DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] [Embodiment 1] The security system and security method according to the first embodiment will be described in detail below with reference to the drawings.

[0025] <Overview of security system according to embodiment 1> 1 is an explanatory diagram for explaining an overview of the security system according to the embodiment 1. In the security system according to the embodiment 1, when the security mode is on and a detection signal is received from a sensor that detects the opening of a window or the like in a house, a predetermined alarm is issued.

[0026] The on / off control of the security mode can be performed by operating the controller, or by using a mobile terminal. In the present embodiment 1, a security system is described in which the on / off control of the security mode is performed by using an NFC tag having an NFC (Near Field Communication) function, which is a short-distance wireless communication technology, and a mobile terminal.

[0027] As shown in FIG. 1(a), when controlling the security mode to be turned on, the mobile terminal 30 reads the security tag ID for turning on the security mode from the NFC tag 10 for turning on the security mode attached to the inside of the entrance door (S1), and transmits this security tag ID and a user ID indicating the operator of the mobile terminal to the server 40 (S2).

[0028] The server 40 uses the received security tag ID and user ID to identify the type of control (security mode on) and the controller 50 to be controlled (S3). Then, when the server 40 transmits a security mode on signal to the controller 50 (S4), the controller 50 controls the security mode to on (S5).

[0029] Also, as shown in FIG. 1(b), when controlling the security mode to be turned off, the mobile terminal 30 reads the security tag ID for turning off the security mode from the NFC tag 20 for turning off the security mode attached to the outside of the entrance door (S6), and transmits this security tag ID and the user ID to the server 40 (S7).

[0030] The server 40 uses the received security tag ID and user ID to identify the type of control (security mode off) and the controller 50 to be controlled (S8). Then, when the server 40 transmits a security mode off signal to this controller 50 (S9), the controller 50 controls the security mode to be off (S10).

[0031] In this way, the security system of this embodiment 1 is configured to read the security tag ID from the NFC tag for turning the security mode on or the NFC tag for turning the security mode off (collectively referred to as "security NFC tags" below) and use the read security tag ID to control the security mode on / off, thereby allowing the security mode to be set efficiently and accurately.

[0032] <System configuration according to the first embodiment> Next, a description will be given of the system configuration of the security system according to the present embodiment 1. Fig. 2 is a diagram showing the system configuration of the security system according to the present embodiment 1. As shown in Fig. 2, a mobile terminal 30, a server 40, and a controller 50 are connected to each other so as to be able to communicate with each other via the Internet.

[0033] The mobile terminal 30 is a terminal device such as a smartphone carried by a user of the security system. When the mobile terminal 30 receives settings for login authentication and execution confirmation, the mobile terminal 30 transmits the received settings and the user ID to the server 40.

[0034] Furthermore, when the mobile terminal 30 reads the security tag ID from the security NFC tag, the mobile terminal 30 transmits the security tag ID and the user ID to the server 40.

[0035] Furthermore, the mobile terminal 30 displays a login screen when it receives a login screen display instruction from the server 40. Then, it authenticates the operator using the accepted user ID and password, and if the authentication is successful, that is, if it is confirmed that the operator is a legitimate user, it transmits a user authentication notification to the server 40.

[0036] Furthermore, the mobile terminal 30 displays an execution confirmation screen upon receiving an execution confirmation screen display instruction from the server 40. Then, upon accepting an execution confirmation operation, the mobile terminal 30 transmits an execution confirmation notification to the server 40.

[0037] Furthermore, when the mobile terminal 30 receives a security mode ON completion notification from the server 40, it displays that the security mode of the controller 50 has become ON, and when it receives a security mode OFF completion notification, it displays that the security mode of the controller 50 has become OFF. When the mobile terminal 30 receives a locking abnormality notification from the server 40, it displays a locking abnormality display screen.

[0038] The server 40 is installed in a security center or the like, and is a device that transmits and receives security mode on / off signals and the like to and from the mobile terminal 30 and the controller 50. When the server 40 receives settings for login authentication and execution confirmation and a user ID from the mobile terminal 30, it stores the received data in confirmation setting data.

[0039] Furthermore, when the server 40 receives the user ID and security tag ID from the mobile terminal 30, it uses the received IDs to identify the type of control and the controller ID indicating the controller to be controlled.

[0040] In addition, if the login authentication of the confirmation setting data for the user ID received from the mobile terminal 30 is ``yes'', the server 40 sends a login screen display instruction to the mobile terminal 30, and if the execution confirmation of the confirmation setting data for the received user ID is ``yes'', the server 40 sends an execution confirmation screen display instruction to the mobile terminal 30.

[0041] Furthermore, the server 40 performs the following process using the identified control type and controller ID: If the control type is "security mode on", it transmits a security mode on signal to the controller 50 corresponding to the identified controller ID, and if the control type is "security mode off", it transmits a security mode off signal to the controller 50 corresponding to the identified controller ID.

[0042] Furthermore, when the server 40 receives a security mode on completion notification, a security mode off completion notification, or a lock abnormality notification from the controller 50, the server 40 transmits the received notification to the mobile terminal 30.

