High Speed Data

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.

Asynchronous Parallel

A high-speed data acquisition card using USB 3.0 interface has been designed in order to solve the problem that traditional data acquisition card could not take both data transmission bandwidth and easy connection with PC into account. The data acquisition card controlled the dual-channel 12-bit 20Msps ADC for asynchronous parallel sampling using FPGA as core control module, which made the sampling rate up to 40Msps. The sampled data which was processed by FPGA transferred synchronous from FIFO interface to PC via USB controller. The basic structure of hardware and the basic design method for software and firmware were given in this paper, in which how to use FPGA to realize FIFO was elaborated in detail. The timing simulation of using asynchronous parallel A/D conversion technology and using ADC device of 40Msps sampling rate for FIFO internal data transmission were simulated respectively, thus verified the reliability of asynchronous parallel A/D conversion.

The design of high speed data acquisition and storage system is based on Labview. It can not only achieve high accuracy and high data rate but also use the software and hardware synchronization trigger to complete the multi-channel continuous real-time monitoring of the acquisition and storage periodic signal. Which is similar to the function of the oscilloscope. This system is based on high speed data acquisition card of NI company and Labview 2012 for PC software development platform. Data acquisition card is used to finish data acquisition of periodic signal through the serial port. It also collect data upload to upper computer. Upper computer collect data for storage display and analysis to realize the real-time monitor of multi-channel analog. The design of the sampling channel is 2, the sampling rate up to 200M/s, the sampling precision is 12 bits, and the sampling depth is 2000. Lots of verification prove that the design has good compatibility, performance and stability of the collection. Data error is negligible by analyzing the data collected. More importantly, the design can be as far as possible to restore the actual signal source data without distortion. This paper provides a portable design for high speed data acquisition, which can be widely applied in the engineering of modern test and measurement technology.
