  Next, an embodiment of a position detection system according to the present invention will be described in detail with reference to the accompanying drawings. For example, as shown in FIG. 1, in the position detection system 10 of the present invention, a guardian's terminal 14 and a guardian's terminal 16 are connected to a mobile phone network 12, and the guardian's terminal 14 has its own GPS function. Obtain position data, receive post data from any of the plurality of position posts 18, 20, 22, 24 and 26, and notify the server 28 of terminal data based on these data. Accordingly, the context of the person to be protected is updated, and information on the person to be protected corresponding to the terminal data is notified to the guardian terminal 16. Further, in the present system 10, the mobile phone network 12 is connected to the IP (Internet Protocol) network 32 via the center 30 of the mobile operator, and the server 28 connected to the IP network 32 is connected to the protected person database (DataBase: DB). ) 34, including position post DB 36 and volunteer DB 38, to manage information on protected terminal and position post. Note that portions not directly related to understanding the present invention are not shown and redundant description is avoided.

  In this embodiment, the position detection system 10 may actually include a large number of position posts, but only a small number of position posts 18, 20, 22, 24 and 26 are shown in FIG. 1 to avoid complication. .

  In addition, the mobile phone network 12 of the present embodiment can be connected to a large number of protected terminals and guardian terminals in practice, but in order to avoid complication in FIG. 1, a small number of protected terminals 14 and Only the parent terminal 16 is shown.

  The person to be watched, that is, the guardian's terminal 14 used on the guardian's side functions as a cellular phone connected to the cellular phone network 12, and in this embodiment, in particular, an expansion unit 40 that expands the functions of the cellular phone. A detecting unit 42 that detects the status of the person to be protected, and a communication unit 44 that connects to the mobile phone network 12 and performs data communication. The protected terminal 14 has a terminal ID, the terminal ID and the user ID of the protected person are registered in the server 28, and the terminal 14 is managed by the server 28.

  The extension unit 40 has an extension function such as a GPS function. In the GPS function, the arrival time of the radio wave emitted from the GPS satellite is measured, and the distance from the satellite is calculated, thereby calculating the longitude, latitude, and height. The position of the to-be-protected person terminal 14 is detected. With this GPS function, the extension unit 40 detects the position data of the terminal 14 periodically, for example, every predetermined position transmission time, and supplies it to the communication unit 44.

  Although not shown, the detection unit 42 includes state detectors such as a microphone, an acceleration sensor, and a heart rate sensor, and periodically detects the state of the person to be protected, for example, every very short predetermined state detection time, that is, almost always. To do. The detection unit 42 detects the state of the person to be protected by judging the transition of the state of the person to be protected sensed by these state sensors, and generates an event when a specific situation is detected. Status data and an event indicating a guardian status are supplied to the communication unit 44. The detection unit 42 may unconditionally supply the situation data and the event “switch” to the communication unit 44 according to the operation of the emergency switch.

  For example, the microphone senses the sound around the person to be protected and supplies it to the detection unit 42. When the detection unit 42 determines the transition of this sound and detects “scream”, the event “scream” is generated. To the communication unit 44 together with the status data.

  The acceleration sensor senses whether the movement of the guardian is “stop”, “walking”, or “running” and supplies it to the detection unit 42, and the detection unit 42 determines the transition of this movement, When the predetermined movement is changed to another movement and the other movement continues for a predetermined abnormal movement time, an event “abnormal movement” is generated and supplied to the communication unit 44 together with the situation data.

  The heart rate sensor senses the heart rate of the person to be protected and supplies it to the detection unit 42, the detection unit 42 determines the transition of this heart rate, determines whether the heart rate corresponds to one of multiple levels, When a predetermined level is met and this continues for a predetermined abnormal heartbeat time, an event “heartbeat” is generated and supplied to the communication unit 44 together with the situation data.

  The communication unit 44 obtains position data and situation data from the extension unit 40 and the detection unit 42, respectively, generates guardian update data indicating the latest context of the guardian based on these data, and Terminal data including update data is notified to the server 28 via the mobile phone network 12 and the IP network 32. For example, every time the communication unit 44 obtains position data from the extension unit 40, it is preferable to generate protected person update data including only the position data. In addition, the communication unit 44 of the present embodiment includes the user ID and terminal ID of the protected person terminal 14 in the protected person update data and notifies the server 28 of the generated event in the terminal data.

  For example, the protected person update data may include user ID and terminal ID, which are identification information, of the protected person context as shown in FIG. 3 and data that needs to be updated.

  Further, the communication unit 44 can communicate with the position post wirelessly, receives post data from the position post, and based on this data, post update data and guardian update data indicating the latest context of the position post Is included in the terminal data including these update data and notified to the server 28.

  For example, the post update data may include a post ID that is identification information and data that needs to be updated in the position post context as shown in FIG.

