[0024] The embodiments of the present disclosure provide a method, a monitoring device and an operation and maintenance device for monitoring the V2X communication status, the method comprising: monitoring the air interface of at least one of a vehicle and a roadside device; when a receiving and sending event of a data frame to be sent and received is monitored on the air interface, obtaining the data frame to be sent and received; according to a preset signature verification function on and off state, verifying the signature of the data frame to be sent and received and then parsing it or parsing the data frame to be sent and received without verification to obtain information to be sent and received; and displaying the information to be sent and received differentially according to the difference in information type of the information to be sent and received.

[0025] The executor of the above method may be a third-party monitoring device that is different from the vehicle and the roadside equipment. The monitoring device does not affect the normal operation of the vehicle and the roadside equipment, and monitors the air interface of at least one of the vehicle and the roadside equipment. When a receiving and sending event is monitored, the data frame to be sent and received corresponding to the receiving and sending event is obtained, and the data frame to be sent and received is verified according to the preset on / off state of the verification function, and then parsed or processed, to obtain the information to be sent and received; the information to be sent and received is displayed differentially according to the difference in information type of the information to be sent and received, so that the normal state and the abnormal state of the information to be sent and received can be displayed differently, which is helpful to quickly locate the position of the communication link abnormality and determine the cause of the abnormality, and promote the timely recovery of V2X communication.

[0026] The above-mentioned monitoring device can be used as an operation and maintenance device or as a functional module of the operation and maintenance device, or the above-mentioned monitoring device and the operation and maintenance device are connected by communication (wireless communication, wired communication, etc.) and / or electrical means (connection between circuits). The operation and maintenance device can determine whether there is a communication anomaly based on the V2X communication status of the data frame to be sent and received monitored by the above-mentioned monitoring device, and prompt the operation and maintenance personnel to handle the operation and maintenance object with communication anomaly or automatically perform operation and maintenance processing on the abnormal operation and maintenance object according to the preset processing logic (in the operation and maintenance system), thereby prompting the operation and maintenance personnel or the operation and maintenance system to repair the abnormal V2X communication link in time.

[0027] In the embodiments of the present disclosure, the term "air interface" is used in a broad sense and refers to a method of connecting two objects through wireless communication. The air interface defines the usage frequency and bandwidth of each wireless channel, or defines the coding method used. The above-mentioned air interface (which may be referred to as air interface) can be a PC5 interface (direct communication interface) in the field of Internet of Vehicles, or it can be a Uu interface (cellular network communication interface).

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0029] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0030] Figure 1 The system architecture of the method for monitoring the V2X communication status applicable to the embodiment of the present disclosure is schematically shown.

[0031] Reference Figure 1 As shown, the system architecture 100 of the method for monitoring the V2X communication status applicable to the embodiment of the present disclosure includes: a roadside device 110, a vehicle 120 and a monitoring device 130.

[0032] The roadside equipment 110 may be various devices arranged on the road side for communicating with the vehicle, such as a base station 111, or various forms of roadside camera devices 112 (including cameras, ranging / speed measuring radars, etc.). The above-mentioned roadside equipment may realize communication with the on-board unit (OBU) in the vehicle based on the roadside unit (RSU).

[0033] For example, the on-board unit (OBU) and the roadside unit (RSU) communicate through the PC5 interface (or air interface), which is called V2I (Vehicle to Infrastructure) communication.

[0034] Vehicles communicate with each other through the PC5 interface of the OBU, which is called V2V (Vehicle to Vehicle) communication.

[0035] The OBU communicates with the LTE (a type of mobile communication base station) base station through the Uu port, which is called V2N (Vehicle to Network) communication.

[0036] PC5 is used to broadcast V2I messages and receive V2V messages (messages can also be described as information). It also serves as a data gateway for other roadside devices (such as cameras, radars, etc.), sending data from other roadside devices to the cloud V2X application server via Uu or wired methods.

[0037] The on-board unit is a V2X on-board terminal that supports two communication modes, PC5 and Uu. PC5 is used to broadcast V2V messages and receive V2I messages, and Uu can send vehicle-side data to the cloud V2X application server.