[0043] The controller 50 is a device installed in the house that controls the on / off of the security mode. When the controller 50 receives a security mode on signal from the server 40, it checks the door lock status based on the reception status of the detection signal from the sensor. If the controller 50 does not receive a detection signal from the sensor at this time, it turns the security mode on, completes the control of the security mode, and transmits a security mode on completion notice to the server 40. Note that if the controller 50 receives a detection signal from the sensor when it checks the door lock status, it transmits a door lock abnormality notice to the server 40 without controlling the security mode to on.

[0044] Furthermore, upon receiving a security mode off signal from the server 40, the controller 50 turns off the security mode and transmits a security mode off completion notification to the server 40.

[0045] <Configuration of mobile terminal 30> Next, a description will be given of the configuration of the mobile terminal 30. Fig. 3 is a functional block diagram showing the configuration of the mobile terminal 30 shown in Fig. 2. As shown in Fig. 3, the mobile terminal 30 has a display operation unit 31, a reading unit 32, a communication unit 33, a storage unit 35, and a control unit 36.

[0046] The display operation unit 31 is an input / output device such as a touch panel display. The reading unit 32 is an input device that reads data using NFC. The communication unit 33 is an interface unit for data communication with the Internet.

[0047] The storage unit 35 is a storage device formed of a non-volatile memory or a hard disk drive, and stores login data 35a. The login data 35a is data used for authenticating an operator when controlling the security mode on / off.

[0048] The control unit 36 ​​is a control unit that performs overall control of the mobile terminal 30, and has a setting management unit 36a, a reading control unit 36b, an ID notification unit 36c, a login control unit 36d, an execution confirmation unit 36e, and a display control unit 36f. In practice, these programs are loaded into a CPU (Central Processing Unit) and executed, causing the setting management unit 36a, the reading control unit 36b, the ID notification unit 36c, the login control unit 36d, the execution confirmation unit 36e, and the display control unit 36f to execute the processes corresponding thereto.

[0049] The setting management unit 36a is a processing unit that manages settings for login authentication and execution confirmation. When the setting management unit 36a receives settings for login authentication and execution confirmation from the display operation unit 31, the setting management unit 36a transmits the received settings and the user ID of the login data 35a to the server 40.

[0050] The reading control unit 36b is a processing unit that reads the security tag ID from the security NFC tag. When the mobile terminal 30 is held over the security NFC tag, the reading control unit 36b reads the security tag ID via the reading unit 32.

[0051] The ID notification unit 36c is a processing unit that notifies the security tag ID and the user ID. When the reading control unit 36b reads the security tag ID, the ID notification unit 36c transmits the security tag ID and the user ID of the login data 35a to the server 40.

[0052] The login control unit 36d is a processing unit that performs login processing when controlling on / off of the security mode. The login control unit 36d displays a login screen on the display operation unit 31 upon receiving a login screen display instruction from the server 40.

[0053] In addition, when a user ID and password are entered from the display operation unit 31 while the login screen is displayed, the login control unit 36d compares the user ID and password with the login data 35a, and if they match, sends a user authentication notification to the server 40.

[0054] The execution confirmation unit 36e is a processing unit that performs execution confirmation of the control of turning on / off the security mode. When the execution confirmation unit 36e receives an instruction to display an execution confirmation screen from the server 40, it displays an execution confirmation screen on the display operation unit 31. Then, when the execution confirmation operation is accepted, it transmits an execution confirmation notification to the server 40.

[0055] The display control unit 36f is a processing unit that controls displays related to security. When the display control unit 36f receives a security mode on completion notification from the server 40, it displays on the display operation unit 31 that the security mode of the controller 50 has become on. When the display control unit 36f receives a security mode off completion notification from the server 40, it displays on the display operation unit 31 that the security mode of the controller 50 has become off.

[0056] Furthermore, when the display control unit 36f receives a locking abnormality notification from the server 40, it displays a locking abnormality display screen on the display operation unit 31.

[0057] Next, a specific example of data stored in the storage unit 35 of the mobile terminal 30 shown in Fig. 3 will be described. Fig. 4 is a diagram showing an example of the login data 35a shown in Fig. 3.

[0058] The login data 35a shown in FIG. 4 indicates a state in which the user ID is "TM123456" and the password is "1234".

[0059] <Server 40 Configuration> Next, a description will be given of the configuration of the server 40 shown in Fig. 2. Fig. 5 is a functional block diagram showing the configuration of the server 40 shown in Fig. 2. As shown in Fig. 5, the server 40 is connected to a display unit 41 and an input unit 42, and has a communication unit 44, a storage unit 45, and a control unit 46.

[0060] The display unit 41 is a liquid crystal panel, a display device, etc. The input unit 42 is a keyboard, a mouse, etc. The communication unit 44 is an interface unit for data communication with the mobile terminal 30 and the controller 50 via the Internet.

[0061] The storage unit 45 is a storage device such as a hard disk drive or non-volatile memory, and stores confirmation setting data 45a and security control data 45b. The confirmation setting data 45a is data indicating whether login authentication and execution confirmation are performed for each user ID. The security control data 45b is data that associates a security tag ID, a type of control to be performed by this security tag ID, and a controller ID indicating the controller to be controlled for each user ID, and is used when controlling security mode on / off.

