Title The optical fiber grating temperature signal
Acquisition and processing software
Abstract
Optical fiber garting temperature measurement system is developed for the real-time measurement of temperature field of space distribution sensor system.In the field of sensors,optical fiber grating temperature sensor using optical fiber grating wavelength variation of measured temperature values.
This paper introduces the optical fiber garting temperature measurement system hardware composion,working principle and signal demodulation method.Focusing on the signal acquision and processing system,using MFC programming system signal aquisision software interface on measurement signal system,using Visual C++6.0 development environment designed fiber bragg grating temperature measurement system signal acquisision, real-time dynamic display system.At the same time,the use of SQL2008as the back-end database,based on ADO data access technology to realize the signal acquisision and storage,historical inquiry and print function.
