Description

A single-lane bidirectional identification barrier gate integrated machine and barrier gate control system Technical Field

[0001] This utility model relates to the field of barrier gate control technology, and in particular to a single-lane bidirectional identification barrier gate integrated machine and barrier gate control system. Background Technology

[0002] Currently, parking lots and / or residential communities have gates at their entrances and exits to control vehicle access, enabling various entry and exit scenarios, including single-lane traffic. In single-lane traffic scenarios, due to the narrow lane, only one vehicle is allowed to pass at a time, and the entrance and exit are both in the same lane, creating a demand for two-way traffic. Therefore, how to meet this demand becomes an urgent problem to solve.

[0003] To address the need for two-way traffic in a single lane, existing barrier gate control systems employ a solution of installing one barrier gate and two license plate recognition controllers on each lane. The two controllers are installed on opposite sides of the barrier gate, each responsible for recognizing the license plates of vehicles entering or exiting from its respective side. This approach, requiring two license plate recognition controllers, is complex and costly. Summary of the Invention

[0004] The present invention aims to provide a single-lane bidirectional identification barrier gate integrated machine and barrier gate control system, which can solve the problems of complex control and high cost of existing barrier gate control systems when meeting the bidirectional passage requirements of a single lane.

[0005] To solve the above-mentioned technical problems, the first aspect of this utility model provides a single-lane bidirectional recognition barrier gate integrated machine, including: a barrier gate box, a control unit, a barrier gate arm, a drive unit, a first license plate recognition module, and a second license plate recognition module;

[0006] The barrier gate housing includes a first side and a second side, the first side and the second side being inclined and arranged on both sides along the central axis of the barrier gate housing;

[0007] The first license plate recognition module is disposed on the first side and is used to acquire and recognize the license plate number of a vehicle entering the single lane.

[0008] The second license plate recognition module is installed on the second side and is used to acquire and recognize the license plate numbers of vehicles exiting the single lane.

[0009] The control unit is located inside the barrier gate housing and is communicatively connected to the first license plate recognition module, the second license plate recognition module, and the drive unit, respectively. It is used to receive the license plate number output by the first license plate recognition module or the second license plate recognition module and output a drive control signal to the drive unit.

[0010] The barrier arm is mounted on the barrier box, and the drive unit is mounted inside the barrier box, used to drive the barrier arm to rise or fall according to the drive control signal output by the control unit.

[0011] Optionally, the first side is offset from the central axis of the barrier gate housing by a first offset angle, and the second side is offset from the central axis of the barrier gate housing by a second offset angle, wherein both the first offset angle and the second offset angle are acute angles.

[0012] Optionally, the first side and the second side are arranged adjacent to each other, or the first side and the second side are arranged with one side separated from each other.

[0013] Optionally, the first side includes a first mounting hole for mounting the first license plate recognition module; the second side includes a second mounting hole for mounting the second license plate recognition module.

[0014] Optionally, the single-lane bidirectional identification barrier gate integrated machine further includes a first supplementary light and a second supplementary light, which are respectively disposed on the first side and the second side.

[0015] Optionally, the first side includes a third mounting hole, in which the first supplementary light is disposed; the second side includes a fourth mounting hole, in which the second supplementary light is disposed.

[0016] Optionally, the single-lane bidirectional recognition barrier gate also includes a first display screen and a second display screen, which are respectively disposed on the first side and the second side and are respectively communicatively connected to the control unit.

[0017] Optionally, the first side includes a fifth mounting hole, in which the first display screen is disposed; the second side includes a sixth mounting hole, in which the second display screen is disposed.

[0018] Optionally, the single-lane bidirectional identification barrier gate further includes a first sensing module and a second sensing module. The first sensing module and the second sensing module are respectively installed on the single lane and are respectively connected to the control unit for sensing whether there are vehicles entering or exiting the single lane. When a vehicle is sensed to be entering or exiting the single lane, a sensing signal is generated and the sensing signal is transmitted to the control unit.

[0019] Accordingly, a second aspect of this utility model provides a barrier gate control system, including the single-lane bidirectional identification barrier gate integrated machine and server described in the first aspect of this utility model; wherein:

[0020] The single-lane bidirectional recognition barrier gate is connected to the server to obtain and display parking information of vehicles entering and exiting the vehicle.

