Description

  The present invention is a communication system and method suitable for use in making a risk prediction at the time of going to and from school, etc. of a monitoring target person such as a child or a rush request to a crime prevention cooperator in an emergency using a communication terminal. Regarding the program.

  In recent years, there have been many incidents in which children who are going to and from school are attacked or taken away by suspicious individuals. There is a growing expectation for a support system that ensures the safety and security of children socially.

  As one of such support systems, there is one that automatically detects that an intruder has been entered and notifies a supervisor (Patent Document 1). The system described in Patent Document 1 acquires the position of the monitoring subject by radio waves transmitted from a PHS (Personal Handy-phone System) terminal, detects that the monitoring subject has entered the danger area, Notify the supervisor.

In addition, as another support system, there is one that notifies the surroundings when an abnormal situation occurs (Patent Document 2). The system described in Patent Document 2 notifies the abnormality when the mobile terminal determines the normality of the movement pattern based on the position information and the step count information and determines that the movement pattern is abnormal.

(B) Predicting that the child is heading to the dangerous area (that is, when detecting an abnormal state of heading to the dangerous area), notifies the guardian of emergency information indicating that fact.
(C) Detecting that the child has entered the dangerous area (that is, when detecting an abnormal state that the child has entered the dangerous area), notifies the guardian of emergency information indicating that fact.
[4] Provide information on security cooperators near children to parents.

  Next, the configuration and function of each device in the system configuration diagram of FIG. 1 will be described.

  The GPS satellite 1 transmits a radio wave for detecting a position.

  The GPS mobile phone 2 is used by a crime prevention collaborator who runs to the child or the place of the child. It has a function of receiving a radio wave from the GPS satellite 1 or a mobile phone base station (assumed to be included in the network 5) and calculating latitude and longitude. This function makes it possible to calculate latitude and longitude using radio waves from a mobile phone base station even in an indoor, building, or underground mall where GPS signals are difficult to reach. The GPS mobile phone 2 has a call function as a mobile phone. It also has a network connection function such as the Internet. It also has an e-mail (hereinafter referred to as e-mail) transmission / reception function. It also has a Web access function by a browser.

  The mobile phone 3 is a normal mobile phone having a call function and an Internet connection function. It is used when parents receive warning emails or check the location of children or security cooperators.

  The communication terminal 4 such as a telephone or a personal computer is used when the guardian receives a warning mail or confirms the position of the child or the crime prevention cooperator. This communication terminal 4 is used in the same manner as the mobile phone 3.

  The network 5 is a communication network such as a fixed telephone network, a mobile phone network, and the Internet, and connects each device by wired or wireless communication.

  The server 6 is a server that collects, stores, and analyzes position information of the GPS mobile phone 2. Its main functions are as follows. It detects that the movement of the child is significantly different from the normal movement, and notifies the guardian (corresponding to [3] (A) above). Predict that the child is heading to the danger area and notify the guardian (corresponding to [3] (B) above). The GPS detects that the child has entered the dangerous area and notifies the guardian (corresponding to [3] (C) above). Analyze the movement pattern of security cooperators, and provide information for parents to ask the security cooperators near the children to rush.

  The map service 7 is a service provided by a map company or the like (a Web service that provides information by accessing from a browser or software obtained by expanding the browser). By accessing information such as latitude and longitude as parameters, map information (map image information), a straight line between two points or the shortest distance on the route (distance of the shortest route for pedestrians or cars), address text information Etc. More specifically, in the present embodiment, the map service 7 has a URL of a predetermined server of the map service 7 including information indicating the longitude, latitude, and what information is requested as a URL (Uniform Resource Locator) parameter. Depending on the access, the location of the child or the security cooperator is mapped to the map, or the distance is calculated by calculating the shortest path between the two points. The address is calculated from the latitude and longitude.

  The position search service 8 is a service for searching the position of the GPS mobile phone 2. Provided by mobile phone companies. The location search service 8 provides latitude / longitude information of the GPS mobile phone 2 in response to an access using the phone number of the GPS mobile phone 2 as a parameter.