[0062] The control unit 46 is a control unit that performs overall control of the server 40, and has a setting management unit 46a, a security control unit 46b, a confirmation control unit 46c, and a security notification unit 46d. In practice, these programs are loaded into a CPU and executed, causing the setting management unit 46a, the security control unit 46b, the confirmation control unit 46c, and the security notification unit 46d to execute their respective corresponding processes.

[0063] The setting management unit 46a is a processing unit that manages the confirmation setting data 45a. When the setting management unit 46a receives settings for login authentication and execution confirmation and a user ID from the mobile terminal 30, the setting management unit 46a stores the received data in the confirmation setting data 45a.

[0064] The security control unit 46b is a processing unit that controls the on / off of the security mode. When the security control unit 46b receives a user ID and a security tag ID from the mobile terminal 30, the security control unit 46b identifies the type of control and the controller ID associated with each received ID from the security control data 45b.

[0065] The confirmation control unit 46c is a processing unit that controls login authentication and execution confirmation. When the security control unit 46b specifies the type of control and the controller ID, the confirmation control unit 46c performs the following process.

[0066] If the login authentication in the confirmation setting data 45a for the received user ID is "Yes", a login screen display instruction is sent to the mobile terminal 30. Then, if a user authentication notification is received from the mobile terminal 30, the execution confirmation setting in the confirmation setting data 45a is confirmed. Also, if the login authentication in the confirmation setting data 45a for the received user ID is "No", the execution confirmation setting in the confirmation setting data 45a is confirmed.

[0067] If the execution confirmation in the confirmation setting data 45a for the received user ID is "Yes", an instruction to display an execution confirmation screen is sent to the mobile terminal 30. Then, if an execution confirmation notification is received from the mobile terminal 30, a confirmation completion notification is passed to the security notification unit 46d. Also, if the execution confirmation in the confirmation setting data 45a for the received user ID is "No", a confirmation completion notification is passed to the security notification unit 46d.

[0068] The security notification unit 46d is a processing unit that notifies instructions regarding the control of turning the security mode on / off. When the security notification unit 46d receives a confirmation completion notification from the confirmation control unit 46c, it performs the following process using the type of control and the controller ID identified by the security control unit 46b. If the type of control identified by the security control unit 46b is "security mode on", it transmits a security mode on signal, and if the type of control is "security mode off", it transmits a security mode off signal to the controller 50 corresponding to the controller ID identified by the security control unit 46b.

[0069] Furthermore, when the security notification unit 46d receives a security mode on completion notification, a security mode off completion notification, or a lock abnormality notification from the controller 50, it notifies the mobile terminal 30 of the received notification.

[0070] Next, a specific example of data stored in the storage unit 45 of the server 40 shown in Fig. 5 will be described. Fig. 6 is a diagram showing an example of the confirmation setting data 45a and the security control data 45b shown in Fig. 5.

[0071] The confirmation setting data 45a shown in Fig. 6(a) associates a state in which login authentication is "Yes" and execution confirmation is "Yes" with the user ID "TM123456", and associates a state in which login authentication is "No" and execution confirmation is "No" with the user ID "TM987654". Note that Fig. 6(a) shows an example in which login authentication and execution confirmation for a user ID are both set to "Yes" or both set to "No", but this is not limiting, and either login authentication or execution confirmation may be set to "Yes".

[0072] The security control data 45b shown in Figure 6 (b) corresponds to the user ID "TM123456" and security tag ID "KS234567" with the control type "security mode on" and "ABC56789" as the controller ID indicating the controller to be controlled, and corresponds to the user ID "TM123456" and security tag ID "KK345678" with the control type "security mode off" and "ABC56789" as the controller ID of the controller to be controlled.

[0073] In addition, the security control data 45b associates the control type with "security mode on" and "ABC54321" as the controller ID of the controlled object for the user ID "TM987654" and security tag ID "KS876543," and associates the control type with "security mode off" and "ABC54321" as the controller ID of the controlled object for the user ID "TM987654" and security tag ID "KK765432."

[0074] <Configuration of controller 50> Next, a description will be given of the configuration of the controller 50 shown in Fig. 2. Fig. 7 is a functional block diagram showing the configuration of the controller 50 shown in Fig. 2. As shown in Fig. 7, the controller 50 has a display unit 51, an operation unit 52, an external communication unit 53, an in-facility communication unit 54, and a control unit 56.

[0075] The display unit 51 is an output device such as a liquid crystal panel. The operation unit 52 is an input device such as a button or a switch. The external communication unit 53 is an interface unit for data communication with the server 40 via the Internet. The in-facility communication unit 54 is an interface unit for receiving detection signals from sensors installed in a facility such as a house.

[0076] The control unit 56 is a control unit that performs overall control of the controller 50, and includes a security control unit 56a and a locking management unit 56b. In practice, these programs are loaded into the CPU and executed, causing the security control unit 56a and the locking management unit 56b to execute the processes corresponding thereto.

[0077] The security control unit 56a is a processing unit that controls the on / off of the security mode. When the security control unit 56a receives a security mode on signal from the server 40, it passes a locking status confirmation instruction to the locking management unit 56b.

[0078] Furthermore, when the security control unit 56a receives a normal locking notification from the locking management unit 56b, it turns on the security mode and transmits a security mode on completion notification to the server 40.

