    • 摘要: 在工业4.0的智能制造以及工业5.0的人本主义理念推动下,离散制造业对于利用生产过程中人、机、物的精准时空信息以提升车间物流管理水平的需求日益迫切。然而,如何在车间复杂的环境中实时准确地定位生产资源,以及如何运用时空数据提供智能服务以实现物流运营的降本增效,是企业面临的主要挑战。本文分析了离散制造车间物流管控的实际需求与时空数据的潜在作用,提出了一种由室内定位技术驱动的车间物流智能管控系统框架,结合工业物联网、云计算、数字孪生、人工智能等技术,为物流运营中的各类人员提供基于位置的智能服务。提出了一种面向车间复杂环境的细胞识别室内定位算法,融合蓝牙低功耗和超宽带无线技术,感知环境变化并进行在线自适应更新,实现了高精度、高稳定性的实时定位,同时整体方案具有成本低、易于部署、扩展性强等优点。最后,在某电脑制造商的主机生产车间,对所提出的车间物流智能管控系统框架和细胞识别室内定位算法进行了原型系统的开发和应用验证。

       

      Abstract: Under the impetus of smart manufacturing in Industry 4.0 and the human-centric ideology of Industry 5.0, there is an increasingly urgent demand in the discrete manufacturing industry to utilize precise spatial-temporal information of people, machines, and materials in the production process to enhance workshop logistics management. However, how to accurately locate production resources in real-time within the complex workshop environment, and how to use spatial-temporal data to enable intelligent services in logistics operations for cost reduction and efficiency improvement, pose significant challenges for enterprises. After analyzing the requirements of logistics management and control in discrete manufacturing and the potential role of spatial-temporal data, a framework of intelligent control system for workshop logistics driven by indoor positioning technology is proposed. This framework combines Industrial Internet of Things (IIoT), cloud computing, digital twin (DT) and artificial intelligence (AI) technologies to provide location-based intelligent services for various personnel in logistics operations. In response to the complicated workshop environment, a Cell Recognization Indoor Localization Algorithm (CRILA) that integrates Bluetooth Low Energy (BLE) and Ultra-Wideband (UWB) technologies is proposed, which can sense environmental changes and adapt on its own online, thus achieving timely high-precision and high-stability positioning. The overall scheme also has the advantages of low cost, easy deployment, and strong scalability. Finally, the proposed system framework and algorithm were developed and validated in the mainframe production workshop of a computer manufacturer.
