Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a plant control device suitable for a control panel of a process plant such as an atomic coupler plant. The present invention relates to a plant control device that selectively displays operation switches on a display such as the above, and allows the plant to be operated using a touch screen.

(Prior Art) Monitoring and operation systems for process plants such as nuclear power plants and steel mills are large-scale and complex, and centralization is being promoted. As a result, the work space for operators has become wider, and their responsibilities have increased.

On the other hand, with advances in hardware, attempts have been made to extensively apply computer systems using CRTs as output terminals to monitoring and operating systems. For this reason, there is a growing need for consistency between computer systems and humans.

This tendency has been particularly strong in nuclear power plants since the TMI (Three Mile Island)-2 accident in 1979, and progress has been made in the development of man-machine interfaces from the operator's perspective by adding human factors to existing control panels. It is being As a result, ergonomic considerations have been made to the conventional shape, dimensions, equipment layout, etc., and the physical and mental burden on the operator has been reduced.

In addition, automation of plant operations has simplified operations and saved labor, and operating devices have also been simplified and master switches have been introduced that allow each system to be activated with a single button.

Furthermore, regarding plant monitoring work, the aim is to improve visibility by displaying such information in a consolidated form on a display such as a CRT instead of conventional meters and recorders.

In other words, by switching the CRT display screen, a large amount of information can be easily obtained, thereby omitting conventional instruments and reducing the size of the control panel.

The characteristics of this kind of CRT monitoring are that the information desired by the operator can be output on the screen, and the operator can obtain information not only from inside the central control room but also from the ground station while in front of the control panel. I can do it. In addition, the method of providing information has also been devised, such as color coding, so that abnormalities can be quickly identified by viewing the screen at a glance.

For the next generation control panels of nuclear power plants, we are aiming for a one-man operation system by further automating the above-mentioned information display and consolidating information. For this reason, control panels and the like need to be significantly downsized. Currently being considered as a means for this purpose is to omit the conventional operating tools by providing a master switch for each system.

(Problem to be solved by the invention) However, simply arranging master switches on a panel would require the operator to search for the target switch from a large number of switch groups when operating the vehicle. The probability of erroneous operation increases when operators are under a high mental burden, such as when a plant malfunctions. Further, it is undesirable that a new stress factor arises when automation of each system is promoted with the aim of reducing the burden of operation d.

Therefore, the present invention has been made in consideration of the above circumstances.
The purpose is to provide a plant IlilJgD device that can reduce the burden of operation and prevent erroneous operations.

[Structure of the invention]

(Means for Solving the Problem) The first invention of the present invention includes an event identification means for receiving a process signal from a process plant and identifying an event in the process plant, and an event identification means for receiving an event identification result from the event identification means. , switch selection means for displaying the event identification result and the combination of operation switches to be operated at the time of this event on the display of the switch display means; A touch screen that selects the operation switch to be operated by pressing a required part corresponding to the combination of the operation switches and outputs an operation switch selection signal; an operation information input means for detecting operation requests such as equipment to be operated, operation procedure, operation method, etc. and outputting an operation request signal; and according to the operation request signal, providing an equipment operation signal to the process plant to perform operation A sequential control means and an operation state in which the process plant receives a process signal from the process plant, diagnoses and monitors the process plant operating state, and stops or continues the output of the equipment operation signal from the sequential control means according to the diagnosis result. The present invention is characterized by comprising a diagnostic monitoring means and a switch display means for displaying the operation switches already being displayed on the display in different colors according to the diagnosis result from the driving state diagnostic monitoring means.

Further, in a second invention, in the first invention, the switch selection means includes means for additionally registering operation switches other than the operation switches registered therein by a switch selection operation by pressing an additional touch screen. It is characterized by the presence of

(Operation) Operation of the first invention> When the event identification means receives a process signal from the process plant, it identifies the event in the plant at that time.

This event identification result is given to the switch selection means, where a combination of this event identification result and the operation switch to be operated at the time of this event is selected and displayed on the display of the switch display means.

When a part of the touch screen corresponding to a part of the combination of operation switches displayed on this display is pressed, that part of the operation switch is selected, and the operation switch selection signal is inputted as operation information. Here, an operation request such as equipment to be operated, operation procedure, operation method, etc. is detected in the process plan 1-, and this is output as an operation request signal.

The sequential control means that receives this operation request signal applies an equipment operation signal to the process plant in accordance with this operation request signal and operates the process plant.

= 7 - When a process signal is given to the operating state diagnosis means from the process plant operated by the sequential cell control means, the operating state of the process plant is diagnosed here, and further, the sequential control means determines the process plant according to the diagnosis result. The output of the device operation signal given to the device is stopped or continued.

Further, the diagnosis result of the driving state diagnosis means is given to the switch display means, which displays the combinations of operation switches already being displayed in different colors. Therefore, the diagnosis result can be easily determined based on the color of the operation switch.

Therefore, according to the present invention, combinations of operation switches that need to be operated in response to events in the process plant are displayed on the display as appropriate, and the operation switches displayed on the display can be used simultaneously with the events displayed on the display. The process plant is operated based on this operation switch by making a selection via the touch screen with reference to can reduce the burden of

Moreover, if the operator makes a mistake in selecting the operating switch and the operating state diagnosis and monitoring means diagnoses an abnormality in the process plant, the operation of the process plant is stopped, thereby preventing erroneous operations by the operator.

