Description

  In the present invention, a party (hereinafter referred to as a notifier) registers a still image / moving image around a notifier and a surrounding situation such as an incident occurrence position / map image, sound, and an incident occurrence time, and is registered in advance at a time. The present invention relates to a method for communicating with each other without using an information management center to calculate the distance to the portable information terminal group, and for notifying the portable information terminals within a set distance in a distributed manner.

  Conventional danger notices, which are one of the surrounding situation notices, have been centrally managed at the security control center of the security company via the emergency button of the warning device with GPS function that the security company lent to the contractor. Since the security guards went to rescue after receiving the danger information at the crime prevention control center, there was a difficulty in emergency response. In addition, it is necessary to secure security guards and establish a base for security guards to stay in place, and if the improvement of services is pursued, the centralized risk notification method may become a major issue.

  In addition, considering the security of local residents, local governments must install a large number of security cameras. Just installing it is not safe. For example, if there is moving image data that is likely to be displayed on thousands of security cameras where the corpse has been abandoned, the location and time of the crime cannot be identified at the initial action stage. The moving image data must be exhausted. Moreover, in order to construct such a crime prevention system, a large amount of crime prevention costs such as installation costs for security cameras and monitor rooms and development costs for image analysis are required.

  Patent document 1 and patent document 2 were mentioned as a notification system using a portable information terminal related to the present invention. In Patent Document 1, voice / image / position data is transmitted from a mobile phone to a crime reporting server, and danger information is distributed to all notification destinations registered therein. Distribution here is a centralized type managed by a crime reporting server.

  Patent Document 2 describes that the group users are registered in advance in the information providing server, and the information providing server always knows the location information of the user's mobile terminal and approaches within a predetermined distance. The providing server automatically notifies the user. The automatic notification here is also a centralized type managed by the information providing server.

  According to the portable information terminal, the surrounding situation notification application program, and the surrounding situation notification system according to the present invention, it is not a centralized type centering on the crime prevention control center and the information management center, but a danger is encountered or a danger is expected. It is a distributed type in which the notifier is the main, and can notify the surrounding situation of the notifier to a group of pre-registered portable information terminals to protect the notifier himself.

It is a conceptual diagram in which a notifier distributes surrounding situations in a distributed manner. It is a conceptual block diagram which shows the structural example in the notifier side and the to-be-notified person side of a distributed peripheral condition notification. It is a figure which communicates GPS position information and a notifier distributes a surrounding situation to a notified person in a distribution range in a distributed manner. It is a block diagram which shows the structural example in the notifier side and the to-be-notified person side of the distributed peripheral condition notification in a delivery range. It is a block diagram which shows the detailed structural example by the side of a notification person. It is a block diagram which shows the detailed structural example by the side of a to-be-notified person. It is a figure which shows the condition where the user who is a to-be-reported person registers instead of a notifier user. It is a figure which shows the preparation procedure of a terminal database, and the display list | wrist of a notified person. It is the example which displayed on the screen the peripheral condition on the notifier side and the specific information of the rescuer. It is the example which displayed the peripheral condition and rescuer in the to-be-notified person side on the screen.

  An embodiment of the present invention will be described in detail. When the notifier clicks the icon of the mobile application on the home screen of the notifier's mobile information terminal or the icon substitute operation button (a predetermined condition is satisfied), the camera is activated. Other portable information terminals pre-registered in one's own portable information terminal by grouping peripheral situations such as still images / moving images, incident occurrence location / map image, sound, incident occurrence time, etc. To be distributed.

  However, for the click (establishment of the predetermined condition), the statistical value of the brightness histogram obtained from the image around the notifier, the volume / sound quality of the surrounding noise, the heart rate / pulse rate, body temperature, etc. of the notifier This includes the case where the signal emitted by the body is constantly measured and the operation button is automatically activated when the signal deviates from the predetermined threshold value. The subsequent clicks are the same except for the click of the rescue call button 60.

  In addition, the mobile application icon or the icon substitute operation button needs to be arranged in a place where it can be operated immediately. For example, the icon may be displayed with priority on the home screen of the portable information terminal, or an operation button dedicated to the peripheral notification application may be attached to the portable information terminal.

