[0007] [Figure 1] 1 is a block diagram showing the overall configuration of an in-home / out-home determination device A. FIG. [Figure 2]3 is a block diagram showing the functional configuration of a relay device 4. FIG. [Figure 3] 10 is a flowchart showing the operation of the coming-home / going-out determination device A. DETAILED DESCRIPTION OF THE INVENTION

[0008] As shown in FIG. 1, the home / away determination device A according to this embodiment includes an electric lock 1, a mobile terminal 2 ( Electric lock The components of the system are an operation terminal, a smart home appliance 3, a relay device 4 (determination device), and a wireless LAN router 5. LAN is an abbreviation for Local Area Network.

[0009] Among the components of the home / away determination device A, the electric lock 1, the mobile terminal 2, and the relay device 4 are called a "smart lock." The electric lock 1 is locked and unlocked by the mobile terminal 2 ( Electric lock It comprises a contactless locking and unlocking system operated from an operation terminal.

[0010] The electric lock 1 is installed at an entrance such as a front door in a building such as a typical house. The electric lock 1 is a lock that can be locked and unlocked electrically and can perform short-range communication with a mobile terminal 2 and a relay device 4. The short-range communication method (communication standard) used in this embodiment is so-called "Bluetooth (registered trademark)." The electric lock 1 performs wireless communication (Bluetooth communication) with the mobile terminal 2 and the relay device 4 in accordance with the Bluetooth communication protocol.

[0011] In addition to "Bluetooth (registered trademark)," several other methods (communication standards) for short-range communication are generally known, such as "ZigBee (registered trademark)." In this embodiment, "Bluetooth (registered trademark)" is used as the short-range communication method, but the coming-home / going-out determination device A may be constructed by using other short-range communication methods as needed.

[0012] When the electric lock 1 receives a locking instruction from the mobile terminal 2, it enters a locked state (a state in which the entrance cannot be opened or closed) based on the locking instruction. When the electric lock 1 receives an unlocking instruction from the mobile terminal 2, it enters an unlocked state (a state in which the entrance can be opened or closed freely) based on the unlocking instruction. The electric lock 1 notifies the relay device 3 of the locked or unlocked state based on the locking or unlocking instruction received from the mobile terminal 2.

[0013] The mobile terminal 2 is a mobile device that can be carried by a human user, such as a smartphone. The mobile terminal 2 is a communication device that can communicate with the electric lock 1 via Bluetooth. The mobile terminal 2 includes an application program ( Electric lock control program) is pre-installed.

[0014] The mobile terminal 2 transmits a locking instruction or an unlocking instruction to the electric lock 1 via short-range communication based on the electronic lock control program, thereby locking or unlocking the electric lock 1. Electric lock The electronic lock control program is compatible with the OS (Operating System) of the mobile terminal 2.

[0015] When the user returns home from outside, the user approaches the entrance of the building and Electric lock By operating the control program, an unlock instruction is sent to the electric lock 1. When the electric lock 1 receives the unlock instruction from the mobile terminal 2, it makes the entrance open and close freely (unlocked state) according to the unlock instruction.

[0016] When the user goes out of the building, the user accesses the mobile terminal 2 from outside the entrance (outside the building). Electric lock By operating the control program, a locking instruction is sent to the electric lock 1. When the electric lock 1 receives the locking instruction from the mobile terminal 2, it disables the entrance and exit from being opened or closed (locked state) in accordance with the locking instruction.

[0017] The smart home appliances 3 are home appliances that can connect to external communication terminals and are components of a home network (home LAN) established in a building. In this embodiment, a home network including the smart home appliances 3 and the wireless LAN router 5 as components is established in advance in the building.

[0018] The smart home appliance 3 is, for example, an outlet or light with a communication function, commonly called a smart outlet (smart plug) or smart lighting. The smart home appliance 3 performs wireless communication (wireless LAN communication) with the wireless LAN router 5 using a communication protocol that complies with wireless LAN (Local Area Network), a communication method (communication standard) that has a longer communication distance than short-range communication.

