Description

Technical Field

[0001] This invention relates to the field of electromechanical technology, specifically to a smart card issuing device for highway toll stations based on biometric recognition. Background Technology

[0002] A smart card issuing machine at a toll station is an automated device used at toll stations on highways, bridges, and tunnels. It is mainly used to issue toll cards or electronic tags to help vehicles pass through toll stations quickly and without obstacles.

[0003] Patent publication number CN219456874U relates to a smart card issuing device for highway toll stations based on biometric recognition. By placing at least two card storage components on a conveyor belt and using the interchangeability of the two card storage components, an uninterrupted card supply can be ensured, allowing vehicles to pass through in a timely manner and avoiding congestion. Through the contraction and extension of the telescopic component, the contraction component can deliver the card to drivers at different parking locations, avoiding situations where drivers park far away and need to get out of their vehicles to retrieve the card, saving vehicle passage time and reducing traffic congestion.

[0004] In the aforementioned patent, the replacement of two card storage components ensures timely vehicle operation and avoids congestion. However, the sizes of small and large vehicles are not uniform when transferring toll cards, which may cause inconvenience for drivers to retrieve cards. Therefore, a smart card issuing device for highway toll stations based on biometric recognition is designed, which has an intelligent card issuing function with intelligent recognition. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a smart card issuing device for highway toll stations based on biometric recognition, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a smart card issuing device for highway toll stations based on biometric recognition, comprising a card issuing machine, a ventilation plate fixedly mounted on the surface of the card issuing machine, a hybrid camera rotatably mounted on the surface of the card issuing machine, an electrically retractable button fixedly mounted on the surface of the card issuing machine, and a card issuing mechanism for handing the card to the driver after recognition provided on the inner wall of the card issuing machine. The card issuing mechanism includes an electrically operated slider slidably mounted on the inner wall of the card issuing machine, an electrically retractable plate rotatably mounted on the surface of the electrically operated slider, an extension plate slidably mounted inside the electrically retractable plate, and an electrically rotating plate rotatably mounted at the end of the extension plate away from the electrically retractable plate. The inner wall of the electrically rotating plate rotates. The toll station is equipped with a rotating arc plate, inside which an electric clamping plate is slidably installed. A protective cover is fixedly installed on the surface of the card issuing machine, and a protective plate is slidably installed on the inner wall of the protective cover. A telescopic spring rod is fixedly installed on the inner wall of the protective cover. A sealing plate is fixedly installed on the circumferential surface of the electric telescopic plate, and a fixing plate is fixedly installed on the circumferential surface of the electric telescopic plate. A fixing rod is fixedly installed on the surface of the protective plate. A rotating plate is rotatably installed at the end of the fixing plate away from the electric telescopic plate. This system improves the efficiency of the toll station. When a vehicle passes through the toll station, the hybrid camera identifies the vehicle and selects an appropriate method to issue a card based on the vehicle size, thereby reducing queuing time for manual card issuance, reducing reliance on manual labor, lowering labor costs, and saving human resources.

[0007] According to the above technical solution, the free end of the telescopic spring rod is fixedly connected to the protective plate, the closed plate is slidably connected to the surface of the protective cover, the hybrid camera consists of an identification module and a transmission module, the hybrid camera is electrically connected to the electric slider, the hybrid camera is electrically connected to the card ejection block, the electric telescopic button is electrically connected to the electric slider, and the hybrid camera is electrically connected to the electric clamping plate. The protective plate moves under the action of the fixed rod until it releases the limit on the electric telescopic plate. The protective plate can prevent the equipment from degrading in performance due to the influence of wind, sand and dust.

[0008] According to the above technical solution, the end of the fixed rod away from the protective plate is rotatably connected to the rotating plate, and the surface of the electric rotating plate away from the card issuer is set as an arc surface to avoid damaging the circuit or causing system crash, thereby improving the stability and reliability of the equipment.

[0009] According to the above technical solution, the surface of the protective cover is provided with a protective device for protecting the electric slider. The protective device includes a rotating block, which is fixedly installed on the surface of the protective cover. A protective plate is rotatably installed on the circumferential surface of the rotating block. A telescopic spring plate is fixedly installed on the inner wall of the card dispenser. A spring connecting rod is fixedly installed on the surface of the protective cover. A second fixing rod is fixedly installed on the surface of the protective plate. A telescopic connecting plate is rotatably installed at the end of the second fixing rod away from the protective plate. An anti-touch plate is slidably installed on the surface of the card dispenser. A third fixing rod is fixedly installed on the surface of the anti-touch plate. A second telescopic spring rod is fixedly installed on the surface of the card dispenser. An extension rod is fixedly installed on the surface of the electric telescopic plate. Under the action of the telescopic connecting plate, the plate moves upward until it releases the limit on the electric telescopic button, avoiding card dispensing errors caused by accidental touch or misoperation, ensuring the accuracy of each card dispensing process, avoiding unnecessary confusion and delays, reducing accidents or card dispensing failures caused by human error, and ensuring stable system operation.