[0079] Furthermore, upon receiving a security mode off signal from the server 40, the security control unit 56a turns off the security mode and notifies the server 40 of a security mode off completion notification.

[0080] The locking management unit 56b is a processing unit that manages the locking status. The locking management unit 56b receives a detection signal from the sensor via the facility communication unit 54.

[0081] In addition, when the locking management unit 56b receives an instruction to check the locking status from the security control unit 56a, if it has not received a detection signal from the sensor, it passes a locking success notification to the security control unit 56a.

[0082] In addition, when the locking management unit 56b receives an instruction to check the locking status from the security control unit 56a, if a detection signal has been received from the sensor, the locking management unit 56b transmits a locking abnormality notification to the server 40.

[0083] <Example of display on mobile terminal 30 according to embodiment 1> Next, a description will be given of an example of a display on the mobile terminal 30 according to the present embodiment 1. Fig. 8 is a diagram showing an example of a display on the mobile terminal 30 according to the present embodiment 1. When the mobile terminal 30 receives an instruction to display an execution confirmation screen from the server 40, it displays an execution confirmation screen, and when it receives a locking abnormality notification, it displays a locking abnormality display screen.

[0084] As shown in FIG. 8(a), the execution confirmation screen displays the message "The security situation will be changed. Are you sure?" along with confirmation buttons "Yes" and "No."

[0085] As shown in FIG. 8(b), the locking abnormality display screen displays the message "There is a locking abnormality. Please check," along with an "OK" confirmation button.

[0086] <Processing procedure for controlling security mode on / off according to the first embodiment> Next, a description will be given of a processing procedure relating to the on / off control of the security mode according to the embodiment 1. Fig. 9 to Fig. 11 are flowcharts showing the processing procedure relating to the on / off control of the security mode according to the embodiment 1.

[0087] The mobile terminal 30 reads data from the security NFC tag, and if the security tag ID cannot be obtained from this data (step S101; No), the mobile terminal 30 ends the process. If the security tag ID is obtained from the read data (step S101; Yes), the mobile terminal 30 transmits the security tag ID and the user ID to the server 40 (step S102).

[0088] When the server 40 receives the security tag ID and the user ID, the server 40 refers to the security control data 45b and uses the received security tag ID and user ID to identify the type of control and the controller to be controlled (step S103).The server 40 also refers to the confirmation setting data 45a, and if the login authentication of the received user ID is "not authenticated" (step S104; No), the server 40 proceeds to step S109, and if the login authentication is "authenticated" (step S104; Yes), the server 40 transmits an instruction to display a login screen to the mobile terminal 30 (step S105).

[0089] When the mobile terminal 30 receives the login screen display instruction, it displays the login screen (step S106), and if the login authentication is successful upon receiving the input of login information (step S107; Yes), it transmits a user authentication notification indicating that the login authentication has been successful, that is, that it has been confirmed that the operator is a legitimate user, to the server 40 (step S108). If the login authentication fails in step S107 (step S107; No), the mobile terminal 30 returns to step S106 and displays the login screen.

[0090] If the login authentication is "no" in step S104, or if the server 40 receives a user authentication notification from the mobile terminal, the server 40 refers to the execution confirmation setting in the confirmation setting data 45a. If the execution confirmation in the confirmation setting data 45a is "no" (step S109; No), the server 40 proceeds to step S114, and if the execution confirmation is "yes" (step S109; Yes), the server 40 transmits an instruction to display an execution confirmation screen to the mobile terminal 30 (step S110).

[0091] When the mobile terminal 30 receives the execution confirmation screen display instruction, it displays the execution confirmation screen shown in Fig. 8(a) (step S111), and if "Yes" is selected as the execution confirmation operation (step S112; Yes), it transmits an execution confirmation notification to the server 40 (step S113). Also, if "No" is selected as the execution confirmation operation in step S112 (step S112; No), the mobile terminal 30 ends the process.

[0092] If the type of control identified in step S103 is security mode on (step S114; Yes), the server 40 transmits a security mode on signal to the controller 50 (step S201).

[0093] When the controller 50 receives the security mode on signal, it checks the door lock state based on the reception state of the detection signal from the sensor (step S202), and if it receives a detection signal from the sensor, that is, if there is a lock abnormality (step S203; Yes), it transmits the door lock abnormality to the server 40 (step S204). If it does not receive a detection signal from the sensor and there is no lock abnormality (step S203; No), it controls the security mode to on (step S205) and transmits security mode on completion to the server 40 (step S206).

[0094] In step S205, the controller 50 controls the security mode to ON, starts the exit timer, and disables detection signals from preset sensors such as an open / close sensor installed at the entrance and a human presence sensor in the corridor while the exit timer is timing. This makes it possible to prevent unnecessary alarms from being generated due to the operator opening the entrance door or detecting the operator himself immediately after controlling the security mode to ON.

[0095] The server 40 transmits the received control result (door lock abnormality or security mode ON completion) to the mobile terminal 30 (step S207). When the mobile terminal 30 receives the control result (door lock abnormality or security mode ON completion), if the received control result is a door lock abnormality, it displays a message that the security mode could not be controlled to the ON state due to a door lock abnormality, and if the received result is security mode ON completion, it displays a message that the security mode has been turned ON (step S208), and ends the process.