[0038] The embodiment of the present disclosure proposes a monitoring device 130, which is used to execute the V2X communication status monitoring method proposed in the embodiment of the present disclosure, by monitoring the air interface of at least one of the vehicle and the roadside device, and when monitoring the receiving and sending event, obtaining the to-be-received data frame corresponding to the receiving and sending event, and verifying the signature of the above-mentioned data frame according to the preset on-off state of the signature verification function, and then parsing and processing it, or parsing and processing the above-mentioned data frame without verification, to obtain the to-be-received information; according to the difference in information type of the above-mentioned information to be sent and received, the above-mentioned information to be sent and received is displayed differentially, so that the normal state and the abnormal state of the information to be sent and received can be displayed separately, which is helpful to quickly locate the position of the communication link abnormality and determine the cause of the abnormality, and promote the timely recovery of V2X communication.

[0039] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0040] A first exemplary embodiment of the present disclosure provides a method for monitoring a V2X communication status.

[0041] Figure 2 The flowchart of the method for monitoring the V2X communication status according to an embodiment of the present disclosure is schematically shown.

[0042] Reference Figure 2 As shown, the method for monitoring the V2X communication status provided by the embodiment of the present disclosure includes the following steps: S210, S220, S230 and S240. The above steps S210 to S240 can be performed by Figure 1 The monitoring device 130 shown in the example is used for execution.

[0043] In step S210, an air interface of at least one of a vehicle and a roadside device is monitored.

[0044] The above-mentioned air interface is, for example, a PC5 air interface.

[0045] In step S220, when it is monitored that there is a sending / receiving event of a data frame to be sent / received on the air interface, the data frame to be sent / received is acquired.

[0046] For example, when vehicles communicate with each other or vehicles with roadside equipment based on the PC5 air interface, the monitoring device 130 can obtain the data frames to be sent and received during the communication process by monitoring the sending and receiving events occurring at the air interface (e.g., the PC5 air interface) of the vehicle and the roadside equipment, and then obtain the information to be sent and received by executing the subsequent step S230, and execute step S240 to differentially display the above-mentioned information to be sent and received, so that the operation and maintenance personnel or the operation and maintenance equipment can determine the communication status of the vehicle and the roadside equipment based on the displayed information to be sent and received.

[0047] In an embodiment of only monitoring the air interface of the vehicle (or the roadside equipment), it is possible to obtain data frames to be sent or received between vehicles or data frames to be sent or received by the vehicle to the roadside equipment by monitoring the air interface of the vehicle (or the corresponding roadside equipment) (in the case of roadside equipment, it corresponds to data frames to be sent or received between the roadside equipment and the vehicle), and by executing subsequent steps S230 and S240, differentiated display is performed according to the information type of the information to be sent or received obtained by the analysis.

[0048] If the sent and received information identified only through the interface on one side of the vehicle or roadside equipment fails the signature verification, it means that the communication of a specific vehicle or a specific roadside equipment may be abnormal, and a comprehensive judgment needs to be made based on the communication data from multiple sides and parties.

[0049] In some cases, it is usually necessary to determine whether the anomaly is caused by the specific vehicle S or by a specific roadside device L. For the determination of the communication status of a specific vehicle S, it is necessary to further combine other relevant data. For example, it is possible to determine whether the specific vehicle S has a communication anomaly by obtaining the communication status between other vehicles and the specific vehicle S in addition to the data frames to be sent and received by the current vehicle monitored; in addition, it is also possible to determine whether the specific vehicle S has a communication anomaly by combining the communication status between the roadside devices (such as multiple roadside devices L, R, T, etc.) and the specific vehicle S in the same period.

[0050] In addition, the above-mentioned air interface is exemplified by the PC5 interface, and the above-mentioned air interface can also be a Uu interface. For example, the data frames to be sent and received by the vehicle to the server (such as the RTK cloud computing server) can also be monitored.

[0051] In step S230, according to the preset on / off status of the signature verification function, the data frame to be sent or received is verified for signature and then parsed, or the data frame to be sent or received is parsed without verification to obtain the information to be sent or received.

