Description

  The present invention obtains the surface displacement and submergence range due to surface / deep layer collapse, which is a precursor of landslide disasters, from the positioning of quasi-zenith satellites, automatically activates broadcast radio waves etc. issued by municipalities such as J-ALERT, etc. The present invention relates to an evacuation guidance system that guides an outsider to a safe evacuation place quickly and accurately along an indoor evacuation or evacuation guideway.

  If a major earthquake or armed attack such as a tsunami has already occurred, the communication satellite will be used to instantly transmit it to local governments, and the broadcast municipal disaster prevention administrative radio and cable broadcasting telephone connected to the network will be automatically activated. There is a J-ALER system that transmits emergency information to residents through sirens and broadcasts.

  However, in landslide disasters, it is uniformly transmitted to local residents by means of sirens, broadcasts, and emergency mail based on the amount of rain, etc. There are limits to the way to guide to public halls and schools.

  Also, there is no evacuation guideway marked by a section, and no safety route is secured, such as guidance to a dangerous direction or falling into a manpole with a covered side gutter or lid covered during evacuation.

  In the dark, it is possible to evacuate through the uneven surface of the block for guiding the visually impaired, but there is a hindrance to movement with wheelchairs and stretchers. There is a current situation that only visually handicapped people who are limited to non-light-sensitive people use it.

  From this, magnetic bodies, light-reflexive reflectors, RF-ID tags, and other guides for substitutes for visually impaired people are read and read along with various sensors installed in the wand, At the bifurcation point, there is a publicly known means that uses radio waves, infrared rays, and ultrasonic waves emitted from the cane to determine the direction and guide it to the target direction, but the way of carrying the cane and the detection range is narrow and the distance is short, both are directional There are defects such as inability to detect the taxiway itself due to lack of, misidentification of other positions and materials, differences in reading direction and order, and inability to accurately guide in different directions, and flooding There is a drawback that the direction of the specific evacuation site is unknown at taxiways and intersections / branches.

  The problem to be solved is that landslides, landslides, debris flows, and so on. It is completely unclear until it is erased and confirmed visually and visually, and the inclination of the pile and the acceleration applied to the wire and net stretched on the pile have been detected, but there is a drawback that the notification is delayed.

  In addition, there is a problem that the time and route required for evacuation are not secured, and the manpole is covered with a hidden ditch and a cover is dropped during evacuation.

    On the other hand, the evacuation through the block for guiding visually handicapped who is effective in the dark is also avoided by sighted people because the surface irregularities interfere with normal walking.

  In order to solve this problem, the method of guiding the sign guideway with sensors, etc., and the guidance at the intersection / branch point, the sensor attached to the cane lacks the way to carry the cane, the directivity, and the detection distance. It is pointed out that the road is misdetected and guided in the wrong direction.

  Although the positioning error of the quasi-zenith satellite is only a few centimeters, it is difficult to detect surface displacement and flooding without specifying the dangerous location or range as the observation point.

  Furthermore, at intersections and branching points in navigation using quasi-zenith satellites, guidance to the destination using the left and right turn word expressions is possible, but only for inexact taxiways, dedicated mobile phones for pedestrians A communication terminal is required, and there is a drawback that time-consuming evacuation is delayed for confirmation and detection rather than movement along a road marking or a block for guiding a visually impaired person.

  The present invention uses the positioning accuracy of the quasi-zenith satellite to detect the surface displacement, which is a precursor to sediment disasters, as well as the main device equipped with a GPS communication terminal with a function to identify the flooding area directly connected to inundation. Fixed on the slope, steep slopes, cliffs where landslides are likely to occur, valley lines from the mountains where debris flows out, and evacuation taxiways where flooding directly connected to flooding is likely to occur.・ Install on the surface layer of the branch point.

  In the GPS communication terminal, the main device ID and the antenna position / coordinate for each installation location to be transmitted to the municipality are set in advance, and the displacement allowable value of the same coordinate or the flood height to be notified is set. Disseminate information when the flood level is exceeded.

