[0039] Figure 2 Fig. 1 is a structural schematic diagram of a vehicle data conversion device provided by an embodiment of the present application. DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present application will be clearly and completely described in connection with the drawings of the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0041] Embodiment one

[0042] Please refer to Figure 1 A vehicle data conversion method provided by an embodiment of the present application includes the following steps S101-S104:

[0043] Step S101: in response to receiving a vehicle document data import instruction, obtaining a path of a vehicle document to be imported according to the vehicle document data import instruction.

[0044] In the embodiment, the vehicle data conversion method is mainly applied to a vehicle data integrated collection system. It can be understood that the vehicle data integrated collection system is used for collecting vehicle control network and Ethernet information network, and has core functions such as collection and fusion of all state data of the vehicle, preprocessing, data analysis, centralized recording, and unified transmission.

[0045] As a preferred solution, in response to receiving a vehicle document data import instruction, the path of the vehicle document to be imported is obtained according to the vehicle document data import instruction, specifically:

[0046] In response to receiving a vehicle document data import instruction sent by a vehicle control system, all data collected in a preset time period is marked according to the current local time; all transmission links are detected for busy, and an idle transmission link is obtained as the path of the vehicle document to be imported.

[0047] In the embodiment, the vehicle document data import instruction sent by the vehicle control system can enable the vehicle data integrated collection system to respond quickly and efficiently, and through acquisition of the local time, all data in the preset time period is marked, which is convenient for determining the data information of the time interval to be imported to the vehicle control system, avoiding that the imported data information is too large to affect the efficiency of data transmission and occupy too much system computing power.

[0048] As a preferred solution, the busy detection is performed on all transmission links according to the vehicle document data import instruction, and idle transmission links are obtained, specifically as follows:

[0049] According to the vehicle document data import instruction, the current data transmission flow value of all transmission links is obtained; when the current data transmission flow value of the transmission link is greater than a first preset value, the transmission link is marked as a busy transmission link; when the current data transmission flow value of the transmission link is not greater than the first preset value and is greater than a second preset value, whether the data transmitted by the transmission link and the data type thereof are at an important level is determined according to a preset transmission importance database; if yes, the transmission link is marked as a busy transmission link; if no, the transmission link is marked as a transmissible link; wherein the transmission importance database stores a plurality of data types and corresponding important levels thereof, the important levels include a primary processing level and a temporary processing level; when the current data transmission flow value of the transmission link is not greater than the second preset value, the transmission link is marked as a transmissible link; the transmission tasks of all transmissible links are suspended, and the transmissible links that are successfully suspended are marked as idle transmission links.

[0050] In the embodiment, the busy detection is performed on all transmission links according to the vehicle document data import instruction, and the busy state of the transmission link is determined through the flow value of all transmission links. Then, the transmission link whose current data transmission flow value is not greater than the first preset value and is greater than the second preset value is taken as a transmissible link, and it is further determined that the data transmitted in the transmission link is at the primary processing level or the temporary processing level, so that the data information with small data volume but high data importance level is avoided to be interrupted in the transmission link, and the vehicle is prevented from being unable to normally operate due to the lack of important operation data.

[0051] Further, the transmission link whose current data transmission flow value is not greater than the second preset value is also taken as a transmissible link, and the transmission tasks of all transmissible links are suspended, and the transmissible links that are successfully suspended are marked as idle transmission links. Preferably, when the transmission link whose current data transmission flow value is not greater than the second preset value is taken as a transmissible link, the transmission importance database is further used to screen the transmissible link that can be suspended.

[0052] It should be noted that the data information and data importance of different types of vehicles are different, and therefore the specific sizes of the first preset value and the second preset value can be set according to actual needs. In addition, the plurality of data types and corresponding important levels stored in the transmission importance database can also be set according to actual needs, vehicle types, purposes and conditions.

[0053] Step S102: obtaining the vehicle document through the path of the vehicle document to be imported, and analyzing the vehicle document, so that in the unpacking process of the vehicle document, vehicle operation data is directly obtained from the vehicle document according to the XML protocol.

[0054] As a preferred solution, the obtaining the vehicle document through the path of the vehicle document to be imported, and analyzing the vehicle document, so that in the unpacking process of the vehicle document, vehicle operation data is directly obtained from the vehicle document according to the XML protocol, specifically comprises:

[0055] The vehicle document is obtained through the path of the vehicle document to be imported, and the vehicle document is analyzed to identify the format type of the vehicle document; according to the format type of the vehicle document, a corresponding analysis program is called to analyze the vehicle document, so that in the unpacking process of the vehicle document, libxml and boost spirit x3 are called to directly obtain vehicle operation data corresponding to the definition signal from the vehicle document according to the definition signal in the XML protocol; wherein the definition signal is set by the vehicle document data import instruction.

[0056] In this embodiment, the corresponding vehicle document can be quickly and accurately obtained through the path of the vehicle document to be imported, so that the format type of the corresponding vehicle document is identified by analyzing the vehicle document, so that the corresponding analysis program can be called according to the format type of the vehicle document, so as to realize different vehicle document analysis for different format types.