[0010] According to the above technical solution, the spring connecting rod is fixedly connected to the protective plate, and the free end of the telescopic spring rod II is fixedly connected to the anti-touch plate, thereby releasing the limit on the card block and effectively preventing short circuits or corrosion of electronic components caused by excessive humidity. Moisture may also cause the card to get stuck, affecting the card issuing process. The protective plate can effectively isolate external moisture and reduce the chance of moisture entering the equipment, thereby ensuring that the equipment is not affected by humidity changes and further improving the stability and reliability of the equipment.

[0011] According to the above technical solution, the surface of the protective plate is set as an arc surface II. The protective plate contacts the protective plate and moves towards the protective cover until it fits against the protective plate to limit the protective cover. This can reduce the impact of temperature difference caused by changes in ambient temperature on the card issuing device, help improve the durability of the equipment, extend the service life of the equipment, and reduce failures or damage caused by moisture.

[0012] According to the above technical solution, the circumferential surface of the electric telescopic plate is provided with an anti-clogging device for cleaning the surface of the ventilation plate. The anti-clogging device includes a clamping plate, which is fixedly installed on the circumferential surface of the extension rod. A fixing block is fixedly installed on the surface of the clamping plate, and a rotating shaft is rotatably passed through the surface of the fixing block. A turntable is fixedly installed on the circumferential surface of the rotating shaft, and a brush cylinder is fixedly installed on the circumferential surface of the rotating shaft. A sliding block is slidably installed on the inner wall of the card dispenser, and a telescopic spring rod is fixedly installed on the inner wall of the card dispenser. This improves the stability of the clamping plate during subsequent movement, enabling more efficient and stable completion of the cleaning operation, reducing the failure rate, improving cleaning efficiency, and making the cleaning work more efficient and reliable, thereby providing a guarantee for the long-term operation of the equipment.

[0013] According to the above technical solution, a brush plate is provided on the circumferential surface of the brush cylinder, the free end of the telescopic spring rod three is fixedly connected to the sliding block, and a slot is opened on the surface of the card plate. The inner wall of the slot fits against the sliding block to brush off dust or impurities attached to or adhering to the surface of the ventilation plate, thereby preventing the ventilation holes from being blocked and affecting the heat dissipation of the card issuing machine, which would lead to an increase in the temperature of the card issuing machine and affect the normal operation of the equipment. Regularly cleaning the ventilation holes and ensuring unobstructed ventilation helps to prevent the equipment from overheating, thereby improving the operational stability of the equipment and extending its service life.

[0014] This invention provides a smart card issuing device for highway toll stations based on biometric recognition. It has the following advantages:

[0015] (1) The intelligent card issuing device for highway toll stations based on biometric recognition drives the electric rotating plate to rotate through the rotation of the extension plate. When the electric rotating plate rotates to the horizontal, the rotating arc plate flips the clamped billing card. The electric slider moves to a horizontal height closer to the driver and then delivers the billing card to the driver's window. This greatly reduces manual intervention and improves the working efficiency of the toll station. When a vehicle passes through the toll station, the hybrid camera recognizes the vehicle and selects an appropriate method to issue the card according to the size of the vehicle, thereby reducing the queuing time for manual card issuance, reducing reliance on manual labor, thereby reducing labor costs, saving human resources, reducing waiting time, thereby improving the driver's experience of passing through the station, and avoiding the risk of human error, reducing errors and accidents caused by manual operation.

[0016] (2) The intelligent card issuing device for highway toll stations based on biometric recognition drives the fixed plate to rotate through the rotation of the electric telescopic plate, and the rotation of the fixed plate drives the rotating plate to rotate. At the same time, the rotation of the rotating plate drives the fixed rod to move, and the movement of the fixed rod drives the protective plate to move upward. The protective plate moves under the action of the fixed rod until the limit on the electric telescopic plate is released. The protective plate can prevent the equipment from being affected by wind, sand and dust at the toll station, or even cause the system to crash, thereby improving the stability and reliability of the equipment.

