摘　　要：针对目前远程控制扩展性弱的现状,设计了一种基于myDAQ的远程多对象控制系统,该系统将NI便携式数据采集设备(myDAQ)上的各种信号源通过模拟开关技术拓展成六路信号,并通过单片机IAP技术实现六路信号之间的切换控制。上位机通过LabVIEW编写制作便于人机交互的图形操作界面,并通过LabVIEW的Web发布技术将前面板发布到网络上。该系统在网络环境下成功实现了利用任意一台PC机对现场六种被控对象随时随地的交互式远程控制,并且通过摄像头实时观看控制现象。该系统已成功应用于iLab实验室的远程网络实验教学中,并且运行可靠稳定。In view of the weak extensibility of current remote control, a remote control system for multi-object is proposed. The signal sources from NI portable data acquisition device （myDAQ） are expanded to six groups of signals based on analog switching technology, and the switching control of the six groups of signals is realized by the IAP technology of the SCM. The graphic operation interface convenient for man-machine interaction is written through LabVIEW by upper computer, and the front panels are released to the network through the Web publishing technology of LabVIEW. The system successfully accom- plish the interactive remote control of six kinds of objects at any time and place through any a PC under the network environ- ment, and you can watch the control phenomena via camera in real-time. The system has been successfully used in the remote network experiment teaching of iLab laboratory, and the operation is reliable and stable.
