Description

Technical Field

[0001] The present application belongs to the field of intelligent transportation technology, and in particular relates to a signal response control method, device, electronic device and readable storage medium. Background Art

[0002] With the development and maturity of 5.8GHz dedicated short-range communication (DSRC) technology, its services have been widely used in transportation and highway toll collection. In the current Electronic Toll Collection (ETC) system, the roadside unit (RSU) uses DSRC technology to communicate with the on-board unit (OBU) to implement functions such as vehicle identification and electronic point deduction. The OBU is a device installed on the vehicle that supports information exchange with the RSU. OBUs that comply with the current "Dedicated Short-Range Communication for Electronic Toll Collection" (GB / T20851) are called OBU1.0. OBUs with dedicated physical channels to implement extended vehicle-road collaborative application functions are called OBU2.0. RSUs that can support both toll collection services and basic service scenarios through software upgrades are called RSU1.5. Road test units that support both toll collection services and have dedicated physical channels to implement extended vehicle-road collaborative service functions are called RSU2.0.

[0003] Based on DSRC technology, RSU2.0 broadcasts BST signals, using FSK modulation and ASK modulation respectively. After OBU2.0 receives the signals using FSK modulation and ASK modulation, it replies with the response signal of the corresponding modulation mode. In this process, signal interference is likely to occur between the FSK modulation signal and the ASK modulation signal, which seriously affects the efficiency and accuracy of transactions between RSU and OBU. Summary of the Invention

[0004] The present application provides a signal response control method, device, electronic device and readable storage medium, which can solve the technical problem of mutual interference between FSK signals and ASK signals during communication between RSU and OBU.

[0005] A first aspect of an embodiment of the present application provides a signal response control method, which is applied to a vehicle-mounted unit. The signal response control method includes:

[0006] Upon receiving a charging ASK signal and an extended service FSK signal sent by a roadside unit in the same time period, responding to the charging ASK signal and suppressing responding to the extended service FSK signal;

[0007] After the onboard unit completes the charging transaction, it resumes responding to the extended service FSK signal.

[0008] A second aspect of the present application further provides a signal response control device, which is configured in a vehicle-mounted unit and includes:

[0009] a response suppression control unit, configured to, upon receiving a charging ASK signal and an extended service FSK signal sent by a roadside unit in the same time period, respond to the charging ASK signal and suppress responding to the extended service FSK signal;

[0010] The recovery response control unit is used to recover the response to the extended service FSK signal after the on-board unit completes the charging transaction.

[0011] A third aspect of an embodiment of the present application provides an electronic device, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the computer program, when executed by the processor, implements the steps of the signal response control method described in the first aspect above.

[0012] A fourth aspect of an embodiment of the present application provides a computer-readable storage medium, which stores a computer program. When the computer program is executed by a processor, the steps of the signal response control method described in the first aspect are implemented.

[0013] A fifth aspect of an embodiment of the present application provides a computer program product, which includes a computer program. When the computer program is executed by a processor, the steps of the signal response control method described in the first aspect are implemented.

[0014] In an embodiment of the present application, when the on-board unit receives the toll ASK signal and the extended service FSK signal sent by the roadside unit in the same time period, it responds to the toll ASK signal first and suppresses the response to the extended service FSK signal, that is, it does not send the FSK response signal; after the on-board unit completes the toll transaction, it resumes the response to the extended service FSK signal, thereby realizing the time-sharing response of the ASK signal and the FSK signal. Therefore, the situation where the OBU transmits the FSK response signal, resulting in a decrease in the OBU's receiving sensitivity to the toll ASK signal will not occur, thereby solving the technical problem of mutual interference between the FSK signal and the ASK signal during the communication between the RSU and the OBU, so that the on-board unit can successfully complete the ETC toll function and the extended service function on the road section where the toll ASK signal and the extended service FSK signal exist at the same time, thereby improving the success rate of the ETC transaction.

