Description

Technical Field

[0001] The present invention relates to the field of vehicle-mounted communication technology, and in particular to an adaptive and efficient CAN and Ethernet translation system, device and storage medium. Background Art

[0002] With the rapid development of the automotive industry, the networking properties of vehicles are constantly enhanced, and the demand for data exchange inside and outside the car has increased sharply. Modern cars use a variety of communication protocols, such as CAN (Controller Area Network) and Ethernet, to achieve data transmission between different electronic control units (ECUs). CAN bus is widely used in internal automotive communications due to its high reliability and low cost, while Ethernet has gradually become the main protocol for external automotive communications due to its high-speed transmission capability and wide network support. In order to achieve efficient interconnection and intercommunication between different protocols, communication gateways play an important role in vehicle networks. Communication gateways translate data from different protocols to achieve cross-system functional linkage and meet the increasingly complex vehicle communication needs.

[0003] Existing communication gateways usually use fixed routing tables and translation rules, and implement translation routing of different protocol data by modifying the gateway software. Common translation schemes include encapsulating CAN data packets into Ethernet data packets, or disassembling Ethernet data packets into multiple CAN data packets. Although these schemes are simple to implement, they have some limitations in practical applications. For example, traditional translation methods require pre-definition of routing tables and signal combinations during the design phase. Once the system is put into operation, any modifications require rewriting and testing the software, increasing the cost of development and maintenance. In addition, the existing translation methods process data packets in a relatively rough manner and lack refined management of data content, resulting in low communication efficiency.

[0004] The shortcomings of the existing technology are mainly reflected in the following aspects: First, the fixed routing table and translation rules limit the flexibility of the system and cannot adapt to complex and changeable application scenarios. For example, when the vehicle is modified or the system is upgraded, the gateway software needs to be modified frequently, which increases the workload of development and testing. Secondly, the existing translation method has a relatively simple way of processing data packets and lacks refined management of data content, resulting in low communication efficiency. For example, the traditional method requires the entire CAN data packet to be encapsulated into an Ethernet data packet. Even if only a small part of the data is really needed, the entire data packet must be transmitted, increasing the communication overhead. Finally, the existing translation method lacks intelligent dynamic configuration function, and cannot automatically adjust the routing strategy according to the real-time network status and data requirements, affecting the overall performance of the system. Summary of the invention

[0005] In view of the above defects or improvement needs of the prior art, the purpose of the present invention is to provide an adaptive and efficient CAN and Ethernet translation system, device and storage medium. The system inserts feature identification codes into data, segments the data domain and defines the data flow path through a data pre-shaping module. The data signal can be parameterized instead of addressed, so as to realize data capture and movement, avoid the traditional traversal query idea based on the address as the only principle, greatly shorten the calculation steps of the data forwarding routing process, reduce the forwarding communication overhead of non-demand data, and effectively improve the routing translation efficiency; at the same time, provide a host computer interface, extract effective data packets when the gateway forwards, provide fast and convenient dynamic configuration and even have certain adaptive routing processing functions. There is no need to pay attention to the address information of the underlying signal during dynamic configuration, so as to realize the decoupling of the application layer and the underlying layer. The dynamic configuration is efficient, the technical operability is simple and practical, and it is more in line with the actual needs of the application modification field.

[0043] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

It should be further understood that the term "comprising" used in the specification of the present application refers to the presence of the features, integers, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or combinations thereof.

[0045] It will be understood by those skilled in the art that, unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meaning as the general understanding of those skilled in the art to which this application belongs. It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as in the context of the prior art, and will not be interpreted with an idealized or overly formal meaning unless specifically defined as in the embodiments of this application.

