In the safety confirmation system and the safety confirmation method according to the present embodiment, the biological information detected by the sensor worn by the safety confirmation target person and the activity information detected by the sensor set in the monitoring area are transmitted to the monitoring center in advance. An abnormality is detected based on a set threshold value.

  First, a configuration example of a safety confirmation system to which the present invention is applied will be described. FIG. 1 is a block diagram showing a configuration of a safety confirmation system according to the present embodiment. A safety confirmation system 10 according to the present embodiment includes a monitored person information detection device 100, a monitoring center 200, and a mobile terminal 300. The monitored person information detection apparatus 100, the monitoring center 200, and the portable terminal 300 are connected via a network 400 such as a telephone line, a wireless network, or the Internet.

  A monitored person information detection apparatus 100 according to the present embodiment includes a biological information detection unit 101, a timer unit 102, an activity information detection unit 103, a transmission / reception unit 104, a monitoring setting unit 105, and a monitoring setting storage unit 106. And a recovery information input unit 107, a prior information output unit 108, a biological information sensor 110, and an activity information sensor 120.

  The biological information sensor 110 is a sensor that detects biological information of the monitored person 1 when the monitored person wears the body. The biological information sensor 110 is, for example, a wristwatch-type acceleration sensor that detects the operation of the monitored person 1, a wristwatch-type pulse detection sensor that detects the pulse of the monitored person 1, and the like.

  The activity information sensor 120 is a sensor that detects that the monitored person 1 is performing a normal activity in the monitoring area. The activity information sensor 120 is, for example, an infrared human body detection sensor set at a predetermined location in the monitoring area, a sensor (for example, a magnet sensor) that detects opening / closing of a toilet door, and detection of toilet water flowing A sensor that detects the use of tap water, and the like.

  The biological information detection unit 101 receives an input of a signal transmitted from the biological information sensor 110. Specifically, in the case of an acceleration sensor, information on whether or not an operation has been detected within a predetermined time measured by a timer unit 102 described later is transmitted from the transmission / reception unit 104 described later to the monitoring center 200. In the case of a pulse detection sensor, information indicating whether or not a predetermined pulse has been detected within a predetermined time is transmitted from the transmission / reception unit 104 to the monitoring center 200.

  The activity information detection unit 103 receives an input of a signal transmitted by the activity information sensor 120. Specifically, in the case of an infrared human body detection sensor, information indicating whether or not a human body has been detected within a predetermined time measured by a timer unit 102 described later is transmitted from the transmission / reception unit 104 to the monitoring center 200. Moreover, if it is a sensor which detects opening / closing of the door of a toilet, the information of whether the door was opened / closed within the predetermined time will be detected. If it is a sensor that detects the flow of water in the toilet, it detects information on whether or not water has flowed within a predetermined time. If it is a sensor which detects use of water supply, the information of whether the water supply was used within the predetermined time will be detected.

  The timer unit 102 measures a predetermined time during which the biological information detection unit 101 receives an input of a signal transmitted from the biological information sensor 110 and a predetermined time during which the activity information detection unit 103 receives an input of a signal transmitted from the activity information sensor 120. To do.

  The transmission / reception unit 104 transmits detection information detected by the biological information detection unit 101 and the activity information detection unit 103 to the monitoring center 200. Further, the recovery information received by the recovery information input unit 107 described later is transmitted to the monitoring center 200, and prior information transmitted from the monitoring center 200 is received. The transmission / reception unit 104 constitutes a detection information transmission unit, a monitoring setting transmission unit, a recovery information transmission unit, and a prior information reception unit according to the present invention.

  The monitoring setting unit 105 accepts the setting of the monitoring mode or the monitoring cancellation mode. Here, the monitoring mode refers to a state in which the biological information detected by the biological information detection unit 101 and the activity information detected by the activity information detection unit 103 are transmitted to the monitoring center 200. The monitoring release mode is a state in which the biological information detected by the biological information detection unit 101 and the activity information detected by the activity information detection unit 103 are not transmitted, or the biological information and activity information detected by the biological information detection unit 101 This is a state in which activity information detected by the detection unit 103 is transmitted but the monitoring center 200 does not determine any abnormality.

  The monitoring setting storage unit 106 stores the monitoring mode or the monitoring cancellation mode set by the monitoring setting unit 105.

  The recovery information input unit 107 receives input of recovery information. For example, the recovery information is input by pressing a recovery button or the like present in the monitored person information detection apparatus. Here, the recovery information is a response information from the time when the recovery information is transmitted by clearing the value of the response information counted for use in determining whether or not an abnormality has occurred in the monitoring center 200. This is information for instructing to start abnormality counting and determine abnormality. Here, the reaction information includes the count of the number of “no biological reaction” transmitted from the monitored person information detection device 100 to the monitoring center 200 as the biological information, and the monitoring center 200 from the monitored person information detection device 100. This is a count of the number of times “no activity response” is transmitted as activity information.