[0021] Compared to existing technologies, this utility model provides a single-lane bidirectional recognition barrier gate integrated machine and barrier gate control system. The single-lane bidirectional recognition barrier gate integrated machine includes a barrier gate housing, a control unit, a barrier gate arm, a drive unit, a first license plate recognition module, and a second license plate recognition module. By setting a first side and a second side on the barrier gate housing at an angle along both sides of the central axis of the barrier gate housing, when the barrier gate housing is installed on the side of a single lane, the first side and the second side face the single lane entry direction and the single lane exit direction, respectively. The first license plate recognition module and the second license plate recognition module are respectively set on the first side and the second side, so that the license plate numbers of vehicles entering and exiting the single lane can be acquired and recognized respectively. The same control unit receives the license plate numbers output by the first license plate recognition module or the second license plate recognition module, and outputs a drive control signal to the drive unit, so that the drive unit drives the barrier gate arm set on the barrier gate housing to raise or lower according to the drive control signal output by the control unit. This allows the integrated single-lane two-way recognition barrier gate to combine one barrier gate arm and two license plate recognition modules, enabling control of vehicle entry and exit in a single lane. Compared to existing barrier gate control systems that require two license plate recognition controllers, this solution offers higher integration, simpler control, and lower cost, meeting the requirements for two-way recognition and passage in a single lane. It also solves the problem of complex and costly control in existing barrier gate control systems when meeting the needs of two-way passage in a single lane. Attached Figure Description

[0041] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0042] In one embodiment, as shown in FIG1, the present invention provides a single-lane bidirectional recognition barrier gate integrated machine 10, including: barrier gate box 13, control unit (not shown), barrier gate arm 14, drive unit (not shown), first license plate recognition module 11 and second license plate recognition module 12.

[0043] The barrier gate box 13 includes a first side 131 and a second side 132. The first side 131 and the second side 132 are inclined and are arranged on both sides of the central axis L of the barrier gate box 13, so that when the barrier gate box 13 is installed on the side of a single lane, the first side 131 and the second side 132 face the single lane entry direction and the single lane exit direction, respectively.

[0044] The first license plate recognition module 11 is disposed on the first side 131 and is used to acquire and recognize the license plate number of a vehicle entering the single lane.

[0045] The second license plate recognition module 12 is installed on the second side 132 and is used to acquire and recognize the license plate number of vehicles exiting the single lane.

[0046] The control unit is installed inside the barrier gate housing 13 and is communicatively connected to the first license plate recognition module 11, the second license plate recognition module 12 and the drive unit, respectively. It is used to receive the license plate number output by the first license plate recognition module 11 or the second license plate recognition module 12 and output drive control signals to the drive unit.

[0047] The barrier arm 14 is mounted on the barrier box 13, and the drive unit is mounted inside the barrier box 13. It is used to drive the barrier arm 14 to rise or fall according to the drive control signal output by the control unit.

[0048] In this embodiment, a single-lane bidirectional recognition barrier gate integrated machine is provided, including a barrier gate housing, a control unit, a barrier gate arm, a drive unit, a first license plate recognition module, and a second license plate recognition module. A first side and a second side are arranged on the barrier gate housing at an angle along both sides of the central axis of the barrier gate housing, such that when the barrier gate housing is installed on the side of a single lane, the first side and the second side face the single lane entry direction and the single lane exit direction, respectively. The first license plate recognition module and the second license plate recognition module are respectively installed on the first side and the second side, thereby enabling the acquisition and recognition of the license plate numbers of vehicles entering and exiting the single lane. The same control unit receives the license plate numbers output by the first license plate recognition module or the second license plate recognition module, and outputs a drive control signal to the drive unit, causing the drive unit to drive the barrier gate arm installed on the barrier gate housing to rise or fall according to the drive control signal output by the control unit. This allows the integrated single-lane two-way recognition barrier gate to combine one barrier gate arm and two license plate recognition modules, enabling control of vehicle entry and exit in a single lane. Compared to existing barrier gate control systems that require two license plate recognition controllers, this solution offers higher integration, simpler control, and lower cost, meeting the requirements for two-way recognition and passage in a single lane. It also solves the problem of complex and costly control in existing barrier gate control systems when meeting the needs of two-way passage in a single lane.

