The electromagnetic radiation will result in informa- tion leakage being recovered when computers work. This article presents a high-speed real-time data acquisition system based on peripheral component interconnect （pci） bus and field programmable gate array （FPGA） for sampling electromagnetic radiation caused by video signal. The hardware design and controlling flow of each module are introduced in detail. The sampling rate can reach 64 Msps and system transfers speed can be up to 128 Mb/s by using time interleaving, which increases the overall sampling speed of a system by operating two data converters in parallel.

In order to achieve the signal acquisition and control requirements of engine system, this paper designs a kind of high-speed multi-channel data acquisition card, which is built with Altera Cyclone series FPGA EP1C12Q240C8 N as the main control chip, using VHDL to realize the real-time acquisition and output control for high-speed multi-channel analog and switch quantity, then the card communicate portable PC monitoring and control system with pci9054 bus. The data acquisition card can complete 24 way switch quantity input, 6 way switch quantity output, 3W programmable resistance output, engine rotational speed sampling, bridge circuit voltage sampling, surge pulse sampling and bridge resistance sampling. And simple, reliable, practical, portability and flexibility are the features of the system, etc. This paper mainly elaborates the design idea and realization method of data acquisition card, and verified by experiments and practical application.

ARINC429是目前航空通讯中使用很广泛的通信协议,它规定了航空各系统间或系统与设备间的数据传输要求,是航空信息传输的主要方式。实现这种通信协议的硬件架构,在市场上有好几种,其中使用很广泛的架构是DSP和FPGA作为核心器件实现其协议。DSP作为主控制器和上位主机进行数据交换,同时控制FPGA内部各个ARINC429通道协调工作;FPGA用来实现ARINC429协议的逻辑要素。而本文采用SOPC技术,仅用FPGA作为核心器件实现其协议。作为一种新的尝试,我所作的工作主要包括以下几个方面:1.根据项目的需要,深入了解了ARINC429规范和与之相对应的俄罗斯标准,定义了系统的功能,对系统的软硬件进行了划分。2.细致研读pci总线规范,对Lattice公司的33M pci Target IP的各个模块进行了完整的消化,完成ARINC429通信卡的pci地址分配。3.在pci总线和Avalon总线之间,由于时钟域不同,需要用FIFO在两个总线之间缓存数据字。完成FIFO控制与询问控制器设计,这包括功能接口定义、内部模块划分、RTL编码、TestBench编写、Modelsim环境下仿真。4.根据ARINC429规范要求,完成ARINC429协议收发器的功能接口定义、内部模块划分、RTL编码、TestBench编写、Modelsim环境下仿真。5.确定本项目所需的FPGA型号、配置芯片、电源芯片、晶振、电平转换芯片、调制解调芯片等元器件。参照Cyclone手册和Altera公司NIOSII开发板原理图,用Protel DXP完成了ARINC429通信卡的硬件原理图设计和PCB设计。6.利用Altera公司的开发工具:SoPC Builder、Nios II IDE集成设计环境、Quartus II 6.0和JUNGO公司的WinDriver6.03开发工具,完成了系统软硬件集成和协同调试。实际电路调试表明,该架构能够很好的工作,并有效的减小了通信板的面积、简化了外围电路设计,同时也极大地降低了生产成本。
