Mode for Carrying Out the Invention

[0011] (1) Embodiment 1 (1-1) Overview Hereinafter, the overview of the security system 100 according to Embodiment 1 will be described with reference to FIG. 1.

[0012] The security system 100 according to Embodiment 1 is a system that is used in a building such as a detached house and monitors the presence or absence of abnormalities in the building. Note that the building in which the security system 100 of Embodiment 1 is used is not limited to a detached house, and may be a dwelling unit in an apartment building. However, in the following embodiments, a detached house will be described as an example.

[0013] As shown in FIG. 1, the security system 100 according to Embodiment 1 includes a locking / unlocking unit 14 and a control unit 23. The locking / unlocking unit 14 unlocks the door lock of a building according to the acquired attributes of user X1. The control unit 23 is configured to be communicable with the locking / unlocking unit 14, and controls at least one of security setting and release for the building according to the attributes of user X1. Note that, as used in the present disclosure, "security setting" means setting to monitor the presence or absence of abnormalities in the building where the security system 100 is used, and "security release" means setting not to monitor the presence or absence of abnormalities in the building where the security system 100 is used.

[0014] In the security system 100 according to Embodiment 1, security setting or unlocking of the building is controlled according to the attributes of user X1 who has caused the locking / unlocking unit 14 to unlock the door lock of the building. For this reason, for example, when it is difficult to reset the security or user X1 (such as a child or an elderly person) for whom such an operation is not desired causes the locking / unlocking unit 14 to unlock the door lock of the building, the control unit 23 can control at least one of security setting and release according to the attributes of the user. Therefore, the operation of resetting the security by the user becomes unnecessary. That is, the security system 100 according to Embodiment 1 has the effect of improving the convenience of user X1. Further, in the security system 100 according to Embodiment 1, when an unexpected person (such as a burglar) unlocks the door lock, the control unit 23 does not control the security setting, so that it is possible to suppress a decrease in security. From the above, the security system 100 according to Embodiment 1 has the advantage of being able to achieve both improvement in convenience and suppression of a decrease in security.

[0015] (1-2) Detailed Configuration (1-2-1) Security System Hereinafter, the detailed configuration of the security system 100 according to Embodiment 1 will be described with reference to FIGS. 1 to 3.

[0016] The security system 100 is a system that monitors the presence or absence of abnormalities in a building according to the attributes of user X1 (see FIG. 1) who has unlocked the door lock of the building. In other words, the security system 100 of Embodiment 1 is a system that provides security for the building according to the attributes of user X1 who has unlocked the door lock of the building.

[0017] As shown in FIG. 1, the security system 100 includes a locking / unlocking device 1, a control device 2, an operating device 3, and a security device 4.

[0018] (1-2-2) Locking / Unlocking Device The locking / unlocking device 1 is a device that locks and unlocks the door lock of the building. More specifically, the locking / unlocking device 1 unlocks the door lock of the building according to the attributes of the approaching user X1. Note that the "door lock" referred to in the present disclosure is a lock of a door provided at the entrance of the building, and is, for example, an electric lock.

[0019] As shown in FIG. 1, the locking / unlocking device 1 includes an acquisition unit 11, an unlocking determination unit 12, a storage unit 13, a locking / unlocking unit 14, and a communication unit 15.

[0020] (Acquisition Unit) The acquisition unit 11 acquires the attributes of user X1. More specifically, the acquisition unit 11 acquires information regarding the attributes of user X1. The acquisition unit 11 of Embodiment 1 receives an identification signal transmitted from the mobile terminal X11 owned by user X1, and acquires the identification information included in the identification signal as information regarding the attributes of user X1. The identification information referred to here is information that is associated in advance in a one-to-one correspondence with each mobile terminal X11. In the present disclosure, the mobile terminal X11 is assumed to be a smartphone or a tablet computer owned by user X1. Note that the mobile terminal X11 may be a dedicated terminal (for example, a remote control key) for use in the security system 100.

[0021] (Unlocking Determination Unit) The unlocking determination unit 12 determines whether to unlock the door lock of the building by the unlocking and locking unit 14 based on the attributes of user X1 acquired by the acquisition unit 11. More specifically, when the attributes of user X1 acquired by the acquisition unit 11 match the pre-registered attributes, the unlocking determination unit 12 determines to unlock the door lock of the building by the unlocking and locking unit 14. On the other hand, when the attributes of user X1 acquired by the acquisition unit 11 do not match the pre-registered attributes, the unlocking determination unit 12 determines not to unlock the door lock of the building by the unlocking and locking unit 14.

[0022] (Memory unit) The memory unit 13 stores the attributes of the residents of the building registered in advance. When the attributes of user X1 acquired by the acquisition unit 11 match the attributes of the residents of the building stored in the memory unit 13, the unlocking determination unit 12 determines to unlock the door lock of the building by the unlocking and locking unit 14. On the other hand, when the attributes of user X1 acquired by the acquisition unit 11 do not match the attributes of the residents of the building stored in the memory unit 13, the unlocking determination unit 12 determines not to unlock the door lock of the building by the unlocking and locking unit 14.

[0023] The memory unit 13 includes a rewritable non-volatile memory such as an EEPROM (Electrically Erasable Programmable Read-Only Memory), for example.

[0024] (Unlocking and locking unit) The unlocking and locking unit 14 locks and unlocks the door lock of the building. The unlocking and locking unit 14 in Embodiment 1 is a mechanism for locking and unlocking the door lock of the building.

[0025] The unlocking and locking unit 14 unlocks the door lock of the building based on the determination result of the unlocking determination unit 12. More specifically, when the attributes of user X1 acquired by the acquisition unit 11 match the attributes of the residents of the building, the unlocking and locking unit 14 unlocks the door lock of the building. In short, the unlocking and locking unit 14 unlocks the door lock of the building according to the attributes of user X1 acquired by the acquisition unit 11.

[0026] In the following description, as shown in FIG. 1, it is assumed that user X1 is a child included in the residents of the building, and the case where the child unlocks the door lock of the building is considered. That is, the acquisition unit 11 acquires information that the attribute of user X1 is a child included in the residents of the building. As a result, since the attribute of user X1 acquired by the acquisition unit 11 matches the attribute of the residents of the building, the unlocking determination unit 12 determines to cause the unlocking / locking unit 14 to unlock the door lock of the building.

