摘要（英）：

The invention discloses a multi-channel data storage portable ground testing device. The device comprises a low voltage differential signaling (LVDS) data transmission panel and a master control circuit board. The LVDS data transmission panel comprises a field programmable gate array (FPGA) processing module, an LVDS driver, a plurality of USB controllers and a plurality of eMMC storage modules. The master control circuit board comprises a master control processing module, a PCH module and an interface chip. The first in first out (FIFO) port of the FPGA processing module is connected with the plurality of USB controllers respectively, the eMMC control end of each USB 3.0 controller is connected with one eMMC storage module, each USB controller is connected with the USB port of the PCH module through multi-channel USB interfaces, the FPGA processing module is connected with the PCIe port of the PCH module through a PCIe interface, the master control processing module is connected with the PCH module and is further connected with a first external interface through the interface chip. The device is small in size, low in power consumption, convenient to carry, capable of collecting four-channel LVDS data simultaneously and capable of storing six-channel LVDS data at a high speed simultaneously.
