Satellite-signal；Voice driven unit driving voice playing unit carries out voice broadcast, and power control unit is according to the program of setting
Open and close the power supply of sensor.
The Big Dipper of the present utility model searches and rescues report position instrument and employs a variety of calling for help triggering modes, including acceleration detection, air pressure
Difference detection, temperature difference detection, seawater detection, manual SOS.Pilot can be at 4~5 seconds in the moment launched from cabin, acceleration
More than 9.5g is inside rapidly risen to, this make it that detecting acceleration turns into a kind of method that the pilot in danger triggering Big Dipper is reported and submitted, north
Bucket is searched and rescued and accelerates to detection module inside report position instrument, once detecting the transition of acceleration, will trigger Big Dipper RDSS modules
Distress signals are externally sent, untill information is sent successfully；Air pressure of the pilot inside and outside the moment launched from cabin, cabin
Difference can vary widely (be an atmospheric pressure in cabin, generally 1000hPa, air pressure is inversely proportional cabin with height above sea level outside,
Height above sea level often increases 8.43m, and air pressure reduces 1hPa), air pressure change is detected by baroceptor, once find air pressure change
Rate is more than certain threshold value, just starts Big Dipper RDSS modules and sends distress signals；Pilot often declines 1000 after cabin is ejected
Rice, temperature can increase by 6.5 degree, and general pilot has to fall earthward for 5~6 minutes during parachute jumping, utilizes the short time
Temperature difference change detection, pilot in danger can also be judged, so as to trigger Big Dipper RDSS modules send distress signals；If fly
Office staff falls into sea, can trigger the chance taps of lifesaving report position machine, and triggering Big Dipper RDSS modules send distress signal；Also one
The transmission of kind distress signal is exactly the triggering of SOS buttons, as long as distress personnel presses SOS with hand calls for help key, will trigger the Big Dipper
RDSS modules send distress signal.The combination of various triggering modes, it is ensured that the transmission of Big Dipper distress signal, ensure distress personnel and
When succoured.
The Big Dipper of the present utility model is searched and rescued Big Dipper RDSS modules in report position instrument and sealed using profit core RXM608 microminiature stamps mouth
The radio frequency baseband integrated module of dress, it is necessary to the distress signals of transmitting are sent to Big Dipper RDSS modules by serial communication from MCU,
Big Dipper RDSS modules are added identifiable message part row information of going forward side by side to distress signals and beaten by being interacted with Big Dipper generation IC-card