  In addition, when the communication unit 44 obtains the situation data and does not obtain the post data, the communication unit 44 generates guardian update data based on the situation data and the position data, and the situation data and the post data are generated. If obtained, the guardian update data is generated based on the situation data, the position data, and the post data.

  When the communication unit 44 receives the post data of the radio signal from the position post, it measures the received electric field strength of the radio signal, and obtains the distance information between the position post and the protected terminal 14 according to the result, This distance information may be included in the guardian update data. At this time, the communication unit 44 may use the measured intensity itself as distance information, or may detect the distance between the position post and the protected terminal 14 according to the intensity and use the distance as distance information.

  Further, when the communication unit 44 receives an event and the expansion unit 40 cannot obtain the position data because the GPS function does not operate, the communication unit 44 may not include the position data in the protected person update data. Good.

  By the way, the protected terminal 14 can receive a warning and instruction from the server 28 in the communication unit 40 and can indicate it to the user by voice or display.

  For example, the protected terminal 14 has a voice means for producing a sound or a buzzer according to a warning and an instruction from the server 28, and indicates the danger level to the user by the number of times the buzzer is sounded, The user can be instructed.

  For example, when the crime prevention instruction is given to the user, this sound means sounds a buzzer once for an increase in the danger level due to the decrease in traffic, and “The nearest destination when something happens is xxx before Is a convenience store. "

  In addition, when the voice means indicates to the user that it is an emergency, in order to avoid notification of false alarms, the buzzer is repeated three times to remind the user, and the user is determined in advance accordingly. Perform the operation. If this operation is illegal or if there is no response for a certain period of time, the sound means sounds a security buzzer and utters a warning or instruction.

  The protected person terminal 14 may be an integrated terminal configured by integrating the expansion unit 40, the detection unit 42, and the communication unit 44 in the same device, but the extension unit 40, the communication unit 44, and the detection The terminal 42 may be a separate type terminal provided in a different device.

  When the protected terminal 14 is an integrated terminal, it includes all functions of a GPS mobile phone, and a wearable terminal such as a wrist device may be applied. In such an integrated terminal 14, data is mutually supplied between the expansion unit 40, the communication unit 44, and the detection unit 42 by internal processing such as a function call.

  On the other hand, when the protected terminal 14 is a separation-type terminal, the device including the extension unit 40 and the communication unit 44 may be a telephone device such as a GPS mobile phone, and the device including the detection unit 42 is the GPS mobile phone. It may be a wearable guardian status detection device such as a wrist device functioning as an option.

These telephone devices and detection devices exchange radio signals with each other to exchange information, and may use a short-range wireless system such as Bluetooth (registered trademark) or ZigBee (registered trademark) . Further, the communication of the radio signal is protected by a mechanism that is not eavesdropped such as encryption. Further, the telephone device may transmit a response signal to the detection device in response to the radio signal from the detection device.

  These telephone devices and detection devices are linked, that is, associated one-to-one, and then operate as one protected person terminal 14, and the status data detected by the detection unit 42 by the detection device 42 is transmitted by radio signals as a telephone device The telephone device receives the wireless signal of the status data at the communication unit 44.

  For example, the telephone device and the detection device are linked by linking using a link signal. The detection device operates as a slave unit, has a unique slave unit ID, and transmits a link signal including the slave unit ID. Also, the telephone device operates as a parent device, registers and stores a corresponding child device ID in advance, receives a link signal, and links if a corresponding child device ID is included.

  For example, the telephone device and the detection device operate as a parent device and a child device, respectively, and are linked by transmitting a link signal to each other and linking. These devices are identified by a slave unit ID unique to the detection device and associated one-to-one, and both of them register and store the slave unit ID in advance. Both devices transmit a link signal including the slave unit ID to each other, and link if the ID is a registered and confirmed slave unit ID of the received link signal.

  The telephone device periodically checks the reception of the link signal from the corresponding detection device, and counts the absence of reception for a predetermined number of consecutive times, or the predetermined non-reception abnormal time elapses after the reception stops. In such a case, it is determined that the link is broken, the event “link broken” is generated, and it is included in the terminal data and notified to the server 28.

  In addition, the telephone device and the detection device can perform wireless communication with each other even when the devices are not associated with each other by the close link.

  For example, if the parent device is destroyed or its power is turned off, the link signal cannot be transmitted. Therefore, when the slave unit cannot receive the link signal from the master unit and the predetermined non-reception abnormal time has elapsed, the detection unit that is the slave unit determines that the master unit is not found, Make a call to find another phone device.

  On the other hand, when the telephone device receives the close link signal from the detection device that is not its own handset, the close link with the detection device is established. The telephone device may transmit a response signal to the detecting device in response to the close link signal. In this parent-link, the detection device transmits status data to the telephone device, and the telephone device can generate terminal data based on the status data and notify the server 28 of the terminal data.

  Also, when the parent-link is established, the telephone device generates an event “parent-link”, and notifies the server 28 of the event by including it in the terminal data based on the situation data obtained from the detection device. At this time, the telephone device may notify the server 28 by including in-terminal link data such as terminal ID, handset ID, and link start time in the terminal data.

