Abstract

The invention provides a general communication protocol conversion method based on a numerical control system. The method reads the rule information in the communication conversion rule database and calls the communication interface of a specific type of numerical control system to realize the data obtained from the communication interfaces of different numerical control systems. Carry out protocol format conversion and interface mapping, and convert them into OPC UA communication nodes in a unified manner, so as to realize the data interaction between the numerical control equipment data and the client system and the upper layer of the industrial network. The present invention can convert different numerical control communication protocols into a common OPC UA communication protocol, which is flexible in application, can not only directly serve end users, but also provide direct technical support for the development of upper software and hardware systems of the Industrial Internet of Things, and strengthen the system integration ability , which speeds up the development efficiency and is conducive to system maintenance, improvement and subsequent function expansion.

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...
