Wireless sensor based real-time data acquisition and state analysis in a machining system

该项目旨在开发一种基于无线传感器的实时数据采集和机床状态分析系统，该系统将与铣床集成，以提高工件的质量。预计将实现以下成果：(I)研究以适当的无线传感器替代目前使用的基于有线加速度计的振动传感设备；(Ii)在安装了带有接收模块微控制器和信号处理单元的监测设备的附近房间中对来自传感器发射器的接收信号进行表征；以及(Iii)开发多传感器数据融合方法以确定机床的状态。在铣床和车床上使用无线传感和监控系统，有望帮助提高效率和可靠性，减少加工产品的浪费，提高制造业的质量。

This ENGAGE project aims to develop a wireless sensor based real-time data acquisition and machine state analysis system that will be integrated with milling machines to improve the quality of the work-pieces. The following are expected to be achieved (i) investigation of appropriate wireless sensor replacement for currently used wired accelerometer-based vibration sensing device, (ii) characterization of the received signals from the sensor transmitter at a nearby room where the monitoring device, with receiver module microcontroller and signal processing units, is installed, and (iii) development of multi-sensor data fusion methodology to determine the state of the machine tool. The use of wireless sensing and monitoring system in milling and turning machines is expected to help improve the efficiency and reliability with less wastage of milled products and improved quality in manufacturing industry.
