Technical Field

[0001] This invention relates to the field of computer technology, and more specifically to data interaction methods, devices, and electronic devices. Background Technology

[0002] To ensure the security and real-time performance of data transmission between in-vehicle equipment and external devices, while also considering stability and cost requirements, in-vehicle equipment currently often retains only the CAN (Controller Area Network) or CANFD (CAN with Flexible Data rate) interface as the sole external signal interface. However, the CAN or CANFD interface is only used for transmitting real-time signals and cannot export various log files generated internally to external devices. Furthermore, it cannot support command-line interaction between external devices and in-vehicle equipment, thus failing to meet the debugging needs of in-vehicle equipment. Summary of the Invention

[0003] This invention provides a data interaction method, apparatus, and electronic device to solve the problems of being unable to export various log files generated internally by the device to external devices and being unable to support command-line interaction between external devices and in-vehicle devices.

The request parameters of the interaction request are obtained by the second control unit after obtaining the interaction request through the controller local area network bus channel or the variable rate controller local area network bus channel and parsing the interaction request. The request type of the interaction request is at least log reading and / or command execution.

[0006] The target data is divided into multiple target data packets according to a preset data volume, and these multiple target data packets are sent to the second control unit in sequence.

[0019] If a reception completion signal is not received from the second control unit within the preset time, or if a reception failure signal is received from the second control unit, the target data packet is resent to the second control unit.

[0020] Secondly, the present invention provides a data interaction method applied in a second control unit of an in-vehicle device, wherein the second control unit is communicatively connected to a first control unit of the in-vehicle device and external devices, the method comprising:

The request type of the interaction request is at least log reading and / or command execution.

[0026] The data packet sending module is used to divide the target data into multiple target data packets according to a preset data amount, and send the multiple target data packets to the second control unit in sequence.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] It is understood that before using the technical solutions disclosed in the various embodiments of the present invention, users should be informed of the types, scope of use, and usage scenarios of the personal information involved in the present invention and their authorization should be obtained in accordance with relevant laws and regulations through appropriate means.

[0048] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0049] To ensure the security and real-time performance of data transmission between in-vehicle equipment and external devices, while also considering stability and cost requirements, in-vehicle equipment currently often retains only the CAN (Controller Area Network) or CANFD (CAN with Flexible Data rate) interface as the sole external signal interface. However, the CAN or CANFD interface is only used for transmitting real-time signals and cannot export various log files generated internally to external devices. Furthermore, it cannot support command-line interaction between external devices and in-vehicle equipment, thus failing to meet the debugging needs of in-vehicle equipment.

[0050] To address the aforementioned technical problems, this invention provides a data interaction method applied to a first control unit of an in-vehicle device. The first control unit is communicatively connected to a second control unit of the in-vehicle device. The method responds to request parameters of an interaction request sent by the second control unit, performs data processing based on the request parameters to execute the interaction request and obtain the target data corresponding to the interaction request. The request parameters are obtained by the second control unit after parsing the interaction request received through a controller local area network (CLAN) bus channel or a variable-rate CLAN bus channel. The request type of the interaction request is at least log reading and / or command execution. The target data is divided into multiple target data packets according to a preset data volume, and these packets are sequentially sent to the second control unit. The preset data volume matches the transmission rate of the CLAN bus channel or the variable-rate CLAN bus channel. On the other hand, a data interaction method is also provided, applied to the second control unit of an in-vehicle device. The second control unit is communicatively connected to the first control unit of the in-vehicle device and external devices respectively. The method responds to an interaction request sent by an external device through a controller area network (CLAN) bus channel or a variable rate CLAN bus channel, parses the interaction request to obtain the request parameters of the interaction request, wherein the request type of the interaction request is at least log reading and / or command execution; sends the request parameters to the first control unit so that the first control unit executes the interaction request based on the request parameters to obtain multiple target data packets corresponding to the interaction request; obtains the multiple target data packets sent by the first control unit, and sends the multiple target data packets to the external device through the CLAN bus channel or the variable rate CLAN bus channel. Therefore, the second control unit of the vehicle-mounted equipment parses the interaction requests sent by external devices through the Controller Area Network (CLAN) bus channel or the variable-rate CLAN bus channel to obtain the request parameters. This enables the vehicle-mounted equipment to receive and identify log reading or command execution interaction requests through the CLAN bus channel or the variable-rate CLAN bus channel. Simultaneously, the first control unit of the vehicle-mounted equipment processes data based on the request parameters to execute the interaction requests. This allows the vehicle-mounted equipment to normally execute the interaction requests sent through the CLAN bus channel or the variable-rate CLAN bus channel, meeting the debugging requirements of the vehicle-mounted equipment. Furthermore, when returning the target data obtained from the execution of the interaction requests, the data is packetized and transmitted according to a preset data volume that matches the transmission rate of the CLAN bus channel or the variable-rate CLAN bus channel, thereby adapting to the transmission rate of the CLAN bus channel or the variable-rate CLAN bus channel and improving transmission efficiency.

