The application discloses a full life cycle management method of an intelligent hanger based on a PLM system, relates to the technical field of intelligent manufacturing and PLM, and comprises the following steps: a digital master model integrated with a three-dimensional model, a material list and process rules is established in a PLM system; a standardized two-way data interface with a production execution system and a workshop Internet of Things is constructed to acquire state data flow in the process of hanger manufacturing, use and maintenance in real time; based on real-time data and preset rules, the system dynamically evaluates the suitability of the hanger, generates process recommendations or risk warning instructions, and issues the instructions to a production system; and the digital master model is synchronously updated according to the state data to form an evolution model mapping the real state of the entity. The method realizes real-time linkage between the state of the hanger and the design model, improves the precision of process adaptation and the risk control capability, and provides a dynamic data basis for the full life cycle optimization of assets.

This application relates to the field of data processing technology, and in particular to a data maintenance method, apparatus, digital master platform, and computer equipment. The method, applied to a digital master platform, includes: acquiring domain knowledge for each stage of the global process and determining the metadata definition of each element within that domain knowledge; extracting attribute information of components at each level and relationship information between components from the application model corresponding to each stage; aligning the metadata definition with the relationship and attribute information for each stage to obtain standard relationship and attribute information for the target dimension; constructing a component database based on the standard relationship and attribute information; and constructing a central semantic model based on the component database corresponding to each stage. The central semantic model is used for data mapping of components to the application model corresponding to each stage. The solution adopted in this application can improve the efficiency of iteration between stages.

This document describes a method and apparatus for testing and / or manufacturing holograms. Specifically, a method for manufacturing and / or testing holograms on a planar or substantially planar substrate or on a cylindrical roller is provided, the method comprising the steps of: generating a target holographic optical element (HOE) based on input geometric parameters and input system parameters; generating a digital master printer control file and test pass / fail criteria; printing a master hologram; testing the master hologram, and if the master hologram passes the test criteria: generating a first witness replica from the master hologram; testing the replica hologram, and if the replica hologram passes the test criteria: mass-producing replica copies on a curved substrate using the master and / or replica holograms.
