Abstract

The invention provides a universal communication protocol conversion method based on a numerical control system. According to the method, rule information in a communication conversion rule database is read; a communication interface of a numerical control system of a specific model is called, protocol format conversion and interface mapping are carried out on data obtained by communication interfaces of different numerical control systems, the data are converted into OPC UA communication nodes in a unified mode, and data interaction between numerical control equipment data and a client systemand an industrial network upper layer is achieved. According to the invention, different numerical control communication protocols can be converted into a universal OPC UA communication protocol; thesystem is simple in structure and flexible in application, not only can directly serve terminal users, but also can provide direct technical support for development of upper software and hardware systems of the industrial Internet of Things, enhances the system integration capability, accelerates the development efficiency, and is beneficial to system maintenance, improvement and subsequent function extension.

Description

technical field [0001] The present disclosure relates to the technical field of numerical control data communication, in particular to a general communication protocol conversion method based on a numerical control system. Background technique [0002] The data communication of the CNC system in the industrial Internet is the technical basis for automatic data collection and industrial Internet application development. The intercommunication and interconnection of various CNC systems and sensors in industrial networks makes it possible to develop various industrial Internet applications such as data collection, big data analysis, and edge computing. [0003] At present, the communication protocols and software interfaces adopted by major mainstream CNC system suppliers have not yet been unified, and the operating environments are incompatible with each other. For example, the network communication interface of HEIDENHAIN CNC products is a DCOM component based on the DNC pro...