[0049] In one embodiment, the barrier gate housing 13 includes a first side 131 and a second side 132. The first side 131 and the second side 132 are inclined and arranged on both sides of the central axis L of the barrier gate housing 13, such that when the barrier gate housing 13 is installed on the side of a single lane, the first side 131 and the second side 132 face the single lane entry direction and the single lane exit direction, respectively.

[0050] Specifically, as shown in Figures 1 and 2, the barrier gate box 13 is a square columnar body, including a first side 131 and a second side 132. The first side 131 and the second side 132 are inclined surfaces and are arranged on both sides of the central axis L of the barrier gate box 13.

[0051] The first side 131 is offset from the central axis L of the barrier gate box 13 by a first offset angle a1. The first offset angle a1 is an acute angle and ranges from 30 degrees to 75 degrees, so that the first side 131 is inclined and so that when the barrier gate box 13 is installed on the side of a single lane, the first side 131 faces the direction of entry of the single lane.

[0052] The second side 132 is offset from the central axis L of the barrier gate box 13 by a second offset angle a2. The second offset angle a2 is an acute angle and ranges from 30 degrees to 75 degrees, so that the second side 132 is inclined, so that when the barrier gate box 13 is installed on the side of the single lane, the second side 132 faces the exit direction of the single lane.

[0053] For example, the first side 131 and the second side 132 are inclined and symmetrically arranged on both sides of the central axis L of the barrier gate box 13. The first side 131 is offset from the central axis L of the barrier gate box 13 by a first offset angle a1, and the second side 132 is offset from the central axis L of the barrier gate box 13 by a second offset angle a2. The first offset angle a1 and the second offset angle a2 are equal. For example, the first offset angle a1 and the second offset angle a2 are both 45 degrees.

[0054] For example, the first side 131 and the second side 132 can be arranged adjacent to each other, so that the first side 131 and the second side 132 can form an outwardly convex cone shape.

[0055] The first side 131 and the second side 132 can also be separated by one side, so that the first side 131, the second side 132 and the side between the first side 131 and the second side 132 form an outwardly protruding platform shape.

[0056] The first side 131 includes a first mounting hole 1311, the shape of which matches the first license plate recognition module 11, for mounting the first license plate recognition module 11.

[0057] The second side 132 includes a second mounting hole 1322, the shape of which matches the shape of the second license plate recognition module 12, and the second mounting hole 1322 is used to install the second license plate recognition module 12.

[0058] In one embodiment, the barrier arm 14 is disposed on the barrier box 13. Specifically, the barrier arm 14 may be disposed on the side of the barrier box 13 near the first side 131, or it may be disposed on the side of the barrier box 13 near the second side 132.

[0059] When the barrier gate housing 13 is installed on one side of a single lane, the barrier gate arm 14 is lowered by the drive unit. The installation height of the barrier gate arm 14 in the barrier gate housing 13 and the length of the barrier gate arm 14 are sufficient to prevent vehicles from passing through the single lane.

[0060] When the barrier gate arm 14 is installed on the side of the barrier gate housing 13 near the first side 131 or near the second side 132, the first side 131 and the second side 132 are respectively radially oriented towards the single lane entry direction and the single lane exit direction. Specifically, when the barrier gate arm 14 is lowered, the first side 131 is oriented towards the single lane entry direction on the first side of the barrier gate arm 14, and the second side 132 is oriented towards the single lane exit direction on the second side of the barrier gate arm 14.

[0061] In one embodiment, the first license plate recognition module 11 and the second license plate recognition module 12 are respectively disposed on the first side 131 and the second side 132, and are respectively used to acquire and recognize the license plate numbers of vehicles entering the single lane and exiting the single lane.

[0062] Specifically, as shown in Figure 1, the first license plate recognition module 11 is installed in the first mounting hole 1311 on the first side 131, facing the single lane entry direction. The first license plate recognition module 11 is communicatively connected to the control unit and is used to acquire and recognize the license plate number of the vehicle entering the single lane entry direction based on the photo control signal output by the control unit.

[0063] The second license plate recognition module 12 is installed in the second mounting hole 1322 on the second side 132, facing the exit direction of the single lane. The second license plate recognition module 12 is connected to the control unit and is used to acquire and recognize the license plate number of the vehicle leaving the single lane based on the photo control signal output by the control unit.

