When the above-mentioned DCB-O25, which is adapted to monitor the online system information during the working mode, receives the online system accident / fault information, the connection state with the output terminal 28a is automatically changed from the connection state with the output terminal 28a. Operates to switch to a state. The mode switching timing is set within 5 seconds.

Further, the above-mentioned offline DCB-T27
A switch 30 is provided between the IFB-T 28 and the IFB-T 28 as a stopping unit that automatically stops the operation of the DCB-O 25 when the online accident / fault information is received.

Next, in the operation of the above configuration, first, referring to FIG.
The state in the actual operation mode in the online system and the state in the training operation mode in the offline system shown in FIG. 5 will be described. Figure 4 is for online
It is the normal operation state of the actual operation operation mode. In this case,
Online information that does not include accident / failure information is transmitted to the online system, and the DCB-O25 of IFS1 constantly receives the online information to determine whether or not an accident / failure has occurred, and the IFB-O26 sends H
To IS-S9 is sending the display information of the online system.

FIG. 5 shows a training program in an offline system .
Is the state of the work mode, switching to this mode is carried out in the manual operation of the switch 29 and 30 by maintenance personnel Mb. In the training operation mode in the off-line system, the trainer Mc inputs simulated information on an accident / fault to the DCB-T 27 of the IFS 1 via the simulator 28B, as indicated by a dotted arrow in FIG. By doing so, the DCB-T27 receives the simulated system information, determines whether or not an accident / failure has occurred, and
The inference control unit 28A of the IFB-T 28 uses the knowledge / data stored in the knowledge base KB2 / database DB2 on the basis of the above-mentioned simulation information to execute a predetermined inference and sends the result to the HIS-S9. Then, by displaying the inference result of the offline system to the maintenance worker Mb,
Training such as education and training for maintenance personnel Mb is performed.

Training in such an offline system