Next, the functional details of the server 6 in FIG. 1 will be described with reference to FIG.
FIG. 2 is a functional block diagram of the server 6.
The server 6 includes a computer and peripheral devices for storage, communication, display, and the like, and executes a program for realizing each function on a predetermined OS (Operating System). Each function is provided. FIG. 2 shows each function divided into blocks. The server 6 shown in FIG. 2 includes a network connection unit 601, a location information collection unit 602, a location information history analysis unit 603, and a difference detection with normal movement. Unit 604, dangerous area approach prediction unit 605, dangerous area approach detection unit 606, mail transmission unit 607, 3PCC (3rd Party Call Control) unit 608 and rush request processing unit 609, and predetermined storage means A personal information table for children 610, a personal information table for crime prevention cooperators 611, a position information history 612, a movement history table 613, and a danger area definition table 614 are stored.

  A network connection unit 601 shown in FIG. 2 is connected to the network 5 and can use the map service 7 and the location search service 8 in each functional block in the server 6. The location information collection unit 602 repeatedly collects location information of the GPS mobile phone 2 of the child and the crime prevention collaborator and accumulates the location information history 612. The position information history analysis unit 603 analyzes the position information history 612, and based on the accumulated position information history 612 for a predetermined period, a movement including information of a plurality of movement histories with one pattern from the movement start to the movement end. A history table 613 is created.

  The normal movement difference detection unit 604 detects whether or not the movement of the child is significantly different from the normal movement. That is, the difference detection unit 604 from the normal movement includes the position information recently accumulated in the position information history 612 (for example, position information whose elapsed time from the date and time measured by the time measurement unit is within a predetermined time) and the movement. The movement history pattern included in the history table 613 is compared, and when the comparison result satisfies a predetermined condition, an abnormal state in which the movement of the child is significantly different from the normal state is detected. The dangerous area approach prediction unit 605 predicts that the child is heading to the dangerous area. That is, the dangerous area approach prediction unit 605 determines that the child's GPS mobile phone 2 is heading to the dangerous area defined in advance in the dangerous area definition table 614 based on the position information recently accumulated in the position information history 612. Detects an abnormal condition that a child is heading to a hazardous area when predicted. The dangerous area approach detection unit 606 detects that the child has entered the dangerous area using the GPS. That is, the dangerous area entry detection unit 606 indicates that the child's GPS mobile phone 2 has entered a dangerous area defined in advance in the dangerous area definition table 614 based on position information recently accumulated in the position information history 612. When detected, an abnormal state that the child has entered the danger area is detected.

  Moreover, the mail transmission part 607 transmits mail to a guardian or a crime prevention cooperator. That is, when the abnormal state is detected by the difference detection unit 604 from the normal movement, the dangerous area approach prediction unit 605, or the dangerous area entry detection unit 606, the mail transmission unit 607 is connected to the guardian's mobile phone 3 or communication terminal. 4 or further notify emergency information indicating that an abnormal state has been detected to the GPS mobile phone 2 of the crime prevention cooperator.

  The 3PCC unit 608 performs 3PCC on a SIP (Session Initiation Protocol) server. That is, the server 6 of the present embodiment has a SIP server function. Note that 3PCC is different from normal call connection in which a call is received from a call terminal, and a third-party device such as a computer device connected to a network is used for both calls. This is a control method in which a call is made to a terminal and a call connection is established between the two in response to an incoming call. When using 3PCC, the SIP server calls each of the guardian's mobile phone 3 or communication terminal 4 and the child's or security cooperator's GPS mobile phone 2 and waits for an incoming call. When a call is received, a call connection is established between the parent's mobile phone 3 or communication terminal 4 and the child's or crime prevention collaborator's GPS mobile phone 2. In this case, both do not need to perform an operation for making a call (outgoing operation), and a call connection between the two is established only by responding to a call from the SIP server (receiving operation). That is, both do not need to make a phone call, and only the operation of receiving a call connects the two.

  The rushing request processing unit 609 accepts a rushing request from a guardian and provides information on a crime prevention cooperator near the child.

  Next, the contents of the processing of the server 6 shown in FIGS. 1 and 2 will be described. FIG. 3 shows a processing outline of the server 6 as steps S11 to S14.

