Description

  The present invention relates to a central control room that operates and monitors equipment in a power plant, and in particular, in a central control room that is not provided with an outdoor window such as a nuclear power plant, the concentration of monitoring work by operators is concentrated. It relates to a central control room in a power plant that can be enhanced.

  A central control room is installed in a power plant, for example, a nuclear power plant. For example, as shown in the plan view of FIG. 5, the central control room 1 is a facility that controls the nuclear power plant to operate safely. The central control room 1 in this nuclear power plant is a control room that controls and controls everything from nuclear fission to power generation by operating and monitoring nuclear reactors, turbines, and generators. Furthermore, radiation monitoring is centrally managed here. The nuclear power plant is usually operated automatically, but the central control room 1 is a place where operators work in three shifts 24 hours a day. For example, an operator is always provided in the central control room to control and monitor the output in the nuclear power plant. The operator controls and monitors various devices at the operator desk 6 based on the measurement and calculation data of the central control panel.

  The work in the central control room is often a monitoring operation using a large number of liquid crystal screens, for example, a flat display (FD). VDT (Visual Display Terminals) work using a large number of FDs, that is, gaze work on a display screen such as a monitor of a personal computer, is the center. Therefore, the lighting in the central control room has been ergonomically designed to form a space with a sense of tension with an emphasis on appropriate monitoring and operation. For example, the interior lighting employs an optical ceiling method using a white louver for the purpose of ensuring illuminance necessary for driving operation monitoring.

  On the other hand, the central control room of a nuclear power plant has an outdoor window to prevent exposure of operators due to radiation released outdoors during a loss of coolant accident that may occur in the reactor pressure vessel. Not provided. Therefore, the central control room is a closed space for the operator.

There have been proposed technologies for illuminating the inside of a facility where light is blocked from the outside, such as a control room of a power plant. For example, in “illumination device and illumination method and room thereof” of Patent Document 1, an illumination device that includes an illumination lamp that performs indoor illumination and in which the illuminance of the illumination lamp corresponds to the amount of sunlight is used. The first illumination lamp corresponding to the amount or direction of sunlight from sunrise to sunset and the second light of a different color system corresponding to the amount or direction of sunlight from sunset to sunrise An illuminating lamp is provided to measure the change in the amount of sunlight, and the illuminance of the first illuminant is controlled by the change in the amount or direction of sunlight from sunrise to sunset. And the illuminance of the second illumination lamp is controlled by the change in the amount or direction of sunlight from sunset to sunrise, so that at least one of color temperature, irradiation direction and illuminance is succeeded. Changing lighting devices have been proposed
JP 2001-257083 A

In addition, a technique related to a control room of a nuclear power plant has been proposed so that an operator can work for a long time while maintaining tension. For example, in “Control Room and Configuration Method of Nuclear Power Plant” of Patent Document 2, in the control room of the nuclear power plant, the ceiling extends across the ceiling and is welded to the metal plate. A control room has been proposed that consists of cooling fins extending downwardly over a first distance toward the floor of the room and attached to the metal plate and a concrete slab provided on the top of the metal plate.

  In general, in order to restore a three-dimensional world from two-dimensional information reflected on the retina of a person (operator) during monitoring work, the human visual system uses various information. A three-dimensional effect and perspective are born when the object moves on the retina or when a person moves. However, as shown in FIG. 5, when the operator is quietly monitoring the operator desk 6 based on the measurement and calculation data of the central control panel, it is difficult to create a stereoscopic effect and a sense of perspective. When the operator performed monitoring work on a large display panel, there was a problem that an error in monitoring performance was likely to be caused, and concentration power was likely to be reduced.

  Here, “Lighting device and lighting method and room thereof” in Patent Document 1 can control indoor lighting as daytime and night atmosphere lighting without using a control device such as a computer or a timer, and monitor and control without windows. People who work in places where sunlight is not incident, such as a room, can feel day and night in a more natural state throughout the day, and can only work and work while maintaining biological rhythm. there were.

  Patent Document 2 “Nuclear Power Plant Control Room and its Configuration Method” can maintain a comfortable room temperature, but does not maintain the operator's tension.

  The present invention has been developed to solve such problems. That is, the object of the present invention is to improve the monitoring ability and concentration when the operator performs monitoring work on a large display panel by devising the shape of the walls and ceiling in the central control room and the pattern and color of the surface. It is to provide a central control room in a power plant that can relieve the stress on the operator while increasing the power.

