[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] In order to make the purpose, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] In an exemplary embodiment, a system based on LIN multi-channel parallel communication is provided, such as Figure 1 As shown, the system includes: a LIN communication unit, a multi-channel processing unit, a data processing unit, a data storage unit and a data acquisition unit. The LIN communication unit includes multiple parallel LIN communication modules. The multi-channel processing unit manages all LIN communication modules. Each data read by the LIN communication module is first passed to the multi-channel processing unit, and then the multi-channel processing unit transmits the data to the data processing unit. The data processing unit processes the data and filters out unnecessary data, and passes the normal data that needs to be processed to the data storage unit, which is then displayed by the data acquisition unit. Specifically:

[0042] The LIN communication unit is mainly used to obtain LIN data. LIN data includes: communication requirements and communication data of the communication object. Communication data includes one or more of communication speed, communication data volume and communication priority.

[0043] The multi-channel processing unit is connected to the LIN communication unit. The multi-channel processing unit is mainly used to configure the LIN communication module based on the LIN data, design and store the MFC (Microsoft Foundation Classes) interface of the communication data, and obtain multiple LIN channel data. The MFC interface includes the LIN message content, data length and sending node. Each LIN channel data includes multiple LIN messages and LIN message commands. Among them, each channel in the multi-channel processing unit is independent and can store multiple LIN message commands. In each channel, the content, data length, sending node, etc. of the LIN message can be set.

[0044] The data processing unit is connected to the multi-channel processing unit. The data processing unit is mainly used to process and parse multiple LIN channel data to obtain parsed data. The processing includes adding headers, checking, time synchronization processing, conflict mechanism processing and data filtering processing. In the actual application process, the data processed by the multi-channel processing unit is transferred to the data storage unit for storage. The data processing unit adds headers and checks to the LIN message, and processes the time synchronization and conflict mechanism on the LIN bus, processes and filters out the unnecessary parts of the message, and parses the data part and transfers it to the data storage unit.

[0045] The data storage unit is connected to the data processing unit. The data storage unit is used to store the parsed data. In the actual application process, the parsed data can be saved as N groups of LIN data.

[0046] The data acquisition unit is connected to the data storage unit and the LIN communication unit respectively. The data acquisition unit is used to send LIN data to the LIN communication unit, and to receive, store and display parsed data.

[0047] In another embodiment of the present application, the LIN protocol is usually a single bus protocol, so each LIN bus has only one physical channel. Each physical channel can have a master controller (Master) and multiple slave controllers (Slave), but these controllers share the same bus. Therefore, in traditional LIN communication, there is only one channel on each bus, so this application introduces the concept of multiple devices. Among them:

[0048] Multiple devices: In automotive electronic systems, various control units need to communicate. Each control unit is connected to the LIN bus, forming multiple channels.

[0049] LIN bus: LIN bus is used as the communication medium, and each channel is connected to the LIN bus. That is, multiple parallel LIN communication modules are connected to the multi-channel processing unit through the LIN bus.

[0050] Communication protocol: LIN communication usually uses a specific communication protocol. Devices on each channel must follow the same communication protocol in order to coordinate data transmission. The communication protocol includes message, frame and signal definitions to describe how the data is transmitted and what it means.

[0051] Data frame transmission: Each device on the channel can send and receive data frames. The data frame includes a message identifier (Message ID), a data field, and a checksum. Parallel communication means that multiple devices can send and receive data frames at the same time, thereby improving communication efficiency.

[0052] Time synchronization: Devices on the LIN bus require strict time synchronization to ensure that data is sent and received within the scheduled time. The devices on the channel are coordinated by a multi-channel processing unit to ensure that they send data at the appropriate time.

[0053] Conflict resolution: In multi-channel parallel communication, data conflicts may occur. If two devices try to send data at the same time, a conflict may occur. Before each data is sent on the LIN bus, a request is made to the multi-channel processing unit to determine whether it can be sent at the moment. Only when it is returned as being sendable can the data be sent normally, thereby achieving conflict detection and conflict resolution to ensure the integrity and accuracy of the data. Based on this, in actual application, before each data is sent on the LIN bus, a conflict detection request is sent to the multi-channel processing unit. The data processing unit receives the conflict detection request and performs conflict and error detection on the sent data.

[0054] When a conflict is detected in the transmitted data, a conflict resolution mechanism is triggered and the data transmission is completed according to the conflict resolution mechanism. The conflict resolution mechanism includes a frame priority processing mechanism, a backoff mechanism and / or a retry mechanism.

[0055] When an error is detected in the sent data, the data is retransmitted or an error report is generated.

[0056] When it is detected that there is no conflict or error in the transmitted data, the data is sent normally.

[0057] Error handling: In communication, errors may occur. The LIN communication protocol includes error detection and correction mechanisms to ensure reliable transmission of data. When errors occur, devices should be able to handle them, for example, retransmit or report the error.

[0058] In another embodiment of the present application, taking the parallel communication of automobile equipment as an example, the implementation process of the system based on LIN multi-channel parallel communication provided by the present application is described, specifically:

[0059] Step 1: Understand the communication requirements of each subsystem in the data acquisition unit, and understand the communication speed, data volume and priority of each subsystem. Place the data of each subsystem in the data storage unit and select the appropriate LIN communication module according to the configuration of the subsystem.

