Description

Technical Field

[0001] This invention relates to the field of construction, and more particularly to parking management equipment, specifically a parking barrier lifting device based on smart city construction. Background Technology

[0002] With the acceleration of urbanization and the continuous growth of car ownership, urban traffic congestion has become an increasingly prominent problem. Against this backdrop, smart city construction has become an important direction for improving urban management efficiency and residents' quality of life. As a key node in the urban transportation system, the level of intelligent management of parking lots directly affects the overall operational efficiency of urban traffic. Smart parking systems, by integrating advanced technologies such as the Internet of Things, big data, and artificial intelligence, aim to optimize the allocation of parking resources, improve operational efficiency, and enhance user experience.

[0003] In parking management systems, the entrance / exit barrier gate is one of the most basic and critical pieces of equipment. Traditional parking barrier gates typically use a fixed layout, with one lane for entry and one for exit at each entrance / exit, and one barrier gate for each lane, managing vehicle entry and exit separately. For larger parking lots, multiple independent entrances / exits may be set up on different roads, but at the same entrance / exit on the same road, there are usually still only two lanes, one for entry and one for exit.

[0004] Currently, Chinese utility model patent CN222105994U discloses a "parking fee collection device for restricting excessive vehicle entry." This technical solution includes two camera posts installed on the roadbed, two barriers installed on the two camera posts respectively, and a fee collection post installed on the roadbed. The fee collection post is located to one side of one of the camera posts, and a warning post is fixedly connected to the upper surface of the roadbed, located to the side of the other camera post. A transmission component is internally connected to the warning post, and a support rod is connected to the output end of the transmission component. A display is connected to the end of the support rod away from the transmission component. The device works by using the warning post to control the support rod and display when there are no available parking spaces, thus alerting and blocking external vehicles and preventing continuous entry and congestion within the parking lot.

[0005] However, the aforementioned existing technologies and the parking barrier devices commonly used in the market still have significant technical shortcomings in practical applications. Specifically, in large public places where traffic flow exhibits obvious tidal characteristics, such as large shopping malls, amusement parks, stadiums, and transportation hubs, there will be a concentrated influx or outflow of vehicles during certain time periods. For example, shopping malls see a large number of customers driving to or from the mall around mealtimes; stadiums experience momentary traffic peaks before and after events; and amusement parks experience similar situations during opening and closing times.

[0006] In the above scenario, traditional entrances and exits only have two fixed lanes, one for entry and one for exit. When the number of vehicles in one direction (entering or exiting) increases sharply, that fixed lane becomes a bottleneck, causing severe queuing and congestion. Meanwhile, lanes in the opposite direction are often idle or underutilized, but due to the fixed lane design, these idle lanes cannot be temporarily redeployed to alleviate pressure in the congested direction. This mismatch between lane resources and traffic demand not only severely reduces vehicle throughput and prolongs driver waiting time, but can also cause traffic chaos in the entrance / exit area and even affect the normal operation of surrounding urban roads. Furthermore, prolonged waiting and congestion significantly reduce customer satisfaction and the parking experience. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a parking barrier lifting device based on smart city construction.

[0020] Preferably, the interception mechanism includes a rotating rod and an interception motor; a third motor cavity is provided on one side of the upper end of the moving scanner, and the interception motor is fixedly installed on the inner wall of the third motor cavity; the output shaft of the interception motor is located outside the third motor cavity and is coaxially fixedly connected to the rotating rod, and the rotating rod is fixedly connected to one end of the moving railing.

[0021] Preferably, the indicating mechanism includes a display, a support block, and a warning board; the support block is fixedly connected to the middle of the movable railing, and the two sides of the support block are respectively fixedly connected to the display and the warning board; the display screen of the display is located on the side away from the support block and is used to display the remaining parking space information inside the parking lot; the warning board has a posting area on the side away from the support block for posting payment QR codes or warning slogans.

