北京理工大学珠海学院2020届本科生毕业论文ABSTRACTThe Airborne survival radio station is the only communication tool for pilots afterparachuting.It can establish contact with search and rescue equipment throughamplitude modulation voice communication,vocoder voice communication,beacontransmission,GPS positioning,short message transmission and other ways to provideguarantee for timely search for pilots and ensure the safety of pilots.Therefore,theperformance of life-saving radio is directly related to whether pilots can be accuratelyfound and rescued.At present,in order to improve and perfect the lifesaving system onthe airplane,the airplane manufacturing industry in our country urgently needs toresearch a reliable lifesaving radio communication system.Life-saving radio station is apersonal hand-held radio station.It is used by pilots and aircrew members who crash orland planes or helicopters to communicate with rescue service planes or rescuehelicopters and guide them to the crash site so as to increase the survivability andrescue capability of pilots or aircrew members of the crashed planes.By exploring theprinciple and failure mechanism analysis of the airborne life-saving radio station,thispaper can greatly reduce the time spent in troubleshooting,and workers can have amore thorough understanding of the possible failure types of the radio station whenoverhauling the life-saving radio station,so as to overhaul the aircraft more efficiently.Byanalyzing the common faults,studying the fault mechanism,designing the fault equationand finding out the faults in different situations.Life-saving radio station is the mosteffective communication tool for pilots after parachuting.Life-saving radio station is themost effective communication tool for pilots after parachuting.In order to avoidoccurrence of relevant situations,failure mechanism shall be thoroughly analyzed andoccurrence of similar cases shall be strictly prevented.Key words:modulation/demodulation of aircraft lifesaving communication stationI1
