Abstract

A vibration sensor based on the use of a Software-Defined Radio (SDR) platform is adopted in this work to provide a contactless and multipurpose solution for low-cost real-time vibrations monitoring. In order to test the vibration detection ability of the proposed non-contact method, a 1 GHz Doppler radar sensor is simulated and successfully assessed on targets at various distances, with various oscillation frequencies and amplitudes. Furthermore, an SDR Doppler platform is practically realized, and preliminary experimental validations on a device able to produce a harmonic motion are illustrated to prove the effectiveness of the proposed approach.

摘要

本研究采用基于软件定义无线电（SDR）平台的振动传感器，为低成本实时振动监测提供非接触式多功能解决方案。为测试所提出的非接触方法的振动检测能力，对1 GHz多普勒雷达传感器进行了模拟，并在不同距离、不同振荡频率和幅度的目标上成功进行了评估。此外，实际实现了一个SDR多普勒平台，并展示了对能够产生谐波运动的设备进行的初步实验验证，以证明所提方法的有效性。
