Autonomous controllable numerical control system construction method based on domestic CPU

Abstract

The invention discloses an autonomous controllable numerical control system construction method based on a domestic CPU, and relates to the technical field of numerical control, in particular to the technical field of numerical control systems based on domestic CPUs, in particular to an autonomous controllable numerical control system method based on domestic CPUs. The method comprises the following steps: firstly, constructing an open-source real-time operating system based on a domestic CPU; secondly, establishing a brand-new numerical control system architecture model by adopting an optimization design method of the numerical control system architecture; and finally, designing a network real-time optimization design method of the real-time Ethernet field bus. The research and development cost is reduced, and the research and development period is shortened. An expensive commercial real-time operating system customized abroad is adopted as a bottom-layer operating system of an existing numerical control system. The core control chip also adopts a foreign processor, and the architecture is closed and needs to be authorized. The numerical control system adopts an autonomous and controllable domestic processor chip and an open source operating system, so that the research and development cost can be effectively reduced, and the research and development period is shortened.

AI Technical Summary

Problems solved by technology

The underlying operating system of the domestic high-end CNC system adopts an expensive commercial real-time operating system customized abroad. The system functions are fixed and cannot be optimized for multi-core processors. The core control chip also uses foreign processors, which has a closed structure and requires authorization.

[0003] At present, domestic CPUs have some applications in low-end CNC systems, but have not been applied in high-end CNC systems.
