Abstract:
This thesis introduces a new approach to the design of bench-top instrument systems, the Virtual Instrument Workstation (VIW). The VIW sets out to produce a much more flexible, modular instrumentation system than conventional designs, and one which is also cost effective. The main thrust of the work is to break down conventional instrument systems into clearly defined hardware and software modules that can then be shared concurrently among a number of Virtual Instruments (VIs). The use of a touch sensitive, window managed, software driven CRT display is central to the concept. This allows the high level of user interaction with the system and multiple VIs to be accomplished with an easy-to-understand front-panel. A special Instrument Bus system is defined to allow the easy production of instrument modules for use in the system. The communications between the instrument modules is unified, such that all data can be passed between all modules. VISYS, a real-time multi-tasking, operating system is developed to provide a software environment for the VIW. This system is UNIX based and, has many real-time extensions. The VIW described has the ability to perform the operation of several separate instruments simultaneously. The range presented in the work includes a Signal Generator, a Digital Multi-Meter, an Oscilloscope and a Component Meter. Both the hardware and software aspects of the VIW are presented in detail.