  The prior information output unit 108 outputs prior information that is transmitted before alarm information is transmitted when the monitoring center 200 determines abnormality. Here, the prior information means that when the monitoring center 200 determines the abnormality of the monitored person, the alarm information is transmitted to a predetermined report destination. However, before the alarm information is transmitted, the monitoring center 200 actually transmits the alarm information to the monitored person. This is information for confirming whether or not an abnormality has occurred. Specifically, a buzzer sound or a voice message for alerting the monitored person. If the person to be monitored outputs the prior information, if there is no abnormality in the person to be monitored, the person to be recovered inputs the recovery information from the above-mentioned recovery information input unit 107, for example, moves his arm, or opens the toilet door. The detection information detected by the biological information detection unit 101 and the activity information detection unit 103 is transmitted to the monitoring center 200 by opening and closing, and the alarm information is not transmitted in the monitoring center 200.

  The monitoring center 200 according to the present embodiment includes a transmission destination storage unit 201, a reaction information storage unit 202, a transmission / reception unit 203, an abnormality determination unit 204, a prior determination unit 205, and a threshold storage unit 206. Yes.

  The transmission destination storage unit 201 stores a transmission destination for transmitting alarm information when an abnormality is determined by an abnormality determination unit 204 described later. One transmission destination may be stored for one monitoring destination, or a plurality of transmission destinations may be stored. When storing a plurality of transmission destinations, the transmission destinations may be transmitted to all the transmission destinations when it is determined to be abnormal, or the number of transmission destinations and the transmission destinations may be changed according to the urgent level of the alarm.

  The reaction information storage unit 202 stores values of biological reaction information and activity reaction information. Here, the biological reaction information is the number of times “no biological reaction” is continuously transmitted in the biological information transmitted from the monitored person information detection apparatus 100. The activity response information is the number of times “no activity response” is continuously transmitted in the activity information transmitted from the monitored person information detection apparatus 100.

  The transmission / reception unit 203 receives the detection information transmitted from the monitored person information detection apparatus 100. When the abnormality determination unit 204 described later determines that an abnormality has occurred in the monitored person, the alarm information is transmitted to the mobile terminal 300 that is set in advance as a report destination. In addition, threshold information for determining the abnormality of the monitored person is received. Further, the abnormality determination unit 204 transmits prior information indicating a previous stage in which it is determined that an abnormality has occurred in the monitored person. The transmission / reception unit 203 constitutes detection information reception means, alarm transmission means, threshold value reception means, monitoring setting reception means, recovery information reception means, and advance information transmission means according to the present invention.

  The abnormality determination unit 204 is based on threshold information stored in a threshold storage unit 206 (to be described later) based on biological reaction information and activity response information counted by the detection information transmitted from the monitored person information detection device 100. Whether or not an abnormality has occurred is determined.

  The prior determination unit 205 generates an abnormality based on threshold information stored in a threshold storage unit 206 (to be described later) from biological reaction information or activity response information counted by the detection information transmitted from the monitored person information detection device 100. It is determined whether or not it is a previous stage in which it is determined that it has been performed.

  The threshold value storage unit 206 defines a threshold value for determining whether or not an abnormality has occurred in the monitored person, and the risk level of the abnormality that has occurred. FIG. 2 is an explanatory diagram illustrating an example of a data configuration of the threshold storage unit. The threshold storage unit 206 stores threshold information including the number of times of no biological reaction, the number of times of no activity information, and the degree of risk.

  The mobile terminal 300 according to the present embodiment receives alarm information transmitted from the monitoring center 200. The mobile terminal 300 is specifically a mobile phone or the like, and is carried by a person who requests monitoring of the monitored person, that is, the family of the monitored person.

  Next, detection information transmission processing by the monitored person information detection apparatus configured as described above will be described. FIG. 3 is a flowchart illustrating a detection information transmission processing procedure performed by the monitoring setting unit, the timer unit, the biological information detection unit, the activity information detection unit, and the transmission / reception unit.

