Description

  The present invention relates to a building status display system.

  When confirming the safety of a deteriorated building or a building that has been subjected to disturbance (earthquakes, typhoons, etc.), it is common to leave it to a survey by an engineer with specialized knowledge.

  For example, diagnosis of the damage situation of a building after a large earthquake is performed by an emergency building diagnostician.

  Building diagnosis by an emergency building diagnostician first ranks the damage status of 20 buildings (20 buildings) or more per day, and then conducts a detailed survey of each building.

However, since the investigation of buildings after a disaster involves danger, it is necessary to perform it carefully, but there is a problem that it is necessary to conduct many investigations in a short time.
Further, since it is difficult for general users to determine the status of the building, it is difficult to determine whether the building can be used continuously.

  Therefore, Patent Document 1 discloses a deformed original position display device including a measurement unit that measures a relative displacement between two arbitrary points, and a light emitting unit that emits light according to the amount of displacement measured by the measurement unit. Yes.

If this deformed original position display device is arranged in a building in advance, it is possible to predict a displacement that has occurred in the building in advance during the survey of the building.
Moreover, since the displacement state is displayed by the color of the LED (light emitting diode) provided in the light emitting unit, even a general user who does not have specialized knowledge can judge the state of the building. It becomes.

JP 2008-309784 A

However, since the conventional deformation original position display device is capable of judging the normality with respect to the current deformation amount, the diagnosis of the soundness level of the building including the distortion that does not appear as a displacement is possible. There was still a need for detailed investigation by engineers with specialized knowledge.
In addition, since the measurement unit and the light emitting unit are integrally configured, the light emitting unit cannot be disposed at a position where the light emitting unit is easily visible by installing the measurement unit on a structure such as a pillar.

  It is an object of the present invention to provide a building status display system that makes it possible to easily visually check the soundness level of a building.

Building condition display system of the present invention to solve the above problems is a building condition display system comprising a sensor provided in the structure of the building, and a light-emitting means placed in the chamber of the building, the light emitting The means is a lighting facility, and the sensor is connected to the light emitting means closest to the sensor via a Wheatstone bridge circuit, and senses a physical quantity that correlates with a displacement generated in the structure. in accordance with the output of the Wheatstone bridge circuit changes more to the magnitude of the sensed physical quantity by the sensor by changing the display state of the light emitting means, the strain is closest structure to the light emitting means is generated Is displayed to indicate the level of soundness of the building.

  According to such a building status display system, since the level of soundness of the building can be grasped by visually recognizing the light emitting means, even a general user can judge whether to continue or stop using the building. Is possible. In addition, it is possible to conduct a survey by an emergency building diagnostician after a disaster in a short time. Further, since the light emitting means is disposed at a position where the building is easily visible, it is easy to check the level of soundness.

The light emitting means, the installed light fixtures der because the building, it is possible to inexpensively constructed compared with the case to provide a separate light emitting means.

A building status display system according to a second invention is a building status display system comprising a sensor installed in a building structure and a light emitting means installed on an outer wall of the building, wherein the light emitting means An indicator lamp or a light-emitting panel installed for each level of the building, and the sensor is connected to the light-emitting means of the level where the sensor is installed via a Wheatstone bridge circuit, and the displacement generated in the structure The light emitting means detects the display state of the light emitting means at the level where the sensor is installed according to the output of the Wheatstone bridge circuit that changes according to the magnitude of the physical quantity sensed by the sensor. It is characterized by showing the level of soundness of the building by changing.

  The light emitting means may indicate the level of soundness of the building by changing the blinking period according to the physical quantity sensed by the sensor, or the physical quantity sensed by the sensor. The level of soundness of the building may be indicated by changing the emission color according to the size of the building.

  This makes it possible to check the level of soundness of the building regardless of the surrounding brightness. In addition, the soundness level can be confirmed even when the distance from the light emitting means is long.

  According to the building status display system of the present invention, it is possible to visually determine the level of soundness of a building.

