[0002] Usually, a dedicated campus access control device is installed at the entrance of the campus. The access control system can identify registered persons and allow them to enter, but refuse entry to unregistered persons. The existing technology has the following disadvantages: the gate of the existing access control system is open for only a few seconds and will close immediately after the time is up, which may cause some students to be caught by the gate before they pass through, thus causing harm to the students and leading to unsafe situations. Utility Model Content

[0003] The utility model aims to provide a door access control device for managing the entry and exit of students on campus, which is safer to use, saves parts and saves costs.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A door access control device for managing the entry and exit of students on campus comprises a plurality of shells arranged side by side, each of the shells having a rectangular hollow groove in the middle, a first gate plate and a second gate plate being movably arranged in the rectangular hollow groove in the middle of the shells, the first gate plate and the second gate plate being opened to two sides respectively, the bottom of the shells being hollow, a driving assembly being arranged at the bottom of the shells, and the driving assembly being connected to the first gate plate and the second gate plate.

[0006] Preferably, each shell upper surface is provided with a mounting rod, an intelligent access control identification device is installed on the upper part of the mounting rod, and the intelligent access control identification device is provided with a collection camera, a prompt speaker and a liquid crystal screen; the shell is provided with an IC card identification device.

[0009] Preferably, a normally open switch, a normally closed switch and an emergency switch are provided on the side walls of the rectangular hollow groove in the middle of the shell, and the normally open switch, the normally closed switch and the emergency switch are all electrically connected to the controller.

[0010] Preferably, the driving assembly includes a first column and a second column symmetrically arranged on the upper surface of the hollow part of the bottom of the shell, the first column is connected to a first rotating block through a bearing, the second column is connected to a second rotating block through a bearing, the first rotating block is provided with a first electric telescopic rod, the second rotating block is provided with a second electric telescopic rod, the output end of the first electric telescopic rod is connected to a third rotating block, the output end of the second electric telescopic rod is provided with a fourth rotating block, the third rotating block is connected to a first connecting rod through a bearing, the fourth rotating block is connected to a second connecting rod through a bearing, the first connecting rod is connected to the root of the first gate plate, and the second connecting rod is connected to the root of the second gate plate.

[0011] Preferably, a first right-angle limit block and a second right-angle limit block are symmetrically provided on the upper surface of the hollow part of the bottom of the shell, the first right-angle limit block is adapted to the side wall of the first connecting rod, the second right-angle limit block is adapted to the side wall of the second connecting rod, and the controller is electrically connected to the first electric telescopic rod and the second electric telescopic rod.

[0012] The technical effects achieved by the utility model are:

[0013] In actual use, according to needs, two shells 1 are selected for symmetrical installation, and the spacing between the two shells is 1m, and the two shells form a gate channel, or three shells are sequentially spaced 1m apart and arranged in parallel to form two gate channels. In summary, 2n-1 shells 1 are selected sequentially spaced 1m apart and arranged in parallel to form n gate channels. Compared with the prior art, two shells form one gate channel and four shells form two gate channels, thereby saving resources and saving floor space.

[0014] In the utility model, the administrator presses the normally open switch, and then uses the administrator's IC card to be identified by the IC card identification device. At this time, the controller controls the driving component to make the first gate and the second gate all in the open state.

In actual use, for example, in an emergency situation where the first gate and the second gate clamp students or other objects, the emergency switch is pressed for a long time. At this time, no identity identification is required. The controller opens the first gate and the second gate by controlling the driving component. At the same time, the controller controls the prompt speaker to issue an early warning prompt to prompt the administrator to deal with it in time. When the clamped students or other objects are out of trouble, the emergency switch is pressed for a long time again.

At this time, the controller controls the driving component to make the first gate and the second gate resume normal working procedures. At the same time, the prompt speaker no longer issues an early warning prompt, making the equipment safer to use.

[0015] In the utility model, when the infrared ray emitted by the infrared transmitter near one end is not received by the corresponding infrared receiver, it means that a person has walked into the gate passage; when the infrared ray emitted by the infrared transmitter at the other end is not received by the corresponding infrared receiver, it means that the person has entered the other end of the gate passage; then the infrared ray emitted by the infrared transmitter at the other end is received by the corresponding infrared receiver again, indicating that the person has made the gate passage. At this time, the controller controls the driving component to close the first gate plate and the second gate plate, thereby closing the gate passage, making it safer to use.