[0017] (3) The intelligent card issuing device for highway toll stations based on biometric recognition moves the telescopic connecting plate through the movement of the fixed rod two, which in turn moves the anti-touch plate. The anti-touch plate moves upward under the action of the telescopic connecting plate until it releases the limit on the electric telescopic button, thus avoiding card issuance errors caused by accidental touch or misoperation, ensuring the accuracy of each card issuing process, avoiding unnecessary confusion and delays, reducing accidents or card issuance failures caused by human error, and ensuring the stable operation of the system.

[0018] (4) The intelligent card issuing device for highway toll stations based on biometric recognition rotates under the action of the extension plate by the electric rotating plate. The electric rotating plate rotates and contacts and squeezes the protective plate to rotate, releasing the limit on the card issuing block. This effectively avoids short circuits or corrosion of electronic components caused by excessive humidity. Moisture may also cause the card to get stuck, affecting the card issuing process. The protective plate can effectively isolate external moisture and reduce the chance of moisture entering the equipment, thereby ensuring that the equipment is not affected by humidity changes, further improving the stability and reliability of the equipment. The electric rotating plate returns to its original position and re-contacts and squeezes the free end of the telescopic spring plate to move away from the protective plate. At this time, the protective plate moves towards the protective cover under the action of the spring linkage until it fits with the protective plate and limits the protective cover. This can reduce the impact of temperature difference caused by changes in ambient temperature on the card issuing device, help improve the durability of the equipment, extend the service life of the equipment, and reduce failures or damage caused by moisture.

[0019] (5) The intelligent card issuing device for highway toll stations based on biometric recognition improves the stability of the card plate in subsequent movement by rotating the card plate towards the ventilation plate until the card slot on its surface is in contact with the sliding block. This makes the cleaning operation more efficient and stable, reduces the failure rate, improves the cleaning efficiency, and makes the cleaning work more efficient and reliable, thus providing a guarantee for the long-term operation of the equipment. The rotation of the turntable drives the brush cylinder to rotate, and at the same time, the rotation of the brush cylinder drives the brush plate to rotate, brushing off the dust or impurities attached to or adhering to the surface of the ventilation plate. This avoids the ventilation holes from being blocked, affecting the heat dissipation of the card issuing machine, which in turn causes the temperature of the card issuing machine to rise and affect the normal operation of the equipment. Regularly cleaning the ventilation holes ensures unobstructed ventilation, which helps to prevent the equipment from overheating, thereby improving the operational stability of the equipment and extending its service life.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-9One embodiment of the present invention is: a smart card issuing device for highway toll stations based on biometric recognition, comprising a card issuing machine 1, a ventilation plate 2 fixedly mounted on the surface of the card issuing machine 1, a hybrid camera 3 rotatably mounted on the surface of the card issuing machine 1, an electric telescopic button 41 fixedly mounted on the surface of the card issuing machine 1, and a card issuing device for handing the card to the driver after recognition provided on the inner wall of the card issuing machine 1. The card issuing device includes an electric slider 51, which is slidably mounted on the inner wall of the card issuing machine 1. An electric telescopic plate 52 is rotatably mounted on the surface of the electric slider 51, an extension plate 53 is slidably mounted inside the electric telescopic plate 52, and an electric rotating plate 54 is rotatably mounted at the end of the extension plate 53 away from the electric telescopic plate 52. A rotating arc plate 55 is rotatably installed on the inner wall of the rotating plate 54. An electric clamping plate 56 is slidably installed inside the rotating arc plate 55. A protective cover 57 is fixedly installed on the surface of the card issuing machine 1. A protective plate 58 is slidably installed on the inner wall of the protective cover 57. A telescopic spring rod 59 is fixedly installed on the inner wall of the protective cover 57. A sealing plate 510 is fixedly installed on the circumferential surface of the electric telescopic plate 52. A fixing plate 511 is fixedly installed on the circumferential surface of the electric telescopic plate 52. A fixing rod 512 is fixedly installed on the surface of the protective plate 58. A rotating plate 513 is rotatably installed at the end of the fixing plate 511 away from the electric telescopic plate 52. The rotation of the electric telescopic plate 52 drives the fixing plate 511 to rotate, and the rotation of the fixing plate 511 drives the rotating plate 513 to rotate.