  First, the power is turned on. Next, the timer unit 102 starts measuring elapsed time (step S3001). It is determined whether or not the power is turned off (step S3002). If it is determined that the power has been turned off (step S3002: Yes), the process ends. If it is determined that the power is not turned off (step S3002: No), the monitoring setting unit 105 determines whether an input for monitoring setting has been received (step S3003). When it is determined that the monitoring setting input has been accepted (step S3003: Yes), the monitoring setting unit 105 stores the monitoring setting input to the monitoring setting storage unit 106 (step S3004). Specifically, “monitor mode” or “monitor release mode” is stored as the monitor setting. Note that “security mode” is stored as an initial setting. If it is determined that the monitoring setting input has not been accepted (step S3003: NO), the process proceeds to step S3005.

  The timer unit 102 determines whether or not a predetermined time has elapsed (step S3005). When it is determined that the predetermined time has not elapsed (step S3005: No), the biological information detection unit 101 determines whether a detection signal is detected from the biological information sensor 110 (step S3006). When it is determined that the detection signal is detected from the biological information sensor 110 (step S3006: Yes), “with biological reaction” is set as the biological information (step S3007). If it is determined that the detection signal is not detected from the biological information sensor 110 (step S3006: No), the process proceeds to step S3008.

  That is, when it is determined that the detection signal is not detected from the biometric information sensor 110, the process is not performed. "Is still set" and when the detection signal is detected, "there is biological reaction" is set in the biological information, and "there is no biological reaction" is maintained even if the detection signal is not detected thereafter. The Rukoto.

  The activity information detection unit 103 determines whether a detection signal is detected from the activity information sensor 120 (step S3008). If it is determined that the detection signal is detected from the activity information sensor 120 (step S3008: Yes), “activity reaction is present” is set as the activity information (step S3009), and the process returns to step S3002. When it is determined that the detection signal is not detected from the activity information sensor 120 (step S3008: No), the process returns to step S3002.

  As in the case of step S3006, when it is determined that the detection signal is not detected from the activity information sensor 120, the process is not performed. “No activity response” is still set, and if a detection signal is detected, “Activity response” is set in the activity information, and even if no detection signal is detected after that, “Activity” “Reaction” is retained.

  If it is determined in step S3005 that the predetermined time has elapsed (step S3005: Yes), the transmission / reception unit 104 acquires the current monitoring setting from the monitoring setting storage unit 106 (step S3010). The transmission / reception unit 104 determines whether or not the current monitoring setting is “monitoring mode” (step S3011).

  If it is determined that the current monitoring setting is “monitoring mode” (step S3011: Yes), the transmission / reception unit 104 transmits biological information and activity information to the monitoring center 200 (step S3012). The transmission / reception unit 104 sets “no biological reaction” as the biological information and “no activity information” as the activity information (step S3013). The timer unit 102 resets the timer (step S3014) and returns to step S3001. If it is determined that the current monitoring setting is not “monitoring mode” (step S3011: No), the process returns to step S3001.

  In this flowchart, it is determined whether or not the monitoring setting stored in the monitoring setting storage unit 106 is “monitoring mode” in step S3011, and whether or not the biological information and the activity information are transmitted to the monitoring center 200 is determined. The monitoring setting input by the monitoring setting unit 105, that is, the “monitoring mode” or the “monitoring release mode” is transmitted to the monitoring center 200 in advance, and the monitored person information detecting apparatus 100 performs the monitoring setting. It is also possible to transmit the biological information and activity information without determining whether or not to perform abnormality determination on the monitoring center 200 side.

  The abnormality determination process by the monitoring center 200 will be described. FIGS. 4-1 to 4-3 are flowcharts illustrating the abnormality determination / alarm transmission processing procedure performed by the transmission / reception unit, the abnormality determination unit, and the prior determination unit.

  First, the transmission / reception unit 203 receives the biological information and activity information transmitted from the monitored person information detection apparatus 100 (step S4001). The abnormality determination unit 204 acquires biological reaction information and activity reaction information from the reaction information storage unit 202 (step S4002). The abnormality determination unit 204 determines whether or not the transmitted biological information is “no biological reaction” (step S4003).

  When it is determined that the transmitted biological information is “no biological reaction” (step S4003: Yes), the biological reaction information is counted up by one (step S4004). If it is determined that the transmitted biological information is not “no biological reaction”, ie, “there is biological reaction” (step S4003: No), the biological reaction information is cleared (step S4005). That is, 0 is set in the biological reaction information.

  The abnormality determination unit 204 determines whether or not the transmitted activity information is “no activity response” (step S4006). When it is determined that the transmitted activity information is “no activity response” (step S4006: Yes), the abnormality determination unit 204 increments the activity response information by 1 (step S4007). When it is determined that the transmitted activity information is not “no activity response”, that is, “there is an activity response” (step S4006: No), the abnormality determination unit 204 clears the activity response information (step S4008). That is, 0 is set in the activity response information.