[0046] The existing technical solution is mainly a PDU routing solution for translating someip Ethernet protocol messages and CAN messages. For messages that need to be translated into CAN messages, they are first defined and preset according to the CAN message PDU, and then loaded into the payload data area of ​​Ethernet. The rule is mainly composed of CANID+Length+CAN Payload. If multiple CAN PDUs need to be output at one time, they are arranged and filled in sequence. The existing solution is relatively easy to understand, the function is relatively simple, and the software implementation is easy, but its routing strategy is too simple and rough, and the routing table needs to be defined in advance. Both the source network segment and the target network segment need to have self-defined conditions to execute. There are many constraints on the scope of application, which is not suitable for many places that require modification design or compatibility design; at the same time, it routes the payload of the entire CAN data packet, and its usability is not strong and the actual efficiency is not high. According to statistics, in the practical design process, the actual effective signal content may be scattered in multiple CAN data packets, but the existing conventional solution needs to be encapsulated into MAC frames through multiple CAN_PDUs, which has high communication overhead and low communication efficiency.

[0047] The present invention provides an adaptive and efficient CAN and Ethernet translation system, device and storage medium. The system inserts a feature identification code into data, segments and slices the data domain and defines the data flow path through a data pre-shaping module, and can parameterize data signals instead of addressing them, so as to achieve data capture and movement, avoid the traditional traversal query idea based on the address as the only principle, greatly shorten the calculation steps of the data forwarding routing process, reduce the forwarding communication overhead of non-demand data, and effectively improve the routing translation efficiency; at the same time, a host computer interface is provided, and effective data packets are extracted when the gateway forwards, so that fast and convenient dynamic configuration is provided and even has a certain adaptive routing processing function. During dynamic configuration, there is no need to pay attention to the address information of the underlying signal, so as to achieve decoupling of the application layer and the underlying layer, and the dynamic configuration is efficient, simple and practical in technical operability, and more in line with the actual needs of the application modification field.

[0048] Embodiment 1:

[0049] As a comparison, the embodiment of the present invention first provides an existing network architecture, such as Figure 2As shown, ECU C (Ethernet node) needs the data signals (a3, a5, a8, b4, b7) of communication node A (CAN node) and communication node B (CAN node); if the conventional market solution is followed, the central gateway will disassemble the PDU of the two data packets CANID (0x18FF2132) and CANID (0x18FF3921) from ECUA and ECUB, and directly load them into the data field of the Ethernet MAC frame. Among them, ECU C needs to traverse the content of the data field of all Ethernet MAC frames according to the definition of the required signal, find the required data signal (a3, a5, a8, b4, b7), and then pass the data to the upper layer. After the upper layer application obtains the data, it performs data calculation according to the application function program logic that has been written, and the function is realized. From this we can see that although the gateway is simple to operate, its efficiency is low. Its effective signal data is only the data signal (a3, a5, a8, b4, b7), which is 24 bits. However, the actual data volume that needs to be transmitted is at least two CAN headers (29bit+29bit) plus two CAN data domains (64bit+64bit). The actual effective communication efficiency is only 12.9%. This situation is only when the signal comes from two CAN packets. If there are three or more different CAN data packets, the actual effective communication efficiency will be lower. In the actual development process, it is usually less than 10%. Another shortcoming is that if the ECU upper software needs to call the required signal, it cannot be quickly retrieved. It usually needs to read each bit of data in the CANPDU in sequence through traversal operations until all the required data are read and copied and called back. Assuming that a certain data is at the end of the data domain, it needs to start from the first bit and read one by one until the required data is read out. Its processing efficiency is insufficient, which can be seen.

[0050] The method for defining a signal set field provided in this embodiment can extract signal features in batches and perform centralized preprocessing to quickly meet the needs of the receiving end. At the same time, it supports intelligent dynamic configuration to meet the needs of adaptive modification applications.

[0051] The following still takes the above demand case as an example. Figure 3 Figure 4 As shown, the signal set field is defined. This field only occupies 2 bytes and is used to characterize the starting address and length of the signal, so that the gateway can flexibly extract and integrate on demand. The specific explanation method is as follows:

[0052] 1) The control word occupies 3 bits and is used to represent the signal set rule. The specific meanings are as follows: 0 means 4-bit rule method, 1 means 2-bit rule method, 2 means mixed rule method, and 3 means 8-bit rule method. Among them, the mixed identification method is the most commonly used.

