Description

Technical Field

[0001] This utility model relates to the technical field of toll collection at one or more management points, and in particular to a lane layout for an ETC bus lane. Background Technology

[0002] The efficiency of the ETC (Electronic Toll Collection) system directly affects the congestion at toll stations and the user's travel experience. As the proportion of ETC vehicles continues to increase, the requirements for the efficiency and reliability of ETC lanes are also increasing.

[0003] Existing optimization solutions for ETC bus lane systems mainly focus on several aspects. Firstly, addressing congestion issues caused by slow pre-transaction processing speeds and insufficient lane depth utilization in traditional ETC lane systems, an improvement solution has emerged: deploying a dual-ETC antenna system in the lane. This system prioritizes transactions and raises the barrier via the front antenna, while the rear antenna provides supplementary correction, effectively improving the one-time pass rate and speed for ETC vehicles.

[0004] A search revealed that patent CN205665742U discloses a toll collection device with dual antennas; Chinese patent CN220962475U discloses a dual-antenna toll collection device for ETC lanes. Existing dual-antenna channels may experience antenna signal interference between the two antennas; the existing dual antennas have a 45° angle with the vertical plane, which can lead to dead zones for the rear antenna. Utility Model Content

[0005] To address the technical problems existing in the background art, this utility model proposes a lane layout for ETC bus-only lanes.

[0006] This utility model proposes a lane layout for ETC bus-only lanes, used for toll collection in dedicated bus lanes. The lane has toll islands on both sides, and a front antenna and a rear antenna are installed above the lane. The front antenna and the rear antenna are connected to the central control system. The toll islands are equipped with barrier gates, which are connected to the central control system. Unlike existing technologies, the power of the rear antenna is lower than that of the front antenna.

[0007] The passage is equipped with a second trigger coil connected to the central control system, and the front antenna is located in front of the second trigger coil, that is, the front antenna is far away from the barrier gate relative to the second trigger coil;

[0008] It also includes a rear trigger coil, which is connected to the central control system. The rear trigger coil is located behind the second trigger coil and is used to detect whether a vehicle passes by. If a vehicle passes the second trigger coil but the vehicle has not completed a toll transaction, the central control system controls the rear trigger coil to open. If the rear trigger coil detects that a vehicle has passed by, it transmits the information to the central control system, and the central control system controls the rear antenna to open.

[0009] The front antenna is normally open, while the rear antenna is triggered to open. By setting the rear and front antennas, when there are many vehicles, both antennas (the rear and front antennas) participate in ETC toll collection, improving toll collection efficiency. When there are few vehicles, by turning off the rear trigger coil, only the front antenna participates in ETC toll collection. Staff can adjust this according to the actual situation.

[0010] Meanwhile, the power of the rear antenna is less than that of the front antenna, and the rear antenna is triggered to turn on by the rear trigger coil, which can avoid interference from the rear antenna when the front antenna is working; and the setting of the second trigger coil and the rear coil can detect whether there is a queuing abnormality. If the second trigger coil and the rear coil continuously detect vehicles, the queuing is abnormal.

[0011] As a further optimization of this utility model, the channel is also provided with a first trigger coil connected to the central control system, and the front antenna is located between the first trigger coil and the second trigger coil. The arrangement of the first trigger coil and the second trigger coil can realize the detection of the vehicle's driving direction.

[0012] As a further optimization of this utility model, the rear antenna is located behind the barrier gate, and the distance between the rear antenna and the barrier gate is 1m-3m. The angle of the rear antenna relative to the vertical plane is less than 45°. This allows the addition of a rear antenna to the existing channel with only a front toll antenna, while avoiding detection blind spots and interference between the rear antenna signal and the front antenna signal.

[0013] As a further optimization of this utility model, the distance from the rear antenna to the rear of the barrier mechanism is 2m, and the angle of the rear antenna relative to the vertical plane is 40°.

[0014] As a further optimization of this utility model, the toll island is provided with an L-shaped support rod, which includes a horizontal bar for mounting a rear antenna, and the angle of the rear antenna relative to the vertical plane can be adjusted.

[0015] In existing equipment, the rear antenna can be mounted on an adjustable mounting bracket, which is then mounted on an L-shaped support rod. However, the adjustable mounting bracket is relatively expensive and cannot adjust the angle of the rear antenna under significant external force. As a further optimization of this invention, a rotating cylinder is threaded onto the outside of the crossbar. The rotating cylinder has a through groove along its axial direction on its outer side, and a mounting plate is slidably mounted in the through groove. The rear antenna is mounted on the mounting plate, and the angle of the rear antenna relative to the vertical plane is adjusted by rotating the rotating cylinder.

[0016] Preferably, the crossbar is provided with a limiting plate, and the mounting plate has a portion extending out of the rotating cylinder and able to abut against the limiting plate. After the angle of the rear antenna relative to the vertical plane is adjusted, the mounting plate can be slid to make the portion extending out of the rotating cylinder abut against the limiting plate to adjust the position of the rear antenna. The mounting plate and the limiting plate can be welded and fixed together.