[0027] (Communication unit) The communication unit 15 is configured to be able to communicate with a communication unit 24 of the control device 2 described later. The communication unit 15 of the first embodiment is a communication module capable of wireless communication with the communication unit 24 of the control device 2. The communication unit 15 may directly perform wireless communication with the communication unit 24 of the control device 2, or may indirectly perform wireless communication via a repeater or the like. For example, the communication unit 15 is a communication module capable of wireless communication conforming to a communication standard such as Wi-Fi (registered trademark). Note that the communication unit 15 may be a communication module capable of wired communication conforming to a communication standard such as a wired LAN (Local Area Network).

[0028] After the unlocking / locking unit 14 unlocks the door lock of the building, the communication unit 15 transmits an attribute signal Si1 including information regarding the attribute of user X1 to the communication unit 24 of the control device 2.

[0029] (1-2-3) Control device The control device 2 is a device that controls at least part of the security settings and releases for the building. That is, the control device 2 is a device that controls a security device 4 described later. The control device 2 of the first embodiment controls both the security settings and releases for the building.

[0030] As shown in FIG. 1, the control device 2 includes an attribute determination unit 21, a storage unit 22, a control unit 23, and a communication unit 24.

[0031] The control device 2 preferably includes a computer system. In the computer system, each function of the attribute determination unit 21 and the control unit 23 is realized by a processor such as a CPU (Central Processing Unit) or an MPU (Micro Processing Unit) reading and executing a program stored in a memory. The computer system includes, as a main hardware configuration, a processor that operates according to a program. The type of the processor is not limited as long as it can realize functions by executing a program. The processor is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or an LSI (Large Scale Integration). Here, although referred to as an IC or an LSI, the name may change depending on the degree of integration, and it may be referred to as a system LSI, a VLSI (Very Large Scale Integration), or a ULSI (Ultra Large Scale Integration). A field programmable gate array (FPGA) programmed after the manufacture of the LSI, or a reconfigurable logic device capable of reconfiguring the bonding relationship inside the LSI or setting up circuit sections inside the LSI can also be used for the same purpose. The plurality of electronic circuits may be integrated on one chip or provided on a plurality of chips. The plurality of chips may be aggregated into one device or provided in a plurality of devices. Note that the program may be provided through a telecommunication line or provided by being recorded on a recording medium such as a memory card.

[0032] (Attribute determination unit) The attribute determination unit 21 determines whether the attribute of the user X1 acquired by the acquisition unit 11 of the locking / unlocking device 1 matches the pre-registered attribute. The attribute determination unit 21 in Embodiment 1 determines whether the attribute of the user X1 included in the attribute signal Si1 matches a candidate attribute (to be described later) stored in the storage unit 13 when the communication unit 24 receives the attribute signal Si1 from the communication unit 15 of the locking / unlocking device 1.

[0033] (Storage unit) The storage unit 22 associates and stores candidate attributes, which are candidates for attributes of the user X1 that can be acquired by the acquisition unit 11 of the locking / unlocking device 1, with at least one area among a plurality of areas inside the building. In the storage unit 22 of the first embodiment, attributes of the user X1 for whom security resetting work is difficult or who is not desired to perform the work (e.g., children, elderly people, etc.) are registered and stored in advance as candidate attributes. Specifically, the candidate attributes stored in the storage unit 13 are attributes of residents of the building for whom security resetting work is difficult or who are not desired to perform the work.

[0034] The storage unit 22 stores a table linking candidate attributes, which are candidates for attributes of the user X1 that can be acquired by the acquisition unit 11 of the locking / unlocking device 1, with at least one area among a plurality of areas inside the building, as shown in Table 1 below. In the table stored in the storage unit 22, for example, the candidate attribute "child" is linked to two areas, which are assigned to a "living room" and a "children's room" among a plurality of areas inside the building. Also, the candidate attribute "elderly" is linked to two areas, which are assigned to a "living room" and a "bedroom" among a plurality of areas inside the building.

[0035] [Table 1]

[0036] The storage unit 22 includes a rewritable non-volatile memory such as an EEPROM.

[0037] (Control unit) The control unit 23 controls at least one of setting and releasing security for the building. The control unit 23 of the first embodiment controls both setting and releasing security for the building. The control unit 23 is configured to be able to communicate with both the acquisition unit 11 and the locking / unlocking unit 14 of the locking / unlocking device 1 via the communication unit 24 and the communication unit 15 of the locking / unlocking device 1.

[0038] When the attribute of user X1 acquired by acquisition unit 11 does not match the pre-registered attribute, control unit 23 controls the setting and release of security for the building according to the operation on operation device 3 by user X1. More specifically, when attribute determination unit 21 determines that the attribute of user X1 acquired by acquisition unit 11 does not match the pre-registered attribute, control unit 23 controls the setting and release of security for the building according to the operation on operation device 3 by user X1 (for example, a guardian or cohabitant who is a resident other than a child or an elderly person) who can reset the security. The control unit 23 in Embodiment 1 controls the setting and release of security for the building according to the operation on operation device 3 by user X1 based on operation signal Si2 received from communication unit 33 of operation device 3 via communication unit 24 when attribute determination unit 21 determines that the attribute of user X1 acquired by acquisition unit 11 does not match the pre-registered attribute.

[0039] More specifically, when the control unit 23 receives the attribute signal Si1 from the communication unit 15 of the locking and unlocking device 1 via the communication unit 24 and the attribute determination unit 21 determines that the attribute of the user X1 does not match the pre-registered attribute, the control unit 23 controls the security of the building to shift from the warning mode M1 (see FIG. 2) to the warning cancellation confirmation grace period T1. In short, when the attribute of the user X1 acquired by the acquisition unit 11 is a guardian or a co-resident, the control unit 23 controls the security of the building to shift from the warning mode M1 to the warning cancellation confirmation grace period T1. When the user X1 performs an operation to reset the security within the warning cancellation confirmation grace period T1 using the operation device 3, the control unit 23 shifts the security of the building from the warning cancellation confirmation grace period T1 to the non-warning mode M2. On the other hand, when the user X1 does not perform an operation to reset the security within the warning cancellation confirmation grace period T1 using the operation device 3, the security device 4, which will be described later, detects the unlocking of the door lock by the user X1 as an abnormality in the building. Note that the "warning mode M1" referred to in the present disclosure is a mode in which security is set in all areas among a plurality of areas inside the building or security is set. The "non-warning mode M2" is a mode in which security is released in all areas among a plurality of areas inside the building or security is released (that is, security is not set). Also, the "warning cancellation confirmation grace period T1" referred to in the present disclosure is a time during which the security device 4 does not detect the presence or absence of an abnormality in the building, and the length of the "warning cancellation confirmation grace period T1" is preset.

