Description

  The present invention relates to a disaster information electronic signboard that is installed at a place where the public passes or gathers and displays disaster information received from a server computer via a communication network.

  Japan is one of the world's leading disaster powers, where natural disasters such as earthquakes, tsunamis, and typhoons occur frequently due to the location of the country, weather, and topography. For this reason, various devices and systems for displaying information about natural disasters and calling attention in places with high traffic such as stations, airports, and busy streets have been introduced.

  For example, Patent Document 1 discloses an electronic signboard system in which electronic signboards installed in various regions are connected to a server computer via a communication network. In this electronic signage system, during normal times, advertisement information such as company advertisements and event notices is distributed from the server computer to each electronic signage, and the advertisement information is displayed on the display screen of each electronic signage. On the other hand, when disaster information such as earthquake warnings, weather warnings, warnings, etc. is input to the server computer, the server computer determines whether the information is related to each area where the electronic signage is installed. If the disaster information is determined to be related to the installation area, the disaster information is distributed to an electronic signboard in the installation area and the same display is performed. In Patent Document 1, when disaster information that a heavy rain warning is issued in the southern part of Hyogo Prefecture is input to the server computer, all electronic signboards installed in the southern part of Hyogo Prefecture perform the same display regarding the heavy rain warning. It is shown.

How important certain disaster information is in the electronic signboard depends on various conditions at each installation location of the electronic signboard. In addition, the types of damage that can be expected and the content of cautions that should be raised about damage are also different.
Taking the heavy rain warning described above as an example, the degree of damage due to heavy rain is likely to be greater at places where the altitude is low or near the river than at places where it is not. In addition, there are concerns about floods near rivers and landslides near mountains, but there are few such concerns in other areas. Furthermore, it is necessary to call attention to walk with caution in outdoor areas such as busy streets where there is a lot of traffic, or in station premises where feet are slippery.
However, the digital signage system according to Patent Document 1 does not consider these points at all, and determines whether or not certain disaster information is related to each installation area by using a two-choice method. It was something that was displayed uniformly. For this reason, it has been difficult to call attention to the public who saw the display.

  Such a problem is applicable not only when displaying information on natural disasters such as the heavy rain warning described above, but also when displaying information on human disasters such as terrorist disasters and nuclear disasters.

  The present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is to provide an electronic signboard for disaster information that can call the public who has seen the display more detailed and specific attention. It is to provide.

The speaker 3 outputs a voice attached to the advertisement information during normal times, and outputs an automatic voice when the display screen 2 displays disaster information of a certain level or higher.
The environmental radiation measuring instrument 4 measures the amount of environmental radiation in the vicinity of the installation location of the disaster information electronic sign 1.

  Since the disaster information electronic signboard 1 has an emergency power source including an emergency generator 5 and a battery 6 and a solar power generation system (not shown) when installed outdoors, Even if there is a power failure, it can operate for a certain amount of time (for example, about 3 to 24 hours).

Next, the operation of each part will be described by taking as an example the case where the disaster information electronic signboard 1 installed in the underground shopping center has received the earthquake early warning.
The earthquake early warning is immediately after the occurrence of an earthquake, by analyzing the observation data captured by the seismometer near the epicenter and immediately estimating the epicenter and magnitude of the earthquake (magnitude) based on this, the occurrence of an earthquake in each location The time and seismic intensity are predicted and notified. Since there is a grace period of 20 seconds or longer from the reception of the earthquake early warning to the earthquake occurrence time at the place where the disaster information electronic signboard 1 is installed, in this example, as will be described later, in units of 10 seconds with the earthquake occurrence time in between The display pattern is set with.

During normal times, i.e., when no special disaster information is input to the disaster information receiving unit 11, the telop unit 21 and the screen unit 22 of the display screen 2 are sent from the advertising information distribution organization 52 via the communication network 100 to the advertising information receiving unit 16. Displays the advertising information entered in. In addition, the speaker 3 outputs a sound accompanying the display of the advertisement information on the display screen 2.
Further, the screen unit 22 of the display screen 2 displays the environmental radiation dose acquired by the environmental radiation measuring instrument 4 at a predetermined time interval, but when the acquired environmental radiation dose is equal to or greater than a predetermined value. May be displayed only.

