Description

  The present invention relates to a monitoring method capable of notifying a monitoring person of an abnormality when a person or an object to be monitored moves abnormally.

Traditionally, in order to monitor child kidnapping, lost children and elderly people (persons to be monitored),
There has been performed a method in which a portable terminal having a Global Positioning System) function is provided to a child or an elderly person, and the position information and moving speed information of the child or elderly person are transmitted wirelessly from the portable terminal.

  Each information transmitted from this portable terminal is received by the monitoring server and compared with the predicted action range and the moving speed registered in advance. Then, when the content indicated by the information transmitted from the mobile terminal deviates from the pre-registered expected behavior range or moving speed (for example, when the child is greatly away from the school road, the elderly is at 60 km / h in the middle of the night) In the case of movement, etc., a warning (for example, a telephone for notifying an abnormality from the monitoring server) is notified from this monitoring server to a guardian of a child or an elderly person (see Patent Documents 1 and 2).

In this case, since the abnormal behavior of the person to be monitored can be quickly grasped, it is possible to quickly cope with a situation such as kidnapping, lost child or habit.
JP 2004-297356 A JP 2002-027528 A

  However, in the above method, even if the monitoring target person behaves abnormally, the monitoring server warns the guardian if the moving speed is not extremely fast within the predicted action range registered in advance. Was never notified. For example, when an elderly person walks in the neighborhood (previously registered expected action range) and keeps hesitating for a long time (below the preregistered expected speed), no warning is issued.

  In addition, in the above method, there is a case where a warning is notified to the guardian from the monitoring center even though the observation target person does not actually behave abnormally. For example, when a child goes out of school route (predicted action range registered in advance) to go to a friend's house, a warning is sent to the guardian even though he is not kidnapped or lost was there.

  The present invention has been devised in view of such problems, and the problem is that when the person or object to be monitored moves abnormally, it depends on the moving speed or moving range of the person or object. And providing a monitoring method capable of determining the abnormality and notifying the monitoring person.

  The first aspect of the monitoring method according to the present invention devised to solve the above-mentioned problem is that the alarm information transmitted based on the position information indicating the position of the caller terminal is received by the receiver terminal. A monitoring method in which the receiver terminal outputs a warning based on information, a registration step for registering in the storage means a regulation condition that regulates the state of movement of the sender terminal during a predetermined period, and at regular intervals A position information acquisition step for acquiring position information indicating the position of the caller terminal; a date and time information acquisition step for acquiring date information indicating the date and time when the position information was acquired; and a position indicated by the position information. A confirmation step for confirming the state of movement of the caller terminal in comparison with the date and time order according to the information, and during a predetermined period of the caller terminal confirmed in the confirmation step An alarm notification step of transmitting alarm information to a recipient terminal when the former satisfies the latter condition. To do.

  According to the monitoring method configured as described above, the monitoring person who has the receiver terminal can register the prescribed condition in accordance with the behavior pattern of the monitored person who has the calling terminal in the registration step. For example, if the person being monitored is an elderly person, it is unlikely that the person will continue to move continuously for a long time under normal circumstances. Etc. can be registered. In addition, when the monitored person is a child, it is considered that the person who is monitored usually does not travel an extremely long distance during a certain period. "When the distance is moved" can be registered.

  According to the monitoring method of the present invention, when the state of movement of the caller terminal satisfies the registered conditions registered as described above, a warning is output by the receiver terminal. Therefore, the supervisor who has the receiver terminal can quickly grasp the abnormal behavior (the behavior that satisfies the specified condition) of the monitored person who owns the sender terminal.

  Note that the specified condition may specify that the caller terminal continues to move during the predetermined period, and the alarm notification step includes determining whether the caller terminal is moving from the state of movement during the predetermined period. A step of transmitting the alarm information to the receiver terminal when it is determined whether the sender terminal continues to move and the sender terminal continues to move during the predetermined period. There may be.

  Further, the specified condition may specify a distance that the caller terminal moves during the predetermined period, and the alarm notification step may be performed based on a movement state during the predetermined period. A step of calculating a distance traveled by the terminal, comparing the calculated distance with a distance specified in the specified condition, and transmitting the alarm information to the receiver terminal when the former exceeds the latter There may be.

  As described above, according to the present invention, when a person or an object to be monitored moves abnormally, the abnormality is determined regardless of the movement speed or movement range of the person or object. Can be provided with a monitoring method.

In addition, the receiver terminal 3 may be a mobile phone, a computer, etc. personally owned by the monitor, or a terminal lent from a security company.