[0024] This invention provides a parking barrier lifting device based on smart city construction. It offers the following advantages: By adding a tidal flow lane controlled by a mobile scanner and a mobile barrier, along with a moving mechanism, a steering mechanism, and a controller, the dynamic allocation of lane functions on demand is achieved. When entrance traffic surges, the moving mechanism moves the mobile scanner and its components to the entrance side, temporarily setting the middle lane as a second entrance, creating a dual-entrance traffic pattern with the original fixed entrance, nearly doubling the entrance capacity. When exit traffic surges, the moving mechanism moves the aforementioned components to the exit side, temporarily setting the middle lane as a second exit, creating a dual-exit traffic pattern with the original fixed exit, similarly significantly increasing the exit capacity. This breaks the limitations of fixed functions for traditional parking lot entrance and exit lanes, allowing lane resources to be flexibly allocated according to tidal changes in traffic flow. This effectively solves the resource mismatch problem of "entrance congestion while exit is idle" or "exit congestion while entrance is idle" during peak hours, significantly improving overall traffic efficiency, reducing vehicle queuing time, and alleviating traffic pressure in entrance and exit areas.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] Examples, such as Figures 1 to 7As shown, a parking barrier device based on smart city construction includes a floor 1. Four shoulders 2 are fixedly connected at equal intervals along the width direction on the upper surface of the floor 1. The four shoulders 2 are arranged parallel to each other to divide the floor 1 into a first side lane (fixed entrance lane), a middle lane (i.e., a tidal flow lane), and a second side lane (fixed exit lane). Fixed scanners 3 are fixedly installed on the upper surfaces of the two middle shoulders 2. Each fixed scanner 3 has a fixed railing 4 rotatably connected to its side. The two fixed railings 4 are located above the first and second side lanes of the floor 1, respectively, and are used to control the passage of the corresponding fixed lanes (this is prior art, such as the parking fee collection device disclosed in patent CN222105994U which can limit excessive vehicle entry, so it will not be described further).

[0037] The improvement of this invention is as follows: a moving mechanism is installed on one of the middle shoulders 2 (i.e., a shoulder adjacent to the middle lane); the output end of the moving mechanism is connected to a moving scanner 7, and the moving mechanism drives the moving scanner 7 to move back and forth along the extension direction of the middle lane; a steering mechanism is installed on the moving scanner 7, and the output end of the steering mechanism is connected to a camera 8, and the steering mechanism drives the camera 8 to rotate to change the shooting direction; an interception mechanism is installed on the side of the moving scanner 7, and the output end of the interception mechanism is connected to a moving barrier 10, and the interception mechanism drives the moving barrier 10 to rotate in the vertical plane to raise or lower the barrier; an indicator mechanism is installed in the middle of the moving barrier 10, and the moving barrier 10 is located above the middle lane.

[0038] like Figure 4 , Figure 5 and Figure 6 As shown, the upper surface of the shoulder 2 connected to the mobile scanner 7 is provided with a groove 14 and a motor cavity 19 that are interconnected. The axial direction of the groove 14 is consistent with the length direction of the shoulder 2. The moving mechanism is installed inside the groove 14 and the motor cavity 19 to reduce the occupation of external space and reduce the risk of damage from exposure.

[0039] Specifically, the moving mechanism includes a moving motor 22, a lead screw 17, and a slider 25. The moving motor 22 is fixedly installed inside the first motor cavity 19. The output shaft of the moving motor 22 is fixedly connected to one end of the lead screw 17 via a coupling. The other end of the lead screw 17 extends horizontally into the slide groove 14 and is rotatably connected to the inner wall of the slide groove 14 away from the first motor cavity 19 via a bearing. The slider 25 is sleeved on the outside of the lead screw 17, and the slider 25 has an internal thread that matches the external thread of the lead screw 17, forming a lead screw and nut pair. The lower outer wall of the slider 25 slides against the inner wall of the slide groove 14 to restrict the slider 25 from rotating with the lead screw 17. The upper end of the slider 25 extends through the upper opening of the slide groove 14 and extends above the shoulder 2, and is fixedly connected to the bottom surface of the moving scanner 7.

[0040] When the mobile motor 22 starts, its output shaft drives the lead screw 17 to rotate, and through the threaded transmission, the slider 25 moves back and forth along the horizontal direction of the slide groove 14, thereby driving the mobile scanner 7 and the camera 8 and the mobile guardrail 10 installed on it to move as a whole along the extension direction of the middle lane.

