Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a conceptual diagram for explaining an outline of a dangerous area approach detection method according to an embodiment of the present invention. In the figure, the dangerous area entry detection device 1 is registered as a dangerous area in the dangerous area entry detection device 1 together with the degree of danger by the occurrence of some trigger (for example, an incident or accident, movement from a designated place). (SS1). Then, triggered by having been registered as a dangerous area, or at a predetermined time interval, the dangerous area approach detection device 1 requests the current position information of the monitoring subject registered in advance in the position information server 2. To collect (SS2).

  The person to be monitored possesses mobile phones 3-1, 3-2,..., 3-n equipped with a GPS receiver, an RFID tag, and the like. The cellular phones 3-1 to 3-n acquire position information indicating the current position by the GPS and RFID readers (not shown) arranged in various places. In GPS receivers, accurate latitude and longitude cannot be determined in places where radio wave conditions are poor. Therefore, in places where accurate information collection is difficult, such as RFID readers that can grasp position information at radio wave distances of several tens of meters. Use a means by which accurate location information can be collected. Note that the cellular phones 3-1 to 3-n have (1) only the RFID tag, (2) only the GPS receiver function, and (3) both the RFID tag and GPS receiver functions. There are cases where it is prepared. Further, the person to be monitored may hold a mobile terminal such as an IC card or a sensor device that has either or both of the functions of the RFID tag and the GPS receiver instead of the mobile phone.

  When it is determined from the collected location information of the monitoring target person that the monitoring target person is present in the registered danger area, the dangerous area approach detection device 1 is a communication means that guarantees real-time performance (for example, The monitor and the monitoring target are connected by a telephone or the like in a state where bidirectional communication is possible (SS3). On the other hand, if it is out of the danger area, information including map information is transmitted to the monitor by non-real-time communication means (for example, messenger or mail).

  In the present invention, the danger areas are classified and classified into three types according to the degree of danger (or danger) (four types if a non-dangerous area is included). The dangerous area approach detection device 1 enables different actions (selection of communication means) according to the risk level. For example, in the case of the most dangerous area, use communication means that guarantees real-time characteristics (for example, a telephone), and in the case of a dangerous area but a low risk level (assuming the school route of the person being monitored) ) Can use communication means (for example, messenger, mail, etc.) that does not guarantee real-time performance.

  For example, if the monitored person (child) is in the school (non-dangerous area) or if the monitored person (child) is far from the accident site (outside the dangerous area) Affix the information and contact the guardian who is the supervisor. In addition, when the person to be monitored (child) is near the accident occurrence site (in the danger area), the telephone of the guardian (landline or mobile phone) who is the supervisor is directly connected to the child's mobile phone. Setting to connect is also possible.

  Next, FIG. 2 is a conceptual diagram showing the relationship between the danger area, the monitor, and the monitoring target person. In FIG. 2, the monitoring person 10 and the monitoring target person 11 have a one-to-n relationship, and the monitoring person 10 and the notification destination designation information 12 have a one-to-n relationship. Further, the supervisor 10 and the warning area 13 have a one-to-n relationship, and the supervisor 10 can set a plurality of risk areas 13 for a plurality of monitoring subjects 11. Further, the registrant (local government, police, fire department, etc.) 14 and the monitoring subject 11 have an n-to-n relationship, and the registrant 14 and the contact designation information 15 have a one-to-n relationship. The registrant 14 can set a plurality of danger areas 13 for all the monitoring subjects 11. In the present embodiment, when a plurality of report destination designation information 12 set by the monitor 10 can be notified of warning area entry corresponding to the degree of danger, and when the contact with the monitor 10 is not established, etc. A warning area entry is notified to the default contact address designation information 15.

