Description

The present invention is a position information system that grasps the position of a terminal by using the communication function of a mobile terminal, and a detection system that detects an abnormality in a predetermined area by using a sensor that uses infrared rays, ultrasonic waves, microwaves, or the like. Regarding the location information system integrated with, for example, the location information system useful for grasping the personnel evacuated from the inside of the building to the outside in the event of a disaster such as a fire or an earthquake and supporting rescue activities.

In recent years, a disaster prevention support system has been put into practical use that supports firefighting activities by sending information such as the location of the fire and commands related to firefighting activities to terminals carried by self-defense firefighters based on information from fire receivers when a fire breaks out. Is being done.
As an invention relating to such a disaster prevention support system, a support device and a terminal are provided, the support device transmits position inquiry information to the terminal when receiving abnormality information, and the terminal receives the position inquiry information to provide a satellite positioning system. The position of the terminal is measured and transmitted, and the support device determines whether the position of the terminal is in the facility and stores the determination result information in association with the ID of the self-defense fire brigade member who carries the terminal. Remember in the department. Then, when the stored information indicates that the position of the terminal is in the facility, the support information regarding the abnormality is transmitted to the terminal, and when the terminal receives the support information, the support information is displayed on the display unit. Is known (for example, Patent Document 1).

On the other hand, in the event of a disaster such as a fire or an earthquake, it may be desirable to check if there are any residents in the building who have been late to escape. As an invention relating to such a user location management system, a terminal such as a smartphone carried by a user who uses a building by installing a beacon device in each section such as a room of a building and repeatedly transmitting a beacon signal including a section ID can be used. When the beacon signal is received, a location report including the division ID extracted from the beacon signal and its own terminal ID is transmitted to the server. Then, the server collects and manages the user location information indicating the section where the terminal exists based on the terminal ID and the section ID included in the location report received from the user's terminal, and fires from the fire receiver. It has been proposed that when a detection signal is received, a user terminal located in a fire area is detected from the user location information and output as information of a user who has been delayed in escaping (see Patent Document 2). ).

In addition, the safety of the user who owns the mobile terminal is determined based on the history of the position information before and after the time when the emergency bulletin such as an earthquake is received, and the position of the user of the second mobile terminal is determined to the user of the first mobile terminal. An invention relating to a safety confirmation information providing device that provides information and information on safety has been proposed (see Patent Document 3).

In the first embodiment, as shown in FIG. 4A, the location information server 40 first determines whether or not the beacon information has been received from the mobile terminal 20 (step S20). If the beacon information has not been received (step S20; No), the process ends.
On the other hand, when the beacon information is received (step S20; Yes), the location position of the mobile terminal 20 is calculated based on the received beacon information and the information stored in the database 41 (step S21), and the previous time. It is determined whether or not the position has changed from the position of the above (step S22). Then, when the position is changed (step S22; Yes), it is memorized that the mobile terminal 20 is moving and the mobile terminal has a high carrying rate (step S23), and a predetermined time (for example, 1) is stored. When the position has not changed for time) or more (step S22; No), it is stored that the mobile terminal 20 is non-moving (step S24).

Subsequently, the position information server 40 determines whether or not information indicating whether charging is being received is received from the mobile terminal 20 that has received the beacon signal (step S25). Here, when the charging information is received, it is memorized that the carrying rate of the mobile terminal is low because the charging is being performed instead of moving (step S26). Further, when the charging information is not received in step S25, it is not moving or charging, so it is possible that the mobile terminal is not carried or is carried but not moved. Remember that the mobile rate is "medium" (step S27).
After that, a map of the floor (current floor) where the mobile terminal 20 is located is extracted from the database 41 based on the terminal location calculated in step S21 (step S28), and the location of the mobile terminal 20 is extracted from the extracted map.

Subsequently, the map information (current floor map information) generated in step S29 is transmitted to the mobile terminal 20 and other mobile terminals via the communication network N and the mobile phone base station 30 (step S30). At this time, the information regarding the terminal carrying rate stored in steps S24, S26, and S27 is added and transmitted. As a result, on the display unit of the mobile terminal 20, the map (floor diagram) of the floor (current floor) on which the mobile terminal 20 is located as shown in FIG. 5 shows the portion corresponding to the current position of the mobile terminal 20. A floor map image on which the mark M indicating the mobile terminal 20 is displayed will be displayed. The circled numbers attached to the mark M represent the number of people (the number of mobile terminals) at that location. When the mark M is touched, the state of each terminal (charging, etc.) may be displayed.

