Description

CROSS-REFERENCE TO THE RELATED APPLICATION

This application is based upon and claims priority to Chinese Patent Application No. 202310166624.X filed on Feb. 27, 2023, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present application belongs to the technical field of electrical digital data processing, and in particular relates to a method of interfacing a discrete digital workshop information system.

BACKGROUND

Discrete manufacturing means that a product basically does not change materially during a production process, and only a shape and combination of materials change. That is, the product is assembled from various materials with a certain quantitative ratio between the product and a required material. For example, the quantity components of one product, and the quantity of parts of a component are definitive, and cannot be changed. For example, manufacturing industries such as rockets, airplanes, weapons and equipment, ships, electronic equipment, engineering machinery, machine tools, automobiles and automobile parts, medicine, rail transit, etc. are all discrete manufacturing industries.

In our country, discrete manufacturing enterprises have made rapid progress in product production technology, and have formed a relatively complete production and manufacturing system, which can substantially meet the needs of national economy and national defense construction. However, compared with advanced foreign countries, the overall level of equipment digitalization in a production workshop is generally low, and the problem related to “information islands” in the production workshop is serious. The production process of a small manufacturing enterprise relies more on manual labor. Some large enterprises have only realized digitization of some process sections, but have not achieved full-process automated production and informatization management and control, and thus product quality tracing is difficult. There is a lack of unified definitions of equipment integration data and information system integration data, one-to-one analysis and integration is required for different manufacturers and different models of equipment. In particular, non-uniform equipment lead to single information system function, and a small amount of integrated information, which cannot meet the needs of intelligent development in the discrete manufacturing industry. These problems lead to enterprises being unsuitable for flexible production, uncontrollable production processes, unstable product quality, low production efficiency, and high operating costs.
