Description

Technical Field

[0001] The present disclosure relates to the field of intelligent transportation technology, and in particular to an information processing method, device, storage medium and electronic device for ETC transactions. Background Art

[0002] Electronic Toll Collection (ETC) systems can be used for highway and urban road toll collection, parking lot toll collection and other applications. Existing ETC systems are all closed systems with lane barriers. Compared with traditional manual toll collection, they can improve lane capacity, reduce payment service time, and achieve energy conservation and emission reduction effects. However, this model has the disadvantages of high civil construction costs for toll stations, relatively low speed due to toll islands, and abnormal transactions or illegal vehicles that require on-site manual processing. In order to adapt to barrier-free passage and toll collection on highways and urban roads, a technology called multi-lane free-flow electronic toll collection is proposed.

[0003] Multi-lane free-flow electronic toll collection means that there are no lane separation facilities at the toll station. The toll collection facilities are set up above the lane or on the gantry on the side of the road. The toll transaction is completed through wireless communication with the on-board terminal installed on the passing vehicle. Vehicles can pass through the toll station at normal speed and in any manner (including by lane, across lanes and changing lanes).

[0004] The existing on-board terminals (OBU) face the following challenges in a multi-lane free-flow application environment:

[0005] First, the existing dedicated short-range communication (DSRC) standard does not support concurrent communication mechanisms at the protocol level. The GB / T20851-2007 series of ETC national standards stipulates a time division multiple access (TDMA) communication protocol, which does not support a roadside terminal (RSU) communicating with multiple vehicle terminals at the same time. Figure 1 As shown in the figure, each roadside terminal covers one lane. The communication transaction is half-duplex, and there is a conversion time between the uplink and downlink links, that is, the roadside terminal cannot receive the uplink signal at the same time when transmitting. Since the DSRC signal is ASK or FSK modulation, if the roadside terminal receives uplink data frames that arrive at the same time or have partial overlap, it cannot parse them separately. Therefore, the roadside terminal of the ETC gantry system generally uses a multi-lane antenna to send downlink data frames in a timed round-robin manner, so as to achieve the purpose of full coverage of multiple lanes, such as Figure 2As shown in the figure, the roadside terminal in the ETC gantry system broadcasts the beacon service table data in a polling manner. The vehicle terminal in the corresponding area of ​​the roadside terminal is awakened by the 14K square wave signal in the beacon service table data and starts to process the beacon service table data and reply to the corresponding vehicle service table data. After receiving the vehicle service table data signal, the roadside terminal establishes a link relationship with the vehicle terminal and starts to interact. The interaction process between the roadside terminal and the vehicle terminal in the ETC gantry system is as follows Figure 3 As shown in the figure, the interaction process between the roadside terminal of the existing ETC gantry system and the composite pass card in the vehicle terminal is as follows Figure 4 As shown, the existing interactive solution can only establish a link with one vehicle-mounted terminal at the same time for transaction, and the transaction efficiency of the vehicle-mounted terminal is not high.

[0006] Secondly, according to the Technical Requirements for Highway Composite Pass Cards (CPC) (Trial), the receiving sensitivity of highway composite pass cards is less than or equal to -65dBm, and the awakening sensitivity is less than or equal to -50dBm. Therefore, the transaction area of ​​highway composite pass cards is relatively large, and usually there will be more highway composite pass cards in the transaction area of ​​the ETC gantry system. After being awakened by the beacon service table of the same channel, more highway composite pass cards and vehicle terminals will reply to the vehicle service table of the same channel. At this time, there will be a problem of collision and interference between the vehicle service table data replied by multiple vehicle terminals and highway composite pass cards, which will affect the reception of the roadside terminal, thereby affecting the overall transaction efficiency of the ETC gantry.

[0042] Various aspects and features of the present disclosure are described herein with reference to the drawings.

[0043] It should be understood that various modifications may be made to the embodiments of the present application. Therefore, the above description should not be considered as limiting, but only as an example of an embodiment. Other modifications within the scope and spirit of the present disclosure will occur to those skilled in the art.

[0044] The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the present disclosure and, together with the general description of the present disclosure given above and the detailed description of the embodiments given below, serve to explain the principles of the present disclosure.

[0045] These and other characteristics of the present disclosure will become apparent from the following description of a preferred form of embodiment given as a non-limiting example, with reference to the attached drawings.

[0046] It should also be understood that, although the present disclosure has been described with reference to some specific examples, those skilled in the art will be able to realize many other equivalent forms of the present disclosure that have the features described in the claims and are therefore within the scope of protection defined thereby.

[0047] The above and other aspects, features and advantages of the present disclosure will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0048] Specific embodiments of the present disclosure are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments claimed are merely examples of the present disclosure, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid obscuring the present disclosure with unnecessary or redundant details. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as a basis and representative basis for the claims to teach those skilled in the art to use the present disclosure in a variety of ways with substantially any suitable detailed structure.