  In addition, even when the telephone device is linked to a registered detection device or is linked to a specific detection device that is not registered, the telephone device receives a parent link link signal from another detection device. You can link the differences.

  In the present embodiment, the guard terminal 16 used on the guardian, that is, the guardian side, is a communication terminal such as a mobile phone that can receive information notified from the server 28 and show it to the user.

  For example, the guardian terminal 16 registers contact information such as an e-mail address that can be received by the terminal 16 in the server 28 corresponding to the guardian terminal 14, and the position of the corresponding guardian terminal 14 It is possible to receive protected person information such as information and events from the server 28 using an electronic mail.

  The guardian terminal 16 may have voice means and display means, and may indicate the guardian information of the corresponding guardian terminal 14, and when receiving guardian information, the voice guard means 16 The buzzer is sounded, and the guardian information is displayed on the screen of the terminal 16 by the display means. For example, the screen of the terminal 16 displays the guardian information received as an e-mail as shown in FIG. 2, and displays the event time, event contents, event location, guardian status, and other details. The

  The plurality of position posts 18, 20, 22, 24, and 26 are arranged in regions where the protected person is active, and have a function of a wireless IC tag that transmits post data as its own information by a wireless signal. The multiple position posts 18, 20, 22, 24 and 26 should be arranged so that the post data can be received wherever the guardian's terminal is located in the area where the guardian is active. It should be installed in a place that is dangerous for the guardian, such as a place that cannot be reached or a place that is difficult to detect. Next, although the position post 18 will be described, the other position posts 20, 22, 24 and 26 have the same configuration and function as the position post 18.

  The position post 18 has a unique post ID, and the installed position such as latitude and longitude and the name of the position are registered in the server 28 together with the post ID, and the unique information of each position post is stored in the server 28. Managed. When the position of the position post 18 is changed, it is necessary to re-register the changed position in the server 28.

The position post 18 may include a wireless IC tag such as an active tag that is powered and operated by a battery provided therein, and periodically transmits post data as a wireless signal, such as Bluetooth (registered trademark) or ZigBee (registered trademark ). ) Or the like may be used. The position post 18 periodically transmits the post ID and the remaining battery level as post data.

  Further, the position post 18 may be provided with a human sensor to constantly detect a nearby traffic and send information indicating the traffic in the post data. For example, the position post 18 counts the number of times sensed by the human sensor during the last few minutes, and uses the number of times or the frequency according to the number of times as the traffic information.

  The server 28 is connected to the IP network 32, basically receives position data from the protected person terminal 14, detects position information of the protected person based on the position data, and protects the position information. In this embodiment, in particular, the terminal data is received and stored and managed from the terminal 14, and the guardian information is based on the event and guardian update data supplied from the terminal 14. Is generated and notified to the guardian's terminal 14 and the guardian's terminal 16 together with warnings and instructions.

  The server 28 of this embodiment includes a protected person DB 34 that stores the context of the protected person, a position post DB 36 that stores operational information of each of the plurality of position posts 18, 20, 22, 24, and 26. In addition, the system 10 includes a volunteer DB 38 for storing volunteer information for helping the guardian.

  As shown in FIG. 3, the protected person DB 34 includes a user ID, a terminal ID, position information, a post ID, distance information with respect to the position post, time, movement state, traffic, group, scream, heart rate and guardian. Stores the context of the guardian, such as contact information. The protected person DB 34 can store a plurality of protected person contexts.

  The server 28 registers fixed information related to the protected terminal such as the user ID, the terminal ID, and the guardian mail address in the protected person DB 34 in advance. When the server 28 receives the terminal data from the predetermined protected terminal 14, the server 28 refers to the protected person DB 34 using the user ID and the terminal ID in the terminal data, and detects the corresponding protected person's context. Then, the protected person update data in the terminal data is updated to the detected context.

  The guardian DB 34 can store a plurality of contacts as guardian contacts, and stores, for example, a mail address of a mobile phone owned by the guardian.

  As shown in FIG. 4, the position post DB 36 stores the position post context such as the post ID, latitude, longitude, position name, battery remaining amount and its confirmation date, and failure status and its start date and time. The position post DB 36 can store a plurality of position post contexts.

  The server 28 registers fixed information regarding the position post such as the post ID and the position name in the position post DB 36 in advance. When the server 28 receives terminal data including post-update data from a predetermined guardian's terminal 14, the server 28 refers to the position post DB 36 using the post ID in the post-update data and detects the corresponding position post. The post update data is updated to the detected position post. The server 28 may store the reception time of the terminal data in the position post context.

  As shown in FIG. 5, the volunteer DB 38 stores volunteer contexts such as volunteer names, email addresses, telephone numbers, latitudes, longitudes, and cooperation possible time zones. The volunteer DB 38 can store the contexts of a plurality of volunteers.

