Description

Description: TECHNICAL FIELD The present invention relates to a plant monitoring control device, and more particularly to a plant monitoring device that dynamically displays the state of a plant.

[Conventional technology]

Japanese Patent Laid-Open No. 61-185006 is a conventional plant monitoring control device. In this conventional example, the symbol display corresponding to the plant equipment is changed according to the change in the process state. As an example of symbol display, there is a color-coded display example such as red display when operating and green display when stopped. Further, the change in the process state is judged from the input signal (data) reflecting the plant state.

Further, the plant equipment includes pipes, pumps, valves and the like.

[Problems to be Solved by the Invention] In the above-mentioned conventional example, there is a description of a symbol display example according to a process state, but the display examples such as red and green do not accurately reflect the process state, and are merely conventions. Is. Therefore, when the number of devices increases and the number of operating states increases, it becomes difficult to ensure accuracy in plant monitoring.

An object of the present invention is to switch the state of the plant to a moving image display or to display it in combination when necessary.

[Means for Solving the Problems]

The present invention relates to a memory storing moving picture display information, a means for generating a moving picture display command for reading moving picture display information of a corresponding device from the memory in a manual operation mode, and a moving picture display of the memory by the moving picture display instruction. Means for displaying a moving image of the corresponding device on the display screen based on information.

[Action]

According to the present invention, a moving image can be displayed on a display screen of a display device corresponding to a device in order to confirm the operating state of the corresponding device when starting and stopping in the manual operation mode.

〔Example〕

FIG. 1 is a diagram showing an embodiment of a plant monitoring control device of the present invention. This plant monitoring and control system consists of plant 1, control unit
2, a process input / output device 3, a computer 4, and a display device 5.

The plant 1 is composed of, for example, a power generation plant, and its facilities and equipment are controlled by the control unit 2. Further, the status signal of the plant 1 is sent to the control unit 2. The process input / output device 3 constitutes an input / output unit for the computer 4, and the control output of the computer 4 is controlled by the input / output device 3 → the control unit 2 →
The data is sent to the plant 1 and then sent to the plant 1 → the control unit 2 → the process input / output device 3 → the computer 4 for monitoring.

The computer 4 is composed of a CPU, a memory, a keyboard of input means, etc., but in FIG. That is, the computer 4 includes a plant automation control processing unit 40, a plant data input processing unit 41, a plant database unit 42, a plant information display processing unit 43, and a moving image display control processing unit 44.

The plant automation control processing unit 40 receives the data of the plant database unit 42 and generates the control output of the plant 1. Further, in the automatic operation mode, the moving image display control processing unit 44 is controlled to display the moving image. Where plant 1
The control output of is a plant start command, a valve control command, a pump speed command, and the like.

The plant data input processing unit 41 uses the process input / output device 3
The plant status signal from the device is taken in, the status signal is categorized by equipment and system, and the status signal is analyzed and processed.

The plant database unit (memory) 42 has various databases for plants. Further, the input data processed by the plant data input processing unit 41 forms a database.

The plant information display processing unit 43 is a plant database unit.
The display device 5 is caused to display the system diagram based on the data in the database of 42. Furthermore, based on the status input signal corresponding to each device, the corresponding device in the system diagram is displayed by color.

The display device 5 includes one or a plurality of display units and displays a system diagram.

The moving image display control processing unit 44 is a characteristic part of this embodiment,
By the data of the plant database unit 42 and the command of the plant automation control processing unit 40 in the automatic operation mode,
Displays a moving image of the corresponding device in the system diagram being displayed. In the manual operation mode, the driver inputs a command using the input means.

A display example in this embodiment will be described in detail.

(1) When the devices in the system are classified into two, one is a display that causes a color change as in the conventional example, and the other is a moving image display.

This classification is a method of separately displaying a device that requires moving image display and a device that does not. This classification is usually done in the database unit 42. In order to display a moving image, it is necessary to create moving image display information (screen number, device display screen position data, plant data device number, and device symbol moving image display form information for each screen). Here, the moving image display form information of the equipment symbol is based on the shape, color, and moving image form (moving image display period, shape change information, color change information, etc.) information sorted by the plant status signal (or its status code). Become. Such moving image display information exists on the database unit 42.