  FIG. 3 (a) is a conceptual diagram showing an example of registration of a monitor and a monitoring target person. FIG. 3 (b) shows the risk area registered by the monitor and the risk area registered by the registrant. It is a conceptual diagram which shows the example of registration. In FIG. 3A, the monitor “A00001” registers two monitor subjects “A10001” and “A10002”, and the monitor “A00002” registers one monitor target “A20001”. The monitoring person “A00003” indicates a state where one monitoring person “A30001” is registered. Further, as shown in FIG. 3B, the monitor “A00001” has registered “■ intersection” and “▲ convenience store (hereinafter referred to as convenience store)” as the danger area, and the monitor “A00002” Unregistered, the supervisor “A00003” has registered “○ Near High Speed” and “▲ Park”. In addition, the registrant registers “× park”, “△ intersection”, “■ building”, “▲ intersection” as common danger areas for the observers “A00001”, “A00002”, “A00003”. is doing.

  Therefore, in addition to “■ intersection” and “▲ convenience store” registered by the supervisor “A00001”, the dangerous area “× park”, “△ intersection”, “■ building”, “▲” At the four intersections, you will receive notification of entering the danger area for the person you are monitoring. In addition, the supervisor “A00002” does not register the dangerous area by himself, but the registered dangerous area “× Park”, “△ Intersection”, “■ Building”, “▲ Intersection” is 4 places. The notification of entering the dangerous area for the monitoring target person registered by himself / herself is received. In addition to the “O highway vicinity” and “▲ park” registered by the supervisor “A00003”, the dangerous area “× park”, “△ intersection”, “■ building”, “ You will receive notification of entering the dangerous area for the person you have registered at the four intersections.

  Next, FIGS. 4A and 4B are conceptual diagrams showing the relationship between the dangerous area registration and the monitoring target person. In FIG. 4A, the dangerous area registered by the supervisor 10-1 is A1, the dangerous area registered by the supervisor 10-2 is A2, and the dangerous area registered by the registrant 14 is A3 (solid line). The danger area registered by the supervisor and the danger area registered by the registrant 14 may partially overlap. That is, the risk area registered by the registrant targets all the monitoring target persons, and the risk area registered by the monitor targets the monitoring target person associated with the monitor.

  FIG. 4 (b) shows an example of the dangerous area registration status for the four monitoring subjects A to D. FIG. That is, the dangerous area set by the supervisor 10-1 (A) is the monitoring subject A and C, and the dangerous area set by the supervisor 10-2 (B) is the supervisor B, D. Is the monitoring target. And the danger area set by the registrant has all the monitoring subjects A to D as the monitoring targets.

  In FIG. 4A, the monitoring person 10-1 and the monitoring target person are notified to the monitoring person 10-1 when the monitoring target person enters the dangerous area A1 and the dangerous area A3 (dotted line). . In addition, the monitoring person 10-2 and the monitoring target person are notified to the monitoring person 10-1 when the monitoring target person enters the dangerous area A2 and the dangerous area A3 (dotted line).

  In addition, the registrant and the monitor may be the same, but in many cases, only the registrant who performs registration for all the monitoring targets and the specific monitoring target (including a plurality) It can be roughly divided into the observers. Even when the monitoring target person enters the danger area set by the registrant, the monitoring person may not be notified. When the monitoring subject enters the danger area, the registrant 14 or the security company 16 is notified as an emergency evacuation destination when the monitoring person cannot be contacted (dotted line).

  Next, FIG. 5 is a conceptual diagram showing an example of correspondence between the danger level of a danger area, notification means, and communication destination information communicated by the notification means. In the figure, in this embodiment, four risk levels A, B, C, and-("-" is a non-dangerous area) are provided. The action for notifying the warning differs depending on the communication means set according to the degree of risk. In the illustrated example, at the risk level A, a telephone is set as a real-time communication for directly connecting a monitor and a monitoring target, and a telephone number of the communication destination is set. In the risk level B, a telephone is set as a real-time communication for directly connecting a supervisor and a guidance device (synthesized voice or the like), and a telephone number of the communication destination is set. At risk level C, mail is set as non-real-time communication for the supervisor, and the mail address of the communication destination is set. Even in the case of the risk level C, “−”, mail may be set as the communication means, and the mail address of the communication destination may be set. Also, the communication means corresponding to the degree of danger can be selected by the supervisor, and address information of the communication destination suitable for the communication means is set.

