Description

Technical Field

[0001] The present invention relates to the technical field of vehicle-mounted ETC toll collection technology, and in particular to a single-chip ETC vehicle-mounted device toll collection system, method, device and storage medium. Background Art

[0002] Single-chip ETC products have been widely used. Compared with the traditional dual-chip, the single-chip has advantages in structure and reliability. The single-chip ETC integrates the card into the ESAM chip, reduces the non-contact circuit card reader that consumes a lot of energy, and transforms the ETC protocol, so that it can process DSRC and non-contact dual-channel data in the 5.8Ghz frequency band, which is advanced to a certain extent. However, in order to cooperate with the progress of automobile optional work, the design time of the single-chip ETC product was short, and the rationality of the issuance and passage scenarios was not fully demonstrated, which led to some problems in the subsequent use process. Some of them were strongly reflected by customers, which affected the promotion of the optional ETC work to a certain extent. The main problems in use are as follows:

[0003] First, there is the problem of truck card swiping. Because the truck industry involves business operations, especially those with green pass business, the ETC exit must first remove the card, and then pass without paying after successful verification. Otherwise, the ETC deduction is successful and the refund process must be followed. At present, ordinary single-chip cannot do this; secondly, the ETC equipment senses a fault at the exit toll station, and it is impossible to swipe the card to pay when switching to the manual lane. When charging through online, the card number, license plate number and other information must be provided, which brings a poor experience to ETC users. Third, regardless of single-chip or dual-chip, due to the mixed design of communication modules and data modules, it is difficult to locate the problem. Generally, a set of damage will be replaced, resulting in cost waste and customer losses, especially cancellation, blacklisting, etc., because the equipment cannot be used due to the system. At this stage, the operation center can still let the manufacturer cover the bottom, but in the future, it may charge for maintenance, and the waiting period will also cause trouble to customers; finally, in the scene of car lending and renting, the closing and activation of ETC is now mainly through APP and Bluetooth, which is cumbersome and has room for further optimization.

[0004] Therefore, there is an urgent need for a single-chip ETC vehicle-mounted system for trucks used on highways, which can implement issuance and charging methods to solve the above problems. Summary of the invention

[0036] Example:

[0037] like Figure 1 As shown, this embodiment provides a monolithic ETC vehicle-mounted device charging system, including a base module and a transaction module, the base module includes a power supply unit, the power supply unit is electrically connected to a road test communication unit and a Bluetooth unit, the road test communication unit is data connected to the Bluetooth unit, the Bluetooth unit is data connected to a mobile phone user terminal, the transaction module includes an ESAM chip, and the ESAM chip includes:

[0038] The vehicle information storage module is used to: store vehicle information;

[0039] The device information storage module is used to store ETC device information;

[0040] The transaction file information storage module is used to store the transaction file information of the ETC device.

[0041] The base module also includes an ETC information cache area, which is data-connected to the transaction module. A hidden card box is disposed on the outside of the base module, and an LED light tube is disposed through the side wall of the hidden card box, and the LED light tube is electrically connected to the power supply unit.

[0042] In this embodiment, the base, as the core component of ETC, needs to be fixedly installed on the car. It is composed of power supply (battery replacement), roadside communication, mobile phone Bluetooth, etc., and is equipped with an ETC information cache area, a hidden card box, and an LED light tube. The transaction module is independently disassembled and contains the entire ESAM chip. The module writes vehicle information, equipment system information and dual-chip ETC card transaction file information, and has a transaction coil. The appearance can be thickened to CPC style or ordinary style.

[0043] like Figure 2 As shown, this embodiment also provides a charging method applied to the above-mentioned single-chip ETC vehicle-mounted device charging system, comprising the following steps:

[0044] S1: The base module collects data information from the road test equipment and sends it to the transaction module. The base module cannot be used alone and must be used with a transaction module. It is defined as an auxiliary transaction channel and is responsible for protocol interaction and data transmission with the roadside equipment and transaction module. However, it has no processing capability for encrypted data and does not store data itself.

[0045] S2: The transaction module processes the collected information. The function of the transaction module is to clear and settle, process transaction logic, and participate in customer special situation processing. In order to keep the single-chip transaction speed from decreasing, the ETC card and the card holder can communicate through SPI data;

[0046] S3: The base module sends the processed data to the mobile phone user terminal.

[0047] The base module is treated to prevent disassembly and will become invalid after disassembly. The base can achieve CAN anti-disassembly when communicating with a vehicle that has the conditions for vehicle communication. A base that does not have the conditions should have the car VIN information written into it. This information is used to verify the matching of the card. Later, depending on the department's policy, the verification can be removed by remote upgrading. Due to the current online billing writing requirements, the base module has a cache area for data exchange to prevent the transaction module from popping up during operation.

[0048] like Figure 3 As shown, the transaction module follows the following logic:

[0049] S4: RSU searches for OBU until it finds it;

[0050] S5: RSU sends OBU number information (B2 frame) to PC, and PC responds to C1 command;

[0051] S6: RSU reads OBU attributes and sends OBU attributes (B3 frame) to PC, and PC responds to C1 command;

[0052] S7: RSU reads the IC card information and sends the IC card information (B4 frame) to PC, and PC sends C6 command to RSU;

[0053] S8: RSU writes the entry file to OBU. If it fails, it goes to step S4.

[0054] In addition, the single-chip ETC vehicle-mounted device charging system involved in this embodiment also has the following functions:

[0055] (1) Cancellation

[0056] For individuals and vehicles, only the card can be cancelled, and the obu can be unbound;

[0057] (2) Car transfer

[0058] When the car is transferred, the obu data can be cleared with one click. The card is transferred according to the individual. If obu wants to continue to use it, it can reinstall the synchronized card data and continue to use it;

[0059] (3) Remote upgrade

[0060] The base program can be upgraded to support other processing logic in the future.

[0061] The contents of the above method embodiments are all applicable to the present system embodiments. The functions specifically implemented by the present system embodiments are the same as those of the above method embodiments, and the beneficial effects achieved are also the same as those achieved by the above method embodiments.

[0062] This embodiment also provides a device, including:

[0063] at least one processor;

[0064] At least one memory for storing at least one program;

[0065] When the at least one program is executed by at least one processor, the at least one processor implements a charging method applied to the above-mentioned single-chip ETC vehicle-mounted device charging system.

[0066] This embodiment also provides a storage medium, which stores a program, and the program is executed by a processor to complete a charging method applied to the above-mentioned single-chip ETC vehicle-mounted device charging system.

[0067] 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. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