[0040] On the one hand, when the attribute of user X1 acquired by the acquisition unit 11 matches the pre-registered attribute, the control unit 23 controls the setting and cancellation of the security for the building according to the attribute of user X1 for which the unlocking unit 14 has unlocked the door lock of the building (i.e., the attribute acquired by the acquisition unit 11). The control unit 23 of Embodiment 1 maintains the state in which security is set and controls so that the unlocking of the door lock by user X1 is not detected as abnormal when the attribute of user X1 acquired by the acquisition unit 11 matches the pre-registered attribute. More specifically, when the attribute determination unit 21 determines that the attribute of user X1 acquired by the acquisition unit 11 matches the pre-registered attribute, the control unit 23 of Embodiment 1 maintains the state in which security is set and controls so that the unlocking of the door lock by user X1 is not detected as abnormal. According to this configuration, it is difficult to re-set the security, or the work of re-setting the security by user X1 (for example, children or the elderly) for whom such work is not desired becomes unnecessary, and the convenience is improved. Further, since the unlocking of the door lock by an unexpected person (for example, a burglar) is detected as abnormal, the effect of suppressing the reduction of security can be achieved. From the above, the security system 100 of Embodiment 1 has the advantage that it can more surely achieve both the improvement of convenience and the suppression of the reduction of security.

[0041] More specifically, when the communication unit 24 receives the attribute signal Si1 from the communication unit 15 of the unlocking device 1, the control unit 23 of Embodiment 1 maintains the security for the building in the warning mode M1 (see FIG. 2) and controls so that the unlocking of the door lock by user X1 is not detected as abnormal when the attribute determination unit 21 determines that the attribute of user X1 matches the pre-registered attribute. In short, when the attribute of user X1 acquired by the acquisition unit 11 is a child or an elderly person, the control unit 23 of Embodiment 1 maintains the security for the building in the warning mode M1 and controls so that the unlocking of the door lock by user X1 is not detected as abnormal.

[0042] The control unit 23 of Embodiment 1 controls so that the unlocking of the door lock by the user X1 is not detected as abnormal, and releases the security in at least one area associated with a candidate attribute that matches the attribute of the user X1 among a plurality of areas inside the building. More specifically, based on the table stored in the storage unit 22, the control unit 23 releases the security in at least one area associated with a candidate attribute that matches the attribute of the user X1 acquired by the acquisition unit 11 among the plurality of areas inside the building. As an example, when the attribute of the user X1 acquired by the acquisition unit 11 is "child", the control unit 23 releases the security in two areas respectively allocated to the "living room" and the "children's room" among the plurality of areas inside the building. According to the above configuration, the control unit 23 can set the security suitable for the attribute of the user X1 who unlocked the door lock, and has the effect of suppressing the misdetection of the abnormality of the building. That is, there is an advantage that the convenience is further improved.

[0043] More specifically, the control unit 23 controls to shift the security for the building from the warning mode M1 to the partial warning mode M3 (see FIG. 2). Note that the "partial warning mode M3" referred to in the present disclosure is a mode in which the security in at least one area associated with a candidate attribute that matches the attribute of the user X1 acquired by the acquisition unit 11 among the plurality of areas inside the building is released, or the security is already released.

[0044] Further, when user X1 goes out of the building, the control unit 23 controls the security setting and release for the building according to the operation on the operation device 3 by user X1 based on the operation signal Si2 received from the communication unit 33 of the operation device 3. More specifically, when the control unit 23 receives an operation signal Si2 indicating that the operation device 3 has received the operation of user X1 when user X1 goes out of the building, the control unit 23 controls the security for the building to shift from the non-alarm mode M2 (see FIG. 2) to the alarm set confirmation grace period T2. After the preset alarm set confirmation grace period T2 has elapsed, the control unit 23 shifts the security for the building from the alarm set confirmation grace period T2 to the alarm mode M1. User X1 goes out through the door provided at the entrance of the building within the alarm set confirmation grace period T2. Note that the "alarm set confirmation grace period T2" referred to in the present disclosure is the time during which the security device 4 does not detect the presence or absence of an abnormality in the building, and the length of the "alarm set confirmation grace period T2" is preset.

[0045] (Communication unit) The communication unit 24 is configured to be able to communicate with both the communication unit 15 of the locking and unlocking device 1 and the communication unit 33 of the operation device 3 described later. The communication unit 24 in Embodiment 1 is a communication module capable of wireless communication with both the communication unit 15 of the locking and unlocking device 1 and the communication unit 33 of the operation device 3. The communication unit 24 may directly perform wireless communication with the communication unit 15 and the communication unit 33, or may indirectly perform wireless communication via a repeater or the like. For example, the communication unit 24 is a communication module capable of wireless communication compliant with a communication standard such as Wi-Fi (registered trademark). Note that the communication unit 24 may be a communication module capable of wired communication compliant with a communication standard such as a wired LAN.

[0046] The communication unit 24 outputs the operation signal Si2 received from the communication unit 33 of the operation device 3 to the control unit 23. Further, the communication unit 24 outputs an attribute signal Si1 including information regarding the attribute of user X1 received from the communication unit 15 of the locking and unlocking device 1 to the attribute determination unit 21.

[0047] (1-2-4) Operation device As shown in FIG. 1, the operation device 3 includes an operation unit 31, a display unit 32, and a communication unit 33.

[0048] (Operation Unit) The operation unit 31 receives an operation of user X1 for setting or releasing security. The operation unit 31 receives an operation for setting or releasing security after user X1 unlocks the door lock. Further, the operation unit 31 receives an operation for setting security when user X1 goes out of the building.