[0064] Since the first side 131 and the second side 132 have different orientations, when the barrier gate box 13 is installed on one side of a single lane, the first side 131 and the second side 132 are radially oriented towards the single lane's entry direction and exit direction, respectively. Therefore, the first license plate recognition module 11 and the second license plate recognition module 12 are respectively set on the first side 131 and the second side 132. The first license plate recognition module 11 and the second license plate recognition module 12 are also radially oriented towards the single lane's entry direction and exit direction, and the coverage areas of the first license plate recognition module 11 and the second license plate recognition module 12 do not overlap.

[0065] The first side 131 faces the single-lane entry direction on the first side of the barrier gate 14. The first license plate recognition module 11 installed in the first side 131 also faces the single-lane entry direction on the first side of the barrier gate 14. The capture angle of the first license plate recognition module 11 can cover the entire lateral direction of the single lane. Furthermore, since the single lane for vehicles to enter and exit is relatively narrow, the vehicles entering and exiting will not be too far from the installation position of the single-lane bidirectional recognition barrier gate integrated machine 10. The capture height of the first license plate recognition module 11 can be adjusted according to the height of the vehicle's license plate position, so that the capture angle of the first license plate recognition module 11 can cover the vehicle's license plate position, ensuring that the vehicle's license plate position is within the capture angle of the first license plate recognition module 11.

[0066] Similarly, the second side 132 faces the exit direction of the single lane on the second side of the barrier gate 14, and the second license plate recognition module 12 installed in the second side 132 also faces the exit direction of the single lane on the second side of the barrier gate 14. The capture angle of the second license plate recognition module 12 can cover the entire lateral direction of the single lane, and the capture height of the second license plate recognition module 12 can be adjusted according to the height of the vehicle's license plate position so that the capture angle of the second license plate recognition module 12 can cover the vehicle's license plate position, ensuring that the vehicle's license plate position is within the capture angle of the second license plate recognition module 12.

[0067] For example, the first license plate recognition module 11 and the second license plate recognition module 12 can be license plate recognition cameras.

[0068] In one embodiment, as shown in FIG1, the single-lane bidirectional recognition barrier gate integrated machine 10 further includes a first supplementary light 15 and a second supplementary light 16. The first supplementary light 15 and the second supplementary light 16 are respectively disposed on the first side 131 and the second side 132, providing auxiliary light sources for the first license plate recognition module 11 and the second license plate recognition module 12, respectively.

[0069] Specifically, the first side 131 includes a third mounting hole 1313, the shape of which matches the first auxiliary light 15. The first auxiliary light 15 is disposed in the third mounting hole 1313 and is used in conjunction with the first license plate recognition module 11 to provide an auxiliary light source for the first license plate recognition module 11.

[0070] The second side 132 includes a fourth mounting hole 1324. The shape of the fourth mounting hole 1324 matches the second auxiliary light 16. The second auxiliary light 16 is disposed in the fourth mounting hole 1324. The second auxiliary light 16 is used in conjunction with the second license plate recognition module 12 to provide an auxiliary light source for the second license plate recognition module 12.

[0071] In one embodiment, as shown in FIG1, the single-lane bidirectional recognition barrier gate integrated machine 10 further includes a first display screen 17 and a second display screen 18. The first display screen 17 and the second display screen 18 are respectively disposed on the first side 131 and the second side 132, and are respectively connected to the control unit for displaying the vehicle passage status according to the display control signal of the control unit to notify the user.

[0072] Specifically, the first side 131 includes a fifth mounting hole 1315, the shape of which matches the first display screen 17. The first display screen 17 is disposed in the fifth mounting hole 1315 and is communicatively connected to the control unit to display the vehicle traffic status according to the first display control signal of the control unit to notify the user.

[0073] The second side 132 includes a sixth mounting hole 1326, the shape of which matches the second display screen 18. The second display screen 18 is disposed in the sixth mounting hole 1326 and is communicatively connected to the control unit. It is used to display the vehicle traffic status according to the second display control signal of the control unit to notify the user.

[0074] For example, if the first license plate recognition module 11 first recognizes the license plate number of a vehicle entering or exiting a single lane, the control unit outputs a first display control signal to the first display screen 17, and the first display screen 17 displays the word "Pass". The control unit outputs a second display control signal to the second display screen 18, and the second display screen 18 displays the word "Please Exit" to notify the user.

