In the example shown in FIG. 6, a scale indicating the life is put on a number line 601 for each of the devices A to C, and as the life of the device is shortened, a symbol mark 602 imitating the device is changed to a numerical value of the scale. It is designed to move in the direction in which it decreases. That is, the scale of the number line 601 in the symbol mark 602 indicates the life of the device. Further, a character string life display 6 indicating the life of the device is displayed above the time table.

Therefore, both the position of the symbol mark 602 on the timetable and the character string life display 603 make it possible to grasp at a glance the life of each of the devices A to C. It is possible to accurately grasp the time for replacement / replacement. In addition, when the horizontal axis in FIG. 6 is displayed as the recommended maintenance time, it is possible to grasp at a glance the appropriate maintenance time of the equipment, so that it is possible to grasp the appropriate maintenance time even without a skilled person. .

In FIG. 6, the display format is such that the symbol mark indicating the device is moved on the time table. However, as a modified example, only the symbol mark can be displayed without using the time table. . In this case, it is possible to simply reduce the size of the symbol mark as the remaining life and the period until the maintenance period become shorter, but the device image is completed in the initial stage, and the period until the remaining life and the maintenance period become shorter. Accordingly, a display format in which the size is reduced while the device image is deformed by being cut out may be considered. Further, it is also conceivable to combine a change in the symbol mark and a change in the display color with the time table.
For example, the display color of the symbol mark in FIG. 6 may be changed as the life is shortened.

On the other hand, after the maintenance of the equipment, the operation state quantity of the equipment is re-integrated by reflecting the state data of the equipment obtained at the time of the maintenance, and life / maintenance time prediction data is generated in accordance with the re-integration result. It is desirable to do so. This makes it possible to reflect the actual equipment status data for each maintenance to the predicted value of the remaining life of the equipment and the appropriate maintenance time, thereby improving the reliability of the prediction data of the remaining life of the equipment and the appropriate maintenance time. Can be.