[0096] If the type of control identified in step S103 is security mode off (step S114; No), the server 40 transmits a security mode off signal to the controller 50 (step S301).

[0097] When the controller 50 receives the security mode off signal, it controls the security mode to the off state (step S302), and transmits a security mode off completion to the server 40 (step S303).

[0098] The server 40 transmits the received security mode off completion to the mobile terminal 30 (step S304). Upon receiving the security mode off completion, the mobile terminal 30 displays a message indicating that the security mode of the controller 50 has been turned off (step S305), and ends the process.

[0099] As described above, the security system of this embodiment 1 is configured to read the security tag ID from the security NFC tag and use this read security tag ID to control the on / off of the security mode, so that the security mode can be set efficiently and accurately.

[0100] In the above embodiment 1, a configuration has been described in which a security tag ID is read from a security NFC tag and the security mode is turned on / off using the read security tag ID, but the present invention is not limited to this. It may also be configured to control the security mode on / off by inputting a PIN number or ID key or operating a smartphone app. In this case, it may also be configured to store the contents of the input or operation as history data so that the operation contents can be identified.

[0101] In the above embodiment 1, the configuration has been described in which the login screen and the execution confirmation screen are displayed and each screen accepts an operation, but the present invention is not limited to this. If no operation is performed within a predetermined time in steps S107 and S112 after the login screen and the execution confirmation screen are displayed, the mobile terminal displaying or notifying the user of the operation can be vibrated. This can prevent a situation in which a user thinks that the security mode has been switched on and off just by reading the security NFC tag, and leaves the security mode unattended.

[0102] Furthermore, in the above-mentioned first embodiment, authentication of the operator is performed by inputting a user ID and a password, but this is not limited to this, and authentication may be performed by biometric authentication such as fingerprint or face authentication.

[0103] In addition, in the above-mentioned embodiment 1, the type of control is determined in step S114, but it may be determined immediately after the type of control is specified in step S103. This simplifies the operation of the operator, for example, omitting login authentication regardless of the setting of the confirmation setting data when controlling the security mode to be on. Also, it is possible to notify the operator of a message that is easy to understand, such as displaying the content on the execution confirmation screen according to the type of control as "Do you want to start security?" when the type of control is security mode on, and "Do you want to cancel security?" when the type of control is security mode off, thereby preventing erroneous setting to security mode.

[0104] In addition, in the above embodiment 1, an example is described in which an NFC tag is used as an identification information retaining member for controlling the security mode of the security system to be on or off, but this is not limited to this, and any medium that can obtain identification information by a mobile terminal can be used, such as a two-dimensional code such as a barcode or QR code (registered trademark), or a contactless IC card such as a FeliCa (registered trademark) type IC card.

[0105] When a two-dimensional code is used as the identification information retaining member, the two-dimensional code is captured by a camera provided on the mobile terminal, and a recognition unit (not shown) of the mobile terminal analyzes the captured two-dimensional code to obtain the identification information carried by the two-dimensional code (corresponding to the "security tag ID" described in embodiment 1 above), and the identification information is then transmitted to server 40 via ID notification unit 36c.

[0106] Furthermore, when a contactless IC card is used as the identification information holding member, the identification information (corresponding to the "security tag ID" described in embodiment 1 above) carried on the contactless IC card is obtained by a transmitter / receiver unit (not shown) provided in the mobile terminal, and the identification information is transmitted to the server 40 via the ID notification unit 36c.

[0107] In addition, in the above embodiment 1, a smartphone is given as an example of a mobile terminal, but this is not limited to this, and any device that has the function of acquiring the identification information held by the identification information holding member and can transmit various information to the server 40 directly or via another communication device may be used, and a wearable device, tablet device, etc. may also be used.

[0108] [Embodiment 2] Incidentally, in the above-mentioned embodiment 1, a configuration was described in which a security tag ID is read from a security NFC tag and the security mode is controlled to be on / off using the read security tag ID, but the present invention is not limited to this. It can also be configured to notify a user that a mobile terminal has been left behind when the mobile terminal has been left behind in a house with the security mode on. In the present embodiment 2, a security system is described in which a user is notified that a mobile terminal has been left behind when the mobile terminal has been left behind in a house with the security mode on. Note that a case will be described in which the mobile terminal detection system according to the present invention is applied to a security system.

[0109] <Outline of security system according to the second embodiment> An overview of the security system according to the second embodiment will be described below. Fig. 12 is an explanatory diagram of the overview of the security system according to the second embodiment.

[0110] 12, in the security system according to the second embodiment, the controller 300 observes the Wi-Fi radio waves between the mobile terminal 100a and the Wi-Fi (registered trademark) router 400 (S11), and the controller 300 records the radio wave observation data of the pre-registered mobile terminal 100a (S12). After the controller 300 controls the security mode to be on (S13), if it detects from the observation data that the registered mobile terminal 100a is present in the house within a predetermined time range (S14), it transmits a notice that the mobile terminal 100a has been left behind to the server 200 (S15).

[0111] When the server 200 receives a notice that the mobile terminal 100a has been left behind from the controller 300, the server 200 notifies the mobile terminal 100b, which is registered as a notification destination, that the mobile terminal 100a has been left behind (S16).

