Abstract

PROBLEM TO BE SOLVED: To obtain a man-machine interface device which enables an operator to grasp the situation of a plant easily. SOLUTION: A man-machine interface device is equipped with a means 28 for indicating assisting information in case of an accident and a means 29 of managing and indicating an operation manual. When a plant abnormality diagnosing guide means 27 diagnoses an abnormality as an accident in a plant, the means 28 allows an indicator 31 to indicate a plant parameter related to the accident. When a single alarm sounds, the means 29 allows the indicator 31 to indicate a procedure for a countermeasure in response to the alarm. When the means 27 diagnoses an abnormality as an accident in a plant, the means 29 allows the indicator 31 to indicate a procedure for a countermeasure in response to the accident. Therefore, an operator can easily grasp the situation under abnormal conditions in the plant without operating the device and can cope with the situation properly after the accident.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a man-machine interface device for monitoring operation of a nuclear power plant or the like.

[0002]

2. Description of the Related Art FIG. 13 is a block diagram showing a conventional operation monitoring man-machine interface of a plant disclosed in Japanese Patent Publication No. 4-34118. It is a processing unit. 3
Processes the process signal from the process amount detection unit 1,
A monitoring unit for grasping and monitoring the plant comprehensively, 4 is a monitoring unit 3
A display screen creation storage unit that creates, for example, a plurality of screens of screens A to P based on the image signals for each system based on the process signals processed by the processing unit, and stores these. 5 calculates, based on the process signal from the monitoring unit 3, how much the operation state of the plant deviates from the designed operation state, determines the priority of the screens A to P based on the deviation, and determines the display order. The determination unit 6 for outputting a signal outputs the screen A stored in the display screen creation storage unit 4 based on the display order signal.
To a main screen 8 for selecting one of the screens P to P to display the main screen 8 on the CRT display 7.

[0003] A sub-screen display unit 9 creates character information and the like to be displayed next as the main screen 8 on the CRT display 7 based on the display order signal from the determination unit 5 and displays the information on the sub-screen 10.
Reference numeral 11 denotes a screen switching permission switch for outputting a screen switching permission signal to the main screen display unit 6 to switch the main screen 8, and 12 denotes A to P
And a screen switching selection switch that outputs a screen selection signal to the main screen display unit 6 so that the screens A to P specified by the operation unit 13 are displayed as the main screen 8. . FIG. 14 is an explanatory diagram showing the main screen 8 and the sub-screen 10 displayed on the CRT display 7.

Next, the operation will be described. If all the systems in the plant are normal, C
It is displayed as a main screen 8 on the RT display 7. At the same time, character information to be displayed next as the main screen 8 is displayed on the sub-screen 10 according to the display order. Therefore, the operator grasps and monitors the state of the system on the main screen 8 as shown in FIG. 14, and at the same time, determines which screen is displayed next by the sub-screen 10, its priority and contents. You can know. Then, the operator displays the main screen 8
When the status of the system is grasped and monitored by the user, the screen switching permission switch 11 is operated to operate the main screen 8.
Displays the next screen. Further, when an abnormality occurs in a certain system, the operator operates the operation unit 13 related to the abnormality, for example, N of the screen changeover selection switches 12 to display the screen N relating to the abnormality on the main screen. 8 can be displayed.

[0005]

Since the conventional operation monitoring man-machine interface of the plant is configured as described above, the priority of the main screen 8 displayed on the CRT display 7 indicates the abnormal state of the plant. Although it is easy to confirm the time, just prioritizing based on the change in the process amount will cause many alarms like in the case of a plant accident, etc.
When a large number of process quantities fluctuate simultaneously and greatly, there is a problem that effective prioritization cannot be performed. Further, although the main screen 8 displayed on the CRT display 7 is switched according to the priority, in the case of a major accident, the information is narrowed down to a high degree of intensiveness, and after the event has converged, detailed information including management information is displayed. There is a problem that it is not possible to control the display information such as the layering of the information, the display form, and the degree of detail of the information, and it is difficult for the operator to grasp the situation.

Further, in the event of a plant accident, an alarm is issued and an event is determined on the basis of the alarm, a stage in which the state is to be checked preferentially when the plant is stopped, a series of events converge, and an operation procedure The operator had to judge the necessary information by himself and perform the instruction operation in each case, such as in the stage of confirming that there was no failure in the corresponding operation by confirming the follow-up. . For this reason, there is a problem in that information required to be confirmed is appropriately selected and displayed in accordance with the situation, and there is a problem that a burden of information retrieval by a manual instruction operation is large. Furthermore, in the operation procedure manual display device, a computerized procedure manual search and display device is applied, but the procedure is displayed automatically when the procedure is complicated and assistance is required. Information display adapted to the task of the operator in the corresponding operation is not considered, and unnecessary detailed information is displayed, so there were problems such as the number of screen switching times and the burden of instruction operation increased. .

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and has as its object to provide a man-machine interface device that allows an operator to easily grasp the condition of a plant.