  If the communication destination cannot be contacted, as described above, a predetermined contact (default contact) is contacted. In addition, since there is a possibility that the monitoring target person may take collective action, the SMTP server 8 should be selected in round robin so that it will not be treated as spam by e-mail, and the time will be shifted so that it will not be treated as a malicious call by simultaneous calling by telephone. Take measures such as contacting them. The illustrated combination is an example, and it is possible for a monitor to freely associate an action and a notification means according to the degree of risk.

  Next, FIG. 6 is a conceptual diagram for explaining the change of the risk level for the same danger area. There is a possibility that the designation of the dangerous area is duplicated between the registrant and the supervisor. For this reason, between the registrant and the supervisor, there is a possibility that different risk levels may be set for the same risk area, so it is necessary to set a limit for changing the risk level. Basically, the risk cannot be lowered, but it is allowed to be raised. In other words, the risk level A, B, C set by the registrant can be changed by the supervisor (the risk level A can only be changed because it can only be changed, the risk level B, C can be changed to the risk level A or risk level B. Changeable). On the other hand, the registrant cannot change any of the risk levels A, B, and C set by the supervisor.

  Next, FIG. 7 is a block diagram showing a schematic configuration of the dangerous area approach detection system according to the present embodiment. In the figure, the dangerous area approach detection device 1 registers the dangerous area and the degree of danger, acquires the position information of the monitoring target, detects the monitoring target person entering the dangerous area, and the monitoring target enters the dangerous area. Control the entire system, such as notifying the observer at the time. The location information search server 2 is a mobile phone 3 equipped with a GPS (which may be another portable communication terminal) carried by the monitoring subject in response to a location information search request from the danger area approach detection device 1. Are collected and supplied to the dangerous area approach detection device 1. The tag reader 4 is installed in a predetermined place (a school, a school road, a children's park, a newly registered danger area, etc.), reads the tag radio wave of the mobile phone 3 that has approached, and notifies the danger area entry detection device 1.

  The map server 5 supplies the corresponding map information to the dangerous area approach detection device 1 from the map creation request (latitude / longitude and position information) from the danger area approach detection device 1. The presence server 6 checks the communication status of the supervisor's telephone, which is registered in advance, in response to the communication status request from the dangerous area entry detection device 1, and notifies the danger area entry detection device 1 of the availability of communication. . The voice communication system 7 is a telephone exchange or a telephone server, and directly connects the telephone 20 of the supervisor and the mobile phone 3 of the person to be monitored by voice communication. The SMTP server 8 transmits mail when notifying the supervisor by mail.

Details of the various tables will be described later. The protocol control unit 1-5 handles various protocols (HTTP / SIP / SIMPLE etc.) and controls communication with the registrant's terminal or the monitor's terminal. The location information control unit 1-6 makes a search request to the location information search server 2 in accordance with information (location search number of the monitoring subject, authentication information) required for the location search received from the danger area control unit 1-3. And the latitude / longitude are received from the position information search server 2 as a search result. When the communication means selected according to the dangerous area is mail, the map information control unit 1-7 is supplied with a latitude / longitude (latitude / longitude) to create a map URL supplied from the dangerous area control unit 1-3. The monitoring target person's position information) is supplied to the map server 5 to request map creation, and the URL (the URL of the map around the current position of the monitoring target person) is received from the map server.

  The mail control unit 1-8 creates a mail from the address and position information supplied from the dangerous area control unit 1-3, and transmits the mail to the SMTP server 8. The SMTP server 8 transmits an email in which information such as a map URL is described to the address. The voice communication control unit 1-9, according to the address (telephone number) supplied from the dangerous area control unit 1-3, in order to enable voice communication between the monitoring target person and the supervisor's telephone, A connection is requested to the communication system 7. In addition, the voice communication control unit 1-9 confirms the communication state before the voice communication is executed by the voice communication system 7, and performs telephone number selection.

