Detailed description of the invention
The aircraft each freight space audio/video information record monitoring dress with specific embodiment, the present invention provided below in conjunction with the accompanying drawings
Put and be described in detail.
As it is shown in figure 1, aircraft each freight space audio/video information record supervising device that the present invention provides includes DVR
1, power supply logics module 2, PoE power supplying switch 3 and multiple high-definition camera 4；Plurality of high-definition camera 4 is separately mounted to
In driving cabin, main cabin, cargo hold, and it is connected with DVR 1 by netting twine simultaneously；DVR 1 and PoE power exchange
Machine 3 is connected；Power supply logics module 2 is connected with the alternating current power supply on DVR 1, PoE power supplying switch 3 and aircraft
Connecing, for the alternating current on aircraft being converted to unidirectional current, thus providing direct current for DVR 1 and PoE power supplying switch 3
Electricity.
Described aircraft each freight space audio/video information record supervising device also includes passing through VGA port with DVR 1
The display being connected, for the information that DVR 1 transmits being shown in real time, maybe shows the content of storage
Show, inquire about for the relevant personnel and monitor.
Described aircraft each freight space audio/video information record supervising device USB that also includes being connected with DVR 1 deposits
Storage equipment, for copying to external memory by the data of storage.
As in figure 2 it is shown, the high-definition camera 4 in described driving cabin is arranged on the top of driving cabin, it is used for recording driving
The operation of member；According to particular demands, it would however also be possible to employ the photographic head of band sound-recording function, for recording the voice messaging of driver.
This recording mode can only record the information of nearest 30 minutes than existing voice recorder, and the time of record is much longer.
As it is shown on figure 3, the high-definition camera 4 in described main cabin is arranged on the top in main cabin, use band sound-recording function
Photographic head, the front and rear in main cabin is respectively mounted one, if needing the height that can also increase forward at middle part/arrange backwards
Clear photographic head 4, the action of personnel and voice in recording main cabin.
As shown in Figure 4, the high-definition camera 4 in described cargo hold is arranged on the backside top of cargo hold, so can shoot
The process of goods up and down, the movement of personnel and the equipment of front portion at cargo door, if desired for also can install court in cargo hold front portion
The high-definition camera 4 of rear setting.
As it is shown in figure 5, described DVR 1 is arranged on airplane tail group with PoE power supplying switch 3.Wherein PoE powers
Switch 3 uses IEEE802.3af standard, provides electric power by conventional ethernet line, thus protect while transmission data
Card is while transmitting data signal for high-definition camera 4, moreover it is possible to provide unidirectional current for these equipment.
As shown in Figure 6, described power supply logics module 2 has three inputs, respectively with airspeed sensor, lubricating oil pressure
Sensor is connected with APU starter motor, and outfan connects DVR 1 and PoE power supplying switch 3.
Now aircraft each freight space audio/video information record supervising device operation principle that the present invention provides is described below: make
By process, utilize the operation of the high-definition camera 4 Real-time Collection driver being arranged on each freight space and call, the display of instrument,
The information such as the movement of personnel in the action of crew member and passenger and call, cargo hold, luggage handling and equipment work, then by this
A little information send DVR 1 to through PoE power supplying switch 3, and DVR 1 controls the operation of whole device, and it is first
First above-mentioned information being carried out video compression/decompression, complete the storage of video data, information is continuous cycle index, and can
To be played back by coupled display, for monitoring, coupled mobile storage can also be copied to simultaneously
In equipment.
It addition, DVR 1 is according to the difference of storage time requirement, different size of hard disk can be chosen to install, during recording
Between from tens hours to hundreds of hour.After hard disk is filled with, automatically erase the content recorded at first, cycle index, the most not
The content of middle recording can be lost.
Additionally, due to the unidirectional current of aircraft is 28V, the supply voltage of DVR 1 is 48V, therefore can not directly use
Powered by direct current, so using power supply logics module 2 that the alternating current on aircraft is converted to unidirectional current, inputs DVR 1.
As shown in Figure 6, it receives motor oil pressure signal, airspeed signal, APU signal to the structure of this module, three signals be or
Relation, when three signals there being a signal desirable value occurs, this device i.e. give DVR 1 power.
1, for receiving the lubricating oil pressure signal of electromotor, when motor oil pressure from low to high time, show electromotor
Have been turned on, power now to DVR 1；
2, be used for receiving airspeed signal, when air speed more than 60 nautical miles/little constantly, its give DVR 1 power；
3, being used for receiving APU signal, when APU starts, aircraft power system obtains alternating current, and now it gives HD recording
Machine 1 is powered.