  Hereinafter, the operations of the sender terminal 1, the monitoring server 2, and the receiver terminal 3 will be described with reference to FIGS. FIG. 5 is an explanatory diagram showing a series of operations of the sender terminal 1, the monitoring server 2, and the receiver terminal 3. 6 shows a flowchart showing the operation of the caller terminal 1, FIGS. 7 to 9 show a flowchart showing the operation of the monitoring server 2, and FIG. A flowchart showing the operation is described.

(Operation of caller terminal 1)
First, the operation of the caller terminal 1 will be described with reference to the flowchart of FIG.

  In the first S001, the position information acquisition unit 12 of the caller terminal 1 determines the current position of the caller terminal 1 based on the GPS signal transmitted from the GPS satellite 4 at regular time intervals (for example, every 10 minutes). The position information shown is acquired (S001 corresponds to a position information acquisition step).

  In next S002, the caller terminal 1 reads the date and time from the GPS signal, and acquires time information indicating the position information acquisition date and time. Further, the caller terminal 1 reads the model number of the caller terminal 1 from the control unit 13 and specifies its own model number. And the transmission part 14 of the sender | caller terminal 1 produces | generates the acquisition information containing the acquired positional information, time information, and a model number, and transmits this acquisition information to the monitoring server 2 from the antenna 15 wirelessly, The process according to the flowchart is terminated (S002 corresponds to a date / time information acquisition step).

(Processing by the information acquisition program 221 of the monitoring server 2)
When the monitoring server 2 receives the acquisition information from the caller terminal 1, the monitoring server 2 starts processing according to the information acquisition program 221. Hereinafter, the process by the information acquisition program 221 of the monitoring server 2 will be described with reference to the flowchart of FIG.

  When the monitoring server 2 receives the acquisition information from the caller terminal 1, the monitoring server 2 extracts the model number, the position information, and the time information of the caller terminal 1 from the acquisition information, and stores these information in the position information table 2241. Are registered in the model number field, the position information field, and the acquisition time field in the record of, and the processing according to this flowchart ends.

(Processing by the alarm determination processing program 222 of the monitoring server 2)
Subsequently, the monitoring server 2 starts processing by the alarm determination program 222. Hereinafter, processing according to the alarm determination program 222 of the monitoring server 2 will be described with reference to the flowchart of FIG.

  In step S201, the monitoring server 2 uses the model number of the caller terminal 1 corresponding to the received acquisition information, based on the model number of the corresponding model number from the alarm transmission information table 2242, the monitoring time field of the continuous movement time, the continuous movement time The conditions registered in the monitoring month / day field and the monitoring day of week field of continuous travel time are read out. When the condition registered in each field is compared with the current date and time and it is determined that the current date and time satisfies the condition registered in each field, the model number in the position information table 2241 is set. The corresponding record is extracted retroactively from the latest record by the time registered in the continuous travel time field. Further, even if no conditions are registered in the monitoring time field of continuous movement time, the monitoring month / day field of continuous movement time, and the monitoring day of week field of continuous movement time, the monitoring server 2 also stores the condition in the position information table 2241. The record corresponding to the model number is extracted retroactively from the latest record by the time registered in the continuous travel time field.

  And the monitoring server 2 compares the positional information registered in the positional information field of each extracted record, and confirms the change of positional information (confirming the positional information change corresponds to a confirmation step), It is determined whether or not the continuous movement time of the caller terminal 1 exceeds the reference time registered in the continuous movement time field. At this time, if the monitoring server 2 determines that the continuous movement time of the caller terminal 1 exceeds the reference time registered in the continuous movement time field, the process proceeds to S202, and the continuous movement time is the continuous movement time. If it is determined that the reference time registered in the field has not been exceeded, the process proceeds to S203.

  Further, the monitoring server 2 determines that the current date / time does not satisfy any of the conditions registered in the monitoring time field of the continuous movement time, the monitoring month / day field of the continuous movement time, and the monitoring day of the week of the continuous movement time. If so, the process proceeds to S203.

  In S202, the monitoring server 2 sets the alarm transmission flag information for the model number corresponding to the caller terminal 1 to ON, and advances the process to S203.

  In S203, the monitoring server 2 determines the total movement distance in the record of the corresponding model number in the alarm transmission information table 2242 based on the model number of the caller terminal 1 acquired when the acquisition information is received from the caller terminal 1. The monitoring time field, the total moving distance monitoring month / day field, and the total moving distance monitoring day field are read, and the current date and time are registered in each field by comparing the conditions registered in each field with the current date and time. When it is determined that the condition is satisfied, a record corresponding to the model number in the position information table 2241 is extracted retroactively by the unit time registered in the Total movement distance field from the latest record. In addition, the monitoring server 2 also reads from the position information table 2241 even when no conditions are registered in the total movement distance monitoring time field, the total movement distance monitoring date field, and the total movement distance monitoring day field. A record corresponding to the model number of the caller terminal 1 is extracted retroactively by the unit time registered in the Total moving distance field from the latest record.

