Description

Technical Field

[0001] The utility model relates to the technical field of campus access control, and in particular to a smart campus access identification device. Background Art

[0002] A smart campus refers to an integrated intelligent campus work, study and life environment based on the Internet of Things. This integrated environment uses various application service systems as carriers to fully integrate teaching, scientific research, management and campus life.

[0003] Pass identification equipment is also an important part of the smart campus. However, the current pass identification equipment has the following shortcomings:

[0004] In order to match the smart campus card, the existing access identification equipment will set up a card swiping area. In actual use, the RFID read-write magnetic plate is generally in a state of permanent power supply. When the card swiping identification work is carried out, it is easy to repeatedly identify the campus card, resulting in data conflicts or communication delays. At the same time, the permanent power supply will also cause a waste of electricity resources;

[0005] The gate plates of existing passage identification equipment are often directly driven to open by motors or electric push rods. The side of the gate plate away from its rotation axis opens faster and has greater inertia. In actual use, the entire gate plate will bend due to inertia, which will affect the service life of the gate plate in the long run. Utility Model Content

[0006] The purpose of the utility model is to provide a smart campus access identification device to solve the technical problems existing in the above-mentioned background technology.

[0007] To achieve the above purpose, the technical solution of the utility model is as follows:

[0008] A smart campus access identification device includes a gate machine, two of which are symmetrically arranged on the left and right. The gate machine includes: a device body, a gate shaft and a gate plate. Two push-to-power one-card identification components are symmetrically arranged on the front and rear sides of the upper part of the device body. A storage groove is opened on the front inner side of the device body. The gate plate is rotatably connected in the storage groove through the gate shaft. The bottom end of the gate shaft is connected to a driving component for driving its axial rotation, and the speed of the output end of the driving component linearly changes from fast to slow.

[0009] Furthermore, two slopes are symmetrically arranged on the front and rear sides of the upper part of the device body, and a push-to-power-on card identification component is arranged on the slopes.

[0010] Furthermore, the slope has an inclination angle of 15° to 45°.

[0011] Furthermore, the push-to-power-on card identification component includes: an RFID read-write magnetic plate, a contact, a pressure switch, a guide sleeve, a guide column and a spring. The device body is provided with an embedded groove in the middle of the slope, and four sunken grooves are symmetrically provided at the four corners of the bottom end of the embedded groove. A pressure switch is fixedly installed in the middle of the bottom end of the embedded groove, and a contact is fixedly installed in the middle of the bottom end of the RFID read-write magnetic plate. The contact is located directly above the pressure switch, and a guide column is fixedly connected to the bottom end of the sunken groove. Four guide sleeves are symmetrically arranged at the four corners of the bottom end of the RFID read-write magnetic plate, and the four guide sleeves are respectively slidably sleeved on the four guide columns. The lower part of the guide column is sleeved with a spring whose two ends respectively press the bottom end of the guide sleeve and the bottom end of the sunken groove. When the contact contacts the pressure switch, the RFID read-write magnetic plate is powered on to identify the smart campus card. When the contact does not contact the pressure switch, the RFID read-write magnetic plate does not work.

[0012] Furthermore, the device body is also provided with an installation groove below the storage groove, and the gate shaft penetrates from top to bottom and rotates to connect the partition between the storage groove and the installation groove, and the bottom end of the gate shaft is fixedly connected to a driven gear, and the output end of the drive assembly engages with the driven gear.

[0013] Furthermore, the driving assembly includes: an L-shaped driving block, a fixed sleeve, a ball, a driving rod and a servo motor, a bar-shaped tooth portion is arranged on the inner side of the long part of the L-shaped driving block, the bar-shaped tooth portion meshes with the driven gear, a fixed sleeve is penetrated and fixedly connected at the middle position of the short part of the L-shaped driving block, a ball groove is opened on the inner wall of the fixed sleeve, the ball is limited and rollingly connected in the ball groove, the driving rod slides through the fixed sleeve, a thread groove with a pitch gradually decreasing from front to rear is opened on the outer wall of the driving rod, the ball is rollingly connected in the thread groove, the front end of the driving rod is fixedly connected to the output end of the servo motor, and the servo motor is fixedly installed in the mounting groove.