[0041] To protect the mobile mechanism from external environmental factors such as rain and dust, this embodiment also incorporates multiple protective structures:

[0042] like Figure 4 As shown, several latching slots 18 are provided on one side of the upper opening of the first motor cavity 19, and a baffle plate 20 is hinged to the other side of the upper opening of the first motor cavity 19. Several mounting blocks 21 are fixedly connected to the free side of the baffle plate 20, and each mounting block 21 is respectively inserted into the corresponding latching slot 18. The length of the latching slot 18 is greater than the length of the mounting block 21, so that the baffle plate 20 still has a margin when it is in the latched state. Therefore, when maintenance is required, the mounting block 21 can be pulled to disengage it from the latching slot 18 through the margin, so as to easily open the baffle plate 20. If necessary, the mounting block 21 can also be fixed to the shoulder 2 by bolts through it to prevent accidental opening. The side wall of the mounting block 21 is movably fitted with the side wall of the latching slot 18 to ensure tight fastening and smooth opening and closing; the moving motor 22 is located below the baffle plate 20.

[0043] like Figure 2 and Figure 3 As shown, ventilation openings 16 are provided on both sides of the slide 14, and ventilation mesh 6 is fixedly connected to the inner wall of each ventilation opening 16. The function is to allow a small amount of rainwater, dust or debris that falls into the slide 14 or the first motor cavity 19 to be discharged through the ventilation openings 16, so as to avoid clogging or corrosion of the moving mechanism.

[0044] like Figure 1 , Figure 5 As shown, the lower ends of the front and rear sides of the mobile scanner 7 are respectively fixedly connected to one end of two U-shaped bellows covers 5. The U-shaped bellows covers 5 are made of stretchable flexible material and have a U-shaped structure. Both U-shaped bellows covers 5 are installed on the upper surface of the road shoulder 2. The other ends of the U-shaped bellows covers 5 are fixedly connected to two detachable blocks 23, which are fixedly connected to the side wall of the road shoulder 2 by bolts. The mobile motor 22, lead screw 17, shielding plate 20 and mounting block 21 are respectively located in the internal space of the two U-shaped bellows covers 5. In addition, the lower ends of the left and right sides of the mobile scanner 7 are fixedly connected to support plates 24, and the two support plates 24 are respectively fixedly connected to the adjacent ends of the two U-shaped bellows covers 5. When the mobile scanner 7 moves, the U-shaped bellows covers 5 can extend and retract accordingly, so that the slide 14 and the first motor cavity 19 can always be covered from below, effectively preventing rainwater and dust from entering.

[0045] like Figure 7As shown, the steering mechanism includes a steering rod 27 and a steering motor 28; a second motor cavity 29 is provided on the upper surface of the moving scanner 7, and the steering motor 28 is fixedly installed on the inner wall of the second motor cavity 29; the output shaft of the steering motor 28 extends upward and is fixedly connected to the lower end of the steering rod 27, and the upper end of the steering rod 27 is fixedly connected to the camera 8; a heat dissipation vent 30 is provided on the side of the second motor cavity 29, and the second motor cavity 29 is connected to the outside through the heat dissipation vent 30 to dissipate the heat generated by the steering motor 28 when it is working.

[0046] When it is necessary to change the shooting direction of camera 8 (for example, switching from shooting vehicles in the entrance direction to shooting vehicles in the exit direction), the controller controls the steering motor 28 to start, and its output shaft drives the steering rod 27 to rotate, thereby driving camera 8 to rotate in the horizontal plane until camera 8 faces the desired direction.

[0047] like Figure 7 As shown, the interception mechanism includes a rotating rod 15 and an interception motor 32; a third motor cavity 31 is provided on one side of the upper end of the moving scanner 7, and the interception motor 32 is fixedly installed on the inner wall of the third motor cavity 31; the output shaft of the interception motor 32 extends horizontally and passes through the outside of the third motor cavity 31, and is coaxially and fixedly connected to one end of the rotating rod 15. The rotating rod 15 is fixedly connected to one end of the moving barrier 10. The moving barrier 10 is horizontally positioned above the middle lane.