  The abnormality determination unit 204 stores the biological reaction information and the activity reaction information in the reaction information storage unit (step S4009). The abnormality determination unit 204 acquires each threshold value from the threshold value storage unit 206 (step S4010). The transmission / reception unit 203 acquires a transmission destination from the transmission destination storage unit 201 (step S4011). The prior determination unit 205 determines whether or not the biological reaction information is threshold value -1 or the activity reaction information is threshold value -1 (step S4012). Specifically, referring to FIG. 2, since the number of no biological reactions is “3”, if the current biological reaction information is 3-1 = 2, it is determined that the biological reaction information is the threshold value−1. In addition, since the number of times of no activity response is “10”, if the current activity response information is 10−1 = 9, it is determined that the activity response information is the threshold value−1.

  When it is determined that the biological reaction information is the threshold value -1 or the activity reaction information is the threshold value -1 (step S4012: Yes), the transmission / reception unit 203 transmits the advance information to the monitored person information detection device 100. It transmits to the transmission destination acquired from the memory | storage part 201 (step S4013). If it is determined that the biological reaction information is not threshold value -1 and the activity response information is not threshold value -1 (step S4012: No), the process proceeds to step S4014.

  The abnormality determination unit 204 determines whether or not the biological reaction information is greater than or equal to a threshold value (step S4014). For example, referring to FIG. 2, since the threshold value for the number of times of no biological reaction is 3, it is determined whether or not the biological reaction information is 3 or more. When it is determined that the biological reaction information is greater than or equal to the threshold (step S4014: Yes), the transmission / reception unit 203 transmits alarm information with a low degree of urgency (step S4015). Specifically, an electronic mail indicating that the alarm is a low risk is transmitted to the mobile terminal 300. When it is determined that the biological reaction information is not equal to or greater than the threshold (step S4014: No), the process proceeds to step S4016.

  The abnormality determination unit 204 determines whether or not the activity response information is greater than or equal to a threshold value (step S4016). For example, referring to FIG. 2, since the threshold value for the number of times of no activity information is 10, it is determined whether or not the activity response information is 10 or more. If it is determined that the activity response information is greater than or equal to the threshold (step S4016: Yes), the transmission / reception unit 203 transmits alarm information as indicating the degree of urgency. Specifically, an electronic mail indicating that the alarm is in danger is transmitted to the mobile terminal 300. In this case, in addition to sending an e-mail indicating that the alarm is in danger, an automatic voice indicating that the alarm is in danger may be reported by telephone. If it is determined that the activity response information is not greater than or equal to the threshold (step S4016: No), the process proceeds to step S4018.

  The abnormality detection unit 204 determines whether the biological reaction information is greater than or equal to the threshold and the activity response information is greater than or equal to the threshold (step S4018). When it is determined that the biological reaction information is greater than or equal to the threshold and the activity response information is greater than or equal to the threshold (step S4018: Yes), the transmission / reception unit 203 transmits alarm information with a high degree of urgency (step S4019). Specifically, an e-mail indicating that the alarm is of a high degree of danger is transmitted to the mobile terminal 300, and an automatic voice indicating that an abnormality has occurred is reported to the monitored person by telephone. Note that the mobile terminal 300 that transmits the alarm is not limited to one reporting destination, and may be transmitted to a plurality of reporting destinations registered in advance. If it is determined that the biological response information is not equal to or greater than the threshold value or the activity response information is not equal to or greater than the threshold value (step S4018: No), the process is terminated.

  In the above-described flowchart, for example, when the biological information is “no biological reaction” three times in succession and the activity information is transmitted “no activity reaction” ten times in succession, the alarm information and the risk level are low. The alarm information in the middle and the alarm information with a high risk level are transmitted at a time. In such a case, only the alarm information with a high risk level may be transmitted. For example, the transmission / reception unit 203 may first perform the determination in step S4018 before performing the determination in step S4014 and the determination in step S4016, and if yes, transmit warning information with a high degree of risk to exit the process. .

  In this way, since it is possible to confirm the safety of the monitored person using the detection information of both the biological information and the activity information, compared to the case where the safety of the monitored person is confirmed using one of the detection information, a false alarm is generated. Can be suppressed. Also, in order to determine the degree of abnormalities occurring in the monitored person and send an alarm corresponding to the degree of danger, the user who requested monitoring of the monitored person should take action according to the abnormal degree of risk. In addition to being able to respond to the monitored person in detail, the monitoring person can also perform efficient monitoring without waste.

  In addition, on the monitored person information detection device side, the biological information and activity information detected by the sensor are transmitted to the monitoring center without being stored in the storage unit, and the monitored person information detection device side makes an abnormality due to the biological information and activity information. Since the determination process is not performed, the monitored person information detection apparatus can be provided as an inexpensive apparatus.