[0032] The free end of the telescopic spring rod 59 is fixedly connected to the protective plate 58, the closed plate 510 is slidably connected to the surface of the protective cover 57, the hybrid camera 3 consists of an identification module and a transmission module, the hybrid camera 3 is electrically connected to the electric slider 51, the hybrid camera 3 is electrically connected to the card dispensing block 42, the electric telescopic button 41 is electrically connected to the electric slider 51, the hybrid camera 3 is electrically connected to the electric clamping plate 56, and the electric clamping plate 56 moves toward the card dispensing block 42 until the billing card is clamped.

[0033] The end of the fixed rod 512 away from the protective plate 58 is rotatably connected to the rotating plate 513. The surface of the electric rotating plate 54 away from the card dispenser 1 is set as an arc surface. The extension plate 53 rotates to drive the electric rotating plate 54 to rotate until it is horizontal.

[0034] In this embodiment, when a vehicle passes through the card dispenser 1, the driver opens the window. The hybrid camera 3 identifies the driver's biometrics and the vehicle's size and model. Simultaneously, the transmission module transmits signals to the card dispensing block 42, the electric slider 51, and the electric clamping plate 56. The card dispensing block 42 ejects the billing card, and the electric clamping plate 56 moves closer to the card dispensing block 42 until it clamps the billing card. Upon receiving the signal from the hybrid camera 3, the electric slider 51 drives the electric telescopic plate 52 to rotate. The rotation of the telescopic plate 52 causes the extension plate 53 to rotate around the telescopic plate 52. Simultaneously, the rotation of the extension plate 53 causes the electric rotating plate 54 to rotate until it reaches a horizontal position. At this point, the rotating arc plate 55 flips the clamped billing card, and the electric slider 51 moves closer to the driver's horizontal level, subsequently delivering the billing card to the driver's window. This significantly reduces manual intervention and improves the efficiency of the toll station. To improve efficiency, when a vehicle passes through the toll station, the hybrid camera 3 identifies the vehicle and selects an appropriate method for issuing cards based on the vehicle size, thereby reducing queuing time for manual card issuance, reducing reliance on manual labor, lowering labor costs, saving human resources, and reducing waiting time, thus improving the driver's experience at the toll station. It also avoids the risk of human error and reduces errors and accidents caused by manual operation. At the same time, the rotation of the electric telescopic plate 52 drives the fixed plate 511 to rotate, which in turn drives the rotating plate 513 to rotate. Simultaneously, the rotation of the rotating plate 513 drives the fixed rod 512 to move, which in turn drives the protective plate 58 to move upward. Under the action of the fixed rod 512, the protective plate 58 moves until it releases the limit on the electric telescopic plate 52. The protective plate 58 can prevent the equipment from being affected by wind, sand, and dust at the toll station, or even causing the system to crash, thereby improving the stability and reliability of the equipment.

[0035] Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, the surface of the protective cover 57 is provided with a protective device for protecting the electric slider 51. The protective device includes a rotating block 61, which is fixedly installed on the surface of the protective cover 57. A protective plate 62 is rotatably installed on the circumferential surface of the rotating block 61. A telescopic spring plate 63 is fixedly installed on the inner wall of the card issuing machine 1. A spring connecting rod 64 is fixedly installed on the surface of the protective cover 57. A second fixing rod 65 is fixedly installed on the surface of the protective plate 58. A telescopic connecting plate 66 is rotatably installed at the end of the second fixing rod 65 away from the protective plate 58. An anti-touch plate 67 is slidably installed on the surface of the card issuing machine 1. The movement of the second fixing rod 65 drives the telescopic connecting plate 66 to move, and the telescopic connecting plate 66 drives the anti-touch plate 67 to move. A third fixing rod 68 is fixedly installed on the surface of the anti-touch plate 67. A second telescopic spring rod 69 is fixedly installed on the surface of the card issuing machine 1. An extension rod 610 is fixedly installed on the surface of the electric telescopic plate 52.

[0036] The spring connecting rod 64 is fixedly connected to the protective plate 62, and the free end of the telescopic spring rod 69 is fixedly connected to the anti-touch plate 67. The anti-touch plate 67 moves upward under the action of the telescopic connecting plate 66 until it releases the limit on the electric telescopic button 41.

[0037] The surface of the protective plate 62 is set as an arc surface. The protective plate 62 contacts the protective plate 58. The free end of the telescopic connecting plate 66 returns to move towards the protective plate 62 until it limits the protective plate 62.

