Therefore, the tester can complete the test of the V2X network and know the problems in the V2X network only through the V2X message acquisition equipment, so as to realize the operation and maintenance of the V2X network.
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions in the embodiments of the present application are further described in detail by the following embodiments in combination with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Fig. 1 is a schematic structural diagram of a V2X message collection device according to an embodiment of the present application. As shown in fig. 1, the V2X message collection device may include: a plurality of V2X receivers 10 and processors 11; each of the V2X receivers 10 for jointly receiving a V2X message broadcast in a V2X network and transmitting the V2X message to the processor 11; the processor 11 is configured to perform fusion processing on each V2X message, parse message content of the obtained fused V2X message, and determine a problem existing in the V2X network based on a parsing result.
Wherein each V2X receiver 10 is electrically connected to the processor 11. Optionally, the communication connection between each V2X receiver 10 and the processor 11 includes: the communication connection is realized through a Universal Serial Bus (USB) or through a Serial port. Optionally, the V2X receiver 10 may support an LTE-V2X protocol, and may also support a Dedicated Short Range Communications (DSRC) protocol, which may be set according to actual requirements. The processor 11 may be a system-on-chip, or other type of processing chip, etc.
In a V2X network, communication can be performed between V2X devices (such as vehicle-mounted terminals and road-side terminals), and the operation of a vehicle is assisted based on V2X information of communication interaction. In order to know the working state of each V2X device and whether the V2X message broadcast by each V2X device meets the requirement, the V2X message in the air interface can be collected in real time through a V2X message collecting device. Specifically, a plurality of V2X receivers 10 in the V2X message collection device jointly receive the V2X messages broadcast in the communication range thereof in real time, and transmit the received V2X messages to the processor 11 through the USB or serial port. The processor 11 performs fusion and aggregation on the received multiple paths of V2X messages, and performs real-time analysis on the message content of the obtained fusion V2X message to obtain specific information carried in the V2X message. Optionally, the parsed V2X message may be screened or queried according to the type of V2X message and/or the category of V2X device broadcasting the V2X message.
For example, the Message type of the V2X Message may be a Basic Safety Message (BSM), Road Side Information (RSI), Road Side Safety Message (RSM), traffic light phase and timing Message (SPAT), MAP Message (MAP), and the like. The BSM is generally broadcasted by the vehicle-mounted terminal, and can carry the speed, steering, braking, double flashing, position, etc. of the vehicle. The RSI is generally broadcast by roadside terminals, and is mostly used in a V2I scene, i.e., road construction, speed limit signs, overspeed warning, bus lane warning, and the like. The RSM is also applied in the V2I scenario, and is mainly used for identifying events such as vehicle accidents, vehicle anomalies, and foreign object intrusions by interfacing with roadside devices. The SPAT is also applied in the V2I scenario, for vehicle speed guidance, green wave push scenario, and the like. The MAP message is generally broadcast by a roadside terminal, and the roadside terminal transmits MAP information of a local area to a vehicle by broadcasting the MAP message, wherein the MAP information comprises local area intersection information, road section information, lane information, connection relation between roads and the like.
After obtaining the parsing result of the fused V2X message, the processor 11 may analyze whether the V2X message meets the preset requirement based on the parsing result, and further determine whether the working state of the road-side terminal or the vehicle-mounted terminal broadcasting the V2X message or other V2X devices participating in V2X communication is normal, and find other problems in the V2X network, so as to instruct operation and maintenance personnel to maintain the abnormal V2X device.
In order to further analyze the V2X network, a target message or a target V2X device that needs to be observed with emphasis may be preset, the processor 11 may receive and analyze a plurality of V2X messages at the same receiving time, and after obtaining the analysis result of each V2X message, the processor 11 may focus on tracking and observing the key fields in the target message to determine whether the target message meets the requirement; or the tracking observation is performed on the messages broadcast by the target V2X equipment to determine whether the working state of the target V2X equipment is normal.
In practical applications, in order to ensure the security of V2X communication, V2X messages broadcast in the V2X network are all encrypted V2X messages, and for this case, referring to fig. 2, the V2X message collecting apparatus may further include a decryptor 12. The decryptor 12 is electrically connected with the processor 11, and a key required by the analysis of the fused V2X message is stored in the decryptor 12; and the decryptor 12 is used for decrypting the fused V2X message according to the key and transmitting the decrypted V2X message to the processor 11 so that the processor 11 can analyze the decrypted V2X message.
The decryption algorithm that can be implemented in the decryptor 12 includes international algorithm symmetric encryption (AES), asymmetric encryption (DES), public key algorithm (RSA), Elliptic Curve Cryptography (ECC), HASH Algorithm (HASH), national cipher algorithm SM2/3/4, random number, and the like. Decryptor 12 may be implemented by an Application Specific Integrated Circuit (ASIC) or a Field Programmable Gate Array (FPGA).
The decryptor 12 receives the fused V2X message transmitted by the processor 11 in a USB mode or a serial port mode, decrypts the fused V2X message by using a key stored in the decryptor and a preset decryption algorithm, and transmits the decrypted V2X message to the processor 11 again. At this point, processor 11 may parse the message content of the decrypted V2X message.
The V2X message acquisition device provided in the embodiment of the present application includes a plurality of V2X receivers and a processor, where each V2X receiver jointly receives a V2X message broadcast in a V2X network, and transmits the V2X message to the processor; the processor performs fusion processing on each V2X message, analyzes the message content of the fused V2X message, and determines problems existing in the V2X network based on the analysis result. That is to say, the V2X message collection device can analyze the collected V2X message in real time, so as to analyze the problem existing in the V2X network according to the analysis result, and compared with the conventional test instrument that only the radio frequency performance index of the V2X network can be known, the V2X message collection device provided in the embodiment of the present application can effectively and deeply analyze the V2X network, thereby improving the test effect of the V2X network. Meanwhile, the V2X message collection device is provided with a plurality of V2X receivers, and V2X messages in a V2X network are received through a plurality of V2X receivers, so that the reliability of V2X message collection is improved.
