Description

  The present invention relates to an emergency information notification system, and more particularly to an emergency information notification system that notifies emergency information to a user who uses an information terminal such as a mobile phone terminal in an emergency such as a disaster.

  As a conventional emergency information notification system, for example, as shown in Japanese Patent Application Laid-Open No. 2008-92395, a system that notifies emergency information mainly to mobile phone holders by distribution by electronic mail or Japanese Patent Application Laid-Open No. 2003-242580. As shown in the publication, a system that obtains evacuation information in a form that is visually and easily understood by the user of the distribution destination by distributing the map application using the Java (registered trademark) application to the distribution destination of the emergency information is proposed. Has been.

  In addition, as shown in Japanese Patent Laid-Open No. 2006-121535, a system for separately managing information on various blamed routes is proposed so that the blamed routes are more optimal for each user when distributing such emergency information. Yes.

  The prior art is generally configured such that all reports from a reporter are received at a facility that specializes in processing. For example, when an emergency occurs, the reporter is predicted to report to the facility at the same time so that the reporter transmits the report contents to a specific facility. In that case, if there is a limit on the number of calls accepted, if a call exceeding the allowable amount is accepted, a call that cannot be accepted occurs, and a call that exceeds the allowable amount is abandoned. It can be considered.

  Such a state is usually called an overflow, but in this overflow state, the influence of the specific increased call often affects other calls, causing adverse effects such as difficulty in accepting. Is expected to.

  Moreover, in the prior art, an emergency information delivery method has been presented, but there is a problem of when to actually deliver.

  In other words, in the distribution methods such as Patent Document 1 and Patent Document 2, urgent information is distributed to an unspecified number of people, and the influence is great, and depending on the distribution method, confusion and panic may be a factor. Can be considered.

  This invention is made in view of this subject, and provides the system which can judge emergency information newly with respect to the technique of the existing patent document mentioned above.

  In order to achieve the above object, the present invention provides an emergency information determination unit in an emergency information notification system including an evacuation route selection unit and an emergency information notification unit.

  In the present invention, for example, when the number of notification calls exceeds a certain number, information on the content of the notification can be notified to the citizens in the vicinity who have received the notification. By this, the citizen in the neighborhood where the report entered knows that the report has already been notified to the facility.

  In other words, citizens will know that a number of similar reports have already entered the facility, and citizens are expected to refrain from making similar reports that the facility already knows. it can. As a result, the facility can prevent an excessive state (overflow) of a report call by a reporter.

  In the present invention, when the number of calls from the reporter exceeds a preset value, it is determined that the degree of urgency is high, and notifications of urgent information are distributed all at once. This makes it possible to make a judgment based on more objective data than a person subjectively judges the urgency of the contents of the report, and the reporter can know more accurately about the urgency of the information. .

  The emergency information notification system of the present invention is a systemized series of flows. For example, when it is determined that the distribution processing according to the present invention needs to be performed regarding a report from a reporter (citizen), Patent Document 3 The evacuation route information managed by the method can be distributed to the corresponding citizens by the methods proposed in Patent Document 1 and Patent Document 2. Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a diagram showing a schematic configuration of an emergency information notification system. In the figure, reference numerals 0101, 0103, and 0104 denote information communication terminals, for example, citizens possessing mobile phones, 0105 denotes a facility, and 0102 denotes a base station that relays communication between the facility and the citizen's information communication terminal.

  In this system, when the facility 0105 receives a report from the citizen A (0104), the content of the report is in the vicinity of the reporter (citizen A), for example, another citizen B (0101) or citizen C (0103). If it is determined that it is necessary to notify the alarm, etc., in order to convey the information to other citizens B (0101) and Citizens C (0103), for example, through the mobile phone, This is a system for notifying a citizen B (0101), a citizen C (0103), etc. Such a system has features with respect to the following three functions.

  First, as a first function, when a report from a reporter (Citizen A) is accepted as described in the present invention, (1) the emergency information determination unit 0106 is a function that determines the urgency of the report. is there.

  The second function is a function to actually notify emergency information to other citizens B and C when it is judged that emergency information should be notified by the judgment function mentioned in the first function. (2) There is an emergency information notification unit 0108.

  Thirdly, the second function determines what information should be notified when urgent information is distributed to other citizens B and C in the vicinity of the whistleblower (citizen A). There is a (3) blame path selection unit 0107 as a function to perform.

