Problems solved by technology

It can be seen that every time a DBC file is generated, it not only takes a lot of time to create message frames and signals, but also increases the error rate of generating DBC files
Therefore, the current method of generating DBC files is extremely dependent on manual operation, and the operation process is complicated, and the generation quality and generation efficiency are not high.

Embodiment Construction

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0043] Each DBC file includes a plurality of message frames, and each message frame includes a plurality of signals. At present, the way to generate DBC files is usually to use the common editing software of DBC. The specific process is: first create multiple message frames in sequence, for example, create a new message frame, and then set it according to the definition of the message frame in the communication matrix. Complete the creation of a messag...

Abstract

The embodiment of the invention provides a method and device for generating a DBC file, and the method comprises the steps: loading a preset script and obtaining predefined information which comprises signal information and message frame information corresponding to the signal information, writing the predefined information into an array of the preset script through the preset script, when the output requirement of the DBC file is detected, extracting the predefined information from the array through a preset script, and outputting the signal information and the corresponding message frame information as the DBC file. According to the embodiment of the invention, the signal information and the message frame information in the table file are output at one time through the preset script to obtain the DBC file, so that the time for generating the DBC file is greatly saved, the error rate of generating the DBC file is reduced, and the generation quality and the generation efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to a method and device for generating a database DBC file. Background technique [0002] CAN (Controller Area Network, Controller Area Network) is an ISO international standardized serial communication protocol, which is widely used in the current vehicle industry. [0003] DBC (Database Can) is the database file of CAN. Through the DBC file, the CAN communication information can be completely and clearly defined, so that the communication of the CAN network can be carried out according to the description of the DBC file. [0004] When using commonly used editing software to generate DBC files, it is necessary to manually create and define each message frame and corresponding multiple signals online sequentially. It can be seen that every time a DBC file is generated, it not only takes a lot of time to create message frames and signals, but also increases the error rate o...
