2. Description of the Related Art FIG. 6 is a block diagram showing a conventional plant monitoring system disclosed in, for example, Japanese Patent Application Laid-Open No. 7-98642. In FIG. Input data determining means 5 for outputting is a hierarchical menu display means for displaying the contents of the hierarchical menu table 8 on the display device 2, and 7 is a task generating means for generating task information from the task information storage table 9 based on the notification data. , The virtual screen display means 10 is notified, and when the task information is generated, the history menu table 11
The generated task information is stored, the corresponding task information is read in response to the selection request, the virtual screen display means 10 is notified, and the selected screen is displayed on the display device 2. 10
Is a virtual screen display means for creating and storing virtual screen data and displaying it on the display device 2 by a plurality of screen display means 6, and 12 is a display request for displaying the contents of a history menu storage table storing history menus on the display device 2. It is a history menu display means for displaying.

Next, the operation will be described. The input data judgment means 4 judges the content of the request from the input device 3 and outputs the notification data, the hierarchical menu display means 5 displays the contents of the hierarchical menu table 8 on the display device 2, and the virtual screen display means 10 displays the virtual data. The screen data is created and stored and displayed on the display device 2 by the plurality of screen display means 6. Next, the history menu display means 12 displays the contents of the history menu storage table for storing the history menu by the display device 2 according to a display request.
The task generation means 7 generates task information from the task information storage table 9 based on the notification data and notifies the virtual screen display means 10 of the task information. When the task information is generated, the task generation means 7 generates it in the history menu table 11. The task information is stored, the corresponding task information is read out in response to the selection request, the virtual screen display means 10 is notified, and the selected screen is displayed on the display device 2.

At this time, the displayed contents are stored in the history menu table 11, and if it is desired to display the contents displayed in the past, the contents can be displayed by selecting from the history menu display means 12, and the past contents can be displayed. If you want to check the operation history of, you can do so by displaying this history menu. As described above, storing the operation history performed by the operator in the past is very effective when it is necessary to analyze the operator's operation. Therefore, each plant monitoring control device can independently operate its own device. It kept the operation history of.

[0005]

Since the conventional plant monitoring system and the operation history method of this plant monitoring system are configured as described above, a large screen device is connected to the network and a plant monitoring control device group is formed. When each operation of this large screen device is performed, there is a problem that it is not possible to clearly distinguish and display the operation history of its own device or the operation history of the large screen device in each plant monitoring control device. It was

The present invention has been made to solve the above problems, and clearly distinguishes between the operation history of its own device and the operation history of a large-screen monitoring control device in each plant monitoring control device. , A plant monitoring system that can be displayed and an operation history method of this plant monitoring system are obtained.

[0007]

A plant monitoring system according to the present invention, in a plant monitoring control device, controls operation contents of the plant monitoring control device and stores the operation contents of the plant monitoring control device in a plant monitoring storage table. Then, the operation contents of the large screen monitoring control device are stored in the large screen monitoring storage table, and the contents of the plant monitoring storage table and the large screen monitoring storage table are displayed on the operation history display device,