  In step S11, the location information history 612 is accumulated by repeatedly acquiring the location information of all children and all crime prevention cooperators registered in advance using GPS periodically (for example, every 5 minutes). Here, the location information collection unit 602 periodically acquires the location information of the GPS mobile phone 2 of the child and the security cooperator using the location search service 8 of the mobile phone company, for example, every 5 minutes. Accumulated as history 612 (FIG. 6). At that time, the position information collection unit 602 acquires the GPS mobile phone number of the position search target person from the child personal information table 610 and the security collaborator personal information table 611 (FIGS. 4 and 5). Then, a search request is issued to the location search server 8 of the mobile phone company using the GPS mobile phone number to be searched as a parameter, and the search result is received.

  FIG. 4 is a diagram illustrating an example of the child personal information table 610. In this example, the child personal information table 610 is associated with the telephone number of the GPS mobile phone 2 carried by the child who is registered as a monitoring target, and the child's name, guardian mobile phone number, guardian phone number. And a plurality of pieces of identification information of the guardian mail address. FIG. 5 is a diagram illustrating an example of the personal information table 611 for crime prevention cooperators. In this example, the personal information table 611 for the security collaborator is associated with the telephone number of the GPS mobile phone 2 carried by the security collaborator registered in advance, and the email address, name, age, gender, occupation of the security collaborator. And a plurality of identification information of addresses.

  FIG. 6 is a diagram illustrating an example of the position information history 612. In this example, the position information history 612 includes the search time of the position search server 8, the phone number of the GPS mobile phone 2 of the search target person, the position acquisition time, the latitude and longitude of the GPS mobile phone 2 of the acquired search target person, and the acquired It consists of information on error radius included in latitude and longitude. The error radius information is information returned from the position search server 8 in association with the latitude / longitude information for each search. For example, when the position is acquired without using the GPS (the position within the underground facility) The value differs depending on the search.

  Note that the position search time zone (time zone for performing position search) in step S11 may be performed continuously for 24 hours. For example, when the position search service 8 is provided as a paid service, In order to reduce the usage fee of the search service 8, it may be limited to a time zone (for example, 7:00 to 19:00) in which the child may go out. This position search time zone may be set for each individual.

  In addition, collection of location information of children and crime prevention partners is basically done every day, but on Saturdays and Sundays, since children are often with their families, search is performed to reduce the usage fee of the location search service 8. The day of the week to be performed may be designated. Further, in one day, for example, position information may be collected every 5 minutes during a time period from 7:00 to 19:00.

  In addition, in order to reduce the usage fee of the location search service 8, the location information history acquisition (and analysis) of the security cooperator may be performed about once every one to three months. At this time, the acquisition of position information for each time is basically performed continuously for one week. Further, in one day, for example, the position information is acquired every 5 minutes during a time period from 7:00 to 19:00. In this case, the movement history data (information recorded in the movement history table 613) of the crime prevention cooperator may be continuously used throughout the period until the position-acquired one-week data is next updated.

  Note that the location information collection unit 602 requests the location information history analysis unit 603 to perform analysis processing when it becomes necessary to analyze the location information history of the child or the crime prevention cooperator.

Next, in step S12, the position information history analysis unit 603 performs the following processing.
(A) From the position information history 612 (FIG. 6), the history for the last one week is extracted for each GPS mobile phone 2.
(I) Judge whether the movement is from the part where the data of the same point (same latitude / longitude is the same (the determination criteria for whether it is the same) will be described later) or not, and the movement start time and movement end Find the time.
(Iii) Find the day of the week from the position acquisition time.
(E) The movement speed is obtained from the position information history (position acquisition time, latitude, longitude) from the movement start time to the movement end time. The moving speed is obtained as an average moving speed by dividing the moving distance obtained based on changes in latitude and longitude by the moving time.
(O) From the above, the movement history table 613 (FIG. 7) is created.

  The movement history table 613 shown in FIG. 7 is associated with the telephone number of the GPS mobile phone 2 of the child or the crime prevention cooperator, and shows one continuous movement state from the movement start to the movement end in one pattern (one type or one). Unit), and includes information on the day of the week, the pattern number, the movement start time within the pattern, each time at every fixed time during the movement, the latitude and longitude of each movement end time, and the movement speed at each time. Yes. In addition, two movement history tables 613 are prepared separately for children and for crime prevention cooperators.