  Then, the monitoring server 2 reads the position information field and the acquisition time field of the extracted record of the position information table 2241, and reads the position information in the position information field of the previously registered record and the position of the record registered next. The position information in the information field is sequentially compared, and the moving distance of the caller terminal 1 in each period from the acquisition of the previous position information to the acquisition of the next position information is calculated. Then, the monitoring server 2 adds the movement distances calculated in this way to calculate the total value of the movement distances.

  The monitoring server 2 compares the total value of the travel distances calculated in this way with the travel distance condition registered in the Total travel distance field in the record of the corresponding model number in the alarm transmission information table 2242. If it is determined that the former satisfies the latter condition, the process proceeds to step S204. If it is determined that the former does not satisfy the latter condition, the process according to this flowchart ends.

  The monitoring server 2 satisfies any one of the conditions registered in the monitoring time field of the total moving distance, the monitoring date field of the total moving distance, and the monitoring day of the week of the total moving distance. If it is determined that there is not, the process according to this flowchart is terminated.

  In S204, the monitoring server 2 sets the alarm transmission flag information for the model number corresponding to the caller terminal 1 to ON, and ends the processing according to this flowchart.

(Processing by the alarm transmission program 223 of the monitoring server 2)
The monitoring server 2 starts the process shown in the flowchart of FIG. 9 according to the process by the alarm transmission program 223 when the process by the alarm determination process program 222 is completed.

  In S301, the monitoring server 2 checks whether the alarm transmission flag information corresponding to the model number of the caller terminal 1 is ON.

  If the monitoring server 2 determines that the alarm transmission flag information is ON, the monitoring server 2 selects the destination registered in the destination field in the record of the corresponding model number in the alarm transmission information table 2242. The reason why the alarm transmission flag is turned on (message indicating that the vehicle has continued to move beyond the continuous movement time, message indicating that the total moving distance exceeds the registered condition, etc.) and the source terminal 1 The latest position information is transmitted (S302), and the processing according to this flowchart is terminated (S201 to S204, S301 to S302 correspond to the alarm notification step).

  If the monitoring server 2 determines that the alarm transmission flag is OFF, the monitoring server 2 ends the processing according to this flowchart.

(Operation of receiver terminal 3)
Hereinafter, the operation when the receiver terminal 3 receives an alarm signal transmitted from the monitoring server 2 will be described with reference to the flowchart of FIG.

  When receiving the alarm signal (S401), the receiver terminal 3 displays a screen corresponding to the content included in the alarm signal on its display device (S402). For example, as shown in the screen image of FIG. 15, the reason why the alarm transmission flag included in the alarm signal is turned on and the latest location information of the sender terminal 1 are displayed on the display device of the receiver terminal 3. Is displayed. As shown in the screen image of FIG. 15, the information transmitted from the monitoring server 2 to the receiver terminal 3 may include map information around the latest position of the sender terminal 1. The map information may include a map of the location information of the caller terminal 1 (latest location information and past location information), and the location information of the caller terminal 1 and the history of acquisition time may be included. It may be included.

(Specific examples for each alarm transmission condition)
Hereinafter, an operation example when specific alarm transmission conditions are registered in the alarm transmission information table 2242 according to the present embodiment of the monitoring server 2 will be described with reference to FIG.

  For example, “30 minutes or more” is registered in the continuous movement time field in the record of the model number 0001 of the alarm transmission information table 2242 in FIG. 11, and “0: 0 to 5: 00 ”is registered. In this case, if the monitored person who has the caller terminal 1 of the model number 0001 continues to move for more than 30 minutes at midnight (0:00 to 5:00), the monitoring server 2 monitors An alarm signal is transmitted to the recipient's receiver terminal 3. Therefore, if the elderly person has the caller terminal 1 of the model number 0001, it is possible to quickly confirm the late night habits of the elderly person.

  Further, “2 hours or more” is registered in the continuous movement time field in the record of the model number 0002 of the alarm transmission information table 2242 in FIG. 11, and “Saturday and Sunday” is registered in the monitoring day field of the continuous movement time. Yes. In this case, if the monitored person who has the sender terminal 1 of the model number 0002 continues to move for two hours or more on a weekend, an alarm signal is sent from the monitoring server 2 to the receiver terminal 3 of the supervisor. Is sent. Therefore, if the child who carries out the club activity possesses the caller terminal 1 of the model number 0002, it can be confirmed whether or not the child is excessively practicing (running for two hours or more) in the club activity.