[0023] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0024] It should be understood that in this specification and the appended claims, the term "comprising" indicates the presence of described features, wholes, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or collections thereof.

[0025] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0026] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized.

[0027] With the development and maturity of 5.8GHz dedicated short-range communication (DSRC) technology, its services have been widely used in transportation and highway toll collection. In current electronic toll collection (ETC) systems, roadside units (RSUs) use DSRC technology to communicate with on-board units (OBUs) to implement functions such as vehicle identification and electronic point deduction.

[0028] The on-board unit (OBU) is a device installed on the vehicle that supports information exchange with roadside units (ROUs). OBUs that comply with the current "Specialized Short-Range Communications for Electronic Toll Collection" (GB / T20851) are called OBU1.0, while OBUs with dedicated physical channels for expanded vehicle-road collaboration applications are called OBU2.0. RSUs that can support both toll collection and basic service scenarios through software upgrades are called RSU1.5. Road test units that support both toll collection and dedicated physical channels for expanded vehicle-road collaboration services are called RSU2.0.

[0029] like Figure 1 As shown in FIG, in the ETC communication system, when RSU 1.5 communicates with OBU 1.0, RSU 1.5 broadcasts an ASK (Amplitude Shift Keying) modulated charging ASK signal to the passing vehicles, and OBU 1.0 replies with an ASK modulated ASK response signal to RSU 1.5 according to the received charging ASK signal.

[0030] like Figure 2 As shown in FIG, when RSU2.0 communicates with OBU2.0, RSU2.0 broadcasts an ASK-modulated charging ASK signal and an FSK-modulated extended service FSK signal to the passing vehicles, and OBU2.0 replies with an ASK-modulated ASK response signal and an FSK-modulated FSK signal to RSU2.0 according to the received charging ASK signal.

[0031] In an embodiment of the present application, the charging ASK signal may include: a BST signal, a getsecure signal, a trafficinfo signal and an eventreport signal. The extended service FSK signal may also include: a BST signal, a getsecure signal, a trafficinfo signal and an eventreport signal. Among them, the BST (Beacon Service Table) signal refers to the beacon service table sent by the roadside unit to the OBU, which is used to transmit system-level parameters (such as lane information, transaction rules, time synchronization, etc.) for the on-board unit (OBU) to receive and initialize communication. The getsecure signal refers to a security service request / security authentication signal, which is used for security-related interactions (such as key exchange, data encryption verification), triggering the OBU to execute the security authentication process, and ensuring the legitimacy of the communication (for example, preventing counterfeit OBU attacks). The trafficinfo signal refers to a traffic information signal, which is used to transmit real-time traffic data (such as congestion, accidents, construction, etc.), dynamically adjust charging strategies or provide road condition information to drivers. The eventreport signal is used to indicate the termination of the communication process, and no other signals will be processed subsequently.

[0032] It should be noted that since the extended service FSK signal is used for real-time broadcast of highway traffic information and auxiliary strategy prompts, the communication distance of the extended service FSK signal is 800m-1000m, while the communication distance of the toll ASK signal is shorter, usually within 100m. Therefore, the priority of OBU2.0 responding to the toll ASK signal needs to be higher than the priority of responding to the extended service FSK signal.

[0033] above Figure 1 and Figure 2 The main difference between the two types of RSU and OBU communication is whether the RSU and OBU can send and receive FSK modulated signals. RSU2.0 and OBU2.0 are RSU and OBU that can send and receive FSK modulated signals.

