Programming method of numerical control system

Abstract

The invention discloses a programming method of a numerical control system. The programming method comprises the following steps: micropython codes are written in the user state; the micropython codeswritten in the user state are packed in the non-compression mode by using the zip format; the micropython codes are transmitted to a data buffer area in the kernel mode through an I / O interface; theCPU of the numerical control system receives a timing interrupt signal and then calls the micropython codes stored in the data buffer area. According to the programming method of the numerical controlsystem, the programming of the numerical control system can be simplified, and the operation efficiency of the numerical control system is improved.

Description

Technical field [0001] The present invention relates to the field of communication, and in particular to a programming method of a numerical control system. Background technique [0002] Numerical control systems are increasingly used in modern industrial control. Common industrial controllers, such as programmable logic controllers (Programmable Logic Controller, PLC), mostly use embedded hardware platforms such as single-chip microcomputers or RAM, and usually use special instructions or ladder diagrams for programming, and use ladder diagrams to implement logic. Although it is intuitive and easy for on-site personnel to operate, the language is poor in expressiveness, and there are no very intuitive comments and variable names, and the maintenance is poor. In addition, the PLC registers of various manufacturers are different, and the symbols and programming rules of the ladder diagram of the PLC products of different manufacturers are inconsistent, resulting in poor program p...

Common industrial controllers, such as programmable logic controllers (Programmable Logic Controller, PLC), mostly use embedded hardware platforms such as single-chip microcomputers or RAMs, and usually use special instructions or ladder diagrams for programming, and use ladder diagrams to implement logic. Although it is intuitive and easy to operate by on-site personnel, the expressiveness of the language is poor, and there are no intuitive comments and variable names, so the maintainability is poor

In addition, the PLC registers of various manufacturers are not the same, and the symbols and programming rules of the ladder diagrams of PLC products of different manufacturers are inconsistent, resulting in poor program portability, poor compatibility, and poor reproducibility