  In this embodiment, the volunteer is a person who is willing to help the entire protected person without being limited to a predetermined person, and may be, for example, a volunteer or a guardian. Volunteers, for example, are those who help protected persons in the vicinity of their location within the range of possible cooperation hours, providing a shelter where the protected persons run in an emergency, or being protected in a dangerous state Or asylum to the person. Volunteers register their context in the volunteer DB 38 in advance.

  Although not shown, the server 28 has a shelter DB, and registers a shelter where the protected person runs. The shelter DB should be registered not only where there are volunteers and guardians, but also public facilities and general stores that can ensure safety.

  Particularly in this embodiment, when the server 28 receives terminal data including an event from the guardian's terminal 14, the contents and position of the event, the guardian update data and the guardian according to the contents of the event. Notify parents and volunteers of guardian information obtained from the context. The server 28 detects the guardian context from the guardian DB 34 based on the guardian update data, and notifies the guardian contact information stored in the guardian context of the guardian information. In addition, the server 28 refers to the volunteer DB 38 to detect volunteers located near the event position, and notifies the detected volunteer's contact information.

  When the position data is included in the guardian update data, the server 28 may use this position data as the event position. If the position data is not included, the server 28 may detect the position post from the position post DB 36 by using the post ID in the post update data, and the position of the position post may be used as the event position or the protected person. The distance information between the terminal 14 and the position post may be obtained from the update data, and the event position may be calculated according to the position post position and the distance information.

  When receiving the event “scream”, “heartbeat”, “group leaving”, or “switch”, the server 28 of this embodiment notifies the guardian information in response to the reception of the terminal data. In the case of “abnormal movement” and “link break”, notification is made only when it is determined to be associated with the protected person context and should be notified.

  For example, when the server 28 monitors the transition of the protected person context in the protected person DB 34 and receives the event “abnormal movement”, the movement state of this context is “running” and the predetermined abnormal movement time is reached. If this context has been updated smoothly until just before the event “broken link” is received, it is determined that the parent or guardian should be notified, and the event or the guardian Notify parents and volunteers of the condition.

  Further, even when the event is not included in the terminal data, the server 28 detects the movement status of the protected person context being monitored, the traffic condition, the group, the scream and the abnormal change in the heart rate, It may be determined that abnormal behavior or danger avoidance is being performed, and the guardian or volunteer is notified of this protected person state.

  The server 28 registers in advance a “standard pattern” of the actions of the protected person, detects that the position of the protected person obtained from the terminal data is out of the “standard pattern”, and Abnormal behavior can be detected.

  However, since the guardian may intentionally deviate from the “standard pattern”, the server 28 notifies the terminal 14 that the guardian terminal 14 is out of the course for confirmation when the guardian terminal 14 deviates from the “standard pattern”. To do. The terminal 14 sounds a predetermined warning sound in response to a notice of deviation from the server 28, and causes the operator to perform a predetermined operation corresponding to the warning sound. When this operation is performed, the terminal 14 notifies the server 28 of canceling the warning. Here, even if the warning is canceled, the server 28 determines that the subject is an abnormal behavior when the departure from the “standard pattern” is repeated a predetermined number of times, and notifies the guardian. If the warning is not canceled within a certain period of time, the guardian is notified unconditionally.

  The “standard pattern” includes, for example, patterns such as attending school and attending school, and the server 28 determines the order from the post-position sequence from school to home, from school to home, from bus stop to home, and from station to home. And a pattern consisting of travel times such as school departure from 13 to 15 o'clock and cram school departure from 19 to 20 o'clock are registered in advance.

  The server 28 compares the position of the person to be protected obtained from the terminal data with the “standard pattern”, and if two or more position post checkpoints are continuously removed, the server 28 proceeds in a direction different from the original direction. If it is, it is determined that the behavior is abnormal. The server 28 may determine that the checkpoint has been removed when the post data that should not be taken according to the “standard pattern” is taken.

  Next, the operation of the position detection system 10 in this embodiment will be described with reference to the flowchart of FIG.

  In this embodiment, first, when the telephone device, that is, the parent device is activated, it is determined whether or not the position transmission time has elapsed in order to periodically transmit the position data (S102).

  If it is determined in step S102 that the position transmission time has elapsed, the process proceeds to step S104. Otherwise, the process proceeds to step S106.

  In step S106, it is determined whether or not a radio signal is received. As a result of the determination, if it is received, this radio signal is determined (SUB1), and then the process proceeds to step S104. Return to the determination in step S102.

  In step S104, the location data of the terminal 14 is measured by the extension unit 40 of the telephone device, and the guardian update data based on the location data is generated. Next, the process proceeds to step S108, where the guardian update data is stored. The included terminal data is transmitted to the server 28.

  In the telephone device according to the present embodiment, the processes in steps S102 to S108 are repeated after activation.