[0049] (Display Unit) The display unit 32 displays the state in which security is set. More specifically, the display unit 32 displays whether security is set or released. The display unit 32 of Embodiment 1 displays which mode among the security warning mode M1, non-warning mode M2, partial warning mode M3, and the reporting mode M4 (see FIG. 2) described later. More specifically, the display unit 32 of Embodiment 1 includes four light-emitting elements corresponding to each of the warning mode M1, non-warning mode M2, partial warning mode M3, and reporting mode M4, and causes the light-emitting element corresponding to the current mode of security among the four light-emitting elements to emit light.

[0050] (Communication Unit) The communication unit 33 is configured to be able to communicate with the communication unit 24 of the control device 2. The communication unit 33 of Embodiment 1 is a communication module capable of wireless communication with the communication unit 24 of the control device 2. The communication unit 33 may directly perform wireless communication with the communication unit 24, or may indirectly perform wireless communication via a repeater or the like. For example, the communication unit 33 is a communication module capable of wireless communication compliant with a communication standard such as Wi-Fi (registered trademark). Note that the communication unit 15 may be a communication module capable of wired communication compliant with a communication standard such as a wired LAN.

[0051] The communication unit 33 transmits an operation signal Si2 indicating that it has received an operation of user X1 for setting or releasing security to the communication unit 24 of the control device 2.

[0052] (1-2-5) Security device The security device 4 is a device that detects the presence or absence of an abnormality in a building based on the control content by the control device 2. The security device 4 detects the presence or absence of an abnormality in the building in a state where security for the building is set by the control unit 23 of the control device 2. "Abnormality" as referred to in the present disclosure assumes, for example, that an unexpected person (such as a burglar) enters the building through an opening such as a door or window of the building.

[0053] More specifically, the security device 4 detects the presence or absence of an abnormality in all of a plurality of areas inside the building in a state where security for the building is set to the warning mode M1 by the control unit 23 of the control device 2. Further, the security device 4 detects the presence or absence of an abnormality in at least one area associated with a candidate attribute that matches the attribute of the user X1 acquired by the acquisition unit 11 among a plurality of areas inside the building in a state where security is set to the partial warning mode M3 by the control unit 23 of the control device 2. Note that the security device 4 does not detect the presence or absence of an abnormality in the building in a state where security is set to the non-warning mode M2 by the control unit 23 of the control device 2.

[0054] When the security device 4 detects an abnormality in a state where security for the building is set to the warning mode M1 or the partial warning mode M3 by the control unit 23 of the control device 2, it controls to shift from the warning mode M1 or the partial warning mode M3 to the alarm mode M4. Note that "alarm mode M4" as referred to in the present disclosure is a mode for notifying the user X1 that an abnormality has occurred in the building.

[0055] As described above, the group G1 (see FIG. 2) including the warning mode M1, the partial warning mode M3, and the reporting mode M4 is a mode in which security is set in the security system 100. On the other hand, the group G2 (see FIG. 2) including the non-warning mode M2 is a mode in which security is released in the security system 100.

[0056] The security device 4 of Embodiment 1 is a detection sensor provided at an opening such as a door or window of a building, and detects that the opening has been opened. By detecting that the opening has been opened, the detection sensor detects that an unexpected person (for example, a burglar) has entered the building through the opening.

[0057] (1-3) Security method When user X1 attempts to unlock the door of the building, the security method of the security system 100 of Embodiment 1 for monitoring the presence or absence of abnormalities in the building will be described with reference to the flowchart of FIG. 3.

[0058] As shown in FIG. 1, the security method of Embodiment 1 includes an acquisition step ST11, an unlocking determination step ST12, an unlocking step ST13, an attribute transmission step ST14, an attribute determination step ST15, a first control step ST16, and a second control step ST17. The first control step ST16 corresponds to the control step of the present invention.

[0059] In the acquisition step ST11, the acquisition unit 11 acquires the attributes of user X1. In the acquisition step ST11 of Embodiment 1, the acquisition unit 11 receives an identification signal transmitted from the mobile terminal X11 owned by user X1, and acquires the identification information included in the identification signal as information regarding the attributes of user X1. In the unlocking determination step ST12, the unlocking determination unit 12 determines whether to cause the locking / unlocking unit 14 to unlock the building door lock based on the attributes of user X1 acquired by the acquisition unit 11. More specifically, in the unlocking determination step ST12, the unlocking determination unit 12 determines to cause the locking / unlocking unit 14 to unlock the building door lock when the attributes of user X1 acquired by the acquisition unit 11 match the pre-registered attributes. On the other hand, in the unlocking determination step ST12, the unlocking determination unit 12 determines not to cause the locking / unlocking unit 14 to unlock the building door lock when the attributes of user X1 acquired by the acquisition unit 11 do not match the pre-registered attributes. When the unlocking determination unit 12 determines not to cause the locking / unlocking unit 14 to unlock the building door lock (ST12: NO), the locking / unlocking unit 14 does not unlock the building door lock according to the acquired attributes of the user. That is, when the unlocking determination unit 12 determines not to cause the locking / unlocking unit 14 to unlock the building door lock (ST12: NO), the locking / unlocking unit 14 does not perform an operation.

[0060] On the other hand, when the unlocking determination unit 12 determines to cause the locking / unlocking unit 14 to unlock the building door lock (ST12: YES), the locking / unlocking unit 14 performs an unlocking step ST13 of unlocking the building door lock according to the acquired attributes of the user. After the locking / unlocking unit 14 unlocks the building door lock (after the unlocking step ST13), the communication unit 15 performs an attribute transmission step ST14 of transmitting an attribute signal Si1 including information regarding the attributes of user X1 to the communication unit 24 of the control device 2. In the attribute determination step ST15, the attribute determination unit 21 determines whether the attributes of user X1 acquired by the acquisition unit 11 of the locking / unlocking device 1 in the acquisition step ST11 match the pre-registered attributes.

