[0002] With the continuous improvement of digitalization level, the communication protocol is also continuously evolving.

[0022] Embodiments of this application will now be described in more detail with reference to the accompanying drawings. While some embodiments of this application are shown in the drawings, it should be understood that this application can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this application. It should be understood that the drawings and embodiments of this application are for illustrative purposes only and are not intended to limit the scope of protection of this application.

[0023] It should be understood that the steps described in the method embodiments of this application may be performed in different orders and / or in parallel. Furthermore, the method embodiments may include additional steps and / or omit the steps shown. The scope of this application is not limited in this respect.

[0024] The data conversion method, conversion device, electronic device, and storage medium provided in the embodiments of this application are described below with reference to the accompanying drawings.

[0025] refer to Figure 1 This is a flowchart of a data conversion method provided in an embodiment of this application.

[0026] Step S101: Obtain the first data structure of the first message; wherein the first data structure includes the data code length and the first signal attribute; In step S102, in response to determining that the data code length is not greater than the target threshold, the first message is mapped to the second message based on the first signal attribute; and in response to determining that the data code length is greater than the target threshold, the number of split frames of the first message is determined, and the first message is mapped to the second message based on the number of split frames and the first signal attribute.

[0027] Specifically, the first message is first acquired, analyzed to obtain and store the first data structure of the first message, wherein the first data structure includes a data code length and a first signal attribute. Further, the data code length in the first data structure is compared with a target threshold. If the data code length is not greater than the target threshold, the first message is mapped to a second message according to the first signal attribute. If the data code length is greater than the target threshold, the number of frames to be split in the first message is determined according to the data code length, and the first message is mapped to a second message based on the number of frames to be split and the first signal attribute.

[0028] In the embodiments of this application, the first message is preferably a DBC file of the CAN FD protocol; the second message is preferably a DBC file of the CAN protocol; and the target threshold is preferably 8 bits.

[0029] In addition to the corresponding first data structure, the first message also includes a unique ID, a name for identification, node information that sent the message, a data list containing all signals, a Boolean value indicating whether it is a second message, and a group identifier for associating split or merged messages.

[0030] This application obtains the data code length of the first message and maps it in different ways according to the data code length to obtain the second message. This enables the first message to be quickly converted into the second message according to rules. Since no manual intervention is required during the conversion, the conversion efficiency is effectively improved while avoiding errors caused by manual operation, ensuring the accuracy of message attributes, further guaranteeing the reliability of the second message data, and reducing the occurrence of system failures caused by errors in the converted content.

[0031] As an optional embodiment, the first signal attributes include the start bit, bit length, and byte order of each signal in the first message; mapping the first message to the second message based on the first signal attributes includes: mapping the first message to the second message in byte order, with the start bit as the offset reference and the bit length as the mapping size.

[0032] Specifically, the first signal attributes include the start bit, bit length, and byte order of each signal in the first message. In addition, the first signal attributes also include the signal name, data type, precision and offset for physical value conversion, physical unit, maximum and minimum values ​​of the value range, split identifier for marking the split status, and associated fields pointing to the original signal name for each signal. When mapping the first message to the second message, the other attribute information in the first signal attributes will also be mapped to the signal attribute information of the second message.

[0033] When the data code length of the first data structure is no greater than the target threshold, the starting bit position of the signal in the first message data field is used as the starting reference point for its positioning in the second message data field. This ensures that the relative position of the signal is maintained in the data, effectively and accurately locating the signal. Furthermore, during the mapping of the first message to the second message, the corresponding bit sequence is extracted from the original data of the first message strictly according to the bit length of the signal, and copied completely and without modification to the second message data field. This ensures that the binary content of the signal is not truncated or expanded, thus guaranteeing that the original numerical information it represents and the physical value calculated by precision and offset remain completely unchanged. Moreover, during the mapping process, the original byte order setting of the signal must be strictly followed, and the signal is laid out in the second message data field according to the same rules. This ensures that the signal value can be correctly parsed across different systems or devices, avoiding data distortion due to incorrect byte order.

[0034] As an optional embodiment, determining the number of frames to be split in the first message includes: in response to determining that the quotient of the data code length and the target threshold is an integer, using the quotient of the data code length and the target threshold as the number of frames to be split; in response to determining that the quotient of the data code length and the target threshold is not an integer, adding a preset value to the integer part of the quotient of the data code length and the target threshold and using it as the number of frames to be split.

