Therefore, the imaging direction by the camera device 101 is approximately the same direction as the direction of the target child's line of sight. The recorder device 102 is housed in a housing case 14 exclusively for the recorder device 102 formed on the right side surface 13 of the school bag 1. This makes the recorder device 102 less likely to be damaged even if it receives an external shock. Further, the storage case 14 has a lockable structure so that the recorder device 102 inside cannot be removed. An opening 14a is formed in the storage case 14 so that the switch part 127 can be pressed by the child's fingertip.

A portion of the cable 103 connected to the camera device 101 is fixed to the surface of the shoulder belt 12. The cable 103 passes through the inside of the school bag 1 from an opening (not shown) formed in the back support surface 11 and into the storage case 14 from an opening (not shown) formed in the right side surface 13 and the storage case 14. , and its tip is connected to the recorder device 102 housed in the housing case 14 .

The camera device 101 includes a rectangular parallelepiped housing 101a and an imaging lens 101b. Furthermore, an LED (Light Emitting Diode) 101c is provided at the upper right end of the surface of the housing 101a on which the imaging lens 101b is provided. Furthermore, the LED 101c of the camera device 101 lights up during its operation. As a result, the camera device 101 can make people around the target child aware that the camera device 101 is operating, that is, capturing and recording images, and can threaten people around the child. It is possible to demonstrate the effect of As a result, children wearing school bags 1 can go to and from school more safely.

The camera device 101 is a device that is capable of not only capturing images but also recording audio, as will be described later. The monitoring device 100 uses such a camera device 101 to capture an image in substantially the same direction as the target child's line of sight as information for monitoring the target child wearing the school bag 1 (this is referred to as "monitoring information"). (This is also referred to as "image monitoring information.") Along with this, the sounds surrounding the target child (this is also referred to as "audio monitoring information.") are acquired.

In the monitoring device 100, image monitoring information and audio monitoring information acquired by the camera device 101 are transmitted to the recorder device 102 housed in the housing case 14 via the cable 103. The recorder device 102 stores image monitoring information and audio monitoring information transmitted from the camera device 101.

The recorder device 102 includes a position sensor 123 (FIG. 3) composed of a GPS (Global Positioning System) receiver and a motion sensor 124 (FIG. 3), as will be described later. The recorder device 102 detects the current position information (also referred to as "position monitoring information") of the target child wearing the school bag 1 using the position sensor 123, and stores the position monitoring information. Furthermore, the recorder device 102 detects information on the movement of the school bag 1 worn by the target child (this is referred to as "motion monitoring information") using the motion sensor 124, and stores the movement monitoring information.

FIG. 2 is a system configuration diagram of the monitoring system 20 in the first embodiment. The monitoring system 20 includes a school bag 1 worn by a target child, a server 2, a storage unit 3 connected to the server 2, and a mobile terminal 4, such as a general-purpose smartphone, owned by the target child's guardian. It consists of a network 5.

The monitoring device 100 for the school bag 1 acquires image monitoring information and corresponding audio monitoring information using the camera device 101 as monitoring information for the target child wearing the school bag 1. Furthermore, the monitoring device 100 uses the recorder device 102 to acquire position monitoring information and movement monitoring information as the monitoring information of the target child at the same timing as the acquisition timing of the image monitoring information and the audio monitoring information. Then, the monitoring device 100 of the school bag 1 transmits this monitoring information to the server 2 via the network 5 via a SIM (Subscriber Identifier Module).

The server 2 stores the monitoring information (image monitoring information, audio monitoring information, position monitoring information, and movement monitoring information) related to the target child transmitted from the school bag 1 in association with the monitoring information storage section 31 of the storage section 3. The server 2 analyzes the "safety of the target child" based on the "specific safety conditions" from the monitoring information stored in the monitoring information storage unit 31, and generates safety information based on the analysis result.

In the mobile terminal 4 owned by the guardian of the target child, the dedicated application for the monitoring system 20 is downloaded, installed, and activated. When an account, password, etc. unique to the user (guardian) are input in the dedicated application, the mobile terminal 4 is connected to the network 5.

Thereby, the server 2 can transmit the safety information regarding the target child to the child's guardian's mobile terminal 4 via the network 5, for example, by e-mail or the like. Furthermore, in the monitoring system 20, the mobile terminal 4 of the guardian of the target child can transmit a request to the server 2 to obtain monitoring information regarding the target child via the network 5. When the server 2 receives a request for obtaining monitoring information regarding the target child from the mobile terminal 4 via the network 5 , the server 2 transmits the monitoring information regarding the target child stored in the storage unit 3 to the mobile terminal 4 via the network 5 . Note that, as will be described later, transmission of the image monitoring information included in the monitoring information to the mobile terminal 4 may be restricted.

The monitoring system 20 monitors whether or not the target child wearing the school bag 1 is being bullied by surrounding children when going to and from school. Therefore, the monitoring system 20 analyzes the "vulnerability of bullying of the target child", such as whether the target child is a victim of bullying, as the "safety of the target child". . Then, the monitoring system 20 analyzes this "victimization of the target child by bullying" based on the "'bullying word information' stored in the databases 33 to 36" as the "specific safety conditions."

It is assumed that the school bag 1 is sold and used in various parts of Japan. Therefore, in the monitoring system 20, monitoring information is transmitted to the server 2 from each of the many school bags 1 used in various parts of Japan. The storage unit 3 includes a monitoring information storage unit 31 that stores monitoring information received from each school bag 1. Every time the server 2 receives the monitoring information from the school bag 1, the server 2 stores the monitoring information in the monitoring information storage section 31.

The monitoring information storage unit 31 associates image monitoring information and corresponding audio monitoring information with position monitoring information and movement monitoring information acquired at the same timing as the acquisition timing of the image monitoring information and audio monitoring information. and memorized. The monitoring information stored in the monitoring information storage unit 31 continues to be stored, for example, for 30 days, and is then deleted. Note that the period during which the monitoring information is stored in the monitoring information storage section 31 is not limited to this, and may be any period.

