At the same time, the system can achieve remote control experiments on the Internet by virtual
laboratory remote client. Because the virtual lab system is based on the virtual experiment server
located at the center of the central server, which is responsible for the management and scheduling of
each experiment module and the field experiment instrument. On the one hand, the system receive the
Web server through the remote client's instructions, and call the relevant experimental module to
experiment and download the experimental parameters; On the other hand, the system collected field
control end of the experimental data through the interface of OPC server DataSocket protocol, and
transmitted in real time to the remote client. The experimental results was shown in Figure 5. The
remote client operating curve and the local end is basically the same, the delay is less than 1s. It is
proved that the virtual network laboratory can achieve the basic goal of the network based remote
experiment.