  According to the present invention, an operation monitoring auxiliary panel (4) composed of a large display panel arranged in a substantially curved manner from the back side of the control room toward the indoor side, and a central operation monitoring panel having a desk disposed on the front side thereof ( 5), an operator desk (6) arranged so as to face the central operation monitoring panel (5), and a duty-long desk (9) and a duty-deputy desk (9) are adjacent to the rear of the operator desk (6) In the central control room (1) of the power plant arranged in this manner, the inner wall (12) is arranged so as to continuously expand from both ends of the operation monitoring auxiliary panel (4), and both inner walls (12) Provides a central control room in a power plant, characterized in that the interval between the inner walls (12) is reduced from the floor (14) to the ceiling (13).

It is preferable to form a linear pattern (16, 17) on the inner surface of the inner wall (12) and the floor (14) surrounded by the inner wall (12) so as to face the operation monitoring auxiliary panel (4).
It is preferable that the ceiling (13) and the inner wall (12) constituting the central control room (1) are colored off-white.
It is preferable to lay a cold dark tile carpet on the floor (14) surrounded by the inner wall (12).
In the ceiling (13), the central operation monitoring panel (5), the operator desk (6) and the upper desk area (9) of the operator and the upper desk area of the duty auxiliary desk (9) are double-ceilinged (15). ).

In the present invention configured as described above, the monitoring work area centered on the operation monitoring auxiliary panel (4) and the central operation monitoring panel (5) is symmetrical in consideration of the driver's habitability, and the front gradually narrows. Both inner walls (12) can increase the independence of the monitoring work space from the entire space of the central control room (1), and the operator's visual field can be concentrated forward. Further, since the inner wall (12) is inclined inward and inward, the concentration of the operator can be further enhanced.
The present invention forms a living space in consideration of a sense of unity and balance of the entire space of the central control room (1). It also gives visitors the impression of a central control room (1) such as an advanced nuclear power plant, and also gives them a sense of security and reliability from a technical perspective.

Further, by forming a linear pattern (16, 17) toward the operation monitoring auxiliary panel (4) on the inner surface of the inner wall (12) and the floor (14) surrounded by the inner wall (12), this linear Spatial processing maintains the operator's tension and increases the concentration.
Further, the inner surface of the ceiling (13) and the inner wall (12) constituting the central control room (1) is colored off-white, and the floor (14) surrounded by the inner wall (12) has a cold-colored dark color. By laying the tile carpet, it is possible to bring calmness in the central control room (1) and give the driver a sense of security.

By doing so, the space in the central control room (1) can be expanded, and a feeling of comfort can be produced.

  The central control room in the power plant of the present invention is arranged with an operation monitoring auxiliary panel composed of a large display panel, a central operation monitoring panel, etc., and the inner walls are continuously expanded from both ends of the operation monitoring auxiliary panel. It is arranged, and both inner walls are inclined from the ceiling to the floor toward the central control room, and it is devised to create a space that fosters a sense of comfort as well as a sense of tension.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a plan view showing an arrangement state of devices in the central control room in the power plant according to the first embodiment.
The central control room 1 is installed adjacent to a building such as a nuclear reactor. On one side of the central control room 1 (the lower position in the drawing in FIG. 1), there is a visitor gallery room 2 for visitors who have visited the nuclear power plant. A visitor can observe the inside of the central control room 1 from the window 3 of the visitor gallery room 2.

  In the central control room 1, there is arranged an operation monitoring auxiliary board 4 which is substantially curved from the back side toward the room side and is composed of a large display board (in the upper position in FIG. 1). The operation monitoring auxiliary panel 4 is a large display panel displaying a plurality of instruments together with a circuit diagram of the nuclear power plant.

  A central operation monitoring panel 5 in which desks are arranged in a curved shape is arranged in front of the operation monitoring auxiliary panel 4. The central operation monitoring panel 5 is a display in which display screens of a number of devices in a nuclear power plant, that is, control devices for displaying the operation and monitoring status of a nuclear reactor, a turbine, and a generator are arranged.

  An operator desk 6 is arranged in front of the central operation monitoring panel 5 so as to face the central operation monitoring panel 5, and a control device is also provided in the operator desk 6. The operator desk 6 is provided with an auxiliary equipment control device 7 and an ITV console 8 so as to be adjacent to the right and left sides thereof. On the rear side of the operator desk 6, a duty-long desk 9 and a duty-deputy long desk 9 on which an operator who monitors the operation on the day is seated are arranged adjacent to each other. A meeting corner 10 can be provided in the central control room 1 (in FIG. 1, the lower left position in the drawing).

