PROBLEM TO BE SOLVED: To provide a monitoring device which enables an operator to appropriately cope with abnormality.SOLUTION: An estimation unit 34 creates time-series data of physical quantity including estimated values of future physical quantity on the basis of physical quantity measured by a sensor. A time calculation unit 36 calculates an estimation time required of the physical quantity to reach a first threshold on the basis of the time-series data. When the estimation time required of the physical quantity to reach the first threshold becomes shorter than a predetermined time, an output unit 38 outputs the estimation time and a trend graph which represents the time-series data in graph as a warning. Thus, it is possible to prevent an operator from missing the warning and enable the operator to composedly perform processing for resolving abnormality, and the operator can appropriately cope with abnormality. |
