Low power sensor node with photovoltaic power supply for wireless-based monitoring of thread cutting and thread inspection processes (T08#)

本项目的目的是开发一种适合于工业的低功耗传感器节点，用于机床中快速旋转的金属刀具的过程监控。无电池传感器节点的数据读取和电源供应将以无线方式进行。无线电通信采用24 GHz的后向散射调制。电力是通过太阳能电池提供的光伏。机床(机油、冷却液)的应用领域导致无线电频道困难，在光学电源和与刀架的行业标准集成方面也面临重大挑战。该项目以协作研究中心L2子项目的研究成果为基础。

The aim of this project is the development of an industrial-suited low power sensor node for process monitoring of fast rotating metal tools in machine tools. The reading of the data and the power supply of the battery-less sensor node is to take place wirelessly. Backscatter modulation at 24 GHz is used for the radio communication. Power is supplied photovoltaic by means of solar cells. The field of application within the machine tool (oil, coolant) results in a difficult radio channel and in major challenges in the optical power supply and the industry-standard integration into the tool holder. The project builds on research results of the subproject L2 in the Collaborative Research Centre.