  The portable information terminal of the present invention is further provided with a GPS function. The control of whether transmission is possible or not is determined by the distance comparison means by receiving GPS position information from another portable information terminal.

  FIG. 1 is a conceptual diagram in which a notifier distributes surrounding situations in a distributed manner. In the figure, a plurality of users including Mr. A and Mr. B are notified persons registered in the terminal database 106.

  Further, although the notifier is arranged at the center in the figure, it is naturally possible that Mr. A or Mr. B becomes the notifier. At that time, the notifier at the center of the figure changes its position and quickly changes into a notified person. In other words, the customer is replaced. Such a reversal of position cannot be achieved with a centralized system.

  FIG. 2 is a conceptual block diagram illustrating a configuration example on the notifying party side and the notified party side of the distributed peripheral situation notification. The left side of the figure is the notifier side, and the right side is the notified party side.

  First, on the left side of the figure, the notifying person's surrounding situation obtained by the surrounding situation obtaining means 108 is temporarily stored in the surrounding situation saving unit 110, and the surrounding situation is displayed by the surrounding situation display means 109 on the notifier's portable information terminal. Display on the screen. Simultaneously with the display, the surrounding situation is sent from the transmission unit to the notified person registered in the terminal database 106.

  One of the merits of transmitting the surrounding situation will be described below. If the notifier is highly likely to encounter danger, the surrounding situation of the notifier until reaching the place where the possibility is high should be set each time if manually and continuously in advance. The notification mode can be transmitted to a group of portable information terminals registered in advance by setting the continuous mode by the first click. This makes it possible to take safety measures in case of an emergency. That is, if the surrounding situation is transmitted continuously, a security camera can be substituted. As a simple transmitter for recording equipment such as drive recorders and body cameras, it is possible to continuously transmit the surrounding situation of the site. Therefore, it is possible to predict a route toward the scene to meet a dangerous person, or to leave a moving route even if an unexpected crime is met.

  In addition, since the notifier himself / herself transmits, the crime place and the route to the crime place can be specified, so it is not necessary to specify the crime place and time from a large amount of moving image data possessed by many security cameras. Since it is not necessary to install many security cameras for 24-hour monitoring, it is possible to deal with regions with low population density.

  Returning to FIG. Registration of the specific information of the notified person in the terminal database 106 differs depending on whether or not the portable information terminal is managed (see FIG. 7) by an organization such as an educational institution. The notified person registration means 103 on the left side of the figure does not consider portable information terminal management in the organization. From the registration screen of the notifier's portable information terminal, the portable information terminal of the notified person is registered. However, since manual input is troublesome, once registered in the own mobile information terminal, each other's unique information registered in advance by communication between the mobile information terminals can be received by the own mobile information terminal, You can also register by sending.

  In addition, the e-mail address of a desktop or notebook personal computer without a GPS function can be registered as specific information. Therefore, if an e-mail address for emergency contact of a security company is registered, a small and inexpensive security system can be constructed.

  In addition, if the surrounding situation is sent to a personal computer at home through an e-mail address, it is possible to leave a footprint of the accident site even if an unexpected crime is encountered.

  On the right side of FIG. 2, the surrounding situation from the notifier is received by the receiving unit 101a, the surrounding situation is saved in the surrounding situation saving unit 110a, and at the same time, the surrounding situation is displayed by the surrounding situation display unit 109a. Display on the terminal screen. The configuration on the right side of the figure is indicated by a dotted line on the left side of the figure in order to indicate the possibility of the position change between the notifier and the notified person.

  FIG. 3 is a diagram in which GPS position information is communicated and the notifier distributes the surrounding situation to the notified person in the distribution range in a distributed manner. The notifier distributes the surrounding situation to the notified person in the distribution range determined by the set distance. If the vehicle is used, it can run about 50 km in 30 minutes. Therefore, it is within the assumed range to set the set distance including the notified persons 100 a and 100 b from the notifying person to 50 km with the notifying person 100 as the center.

  When the portable information terminal 100a of the person to be notified (Mr. A) receives the position information request signal from the notifier 100, it returns the GPS position information at the time of reception to the notifier.

