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工业适用的低功耗传感器节点，用于机床中快速旋转金属工具的过程监测。数据的阅读和无电池传感器节点的电力供应将无线地进行。在24 GHz的反向散射调制用于无线电通信。电力是通过太阳能电池的光电效应提供的。机床内的应用领域（油、冷却液）导致无线电信道困难，并在光学电源和与刀具保持器的行业标准集成方面带来重大挑战。该项目以合作研究中心次级项目L2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.