[0019] The smart home appliances 3 perform their functions based on operation instructions received from the outside via the wireless LAN router 5. For example, a smart outlet (smart plug) starts supplying power to the electrical devices connected to it when it receives a power-on instruction from the outside. A smart light switches from an off state to an on state when it receives a power-on instruction from the outside.

[0020] The relay device 4 is installed near the entrance (entrance floor) inside the building. The relay device 4 is a communication device that relays wireless communication between the electric lock 1 and the home network (home LAN). The relay device 4 communicates with the electric lock 1 via Bluetooth, but also communicates with the smart home appliances 3 and the wireless LAN router 5 via a communication method (communication standard) that has a longer communication distance than Bluetooth communication.

[0021] The communication method between the relay device 4, the smart home appliances 3, and the wireless LAN router 5 is a wireless LAN that is generally called "Wi-Fi (registered trademark)" and conforms to a home network (domestic LAN).

[0022] The relay device 4 is equipped with a human sensor 4a as shown in Figure 1, and in addition to the human sensor 4a, is equipped with a pairing switch 4b, a power LED 4c, a power plug 4d, a power circuit 4e, a memory 4f, an MCU 4g, a smart lock communication circuit 4h, a smart lock high-frequency circuit 4i, a smart lock antenna 4j, a home network communication circuit 4k, a home network high-frequency circuit 4m, and a home network antenna 4n as shown in Figure 2.

[0023] The human presence sensor 4a is provided near the entrance (inside the entrance) in the relay device 4, i.e., in the building. The human presence sensor 4a is, for example, an infrared sensor that detects infrared rays emitted by a user (person) and detects the presence of a user (person) near the entrance. When the human presence sensor 4a detects a user (person) inside the entrance, it outputs a detection signal (detection result) indicating that the presence of the user (person) has been detected to the MCU 4g.

[0024] The pairing switch 4b is an operation button that instructs the MCU 4g to pair with the electric lock 1. When a user operates the pairing switch 4b, the pairing switch 4b outputs a pairing start signal to the MCU 4g. The MCU 4g establishes pairing with the electric lock 1 based on the pairing start signal.

[0025] In detail, the MCU 4g establishes a communication line with the electric lock 1 by performing short-distance communication with the electric lock 1 via the smart lock communication circuit 4h, the smart lock high-frequency circuit 4i, and the smart lock antenna 4j. When pairing is established between the electric lock 1 and the relay device 4, the electric lock 1 and the relay device 4 are able to freely communicate with each other in short distances.

[0026] The power LED 4c is a semiconductor light-emitting element (light-emitting diode) that notifies the outside world that power is being supplied to the relay device 4. The power LED 4c emits light in accordance with a light-emitting signal input from the MCU 4g when power is being supplied to the relay device 4. The light-emitting signal is a voltage signal having a voltage that can cause the power LED 4c, which is a semiconductor light-emitting element, to emit light.

[0027] The power plug 4d is a connecting part that connects the relay device 4 to a commercial power source (AC power source) such as AC 100V installed in a building. As is well known, the power plug 4d has a pair of electrodes, and the pair of electrodes is connected to the commercial power source and the power plug 4d connects the relay device 4 to the commercial power source by engaging with an outlet that also has a pair of electrodes. When the power plug 4d is engaged with the outlet, commercial power is supplied to the relay device 4.

[0028] The power supply circuit 4e is a power conversion circuit that converts commercial power (AC power) input from the power plug 4d into DC power. The power supply circuit 4e converts the commercial power (AC power) into DC power that is used by various electronic components (the human sensor 4a, the pairing switch 4b, and the power LED 4c) and various electronic circuits (the memory 4f, the MCU 4g, the smart lock communication circuit 4h, the smart lock high-frequency circuit 4i, the home network communication circuit 4k, and the home network high-frequency circuit 4m) of the relay device 4.

[0029] The various electronic components (the motion sensor 4a, the pairing switch 4b, and the power LED 4c) perform their desired functions based on the DC power supplied from the power supply circuit 4e. The various electronic circuits, such as the memory 4f and the MCU 4g, also perform their desired functions based on the DC power supplied from the power supply circuit 4e.

