<p>PURPOSE:To reduce the load of an operator and to prevent the generation of misdecision and misoperation by deciding an operation guideline to be led from the cause of generation of multiple accidents in a plant and its state at the time of generating the multiple accidents and extracting and displaying minimum information to be monitored by the operation guideline. CONSTITUTION:When an alarm signal 51 due to abnormality in the plant is inputted to an input device 1, its corresponding alarm window on an alarm display board 2 is lighted and the signal 51 is inputted to a signal input part 11 in a process computer 3 through an interface 4. At the time of deciding a fatal accident based upon decision logic stored in a decision logic storage part 14 after receiving the alarm signal 51, a logical execution part 15 displays an operation guideline to be led in. The operator is only required to correspond to the guideline, and at the time of requesting the minimum information to be required for execution from an I/O device 5, a picture with the most understandable format is formed by a picture formation part 12 and displayed on a CRT 6 through a picture display part 13, so that the generation of misoperation and misdecision can be prevented.</p> |