The moving image display information may be set in the processing unit 44.

In order to display the same color change as in the conventional example, the symbol graphics corresponding to the equipment are arranged in the database unit 42 according to the configuration of the equipment system, and the color of the symbol graphics is the operating state of the equipment of the plant (whether it is operating or stopped). It is possible to display green, red, etc. according to the distinction such as "middle".

(2) In the case where the devices in the system normally cause the color change as in the conventional example, and the moving image is displayed only when the instruction to display the moving image is given.

This is a case where a moving image target is dynamically specified and displayed. In this case, it is necessary to add moving image display information to all devices. At the time of displaying a moving image, it is the same as (1) in that the processing unit 44 is driven to display the moving image.

(3) All devices display colors in the same way as the conventional example, but when moving images are displayed near the display position, this method is an example in which moving images are displayed independently of the conventional display. Is. Therefore, a device that requires moving image display is selected, moving image display information is formed in the same manner as (1), and this is selectively displayed. It has the advantage that information can be handled easily and that video can be displayed easily.

Next, FIG. 2 shows a moving image display example by the method (3).
FIG. 2 is a display example of a system diagram, showing a display example in which a pipe 50 is connected to a device (for example, a boiler) 53, and two pipes 51 and 52 are provided in the pipe 50. In this system diagram, I want to display a movie of the piping 50, pump 51, and valve 52. Therefore, piping video symbol 50A or 50
B, the pump moving image symbol 51A, and the valve moving image symbol 52A are prepared as a part of the display moving image information and are displayed near the pipe 50, the pump 51, and the valve 52. For example, the piping moving image symbol 50A is a figure that alternately blinks at a predetermined distance, and it can be immediately determined that the liquid is flowing in the piping. The piping video symbol 50B is an example in which arrows of the flow of the fluid in the piping are displayed, and the flow direction can be visually confirmed. The pump movie symbol 51A is a figure that blinks alternately in the rotation direction so that the rotation of the pump can be seen, and the valve movie symbol 52A is a diagram that blinks alternately in the longitudinal direction of the valve. Understand. Other than this, there are various examples of moving image symbols.

Note that FIG. 2 shows an example in which a moving image is arranged near the device.
Under the display methods of (1) and (2), a moving image can be displayed on the device itself.

Next, a command for displaying a moving image will be described.

(1) Monitor the device for which a moving image is to be displayed, and display it when a status signal indicating that it is in an operating state is input.

(2) Instead of distinguishing whether it is in operation or not, distinguish between manual operation and automatic operation, and capture the status signal of the video display target device under the automatic operation command (automation control command) When it is determined that the operation is started, a moving image is displayed on the operation start device. This example is shown in FIG. By realizing the moving image display of the operation start device under such automatic driving, the driver can correctly confirm the operation device.

Further, in the manual operation mode, the driver monitors according to the monitoring target item. The monitored items may change from moment to moment or may be fixed. With respect to such items to be monitored, a moving image can be displayed in conjunction with monitoring. In this case, when the driver wants to display a moving image while monitoring the monitored items, or when there is a target device for which the moving image is displayed, the driver issues a moving image display command using input means such as a keyboard, and displays the moving image. The control processing unit is operated to display a moving image. As a result, the operating state of the target device whose operation has been stopped by manual operation can be correctly confirmed by the moving image display.

In addition, as an example of a moving image, blinking, movement, and the like are given, but this can be achieved with a change in color and a change in shape.

Note that the moving image display shows an example near the device display portion, but the entire system diagram itself can be displayed as a moving image. However, not the whole system diagram, but a part of it, for example,
The monitoring target item may be designated and only that item may be displayed as a moving image. In these cases, the "display position" in the moving image display information is not always necessary. This is because the systematic diagram itself has a data structure in a moving image display format. Therefore, when the "display position" is particularly required, this is an example of the neighborhood display.

〔The invention's effect〕

According to the present invention, during monitoring control, the operating state of the device can be displayed as a moving image, so that monitoring efficiency can be improved.