It is a mimetic diagram showing the building situation display system concerning a 1st embodiment. It is a top view for demonstrating the case where a distortion generation location is displayed by blinking of illumination. It is a schematic diagram which shows the building condition display system which concerns on 2nd Embodiment.

Preferred embodiments of the present invention will be described with reference to the drawings.
The building status display system 10 according to the first embodiment includes a sensor 11 installed in a building structure (column 2, beam 3, etc.) and light emitting means (lighting 12, And a light emitting panel 13).

  Although the structure of the building 1 is not limited, this embodiment demonstrates the case where the building condition display system 10 is installed in the structure provided with the multilayered floor.

The sensor 11 is installed in the column 2 or the beam 3 and senses a physical quantity (strain, displacement, speed, acceleration, etc.) correlated with the displacement generated in the column 2 or the beam 3.
One or more sensors 11 are installed on each floor of the building 1.

In the present embodiment, a strain gauge is used as the sensor 11.
The sensor 11 measures a physical quantity while being attached to the column 2 or the beam 3.

  The resistance value of the sensor 11 changes according to the magnitude of strain generated at the installation location. And the soundness of a structure (building 1) is displayed by making a light emission means light-emit according to the output of the Wheatstone bridge circuit (not shown) to which the sensor 11 was connected.

  In addition, the sensor 11 holds (stores) a resistance value corresponding to the strain generated at the installation location even when the supply of power is stopped. Therefore, when the power is restored, the sensor 11 indicates the magnitude of the strain. It is possible to show it again.

In addition to the strain gauge, for example, a displacement gauge, an accelerometer, or the like can be used as the sensor 11, or a strain gauge, a displacement gauge, an accelerometer, or the like can be used in combination.
Further, for example, a structure that can also measure a physical quantity, such as an optical fiber sensor, is attached to the structure to specify a damaged position, a strain amount, or the like. Moreover, you may comprise so that a damage location and distortion amount can be confirmed with a screen by comprising so that data can be transmitted to terminals, such as a computer.

  When using a displacement meter, the structure which shows visually the inclination of the whole building 1, the displacement difference for every hierarchy, etc. is taken. The displacement amount may be measured using a laser or the like.

  When using an accelerometer, frequency analysis is performed from the acceleration waveform of the building state that seems to be healthy, and this is used as the initial value, and measurements are taken periodically. The damage of the building 1 caused by deterioration or disturbance due to secular change is visually shown through the light emitting means 12 when a numerical value different from the initial value is observed as a result of frequency analysis.

  The light emitting means indicates the level of soundness of the building 1 by changing its light emitting state according to the physical quantity sensed by the sensor 11.

In this embodiment, the illumination 12 (lighting equipment) in the room 4 is used as the light emitting means, and is configured to blink when the physical quantity (strain) sensed by the sensor 11 exceeds a threshold value.
The illumination 12 is preferably composed of a light emitting diode (LED), an incandescent lamp, or the like, but a fluorescent lamp, a halogen lamp, or the like may be used.

The illumination 12 is connected to the sensor 11 via the wiring 14 as shown in FIG.
The illumination 12 and the sensor 11 are connected via an oscillation circuit, so that the light emission period (flashing period) changes according to the magnitude of the distortion sensed by the sensor 11. Thereby, the soundness level of a building can be grasped | ascertained from the blinking period of the illumination 12.

  In the present embodiment, the sensor 11 and the illumination 12 closest to the sensor 11 are connected. If it does in this way, it can visually recognize that distortion generate | occur | produced in the pillar 2 or the beam 3 of the vicinity of the blinking illumination 12. FIG.

For example, as shown in FIG. 2, four lights 12 a to 12 d are provided in the room of the building 1 including four beams 2 a to 2 d and four beams 3 a to 3 d laid horizontally between the columns 2 a to 2 d. What is necessary is just to comprise so that the illumination 12a nearest to the pillar 2a may blink when the distortion | strain arises in the pillar 2a in the case where it has arrange | positioned. Similarly, when the column 2d is distorted, the illumination 12d is configured to blink.
Further, for example, when the beam 3c is distorted, the illumination 12b and the illumination 12c arranged near the beam 3c blink, and when the beam 3a is distorted, the illumination 12a arranged near the beam 3a The illumination 12d is configured to blink.

