Internet of Things Enabled Structural Health Monitoring Using Fiber Bragg Grating Sensors
摘要
An accurate and real-time time sensing of the parameters plays a significant role in Structural Health Monitoring systems (SHM) as they are prone to numerous environmental conditions. This aspect can be addressed using Fiber Bragg Grating sensors. The fiber Bragg grating sensor is only desired as they are immune to Electromagnetic radiation. The fiber Bragg grating sensors and the Internet of Things are the key enablers for online real-time sensing. In this paper, FBG was bound to the base plate of the suspension bridge structure. A thermal loading was applied, and the strain was determined using the change in the wavelength of Bragg grating through the FBG interrogator. The Interrogator was connected to the gateway through which the real-time value of the strain can be measured from a long distance. The experimental setup is demonstrated in the paper.
