Description

Technical Field

[0001] The present invention relates to the technical field of ETC equipment identification, and in particular to a method and system for improving the identification rate of ETC equipment to be deducted at a parking lot exit. Background Art

[0002] The electronic toll collection system is an automated toll collection system based on wireless communication technology, which is widely used in highways, bridges, tunnels and other places. In recent years, with the development of intelligent transportation, the ETC system has also been applied to parking lot management, which can avoid vehicle congestion caused by waiting in line, improve traffic capacity, relieve traffic pressure, reduce management costs, save energy and protect the environment. ETC has been expanded from highway application scenarios to parking lots and gas stations, realizing fast entry and exit and add and go, greatly reducing transaction time and improving overall efficiency.

[0003] Currently, many parking lots support ETC deductions. However, in the existing ETC parking lot deduction system, when there are many vehicles queuing at the parking lot exit or there are multiple vehicles equipped with ETC devices parked near the exit, the wake-up signal sent by the antenna may wake up multiple ETC devices at the same time, causing the ETC device with the fastest response to the antenna to send the wake-up signal multiple times. Each time, the more sensitive ETC device is awakened the fastest, and the correct ETC device to be deducted cannot be found, resulting in ETC deduction failure. Other payment methods must be used, payment time is longer, and user experience is poor.

[0004] Therefore, there is an urgent need for a method and system to improve the recognition rate of ETC devices to be deducted at the parking lot exit to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a method and system for improving the recognition rate of ETC devices to be deducted at the parking lot exit, which can greatly improve the ability of the ETC device installed in the target vehicle to correctly wake up and complete the deduction process, thereby improving the traffic efficiency and user experience of the parking lot exit.

[0006] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0007] On the one hand, a method for improving the recognition rate of ETC devices to be deducted at a parking lot exit is provided, comprising the following steps:

[0008] S1: Collect information about vehicles entering the parking lot exit;

[0009] S2: Send the collected vehicle information to the ETC fee deduction software, which will analyze and process it;

[0010] S3: Send the analysis and processing results of the ETC fee deduction software to the antenna fee deduction software to determine the deduction form;

[0011] S4: Execute vehicle fee deduction behavior.

[0012] Preferably, in step S1, the vehicle information includes: vehicle license plate number, vehicle color, vehicle entry time, vehicle exit time and deduction amount.

[0013] Preferably, the ETC deduction software performs analysis and processing in step S2, specifically: the ETC deduction software determines whether the deduction notification and deduction information are received based on the vehicle information. If the deduction notification and deduction information are received, the next step is executed; if the deduction notification and deduction information are not received, the ETC deduction software does not perform any operation.

[0014] Preferably, step S3 comprises:

[0015] S31: The ETC deduction software receives the deduction notification and deduction information, sends a wake-up device signal to the antenna deduction software, and the antenna sends a BST signal. The BST timeout is set to N milliseconds. If no VST is received after N milliseconds, the BST signal will be sent again. If a VST signal is received, the BST signal will be stopped, and judgment will be made based on the received VST.

[0016] S32: The antenna fee deduction software will set a timeout of N seconds to wake up the ETC device. If the corresponding ETC device is not woken up within N seconds, it will return that the ETC fee deduction failed and the corresponding ETC device was not found.

[0017] Preferably, the determination based on the received VST is specifically: determining the card signature information, including:

[0018] If there is no card in the OBU, read the OBU vehicle information again, compare the OBU license plate number with the license plate number of the vehicle to be deducted, and release the OBU link if the license plate numbers are consistent, return the failure of deduction without ETC card, and change other deduction methods;

[0019] If there is no card in the OBU, the OBU vehicle information is read again, and the OBU license plate number is compared with the license plate number of the to-be-deducted vehicle. If the license plate numbers are inconsistent, a link is established with the OBU, and the signal for reading the vehicle is continued to be sent. The link is maintained for N seconds, and the BST signal is continuously sent within N seconds. If the device does not respond to the wake-up signal sent within N seconds, it continues to send the ETC device wake-up signal;

[0020] If there is an ETC card in the OBU, the license plate number information in the returned ETC card is compared to determine whether the license plate number is consistent with the license plate number to be deducted. If they are consistent, the subsequent deduction operation process is carried out with the ETC;

[0021] If there is an ETC card in the OBU, and it is determined that the license plate number in the card is inconsistent with the license plate number to be deducted, a link is established with the OBU, and the signal to read the vehicle continues to be sent. The link is maintained, and no response is made to the subsequent wake-up device, and the ETC device wake-up signal continues to be sent.