[0051] The data interaction method provided in this invention can be applied to in-vehicle devices, providing comprehensive and reliable support for the diagnosis and debugging of these devices. The in-vehicle terminal includes a first control unit and a second control unit. The first control unit, as the core control unit of the in-vehicle device, manages and controls the entire device. The second control unit is a microprocessor used to manage the communication system of the in-vehicle device. The data interaction method provided in this invention does not require additional hardware or modification of existing hardware, ensuring hardware compatibility while meeting the debugging needs of in-vehicle devices.

[0052] According to an embodiment of the present invention, a data interaction method embodiment is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0053] In this embodiment, a data interaction method is provided, which can be used in the first control unit of the vehicle-mounted device, wherein the first control unit is communicatively connected to the second control unit of the vehicle-mounted device. Figure 1 This is a schematic diagram of the first type of data interaction method according to an embodiment of the present invention, such as... Figure 1 As shown, the process includes the following steps:

[0054] Step S101: In response to the request parameters of the interaction request sent by the second control unit, data processing is performed based on the request parameters to execute the interaction request and obtain the target data corresponding to the interaction request.

[0055] In this embodiment of the invention, the request parameters of the interaction request are obtained by the second control unit after it receives the interaction request through the controller LAN bus channel or the variable-rate controller LAN bus channel and parses the interaction request. The request type of the interaction request is at least log reading and / or command execution. It should be noted that the interaction request may include more request types that can be implemented by the current controller LAN bus channel or the variable-rate controller LAN bus channel, such as real-time signals, etc., which will not be elaborated on here.

[0056] In this embodiment of the invention, after receiving the request parameters of the interaction request sent by the second control unit, the first control unit performs corresponding data processing on the data area pointed to by the interaction request based on the request parameters, thereby completing the execution of the interaction request and obtaining the target data corresponding to the interaction request. Specifically, if the request type of the interaction request is log reading, the target data corresponding to the interaction request is the read log data; if the request type of the interaction request is command execution, the target data corresponding to the interaction request is the command execution result.

[0057] Step S102: The target data is divided into multiple target data packets according to a preset data volume, and the multiple target data packets are sent to the second control unit in sequence.

[0058] In this embodiment of the invention, the preset data volume is matched with the transmission rate of the controller LAN bus channel or the variable-rate controller LAN bus channel, thereby improving the transmission rate of a single data packet, avoiding timeouts in the transmission of a single data packet, and reducing the risk of data loss. The target data is packetized according to the preset data volume to obtain multiple target data packets, and these multiple target data packets are sequentially sent to the second control unit according to the packetization order, so that the second control unit can transmit the target data packets to external devices.

[0059] This embodiment provides a data interaction method that can be used in the first control unit of an in-vehicle device, wherein the first control unit is communicatively connected to the second control unit of the in-vehicle device. Figure 2 This is a schematic diagram of a second type of data interaction method according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps:

[0060] Step S201: In response to the request parameters of the interaction request sent by the second control unit, data processing is performed based on the request parameters to execute the interaction request and obtain the target data corresponding to the interaction request.

[0061] In this embodiment of the invention, the request type of the interaction request is determined based on the request parameters of the interaction request. The request parameters of the interaction request include at least a request type field or identifier. This request type field or identifier can be a request identifier field defined in the protocol header of the interaction request, a request path of the interaction request, or a command prefix of the interaction request, used to uniquely identify and distinguish an interaction request of a certain type. Furthermore, the type of the interaction request can be further confirmed by combining the business parameters in the request parameters. For example, if the business parameters include log location information, such as a log module ID, the request type of the interaction request can be confirmed as log reading; if the business parameters include a command string for the interaction request, the request type of the interaction request can be confirmed as command execution.

[0062] In this embodiment of the invention, if the request type of the interaction request is log reading, then step S201 may include:

[0063] Step S2011: Based on the log location information in the request parameters, filter the logs of the vehicle-mounted device to obtain the log file corresponding to the interaction request.

