Abstract

PROBLEM TO BE SOLVED: To attain a concentrative effect of work by partitioning a monitoring control room and an observer passage by a lattice-shaped grille, and also making brightness of the observer passage partitioned by the grille darker than the monitoring control room. SOLUTION: An observer 4 in an observer passage 2 observes an observing object in a monitoring control room 1 through a grille 3, and the grille 3 is also formed as a transparent open grille. When a grille opening dimension is denoted by (a) and an interval (e) between left and right eyes of a person is denoted by about 63mm and an interval (d) between eyes of the observer and the grille is denoted by about 120mm and an angle (c) of visibility normally recognizable by a person is denoted by 60 degrees, an optimal grille opening dimension (a) is set to almost 200mm. Illuminance of the monitoring control room 1 and the observer passage 2 partitioned by the grille 3 is also made different, and the observer passage 2 is made darker than the monitoring control room 1. Therefore, the interior of a room can be easily seen from the observer, and the observer is hardly seen from an operator, and a hindrance to the concentration on work can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
The technology relates to a partition between a monitoring control room for monitoring a large-scale control system in a traffic center or a chemical factory and a visitor passage, and a floor structure of the visitor passage.

[0002]

2. Description of the Related Art A partition is provided between a monitoring control room and a visitor passage, and a transparent member such as a glass plate or a plastic plate is employed as a partition so that a visitor can look over the monitoring control room. In addition, there is a structure in which a barrier is not provided between a monitoring control room and a visitor passage and a special barrier is not provided outside a handrail which is not allowed to enter.

[0003]

In a structure in which the space between the monitoring control room and the visitor passage is open, an accident such as a visitor enters the monitoring control room and hinders control in the monitoring control room. There is a fear of. Also, even if there are no visitors,
Visitors may be distracted by the noise of the visitors and interfere with the original work.

Further, in the case of a partition structure in which a transparent member is used as a partition, there is little possibility that an operation will be hindered for an operator, but for a visitor,
The feeling of familiarity of the surveillance and control room will be felt, and dissatisfaction will remain with respect to the feeling of intimacy, and there is no fear that the original significance of the tour is diminished.

[0005] Further, when there is a case where it is not desired to show a specific structure in the monitoring and control room to an observer, a conventional glass plate partition structure or a plain structure is not desired to be shown by itself. Things could not be shielded.

[0006]

The present invention solves the above-mentioned problems by adopting the following configuration.

[0007] The monitor control room and the visitor passage are partitioned by a grid-like open grill, and the distance between the frames of the grid-like grill is set to be approximately 200 mm as an optimum value.

[0008] In addition, by making the brightness of the visitor passage partitioned by the grill darker than that of the monitoring control room, a projection effect or a reflection effect of the grill is exerted on the floor of the visitor passage.

Furthermore, a combination of an open grill and a closed grill is used as a partition grill.

[0010] Further, a liquid crystal shutter attached to a closed grill is used as a partition to control the opening and closing of the matrix liquid crystal shutter.

1 and 2, reference numeral 1 denotes a monitoring control room, 2
Represents a visitor passage, 3 represents a grill, 4 represents a visitor, 5 represents a monitor screen, 6 represents a control console, and 7 represents an operator. Here, the grill is, in a narrow sense, a transparent one formed by forming a pattern with a frame made of metal, wood, plastic, or the like, and generally refers to a transparent one. Strictly speaking, this is called an open grill. (The grill on the left side in FIGS. 4 and 5). Although the details will be described later, a closed grill is a narrow grill and a glass partition that produces an inverted light pattern, and a pattern in which the open grill is inverted is printed on the glass. (The right grill in FIGS. 4 and 5).

1 and 2, a visitor 4 in a visitor passage 2 passes through a grill 3 to observe various objects in a monitoring control room 1 (display devices on a monitor screen 5, various types of control consoles 6). By observing the control panel and the work of the operator 7), the atmosphere of the monitoring control room 1 can be enjoyed.
The height of the floor of the visitor passage 2 is appropriately adjusted. Here, the grill 3 (a grill in a narrow sense, that is, an open grill, unless otherwise specified), unlike a conventional glass-walled partition, can directly transmit the sound and air of the monitoring control room 1 to the visitor passage 2. Therefore, the visitor 4 can feel the atmosphere of the monitoring and control room 1 with a close feeling, and can deepen the significance of the visit.

Further, by adopting the grill 3 as a partition between the monitoring control room 1 and the visitor passage 2, the observer 4 can approach the grill 3 and make the frame of the grill 3 clear of the monitoring control room 1 outside the field of view. When the observer 4 moves away from the grill 3, the supervisory control room 1 can be viewed only at the monitor control room 1 through the frame. In other words, the scene of the monitoring and control room can be freely changed according to the visitor's will (the monitoring and control room can be clearly seen when approaching the grill, and it becomes difficult to see when the distance comes away).