In this monitoring system 20, a storage unit 3 connected to the server 2 stores a bullying word national database (DB) 32, a bullying word northern Japan database 33, a bullying word eastern Japan database 34, a bullying word western Japan database 35, and a bullying word database 33. It has a southern Japan database 36 and a bullying word personal database 37. Here, ``bullying words'' refer to dirty words such as ``shit'', ``annoying'', and ``stupid'' that are hurtful when said by others.

The national bullying word database 32 is a database that manages bullying words uttered around children wearing school bags 1 in various parts of Japan. The server 2 adds additional information, which will be described later, to voice monitoring information corresponding to the bullying word (also referred to as "bullying word information") and stores it in the national bullying word database 32.

The bullying word information stored in this national bullying word database 32 is stored in any one of the bullying word northern Japan database 33, the bullying word east Japan database 34, the bullying word western Japan database 35, and the bullying word southern Japan database 36. The bullying word northern Japan database 33, bullying word eastern Japan database 34, bullying word western Japan database 35, and bullying word southern Japan database 36 are based on school bags 1 in "northern Japan," "eastern Japan," "western Japan," and "southern Japan," respectively. This is a database that manages bullying words used around children.

"Northern Japan" refers to Hokkaido and the Tohoku region; "Eastern Japan" refers to the Kanto-Koshin region, Hokuriku region and Tokai region; "Western Japan" refers to the Kinki region, Chugoku region and Shikoku region; "Southern Japan" refers to the Kinki region, Chugoku region and Shikoku region; refers to the Kyushu region and Okinawa region, but is not limited to this definition.

The server 2 stores the bullying word information stored in the national bullying word database 32 in local databases (Bullying word Northern Japan database 33, Bullying word East Japan database 34, Bullying word Western Japan database 35, The bullying word is stored in one of the Southern Japan Database 36). As a result, the nationwide bullying word information collected on the server 2 is classified into these regions. As a result, each of these regional databases 33 to 36 manages bullying words that are likely to be uttered in that region. That is, in the monitoring system 20, bullying words that are likely to be uttered in each region such as "Northern Japan," "Eastern Japan," "Western Japan," and "Southern Japan" can be managed on the server 2.

The personal bullying word database 37 is a database for managing bullying words uttered around each child wearing the school bag 1. The server 2 stores bullying word information in the bullying word personal database 37 for each ID that identifies the school bag 1.

For specific examples of the bullying word national database (DB) 32, bullying word northern Japan database 33, bullying word eastern Japan database 34, bullying word western Japan database 35, bullying word southern Japan database 36, and bullying word personal database 37, see Figure This will be described later using FIGS. 7 to 9.

FIG. 3 is a block diagram showing the functional configuration of the monitoring device 100. The monitoring device 100 transmits and receives data between the camera device 101 and the recorder device 102 via the cable 103 described above.

An image is captured and the image data is transmitted to the control unit 122 of the recorder device 102.

The audio acquisition unit 111 has a microphone, and uses this microphone to acquire audio surrounding the target child wearing the school bag 1 as "audio monitoring information". Then, the audio acquisition unit 111 transmits digital audio data to the control unit 122 of the recorder device 102 by A/D (analog/digital) conversion of the audio signal.

As will be described later, the speaker unit 112 is activated when the target child's position information (position monitoring information) is not within a pre-specified designated range, and when the target child's movement information (motion monitoring information) indicates that the movement of the school bag 1 is In any of the cases that indicate a sudden change, an alert is generated that sounds around the school bag 1. For example, the volume of this alert may become louder as time passes. Further, the alert may be stopped by operating an alert on/off switch (not shown). Note that the form of the alert is not limited to this.

As described above, the LED 101c lights up while the camera device 101 is operating. Thereby, the camera device 101 can make people around the target child recognize that the camera device 101 is operating.

Furthermore, in the monitoring device 100, the recorder device 102 includes a main body portion 121, a switch portion 127 and a battery 128 connected to the main body portion 121. The main body section 121 includes a control section 122, a position sensor 123, a motion sensor 124, a transmitting section 125, and a storage section 126.

In the main body section 121 , a control section 122 includes a CPU (Central Processing Unit) and the like, and controls the entire operation of the recorder device 102 . Furthermore, the storage unit 126 is composed of storage media such as ROM (Read Only Memory) and RAM (Random Access Memory). The control unit 122 stores the image data (image monitoring information) transmitted from the imaging unit 110 of the camera device 101 and the audio data (audio monitoring information) transmitted from the audio acquisition unit 111 of the camera device 101 in the storage unit 126. Remember.

As described above, the position sensor 123 is composed of a GPS receiver, detects the current position information (position monitoring information) of the target child wearing the school bag 1, and supplies it to the control unit 12. The control unit 122 stores the position monitoring information supplied from the position sensor 123 in the storage unit 126.

As described above, the motion sensor 124 detects movement information (movement monitoring information) of the school bag 1 worn by the target child and supplies it to the control unit 122. The control unit 122 stores the motion monitoring information supplied from the motion sensor 124 in the storage unit 126.

The transmitter 125 has the above-mentioned SIM. The control unit 122 reads the monitoring information (image monitoring information, audio monitoring information, position monitoring information, and movement monitoring information) stored in the storage unit 126 and supplies it to the transmitting unit 125. The transmitter 125 transmits the read monitoring information to the server 2 via the network 5 via the SIM.

The switch section 127 is constituted by a press-type switch that can be pressed with a child's fingertip. When pressed, the switch section 127 switches the operation of the monitoring device 100 (also referred to as the "monitoring function") between ON and OFF.

The battery 128 is a power source for the monitoring device 100, and can be charged from a charger using an AC adapter via a household AC power supply or from a commercially available primary battery.

By being equipped with the monitoring device 100 having such a configuration, the school bag 1 can acquire image monitoring information, audio monitoring information, position monitoring information, and movement monitoring information as monitoring information of the target child wearing the school bag 1, and The acquired monitoring information is transmitted to the server 2.

FIG. 4 is a sequence diagram for explaining the operation procedure of the monitoring system 20. The sequence diagram of FIG. 4 shows the operation processing of the school bag 1 worn by a child, the server 2, and the mobile terminal 4 owned by the child's guardian. In the monitoring system 20, the school bag 1, the server 2, and the mobile terminal 4 transmit and receive data via the network 5.

