[0058] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0059] The data mapping method, device, electronic device, and storage medium according to the embodiments of the present disclosure are described below with reference to the accompanying drawings.

[0060] Figure 1 A flowchart of a data mapping method provided by an embodiment of the present disclosure is provided.

[0061] like Figure 1 As shown, the method comprises the following steps:

[0062] Step 101, obtaining a first information table and a second information table; wherein the first information table records the port information of each electronic system and the target signal information received by each port, and the second information table records the signal information transmitted by the vehicle bus.

[0063] The port information table refers to a table that records the information of each port in a computer or network device. In one possible implementation of the embodiment of the present application, the port information table can be obtained by parsing the AUTOSAR standard file through a preset file parser; the port information table includes information such as the name, port direction, and data type of each port.

[0064] Step 102: Compare the target signal information corresponding to each port information in the first information table with the signal information in the second information table to see whether they are consistent, and obtain a comparison result.

[0065] In one possible implementation of the present application, the consistency of port information and signal information means that their names, IDs, lengths, data types and other information are completely consistent. If a port information is consistent with a signal information, then it can be determined that they have a data mapping relationship. It should be noted that this narrative method is only an exemplary description and is not a specific limitation on the specific information content. The present application embodiment does not limit the specific information content. By determining the data mapping relationship between port information and signal information, the data flow and communication process in the CAN bus system can be better understood.

[0066] Step 103: If the comparison result indicates that the second information table contains signal information consistent with the target signal information, it is determined that the port information and signal information having a consistent relationship have a data mapping relationship.

[0067] Signal information will be connected to the corresponding ports through data mapping to achieve data transmission and exchange; the determination of the mapping relationship can help developers configure and connect data flows between different components more quickly, simplify the development process, and improve development efficiency.

[0068] Step 104: Record the port information and the signal information having a mapping relationship in a mapping relationship table.

[0069] The mapping relationship table is used to record the mapping relationship between each port information and signal information. By generating a mapping relationship table, you can better understand the relationship between each port and signal, so as to better design, debug and optimize the system. At the same time, the mapping relationship table can also be used as part of the system documentation to facilitate subsequent maintenance and management.

[0070] The data mapping method provided by the present disclosure has a main technical solution including: first, obtaining a first information table and a second information table; wherein the first information table records the port information of each electronic system and the target signal information received by each port, and the second information table records the signal information transmitted by the vehicle bus; secondly, comparing whether the target signal information corresponding to each port information in the first information table is consistent with the signal information in the second information table, and obtaining a comparison result; if the comparison result indicates that the second information table contains signal information consistent with the target signal information, then it is determined that the port information and signal information with a consistent relationship have a data mapping relationship; finally, the port information and signal information with a mapping relationship are recorded in a mapping relationship table. Compared with the related art, the embodiment of the present application improves development efficiency by automatically determining whether there is a data mapping relationship between the first information and the second information, and establishing a data mapping relationship between the two information with a mapping relationship, avoiding the problem of manual connection errors, and being able to quickly and accurately establish a data mapping relationship, making data processing more efficient and reliable.

[0071] In one possible implementation of the embodiment of the present application, when executing step 102, it is necessary to compare each port information with each signal information one by one; see Figure 2 , Figure 2 A flow chart of a data mapping method provided in an embodiment of the present disclosure includes:

[0072] Step 201: Use one of the port information in the first information table as target port information.

[0073] In an implementable manner of the embodiment of the present application, when determining the target port information, there are the following two methods: First, determine in sequence according to the arrangement order of the port information in the first information table; Second, randomly determine the target port information in the first information table, and delete the determined target port information from the first information list to prevent duplicate port information from being determined during subsequent random determination; The embodiment of the present application takes the first determination method (sequential determination) as an example for illustration. However, it should be noted that this narrative method is only an exemplary illustration and is not a specific limitation on the specific determination method. The embodiment of the present application does not limit the determination method.

[0074] Step 202: Compare whether the target signal information corresponding to the target port information is the same as each of the signal information in the second information table to determine whether there is target signal information with a data mapping relationship.

[0075] In an implementable manner of the embodiment of the present application, the port information includes: port name, port direction, port data type, and the signal information includes: signal name, signal direction, signal data type.

[0076] In an implementable manner of the embodiment of the present application, since there may be the same signals in different information in the second information table, to ensure uniqueness during matching, the signal name can be composed of <DBC_Signal_Name>_<DBC_Message_Name>_<DBC_Network_Name> (<DBC signal name>_<DBC message name>_<DBC network name>) for distinguishing different signal information; It should be noted that this naming method is only an exemplary illustration and is not a limitation on the specific naming method.

[0077] When performing step 202, the following sub-steps can be referred to:

[0078] Take one of the signal information in the second information table as the target signal information; In an implementable manner of the embodiment of the present application, when determining the target signal information, the following two methods can be used: First, determine the target signal information according to the arrangement order of each signal information in the second information table; Second, randomly determine the target signal information; Specifically, the embodiment of the present application does not limit the determination method.