On the other hand, since the operator 7 in the monitoring and control room 1 is located far away from the grill 3, the visitor 4 in the visitor passage 2 through the grill 3 becomes difficult to see, and Is hardly disturbed.

FIGS. 3 (2) and 3 (3) show the relationship between one grid in the grid-like grill and the field of view of the viewer. Represents the viewing angle of the visitor, d represents the distance between the observer's eyes and the grill, and e represents the distance between the left and right eyes of the visitor. Here, the setting of the open dimension a between the frames of the grid grill shown in FIG. 3A will be described below.

The minimum size of the open dimension a should be a distance e (approximately 63 mm) between the left and right eyes of a standard person. This means dimensions that allow the observer to observe the supervisory control room without having to put the grille frame into view. In other words, when the visitor approaches the grill as much as possible, the monitoring and control room can be seen without the grill frame being in the way.

On the other hand, the maximum value of the opening dimension a is preferably the shoulder width of the child so that the child cannot enter the monitoring control room among the visitors.

When the observer observes the surveillance control room within the viewing angle without being disturbed by the grille frame, it is a distance (approximately 120 mm) normally approaching the grille, and the surveillance control is performed when the observer moves away from the grille. The optimal open dimension is such that the objects in the room are not clearly observable (while at the same time making the observer as difficult as possible for the operator). As a condition for obtaining such an optimum opening size, assuming that the distance e between the left and right eyes of a person is 63 mm, d is 120 mm, and the viewing angle c which can be recognized by a person is 60 degrees, the optimum grill opening size is approximately 200 mm. Become. Such a dimensional relationship is clear from the illustration of (3) in FIG.

FIG. 4 shows the projection effect of the visitor passage, and FIG.
Shows the reflection effect. In this case, both effects can be exhibited by making the illuminance of the two spaces partitioned by the grill, that is, the monitoring control room and the visitor passage different, and making the visitor passage darker than the monitoring control room.

Actually, since the brightness of the monitoring and control room is defined in the working environment of the operator, the space of the visitor passage is made darker than that of the monitoring and control room, so that the grill is provided on the floor of the passage. Shadows can be formed. As a result, the shadow of the grill forms a pattern on the floor of the aisle, and a visual pattern different from the physical pattern of the aisle appears to exert a staging effect. In addition, since a geometric shadow as shown in the figure is formed, there is an effect that the viewer can easily walk along the shadow.

Further, in addition to the effect of the shadow of the visitor passage as described above, by making the visitor passage darker, the observer / control room feels brighter and easier to see from the observer side, and is also easy for the operator to see. This makes it harder for a visitor in a darker visitor passage to see, thereby preventing the work from being concentrated.

The projection effect shown in FIG. 4 means that a shadow bent at 90 degrees is formed at the lower end of the grill on the floor, whereas the reflection effect shown in FIG. 5 is the lower end of the grill on the floor. Means that the shadow is not bent and the shadow is formed in a straight line. The projection effect appears when a floor material with a bright and dull floor is used, and the reflection effect appears when a floor material with a dark and glossy floor is used. FIG. 6 shows the relationship between such an effect and the floor material.

According to FIG. 6A, the projection effect is that the illuminance of the visitor passage is 30% or more darker than that of the monitoring control room, and the brightness of the floor of the visitor passage is Munsell value. V6
If the condition of having the brightness described above and the gloss of the floor being 50% or less is satisfied, it becomes remarkable. In addition, the reflection effect is to make the illuminance of the visitor passage 30% or more darker than that of the monitoring control room, the brightness of the floor of the visitor passage to be less than V6 in Munsell value, and the gloss of the floor to be lower. 50%
If the condition described above is satisfied, it will appear remarkably.

Referring to the floor material of FIG. 6B, the projection effect is a bright color, for example, a white carpet having a Munsell value V6 or more, and the reflection effect is a dark color, that is, a Munsell value V6 or less. For example, in a black P tile.

FIG. 7 shows an example in which a combination of an open grill and a closed grill is employed as a grill for partitioning between the monitoring control room and the visitor passage. Here, as shown in FIG. 3, the open grill has a structure having an opening having a frame (frame), through which air passes directly between the partitioned spaces. On the other hand, the closed grill has a transparent glass plate or the like as a substrate, and a pattern opposite to the open grill (that is, a transparent pattern for a portion corresponding to the frame of the open grill, A non-transparent pattern is printed on a portion corresponding to the opening.

As shown in FIG. 7, by alternately arranging the open grills and the closed grills, it is possible to give a sense of rhythm and a visual change to the viewer passage (see FIGS. 4 and 5). Furthermore, as can be seen from the pattern, the closed grill has a structure in which the opposite side is difficult to see, so paying attention to this, an object that the viewer does not want to intentionally show (in the monitoring control room) By arranging the closed grill in front of the door, a shielding effect can be obtained.