  Note that whether the latitude / longitude of (ii) is the same is determined by whether the latitude / longitude of one history is within the latitude ± α / longitude ± β of the other history. For example, α and β are fixedly determined to be within about 100 m, or are determined each time in consideration of the error radius of the position information.

The history analysis operation method has the following two patterns.
(A) The child position information history 612 is analyzed every week, and a new movement history table 613 is created and operated each time. The newly created movement history table 613 continues to be used for one week until the next update.
(A) The child's location information history 612 is analyzed every week, and an unprecedented pattern is added to the movement history table 613 for operation. Whether the pattern is unprecedented or not is determined by regarding the same day of the week as the movement start position and the movement end position and the same movement speed are regarded as the same movement. Considering that the return time of the child fluctuates due to this, if the movement route and the movement speed are the same on the corresponding day of the week, the movement is regarded as the same even if the movement start time is different. Note that whether or not the moving speed is the same is determined in consideration of an error in position information.

  Next, in step S13, the location information collection unit 602 repeatedly acquires the location information of the child's GPS mobile phone 2 periodically (for example, every 5 minutes) using the location search service 8 of the mobile phone company, It accumulates as position information history 612 (for details, refer to step S11). Further, the position information collection unit 602 performs the following processing.

(A) The collected position information of the child is transferred to the difference detection unit 604 from the normal movement, and the process is requested.
(B) The collected position information of the child is transferred to the dangerous area approach prediction unit 605 and requested to be processed.
(C) The collected location information of the child is transferred to the dangerous area entry detection unit 606 and requested for processing.

  There are the following two methods for determining that the movement of the child by the difference detection unit 604 in step S13 (a) is significantly different from the normal movement.

  (I) The first method is a method of determining whether or not one of the following (i1) to (i4) is satisfied for each of a plurality of movement patterns for the corresponding day of the week in the movement history table 613 of FIG. If the movement route matches on the day of the week, the determination method is OK even if the movement start time is different. When any of the conditions (i1) to (i4) is satisfied, it is determined that a difference from the normal movement has occurred.

(I1) The movement start location does not match the movement start location of any movement pattern on the corresponding day of the week. This condition corresponds to, for example, a case where movement is started from a place visited for the first time.
(I2) Although the movement start location coincides with the movement start location of a certain movement pattern of the corresponding day of the week, the acquired current position does not match any intermediate position in the corresponding movement pattern, and is significantly different from any position (for example, , There is a shift of more than 2km). This condition corresponds to, for example, when taking a detour.
(I3) The movement end location does not match the movement end location of any movement pattern on the corresponding day of the week. This condition corresponds to, for example, the case where the movement is finished at the place where the user visited for the first time.
(I4) The movement start location, midway location, or movement end location matches the location of a certain movement pattern on the day of the week, but the movement speed is significantly faster than the value of the movement history table (for example, the movement speed of the movement history table 613) 10 times faster than) or significantly slower (eg 0 m / s). This condition corresponds to, for example, when the user leaves the house and is put in a car or the mobile phone is thrown away.

  (II) The second method is a method of determining whether or not the place has been visited or passed through on the day of the week. In this method, determination is made based on whether or not the acquired current position does not match the latitude and longitude of any time on the day of the week and is significantly different from any position.

  In the above two methods (I) and (II), whether the acquired current position matches the latitude / longitude in the movement history table 613 depends on the error radius centered on the latitude / longitude of the acquired current position. This determination is made based on whether the latitude / longitude in the movement history table 613 is included in the circle.

  Further, when the difference detection unit 604 from the normal movement determines that the movement of the child is significantly different from the normal movement, the emergency information notification method to the guardian is performed as follows. When it is determined that the movement of the child is significantly different from the normal movement, the difference detection unit 604 requests the mail transmission unit 607 to notify the guardian that the movement is significantly different from the normal movement. To do. A URL for referring to a map showing the current position of the child is embedded in the mail. The guardian can receive the mail with the mobile phone 3 or the communication terminal 4 and access the embedded URL with a browser or the like, thereby obtaining the map information indicating the current position of the child from the map service 7 (hereinafter referred to as the following). The same.) Alternatively, a map showing the current position of the child may be acquired by using the map service 7 in the server 6 and sent by attaching to a mail.

