. Figure 6 As shown, it is convenient for the connecting rod transmission component to drive the multi-channel gate mechanism to switch the form.

[0065] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make various modifications, substitutions, and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention should be determined by the claims.