Hereinafter, a specific system embodiment will be described for each function.
(1) About the emergency information determination unit 0106 In this function, when a report from the whistleblower (citizen A) 0104 enters as a premise for determining the degree of urgency, the contents of the report are duplicated in the facility 0105. It is to judge that the degree of urgency is high.

In other words, regarding a report with many reports, the emergency level of the report is determined from objective statistical data in the facility 0105 by judging that the level of urgency is high and likely to affect the surrounding citizens. It is possible to determine the gender and to deploy information to neighboring citizens who have been notified. Details thereof will be described in Examples 2 to 4.
(2) About the emergency information notification unit 0108 With this function, for example, such a function can be realized by using the function described in Patent Document 1 or Patent Document 2. For example, in these patent documents, regarding the base station to which the whistleblower belongs, if the whistle content is judged to be emergency information by (1) the emergency information judgment unit 0106, for example, Regarding the base station to which it belongs, notification of emergency information to other citizens B and C that also belong to the base station is performed.

As a means for notifying emergency information, Patent Document 1 is premised on delivery by e-mail, and Patent Document 2 is premised on delivery by a Java (registered trademark) application. Normally, a mobile phone terminal communicates with a neighboring base station even when the user is not making a call or sending / receiving mail, and the base station (the main server of the mobile phone carrier) It recognizes the current location information of the terminal, and this makes it possible to notify emergency information only to mobile phone users in the vicinity of the caller. This function is already disclosed in Patent Document 1 and Patent Document 2, and details thereof are omitted.
(3) About the evacuation route selection unit 0107 In considering the third function, emergency information is distributed to the citizens B and C who are actually in the vicinity of the reporter (citizen A) regarding the second function. In doing so, there is a problem of what kind of information is specifically distributed. In other words, for example, if a citizen who belongs to a base station that distributes emergency information is notified of information including the same evacuation route, all mobile phone holders belonging to the base station will choose the same route. The evacuation route is not optimized according to the owner of the mobile phone.

  With regard to such a problem, in Patent Document 3, by separately managing information on various slammed routes, it is possible to instruct the slammed routes more efficiently according to individual cellular phone users. It is possible. Note that this function is also a technique already disclosed in Patent Document 3, and details thereof are omitted.

  In the second embodiment, the emergency information notification system picked up in the first embodiment will be described, particularly regarding the emergency information determination unit 0106. FIG. 2 is a diagram illustrating a processing flow of the emergency information determination unit. Hereinafter, the present embodiment will be described according to the flow of FIG.

  In FIG. 2, first, when there is a report from the reporter (citizen A) in step 0201, the report content is registered in step 0202. The registration here may be, for example, contents corresponding to the business such as the name and address of the reporter. Subsequently, in step 0203, a determination is made as to whether there are duplicate report calls for the report call.

  The determination of such overlapping notification calls will be described in detail in the third embodiment. Specifically, regarding the notifications overlapping with respect to distance, reception time, subject, etc., the content of the notification is the same. In the next step 0204, a count up for the notification call is performed.

  Subsequently, if the reporter has not yet made a report to the neighbors of the reporter regarding the report at step 0205, and the number of report calls duplicated at step 0207 is larger than the preset set value, In step 0208, emergency information regarding the report call is notified to the neighboring citizens B and C of the reporter in order to disclose the report contents.

  In addition, regarding the notification that has been notified to the neighboring citizen A of the reporter in step 0205, if the same notification is repeated thereafter, for example, in order to further notify, the setting value 2 In the case where there are more than twice the number of notification calls, further notification is made to neighboring citizens in step 0208.

  In this way, even if the notification content notified to neighboring citizens once, notification to neighboring citizens will be made in a timely manner, such as notifying neighboring citizens at the time when the set value is doubled, tripled, etc .. Is notified of emergency information (step 0208).

  In the third embodiment, as described in the second embodiment, the determination method regarding the duplicated notification call in step 0203 in FIG. FIG. 3 is a flowchart showing the determination process for duplicate notification calls.

  In the figure, when there is a report from the reporter in step 0301, the past report is first compared with the latest report that has not been compared with the report call. Specifically, as shown in step 0302, a report that has already been accepted has not yet been compared with a report call, and the report is selected for the latest report (step 0302). With respect to the notification serving as the comparison control selected in this way, the notification is made to the notification call that has just received the comparison in Steps 0303 to 0305.

