The realization of network virtual electronic laboratory

By integrating network technology, virtual instrument technology, video image network transmission and Web page fusion technology, the network virtual electronic laboratory based on B/S mode was developed. The network structure of the system consists of the Web server, virtual instrument system, the network video monitoring system, the Web database and the remote clients. The key technical problem of remote controlling of laboratory instruments was also settled. Through simply using the standard Internet browser, the long-distance clients can not only watch the real experiments operating and get the testing results within the same Web page, but also control many virtual instruments such as signal generator, digital oscilloscope, the modem and the differentiator. This paper presents the key technology in the system.