[0017] As a further optimization of this utility model, the L-shaped support rod has a receiving hole for accommodating the wire connected to the rear antenna. A through hole communicating with the receiving hole is provided on the side of the crossbar. After the rear antenna is installed, the wire connected to the rear antenna can pass through the through hole into the receiving hole, thereby preventing the wire from becoming tangled.

[0018] It should be noted that those skilled in the art should know that after installation, the gap between the through hole and the wire should be sealed with foam adhesive or other soft sealing materials.

[0019] As a further optimization of this utility model, the front antenna is located in front of the barrier gate, and the distance between the front antenna and the barrier gate is 8m-12m.

[0020] In this invention, the proposed ETC bus lane layout achieves either a dual-antenna toll collection mode or a single-antenna mode with a front antenna by setting a rear-mounted trigger coil, allowing for flexible switching of the toll collection mode based on traffic flow. Furthermore, since the power of the rear antenna is less than that of the front antenna, and the rear antenna is triggered by the rear-mounted trigger coil, mutual interference between the two antennas is avoided. The mutual interference between the two antennas is also avoided by adjusting the angle of the rear antenna relative to the vertical plane. In addition, the cost is reduced by setting a rotating cylinder.

[0021] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] like Figure 1 The diagram shows a lane layout for an ETC-dedicated passenger vehicle lane, used for toll collection in lane 1. Lane 1 has toll islands 2 on both sides. A front antenna 3 and a rear antenna 4 are mounted above lane 1, connected to a central control system. A barrier gate 5 is mounted on the toll island 2. The opening and closing of the barrier gate 5 is used to block or allow passage in lane 1. The barrier gate 5 communicates with the central control system. Similar to existing technologies, if the central control system determines that the vehicle has paid, it controls the barrier gate 5 to raise the barrier. The power of the rear antenna 4 is lower than that of the front antenna 3. The power of the front antenna 3 is the same as that of a single antenna used for toll collection on existing highways. The lower power of the rear antenna 4 ensures the efficiency of the front antenna 3 while avoiding signal interference between the two antennas.

[0027] The channel 1 is equipped with a second trigger coil 6 connected to the central control system. The second trigger coil 6 is close to the barrier gate 5 relative to the front antenna. It also includes a rear trigger coil 7, which is set on the channel 1 and is close to the barrier gate 5 relative to the second trigger coil 6. That is, the rear trigger coil 7 is set behind the second trigger coil 6.

[0028] The rear trigger coil 7 is connected to the central control system. The rear trigger coil 7 is used to detect whether a vehicle has passed by. If a vehicle passes the second trigger coil 6 and the central control system has not completed the toll collection, the central control system controls the rear trigger coil 7 to open. If the rear trigger coil 7 detects that a vehicle has passed by, it transmits the information to the central control system, and the central control system controls the rear antenna 4 to open for the second toll collection.

[0029] When there are many vehicles in lane 1, the front antenna 3 and the rear antenna 4 work together to achieve dual antenna participation in ETC toll collection and improve toll collection efficiency; when the traffic flow is low, toll collection can be carried out by the front antenna 3 alone (specifically, this can be achieved by de-energizing the rear trigger coil 7 or the rear antenna 4). When dual antennas participate in ETC toll collection, like the existing central control system, it has built-in existing toll collection software. During vehicle travel, the front antenna is in a normally open state. The central control system controls the front antenna 3 to perform the first toll collection. If the vehicle passes the second trigger coil 6 without completing the toll collection, the central control system controls the rear trigger coil 7 to open. The rear trigger coil 7 detects the vehicle passing by, and at this time, the central control system controls the rear antenna 4 to operate. During the operation of the rear antenna 4 or the front antenna 3, the rear antenna 4 or the front antenna 3 reads the OBU (On-Board Unit) information on the vehicle. After reading, the central control system controls the barrier gate 5 to raise the barrier to allow passage. When there are few vehicles, the rear trigger coil 7 can be turned off, and only the front antenna 3 participates in ETC toll collection. If the front antenna 3 fails to read the information and does not raise the barrier, the driver can complete the payment by reversing the vehicle or through the manual lane 1. Staff can adjust according to the actual situation.

[0030] The power of the rear antenna 4 is less than that of the front antenna 3. At the same time, the rear antenna 4 is triggered to turn on by the rear trigger coil 7, which can avoid interference from the rear antenna 4 when the front antenna 3 is working. Furthermore, the rear trigger coil 7 and the second trigger coil 6 can detect whether there is a queuing abnormality. If the rear trigger coil 7 and the second trigger coil 6 continuously detect vehicles, then there is a queuing abnormality.

[0031] Preferably, the channel 1 is further provided with a first trigger coil 8 connected to the central control system, and the front antenna 3 is located between the first trigger coil 8 and the second trigger coil 6. The first trigger coil 8 and the second trigger coil 6 are used to detect the vehicle's driving direction.

