Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant monitoring device for monitoring the states of a plurality of plants with a display device.

[0002]

2. Description of the Related 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.

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]

However, as the number of plants increases and the plant structure becomes complicated, it is becoming very inconvenient to monitor a lot of monitoring information in a limited CRT display area. For example, when monitoring a plurality of plants, install CRT devices for the number of plants, display troublesome operations (screen registration, etc.) on a split screen, and provide type CRT devices for system diagrams, trends, etc. Sho 58-217007
No.) must be used. in this case,
There is a problem that the burden on operators increases and it becomes difficult to monitor the entire plant with a small number of people.

In the present invention, the method of combining and displaying the information of a plurality of plants is simplified, the screen size corresponding to each plant state is provided, and the request function is provided for each divided screen. Thus, the object of the present invention is to improve the operability and the monitorability and reduce the burden on the operator.

[0006]

In order to achieve the above object, a function key for monitoring the entire plant is provided to display a menu of plant monitoring information.
By selecting an item to be monitored from this menu, it is possible to monitor a plurality of plants with one CRT device (claim 1).

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 which should be noted at the time of monitoring in large order (claim 2).

A request function (touch key) is provided on each divided screen, and a process for changing the setting of the request function (touch key) depending on the screen size is provided.

[0009]

The whole monitoring key is provided on the keyboard, and when this key is pressed, the whole plant monitoring menu is displayed on the screen. By selecting the item to be monitored from this menu, the screen of each plant regarding the selected item is displayed. In addition, a process for determining the screen size corresponding to the plant state is provided so that the screens of the plants of interest among the plurality of plants are displayed in large order.

Further, it is possible to set a request function for each divided screen and switch the screen currently displayed individually to another screen. The operability is enhanced by providing a process for setting the number and contents of request functions according to the screen size.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an example of the configuration of a display device and processing for carrying out the present invention. Although the present embodiment shows the case of application to a combined power generation plant, the present invention does not depend on the 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, from the keyboard 2, the whole monitoring key and screen type
By requesting (example: system diagram, trend, etc.), information on each axis is sent from the plant database to the optimum 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. Display output processing is performed, and a composite display screen is displayed on the overall monitoring CRT 1.

FIG. 2 shows an example of a system diagram for four axes which is simultaneously displayed on one CRT. Here, it is a display example when the first axis plant is operating and the second, third, and fourth axis plants are idle. In this case, since the operator may focus 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 optimum display process 6 will be described with reference to FIG. Keyboard 2
When the overall monitoring key is pressed further, the overall monitoring screen menu 11 is displayed as shown in FIG. From the menu 11, select the item for which you want to perform overall monitoring. A selection display data creation process 61 is performed based on this request and the data in the plant database 5. Selection display data creation processing 61
Then, based on the input request data and plant data, the information stored in the display determination information storage device 7 is referred to, the processing is performed, and the display data set is output. The display determination information storage device 7 stores data such as screen type, screen size, plant state, request function, and the like. In the selection display data creation processing 61, first, which screen type (system diagram, trend graph, alarm display, logic diagram, etc.)
Is selected, and the individual plant states (starting, operating, stopping, etc.) in a plurality of plants are determined. Further, it is determined how much the screen size according to the plant state and the request function (touch key) 12 of each screen according to this screen size should be set. These determination results are output to the screen compositing process 63 as a display data set. Further, the plant data in the plant database 5 is sent to the screen editing process 62 to edit each screen of each plant. By this processing, the screen data set is output to the screen compositing processing 63. The screen synthesis processing 63 performs processing such as screen combination, size adjustment, and request function setting 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 optimum display process is a combination of the selection display data creation process 61, the screen edit process 62, and the screen synthesis process 63 described above.

FIG. 5 shows a screen change example of a split screen in the whole monitor screen. This has a request function (touch key) 12 for each divided screen, so that the screen can be individually changed. However, when the display area is small like the split screen A in FIG. 6, the request function (touch key) 1 is used after the screen is enlarged in consideration of operability and monitorability.
2 should appear in the screen. Whether or not the request function (touch key) 12 in the split screen is set is determined by the selection display data creation process 62 in the optimum display process 6.

Although display devices such as CRTs are frequently utilized in plant monitoring, it is difficult to monitor a huge amount of plant monitoring information in a limited CRT monitoring area. Further improvement is required. In order to simply solve this problem, it is effective to increase the number of display devices, but there are problems such as an increase in cost, the number of operators, and installation space. INDUSTRIAL APPLICABILITY According to the present invention, it is possible to simultaneously display the monitoring information of a plurality of plants on one screen, select the monitoring information for each partial display screen, and display the screen of the optimum size according to the situation. Has characteristics,
As a result, operability and monitorability can be improved, and the effect of efficiently using the limited screen display area can be expected, which contributes to the improvement of the man-machine interface.
