To achieve a long-term and real-time monitoring of the warship and submarine structural state,a monitoring system had been built which was based on fiber Bragg grating sensors.It also had designed the overall system hardware circuit,software flow and the flow of peak searching algorithm.The following work is to validate the system functions,and it carried out the multi-channel simultaneous real-time calibration functions of wavelength demodulation.Because the scanning frequency could be up to 4 kHz,this system was able to quickly monitor the structural state and it could be directly applied to engineering.
