Embodiment Construction
[0028] The modeling development method of the computer numerical control system based on the real-time layered finite state machine of the present invention includes two layers of domain layer and implementation layer. The domain layer includes computer numerical control system meta-modeling and user modeling, and the implementation layer includes the functional and non-functional verification of the model and the automatic generation of the source code of the model. as attached figure 1 As shown, GME meta-modeling software 101 is used to construct a computer numerical control system meta-model 103 based on real-time layered finite state machine theory 102 . After the meta-model has undergone attribute configuration and OCL language specification, the built-in meta-model interpreter 104 of GME generates a computer numerical control system modeling language 105, which has a visual modeling environment. The numerical control system user 106 can use the modification model enviro...

Description
technical field [0001] The invention relates to the field of computer numerical control systems, in particular to a modeling development method for computer numerical control systems. Background technique [0002] Computer numerical control system is a typical hybrid real-time system, which is a mechatronics product of multi-disciplinary (mechanical / electromechanical, automation, electronics, computer) cross-integration, and has the characteristics of diverse control system platforms and diverse control objects. The traditional development method adopts the spiral rising method of "parallel development of software and hardware by engineers from different disciplines->integration test->development optimization and re-testing". Low performance, difficult to guarantee real-time performance and other issues. So far, with the maturity of high-performance components such as linear motors, electric spindles, sensors, servo controls, and frequency converters and the breakthro...
