Abstract

The invention discloses a large-capacity data unloading system which comprises a data storage module and a data server and further comprises a data unloading box. The data storage module and the data server are connected through the data unloading box, and the method comprises the steps of storing the collected data to a data storage device through caching and via a second FPGA module of the data storage module; after the data storage module is inserted into the data unloading box, enabling the second FPGA module to interact a control instruction with a first FPGA module of the data unloading box through a control interface, and sending the data of the data storage device to the data unloading box through a high-speed data interface under the control of the control instruction; enabling the first FPGA module of the data unloading box to interact control data with a data server through an Ethernet interface; and under the control of the control data, enabling the data unloading box to read the data in the data storage module, and forwarding the data to the data server through an optical port. According to the invention, the data of the whole data transfer can reach several GB / s, and the data transfer speed is increased by several times compared with the traditional data transfer speed.

Description

technical field [0001] The invention relates to the technical fields of communication and telemetry, in particular to a large-capacity data dump system and a dump method. Background technique [0002] In the fields of communication, telemetry, big data applications, etc., it is necessary to store the wireless signals collected on-site during the task in the data storage module. After the task is over, transfer the data in the storage module to other storage devices such as the data server hard disk system media to realize data backup, follow-up analysis, etc. The structure of the traditional data transfer system is as follows: figure 1 shown. This kind of system architecture often adopts traditional Gigabit Ethernet, whose data rate cannot meet the needs of large-capacity data dumping. Taking the dump of an 8TB data module as an example, it takes at least 8,000 seconds to unload through Gigabit Ethernet, which brings a large delay to the user's data dump and poor user exp...