Further, as shown in FIG. 6, for example, a symbol that can identify the terminal carrying rate of the terminal is added to the mark M indicating the mobile terminal 20 in the displayed floor drawing. Here, (a) represents a mobile terminal having a high terminal carrying rate, (b) represents a mobile terminal having a "medium" terminal carrying rate, and (c) represents a mobile terminal having a low terminal carrying rate. By performing such a display, the mobile terminal of each mobile terminal can be grasped, and it can be determined that the mobile terminal having a low terminal mobile rate is likely to be misplaced.
Instead of adding symbols as shown in FIGS. 6A to 6C, the mark M is displayed in different display colors when the terminal carrying rate is low, high, and “medium”. You can do it. FIG. 6D is a symbol representing a mobile terminal requesting rescue. The symbols shown in FIGS. 6 (a) to 6 (dc) are examples, and the present invention is not limited thereto. Further, it may be expressed by a numerical value or a character other than a symbol.

ここで、ケース＃３は、端末携帯率が低いので、当該携帯端末は置き忘れである可能性が高い。なお、本実施形態においては、位置情報サーバ４０が携帯端末から充電中か否かの情報を取得して端末携帯率を判断する場合を例にとって説明したが、充電中情報に代えてあるいは充電中情報と共に携帯端末に内蔵されている加速度センサの情報を取得して、所定時間（例えば１時間）以上加速度センサの情報が変化していない場合には移動していないと判定して、端末携帯率を判断するようにしても良い。 Table 1 below shows how to classify the terminal carrying rate for each case in the location information system of the present embodiment.

Here, in case # 3, since the terminal carrying rate is low, there is a high possibility that the mobile terminal is misplaced. In the present embodiment, the case where the location information server 40 acquires information on whether or not the mobile terminal is charging to determine the terminal mobile rate has been described as an example, but instead of the charging information or during charging. The information of the acceleration sensor built in the mobile terminal is acquired together with the information, and if the information of the acceleration sensor has not changed for a predetermined time (for example, 1 hour), it is determined that the mobile terminal has not moved, and the terminal carrying rate. You may try to judge.

Further, the location information server 40 acquires (calculates) the moving distance of the mobile terminal, levels or quantifies the mobile rate based on the information on the moving distance and the charging information, and generates the mobile rate information. Is also good. Here, as the information regarding the moving distance of the mobile terminal, for example, the moving distance of the mobile terminal within a predetermined time calculated based on the information from the acceleration sensor or the gyro sensor provided in the mobile terminal or the position information by the GPS function, or the predetermined time. Information on the number of beacons received within (the larger the number, the larger the travel distance), etc. can be considered. In addition, processing such as changing the level or numerical value of the mobile rate may be performed according to the length of time that the mobile terminal is not moving.
By leveling or quantifying the mobile rate as described above, the mobile rate can be displayed in four or more stages, which is more than the three stages in the above embodiment, or the mobile rate can be displayed as a percentage. ..

Next, the processing of the location information server 40 in the second embodiment will be described.
In the following description, among the mobile terminals 20 existing in the fire-breaking building (the building in which the fire detector 50 is operating), the administrator-authorized terminal owned by the administrator is referred to as a "special terminal" and is inside the fire-breaking building. Among the mobile terminals 20 existing in the above, a mobile terminal 20 other than an administrator-authorized terminal is referred to as a "general terminal", and a person who possesses a general terminal is referred to as a "general terminal user". Here, the "administrator authority terminal" may be a mobile terminal 20 possessed by the self-defense fire brigade commander, or a stationary PC terminal deployed at the disaster prevention center. In the explanation, it is divided into two groups, "administrator authority terminal" and "general terminal", but it does not have to be limited to the two groups. For example, a "self-defense firefighter terminal" possessed by a self-defense firefighter.

