[0027] For the convenience of description, some nouns or terms involved in the embodiments of the present application are explained below:

[0028] MCU: Microcontroller Unit, micro control unit;

[0029] SOC: System on chip;

[0030] CAN: Controller Area Network, controller area network;

[0031] TSN: Time-Sensitive Networking, time-sensitive network;

[0032] PHY: Physical, physical layer.

[0033] As mentioned in the background technology, in the prior art, controllers of traditional automobiles mainly communicate with each other through the CAN bus, but this can no longer meet the needs of massive data and high bandwidth, thus leading to the technical problem of large data transmission delay between modules. In order to solve the above problem, in a typical implementation of the present application, a data communication method and device, a vehicle and an electronic device are provided.

[0034] According to an embodiment of the present application, a data communication method is provided.

[0035] The present application provides an Ethernet switch, the specific schematic diagram is as follows Figure 1 As shown, the Ethernet switch is provided with a plurality of scheduling interfaces, which are respectively connected to a plurality of system chips, an Ethernet physical layer and a plurality of terminal devices. Specifically, in the embodiment provided by the Ethernet switch schematic diagram, the Ethernet switch is connected to SOC1, SOC2, SOC3 and MCU through the scheduling interface, and is also connected to the Ethernet physical layer.

[0036] Figure 1In the specific embodiment shown, the switch Ethernet circuit includes five interfaces of the switch, which are connected to MCU, PHY, SOC1, SOC2, and SOC3 respectively, and all adopt RGMII working mode. AVB and TSN are supported. AVB mainly provides three functions: reserved bandwidth, traffic priority, and time synchronization. TSN extends two functions based on AVB, mainly time scheduling traffic and preempting frames.

[0037] It should be noted that TSN includes multiple protocols such as 802.1AS-Rev, 802.1Qbv, 802.1Qbu, and 802.1CB. Global clock synchronization is an important mechanism for achieving deterministic communication among network nodes. 802.1AS-Rev supports and is compatible with time synchronization between different TSN devices, while increasing support for fault tolerance and multiple master clock sources. 802.1Qbv creates and distributes a time schedule between participating network devices to control the valve switch of the sending queue at the exit of the TSN switch.

[0038] Figure 2 1 is a flow chart of a data communication method provided according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0039] Step S201, obtaining a data transmission list of a target system chip, wherein the data transmission list defines a plurality of data queues to be transmitted and transmission times of the plurality of data queues;

[0040] As described above, in the present application, for each system chip, a data transmission list corresponding to the system chip is defined, and the list defines a plurality of data queues to be transmitted corresponding to the system chip and a transmission time corresponding to each queue.

[0041] Step S202, when it is detected that the sending time of the target data queue in the data sending list has arrived, determining a target scheduling interface for transmitting the target data queue, wherein the target data queue is any one of the multiple data queues;

[0042] Step S203, control the target queue sub-valve corresponding to the target scheduling interface to open, so that the target data queue is sent to the target terminal device through the target scheduling interface, wherein the target queue sub-valve is a software valve defined by a bit value, and the target scheduling interface corresponds to the target queue sub-valve one by one.

[0043] As described above, since each system chip corresponds to multiple data queues to be sent, the present application defines a queue valve for multiple terminals connected to the Ethernet switch corresponding to the multiple data queues, wherein the queue valve includes multiple queue sub-valves, and each scheduling interface corresponds to a queue sub-valve one by one.

[0044] Therefore, this application defines planned traffic, and after the data queue where the planned traffic is located arrives in the predetermined time window, the data queue is released for transmission through the queue sub-valve, while other queues of unplanned traffic in the same time window will be blocked from transmission, thereby eliminating the possibility of planned traffic being blocked by unplanned traffic, which means that the delay through each switch is certain, and the message delay through the TSN network can be guaranteed.

[0045] In an optional embodiment, before controlling the target queue sub-valve corresponding to the target scheduling interface to open so that the target data queue is sent to the target terminal device through the target scheduling interface, the method includes: determining multiple terminal devices connected to multiple scheduling interfaces, and determining multiple bits corresponding to the multiple terminal devices; assigning multiple first numerical values ​​to multiple bits, and generating a character string based on the multiple first numerical values, wherein when the value on the bit is the first numerical value, the queue sub-valve corresponding to the bit is in a closed state; defining the character string as a communication valve in a closed state, wherein the communication valve includes multiple queue sub-valves, and each bit corresponds to a target queue sub-valve.

[0046] In the above, the queue valve is represented by an 8-bit binary string (XXXXXXXX). From right to left, the first bit on the right represents the switch state of queue 0, the second bit on the right represents the switch state of queue 1, and so on. When a bit is 0, it means off, that is, the message in the queue is not allowed to be sent; when a bit is 1, it means on, that is, the message in the queue is allowed to be sent. It should be noted that when there is no data queue to be transmitted through the Ethernet switch, the values ​​of all bits are 0.