[0014] Furthermore, a cover plate is detachably fixedly mounted on the outer end of the mounting groove.

[0015] Furthermore, a control host is fixedly installed inside the main body of the device, and the control host is electrically connected to the push-to-power-on card identification component and the servo motor respectively.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] By setting up a push-to-power card identification component, when the card is placed on the RFID read-write magnetic plate and pressed down, when the contact contacts the pressure switch, the RFID read-write magnetic plate is powered on to identify the smart campus card; when the contact does not contact the pressure switch, the RFID read-write magnetic plate does not work; the RFID read-write magnetic plate is prevented from being in a state of long-term power supply, thereby avoiding repeated identification of the campus card, and then avoiding data conflicts or communication delays, and at the same time, avoiding waste of electricity resources.

[0018] The driving rod is driven to rotate by a servo motor. At the same time, a thread groove with a pitch gradually decreasing from front to back is opened on the outer wall of the driving rod, and the ball is rollingly connected in the thread groove. A ball groove is opened on the inner wall of the fixed sleeve, and the ball limiter is rollingly connected in the ball groove. The driving rod slides through the fixed sleeve, and the middle position of the short part of the L-shaped driving block is penetrated and fixedly connected with the fixed sleeve, thereby driving the movement speed of the L-shaped driving block to change linearly from fast to slow, ensuring that the movement speed of the gate shaft and gate plate driven by it also changes linearly from fast to slow (that is, the speed is faster at the moment of opening, and the speed slows down when moving to the end point), avoiding large bending of the gate plate due to inertia, thereby ensuring the service life of the gate.

DETAILED DESCRIPTION

[0026] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] See also Figures 1 to 6 As shown, a smart campus access identification device includes a gate machine, two of which are symmetrically arranged on the left and right. The gate machine includes: a device body 1, a gate shaft 8 and a gate plate 9. Two push-on type one-card identification components are symmetrically arranged on the front and back sides of the upper part of the device body 1. A storage groove 103 is opened on the front inner side of the device body 1. The gate plate 9 is rotatably connected in the storage groove 103 through the gate shaft 8. The bottom end of the gate shaft 8 is connected to a driving component for driving its axial rotation, and the speed of the output end of the driving component linearly changes from fast to slow.

[0028] In this embodiment, two slopes are symmetrically arranged on the front and rear sides of the upper part of the device body 1, and the slope inclination angle is 15°~45°. A push-to-power card identification component is arranged on the slope. The setting of the slope facilitates the user to perform card swiping operations.

[0029] In this embodiment, the push-to-power card identification component includes: an RFID read-write magnetic plate 2, a contact 3, a pressure switch 4, a guide sleeve 5, a guide column 6 and a spring 7. The device body 1 is provided with an embedded groove 101 in the middle of the slope, and four sinking grooves 102 are symmetrically provided at the four corners of the bottom of the embedded groove 101. The pressure switch 4 is fixedly installed in the middle of the bottom of the embedded groove 101, and the contact 3 is fixedly installed in the middle of the bottom of the RFID read-write magnetic plate 2. The contact 3 is located directly above the pressure switch 4 and sinks. A guide column 6 is fixedly connected to the bottom end of the groove 102, and four guide sleeves 5 are symmetrically arranged at the four corners of the bottom end of the radio frequency identification read-write magnetic plate 2. The four guide sleeves 5 are respectively slidably sleeved on the four guide columns 6, and the lower part of the guide column 6 is sleeved with a spring 7 at both ends of which respectively press the bottom end of the guide sleeve 5 and the bottom end of the sinking groove 102. When the contact 3 is in contact with the pressure switch 4, the radio frequency identification read-write magnetic plate 2 is powered on to identify the smart campus card. When the contact 3 is not in contact with the pressure switch 4, the radio frequency identification read-write magnetic plate 2 does not work.