[0048] When a vehicle is allowed to pass, the controller activates the blocking motor 32, whose output shaft drives the rotating rod 15 to rotate. The rotating rod 15 then lifts the movable barrier 10 upwards, allowing the vehicle to pass underneath it. After the vehicle has passed, the controller reverses the blocking motor 32, causing the movable barrier 10 to fall back to its original position and resume its blocking state.

[0049] like Figure 6 and Figure 7 As shown, the indicating mechanism includes a display 11, a support block 12, and a warning plate 13; the support block 12 is fixedly connected to the middle of the movable barrier 10, and the two sides of the support block 12 are fixedly connected to the display 11 and the warning plate 13 respectively; the display screen of the display 11 is located on the side away from the support block 12 and is used to display the remaining parking space information inside the parking lot; the warning plate 13 has a posting area 26 on the side away from the support block 12 for posting payment QR codes or warning slogans.

[0050] In practical applications, when the middle lane is designated as an entrance, the movable barrier 10 is lowered, and the side facing the entering vehicles becomes a display 11. The display 11 is connected to the parking lot's central control room via wired or wireless means, displaying the remaining number of parking spaces and directional guidance in real time for each area of ​​the parking lot, helping drivers quickly find parking spaces. When the middle lane is designated as an exit, the movable barrier 10 is lowered, and the side facing the exiting vehicles becomes a warning board 13, allowing drivers to pay online by scanning the QR code on the display area 26.

[0051] like Figure 1 and Figure 6 As shown, a sensor 9 is fixedly connected to the lower end of the mobile scanner 7 near the middle lane. The sensor 9 can be an infrared sensor, an ultrasonic sensor, or a geomagnetic sensor, used to detect in real time whether a vehicle has completely passed under the mobile barrier 10. When the sensor 9 detects that a vehicle has passed, it sends a signal to the controller, which then controls the interceptor motor 32 to lower the mobile barrier 10.

[0052] The signal output terminal of sensor 9 is connected to the signal input terminal of the controller; the control output terminal of the controller is connected to the moving motor 22, the steering motor 28 and the intercepting motor 32 respectively; the control terminal and data output terminal of camera 8 are connected to the controller respectively; the controller controls the moving motor 22 to start according to the change of traffic flow, driving the moving scanner 7 to move; when the moving scanner 7 moves to the position, the controller controls the steering motor 28 to drive the camera 8 to rotate to the corresponding shooting direction, and controls the intercepting motor 32 to drive the moving barrier 10 to perform the raising or lowering action.

[0053] When in use, this device can operate in the following three modes depending on the traffic flow:

[0054] In normal mode (one entry and one exit, normal passage):

[0055] like Figure 1 As shown, when the traffic flow at the parking lot entrance and exit is balanced, and both fixed entrances and exits can meet the passage demand without congestion, the controller sends a stop command to the moving motor 22, and the moving motor 22 stops working. The slider 25 remains stationary, and the moving scanner 7 stays in the middle of the middle lane, without interfering with any fixed lane. The controller also sends a lowering command to the blocking motor 32 (or maintains the current state), and the blocking motor 32 remains locked, keeping the moving barrier 10 horizontal and positioned above the middle lane to effectively prevent vehicles from passing through it. The controller sends a standby command to the steering motor 28, and the camera 8 stops taking pictures or enters sleep mode to reduce energy consumption. Both the display 11 and the camera 8 are turned off or in standby mode.

[0056] At this point, vehicles enter via the first lane (fixed entrance). After the license plate is recognized by the fixed scanner 3, the fixed barrier 4 lifts, allowing the vehicle to enter the parking lot. Vehicles exit via the second lane (fixed exit). After being recognized by another fixed scanner 3 or after payment, the corresponding fixed barrier 4 lifts, allowing the vehicle to exit. In this mode, the tidal flow lane is completely closed, and the device is equivalent to a traditional fixed one-in-one-out system. All moving parts are in standby or stationary state, resulting in minimal energy consumption.