[0112] In this way, the security system of this embodiment 2 is configured to notify the user if a mobile terminal is left behind in a home while the security mode is on, so that it can quickly and efficiently detect that a mobile terminal has been left behind in the home.

[0113] <Configuration of the mobile terminal 100> Next, the configuration of the mobile terminal 100 will be described. Fig. 13 is a functional block diagram showing the configuration of the mobile terminal 100 shown in Fig. 12. As shown in Fig. 13, the mobile terminal 100 has a display operation unit 31, a communication unit 33, a Wi-Fi communication unit 110, a storage unit 120, and a control unit 130. Note that a description of the same functional units as those of the mobile terminal 30 shown in Fig. 3 will be omitted.

[0114] The Wi-Fi communication unit 110 is an interface unit for communicating data on the Internet via the Wi-Fi router 400 using Wi-Fi, which is a short-range wireless communication, and holds a MAC address unique to the device of the mobile terminal 100. Even when there is no data to be transmitted or received for which the communication control unit 131 controls communication, the communication unit 33 establishes a link that enables data communication with the Wi-Fi router 400, as long as the mobile terminal 100 is participating in a wireless LAN to which the Wi-Fi router 400 belongs.

[0115] The storage unit 120 is a storage device formed of a non-volatile memory or a hard disk device, and stores the login data 35a and terminal data 121. The terminal data 121 includes a terminal ID and a MAC address.

[0116] The control unit 130 is a control unit that performs overall control of the mobile terminal 100, and has a setting management unit 36a, a login control unit 36d, a communication control unit 131, a registration unit 132, and an email control unit 133. In practice, by loading these programs into the CPU and executing them, the setting management unit 36a, the login control unit 36d, the communication control unit 131, the registration unit 132, and the email control unit 133 are caused to execute processes corresponding thereto.

[0117] The communication control unit 131 is a processing unit that controls communication via Wi-Fi. The communication control unit 131 performs data communication over the Internet via the Wi-Fi router 400 using Wi-Fi.

[0118] The registration unit 132 is a processing unit that registers the notification destination. When the registration unit 132 receives from the display operation unit 31 the controller ID of the controller 300 that detects the terminal when the terminal is left behind in the house and the telephone number of the destination to notify that the terminal has been left behind in the house, the registration unit 132 adds the terminal data 121 to the received data and transmits the result to the server 200 as notification destination data.

[0119] The mail control unit 133 is a processing unit that receives mail. When the mail control unit 133 receives mail from the server 200, the mail control unit 133 displays the mail on the display operation unit 31.

[0120] Next, a specific example of data stored in storage unit 120 of mobile terminal 100 shown in Fig. 13 will be described. Fig. 14 is a diagram showing an example of terminal data 121 shown in Fig. 13. Terminal data 121 shown in Fig. 14 indicates a state in which the terminal ID is "XYZ12345" and the MAC address is "12-34-56-78-9A-BC".

[0121] <Server 200 Configuration> Next, the configuration of server 200 shown in Fig. 12 will be described. Fig. 15 is a functional block diagram showing the configuration of server 200 shown in Fig. 12. As shown in Fig. 15, server 200 is connected to display unit 41 and input unit 42, and has communication unit 44, storage unit 210, and control unit 220. Note that a description of functional units similar to those of server 40 shown in Fig. 5 will be omitted.

[0122] The storage unit 210 is a storage device such as a hard disk drive or a non-volatile memory, and stores notification destination data 211. The notification destination data 211 is data indicating a telephone number or the like of a destination to notify when the mobile terminal 100 is left behind.

[0123] The control unit 220 is a control unit that performs overall control of the server 200, and includes a registration unit 221 and a misplacement notification unit 222. In practice, these programs are loaded into a CPU and executed, causing the registration unit 221 and the misplacement notification unit 222 to execute processes corresponding thereto.

[0124] The registration unit 221 is a processing unit that manages the notification destination data 211. When the registration unit 221 receives the notification destination data from the mobile terminal 100, the registration unit 221 stores the notification destination data in the notification destination data 211. Then, the registration unit 221 transmits the terminal ID as registration data to the controller 300 having the stored controller ID.

[0125] The misplacement notification unit 222 is a processing unit that notifies the user that the mobile terminal 100 has been left behind. When the misplacement notification unit 222 receives a misplacement notification from the controller 300, the misplacement notification unit 222 identifies a notification destination telephone number from the notification destination data 211 using the controller ID and terminal ID included in the misplacement notification. Then, the misplacement notification unit 222 notifies the notification destination telephone number that the mobile terminal 100 has been left behind.

[0126] Next, a specific example of data stored in storage unit 210 of server 200 shown in Fig. 15 will be described. Fig. 16 is a diagram showing an example of notification destination data 211 shown in Fig. 15.

[0127] 16, the notification destination data 211 associates the user ID "TM123456" representing the operator of the mobile terminal and the contractor of the security service with the contracted controller IDs "ABC56789" and "ABC54321". Also, the controller ID "ABC56789" is associated with the terminal ID "XYZ12345" and the notification destination telephone number "09023456789", and the controller ID "ABC54321" is associated with the terminal ID "XYZ98765" and the notification destination telephone number "08087654321". Note that it is also possible to register a plurality of terminal IDs in association with one controller 300.