[0030] In this embodiment, the device body 1 is further provided with a mounting groove 104 below the storage groove 103. The gate shaft 8 penetrates from top to bottom and rotates to connect the interlayer between the storage groove 103 and the mounting groove 104. The bottom end of the gate shaft 8 is fixedly connected with a driven gear 10, and the output end of the driving component engages with the driven gear 10; the driving component comprises: an L-shaped driving block 11, a fixing sleeve 12, a ball 13, a driving rod 14 and a servo motor 15. A bar-shaped tooth portion is provided on the inner side of the long part of the L-shaped driving block 11, and the bar-shaped tooth portion engages with the driven gear 10. The fixing sleeve 12 is penetrated and fixedly connected at the middle position of the short part of the L-shaped driving block 11. A ball groove is opened on the inner wall of the fixing sleeve 12, and the ball 13 is limitedly and rollingly connected in the ball groove. The driving rod 14 slides through the fixing sleeve 12, and a thread groove with a pitch gradually decreasing from front to back is opened on the outer wall of the driving rod 14. The ball 13 is rollingly connected in the thread groove. The front end of the moving rod 14 is fixedly connected to the output end of the servo motor 15, and the servo motor 15 is fixedly installed in the installation groove 104. The driving rod 14 is driven to rotate by the servo motor 15. At the same time, since a thread groove with a pitch gradually decreasing from front to back is opened on the outer wall of the driving rod 14, the ball 13 is rollingly connected in the thread groove, and a ball groove is opened on the inner wall of the fixed sleeve 12. The ball 13 is limitedly rollingly connected in the ball groove, and the driving rod 14 slides through the fixed sleeve 12. The middle position of the short part of the L-shaped driving block 11 penetrates and is fixedly connected with the fixed sleeve 12, thereby driving the movement speed of the L-shaped driving block 11 to change linearly from fast to slow, ensuring that the movement speed of the gate shaft 8 and the gate plate 9 driven by it also changes linearly from fast to slow (that is, the speed is faster at the moment of opening, and the speed slows down when moving to the end point), avoiding large bending of the gate plate 9 due to inertia, thereby ensuring the service life of the gate plate 9.

[0031] In this embodiment, a cover plate 16 is detachably fixedly mounted on the outer end of the mounting groove 104 .

[0032] In this embodiment, a control host is fixedly installed inside the device body 1, and the control host is electrically connected to the push-to-power card identification component and the servo motor 15 respectively. The operation of the entire device can be well controlled by the set control host.

[0033] When the device is in use, the student or teacher places the smart campus card on the RFID read-write magnetic plate 2, and presses the RFID read-write magnetic plate 2 downward. When the contact 3 contacts the pressure switch 4, the RFID read-write magnetic plate 2 is powered on to identify the smart campus card, and the control host identifies and authenticates the information of the smart campus card. If the identification and authentication are successful, the servo motor 15 drives the gate plate 9 to open; when no students or teachers pass, the contact 3 is separated from the pressure switch 4 under the action of the spring 7, and the RFID read-write magnetic plate 2 does not work; the RFID read-write magnetic plate is prevented from being in a state of long-term power supply, thereby avoiding repeated identification of the campus card, and then avoiding data conflicts or communication delays, and at the same time, avoiding waste of power resources; on the gate plate During the opening process of 9, the servo motor 15 drives the driving rod 14 to rotate. At the same time, since a thread groove with a pitch gradually decreasing from front to back is opened on the outer wall of the driving rod 14, the ball 13 is rollingly connected in the thread groove, and a ball groove is opened on the inner wall of the fixed sleeve 12. The ball 13 is limitedly rollingly connected in the ball groove, and the driving rod 14 slides through the fixed sleeve 12. The fixed sleeve 12 is penetrated and fixedly connected at the middle position of the short part of the L-shaped driving block 11, thereby driving the movement speed of the L-shaped driving block 11 to change linearly from fast to slow, ensuring that the movement speed of the gate shaft 8 and the gate plate 9 driven by it also changes linearly from fast to slow (that is, the speed is faster at the moment of opening, and the speed slows down when moving to the end point), avoiding large bending of the gate plate 9 due to inertia, thereby ensuring the service life of the gate plate 9.
