问题:
我能否通过笔记本电脑对PXI系统进行远程控制?
解答:
您可以借助位于以太网上的嵌入式控制器通过很多方法从任何计算机,也包括笔记本电脑,对PXI系统进行远程控制。
所有用笔记本电脑对PXI系统进行直接控制的方案都具有相同的硬件配置。嵌入式控制器,典型的运行在Windows或者LabVIEW RT之下,用来对PXI机箱进行控制。然后您可以通过一根直连以太网线直接将您的笔记本电脑和PXI嵌入式控制器相连。直连以太网线允许在您的笔记本电脑和PXI嵌入式控制器之间进行直接的对等网络通信,以下的配置方法能让您对PXI系统完全的控制。
方法1:使用PXI嵌入式控制器和LabVIEW实施模块(RT)
美国国家仪器提供多种可以运行在LabVIEW RT下的PXI嵌入式控制器。通过LabVIEW RT,您可以从上位机(例如,笔记本电脑)将LabVIEW程序下载到PXI嵌入式控制器中。然后,你可以对嵌入式控制器进行配置,使其一启动就开始运行RT程序。您可以使用笔记本电脑作为用户界面控制和配置变化。
方法2:使用Windows XP远程桌面技术
微软的Windows XP在Windows操作系统中采用了远程网络控制技术。使用Windows XP远程桌面,您可以通过经网络传送的Windows桌面用户接口远程登录到计算机中。欲对PXI嵌入式控制器进行配置,您必须首先将控制器配置成“无头”操作,也就是说,您必须将控制器配置成在没有键盘、显示器以及鼠标的情况下, 可以无错的启动。您可以通过在系统启动时进入启动界面(BIOS)然后在系统启动时关闭键盘错误来轻松和快捷的对控制器启动选项进行设置。然后,配置Windows XP远程桌面。欲了解更多关于将系统配置为使用XP远程桌面的内容,请参照如下链接的知识库 2Y5FNQOK 以及
