Description

Technical Field

[0001] The utility model relates to the technical field of intelligent transportation, and in particular to an anti-slip ETC system. Background Art

[0002] ETC (Electronic Toll Collection) is an electronic toll collection system. The ETC dedicated lane is for vehicles equipped with ETC on-board equipment. ETC adopts electronic toll collection, through dedicated short-range communication between the on-board electronic tag installed on the vehicle windshield and the microwave antenna on the ETC lane at the toll station, and uses computer networking technology to conduct back-end settlement processing with the bank, so that vehicles can pay highway or bridge fees without stopping at highway or bridge toll stations. With the development of highways, ETC has also been popularized to the majority of car owners, bringing great convenience to everyone when passing through. However, there are also some such car owners who like to take advantage of other car owners' vehicles equipped with ETC on-board equipment to evade highway tolls, which seriously affects the safety of highway traffic.

[0003] At present, some vehicles are using the ETC lane in the following situations: deliberately driving slowly in the ETC lane, waiting for the vehicle with ETC on-board equipment behind to approach and be recognized by the ETC lane, and then accelerating through when the barrier is raised; waiting for an opportunity in the lane beside, and when the vehicle with ETC on-board equipment is recognized by the ETC lane, they quickly turn into the ETC lane and drive away when the barrier is raised; a method similar to conjoined twins is to stick tightly behind the vehicle with ETC on-board equipment in front, and quickly follow it after the barrier is raised.

[0007] After the target vehicle transacts with the ETC sensing antenna, when the front vehicle existence coil detects the existence of a vehicle at the current position, or when there is a vehicle behind the target vehicle and the rear vehicle cannot be recognized by the ETC license plate recognition machine, or when the detection camera recognizes that there is a vehicle at the dividing line between two adjacent ETC lanes, the barrier machine will not open.

[0008] In the embodiment of the present application, after the target vehicle has transacted with the ETC sensing antenna, when the coil of the vehicle in front detects that there is a vehicle at the current position, the barrier machine will not be turned on, thereby preventing the vehicle in front from rubbing against the vehicle behind which is equipped with the ETC vehicle-mounted device.

[0032] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] The embodiment of the present application provides an anti-slip ETC system, which can solve the problem that some vehicles slip into the ETC lane in the technology.

[0034] like Figure 1 As shown, the present application provides an embodiment of an anti-scratch ETC system, which includes: an ETC lane 8, a roadside unit coil 2, a license plate recognition coil 3, an ETC sensing antenna 5, and a barrier machine 6. The roadside unit coil 2, the license plate recognition coil 3, the ETC sensing antenna 5, and the barrier machine 6 are sequentially arranged in the ETC lane 8 along the entrance of the ETC lane 8, and the barrier machine 6 is located on one side of the ETC lane 8. The system also includes: a detection camera 14, a front vehicle existence coil 4, and two infrared curtains 9. The detection camera 14 is arranged in front of the entrance of the ETC lane 8; the front vehicle existence coil 4 is located in the ETC lane 8 and between the license plate recognition coil 3 and the ETC sensing antenna 5, and is used to detect whether there is a vehicle at the location; the two infrared curtains 9 are arranged on both sides of the ETC lane 8 and behind the roadside unit coil 2; the detection camera 14, the front vehicle existence coil 4, and the infrared curtains 9 are all connected to the lane control machine.

[0035] After the target vehicle has transacted with the ETC sensing antenna 5, when the front vehicle presence coil 4 detects the presence of a vehicle at the current position, the barrier machine 6 does not open, thereby preventing the front vehicle from rubbing against the vehicle behind which is equipped with the ETC vehicle-mounted device. When there is a vehicle behind the target vehicle, and the infrared curtain 9 detects that the rear vehicle cannot be recognized by the ETC license plate recognition machine 10, the barrier machine 6 does not open, thereby effectively controlling the following distance of the vehicle, thereby preventing the rear vehicle from rubbing against the vehicle in front which is equipped with the ETC vehicle-mounted device. When the detection camera 14 recognizes that there is a vehicle at the dividing line between two adjacent ETC lanes 8, the barrier machine 6 does not open, thereby effectively preventing the vehicles in the adjacent lanes from taking the opportunity to invade the ETC lane 8 and evade paying the highway toll.

[0036] Furthermore, the license plate recognized by the license plate recognition machine 10 includes the front license plate and / or the rear license plate. Since the license plate recognition machine 10 can at least recognize one of the front license plate or the rear license plate, the recognition efficiency of the license plate recognition machine 10 is relatively high.

[0037] like Figure 1As shown, in some embodiments, the system further includes a ground sensor coil 1, which is located in the ETC lane 8 and in front of the roadside unit coil 2, and the ground sensor coil 1 is connected to the lane controller. By setting the ground sensor coil 1, it can be used to identify whether the vehicle enters the ETC lane 8.

