Description

Technical Field

[0001] The present invention relates to the technical field of vehicle-domain communication and vehicle-cloud communication, and in particular to a DBC service processing method, device, electronic device and storage medium. Background Art

[0002] SOA (Service Oriented Architecture) is a software architecture design method. The architecture design includes multiple services, which provide a series of functions through mutual dependence. Each service usually exists in an independent form in the operating system process, and each service is called through the network.

[0003] DBC files are CAN (Controller Area Network) database files, which are usually used to describe messages and signals in the network. These files are used to describe the communication protocol between ECUs (Electronic Control Units) on the CAN network, including the format of messages, signal properties, data types, ranges, etc.

[0004] The existing DBC parsing implementation solution is to convert the DBC file into static code and compile it together with the business program and import it into the ECU system. At the same time, after receiving the CAN message in the business process, the signal value in the DBC database is updated in real time, and logical processing is performed according to the signal value in the business process based on the parsed value. This can meet the needs in the traditional centralized development model, but it is not advantageous for the development of SOA software architecture.

[0005] In the SOA architecture, each service may communicate across ECUs, across the entire vehicle domain, or even across the vehicle-cloud. How can so many microservices achieve dependence on DBC services? The original in-process parsing and processing method cannot meet this business requirement. Summary of the invention

[0006] In order to solve the deficiencies of the prior art, the present invention provides a DBC service processing method, device, electronic device and storage medium, which fully utilizes the characteristics of each business in the SOA architecture as an independent process program, converts the DBC file into static code and compiles it into a library file. There can be multiple library files in the system, that is, dynamic library files generated by multiple different DBC files. The DBC service selects to load the corresponding dynamic library file by reading the vehicle model configuration file, and the status broadcast is performed only when the signal value is updated, and remote real-time query is supported.

[0013] Step a1, after the DBC service module loads the library file, an index relationship is established between the signal name and the signal index ID of each signal, and an association list is generated;

[0014] Step a2: The DBC service module receives the vehicle CAN data and / or CANFD data in real time, performs data analysis, and updates the local signal value in real time;

[0015] Step a3: other business service modules call to obtain the association list generated in step a1, obtain the latest signal value through the signal index ID, and perform corresponding business processing.

[0016] In an optional embodiment, obtaining a signal index ID and a signal value by subscribing to a broadcast, and performing service processing according to the signal index ID and the signal value includes the following process:

[0018] Step b2: The DBC service module receives the vehicle CAN data and / or CANFD data in real time, performs data analysis, and updates the local signal value in real time;

[0019] Step b3: other business service modules call to obtain the association list generated in step b1, and obtain the signal value of the latest state through the signal index ID;

[0020] Step b4, other business service modules subscribe to DBC services;

[0021] Step b5: When the DBC service module detects that the signal value is updated, it actively broadcasts the signal ID and signal value to the corresponding subscriber;

[0022] Step b6: Other business service modules subscribing to the DBC service obtain the update information of the signal index ID and the signal value, and then perform corresponding business processing.

[0023] In a second aspect, an embodiment of the present invention further provides a DBC service processing device based on an automobile SOA architecture, the device comprising:

[0024] A compilation module is used to convert each DBC file into static code and compile the static code into a library file;

[0025] DBC service module, used to read vehicle configuration files, load the library files of the corresponding vehicle according to the vehicle configuration files, and obtain the signal index ID and signal value by actively querying or subscribing to broadcasts;

[0026] The business process module is used to perform logical processing based on the signal index ID and signal value.

[0027] In a third aspect, an embodiment of the present invention further provides an electronic device, comprising a processor and a memory, wherein the memory is coupled to the processor, and the memory stores instructions, which, when executed by the processor, enable the electronic device to perform the steps of any one of the aforementioned methods.