  FIG. 4 is a block diagram showing a configuration example on the notifier side and the notified party side of the distributed peripheral situation notification in the distribution range. In addition to the conceptual block diagram of FIG. 2, positioning means for the current position by GPS is provided, and by exchanging GPS position information with other portable information terminals, the surrounding situation is sent to the portable information terminals within a set distance. . As in FIG. 2, the left side of the figure is the notifier side, and the right side of the figure is the notified party side.

  All the distance flags 32 (FIG. 8) are reset when the position information request signal is clicked for the first time when the mobile application icon or the icon substitute operation button is clicked or when both the notifier and the notified person move. When this is done, first, the position information requesting means 111 on the left side of FIG. This is to obtain distance information from other portable information terminals.

  Similarly, on the left of the figure, the notifier's surrounding situation obtained by the surrounding situation obtaining unit 108 is temporarily stored in the surrounding situation storage unit 110, and the surrounding situation display unit 109 displays the surrounding situation on the screen of the notifier's portable information terminal. Is displayed (see FIG. 9A).

  The peripheral situation is selected and transmitted by the following distance comparison means to the portable information terminal registered in the terminal database 106.

  The selection of the portable information terminal starts when the position information request signal is sent from the transmission unit 102. Transmission is performed to all portable information terminals in which the selection flag 31 (FIG. 8) in the terminal database 106 is in the ON state.

  Next, the position information request signal is triggered and received by the receiving unit 101a on the right side of the figure, and is received by the receiving unit 101 on the notification side via the position information communicating unit 104a and the transmitting unit 102a. The distance obtained by 104 and the distance calculation means 105 is first stored in the terminal database 106. A procedure is performed in which the portable information terminal within the set range is selected by the distance comparison means 107 with the set distance. When the mobile application is activated, if the distance flag is turned on after obtaining the distance information, the surrounding situation is immediately transmitted.

  Since the peripheral status is notified to the portable information terminals within the set distance in a distributed manner, the registered person to be notified who is near the notifier can quickly rush to the place where the incident occurred.

  In addition to the position information request signal, the person to be notified also receives the surrounding situation of the notifier. In that case, on the right side of the figure, the surrounding situation is received by the receiving unit 101a, and the surrounding situation is saved in the surrounding situation saving unit 110a, and at the same time, the surrounding situation (on-site still image 50, on-site map image 51, time 52, the current position 57) is displayed on the screen of the personal information terminal of the person to be notified (see FIG. 10) by the surrounding state display means 109a.

  If the rescue call button 60 on the display screen is clicked, the unique information of the notified person is returned by the unique information return means 119a. The return of the unique information is not performed by the conventional danger notification method. Here, the rescue call button is related to claims 4 and 9 of the claims. The same applies to the rescue call button and the rescuer in the following description of FIGS. 5 and 6.

  When notifying the notifier of the unique information of the person to be notified by the unique information return means, it is not necessary to send the unique information to an acquaintance / friend. However, it may not be possible to determine whether the notifier is a rescuer. For example, there is a security guard who rushes by emergency contact of a contracted security company. In this case, the security guard's unique information is required.

  FIG. 5 is a more detailed block diagram showing a configuration example of the notifier side on the left side of FIG. Clicking on the mobile application icon or icon substitution button activates the camera. A still image / moving image 114 and a map image 115 around the notifier are temporarily stored in the memory 117, and image processing is performed so that position information is arranged in the map image. Next, the image, the position information, time, and the like are stored in the surrounding state storage unit 110. Such information is displayed by the surrounding state display means 109. Simultaneously with the display, not only the image but also the surrounding situation such as the event occurrence position 116, the sound, and the event occurrence time 113 is stored in the buffer 118. This is for displaying information such as the image 50, the map 51, the time 52, the rescue call button 60, the position information 57, and the rescuer 53 shown in FIG.

  Also in the rescuer storage unit 112 in which the name of the rescuer is stored, it is checked whether or not there is a rescuer when transmitting the surrounding situation, and if there is a rescuer, it is additionally stored in the temporary storage 118 in the buffer. Is done.

  Thereafter, all of them are transmitted from the transmission unit 102 to other portable information terminals at once.

  There are two types of information in the information entering the receiving unit 101. One is position information 104a (FIG. 6) in response to the position information request signal. The other is unique information of the name / face image / position information 119a (FIG. 6) and arrival time 120a (FIG. 6) of the person to be notified which is received when the rescue call button is clicked.