[0049] This specification may use the phrases "in one embodiment," "in another embodiment," "in a further embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present disclosure.

[0050] ETC transactions are realized by wireless communication between the roadside terminal (RoadSideUnit, RSU) and the on-board terminal (or on-board unit, OBU) of the ETC system. The communication protocol adopts the dedicated short-range communication (DSRC) protocol. The processing process is as follows: the roadside terminal periodically transmits downlink (BST, BeaconServiceTable) data signal. When a vehicle equipped with the on-board terminal enters the ETC charging area, it receives the beacon service table data signal and returns the vehicle service table (VST, VehicleServiceTable) data signal.

[0051] The beacon service table data here is generally a set of parameters necessary for communication between the vehicle terminal and the roadside terminal, wherein the parameters include: transmission media characteristics, frame length, frame interval length, uplink window length, timing parameters and counter parameters, etc. The vehicle service table data signal contains the MAC (Media Access Control) address and other information of the vehicle terminal, wherein the MAC address of the vehicle terminal is the main identification code for communication between it and the roadside terminal. After receiving the uplink DSRC data frame, the roadside terminal distinguishes different vehicle terminals by their MAC addresses; the downlink data frames sent by the roadside terminal to different vehicle terminals all use the MAC address of the target vehicle terminal as the dedicated link identifier of the downlink data frame, and the vehicle terminal only receives downlink data frames whose dedicated link identifier is the same as its own MAC address.

[0052] like Figure 3 As shown in the figure, the typical process of existing ETC transactions is as follows: after the roadside terminal receives the vehicle service table (VST) data signal, it first performs encrypted authentication with the on-board terminal, such as by sending a GetSecure.rq data frame to obtain vehicle information. The purpose of the authentication is to determine whether the vehicle is equipped with a legally registered on-board terminal. The on-board terminal returns authentication information, such as sending a Transfer Channel.rs data frame. After the authentication is passed, the roadside terminal and the on-board terminal perform several interactive communications to perform ETC charging. Finally, the roadside terminal sends an EVENT.report data frame to end the transaction. However, the existing interactive scheme can only establish a link with one on-board terminal at the same time for transactions, and the on-board terminal transaction efficiency is not high. In addition, in the case of Figure 4 The communication between the composite pass card shown and the roadside terminal may cause collision and interference between the vehicle service table data replied by multiple on-board terminals and the highway composite pass card, which will affect the reception of the roadside terminal and thus affect the overall transaction efficiency of the ETC gantry.

[0053] The first embodiment of the present disclosure provides a processing method for information release, which is applied to roadside terminals, where the roadside terminals correspond to the vehicle-mounted terminals. The roadside terminals here can be, for example, roadside equipment in an ETC gantry system, which can communicate with the vehicle-mounted terminals of different users to release information to the vehicle-mounted terminals, and can build a highly integrated, fully shared, and real-time intelligent management platform, which will be able to provide technical support for related business work and realize information interconnection and exchange, which can save the cost of information transmission between managers and the public, increase communication efficiency, and optimize management effectiveness.

[0054] Figure 5 : is a flowchart of an information processing method for ETC transactions provided by the first embodiment of the present disclosure. The information processing method of this embodiment is applied to a roadside terminal, and specifically includes the following steps:

[0055] S101, controlling the first antenna to broadcast the first beacon service table data in a broadcasting manner through the first channel and the second channel in sequence.

[0056] In this step, the first antenna is controlled to broadcast the first beacon service table data in sequence through the first channel and the second channel. The first beacon service table data (BST) here is used to wake up the vehicle terminal from a dormant state to a working state. Specifically, the first beacon service table data contains a wake-up signal, which can instruct the vehicle terminal to reply corresponding information to the roadside terminal after waking up. The first channel and the second channel here refer to channels of different communication frequency bands.

[0057] In order to enable the roadside terminal to communicate and conduct transactions in parallel with multiple vehicle-mounted terminals at the same time, and to reduce the probability of collision when multiple vehicle-mounted terminals in the area corresponding to each roadside terminal are awakened at the same time and reply to information, it is necessary to establish a corresponding communication path between the vehicle-mounted terminal and the roadside terminal through the first antenna, that is, the first antenna broadcasts the first beacon service table data in sequence through the first channel and the second channel, and different vehicle-mounted terminals reply to corresponding information by receiving the first channel or the second channel of the first beacon service table data.

[0058] S102: After a first predetermined time, control the second antenna to broadcast second beacon service table data in sequence through the first channel and the second channel.