[0032] Preferably, the rear antenna 4 is located behind the barrier gate 5, and the distance between the rear antenna 4 and the barrier gate 5 is 1m-3m. The angle of the rear antenna 4 relative to the vertical plane is less than 45°. This allows the addition of the rear antenna 4 to the existing channel 1 which only has a front toll antenna, and avoids detection blind spots and interference between the signals of the rear antenna 4 and the front antenna 3. In this embodiment, the distance between the rear antenna 4 and the rear of the barrier gate 5 is 2m, and the angle of the rear antenna 4 relative to the vertical plane is 40°. Tests have shown that when the distance between the rear antenna 4 and the rear of the barrier gate 5 is 2m, the information reading effect is better at this angle.

[0033] like Figure 2As shown, in some preferred embodiments, the toll island 2 is provided with an L-shaped support rod 9. The L-shaped support rod 9 includes a horizontal rod 90 for mounting the rear antenna 4 and a vertical rod 91 fixed on the toll island 2. As with the prior art, the vertical rod 91 and the horizontal rod 90 can be connected by welding. Since there is an error in the distance from the support frame to the rear of the barrier gate 5, as a better solution in this embodiment, the angle of the rear antenna 4 relative to the vertical plane can be finely adjusted during the installation process. When the distance from the rear antenna 4 to the rear of the barrier gate 5 is greater than 2m, the angle of the rear antenna 4 relative to the vertical plane is adjusted to be greater than 40°. When the distance from the rear antenna 4 to the rear of the barrier gate 5 is less than 2m, the angle of the rear antenna 4 relative to the vertical plane is adjusted to be less than 40°.

[0034] Those skilled in the art can use existing mounting brackets that allow adjustment of the angle of the rear antenna 4 relative to the vertical plane for installation. To save costs, the present invention can also adopt the following solution:

[0035] A rotating cylinder 10 is threaded onto the outside of the crossbar 90. It should be noted that, to increase stability, the crossbar 90 has a solid part and a hollow part, which can be connected by welding. The inner hole of the hollow part is for accommodating wires. The solid part has an external thread and the rotating cylinder 10 is installed thereon. The hollow part is closer to and connected to the vertical bar 11 than the solid part. The rotating cylinder 10 is made of aluminum alloy or other metal material and is rust-proofed. A T-shaped through slot 100 is formed along the axis of the rotating cylinder 10. A mounting plate 11 is slidably installed in the T-shaped channel 1. The rear antenna 4 is mounted on the mounting plate 11. The bottom of the device is equipped with a T-shaped slider 110, which is slidably connected to the T-shaped through slot 100 to prevent the mounting plate 11 from falling out of the through slot 100 of the rotating cylinder 10 under gravity. Rotating the rotating cylinder 10 adjusts the angle of the rear antenna 4 relative to the vertical plane. Sliding the mounting plate 11 adjusts the position of the rear antenna 4 in the width direction of the channel 1, preventing the rear antenna 4 from being misaligned in the width direction of the channel 1 due to rotating the rotating cylinder 10. After the angle of the rotating cylinder 10 is adjusted, sliding the mounting plate 11 positions the rear antenna 4 in the width direction of the channel 1. The T-shaped slider 110 can be fixed in the T-shaped through slot 100 by welding. Compared to the existing method of mounting the rear antenna 4 using a saddle clip, this method makes it easier to adjust the angle of the rear antenna 4 and is more cost-effective than purchasing a mounting bracket for installation.

[0036] Preferably, a limiting plate 12 is provided on the crossbar 90. The limiting plate 12 can be integrally formed with the crossbar 90 or fixed to the crossbar 90 by welding. The mounting plate 11 has a portion extending out of the rotating cylinder 10 and abutting against the limiting plate 12. Specifically, the T-shaped slider 110 of the mounting plate 11 extends out of the mounting plate 11. When one end of the T-shaped slider 110 contacts the limiting plate 12, the rear antenna 4 on the mounting plate 11 is in the middle of the channel 1. Specifically, after the angle of the rear antenna 4 relative to the vertical plane is adjusted, the sliding mounting plate 11 makes the T-shaped slider 110 contact the limiting plate 12, and the T-shaped slider 110 is welded and fixed to the limiting plate 12 by welding.

[0037] Preferably, as in the prior art, the L-shaped support rod 9 has a receiving hole for accommodating the wire connected to the rear antenna 4, and the side of the crossbar 90 has a through hole 900 communicating with the receiving hole. After the rear antenna 4 is installed, the wire connected to the rear antenna 4 can pass through the through hole 900 into the receiving hole, thereby avoiding the wire from becoming tangled.

[0038] It should be noted that those skilled in the art should know that after installation, the gap between the through hole 900 and the wire should be sealed with foam adhesive or other soft sealing materials.

[0039] Preferably, the front antenna 3 is located in front of the barrier gate 5, and the distance between the front antenna 3 and the barrier gate 5 is 8m-12m.

[0040] It should be understood that the terms "lateral", "up", "front", "rear", "vertical", "axial", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0041] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0042] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Moreover, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