[0057] In this embodiment, the xml protocol is used, and the xml protocol converted from dbc / excel is compatible. In terms of data analysis, libxml and boost spirit x3 are used to quickly import data analysis: in real-time frame packing and unpacking, the corresponding structure body does not need to be declared in advance, and according to the definition signal in the xml protocol and the received vehicle document data or the data to be packed, the corresponding vehicle operation data is directly obtained or set.

[0058] It should be noted that libxml is a library for parsing xml files, and boost spirit x3 is a data parser of an interface program. In terms of data analysis, libxml and boost spirit x3 are used to quickly import the data analysis program, thereby improving the analysis speed.

[0059] Step S103: constructing real-time frame packing according to the directly obtained vehicle operation data, so as to obtain vehicle operation data and its annotation data.

[0060] As a preferred solution, the vehicle operation values include real-time position of the vehicle, driving track, engine start and stop time, engine temperature, engine speed, throttle opening, idling time length, engine continuous working hours, battery voltage, whether the air conditioner is on, gear information of the transmission, shift pattern of the transmission and driving speed of the vehicle; and the annotation data is a description of the vehicle operation data.

[0061] In the embodiment, the vehicle operation values mainly include state operation data related to the operation process of the vehicle. With the development of intelligent vehicles, the vehicle operation data is not limited to the data generated during the driving process of the vehicle, but also includes intelligent driving, road information data, positioning information data, lane recognition data and other information.

[0062] As a preferred solution, the vehicle operation values and the annotation data thereof are obtained by constructing a real-time frame group package according to the directly obtained vehicle operation data, specifically as follows:

[0063] The directly obtained vehicle operation data is constructed into a real-time frame through an XML protocol; each real-time frame is packaged by adding corresponding annotation information of the real-time frame, so as to obtain a real-time frame group package; wherein the real-time frame group package includes the vehicle operation values and the annotation data thereof.

[0064] In the embodiment, the vehicle operation data is directly obtained through an XML protocol without declaring a corresponding structure body in advance, and a real-time data frame is constructed by using the obtained vehicle operation data, so that multiple data frames can be bundled together and a header information is added to the data frames for packaging. In the embodiment, the corresponding annotation information is added as the header information of the package. In addition, the packaging can enable multiple frames of data to be sent at the same time, thereby improving the efficiency of communication. Furthermore, the frame package of data can improve the reliability of data transmission.

[0065] Step S104: The vehicle operation values and the annotation data thereof are imported into a vehicle control system, so that the vehicle control system directly processes corresponding vehicle operation values according to the annotation data, thereby completing the conversion of vehicle data.

[0066] As a preferred solution, the vehicle operation values and the annotation data thereof are imported into a vehicle control system, so that the vehicle control system directly processes corresponding vehicle operation values according to the annotation data, specifically as follows:

[0067] The vehicle operation value and its comment data are imported into the vehicle control system in the form of real-time frame group packets, so that the vehicle control system directly reads real-time frames according to the comment data, calls corresponding analysis programs for analysis processing to obtain corresponding structures and type attributes, constructs a table corresponding to each structure, fills the vehicle operation value in each real-time frame into the constructed table, and thus completes the processing of the vehicle operation value.

[0068] It should be noted that the traditional can transmission uses a DBC file, which has strong relevance but is inconvenient to edit, slow to analyze, and difficult to expand. In addition, the Ethernet uses an excel communication matrix, which is easy to expand but has a non-uniform format and is difficult to be reused by multiple systems or even the host computer and the lower computer of the same system. In the embodiment, the xml protocol is used, and the xml protocol converted from the DBC / excel is compatible. When the real-time frame is packaged and unpacked, the corresponding structure can be directly obtained / set according to the signals defined in the xml protocol and the received data or the data to be packaged, without the need for prior declaration of the corresponding structure. Moreover, the embodiment can be directly reused by the host computer and the lower computer (reusable), and for subsequent changes of the communication matrix, the xml protocol content can be directly modified, which is easy to expand. The modified xml protocol content is mainly the defined signals in the XML protocol, which can also be modified and set by the vehicle document data import instruction, so that the modification of the code is not required.

[0069] The above embodiment has the following effects:

[0070] The technical solution of the present application obtains the path of the imported vehicle document in response to the vehicle document data import instruction, and then obtains the vehicle document, so as to analyze the vehicle document. In the unpacking process of the vehicle document, the corresponding structure can be directly obtained from the vehicle document according to the XML protocol, without the need for prior declaration of the corresponding structure, thereby improving the efficiency of data analysis and conversion. Moreover, the construction of the real-time frame group can be realized according to the directly obtained vehicle operation data, so as to import the vehicle operation value and its comment data into the vehicle control system, which can ensure that the obtained vehicle operation value is compatible with multiple systems, realizes the reuse of the host computer and the lower computer of the vehicle, and further improves the data import and export efficiency.