[0060] Step 2: Pack the data of the LIN communication module. The data of the LIN communication module includes the content of the LIN message, data length, sending node, etc.

[0061] Verify the LIN message header under each channel, and process information such as time synchronization and conflict mechanism on the LIN bus.

[0062] Step 3: Error handling and conflict detection mechanisms for LIN communication. Contains the following:

[0063] Frame Sync Field: Each LIN frame starts with a frame sync field, which is used to synchronize all devices. When the signal on the bus matches the frame sync field, the device starts receiving the frame.

[0064] Identifier identification: The message identifier field of the frame contains the identifier of the message. When the device starts receiving frames and detects the frame synchronization field, it compares the message identifier in the frame with the identifier list stored in itself. If the message identifier matches, the device considers the frame to be a message of interest to it and continues to receive it.

[0065] Detecting conflicts: If multiple devices try to send a message and start sending frames on the bus, conflicts may occur. This is because only one frame of data can be transmitted on the LIN bus, and when there are multiple competing frames at the same time, the transmission cannot be carried out. When transmitting a frame, the device will constantly detect the voltage level on the LIN bus to see if there are other devices sending data. If so, it will wait for the other device to finish sending before requesting to send.

[0066] Non-zero priority: There is a frame priority in LIN communication. Frames with lower message identifier values ​​usually have higher priority. Therefore, frames with lower message identifiers usually wait for other frames to complete transmission before transmission to avoid conflicts. If data is requested to be sent at the same time, it is sent in priority order. If there are other devices currently transmitting data, wait for other devices to complete transmission before transmitting data according to priority.

[0067] Step 4: The data acquisition unit collects the data returned by the multi-channel processing unit communication, collects the data of each channel and saves it to the database.

[0068] In another embodiment of the present application, the conflict resolution mechanism includes:

[0069] 1. Frame priority: When multiple devices send frames at the same time and a conflict occurs, the devices will compare the message identifiers. The frames with lower message identifier values ​​will have higher priorities. Other devices will usually temporarily give up sending until there are no higher priority frames, and then send data to wait for the conflicting frames to complete transmission.

[0070] For example, data transmission queue information is generated according to the priority of the frame for transmitting data, and after the current data transmission is completed, data transmission is performed according to the data transmission queue information. The lower the message identifier value of the frame, the higher the priority of the frame.

[0071] 2. Backoff mechanism: If a device detects a conflict, it will randomly generate a delay time and then wait for a period of time before trying to send again. This backoff time is random to reduce the possibility of a conflict occurring again.

[0072] 3. Retry mechanism: If a device encounters conflicts multiple times in a row, it may increase the backoff time or wait longer before trying to send again. This helps reduce the chance of repeated conflicts. For example, when conflicts are detected multiple times in a row, extend the delay time or set the backoff time, and send the data again according to the extended delay time or backoff time.

[0073] 4. Frame count: Each LIN communication module in LIN communication can be configured with a frame counter to track the number of frames sent. If the number of consecutively sent frames reaches the upper limit of the device's frame count, the device can stop sending to reduce conflicts.

[0074] Based on the above description, the multi-channel LIN network provided by the present application allows different subsystems to be isolated on different channels, which means that different LIN communication systems can run on independent channels, thereby reducing the possibility of communication conflicts.

[0075] Each channel can have a different communication speed and priority, which allows high-priority tasks (such as safety functions) to get a response in a shorter time, while low-priority tasks can run on slower channels, improving communication efficiency and flexibility to achieve intelligent communication based on LIN multi-channel parallelism.

[0076] Based on the same inventive concept, the embodiment of the present application also provides a method for implementing the above-mentioned LIN multi-channel parallel communication method. The implementation solution provided by the method is similar to the implementation solution recorded in the above-mentioned system, so the specific limitations in one or more LIN multi-channel parallel communication method embodiments provided below can refer to the above-mentioned limitations on the LIN multi-channel parallel communication system, which will not be repeated here.

[0078] Step 200: Receive LIN data. The LIN data includes: communication requirements and communication data of the communication object. The communication data includes one or more of communication speed, communication data volume and communication priority.

[0079] Step 201: Use the configured LIN communication module to communicate, and during the communication process, design and store the MFC interface of the communication data to obtain multiple LIN channel data.

[0080] Step 202: Process and parse multiple LIN channel data to obtain parsed data. The processing includes adding headers, performing verification, time synchronization processing, conflict mechanism processing, and data filtering processing.

[0081] Step 203: Store and collect parsed data.

[0082] As an optional implementation, the process of collecting and analyzing data in step 203 can be described as follows:

[0083] After obtaining the start frame of the parsed data and detecting the frame synchronization field of the start frame, compare the message identifier in the frame synchronization field of the start frame with the message identifier in the stored identifier list to see whether they match.

[0084] If they match, the collection of parsed data will continue. If they do not match, the collection of parsed data will be interrupted.