In step S1, the monitoring system 20 performs school bag control processing using the school bag 1. In this step S1, the school bag 1 acquires an image (image monitoring information) in substantially the same direction as the line of sight of the child wearing the school bag 1, as well as sounds around the child (audio monitoring information). In addition, the school bag 1 acquires current position information (position monitoring information) of the target child and information on movement of the school bag 1 (movement monitoring information). The school bag 1 then performs a process of transmitting the obtained monitoring information using the SIM of the transmitter 125.

In addition, in this step S1, the school bag 1 is operated when the child's position monitoring information is not within a pre-specified designated range, and when the child's movement monitoring information indicates that the movement of the school bag 1 has suddenly changed. An alert is generated in any of the following cases.

In step S2, the monitoring information is transmitted from the SIM of the transmitter 125 of the school bag 1 to the server 2 via the network 5.

In step S3, the monitoring system 20 performs bullying suppression processing by the server 2. In this step S3, if the server 2 determines that the voice monitoring information in the monitoring information received from the school bag 1 corresponds to a bullying word, it classifies the bullying word by region and by child (identification ID). Classify into. Then, the server 2 generates "bullying occurrence information" indicating that bullying has occurred as safety information, and determines the notification level thereof. Then, a process is performed to transmit safety information to the child's guardian's mobile terminal 4 according to the notification level.

In step S4, the safety information is transmitted from the server 2 to the mobile terminal 4 via the network 5.

In step S5, when a request is made to view an image of the child (target child) using the special application of the monitoring system 20 on the child's guardian's mobile terminal 4, the monitoring system 20 transmits the request from the mobile terminal 4 to the network 20. A request to obtain image monitoring information regarding the target child is sent to the server 2 via the server 2.

In step S6, the monitoring system 20 performs viewing authorization processing of the image monitoring information by the server 2. In this step S6, if the server 2 satisfies the restriction criteria described below, such as not transmitting safety information whose "notification level" is "warning (A) level" or higher to the mobile terminal 4, for example, Perform viewing restriction processing on image monitoring information.

In step S7, the monitoring system 20 transmits image monitoring information related to the viewing request from the server 2 to the mobile terminal 4 via the network 5. Note that in this step S7, the monitoring system 20 may transmit not only the image monitoring information but also the audio monitoring information corresponding to the image monitoring information to the mobile terminal 4.

In step S8, when the monitoring system 20 makes a request to obtain audio monitoring information regarding the target child using the dedicated application of the monitoring system 20 on the mobile terminal 4 of the guardian of the target child, the monitoring system 20 transmits information from the mobile terminal 4 to the server 2. A request to obtain voice monitoring information regarding the target child is transmitted to the server 2 via the network 5.

In step S9, the monitoring system 20 transmits the audio monitoring information related to the acquisition request from the server 2 via the network 5 to the mobile terminal 4.

In step S<b>10 , when a request is made to acquire location monitoring information regarding the target child using the dedicated application of the monitoring system 20 on the mobile terminal 4 of the guardian of the target child, the monitoring system 20 transmits information from the mobile terminal 4 via the network 5 . A request to obtain position monitoring information regarding the target child is sent to the server 2.

In step S11, the monitoring system 20 transmits the position monitoring information related to the acquisition request from the server 2 to the mobile terminal 4 via the network 5.

Although not shown in FIG. 4, it is possible to send a request to obtain movement monitoring information regarding the target child from the mobile terminal 4 to the server 2 via the network 5, and from the server 2 to the mobile terminal 4. The motion monitoring information may be transmitted.

In this way, in the monitoring system 20, the monitoring information related to the target child obtained from the school bag 1 worn by the target child and the safety information related to the target child based on the monitoring information are transmitted from the server 2 to the target child's guardian. is transmitted to the mobile terminal 4 of.

FIG. 5 is a flowchart for explaining the operation of the monitoring control process by the school bag 1 in step S1 in FIG.

In step S101, the school bag 1 determines whether the monitoring function by the monitoring device 100 is turned on (ON) by pressing the switch part 127, and if it is determined that the monitoring function is turned on (ON), Proceeding to step S102, if it is determined that it is OFF, the main monitoring control process is ended.

In step S102, the school bag 1 lights up the LED 101c provided on the camera device 101.

In step S103, the school bag 1 acquires image monitoring information regarding the target child. That is, the school bag 1 uses the imaging unit 110 of the camera device 101 to capture an image in substantially the same direction as the target child's line of sight, and stores the image data (image monitoring information) in the storage unit 126 of the recorder device 102. Remember.

In step S104, the school bag 1 acquires audio monitoring information regarding the target child. That is, the school bag 1 uses the audio acquisition unit 111 of the camera device 101 to record the sounds surrounding the target child, and stores the audio data (audio monitoring information) in the storage unit 126 as the audio monitoring information of the recorder device 102. .

In step S105, the school bag 1 acquires position monitoring information regarding the target child. That is, the school bag 1 uses the position sensor 123 of the recorder device 102 to detect the current position information (position monitoring information) of the target child wearing the school bag 1, and stores the detected position monitoring information in the recorder device 102. 126.

In step S106, the school bag 1 uses the control unit 122 of the recorder device 102 to determine whether the position monitoring information acquired in step S105 is within a specified range specified in advance. Examples of this "specified range specified in advance" include the school route from the home of the target child wearing the school bag 1 to the elementary school, the route from the elementary school to the cram school, the route from the cram school to the home, and the like. Parents can register these school routes, routes, etc. as specified ranges using a dedicated app for the monitoring system 20 on their own mobile terminals 4.

In this step S106, if the school bag 1 determines that the position monitoring information acquired in step S105 is within the specified range specified in advance (Yes in step S106), the process proceeds to step S108, and if the position monitoring information acquired in step S105 is not within the specified range. If it is determined (No in step S106), the process advances to step S107.