[0075] If the second license plate recognition module 12 first recognizes the license plate number of a vehicle entering or exiting a single lane, the control unit outputs a second display control signal to the second display screen 18, which displays the word "Pass". The control unit outputs a first display control signal to the first display screen 17, which displays the word "Please Exit" to notify the user.

[0076] The positions of the first mounting hole 1311, the third mounting hole 1313, and the fifth mounting hole 1315 on the first side 131 can be determined according to the length or width of the first side 131. The first mounting hole 1311, the fifth mounting hole 1315, and the third mounting hole 1313 can be arranged sequentially from top to bottom along the first side 131. Alternatively, the first mounting hole 1311 and the third mounting hole 1313 can be arranged side by side, and the fifth mounting hole 1315 can be arranged separately above or below the first mounting hole 1311 and the third mounting hole 1313.

[0077] Similarly, the positions of the second mounting hole 1322, the fourth mounting hole 1324, and the sixth mounting hole 1326 on the second side 132 can be determined according to the length or width of the second side 132. The second mounting hole 1322, the sixth mounting hole 1326, and the fourth mounting hole 1324 can be arranged sequentially from top to bottom along the first side 131. Alternatively, the second mounting hole 1322 and the fourth mounting hole 1324 can be arranged side by side, and the sixth mounting hole 1326 can be set separately above or below the second mounting hole 1322 and the fourth mounting hole 1324.

[0078] In one embodiment, as shown in Figure 3, the single-lane bidirectional identification barrier gate 10 further includes a first sensing module 191 and a second sensing module 192. The first sensing module 191 and the second sensing module 192 are respectively installed on the single lane and are respectively connected to the control unit for sensing whether there are vehicles entering or exiting the single lane. When a vehicle is sensed to be entering or exiting the single lane, a sensing signal is generated and transmitted to the control unit so that the control unit can output a photo-taking control signal after receiving the sensing signal.

[0079] Specifically, the barrier gate housing 13 is installed on one side of the single lane, and the first sensing module 191 is installed on the passage of the first single lane of the barrier gate arm 14. The first sensing module 191 is communicatively connected to the control unit and is used to sense whether there are vehicles entering or exiting the passage of the first single lane of the barrier gate arm 14. When a vehicle is sensed to be entering or exiting the single lane, a first sensing signal is generated and transmitted to the control unit, so that after receiving the first sensing signal, the control unit outputs a first photo capture control signal to the first license plate recognition module 11 to obtain and recognize the license plate number of the vehicle entering or exiting the first single lane of the barrier gate arm.

[0080] The second sensing module 192 is installed on the passage of the second single lane on the second side of the barrier gate 14. The second sensing module 192 is communicatively connected to the control unit and is used to sense whether there are vehicles entering or exiting the passage of the second single lane on the second side of the barrier gate 14. When a vehicle is sensed to be entering or exiting the single lane, a second sensing signal is generated and transmitted to the control unit. After receiving the second sensing signal, the control unit outputs a second photo capture control signal to the second license plate recognition module 12 to obtain and recognize the license plate number of the vehicle entering or exiting the second single lane on the second side of the barrier gate.

[0081] The first sensing module 191, the control unit, and the first license plate recognition module 11, the first display screen 17, and the first supplementary light 15 disposed on the first side 131 form a first single-lane recognition channel to recognize the license plate numbers of vehicles in the first single lane of the access gate 14. The second sensing module 192, the control unit, and the second license plate recognition module 12, the second display screen 18, and the second supplementary light 16 disposed on the second side 132 form a second single-lane recognition channel to recognize the license plate numbers of vehicles in the second single lane of the access gate 14. The first single-lane recognition channel and the second single-lane recognition channel form a bidirectional recognition channel, thereby achieving the purpose of bidirectional recognition of a single lane.

[0082] For example, the first sensing module 191 and the second sensing module 192 can be buried coil vehicle sensors. By burying a magnetic coil at a fixed distance on the ground, such as the distance of two car lengths, the vehicle can be sensed when the magnetic coil is cut when a vehicle enters the area.

[0083] The first sensing module 191 and the second sensing module 192 can be pulse-type ground vehicle sensors. They send pulse waves to a fixed area and determine whether there is an approaching vehicle based on whether the returned pulse wave is a fixed frequency corresponding to a car.