[0030] The memory 4f is a semiconductor storage device that stores the relay program executed by the MCU 4g and various control data required for executing the relay program. The memory 4f is composed of a non-volatile memory (ROM: Read Only Memory) and a volatile memory (RAM: Random Access Memory).

[0031] The memory 4f stores the relay program and various control data in a non-volatile memory, and stores data generated by the MCU 4g in the process of executing the relay program in a volatile memory. Reading and writing of data in the memory 4f is controlled by the MCU 4g that executes the relay program.

[0032] The MCU 4g is a control unit (microcontroller unit) of the relay device 4 that performs overall control of the relay device 4. The MCU 4g includes a central processing unit (CPU) that executes a relay program, a human sensor 4a, a pairing switch 4b, a power LED 4c, a memory 4f, an input / output unit that inputs and outputs data to and from the smart lock communication circuit 4h and the home network communication circuit 4k, and the like.

[0033] The MCU 4g receives a detection signal input from the human sensor 4a based on the relay program. The MCU 4g receives a pairing start signal input from the pairing switch 4b based on the relay program. The MCU 4g outputs a light-emitting signal to the power LED 4c based on the relay program.

[0034] The MCU 4g outputs a transmission instruction (Bluetooth communication instruction) to the smart lock communication circuit 4h based on the relay program, thereby performing Bluetooth communication with the electric lock 1 via the smart lock high-frequency circuit 4i and the smart lock antenna 4j.

[0035] The MCU 4g outputs a transmission instruction (wireless LAN communication instruction) to the home network communication circuit 4k based on the relay program, thereby performing wireless LAN communication with the wireless LAN router 5 via the home network high frequency circuit 4m and the home network antenna 4n. Detailed processing of the MCU 4g will be described later as the operation of the coming-home / going-out determination device A according to this embodiment.

[0036] The smart lock communication circuit 4h generates a communication packet (Bluetooth transmission packet) conforming to the Bluetooth communication protocol based on the Bluetooth transmission instruction input from the MCU 4g and outputs it to the smart lock high frequency circuit 4i. The Bluetooth transmission packet includes at least the identification number of the relay device 4 as the sender, the identification number of the electric lock 1 as the destination, and transmission data indicating the transmission content.

[0037] The smart lock communication circuit 4h extracts the received data from the electric lock 1 based on the Bluetooth received packet input from the smart lock high frequency circuit 4i. The Bluetooth received packet contains at least the identification number of the electric lock 1 as the sender, the identification number of the relay device 4 as the destination, and received data indicating the received content. The smart lock communication circuit 4h outputs the received data to the MCU 4g.

[0038] The smart lock high frequency circuit 4i is a high frequency circuit that performs high frequency transmission processing (Bluetooth high frequency transmission processing) conforming to the Bluetooth communication protocol on the Bluetooth transmission packets input from the smart lock communication circuit 4h. The Bluetooth high frequency transmission processing is a modulation processing conforming to the Bluetooth communication protocol, and converts the Bluetooth transmission packets into Bluetooth high frequency transmission signals. The smart lock high frequency circuit 4i outputs the Bluetooth high frequency transmission signals to the smart lock antenna 4j.

[0039] The smart lock high frequency circuit 4i extracts a Bluetooth reception packet from the Bluetooth high frequency reception signal by performing high frequency reception processing (Bluetooth high frequency reception processing) that conforms to the Bluetooth communication protocol on the Bluetooth high frequency reception signal input from the smart lock antenna 4j. The Bluetooth high frequency reception processing is a demodulation process that conforms to the Bluetooth communication protocol. The smart lock high frequency circuit 4i outputs the Bluetooth reception packet to the smart lock communication circuit 4h.

[0040] The smart lock antenna 4j is a high-frequency component that radiates the Bluetooth high-frequency transmission signal input from the smart lock high-frequency circuit 4i into the air as radio waves (Bluetooth transmission waves). The Bluetooth transmission waves are high-frequency waves in the 2.4 GHz band that contain the contents of a Bluetooth transmission packet, and when received by the electric lock 1, the destination, the contents of the Bluetooth transmission packet are reproduced.

