Embodiment 1

[0021] The external storage device 102 used by the transfer device in this embodiment is multiple SATA hard disks, and two SATA adapters 103 are taken as an example. The user control unit 104 and the transfer main control unit 101 are all packaged on the host computer, and the transfer adapter 103 adopts a SATA adapter 1031 (see image 3 ) is connected with the SATA hard disk, the switching unit 106 adopts a switching board, the power management unit 105 adopts a power board, and each functional structure inside the transfer device (including a host, a switching board, a power board, and an adapter 103 connected to different external storage devices) All the rooms use PCIe as the interface, and the various functional structures on the dump device are connected through the PCIe bus backplane to form the data path and signal connection of the PCIe interface to ensure high-speed serial transmission of data. The switching board can realize the switching of the data paths of the mu...

Embodiment 2

[0024] The present embodiment adopts the above-mentioned dumping device mainly for dumping of airborne data equipment, and needs to access external storage devices 102 of various special-purpose airborne interfaces, such as: FC optical fiber interface memory card or serial RapidIO (SRIO) interface storage Cards, etc., have developed corresponding FC transfer adapters and SRIO transfer adapters for the FC optical fiber interface and SRIO interface. The structure of this adapter is similar to the SATA adapter 1031. The interface protocol is uniformly converted into the high-speed data transmission protocol inside the device, connected to the unified internal high-speed data interface, and then switched to the corresponding data path by the user according to actual needs, so as to perform data dump processing, and then realize multi-channel data high-speed transfer.

[0025] The dumping device of the present invention utilizes the corresponding transfer adapter 103 to connect the...

Abstract

The invention discloses a multichannel data high-speed transferring device which is characterized by comprising at least one transfer adapter, a switching unit, a transfer main control unit, a power management unit and a user control unit, wherein one end of the switching unit is connected with the transfer adapters, and the other end of the switching unit is connected with the transfer main control unit; the transfer adapters are respectively connected with different external storage devices; the transfer main control unit is simultaneously connected with the user control unit and the power management unit; the transfer main control unit is capable of converting external power supply into power supply modes required by all the adapters by virtue of controlling the power management unit. The multichannel data high-speed transferring device is capable of realizing compatible connection and processing of different existing storage devices, and shortening the transfer time while ensuring the data high-speed transmission, has higher expansibility and flexibility, and is applicable to high-speed real-time data transfer of a mass-memory unit.

Description

technical field [0001] The invention relates to the technical field of storage, in particular to a multi-channel data high-speed transfer device. Background technique [0002] Due to the limitations of the flight environment, the airborne electronic system cannot transmit data back to the ground in real time during the mission. Therefore, it is necessary to record a large amount of flight data in the onboard storage device first, and then transfer the recorded data to the ground after the mission is completed. Save to ground equipment for post-processing and playback. [0003] Since storage device solutions are designed according to the requirements of the airborne system, there are large differences in their external interfaces, such as SATA interfaces, RapidIO interfaces, and FC optical fiber interfaces. In addition, the dimensions and power supply of the affected equipment will be different. The current common technical solution is to equip each storage device with an i...
