In order to bind with the target OBU, the vehicle-mounted terminal device sends a broadcast message to the broadcasting range of the vehicle-mounted terminal device to acquire identification information (for example, OBU identification) of the OBU in the broadcasting range. The broadcast message may be: a standard broadcast frame BST.

After receiving the broadcast message, the target OBU located in the broadcast range may carry identification information (target identification information) of itself in a first response message, and send the first response message to the vehicle-mounted terminal device, where the first response message may be: the frame VST is repeated.

After receiving the first response message, the vehicle-mounted terminal device may extract the target identification information carried in the first response message, and bind the vehicle-mounted terminal device and the target OBU according to the target identification information, where the binding mode may be: and writing the target identification information into a specific position of the vehicle-mounted terminal equipment so as to limit the binding relationship between the vehicle-mounted terminal equipment and the target OBU.

For example, the manner of binding the ETC vehicle-mounted terminal and the vehicle-mounted electronic tag may be as shown in fig. 5, and the binding process may include the following steps:

step S502, the ETC vehicle-mounted terminal sends a standard broadcast frame BST to the vehicle-mounted electronic tag;

After receiving the plurality of identification information, the vehicle-mounted terminal device displays the plurality of identification information on a screen of the vehicle-mounted terminal device (for example, displays the plurality of identification information in a list form), and prompts a user to select an OBU to be bound.

And the user selects target identification information (target OBU) for binding according to the prompt of the vehicle-mounted terminal equipment. The vehicle-mounted terminal equipment detects the selection operation of the target identification information in the plurality of identification information and generates a selection instruction, and the selection instruction is used for indicating that the target identification information is selected from the plurality of identification information and is bound; and responding to the selection instruction, and binding the vehicle-mounted terminal equipment and the target OBU by the vehicle-mounted terminal equipment according to the target identification information.

For example, there are a plurality of OBUs located in the broadcast range of the vehicle-mounted terminal device of the target vehicle, including OBU 1, OBU2 and OBU 3, and the corresponding identification information is OBU identifier 1, OBU identifier 2 and OBU identifier 3, respectively, where OBU2 is the target OBU. After receiving the three OBU identifiers, the vehicle-mounted terminal device displays the three OBU identifiers on a screen (which may be a touch screen). And the user selects the OBU identifier 2 as the OBU identifier to be bound. And responding to the selection operation of the user, and binding the vehicle-mounted terminal equipment with the OBU identifier 2 by the vehicle-mounted terminal equipment.

Through this embodiment, through a plurality of identification information that show on vehicle terminal's screen and receive to binding according to selecting the instruction and carrying out vehicle terminal and target OBU, can guarantee the accuracy that vehicle terminal binds with the OBU.

After the vehicle-mounted terminal device is bound with the target OBU, an operation instruction can be sent to the target OBU to realize various controls on the target OBU, which may include but is not limited to at least one of the following: user autonomous activation, OBU awakening, OBU dormancy, information inquiry and the like.

For example, the manner in which the vehicle-mounted terminal device controls the vehicle-mounted electronic tag may be as shown in fig. 6, and the flow may include the following steps:

in step S602, the ETC in-vehicle terminal transmits an instruction frame for operating the OBU to the OBU.

And step S606, the ETC vehicle-mounted terminal receives the response frame, extracts information and displays the information to the user.

After receiving the response frame transfer.

Because the vehicle-mounted electronic tag is generally designed with low power consumption and is in a sleep mode (low power consumption mode) when not in work, before the vehicle-mounted terminal device sends a control instruction to the target OBU, the target OBU can be wakened up through the wake-up instruction, and then the vehicle-mounted terminal device enters the wake-up mode (wake-up state).

As an optional implementation manner, the vehicle-mounted terminal device sends a wake-up instruction to the target OBU, wherein the wake-up instruction is used for instructing to wake up the target OBU; and the vehicle-mounted terminal equipment receives a third response message sent by the target OBU responding to the awakening instruction, wherein the third response message is used for indicating that the target OBU is awakened successfully.

The vehicle-mounted terminal device may wake up the target OBU by sending a control instruction, such as a wake-up instruction, to the target OBU, where the wake-up process may be as shown in fig. 5, and is not described herein.

Through this embodiment, through sending awakening instruction to target OBU and carrying out awakening of target OBU, can guarantee that target OBU is in normal operating condition, improve the success rate with target OBU interactive.

The OBU equipment has relatively weak storage and data processing functions, cannot realize the viewing of consumption information at any time, cannot realize the summary analysis of historical data, and cannot realize a large data analysis and display function which provides convenience for users; on the other hand, the operation of the user on the OBU is relatively less, typically, the card information is obtained by plugging and unplugging the card, and the MAC, SN, historical transaction records and the like of the OBU cannot be inquired or need a special method, which undoubtedly increases the difficulty of using the OBU for the user.

In this embodiment, after the target OBU is awakened, the vehicle-mounted terminal device may send other control instructions, such as an account binding instruction and an inquiry instruction, to the target OBU, so as to control the target OBU.

As an optional implementation manner, the vehicle-mounted terminal device sends an account binding instruction to the target OBU, wherein the account binding instruction is used for indicating that the target OBU is bound with the target account, and the target account is a charging account of the target OBU; and the vehicle-mounted terminal equipment receives a second response message sent by the target OBU response account binding instruction, wherein the second response message is used for indicating that the target OBU is successfully bound with the target account.

After the target OBU is installed, the target OBU needs to be bound with a specific deduction account number to realize ETC charging. The binding mode can be as follows: card information is acquired through plugging and unplugging the card, account binding is carried out on specific equipment of a business hall, and account binding can also be carried out in a mode of writing an account into a vehicle-mounted terminal device.

After acquiring a target account (for example, a user manually inputs the target account, reads the account through a card reading function, and identifies the target account in a shot picture of a card through a picture identification function), the vehicle-mounted terminal device sends an account binding instruction to the target OBU to indicate that the target OBU is bound with the target account. And after receiving the account binding instruction, the target OBU extracts and stores the carried target account as a deduction account.

After the binding is successful, the target OBU can send a second response message to the vehicle-mounted terminal device to indicate that the binding of the target OBU and the target account is successful.

Through this embodiment, the mode of carrying the deduction account number to the target OBU through vehicle-mounted terminal equipment realizes the binding of target OBU and deduction account number, can improve the convenience that the deduction account number was bound.

Besides the account binding instruction, the vehicle-mounted terminal device may also send an information query instruction, an account modification instruction, and the like to the target OBU to query information stored in the target OBU and modify the charging account bound by the target OBU, and the interaction flow may be as shown in fig. 5, which is not described herein.