  Furthermore, since the information received by the monitoring center from the monitored person information detection device is the sensor operating state at every predetermined time and is not an alarm stipulated by the Security Business Law, security companies, etc. are restricted under the Security Business Law. Not receive. Therefore, even if an abnormality is determined at the monitoring center, it is not always necessary to dispatch a security guard according to the security business law, so that a service that meets the needs of the customer can be provided.

  Next, recovery information transmission / reception processing in the monitored person information detection apparatus 100 and the monitoring center 200 will be described. FIG. 5 is a flowchart illustrating a recovery information transmission / reception processing procedure performed by the recovery information input unit, the transmission / reception unit, the transmission / reception unit of the monitoring center, and the abnormality determination unit of the monitored person information detection apparatus.

  First, in the monitored person information detection apparatus 100, the recovery information input unit 107 determines whether or not input of recovery information has been accepted (step S5001). If it is determined that the input of recovery information is not accepted (step S5001: No), the process returns to step S5001. If it is determined that the recovery information has been input (step S5001: Yes), the transmission / reception unit 104 transmits the recovery information to the monitoring center 200 (step S5002).

  In the monitoring center 200, the transmission / reception unit 203 receives the recovery information transmitted from the monitored person information detection apparatus 100 (step S5003). The abnormality determination unit 204 stores 0 in the biological reaction information in the reaction information storage unit 202 and 0 in the activity reaction information (step S5004).

  As described above, the monitored person inputs the recovery information and transmits the input recovery information to the monitoring center, thereby clearing the biological reaction information and the activity reaction information. Even if the detection information “having a biological reaction” or “having an activity reaction” is not detected by chance, such as when the information sensor 110 is removed from the body or the toilet is not taken for a long time, the operation of the monitored person Can prevent the occurrence of false alarms.

  Next, threshold information reception processing in the monitoring center 200 will be described. FIG. 6 is a flowchart illustrating a threshold information reception processing procedure performed by the transmission / reception unit of the monitoring center.

  First, the transmission / reception unit 203 of the monitoring center 200 receives threshold information from the mobile terminal 300 or a user terminal device connected to a network (not shown) (step S6001). Next, the transmission / reception unit 203 stores the received threshold information in the threshold storage unit 206 (step S6002). Specifically, with reference to FIG. 2, for example, “5” is set instead of “3” set as the number of times of no biological reaction.

  In this way, the threshold value for transmitting the alarm information can be set freely, so that the threshold value can be set in accordance with the accuracy of the sensor worn by the monitored person and the actual life of the monitored person. Confirmation can be made and the occurrence of false alarms can be prevented.

  Next, the prior information reception process in the monitored person information detection apparatus 100 will be described. FIG. 7 is a flowchart showing a prior information reception processing procedure performed by the transmission / reception unit of the monitoring center.

  First, the transmission / reception unit 104 of the monitored person information detection apparatus 100 receives the advance information transmitted from the monitoring center 200 (step S7001). Next, the advance information output unit 108 outputs the received advance information (step S7002). Specifically, the prior information output unit 108 outputs a voice message indicating that no biological reaction or activity reaction is detected, a buzzer sound for alerting the monitored person, and the like.

  In this way, since the alarm information indicating that the abnormality has occurred in the monitored person can be alerted to the monitored person before sending to the portable terminal, the monitored person is normal and has no abnormality. If no biometric information or activity information is detected by accident, the above recovery information can be transmitted or the sensor can be detected to be in an abnormal state. it can.

  The alarm information transmission processing described with reference to FIGS. 4-1 to 4-3 will be described using a specific example. FIG. 8 is an explanatory diagram showing the relationship between the reception result of the biological information and activity information and the alarm transmission. Since “no biological reaction” is received three consecutive times as reception information “9:40”, “9:50”, “10:00” as biological information (step S4014 in FIG. 4-2: Yes). ), The first alarm (low alarm) is transmitted at “10:00” (step S4015).

  Next, since “no activity response” is continuously received 10 times from the reception time “9:00” to “10:30” as the activity information (step S4016: Yes), the activity information is changed to “10:30”. The second warning (warning warning) is transmitted (step S4017). Furthermore, “no biological reaction” is received three times continuously as reception information “10:40”, “10:50”, “11:00” as biological information, and reception time “9:30” as activity information. Since “No activity response” has been received ten times continuously from “11:00” to “11:00” (step S4018: Yes), a third alarm (high alarm) is issued at “11:00”. Has been transmitted (step S4019).