[0024] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0025] like Figure 1 As shown, a door access control device for managing the entry and exit of students on campus includes a plurality of shells 1 arranged side by side, each shell 1 has a rectangular hollow groove in the middle, a first gate plate 2 and a second gate plate 3 are movably provided in the rectangular hollow groove in the middle of the shell 1, the first gate plate 2 and the second gate plate 3 are opened to two sides respectively, the bottom of the shell 1 is hollow, a driving assembly 4 is provided at the bottom of the shell 1, and the driving assembly 4 is connected to the first gate plate 2 and the second gate plate 3.

[0026] In actual use, according to needs, two shells 1 are selected for symmetrical installation, and the interval between the two shells 1 is 1m, and the two shells 1 form a gate channel, or three shells 1 are sequentially spaced 1m apart and arranged in parallel to form two gate channels. In summary, 2n-1 shells 1 are selected sequentially spaced 1m apart and arranged in parallel to form n gate channels.

[0027] Compared with the prior art, two shells 1 form one gate passage, and four shells 1 form two gate passages, thereby saving resources and floor space.

[0028] A mounting rod 5 is provided on the upper surface of each housing 1, and an intelligent access control identification device 6 is installed on the upper part of the mounting rod 5. The intelligent access control identification device 6 is provided with a collection camera 601, a prompt speaker 602 and a liquid crystal screen 603; an IC card identification device 10 is provided on the housing 1.

[0029] like Figure 2 As shown, in the present invention, the IC card recognition device 10 is used to recognize the student's campus card to complete identity authentication. Identity authentication can also be performed through face recognition through the acquisition camera 601. Here, the IC card recognition device 10 and the acquisition camera 601 are obtained through procurement and will not be described in detail here.

[0030] A controller 7 is disposed inside each housing 1 , and the controller 7 is electrically connected to the intelligent access control recognition device 6 and the IC card recognition device 10 .

[0031] It should be added that the controller 7 is obtained through purchase, and it is common knowledge for people in the art that the controller 7 controls the intelligent access control identification device 6 and the IC card identification device 10, which will not be elaborated here.

[0032] Two infrared sensors 8 are disposed on each housing 1 . One end of the infrared sensor 8 is an infrared transmitter 801 , and the other end of the infrared sensor 8 is an infrared receiver 802 . The controller 7 is electrically connected to the infrared sensor 8 .

[0033] like Figure 1 , Figure 2 as well as Figure 3 As shown, the infrared transmitter 801 on one shell 1 corresponds to the infrared receiver 802 on the adjacent shell 1. When the infrared ray emitted by the infrared transmitter 801 near one end is not received by the corresponding infrared receiver 802, it means that a person has walked into the gate passage. When the infrared ray emitted by the infrared transmitter 801 at the other end is not received by the corresponding infrared receiver 802, it means that the person has entered the other end of the gate passage. Then, the infrared ray emitted by the infrared transmitter 801 at the other end is received by the corresponding infrared receiver 802 again, indicating that the person has made a gate passage. At this time, the controller 7 controls the driving component 4 to close the first gate plate 2 and the second gate plate 3, thereby closing the gate passage.

[0034] A normally open switch 11 , a normally closed switch 12 and an emergency switch 13 are provided on the side wall of the rectangular hollow groove in the middle of the housing 1 . The normally open switch 11 , the normally closed switch 12 and the emergency switch 13 are all electrically connected to the controller 7 .

[0035] like Figure 3 As shown, in actual use, the administrator presses the normally open switch 11, and then uses the administrator's IC card to be identified by the IC card identification device 10. At this time, the controller 7 controls the drive component 4 to make the first gate 2 and the second gate 3 all in the open state. Similarly, the administrator presses the normally closed switch 12, and then uses the administrator's IC card to be identified by the IC card identification device 10. At this time, the controller 7 controls the drive component 4 to make the first gate 2 and the second gate 3 all in the normally closed state. In actual use, for example, in an emergency situation where the first gate 2 and the second gate 3 clamp students or other items, the emergency switch 13 is pressed for a long time. At this time, no identity identification is required. The controller 7 opens the first gate 2 and the second gate 3 by controlling the drive component 4. At the same time, the controller 7 controls the prompt speaker 602 to issue an early warning prompt to prompt the administrator to deal with it in time. When the clamped students or other items are out of trouble, the emergency switch 13 is pressed for a long time again. Then, the administrator's IC card is used to be identified by the IC card identification device 10. At this time, the controller 7 controls the drive component 4 to make the first gate 2 and the second gate 3 resume the normal working process, and the prompt speaker 602 no longer issues an early warning prompt.

