Real-time monitoring of the security for the large construction with wireless FBG sensor network

The security monitoring of the large construction is always a problem for the city management in the world. The wireless fiber Bragg grating (FBG) sensor network applying to security monitoring for the large construction is one of the rapidly developing means. In the paper the feasibility analysis of the real monitoring with FBG sensor network is introduced. The wireless FBG sensor network composed the FBG temperature, strain and pressure sensor and wireless network communication technology is discussed. Some crucial basic problems, such as sensor characteristics, data acquisition and transmission, networking, real-time data processing and displaying, and the wireless sensor network development are also analyzed. The FBG sensor network with the ability of forecasting and warning has wide potential application perspective in real-time permanent monitoring.