[0079] When determining whether the target signal information and the target port information have a data mapping relationship, the following three aspects also need to be considered:

[0080] Determine whether the signal name of the target signal information is the same as the port information of the target port information, and

[0081] determining whether the signal direction of the target signal information is the same as the port direction of the target port information, and

[0082] It is determined whether the signal data type of the target signal information is the same as the port data type of the target port information.

[0083] In one possible implementation of the embodiment of the present application, when determining whether the target signal information and the target port information have a data mapping relationship, it is necessary to comprehensively consider factors such as the signal name, signal direction, and signal data type to ensure the correctness and accuracy of data transmission. It should be noted that this narrative method is not a limitation on the specific comparison order, and the embodiment of the present application does not limit the comparison order.

[0084] When the signal name is the same as the port information, the signal direction is the same as the port direction, and the signal data type is the same as the port data type, it is determined that a mapping relationship exists between the target port information and the target signal information.

[0085] In the case where the signal name, signal direction, signal data type, etc. are the same, it can be determined that there is a data mapping relationship between the target signal information and the target port information.

[0086] Step 203: If it exists, save the target port information and the target signal information.

[0087] After determining that there is a data mapping relationship between the target signal information and the target port information, they need to be saved and sorted according to the arrangement order of the port information. This can facilitate subsequent data processing and analysis. Specifically, the target port information and the target signal information can be saved in a data structure, such as an array or a dictionary. When saving, the port information can be used as the key and the signal information as the value, which can be easily searched and accessed.

[0088] Step 204: After excluding the target port information from the first information table, return to the step of using one of the port information in the first information table as the target port information until all the port information in the first information table is traversed.

[0089] After the data mapping relationship is determined, the target port information is re-determined in the first information table, the target signal information is determined in the second information table, and the determination of the data mapping relationship is continued until all the port information is determined.

[0090] When determining whether there is a data mapping relationship between the target signal information and the target port information, if not, it is necessary to continue to determine the data mapping relationship according to the arrangement order of the port information until all the port information in the first information table is determined. Specifically, each port information in the first information table can be traversed to determine whether there is a target signal information that matches it. If it does, the target port information and the target signal information are saved, and the matching of the next port information is continued. If it does not exist, the next target signal information is continued to be matched until the matching signal information is found or all the signal information is traversed. After determining that all the port information is completed, the determination of the data mapping relationship can be ended, and the result can be saved in a data structure, such as a two-dimensional array or a matrix. This can facilitate subsequent data processing and analysis, such as data visualization or data mining operations.

[0091] When determining whether there is a data mapping relationship between the target signal information and the target port information, it is necessary to perform one-to-one matching according to the arrangement order of the port information to ensure the accuracy and reliability of data processing and analysis.

[0092] In one possible implementation of the embodiment of the present application, after obtaining the first information table and the second information table, the method further includes:

[0093] respectively determining whether the first information table and the second information table are empty;

[0094] In one possible implementation of the embodiment of the present application, there may be a situation where a file is lost, resulting in data loss in the first information table or the second information table. Specifically, it can be determined in the following manner:

[0095] 1. It can be judged by checking whether the number of rows and columns of the first information table is zero. If both the number of rows and the number of columns are zero, it can be considered that the first information table is empty.

[0096] 2. If the first information table is not empty, it is necessary to further check whether it contains valid port information and signal information. This can be determined by checking whether there are non-empty cells in the table.

[0097] 3. It can be judged by checking whether the number of rows and columns of the second information table is zero. If both the number of rows and the number of columns are zero, it can be considered that the second information table is empty.

[0098] 4. If the second information table is not empty, it is necessary to further check whether it contains valid port information and signal information. This can be determined by checking whether there are non-empty cells in the table.

[0099] When both the first information table and the second information table are not empty, it is determined whether the port information and the signal information in the first information table and the second information table have a data mapping relationship according to whether the port information in the first information table is consistent with the signal information in the second information table. Please refer to steps 201 to 204 for the specific implementation process, which will not be described one by one in the embodiment of the present application.

[0100] In one implementable method of the embodiment of the present application, the mapping relationship table finally output may be an empty list, and there are the following two situations: first, when at least one list in the first information table or the second information table is empty, an empty list will be output when the mapping relationship table is output; second, when all the port information in the first information table has no corresponding signal information with a mapping relationship in the second information table, an empty list will be output when the mapping relationship table is output.

[0101] In an implementable manner of an embodiment of the present application, after determining the data mapping relationship between the port information and the signal information, the method further includes: converting the target data mapping table into a target code in the preset template format according to a preset template format. In an implementable manner of an embodiment of the present application, an RTE code that complies with the AUTOSAR interface standard is generated. According to the Data Mapping list obtained by automatic Data Mapping, each member in the list is a pair of DataMappings, including information such as Signal Name, Direction, Data Type, SWC Name, Port Name, etc. The RTE code generation module converts the list into a format that complies with the Jinja2 code template. The final dynamic RTE code is obtained through the Jinja2 template engine.