In step S107, the school bag 1 generates an alert from the speaker unit 112 of the camera device 101. In this case, since the school bag 1 does not exist within the pre-specified range, there is a risk that the child in question may have gone somewhere to play, or may have been taken away by someone, and may have fallen into a dangerous situation. . Therefore, it is possible to have the effect of urging people around the school bag 1 to monitor and be careful, and to warn and intimidate criminals and the like.

In step S108, the school bag 1 acquires movement monitoring information regarding the target child. That is, the school bag 1 uses the motion sensor 124 of the recorder device 102 to detect movement information and monitoring information of the school bag 1 worn by the target child, and stores the movement monitoring information in the storage unit 126 of the recorder device 102. .

In step S109, the school bag 1 determines whether the movement monitoring information acquired in step S108 is information indicating that the movement of the school bag 1 has suddenly changed, such as a sudden increase in acceleration, by the control unit 122 of the recorder device 102. to judge.

In this step S109, if the school bag 1 determines that the movement monitoring information acquired in step S108 is information indicating that the movement of the school bag 1 has suddenly changed (Yes in step S109), the school bag 1 proceeds to step S110, and If it is determined that the movement of No. 1 does not indicate a sudden change (No in step S109), the process advances to step S111.

In step S110, the school bag 1 generates an alert from the speaker unit 112 of the camera device 101. In this case, due to the sudden change in the movement of the school bag 1, there is a risk that the target child may be in a dangerous situation, such as colliding with a car or the like, suddenly running away, or receiving violence from someone. Therefore, similarly to step S107, the generation of the alert can exert effects such as monitoring, warning, warning, and intimidation on those around the school bag 1.

Note that the school bag 1 is not limited to the case where the motion sensor 124 detects such a sudden change in the movement of the school bag 1, but also the case where no change in the movement of the school bag 1 is detected for a long period of time during the commuting time. An alert may also be generated. For example, for the school bag 1, there is a predetermined period of time in which no change in the movement of the school bag 1 is detected during the morning school hours (for example, 7:00 to 9:00) and the evening school leaving hours (for example, 15:00 to 18:00). (for example, one hour) or more, an alert is generated from the speaker unit 112. In this case, the school bag 1 may have been left unattended for a long time, and there is a possibility that the target child may have been taken away while the school bag 1 was left there. Therefore, in this case as well, effects such as monitoring, caution, warning, and intimidation can be exerted.

In step S111, the school bag 1 performs a process of transmitting the monitoring information (image monitoring information, audio monitoring information, position monitoring information, movement monitoring information) stored in the storage unit 126 of the recorder device 102 using the SIM of the transmitting unit 125. . These monitoring information is transmitted from the transmitter 125 of the school bag 1 to the server 2 via the network 5. The school bag 1 then ends the main monitoring control process.

FIG. 6 is a flowchart for explaining the operation of the bullying suppression process performed by the server 2 in step S3 of FIG.

In step S301, the server 2 stores the monitoring information (image monitoring information, audio monitoring information, position monitoring information, and movement monitoring information) received from the school bag 1 via the network 5 in the monitoring information storage unit 31.

In step S302, the server 2 determines whether the audio of the audio monitoring information in the monitoring information stored in the monitoring information storage unit 31 corresponds to a bullying word, and if it is determined that the audio corresponds to a bullying word, (Yes in step S302) The process advances to step S303, and if it is determined that the word does not correspond to a bullying word (No in step S302), the present bullying suppression process ends.

In step S303, the server 2 adds "local information" and "date and time information" as additional information to the audio monitoring information (bullying word information) determined to correspond to the bullying word in step S302, and adds "local information" and "date and time information" to the bullying word national database (bullying word information). DB) 32.

"Local information" is the region where the location indicated by the location monitoring information associated with the audio monitoring information of the bullying word exists, and is one of "Northern Japan," "Eastern Japan," "Western Japan," or "Southern Japan." This is information indicating the region of . "Date and time information" is information indicating the date and time when the audio monitoring information of the bullying word was recorded by the school bag 1. A specific example of storing bullying word information in the national bullying word database 32 will be described later using FIG. 7.

In step S304, the server 2 classifies the bullying word information stored in the national bullying word database 32 by region indicated by the local information added to the bullying word information.

That is, the server 2 reads the bullying word information stored in the national bullying word database 32, and selects "Northern Japan," "Eastern Japan," "Western Japan," and "Southern Japan" indicated by the local information added to the bullying word information. It is stored in a database corresponding to any region (Bullying word Northern Japan database 33, Bullying word East Japan database 34, Bullying word Western Japan database 35, or Bullying word Southern Japan database 36).

For example, the bullying word information "Uzai" with "Eastern Japan" added as local information is stored in the bullying word East Japan database 34, and the bullying word information "Aho" with "Western Japan" added as local information is stored in the bullying word East Japan database 34. It is stored in the database 35.

In this way, the bullying word northern Japan database 33, the bullying word eastern Japan database 34, the bullying word western Japan database 35, and the bullying word southern Japan database 36 each store bullying word information acquired in the region. In this way, "bullying word information" as the above-mentioned "specific safety conditions" is extracted for each region.

The server 2 stores bullying word information stored in each of the databases 33 to 36 for each region of "Northern Japan," "Eastern Japan," "Western Japan," and "Southern Japan" from the audio acquired by the school bag 1. If it is determined that the school bag falls under the bullying word, safety information indicating that bullying has occurred is sent to the mobile terminal 4 of the guardian of the child wearing the school bag 1. A specific example of storing bullying word information in the bullying word East Japan database 34, which is an example of a local database, will be described later using FIG.

In step S305, the server 2 identifies the audio monitoring information (bullying word information) corresponding to the bullying word in the monitoring information stored in the monitoring information storage unit 31, and the school bag 1 in which the audio of the bullying word was recorded. Classify by ID (that is, identify the child). That is, the server 2 adds "date and time information", "location information" (location monitoring information), "volume index", "word danger index", as additional information to the bullying word information for each identification ID. The "number of occurrences of bullying words/day" and the "bullying occurrence index" are associated and stored in the bullying word personal database 37. Note that a specific example of storing bullying word information in the bullying word personal database 37 will be described later using FIG. 9.