  By the way, in the subroutine SUB1, the telephone device operates as shown in the flowchart of FIG. 7 to determine the received radio signal, and first, it is determined whether or not the radio signal indicates the occurrence of an event (S112). .

  As a result of the determination in step S112, if an event has occurred, link processing is executed (SUB2), and then the process proceeds to return. Otherwise, the process proceeds to step S114.

  In step S114, it is determined whether or not the radio signal is post data. If the determination result is post data, the process proceeds to step S116. Otherwise, the process returns to the determination in step S102 shown in FIG. .

  In step S116, the received electric field strength of this radio signal is measured, and an RSSI (Received Signal Strength Indicator) signal is obtained as distance information between the position post and the protected terminal 14, and then the process proceeds to step S118. Post data is obtained from the radio signal, and then the process proceeds to return.

  By the way, in the subroutine SUB2, the telephone device operates as shown in the flowchart of FIG. 8 to execute link processing. First, a link signal is received (S122).

  Next, proceeding to step S124, it is determined whether the ID included in the received link signal is the same as the slave device ID registered in the telephone device. The link signal from the registered detection device, that is, the slave unit is determined.

  As a result of the determination in step S124, if the link signal is from the slave unit, the process proceeds to step S126. Otherwise, the process proceeds to step S128.

  In step S126, status data from the linked slave unit is obtained, and guardian update data based on this status data is generated (S130), and then the process proceeds to return.

  On the other hand, in step S128, it is determined whether or not the received link signal is a parent-link signal. As a result of the determination in step S128, if the link signal is a parent-link signal, an event “parent-link” is generated (S132), and then the process proceeds to return. Otherwise, the process proceeds to return.

  Next, with regard to the operation of the position detection system 10 in the present embodiment, the operation of transmitting a link signal by the detection device in the separation-type protected person terminal 14 will be described with reference to the flowchart of FIG.

  In this embodiment, first, it is determined whether or not the link transmission time has elapsed in order to periodically transmit the link signal in the detection device, that is, the slave unit (S142).

  As a result of the determination in step S142, if the link transmission time has elapsed, the process proceeds to step S144, and otherwise, the process proceeds to step S146.

  In step S146, it is determined whether or not an event has occurred in the detection unit 42 of the detection apparatus. If an event has occurred, the process proceeds to step S144. Otherwise, the process returns to the determination in step S142.

  In step S144, the detection device generates and transmits a link signal identified by the child device ID, and proceeds to step S148.

  In step S148, it is determined whether or not the link is successful according to the link signal transmitted in step S144, and it is determined that the link is successful when the link signal indicating the slave unit ID is received from the master unit.

  As a result of the determination in step S148, if the link is successful, the process proceeds to step S150, and otherwise, the process proceeds to step S152.

  In step S150, if there is an event that has occurred in the detection unit 42, the status data at that time is obtained from the detection unit 42, and is transmitted to the linked master unit together with this event. The status data to be transmitted may be identified by the handset ID.

  Next, since the detection device has succeeded in linking with the parent device regardless of the presence or absence of an event, the link failure count that is counted when the link fails is reset (step 154), and the process returns to the determination in step S142.

  On the other hand, in the detection device in step S152, since the link with the parent device has failed, the link failure count is incremented, that is, the count is incremented by one (step 154).

  If this link failure count increases, it can be determined that the slave unit is in a position where it cannot be linked from the master unit, so the detection device determines whether or not the link failure count has reached a predetermined count value (S156). .

  As a result of the determination in step S156, when the predetermined count value is reached, the process proceeds to step S158, and in other cases, the process returns to the determination in step S142.

  In step S158, a close link signal identified by the slave ID of the detection device is generated and transmitted, and the process proceeds to step S160.

  In step S160, it is determined whether the parent-link is successful according to the parent-link signal transmitted in step S158, and if the parent-link is successful when there is a response to the parent-link signal, To be judged.

  As a result of the determination in step S160, if the parent-link is successful, the process proceeds to step S162. Otherwise, the process returns to the determination in step S162.

  In step S162, the status data at that time is obtained from the detection unit 42, and is transmitted to the telephone device of the link between parents and links together with the event indicating the link between parents and the procedure returns to the determination in step S142. The status data to be transmitted may be identified by the handset ID.

  In the detection apparatus according to the present embodiment, the processes in steps S142 to S162 are repeated after activation.

  Next, the operation of the position detection system 10 in the present embodiment will be described with reference to the flowchart of FIG.

  In the present embodiment, first, when the position post 18 is activated, the human sensor is activated to sense the traffic around the position post 18 (S172).

  Further, in the position post 18, it is determined whether or not the post transmission time has elapsed in order to periodically transmit post data (S174).

  As a result of the determination in step S174, if the post transmission time has elapsed, the process proceeds to step S176, and otherwise, the process returns to step S172.

  In step S176, post data including the post ID, battery remaining amount and traffic information is generated and transmitted, and the process proceeds to step S178.