Furthermore, when the floor is distorted, all the lights 12a to 12d are configured to blink. In addition, you may comprise so that either of illumination 12a-12d may blink according to the position where the distortion | strain of a floor produced. In this case, it is distinguished from the case where the column 2 or the beam 3 is distorted by the blinking speed.
By configuring in this way, the damaged structure and the position of the structure can be visually recognized by the blinking of the illumination 12.

  In addition, it is desirable that the illumination 12 displays a location where damage has occurred by blinking or the like even in the event of a power failure or when the electricity is turned off (when the light is turned off). In this case, a backup facility such as an uninterruptible device or a solar battery may be used.

  In the present embodiment, the oscillation circuit is an analog circuit so that the soundness level can be instantaneously displayed when the building 1 is damaged.

  Note that the light emitting means is not limited to the illumination 12, and may be, for example, the light emitting panel 13 installed on the inner wall 5. Thereby, since the installation location of a light emission means is not limited, it becomes possible to install in the position which is easy to visually recognize suitably.

  The light emitting panel 13 is configured to emit light when a physical quantity (strain in the present embodiment) correlated with the displacement of the sensor 11 is sensed, and emits light according to the magnitude of the physical quantity sensed by the sensor. Change the color to indicate the level of building health.

  The light-emitting panel 13 is configured to emit eight types of colors (including black in a non-light-emitting state and white in all three colors) by using a three-color LED, and the physical quantity sensed by the sensor 11. By performing ON / OFF control on the LED according to the size of the LED, the emission color changes. There are no limitations on the type and number of colors used to display the soundness level of the building 1, and various types of LEDs can be controlled by controlling the emission current of each color LED (red, blue, green). A color may be emitted. Moreover, you may display the soundness level of the building 1 by making the light emission panel 13 blink.

As described above, according to the building status display system 10 of the present embodiment, since the soundness level of the building is indicated by the blinking of the light emitting means or the light emitting color, even a general user who does not have special knowledge can Can understand the soundness level.
For this reason, for example, for a building in a disaster area such as an earthquake, even if a large distortion that does not appear on the appearance is generated in the structure, the user grasps it by blinking of the illumination 12 (color of the light emitting panel 13). Therefore, it is possible to evacuate safely.

  In addition, regarding the diagnosis of the building by the emergency building diagnostician after the disaster, the soundness level of the building 1 can be recognized at a glance, so that it can be used as a reference for detailed investigation.

Moreover, since the soundness level of the building 1 is displayed based on the amount of change in the physical quantity, the soundness level can be grasped more accurately.
Moreover, since it can grasp | ascertain the fall of the soundness level by deterioration of a building, it is possible to employ | adopt for judgment of the time of repair of a building, etc.

  Further, since the illumination 12 is used as the light emitting means, it can be used as room illumination at all times and is economical.

  Moreover, the illumination 12 may display the soundness level of the building 1 by changing the emission color. For example, it may be configured to change to blue when safe, yellow when attention is required, and red when dangerous.

  Similarly, the light emitting panel 13 may be configured to display the soundness level by the blinking speed, or may be configured to display a character string corresponding to the soundness level. Furthermore, an alarm sound transmission means may be provided.

  Moreover, you may be comprised so that a damage location may be pinpointed with the blinking speed of the light emission means (The illumination 12 or the light emission panel 13). For example, if the column is damaged, it will be displayed by lengthening the flashing cycle (flashing repeatedly turning on and off), and if the beam is damaged, the flashing cycle will be shortening (flashing repeatedly turning on and off) If the floor is damaged, the damaged part is indicated by displaying the flashing by alternately repeating the flashing with a long cycle and the short flashing (long lighting and short lighting) alternately.

  A building status display system 10 according to the second embodiment is installed on a sensor 11 (see FIG. 1) installed in a structure (column 2, beam 3, etc.) of a building 1 and on an outer wall 6 of the building 1. And an indicator lamp 17 (light emitting means) (see FIG. 3).