[0034] like Figure 3As shown, for communication between RSU2.0 and OBU2.0, RSU2.0 broadcasts an ASK-modulated charging ASK signal and an FSK-modulated extended service FSK signal to the passing vehicle. When the OBU responds to the charging ASK signal and the extended service FSK signal, since the priority of OBU2.0 in responding to the charging ASK signal is higher than the priority of responding to the extended service FSK signal, the OBU transmits the ASK response signal used to respond to the charging ASK signal before sending the FSK response signal in response to the extended service FSK signal. In this case, due to the small size of the OBU and the isolation that cannot meet the signal anti-interference requirements, when the OBU transmits the FSK response signal, the OBU's receiving sensitivity to the charging ASK signal is affected, resulting in signal interference between the FSK signal (i.e., the FSK response signal) and the ASK signal (i.e., the charging ASK signal), which reduces the success rate of ETC transactions.

[0035] Based on this, the embodiments of the present application provide a signal response control method, device, electronic device and readable storage medium. When the on-board unit receives the toll ASK signal and the extended service FSK signal sent by the roadside unit in the same time period, the on-board unit gives priority to responding to the toll ASK signal and suppresses the response to the extended service FSK signal, that is, does not send the FSK response signal; after the on-board unit completes the toll transaction, the response to the extended service FSK signal is restored, that is, the FSK response signal is sent; therefore, there will be no situation where the OBU's receiving sensitivity to the toll ASK signal is reduced due to the OBU transmitting the FSK response signal, which solves the technical problem of mutual interference between the FSK modulation signal and the ASK modulation signal during the communication between the RSU and the OBU, so that the on-board unit can successfully complete the ETC toll function and the extended service function on the road section where the toll ASK signal and the extended service FSK signal exist at the same time, thereby improving the success rate of the ETC transaction.

[0036] In order to facilitate understanding by those skilled in the art, the solutions of the present application are described below by way of examples.

[0037] like Figure 4As shown, it is a structural diagram of the ETC communication system provided in an embodiment of the present application. The ETC communication system may include an ICC card 11, an on-board unit (OBU) 12, a roadside unit (RSU) 13, a lane control system 14 and a background database system 15. The ICC card 11 is used to store the user's account information and payment voucher. The ICC card 11 and the OBU 12 together realize the automatic deduction function. The OBU is usually installed on the front windshield of the vehicle. It is a medium for information exchange between the vehicle and the ETC system. It is used to store vehicle information and communicate with lane sensors and RSUs. The RSU is a key device installed on the roadside in the ETC system. It communicates with the OBU by adopting the DSRC protocol to realize vehicle identity recognition and electronic deduction. The lane control system receives and processes vehicle information from the RSU, and exchanges data with the background server to ensure the accuracy and real-time nature of the vehicle information. The background database system is responsible for data storage, data management and maintenance of the entire system to ensure the stable operation and efficient operation of the ETC system.

[0038] In this embodiment of the present application, the onboard unit 12 may be an OBU2.0 containing an ASK radio frequency chip and an FSK radio frequency chip. It can be deployed on the vehicle via pre-installation or post-installation, and the onboard unit may be an intelligent device that implements signal response using software and / or hardware. The onboard unit can communicate with the roadside unit to provide the vehicle with ETC toll collection functions, as well as extended service functions such as safety assistance and information broadcasting. For example, extended service functions include warning of driving risks on special road sections, warning of traffic on restricted roads, and management of sudden traffic incidents.

[0039] The above-mentioned roadside unit 13 can be a gantry deployed on a high-speed ETC extended service communication section or on both sides of the road, and performs ETC communication with the OBU to realize the vehicle's charging function and extended service function.

[0040] In the current related technologies, when the on-board unit is traveling on a road section where both toll ASK signals and extended service FSK signals exist, a technical problem of mutual interference between FSK signals and ASK signals may easily occur during the communication between the RSU and the OBU.

[0041] Based on this, the embodiment of the present application provides a signal response control method, illustratively, as Figure 5 As shown, it is a schematic diagram of the implementation process of the signal response control method provided in an embodiment of the present application. The signal response control method is applied to the on-board unit in the above-mentioned ETC communication system and can be executed by the signal response control device on the on-board unit, including the following steps 101 to 102.

