Predict the time of occurrence of faults a to 1b and predict the predicted equipment 1
Information on the history curve of the value of the telemeter data of the corresponding equipment is output to the equipment deterioration information display control unit 13 as equipment deterioration information together with the information on the occurrence times of the faults a to 1b. The equipment deterioration information display control unit 13 displays the equipment deterioration information output from the failure occurrence time prediction unit 12 in a predetermined format as shown in FIG. 2 as an example.
To be displayed.

FIG. 2 is an explanatory diagram showing an example of display of equipment deterioration information of the monitoring system according to the present embodiment. In FIG. 2, the vertical axis indicates the value of data indicating the degree of deterioration of a specific facility in which the degree of deterioration in the facilities 1 a to 1 b has deteriorated,
The horizontal axis is a value indicating the passage of time. The elapsed time period on the horizontal axis goes back to the past from the time of display and stores the value of the telemeter data in the previously determined period in the storage unit 10.
The equipment deterioration information display control unit 13 reads out the
Pass to. The storage unit 10 deletes old telemeter data values that have passed the predetermined time period.
As an example of the display of the equipment deterioration information shown in FIG. 2, a case where the deterioration degree of the equipment 1a is deteriorated will be described. Level, but with the lapse of time, the value of the telemeter data gradually decreased as the equipment gradually deteriorated.After a certain time, the degree of deterioration rapidly increased, and finally after the failure occurrence prediction information display level had passed, The state in which a failure occurrence level is reached is shown. The point at which the history curve of the value of the telemeter data intersects the failure occurrence level is the predicted failure occurrence time. The equipment deterioration information display control unit 13 includes a prediction part of the history curve of the data value of the equipment 1a and the equipment 1 so that the operator can easily grasp the situation.
The indication of the time of occurrence of the fault a is blinking. In addition, the equipment deterioration information display control unit 13 includes, in addition to the information shown in FIG.
Message information, such as the name of the corresponding equipment and a method for dealing with a predicted occurrence of a failure, is displayed on the display screen of the display unit 6.

The display unit 6 also displays fault information transmitted from the equipment fault notification device 2 when a fault occurs in the equipment 1a to 1b, so that the above-described equipment deterioration information is displayed. When the failure information is transmitted due to the occurrence of a failure in the equipment 1a to 1b, the main control unit 14 notified from the alarm information display control unit 8 that the failure information has been transmitted is controlled by the equipment deterioration information display control. This is notified to the unit 13 to delete the display of the equipment deterioration information, and instructs the alarm information display control unit 8 to display the failure information on the display unit 6. After confirming the fault information displayed on the display unit 6, the operator can re-read the equipment deterioration information deleted from the display unit 6 by operating the operation input keys (not shown) of the display unit 6 as necessary. A control input for instructing display can be made.
