Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant monitoring control device for centrally monitoring and controlling a plant by operating the operation console while monitoring the plant state on the screen of a display device of the operation console. Relates to a plant monitoring control device that displays an operating procedure to be executed at that time according to each operating stage, a screen corresponding to the operating procedure, operation switches, process state data, and the like.

[0002]

2. Description of the Related Art In a conventional plant, a large number of control panels having a large number of hardware operation tools connected to the plant control equipment and instruments such as meters and recorders are arranged in a control room. The plant was monitored and controlled by monitoring the instruments with the or by operating the hardware controls.

On the other hand, in recent years, due to a demand for centrally monitoring and controlling the plant, the operation and monitoring of the plant are performed by an extremely small number of operation consoles equipped with a display device such as a CRT, with almost no hardware operation tools. The method of operating (hereinafter referred to as "panelless instrumentation control method") is becoming mainstream.

This panelless instrumentation control system replaces a large number of conventional control panels and displays all information necessary for plant monitoring by a display device of a single operation console, and An operation switch (soft switch or soft key for hardware operation switch) is displayed on the screen, and this is operated by input means provided in the same operation console to monitor and control the plant. .

In this panelless instrumentation control system, since the information that can be displayed on the display device at one time is actually limited, the plant is divided into a large number of parts or systems, and the parts specified by the operator are designated. Alternatively, the control was performed by displaying each system.

FIG. 9 exemplifies one screen of the display device of the conventional panelless instrumentation control system. This screen graphically displays a part of the system of the chemical plant in a simplified manner. The system corresponding to this screen is three vessels V10, V20, V30 and six pumps P1020,
P2020, P3020, P1010, P2010, P
3010 and. As shown in this screen, the liquid levels and densities of the vessels V10, V20, and V30 are displayed so that they can be monitored by digital numerical values. Further, starting / stopping of the pumps P1020, ..., P3010 can be operated on the screen. For example, when operating the pump P3020 on the screen, a symbol of the pump P3020 to be operated is searched for on the screen and touched. By doing so, the operation switch window 21 of the pump P3020 is displayed, and the color of the symbol of the pump P3020 changes to indicate that it has been touched or blinks to indicate that this device has been touched.

Next, by touching the operation switch corresponding to the operation contents such as "start" and "stop" in the operation switch window 21 of the pump P3020, the pump P3020 is started or stopped in the actual plant. . In this case, a switch such as "confirmation" is provided from the viewpoint of preventing erroneous operation, and this "confirmation" is performed before the actual operation is performed.
It is also possible to request a switch.

When the plant is operated by the panelless instrumentation control system, the operator confirms the operation procedure in each operation mode by the operation manual, and displays the screen necessary for executing this operation procedure on the operation console. The operation of the plant as described above is executed on the screen by calling on the device, and when one operation procedure is completed, the screen of the operation procedure to be executed next is switched to and the operation of the plant is performed.

In order to switch the operating screen, a soft key 22 for selecting a screen is displayed on a part of the normal screen (lower left corner of the screen in the example of FIG. 9). The operator updates the screen by selecting and touching the soft key 22 for selecting the screen when one operation procedure is completed or when necessary.

The flow of processing in this case is shown in FIG.

In FIG. 8, the process up to displaying the screen, the contents of the driving procedure, and the operation switches is the same as that in FIG. 4, so its illustration is omitted. In the figure, the "type" of the operating procedure
The process is divided depending on whether the operation is confirmed. In the operation procedure in which the “type” is the operation, the touch operation by the operator is input in step 414, and based on the touch operation, the operation is performed via the process input / output device 3 in step 416. Is executed, and immediately after that, it is determined in step 417 whether or not all the operating procedures in the operating procedure file have been executed. If all the operating procedures in the operating procedure file have been completed, the processing is terminated, and if not Automatically shifts to the next operating procedure.

On the other hand, when the "type" is the confirmation operation procedure, the process data to be confirmed in step 418 is compared with the confirmation condition stored in advance in the apparatus. If the confirmation condition is not satisfied, the process proceeds to step 417. If not satisfied, check again.

For example, when the operating procedure is "to confirm that the liquid level of the vessel V30 is reduced by the LR30", the change rate X of the vessel V30 is calculated, and if X <0, the confirmation condition is satisfied. If it is determined and the operation procedure is automatically shifted to the next, and if X> 0, it is determined that the confirmation condition is not satisfied, and the confirmation is performed again.

By doing so, the operator can automatically move to the next operating procedure by executing the operating procedure to be executed, and in the case of simply confirming the process data, entrust the confirming work to the computer 5. You can
