Large steel structure installation monitoring system based on optical fiber grating technology

The components of a stress and temperature monitoring system are first introduced in terms of large steel structure installation. In particular, working principles and methods of optical fiber gating technology are investigated on steel structure monitoring. In addition, the relevant software is developed using multithread programming technology. Compared with conventional approaches, this system possesses such advantages as high precision, high anti-interference ability, real-time acquisition and good applicability. By applying this stress and temperature monitoring system, the roof steel structure of Beijing Wukesong Indoor Stadium has been successfully installed.
