The monitoring data creating means 50 creates the plant monitoring data as shown in FIG. 24 based on the priority alarm data from the image extraction determining means 49, creates the same data as the plant monitoring output means 17, and sends it to the plant monitoring data input means 18. Notice.

According to the fifth embodiment, since the monitoring panel information displayed on the monitoring panel 13 of the plant is input by the video signal, a large amount of process inputs are input to the monitoring panel information and the plant centralized monitoring apparatus is input. Since it is not necessary to send the signal to the H. 12, the hardware for inputting the process signal can be reduced.

Next explained is the sixth embodiment of the invention. FIG. 25 is a block configuration diagram of a plant monitoring apparatus according to the sixth embodiment of the present invention. The sixth embodiment is different from the fifth embodiment shown in FIG. 20 in that an alarm reset data is created when an alarm reset command is input from the input / output device 21 to the monitoring panel 13 of the plant. The reset data processing means 32 is connected to the plant centralized monitoring device 1
2 and the alarm reset data from the alarm reset data processing means 32 is input, the monitoring board 13 of the plant
Alarm reset means 3 for outputting an alarm reset signal to
3 is provided in each of the plant individual monitoring devices 11a to 11n. The same elements as those of the fifth embodiment shown in FIG. 5 are designated by the same reference numerals, and duplicate description will be omitted.

The image input means 45 is the monitoring board 1 of the plant.
The display state from 3 is photographed, the video data is converted into digital data, and the encoded input means 46 is notified. The encoding input means 46 converts the digital data notified from the video input means 45 into image compression data such as MPEG4 and notifies the code data conversion means 47.

Further, the operator confirms the alarm state with the input / output device 21, and performs the alarm reset operation with the input / output device 21 in order to reset the alarm of the monitoring panel 13 of the plant and stop the buzzer. The input / output device 21 notifies the alarm reset data processing means 32 of the alarm reset operation. The alarm reset data processing means 32 creates alarm reset data and outputs the reset data to the alarm reset means 33 of the corresponding plant individual monitoring device 11i. The alarm reset means 33 outputs an alarm reset signal to the alarm unit 14. The alarm unit 14 stops the buzzer or stops blinking the alarm display on the monitoring panel 13 based on the input alarm reset signal.

According to the sixth embodiment, the information displayed on the monitoring board 13 of the plant can be monitored by alarm without inputting a large amount of process inputs. Also, in the plant alarm monitoring, it is possible to perform detailed monitoring such as stopping the buzzer and stopping the blinking of the alarm display, and turning off and turning on the display again, and as a result, it is possible to improve the monitoring accuracy. it can

As described above, according to the present invention, the monitoring panel information displayed on the monitoring panels of a plurality of independent plants is input to the plant centralized monitoring device, and the alarm priority is given based on the monitoring panel information. Since the data corresponding to the priority is output to the input / output device with a certain degree, a plurality of plants can be appropriately monitored. As a result, when monitoring a plurality of plants in a concentrated manner, it is not necessary to attach an operator to each of the plurality of plants, so that the cost can be reduced.
