This knowledge is then encoded in the form of rules, which are executed by the expert system each time a new piece of sensor data becomes available. Page 7 Figure 4 – Overall Condition Summary Screen Capture User Interface The user Interface provides the point of principal human interaction with the system, and was therefore designed and implemented to relate sufficient levels of information without being cumbersome or overbearing (Figure 6). The goal is to integrate the HydroX user interface as much as possible into the normal operator’s display. Providing an alarm output from HydroX to the plant SCADA ensures that HydroX notifications are received by the operator in a fashion similar to other alarms. The user interface uses a client/server architecture, making it possible to have multiple user interfaces operating at one time. This allows both operations and maintenance . . .