Next, the operation of the above-described embodiment will be described.
FIG. 17 is a flowchart for explaining the operation at the time of new registration of a dangerous area by the dangerous area approach detection system of the present embodiment. This flowchart is executed when a dangerous area is newly registered, acquires position information of the monitoring target person, and sends warning information to the monitoring person by communication means according to the risk level of the newly registered dangerous area. It comes to notify.

  For example, when an incident / accident occurs, a registrant (police, fire department, etc.) accesses the dangerous area notification device 1 from the registrant's terminal and registers the location where the incident / accident occurred as a dangerous area. Alternatively, the dangerous area notification device 1 is accessed from the terminal of the supervisor, and a new dangerous area is registered. In the dangerous area notification device 1, when the input control unit 1-1 detects the registration of the dangerous area (step Sa1), the dangerous area control unit 1-3 displays the dangerous area information input by the input control unit 1-1. Register in the database 1-4 (step Sa2).

  Next, the position information control unit 1-6 acquires the position information of the person to be monitored from the position information search server 2 (step Sa3), and the dangerous area control unit 1-3 performs step Sa2 based on the position information. It is determined whether or not it is within the registered danger area (step Sa4). If it is determined that the person to be monitored is in the dangerous area registered in step Sa2, the dangerous area control unit 1-3 uses the general user contact information table 1-4-5 in the database 1-4. The communication means corresponding to the danger level of the registered danger area is selected (step Sa5). On the other hand, when it is determined that the person to be monitored is outside the dangerous area registered in step Sa2, the communication means corresponding to the non-hazardous area is selected (step Sa6).

  Next, the dangerous area control unit 1-3 acquires a contact address corresponding to the communication means selected from the general user contact information table 1-4-5 of the database 1-4 (step Sa7), and contacts It is determined whether there is an address (step Sa8). When the general user contact information table 1-4-4-5 has a contact address, the user information management unit 1-10 sends presence information (showing the call state of the contact address) from the presence server 6 ( Whether or not communication is possible (step Sa10), and it is determined whether or not communication is possible (step Sa11). If communication is not possible, such as when the power of the supervisor's mobile phone is not turned on, the process returns to step Sa7 to acquire the next contact address and determine whether communication is possible.

  On the other hand, when the acquired contact address is communicable, communication processing for notifying the status of the person to be monitored is executed for the contact address according to the communication means selected according to the degree of risk. (Step Sa12). For example, when the registered danger area has a high risk level, such as a risk level A, the voice communication system 7 executes communication processing for directly connecting the supervisor's telephone and the monitoring subject's mobile phone. . As a result, when a monitoring target person enters the registered danger area, the monitoring person and the monitoring target person can talk directly by voice call at the time of registration (or immediately after registration). become.

  Further, for example, when the person to be monitored is outside the registered danger area or when the danger level of the registered danger area is relatively low, the mail control unit 1-8 causes the danger area control unit 1-3. From the contact address and location information supplied from the mail, a mail in which the URL of the map information is described is created and transmitted by the SMTP server 8. As a result, when the monitoring target person is outside the registered danger area, or when the danger level of the registered danger area is relatively low, the monitoring person can know the location of the monitoring target person by e-mail. It becomes like this.

  Next, the dangerous area notification device 1 determines whether or not the communication is normally completed (step Sa13). If the communication is not normally terminated, the process returns to step Sa4 to acquire the next contact address. Then, the above process is repeated.

  If it is determined in step Sa8 that there is no contact address, the default address table 1-4-6 is referred to, and a contact address (default address) corresponding to the danger level of the registered dangerous area is obtained. Obtain (step Sa9). In the case of the default address, there is no need to acquire presence information because it is a contact address (telephone number or the like) of a police, a fire department, a security company or the like that can always make a call. Thereafter, the steps Sa12 and Sa13 described above are executed to contact the registrant of the default address. Therefore, even when the supervisor cannot be contacted, it is always possible to contact the registrant (police, fire department, security company, etc.).