[0041] The smart lock antenna 4j converts radio waves (Bluetooth reception waves) received from the air into Bluetooth high-frequency reception signals and outputs them to the smart lock high-frequency circuit 4i. The Bluetooth reception waves are high-frequency waves in the 2.4 GHz band that contain the contents of a Bluetooth reception packet, and are transmitted from the electric lock 1, which is the source of the transmission. The Bluetooth reception packet is a Bluetooth transmission packet generated by the electric lock 1.

[0042] The home network communication circuit 4k generates a communication packet (wireless LAN transmission packet) conforming to the wireless LAN communication protocol based on the wireless LAN transmission instruction input from the MCU 4g and outputs it to the home network high frequency circuit 4m. The wireless LAN transmission packet includes at least the identification number of the relay device 4 as the sender, the identification number of the wireless LAN router 5 as the destination, and transmission data indicating the transmission content.

[0043] The home network communication circuit 4k extracts the received data from the electric lock 1 based on the wireless LAN received packet input from the home network high frequency circuit 4m. The Bluetooth received packet contains at least the identification number of the wireless LAN router 5 as the sender, the identification number of the relay device 4 as the destination, and received data indicating the received content.

The wireless LAN high frequency reception processing is a demodulation process that conforms to the wireless LAN communication protocol.

[0046] The home network antenna 4n is a high-frequency component that radiates the wireless LAN high-frequency transmission signal input from the home network high-frequency circuit 4m into the air as radio waves (wireless LAN transmission waves). The wireless LAN transmission waves are high-frequency waves in the 2.4 GHz band that contain the contents of the wireless LAN transmission packets, and when they are received by the wireless LAN router 5, which is the destination, the contents of the wireless LAN transmission packets are reproduced.

[0047] The home network antenna 4n converts radio waves (wireless LAN reception waves) received from the air into wireless LAN high-frequency reception signals and outputs them to the home network high-frequency circuit 4m. The wireless LAN reception waves are high-frequency waves in the 2.4 GHz band that contain the contents of wireless LAN reception packets and are transmitted from the wireless LAN router 5, which is the source of the transmission. The wireless LAN reception packets are wireless LAN transmission packets generated by the wireless LAN router 5.

[0048] The wireless LAN router 5 is a communication device (connection device) that connects a home network (domestic LAN) to an external communication line such as the Internet. The wireless LAN router 5 performs wireless LAN communication with the smart home appliances 3 and the relay device 4 in accordance with the wireless LAN communication protocol, and also performs communication with the external communication line in accordance with the communication protocol of the external communication line.

[0049] The wireless LAN router 5 receives operation instructions (external operation instructions) from the smart home appliances 3 via, for example, an external communication line. The wireless LAN router 5 converts the external operation instructions into wireless LAN transmission waves that comply with the wireless LAN communication protocol and transmits them to the smart home appliances 3. The smart home appliances 3 operate according to the external operation instructions.

[0050] The wireless LAN router 5 receives, as a wireless LAN received wave, a wireless LAN transmission wave including transmission data indicating the operating status of the electric lock 1 and information on whether the user has come home or gone out, for example, from the relay device 4. The wireless LAN router 5 extracts the received data (transmission data of the wireless LAN transmission wave) from the wireless LAN received wave and saves the operating status of the electric lock 1 and the information on whether the user has come home or gone out as log information.

[0051] The wireless LAN router 5 transmits the log information to the cloud B as needed. The cloud B is a storage device provided on an external communication line. The cloud B stores the log information received from the wireless LAN router 5.

[0052] The operation of the coming-home / going-out determination device A according to this embodiment will be described with reference to the flowchart shown in FIG.

[0053] First, we will explain what happens when a user returns home from an outing. The electric lock 1 and the MCU 4g of the relay device 4 are constantly monitoring for the occurrence of an event. When the user returns home from an outing, they input an instruction to unlock the electric lock 1 into the mobile terminal 2 in front of the entrance (outside the entrance). The mobile terminal 2 sends the user's instruction to unlock the electric lock 1 via Bluetooth communication.

