Problems solved by technology

[0003] However, with the increase in the amount of monitoring data, the complexity of managing and accessing large data sets has become a prominent problem faced by both data producers and users. Data producers need effective ways to organize, manage and maintain massive data
At the same time, according to different production types and production lines, the generated data is heterogeneous, and it is difficult to manage data of different branches and types and query characteristic data

Embodiment Construction

[0016] In order to make the purpose of the present invention, technical solutions and advantages clearer, the present invention will be described in further detail below in conjunction with accompanying drawing:

[0017] The present invention proposes a method for unified management of different production lines based on metadata, the method comprising the following steps:

[0018] Establish a unified data model based on the data in the database, where the content of the data model includes objects in the business system, object attributes, and relationships between objects, and produce basic metadata types such as figure 1 As shown, for the metadata of the general production line management system, the basic rules should follow the principles of simplicity and applicability, interoperability and easy conversion, flexibility and scalability, structure and user needs.

[0019] Take the following rule definition:

[0020] (1) Uniqueness rules, metadata definition rules must cla...

Abstract

The invention discloses a method for realizing unified management of different production lines based on metadata. Through the introduction of metadata management, a lot of collected data in a production information management system can be easily accessed, the level of management is improved, and the complexity of management is reduced. Data in different sites and of different sources is managedin a unified manner by using the web network technology. First, metadata is defined according to service. Then, a database model is established according to the metadata. The data is mapped to the database based on data description, and unified management of heterogeneous data sources is realized. Through the web network technology, unified management of different production lines in different sites is realized.

Description

technical field [0001] The invention belongs to the technical field of manufacturing informatization, and relates to a unified management method for realizing different production lines based on metadata. Background technique [0002] To be more competitive in today's industrial automation world, manufacturing companies need to simultaneously reduce time to market, increase process visibility and production flexibility, optimize forecasting and scheduling, and reduce scrap rates, inventory levels, and downtime; while ensuring that all global facilities best quality and productivity. Therefore, in order to meet these high demands, manufacturing companies need an integrated IT infrastructure that helps them coordinate production globally and, if necessary, in real time. A Manufacturing Execution System (MES) is often referred to as the IT layer that integrates business systems such as ERP (Enterprise Resource Planning) and production control systems. [0003] However, with t...