[0061] When the attribute determination unit 21 determines that the attribute of user X1 acquired by the acquisition unit 11 matches the pre-registered attribute (ST15: YES), the first control step ST16 is performed to control the setting and release of the security for the building according to the attribute of user X1 (i.e., the attribute acquired by the acquisition unit 11) by causing the locking and unlocking unit 14 to unlock the door lock of the building. In the first control step ST16 of Embodiment 1, the control unit 23 maintains the state in which security is set and controls so that the unlocking of the door lock by user X1 is not detected as abnormal. More specifically, in the first control step ST16 of Embodiment 1, when the attribute determination unit 21 determines that the attribute of user X1 acquired by the acquisition unit 11 matches the pre-registered attribute, the control unit 23 maintains the security for the building in the warning mode M1 (see FIG. 2) and controls so that the unlocking of the door lock by user X1 is not detected as abnormal. After controlling so that the unlocking of the door lock by user X1 is not detected as abnormal, the control unit 23 releases the security in at least one area associated with the candidate attribute that matches the attribute of user X1 among the plurality of areas inside the building. More specifically, the control unit 23 controls so that the security for the building is shifted from the warning mode M1 to the partial warning mode M3 (see FIG. 2).

[0062] When the attribute determination unit 21 determines that the attribute of user X1 acquired by the acquisition unit 11 does not match the pre-registered attribute (ST15: NO), the control unit 23 performs a second control step ST17 of controlling the setting and release of the security for the building according to the operation of the operating device 3 by user X1. More specifically, in the second control step ST17, when the attribute determination unit 21 determines that the attribute of user X1 acquired by the acquisition unit 11 does not match the pre-registered attribute, the control unit 23 controls the setting and release of the security for the building according to the operation of the operating device 3 by user X1 (for example, a protector or co-resident who is a resident other than a child or an elderly person) who can perform the work of re-setting the security. More specifically, in the second control step ST17, the control unit 23 controls to shift the security for the building from the warning mode M1 to the warning release confirmation grace period T1 (see FIG. 2). When the control unit 23 receives a signal indicating that a person different from user X1 has selected the second operation button B2 within the warning release confirmation grace period T1, the control unit 23 shifts the security for the building from the warning release confirmation grace period T1 to the non-warning mode M2 (see FIG. 2).

[0063] (1-4) Modification Example of Embodiment 1 The above-described Embodiment 1 is merely one of various embodiments of the present disclosure. The above-described Embodiment 1 can be variously modified according to the design and the like as long as the object of the present disclosure can be achieved. For the same configuration as that of the above-described Embodiment 1, the same reference numerals are given and the description thereof is omitted.

[0064] (1-4-1) First Modification Example In the above-described Embodiment 1, when the attribute of User X1 acquired by the acquisition unit 11 matches the pre-registered attribute, the control unit 23 maintains the state in which security is set and controls so that the unlocking of the door lock by User X1 is not detected as abnormal. However, the control unit 23 of the first modification example may release the security within a preset setting time when (and when the attribute determination unit 21 determines that) the attribute of User X1 acquired by the acquisition unit 11 matches the pre-registered attribute, and reset the security after the elapse of the setting time. According to this configuration, the work of resetting the security becomes difficult or unnecessary for User X1 (for example, a child or an elderly person, etc.) who does not want to perform the work, and the convenience is improved. Further, since the unlocking of the door lock by an unexpected person (for example, a burglar) is detected as abnormal, the effect of suppressing the decrease in security can also be achieved. From the above, the security system 100 of the first modification example has the advantage that it can more surely achieve both improvement in convenience and suppression of security degradation.

[0065] When the control unit 23 of the first modification example re - sets the security after the lapse of the set time, it maintains the state in which the security in at least one area associated with the candidate attribute that matches the attribute of user X1 is released. More specifically, when the control unit 23 of the first modification example re - sets the security after the lapse of the set time, based on the table stored in the storage unit 22, among the plurality of areas inside the building, it maintains the state in which the security in at least one area associated with the candidate attribute that matches the attribute of user X1 acquired by the acquisition unit 11 is released. As an example, when the attribute of user X1 acquired by the acquisition unit 11 is "child", when the control unit 23 of the first modification example re - sets the security after the lapse of the set time, it maintains the state in which the security in the two areas respectively allocated to "living room" and "children's room" among the plurality of areas inside the building is released. According to the above configuration, the control unit 23 of the first modification example can set or release the security suitable for the attribute of user X1 who has unlocked the door lock, and has the effect of suppressing the false detection of abnormalities in the building. That is, there is an advantage that the convenience is further improved.

[0066] Specifically, when the attribute of user X1 acquired by the acquisition unit 11 matches the pre - registered attribute, the control unit 23 of the first modification example releases the warning mode M1 within the preset set time, and controls the security to shift from the warning mode M1 to a partial warning mode M3 after the lapse of the set time.

[0067] (1 - 4 - 2) Second modification example In the above-described First Embodiment, when the attribute of User X1 acquired by the acquisition unit 11 matches the pre-registered attribute, the control unit 23 maintains the security setting and controls so that unlocking of the door lock by User X1 is not detected as abnormal. However, the control unit 23 of the second modification example may release the security in at least one area associated with a candidate attribute that matches the attribute of User X1 when the attribute of User X1 acquired by the acquisition unit 11 matches the pre-registered attribute. More specifically, when the attribute determination unit 21 determines that the attribute of User X1 acquired by the acquisition unit 11 matches the pre-registered attribute, the control unit 23 of the second modification example releases the security in at least one area associated with a candidate attribute that matches the attribute of User X1 among the plurality of areas inside the building, based on the table stored in the storage unit 22. According to the above configuration, the work of re-setting the security is difficult, or the work of re-setting the security by User X1 for whom such work is not desired becomes unnecessary, and there is an effect that the convenience is improved. Further, since unlocking of the door lock by an unexpected person is detected as abnormal, there is also an effect that it is possible to suppress a decrease in security. From the above, the security system 100 of the second modification example has an advantage that it can more surely achieve both improvement in convenience and suppression of a decrease in security.

[0068] Similar to the First Embodiment described above, the storage unit 22 of the second modification example stores by associating a candidate attribute that is a candidate for the attribute of User X1 that can be acquired by the acquisition unit 11 of the locking / unlocking device 1 and at least one area among the plurality of areas inside the building. For example, different from the First Embodiment described above, in the storage unit 22 of the second modification example, two areas respectively allocated to the "entrance", "living room", and "children's room" among the plurality of areas inside the building are associated with the candidate attribute of "child". Also, two areas respectively allocated to the "entrance", "living room", and "bedroom" among the plurality of areas inside the building are associated with the candidate attribute of "elderly person".