  In addition, a URL for requesting assistance to a security cooperator is embedded in the e-mail. The URL for requesting this support includes the telephone number of the child's GPS mobile phone 2 and the current latitude / longitude information, and the rush request processing unit 609 in the server 6 responds to access from the guardian. List information indicating a list of crime prevention cooperators around the current location of the child is created and transmitted and displayed on the parent's mobile phone 3 and communication terminal 4 (the same applies hereinafter).

  Not only mail but also notification by 3PCC (that is, for example, a process of making a call connection between a parent and a child terminal using 3PCC) may be performed.

  Editing and transmission of these mails are performed by the mail transmission unit 607 in response to a request from the difference detection unit 604 for normal movement. The mail transmission unit 607 refers to the child personal information table 610, acquires the guardian mail address, and transmits the mail (the same applies to the following mail transmission).

  On the other hand, the process by the dangerous area approach prediction unit 605 in (b) of step S13 is performed as follows. The dangerous area approach prediction unit 605 checks the past location information history 612 if the acquired current location is within a certain range from the dangerous area, and notifies the guardian by e-mail if it is found that the distance from the dangerous area is short. . Here, whether or not it is within a certain range is determined by checking whether or not the current location is within latitude ± a and longitude ± b of the dangerous area center point. Or whether the straight line distance between the two points calculated from the latitude and longitude of the current location and the central point of the dangerous area or the distance of the shortest route that can be passed between the two points of the current location and the central point of the dangerous area is shorter than a certain distance Judge by no. The distance of the shortest route that can be passed between two points is calculated using the map service 7. Further, the latitude / longitude of the dangerous area center point is acquired from the dangerous area definition table 614 (FIG. 8).

  FIG. 8 is a diagram illustrating an example of the dangerous area definition table 614. In this example, the dangerous area definition table 614 indicates the type of dangerous area (construction site, frequent crime zone, park, mountain, river, etc.) and the address of the dangerous area in association with the latitude and longitude information of the dangerous area. It is configured by holding character information.

  Further, the above-described values a and b used for determining whether or not they are within a certain range vary depending on the size of the danger area. For example, when the danger area is a narrow area having a radius of about 10 m, a and b are determined so as to be within (300 m + positioning error) from the center point of the danger area. When the danger area is a relatively large area such as a park, the determination is made based on a wider range.

  The method for notifying the guardian of emergency information when the dangerous area approach prediction unit 605 determines that the distance from the dangerous area is short is as follows. The dangerous area approach prediction unit 605 notifies the guardian by e-mail that the child is heading to the dangerous area. The address of the dangerous area and the dangerous area type (for example, a construction site) are acquired from the dangerous area definition table 614 and included in the mail text. In addition, a URL for referring to a map showing the current position and dangerous area of the child is embedded in the mail. Alternatively, a map showing the current position of the child may be acquired using the map service 7 and sent as an email attachment.

  In addition, a URL for requesting assistance to a security cooperator is embedded in the e-mail. Not only mail but also notification by 3PCC (that is, for example, a process of making a call connection between a parent and a child terminal using 3PCC) may be performed. Mail editing and transmission are performed by the mail transmission unit 607 in response to a request from the dangerous area approach prediction unit 605.

  On the other hand, the process by the dangerous area approach detection unit 606 in step S13 (c) is performed as follows. If the acquired current location is within the dangerous area, the dangerous area approach detection unit 606 notifies the guardian by 3PCC and mail. In this example, unlike the above (a) and (b), notification by 3PCC is essential. At this time, if the current location is within the latitude ± c and longitude ± d of the central point of the dangerous area, it is determined that the user has entered the dangerous area. Or, (x) the distance between two points obtained from the latitude and longitude of the current location and the center of the dangerous area, or (y) the distance of the shortest route that can be passed between the two points of the current location and the center of the dangerous area. Judgment is made based on whether the distance is shorter than a certain distance.

