BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant operation mode display device, and more particularly to a plant operation mode display device for displaying a plant operation mode on a screen.

2. Description of the Related Art Generally, a complex process plant such as a nuclear power plant is composed of a plurality of systems, and some of these systems have a plurality of operation modes. For example, the residual heat removal system, which is a component of a boiling water nuclear power plant, has multiple operating modes such as low-pressure water injection mode, containment vessel spray mode, steam condensation mode, shutdown cooling mode, and fuel pool cooling mode. They each have different functions.

FIG. 2 is a simplified depiction of the residual heat removal system, in which 11 is the reactor pressure vessel, 12 is the reactor recirculation system, 13 is the pressure suppression pool, and 14 and 15 are the suctions of the pump 16, respectively. 17 is a heat exchanger, 18 is a heat exchanger bypass valve, 19 and 20 are injection valves, and 21 and 22 are check valves. These constituent members are connected by piping 23, respectively.

When using the residual heat removal system configured as described above in the low pressure injection mode, the valves 14, 18, 19 are opened, the valves 15, 20 are closed, and the water in the pressure suppression pool 13 is pumped through the pump 16. It is injected into the nuclear pressure vessel 11 using the same method. In addition, when using the cooling mode when stopped, the valves 14 and 1
8 and 19 and open valves 15 and 20 to cool the water in the reactor pressure vessel 11 with the heat exchanger 17, and then the recirculation system 12
through the reactor pressure vessel 11.

As described above, the operating mode of the residual heat removal system is changed by changing the configuration of the piping network of the system. In order to operate this system in an appropriate mode, the configuration of this piping network must be set correctly, but if the piping network of the system is complex, the configuration of the piping network that achieves the specified operation mode may be difficult. It is not always easy to monitor whether it is configured correctly.

Accordingly, computer-controlled graphics display devices have been developed and used to facilitate status monitoring of complex process plants. According to this graphics display device, data from process detectors installed at various locations in a plant can be retrieved online in real time and can be displayed on a screen with a predetermined composition. A typical example of the displayed screen is a P&ID screen that displays a piping and instrumentation diagram (hereinafter referred to as P&ID) that represents the connection of piping and instrumentation equipment in an actual plant. Since the aforementioned process data and the like are displayed at appropriate positions on this screen, the operating status of the plant can be grasped intuitively.

[0007]

However, in the prior art, the composition of the displayed screen was determined in advance. In other words, P&ID screens are created for monitoring each pre-assumed operation mode, but on a single P&ID screen, the displayed piping, equipment, and their display positions are predetermined. . The parts of these screens that change in real time include numerical values and graphs representing process amounts displayed on the screen. Further, the symbol representing the device may be transformed depending on the operating state of the device.

In any case, P&ID according to the prior art
On the screen, the composition must be programmed in advance, so
If there are many operating mode display devices, screens corresponding to all of them must be programmed separately, which is costly. Furthermore, in the event of an abnormal plant accident, etc., it is conceivable that the plant may be used in a mode different from the originally expected operation mode in order to achieve a certain function; It is not possible to pre-program a P&ID screen that properly represents the mode.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a plant that can synthesize an appropriate screen for monitoring any given operation mode without having to program the composition of the screen to be displayed in advance. An object of the present invention is to provide a driving mode display device.

[0013]

[Operation] In the plant operation mode display device configured as described above, the storage device stores graphic data of symbols commonly used to represent equipment constituting a plant, such as symbols representing pumps, valves, piping, etc. The operation mode selection device outputs device configuration data representing the operation mode. Specifically, this configuration data is data in which identification names of connected devices are listed. When the screen synthesis device receives this device configuration data, it retrieves graphic data of symbols of devices included in the device configuration from the storage device and develops them as screen data according to the device configuration data. The screen data synthesized in this way is displayed on a screen by a display device.

Therefore, in the present invention, there is no need to program the composition of the screen to be displayed in advance, and an appropriate screen for monitoring any given driving mode can be synthesized. In some cases, the user can also request the display of detailed information about the displayed plant equipment or control the equipment through the composite screen.
