Description
Technical field
The present invention designs aircraft navigation alignment system, specifically, relates to a kind of aircraft black box position reporting and system is followed the tracks of in course line.
Background technology
Black box formal name used at school is " flight recorder " (Flight Recorder).The flight recorder that on passenger plane, black box is installed has 2, and one is aeroplane data recorder (FDR), be responsible for the record-setting flight time, speed, highly, the data such as the aircraft rudder surface degree of bias, engine speed；Another is cockpit voice recorder (CVR), is responsible on logging machine the call with ground on the dialogue of aircrew, machine, and the various sound in cabin.Black box is the firmest, is resistant to fiercely impact and high temperature hot flame during air crash.
Radio transmission apparatus is not had, the luminous zone by land if air crash, on the bright shell of simply its salmon pink that black box prompting people note and shell on black box.
Black box uniquely can externally send the parts of signal and be called subsea beacon (ULB), and subsea beacon starts after meeting water, and a per second secondary frequencies is the acoustic signals (attention is acoustic signals) of 37.5KHz, sustainable work 30 days.
The acoustic signals that black box sends under water can only be detected in water by sonar, but owing to the subsea beacon volume of black box is little, power is the least, generally, shipboard sonar maximum about can receive the black box acoustic signals within several kilometer range, and the effective scope of detection of small handheld sonar then only has hundreds of meters.Investigative range less than several kilometers is relative to boundless sea, strong the most not how many than " looking for a needle in a haystack ".
In existing black box, the flying quality of record, has more than 700 flying quality, uninterrupted recording during flight.Data volume is the least, and engineering all can periodically be taken CD to go on aircraft and download.Also have cockpit voice recording, originally only record 30 minutes, it can be understood as a continual satellite phone adds real-time recording if present real time record.This cost performance is the highest, and cost is too big, and this expense can not improve safety.Transmit this kind of data also likely require anti-interference by force, strong security, this technology satellite to be used, if out of question if military, if involving civilian, or problem short of money.Additionally relating to pilot's right of privacy, real time communication, all of dialogue the most inside, ground can be monitored at any time, it is possible to can invade pilot's privacy.
Additionally, " horse boat event " is learnt, existing aircraft tracking performance is poor, and black box is difficult to found, and this is accomplished by utilizing autonomous Big Dipper technology to solve the problems referred to above.
Summary of the invention
The present invention is directed to black box present in existing aircraft to sink under water with accident aircraft, be difficult to found, course line and be difficult to tracked defect, it is provided that system is followed the tracks of to solve the problems referred to above in a kind of aircraft black box position reporting and course line.
The solution of the present invention is by being achieved in that: system is followed the tracks of in a kind of aircraft black box position reporting of structure and course line, including the main black box of existing machine, flight recorder and voice recording instrument it is provided with in main black box housing, and store the stocking system of above-mentioned monitor, also include Big Dipper transmitting device and the pair black box being arranged in cabin, be provided with, in described secondary black box, the big-dipper satellite signalling device that tracking can be monitored by air traffic control centre in real time
, and the back-up device being connected with stocking system in main black box；
It is additionally provided with stand-by power supply in described secondary black box；
Described secondary black box is arranged on ejectable and goes out the position of airframe, it is provided with catapult-launching gear bottom described secondary black box, with accident, described catapult-launching gear judges that sensor is connected, after accident judges sensor-triggered, catapult-launching gear starts and can be ejected outside body by secondary black box；
Described secondary black box is provided with air bag, and when can floating on the water surface by fully wrapped around for secondary black box after airbag inflation, described airbag inflation is triggered by catapult-launching gear.
The general plotting of the present invention is: set up a Big Dipper transmitting device the most aboard, thus when aircraft is at normal flight, the Big Dipper can be the positional information that blank pipe mechanism offer aircraft is real-time；Additionally, on the basis of original main black box, set up a secondary black box that can share and store main black box information, when unusual condition occurs in aircraft, accident judges that sensor sensing judges when aircraft is in abnormal condition, then start catapult-launching gear, pair black box is ejected outside airframe, now, after air bag in secondary black box is launched out, automatic inflating can be realized so that when black box is just in case falling on the water surface, can be the most floating.Meanwhile, the Big Dipper utilizes the big-dipper satellite signalling device in secondary black box to position, thus obtains the location information of secondary black box.
In the present invention, the above accident judges that sensor includes acceleration induction module, vibration induction module, highly induction module and sea water induction module.Above-mentioned module may determine that aircraft acceleration, vibration, residing height whether exception or is in air crash state, it addition, sea water induction module can sense whether touches sea water.Above-mentioned module, all can use existing technology to realize.
In the present invention, as further improving, described Big Dipper signalling device includes BeiDou-I satellite alignment system.By number alignment system of the Big Dipper in a device, it is simple to locking aircraft accident position rapidly, in order to rapid deployment is searched and rescued.
In the present invention, as improving further, described Big Dipper signalling device includes BeiDou-I satellite alignment system, the Big Dipper/GPS dual-mode alignment system, radio signals discharger and communication control unit.By number alignment system of the Big Dipper in a device, it is simple to locking aircraft accident position rapidly, in order to rapid deployment is searched and rescued；And the Big Dipper/GPS dual-mode alignment system can pass through radio signals discharger, transmit signals to the rescue worker of periphery；Communication control unit can control the Big Dipper one and radio station transmitting time interval, avoid the two electromagnetic interference, blank pipe department can also be made by part critical data in the secondary black box of communication controler reading, it is sent directly to air traffic control centre by big-dipper satellite, air crash is easy to higher level and quickly works out rescue plan.
In the present invention, preferably, power launched by described radio signals discharger is 400-600mW.
Have prominent actual features and the marked improvement of the present invention be:
1. the present invention can effectively follow the trail of airplane information by arranging Big Dipper transmitting device, thus avoids aircraft to occur and situation about being lost contact by blank pipe mechanism at the normal Intermediate Course that travels.
2. in the present invention, the addition pair black box of novelty, so that secondary black box is when running into emergency situations, can eject cabin the very first time, thus avoid valuable information destroyed.
3. it addition, secondary black box have employed autoprotection device, by arranging air bag so that it can be floating when falling into the water surface, it is to avoid falls into seabed and cannot be searched.
4. the technology of the present invention is ripe, existing technology can be used to realize, and aircraft navigation security monitoring is had great effect.
