【摘要】 为了进一步提高光纤光栅传感器的实用性,本文对光纤光栅传感原理进行理论分析,并将无线收发技术与光纤光栅传感技术相结合。实验通过采用 nRF905无线收发芯片和C8051F020单片机组成无线传输系统,以实现对光电转换和模数转换后的传感信号进行无线发送和无线接收,实现了对传感信号的远距离传输,并且光栅传感阵列应用波分／时分复用原理,采用平行拓扑结构连接,组建了基于波分／时分复用的光纤光栅无线传感系统。更多还原

【Abstract】 To improve the practicability of the optical fiber grating sensor, the optical fiber grating sensing mechanism is discussed theoretically, and the technology of sending wirelessly is combined with the optical fiber grating sensing technique. Based on two technologies, a fiber Bragg grating wireless sensor system with combined wavelength-and-time-division multiplexing is set up. One is a wireless transmission system is composed of a single chip transceiver nRF905 and a chip microcomputer C8051F020 to make the sensor single, which pass electrical-to-optical and analog-to-digital conversion, to transmit wirelessly; the other is the fiber Bragg grating sensor array with the theory of wavelength-and-time-division multiplexing adopts the parallel topology configuration.更多还原