[0128] <Configuration of controller 300> Next, the configuration of the controller 300 shown in Fig. 12 will be described. Fig. 17 is a functional block diagram showing the configuration of the controller 300 shown in Fig. 12. As shown in Fig. 17, the controller 300 has a display unit 51, an operation unit 52, a receiving unit 310, an external communication unit 53, an in-facility communication unit 54, a storage unit 320, and a control unit 330. Note that a description of the same functional units as those of the controller 50 shown in Fig. 7 will be omitted.

[0129] The receiving unit 310 is an interface unit for receiving Wi-Fi radio waves. The storage unit 320 is a storage device such as a hard disk drive or a non-volatile memory, and stores registered mobile terminal data 321. The registered mobile terminal data 321 is data indicating the terminal ID and MAC address of the mobile terminal 100 that is the target for detecting Wi-Fi radio waves.

[0130] The control unit 330 is a control unit that performs overall control of the controller 300, and has a security control unit 56a, a locking management unit 56b, a registration unit 331, a misplacement detection unit 332, and a misplacement notification unit 333. In practice, by loading these programs into a CPU and executing them, the security control unit 56a, the locking management unit 56b, the registration unit 331, the misplacement detection unit 332, and the misplacement notification unit 333 will each execute a process corresponding to the program.

[0131] Registration unit 331 is a processing unit that manages registered portable terminal data 321. When registration unit 331 receives registration data from server 200, it stores the registration data in registered portable terminal data 321.

[0132] The misplacement detection unit 332 is a processing unit that detects the mobile terminal 100 left behind in the house. The misplacement detection unit 332 observes Wi-Fi radio waves in the house, and when it detects a frame including a MAC address registered in the registered mobile terminal data 321, it updates the last observed date and time of the MAC address in the MAC address observation table 322. After the security mode is turned on by the security control unit 56a, it refers to the MAC address observation table 322, extracts a MAC address whose last observed date and time is within a predetermined time range, and passes a detection notification including this MAC address to the misplacement notification unit 333.

[0133] The misplacement notification unit 333 is a processing unit that notifies a misplacement notification. When the misplacement notification unit 333 receives a detection notification from the misplacement detection unit 332, the misplacement notification unit 333 notifies the server 200 of the misplacement notification including the MAC address and the controller ID of the own device included in the detection notification.

[0134] Next, a specific example of data stored in storage unit 320 of controller 300 shown in Fig. 17 will be described. Fig. 18 is a diagram showing an example of registered mobile terminal data 321 and MAC address observation table 322 shown in Fig. 17. Registered mobile terminal data 321 shown in Fig. 18(a) indicates a state in which the terminal ID is "XYZ12345" and the MAC address is "12-34-56-78-9A-BC".

[0135] The MAC address observation table 322 shown in Figure 18 (b) indicates that the date and time when a frame containing the MAC address "12-34-56-78-9A-BC" was last observed was "2023 / 03 / 23 10:00", and the date and time when a frame containing the MAC address "34-56-78-9A-BC-DE" was last observed was "2023 / 03 / 22 00:00".

[0136] <Processing procedure for notifying of leaving behind according to the second embodiment> Next, a description will be given of a process procedure for notifying a user of a misplacement according to the present embodiment 2. Fig. 19 is a flowchart showing a process procedure for notifying a user of a misplacement according to the present embodiment 2.

[0137] The controller 300 observes Wi-Fi radio waves within the home (step S401), refers to the Ethernet header in the data link layer frame of the observed Wi-Fi radio waves, and if the registered mobile terminal data 321 contains a registered MAC address, records the observation date and time as the last observation date and time in the MAC address observation table 322 (step S402).

[0138] The object of observation of Wi-Fi radio waves is Layer 2 of the OSI reference model, that is, frame exchange at the data link layer. At the data link layer, the MAC address is used to identify the other party exchanging data, and when the controller 300 observes a state in which a link with the Wi-Fi router 400, which is the closest connection partner from the viewpoint of the mobile terminal 100, is established, it is possible to observe that the MAC addresses of the sender and destination are included in the Ethernet header of the frame. Since communication above the network layer becomes slow while the OS is in a paused state, such as when the mobile terminal 100 is in standby, by detecting the communication state of the data link layer and extracting the MAC address in the frame, it is possible to detect that the mobile terminal 100 that has been left behind is located in the house, even when the owner of the mobile terminal 100 is not in the house.

