Numerical control system code automatic generation method based on field modeling

Abstract

The invention discloses a numerical control system (NCS) code automatic generation method based on domain modeling (DM). The method comprises the following steps that: firstly, according to the system concept and logic in the numerical control field, an element model in the numerical control field is set up; then, a system application model is set up according to the requirements of a NCS; secondly, the application model is directly converted into system source code through a model interpreter, thereby realizing model-centered automatic development process; thirdly, according to the three modules (i.e. man-machine interface, PLC and motion control module) of the NCS, element models are respectively set up; fourthly, based on the element models, the modeling environment of the application model is set up. According to the types of an object platform and programming language, an object software frame is established and a mapping rule database from the model to software source code is set up; therefore, a modeler can complete quick reconfiguration of system functions from model hierarchy and realizes automatic generation of source code and relevant configuration files. The development method and relevant supporting tools can effectively shorten the development cycle of the NCS and increases development efficiency.

Description

technical field [0001] The fields involved in the present invention include domain-oriented modeling, embedded numerical control development and automatic generation of source codes, in particular an automatic development method and related tool chains for automatically generating numerical control system source codes based on numerical control domain-oriented models. Background technique [0002] Cost, quality, and responsiveness to market demand are the three pillars of a manufacturing enterprise. Modern computerized numerical control (Computerized Numeric Control CNC) system and related technologies are the cornerstone of manufacturing industry. High reliability and high cost performance are important development trends of today's embedded numerical control system. The embedded software system is closely related to a specific hardware environment, and in most cases must complete strictly prescribed tasks, which makes it very different from the software system running on t...

Problems solved by technology

At present, the development of embedded CNC systems mostly adopts the process-based development method of strong coupling centered on the program code, resulting in poor system maintainability, slow technological improvement, unpredictable development cycle, and unable to keep up with changes in market demand.
