Computer assisted execution of process operating procedures.

摘要

A computer-assisted apparatus aids an operator in proceeding step-by-step through procedures for a complex process facility which has a multiplicity of sensors generating process parameter signals. At each step, monitored parameter signals are used to evaluate relevant plant status and to recommend action to be taken. The status and recommended action are presented to the operator on a display device together with prompts for generating appropriate responses. The complete display picture including operator responses, and other plant conditions monitored in parallel with the current step, are logged for later review. An on-line review feature permits review of plant conditions and operator actions while the operator continues to execute the procedure.
