Sandia National Laboratories has fielded an extensive instrumentation system to collect and display data from large-scale oil-shale retorts. A great number of process and thermal measurements are recorded by the data-collection computer during these retort operations. Real-time access to this information by operators and analysts, who are at remote locations, is extremely beneficial. To provide access to a large number of displays showing data from an oil-shale retort, while minimizing system resource requirements, a menu-driven interactive video monitor system has been developed. This system has four independent video-display monitors multiplexed into one asynchronous serial computer output port and four telephone-type push button keypads multiplexed into one parallel input port. A user selects, from a menu, the information to be displayed on his monitor by pressing the keypad button corresponding to the desired menu item. The system decodes the station address and menu selection, assigns resources and executes the programs required to display the requested information on that monitor. Menu items can be easily added or deleted to suit the changing conditions making the system very flexible and adaptable to a wide variety of situations.
