【Abstract】 The actual condition monitoring system of the missile has to monitor so many parameters,since these parameters are distributed sidely and mainly acquired through electrical methods,the system is sophisticated and requires the ability of anti-electromagnetic interference sternly.According to these characters a new condition monitoring system based on fiber optic Bragg gratings are brought forward,then its specific components such as optic signal emitting sub-system,FBG sensing sub-system and signal demodulating & data processing sub-system are also proposed.At last,the actual problems of this new monitoring system and their potential solving methods are analyzed.更多还原