[0035] Specifically, when the data code length of the first data structure is greater than the target threshold, it is necessary to calculate the quotient of the data code length of the first data structure and the target threshold to determine the number of frames to be split in the first message. When the quotient of the data code length and the target threshold is an integer, the quotient of the current data code length and the target threshold is directly determined as the number of frames to be split; when the quotient of the data code length and the target threshold is not an integer, the integer part of the quotient of the data code length and the target threshold is increased by a preset value and then used as the number of frames to be split, wherein the preset value of the increase is preferably 1. For example, if the data code length is 32 bytes and the target threshold is 8 bytes, then the quotient obtained by dividing 32 by 8 is 4, and 4 is an integer, so it can be directly used as the number of frames to be split; when the data code length is 18 bytes and the target threshold is 8 bytes, then the quotient obtained by dividing 18 by 8 is 2.25, and the integer part of the quotient 2 is increased by 1 to obtain the number of frames to be split as 3.

[0036] refer to Figure 2 This is a flowchart of a second message based on the number of split frames and the first signal attribute mapping provided in an embodiment of this application.

[0037] Step S201: Based on the number of split frames, map the valid data in the first message data field to the second message data field.

[0038] Specifically, based on the number of split frames, the valid data in the first message data field is mapped accordingly to obtain the second message data field. The valid data in the data field is the original data byte with specific physical meaning defined by the top number in the first message data field, excluding empty bytes or invalid data filled to meet the protocol length requirements.

[0039] refer to Figure 3 This is a flowchart illustrating how valid data in the first message data field is mapped to the second message data field, as provided in this application embodiment.

[0040] Step S301: Based on the number of split frames, split the valid data in the data field of the first message and obtain the split data; Step S302: Based on the preset padding value, pad the data in the split data whose length is less than the target threshold to obtain the padded data; Step S303: Map the padded data and the data in the split data whose length is not less than the target threshold to the second message data field.

[0041] Specifically, when mapping valid data in the first message data field to the second message data field, the valid data in the first message data first needs to be split based on the splitting radix. Taking a data code length of 18 bytes and a target threshold of 8 bytes as an example, the number of splitting frames is 3. Further, based on the number of splitting frames, the valid data in the first message data is split into 3 segments starting from the start bit: two segments of 8 bytes each and one segment of 2 bytes each.

[0042] For data segments in the split data whose length is less than the target threshold, a preset padding value is used. In this embodiment, the preset padding value is preferably a null byte (0x00). Taking the specific embodiment above as an example, data with a length of 2 bytes needs to be padded so that the length of this data reaches the target threshold, so that the length of the second message data field meets the communication requirements of the protocol described in the first message.

[0043] Furthermore, the padded data and the split data with a length not less than the target threshold are mapped to the second message data field to complete the precise division of physical data bits from large data length to small data length, laying the foundation for subsequent signal analysis.

[0044] Step S202: Based on the first signal attribute, assign a signal to each data item in the second message data field and generate the second message signal field.

[0045] Specifically, based on the first signal attribute, each data item in the second message data field is assigned a signal, and a second message signal field is generated, so as to fully adapt the signal definition of the first message to the signal structure of the second message.

[0046] refer to Figure 4 This is a flowchart of generating the second message signal field provided in an embodiment of this application.

[0047] Step S401: Based on the start bit and bit length, determine the start byte and end byte of several signals in the first message signal field respectively; Step S402: Separate the signals in which the start byte and the end byte are not equal from the signals to obtain the separated signals. Step S403: Based on byte order, the split signals and signals with equal start and end bytes are mapped to the second message signal field.

[0048] Specifically, the system acquires signals that need to cross a single target threshold length by calculating the start byte and end byte of each signal's start and end bits, thus determining whether a splitting operation is necessary. The calculation rules for the start and end bytes are as follows: for the start bit, the quotient obtained by dividing the start bit by the target threshold and taking the integer part is used as the start byte; for the end bit, the end bit is usually the start bit plus the signal bit length minus one, and the quotient obtained by dividing the end bit by the target threshold and taking the integer part is used as the end byte.

[0049] Taking a signal with a target threshold of 8 bytes, a signal start bit of 12, and a bit length of 16 as an example, the quotient of the start bit 12 divided by 8 is rounded down to 1. Calculate 12 plus 16 minus 1 to get the end bit of 27. Further divide 27 by 8 and round down to 3. At this point, we can see that the start byte is not equal to the end byte.

[0050] For signals where the start byte and end byte are not equal, the signal is split into several signals at the first byte boundary it crosses. Furthermore, during the splitting process, splitting markers are added to several signals. For example, the original signal "EngineSpeed" may be split into two sub-signals, "EngineSpeed_split0" and "EngineSpeed_split1".

[0051] Furthermore, the split signals and the signals that do not need to be split are uniformly mapped to obtain the information field of the second message, which is used to describe the physical meaning of each bit in the current second message data field and includes the second attribute information of all signals assigned to this second message.

[0052] During the mapping process, the original byte order of each signal must be strictly followed so that the signal field of the second message can match the data field of the second message. This ensures that the binary representation of the signal value can be correctly parsed in multi-byte systems and avoids data errors caused by byte order misunderstanding.