  In step S178, the timer for measuring the post transmission time in order to repeat the post data transmission is cleared, and then the process returns to step S172.

  In the position post according to the present embodiment, the processes in steps S172 to S178 are repeated after activation.

  Next, regarding the operation of the position detection system 10 in the present embodiment, the operation of processing the terminal data by the server 28 will be described with reference to the flowchart of FIG.

  In this embodiment, first, when the server is activated, the terminal data from the protected terminal 14 can be received, and the terminal data is received in step S182.

  Next, proceeding to step S184, the received terminal data is stored in the server 28. For example, the guardian update data in the terminal data is stored in the guardian DB 34, and the post update data in the terminal data is stored in the guardian DB 34 and the position post DB 36.

  Next, the process proceeds to step S186, and it is determined whether or not the terminal data includes an event. As a result of the determination, if the terminal data includes the event, the process proceeds to step S188. Otherwise, the process proceeds to step S190.

  In step S190, it is determined whether or not the person being protected is in danger avoidance based on the context of the person to be protected in the person to be protected DB 34. Otherwise, go to step S182.

  For example, in step S190, referring to the guardian DB 34 based on the guardian update data, the transition of the context such as the guardian's movement state, traffic, group scream, and heart rate is monitored. When an abnormal change is detected, it is determined that the person being protected is in danger avoidance.

  In step S188, the protected person DB 34 is referred to using the terminal ID in the protected person data, the corresponding protected person context is searched, and the guardian contact information in this context is acquired.

  Next, proceeding to step S192, the volunteer DB 38 is referred to using the location information of the terminal 14, the context of the volunteer registered at a location near this location information is searched, and the volunteer in this context is searched. Contact information is obtained. At this time, a plurality of volunteers may be searched.

  Further, the position information of the terminal 14 used in the volunteer search in step S192 may be information indicated by the position data in the protected person update data. If no location data is included, the location post DB 36 is referenced using the post ID of the post update data, the corresponding location post context is retrieved to obtain location post location information in this context, and It is preferable to obtain the distance information between the position post and the terminal 14 in the guardian update data and detect the position information of the terminal 14 by inferring from the position information and distance information of the position post.

  Next, the process proceeds to step S194, where the guardian information obtained in step S188 and the volunteer contact information obtained in step S192 are the guardian information such as the position and situation of the guardian during the event occurrence or risk avoidance. And then returns to step S182.

  In step S194, the position of the person to be notified notified may be the position information of the terminal 14 obtained in step S192. Further, the situation of the protected person to be notified may be a situation indicated by the protected person's context such as the protected person update data or the movement state obtained from the protected person DB 34 or its transition. Further, when the position information of the terminal 14 is obtained from the latest protected person context, the fact and the update date and time of the context may be notified.

  In the server 28 of the present embodiment, the processes in steps S182 to S194 are repeated after startup.

  As another embodiment, the protected terminal 14 in the position detection system 10 has a group recognition function and forms a group together with a plurality of other protected terminals based on an identifiable group ID.

  The protected terminal 14 according to the present embodiment can execute group setting, group permission, group joining, and group leaving processes as a group recognition function.

When the group setting process is activated, the protected terminal 14 transmits a group setting signal that can identify a group, for example, generates a group ID at random and sets it to itself, and transmits this group ID by a radio signal. Since the guardian terminal 14 only needs to be able to transmit this group setting signal only to other guardian terminals around it, it should be transmitted with the minimum power, such as Bluetooth (registered trademark) or ZigBee (registered trademark). A scheme may be used. The protected terminal 14 may have a group flag indicating that it is participating in a group, and set the group flag to ON when the group ID is set to itself.

  Further, when receiving the group setting signal from the group setting process, the protected terminal 14 executes the group permission process, permits participation in the group, and sets, for example, the group ID to itself.

  The protected terminal 14 participating in a predetermined group periodically transmits a confirmation signal, for example, transmits a radio signal of a group ID, and receives confirmation signals from other protected terminal, It can be confirmed that another terminal exists in the vicinity, that is, the own terminal 14 is not out of the group.

The protected terminal 14 can periodically detect the number of groups according to the received confirmation signal, and notify the server 28 of the number of groups included in the terminal data. For example, the terminal 14 identifies a unique ID for each terminal such as a Bluetooth (registered trademark) ID or a ZigBee (registered trademark) ID based on the received confirmation signal. By counting the same confirmation signal for a predetermined confirmation time, the result can be detected as the number of people in the group.

  In addition, the protected terminal 14 in a predetermined group transmits a participation signal to other protected terminals not participating in the group, for example, transmits a group ID wireless signal to perform group participation processing. Execute. The other protected terminal sets the group ID to itself according to the participation signal.

  The protected terminal 14 in the predetermined group executes the group leaving process when the user leaves the group and becomes one person. For example, if the protected terminal 14 detects the number of groups periodically according to the received confirmation signal, and the user is continuously detected during a predetermined abnormal single time, the user is It is determined that the user has left the group, and the group leaving process is executed. In the group leaving process, the protected terminal 14 terminates the transmission of the confirmation signal and notifies the server 28 of terminal data including the event “group leaving”.