[0047] In an optional embodiment, controlling the target queue sub-valve corresponding to the target scheduling interface to open includes: controlling the value on the bit corresponding to the target queue sub-valve to be changed to a second value, so that the target queue sub-valve is opened. While controlling the target queue sub-valve corresponding to the target scheduling interface to open, the method also includes: controlling the values ​​on the bits corresponding to the non-target queue sub-valves to remain at the first value. When it is necessary to control the target queue sub-valve to open or close, it is only necessary to control the value on the corresponding queue sub-valve to change.

[0048] In an optional embodiment, when it is detected that the sending time of the target data queue in the data sending list has been reached, a target scheduling interface for transmitting the target data queue is determined, including: when it is detected that the sending time of the target data queue has been reached, a target terminal device for receiving the target data queue is determined; the MAC address of the target terminal device is obtained, and the target scheduling interface is determined based on the MAC address, wherein the scheduling interface corresponds one-to-one to the MAC address.

[0049] The above places, such as Figure 3 As shown, Figure 3 The schematic diagram of the system chip sending a data queue to a terminal. In this schematic diagram, by determining the address of the terminal receiving the data queue, the scheduling interface of the Ethernet switch connected to the terminal can be determined. As shown in the figure, there are three terminals in this example, and the terminal addresses are MAC: 1-1-1, 2-2-2, and 3-3-3. Among them, the message sent by SOC (MAC address is 10-10-10) to Terminal 1 (MAC address is 1-1-1) enters queue 0, the message sent by SOC to Terminal 2 (MAC address is 2-2-2) enters queue 1, and the message sent by SOC to Terminal 3 (MAC address is 3-3-3) enters queue 3.

[0050] Among them, node 1 is used to control the message sent by SOC to Terminal 1, the queue sub-switch state is 1 (the corresponding binary number is 00000001), and the switch state lasts for 200000 nanoseconds;

[0051] Node 2 is used to control the message sent from SOC to Terminal 2. The queue sub-switch state is 2 (the corresponding binary number is 00000010), and the switch state lasts for 300000 nanoseconds.

[0052] Node 3 is used to control the message sent by SOC to Terminal 3. The queue sub-switch state is 8 (the corresponding binary number is 00001000), and the switch state duration is 100000 nanoseconds. Among them, the opening duration of the queue sub-switch is the sending duration of the data queue pre-defined in the data sending list.

[0053] In an optional embodiment, when the target queue sub-valve corresponding to the target scheduling interface is controlled to be opened, the method also includes: when it is detected that there is at least one non-target data queue in the data queue to be passed through the target queue sub-valve at the same time, determining multiple priorities corresponding to at least one non-target data queue and the target data queue respectively; determining the data queue with the highest priority, and controlling the data queue with the highest priority to pass through the target queue sub-valve first.

[0054] As mentioned above, the queue valve provided by the present application can protect critical messages from interference from other network traffic, but it does not necessarily lead to optimal bandwidth usage or minimal communication delay. When these factors are important, the preemption mechanism defined in 802.1Qbu can be used. 802.1Qbu allows the interruption of the transmission of standard Ethernet or jumbo frames to allow the transmission of high priority frames, and then resumes the transmission without discarding the interrupted message fragments that were previously transmitted.

[0055] Figure 4 The transmission diagram of the data queue provided in this application is as follows: Figure 4 As shown in the figure, data 1 is critical information, data 2 is non-critical information, and data 2 arrives first and starts to be transmitted. In the MAC with preemptive mechanism, when data 1 arrives, the transmission of data 2 is allowed to be interrupted, and data 1 is transmitted first. After data 1 is transmitted, data 2 will be transmitted. This ensures that critical information can be transmitted earlier.

[0056] This application provides a data communication method and Ethernet switch, defines queue valves and data queue priorities, ensures the quality and real-time performance of data transmission, and uses the TSN mechanism to implement the time scheduling flow and preemptive frame mechanism of data. Therefore, the vehicle Ethernet communication system of this application improves the communication rate between traditional vehicle controllers and can be better applied to technical fields such as ADAS, L2, and L2+; at the same time, the AVB and TSN mechanisms adopted by the vehicle Ethernet communication system ensure the data quality and real-time performance when the data is transmitted through Ethernet, and the communication delay between each electronic module is lower.

[0057] An embodiment of the present application also provides a vehicle, which includes an Ethernet switch and a data communication device. The Ethernet switch is provided with multiple scheduling interfaces, and the multiple scheduling interfaces are respectively connected to multiple system chips, Ethernet physical layers and multiple terminal devices. The data communication device executes a data communication method.

[0058] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.