[0069] For this reason, as an example, when the attribute of user X1 acquired by the acquisition unit 11 is "child", and when the attribute determination unit 21 determines that the attribute of user X1 acquired by the acquisition unit 11 matches the pre-registered attribute, the control unit 23 of the second modification example releases the security in the three areas respectively allocated to "entrance", "living room", and "children's room" among the plurality of areas inside the building. Also, when the attribute of user X1 acquired by the acquisition unit 11 is "elderly", and when the attribute determination unit 21 determines that the attribute of user X1 acquired by the acquisition unit 11 matches the pre-registered attribute, the control unit 23 of the second modification example releases the security in the three areas respectively allocated to "entrance", "living room", and "bedroom" among the plurality of areas inside the building.

[0070] (1-4-3) Other Modification Examples Hereinafter, modification examples of the above-described Embodiment 1 will be listed. The following modification examples may be realized in appropriate combinations. Also, functions similar to those of the security system 100 according to the above-described Embodiment 1 may be embodied by a program that is a computer program or a non-transitory recording medium on which the program is recorded. The program according to one aspect is a program for causing a computer system to execute the security method in the above-described embodiment.

[0071] In the above-described Embodiment 1, the control device 2 and the operation device 3 are separate bodies, but they may be integrated. That is, the control device 2 may have at least one of the operation unit 31 and the display unit 32.

[0072] Note that the security device 4 only needs to be configured to be able to detect the presence or absence of an abnormality in the building, and is not limited to the above-described detection sensors.

[0073] (2) Embodiment 2 (2-1) Overview Hereinafter, the security system 100a according to Embodiment 2 will be described with reference to FIGS. 4 and 5. For the same configurations as those in Embodiment 1, the same reference numerals will be given and the description thereof will be omitted.

[0074] The security system 100a according to Embodiment 2 is different from the security system 100 according to Embodiment 1 in that the control unit 23a inquires the external device A1 about a determination regarding at least one of security setting and release, and controls at least one of security setting and release based on the determination received by the external device A1.

[0075] (2-2) Detailed Configuration (2-2-1) Security System As shown in FIG. 4, the security system 100a includes a locking / unlocking device 1, a control device 2a, an operating device 3, a security device 4, a security server 5, a camera device 6, and a camera server 7. The security system 100a is configured to be communicable with an external device A1 via a network NT1.

[0076] The external device A1 is a terminal operated by a person different from the user X1. The "person different from the user X1" here means, for example, a guardian of the user X1 when the user X1 is a child, and a cohabitant of the user X1 when the user X1 is an elderly person.

[0077] The external device A1 mainly includes a computer having a CPU or MPU and a memory. In the present disclosure, it is assumed that the external device A1 is a portable terminal such as a smartphone or a tablet-type computer owned by a person different from the user X1. Note that the external device A1 may be a wearable device such as a smartwatch, or a laptop-type computer.

[0078] As shown in FIG. 4, the external device A1 includes a display unit A11, an operation unit A12, and a communication unit A13.

[0079] The display unit A11 posts information for a person different from the user X1. The display unit A11 is, for example, a liquid crystal display, an organic EL (Electro Luminescence) display, or the like. The operation unit A12 has a function of receiving operations from a person different from the user X1. In the second embodiment, the external device A1 is equipped with a touch panel display, and the touch panel display functions as the display unit A11 and the operation unit A12. However, the operation unit A12 is not limited to the touch panel display, and may be, for example, a keyboard, a pointing device, or a mechanical switch.

[0080] By being connected to the network NT1, the communication unit A13 performs two-way communication with the security system 100a via the network NT1. More specifically, the communication unit A13 performs two-way communication with the communication unit 52 of the security server 5 described later via the network NT1. In the embodiment, the communication unit A13 is connected to the network NT1 via, for example, a mobile phone network (carrier network) provided by a communication carrier or a public wireless LAN. Note that the communication unit A13 may be connected to the network NT1 via a router or the like by wireless communication using radio waves as a medium. The "wireless communication" referred to in the present disclosure is, for example, wireless communication such as Wi-Fi (registered trademark) and low-power wireless (specific low-power wireless) that does not require a license.

[0081] (2-2-2) Control device As shown in FIG. 4, the control device 2a includes an attribute determination unit 21, a storage unit 22, a control unit 23a, and a communication unit 24a.

[0082] (Control unit) The control unit 23a controls at least one of setting and releasing the security for the building. The control unit 23a in the second embodiment controls both setting and releasing the security for the building. The control unit 23a is configured to be able to communicate with the acquisition unit 11 and the unlocking unit 14 of the unlocking device 1 via the communication unit 24a and the communication unit 15 of the unlocking device 1. Also, the control unit 23a is configured to be able to communicate with the external device A1 via the communication unit 24a and the security server 5.

[0083] When the attribute of user X1 acquired by the acquisition unit 11 matches the pre-registered attribute, the control unit 23a transmits an unlocking signal Si3 indicating that the door lock has been unlocked by user X1 to the external device A1, and inquires the external device A1 about a determination regarding at least one of security setting and cancellation. The control unit 23a of the second embodiment inquires the external device A1 about a determination of a person different from user X1 regarding at least one of security setting and cancellation via the security server 5. The control unit 23a controls at least one of security setting and cancellation based on the determination of a person different from user X1 received by the external device. According to the above configuration, security can be reset based on the determination of a person different from user X1, rather than the determination of user X1 who has difficulty or does not want to perform the work of resetting security. As a result, there is an advantage that it is possible to suppress a further decrease in security.