[0057] During peak entry periods (the tidal flow channel becomes the second entrance):

[0058] When the number of vehicles entering a parking lot far exceeds the number of vehicles already in the parking lot during a given time period (e.g., before mealtimes at a shopping mall or during the opening hours of an amusement park), queues and congestion occur at the fixed entrance, while the fixed exit and the middle lane remain empty. At this time, the tidal flow lane function switching command is triggered. This can be done manually by parking lot management personnel via the control panel, or automatically by the parking lot's central control system based on entrance queue length sensors, historical traffic data, or license plate recognition counts. The controller then sends a forward rotation command to the moving motor 22 (the specific rotation direction depends on whether the entrance is on the first or second side). The moving motor 22 starts, and its output shaft drives the lead screw 17 to rotate. Through the transmission action of the lead screw and nut pair, the slider 25 moves smoothly along the slide groove 14 towards the entrance end of the first lane (fixed entrance). This causes the moving scanner 7, camera 8, moving barrier 10, display 11, warning board 13, and sensor 9 on the slider 25 to move synchronously. When the mobile scanner 7 moves to a predetermined position near the fixed scanner 3 on the inlet side, the controller immediately sends a stop command to the mobile motor 22 (the position signal can be detected by a position sensor, such as a limit switch or encoder feedback). The mobile motor 22 stops rotating and remains self-locking, locking the mobile scanner 7 in that position. During this process, the U-shaped bellows cover 5 extends and retracts with the movement of the mobile scanner 7, always maintaining the shielding and protection of the slide 14 and the lead screw 17.

[0059] Subsequently, the controller sends a rotation command to the steering motor 28, which then starts. The output shaft of the steering motor 28 drives the steering rod 27 to rotate, which in turn rotates the camera 8 in the horizontal plane, aligning the lens of the camera 8 towards the entrance (i.e., towards the direction of travel of the entering vehicle). In this embodiment, the controller can send a stop command to the steering motor 28 after confirming that the camera 8 has rotated to the correct position using an angle sensor or limit switch. At this point, the camera 8 is aligned with the license plate of the vehicle preparing to enter the middle lane and enters the recognition state. Additionally, the controller sends an activation command to the mobile scanner 7 and the camera 8, putting them into a continuously operating mode to collect license plate information of entering vehicles in real time. The image recognition module inside the mobile scanner 7 begins operation, preparing to send the recognition results to the controller.

[0060] Additionally, the controller can interact with the parking lot's central control system in real time via wired or wireless communication interfaces to obtain information on the remaining number and distribution of parking spaces in each area of ​​the parking lot. After processing this information, the controller sends it to the display 11 for display. The screen of display 11 faces the direction of entry, clearly displaying the number of remaining parking spaces in each area using arrows and numbers to guide drivers to quickly select a suitable parking area. At this time, the QR code on the sticker area 26 of the warning board 13 (located on the back of display 11, not facing the vehicle) does not function in entry mode and is only used as a backup.

[0061] When a vehicle enters the middle lane and reaches the designated position, camera 8 captures an image of the vehicle's front license plate. The mobile scanner 7 completes license plate recognition and sends the results (license plate number, entry time, etc.) to the controller, while simultaneously uploading them to the parking lot billing system. After successful verification, the controller sends a raise command to the barrier motor 32. The barrier motor 32 starts, and its output shaft drives the rotating rod 15 to rotate clockwise. The rotating rod 15 then lifts the movable barrier 10, opening the middle lane for traffic. Vehicles begin to pass under the movable barrier 10. Once the vehicle has completely passed under the movable barrier 10, the sensor 9 (e.g., an infrared or ultrasonic sensor) located at the lower end of the mobile scanner 7 detects the vehicle's departure and sends this signal to the controller. Upon receiving the signal from sensor 9, the controller, after a brief delay (e.g., 0.5 seconds to ensure the rear of the vehicle passes safely), sends a lower command to the barrier motor 32. The barrier motor 32 reverses, causing the rotating rod 15 to rotate in the opposite direction, and the movable barrier 10 lowers to a horizontal position, awaiting the next vehicle. Repeat the above cycle until no more vehicles enter the middle lane or the system switches to another mode.

