Embodiment Construction
[0024] The CNC development method of the present invention includes several steps of meta-modeling, user modeling, model verification and code generation. Figure 1 is a schematic diagram of the CNC system modeling and development process. The CNC development method based on domain-specific modeling includes four processes, meta-modeling, application modeling, model verification, and code generation. In the metamodel modeling environment 101, the CNC metamodel 102 is established, which is interpreted into the CNC modeling language by the metamodel interpreter 103, that is, the computer numerical control field modeling environment 104, and the application model 105 is established in the modeling environment, through model interpretation The controller 106 generates the source code 107 under the corresponding hardware platform, and compiles and generates the numerical control system 108 .
[0025] Specific steps are as follows:
[0026] (1) Meta-modeling

The invention discloses a modeling method in the computer numerical control field, comprising the following steps: firstly, a field space is parted by adoption of a multi-view means; secondly, field characteristics are captured and mapped to corresponding multi-view planes; thirdly, element modeling is performed in corresponding view containers according to the characteristics; fourthly, an element model of the field generates a computer numerical control field oriented modeling language through an element model interpreter; fifthly, an applied model is established by the multi-view means according to the modeling language; sixthly, functional and nonfunctional attributes of the applied model are verified through model verification; seventhly, automatic generation of source codes under a platform is realized through the model interpreter. The invention establishes a modeling environment aiming at the computer numerical control field, and can realize functional and nonfunctional verification in model level and realize automatic generation of the codes; moreover, reliability and development efficiency of a numerical control system can be improved, and nonfunctional attributes like real-time performance and so on of the numerical control system can be guaranteed.
Description
technical field [0001] The invention relates to the field of computer numerical control, in particular to a modeling method in the field of computer numerical control. Background technique [0002] The computer numerical control system involves multiple disciplines such as electromechanical, electronics, software and control. The traditional development method is to develop the software and hardware of a single application system separately. This development method generally has problems such as low reusability, low development efficiency, non-functional attributes cannot be guaranteed, and system integration testing is difficult. [0003] Software reuse is considered to be an effective way to solve the software crisis. Due to the characteristics of cohesion and stability in a specific field, the application of software reuse in a specific field is more likely to succeed. In the field of software engineering, component-based software engineering and domain engineering have ...