[0084] More specifically, when the control unit 23a receives from the external device A1 via the security server 5 a signal indicating that a person different from user X1 has selected a first operation button B1 (see FIG. 5) described later, in response to the determination of setting security by a person different from user X1, the control unit 23a sets the security. Specifically, when the control unit 23a receives the unlocking signal Si3 from the communication unit 15 of the unlocking and locking device 1 via the communication unit 24a, the control unit 23a controls the security of the building to shift from the warning mode M1 (see FIG. 6) to the response time T3. When the control unit 23a receives a signal indicating that a person different from user X1 has selected the first operation button B1 within the response time T3, the control unit 23a shifts the security of the building from the response time T3 to a partial warning mode M3. The "response time T3" referred to in the present disclosure is the time for a person different from user X1 to respond to an inquiry from the control unit 23a, that is, the time for the control unit 23a to wait for a determination of a person different from user X1. The "response time T3" is the time when the security device 4 does not detect the presence or absence of an abnormality in the building, and the length of the "response time T3" is preset.

[0085] On the other hand, when the control unit 23a receives from the external device A1 via the security server 5 a signal indicating that a person different from the user X1 has selected a second operation button B2 (see FIG. 5) described later, in response to the determination that security is not set by a person different from the user X1, the control unit 23a releases the security. Specifically, when the control unit 23a receives the unlocking signal Si3 from the communication unit 15 of the unlocking and locking device 1 via the communication unit 24a, the control unit 23a controls the security for the building to shift from the warning mode M1 to the response time T3. When the control unit 23a receives within the response time T3 a signal indicating that a person different from the user X1 has selected the second operation button B2, the control unit 23a shifts the security for the building from the response time T3 to the non-warning mode M2 (see FIG. 6). Note that when the control unit 23a does not receive within the response time T3 a signal indicating that a person different from the user X1 has selected the first operation button B1 or the second operation button B2, it is desirable that the control unit 23a shifts the security for the building from the response time T3 to the partial warning mode M3.

[0086] In addition, since the control content of the control unit 23a when the attribute of the user X1 acquired by the acquisition unit 11 does not match the pre-registered attribute is the same as that of the control unit 23, the description thereof is omitted. Also, since the control content of the control unit 23a when the user X1 goes out of the building is the same as that of the control unit 23, the description thereof is omitted.

[0087] (Communication unit) The communication unit 24a is configured to be communicable with each of the communication unit 15 of the locking / unlocking device 1, the communication unit 33 of the operation device 3, and the communication unit 52 of the security server 5. The communication unit 24a in Embodiment 2 is a communication module capable of wireless communication with each of the communication unit 15 of the locking / unlocking device 1, the communication unit 33 of the operation device 3, and the communication unit 52 of the security server 5. The communication unit 24a may directly perform wireless communication with each of the communication unit 15 of the locking / unlocking device 1, the communication unit 33 of the operation device 3, and the communication unit 52 of the security server 5, or may indirectly perform wireless communication via a repeater or the like. For example, the communication unit 24a is a communication module capable of wireless communication conforming to a communication standard such as Wi-Fi (registered trademark). Note that the communication unit 24a may be a communication module capable of wired communication conforming to a communication standard such as a wired LAN.

[0088] Similar to the communication unit 24 in Embodiment 1, the communication unit 24a outputs the operation signal Si2 received from the communication unit 33 of the operation device 3 to the control unit 23a. Further, the communication unit 24a outputs the unlocking signal Si3 including information regarding the attribute of the user X1 received from the communication unit 15 of the locking / unlocking device 1 to the attribute determination unit 21.

[0089] The communication unit 24a transmits, via the communication unit 52 of the security server 5, the unlocking signal Si3 indicating that the door lock has been unlocked by the user X1 to the communication unit A13 of the external device A1. Further, the communication unit 24a receives, via the communication unit 52 of the security server 5, a signal indicating that a person different from the user X1 has selected the first operation button B1 or the second operation button B2 from the communication unit A13 of the external device A1, and outputs the signal to the control unit 23a.

[0090] (2-2-3) Security Server As shown in FIG. 4, the security server 5 includes a generation unit 51 and a communication unit 52. The security server 5 is installed outside the user's house.

[0091] (Generation Unit) The generation unit 51 generates image information Y1 and text information Y2 (see FIG. 5) to be displayed on the display unit A11 of the external device A1. Note that the dashed line frame surrounding the text information Y2 shown in FIG. 5 is a virtual frame shown for the purpose of explanation and is not the frame actually displayed by the display unit A11.

[0092] The image information Y1 is information regarding an image obtained by imaging by an imaging unit 61 of the camera device 6, which will be described later. The generation unit 51 requests an image obtained by imaging by the imaging unit 61 from the camera device 6 via the camera server 7, and generates the image information Y1 based on the image transmitted from the camera device 6 via the camera server 7.

[0093] The text information Y2 is information regarding text that asks a person different from the user X1 to make a determination regarding at least one of security setting and release. Specifically, it is information regarding the text “The child has returned home. Should the security continue?”

[0094] (Communication unit) The communication unit 52 is configured to be communicable with each of the communication unit 72 of the camera server 7 and the communication unit A13 of the external device A1 via the network NT1. In Embodiment 2, the communication unit 52 is connected to the network NT1 via, for example, wireless communication through a router or the like. Note that the communication unit 52 may be connected to the network NT1 by wire communication.

[0095] The communication unit 52 transmits a signal including the image information Y1 and the text information Y2 generated by the generation unit 51 to the communication unit A13 of the external device A1 together with the unlocking signal Si3. In other words, the unlocking signal Si3 includes an image obtained by imaging by the imaging unit 61 of the camera device 6 and text that asks a person different from the user X1 to make a determination regarding at least one of security setting and release. According to this configuration, there is an effect that a person different from the user X1 can make a determination regarding security setting and release while checking the image obtained by imaging by the imaging unit 61 of the camera device 6. As a result, there is an advantage that it is possible to more reliably suppress a decrease in security.

[0096] Based on the unlocking signal Si3, the display unit A11 of the external device A1 displays the image information Y1 and the text information Y2 as shown in FIG. 5. In the second embodiment, the display unit A11 of the external device A1 further displays the first operation button B1 and the second operation button B2 in addition to the image information Y1 and the text information Y2. As shown in FIG. 5, as an example, the text "Yes" is displayed on the first operation button B1, and the text "No" is displayed on the second operation button B2.

[0097] When it is determined that a person different from the user X1 sets the security, and the operation unit A12 receives the operation in which the person selects the first operation button B1, the communication unit A13 of the external device A1 transmits, via the security server 5, to the communication unit 24a of the control device 2a, a signal indicating that a person different from the user X1 has selected the first operation button B1.