[0054] When the electric lock 1 receives an "unlock instruction" from the mobile terminal 2 (step S1), it changes itself from a locked state to an unlocked state in accordance with the unlock instruction (event) (step S2). After setting itself to the unlocked state, the electric lock 1 notifies the relay device 4 of an unlock notification via Bluetooth communication (step S3).

[0055] When the electric lock 1 is unlocked, the user moves from the entrance to the entrance floor inside the building (inside the entrance). When the human presence sensor 4a of the relay device 4 detects a user on the entrance floor, it outputs a detection signal to the MCU 4g. When the MCU 4g detects the detection signal as an event (step S7), it evaluates the order of unlocking the electric lock 1 and detecting the person (step S8).

[0056] In the current state, the human sensor 4a detects a person (user) after the electric lock 1 is unlocked, so the evaluation result of step S8 is "A." When the evaluation result of step S8 becomes "A," the MCU 4g determines that the user has returned home (step S9). The MCU 4g transmits the fact that the user has returned home as log information to cloud B (step S12).

[0057] Next, a case where the user goes out will be described. When the user goes out, the user on the entrance floor is detected by the human presence sensor 4a. When the human presence sensor 4a detects the user, it outputs a detection signal to the MCU 4g. The MCU 4g detects the detection signal as an event (step S7).

[0058] The user then moves from the entrance floor to outside the entrance and inputs a locking instruction to the mobile terminal 2 outside the entrance to lock the electric lock 1. The mobile terminal 2 transmits the user's locking instruction to the electric lock 1 via Bluetooth communication. When the electric lock 1 receives the "locking instruction" from the mobile terminal 2 (step S4), it sets itself from an unlocked state to a locked state in accordance with the locking instruction (event) (step S5). When the electric lock 1 sets itself to the locked state, it notifies the relay device 4 of a locking notification via Bluetooth communication (step S6).

[0059] When the locking notification is input from the high-frequency circuit for smart lock 4i, the MCU 4g evaluates the order of human detection and locking of the electric lock 1 (step S8). In this state, the electric lock 1 was locked after the human sensor 4a detected a person (user), so the evaluation result of step S8 is "B."

[0060] When the evaluation result in step S8 becomes "B", the MCU 4g determines that the user has gone out (step S10). The MCU 4g transmits the fact that the user has gone out as log information to the cloud B (step S12).

[0061] If the electric lock 1 is not locked after the human sensor 4a detects a person (user), the MCU 4g sets the evaluation result of step S8 to "C." In this case, the MCU 4g does not determine that the user has gone out, but sets the result to "no determination," and goes into a state of monitoring the occurrence of the next event.

[0062] In cloud B, the return or departure of users from the building is accumulated as chronological log information based on the operation of the return / departure determination device A shown in Fig. 3. The log information in cloud B can be viewed by anyone with viewing authority. By viewing this information, anyone with viewing authority can easily confirm whether users have returned or left the building.

[0063] According to this embodiment, a simple configuration in which a human presence sensor 4a is provided in the relay device 4 that constitutes the smart lock allows the system to automatically and inexpensively determine whether the user is at home or out. Return home It is possible to provide an out-of-home determination device A.

[0064] The present disclosure is not limited to the above-described embodiment, and various modifications are possible.

[0065] (1) The unlocked state in step S2 is not limited to the unlock instruction in step S1. The locked state in step S5 is not limited to the lock instruction in step S4. Since electric locks 1 are generally provided with a manual operation function, the setting may be changed from the locked state to the unlocked state by manual operation by the user, or from the unlocked state to the locked state by manual operation by the user.

[0066] (2) In the present embodiment, the human presence sensor 4a is provided in the relay device 4, but the present disclosure is not limited to this. The human presence sensor 4a may be provided in the building near an entrance or exit, and may be provided separately from the relay device 4.

[0067] (3) In this embodiment, Bluetooth (registered trademark) is used as the short-range communication method, but the present disclosure is not limited to this. For example, ZigBee (registered trademark) may be used as a short-range communication method other than Bluetooth.

[0068] (4) In this embodiment, the log information is stored in cloud B, but the present disclosure is not limited to this. The log information may be stored in a storage device other than cloud B that is communicable therewith. [Explanation of symbols]