[0038] like Figure 1 As shown, in some embodiments, the system includes a bar-dropping coil 7, which is located in the ETC lane 8 and behind the barrier 6, and is connected to the barrier 6. When the vehicle is located at the bar-dropping coil 7, the vehicle has left the barrier 6, and the barrier of the barrier 6 is closed to prevent the rear vehicle from following the front vehicle through the barrier 6.

[0039] like Figure 1 As shown, in some embodiments, the system further includes a laser vehicle detector 11, and the number of the laser vehicle detectors 11 is two. Both laser vehicle detectors 11 are located on one side of the ETC lane 8, one of the laser vehicle detectors 11 is located between the front vehicle existence coil 4 and the ETC sensing antenna 5, and the other laser vehicle detector 11 is located between the ETC sensing antenna 5 and the barrier machine 6. The laser vehicle detector 11 is connected to the lane control machine and is used to separate the vehicles before and after the ETC sensing antenna 5.

[0040] like Figure 1 As shown, in some embodiments, the system further includes a lane information display screen 12, which is located on one side of the ETC lane 8 and behind the barrier machine 6, and the lane information display screen 12 is connected to the lane control machine. When the target vehicle trades with the ETC sensing antenna 5, the lane information display screen 12 is used to display the vehicle's license plate number, passing time and fee information.

[0041] Furthermore, the lane information display screen 12 is provided with an alarm device (not shown), which is connected to the lane controller. When a special situation occurs, the alarm device starts an alarm response, for example, when the target vehicle trades with the ETC sensing antenna 5, the front vehicle presence coil 4 detects the presence of a vehicle at the current position, or when there is a rear vehicle behind the target vehicle and the infrared curtain 9 detects that the rear vehicle cannot be recognized by the ETC license plate recognition machine 10, or when the detection camera 14 recognizes that there is a vehicle at the dividing line of two adjacent ETC lanes 8, the alarm device starts an alarm response.

[0042] like Figure 1 As shown, in some embodiments, the system further includes a lane camera 13, which is located at one side of the exit of the ETC lane 8 and is connected to the lane controller. The lane camera 13 is used to photograph vehicles coming out of the ETC lane 8, and can record some vehicles that are not recognized by the ETC lane 8 or vehicles equipped with ETC on-board equipment for subsequent processing.

[0043] like Figure 1 As shown, in some embodiments, the system further includes fog lamps 15 for lighting, which are located on both sides of the entrance of the ETC lane 8 and are connected to the lane controller. When the visibility is poor, such as in foggy days and at night, the fog lamps 15 can be turned on to illuminate the vehicles entering the ETC lane 8, thereby avoiding traffic accidents.

[0044] like Figure 1 As shown, in some embodiments, the ETC sensing antenna 5 is provided with an LED indicator light 51 for indicating traffic signals, and the LED indicator light 51 is connected to the lane controller. By providing the LED indicator light 51, vehicles can enter and exit the ETC lane 8 in an orderly manner to avoid congestion or traffic accidents.

[0045] On the other hand, the present application provides a working principle of an anti-scratch ETC system. When the target vehicle enters the ETC lane 8, the ground sensor coil 1 recognizes that a vehicle has entered and notifies the roadside unit coil 2. The roadside unit coil 2 activates the ETC on-board device on the target vehicle. The ETC on-board device communicates with the ETC sensing antenna 5. After the communication is completed, the vehicle information is transmitted to the lane controller, and the lane controller controls the opening of the barrier machine 6. After the target vehicle and the ETC sensing antenna 5 are traded, when the front vehicle existence coil 4 detects that there is a vehicle at the current position, the barrier machine 6 does not open. When there is a vehicle behind the target vehicle, and the infrared curtain 9 detects that the rear vehicle cannot be recognized by the ETC license plate recognition machine 10, the barrier machine 6 does not open. When the detection camera 14 recognizes that there is a vehicle at the dividing line between two adjacent ETC lanes 8, the barrier machine 6 does not open.

[0046] In summary, the present application adds a front vehicle presence coil 4 to the original ETC lane 8. When the target vehicle exchanges with the ETC sensing antenna 5, the front vehicle presence coil 4 detects the presence of a vehicle at the current position, and the barrier machine 6 does not open, thereby avoiding the situation where the front vehicle rubs against the vehicle with ETC vehicle-mounted equipment behind. At the same time, an infrared curtain 9 is added to the original ETC lane 8. When there is a vehicle behind the target vehicle and the vehicle behind cannot be recognized by the ETC license plate recognition machine 10, the barrier machine 6 does not open, effectively controlling the following distance of the vehicle and avoiding the situation where the vehicle behind rubs against the vehicle with ETC vehicle-mounted equipment in front. A detection camera 14 is added to the original ETC lane 8. When the target vehicle exchanges with the ETC sensing antenna 5, the detection camera 14 recognizes that there is a vehicle at the dividing line of two adjacent ETC lanes 8, and the barrier machine 6 does not open, effectively avoiding the problem of the adjacent lane waiting for an opportunity to invade the ETC lane 8 and evade paying the highway toll.