In step S306, the server 2 provides "bullying occurrence information" indicating that bullying has occurred to the target child as safety information for the child (target child) wearing the school bag 1 for which the voice monitoring information has been received. ” is generated.

In step S307, the server 2 determines a notification level, which is an index of the importance of notification of the safety information generated in step S306, using a safety information notification mode determination table to be described later.

In step S308, the server 2 transmits the safety information to the mobile terminal 4 owned by the guardian of the target child in a notification manner according to the notification level determined in step S307, based on a safety information notification manner determination table to be described later. to notify. For example, the server 2 adds notification mode information indicating the determined notification mode to the safety information so that the safety information is notified using the dedicated application of the monitoring system 20 on the mobile terminal 4 in the determined notification mode. It is transmitted via the network 5 to the mobile terminal 4 owned by the guardian of the target child. For example, the server 2 notifies the mobile terminal 4 of the safety information by e-mail or the like according to the determined notification mode, as will be described later.

However, in this step S308, if the notification level determined in step S307 is a "safety (C) level" to be described later, the server 2 does not transmit the safety information in the first place.

After the process of step S308, the server 2 ends the bullying suppression process.

Note that a specific example of determining the notification mode of safety information using this safety information notification mode determination table will be described later using FIG. 11.

FIG. 7 is a diagram showing a specific example in which bullying word information is stored in the national bullying word database 32. If voice monitoring information for the bullying word "annoying" is recorded by the school bag 1 in Tokyo at 16:05 on June 1, 2016, as shown in FIG. 7(a), in the national bullying word database 32, "Annoying" is stored as "bullying word information," "Eastern Japan" is stored as "regional information," and "2016/6/1, 16:05" is stored as "date and time information."

Each time such bullying word information is recorded by the school bag 1, the "bullying word information" is stored in association with local information and date/time information. FIG. 7(b) shows an example in which the bullying word "annoying" is uttered four times in a row to a certain child.

In this way, as shown in FIG. 7(c), the bullying word information acquired from the school bags 1 all over the country continues to be stored in the bullying word national database 32. In addition, in the bullying word national database 32, the bullying word information continues to be stored for a predetermined period (for example, 30 days), and is then deleted.

FIG. 8 is a diagram showing a specific example in which bullying word information is stored in the bullying word East Japan database 34. The bullying word East Japan database 34 stores the acquired bullying word information and the number of occurrences of the bullying word in East Japan (total number of occurrences of the bullying word in East Japan), which is updated every time bullying word information is acquired in East Japan. , and the ranking according to the number of occurrences of bullying words in East Japan as a whole are stored in association with each other. In the bullying word East Japan database 34, the higher the ranking is set for bullying word information that has a greater number of occurrences throughout East Japan.

For example, in a state where the server 2 has not acquired bullying word information from any of the school bags 1 in East Japan, as shown in FIG. 8(a), the default information is "Shine", "Kimoi", " Bullying word information indicating bullying words such as "annoying", "stupid", and "stupid" is stored. After that, as shown in FIG. 8(b), each time these pieces of bullying word information are recorded, the number of occurrences of that bullying word in East Japan is updated for each piece of bullying word information, and the number of occurrences of that bullying word in East Japan is updated accordingly. The ranking will be set. In Figure 8(b), the number of occurrences of bullying words in East Japan for the first place "baka" and the second place "shine", the third place "kimoi" and the fourth place "annoying", is compared with the number of occurrences for the fifth place The number of occurrences of the bullying word "stupid" in East Japan has decreased dramatically.

If the server 2 determines that the number of occurrences of the 5th place bullying word "stupid" in East Japan does not exceed a certain number of times (for example, 100 times) after a certain period of time (for example, 10 days) has passed, then As shown in c), the next time a new type of bullying word information "Kinnai" is stored, the bullying word information "Kinnai" is stored instead of the bullying word information "Dumb".

Similarly to the bullying word East Japan database 34, bullying word information acquired in the region is also stored in the Bullying Word North Japan database 33, Bullying Word West Japan database 35, and Bullying Word South Japan database 36.

FIG. 9 is a diagram showing a specific example in which bullying word information is stored in the bullying word personal database 37. In the bullying word personal database 37, for each identification ID for identifying the school bag 1 (that is, child), the bullying word information acquired by the school bag 1 includes "date and time information" and "location information" (position monitoring information). ), "volume index", "word danger index", "number of occurrences of bullying words/day", and "bullying occurrence index" are stored in association with each other.

Here, the "volume index" is an index indicating the volume of the audio of the bullying word information, and is classified into five levels from 1, which is the minimum volume, to 5, which is the maximum volume. The server 2 stores any one of the volume indexes from 1 to 5 in the bullying word personal database 37 as the volume index related to the audio of the bullying word from the audio monitoring information transmitted from the school bag 1 to the server 2.

The "word danger index" is an index indicating the danger of the meaning of a bullying word. Server 2 uses bullying words uttered around the target child wearing school bag 1, such as "shine", "korosu", and "hitting", which are likely to cause physical harm to the target child. If the word is a dangerous bullying word that is likely to lead to serious bullying, a value of 5 is determined as the "word danger index."

In addition, if the bullying word is one that has a low possibility of causing physical harm to the target child, such as "annoying" or "disgusting," but has the potential to develop into serious bullying, the word "dangerous word" 4 is determined as the index.

For example, Server 2 may use bullying words uttered around the target child such as "stupid," "idiot," or "idiot," which are less likely to cause physical harm to the target child and are not serious. If the word is a bullying word, 2 is determined as the "word danger index". The server 2 determines the "word danger index" of the bullying word in the voice monitoring information transmitted from the school bag 1 to the server 2, and stores it in the bullying word personal database 37.

Moreover, "number of times of occurrence of bullying words/day" means the number of times that the server 2 currently acquires bullying word information from the school bag 1 identified by the identification ID on that day. The server 2 stores the current "number of occurrences of bullying words/day" in the bullying word personal database 37.

Further, the "bullying occurrence index" is an index determined in accordance with the current "number of occurrences of bullying words/day" associated with the identification ID stored in the bullying word personal database 37. The server 2 determines the "bullying occurrence index" based on the current "number of occurrences of bullying words/day" associated with the identification ID stored in the personal bullying word database 37.