  Furthermore, the GPS communication terminal has voice guidance and LED at the intersection / branch point of the taxiway that is transmitted from the municipality in advance to the broadcast municipal disaster prevention administrative radio and adapted to the ID of the main device at each installation location. The direction of the arrow of the sign, and also the signal of the evacuation level displayed on the evacuation level indicator light is converted into the respective sign output and automatically activated to quickly evacuate local residents and outing persons along the evacuation and evacuation guideways. Guide to the evacuation site accurately.

  In order to find and secure the evacuation time and evacuation route, it is ideal to set the antenna position / coordinate displacement tolerance of the GPS communication terminal as small as possible and set it to several centimeters. Considering the vibration and mischief of solar panels attached due to strong winds, and also maintenance, etc., the structure will transmit information when a certain level is exceeded.

  The allowable displacement value of the antenna position / coordinate and the distance to the disaster prediction area as the information transmission destination are obtained by the following formula 1, and the required time from the displacement detection to the disaster prediction area is obtained by the formula 2. The speed of debris flow varies depending on the position and slope, but it is said to be around 20 to 40 km per hour, and pedestrians move at a speed of 4 to 10 km per hour. It can be avoided. Here, the time lag of the device is 5 seconds, the debris flow is 40 km / h, and the pedestrian is 4 km / h.

  The taxiway is provided on a sidewalk where the water depth becomes shallow so that the road marking can be confirmed with a flashlight from above, even if it is flooded at night. The width is 0.45 m and the width is 0.15 m on both sides. In principle, it is structured so that it does not straddle side grooves and manholes over the entire length, and LED arrow display sections for four directions are provided on the upper surface of the intersection / branch section of the taxiway, and the arrow in the guidance direction blinks and evacuates Depending on the level, flicker blinks 1 to 3 times.

  In order to enable evacuation with wheelchairs, stretchers, etc., the surface of the taxiway has no irregularities and the above-mentioned high-intensity road marking is applied.

  A voice with a CMOS laser sensor that measures high-intensity road markings at a distance of about 600 ± 400 mm for the visually-impaired person to evacuate, with an optical axis parallel to the laser beam and an LED arrow display unit for each of the four directions. An infrared transmitter for activating an infrared receiver for activating guidance is combined to form a portable terminal for the visually impaired.

  When walking in the manner of illuminating the taxiway with a flashlight, the mobile terminal vibrates while detecting the high-intensity road markings on both sides, and the direction of travel when the infrared transmitter and infrared receiver match in the relative direction at the intersection / branch point It is possible to receive direction guidance according to the direction based on the standard, and even visually impaired persons, including those with low vision, can attach to the cane so that they can move along the guideway without relying on the cane. At this time, in order to avoid malfunction due to an infrared signal from directly above, a guard is provided directly above so that infrared light does not directly hit the light receiving element.

  Furthermore, automatic driving of electric wheelchairs along high-intensity road markings and the addition of infrared transmitter / receiver channels will enable guidance according to obstacles and foreign languages.

  The present invention has an advantage that by using a GPS communication terminal compatible with a quasi-zenith satellite, it is possible to evacuate quickly and accurately at a surface displacement or a shallow inundation stage, which is a sign of a sediment disaster.

  In addition, there is an advantage that at the intersection / branch point of the taxiway, you can evacuate to the safety direction and the facility quickly and accurately according to the voice, the evacuation level indicator lamp, and the lighting arrow.

  Predictive detection is possible at the ground displacement width and about several centimeters level, and it has the advantage of being able to detect not only the time and distance required for evacuation but also vibrations caused by wind of the solar panel, as well as any level considering mischief and maintenance. is there.

  Stations, subway / passenger terminals, public facilities in foreign languages not only with Japanese-only tourist guides with handheld terminals for the visually impaired, regardless of the presence or absence of walking sticks, but also with multi-channel infrared transceivers There is an advantage that you can receive guidance and route guidance.

  In addition, when a high-intensity road marking is detected on a pedestrian crossing, pedestrians and electric wheelchairs send out high-level positioning information using radio signals, so that vehicles running along the lane are also alerted. Yes.
