一种制造过程多模态数据因果链构建系统及方法

本发明涉及一种制造过程多模态数据因果链构建系统及方法，属于数字化制造技术领域。该方法是通过物联网、多源异构信息系统集成手段，实时感知信息多模态识别技术，采用电子标签唯一标识出产品，以产品为核心，建立覆盖计划、生产、交付过程的数据模型，将制造过程中的多种模式、多种状态下的数据(包括生产现场产品、物料、设备、环境等对象的多维度信息)关联起来，综合形成制造过程数据的因果链，形成融合生产线各类数据、衔接感知、决策、仿真、控制、执行的数据基础，从而为产品制造过程数据的追溯、技术状态闭环管理提供有效支持。 The invention relates to a manufacturing process multi-modal data causal chain construction system and method, and belongs to the technical field of digital manufacturing. According to the method, through an internet of things and multi-source heterogeneous information system integration means, and a real-time perception information multi-modal identification technology, a product is uniquely identified by an electronic tag, the product is centered, and a data model covering a plan, the production and the delivery process is established; data (including multi-dimensional information of objectssuch as production field products, materials, equipment and environments) in various modes and various states in the manufacturing process are associated; and a causal chain
