Embodiment Construction

[0053] The embodiment of the present invention solves the technical problem of low efficiency of manually constructing CAN communication modules in the prior art by providing a method and system for rapidly creating CAN communication modules.

[0054] In order to better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0055] First of all, the term "and / or" that appears in this article is just an association relationship that describes associated objects, which means that there can be three relationships, for example, A and / or B, which can mean: there is A alone, and A exists at the same time and B, there are three cases of B alone. In addition, the character " / " in this article generally indicates that the contextual objects are an "or" relationship.

[0056] like figure 1 As shown, the rapid creation method of...

Abstract

The invention discloses a rapid creation method and system of a CAN communication module, and relates to the technical field of CAN communication. The method comprises the steps of firstly, acquiring a CAN communication matrix of a hydrogen fuel cell system, then generating a basic information table according to the CAN communication matrix, then defining a CAN receiving configuration function, a CAN sending configuration function, a CAN interrupt receiving processing function, a CAN coding function and a CAN decoding function according to the basic information table, generating code text files of all the functions, completing definition and processing of a CAN receiving configuration module, a CAN sending configuration module, a CAN interrupt receiving processing module, a CAN coding module and a CAN decoding module, finally, combining the code text files of all the functions, and generating a source file of the CAN communication module. Rapid creation of the CAN communication module controlled by the hydrogen fuel cell system is achieved, the creation efficiency of the CAN communication module is improved, and the workload is reduced.

Description

technical field [0001] The invention relates to the technical field of CAN communication, in particular to a method and system for quickly creating a CAN communication module. Background technique [0002] Many key components of the hydrogen fuel cell system are coordinated and controlled through the CAN (Controller Area Network, Controller Area Network) communication network. The advantages of the hydrogen fuel cell system and the achievement of key performance indicators are inseparable from the control function of the hydrogen fuel cell controller. The control of the hydrogen fuel cell controller is completed by three parts: the upper layer application control, the lower layer drive control, and the upper layer and lower layer integration, that is, the software and hardware integration control of the control system. The control of the hydrogen fuel cell system is to transmit the message signal through the CAN communication module, and complete the scheduling of the upper...