[0064] In this embodiment of the invention, log location information is used to locate the log module containing the log to be read. The log location information includes at least the log module ID and may also include limiting information about the log to be read, such as the time range of the log to be read. Based on the log location information in the request parameters, the logs of the vehicle-mounted device are searched and located to obtain the target log to be read by the interaction request. If the log location information further includes limiting information about the log to be read, the located target log is filtered based on this limiting information. For example, if the limiting information includes the time range of the log to be read, then logs with timestamps within that time range are filtered to obtain the log file corresponding to the interaction request.

[0065] Step S2012: Compress the log file corresponding to the interaction request to obtain the target data corresponding to the interaction request.

[0066] In this embodiment of the invention, the selected log files are packaged and compressed into a gz format compressed file using the tar command, and this compressed file is used as the final target data fed back to the external device to reduce the amount of data transmitted.

[0067] In one optional implementation, after compressing the log file corresponding to the interaction request to obtain the target data corresponding to the interaction request, the target data corresponding to the interaction request is stored in a temporary file so that the target data can be transmitted in packets later.

[0068] Step S202: The target data is divided into multiple target data packets according to a preset data size, and these multiple target data packets are sent sequentially to the second control unit. For details, please refer to [link to relevant documentation]. Figure 1 Step S102 of the illustrated embodiment will not be described again here.

[0069] This embodiment provides a data interaction method that can be used in the first control unit of an in-vehicle device, wherein the first control unit is communicatively connected to the second control unit of the in-vehicle device. Figure 3 This is a schematic diagram of a third type of data interaction method according to an embodiment of the present invention, such as... Figure 3 As shown, the process includes the following steps:

[0070] Step S301: In response to the request parameters of the interaction request sent by the second control unit, data processing is performed based on the request parameters to execute the interaction request and obtain the target data corresponding to the interaction request.

[0071] In this embodiment of the invention, the request type of the interaction request is determined based on the request parameters of the interaction request. The request parameters of the interaction request include at least a request type field or identifier. This request type field or identifier can be a request identifier field defined in the protocol header of the interaction request, a request path of the interaction request, or a command prefix of the interaction request, used to uniquely identify and distinguish an interaction request of a certain type. Furthermore, the type of the interaction request can be further confirmed by combining the business parameters in the request parameters. For example, if the business parameters include log location information, such as a log module ID, the request type of the interaction request can be confirmed as log reading; if the business parameters include a command string for the interaction request, the request type of the interaction request can be confirmed as command execution.

[0072] In an optional implementation, if the request type of the interaction request is command execution, then step S301 includes:

[0073] Step S3011: Parse the command string in the request parameters to obtain the request command corresponding to the interactive request.

[0074] In this embodiment of the invention, the command string contains at least the command name corresponding to the interaction request, and may also contain command parameters corresponding to the interaction request. The command string is split along spaces to separate it into the command name and command parameters, thus obtaining the request command for the interaction request. If the command string does not contain spaces, it indicates that it does not contain command parameters, and the resulting request command is a five-parameter command.

[0075] In one optional implementation, after parsing the request command corresponding to the interactive request, it is determined whether the request command conforms to the command restriction rules. If it conforms to the command restriction rules, the further request command is executed. The command restriction rules may include the following: the command length is a maximum of 63 characters and ends with \0; commands ending with \n are not supported, such as "cat / log / sys.txt\n"; continuous execution commands are not supported, such as top and tail -f.

[0076] Step S3012: Execute the request command corresponding to the interaction request to obtain the target data corresponding to the interaction request.

[0077] In this embodiment of the invention, the parsed request command is executed to perform the interactive request, and the execution result of the request command is used as the target data corresponding to the interactive request fed back to the external device.

[0078] In one alternative implementation, the execution result of the request command corresponding to the interaction request is directed to a temporary file so that the target data is stored in the temporary file for subsequent packet transmission.

[0079] In one alternative implementation, the target data is compressed when it is stored in a temporary file. The target data is packaged and compressed using the `tar` command into a `.gz` format compressed file to reduce the amount of data transferred.

[0080] Step S302: The target data is divided into multiple target data packets according to a preset data size, and these multiple target data packets are sent sequentially to the second control unit. For details, please refer to [link to relevant documentation]. Figure 1 Step S102 of the illustrated embodiment will not be described again here.

