The staff convenient manufacturing system based on the compiling technology has two major key points. Firstly, emphasizing that the user experience is improved by constructing a system front end with a convenient interaction function, and converting a user instruction into an intermediate language; second, it is important to highlight the translation of the intermediate language into midi format output by the compilation technique. The system for generating the midi-format file by the user instruction is finally obtained through the collection of the instruction, the generation of the intermediate language and the lexical analysis, the syntactic analysis and the semantic analysis in the compiling process. The collection of the instructions refers to collecting the instructions input by the user by the graphical interface, such as requirements on pitch, volume, duration and the like. The generation of the intermediate language means that the obtained commands are arranged to obtain a required data form. The compiling module comprises three parts of lexical analysis, syntactic analysis and semantic analysis, and translates the intermediate language into a midi format file as output.
The technical scheme of the invention can adopt a computer software technology to realize modular design. The technical scheme of the invention is explained in detail in the following by combining the drawings and the embodiment.
