Paper Abstract

There are great amount of information in the safety monitoring of huge structures and equipments and many kinds of sensors with promising long-term stability will be needed. Fiber Bragg grating (FBG) sensing technology is an effective means to realize the safety monitoring of huge structures and equipments. In this paper, the typical problems in the engineering application of safety monitoring of huge structures and equipments using FBG sensing technology have been analyzed. The key technologies of its engineering application have been studied, including FBG detecting technology in the harsh environment with high temperature and huge strain, the multipoint monitoring technology with huge capacity, and the demodulating technology. On that basis, several kinds of FBG sensing methods and products have been developed. The application examples of these products in a number of huge structures and equipments such as bridges, tunnels, huge rotating machines, and oil tanks have been presented, which will be helpful to the settlement of the related technical problems.
