And step S20, carrying out binary conversion on the CAN data and the LOG data.
It should be understood that the representation format of CAN data is binary, and the representation format of LOG data is hexadecimal, and as the name suggests, data in different representation formats cannot be compared, so that the CAN data and the LOG data are subjected to binary conversion to make the representation formats of the CAN data and the LOG data identical, and because the LOG data transmitted to the TBOX server by the vehicle-mounted TBOX is hexadecimal, the CAN data CAN be converted from binary to hexadecimal to improve the efficiency of concurrently comparing the CAN data and the LOG data.

step S101, a detection instruction of a target vehicle is obtained, a corresponding data feedback instruction is generated according to the detection instruction, and the data feedback instruction is sent to each component of the target vehicle, so that each component feeds back corresponding CAN data according to the data feedback instruction.
It should be understood that, after receiving the detection instruction, the vehicle-mounted TBOX sends the data feedback instruction to each component so that each component feeds back corresponding CAN data to the vehicle-mounted TBOX based on the data feedback instruction, for example, each component is an engine, a door, a tire, a lamp, and the like, and the CAN data received by the vehicle-mounted TBOX is corresponding CAN data of the engine, the door, the tire, and the lamp.
It can be understood that the detection instruction refers to an instruction triggered when the vehicle-mounted TBOX changes according to its version or function, the detection instruction includes a version upgrade detection instruction, a function update detection instruction and an alarm information detection instruction, the version upgrade detection instruction refers to a detection instruction generated when software of the vehicle-mounted TBOX is upgraded, for example, the current software version is 12.1, the upgraded software version is 12.5, the function update detection instruction refers to a detection instruction generated when the number of functions of the vehicle-mounted TBOX increases, the alarm information refers to a detection instruction generated when alarm information sent by any component in a target vehicle is received, the version upgrade detection instruction, the function update detection instruction, the alarm information detection instruction and the user detection instruction can all trigger a self-check of the whole data transmission link, and the data feedback instruction refers to an instruction for feeding back data by each component of a user and a target server.
And S102, sending the data feedback instruction to a target server so that the target server feeds back LOG data according to the data feedback instruction and a preset serial port.
It can be understood that the target server refers to a server loaded with data access, data processing and data pushing of the vehicle-mounted TBOX, that is, the target server is a TBOX server, and after receiving the detection instruction, generates a data feedback instruction according to the detection instruction, and the vehicle-mounted TBOX sends the data feedback instruction to the target server, so that the target server feeds back LOG data through a preset serial port according to the received LOG data sent by the vehicle-mounted TBOX, where the preset serial port refers to a serial interface of the vehicle-mounted TBOX, and the target server transmits the LOG data to the vehicle-mounted TBOX through the preset serial port.
And step S103, receiving CAN data fed back by each part and LOG data sent by the target server in real time.
It should be understood that the vehicle-mounted TBOX acquires the CAN data fed back by each component and the LOG data sent by the target server in a real-time receiving manner to prevent data omission and loss, and after the receiving is completed, the CAN data and the LOG data of the target vehicle at the current moment are obtained.
In the embodiment, a detection instruction of a target vehicle is obtained, a corresponding data feedback instruction is generated according to the detection instruction, and the data feedback instruction is sent to each component of the target vehicle, so that each component feeds back corresponding CAN data according to the data feedback instruction; sending the data feedback instruction to a target server so that the target server feeds back LOG data according to the data feedback instruction and a preset serial port; receiving CAN data fed back by each component and LOG data sent by the target server in real time; according to the embodiment, the data feedback instructions are respectively sent to the corresponding components and the target server, so that the components feed back the corresponding CAN data according to the data feedback instructions, and the target server feeds back the LOG data through the preset serial port according to the data feedback instructions, and receives the CAN data fed back by the components and the LOG data sent by the target server in real time, and therefore accuracy of obtaining the CAN data and the LOG data is effectively improved.
In an embodiment, as shown in fig. 4, a third embodiment of the method for detecting a data transmission link according to the present invention is proposed based on the first embodiment, where the step S30 includes:
step S301, it is determined whether ASCII code exists in the CAN data and LOG data after the binary conversion.
It is understood that ASCII encoding is to represent upper and lower case letters, numerals 0 to 9, punctuation marks, and special control characters used in american english by using a 7-bit binary number (the remaining 1-bit binary is 0), and after the CAN data and LOG data are binary-converted, it is determined whether ASCII encoding exists in the converted CAN data and LOG data.
Further, after step S301, the method further includes: if the CAN data and the LOG data after the binary conversion do not have ASCII codes, judging whether the CAN data and the LOG data after the binary conversion are non-constant values or not; if the CAN data and the LOG data after the binary conversion are not constant values, judging whether the difference values between the CAN data and the LOG data after the binary conversion and a preset relational database are within a preset range or not; and if the difference value is within the preset range, displaying the concurrent comparison result through a preset display strategy.
It should be understood that when ASCII code does not exist in the binary-converted CAN data and LOG data, it is necessary to continuously determine whether the binary-converted CAN data and LOG data are non-constant values, where a non-constant value means that the data are variable, and when the binary-converted CAN data and LOG data are non-constant values, it is determined whether a difference between the binary-converted CAN data and LOG data and the CAN data and the LOG data in the preset relationship database is within a preset range, and if so, yellow is directly displayed.
