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 displaying the state of a plant such as a nuclear power plant and touching the screen of the display device for operation monitoring and control.

[0002]

2. Description of the Related Art For example, FIG.
Is a plant operation monitoring device for performing a plant operation operation by a conventional touch operation disclosed in Japanese Patent Publication No. 1,1 '.
Is a CRT, 2, 2'is a touch device, 3, 3'is a touch controller, 4 is a CRT control computer (CRT
Processor, 6 is a plant computer (control device).

Next, the operation will be described. CRT1,
Reference numeral 1'displays a plant state and an operation device related to the operation. This display is, for example, a screen in which valves, pumps, pump motors, etc. are represented in a system diagram, and displayed by analog or digital values such as valve opening, pump flow rate, pump motor ON / OFF. The operator touches the displayed position of the desired operating device to carry out the driving operation. The touch operation of the operator is transmitted to the touch controllers 3 and 3 ′ via the touch devices 2 and 2 ′, and the touch controllers 3 and 3 ′ detect the position touched by the operator. The detected coordinate position is collated with the screen information (background image information) which is transmitted to the CRT control computer (CRT processor) 4 and displayed, and the screen (background image) displayed at the touched coordinate position is operated. If it is a switch area, it is converted into control information related to the operation and transmitted to the plant computer (control device) 6, and the plant computer (control device) 6 executes the control operation.

On the other hand, if the screen (background image) displayed at the touched coordinate position is an area related to screen control (screen change), it is converted into information related to screen control, and C
The RT processor 4 executes the screen change processing according to it. The CRT control computer (CRT processor) 4 edits the CRT display screen based on the plant information.

FIG. 10 shows a processing function hierarchy of the prior art. When performing a control operation process, the control device controls from the touch controller through the CRT processor.
The control processing is mixed with the processing by the execution function of the CRT processor.

[0006]

Since the conventional plant monitoring and control apparatus is configured as described above, the CRT control computer performs the processing for generating the operation control information for the control apparatus belonging to the plant control and the plant monitoring. The editing processing of the CRT display screen to which it belongs is mixed, and from the viewpoint of originally reliability, the processing related to the control of high importance and the processing related to the monitoring of lower importance are not separated. However, there is a problem that is contrary to the principle of constructing a system with equipment that is required to have high reliability and that corresponds to the reliability required for functions.

If the control-related processing and the monitoring-related processing are separated, the reliability of the software that processes them can be improved. Generally, software processing related to the monitoring function (CRT display function) utilizes interrupt processing and a general-purpose operating system in order to improve the man-machine interface performance. On the other hand, regarding the control processing (continuous control, sequence control), the processing is relatively simple, so that the function can be realized by the software configuration which is the fixed cycle processing and does not have the interrupt.

In the software processing for monitoring, it is difficult to perform the verification completely because the interrupt processing is frequently used. (For example, if interrupt processing is allowed, the software execution combination (execution path) becomes infinite and it is difficult to perform complete verification such as checking all branch instructions.) As a result, it is difficult to eliminate the risk of including program bugs. Become.

On the other hand, such as control software processing,
If the software has fixed-cycle execution and no interrupts, complete verification such as full branch check is possible, and as a result, the soundness of the software can be confirmed, resulting in higher reliability. Therefore, when the monitoring software simultaneously executes the processing related to the control as in the conventional case, it causes a decrease in reliability. Therefore, it is desirable to separate the control processing and the monitoring processing in order to improve the reliability.

The present invention has been made in order to solve the above problems, and separates the processing relating to the control having a higher reliability requirement from the processing relating to the monitoring, thereby separating the processing having different reliability requirements. It is an object of the present invention to obtain a plant monitoring and control device that can be used.

【Example】

Example 1. Hereinafter, Embodiment 1 of the present invention will be described with reference to FIG. In FIG. 1, 1 is a display device (CRT), 2
Is a touch device, 3 is a touch controller, 4 is a CR
T control computer (CRT processor), 5 is a control signal transmission line for transmitting a control signal generated by the touch controller 3 to the control device 6, 6 is a control device for controlling the plant, 7 is a plant state such as a plant process amount A data way for transmitting the quantity, 8 is a database having a relationship between the coordinate position on the CRT display screen and the plant equipment operator or screen information, and 9 is screen information for transmitting the screen information being displayed from the CRT processor to the touch controller 3. It is a transmission line.