[0042] Step 101: upon receiving a charging ASK signal and an extended service FSK signal sent by a roadside unit in the same time period, respond to the charging ASK signal and suppress responding to the extended service FSK signal.

[0043] In the embodiment of the present application, there are three situations in which the OBU receives the charging ASK signal and the extended service FSK signal sent by the roadside unit in the same time period. The first situation: the OBU receives the charging ASK signal at the same time while performing the extended service function, that is, the OBU first receives the extended service FSK signal and then receives the charging ASK signal. The second situation: the OBU receives the charging ASK signal and the extended service FSK signal at the same time. The third situation: the OBU first receives the charging ASK signal and then receives the extended service FSK signal. In all three situations, signal interference between the FSK signal (i.e., the FSK response signal) and the ASK signal (i.e., the charging ASK signal) may occur.

[0044] Specifically, since the priority of the charging ASK signal is higher than the priority of the extended service FSK signal, it is necessary to respond to the charging ASK signal first, that is, send an ASK response signal, and then respond to the extended service FSK signal, that is, send an FSK response signal. In actual applications, due to the small size of the OBU and the inability of the isolation to meet the signal anti-interference requirements, when the OBU transmits the FSK response signal, it will affect the OBU's receiving sensitivity to the charging ASK signal, and signal interference between the FSK signal (that is, the FSK response signal) and the ASK signal (that is, the charging ASK signal) will occur, reducing the success rate of the ETC transaction. Therefore, in an embodiment of the present application, when receiving the charging ASK signal and the extended service FSK signal sent by the roadside unit in the same time period, after responding to the charging ASK signal, it is necessary to suppress the response to the extended service FSK signal, that is, the OBU receives the extended service FSK signal but does not send the FSK response signal.

[0045] Step 102: After the onboard unit completes the charging transaction, it resumes responding to the extended service FSK signal.

[0046] Since the OBU does not need to respond to the charging ASK signal temporarily after completing the charging transaction, it can resume responding to the extended service FSK signal, that is, send an FSK response signal to complete the extended service function.

[0047] In the embodiment of the present application, when the on-board unit receives the toll ASK signal and the extended service FSK signal sent by the roadside unit in the same time period, the on-board unit gives priority to responding to the toll ASK signal and suppresses the response to the extended service FSK signal, that is, does not send an FSK response signal; after the on-board unit completes the toll transaction, the response to the extended service FSK signal is restored, thereby realizing a time-sharing response of the toll ASK signal and the extended service FSK signal. Therefore, the situation where the OBU transmits the FSK response signal and causes the OBU to have a reduced receiving sensitivity to the toll ASK signal will not occur, thereby solving the technical problem of mutual interference between the FSK signal and the ASK signal during the communication between the RSU and the OBU, so that the on-board unit can successfully complete the ETC toll function and the extended service function on the road section where the toll ASK signal and the extended service FSK signal exist at the same time, thereby improving the success rate of the ETC transaction.

[0048] like Figure 6 As shown in the figure, in a practical application scenario, the communication process between RSU2.0 and OBU2.0 is as follows: First, RSU2.0 broadcasts a toll collection ASK signal and an extended service FSK signal to passing vehicles. The OBU2.0 on the vehicle receives the toll collection ASK signal and the extended service FSK signal. Based on the higher priority of the response ASK signal, OBU2.0 transmits an ASK response signal while suppressing the OBU response to the extended service FSK signal. That is, OBU2.0 receives the extended service FSK signal but does not send an FSK response signal. The OBU and RSU use ASK signals to establish a communication link and obtain application information. Second, OBU2.0 completes the transaction service, releases the link, ends ASK communication, and releases the FSK signal transmission suppression. Third, OBU2.0 receives the extended service FSK signal. The OBU and RSU use FSK signals to establish a communication link and obtain application information, further completing basic services such as special road driving risk warnings, restricted road traffic warnings, and sudden traffic incident management. After the service is completed, the link is released.

