Speed Data Transmission

Along with the rapid development of computer technology, high speed data acquisition and storage system has been widely applied in plenty of engineering fields, such as radar, aerospace industry, communication, etc. In order to satisfy the increasing requirement, we present the design structure of a novel integrated instrument for ultra-high speed data acquisition and storage, which is composed of ultra-high speed data acquisition, high speed data transmission and solid storage three main sub-systems. The detailed design and realization of the sub-systems are presented. We test and analysis the performance of the integrated instrument and the actual results show that the instrument performs stably and provides excellent speed and precision.

To improve data transmission performance of the data acquisition card, a design of high-speed data transmission system is proposed in the thesis. Using FPGA of programmable logic devices, adopting Verilog HDL of hardware description language, the design of modularization and DMA transmission method is implemented in FPGA. Eventually the design implements the data transmission with high-speed through PCI Express interface. Through simulation and verification based on hardware system, this design is proved to be feasible and can satisfy the performance requirements of data transmission in the high-speed data acquisition card applied in high-speed railway communication. The design also has some value of application and reference for a universal data acquisition card.
