Abstract:
New Web-based monitoring and control system applications have been developed to allow remote control of equipments. Although interesting and useful, such applications present hidden costs related to software development tools, annual software licensing, regular maintenance and upgrades. This paper presents an application tool for controlling instruments over the Web developed using open code resource, such as Linux, JAVA and CamServ. The application shows a potential use for laboratories dealing with different types of equipment conformance testing. The developed tool allows access to the instrument’s screen through a video streaming process, an alternative towards similar application, in which data is first acquired and then plotted using graphical tools. First tests over a 10 Mbps LAN Network and 1 Gbps Ethernet Inter-Universities Network evaluated latency times and the video quality versus video signal acquisition system. Specification and development issues are described, as well
testing and validation schemes of the developed application.