  Further, when the communication is normally completed, it is determined whether or not the process is completed for all the monitoring target persons (step Sa14), and when the communication is not completed for all the monitoring target persons, the process goes to step Sa3. Returning, the position information of the next person to be monitored is acquired, and the processing after step Sa4 described above is executed. And when the process of the said flow is completed with respect to all the monitoring object persons, the said process will be complete | finished.

  Next, FIG. 18 is a flowchart for explaining the operation at the time of regular processing by the dangerous area approach detection system of this embodiment. The flowchart is executed each time a predetermined time elapses (at a predetermined interval), acquires position information of the monitoring target person, and, if present in the danger area, corresponds to the danger level of the danger area Warning information is notified to the supervisor by the communication means.

  First, in the dangerous area notification device 1, the position information control unit 1-6 acquires the position information of the monitoring target person from the position information search server 2 (step Sb1), and the dangerous area control unit 1-3 receives the database 1- 4, whether or not the person to be monitored exists in the danger area is determined based on the position information with reference to the risk information table 1-4-2 for the management user 4 and the general user contact information table 1-4-5. (Step Sb2). When it is determined that the person to be monitored is in the dangerous area, the dangerous area control unit 1-3 refers to the general user contact information table 1-4-5 in the database 1-4 and performs monitoring. The communication means corresponding to the danger level of the danger area where the person is present is selected (step Sb3).

  Next, the dangerous area control unit 1-3 acquires a contact address corresponding to the communication means selected from the general user contact information table 1-4-5 of the database 1-4 (step Sb4), and contacts It is determined whether there is an address (step Sb5). When the general user contact information table 1-4-4-5 has a contact address, the user information management unit 1-10 sends presence information (showing the call state of the contact address) from the presence server 6 ( Whether or not a call is possible is acquired (step Sb7), and it is determined whether or not communication is possible (step Sb8). If communication is not possible, such as when the power of the supervisor's mobile phone is not turned on, the process returns to step Sb4 to acquire the next contact address and determine whether communication is possible.

  On the other hand, when the acquired contact address is communicable, communication processing for notifying the status of the person to be monitored is executed for the contact address according to the communication means selected according to the degree of risk. (Step Sb9). That is, as in the case of the registration described above, for example, when the monitoring target person is present in a high-risk risk area such as the risk level A, the voice communication system 7 causes the monitoring person's telephone and the monitoring target person's mobile phone to be Connect directly to the phone. As a result, when the monitoring target person has entered a dangerous area with a high degree of risk, the monitoring person and the monitoring target person can make a voice call directly. Further, for example, when the monitoring target person is in a dangerous area with a slightly low risk level, the map information is obtained from the contact address and position information supplied from the dangerous area control unit 1-3 by the mail control unit 1-8. Is created and sent by the SMTP server 8. Thereby, when the monitoring target person is in a dangerous area with a low risk level, the monitoring person can know the location of the monitoring target person by mail.

  Next, the dangerous area notification device 1 determines whether or not the communication is normally completed (step Sb10). If the communication is not normally completed, the process returns to step Sb4 to obtain the next contact address. Then, the above process is repeated.

  When it is determined in step Sb5 that there is no contact address, the default address table 1-4-4-6 is referred to, and a contact address (default address) corresponding to the danger level of the registered dangerous area is obtained. Obtain (step Sb6). In the case of the default address, there is no need to acquire presence information because it is a contact address (telephone number or the like) of a police, a fire department, a security company or the like that can always make a call. Thereafter, the above-described steps Sb9 and Sb10 are executed to contact the registrant of the default address. Therefore, even when the supervisor cannot be contacted, it is always possible to contact the registrant (police, fire department, security company, etc.).

  If the communication is normally terminated, it is determined whether or not a predetermined time has elapsed (step Sb11). If the predetermined time has elapsed, it is determined whether or not an end request has been received (step Sb12). If the request has not been received, the process returns to step Sb1 to acquire the position information of the next person to be monitored, and the processes after step Sb2 described above are executed. The termination request is for forcibly terminating the process for the monitoring target person when a monitoring time (for example, until 3 pm, etc.) is set.

