[0051] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, further detailed description will be made to the embodiments of the present application with reference to the drawings. Herein, the illustrative embodiments of the present application and the description thereof are used to explain the present application, but not as a limitation to the present application. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other in any manner without conflict.

[0052] Figure 1 is a structural schematic diagram of the anti-scratching ETC system provided by an embodiment of the present application, as shown in Figure 1 which comprises a turn signal recognition system 5, a payment confirmation system 6, a lifting rod control system 7, and an ETC terminal 2 located in a vehicle; wherein:

[0053] The payment confirmation system 6 is configured to generate turn signal key data, and send the turn signal key data to the ETC terminal 2 and the turn signal recognition system 5, so that the vehicle corresponding to the ETC terminal 2 turns on the turn signal information according to the turn signal key data in the recognition area;

[0054] The turn signal recognition system 5 is configured to receive the turn signal information and the turn signal key data, and compare the turn signal information and the turn signal key data;

[0055] The lifting rod control system 7 is configured to determine whether to release the vehicle to drive away from the recognition area according to the comparison result.

[0056] As Figure 2 is shown, the whole process of the anti-scratching ETC system is briefly explained as follows:

[0057] I. First, an ETC terminal is installed in the ETC box of the front window of the vehicle, and the ETC terminal contains a voice broadcast system. When the ETC antenna signal is received in front of the ETC, the voice broadcast system can broadcast the following content to the driver:

[0058] “Turn on the left turn signal” or “turn on the right turn signal” or “turn on the double turn signal”, the three are the turn signal key data, and further a reminder can be sent, for example, “If you see the front vehicle scratching the ETC, please do not operate”.

[0059] II. The front rod 3 is raised, the vehicle drives to the recognition area, the driver turns on the turn signal according to the turn signal key data, and the light of the turn signal of the vehicle is recorded by four turn signal recording devices (i.e. turn signal recognition devices) for identifying whether the vehicle is allowed to pass. The front rod 3 can be lowered when the vehicle drives to the recognition area.

[0060] III. If the vehicle is allowed to pass, the rear rod 11 is raised, and the vehicle is released; if the vehicle is not allowed to pass, the rear rod 11 remains unchanged, and the vehicle cannot drive out of the identification area, and further staff can handle the vehicle that cannot drive out.

[0061] The turn signal key data generated by the payment confirmation system 6 can include the above-mentioned “turn on the left turn signal” or “turn on the right turn signal” or “turn on the double turn signal”.

[0062] The ETC terminal 2 receives the turn signal key data and broadcasts the turn signal key data through the voice broadcast system in the ETC terminal 2. The vehicle corresponding to the ETC terminal 2 drives to the identification area through the front rod 3, and turns on the turn signal according to the turn signal key data. The turn signal information can include the above-mentioned “turn on the left turn signal” or “turn on the right turn signal” or “turn on the double turn signal”. If the vehicle corresponding to the ETC terminal 2 turns on the turn signal correctly, the turn signal information is consistent with the turn signal key data; if the vehicle corresponding to the ETC terminal 2 turns on the turn signal incorrectly, the turn signal information is inconsistent with the turn signal key data.

[0063] It should be noted that if the vehicle that turns on the turn signal is different from the vehicle that receives the broadcast turn signal key data, it will also cause the turn signal to be inconsistent with the turn signal key data.

[0064] The turn signal identification system 5 receives the turn signal information and the turn signal key data, and compares the turn signal information and the turn signal key data. The purpose of comparison is to determine whether the turn signal is consistent with the turn signal key data.

[0065] The turn signal identification system 5 is also specifically used for:

[0066] If it is determined that the comparison result is consistent, an instruction to allow passing is sent to the payment confirmation system 6;

[0067] Correspondingly, the payment confirmation system 6 is also specifically used for:

[0068] According to the instruction to allow passing, an instruction to raise the rear rod 11 is sent to the rod lifting control system 7, so that the rod lifting control system 7 raises the rear rod 11 according to the instruction to raise the rear rod 11, to release the vehicle allowed to pass. This means that the vehicle is a paid vehicle, not an ETC vehicle.

[0069] The turn signal identification system 5 is also specifically used for:

[0070] If it is determined that the comparison result is inconsistent, an instruction not to allow passing is sent to the payment confirmation system 6;

[0071] Correspondingly, the payment confirmation system 6 is also specifically used for:

[0072] According to the instruction of not allowing to pass, the instruction of keeping the rear rod 11 in the down state is sent to the lifting rod control system 7, so that the lifting rod control system 7 continues to control the rear rod 11 to keep the down state, and does not release the vehicle that does not allow to pass, which indicates that the vehicle is a non-payment vehicle and is an ETC-squatted vehicle. Further, an artificial charging notification message can be sent, and the vehicle is charged by the relevant staff.

