Description

[0001]
[Industrial applications]
The present invention relates to a plant monitoring device that monitors the status of a plurality of plants using a display device.
[0002]
[Prior art]
Display devices such as CRTs are very utilized in plant monitoring due to the variety and flexibility of information presentation methods, and occupy an important position in plant operation.
[0003]
Taking a CRT as an example, the state of the plant is displayed as a system diagram, and real-time information such as the temperature and pressure of each part of the plant is added to enable visual monitoring.
[0004]
[Problems to be solved by the invention]
However, with the increase in the number of plants and the complexity of the plant structure, it is becoming very inconvenient to monitor a large amount of monitoring information in a limited display area of a CRT. For example, when monitoring a plurality of plants, CRT devices for the number of plants are installed, troublesome operations (screen registration, etc.) are displayed on a split screen, and CRT devices for system diagrams, trends, etc. are provided ( A technique such as that described in Japanese Patent Application No. 58-217007) must be used. In this case, there is a problem that the burden on the operator increases and it becomes difficult to monitor the entire plant with a small number of people.
[0005]
According to the present invention, a method of combining and displaying information of a plurality of plants is simplified, a screen size corresponding to each plant state is provided, and a request function is provided for each divided screen. Accordingly, it is an object of the present invention to enhance operability and monitoring performance and reduce the burden on the operator.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, a function key for monitoring the entire plant is provided, thereby displaying a menu of plant monitoring information, and selecting an item to be monitored from this menu, whereby a plurality of plants using one CRT device can be monitored. Can be monitored (claim 1).
[0007]
In displaying the whole plant monitoring screen, a process for determining the size of each divided screen is provided, and it is possible to display the screens of the plant to be noticed at the time of monitoring in large order.
[0008]
A request function (touch key) is provided on each divided screen, and processing for changing the setting of the request function (touch key) according to the screen size is provided.
[0009]
[Action]
An overall monitoring key is provided on the keyboard, and when this key is pressed, an entire plant monitoring menu is displayed on the screen. By selecting an item to be monitored from this menu, a screen of each plant relating to the selected item is displayed. In addition, a process for determining a screen size corresponding to a plant state is provided, and a plurality of plants are displayed in a large size in order from a screen of a plant of interest.
[0010]
In addition, a request function can be set for each of the divided screens, and the currently displayed screen can be switched to another screen. According to the screen size, a process for setting the number and contents of the request functions is provided to enhance operability.

【Example】
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0012]
FIG. 1 shows an example of the configuration of a display device and a process for implementing the present invention. In this embodiment, a case where the present invention is applied to a combined power generation plant is shown, but the present invention does not depend on a target plant. Information from the sensors of each axis of the combined power generation plant 3 is stored in the plant database 5 for each axis via the process input / output device 4. Here, by requesting the overall monitoring key and the screen type (eg, system diagram, trend, etc.) from the keyboard 2, information on each axis is sent from the plant database to the optimal display processing unit. The optimum display processing unit determines the screen format while referring to the information in the display determination information storage device 7, and outputs this screen information to the display output processing unit 8. A display output process is performed, and a combined display screen is displayed on the overall monitor CRT1.
[0013]
FIG. 2 shows an example of simultaneous display on one CRT of a system diagram for four axes. Here, a display example is shown when the first axis plant is operating and the second, third, and fourth axis plants are out of operation. In this case, since the operator only has to put emphasis on monitoring the first axis plant, the first axis plant system diagram is displayed larger than the other axis plant system diagram in the display screen area. The optimal display processing 6 will be described with reference to FIG. When the general monitoring key is pressed from the keyboard 2, a general monitoring screen menu 11 is displayed as shown in FIG. Select the item to be monitored from the menu 11. Based on this request and the data of the plant database 5, a selection display data creation process 61 is performed. In the selected display data creation processing 61, processing is performed with reference to the information stored in the display determination information storage device 7 based on the input request data and plant data, and a display data set is output. The display determination information storage device 7 stores data such as a screen type, a screen size, a plant state, and a request function. The selection display data creation processing 61 first determines which screen type (system diagram, trend graph, alarm display, logic diagram, etc.) has been selected, and the individual plant states (starting, running, stopped, etc.) in a plurality of plants. judge. Further, it determines the screen size according to the plant state and how much the request function (touch key) 12 of each screen according to the screen size is set. These determination results are output to the screen composition processing 63 as a display data set. Further, the plant data of the plant database 5 is sent to the screen editing process 62 to edit each screen of each plant. With this processing, the screen data set is output to the screen synthesis processing 63. The screen synthesis processing 63 performs processing such as screen combination, size adjustment, request function setting, and the like based on the display data set and the screen data set. Further, output processing is performed, and the requested overall monitoring screen is displayed on the CRT screen 1. The above-described selection display data creation processing 61, screen editing processing 62, and screen synthesis processing 63 are collectively referred to as optimum display processing.
[0014]
FIG. 5 shows an example of a screen change of the divided screen in the overall monitoring screen. This has a request function (touch key) 12 for each divided screen, whereby the screen can be individually changed. However, when the display area is small as in the divided screen A in FIG. 6, the screen is enlarged in consideration of the operability and the monitorability, and then the request function (touch key) 12 appears on the screen. The setting of the request function (touch key) 12 in the split screen is determined by the selection display data creation processing 62 in the optimum display processing 6.

【The invention's effect】
Display devices such as CRTs are frequently used in plant monitoring. However, it is difficult to monitor an enormous number of plant monitoring information in a limited CRT monitoring area, and further improvement is required in the future. Have been. To simply solve this problem, it is effective to increase the number of display devices. However, there are problems such as an increase in cost, an increase in the number of operators, an installation space, and the like. According to the present invention, it is possible to simultaneously display monitoring information of a plurality of plants on a single screen, to select monitoring information for each partial display screen, to display a screen of an optimal size according to a situation, and the like. With this feature, the operability and monitoring performance can be improved, and the effect of efficiently using a limited screen display area can be expected, thereby contributing to the improvement of the man-machine interface.