The central control room 1 is provided with an inner wall 12 separately from the concrete wall 11 that partitions the building of the power plant facility. The inner wall 12 is a wall surface formed in a substantially trapezoidal shape, which is continuous from both ends of the operation monitoring auxiliary panel 4 of the large display panel and becomes wider on the rear side of the operating operator. In other words, the inner walls 12 are substantially symmetrical and have a shape in which the front gradually narrows in consideration of the driver's habitability in the monitoring work area centered on the operation monitoring auxiliary panel 4 and the central operation monitoring panel 5. ing. In FIG. 1, a missing portion in the middle of the inner wall 12 indicates an entrance / exit 12 a to the inside.
In addition, about the installation shape of both the inner walls 12, if it is a substantially left-right symmetric shape and becomes the installation shape which the front gradually narrows, it will not be limited to the shape of the example of illustration.

  A visual information collection range that can be used effectively when performing a certain work is referred to as an effective visual field. In general, it is said that the visual field of a person (operator) is 180 degrees left and right and 150 degrees up and down. The width of the effective field of view and the depth of information processing are inversely related, and the effective field of view becomes narrower as the proportion of attention in the work increases. Therefore, the inner wall 12 allows the monitoring work area centered on the operation monitoring auxiliary panel 4 and the central operation monitoring panel 5 to be narrowed from the entire space of the central control room 1 by the substantially symmetrical inner wall 12 that gradually narrows the front. The independence of the monitoring work space can be improved and the operator's view can be concentrated.

FIG. 2 is a cross-sectional view of the central control room in the power plant according to the first embodiment.
As shown in the drawing, both the inner walls 12 are configured such that the interval between the inner walls 12 from the floor 14 toward the ceiling 13 is reduced. The inclined inner wall 12 prevents the effective field of view from being narrowed. Thereby, the concentration of the operator can be increased.
As for the inclination angle of the inner wall 12, an inclination angle of about 5 degrees is appropriate as shown in the example because it gives the operator a feeling of pressure when it is extremely inclined. However, of course, this inclination angle is not limited to 5 degrees.

  Further, on the ceiling 13, the central operation monitoring panel 5 on which the operator works, the operator desk 6, the duty desk 9, and the upper ceiling area (the area indicated by the chain line in FIG. 1) of the duty assistant desk 9 are double ceilings 15. ing. The double ceiling 15 can produce a space in the central control room 1 so as to swell. As a result, it is possible to give a feeling of comfort to the operator in a closed space without windows like the central control room 1.

FIG. 3 shows a state in which the central control room in the power plant of Example 2 faces the backmost operation monitoring auxiliary panel from the visitor's gallery room before installing the operator desk, the duty-long desk, and the duty-deputy desk. FIG. FIG. 4 is a perspective view of the central control room in the power plant of Example 2 as viewed from the window of the visitor gallery room.
In the central control room 1 of the second embodiment, linear patterns 16 and 17 are formed on the inner surface of the inner wall 12 configured as described above and the floor 14 surrounded by the inner wall 12 so as to face the operation monitoring auxiliary panel 4. By forming the straight patterns 16 and 17 in this way, the linear space processing can exert an effect of maintaining the operator's tension and increasing the concentration. This is because the effective visual field of the driver is prevented from narrowing, so that the driver's retina is stimulated to increase the forward concentration.

  Moreover, the inner surface of the ceiling 13 and the inner wall 12 constituting the central control room 1 is colored, for example, off-white. In this way, it is possible to bring calmness in the central control room 1, and it is possible to give a feeling of comfort to the operator other than during the monitoring work.

  Furthermore, a cold dark tile carpet is laid on the floor 14 surrounded by the inner wall 12. Such a colored floor 14 brings calmness in the central control room 1 and can give the driver a sense of security. This is because the cold hues have a cold, passive, and calm emotion. Incidentally, blue-green has the property of bringing about psychological effects such as repose and coolness. Blue has properties that bring about psychological effects such as calmness, loneliness, and calmness. Purple has the property of producing psychological effects such as mystery, sublime and loneliness.

  In the present invention, the shape of the inner wall 12 and the ceilings 13 and 15 in the central control room 1 and the pattern and color of the surface thereof are devised so that the operator can monitor the large display panel. Of course, as long as the improvement and concentration can be enhanced and the stress on the operator is relieved, the present invention is not limited to the embodiment of the invention described above, and various modifications can be made without departing from the scope of the invention.

  The configuration and focus of the central control room in the power plant of the present invention is diverted and applied to the control room of plants other than nuclear power plants, the control room of transportation facilities, and places where many instruments are operated and monitored based on tension. Can be used.