  The distance of the shortest route that can be passed between two points is calculated using the map service 7. Further, the latitude / longitude of the dangerous area center point is acquired from the dangerous area definition table 614 (FIG. 8).

  Further, the values c and d used for determining whether or not the current location is in the danger area differ depending on the size of the danger area. For example, when the danger area is a narrow area having a radius of about 10 m, c and d are determined so as to be within (10 m + positioning error) from the center point of the danger area. Note that the values a and b used for determining whether or not the distance from the dangerous area is within a certain range are parameters used to detect the approach to the dangerous area, and c and d are the dangerous areas. The parameter used to detect the entry is different. Usually, the relationship is a> c, b> d.

  Further, the emergency information is notified to the guardian when the current area is determined to be in the dangerous area by the dangerous area approach detection unit 606 as follows. The 3PCC unit 608 obtains a guardian's mobile phone number from the child personal information table 610 and connects the child's and the guardian's mobile phones 2 and 3 by 3PCC to enable a call. In addition, parents will be notified by email that the child has entered the danger area. The address of the dangerous area and the dangerous area type (for example, a construction site) are acquired from the dangerous area definition table 614 and included in the mail text. In addition, a URL for referring to a map showing the current position and dangerous area of the child is embedded in the mail. Alternatively, a map showing the current position of the child may be acquired using the map service 7 and sent as an email attachment. A URL for requesting assistance to security cooperators is also embedded in the email. The mail transmission unit 607 performs editing and transmission of the mail in response to a request from the dangerous area approach detection unit 606.

  In addition, after the notification to the guardian is completed once in step S13, when the alarm (abnormal state) of the same child is detected, that is, when the notification condition is satisfied in the determinations (a) to (c) However, if a certain period of time (for example, 30 minutes) has not elapsed, the parents are not notified again. By doing in this way, it is possible to prevent the notification of the alarm due to the same event many times (notification of emergency information).

  Next, in step S14, a process for responding to the rushing request from the guardian who has been notified by e-mail or 3PCC is performed.

  Note that the guardian does not always make a rushing request even when notified. That is, when the guardian is notified by mail from the server 6, he calls the child's GPS mobile phone 2 and checks the state of the child. If it is confirmed that there is no particular problem with the telephone connection, the process ends there. If you are in danger or you are unable to make a call, you will be asked to cooperate with a security cooperator.

  Further, when the guardian is notified by the 3PCC from the server 6, the guardian makes a call with the child at the 3PCC, and when it is confirmed that there is no particular problem, the process ends there. If you are in danger or you are unable to make a call, you will be asked to cooperate with a security cooperator.

  The procedure when a guardian makes a rush request is as follows. In steps S13 (a), (b), and (c), the URL for requesting assistance to the security cooperator is embedded in the email notified to the guardian. Click the URL. It is possible to request assistance. In the present embodiment, the server 6 can extract the parameters by including the GPS mobile phone number for identifying the child and the location information of the child as parameters in the URL embedded in the mail. Yes.

  The processing procedure of the server 6 when receiving a rush request from a guardian is as follows (see FIG. 10). In FIG. 10, steps S <b> 21 and S <b> 27 indicate operations by the guardian, and steps S <b> 22 to S <b> 26 indicate processing by the server 6.

  First, the guardian clicks a URL for requesting support in the mail (step S21). In response to the access from the guardian, the rush request processing unit 609 performs the following processing.

  In step S22, the rushing request from the guardian is received, and the GPS mobile phone number for identifying the child and the location information of the child are extracted from the URL.

  In step S23, a security cooperator who may be near the child is picked up in the movement history table 613 for the security cooperator based on information on the day of the week, time, latitude, and longitude. As described above, the movement history table 613 is divided for children and crime prevention cooperators. Also, pick up crime prevention cooperators who fall within the latitude ± e and longitude ± f of the current location of the child. e and f are determined to be about 500 m or less, for example. The latest position information of the security cooperators picked up here may be collected using the position search service 8 to further narrow down the target persons.

  Next, in step S24, the map service 7 is used to obtain the shortest path distance between the child and the security cooperator.

