摘要： An object of the invention is to provide a system for assisting operation at the time of a plant accident, which, even if a device malfunctions at the time of the plant accident, can determine normality of a sensor without being influenced by the malfunction. A system for assisting operation at the time of a plant accident, includes: a phenomenon identification apparatus for identifying a state of a plant; a plant behavior analysis apparatus for predicting progress of a process state after a phenomenon occurs by using at least a phenomenon identification result as an initial condition of plant behavior analysis; and a sensor normality determination apparatus for determining normality of a sensor by comparing a result of prediction of the progress of the process state which is output from the plant behavior analysis apparatus with a sensor signal.

摘要： To eliminate or reduce stress for an operator who operates an operation panel. A touch panel-type operation panel includes a display with touch panel including an image display surface for displaying an operation part and a control device. The display with touch panel detects approach of an operation finger to the operation part and the position of the operation part and outputs signals of the detected approach of the operation finger and the detected position. The control device predicts and analyzes, in response to an input of the signals of the approach of the operation finger and the position, a state of a control target by operation corresponding to the operation part with reference to state data of the control target, determines appropriateness of the predicted and analyzed operation, and outputs a result of the determination.