[0073] The anti-ETC-squatted system further comprises a turn signal recognition device 10.

[0074] The turn signal recognition device 10 is used to:

[0075] Obtain the turn signal information of the vehicle in the recognition area; for example, Figure 2 As shown, the turn signal information can be accurately obtained by four turn signal recognition devices 10.

[0076] The turn signal information is sent to the turn signal recognition system 5, so that the turn signal recognition system 5 can accurately obtain the turn signal information.

[0077] The turn signal recognition device 10 comprises a photosensitive device and an image device, and records multiple times according to different turn signal blinking frequencies. For the case of ETC-squatted, two cases can be included. One case is that the front vehicle rushes, and the other case is that the rear vehicle follows.

[0078] For the front vehicle rush, when the front rod 3 is lifted and the paid vehicle does not pass, other vehicles rush to pass. Due to the existence of the voice key, on the one hand, other vehicles do not know which turn signal to turn on, which can effectively deter other vehicles from entering, and on the other hand, if other vehicles enter the recognition area and cannot correctly turn on the turn signal, the rear rod 11 cannot be lifted, so that these vehicles cannot drive out of the recognition area.

[0079] For the rear vehicle follow, the most difficult to identify is the behavior of the rear vehicle sticking to follow. The present application also identifies according to the same identification method as the front vehicle rush, that is, when the paid vehicle passes through the front rod 3 and correctly turns on the turn signal, the rear vehicle also turns on the same turn signal, but due to the different blinking states of the turn signals of the front and rear vehicles, the rear rod 11 does not lift and release.

[0080] Due to the fact that the turn signal recognition device 10 can record multiple times according to different turn signal blinking frequencies, the blinking states of the turn signals of the front and rear vehicles are different, and when recording, the turn signals of the cross direction are blocked by the sticking vehicle. The turn signal of the paid vehicle can be blocked by the following vehicle, so that the following vehicle can be identified.

[0081] The anti-ETC-squatted system further comprises an ETC antenna 1.

[0082] The ETC antenna 1 is used for:

[0083] Monitoring the vehicle entering the ETC channel, and sending the vehicle information to the payment confirmation system 6; at this time, the vehicle can be a vehicle to be charged, and the vehicle information can be a license plate number, an owner identity information, etc.

[0084] Receiving the turn signal key data sent by the payment confirmation system 6 after confirming the vehicle information; the payment confirmation system 6 can charge the vehicle according to the vehicle information, that is, complete the confirmation of the vehicle information, and at this time, the vehicle is a vehicle that has paid the fee.

[0085] Sending the turn signal key data to the ETC terminal, that is, sending the turn signal key data to the ETC terminal 2 through the ETC antenna signal as shown in the figure. Figure 2

[0086] The payment confirmation system 6 is further used for:

[0087] When sending the turn signal key data to the ETC terminal 2 and the turn signal recognition system 5, the payment confirmation system 6 also sends an instruction to raise the front rod 3 to the lifting rod control system 7, so that the lifting rod control system raises the front rod 3 according to the instruction of the front rod 3, and makes the vehicle drive through the front rod 3 to the recognition area.

[0088] As shown in the figure, the data obtained by the ETC antenna 1 can be sent to the payment confirmation system 6 through the first network device 4. Figure 1 The data recognized by the turn signal recognition device 10 can be sent to the turn signal recognition system 5, etc. through the second network device 9.

[0120] The embodiment of the application further provides an anti-collision ETC method applied to the anti-collision ETC system, and the method comprises:

[0121] generating turn light key data;

[0122] When a vehicle activates its turn signal in the identification area based on the turn signal key data, the turn signal information and the turn signal key data are compared.

[0123] The decision on whether to allow the vehicle to leave the identified area is based on the comparison results.

[0124] For a detailed explanation, please refer to the above-described implementation example of the anti-cheating ETC system; it will not be repeated here.

[0125] The method for preventing ETC (Electronic Toll Collection) fraud provided in this invention generates turn signal key data; responds to a vehicle activating turn signal information in the identification area according to the turn signal key data, compares the turn signal information and the turn signal key data; and determines whether to allow the vehicle to leave the identification area based on the comparison result, which can effectively prevent vehicles that fraudulently use ETC from leaving the identification area.

[0126] Furthermore, determining whether to allow the vehicle to leave the identification area based on the comparison result includes:

[0127] If the comparison results are consistent, the vehicle is allowed to leave the identification area; please refer to the above-described embodiment of the anti-cheating ETC system for further details, which will not be repeated here.

[0128] If the comparison results are inconsistent, the vehicle will not be allowed to leave the identification area. Refer to the above-described embodiment of the anti-ETC fraud system for further details; it will not be repeated here.

[0129] The method for preventing ETC fraud provided in this embodiment of the invention can further effectively control whether a vehicle can leave the identification area.

