Description

[0001]
[Industrial application fields]
The present invention relates to an emergency message display system, and more particularly to a novel emergency message that displays an emergency message using a number of rescue boards each provided with an electronic display that can display at least characters integrally with, for example, an evacuation site information signboard. It relates to a display system.
[0002]
[Prior art]
Previously there was no such emergency message display system.
[0003]
On the other hand, for example, it is conceivable to display an emergency message all at once using an LED display additionally provided in the vending machine. However, when performing simultaneous distribution to all vending machines, a telephone line is required. Sequential distribution using data or simultaneous distribution using radio waves can be used.
[0004]
[Problems to be solved by the invention]
When radio waves are used, there is a problem that it is difficult to confirm whether or not an emergency message has reached each display. Further, although “confirmation” can be obtained by a method using a telephone line, there is a problem that a time difference is caused for sequential distribution.
[0005]
Such a problem causes a serious problem when such a message display system is used as an emergency message display system. For example, emergency situations such as fires, earthquakes, tsunamis, avalanches, and landslides are all related to human life. If the above confirmation cannot be taken in such an emergency situation, the local government or national system protects the safety of residents. Is not perfect. Also, in such an emergency situation, it is easily guessed that time delays can also affect human life.
[0006]
Therefore, the main object of the present invention is to provide a novel emergency message display system.
[0007]
Another object of the present invention is to provide an emergency message display system capable of confirming that an emergency message has been reliably delivered to a target display device.
[0008]
Another object of the present invention is to provide an emergency message display system capable of selecting individual distribution, group distribution, or simultaneous distribution as required.
[0009]
[Means for Solving the Problems]
The emergency message display system according to the present invention is a system for displaying an emergency message using a large number of rescue boards each provided with an electronic indicator capable of displaying at least characters integrally with an evacuation site guide signboard. A server for delivering information to the rescue board through the network, a database connected to the server, and a portable information terminal accessible to the server through the network, the server in response to the portable information terminal accessing the server A distribution destination input screen transmitting means for transmitting a distribution destination input screen to the portable information terminal, a distribution destination data receiving means for receiving distribution destination data from the portable information terminal input using the distribution destination input screen, and a portable information terminal. In response to accessing the server, an information input screen is sent to the portable information terminal. Information input screen transmitting means, information data receiving means for receiving information data from the portable information terminal input using the information input screen, and one or more indicated by the distribution destination data in accordance with the information data received by the information data receiving means It is an emergency message display system including an emergency message delivery means for delivering an emergency message to the rescue board.
[0010]
[Action]
Each rescue board is connectable to a network such as the Internet, and the server distributes information to each rescue board via the network. When it is not an emergency situation, general information such as news and weather forecasts is distributed simultaneously from this server. Therefore, such general information is displayed on the display of each rescue board. Thus, by displaying the general information without interruption, it is possible to inform the residents of the presence of the rescue board.
[0011]
When an emergency occurs, for example, a local disaster prevention person or the like accesses the server using a portable information terminal such as a cellular phone. The server confirms, for example, by password authentication whether the portable information terminal has the authority to access the server and use the emergency message display system.
[0012]
For personal digital assistants that are allowed to use the system, a distribution destination input screen is displayed on the portable information terminal so that the person in charge of disaster prevention can input the message of the emergency message distribution destination from the transmission destination input screen transmission means of the server. send. The person in charge of disaster prevention uses the distribution destination input screen, for example, “individual distribution destinations” that specify a specific one or a limited number of rescue boards, for example, all rescue boards in one town are targeted. Enter distribution destination data, such as “Group Distribution Destination” or “Simultaneous” for all rescue boards.
[0013]
On the other hand, to the portable information terminal that is allowed to use the system, to the portable information terminal so that the person in charge of disaster prevention can input information indicating what kind of emergency situation from the information input screen transmission means of the server Send information input screen. The person in charge of disaster prevention uses the information input screen to input information indicating, for example, when and where.
[0014]
Therefore, the emergency message delivery means of the server delivers the emergency message to one or more rescue boards indicated by the delivery destination data according to the information data received by the information data receiving means.
[0015]
When the server includes a completion transmission unit, a distribution completion signal indicating that the emergency message distribution unit has distributed the emergency message to all necessary distribution destinations is transmitted to the portable information terminal.
[0016]
【The invention's effect】
According to the present invention, a novel emergency message display system using a rescue board can be obtained. Further, when a delivery completion signal is sent from the server to the portable information terminal, it can be seen that the urgent message is reliably delivered to the target rescue board. Further, individual distribution, group distribution, or simultaneous distribution can be performed as necessary, and a necessary emergency message can be surely delivered and displayed at a necessary place.
[0017]
Other objects, features and advantages of the present invention will become more apparent from the detailed description of the following examples given in conjunction with the accompanying drawings.
[0018]
【Example】
Referring to FIG. 1, an emergency message display system (hereinafter simply referred to as “system”) 10 of this embodiment is realized in the form of a website using Internet 12. This website is managed and operated by the server 14.