[0053] 2) The number of signals occupies 5 bits and is used to represent the number of signals contained in this CAN data packet;

[0054] 3) Corresponding signal length: This field is usually 1 byte long, and usually defines the length of 8 groups of signals in sequence; this field is controlled by the control word. If the control word is 0, 1, or 3, it can be defined according to the detailed rules; it should be noted that if it is 2, that is, the mixed rule method, it is necessary to pay attention to the continuous 000 being represented as a 2-bit length signal, the continuous 001 being represented as a 4-bit length signal, and the continuous 011 being represented as an 8-bit signal. The following table is an example of the characterization method for better understanding.

[0055] Through this method, CAN data can be effectively organized. At the gateway, only the open interface configuration is required to effectively combine multiple CANs. If the signals (a1, a3, a5) in ECU-A and (b6, b7, b9) in ECU-B are required, for the central gateway, only data capture is required, and the data corresponding to these six signals are loaded into the PDU of the MAC frame. At this time, the data effectively transmitted in the MAC frame is the valid data of ECU-C itself, and there is no other irrelevant data, and the communication overhead is greatly reduced. If the ECU on the demand side of the gateway is changed to another ECU, such as ECU-D, the required signal is (a3\a4\a5)(b6\b8), then it only needs to be configured on the gateway side through the host computer to input the unpacking capture code to achieve it. This example is only a translation and extraction case of 2 different CAN packets. If there are multiple CAN packets, the effect will be more obvious.

[0056] like Figure 5 Figure 6 As shown in the figure, if the source network segment data can be defined independently, when it is CAN or CANFD data, in its data domain, a signal collection field is defined, and the signal collection field contains the following contents: number of signals n, signal number array a, signal sequence b, signal length c array; all signal data are filled starting from byte0bit0 as the starting address. The function of this collection field is to greatly shorten the calculation steps of the data forwarding routing process and reduce the forwarding communication overhead of non-demand data; at the same time, it provides an upper computer interface to extract effective data packets when the gateway forwards, providing fast and convenient dynamic configuration and even having certain adaptive routing processing functions.

[0057] Embodiment 2:

[0058] like Figure 1As shown, based on Example 1, an embodiment of the present invention provides an adaptive and efficient CAN and Ethernet translation system, including: a data packet detection module, used to detect the incoming data packet and determine whether the data type is non-autonomous defined data or autonomous defined data; a data pre-shaping module, used to define the signal set field of the non-autonomous defined data, including inserting one or more of the signal number, signal length identifier, signal sequence identifier, signal quantity identifier or control word information, and performing data domain segmentation and data flow path definition. The specific process is as follows Figure 7 As shown; a data path analysis module is used to perform data path decoding on the autonomously defined data or the pre-shaped non-autonomously defined data packet; a data composition analysis module is used to perform detailed signal-level disassembly on the data packet after the data path decoding to form a signal-level data packet to be sent; a data load analysis module is used to comprehensively evaluate the size of the signal-level data packet to be sent, determine the data forwarding transmission rule, load the data packet according to the transmission rule, and obtain the loaded data packet. The specific process is as follows Figure 8 As shown; a data sending module is used to send the loaded data packet according to the sending queue sequence list.

[0059] Specifically, the system performs overall identification and analysis of data frame types through a data packet detection module; inserts feature identification codes into the data through a data pre-shaping module, segments the data domain, defines the data flow path, screens out valid data segments, and outputs basic data packets to be routed and forwarded; after the basic data packet flows to the data analysis path module, the data path is decoded, and this module outputs the flow path of the data flow to the destination; the data composition analysis module performs detailed signal-level disassembly of the data to form signal-level to-be-sent data packets; each to-be-sent data packet flows to a data load analysis module; the data load analysis module performs a comprehensive assessment of the data size; and then determines the data forwarding transmission rules, which usually adopt two modes: disassembly of multi-packet loading and transmission, and single-packet direct loading and transmission; when the to-be-sent data packet flows to the sender's mailbox, the time monitoring module performs priority analysis, transmission duration estimation, and maximum delay tolerance estimation on each data packet, and finally forms a sending queue sequence list; and the data sending module sends the data in sequence.