[0052] The preset on / off state of the signature verification function may be preset by the user of the monitoring device (a person who is registered on the monitoring device and has the authority to set the signature verification function, for example, the user may be an operation and maintenance personnel).

[0053] In step S240, the information to be sent or received is displayed in a differentiated manner according to the information types of the information to be sent or received.

[0054] Based on the above steps S210 to S240, by monitoring the air interface of at least one of the vehicle and the roadside equipment, and when a receiving and sending event is monitored, the to-be-received data frame corresponding to the receiving and sending event is obtained, and the to-be-received data frame is verified according to the preset on / off state of the verification function and then parsed or the to-be-received data frame is parsed without verification to obtain the to-be-received information; the to-be-received information is displayed differentially according to the difference in information type of the to-be-received information, so that the normal state and the abnormal state of the to-be-received information can be displayed distinguishably, which helps to quickly locate the position of the communication link abnormality and determine the cause of the abnormality, and promote the timely recovery of V2X communication.

[0055] Figure 3 The detailed implementation flow chart of step S230 of the embodiment of the present disclosure is schematically shown.

[0056] According to the embodiments of the present disclosure, referring to Figure 3 As shown, in the above step S230, according to the preset on / off status of the signature verification function, the above data frames to be sent and received are verified and then parsed or the above data frames to be sent and received are parsed without verification to obtain the information to be sent and received, including the following steps: S310 or S320.

[0057] In step S310, when the signature verification function is turned on, the data frame to be sent or received is verified and then parsed to obtain the information to be sent or received.

[0058] In step S320, when the signature verification function is in a closed state, the data frame to be sent or received is parsed without signature verification to obtain the information to be sent or received.

[0059] According to an embodiment of the present disclosure, in the above step S310, the data frame to be sent or received is verified for signature and then parsed to obtain the information to be sent or received, including the following sub-steps: S311, S312a and S312b.

[0060] In sub-step S311, the digital signature of the data frame to be sent or received is verified.

[0061] In sub-step S312a, when the digital signature of the data frame to be sent or received passes the verification, the data frame to be sent or received is parsed to obtain the parsed information to be sent or received.

[0062] In sub-step S312b, when the digital signature verification of the above-mentioned data frame to be sent or received fails, the above-mentioned data frame to be sent or received is parsed to obtain the parsed information to be sent or received, and a special mark is added to the above-mentioned information to be sent or received, and the above-mentioned special mark is used to indicate the status that the digital signature verification of the above-mentioned data frame to be sent or received fails.

[0063] Figure 4 The detailed implementation flow chart of step S240 of the embodiment of the present disclosure is schematically shown.

[0064] According to the embodiments of the present disclosure, referring to Figure 4 As shown, in the above step S240, the above information to be sent or received is displayed differentially according to the information type difference of the above information to be sent or received, including the following steps: S410 and S420.

[0065] In step S410, for each piece of information to be sent or received, a target display style corresponding to the information type of each piece of information to be sent or received is determined according to a preset mapping relationship between the information type and the display style.

[0066] In step S420, each piece of information to be sent or received is displayed accordingly based on the target display style.

[0067] According to an embodiment of the present disclosure, the information types in the above mapping relationship include: basic safety information (BSM) type, roadside information (RSI) type, roadside safety information (RSM) type, traffic light phase and timing information (SPAT) type, and map information (MAP) type.

[0068] The target display styles corresponding to different information types differ in at least one display attribute (e.g., display color, display font, display background pattern, etc.), and when the information to be sent or received carries a special mark, the target display style of the information to be sent or received is a warning display style, and the warning display style is used to indicate the abnormal state of the information to be sent or received. For example, the warning display style is the information to be sent or received with a red exclamation mark.

[0069] A second exemplary embodiment of the present disclosure provides a device for monitoring an air data frame.

[0072] The V2X communication module 501 is used to monitor the air interface of at least one of the vehicle and the roadside equipment.

[0073] The above-mentioned V2X communication module 501 is also used to obtain the above-mentioned data frames to be sent or received when monitoring the sending or receiving events of the above-mentioned air interface.