  If it is determined that the person to be monitored is outside the danger area, the process proceeds directly to step Sb11. If a termination request has not been received after a predetermined time has elapsed, the process returns to step Sb1, and the next step The position information of the person to be monitored is acquired, and the processing after step Sb2 described above is executed. Therefore, when the monitoring target person is outside the danger area, no warning information is notified to the monitoring person.

  If an end request has been received, it is determined whether or not the process has been completed for all the monitoring subjects (step Sb13), and if it has not been completed for all the monitoring subjects, the process returns to step Sb1. Then, the position information of the next person to be monitored is acquired, and the processing after step Sb2 described above is executed. And when the process of the said flow is completed with respect to all the monitoring object persons, the said process will be complete | finished.

Next, FIG. 19 is a sequence diagram for explaining an operation at the time of new registration of a dangerous area (using GPS) by the dangerous area approach detection system of the present embodiment.
As described above, for example, when an incident or accident occurs, the location where the incident or accident occurred is registered as a dangerous area from the terminal of the registrant (police, fire department, etc.) or the terminal of the supervisor Assume that a new dangerous area is to be registered. When a terminal of a registrant or a supervisor (hereinafter referred to as a user terminal) accesses the dangerous area notification device 1, first, the protocol control unit 1-5 first receives a user ID received from the terminal, a location name to be registered, and location information. (Latitude, longitude) and risk are supplied to the input control unit 1-1 (step SA1). Since it is generally difficult for the user to input latitude and longitude as position information indicating the position of the dangerous area, an application that presents the latitude and longitude to the user from the place name is prepared.

  The input control unit 1-1 supplies the user ID to the user information management unit 1-10 (step SA2). The user information management unit 1-10 refers to the user information table 1-4-3 of the database 1-4, acquires the role ID corresponding to the user ID, and returns it to the input control unit 1-1 (steps SA3 to SA5). ). If there is no role ID corresponding to the user ID, access is canceled.

  Next, when the role ID is returned, the input control unit 1-1 supplies the user ID, the place name, the position information (latitude, longitude), the degree of danger, and the role ID to the danger area control unit 1-3 ( Step SA6). The dangerous area control unit 1-3 registers the user ID, the place name, the position information, and the risk level in the database 1-4 (step SA7). The database 1-4 supplies the registration result (OK / NG) to the output control unit 1-2 (step SA8). The output control unit 1-2 presents the registration result to the user terminal.

  Next, the dangerous area control unit 1-3 requests user information from the user information management unit 1-10 (step SA9), and acquires the user ID, location search number, and authentication information of the user (step SA9). SA10). Next, the dangerous area control unit 1-3 supplies the position search number and the authentication information to the position information control unit 1-6, and requests a position information search (step SA11). The position information control unit 1-6 accesses the position information search server 2, acquires the position information of the corresponding monitoring target person from the position search number and the authentication information, and supplies it to the dangerous area control unit 1-3 ( Step SA12). The dangerous area control unit 1-3 refers to the database 1-4 with the user ID (step SA13), acquires the position information of the dangerous area corresponding to the user ID (step SA14), and monitors and monitors the position information of the dangerous area. The position information of the target person is collated (step SA15), the danger level of the dangerous area where the monitoring target person exists is specified, and the communication means corresponding to the risk level is selected.

  Next, when it is determined by the above collation that the monitoring target person is in a dangerous area with a relatively low degree of risk or a non-dangerous area, the dangerous area control unit 1-3 determines the position information of the monitoring target person. Is supplied to the map information control unit 1-7, and the URL of the map information is requested (step SA16). The map information control unit 1-7 accesses the map server 5, acquires the URL of the corresponding map from the position information of the monitoring subject, and supplies it to the dangerous area control unit 1-3 (step SA17).