[0098] On the other hand, when it is determined that a person different from the user X1 does not set the security, and the operation unit A12 receives the operation in which the person selects the second operation button B2, the communication unit A13 of the external device A1 transmits, via the security server 5, to the communication unit 24a of the control device 2a, a signal indicating that a person different from the user X1 has selected the second operation button B2.

[0099] (2-2-4) Camera device The camera device 6 is a device having a function of imaging the user X1. The camera device 6 of the second embodiment is a device that images the state of the user X1 returning home. As an example, the camera device 6 is installed indoors or around the user's house.

[0100] As shown in FIG. 4, the camera device 6 includes an imaging unit 61, a detection unit 62, and a communication unit 63.

[0101] (Imaging unit) The imaging unit 61 captures an image of user X1. More specifically, the imaging range of the imaging unit 61, which is the range that can be imaged, is adjusted in advance, and when user X1 enters the imaging range, the imaging unit 61 captures the imaging range including user X1. The imaging unit 61 of Embodiment 2 captures the imaging range including user X1 when the detection unit 62 detects that user X1 has entered the imaging range of the imaging unit 61.

[0102] The imaging unit 61 of Embodiment 2 acquires an image as an imaging result. Note that the "image" referred to in the present disclosure is data composed of a plurality of still images obtained by frame shooting or the like. The imaging unit 61 is configured by, for example, a camera having an imaging element and a lens. Specifically, the imaging range of the imaging unit 61 of Embodiment 2 is adjusted so that the state of user X1 returning home can be imaged.

[0103] (Communication unit) The communication unit 63 is configured to be communicable with a communication unit 72 of a camera server 7 described later. The communication unit 63 of Embodiment 2 is a communication module capable of wireless communication with the communication unit 72 of the camera server 7. The communication unit 63 may directly perform wireless communication with the communication unit 72 of the camera server 7, or may indirectly perform wireless communication via a repeater or the like. For example, the communication unit 63 is a communication module capable of wireless communication compliant with a communication standard such as Wi-Fi (registered trademark). Note that the communication unit 15 may be a communication module capable of wired communication compliant with a communication standard such as a wired LAN.

[0104] The communication unit 63 transmits the image obtained by the imaging unit 61 to the communication unit 72 of the camera server 7.

[0105] (2-2-5) Camera server As shown in FIG. 4, the camera server 7 includes a storage unit 71 and a communication unit 72. The camera server 7 is installed outside the user's house.

[0106] (Storage unit) The storage unit 71 stores the image transmitted from the communication unit 63 of the camera device 6. In short, the storage unit 71 stores the image obtained by the imaging unit 61.

[0107] The storage unit 71 includes a rewritable non-volatile memory such as an EEPROM, for example.

[0108] (Communication unit) The communication unit 72 is configured to be communicable with each of the communication unit 52 of the security server 5 and the communication unit A13 of the external device A1 via the network NT1. In the second embodiment, the communication unit 72 is connected to the network NT1 via a router or the like by wireless communication, for example. Note that the communication unit 72 may be connected to the network NT1 by wired communication.

[0109] The communication unit 72 transmits the image stored in the storage unit 71 to the communication unit 52 of the security server 5 in response to a request from the generation unit 51 of the security server 5.

[0110] (2-3) Security method When the door lock of the building is about to be unlocked by the user X1, the security method in which the security system 100a of the second embodiment monitors the presence or absence of an abnormality in the building will be described using the flowchart of FIG. 7.

[0111] As shown in FIG. 7, the security method of the second embodiment includes an acquisition step ST21, an unlocking determination step ST22, an unlocking step ST23, an attribute transmission step ST24, an attribute determination step ST25, an inquiry step ST26, a first control step ST27, and a second control step ST28. The first control step ST27 corresponds to the control step of the present invention.

[0112] Note that since the acquisition step ST21, unlocking determination step ST22, unlocking step ST23, attribute transmission step ST24, and attribute determination step ST25 in the security method of Embodiment 2 are the same as the acquisition step ST11, unlocking determination step ST12, unlocking step ST13, attribute transmission step ST14, and attribute determination step ST15 in the security method of Embodiment 1, detailed descriptions thereof are omitted.

[0113] When the attribute determination unit 21 determines that the attribute of user X1 acquired by the acquisition unit 11 matches the pre-registered attribute (ST25: YES), the control unit 23a transmits an unlocking signal Si3 indicating that the door lock has been unlocked by user X1 to the external device A1 via the security server 5, and performs an inquiry step ST26 of inquiring the external device A1 about a determination regarding at least one of security setting and cancellation. In the security server 5, the generation unit 51 generates image information Y1 and text information Y2 (see FIG. 5) to be displayed on the display unit A11 of the external device A1, and the communication unit 52 transmits a signal including the image information Y1 and the text information Y2 generated by the generation unit 51 to the communication unit A13 of the external device A1 together with the unlocking signal Si3.

[0114] Then, in the first control step ST27, the control unit 23a controls at least one of security setting and cancellation based on a determination of a person different from user X1 received by the external device. More specifically, when the control unit 23a receives from the external device A1 via the security server 5 a signal indicating that a person different from user X1 has selected the first operation button B1 (see FIG. 5), the control unit 23a sets the security according to a determination to set the security by a person different from user X1. On the other hand, when the control unit 23a receives from the external device A1 via the security server 5 a signal indicating that a person different from user X1 has selected the second operation button B2 (see FIG. 5), the control unit 23a cancels the security according to a determination not to set the security by a person different from user X1.

[0115] When the attribute determination unit 21 determines that the attribute of user X1 acquired by the acquisition unit 11 does not match the pre-registered attribute (ST25: NO), the control unit 23a performs a second control step ST28 of controlling the setting and release of security for the building according to the operation of the operation device 3 by user X1. Since the second control step ST28 is the same as the second control step ST17 in the security method of the first embodiment, detailed description thereof is omitted.

[0116] (2-4) Modification Example of Embodiment 2 The above-described Embodiment 2 is merely one of various embodiments of the present disclosure. The above-described Embodiment 2 can be variously modified according to design and the like as long as the object of the present disclosure can be achieved. The following modification examples may be realized in appropriate combinations.
