基于FPGA与Flex的远程虚拟示波器的研究
evelopment of remote virtual oscilloscope Based on FPGA and Flex
为了满足虚拟实验系统的建设需要,应用富客户端(RIA)成熟技术之一Flex技术设计虚拟仪器,改进了虚拟仪器开发方法和远程数据交互方式。系统中通过FPGA实现虚拟示波器的数据产生、采集,使用Flex实现虚拟仪器的界面设计和数据显示,并通过J2EE服务器将虚拟仪器部分和硬件数据部分相集成。在Flex设计的虚拟仪器部分通过Http协议发送数据采集、调整指令给Web服务器,Web服务器接收到不同指令解析后通过Socket方式发送给ARM服务器,采集FPGA中的实时数据流以Soap方式回传给Web服务器进行显示,实现了虚拟仪器的远程化和数据的实时性。
o meet the construction of the Virtual Experimental system, Flex ,the rich client side technology (RIA) ,is used to design virtual instruments. In this way, it improves the design methods and remote data interactively. In the system, the FPGAgenerate and gathers the data for the virtual oscilloscope, use Flex to design the interface and data display, J2EE server integrates the virtual instrument and hardwaredata portion. The virtual send dataacquisitionor adjustinginstructions to Web server in the Http protocol. The server analyzes the receivesinstructions and send them to the ARM server in Socket. The real-time data stream, provided by the FPGA ,sent back to the Web server to display in the Soap way. It realize the remote virtual instrument and real-time data interaction.
