光纤传感技术在物联网中的应用

物联网是当前的一个研究热点,而光纤传感技术在物联网中的应用已经引起了广泛关注。物联网的技术构成有4个层次,分别是用户与应用接口、数据处理技术、数据传输网络、传感网络。在物联网中要用到各种各样大量的传感器。传感器可用于感知各种各样的环境参数,如温度、重力、光电、声音、位移、振动等,为物联网提供最原始的数据信息。对光纤传感器的结构、分类以及其在物联网中的应用实例进行介绍,如光纤陀螺,光纤水听器、光纤光栅传感器、光纤电流传感器。最后介绍了基于布里渊效应的连续分布式光纤传感技术在物联网中的前沿应用。

Optical Fiber Sensing Technology Application in Internet of Things

The Internet of things is a current hot topic, and optical fiber sensor technology application in the Internet of things has already caused wide concern. The Internet of things is consisted of four levels. They are user and application interface, data processing technology, data transmission network and sensor network. A large number of varied sensors are needed in the Internet of things. Sensor can perceive all kinds of environmental parameters like temperature, gravity, photo-electricity, sound, displacement and vibrate to provide the original data information. The structure of the sensor, classification, and its applications in the Internet of things like optical fiber gyro, optical fiber hydrophone, optical fiber grating sensor and optical fiber current sensor are introduced. Forefront application in the Internet of things of continuous distributed optical fiber sensing technology based on Brillouine effect is also introduced.