  Further, in this embodiment, the server 28 receives terminal data including the number of groups from the protected person terminal 14, detects a context corresponding to the terminal 14 from the protected person DB 34, and determines the context according to the terminal data. Update.

  In addition, when the server 28 receives terminal data including the event “group leaving” from the protected terminal 14, the protected person is alone based on the terminal data and the protected context corresponding to the terminal 14. Judging that the person is in a dangerous situation that should not occur and notifying the guardian of a warning related to the event, searching for a nearby shelter from the shelter DB, and notifying the guardian of the result. Can do. Further, the server 28 may notify the guardian and nearby volunteers that the guardian is in such a dangerous situation.

  Further, in this embodiment, when the guardian terminal 14 detects the number of groups, the group ID is also included in the terminal data and notified to the server 28, and the server 28 lists the terminal ID for each group ID, You can determine who is participating in the group and even contact parents.

  Next, regarding the operation of the position detection system 10 in the present embodiment, the operation related to the group recognition function of the telephone device in the separation-type protected person terminal 14 will be described with reference to the flowchart of FIG. In FIG. 12, the flow indicated by the same reference number as the flowchart of FIG. 6 is subjected to the same processing, and the description thereof is omitted.

  In the present embodiment, first, when the telephone device as the base unit is activated, it is determined whether or not the group button has been pressed (S202). As a result, if it is pressed, the process proceeds to group generation (SUB3). Thereafter, the process returns to the determination in step S202. Otherwise, the process proceeds to the determination in step S102.

  As a result of the determination in step S102, if Yes, the process proceeds to group leaving detection (SUB4), and then proceeds to step S104. If No, the process proceeds to step S204. At this time, after step S104, the process returns to the determination of step S202 via step S108, as in the flowchart of FIG.

  In step S204, only when the group flag is ON, it is determined whether or not the confirmation signal transmission time has elapsed in order to periodically transmit the confirmation signal.

  As a result of the determination in step S204, if the confirmation signal transmission time has elapsed, the process proceeds to step S206, and otherwise, the process proceeds to step S106.

  In step S206, a group ID radio signal is transmitted as a confirmation signal, and then the process returns to the determination in step S202 via subroutine SUB4.

  In step S106, the same determination as in the flowchart of FIG. 6 is made. If Yes, the process proceeds to subroutine SUB1, and then proceeds to step S104 via subroutine SUB4. If No, the process proceeds to subroutine SUB4. Return to the determination in step S202.

By the way, the subroutine SUB1 in the flowchart of FIG. 12 is shown and described in FIG. Particularly in this embodiment, as shown in FIG. 12, if the result of the determination in step S114 in the subroutine SUB1 is No, the flow returns from a group determination is made proceed to subroutine SUB5 the determination in step S202.

  In the telephone device of this embodiment, after startup, the processing of these steps S102 to S108, S202 to S206 and subroutines SUB1 to SUB5 is repeated.

  By the way, in the subroutine SUB3, the telephone device operates as shown in the flowchart of FIG. 13 to generate a group. First, the group in the telephone device is initialized (S212).

  In step S212, internal data of group processing in the telephone device is initialized, and the group information held in the telephone device until then is reset.

  Next, proceeding to step S214, a new group ID is generated, set in the telephone device itself, and the group flag is set on.

  Next, proceeding to step S216, the radio signal indicating the group ID generated at step S214 is transmitted to the surrounding protected terminal, and then the process returns.

  By the way, in the subroutine SUB4, the telephone device operates as shown in the flowchart of FIG. 14, and the group leaving of the protected terminal 14 is detected. First, it is determined whether or not the group flag of the terminal 14 is on. (S222).

  If the result of determination in step S222 is on, the process proceeds to step S224, and otherwise, the process proceeds to return.

  In step S224, the time that has elapsed since it was determined that the terminal has not been able to receive the group confirmation signal from another terminal and has left the group is detected, and then the process proceeds to step S226.

  In step S226, it is determined whether or not the time detected in step S224 exceeds a predetermined abnormal single time. If it has exceeded, the process proceeds to step S228, and otherwise, the process proceeds to return.

  In step S228, the group leaving process is executed, the transmission of the confirmation signal is terminated, the event “group leaving” is generated, and the terminal data including this event is notified from the telephone device to the server 28, and the step in FIG. Proceed to S104.

  By the way, in the subroutine SUB5, the telephone device operates as shown in the flowchart of FIG. 15, and the group determination is performed based on the radio signal received by the guardian terminal 14. First, the group flag of the terminal 14 is turned on. It is determined whether or not (S232).

  If the result of determination in step S222 is on, the process proceeds to step S234, otherwise the process proceeds to step S236.

