Problems solved by technology

However, these conversion methods are often only applicable to a single database with a fixed database structure arrangement to convert to DBC. In the face of databases with different layout structures created by different organizations, the algorithm adaptability is poor, which increases the need for database structure adjustment and even database architecture adjustment. workload and risks, and the reusability of the algorithm is poor

Embodiment Construction

[0017] Based on the drawings and examples, the implementation method of the present invention is further described, but not limiting the present invention. The specific implementation method is as follows:

[0018] 1. Design and production of CAN communication database with typical architecture type

[0019] In order to meet the purpose of adaptively converting databases with different layout structures and structures created by different organizations into DBC parsing files, and to make the algorithm more general and reusable. According to the characteristic attributes of CAN communication network and CAN messages: CAN network nodes and CAN message information, a CAN communication database with a more typical architecture type should be designed. Specific steps are as follows:

[0020] Step 1: Extract key features of the CAN communication database

[0021] The key features of CAN message information in the CAN communication database should include (but not limited to the n...

Abstract

The invention relates to the field of CAN communication, in particular to a self-adaptive conversion method and device for converting a CAN communication matrix database into a DBC file. According tothe self-adaptive database conversion method and device, the method comprises the following steps: (1) reading a target communication matrix database file; (2) identifying a target communication matrix database architecture; (3) remodeling a target communication matrix database; and (4) analyzing the database information and generating a corresponding standard DBC file. The device is system software which is based on computer programming, combines technologies of multi-target recognition, architecture recognition, architecture remodeling and the like, and realizes adaptive conversion of CAN communication databases with different architectures. The method has the characteristics of good architecture adaptability, friendly GUI interface, simple operation, high conversion quality and efficiency and the like. Compared with the prior art, the method has the advantages that manual modification or adjustment of CAN communication database information is reduced as much as possible, manual editing errors are avoided to the maximum extent, the DBC manufacturing time is greatly saved, the DBC manufacturing efficiency is better improved, and the professional labor cost is reduced.

Description

technical field [0001] The invention relates to the field of CAN communication, in particular to an adaptive conversion method and device for converting a CAN communication matrix database into a DBC file. [0002] technical background [0003] The DBC file of the CAN communication network system is an important communication analysis file, which is often used in the development, debugging and verification of communication systems such as computer networks, automotive communications, ships, rail transit, aerospace, Internet of Vehicles, and Internet of Things. For example: "A Method for Converting an Excel File to an Automotive Network DBC File", the application number is 2017105405671; and "A Data Conversion Method and Device", the application number is 2018104193092 Chinese invention patents. Both disclose a method for converting and generating a DBC file by reading an Excel or spreadsheet file and parsing the obtained communication matrix data information. It does not nee...