[0081] This embodiment provides a data interaction method that can be used in the first control unit of an in-vehicle device, wherein the first control unit is communicatively connected to the second control unit of the in-vehicle device. Figure 4 This is a schematic diagram of the fourth process of the data interaction method according to an embodiment of the present invention, such as... Figure 4 As shown, the process includes the following steps:

[0082] Step S401: In response to the request parameters of the interaction request sent by the second control unit, data processing is performed based on the request parameters to execute the interaction request and obtain the target data corresponding to the interaction request. For details, please refer to [link to details]. Figure 1 Step S101 of the illustrated embodiment will not be described again here.

[0083] Step S402: The target data is divided into multiple target data packets according to a preset data volume, and the multiple target data packets are sent to the second control unit in sequence.

[0084] In this embodiment of the invention, when the target data is divided into packets according to a preset data volume, the packet sequence number of each target data packet is recorded according to the packet division order, and the total number of target data packets is counted to verify the data integrity of subsequent target data packet transmissions based on the packet sequence number and the total number. Accordingly, in step S402, multiple target data packets are sequentially sent to the second control unit, including:

[0085] Step S4021: If a reception completion signal is received from the second control unit, the next target data packet is sent to the second control unit according to the packet sequence number of the target data packet.

[0086] In this embodiment of the invention, the reception completion signal is sent from the second control unit to the first control unit after successfully receiving a target data packet. If the reception completion signal is received from the second control unit, it indicates that the currently transmitted target data packet has been successfully transmitted to the second control unit. Therefore, according to the packet sequence number of the target data packet, the next target data packet corresponding to the next packet sequence number is sent to the second control unit. The packet sequence number of the target data packet is determined based on the packet order of the target data.

[0087] In this embodiment of the invention, for the target data packet with packet sequence number 1, which is the first target data packet, if no target data packets have been transmitted before it, the target data packet is transmitted after the data packet is completed, and the first target data packet is sent to the second control unit. For target data packets with packet sequence number 2 and thereafter, the target data packets are transmitted according to the reception completion signal fed back by the second control unit.

[0088] Step S4022: If a reception completion signal is not received from the second control unit within a preset time, or a reception failure signal is received from the second control unit, the target data packet is resent to the second control unit.

[0089] In this embodiment of the invention, if a reception completion signal is not received from the second control unit within a preset time, it indicates that the transmission of the current target data packet has timed out. If a reception failure signal is received from the second control unit, it indicates that the transmission of the current target data packet has failed. At this time, the target data packet is resent to the second control unit for retransmission. The number of retransmissions is recorded. When the number of retransmissions of a target data packet reaches a preset number, it indicates that the data transmission has failed, and the transmission of the target data ends. At the same time, the second control unit can send a fault signal indicating data transmission failure to an external device.

[0090] In this embodiment, on the other hand, a data interaction method is provided, which can be used in the second control unit of an in-vehicle device. The second control unit is communicatively connected to the first control unit of the in-vehicle device and external devices, respectively. Figure 5 This is a schematic diagram of the fifth type of data interaction method according to an embodiment of the present invention, such as... Figure 5 As shown, the process includes the following steps:

[0091] Step S501: In response to an interaction request sent by an external device through a controller local area network (CLAN) bus channel or a variable rate CLAN bus channel, the interaction request is parsed to obtain the request parameters of the interaction request.

[0092] In this embodiment of the invention, since the external device sends an interaction request through the Controller Area Network (CLAN) bus channel or the variable-rate CLAN bus channel, and the CLAN bus channel or the variable-rate CLAN bus channel uses the UDS diagnostic protocol for data transmission, the interaction request is sent to the second control unit using the UDS diagnostic protocol. The second control unit parses the interaction request and extracts the request parameters. The request type of the interaction request is at least log reading and / or command execution. It should be noted that the interaction request can include more request types that the current CLAN bus channel or the variable-rate CLAN bus channel can implement, such as real-time signals, etc., which will not be elaborated further here.

[0093] Step S502: Send the request parameters to the first control unit so that the first control unit executes the interaction request based on the request parameters and obtains multiple target data packets corresponding to the interaction request.

[0094] In this embodiment of the invention, after parsing the request parameters, the request parameters are sent to the first control unit so that the first control unit executes the interaction request based on the request parameters, obtains the target data corresponding to the interaction request, and then packages the target data into multiple target data packets and sends them to the second control unit.

[0095] Step S503: Obtain multiple target data packets sent by the first control unit, and send the multiple target data packets to external devices through the controller LAN bus channel or the variable rate controller LAN bus channel.