  Since matters related to the sensor 11 are the same as the contents shown in the first embodiment, detailed description thereof is omitted.

  The sensor 11 and the indicator lamp 17 are connected via a wiring (not shown). The indicator lamp 17 emits light when the sensor 11 senses a physical quantity that correlates with the displacement generated in the structure, and the light emission state changes according to the magnitude of the physical quantity.

As shown in FIG. 3, the indicator lamp 17 is installed for each level of the building 1. When the sensor 11 installed on each floor senses strain, the indicator lamp 17 corresponding to the level where the sensor 11 is installed. Emits light.
Further, the blinking speed or emission color of the indicator lamp 17 changes according to the magnitude of the strain sensed by the sensor 11.

In addition, you may comprise so that the position of the structure which the distortion | strain produced may be displayed by installing two or more indicator lamps 17 for every hierarchy.
In other words, if the indicator lamp 17 installed near the sensor 11 that senses the strain is configured to emit light, the position where the strain has occurred can be viewed from the outside of the building 1.

  In this embodiment, the case where the indicator lamp 17 installed on the outer wall is used as the light emitting unit has been described. However, the configuration of the light emitting unit is not limited to the indicator lamp, and for example, a light emitting panel installed on the outer wall. 13 may be sufficient.

  As shown in FIG. 3, the light emitting panel 13 is configured to emit light for each level of the building 1. When the sensor 11 senses the strain in the strained level, the light-emitting panel 13 installed on the outer wall corresponding to the level emits light. The light emission panel 13 can recognize the magnitude | size of the distortion | strain in the floor where the distortion | strain produced, and its hierarchy from the exterior of the building 1 because a color changes according to the magnitude | size of a distortion | strain.

  As described above, according to the building status display system 10 according to the second embodiment, the soundness level of the building can be confirmed from the outside of the building 1. Therefore, for example, it is possible to quickly rank the damage situation by an emergency building diagnostician in the affected area. In addition, since it is possible to enter the building 1 after confirming safety from the outside, the work can be performed more safely.

The light emitting means is not necessarily installed on the outer wall 6, and may be installed on the window 7, for example. According to such a configuration, the soundness level of the building 1 (structure) can be confirmed from inside and outside the room. In this case, if the light emission state of the window 7 closest to the distorted structure (column 2 or beam 3 or the like) is changed, the position of the distorted structure can be confirmed. Become.
Alternatively, a liquid crystal shutter 7a may be installed in advance on a glass such as the window 7, and a color, a number, or a character may be displayed by the liquid crystal shutter to notify that distortion has occurred.

The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and the above-described constituent elements can be appropriately changed without departing from the spirit of the present invention.
For example, the use of the building 1 in which the building status display system 10 is installed is not limited.

  Further, in each of the above embodiments, the case where the building status display system 10 is installed indoors and the case where the building status display system 10 is installed outdoors have been described. May be.

In addition, when damage occurs in an arbitrary layer, it is desirable to display the occurrence of damage on other floors.
In other words, when the pillar 2 is damaged, if the damaged pillar 2 is damaged such that it cannot bear the dead weight of the building 1 or the like, the pillar 2 is damaged on all other floors. Is configured to display that has occurred. Further, when the pillar 2 is damaged but can withstand the dead weight of the building 1 or the like, the fact that the pillar has been damaged is displayed on the floor above the damaged floor.
When the beam 3 is damaged, a message to that effect is displayed on the damaged beam 3 and its upper floor. Further, when the floor is damaged, the fact is displayed on the floor of the damaged floor and its lower floor.

  Moreover, you may comprise so that specific information may be reported and transmitted with respect to a specific person by utilizing visible light communication technology. For example, by attaching a transmitter to the lighting 12 or the like and transmitting a signal (information) to a mobile phone, PDA (mobile terminal), electronic device, etc., special information other than information for everyone can be specified. Of individuals (for example, professional engineers) can be obtained.
