Numerical control system architecture based on four-core processor and construction method

The invention discloses a four-core processor-based numerical control system architecture and a construction method, and relates to the technical field of numerical control, in particular to the technical field of design of a multi-core numerical control system architecture. The method comprises the following steps: firstly, preempting a patch in real time by adopting RT Preempt to enable a bottom-layer Linux operating system to be in real time; the method comprises the following steps: firstly, establishing a user mode component model and a component communication model in a user space of a real-time Linux system, then establishing a unified user mode component model and a component communication model in the user space of the real-time Linux system, and finally establishing a numerical control system architecture model of a four-core processor based on the user mode component model. A domestic CPU and an open-source real-time operating system are adopted, so that the autonomy and controllability of software