[0053] Step S203: Generate a second message based on the second message data field and the second message signal field.

[0054] Specifically, the second message data field that conforms to the corresponding communication protocol specification is integrated with the second message signal field that accurately describes the meaning of its data to obtain a complete second message.

[0055] It should be noted that during the generation of the second message, the ID of the second message also needs to be configured based on the ID information of the first message. The communication protocol corresponding to the second message has an extended frame format, which can use a 29-bit identifier to add extra encoded information to the second message. The highest 3 bits are selected from the 29-bit address of the identifier, starting from 0, to store the position of the current second message in the split sequence, that is, the frame number of the current second message. For example, if a first message can be split into 3 second messages, the frame numbers of the second messages are "000", "001" and "010", which are used to represent the 0th frame message, the 1st frame message and the 2nd frame message, respectively. Thus, the extended identifier of the second message is composed of "3-bit frame number + 26-bit basic ID of the first message".

[0056] refer to Figure 5 This is a flowchart of a method for generating a first message from a second message, provided in an embodiment of this application.

[0057] Step S501: Obtain the second data structure of the second message; wherein the second data structure includes a second signal attribute and an identifier.

[0058] Specifically, the second message is acquired, the second message is analyzed to obtain the second data structure, wherein the second data structure includes the second signal attribute and the identifier.

[0059] The second signal attributes include the complete definition of each signal in the second message, including but not limited to the signal name (which may include a split identifier), start bit, bit length, byte order, data type, precision, offset, etc.; the identifier is the ID of the second message. In this embodiment, the identifier refers to the above-mentioned 29-bit identifier, whose high 3 bits store the frame sequence number written when converting from the first message to the second message.

[0060] Step S502: Determine the second message group belonging to the same original message in the second message based on the identifier.

[0061] Specifically, all second messages are traversed, the lower 26 bits of the second message identifier are extracted and compared, and second messages with the same lower 26 bits are identified as belonging to the same original message second message group.

[0062] Step S503: Concatenate the data fields of the second message group to obtain the data field of the first message.

[0063] Specifically, further, the high 3 bits of any second message identifier in the second message group are extracted sequentially in ascending order of frame sequence number to form the target threshold byte number data field of each second message in the second message group, and these data fields are concatenated end to end to form the first message data field. For the concatenated first message data field, the padding bytes inserted when converting from the first message to the second message need to be removed to remove invalid padding data and obtain all valid data in the first message data field. The padding bytes to be removed can be confirmed by confirming the valid data based on the length of the corresponding data code, or by identifying a preset padding value.

[0064] Step S504: Based on the split identifier in the second signal attribute, several sub-signals in the second message group are spliced ​​together to obtain the first message signal field.

[0065] Specifically, for multiple second messages in the second message group, some second messages have a split identifier in their corresponding second signal attributes, indicating that the signals in the second message need to be concatenated to recover the complete signal. For second messages with split identifiers, they are concatenated in order according to the sequence number in the split identifier (e.g., "_split0", "_split1") to recover the complete signal before conversion from the first message. While concatenating the signals, the bit lengths of the signals with split identifiers need to be added to obtain the bit length of the signal corresponding to the first message. At the same time, according to the layout of the original first message or the byte alignment principle, the starting position of the concatenated complete signal in the data field of the first message needs to be calculated, while retaining all other signal attributes such as byte order, precision, and offset unchanged, and removing the split identifier to obtain the processed signal. Furthermore, the above-mentioned processed signal is integrated with the signals in the second message that do not have split identifiers to obtain the signal field of the first message.

[0066] Step S505: Generate a first message based on the first message data field and the first message signal field.

[0067] Specifically, the first message data field obtained in the above steps is used as the data payload of the first message, and the first message signal field obtained in the above steps is used as the database describing the data payload, thereby generating the corresponding first message. This achieves efficient, accurate and automated reverse conversion from multiple second messages to a single first message, and together with the conversion from the first message to the second message, it constitutes a complete bidirectional data conversion method, effectively ensuring the compatibility and reliability of data transmission under different protocols.

[0068] According to the data conversion method of this application embodiment, after obtaining the data structure of the original message, the data code length is compared with the target threshold length. Furthermore, data codes with a data code length not greater than the target threshold length and data codes with a data code length greater than the target threshold length are processed separately, and combined with signal attributes to be mapped into new data messages. The data conversion method provided by this application can efficiently and accurately convert data messages in two communication protocols, effectively improving data conversion efficiency while ensuring data accuracy, thereby effectively reducing faults caused by message errors.

[0069] refer to Figure 6 This is a schematic diagram of a data conversion device provided in an embodiment of this application.