  Further, “stop for 24 hours or more” is registered in the continuous movement time field in the record of the model number 0003 of the alarm transmission information table 2242 of FIG. In this case, if the monitored person who has the sender terminal 1 of the model number 0003 has not moved for more than 24 hours, an alarm signal is transmitted from the monitoring server 2 to the receiver terminal 3 of the supervisor. The Therefore, if the child has the caller terminal 1 of the model number 0003, it is possible to quickly find out if the child is kidnapped and cannot move for more than 24 hours in a confinement state, or cannot move for more than 24 hours in a fainting state.

  Further, “10 km or more / 5h” is registered in the Total movement distance field of the record of the model number 0004 in the alarm transmission information table 2242 of FIG. In this case, if the monitored person who has the sender terminal 1 of the model number 0004 moves 10 km or more within 5 hours, an alarm is sent from the monitoring server 2 to the receiver terminal 3 of the supervisor. A signal is transmitted. For this reason, if the pet has the caller terminal 1 of the model number 0004, the case where the pet is taken away by car or the like can be detected at an early stage.

  Further, “1 km or less / 24h” is registered in the Total movement distance field of the record of the model number 0005 in the alarm transmission information table 2242 of FIG. In this case, if the monitored person who has the caller terminal 1 of the model number 0005 has moved within 1 km or less within 24 hours, the monitoring server 2 receives the monitoring receiver terminal. An alarm signal is transmitted to 3. Therefore, if the child has the caller terminal 1 of the model number 0005, the case where the child is confined can be detected early. In this case, if an alarm signal is transmitted even though the supervisor knows the location of the child, it is understood that the child is not moving extremely in one day. You will see that there is.

  As described above, according to the present embodiment, the monitoring server 2 can transmit an alarm signal to the receiver terminal 3 in accordance with the continuous travel time and the total travel distance of the caller terminal 1. The abnormality can be notified to the monitor regardless of the moving speed or the action range.

  In the second embodiment of the present invention, as compared with the first embodiment, the caller terminal 100 that can calculate the continuous travel time and the total travel distance is used instead of the caller terminal 1, and this caller. The point that the alarm signal is directly transmitted from the terminal 100 to the receiver terminal 3 is different from the point that the monitoring server 2 is not provided. Hereinafter, the caller terminal 100 in the present embodiment will be described with reference to FIG.

  FIG. 12 is a block diagram showing the internal configuration of the caller terminal 100 in the second embodiment. As shown in FIG. 12, a caller terminal 100 includes a receiving antenna 111 that receives a GPS signal, a position information acquisition unit 112 that acquires position information per unit time based on the received GPS signal, and the caller terminal 100. A control unit 113 that performs overall control, an alarm transmission unit 114 that generates an alarm signal for transmission to the receiver terminal 3, a transmission antenna 115 for transmitting the alarm signal wirelessly, and each unit of the caller terminal 100 A battery 116 for supplying power, a motion information acquisition unit 117 that can detect the movement (acceleration) of the caller terminal 100, and an alarm determination unit 118 that determines whether or not to transmit an alarm signal. Yes.

  The motion information acquisition unit 117 includes a triaxial acceleration sensor, and can separately detect the acceleration associated with the movement of the caller terminal 100 in each of the three orthogonal directions. If the acceleration detected by the three-axis acceleration sensor is integrated, the moving speed can be calculated. If the acceleration is further integrated, the moving distance can be calculated. Therefore, even if the caller terminal 100 cannot receive a GPS signal (for example, in a tunnel), if the acceleration detected by the three-axis acceleration sensor is used, the position where the GPS signal was last received is used. Since the movement distance from each of the three axes can be calculated, position information corresponding to the actual position at that time can be calculated.

  The alarm determination unit 118 has a database 324 having a data structure similar to that of the database 224 of the monitoring server 2 in the first embodiment. In this embodiment, information (conditions such as continuous travel time and total travel distance) registered in advance in the record of the alarm transmission information table 3242 of the database 324 is uploaded from the receiver terminal 3 by radio or the like, for example. Is possible. Also, the alarm determination unit 118 sends the caller to the position information field and the acquisition time field of the position information table 3241 of the database 324 according to the position information acquired by the position information acquisition unit 112 and the acquisition time acquired from the GPS signal. It has a function of registering location information and acquisition time of the terminal 100. Note that when the caller terminal 100 cannot receive a GPS signal, the alarm determination unit 118 obtains the position information that can be acquired by the motion information acquisition unit 117 as described above, the position information field of the position information table 3241 of the database 324, and the acquisition time. It may be configured to register in the field.