[0096] In this embodiment of the invention, after receiving all the target data packets, the second control unit uses the UDS diagnostic protocol to send multiple target data packets to external devices via the controller LAN bus channel or the variable rate controller LAN bus channel, so that the external devices can decompress and restore the target data packets after receiving all the target data packets to obtain the data they need.

[0097] In one specific implementation, Figure 6 This is a schematic diagram of the interaction when the request type of the interaction request is log reading in the data interaction method of this embodiment of the invention, as shown in the figure. Figure 6 As shown, depending on the function and the operation performed, the first control unit may include at least a data processing unit and a log filtering and packaging unit. The data processing unit is responsible for identifying the request type of the interaction request parameters sent by the second control unit. When the request type is identified as log reading, the log filtering and packaging unit is invoked to read the logs. The first and second control units use inter-core communication for data transmission and interaction. Figure 6As shown, the external device sends a log read request to the in-vehicle device using a diagnostic protocol. The second control unit directly receives this log read request, parses it, and sends the parsed request parameters to the data processing unit of the first control unit via inter-core communication. Upon receiving the request parameters, the data processing unit identifies it as a log read request, calls the log filtering and packaging unit, filters the logs according to the request parameters, obtains the filtered log file, and performs a packaging and compression operation. The compressed target data is stored in a temporary file. After storing the target data in the temporary file, the target data is divided into packets with a preset data size of 2KB. The data processing unit performs serial packet transmission according to the packet order, sequentially returning the target data packets corresponding to the interaction request. After receiving the target data packet, the second control unit sends a reception completion signal to the first control unit. Upon receiving the reception completion signal, the first control unit continues to transmit the next target data packet according to the packet order until all target data packets are transmitted to the second control unit. After receiving all target data packets, the second control unit transmits all target data packets to the external device using the diagnostic protocol, thus completing the response and feedback of the in-vehicle device to the interaction request from the external device.

[0098] In one specific implementation, Figure 7 This is a schematic diagram illustrating the interaction method of the present invention, where the request type of the interaction request is command execution. Figure 7 As shown, depending on the function and the operation performed, the first control unit may include at least a data processing unit and a command execution and result capture unit. The data processing unit is responsible for identifying the request type of the interaction request parameters sent by the second control unit. When the request type is identified as command execution, the command execution and result capture unit is invoked to execute the command. The first and second control units communicate and interact via inter-core communication. Figure 7As shown, the external device sends a command request to the vehicle-mounted device using a diagnostic protocol. The second control unit directly receives the command request, parses it, and sends the parsed request parameters to the data processing unit of the first control unit via inter-core communication. Upon receiving the request parameters, the data processing unit identifies it as a command request, parses the command string in the request parameters, and calls the command execution and result capture unit to execute the command. Simultaneously, the execution result is redirected to a temporary file so that the command execution and result capture unit can return the execution result to the temporary file after execution. The data processing unit performs a compression operation, and after compression, the data is packetized into pre-defined 2KB packets. The data processing unit performs serial packet transmission according to the packet order, sequentially returning the target data packets corresponding to the interaction requests. After receiving the target data packet, the second control unit sends a reception completion signal to the first control unit. Upon receiving the reception completion signal, the first control unit continues to transmit the next target data packet according to the packet order until all target data packets are transmitted to the second control unit. After receiving all target data packets, the second control unit transmits all target data packets to external devices using a diagnostic protocol, thereby completing the response and feedback of the vehicle equipment to the interaction requests of external devices.

[0099] The data interaction method provided in this invention involves the second control unit of the vehicle-mounted device parsing interaction requests sent by external devices through a controller local area network (CLAN) bus channel or a variable rate CLAN bus channel to obtain request parameters. This enables the vehicle-mounted device to receive and identify log reading or command execution interaction requests through the CLAN bus channel or the variable rate CLAN bus channel. Simultaneously, the first control unit of the vehicle-mounted device processes data based on the request parameters to execute the interaction requests. This allows the vehicle-mounted device to normally execute the interaction requests sent through the CLAN bus channel or the variable rate CLAN bus channel, meeting the debugging requirements of the vehicle-mounted device. Furthermore, when returning the target data obtained from the execution of the interaction requests, the data is packetized and transmitted according to a preset data volume that matches the transmission rate of the CLAN bus channel or the variable rate CLAN bus channel, thereby adapting to the transmission rate of the CLAN bus channel or the variable rate CLAN bus channel and improving transmission efficiency.
