Description
Technical field
The utility model design aircraft navigation position fixing system, specifically, relates to a kind of aircraft black box position reporting and course line track channel.
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 for the call with ground on the dialogue of aircrew on logging machine, machine, and the various sound in cabin.Black box is very firm, can resistance to air crash time fierce impact and high temperature hot flame.
Black box do not have radio transmission apparatus, by land air crash, the luminous zone on the bright shell of just its salmon pink that black box reminds people to note and shell.
The parts that black box uniquely externally can send signal are called subsea beacon (ULB), and subsea beacon starts after chance 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 because the subsea beacon volume of black box is little, power is also little, generally, the maximum about black box acoustic signals that can receive within several kilometer range of shipboard sonar, the effective scope of detection of small handheld sonar then only has hundreds of rice.Be less than the relative boundless sea of investigative range of several kilometers, stronger than " looking for a needle in a haystack " not how many.
The flying quality recorded in existing black box, has more than 700 flying quality, uninterrupted recording during flight.Data volume is not little, and engineering all can regularly take CD to go aircraft is downloaded.Also have cockpit voice recording, originally only record 30 minutes, present real time recording, can be understood as a continual satellite phone and adds real-time recording.This cost performance is not high, and cost is too large, and this expense can not improve safety.Transmit this kind of data and also probably require that disturbance rejection is strong, strong security, this technology will use satellite, if military words are out of question, if involve civilian, or problem short of money.Also relate to aviator's right of privacy in addition, real time communication, all dialogues all inside, ground can be monitored at any time, likely can be invaded aviator's privacy.
In addition, " horse boat event " is learnt, existing aircraft tracking performance is poor, and black box is not easily found, and this just needs to utilize autonomous Big Dipper technology to solve the problems referred to above.
Summary of the invention
The utility model can sink under water with accident aircraft for the black box existed in existing aircraft, and not easily found, course line is difficult to tracked defect, provides a kind of aircraft black box position reporting and course line track channel to solve the problem.
Scheme of the present utility model is by realizing like this: construct a kind of aircraft black box position reporting and course line track channel, comprise the main black box of existing machine, flight recorder and voice recording instrument is provided with in main black box housing, and store the stocking system of above-mentioned recording instrument, also comprise and be arranged on Big Dipper transmitter unit in cabin and secondary black box, the big-dipper satellite signalling device can being monitored tracking by air traffic control centre is in real time provided with in described secondary black box, and the back-up device be connected with stocking system in main black box;
Also backup power is provided with in described secondary black box;
Described secondary black box is arranged on the position that ejectable goes out airframe, catapult-launching gear is provided with bottom described secondary black box, described catapult-launching gear is connected with accident diagnoses sensor, and after accident diagnoses sensor-triggered, catapult-launching gear starts and can launch out outside body by secondary black box;
Described secondary black box is provided with air bag, secondary black box can be wrapped up completely, can float on the water surface after air bag expands, and described air bag expands and triggered by catapult-launching gear.
General plotting of the present utility model is: set up a Big Dipper transmitter unit first aboard, thus when aircraft is at normal flight, the location information that the Big Dipper can provide aircraft real-time for blank pipe mechanism; In addition, on the basis of original main black box, set up one can share and store the secondary black box of main black box information, when unusual condition appears in aircraft, when accident diagnoses sensor sensing judges that aircraft is in abnormal condition, then start catapult-launching gear, secondary black box is launched out outside airframe, now, after air bag in secondary black box is launched out, can automatic inflating be realized, make black box just in case when dropping on the water surface, can continue floating.Meanwhile, the Big Dipper utilizes the big-dipper satellite signalling device in secondary black box to position, thus obtains the locating information of secondary black box.
In the utility model, the above accident diagnoses sensor comprises acceleration induction module, vibration induction module, height induction module and seawater induction module.Above-mentioned module can judge aircraft acceleration/accel, vibration, residing height whether exception or be in air crash state, and in addition, seawater induction module can sense whether touch seawater.Above-mentioned module, all can adopt existing technology to realize.
In the utility model, as further improvement, described Big Dipper signalling device comprises BeiDou-I satellite position fixing system.By Big Dipper position fixing system in a device, be convenient to lock rapidly aircraft accident position, so that rapid deployment is searched and rescued.
In the utility model, as further improvement, described Big Dipper signalling device comprises BeiDou-I satellite position fixing system, the Big Dipper/GPS dual-mode position fixing system, radio signals feedway and communication control unit.By Big Dipper position fixing system in a device, be convenient to lock rapidly aircraft accident position, so that rapid deployment is searched and rescued; And the Big Dipper/GPS dual-mode position fixing system can pass through radio signals feedway, signal is transmitted to the rescue worker of periphery; Communication control unit can control No. one, the Big Dipper and transmitting time interval, radio station, avoid the two electromagnetic interference, also blank pipe department can be made to read part critical data in secondary black box by communication controller, directly be sent to air traffic control centre by big-dipper satellite, in air crash, be convenient to higher level work out rescue plan fast.
In the utility model, preferably, described radio signals feedway emissive power is 400-600mW.
Of the present utility model have outstanding actual features and marked improvement to be:
1. the utility model can follow the trail of airplane information by actv. by arranging Big Dipper transmitter unit, 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 utility model, novelty add secondary black box, thus making secondary black box when running into emergency situations, the very first time can eject cabin, thus avoid valuable information to be destroyed.
3. in addition, secondary black box have employed autoprotection device, by arranging air bag, making it can be floating when falling into the water surface, avoiding falling into seabed and cannot being searched.
4. the utility model technology maturation, can adopt existing technology to realize, and have great effect to aircraft navigation security monitoring.
