Description

Description: TECHNICAL FIELD The present invention relates to a process operation monitoring display device for performing process operation monitoring using a CRT display device.

[Conventional technology]

CRT display devices are used to monitor the operation of thermal power generation processes and nuclear power generation processes. In order to monitor the operation of a process using a CRT display device, it is necessary to simultaneously display a process operation diagram and process detailed information on the CRT display surface. Simultaneous display of different information on a CRT display device during process operation monitoring is disclosed in, for example, JP-A-57-152011.
It is publicly known in, for example, Japanese Patent Publication. However, conventionally, the display area on the CRT display surface is fixed to display different information.

[Problems to be solved by the invention]

Since the display area on the CRT display is fixed, the amount of information in the process diagram is limited. For this reason, the process diagram on one screen becomes a fixed area, and the process may be displayed only partially, and necessary information may not be displayed. Therefore, it is often inconvenient for the operator to select information, and there is a drawback in that the visibility is poor.

An object of the present invention is to provide a process operation monitoring display device which has excellent visibility and can improve the process operation monitoring performance.

[Means for solving problems]

The display surface of the CRT display device is divided into some process operation diagrams and display areas for detailed process information in advance. The controller for monitoring operation searches the display area where important information for monitoring operation is not displayed when a request to display the process operation diagram or process detailed information is made, and displays the process operation diagram and process detailed information in this display area. To do.

[Action]

The display area of the process operation diagram and detailed process information displayed on the CRT display is variable. Therefore, the monitoring operation diagram and process detailed information can be selected and displayed in the display area without erasing the part where the selected operation end of the system diagram is displayed, and the operation end can be selected arbitrarily. A process operation diagram and process detailed information can be displayed. Therefore, the process operation can be optimized and the operation monitoring performance can be improved.

A touch screen 1A which is an input device is attached to the CRT 1 which is a display device. The operation input from the touch screen 1A is received by the touch screen control unit 42 and sent to the operation analysis processing unit 44. Similarly, an operation input from the keyboard 2 is also received by the keyboard control unit 43 and sent to the operation analysis processing unit 44. The operation analysis processing unit 44 analyzes the input operation and outputs information for CRT display control to the CRT control unit 41.
And the process control operation signal is sent to the process operation output unit 45 to be converted into a control signal and sent from the transmission control unit 47 to the dataway 5.

On the other hand, the plant process data received from the dataway 5 to the transmission control unit 47 is edited in the process input processing 46. In the CRT control unit 41, the CRT sent from the operation analysis unit 44
This process data is displayed on CRT1 based on the control information.

FIG. 5 shows a processing flow of the operation analysis processing unit 44. First,
In step S1, it is determined whether the operation content from the touch screen 1A or the input device of the keyboard 2 is an operation end operation or an operation end selection. Step S2 for operation end operation
The contents of the operation are analyzed by, the operation command is generated in step S3, and the operation signal for process control is output. On the other hand, if it is determined in step S1 that the operation end is selected, the operation content is analyzed in step S4. In step S5, the display position of the information for the operating end selected in step S4 is specified by referring to the display information management table, and in step S6 the process operation diagram corresponding to the operating end and the display information necessary for displaying the process detailed information are displayed. A specification is generated and the display position information and the display specification information are sent to the CRT control unit 41 as display control information.

FIG. 6 shows an example of the display information management table. A screen number is attached to the display screen, and an operation number is attached to each operating end. In the display management table 4440, the operation end number included in the corresponding screen for each screen, the operation part for process control when the operation end is selected, and one of a plurality of divided areas on the CRT for displaying process detailed information are displayed. As a preliminary setting. Of course, this display area is set by selecting another display area in which the portion displaying the operation end is not erased.

According to the above, the display form of the process operation diagram of the specific operation end and the process detailed information display from the system diagram (corresponding to FIG. 2) is shown in FIGS. 7 to 8.

FIG. 7 shows the touch screen 1A with the operating end 111 from the system diagram 11.
An example is shown in which the detailed information display unit 100, such as process data regarding the operating end 111, is displayed by selecting. The detailed information display unit 100 displays the set value P _S , the process amount Po, and the operation value Pi.

In the present embodiment, the process operation diagram and the detailed information display section are displayed on the rightmost side of the screen (the information display area 10 in FIG. 3).
08) as a general rule, when operating end 113 is selected, operating end 111
This information is displayed in the same way as when is selected.

FIG. 8 shows an example in which the operation end 112 is selected from the touch screen from the system diagram 11 and a process operation diagram corresponding to the operation end 112 is displayed.

At this time, as shown in FIG. 7, when the process operation diagram of the operating end 112 is displayed at the same display position as the detailed information display portion for the operating end 111, the portion of the system diagram showing the selected operating end is deleted. become. However, by using the display information management table described above, a display position is selected in a portion not related to the operating end 112, effective use of the screen on the display device, and a plant system diagram and process detailed information 110 that does not erase the operating end 112. The composite display makes it easy for the operator to grasp the position of the equipment to be operated and enables the operator to carry out appropriate driving operations.