[0084] In one embodiment, the control unit is located inside the barrier gate housing 13 and is communicatively connected to the first license plate recognition module 11, the second license plate recognition module 12, and the drive unit, respectively. It is used to receive the license plate number output by the first license plate recognition module 11 or the second license plate recognition module 12 and output drive control signals to the drive unit.

[0085] Specifically, if the control unit receives the first sensing signal output by the first sensing module 191, outputs the first image capture control signal to the first license plate recognition module 11 to acquire and recognize the license plate number of the vehicle entering and exiting the first single lane of the barrier gate 14, and receives the license plate number output by the first license plate recognition module 11, outputs the drive control signal to the drive unit, so that the drive unit drives the barrier gate 14 installed on the barrier gate box 13 to lift or lower according to the drive control signal.

[0086] If the control unit receives the second sensing signal output by the second sensing module 192, it outputs a second photo capture control signal to the second license plate recognition module 12 to acquire and recognize the license plate number of the vehicle entering or exiting the second side single lane of the barrier gate 14, and receives the license plate number output by the second license plate recognition module 12, it outputs a drive control signal to the drive unit so that the drive unit drives the barrier gate 14 installed on the barrier gate box 13 to lift or lower according to the drive control signal.

[0087] Since the barrier gate housing 13 is installed on one side of a single lane, and the single lane for vehicle entry and exit is relatively narrow, the first license plate recognition module 11 and the second license plate recognition module 12 are respectively set on the first side 131 and the second side 132 of the same barrier gate housing 13. The front and rear of the vehicle are equipped with license plate numbers. When a vehicle travels on a single lane and passes through the barrier gate, the first license plate recognition module 11 will first recognize the license plate number on the front of the vehicle. The control unit will output a drive control signal to the drive unit so that the drive unit drives the barrier gate arm 14 set on the barrier gate housing 13 to open (raise) the barrier. After the vehicle passes through the barrier gate, the control unit will output a drive control signal to the drive unit so that the drive unit drives the barrier gate arm 14 set on the barrier gate housing 13 to close (lower) the barrier. However, after a vehicle passes through the barrier gate, the second license plate recognition module 12 will recognize the license plate number at the rear of the vehicle. If no control is applied at this time, the control unit will output a drive control signal to the drive unit again, so that the drive unit will drive the barrier gate arm 14 set on the barrier gate box 13 to open (lift) the barrier gate again according to the drive control signal, resulting in the barrier gate arm 14 opening (lifting) even when no vehicle is entering or exiting the barrier gate.

[0088] To avoid the aforementioned situation, the control unit is also configured to: initiate a preset timer when the vehicle's license plate number is received for the first time; within the preset timer period, if the vehicle's license plate number is received a second time, the control unit compares the first and second received license plate numbers; if the two license plate numbers are determined to be the same, the second received license plate number is deemed invalid, and no processing or drive control signal is output to the drive unit; after the preset timer period expires, the control unit resumes normal processing. This ensures that the license plate number of the front of the vehicle recognized the first time is valid, while the license plate number of the rear of the vehicle recognized the second time is invalid, thus preventing the aforementioned situation from occurring.

[0089] For example, the first license plate recognition module 11 installed on the first side of the barrier gate 14 first recognizes the license plate number of the front of the vehicle. The control unit receives the license plate number from the first license plate recognition module 11 for the first time and starts a timer. Within the preset time, after the vehicle passes through the barrier gate, the second license plate recognition module 12 installed on the second side of the barrier gate 14 recognizes the license plate number of the rear of the vehicle. The control unit receives the license plate number from the second license plate recognition module 12 for the second time. The logic judgment module compares the first and second received license plate numbers. If the first and second received license plate numbers are the same, the second received license plate number is deemed invalid. The control unit does not process the second received license plate number and does not output a drive control signal to the drive unit. This ensures that the first recognized license plate number is valid, while the second recognized license plate number is invalid, thus avoiding the aforementioned situation.

[0090] Understandably, a control unit is an integrated circuit chip with signal processing capabilities. For example, a control unit can be a general-purpose processor, a DSP (Digital Signal Processor), an FPGA (Field Programmable Gate Array), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc.; a general-purpose processor can be a microprocessor, an MCU (Microcontroller Unit), or any conventional processor, etc.