[0049] In one embodiment of the present application, the duration corresponding to the same time period in step 101 is the duration from the moment the onboard unit receives the extended service FSK signal to the moment it prepares to send the FSK response signal.

[0050] Specifically, after the on-board unit receives the extended service FSK signal, it needs to process the received extended service FSK signal before responding to the extended service FSK signal, that is, sending an FSK response signal. From the moment the on-board unit receives the extended service FSK signal to the time it processes the extended service FSK signal and then prepares to send the FSK response signal, the on-board unit may receive the charging ASK signal. After receiving the charging ASK signal, it indicates that the charging service needs to be given priority, that is, the charging ASK signal needs to be responded to first. Therefore, there will be a problem of mutual interference between the FSK signal and the ASK signal. Therefore, when receiving the charging ASK signal and the extended service FSK signal sent by the roadside unit in the same time period, it is necessary to suppress the response to the extended service FSK signal during the response to the charging ASK signal. After the on-board unit completes the charging transaction, the response to the extended service FSK signal can be restored to reduce the mutual interference between the FSK signal and the ASK signal during the communication between the RSU and the OBU, and improve the success rate of ETC transactions.

[0051] In one embodiment of the present application, responding to the charging ASK signal in the above step 101 may refer to establishing a first communication connection with the roadside unit based on the received charging ASK signal, and completing the charging transaction based on the first communication connection.

[0052] For example, after the OBU receives the charging ASK signal, it establishes a communication link (i.e., the first communication connection) with the RSU using the ASK signal, and interacts with information such as OBU data and ICC-PSAM consumption transactions based on the communication link. After the OBU completes the transaction service, it releases the communication link and ends the ASK communication, lifting the suppression of the FSK signal transmission.

[0053] In one embodiment of the present application, suppressing the response to the extended service FSK signal in the above step 101 may refer to stopping sending the FSK response signal to the roadside unit.

[0054] For example, no FSK response signal is sent to the RSU before the OBU completes the toll transaction.

[0055] In order to improve the real-time performance of the extended service function, in one embodiment of the present application, suppressing the response to the extended service FSK signal in the above step 102 may include: stopping sending the FSK response signal to the roadside unit when the on-board unit is waiting to receive the charging ASK signal.

[0056] For example, when the OBU has just finished sending an ASK response signal and is waiting to receive a toll ASK signal from the RSU, it stops sending an FSK response signal to the RSU. When the OBU has just received and is processing the toll ASK signal, it can send an FSK response signal to the RSU. That is, the response to the extended service FSK signal is not suppressed, thereby simultaneously realizing the vehicle's ETC toll collection function and extended service function. In addition, there will be no signal interference between the FSK signal and the ASK signal during the communication process between the RSU and the OBU.

[0057] In one embodiment of the present application, the above step 102 of recovering the response to the extended service FSK signal may include: establishing a second communication connection with the roadside unit based on the extended service FSK signal, and completing the extended service function based on the second communication connection.

[0058] For example, after resuming the response to the extended service FSK signal, if the onboard unit receives the extended service FSK signal again, it will establish a communication link (i.e., a second communication connection) with the roadside unit based on the newly received extended service FSK signal, and complete the extended service function based on the second communication connection. For example, extended service functions such as special road section driving risk warning, specific restricted road section traffic warning, and sudden traffic incident management and control will be completed, and the communication link will be released after the service is completed.

[0059] In one embodiment of the present application, after the duration of resuming the response to the extended service FSK signal is greater than the preset duration, if the on-board unit receives a new charging ASK signal sent by the roadside unit, the on-board unit is controlled to respond to the new charging ASK signal and suppress the response to the extended service FSK signal.

