Abstract: In order to efficiently manage the controller area network (CAN) data of vehicle system, based on the research of CAN network data structure and the accumulation of experience in the development and testing of on-board embedded software, a method of CAN network database management platform based on Python is proposed to realize the import, data editing, data automatic verification, data automatic comparison and CAN network database file output of various formats. It solves the defects of low editing efficiency of the current mainstream CAN network database management tools and the error prone to manual verification and comparison of data, and effectively improves the efficiency of CAN network development and CAN network node controller software development.