Further, after determining whether the CAN data and the LOG data after the binary conversion are non-constant values, the method further includes: if the CAN data and the LOG data after the binary conversion are constant values and the concurrent comparison result is inconsistent, extracting keywords of the LOG data according to a target signal transmission development protocol; generating corresponding fault signal early warning information according to the keywords; and sending the fault signal early warning information to a TBOX background server so that the TBOX background server records the fault signal early warning information.
It CAN be understood that when the CAN data and the LOG data after the binary conversion are confirmed to be constant values and are inconsistent with the CAN data and the LOG data in the preset relational database, keywords of the LOG data are extracted through a target signal transmission development protocol, a subsequent and next iccid number of the LOG data is output through the keywords, a specific fault component CAN be confirmed through the iccid number, and corresponding fault signal early warning information is obtained according to the iccid number.
It should be noted that the target signal transmission development protocol is composed of LOG printing items, LOG printing switches, LOG printing rules, LOG information requests, and LOG printing grades, and since different developers, different engineers, and different writing rules are different, keywords of LOG data cannot be accurately extracted, so that unified development is performed according to the target signal transmission development protocol, accuracy of extracting keywords of LOG data can be effectively improved, and automatic detection of a data transmission link of a target vehicle is realized.
It can be understood that the LOG printing item refers to a specified printed content, such as a 4G software version of TBOX, a sleep state, and the like, the LOG printing switch refers to a switch responsible for turning on or off the LOG printing item, specifically, sending a corresponding instruction through a preset serial port to drive the turning on or off of the switch, and the LOG printing rule refers to an output rule of the LOG printing item, specifically, first, each LOG data is preceded by a LOG retention keyword, that is, a LOG message header, for example, DFL _ TCU _ TEST; secondly, each LOG output content is fixed with a key and cannot be changed freely, for example, iccid of TBOX is output as a key, a LOG information request refers to outputting corresponding LOG information such as TBOX self-inspection information when a detection instruction is received, and a LOG printing level refers to setting a corresponding printing level according to LOG printing content, that is, information outside a detection range has a lower priority, thereby improving the accuracy of outputting LOG data.
Further, after determining whether the CAN data and the LOG data after the binary conversion are non-constant values, the method further includes: and if the CAN data and the LOG data after the binary conversion are constant values, carrying out concurrent comparison on the CAN data and the LOG data after the binary conversion according to a preset relational database.
It should be understood that, when the CAN data and the LOG data after the binary conversion are fixed values, the CAN data and the LOG data after the code conversion are subjected to concurrent comparison through the preset relational database, whether the CAN data and the LOG data after the code conversion are consistent with the CAN data and the LOG data in the preset relational database is judged, and if the CAN data and the LOG data after the code conversion are consistent with the CAN data and the LOG data in the preset relational database, the concurrent comparison result is displayed in white through a preset display strategy.
In step S302, if ASCII code exists in the CAN data and LOG data after the binary conversion, code conversion is performed on the CAN data and LOG data after the binary conversion.
It should be understood that if ASCII code exists in the CAN data and LOG data after the binary conversion, the CAN data and LOG data with ASCII code need to be code-converted, and the specific code conversion rule is as follows: false =0,true =1.
And step S303, carrying out concurrent comparison on the CAN data and the LOG data after code conversion according to a preset relational database.
It CAN be understood that after the CAN data and the LOG data after code conversion are obtained, the CAN data and the LOG data after code conversion need to be subjected to concurrent comparison through a preset relational database to judge whether the CAN data and the LOG data after code conversion are consistent with the CAN data and the LOG data in the preset relational database, and if the CAN data and the LOG data after code conversion are consistent with the CAN data and the LOG data in the preset relational database, a concurrent comparison result is displayed in green through a preset display strategy.
Further, before step S303, the method further includes: acquiring identification information of a target vehicle; setting target CAN data and target LOG data according to the identification information; carrying out data fusion on the target CAN data and the target LOG data; and establishing a preset relational database according to the data fusion result.
It should be understood that the identification information refers to information capable of uniquely identifying the target vehicle, for example, an engine number of the target vehicle, after the identification information of the target vehicle is obtained, the target CAN data and the target LOG data are set through the identification information, the target CAN data and the target LOG data are processed through a data fusion technology, that is, a corresponding relationship between the target CAN data and the target LOG data is established, and the relationship is written into a program database, that is, a preset relationship database is obtained.
In the embodiment, whether the ASCII code exists in the CAN data and LOG data after the binary conversion is judged; if ASCII codes exist in the CAN data and the LOG data after the binary conversion, performing code conversion on the CAN data and the LOG data after the binary conversion; according to a preset relational database, performing concurrent comparison on the CAN data and the LOG data after code conversion; in the embodiment, the CAN data and the LOG data after code conversion are subjected to concurrent comparison through the preset relational database, so that the accuracy of efficiently detecting the CAN data and the LOG data CAN be realized.
