Abstract
A kind of airborne multichannel Ethernet high-speed record device.The device greatly improves writing speed using parallel recording mode, and is identified using input channel number and input time in the index of record data, is capable of achieving multi-channel data synchronized playback.
Description
Art
The present invention relates to a kind of airborne multichannel Ethernet high-speed parallel tape deck, the speed of more than 4 times of the intrinsic recording rate of recording medium persistently record data can be exceeded.Meanwhile, the present apparatus can realize multi-channel synchronous data readback.
Background technology
Ethernet is, at present using extremely wide technology, in many concrete applications, there is the situation of the data for needing synchronous recording multichannel Ethernet transmission simultaneously.
Due to the limitation of the intrinsic read or write speed of recording medium and airborne equipment use environment, the writing speed of current various airborne recorders only has 1Gbps or so at the soonest.Such speed can not meet the growing demand to airborne writing speed.
The content of the invention
With array way be combined recording medium by the present invention, the record of the data transmitted on one internal bus of each medium module complete independently.Each module work does not interfere with each other, concurrent working.Recorded data is numbered by input channel and input time is identified.In data readback, can be played back by former channel number, and can by when system the time realize synchronized playback.
Brief description of the drawings
Accompanying drawing 1 is the general structure schematic diagram of the present apparatus.
Accompanying drawing 2 is the form construction design figure of the present apparatus.
Accompanying drawing 3 is the structure composition schematic diagram of the present apparatus.
Specific embodiment
1) whole device is made up of cabinet, motherboard, main control module, power module, 1~6 data aggregation module, logging modle.Each module is connected with motherboard.
2) power supply as required for motherboard transmits each module, lays the internal time Transfer pipe of 6 buses for transmitting data and a transmission unified clock；
3) main control module completes reception, the generation and transmission of unified clock of system time signal when the configuration of whole equipment, outside；Complete the output of present apparatus status signal；
4) ± 5V and ± 3V power supplys needed for the outside airborne dc sources of 27V for providing are converted to inside by power module, and each module is sent it to by motherboard；
5) data aggregation module receives 1~4 data of gigabit Ethernet transmission, and data are sent into logging modle by internal bus；
6) logging modle is made up of 6 recording units, each recording unit includes a recording medium (solid state record disk), one bus communication module and a modular converter, the data that are transmitted on each internal bus are monitored by bus communication module and recording medium is sent to after by modular converter data are packaged by the interface protocol of recording medium are recorded；
7) it is further provided with exclusive data and downloads software, in seconds the temporally downloading data from each recording medium successively, and by data recombination an into data file on PC.