  The alarm determination unit 118 performs the same processing as the processing by the alarm determination program 222 in the monitoring server 2 of the first embodiment, and the continuous travel time registered in advance in the record of the alarm transmission information table 3242 of the database 324. And the function of determining whether or not the caller terminal 100 satisfies the conditions of the total moving distance and the like.

  When the alarm determination unit 118 determines that the caller terminal 100 satisfies the conditions such as the continuous travel time and the total travel distance, the alarm transmission unit 114 generates an alarm signal similar to the alarm signal in the first embodiment. It is created and transmitted directly from the antenna 115 to the receiver terminal 3 of the supervisor by radio.

  Therefore, according to the present embodiment, the monitor can receive the alarm signal transmitted from the caller terminal 100 by the receiver terminal 3 even if the monitoring server 2 is not included in the monitoring system. It becomes possible to know abnormal movement and movement.

  In the present embodiment, since the motion information acquisition unit 117 can detect the movement of the caller terminal 100, it is possible to check the operation state of the monitored person (for example, if the monitored person is confined or When it cannot move at all due to fainting, the state where the acceleration of the caller terminal 100 does not change at all continues for a long time, and when the monitored person is exercising vigorously, the acceleration of the caller terminal 100 Change frequently). Therefore, information acquired by the motion information acquisition unit 117 may be used as a determination condition for transmitting the alarm signal.

  In the third embodiment of the present invention, paying attention to the fact that popular items are often picked up and moved from the display shelf many times, the displayed item 60 is similar to the caller terminal 1. A feature is that a RFID (Radio Frequency Identification) 70 (hereinafter referred to as an RF tag 70) having a function is attached. Further, in the third embodiment, in comparison with the first embodiment, the field intensity of radio waves transmitted from a large number of antennas 50 is compared instead of the position measurement method using the GPS signal from the GPS satellite 4. Thus, a method of specifying the position by the principle of three-point surveying is adopted. The receiver terminal 3 is owned by the sales clerk of the store that sells the product 60.

  FIG. 13 is an explanatory diagram showing the principle of position measurement in the third embodiment. As shown in FIG. 13, an RF tag 70 is attached to a plurality of products 60 (only one is illustrated in FIG. 13), and a plurality of antennas 50 for transmitting radio waves are provided above the products 60. ing.

  The antennas 50 have different identification numbers, and radio waves including information on the identification numbers are transmitted from the respective antennas 50. Therefore, since the RF tag 70 can distinguish the radio waves transmitted from the antennas 50, the RF tag 70 compares itself with the reception intensity of the radio waves transmitted from at least three antennas 50 according to the principle of three-point surveying. Can be specified. Therefore, also in the third embodiment, an alarm signal can be transmitted from the monitoring server 2 to the receiver terminal 3 in accordance with the movement status of the RF tag 70 as in the first embodiment.

  FIG. 14 shows the data structure of the alarm transmission information table 2243 in the third embodiment. As shown in FIG. 14, “100 m or more / 24h” is registered in the Total movement distance field of the record of model number 0001 in the alarm transmission information table 2243. In this case, an alarm signal is notified to the receiver terminal 3 when the product 60 is picked up several times in one day and is moved 100 m or more in total. Therefore, in this case, the sales clerk of the sales store knows that the product 60 to which the RF tag 70 of the model number 0001 is attached is frequently moved, so that the product 60 is not out of stock from the sales shelf early. Can be replenished. Further, since the salesclerk of the sales store knows that the product has a high degree of attention when the alarm signal is notified, it can place a large number of products for which the alarm signal has been notified at the time of ordering the next product. .

  In the first and second embodiments, the position information is acquired based on the GPS signal. However, the method for acquiring the position information is not limited to this. For example, as a method of acquiring position information, a method of acquiring position information based on radio waves transmitted from a PHS base station may be employed.

  Further, in the third embodiment, the RF tag 70 itself calculates the position information. However, the electric field intensity of the radio wave emitted from the RF tag 70 is measured by the antenna 50, and the server device 2 side measures the RF tag 70. The position may be specified. Specifically, radio waves emitted from the RF tag 70 are received by at least three antennas 50, and the electric field strength of the received radio waves is measured for each antenna 50, and the principle of three-point surveying is performed according to the electric field strength. The position information may be calculated on the monitoring server 2 side based on the above. In this case, since it is not necessary to provide a configuration for performing position measurement on the RF tag 70, the configuration of the RF tag 70 can be simplified.