  In the case of the position information 104a (FIG. 6), the distance obtained by the distance calculation means 105 based on the position information is stored in the terminal database 106. After that, the distance comparison means 107 with the set distance controls the transmission unit 102 such that transmission is possible if the portable information terminal is within the set range, and transmission is not possible if it is outside the set range.

  In the case of the rescue call button 60, the name of the rescuer is stored in the rescuer storage unit 112.

  Further, the unique information of the name / face image / position information 119a (FIG. 6) and the arrival time 120a (FIG. 6) of the notified person are stored in the surrounding state storage unit 110. When the rescuer 53 is displayed on the surrounding situation display means 109 (FIG. 9A), if the rescuer 53 is clicked, the name 54, the face image 55, and the caller position 58, which are unique information of the rescuer, are displayed. The arrival time 56 and the like are further presented (FIG. 9B).

  FIG. 6 is a more detailed block diagram showing an example of the configuration of the notified person on the right side of FIG. In FIG. 10, the surrounding situation from the notifier received by the receiving unit 101a is temporarily saved in the surrounding situation saving unit 110a. Simultaneously with the saving, the surrounding situation is displayed on the portable screen by the surrounding situation display unit 109a as shown in FIG. Is displayed.

  If the rescue call button 60 in the figure is clicked, the unique information of the name / face image / position information 119a of the person to be notified and the arrival time 120a are transmitted to the notifier.

  For the caller position 58 (FIG. 9B), the map information is extracted from the surrounding state storage unit 110a sent by the notifier, and the caller position is given by image processing. If an acceleration sensor is attached to the portable information terminal, the arrival time is calculated 120a from the speed obtained by integrating the distance and acceleration between the notifier and the notified person over time, and the name 54, face image, which is unique information of the notified person, In accordance with 55, the map image to which the arrival time 56 and the caller position are assigned is also stored in the buffer in the temporary storage 118a and sent from the transmission unit 102a.

  As one example of not using the relief call button 60, there is a method of using a surrounding notification in an area where the neighborhood level is small. For example, an image of an elderly person who is lost and cannot return home and a location / map image are sent to a pre-registered mobile information terminal group of a part of local residents who have accepted the reception. be able to. As described above, since the location of the elderly person can be notified to the local residents who are in need of nursing care, the service of the surrounding situation notification system can provide the local residents with peace of mind.

  Another example is the usage of sharing the surrounding image and whereabouts of the suspect with the investigation team while the police officer can track the suspect because the surrounding situation and location / map image can be distributed. . By simply attaching a mobile application icon or icon substitute operation button to the mobile information terminal for notification of the surrounding situation, the surrounding situation of the suspect is appropriately sent to the investigation team, and the information can be quickly shared with the team. .

  This is a modification of the previous case. When building a project team, for example, when constructing a plant, highway, or large building, it is necessary to always share information between members in order to quickly grasp the progress of the construction and make adjustments between members. . By using a design drawing instead of a map image, the location information of the notifier in the drawing and surrounding images are sent to the project team, so that the construction progress can be shared with the team.

  FIG. 7 is a diagram illustrating a situation in which a user who is a notified person registers instead of a notifying user. In order to register the person to be notified, a method in which the person to be notified registers the person to be notified from the registration screen of the portable information terminal like the person to be notified registration means 103 on the left in FIG. 2 and FIG. As described above, there is a method in which a guardian registers himself / herself as a notified person on behalf of a notifier, a kindergarten / student / student.

  The latter registration method requires the terminal management server 20 that can communicate with the mobile information terminal group. The terminal management server includes a terminal management database 24 for storing the terminal ID of the portable information terminal and the specific information of the notified person corresponding to the terminal ID (FIG. 7A). The terminal ID is an ID code for identifying the portable information terminal.

  When a guardian who is a notified person is registered as a user in FIG. 5B, the terminal ID of the notified person is assigned to 0120 in the user registration unit 22 in FIG. . Thereafter, the unique information 25 of the notified person and the user name 26 of the notifying person are transmitted to the terminal management server (FIG. 5A).