[0091] The present invention provides a single-lane bidirectional identification barrier gate integrated machine 10, the specific usage process of which is as follows:

[0092] Assuming that the first sensing module 191 installed on the single-lane passage first senses that a vehicle is passing through the single lane, the first sensing module 191 generates a first sensing signal and transmits the first sensing signal to the control unit; after receiving the first sensing signal, the control unit outputs a first photo capture control signal to the first license plate recognition module 11. After receiving the first photo capture control signal, the first license plate recognition module 11 acquires and identifies the license plate number of the vehicle entering or exiting the first single lane of the barrier gate 14 and transmits it to the control unit; after receiving the license plate number output by the first license plate recognition module 11, the control unit outputs a drive control signal to the drive unit, so that the drive unit drives the barrier gate 14 to lift and open the gate to allow passage according to the drive control signal. At the same time, the controller starts a timer, and the control unit outputs a first display control signal to the first display screen 17, which displays the word "Pass". The control unit outputs a second display control signal to the second display screen 18, which displays the word "Please Exit" to notify the user. Within the preset timeout period, the second license plate recognition module 12 acquires and recognizes the license plate number of the rear of a vehicle entering or exiting the second lane of the barrier gate 14, and transmits it to the control unit. After receiving the license plate number from the rear of the vehicle from the second license plate recognition module 12, the control unit's logic judgment module compares the received license plate number from the front of the vehicle with the received license plate number from the rear of the vehicle. If the received license plate number from the front of the vehicle and the received license plate number from the rear of the vehicle are the same, the received license plate number from the rear of the vehicle is deemed invalid, and the control unit does not process the received license plate number from the rear of the vehicle and does not output a drive control signal to the drive unit. After the preset timeout period, the control unit resumes normal processing. Thus, the single-lane bidirectional recognition barrier gate integrated machine 10 integrates one barrier gate and two license plate recognition modules to control the entry and exit of vehicles in a single lane. Compared with the existing barrier gate control system, which requires two license plate recognition controllers, this solution has high integration, simple control, and low cost, and can meet the requirements of bidirectional recognition passage in a single lane.

[0093] Based on the same concept, as shown in Figure 4, this utility model provides a barrier gate control system 100, including a single-lane bidirectional identification barrier gate integrated machine 10 and a server 20 as described in any of the above embodiments; wherein:

[0094] The single-lane bidirectional recognition barrier gate 10 is connected to the server 20 to obtain and display parking information of vehicles entering and exiting the vehicle. The parking information of the vehicles entering and exiting the vehicle includes at least one of the following: parking duration and parking fee.

[0095] In this embodiment, the single-lane bidirectional recognition barrier gate integrated machine 10 is the same as the single-lane bidirectional recognition barrier gate integrated machine 10 described in any of the above embodiments. The specific structure and function can be referred to the single-lane bidirectional recognition barrier gate integrated machine 10 described in any of the above embodiments, and will not be repeated here.

[0096] In this embodiment, a barrier gate control system is provided, including a single-lane bidirectional recognition barrier gate integrated machine and a server. The single-lane bidirectional recognition barrier gate integrated machine is communicatively connected to the server to obtain and display parking information of vehicles entering and exiting the lane. The single-lane bidirectional recognition barrier gate integrated machine includes a barrier gate housing, a control unit, a barrier gate arm, a drive unit, a first license plate recognition module, and a second license plate recognition module. A first side and a second side are arranged on the barrier gate housing at an angle along both sides of the central axis of the barrier gate housing, so that when the barrier gate housing is installed on the side of a single lane, the first side and the second side face the single lane entry direction and the single lane exit direction, respectively. The first license plate recognition module and the second license plate recognition module are respectively installed on the first side and the second side, thereby enabling the acquisition and recognition of the license plate numbers of vehicles entering and exiting the single lane. The same control unit receives the license plate numbers output by the first license plate recognition module or the second license plate recognition module, and outputs a drive control signal to the drive unit, causing the drive unit to drive the barrier gate arm installed on the barrier gate housing to rise or fall according to the drive control signal output by the control unit. This allows the integrated single-lane two-way recognition barrier gate to combine one barrier gate arm and two license plate recognition modules, enabling control of vehicle entry and exit in a single lane. Compared to existing barrier gate control systems that require two license plate recognition controllers, this solution offers higher integration, simpler control, and lower cost, meeting the requirements for two-way recognition and passage in a single lane. It also solves the problem of complex and costly control in existing barrier gate control systems when meeting the needs of two-way passage in a single lane.