The operation of each unit when the disaster information receiving unit 11 of the disaster information electronic signboard 1 receives the disaster information related to the earthquake early warning will be described with reference to the flowchart of FIG.
When a disaster information distribution organization 51 such as the Japan Meteorological Agency issues an emergency earthquake bulletin, disaster information related to the bulletin is immediately input to the server computer 101 of the information distribution management organization 53 via the communication network 100. The disaster information input to the server computer 101 is subjected to processing and processing such as tagging indicating the type of disaster information, and then the disaster information receiving unit 11 of the disaster information electronic sign 1 via the communication network 100. (Step S1 in FIG. 2).

When the disaster information receiving unit 11 receives the disaster information, the disaster information determining unit 12 reads the tag added to the information by the server computer 101 and determines that the received disaster information is an emergency earthquake warning (FIG. 2 step S2).
Next, the importance level determination unit 14 reads out the disaster information from the disaster information reception unit 11 and reads out the location condition information stored in the location condition information storage unit 13 (step S3).
The importance determination unit 14 calculates or acquires the predicted seismic intensity at the installation location based on the location condition information, and determines the importance of the emergency earthquake warning based on the predicted seismic intensity to be one of levels 1 to 4. Determine (step S4). In this example, it is determined that the predicted seismic intensity 1-2 is level 1, the predicted seismic intensity 3-4 is level 2, the predicted seismic intensity 5 to 6 is level 3, and the predicted seismic intensity 7 is level 4.

  Based on the determination result, the importance level determination unit 14 determines a corresponding display pattern from among the plurality of display patterns stored in the display pattern storage unit 15 (step S5 in FIG. 2). An example of the display pattern for each level of the earthquake early warning is shown in FIG. At any level, a telop pattern is set according to the grace time until the predicted earthquake occurrence time (with 10 seconds as a rough break) and the elapsed time after the earthquake occurrence time (up to one minute later). ing. On the other hand, screen patterns are set only at levels 3 and 4. Further, in this example, an evacuation route guide map in the vicinity of the installation location of the disaster information electronic signboard 1 is stored in the instruction information storage unit 17 as instruction information of emergency earthquake warnings displayed only at levels 3 and 4. The screen patterns 3 and 4 are set to display the guide map for a predetermined time after the earthquake occurrence time. Further, when displaying the earthquake early warnings of levels 3 and 4, automatic sound is set to be output from the speaker 3.

When the display pattern is determined in this way, the instruction information corresponding to the importance of the emergency earthquake warning is read from the instruction information storage unit 17 as necessary (step S6 in FIG. 2), and the telop unit 21 and the screen unit of the display screen 2 are read out. 22 is applied to each pattern at predetermined time intervals to output display of disaster information and instruction information (step S7 in FIG. 2), and the speaker 3 outputs automatic sound.
When a predetermined time elapses, the disaster information electronic sign 1 returns to normal operation.

  As described above, the operation of each part of the disaster information electronic signboard 1 has been described by taking the emergency earthquake warning as an example. For example, when the disaster information relates to a tsunami warning, the electronic signboard 1 is installed in the inland area. If the information is included in the location condition information, the importance of the disaster information is determined as low as level 1, and the disaster information is displayed by being applied to the level 1 display pattern in the tsunami warning. Further, if it is found from the location condition information that the installation location of the electronic signboard 1 is included in the predicted arrival area of the tsunami, the importance of the disaster information is determined as high as level 4, and the disaster information Is displayed in combination with a display pattern of level 4 in the tsunami warning, together with wording for evacuating to a high ground and instruction information such as a surrounding map.

As described above, the disaster information electronic signboard 1 according to the present embodiment determines the importance of the disaster information based on the location condition information when displaying the disaster information on the display screen 2, and The display pattern is determined based on the importance.