  In step S234, it is determined whether or not the group ID indicated by the received radio signal is the same as the group ID set in the telephone device.

  As a result of the determination in step S234, if they are the same, the process proceeds to step S238 and then shifts to return, and in other cases, shifts to return via the subroutine SUB4.

  In this step S238, the group status of this terminal 14 is updated, and for example, the time length during the participation in the group and the latest time of group status update are updated.

  In step S236, it is determined whether or not the received wireless signal is a group participation signal. If the received wireless signal is a group participation signal, the process proceeds to step S240. Otherwise, the process proceeds to return.

  In step S240, it is determined whether or not the terminal 14 performs the group permission process on the group participation signal. If so, the process proceeds to step S242. Otherwise, the process proceeds to return.

  In step S242, the group ID indicated by the group participation signal is set in the telephone device itself, the group flag is set to ON, and the process proceeds to return.

  As another example, the server 28 in the position detection system 10 is based on the terminal data from the protected person terminal 14, the protected person context in the protected person DB 34, and the position post context in the position post DB 36. It is possible to determine the position post failure and operational status.

  When the server 28 detects a failure occurring in the position post, the server 28 notifies the operation manager of the system 10 of the failure. For example, when the operation manager uses a management screen on which a position post is displayed on the map, the server 28 causes the position post on the screen where the failure has occurred to blink on the screen.

  In this embodiment, the server 28 compares the post-update data in the terminal data or the remaining battery level in the position post context with a predetermined threshold value, and if the position post is below this threshold value, the position post is faulty. Judgment can be made.

  Further, the server 28 records the radio signal receivable range of each position post in each position post context in the position post DB 36, and based on the position information and receivable range in this context, the protected person in the terminal data is recorded. Update data and post-update data can be determined to detect location post failures.

  For example, the server 28 detects the position post context from the position post DB 36 using the post ID of the post update data, and records the position data in the guardian update data as a receivable range in this context.

  In this embodiment, the predetermined position post 18 transmits post data to the protected terminal 14 at various positions, so that the terminal 14 notifies the server 28 of the updated data of the protected persons indicating various position data. To do. Thus, the server 28 can record various position data in the receivable range in the position post context corresponding to the predetermined position post 18 to obtain a more reliable receivable range.

  Further, when the server 28 receives the guardian update data including the position data and does not receive the post update data, the server 28 refers to the receivable range of each position post context in the position post DB 36, and the position data It is determined whether it falls within one of the receivable ranges. As a result, if the coverage of the predetermined position post 18 is applicable, the position post 18 may not transmit the post data, so the failure status of the context of the position post 18 in the position post DB 36 is “Unknown Change to "" and set.

  Thereafter, when the server 28 receives the post update data of the position post 18, the server 28 cancels the failure status “unknown”.

  However, if the server 28 confirms the failure status “unknown” of the position post 18 continuously for a predetermined number of abnormal times, the server 28 determines that the position post 18 has failed and operates the system 10 Notify manager of location post 18 failure.

  Further, the server 28 receives the terminal update data including the guardian update data including the position data and the post update data of the predetermined position post 18, and whether or not the position data is within the receivable range of the position post 18. If the result is out of range, the failure status of the position post 18 is changed to “theft” and set. When the server 28 confirms the failure status “theft” of the position post 18 for a predetermined number of abnormal times consecutively, the server 28 determines that the position post 18 has been moved to the operation manager of the system 10. Notify location post 18 failure.

  The position detection system of the present invention can be particularly effectively applied as a system for watching a child as a person to be protected. In this case, in the area where the child is active, not only the school gates, stations, bus stops and intersections that are the checkpoints for going to and from the school, but also the stairs and their landings, rooftops, bicycle parking lots, parking lots, corners and low traffic It can also be placed here to watch the children's trends.

  For example, when a child is out and playing, they may not be aware that they have become involved in crime because they are addicted to play and forget to say. However, according to the position detection system of the present invention, it is detected by the guardian's terminal that the player has been alone, and the post data is received from the position post installed in the dangerous place to determine the degree of danger, You can warn yourself in advance. This also allows the child to take appropriate actions such as leaving the place or preparing a security buzzer. In addition, the system can inform the child of the shelter, and the child can rush to the shelter when a crisis occurs.

  In addition, when a child goes to school or attends a school, in this system, the guardian's terminal acquires position data by GPS, receives post data from the position post, and notifies the server of terminal data based on these data Thus, the server can confirm that the child has passed the checkpoint. In addition, the server stores these update data in the database, and further accumulates past data and recognizes normal behavior patterns to detect that the behavior of children is different from normal behavior patterns, You can also notify parents who watch over their children.

  In addition, the child sometimes feels fear in an emergency and cannot press the emergency switch of the guardian's terminal. In this system, the guardian's terminal automatically detects the running state continuously when a child is chased, and also automatically detects screams and sudden increases in heart rate and notifies the server, The server can notify parents of such a child's situation.