The self-defense fire brigade commander and the disaster prevention center are notified in advance of the login ID and password for administrator authority, and the mobile terminal 20 for which the login ID and password for administrator authority are set at the time of installation is registered as an administrator authority terminal. NS. The mobile terminal 20 for which a login ID and password other than those for administrator authority are set at the time of installation is registered as a mobile terminal 20 other than the administrator authority terminal. As a result, the location information server 40 can acquire the information of the mobile terminal to which the support information is transmitted in the event of a fire.

In the location information system of the second embodiment, when the fire information server 80 receives fire information (information including fire occurrence location information, occurrence time information, etc.) from the fire receiver 60, it is transmitted together with the fire information. The building identification information (building name, address, etc.) corresponding to the identification information (receiver ID) of the fire receiver 60 is acquired from the database 81, and the fire information is acquired together with the acquired building identification information on the location information server 40. Send to.
When a fire breaks out in any of the plurality of buildings managed by the location information server 40 (when the fire detector 50 is operating), the location information server 40 is a fire-breaking building (fire detector) based on the beacon information from the mobile terminal 20. The mobile terminal 20 located in the building where 50 is operating) is specified.

The process shown in FIG. 4A is a normal process in the second embodiment, and is a process executed toward the mobile terminal 20 other than the special terminal and the general terminal. Therefore, even if a fire breaks out in any of the plurality of buildings managed by the location information server 40, normal processing is repeatedly executed at a fixed cycle for the buildings without a fire, and the location information server 40 If a fire breaks out in any of the multiple buildings managed by the company, the fire treatment described below (FIG. 4 (b)) is executed, and the normal fire treatment shown in FIG. 4 (a) is performed. Time processing (step S36) is executed.

Next, an example of the procedure for fire processing executed by the control unit of the location information server 40 will be described with reference to the flowchart shown in FIG. 4 (b). The fire processing of FIG. 4B is started by, for example, the fire information server 80 receiving information notifying the occurrence of a fire from the fire receiver 60 and transmitting the fire information to the location information server 40. It should be noted that steps S31 to S35 of this flowchart are processes executed toward the special terminal and the general terminal, and step S36 of the fire processing is the other mobile terminal 20 (mobile terminals other than the special terminal and the general terminal). It is a process executed toward 20).

In the fire processing of FIG. 4B, the location information server 40 first extracts a map of the fire floor from the database 41 (step S31), and plots the location of the fire on the extracted map (step S32).
Next, the location positions of the special terminal and the general terminal are calculated based on the beacon information from the special terminal and the general terminal and the information stored in the database 41 (step S33). Subsequently, map information is generated by plotting the location of the terminal located on the fire floor on the map on which the location of the fire is plotted (step S34). At this time, the mobile terminal may generate map information marked so as to be distinguishable from other terminals. Further, in order to indicate how many people are present, each mark may be displayed by adding a number corresponding to the number of mobile terminals 20 that have transmitted the same beacon information.

Subsequently, the map information (fire floor map information) generated in step S34 is transmitted to the special terminal and the general terminal via the communication network N and the mobile phone base station 30 (step S35). As a result, the floor diagram image of the fire floor on which the fire mark F and the terminal marks M1 and M2 are attached to the display unit of the special terminal and the general terminal, for example, the location of the fire and the location of the terminal as shown in FIG. Will be displayed. In FIG. 7, the mark (M2) with a thick circle indicates the place where the user is.

After that, the same processing as the normal processing shown in FIG. 4A is executed (step S36), and the process returns to step S32. By the normal processing in step S36, the floor diagram image as shown in FIG. 5 showing the mark M of the location position of the own terminal is displayed on the display unit of the general terminal. In addition, a symbol indicating the carrying rate of the mobile terminal is added to each mark. The method of classifying the terminal carrying rate for each case in the location information system of the present embodiment is the same as in Table 1 in the event of a fire and in normal times. Further, when a fire is occurring on the same floor, information on the evacuation direction and map information with a fire mark may be transmitted and displayed in addition to the location mark M of the own terminal.