  Next, the dangerous area control unit 1-3 supplies the user ID to the user information management unit 1-10 (SA18), and according to the collation result, the risk level of the dangerous area where the monitoring target person exists and the user of the monitoring person The contact address registered in association with the ID is acquired (step SA19). If it is determined that the person to be monitored is in a dangerous area with a relatively low degree of risk or a non-dangerous area, the dangerous area control unit 1-3 determines the contact address, the place name, and the URL of the map. Is supplied to the mail control unit 1-8 (step SA20). The mail control unit 1-8 creates a mail from the contact address, the place name, and the URL of the map, and transmits the mail from the SMPT server 8 to the monitor.

  On the other hand, if it is determined that the person to be monitored is in a dangerous area with a relatively high degree of risk according to the collation result, the dangerous area control unit 1-3 uses the contact address as the voice communication control unit 1-9. (Step SA21). The voice communication control unit 1-9 directly connects the supervisor's telephone and the monitoring subject's mobile phone by the voice communication system 7 in accordance with the contact address. The above-described processing surrounded by dotted lines from steps SA9 to SA21 is repeated for all users.

Next, FIG. 20 is a sequence diagram for explaining an operation at the time of new registration of a dangerous area (use of a tag) by the dangerous area approach detection system of the present embodiment.
As described above, for example, when an incident or accident occurs, the location where the incident or accident occurred is registered as a dangerous area from the user terminal of the registrant (police, fire department, etc.), or Assume that a new dangerous area is registered from the user terminal. When the user terminal accesses the danger area notification device 1, first, the protocol control unit 1-5 sends the user ID, location name, location information (latitude, longitude), and risk received from the terminal to the input control unit 1-1. Supply (step SB1).

  The input control unit 1-1 supplies the user ID to the user information management unit 1-10 (step SB2). The user information management unit 1-10 refers to the user information table 1-4-3 of the database 1-4, acquires the role ID corresponding to the user ID, and returns it to the input control unit 1-1 (steps SB3 to SB5). ). If there is no role ID corresponding to the user ID, access is canceled.

  Next, when the role ID is returned, the input control unit 1-1 supplies the user ID, the place name, the position information (latitude, longitude), the degree of danger, and the role ID to the danger area control unit 1-3 ( Step SB6). The dangerous area control unit 1-3 registers the user ID, the place name, the position information, and the risk level in the database 1-4 (step SB7). The database 1-4 supplies the registration result (OK / NG) to the output control unit 1-2 (step SB8). The output control unit 1-2 presents the registration result to the user terminal.

  Next, the dangerous area control unit 1-3 requests user information from the user information management unit 1-10 (step SB9), and acquires the user ID and tag ID of the user (step SB10). Next, the dangerous area control unit 1-3 refers to the database 1-3 (step SB11), and acquires the position information of the monitoring target person corresponding to the tag ID (step SB12). Next, the dangerous area control unit 1-3 refers to the database 1-4 by the user ID (step SB13), acquires the position information of the dangerous area from the user ID (step SB14), and the position information of the dangerous area The position information of the monitoring subject is collated (step SB15), the danger level of the danger area where the monitoring subject exists is specified, and the communication means corresponding to the danger level is selected.

  Next, when it is determined by the above collation that the monitoring target person is in a dangerous area with a relatively low degree of risk or a non-dangerous area, the dangerous area control unit 1-3 determines the position information of the monitoring target person. Is supplied to the map information control unit 1-7, and the URL of the map information is requested (step SB16). The map information control unit 1-7 accesses the map server 5, acquires the URL of the corresponding map from the position information of the monitoring subject, and supplies it to the dangerous area control unit 1-3 (step SB17).

  Next, the dangerous area control unit 1-3 supplies the user ID to the user information management unit 1-10 (SB18), and according to the collation result, the risk level of the dangerous area where the monitoring target person exists and the user of the monitoring person The contact address registered in association with the ID is acquired (step SB19). If it is determined that the person to be monitored is in a dangerous area with a relatively low degree of risk or a non-dangerous area, the dangerous area control unit 1-3 determines the contact address, the place name, and the URL of the map. Is supplied to the mail control unit 1-8 (step SB20). The mail control unit 1-8 creates a mail from the contact address, the place name, and the URL of the map, and transmits the mail from the SMPT server 8 to the monitor.