[0022] On the other hand, a system is provided based on the method for improving the recognition rate of ETC devices to be deducted at the parking lot exit according to claim 5, comprising:

[0023] The data collection module is used to collect information about vehicles entering the parking lot exit;

[0024] The data processing module is used to: send the collected vehicle information to the ETC fee deduction software, and the ETC fee deduction software will analyze and process it; at the same time, send the analysis and processing results of the ETC fee deduction software to the antenna fee deduction software to determine the deduction form;

[0025] The data output module is used to: execute vehicle fee deduction actions.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] By improving the antenna wake-up mechanism and sending BST to wake up the device, the ETC device of VST is first returned to obtain the card signature information of the ETC device and compare the license plate number. If the comparison is consistent, the ETC fee deduction process is carried out. If the comparison is inconsistent, the vehicle information is sent to the ETC device to keep the OBU connected and not receive the BST signal sent again. The same operation is repeated N times, which greatly improves the target vehicle installed ETC device to be able to correctly wake up and complete the fee deduction process, thereby improving the traffic efficiency and user experience of the parking lot exit.

[0034] Example:

[0035] The existing parking lot ETC antenna fee deduction software is upgraded, and an OBU signal interference mechanism is added to improve the success rate of ETC fee deduction transactions. Parking lots that have installed antennas are the first choice for ETC fee deduction. If ETC fee deduction fails, users can choose to scan the code to pay.

[0036] like Figure 1 As shown, this embodiment provides a method for improving the recognition rate of ETC devices to be deducted at a parking lot exit, including the following steps:

[0037] S1: Collect information about vehicles entering the parking lot exit;

[0038] S2: Send the collected vehicle information to the ETC fee deduction software, which will analyze and process it;

[0039] S3: Send the analysis and processing results of the ETC fee deduction software to the antenna fee deduction software to determine the deduction form;

[0040] S4: Execute vehicle fee deduction behavior.

[0041] In this embodiment, a black vehicle B with a license plate number A is taken as an example for specific description:

[0042] When vehicle B enters the parking lot exit, the parking lot system can automatically identify the license plate number A and the license plate color (black) through license plate recognition, and transmit the entry time, exit time, license plate number A, license plate color (black) and amount to be deducted of vehicle B to the ETC deduction software; the ETC deduction software receives the deduction notification and deduction information, sends a wake-up device signal to the antenna, and the antenna sends a BST signal. The BST timeout is generally set to N milliseconds. If no VST is received after N milliseconds, the BST signal will be sent again. If a VST signal is received, the BST will be stopped and the judgment will be made based on the received VST.

[0043] The antenna fee deduction software will also set a timeout of N seconds to wake up the ETC device. If the corresponding ETC device is not woken up within the timeout, it will return that the ETC fee deduction failed and the corresponding ETC device was not found.

[0044] The antenna sends a BST signal, and the antenna receives the returned VST, and determines the card signature information based on the VST information:

[0045] If there is no card in the OBU, it is necessary to read the OBU vehicle information again and compare the OBU license plate number with the license plate number of the vehicle to be deducted. If the license plate numbers are consistent, the OBU link will be released, and the deduction failure will be returned without ETC card, and other deduction methods will be used;

[0046] If there is no card in the OBU, it is necessary to read the OBU vehicle information again, compare the OBU license plate number with the license plate number to be deducted, and establish a link with the OBU if the license plate numbers are inconsistent, and continue to send signals to read the vehicle. The link is maintained for N seconds, and the BST signal is continuously sent within N seconds. If the device does not respond to the wake-up signal sent within N seconds, it continues to send the ETC device wake-up signal;

[0047] If there is an ETC card in the OBU, the license plate number information in the returned ETC card is compared to determine whether the license plate number is consistent with the license plate number to be deducted. If they are consistent, the subsequent deduction operation process is carried out with the ETC;

[0048] If there is an ETC card in the OBU, and it is determined that the license plate number in the card is inconsistent with the license plate number to be deducted, a link is established with the OBU, and the signal to read the vehicle continues to be sent. The link is maintained, and no response is made to the subsequent wake-up device, and the ETC device wake-up signal continues to be sent.

[0049] For multiple vehicles parked at the exit, when the antenna sends a wake-up signal, the ETC device with higher sensitivity that is not waiting for deduction will be awakened and maintained connected, and the ETC device wake-up signal will be sent multiple times. As long as the vehicle to be deducted has the ETC device installed normally, it can be awakened normally and the ETC deduction process can be completed, which greatly improves the success rate of ETC deduction.

[0050] The above is a specific description of the preferred implementation of the present invention, but the present invention is not limited to the described embodiments. Technicians in the field of transaction features between nodes can also make various equivalent deformations or substitutions without violating the spirit of the present invention. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