[0019]
The system 10 further includes a rescue board 16 that can be connected to the Internet 12. The rescue board 16 refers to a combination of an evacuation place guide sign 18 that indicates the position of an evacuation place such as a wide area refuge and a display 20 that is integrally supported by the sign 18 with a pole or the like. This sign 18 is used to guide where the evacuation sites set in schools, parks, etc. are located, like the currently used evacuation signboards. And the guidance are described in a visible manner. And although only one such rescue board 16 is shown in FIG. 1, many rescue boards 16 are scattered in the city area. Each of the multiple rescue boards 16 includes a computer as shown in FIG. 2, thereby having a function of connecting to the Internet 12. The display 20 is an electronic display that can display at least characters. In this embodiment, an LED display in which a large number of light emitting diodes are arranged in a matrix is used. However, the color of the light emitting diode is preferably three primary colors of red, green and blue in view of the variety of display colors, but it is needless to say that red and green or only one color may be used. However, when the LED display 20 is used, not only characters but also animations can be displayed.
[0020]
The server 14 of the system 10 steadily displays general information (stationary program information) such as news, weather forecasts, and sports news supplied from the program site 22 via the Internet 12 or a telephone line by LED display on the rescue board 16. Display on the vessel 20. However, for example, in response to an emergency message display instruction from a portable information terminal typified by the mobile phone 24, an emergency message is displayed on the LED display 20 as described later. However, the server 14 determines which rescue board is given regular general information and which rescue board is displayed with an emergency message based on data registered in the database 26 in advance.
[0021]
The rescue board 16 shown in FIG. 2 includes a CPU 30, a ROM 32, and a RAM 34 connected to each other by a CPU bus 28, and an Internet interface 36 is further connected to the CPU bus 28. Therefore, the CPU 30 can access the Internet 12 and thus the server 14 (both in FIG. 1) through the interface 36. A display interface 38 is further connected to the CPU bus 28. The display interface 38 includes a character generator (not shown), for example, and supplies dot data (display data) to the LED display 20 in accordance with character data sent from the CPU 30. Therefore, the LED display 20 can display information (general information or emergency message) acquired by the CPU 30 via the Internet interface 36.
[0022]
Specifically, the server 14 steadily provides regular program information to the CPU 30 of the rescue board 16 via the Internet 12 (FIG. 1) as shown in step S1 of FIG. In response, the LED display 20 of the rescue board 16 displays the general information (stationary program information) as described above.
[0023]
Then, for example, when the occurrence of an emergency situation is notified from the cellular phone 24 (FIG. 1) to the server 14, the emergency situation is determined in step S2, and the server 14 uses the LED display 20 of the rescue board 16 in step S3. Display an emergency message.
[0024]
Explaining in detail, when an emergency occurs, for example, emergency responders such as disaster prevention officers, police officers, fire department staff, etc. of local governments use dedicated mobile phones provided by the local government, etc., or personal mobile phones. In step S11 of FIG. 4, the server 14 (FIG. 1) of the system 10 is accessed.
[0025]
In response to the access, the server 14 sends an authentication data input screen as shown in FIG. 5 to the cellular phone 24 and requests authentication data (input) in step S21 of FIG. Accordingly, in step S12, the emergency responder inputs authentication data such as an ID number and a password on the authentication data input screen of FIG. 5 using an operation key (not shown) of the mobile phone 24, and the server 14 to send.
[0026]
This authentication data is received by the server 14 in step S22. Then, the server 14 compares the received authentication data with data registered in advance in the database 26 (FIG. 1), and determines whether or not the authentication data is OK. If “NO” is determined in the step S23, that is, if unregistered authentication data is received, the server 14 executes another process.
[0027]
On the other hand, if it is determined in step S23 that the authentication is OK, the server 14 transmits a delivery destination menu screen as shown in FIG. 6 to the mobile phone 24 through the Internet 12 in the subsequent step S24. In response, the emergency responder uses the mobile phone 24 to input whether the distribution destination is (1) individual, (2) group, or (3) simultaneous on the distribution destination menu screen. When the individual delivery of (1) is selected, information indicating the location where the rescue board of the individual delivery destination is installed, in the example shown, “XX ward ×× cho central park” is input. . This location information can also be input by a so-called pull-down menu method in which information is selected from pre-registered information as in the group information of (2). In the case of instructing the group distribution in (2), for example, information on a place where some rescue boards forming the group are arranged is input as group information. In the illustrated example, “XX ward XX town”. (3) When simultaneous delivery is selected, it is not necessary to input delivery destination information.
[0028]
FIG. 7 shows an example of grouping. In the example of FIG. 7, each group independently forms an arbitrary number of rescue boards, but one or a plurality of rescue boards may be registered in a plurality of groups. A group may be formed with only one rescue board.