  On the other hand, if it is determined that the person to be monitored is in a dangerous area with a relatively high degree of risk according to the collation result, the dangerous area control unit 1-3 uses the contact address as the voice communication control unit 1-9. (Step SB21). The voice communication control unit 1-9 directly connects the supervisor's telephone and the monitoring subject's mobile phone by the voice communication system 7 in accordance with the contact address. The process surrounded by the dotted line from step SB9 to SB21 is repeated for all users.

FIG. 21 is a sequence diagram for explaining an operation when entering a dangerous area (using a tag) by the dangerous area approach detection system of the present embodiment.
When the person to be monitored enters the danger area, the tag reader installed in the danger area reads the tag ID of the mobile phone carried by the person to be monitored and transmits it to the danger area entry detection device 1. In the dangerous area approach detection device 1, the protocol control unit 1-5 supplies the received tag ID, location ID, and time to the input control unit 1-1 (step SC1).

  The input control unit 1-1 supplies the tag ID, location ID, and time to the user information management unit 1-10 (step SC2). The user information management unit 1-10 refers to the database 1-4, inquires whether a user ID is registered for the tag ID (step SC3), and acquires an authentication result (OK / NG) (step SC4). . When the authentication result is OK, that is, when the user ID is registered for the tag ID, the user information management unit 1-10 supplies the user ID together with the authentication result to the input control unit 1-1 ( Step SC5).

  The input control unit 1-1 supplies the user ID, tag ID, location ID, and time to the dangerous area control unit 1-3 (step SC6). The danger area control unit 1-3 converts the location ID into location information including the latitude, longitude, and location name (step SC7), and stores the user ID, tag ID, location information, and time in the database 1-4 (location information history). Table 1-4-7) is registered (step SC8). The database 1-4 returns the registration result (OK / NG) to the dangerous area control unit 1-3 (step SC9). The dangerous area control unit 1-3 supplies the registration result (OK / NG) to the output control unit 1-2, and presents it to the user terminal from the output control unit 1-2 (step SC10).

  Next, the dangerous area control unit 1-3 refers to the database 1-4 (step SC11), acquires the position information of the dangerous area from the user ID (step SC12), the position information of the dangerous area and the monitoring target The person's position information is collated (step SC13), the danger level of the danger area where the monitoring target person exists is specified, and the communication means corresponding to the danger level is selected.

  Next, when it is determined by the above collation that the monitoring target person is in a dangerous area with a relatively low degree of risk or a non-dangerous area, the dangerous area control unit 1-3 determines the position information of the monitoring target person. Is supplied to the map information control unit 1-7, and the URL of the map information is requested (step SC14). The map information control unit 1-7 accesses the map server 5, acquires the URL of the corresponding map from the position information of the monitoring target person, and supplies it to the dangerous area control unit 1-3 (step SC15).

  Next, the dangerous area control unit 1-3 supplies the user ID to the user information management unit 1-10 (SC16), and according to the collation result, the risk level of the dangerous area where the monitoring target person exists and the user of the monitoring person The contact address registered in association with the ID is acquired (step SC17). If it is determined that the person to be monitored is in a dangerous area with a relatively low degree of risk or a non-dangerous area, the dangerous area control unit 1-3 determines the contact address, the place name, and the URL of the map. Is supplied to the mail control unit 1-8 (step SC18). The mail control unit 1-8 creates a mail from the contact address, the place name, and the URL of the map, and transmits the mail from the SMPT server 8 to the monitor.

  On the other hand, if it is determined that the person to be monitored is in a dangerous area with a relatively high degree of risk according to the collation result, the dangerous area control unit 1-3 uses the contact address as the voice communication control unit 1-9. (Step SC19). The voice communication control unit 1-9 directly connects the supervisor's telephone and the monitoring subject's mobile phone by the voice communication system 7 in accordance with the contact address.
