Title:
METHOD AND DEVICE FOR IMPLEMENTING VIBRATION MONITORING
Document Type and Number:
WIPO Patent Application WO/2016/184226
Kind Code:
A1
Abstract:
A method and device for implementing vibration monitoring. The method comprises: generating a nonlinear center wavelength signal associated with vibration change by means of a reflection spectrum (100); converting the generated nonlinear center wavelength signal into corresponding vibration information to implement vibration monitoring (101); and further giving a vibration alarm by means of a preset alarm frequency. The method and the device utilize the characteristics of an optical signal and monitor vibration information by means of the optical signal, thereby improving anti-interference capability of vibration monitoring; a vibration frequency is calculated according to a wavelength, such that the accuracy of the vibration information is improved; and stability is also improved, reference information is provided for guaranteeing network security, and property loss caused by delayed obtaining of the vibration information is avoided.
