Abstract: In recent years, there has been a surge of interest in the development of Information and Communication Technologies (ICT), especially in the realm of education. A large portion of current ICT work focuses on remote control devices that use HTTP browsers. This paper presents the phases to develop a system that allows multiple users the access to a multiple real electronic circuits using any HTTP browser. With this aim, specific hardware and software have been designed and incorporated to a server-computer which includes a data acquisition card. The novel feature of this work is that the user has in a unique environment with the descriptions of the circuits to study, the possibility to work with real measurements and the necessary laboratory instruments to analyze the circuit signals. The prototype employed analyzes basic analog electronic circuits in order to check out the practical viability of this type of remote control system. Once functionality is demonstrated!
, the prototype can be used as an applicable model for remote controls in any type of real system. The communication protocols, control programs and user interfaces that allow the data transmission and the hardware access have been programmed using Virtual Instruments (VI) designed with LabViewâ – Laboratory Virtual Instrument Engineering Workbench. LabViewâ is a graphical programming language widely adopted throughout industry, academia, and research laboratories as the standard for data acquisition and instrument control software. The front panel of the VIs that guides the user through the system is embebed in his or her web browser like an ActiveX Control. In addition, the user has the possibility to pass information from the HTML browser to the application in the Server in order to study the behaviour of the composed circuits.
Keywords: WWW, remote control, Internet, interface, Virtual Instrument, HTTP.