For example, server 2 determines 2 as the "bullying occurrence index" if the current "number of occurrences of bullying words/day" is 1 to 5 times, and determines 2 as the "bullying occurrence index" if it is 6 to 10 times. 3 is determined, if it is 11 to 15 times, 4 is determined as the "bullying occurrence index", and if it is 16 times or more, 5 is determined as the "bullying occurrence index". Then, the server 2 stores the determined "bullying occurrence index" in the bullying word personal database 37.

In the bullying word personal database 37 of FIG. 9, on June 1, 2016, the server 2 received the bullying word information "annoying" four times in a row from the school bag 1 with the identification ID "2698" in Tokyo. After that, a state is shown in which the bullying word information "Shine" is received once.

As shown in FIG. 9, the bullying word personal database 37 includes information as of June 1, 2016 about the child wearing the school bag 1 identified by the identification ID "2698", which is the bullying word information "annoying". ”, the date and time information “2016/6/1, 16:05” indicating the date and time of the recording, and the location information of the school bag 1 with the identification ID “2698” at the time of the recording “Tokyo 〇 〇 Ward...'', the audio volume index of the bullying word information 5, the word danger index 4, the number of bullying word occurrences/day 5, and the bullying occurrence index 2 are associated. It is being In addition, this child's information for this day includes the bullying word information "Shine", the date and time information "2016/6/1, 16:52", and the location information "Tokyo 〇〇 Ward... ", its volume index of 5, word danger index of 5, number of occurrences/day of bullying words of 5, and bullying occurrence index of 2 are associated.

FIG. 10 is a flowchart for explaining the operation of the viewing authorization process performed by the server 2 in step S6 of FIG. FIG. 10(a) is a flowchart for explaining viewing authorization processing (Example 1) which is an example of this viewing authorization processing, and FIG. 10(b) is a flowchart for explaining viewing authorization processing (example 1) which is an example of this viewing authorization processing. It is a flowchart for explaining processing (Example 2).

As described above, this viewing authorization process by the server 2 is a process that is performed in response to a request to acquire image monitoring information from the guardian's mobile terminal 4 to the server 2 in step S5 of FIG.

In the viewing authorization process (Example 1) shown in FIG. 10A, in step S601, the server 2 informs the mobile terminal 4 that has made the image monitoring information acquisition request that it currently owns the mobile terminal 4 on that day. Determine whether or not the guardian has sent any safety information regarding the child (target child).

If the server 2 determines that any safety information has been sent to the mobile terminal 4 (Yes in step S601), the process proceeds to step S602, and the server 2 transmits any safety information to the mobile terminal 4. If it is determined that the data has not been transmitted (No in step S601), the process advances to step S603.

In step S602, the server 2 determines that the "notification level" of the safety information determined to have been transmitted in step S601 is equal to or higher than the "warning (A) level" ("warning (A) level" or "emergency (S) level"), which will be described later. ”). If the server 2 determines that the "notification level" of this safety information is equal to or higher than the "warning (A) level" (Yes in step S602), the server 2 proceeds to step S604 and sets the "warning (A) level" to the "warning (A) level". If it is determined that it is less than (“cognitive (B) level”) (No in step S602), the process advances to step S603.

In step S603, the server 2 determines that the image monitoring information satisfies the restriction criteria for restricting the transmission of the image monitoring information to the mobile terminal 4, and performs viewing restriction processing on the image monitoring information to make the image invisible or difficult to see. In this step S603, the server 2 reads the image monitoring information acquired when the image monitoring information acquisition request is made from the monitoring information storage unit 31, and performs mosaic processing on the image data of the image monitoring information as a viewing restriction process. , performs image processing such as blurring and filling.

In step S604, the server 2 informs the guardian of the image because the process following step S602 is after the "warning (A) level" or "emergency (S) level" safety information has been sent. Since there is a strong need to recognize the content, a process is performed in which image monitoring information consisting of image data that is not subjected to the above-mentioned viewing restriction process is sent via the network 5 to the mobile terminal 4 of the parent who has requested to view the image monitoring information. conduct. Furthermore, in this process, the server 2 may transmit to the mobile terminal 4 audio monitoring information corresponding to this image monitoring information along with image monitoring information consisting of image data that is not subjected to viewing restriction processing.

In addition, in step S604, the server 2 determines whether the safety information has not been transmitted to the mobile terminal 4 or after the safety information of "cognitive (B) level" has been transmitted, as a process subsequent to step S603. Therefore, there is little need for parents to recognize the content of the image, so parents who have made a request to view the image monitoring information via the network 5, which consists of image data that has been subjected to the above-mentioned viewing restriction processing, The process of transmitting data to the mobile terminal 4 is performed. Further, in this process, the server 2 may transmit to the mobile terminal 4 audio monitoring information corresponding to this image monitoring information along with image monitoring information consisting of image data subjected to viewing restriction processing.

Alternatively, in step S604, the server 2 determines whether the safety information has not been transmitted to the mobile terminal 4 or after the "cognitive (B) level" safety information has been transmitted, as a process subsequent to step S603. Therefore, since there is little need for the guardian to recognize the content of the image, the image monitoring information may not be transmitted to the mobile terminal 4 in the first place. In this case, the server 2 may transmit only the voice monitoring information to the mobile terminal 4.

In step S604, the server 2 performs the above-mentioned process following step S603, so that the guardian of the target child can determine whether the safety information has not been notified or whether the safety information is at the "cognitive (B) level". In a situation where the target child has not encountered serious bullying, such as after being notified, the parent or guardian can be prevented from needlessly viewing the images.

After performing the process of step S604, the server 2 ends the main viewing authorization process (Example 1).

In the viewing authorization process (Example 2) shown in FIG. 10(b), in step S611, the server 2 determines that the position monitoring information (position information) stored in the monitoring information storage unit 31 is within a specified range specified in advance. Determine whether or not.

If the server 2 determines that the location monitoring information (position information) is within the pre-designated range (Yes in step S611), the server 2 proceeds to step S613, and the location monitoring information (location information) is , if it is determined that it is not within the specified range specified in advance (No in step S611), the process advances to step S612.

