Example Embodiment

[0020] Example 1

[0021] The external storage device 102 to which the dump device in this embodiment is connected is multiple SATA hard disks, and two SATA adapter adapters 103 are taken as an example. The user control unit 104 and the dump main control unit 101 are both packaged on the host, and the transfer adapter 103 uses a SATA adapter 1031 (see image 3 ) Connected to the SATA hard disk, the switching unit 106 uses a switching board, and the power management unit 105 uses a power board. The internal functional structures of the transfer device (including the host, the switching board, the power board and the adapter 103 connecting different external storage devices) PCIe is used as the interface between them, and the 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...

Example Embodiment

[0023] Example 2

[0024] In this embodiment, the above-mentioned dumping device is mainly used for dumping of on-board data equipment, and external storage devices 102 with a variety of dedicated on-board interfaces are required, such as FC optical fiber interface memory cards or serial RapidIO (SRIO) interface storage. The corresponding FC adapter and SRIO adapter have been developed for FC optical fiber interface and SRIO interface. The structure of the adapter is similar to SATA adapter 1031. The data of different external storage devices 102 are transferred through corresponding adapter 103. The interface protocol is uniformly converted into the internal high-speed data transmission protocol of the device, connected to the unified internal high-speed data interface, and then the user switches to the corresponding data path according to actual needs, so as to transfer the data and realize the multi-channel data The high-speed dump.

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...