<Operation of the second invention> Then, if you want to identify the state of the process plant, register it in the switch selection means based on it, and display only the necessary switches from a group of switches, depending on the event in the process plant, the operation switch It is also possible that there is a lack of. In such a case, the content registered in the switch selection means is displayed in a menu format on the additional CRT display, and the operator selects the operation switch output on the CRT display via the additional touch screen. [You can add

(Example) An embodiment of the present invention will be described below with reference to FIG.

FIG. 1 is a block diagram showing the overall configuration of an embodiment of the first and second inventions, and in the figure, a process plant 1 is an atomic couplant, a steel manufacturing plant, or the like.

In FIG. 1, a process plant 1 provides equipment conditions such as valves and pumps of each system, plant conditions such as water level and pressure to an event identification means 2 and an operating state monitoring means 3 as process signals. The event identification means 2 identifies the current state of the process plans i to 1 from these process signals.

This identification result is given to switch selection means 4 and switch display means 5, respectively. Based on the identification result, the switch selection means 4 selects the corresponding switch combination from among the combination data of the operation switch group registered in advance, and selects the operation switch to be operated in the event of the identified event.

Information on this combination of operation switches is displayed on the switch display means 5.
given to. Based on this operation switch information, the switch display means 5 displays the operation switches on the CRT display 6 together with the event identification results, for example, in a menu format.

On the other hand, the operator monitors the event identification results and operation switches displayed on the CRT display 6, selects the operation switch to be operated at the time of the event, and presses a part of the touch screen 7 corresponding to the operation switch. and select the operation switch to be operated.

This operation switch selection signal is given to the operation information input means 8, which detects which operation switch has been selected by the touch screen 7, and gives it to the sequential control means 9 as an operation request signal.

In the sequential control means 9, devices such as valves and pumps to be operated, operation procedures, and operation methods are registered in advance for each operation switch displayed on the CRT display 6, and operation 0 is displayed on the CRT display 6 by the touch screen 7. When the selected operation switch is selected, the operation information input means 8 detects which operation switch has been selected, and the sequential control means 9 determines the plant equipment to be specifically operated, and the pre-registered procedure and the selected operation switch are detected. Output equipment operation signals to the process plant according to the method. In the process plant 1, valves, pumps, etc. are actually operated according to equipment operation signals.

The operating states of these process plants 1 are determined by operating state monitoring means 3 that receives process signals.

That is, the operating state monitoring means 3 performs diagnosis and monitoring based on the constantly inputted process signals indicating the plant state, and provides the results to the switch display means 5 and the sequential control means 9.

The switch display means 5 mainly uses the diagnosis/monitoring results for changing the color of the screen being displayed on the CRT display 6, etc. For example, if the operation of process plan 1-1 is being performed normally, the CRT display 6 will display a blue color on the screen, and an abnormality 12 = abnormality or equipment failure has occurred. If this occurs, it will be displayed in a yellow or red color. This allows operation and monitoring to be performed on a single screen.

On the other hand, the sequential control means 9 uses the diagnosis and monitoring results from the driving state diagnosis and monitoring means 3 to decide whether to continue or stop the operation. If each plant equipment is operating normally, the plant equipment is operated sequentially according to the program, and as soon as an abnormality occurs in the process plant 1, output of the equipment operation request signal is immediately stopped. This makes it possible to simplify the operation of the plant.

If the status of process plant 1 is identified and the computer registers based on it and displays only the necessary switches from a certain group of switches, it is possible that there may be a shortage of operation switches depending on the event in process plant 1. It will be done. In such a case, the additional CRT display 1
0 displays the contents registered in the switch selection means 4 in a menu format, and the operator can add a publication to the operation switch that is not outputted to the CRT display 6 through the addition touch screen 11 at the operator's selection. It looks like this.

Therefore, according to this embodiment, the operator does not have to search among a large number of operation switches for the equipment to be operated at the time of a required event in the process plant 1, and since the operator does not have to operate each equipment individually, the operation operation can be greatly reduced. It is possible to reduce the burden and prevent erroneous operations.

Additionally, since there are quite a few operation switches on plant control panels that are used only a few times a year and items that are not used during normal operation, this embodiment can omit these operating tools, making the control panel more compact. can be achieved. Since a one-man operation inevitably requires a smaller control panel, the plant control device of this embodiment is considered to be extremely useful.

〔Effect of the invention〕

As explained above, the first invention of the present invention identifies an event in a process plant, displays the combination of operation switches to be operated at the time of the event on a display together with the event identification result, and displays the combination of operation switches to be operated at the time of the event on a display. Since the process plant is operated by selecting one by pressing the touch screen, there is no need, for example, to arrange a large number of operation switches on the control panel.

Therefore, according to the present invention, there is no need to search for and select the operation switch to be operated according to an event in the process plant from among a large number of operation switches, so that the burden on the operator can be reduced. Misoperation can be prevented.

In addition, in the second invention, an operation switch other than the operation switch registered in the switch selection means can be additionally registered by suppressing the additional touch screen. can be achieved.