[0074] The processing module 502 is used to call the V2X security module 503 to verify the signature of the data frame to be sent and received, and then parse and process the data frame to be sent and received, or parse and process the data frame to be sent and received without verification, according to the preset signature verification function on and off status, to obtain the information to be sent and received.

[0075] The display module 504 is used to display the information to be sent or received in a differentiated manner according to the information types of the information to be sent or received.

[0076] According to the embodiments of the present disclosure, referring to Figure 5 As shown, the monitoring device 500 further includes: a power supply module 505, which is connected to the V2X communication module 501, the processing module 502, the V2X security module 503 and the display module 504, and is used to supply power to the V2X communication module 501, the processing module 502, the V2X security module 503 and the display module 504.

[0077] According to an embodiment of the present disclosure, when the signature verification function is in the turned-on state, the above-mentioned processing module 502 calls the above-mentioned V2X security module 503 to verify the signature of the above-mentioned data frame to be sent and received, and obtains the signature verification result; the above-mentioned processing module 502 parses and processes the above-mentioned data frame to be sent and received according to the above-mentioned signature verification result to obtain the information to be sent and received.

[0078] When the signature verification function is in a disabled state, the processing module 502 parses and processes the data frame to be sent or received without signature verification to obtain the information to be sent or received.

[0079] According to an embodiment of the present disclosure, the processing module 502 parses and processes the data frame to be sent and received according to the signature verification result to obtain the information to be sent and received, including: when the signature verification result is that the digital signature verification of the data frame to be sent and received is passed, the processing module parses and processes the data frame to be sent and received to obtain the parsed information to be sent and received; when the signature verification result is that the digital signature verification of the data frame to be sent and received fails, the processing module parses and processes the data frame to be sent and received to obtain the parsed information to be sent and received, and marks the information to be sent and received with a special mark, and the special mark is used to indicate the state that the digital signature verification of the data frame to be sent and received fails.

[0080] According to an embodiment of the present disclosure, the above information types include: basic safety information (BSM) type, roadside information (RSI) type, roadside safety information (RSM) type, traffic light phase and timing information (SPAT) type, map information (MAP) type. The target display styles corresponding to different information types differ in at least one display attribute (such as display color, display font, display background pattern, etc.), and when the above information to be sent or received carries a special mark, the target display style of the above information to be sent or received is a warning display style, and the above warning display style is used to prompt the abnormal state of the above information to be sent or received.

[0081] A third exemplary embodiment of the present disclosure provides an operation and maintenance device.

[0082] The operation and maintenance device includes the monitoring device described above, or communicates with and / or is electrically connected to the monitoring device described above. The operation and maintenance device is used to determine whether there is a communication anomaly based on the V2X communication status of the data frame to be sent and received monitored by the monitoring device, and to prompt the operation and maintenance personnel of the operation and maintenance object with communication anomaly for processing or automatically perform operation and maintenance processing on the operation and maintenance object with abnormality according to the preset processing logic.

[0083] For example, in one embodiment, when the data frame to be sent or received carries a special identifier, the above-mentioned operation and maintenance equipment will mark the abnormal object (for example, a roadside device) corresponding to the above-mentioned data frame to be sent or received as abnormal, and prompt the operation and maintenance personnel to inspect and handle the roadside equipment corresponding to the abnormality; or in another embodiment, when the data frame to be sent or received carries a special identifier (for example, the vehicle's certificate is expired, the certificate type / authority is incorrect, the signature verification fails, etc.), the above-mentioned operation and maintenance equipment will mark the abnormal object (for example, vehicle A) corresponding to the above-mentioned data frame to be sent or received as abnormal, and automatically make a comprehensive judgment on the communication status of the above-mentioned vehicle A. For example, it can be based on the monitoring results of the communication between other vehicles and vehicle A to comprehensively judge whether vehicle A is indeed in a communication abnormality state, and when the comprehensive judgment result of vehicle A is in a communication abnormality, the security certificate of vehicle A is promptly marked as invalid or a behavior control strategy is adopted for vehicle A, etc., to ensure that other vehicles no longer trust the data of vehicle A and avoid the harm of vehicle A to other moving vehicles.