Although not shown in FIG. 4, the location information server 40 receives beacon information from any beacon or when it is determined that the mobile terminal 20 is receiving beacon information from the portable beacon 10B. If it is determined that the mobile terminal is not, it is highly possible that the mobile terminal is outdoors, so it may be determined that the mobile terminal has a high mobile rate regardless of the presence or absence of charging information.
Further, since the mobile terminal that has reported the completion of evacuation has been evacuated by the location information server 40, even in a situation where the location cannot be grasped, for example, the setting for providing location information is turned off on the mobile terminal side. , "Mobile rate: high" may be determined and displayed on the display unit. By displaying the terminal mobile phone rate with a symbol as described above, it is possible that the mobile terminal displayed on the fire occurrence floor is misplaced by self-defense firefighters and disaster prevention centers who are active in the event of a fire. You can make a judgment and carry out efficient rescue activities.

Further, in the position information system of the present embodiment, when a fire occurs, in the floor diagram image showing the mark M of the location position of the mobile terminal other than the special terminal and the general terminal, as shown in FIG. 8, outdoors or The temporary evacuation site G and the number of people who have completed evacuation outside the monitoring area are displayed. Further, when there are a plurality of temporary evacuation sites, each temporary evacuation site is linked to the portable beacon carried into the temporary evacuation site and registered in the database 41 of the location information server 40, so that each temporary evacuation site can be registered on the map. The number of people who have completed evacuation can be displayed in a graspable manner.

Further, in the location information system of the present embodiment, the location information application displays an input screen on which the terminal holder can input information on the physical and mental condition (safety, injury, waiting for emergency transportation, etc.) and a rescue request. It has a function.
Specifically, as shown in FIG. 7, an input button image Bsos for requesting rescue is displayed in the upper left of the map display screen, and when the mobile terminal holder touches this input button image Bsos with a finger, In normal times, the screen as shown in FIG. 9A is displayed. If you select "Disaster prevention center" or "Nearby person" on this screen, the call device of the disaster prevention center or a mobile terminal existing nearby will be called and you will be able to make a call. When "Nearby" is selected, the location information server 40 searches the database 41 to find a mobile terminal receiving radio waves from a beacon installed on the same floor as the mobile terminal. A call is made possible by acquiring the telephone number or address of the terminal and establishing a communication path.

On the other hand, in the event of an abnormality such as a fire, a screen as shown in FIG. 9B is displayed on the screen of a general mobile terminal, and the mobile terminal owner calls the disaster prevention center or inputs the degree and status of injury. Can be done. In addition, a screen as shown in Fig. 9 (c) is displayed on the screen of the mobile terminal of the self-defense firefighter, and the disaster prevention center can be called by using the mobile terminal of the self-defense firefighter, and the specific content of the request. You can enter the status.
When any of the items is selected on the screen of FIG. 9B or FIG. 9C, the mark M indicating the mobile terminal on the map screen has the “SOS” symbol as shown in FIG. 6D. It is added and displayed, and when this mark is touched with a finger, the degree and status of the injury entered in the rescue request and the specific content of the request are displayed on the screen as shown in FIG. 9 (d).
As described above, in the position information system of the present embodiment, the mobile terminal can be used to support the rescue activity when an abnormality occurs.

Further, in the position information system of the present embodiment, the evacuation completed mobile terminal (user) list is obtained from the identification information of the stationary beacon 10A and the portable beacon 10B and the information of the mobile terminal 20 that has transmitted the identification information. It may be possible to display a list of mobile terminals (users) whose evacuation has not been completed. As a result, it is possible to quickly grasp the evacuees when there are multiple temporary evacuation sites and information such as who has not completed evacuation. Here, when the monitoring target is an office building, an attendance system may be connected to the location information server 40 so that attendance / vacation information can be acquired.

As a result, it is possible to avoid mistakenly grasping an employee who is outside the company as a person who is late to escape from the list of mobile terminals (users) whose evacuation has not been completed. It should be noted that each user may be able to input information on the physical and mental conditions of himself / herself and others (safety, minor injury, waiting for emergency transport, emergency transport completed, etc.) using a mobile terminal. As a result, the status of each person can be grasped on the floor map or the list of mobile terminals (users) whose evacuation has been completed, which can be used for prompt first aid and determination of work priority. can.
