Abstract

Static ice pressure could threaten the hydraulic structures of cold regions. But due to its harsh detected environment, real-time and effective detection methods are urgently required. A fiber sensing system for dynamic SIP measurement is designed based on an FPGA. The FPGA as the main controller completes circuits for generating a pulse laser with high modulation depth and high extinction ratio, driving the pumping source of EDFA, and performing automatic data acquisition. An FBG is inserted into a fiber loop ring-down cavity to realize sensing, which can make the signal demodulation convert into the measured time. The sensing has the advantages of simple structure, easy demodulation and immunity to light source fluctuations. The designed SIP sensor demonstrates good linearity, stability and repeatability. Furthermore, an experimental setup of FBG ring-down cavity SIP system based on the FPGA is established to successfully detect continuous SIP variations, which shows the proposed system has the function for SIP detection. This study contributes to the long-term safety monitoring and risk warning of offshore platforms.

基于FPGA的光纤光栅环衰腔静冰压力检测系统

冰的静压会对寒冷地区的水工建筑物造成威胁。但由于其检测环境恶劣，迫切需要实时有效的检测方法。设计了一种基于FPGA的动态SIP光纤传感系统。FPGA作为主控制器，完成了产生高调制深度、高消光比脉冲激光器、驱动EDFA抽运源、自动数据采集等电路。在光纤环路衰荡腔中插入光纤光栅实现传感，将信号解调转换为被测时间。该传感器具有结构简单、解调方便、抗光源波动等优点。所设计的SIP传感器具有良好的线性度、稳定性和重复性。在此基础上，建立了基于FPGA的光纤光栅衰荡腔SIP系统实验装置，成功地检测了连续的SIP变化，验证了该系统具有SIP检测功能。该研究有助于海洋平台的长期安全监测和风险预警。

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