[0060] For example, when a vehicle exits a highway and then re-enters it, or when a certain highway section contains multiple roadside units that need to send toll ASK signals to vehicles in order to implement highway mileage charging and route restoration, the on-board unit may, after completing the previous toll transaction and resuming its response to the extended service FSK signal, receive a new toll ASK signal from the roadside unit again after an interval greater than a preset time. In this case, it is necessary to control the on-board unit to respond to the new toll ASK signal and suppress its response to the extended service FSK signal, that is, to return to executing steps 101 and 102 to resolve the technical problem of interference between FSK modulation signals and ASK modulation signals during communication between the RSU and the OBU. If the on-board unit receives a new toll ASK signal within the preset time after resuming its response to the extended service FSK signal, the new toll ASK signal may be the same as the toll ASK signal from the toll transaction just completed. Therefore, the on-board unit does not need to respond to the toll ASK signal again. Therefore, within the preset duration after resuming the response to the extended service FSK signal, if the OMU receives a new toll collection ASK signal, it can suppress its response to the new toll collection ASK signal, and there is no need to suppress its response to the extended service FSK signal, allowing the OMU to perform the extended service function normally. After the duration of the resumption of the response to the extended service FSK signal exceeds the preset duration, if the OMU receives a new toll collection ASK signal from the roadside unit, it will then control the OMU to respond to the new toll collection ASK signal and suppress its response to the extended service FSK signal, thereby improving the success rate of toll transactions.

[0061] In an embodiment of the present application, in order to solve the problem of signal interference between the FSK response signal transmitted by OBU2.0 and the toll ASK signal received in the communication scenario between OBU2.0 and RSU2.0, a time-sharing response scheme for ASK signals and FSK signals is proposed. That is, when the toll ASK signal and the extended service FSK signal sent by the roadside unit in the same time period are received, the toll ASK signal is responded to first, and the response to the extended service FSK signal is suppressed; after the on-board unit completes the toll transaction, the response to the extended service FSK signal is restored, which effectively solves the problem of signal interference between the FSK signal transmitted by OBU2.0 and the ASK signal received.

[0062] It should be noted that, for the sake of simplicity of description, the aforementioned method embodiments are all expressed as a series of action combinations. However, those skilled in the art should be aware that this application is not limited to the described order of actions. In some embodiments of this application, certain steps may be performed in other orders.

[0065] The recovery response control unit 702 is used to recover the response to the extended service FSK signal after the onboard unit completes the charging transaction.

[0066] In some embodiments of the present application, the above-mentioned suppression response control unit is further used to: establish a first communication connection with the roadside unit based on the charging ASK signal, and complete the charging transaction based on the first communication connection.

[0067] In some embodiments of the present application, the above-mentioned suppression response control unit is further used to: stop sending the FSK response signal to the roadside unit.

[0070] In some embodiments of the present application, the duration corresponding to the same time period is the duration from the moment the onboard unit receives the extended service FSK signal to the moment it prepares to send the FSK response signal.

[0071] In some embodiments of the present application, the above-mentioned recovery response control unit is also used to: after the duration of the recovery response to the extended service FSK signal is greater than the preset duration, if a new charging ASK signal is received, control the on-board unit to respond to the new charging ASK signal and suppress the response to the extended service FSK signal.

[0072] It should be noted that, for the sake of convenience and brevity, the specific working process of the signal response control device described above can be referred to the description of the signal response control method in the above embodiments, and will not be repeated here. It should also be noted that the above embodiments can be combined with each other to obtain a variety of different embodiments, all of which fall within the scope of protection of this application.

[0073] like Figure 8As shown, the embodiment of the present application also provides an electronic device. The electronic device can be configured with the signal response control device shown in each of the above embodiments, and the electronic device can be a vehicle-mounted unit or a car equipped with the vehicle-mounted unit. Figure 8 As shown, the electronic device 8 may include: a processor 80, a memory 81, and a computer program 82 stored in the memory 81 and executable on the processor 80. When the processor 80 executes the computer program 82, the steps in the above-mentioned various signal response control method embodiments are implemented, for example, Figure 5 Steps 101 to 102 are shown.
