CAN interactive layer code automatic generation method and system

Abstract

The invention relates to a CAN interactive layer code automatic generation method and system. The method comprises the steps of obtaining a pre-defined data type and a pre-written CAN database file; determining message frames comprised in the CAN database file and a quantity of the message frames; calling CAN_Pack modules with the same quantity as the message frames, processing signals of bytes inthe message frames through the CAN_Pack modules, and storing the signals in a preset folder according to data types; processing and packaging the CAN_Pack modules to obtain atomic sub-models of the CAN Pack modules; and calling signal automatic generation codes in the preset folder through all the atomic sub-models. According to the CAN interactive layer code automatic generation method and system provided by the invention, the waste of manpower resources and material resources is avoided; the workload of development personnel is reduced; the development efficiency is improved; and the errorrate in the development process is reduced.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method and system for automatically generating CAN interaction layer codes. Background technique [0002] In the pure electric vehicle control system, BMS (Battery Management System, battery management system) and other controllers mostly use CAN (Controller Area Network, controller area network) to communicate, and the information in the CAN network needs to pass Only by analyzing the CAN communication protocol can the signal with actual physical meaning be obtained. In practical applications, the CAN communication protocol is often defined as the format of the CAN database file, and the BMS software is usually developed by handwriting codes. [0003] However, the BMS interacts with other controllers with more information, which can easily cause a large number of semaphores in the CAN database file, and it is easy to make mistakes during the development of handwritten C codes. ...

AI Technical Summary

Problems solved by technology

[0003] However, the BMS interacts with other controllers for more information, which can easily cause a large number of semaphores in the CAN database file, and it is easy to make mistakes in the development process of handwritten C codes.

With the increase of CAN database files, the development difficulty and workload of CAN interactive layer software will increase, resulting in a longer development cycle

At the same time, during the development process, the CAN communication protocol and CAN database files need to be revised repeatedly, resulting in waste of manpower and material resources and low development efficiency