Next, the operation will be described. The CRT control computer (CRT processor) 4 has a data way 7
The plant state quantity is input from the input terminal to edit the screen to be displayed on the CRT 1, the screen is displayed on the CRT 1, and the screen number currently displayed is transmitted to the touch controller 3 via the screen information transmission path 9. A case where the operator executes the operation of the plant equipment will be described with reference to the flowchart of FIG. The desired operating device is displayed on the display screen of CRT1 (S
Touch the position 1) (S2). This touch position is transmitted to the touch controller 3 via the touch device 2. The touch controller 3 detects the touched coordinates, and combines the coordinate information and the displayed screen number transmitted through the screen information transmission path 9 to identify the operating device touched by the operator from the database 8. If it is the control information (S3), it is transmitted to the control device 6 (S4). The control information of the identified operating device is transmitted to the control device 6 via the control signal transmission path 5 and executes the control operation according to the request of the operator.

On the other hand, the touch position is screen control (screen change)
When the touch controller 3 identifies the screen information from the database 8 (S
3), CR this screen information via the screen information transmission line 9
It is transmitted to the T processor 4 (S4), and the CRT processor 4
Can execute the screen control according to the operator's request and monitor the plant by the display (S6). In this way, the control-related signal is passed only through the touch controller 3, and the processing is separated from the CRT processor that processes the monitoring information.

FIG. 3 shows a functional hierarchy diagram of the present invention. When the control operation process is performed, the control device controls without passing through the CRT processor from the touch controller, and thus the process related to the control is separated so as not to be mixed with the process in the execution function of the CRT processor. FIG. 4 is an illustration for facilitating understanding of the separated structure. As shown in FIG.
Shows the conventional configuration, and FIG. 4 (b) shows the configuration of this embodiment.

Example 2. In the first embodiment described above, the touch controller 3 and the CRT processor 4 are configured as separate devices, and the screen information transmission path 9 interfaces necessary information between them, but as shown in FIG. The touch controller 3 and the CRT processor 4 are each configured in a single computer system by a multiprocessor system.

As described above, the same effect can be obtained by the structure in which the screen number being displayed is transmitted between the two by the internal data bus 10 of the computer instead of the screen information transmission path 9, and the touch information processing can be realized in the same computer. Thus, the information transmission between the touch controller 3 and the CRT processor can be realized at high speed and easily.

Example 3. In Examples 1 and 2 above, CR
T1, touch device 2, touch controller 3 and CR
The case where there is only one supervisory control device composed of the T processor 4 has been described, but as shown in FIG.
1 ', touch devices 2 to 2', and touch controller 3
~ 3 'and CRT processors 4-4' are installed in plural sets, the operation signals coming from the plurality of touch controllers 3-3 'are arranged between the control devices 6-6' and the touch controllers 3-3 '. .Multiplexer 11 for branching
The same effect can be obtained by installing the multiplexer 11 and the plurality of touch controllers 3 to 3'and connecting the multiplexer 11 to the control devices 6 to 6'by control signal transmission paths 5 and 5 ', respectively. Further, by installing a plurality of CRTs 1 to 1 ′, it becomes a configuration in which any of the CRTs can operate the other control devices at the same time.

If there is no multiplexer 11 for such a plurality of simultaneous operations, for example, in a configuration having 5 CRTs and 5 control devices, 5 CRTs are required for direct interface.
X5 = 25 transmission lines are required, but if the multiplexer 11 is provided, only 10 transmission lines are required. Further, when contradictory operations (open and close) or the same operation are performed on the same control target, the validity of the multiplexer 11 can be checked before the control device receives the signal. .

Example 4. In the third embodiment described above, the method of connecting the plurality of touch controllers 3 to 3'and the multiplexer 11 by the control signal transmission line has been described.
As shown in FIG. 3, a plurality of touch controllers 3 to 3 ′, CRT processors 4 to 4 ′, and the multiprocessor 11 are connected by a data way 12 that transmits signals related to control and display screen information to transmit information. The same effect can be obtained, the signal transmission path can be reduced, and the operation information of other CRTs can be shared by a plurality of CRTs via the data way 12, so that a cooperative operation between the plurality of CRTs is possible. It becomes a composition.

This cooperative operation is performed by a plurality of operators sharing the roles, and since touch information can be shared among a plurality of CRTs, what kind of operation is being performed by another CRT? Can be confirmed. For example, when the same screen as the CRT being operated is displayed on another CRT, the area of the operating device being operated is changed to two CRTs.
By performing the co-reverse display, it is possible to confirm what operation is being performed on another CRT. As a result, the operation of the entire plant can be coordinated by a plurality of CRTs.

Example 5. In the above Examples 1 to 4,
The database 8 for searching the screen information and the control information from the display screen and the touch coordinate position is installed in the touch controller, respectively. However, as shown in FIG. 8, the database 8 is installed in the multiplexer 11, and the touch controller 3 Even if the coordinate position is detected and the screen information and the control information are extracted by the multiplexer 11, the same effect can be obtained, the database can be unified, and the maintenance / management for the change of the database is easy. It will be composed.