[0139] If the security mode of the controller 300 is turned on (step S403; Yes), the clock starts from that point. If the security mode of the controller 300 is not turned on (step S403; No), the controller 300 returns to step S401 and observes the Wi-Fi radio waves of the mobile terminal 100. Even after the security mode is turned on, the controller 300 observes the Wi-Fi radio waves in the house (step S404), refers to the Ethernet header in the frame of the data link layer of the observed Wi-Fi radio waves, and if the registered MAC address is included in the registered mobile terminal data 321, records the observation date and time as the last observation date and time in the MAC address observation table 322 (step S405). After a predetermined time has elapsed since the security mode was turned on (step S406; Yes), the MAC address observation table 322 is referred to, and if a MAC address whose last observation date and time is later than the date and time when the security mode was last turned on is detected (step S407; Yes), a notice of leaving is sent to the server 200 together with the terminal ID corresponding to the MAC address and the controller ID of the own device (step S408). Before the predetermined time has elapsed since the security mode was turned on (step S406; No), the process returns to step S404 to observe the Wi-Fi radio waves. Note that the waiting time in step S406 is desirably a length that allows at least several frames to be exchanged between the mobile terminal 100 and the Wi-Fi router 400 in the data link layer while the OS of the mobile terminal 100 is in standby. Note that the MAC address extracted at this time may be one other than the MAC address of the mobile terminal 100 carried by the operator of the security mode. If no MAC address whose last observation date and time is later than the date and time when the security mode was last turned on is detected in the MAC address observation table 322 (step S407; No), the process returns to step S401 and continues observing the Wi-Fi radio waves of the mobile terminal 100.

[0140] When the server 200 receives a misplacement notification from the controller 300, the server 200 uses the controller ID and the terminal ID included in the misplacement notification to extract a notification destination telephone number from the notification destination data 211. Then, the server 200 notifies the notification destination telephone number that the mobile terminal 100 has been left behind (step S407), and ends the process.

[0141] As described above, the security system of this embodiment 2 is configured to notify the user if a resident leaves a mobile terminal behind in the home while the security mode is on, so that it can quickly and efficiently detect that a mobile terminal has been left behind in the home.

[0142] In addition to notifying the user of the mobile terminal left behind when the security mode is turned on, a method of checking the mobile terminal left behind at any time from outside the home will be described. Fig. 20 is a flowchart of a process for checking the status of the mobile terminal left behind at any time, which is related to the notification of the mobile terminal left behind according to the second embodiment.

[0143] The controller 300 observes Wi-Fi radio waves within the home (step S501), refers to the Ethernet header in the data link layer frame of the observed Wi-Fi radio waves, and if the registered mobile terminal data 321 contains a registered MAC address, records the observation date and time in the MAC address observation table 322 as the last observation date and time of the MAC address (step S502).

[0144] When the user operates the display operation unit 31 of the mobile terminal 100, specifies the controller ID that he / she wishes to confirm, and then sends a confirmation request for the location status of the mobile terminal 100 within the home together with his / her own user ID (step S503), the server 200 sends the confirmation request to the controller 300 of that controller ID (step S504).

[0145] Controller 300 refers to MAC address observation table 322 stored in storage unit 320, extracts MAC addresses whose last observation date and time is within a predetermined time range before the time when the confirmation request was received (step S505), and notifies server 200 of the terminal ID corresponding to the MAC address in registered mobile terminal data 321 stored in storage unit 320 as a result (step S506). Then, it is determined whether or not to end the process (step S509), and if to end the process (step S509; Yes), the process ends as it is. On the other hand, if not to end the process (step S509; No), the process proceeds to step S501.

[0146] Server 200 notifies mobile terminal 100 of the result notification received from controller 300 (step S507), and mobile terminal 100 displays the result (step S508). Note that it is desirable to set the predetermined time here to a length that allows at least several frames to be exchanged between mobile terminal 100 and Wi-Fi router 400 in the data link layer while the OS of mobile terminal 100 is in standby state.

[0147] At this time, the user may transmit a confirmation request from the mobile terminal 100 without specifying a controller ID, and the server 200 may transmit the confirmation request to the controllers 300 having all the controller IDs corresponding to the user ID in the notification destination data 211. In this case, the server 200 notifies the mobile terminal 100 of the user of the confirmation result for each controller ID.

[0148] In addition, when the server 200 notifies the user's mobile terminal 100 of the confirmation result, the server 200 may be configured to notify the name, pre-registered nickname, and phone number of the owner of the mobile terminal 100 determined to be located within the home.

[0149] In the above-mentioned second embodiment, when a mobile terminal is left behind in a house with the security mode on, a configuration is described in which the fact that the mobile terminal has been left behind is notified to a registered mobile terminal, but the present invention is not limited to this. When it is determined that a person is at home by detecting the mobile terminal of the person at home, and when it is detected that the mobile terminal of a person determined as an outsider by detection by a sensor or by setting to go out by operating an operating device or the like is located within the house, it is also possible to configure so that the fact that the mobile terminal has been left behind is displayed on a controller or an operating device, or a light or sound is emitted from the controller or the like. Furthermore, it is also possible to notify the situation of other residents' mobile terminals being left behind by the controller or the like.

[0150] In the above-mentioned second embodiment, the server notifies the registered mobile terminal of the fact that the mobile terminal has been left behind by email, but the present invention is not limited to this. The MAC address observation table 322 stored in the storage unit 320 of the controller 300 can be synchronized with the server 200 together with the controller ID, and the status of whether all mobile terminals located in the house have been left behind can be viewed through a web browser or an app.

[0151] In addition, the configurations illustrated in the above embodiments are merely functional schematics, and are not necessarily physically configured as illustrated. In other words, the form of distribution and integration of each device is not limited to that illustrated, and all or part of the devices can be functionally or physically distributed and integrated in any unit according to various loads, usage conditions, etc. [Industrial Applicability]