[0036] It must be said that the control system between the controller 7 and the normally open switch 11, the normally closed switch 12, the emergency switch 13, the drive component 4, the IC card recognition device 10 and the prompt speaker 602 is common knowledge to those skilled in the art and will not be elaborated here. Similarly, in the present utility model, when an outsider presses and holds the emergency switch 13, although the first gate plate 2 and the second gate plate 3 can be opened, the prompt speaker 602 can issue an early warning prompt to promptly prompt the management personnel to handle the situation, thereby greatly ensuring the safety of the gate machine.

[0037] like Figure 6 As shown, the driving assembly 4 includes a first column 401 and a second column 402 symmetrically arranged on the upper surface of the hollow part of the bottom of the shell 1, the first column 401 is connected to a first rotating block 403 through a bearing, the second column 402 is connected to a second rotating block 404 through a bearing, the first rotating block 403 is provided with a first electric telescopic rod 405, the second rotating block 404 is provided with a second electric telescopic rod 406, the output end of the first electric telescopic rod 405 is connected to a third rotating block 407, the output end of the second electric telescopic rod 406 is provided with a fourth rotating block 408, the third rotating block 407 is connected to a first connecting rod 409 through a bearing, the fourth rotating block 408 is connected to a second connecting rod 410 through a bearing, the first connecting rod 409 is connected to the root of the first gate plate 2, and the second connecting rod 410 is connected to the root of the second gate plate 3.

[0038] like Figure 6 As shown, in actual use, under the control of the controller 7, when the output end of the first electric telescopic rod 405 extends outward, the root of the first electric telescopic rod 405 rotates around the first column 401 through the first rotating block 403, and similarly, the output end of the first electric telescopic rod 405 rotates around the first connecting rod 409 through the third rotating block 407, so that the first connecting rod 409 drives the first gate plate 2 to rotate 90°, thereby completing the opening of the first gate plate 2. Similarly, when the output end of the first electric telescopic rod 405 contracts inward, the first gate plate 2 is closed.

[0039] like Figure 6 As shown, in actual use, under the control of the controller 7, when the output end of the second electric telescopic rod 406 extends outward, the root of the second electric telescopic rod 406 rotates around the second column 402 through the second rotating block 404, and similarly, the output end of the second electric telescopic rod 406 rotates around the second connecting rod 410 through the fourth rotating block 408, so that the second connecting rod 410 drives the second gate plate 3 to rotate 90°, thereby completing the opening of the second gate plate 3. Similarly, when the output end of the second electric telescopic rod 406 contracts inward, the second gate plate 3 is closed.

[0040] like Figure 1As shown, it should be supplemented that when two or more gate channels are arranged side by side, the first gate plate 2 and the first electric telescopic rod 405 on the shell 1 at the initial end are not installed, and similarly, the second gate plate 3, the second electric telescopic rod 406, the intelligent access control identification device 6 and the IC card identification device 10 on the shell 1 at the farthest end are not installed, so as to save equipment and reduce costs.

[0041] A first right-angle limit block 411 and a second right-angle limit block 412 are symmetrically provided on the upper surface of the hollow bottom of the shell 1. The first right-angle limit block 411 is adapted to the side wall of the first connecting rod 409, and the second right-angle limit block 412 is adapted to the side wall of the second connecting rod 410. The controller 7 is electrically connected to the first electric telescopic rod 405 and the second electric telescopic rod 406.

[0042] By setting the first right-angle limit block 411 and the second right-angle limit block 412, the first connecting rod 409 and the second connecting rod 410 can only move within a range of 90 degrees, thereby adapting to the opening or closing of the first gate plate 2 and the second gate plate 3, making the movement position of the first gate plate 2 and the second gate plate 3 more precise.