[0059] After controlling the first antenna to broadcast the first beacon service table data sequentially through the first channel and the second channel in step S101, in this step, after a first predetermined time, the second antenna is controlled to broadcast the second beacon service table data sequentially through the first channel and the second channel. The sending time of the second beacon service table data sent by the second antenna is staggered with the sending time of the first beacon service table data sent by the first antenna, so that the two antennas for different lanes will not send data at the same time when broadcasting information, thereby reducing interference between the vehicle-mounted terminals in different lanes when receiving data. The second beacon service table data here can be the same as or different from the first beacon service table data. The first antenna and the second antenna here generally refer to two antennas that send data sequentially. In actual situations, such as Figure 6 As shown, the first antenna to the fourth antenna can send data in sequence via broadcasting.

[0060] Further, in step S101, controlling the first antenna to send the first beacon service table data in a broadcast manner through the first channel and the second channel in sequence includes: controlling the first antenna to send the first beacon service table data through the first channel; and controlling the first antenna to send the first beacon service table data through the second channel after a second predetermined time.

[0061] Specifically, by staggering the sending time of the first beacon service table data sent by the first antenna through the first channel and the second channel, the probability of multiple vehicle-mounted terminals replying messages to the roadside terminal through the same channel can be reduced, thereby avoiding collision interference problems caused by different vehicle-mounted terminals replying to information through the same channel, thereby affecting data reception by the roadside terminal.

[0062] Furthermore, the first predetermined time is greater than the second predetermined time. Here, the first predetermined time is set to be greater than the second predetermined time, that is, the time interval for sending data between different antennas is set to be greater than the time interval for broadcasting data through the same antenna, so that a sufficient time interval can be set for the vehicle-mounted terminal to reply information to different antennas through the corresponding channel, thereby improving channel utilization, and avoiding to the greatest extent the information collision problem that occurs when vehicles on different lanes receive data sent by the roadside terminal and reply to the roadside terminal, while maintaining the communication efficiency between the roadside terminal in the same lane and different vehicle-mounted terminals.

[0063] Furthermore, after receiving the vehicle service table data returned by the vehicle terminal, it also includes:

[0064] Controlling the first antenna to send transaction data to the first vehicle-mounted terminal and the second vehicle-mounted terminal in sequence;

[0065] After a third predetermined time, the second antenna is controlled to sequentially send transaction data to the first vehicle-mounted terminal and the second vehicle-mounted terminal in the corresponding lane.

[0066] It should be noted that the first antenna is controlled to send transaction data to the first vehicle terminal and the second vehicle terminal in sequence. The transaction data is the communication data after the communication link is established and does not have a wake-up signal. The first vehicle terminal and the second vehicle terminal here are respectively awakened by the first beacon service table data or the second beacon service table data signal of different channels.

[0067] In order to conduct parallel transactions with the vehicle terminals of multiple vehicles in the same lane and reduce the collision probability of multiple vehicle terminals receiving transaction data in the transaction area, the first antenna needs to send transaction data to the first vehicle terminal and the second vehicle terminal in sequence instead of sending transaction data at the same time.

[0068] Here, the first antenna and the second antenna generally refer to two antennas that send data in sequence. Figure 7 As shown, the first antenna to the fourth antenna can send transaction data in a broadcasting manner in sequence.

[0069] Furthermore, for different lanes, after the third predetermined time, the second antenna is controlled to sequentially send transaction data to the first vehicle terminal and the second vehicle terminal in the corresponding lane. By setting the third predetermined time interval between the time when the first antenna and the second antenna send transaction data, the second antenna sends the second transaction data at a different time from the first antenna sends the first transaction data so as not to send them at the same time, thereby reducing mutual interference between antennas in different lanes to affect the reception of transaction data. Here, it is presumed that the vehicle terminal of each vehicle is, for example, a dual-chip vehicle terminal or a composite pass card.

[0070] Further, the controlling the first antenna to send transaction data to the first vehicle-mounted terminal and the second vehicle-mounted terminal in sequence includes:

[0071] Controlling the first antenna to send first transaction data to the first vehicle-mounted terminal;

[0072] After a fourth predetermined time, the first antenna is controlled to send second transaction data to the second vehicle-mounted terminal.

[0073] It should be noted that the first antenna sends transaction data through the first channel and the second channel at different times, which can reduce the problem of multiple vehicle-mounted terminals in the same lane receiving transaction data and interfering with each other, affecting the efficiency of completing transactions between the roadside terminal and the vehicle-mounted terminal.

[0074] Furthermore, during the transaction between the first antenna and the vehicle-mounted terminal, if there is an unoccupied channel, different beacon service table data can be sent based on the unoccupied channel at the same time. In this way, the two different channels cannot be fully utilized to send transaction data and beacon service table data simultaneously or alternately, which further improves channel utilization and increases the success rate of ETC transactions.

