C++ code generation method for unmanned aerial vehicle flight mode based on state machine diagram

Abstract

The invention provides a C++ code generation method of an unmanned aerial vehicle flight mode based on a state machine diagram, for solving the problems of low efficiency of generating an unmanned aerial vehicle code and insufficient quality of the generated code due to the fact that a code generation method in the prior art is not attached to an unmanned aerial vehicle platform and lacks a code conversion method. The C++ code generation method comprises the following steps: formulating a work flow of each flight mode of the unmanned aerial vehicle flight control system; constructing a framework SysML state machine diagram of the unmanned aerial vehicle; constructing a sub SysML state machine diagram of the flight mode mi based on the framework SysML state machine diagram; obtaining an XMIfile of each flight mode mi; formulating a hierarchical code generation rule; and based on the hierarchical code generation rule, obtaining a C++ code of the unmanned aerial vehicle flight control system.

Description

technical field [0001] The invention relates to the field of software development, in particular to a C++ code generation method for embedded system software based on a SysML state machine diagram. Background technique [0002] Embedded systems are application-centric, based on modern computer technology, and can flexibly tailor software and hardware modules according to user needs, functions, reliability, cost, volume, power consumption, and environment. Due to limited storage space, The software code is required to be compact, reliable, and have strict requirements on real-time performance. At present, there are many types of languages ​​used in the development of embedded systems, but only a few languages ​​have been widely used, mainly Ada, C / C++, etc. Because the C++ language not only has the efficiency of assembly language, but also has the ease of programming of high-level language, it is currently the most widely used embedded system programming language. An excell...