FIGS. 8 to 12 show various application examples of the closed grill using liquid crystal. The illustrated grill has a transparent glass plate on which a liquid crystal shutter in the form of a film is attached in a matrix.

According to FIG. 8, liquid crystal shutters arranged in a matrix of 10 rows and 6 columns are used as one partition, and as shown in FIG. Infrared distance sensors are arranged, and when a visitor approaches, the pattern of the liquid crystal shutter changes so that the opposite space can be observed. In (2) and (3) of FIG. 8, the detection of the appearance of the observer causes the central 20 liquid crystal shutters to be opened from the state where the liquid crystal shutter is closed (the left partition in (2) of FIG. 8). Is controlled.

When the liquid crystal shutter opens and closes,
By changing the gradation of the liquid crystal with time, the effect of opening and closing operation can be enhanced by gradually changing the amount of transmitted light. In addition, by controlling the liquid crystal shutter to transmit light when the power is supplied to the liquid crystal shutter, a power saving effect is exhibited without using electricity in a normal time when a viewer does not appear on the front of the liquid crystal shutter.

According to FIG. 9, an infrared distance sensor is arranged at the upper part of each partition in which a matrix of liquid crystal shutters is arranged. When a visitor approaches the partition, the sensor in the row closest to the visitor detects it, and from a measurement of the distance to the visitor, drives one specific liquid crystal shutter to change to a state in which light is transmitted. At this time, the distance from the head of the visitor whose distance was measured by the sensor was 15
Since the height under the eyes of an observer is an average person's eye height, one liquid crystal shutter arranged 15 cm below the head of the visitor is driven.

An infrared distance sensor is arranged as shown in (1) of FIG. 9 and is driven and controlled as shown in (2) of FIG. 9 so as to be adjusted to the eye level (viewpoint) of each visitor. Fine control for opening only the liquid crystal shutter at the position can be performed, and automatically adjusted to the viewpoint of a short child or a wheelchair visitor.

According to FIG. 10, when a visitor approaches the partition grill, it is detected by a sensor, and drive of a matrix-like liquid crystal shutter is controlled (FIG. 9).
(1)) and character information or patterns as shown in FIG. 9 (2) can be displayed over the entire grill.

According to FIG. 11, in a grill controlled so that the inside can be observed through a plurality of opened liquid crystal shutters, the liquid crystal shutters of the opening operation can be controlled more closely by controlling the liquid crystal shutters. Character information for visitors can also be displayed in a part of.

According to FIG. 12, a touch panel of the same size as the touch panel is provided on the front surface of the liquid crystal shutter, and the liquid crystal shutter of only the portion touched by the visitor is opened for a predetermined time to observe the inside. it can. In this case, the infrared sensor becomes unnecessary.

FIG. 13 shows a grill having a shape other than the lattice shape. The same operation and function as described above can be achieved by a grill having this shape or a grill having another pattern shape. Things.

Further, in the above description, 2
The two spaces were defined as a monitoring control room and a visitor passage, but not limited to this, but also in relation to show windows and passages, train cabs and passenger cars, laboratories and corridors, elevators and their getting on and off floors, etc. The same function and function are achieved.

[0042]

As described above, according to the present invention,
By using a grid-like open grill as a partition between the monitoring control room and the visitor passage, and setting the opening size of the grill to approximately 200 mm as the optimum value, the observation situation of the monitoring control room can be freely determined by the visitor's will. It is possible to realize the situation in the monitoring and control room with a sense of familiarity by sound and air propagation. In addition, since the operator is located at a distance from the grill, it is difficult for a visitor to see the operator, so that the work cannot be concentrated.

Further, by making the visitor passage darker than the monitoring control room, a projection effect or a reflection effect of the grill can be exhibited on the floor surface of the visitor passage to produce a space of a geometric pattern. In addition, the observer can easily see the bright monitoring and control room, and the operator becomes more difficult to see, so that the movement of the observer does not obstruct the work.

Further, by using a combination of an open grill and a closed grill as a grill, a change in grill pattern is given to the grill surface and the floor of the visitor's aisle to produce a space effect, and the closed grill is used for monitoring. It has a shielding effect that hides what you do not want to see in the control room.

Further, by using a liquid crystal grill in which a film-shaped liquid crystal shutter is attached to a transparent glass plate in a matrix form and using a distance measuring sensor or a touch panel with an observer together, one or more liquid crystal shutters can be opened and closed. By controlling the operation, it is possible to form a fine transmission window,
Character information and patterns can also be formed on the grill surface by utilizing the characteristics of the liquid crystal.