In step S612, the server 2 determines that the image monitoring information satisfies the restriction criteria for restricting the transmission of the image monitoring information to the mobile terminal 4, and performs the same viewing restriction process as in step S603 described above on the image monitoring information.

In step S613, the server 2 performs the same image monitoring information transmission process as in step S604 described above. That is, in step S613, the process following step S611 is the same as the process following step S602 in step S604 described above, and the process subsequent to step S612 is the process subsequent to step S603 in step S604 described above. Perform the same processing as . After performing the process of step S613, the server 2 ends the main viewing authorization process (Example 2).

FIG. 11 is a diagram showing a specific example of the safety information notification mode determination table used in step S307 and step S308 of FIG. This safety information notification mode determination table 39 is stored in a partial area of the storage unit 3 included in the server 2.

As shown in FIG. 11, the safety information notification mode determination table 39 includes "safety (C) level" and "cognitive (B) level" as "notification levels" that are indicators of the importance of notification of safety information. ”, “warning (A) level”, and “emergency level (S)” are stored. The importance of notifying parents of safety information increases as the level increases to "Safety (C) Level," "Awareness (B) Level," "Warning (A) Level," and "Emergency Level (S)." , the manner in which parents are notified will become easier to recognize.

When determining this notification level, the server 2 uses the "volume index", "word danger index", and "bullying word index" associated with the identification ID of the target child stored in the bullying word personal database 37 in FIG. The "incidence index" is multiplied to calculate the integrated value, and the "notification level" when notifying the safety information related to the target child is determined according to the integrated value.

For example, if the integrated value obtained by multiplying the "volume index," "word danger index," and "bullying occurrence index" is 30 or less, the server 2 determines the "safety (C) level" as the "notification level." , if it is 31 to 60, the "cognitive (B) level" is determined as the "notification level", if it is 61 to 90, the "warning (A) level" is determined as the "notification level", and if it is 91 or higher, the "warning (A) level" is determined as the "notification level". The "emergency (S) level" is determined as the "notification level".

Note that the method for determining the notification level is not limited to this method. For example, the manner in which the bullying word is uttered and the context of the conversation before and after the bullying word is generated may also be defined as indices, and the integrated value may be calculated using these indices.

When the server 2 determines the "safety (C) level" as the "notification level", the server 2 determines "not to notify" the safety information to the guardian's mobile terminal 4. As a result, when the target child is in a safe condition, the parent of the target child is not needlessly notified by e-mail, so it is possible to prevent the guardian from feeling bothered.

In addition, when the server 2 determines the "awareness (B) level" as the "notification level", the server 2 "notifies" the safety information to the parent's mobile terminal 4 by e-mail, and lights up the LED of the mobile terminal 4. decide to do so. Alternatively, in this case, the server 2 may decide only to "notify the guardian's mobile terminal 4 of the safety information by email."

Furthermore, when the server 2 determines the "warning (A) level" as the "notification level", the server 2 "notifies" the safety information to the parent's mobile terminal 4 by e-mail, and also sounds an alarm on the mobile terminal 4. decide.

In addition, when the server 2 determines the "emergency (S) level" as the "notification level", the server 2 notifies the parent's mobile terminal 4 of the safety information by email, and also sends an alarm on the mobile terminal 4. It is decided to make a sound and also to light up the LED of the mobile terminal 4.

The server 2 transmits the safety information to the mobile terminal 4 in the notification mode determined in this way. Note that the example of the notification mode of safety information is not limited to this.

FIG. 12 is a diagram showing a display example of the screen of the mobile terminal 4. As shown in FIG. FIG. 12(a) shows an example of the initial screen of the dedicated application of the monitoring system 20, and FIG. 12(b) shows an example of the screen of an email related to safety information sent from the server 2 in the monitoring system 20. It shows.

When the "Safe Watching Service", which is a dedicated application for the monitoring system 20, is started on the mobile terminal 4, the "Safe Watching Service" is displayed on the display section 401 of the mobile terminal 4, as shown in FIG. 12(a). An initial screen 402 is displayed. The initial screen 402 displays a clickable display area 403 for "viewing images," a display area 404 for "acquiring audio," and a display area 405 for "acquiring location information."

When the parent or guardian of the target child clicks on the display area 403 for "view images", a request to obtain image monitoring information regarding the target child is transmitted from the mobile terminal 4 to the server 2 via the network 5. Then, the image monitoring information related to the acquisition request is transmitted from the server 2 to the mobile terminal 4 via the network 5, so that the image is displayed on the display unit 401 of the mobile terminal 4.

As mentioned above, if the server 2 has not sent safety information to the mobile terminal 4 or has sent safety information at the "cognitive (B) level", the parent or guardian of the target child Even if the user clicks on the display area 403 for “view image”, will the image that has been subjected to viewing control processing be displayed as image monitoring information on the display unit 401 of the mobile terminal 4 of the parent of the target child? , or such an image itself is not displayed.

In addition, when the guardian of the target child clicks on the display area 404 for "audio acquisition" to request the acquisition of voice monitoring information for the target child, the mobile terminal 4 sends the information to the server 2 via the network 5. A request to obtain voice monitoring information regarding the target child is sent. Then, the voice monitoring information related to the acquisition request is transmitted from the server 2 to the mobile terminal 4 via the network 5, and the voice is output from the speaker of the mobile terminal 4.

In addition, when the guardian of the target child clicks on the display area 405 for "Obtain location information" to request the acquisition of location monitoring information for the target child, the mobile terminal 4 sends the request to the server 2 via the network 5. A request to obtain location monitoring information regarding the target child is sent to. Then, by transmitting the location monitoring information related to the acquisition request from the server 2 to the mobile terminal 4 via the network 5, a map clearly indicating the current location of the target child is displayed on the display unit 401 of the mobile terminal 4. An image and a character image of the prefecture, city, ward, town, village, district, street address, etc. of the location are displayed.

