Abstract
The invention discloses airborne equipment for recording display pictures of an airplane display, namely airborne video data recording equipment (DRE). The DRE receives digital video signals transmitted from various video sources, and compresses, records and saves various video data synchronously by taking received Beijing time as reference time, and the DRE adopts a loop record mode, and when a memory space is about to be full with recorded data, the foremost data are covered automatically; the DRE has an event marking function, and when an airplane encounters an event during a flight and requires marking, the DRE can generate marking signals and record the event; and the DRE has a state indicating function, and can indicate a self-checking state, a fault state and a recording state of the equipment. The DRE is high in equipment overall integration degree, various modules inside the equipment are independent of one another, and the DRE is strong in data processing capacity and is easy to operate. By applying the DRE, the technical problem of synchronous recording of multiple video channels and playback issolved, and efficiencies of daily maintenance and troubleshooting of the airplane and flight training of pilots are greatly improved.

Technical field
The invention belongs to recording equipment technical field, is related to a kind of Airborne Video System data record and sets
It is standby.
Background technology
Modern big-and-middle-sized carrier majority is equipped with the electronic display meter with display screen to be used for
Show numerous critical datas of aircraft.For the ease of malfunction elimination, regular maintenance and flight training,
Need that the display picture of these display is recorded and played back.《Airplane design handbook》
17th《Avionics system and instrument》In have been proposed for regard to keep in repair troubleshooting class ginseng
Number measurement and the several technical method for recording, the weak point of these methods is safeguarded in shortening
Cycle and control maintenance cost aspect also have room for promotion.
The content of the invention
Present invention solves the technical problem that being：Propose that one kind possesses multichannel, high speed, Large Copacity
Video information collection, record and high-resolution video compression, the Airborne Video System data note of storage
Recording device.
The technical scheme is that：A kind of Airborne Video System data recording equipment, it is characterized by：

The external time of reception is transferred to video compressing module, video compress mould by block, CPU module
Block synchronous recording video signal, and by the video signal transmission after compression to data memory module.
Improve as one kind of the technical program, data memory module is arranged on airborne by socket
On video data recording apparatus.
Improve as one kind of the technical program, described Airborne Video System data recording equipment is adopted
Cycle index mode data storage.
Beneficial effects of the present invention are：System integration degree is high, matching component is few, small volume,
It is lightweight, the complexity of aircraft integral layout will not be increased；System can most 8 tunnels of synchronous recording
Video signal, it is powerful；Record adopts digital video signal, and picture playback is clear.
Description of the drawings
Fig. 1 is the principle schematic of the present invention
Specific embodiment
The present invention is achieved by the following technical solutions：System consists of an Airborne Video System number
According to recording equipment (hereinafter referred to as DRE).The outside 28V of power module reception of DRE is electric,
Use for video compressing module, CPU module, data memory module.The CPU module of DRE
Beijing time is received as time reference, for video compressing module synchronous recording from external reception
Each video signal.The number that CPU module is stored after by bus video compressing module is compressed
Data memory module is transferred to according to by video compressing module, data memory module can be from DRE
Quick-release.
As seen from Figure 1, DRE is made up of a LRU (LRU), its bag
The internal field replaceable units (SRU) for including has video compressing module, CPU module, data storage
Module and power module.
Each internal field replaceable units (SRU) function declaration is as follows：
1) video compressing module
Video compressing module receives DVI-D digital video signals and is acquired, compresses, and is formed
Code stream is stored in core buffer.
2) CPU module
CPU module receives the reliable Beijing time signal that other airborne equipments are provided, and completes
During upper electricity pair；And complete event flag and State- output work(by carrying out communication with other modules
Energy；CPU module is therefrom read compressed by PCI-E bus access video compressing modules
Video codeword data stream, and by SATA buses write data memory module in.
3) data memory module
Storage video compressing module collection, it is compressed after video data.Data memory module has
There is quick-detachment function, can unload to be placed on special playback apparatus from DRE and read regarding for its storage
Frequency evidence.
4) power module
Major function is to complete, to the Isolation of direct current 28V power supplys and conversion on machine, to carry
For the various power supplys needed for each electronic units of DRE, and direct current 28V isolation on machine is converted to
Communicated with CPU module after low level discrete magnitude signal, to realize event flag and state
Output.
DRE adopts cycle index mode, before covering most automatically when memory space will be write all over
The data in face.DRE peripheral states are indicated and event flag function, when aircraft is awing sent out
Make trouble part and when needing labelling, DRE can produce marking signal and record in a storage module.
Different according to the number of the video source for being recorded, the record time of DRE can be different, typically should
No less than 25 hours or 3 Sorties.