[0075] Furthermore, the third predetermined time is greater than the fourth predetermined time. Here, the third predetermined time is set to be greater than the fourth predetermined time, that is, the time interval for sending transaction data between different antennas is set to be greater than the time interval for broadcasting data through the same antenna, so that sufficient time interval can be set for the vehicle terminals in different lanes to complete transactions through corresponding channels, improve channel utilization, and avoid information collision problems that occur during transactions between vehicles in different lanes to the greatest extent, while maintaining the transaction efficiency between the roadside terminal in the same lane and different vehicle terminals.

[0076] Furthermore, the third predetermined time is greater than the first predetermined time. By setting the third predetermined time to be greater than the first predetermined time, a larger time interval is set for transactions between the roadside terminal and the vehicle terminal relative to the processing of the wake-up signal by the different vehicle terminals, which can further improve channel utilization, reduce the possibility of data collision, and increase the transaction success rate between the roadside terminal and the vehicle terminal.

[0077] like Figure 6 and Figure 7 As shown, Figure 6 A timing diagram of beacon service table data sent to roadside terminals on different channels. Figure 7 Timing diagram of transaction data sent to different channels for roadside terminals.

[0078] The following is a specific description of the application scenario of the ETC gantry system with four antennas.

[0079] Scenario 1, such as Figure 6 As shown: Taking the ETC gantry system with 4 antennas as an example, the roadside terminals in different lanes send beacon service table data in a manner that multiple antennas corresponding to different lanes broadcast the beacon service table data in a round-robin manner based on different channels in turn, and each antenna first sends the beacon service table data based on the first channel, and then sends the beacon service table data based on the second channel after the second predetermined time interval. The switching interval time for different antennas to send beacon service table data is the sum of the first predetermined time and the second predetermined time.

[0080] Specifically, the first antenna starts to send the first beacon service table data based on the first channel, and after a second predetermined time interval, the first antenna continues to send the first beacon service table based on the second channel; after the first predetermined time interval, the second antenna sends the second beacon service table data based on the first channel, and after the second predetermined time interval, the second antenna continues to send the second beacon service table data based on the second channel; after the first predetermined time interval, the third antenna sends the third beacon service table data based on the first channel, and after the second predetermined time interval, the third antenna continues to send the third beacon service table data based on the second channel, and so on, until the fourth antenna finishes sending and continues to send by the first antenna.

[0081] Scenario 2, such as Figure 7 As shown: Taking the ETC gantry system with 4 antennas as an example, the processing method for parallel transactions between the roadside terminal and the vehicle-mounted terminal is that when one of the vehicle-mounted terminals is awakened and replies to the vehicle service table data, the roadside terminal starts transactions with it, and when the roadside terminal conducts transactions with the vehicle-mounted terminals of at least two vehicles based on 2 different channels, the roadside terminal uses multiple antennas to send transaction data interacting with the two vehicle-mounted terminals in a round-robin manner, the interval time for the same antenna to send transaction data interacting with the two vehicle-mounted terminals is the fourth predetermined time, and the switching interval time for different antennas to send transaction data is the sum of the third predetermined time and the fourth predetermined time.

[0082] Specifically, the first antenna starts to send the first transaction data to the first vehicle-mounted terminal in the corresponding lane based on the first channel, and after a fourth predetermined time interval, the first antenna continues to send the second transaction data to the second vehicle-mounted terminal in the corresponding lane based on the second channel; after a third predetermined time interval, the second antenna sends the first transaction data to the first vehicle-mounted terminal in the corresponding lane based on the first channel, and also after a fourth predetermined time interval, the second antenna continues to send the second transaction data to the second vehicle-mounted terminal in the corresponding lane based on the second channel; after the third predetermined time interval, the third antenna sends the first transaction data to the first vehicle-mounted terminal in the corresponding lane based on the first channel, and also after a fourth predetermined time interval, the third antenna continues to send the second transaction data to the second vehicle-mounted terminal in the corresponding lane based on the second channel, and so on, until the fourth antenna finishes sending and then the first antenna continues to send.

[0083] The disclosed embodiment can simultaneously communicate and trade with multiple vehicle-mounted terminals based on different lanes, thereby improving information processing efficiency, reducing the probability of collision when multiple vehicle-mounted terminals in a transaction area are awakened at the same time and reply to information, and improving transaction success rate.

[0090] Furthermore, the first predetermined time is greater than the second predetermined time.

[0091] It also includes a third sending module and a fourth sending module, wherein, after receiving the vehicle service table data returned by the vehicle terminal, the third sending module is used to control the first antenna to send transaction data to the first vehicle terminal and the second vehicle terminal in the corresponding lane in sequence; the fourth sending module is used to control the second antenna to send transaction data to the first vehicle terminal and the second vehicle terminal in the corresponding lane in sequence after a third predetermined time.