  Next, in step S25, information on the security cooperator is obtained from the personal information table 611 for the security cooperator, sorted and edited in ascending order of distance as shown in FIG. 9, and the guardian terminal (cell phone 3 or communication terminal 4). ) To provide such information. The name of the child is acquired from the child personal information table 610.

  FIG. 9 shows an example of information (screen display 9) of the security cooperator provided to the guardian's terminal (mobile phone 3 or communication terminal 4). In this example, information of two security cooperators near the child “Makuhari Ichiro” can be displayed. The information of the security cooperator includes identification information such as the name, age, sex, occupation, distance from the child, and the telephone number of the GPS mobile phone 2 of the security cooperator.

  Next, in step S26, a rushing request mail is transmitted to all of the picked-up crime prevention cooperators (*). The mail transmission unit 607 transmits the mail in response to a request from the rushing request processing unit 609. The rushing request email includes the child's name, the child's current location address (obtained using the map service 7), the distance from the security cooperator to the child, the child's guardian's mobile phone number, telephone number, and email address It is. In addition, a map image showing the location of the child and the crime prevention collaborator and the route from the crime prevention collaborator to the child is attached to the mail.

  * In this embodiment, priority is given to urgency at this point, and an e-mail is sent to all the crime prevention cooperators who have been picked up. Although there is no guarantee that you will be able to rush even if you send an e-mail, I do this because I think that if you send an e-mail, someone may rush. In addition, there is a possibility that mail will be delayed and not delivered immediately. You can skip this email sending step and go straight to step S27, but in the case of a parent's way of making a call, even if you call a collaborator who wants to rush, that person will not be rushed immediately There is a possibility that it may take time to find people who can rush.

  Next, in step S27, the guardian looks at the information of the security cooperator provided from the server 6, calls the cooperator who wants to rush, and confirms whether or not it can be rushed.

The following modifications can be made to the above-described embodiment.
(1) When there is no crime prevention collaborator in the default area (for example, within 500 m), an interface (for example, within 750 m, within 1 km, etc.) that expands the search area may be provided.
(2) In the present embodiment, the position search cycle is fixed uniformly (for example, every 5 minutes), but the search cycle and the number of searches may be changed for each individual.
(3) In the present embodiment, an example is shown in which the location information history analysis is limited to one week of data. However, the analysis target period may be one month or one year, or in the spring, summer, autumn, and winter periods. It may be divided. In the case of children, they may be divided into long vacation periods such as spring break, summer break, winter break, and other periods. Further, the collection and analysis method of holiday history such as holidays may be changed.
(4) In this embodiment, when the entry to the dangerous area is detected, the call between the child and the guard is connected by 3PCC, but the guardian calls the child directly without using 3PCC. May be.
(5) In the present embodiment, an example in which GPS is used to detect that the vehicle has entered the danger area has been shown, but wireless tag (RFID) technology, infrared, Bluetooth (registered trademark), wireless LAN (Local Area Network), UWB ( A method of detecting that the vehicle has entered the danger area using a short-range wireless communication technology such as Ultra Wide Band (ZideBee (registered trademark)) may be used.

  As described above, according to the present embodiment or a modification thereof, a plurality of movement patterns are accumulated by analyzing the movement history of a monitoring target person such as a child classified by day of the week. Since it is determined whether or not to notify emergency information (alarm) based on the pattern, abnormal conditions in children who have different movement patterns for each day of the week without performing complicated movement pattern registration / change operations It can be determined automatically.

  In addition, when notifying parents, the parents can refer to information such as gender and age of crime prevention cooperators near the child, so it is expected that the child will enter or enter the danger area. In response to the situation (for example, according to the distance from the child, the sex / age of the collaborator, etc.), it is possible to extract and notify a specific crime prevention collaborator around the child. In other words, a guardian can ask a specific security cooperator who is near the child to rush to check the situation of the child.

  Therefore, according to the embodiment of the present invention, the convenience and practicality of a communication system, which is a system that supports monitoring of a monitoring target person such as a child using a communication terminal such as a mobile phone, is improved as compared with the prior art. be able to.