  A state where the registration information from the terminal ID 0120 to the terminal management server is registered in the terminal management basic ledger ((e) in the figure) is indicated by ● in FIG. Two notifier users 1160055 and 1160061 are stored in the notifier terminal ID, which is the final item of the terminal ID 0120, with the terminal IDs 0055 and 0061 assigned to the notifier user. Note that the notifier terminal ID, which is the final item of the “school-related” specific information in the upper part of FIG. 9 (e), is 0000 in order to distinguish it from the specific information of “register from mobile” in the lower part. .

  FIG. 8 is a diagram showing a procedure for creating a terminal database and a display list of notified persons. (A) and (b) in FIG. 7 show in detail the procedure of creation from the terminal management basic ledger 23 to the terminal management database 24 in FIG. 7 (a). Further, FIG. 8C shows a procedure for creating a terminal database 106 specific to each portable information terminal, and finally FIGS. 9D and 9E show a display list of two types of notified persons. Yes. The two types are a first terminal database that is not updated during the required number of years of study determined by the educational institution and a second terminal database that is updated each time the specific information of the notified person is registered. 8A and 7E are the same terminal management basic ledger.

  The unique information of “school relation” in the upper part of FIG. 8A is set by each educational institution such as a junior high school and a university. “Notifier terminal ID 0000” 27, which is the last item, means that no notified person is stored for each terminal ID (notifier). Further, when the information is rearranged in ascending order by the notifier terminal ID, the unique information of “school relation” having the notifier terminal ID of 0000 is not replaced, and FIG. This can be done because if the registered person is registered from the mobile screen, the specific information of the notified person is added from the final record of the terminal management basic ledger where the upper “school relation” exists, This is because it is registered in the “Register from mobile” section.

  However, “notifier terminal ID 0055, 0061” 28 in FIG. 9A is divided into two, and in FIG. 7B, “terminal ID 0120” is stored as the notified person for the notifier terminals ID 0055 and 0061. Yes. That is, the registrant himself / herself is registered in the terminal database 106 of the inexperienced notifier as a notified person on behalf of an inexperienced notifier who handles the portable information terminal. This relates to claim 13 of the claims.

  FIG. 8C shows the terminal database 106 in which only the “notifier terminal ID 0060” 29 shown in FIG. 8B is extracted. There are more items in the terminal database than those in the terminal management database 24, and items of a lock 30, a selection flag 31, a distance number, and a distance flag 32 are added.

  Four items will be described. If the notifier thinks that the surrounding situation of the notifier may be transmitted, the notifier turns on the selection flag 31. The number of distances is the distance from another portable information terminal obtained from the distance calculation means. The distance flag 32 is turned ON if it is within the set distance range.

The locker turns on the lock 30 when the lock 30 is always transmitted even outside the set distance range. This is because all the distance flags 32 must be reset to OFF after the set time has elapsed since the notifier and the notified party do not always stay in the same place. Therefore, the lock is turned on so that the distance flag is not reset. When the distance flag is reset, GPS information is obtained through communication with all portable information terminals whose selection flag 31 is in the ON state, and the distance flag is reset.

  FIG. 8D shows that the unique information of “school relation” in the upper part of FIG. 8C has been transferred to the portable information terminal. The terminal database of “school relations” is not updated until graduation. In other words, it is a one-time transition. FIG. 8E shows the transfer of specific information of “family / friends / security company” in the lower part of FIG. It is updated each time a notified person is added or deleted.

  FIG. 9 is an example in which the surrounding situation on the notifier side and the unique information of the rescuer are displayed on the screen. FIG. 4A shows an example in which the notifier's peripheral situation on the notifier side is displayed on the screen. Since the notification of the surrounding situation is distributed, it is naturally possible to change the position even on the notifier side and receive the surrounding situation of the notified person from another portable information terminal. Here, since it is not the person to be notified, that is, since the surrounding situation from the person to be notified has not been received, it is not currently displayed. Similarly, in FIG. 10, which is an example in which the surrounding situation and the rescuer on the notified person side are displayed on the screen, the surrounding situation when the notification person side is displayed is not currently displayed.

  According to this embodiment, when the danger of the notifier approaches, it is possible to immediately notify the family / friends of the surrounding situation of the notifier, and the security company if contracted. The decentralized present invention, which is mainly a notifier, can build an inexpensive crime prevention system in the field of security and crime prevention, and is expected to have a great effect as a deterrent for crimes triggered by resentment and hatred in today's society. it can.