[0038] The circumferential surface of the electric telescopic plate 52 is provided with an anti-clogging device for cleaning the surface of the ventilation plate 2. The anti-clogging device includes a clamping plate 71, which is fixedly installed on the circumferential surface of the extension rod 610. A fixing block 72 is fixedly installed on the surface of the clamping plate 71. A rotating shaft 73 is rotatably passed through the surface of the fixing block 72. A turntable 74 is fixedly installed on the circumferential surface of the rotating shaft 73. A brush cylinder 75 is fixedly installed on the circumferential surface of the rotating shaft 73. The turntable 74 moves and rotates under the action of the card issuing machine 1. At this time, the rotation of the turntable 74 drives the brush cylinder 75 to rotate. A sliding block 76 is slidably installed on the inner wall of the card issuing machine 1. A telescopic spring rod 77 is fixedly installed on the inner wall of the card issuing machine 1.

[0039] The brush cylinder 75 has a brush plate on its circumferential surface. The free end of the telescopic spring rod 77 is fixedly connected to the sliding block 76. The surface of the card plate 71 has a card groove. The movement of the card plate 71 drives the fixed block 72 to move. The movement of the fixed block 72 drives the rotating shaft 73 to move. The inner wall of the card groove is in contact with the sliding block 76.

[0040] In this embodiment, during operation: the protective plate 58 moves upward under the action of the first fixed rod 512, driving the second fixed rod 65 to move. Simultaneously, the movement of the second fixed rod 65 drives the telescopic connecting plate 66 to move. The telescopic connecting plate 66 drives the anti-touch plate 67 to move. The anti-touch plate 67 moves upward under the action of the telescopic connecting plate 66 until it releases the limit on the electric telescopic button 41, preventing card dispensing errors due to accidental touch or misoperation, ensuring the accuracy of each card dispensing process, avoiding unnecessary confusion and delays, reducing accidents or card dispensing failures caused by human error, and ensuring stable system operation. Simultaneously, the electric rotating plate 54 rotates under the action of the extension plate 53. The rotating plate 54 contacts and presses the protective plate 62 to rotate, releasing the limit on the card dispensing block 42. This effectively prevents short circuits or corrosion of electronic components caused by excessive humidity. Moisture can also cause cards to jam, affecting the card dispensing process. The protective plate can... Effectively isolating external moisture reduces the chance of water entering the equipment, thus ensuring that the equipment is not affected by humidity changes, further improving the stability and reliability of the equipment. When the electric rotating plate 54 rotates to a horizontal angle, the telescopic connecting plate 66, after losing the effect of the electric rotating plate 54, moves its free end back towards the protective plate 62 until it limits the protective plate 62. Subsequently, after the card is handed to the driver, the electric rotating plate 54 returns to contact and squeezes the free end of the telescopic spring plate 63, moving it away from the protective plate 62. At this time, the protective plate 62 moves towards the protective cover 57 under the action of the spring connecting rod 64 until it fits against the protective plate 58 and limits the protective cover 57. This can reduce the impact of temperature differences caused by changes in ambient temperature on the card issuing device, help improve the durability of the equipment, extend the service life of the equipment, and reduce failures or damage caused by moisture.

[0041] When the extension rod 610 rotates under the action of the electric telescopic plate 52, it drives the clamping plate 71 to rotate. Simultaneously, the clamping plate 71 rotates towards the ventilation plate 2 until its surface groove engages with the sliding block 76. This improves the stability of the clamping plate 71 during subsequent movements, allowing for more efficient and stable completion of cleaning tasks, reducing failure rates, increasing cleaning efficiency, and making cleaning work more efficient and reliable. This provides a guarantee for the long-term operation of the equipment. Subsequently, when the electric telescopic plate 52 moves under the action of the electric slider 51, it drives the clamping plate 71 to move. Simultaneously, the movement of the clamping plate 71 drives the fixed block 72 to move. The movement of the rotating shaft 73 drives the rotating plate 74 to move. At the same time, the rotating shaft 73 drives the rotating plate 74 to move. Since the rotating plate 74 is in contact with the surface of the card issuing machine 1, the rotating plate 74 rotates under the action of the card issuing machine 1. The rotation of the rotating plate 74 drives the brush cylinder 75 to rotate, and the rotation of the brush cylinder 75 drives the brush plate to rotate, brushing off the dust or impurities attached to or adhering to the surface of the ventilation plate 2. This prevents the ventilation holes from being blocked, which would affect the heat dissipation of the card issuing machine 1 and cause the temperature of the card issuing machine 1 to rise, affecting the normal operation of the equipment. Regularly cleaning the ventilation holes 2 ensures unobstructed ventilation, helps prevent the equipment from overheating, thereby improving the operational stability of the equipment and extending its service life.