[0029]
Note that (1) individual distribution is used when, for example, a fire occurs and an evacuation request is made in the vicinity of the location. However, it is possible not only to specify one individual rescue board, but also to specify a plurality of individual distribution destinations without using group distribution or simultaneous distribution. (2) Group distribution is used when calling for evacuation to residents in a relatively large area at the same time, such as when a large-scale fire or landslide disaster due to rainfall is predicted, or when a tsunami due to an earthquake is predicted . However, not only one group but also a plurality of group distribution destinations can be designated. Note that (3) simultaneous distribution is used in addition to the regular program and general information as in step S1 in FIG. 3, for example, when a disaster is expected to cover the entire area such as an earthquake or volcanic eruption. However, the specific examples described above are merely examples, and if necessary, (1) individual distribution, (2) group distribution, or (3) simultaneous distribution is selected as necessary.
[0030]
When the delivery destination data is input from the mobile phone 24 in step S13 in this way, the server 14 searches the database 26 for a rescue board to which an emergency message is to be delivered in accordance with the delivery destination data described above in the next step S25, Determine the rescue board as the delivery destination. That is, in the database 26, for example, as shown in FIG. 8, the installation location of the rescue board, the IP address individually assigned to the rescue board, the group name formed by the rescue board, and the general information Is registered in advance, and information such as the delivery time is registered. In step S25, the server 14 refers to the registration information in the database 26 and identifies a delivery destination rescue board.
[0031]
In the subsequent step S26, the server 14 transmits an information input menu screen as shown in FIG. The information input menu screen is used for inputting information such as where, when and what has occurred in a fixed sentence as much as possible. That is, by using such an input screen, there is an advantage that the input format of information from all emergency responders can be unified. Then, when the mobile phone 24 transmits input data using this input screen, the server 14 receives the input data in step S27, and in step S28, the emergency message is determined as one of the delivery destinations determined in step S25. Send to one or more rescue boards. That is, when the delivery destination is determined in step S25, the server 14 specifies an address assigned to the rescue board of the delivery destination, and transmits an emergency message to that address in step S28. Therefore, for example, an emergency message as shown in FIG. 10 is displayed on the LED display 20 (FIG. 1) of the rescue board designated.
[0032]
In addition to the urgent message to be displayed, the server 14 repeatedly displays a numerical value indicating the urgency level (for example, “1-5”, which indicates a higher urgency level in ascending order of the numerical value). The number of times (for example, “1-99” designates the number of times. However, “0” indicates continuous display.), Display time interval (however, only for repeated display), and the like may be included. In this case, the CPU 30 of the rescue board 16 repeatedly displays the urgent message for the specified number of repetitions at the specified time interval. However, in the case of continuous display, the display is continued until a cancel command is input from the server 14.
[0033]
Further, in the rescue board 16, when the information to which the emergency rescue board is given is transmitted from the server 14, as shown in step S3 of FIG. To do. However, when an emergency message having an emergency level equal to or higher than that of the currently displayed emergency message is delivered, the CPU 30 of the rescue board 16 overwrites the emergency message and displays a new emergency message. .
[0034]
Further, when displaying an emergency message, the CPU 30 of the rescue board 16 may display a special decorative frame on the LED display 20. When the decorative frame is displayed, it is possible to easily visually recognize different emergency situations depending on the display color and display method of the decorative frame.
[0035]
When the emergency message is distributed from the server 14 to the rescue board 16, a mail confirming receipt of the emergency message is returned to the server 14 from each rescue board 16 that has received the emergency message, that is, its CPU 30 (FIG. 2). Therefore, the server 14 can determine whether or not the delivery of the emergency message to the necessary delivery destination has been completed (step S29).
[0036]
When the received mail is sent from all the delivery destinations, “YES” is determined in step S29. Then, in the next step S30, the server 14 notifies the mobile phone 24, that is, the emergency responder that the delivery of the emergency message has been completed, and ends the process. Therefore, the mobile phone 24 can determine the completion of distribution in step S15. When the completion of distribution is confirmed in step S15, the process ends.
[0037]
Note that, as shown in FIG. 9, by unifying the input format of information that conveys an emergency situation, the server 14 can easily determine what kind of emergency message should be used. That is, the server 14 can create an urgent message by changing only the variable part of the urgent message of the standard text registered in the database 26 in advance.
[0038]
In the above-described embodiment, the mobile phone 24 functions as an information input device. However, as such an information input device, other mobile information terminals such as PDAs can be used in addition to mobile phones (including PHS).
[0039]
Furthermore, instead of or in addition to the information embodiment, the following processes and operations are possible.
[0040]
The occurrence of an emergency is notified by displaying a decorative frame on the LED display 20 under control from the server 14, but the display 20 can be controlled by control from an emergency button (not shown) provided separately. . Then, the occurrence of an emergency can be notified to the server 14 using the button.
[0041]
By installing a camera (digital video camera or digital still camera) on the rescue board 16, the status of the installation location of the rescue board 16 can be transmitted to the server 14.
[0042]
If solar power generation or wind power generation is used, the battery can be charged so that an emergency message can be displayed even when the power to the rescue board 16 is cut off.
[0043]
By connecting an IP telephone to the rescue board 16, it is possible to use a telephone call and broadcast using a speaker.