[0062] In this mode, the fixed scanner 3 and fixed barrier 4 on the fixed exit side remain in normal working order, allowing vehicles to exit in an orderly manner. The equipment on the fixed entrance side also continues to operate, accepting vehicles simultaneously with the tidal entrance, forming a dual-entrance traffic pattern.

[0063] Peak exit mode (tidal channel becomes the second exit):

[0064] When the number of vehicles exiting far exceeds the number of vehicles entering within the same time period (e.g., before a shopping mall closes or during the end of a sporting event), queues and congestion occur at the fixed exit, while the fixed entrance and middle lanes remain empty. At this time, the tidal flow lane function switching command is triggered, in the same way as the peak entry mode; the controller then sends a reverse rotation command to the moving motor 22 (opposite to the direction of the peak entry mode). The moving motor 22 starts, driving the lead screw 17 to rotate in the opposite direction, and the slider 25 moves the moving scanner 7 smoothly towards the entrance of the second side lane (fixed exit). When the moving scanner 7 moves to the predetermined position near the fixed scanner 3 on the exit side, the controller detects the position signal, stops the moving motor 22, and locks it.

[0065] Subsequently, the controller sends a rotation command to the steering motor 28, driving the camera 8 to rotate in the horizontal plane, so that its lens faces the exit direction (i.e., the direction in which the exiting vehicle is moving). Once in position, the camera 8 stops and enters a waiting-to-recognize state. Since the movable barrier 10 moves to the exit side position along with the movable scanner 7, when the movable barrier 10 is in a horizontal lowered state, the side facing vehicles entering the middle lane is the warning board 13, not the display 11. Therefore, the controller can control the display 11 to turn off or display auxiliary information such as "Exit Lane". The warning board 13 has a pre-attached online payment QR code (standard for parking lot payment) on its affixing area 26 for drivers to scan and pay.

[0066] When a vehicle enters the middle lane and reaches the designated location, the driver scans the QR code on the warning board 13 with their mobile phone to access the payment page. After the driver completes the online payment, the parking fee system sends a "payment successful" signal to the controller. Upon receiving the payment success signal, the controller simultaneously activates camera 8 or mobile scanner 7 to perform secondary verification of the vehicle's license plate (optional, to prevent accidental release). After successful verification, it sends a gate-raising command to the blocking motor 32. The blocking motor 32 activates, causing the mobile barrier 10 to lift upwards, opening the middle lane for traffic. Vehicles begin to exit from under the mobile barrier 10. Once sensor 9 detects that the vehicle has completely passed, it sends a signal to the controller. The controller then controls the blocking motor 32 to reverse, causing the mobile barrier 10 to fall back to its original position, awaiting the next vehicle. This cycle repeats until no more vehicles enter the middle lane or the system switches to another mode.

[0067] In this mode, the equipment on the fixed entrance side continues to operate, allowing vehicles to enter in an orderly manner, and operates simultaneously with the tidal exit, forming a dual-exit traffic pattern.

[0068] Once the peak period ends and traffic flow returns to normal, the controller can automatically or manually restore the device to normal mode. At this time, the controller can control the moving motor 22 to move the moving scanner 7 back to its initial position in the center of the middle lane. The controller controls the steering motor 28 to reset the camera 8 to the center position or turn it off. The controller controls the blocking motor 32 to lower the moving barrier 10, closing the middle lane. The display 11 and warning panel 13 reset along with the moving barrier 10. The entire system returns to its initial one-in-one-out state.

[0069] This invention adds a movable, controllable tidal flow lane between the entrance and exit of a traditional parking lot. Combined with a moving mechanism, a steering mechanism, a blocking mechanism, and a guiding mechanism, it achieves dynamic, on-demand allocation of lane functions. During peak entry times, the middle lane can be converted into an entrance, and during peak exit times, it can be converted into an exit. This breaks the limitations of fixed lane patterns, significantly improves vehicle throughput, alleviates traffic congestion in the entrance and exit areas, and optimizes the driver's parking and payment experience through the integrated design of displays and warning boards.
