In a smart factory environment, a much larger amount of data are transmitted in the workshop networks bringing big challenges to data transfer capability and energy usage efficiency. In the workshop, two main networks, i.e., wired/wireless fieldbus networks and wireless sensor networks, are usually used to collect and transmit data separately; thus, this paper proposes a mobile and hierarchical data transmission architecture to integrate these two networks also taking advantages from the existing mobile intelligence in smart factories, such as automatic guided vehicles (AGVs), to implement a novel data and materials delivery scheme well suited for modern industrial wireless sensor networks (IWSNs). Simulation experiments demonstrated how the proposed approach, running within the IWSN, significantly increases data delivery efficiency along with achieving better energy usage, by 4 times, with respect to the separated networks without any mobile intelligence support.

用于智能工厂的新型移动和分层数据传输体系结构

在智能工厂环境中，车间网络中会传输大量数据，这给数据传输能力和能源利用效率带来了巨大挑战。在车间中，通常使用两个主要网络，即有线/无线现场总线网络和无线传感器网络，分别收集和传输数据。因此，本文提出了一种移动和分层的数据传输架构，以结合这两个网络，同时也利用智能工厂中现有的移动智能（例如自动导引车（AGV））的优势，实现一种非常适合于现代工业无线传感器网络（IWSN）。仿真实验证明了该建议方法如何在IWSN中运行，