[0043] like Figure 1-6As shown, the working principle of the utility model is: first install the equipment, and according to the needs, select two shells 1 to be installed symmetrically, and the spacing between the two shells 1 is 1m, and the two shells 1 form a gate channel, or three shells 1 are spaced 1m apart in sequence and arranged in parallel to form two gate channels. In summary, 2n-1 shells 1 are selected to be spaced 1m apart in sequence and arranged in parallel to form n gate channels; when two or more gate channels are arranged side by side, the first gate plate 2 and the first electric telescopic rod 405 on the shell 1 at the initial end are not installed, and similarly the second gate plate 3, the second electric telescopic rod 406, and the intelligent access control recognition device 6 on the shell 1 at the farthest end are not installed. And IC card recognition device 10 are not installed, so as to save equipment and reduce costs; then the electrical system is debugged, for example, the first electric telescopic rod 405 on the second housing 1 is connected to the controller 7 on the first housing 1, and the first electric telescopic rod 405 on the third housing 1 is connected to the controller 7 on the second housing 1, and so on; the controller 7 in the first housing 1 is used to control the second gate plate 3 of the first housing 1 and the first gate plate 2 of the second housing 1 in the first gate channel to open or close. The correct access control system here is common knowledge known to those skilled in the art and will not be described in detail; when a student uses a campus card in the IC card recognition device 10 After the above recognition is completed, or after the recognition is completed by the acquisition camera 601, under the control of the controller 7, the second gate 3 and the first gate 2 in the current gate channel are opened, and the student enters the gate channel. When the infrared ray emitted by the infrared transmitter 801 near one end is not received by the corresponding infrared receiver 802, it means that the person has walked into the gate channel. When the infrared ray emitted by the infrared transmitter 801 at the other end is not received by the corresponding infrared receiver 802, it means that the person has entered the other end of the gate channel. Then the infrared ray emitted by the infrared transmitter 801 at the other end is received by the corresponding infrared receiver 802 again. The personnel have made the gate passage, and at this time, the controller 7 controls the driving assembly 4 to close the first gate plate 2 and the second gate plate 3, so as to close the gate passage again; specifically, under the control of the controller 7, when the output end of the first electric telescopic rod 405 extends outward, the root of the first electric telescopic rod 405 rotates around the first column 401 through the first rotating block 403, and similarly, the output end of the first electric telescopic rod 405 rotates around the first connecting rod 409 through the third rotating block 407, so that the first connecting rod 409 drives the first gate plate 2 to rotate 90°, and the first gate plate 2 is opened. Similarly, when the output end of the first electric telescopic rod 405 contracts inward, the first gate plate 2 is closed;Under the control of the controller 7, when the output end of the second electric telescopic rod 406 extends outward, the root of the second electric telescopic rod 406 rotates around the second column 402 through the second rotating block 404, and similarly, the output end of the second electric telescopic rod 406 rotates around the second connecting rod 410 through the fourth rotating block 408, so that the second connecting rod 410 drives the second gate plate 3 to rotate 90°, thereby completing the opening of the second gate plate 3. Similarly, when the output end of the second electric telescopic rod 406 contracts inward, the second gate plate 3 is closed. The administrator presses the normally open switch 11, and then uses the administrator's IC card to be identified by the IC card identification device 10. At this time, the controller 7 controls the drive component 4 to make the first gate plate 2 and the second gate plate 3 all in the open state. Similarly, the administrator presses the normally closed switch 12, and then uses the administrator's IC card to be identified by the IC card identification device 10. After the device 10 recognizes, the controller 7 controls the driving component 4 to make the first gate 2 and the second gate 3 all in the normally closed state. In actual use, for example, in an emergency situation where the first gate 2 and the second gate 3 clamp students or other items, the emergency switch 13 is long pressed. At this time, no identity recognition is required. The controller 7 controls the driving component 4 to open the first gate 2 and the second gate 3. At the same time, the controller 7 controls the prompt speaker 602 to issue an early warning prompt to prompt the management personnel to deal with it in time. When the clamped students or other items are out of trouble, the emergency switch 13 is long pressed again, and then the IC card of the management personnel is used to be recognized by the IC card recognition device 10. At this time, the controller 7 controls the driving component 4 to make the first gate 2 and the second gate 3 resume the normal working process, and the prompt speaker 602 no longer issues an early warning prompt. ;

[0044] It should be added that the model of the chip used inside the controller 7 is: MM32F031C6T6; the controller 7 also includes a data acquisition card and other circuits. The controller 7 is common knowledge to those in the field and will not be described in detail here. The model of the IC card recognition device 10 is: WG1060C; the model of the infrared transmitter 801 is: JBP8020Z-001; the model of the infrared receiver 802 is: conm / 4c300; all circuit systems involved in this device are common knowledge to those in the field and will not be described in detail here.

[0045] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