[0130] like Figure 3 The methods for preventing ETC (Electronic Toll Collection) fraud are explained below:

[0131] ETC antenna 1 monitors vehicles entering the ETC lane and sends the vehicle information of the vehicles to be charged to the payment confirmation system;

[0132] If the payment confirmation system confirms that the vehicle to be charged has completed payment based on the vehicle information, it sends turn signal key data to the turn signal recognition system and ETC antenna 1, and sends a command to raise the front pole 3 to the pole lifting control system, so that the pole lifting control system can raise the front pole 3 according to the command.

[0133] ETC antenna 1 forwards turn signal key data to the ETC terminal of the toll-paid vehicle. The ETC terminal broadcasts the turn signal key data so that the toll-paid vehicle can drive through the front pole 3 to the identification area and activate the turn signal information according to the turn signal key data.

[0134] The turn signal recognition system controls the turn signal recognition device to obtain the turn signal information of the to-be-recognized vehicle in the recognition area, and sends the turn signal information to the turn signal recognition system; the front rod 3 can be lowered after the to-be-recognized vehicle passes through the front rod 3;

[0135] The turn signal recognition system compares the turn signal information and the turn signal key data, and if it is determined that the comparison result is consistent, an instruction of allowing to pass is sent to the payment confirmation system;

[0136] The payment confirmation system sends an instruction of lifting the rear rod 11 to the rod lifting control system according to the instruction of allowing to pass, so that the rod lifting control system lifts the rear rod 11 according to the instruction of lifting the rear rod 11, to release the vehicle allowed to pass;

[0137] If it is determined that the comparison result is inconsistent, an instruction of not allowing to pass is sent to the payment confirmation system;

[0138] The payment confirmation system sends an instruction of keeping the rear rod 11 in the lowered state to the rod lifting control system according to the instruction of not allowing to pass, so that the rod lifting control system continues to control the rear rod 11 to keep the lowered state, and does not release the vehicle not allowed to pass.

[0139] For the case that the driver of the rear vehicle sees the turn signal of the front vehicle (the payment vehicle) and opens the turn signal in the same way:

[0140] The method for preventing ETC also includes:

[0141] If it is determined that at least one turn signal recognition device records at least two different flashing frequency light information within a preset time period, the rear rod 11 is kept in the lowered state. The preset time period can be set autonomously according to actual conditions, and the value should not be too large, and should be less than the time interval of two payment vehicles normally passing through the recognition area, for example, 10 seconds. Since the flashing frequencies of the rear vehicle and the front vehicle are different, if the rear vehicle and the front vehicle both open the turn signal within 10 seconds, there are two light information records within 10 seconds, which means that there is a vehicle that wants to ride ETC among the two vehicles. By keeping the rear rod 11 in the lowered state, both vehicles cannot drive out of the recognition area, and wait for the relevant staff to handle.

[0142] The method for preventing ETC provided by the embodiment of the application can further effectively prevent the ETC from being ridden.

[0143] For the case that the shielding vehicle wants to pass together with the payment vehicle, specifically including the case that the shielding vehicle is before the payment vehicle, and the case that the shielding vehicle is after the payment vehicle,

[0144] The method for preventing ETC also includes:

[0145] acquire a vehicle image through each of the turn light recognition devices; the vehicle image comprises a vehicle light image;

[0146] If it is determined that at least one of the turn light recognition devices cannot acquire the vehicle light image of two vehicle lights of the same vehicle, and neither of the two vehicle lights of the same vehicle has a light, and the pixel distance between the two adjacent vehicles in the vehicle image is less than a preset pixel distance, the rear rod 11 is controlled to remain in the lowered state. Taking the first case as an example, the vehicle image acquired by the image device of the turn light recognition device is mainly to capture the vehicle light.

[0147] As shown in Figure 4 , the field of view of the No. 1 turn light recognition device is shown by the dashed lines in Figure 4 , wherein the vehicle light F is blocked, and the vehicle lights C and E that can be captured are not vehicle lights of the same vehicle.

[0148] The field of view of the No. 1 turn light recognition device can also include vehicle lights A and B, and the vehicle wants to pass through the toll vehicle first, but does not know the vehicle light key, so the vehicle lights A and B are not turned on, and therefore the vehicle lights A and B have no light.

[0149] The pixel distance between the two adjacent vehicles can reflect the real distance between the two adjacent vehicles, and if the real distance between the two adjacent vehicles is large, referring to Figure 4 , the case that the blocking vehicle is in front and the No. 1 turn light recognition device can capture the vehicle lights F and E will occur, and therefore the preset pixel distance can be reasonably determined according to the vehicle model and other information.

[0150] As shown in Figure 5 , for the second case, the first case can be referred to for explanation, which will not be repeated here.

[0151] The method for preventing ETC from being ridden provided by the embodiment of the application can further effectively prevent the case of preventing ETC from being ridden from occurring.
