A Portable Ground Test Equipment for Multiple Data Storage

Abstract

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.

Description

technical field [0001] The invention relates to a portable ground testing device for multi-channel data storage. Background technique [0002] LVDS is low-voltage differential signal. The core of this technology is to use extremely low rolling swing to tell differential transmission data, which can realize point-to-point or point-to-multipoint connection, with low power consumption, low bit error rate, low features such as crosstalk and low radiation. LVDS has been more and more widely used in systems that require high signal integrity, low jitter and common mode characteristics. LVDS is mainly applicable to the field of high-speed data transmission. [0003] In the field of portable ground testing, general ground testing equipment has few LVDS data storage channels, and cannot simultaneously achieve multi-channel high-speed data storage and small size for portability. Contents of the invention [0004] The object of the present invention is to overcome the deficiencies...
