Virtual Laboratory is the new concept in the field of Control & Measurement as network technology development, it is used in many university and institute nowadays. It is possible to control and measure the instrument in anywhere, anytime by the use of Virtual Laboratory and we can raise the efficiency of experiment. In this paper, we review the concept and necessity of Virtual Laboratory at first and discuss about how we can implement Virtual Laboratory. Then we design framework of Client-Server based Virtual Laboratory fur operating of remote instrument through network, and finally we suggest system model of Virtual Laboratory capable of controlling & monitoring of instrument.

In this paper we have developed an image security system based on Internet Web in order to overcome the problem of existing systems that use the dedicated network. The developed system resolves the safety problem of the centralized control model by adapting the distributed control model based on Web, and has the functions of remote control and automatic monitoring for grouped multiple sites on remote Web browser. And the system can operate various computers or operating system because it' s operating software was designed by the concepts of Java Virtual Machine and Virtual Instrument. Also, our system has not need of additional cost for network construction by using Internet and can greatly improve the managemental efficiency of system because the maintenance and publishing of software updates can be performed through Web Server.