In addition, in the monitoring system 20, the server 2 notifies the mobile terminal 4 of "bullying occurrence information" as safety information by e-mail on the e-mail screen 410 as shown in FIG. 12(b), for example. In the e-mail screen 410 shown in FIG. 12(b), for example, after a sentence such as "We would like to notify you of the following safety information from 'Anshin Monitoring Service'", "Safety information: Bullying has occurred", "Date and time: 2016/06/23" and "Time 15:20" are displayed as the date and time information when the bullying word information was recorded. Then, "Bullying word 'Shine'" indicating that the bullying word "Shine" has occurred, and "Warning (A)" indicating that the notification level is "Warning (A) level" are displayed.

Since the notification level of the safety information is the "warning (A) level" as described above, the mobile terminal 4 causes an alarm to sound when such a mail is displayed.

In the first embodiment, the monitoring device 100 is configured by connecting the camera device 101 and the recorder device 102 via the cable 103, but the configuration of the monitoring device is not limited to this.

A second embodiment of the present invention (hereinafter referred to as "second embodiment") will be described in detail using FIGS. 13 and 14.

FIG. 13 is a perspective view of a school bag 1A according to the second embodiment. In this second embodiment, the same components as those described in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

The monitoring device 200 included in the school bag 1A has a camera-equipped recorder device 201, which is a recorder device having the function of a camera device, and a mobile terminal 230 owned by the child wearing the school bag 1A, through a cable 203 such as a USB cable. connected via. This mobile terminal 230 is, for example, a general-purpose smartphone, and is housed in a housing case 14A formed in the school bag 1A. In addition to the imaging lens 101b and the LED 101c, the rectangular parallelepiped housing 201a of the camera-equipped recorder device 201 is provided with a switch section 227 configured by a press-type switch that can be pressed with a child's fingertip.

The monitoring device 200 in the second embodiment transmits image monitoring information and audio monitoring information acquired by such a camera-equipped recorder device 201 to the mobile terminal 230 via the cable 203.

Furthermore, the mobile terminal 230 is equipped with a function corresponding to the position sensor 123 described above and a function corresponding to the motion sensor 124 described above. Thereby, the mobile terminal 230 can acquire position monitoring information and movement monitoring information regarding the target child using these functions.

Therefore, in the monitoring device 200, the mobile terminal 230 transmits image monitoring information, audio monitoring information, position monitoring information, and movement monitoring information to the server 2 via the network 5 via the SIM installed therein.

For this reason, in the monitoring device 200, the camera-equipped recorder device 201 does not include any of the configurations corresponding to the position sensor 123 described above and the configuration equivalent to the motion sensor 124 described above. Further, the camera-equipped recorder device 201 does not have a communication function such as the above-mentioned SIM for transmitting data to the server 2 via the network 5. From this point of view, the monitoring device 200 can reduce its manufacturing cost more than the above-described monitoring device 100.

FIG. 14 is a block diagram showing the functional configuration of the monitoring device 200 in the second embodiment. The monitoring device 200 transmits and receives data between the camera-equipped recorder device 201 and the mobile terminal 230 via the cable 203 described above.

In the monitoring device 200, the camera-equipped recorder device 201 includes a main body portion 211, a switch portion 127 connected to the main body portion 211, and a battery 128. The main body section 211 includes an imaging section 110 having an imaging lens 101b, an audio acquisition section 111, a speaker section 112, and an LED 101c, which have the same configuration as the camera device 101 described above. Further, the main body section 211 includes a control section 122, a transmitting section 225, and a storage section 126.

In the main body section 211, a control section 122 controls the entire operation of the camera-equipped recorder device 201. Further, the control unit 122 stores the image data (image monitoring information) supplied from the imaging unit 110 and the audio data (audio monitoring information) transmitted from the audio acquisition unit 111 in the storage unit 126. Then, the control unit 122 supplies the image monitoring information and audio monitoring information stored in the storage unit 126 to the transmitting unit 225.

The transmitter 225 transmits image monitoring information and audio monitoring information to the mobile terminal 230 via the cable 203 such as a USB cable. Note that the transmitter 225 may transmit the image monitoring information and audio monitoring information to the mobile terminal 230 by wireless communication instead of via such a cable 203.

The mobile terminal 230 sends the image monitoring information and voice monitoring information received from the transmitter 225 and the position monitoring information and movement monitoring information acquired by itself to the server 2 via the network 5 via the SIM installed in the mobile terminal 230. Send to.

In the embodiments described above (first and second embodiments), an example was described in which the server 2 transmits safety information to the mobile terminal 4 every time it receives monitoring information from the school bag 1, but the present invention is limited to such an example. Not done. For example, in the monitoring system 20, the server 2 may transmit safety information to the mobile terminal 4 at a specific time (for example, 18:00) within the day. Thereby, the monitoring system 20 can prevent the trouble caused by frequent notification of safety information to the guardian's mobile terminal 4.

Furthermore, in the above-described embodiment, the "safety of the target child" is defined as "the victimization of the target child" and the "specific safety condition" is defined as "'bullying word information' stored in the databases 33 to 36". Although an example has been described in which "bullying occurrence information" indicating that bullying has occurred is generated as safety information, the present invention is not limited to such an example. For example, in the monitoring system 20, the "safety of the target child" is set as "the likelihood of the target child encountering a suspicious person, etc.", the "specific safety condition" is set as "the face image stored in the suspicious person database", and the safety As information, "suspicious person encounter information" indicating that a suspicious person or the like was encountered may be generated.

In this case, the server 2 stores facial image data of suspects, suspicious persons, etc. whose information is provided by the police, government offices, etc. in the suspicious person database as suspicious person data. Then, if the image monitoring information received from the school bag 1 worn by the target child includes a face image stored in the suspicious person database, the server 2 generates "suspicious person encounter information" as safety information. may be sent to the mobile terminal 4 of the guardian of the target child.

Further, in the monitoring system 20 of the above-described embodiment, the mobile terminal 4 displays information on the viewing history on the dedicated application of the monitoring system 20 every time the guardian views the image related to the viewing request. Good too. Further, the server 2 may store this browsing history information. Thereby, the monitoring system 20 can make the guardian who owns the mobile terminal 4 aware of the number of times, frequency, etc. of image viewing.