In one embodiment, optionally, the V2X message collection device may further include a display device 13 for performing information interaction with an external object, and the display device 13 is electrically connected to the processor 11. Optionally, the display device includes a display screen and a touch screen. The touch screen may be a Liquid Crystal Display (LCD) touch screen. In this way, after obtaining the parsing result of the fused V2X message, the processor 11 may also visually present the parsing result. The display mode can be at least one of characters, voice or graphics.
Optionally, the V2X message collection device may also support recording and playback of test procedures. For this reason, on the basis of the above embodiment, optionally, with continuing reference to fig. 2, the V2X message collection device may further include: a memory 14; the memory 14 is electrically connected with the processor 11; the processor 11 is further configured to, when an event insertion instruction is monitored, set an event tag for a target fused V2X message according to the event insertion instruction, generate a test log file according to a fused V2X message with the event tag set therein and a fused V2X message without the event tag set therein in a test time period after the test is ended, and store the test log file in the memory 14; the event tag is used for playing back the test log file; the memory 14 is used to store test log files.
Specifically, the Memory 14 may be an Embedded Multi Media Card (eMMC) or a Dynamic Random Access Memory (DRAM), and of course, may also be other types of memories, which is not limited in this embodiment. As an optional implementation manner, the V2X message collecting device may support recording of a test process, and specifically, the processor 11 may correspondingly store the received fused V2X message in the memory 14 according to the receiving time, generate a test log file according to the fused V2X message corresponding to each receiving time within the specified time period after the test is completed, and store the test log file in the memory 14, so as to export the test log file when the user needs the test log file. Here, the user as used herein and hereinafter refers to a tester of the V2X network.
As another alternative, the V2X message collection device may also support the insertion of event tags during the recording process. Optionally, the event label may be any graphical label. The above-mentioned target fused V2X message refers to a fused V2X message that satisfies the event tag insertion condition. After obtaining the parsing result of the fused V2X message, processor 11 triggers the event insertion instruction when determining that the target field in the fused V2X message satisfies the preset condition based on the parsing result. At this time, the fused V2X message is the target fused V2X message, and the processor 11 can automatically set an event tag for the target fused V2X message according to the event inserting command. Of course, the user may also manually trigger the event insertion instruction according to the test requirement, at this time, the processor 11 obtains the event insertion instruction actively triggered by the user, and sets an event tag for the target fusion V2X message according to the event insertion instruction. After the test is finished, the processor 11 may generate a test log file according to the reception time of each of the fused V2X messages according to the fused V2X message in which the event tag is set and the fused V2X message in which the event tag is not set during the test period, and store the test log file in the memory 14.
Optionally, the processor 11 may also play back the test log file after the test is finished. In the process of playing back the test log file, the processor 11 may play back the test log file according to a play instruction of the user. Wherein the playing instruction is used for playing the fused V2X message of the target time. For example, in a specific implementation, a corresponding selection control may be set in the playback interface, and the user sets the target playback time through the selection control, at this time, the processor 11 may directly play back the fusion V2X message corresponding to the target playback time in the test log file according to the trigger operation of the user on the selection space, so as to quickly locate the key test time focused by the user, and improve the intelligence of human-computer interaction.
Optionally, during the process of playing back the test log file, the processor 11 may also monitor the trigger operation of the user on the event tag, and play back the test log file according to the trigger operation of the user on the event tag. Therefore, the processor 11 can directly play back the fused V2X message corresponding to the event label in the test log file, so as to quickly locate the key test time concerned by the user, and improve the intelligence of human-computer interaction.
Further, optionally, the processor 11 is further configured to analyze the test log file to generate an analysis report, and output the analysis report; the analysis report includes at least one of a V2X network coverage report, a thermal profile, and a V2X network quality report.
The processor 11 may analyze the category, the number, the reception strength, and the like of the fused V2X message at each reception time in the test process from the dimensional considerations of space, time, and the like, and automatically generate a V2X network coverage report, a thermodynamic distribution map, a V2X network quality report, and the like.
In the V2X message collection device provided in this embodiment, since the V2X message collection device is provided with a memory, the processor can perform associative storage on the received fused V2X message according to the receiving time, and set an event tag to the target fused V2X message in the storage process; and after the test is finished, generating a test log file according to the fused V2X message at each receiving time stored in the memory, playing back the test log file, and automatically generating an analysis report based on the test log file. That is to say, the V2X message collection device provides more test functions, which further improves the test effect of the V2X network.
In one embodiment, optionally, as shown in fig. 3, the V2X message collection device may further include a networking circuit 15 and a positioning circuit 16; the networking circuit 15 and the positioning circuit 16 are electrically connected to the processor 11, respectively; the networking circuit 15 is used for downloading map information required by the V2X network test or performing system upgrade on the V2X message acquisition equipment; and the positioning circuit 16 is used for positioning the V2X message acquisition equipment.
Specifically, the networking circuit 15 may be a second/third/fourth/fifth generation cellular communication module, a bluetooth module, or a Wireless-Fidelity (WIFI) module, etc. The Positioning circuit 16 may be a Global Positioning System (GPS), a Global Navigation Satellite System (GNSS), a beidou System, or the like.
In an application scenario, in the process of visually displaying the analysis result of the fused V2X message, the processor 11 may obtain the current location information of the V2X message acquisition device through the positioning circuit 16, and simultaneously download the map information around the location of the V2X message acquisition device through the networking circuit 15.