  In Step 0303, the difference between the reception time of the notification call and the reception time of the notification selected as described above is calculated, and if the difference is smaller than a preset value, it is determined that the notification has been received at substantially the same timing, The possibility of content matching is high.

  Subsequently, in step 0304, a comparison regarding distance is performed. In the comparison regarding the distance, the position in the notification call and the position of the notification selected as described above are measured, and the distance is calculated from the difference between the measured values. When this distance is smaller than a preset value, it is determined that there is a high possibility that the notification is about the same content, assuming that there is a notification from the same place.

  Subsequently, in step 0305, a comparison is made regarding the subject of the notification call and the notification selected above. The subject here is considered to be, for example, type information relating to the contents of the report registered in step 0202 of FIG. That is, when there is a report from the reporter, the contents are registered according to the report contents. If the subject lines here match, it is determined that there is a high possibility of reporting on the same content.

  As described above, in the determinations in Steps 0303 to 0305, regarding all the reports that match, it is determined that there is an extremely high possibility that the notifications are related to the same content, and the received notification call that is the comparison control is the same as the notification call Register as a report (step 0306). If it is determined that the same call is the same, the count is incremented in step 0204 in FIG.

  In the fourth embodiment, emergency information is actually determined using the numerical values in the tables of FIGS. 4, 5, and 7. FIG.

  FIG. 4 shows examples of various set values, which are set value examples where the set value for the reception time difference is 10 minutes and the set value for the reception distance difference is 1,000 m. FIG. 5 and FIG. 7 show examples of various values of the reception notification, and show the correspondence between the notification call name 0501, reception time 0502, location information 0503, and subject 0504.

  The determination is made according to the flow taken in FIGS.

  First, in the flow of FIG. 2, a report from the reporter is accepted in step 0201, and the report contents are registered in step 0202. Thereafter, as in step 0203, a determination is made as to whether there is a report overlapping with the report call regarding the past report. The determination is made according to the flow of FIG. 3, but here the determination is made with reference to each value of FIG.

  First, in step 0302, the past call is not yet compared with the report call, and the report call with the report closest is selected. That is, in FIG. 2, the report A is selected.

  Subsequently, a comparison of reception times in step 0303 is performed. At this time, since the set value of the reception time in FIG. 4 is described as 10 minutes, it is determined that there is a high possibility that the notifications within 10 minutes are the same notification. Under this condition, the notification call A satisfies the condition within 10 minutes (see FIG. 6), so it is determined that there is a high possibility that the notification call A is the same as the notification call just received.

  Subsequently, in step 0304, a comparison regarding distance is performed. In this comparison, the distance is calculated based on longitude and latitude information. A specific distance calculation method is obtained by using a method such as “Hyubeni distance calculation formula”, for example, and the calculation result is shown in FIG. FIG. 6 shows the relationship between the time difference / distance difference with the reception notification, and shows the correspondence relationship between the notification call name 0501, the time difference 0602, and the distance difference 0603. In this comparison, the notification A cannot satisfy the condition within the set value of 1,000 m in FIG. 4 and is excluded from the candidate target that is the same notification in comparison with the notification call.

  Subsequently, in step 0302, a report call having the latest reception time is selected from the report calls other than report A. In FIG. 5, the report B is selected. Report B is a candidate for the same report call in both the reception time condition in Step 0303 and the distance condition in Step 0304. However, the condition related to the subject in Step 0305 is different from the report call. You will not be a candidate for a call. Eventually, only the notification call C that is selected next satisfies all the conditions of Steps 0303 to 0305 and is determined as the same notification call.

  In addition, as shown in FIG. 7, when the latest report call does not fall within the set value range regarding the reception time shown in FIG. It will be judged as not. That is, when the notification call A in FIG. 7 deviates from the same notification candidate (see FIG. 8), the notification call B also deviates from the same notification call candidate.

0101: Citizens communicating through the same base station as the citizens reporting emergency information 0102: Base stations (main server of mobile phone operators)
0103: Citizen who communicates through the same base station as the citizen who reports emergency information 0104: Citizen who performs notification of emergency information 0105: Facility having emergency information determination unit, emergency route selection unit, emergency information notification unit 0106: Report content The part 0107 for determining whether or not it is emergency information: When the emergency information is notified by the emergency information notification unit, the part 0108 for determining the notification content is determined through the base station.
