摘要:
A visual display system providing an operator simultaneous descriptions of the states of many cooperating sub-processes working on a task and residing in various instruments in a distributed system. A server process is connected to receive and translate status signals from the sub-processes into a standardized language. The translated signals are interpreted by a screen manipulation program. A monitor, connected to the server process, displays the interpreted signals to show the states of the sub-processes. The visual indication on the monitor includes a plurality of representations of indicator lights. Each indicator light indicates the state of one of the sub-processes. Next to each indicator light is an identifier which identifies the sub-process represented by the indicator light. The visual indication also includes two types of meters. One type of meter indicates the speed of one of the sub-processes and the other indicates the amount of data used at any given time by one of the sub-processes. Finally, a picture of each of the operators using the system is also included in the indication. In one embodiment, the present invention is implemented to monitor a rule-based programming environment using the X Window System.
