Summary of the Invention

Problems to be Solved by the Invention

[0004] The security system described in Patent Document 1 releases the alert mode (security) based on the unlocking of the door lock, and automatically resets the alert mode on the condition that the door has not been opened after the release of the alert mode. In this case, although the resetting of the alert mode becomes unnecessary, it is conceivable that when an unexpected person unlocks the door lock, the alert mode is released and then the alert mode is reset. That is, there is a possibility that the security will deteriorate. Therefore, in the security system described in Patent Document 1, there may be a case where it is impossible to achieve both an improvement in convenience and a suppression of a decrease in security.

[0005] An object of the present disclosure is to provide a security system, a security method, and a program that can achieve both an improvement in convenience and a suppression of a decrease in security.

Means for Solving the Problems

[0006] A security system according to an aspect of the present disclosure includes a positioning unit, an estimation unit, and a control unit. The positioning unit is installed inside a building and measures the position of a user based on a signal transmitted from a user terminal owned by the user moving inside the building. The estimation unit estimates the moving direction of the user based on the positioning result of the positioning unit. The control unit controls the setting or release of the security for the building based on the moving direction of the user, or notifies the user of recommendation information for recommending the setting or release of the security.

[0007] A security method according to an aspect of the present disclosure includes a positioning step, an estimation step, and a control step. In the positioning step, the position of a user is measured based on a signal transmitted from a user terminal owned by the user moving inside a building. In the estimation step, the moving direction of the user is estimated based on the positioning result in the positioning step. In the control step, based on the moving direction of the user, the security setting for the building is controlled to be set or released, or recommendation information for recommending the setting or release of the security is notified to the user.

[0008] A program according to an aspect of the present disclosure is a program for causing a computer system to execute the above security method.

Mode for Carrying Out the Invention

[0011] (Embodiment) (1) Outline Hereinafter, the outline of the security system 100 according to the present embodiment will be described with reference to FIGS. 1 to 3.

[0012] The security system 100 according to the present embodiment is used for a building Y1 (see FIG. 2) such as a detached house, and is a system that monitors the presence or absence of abnormalities in the building Y1. Note that the building Y1 in which the security system 100 of the present embodiment is used is not limited to a detached house, and may be a dwelling unit in an apartment building. In the following embodiments, a detached house will be described as an example.

[0013] As shown in FIG. 1, the security system 100 of the present embodiment includes a positioning unit 11, an estimation unit 12, and a control unit 21. The positioning unit 11 is installed inside the building Y1 and measures the position of the user X1 based on a signal transmitted from the user terminal X2 owned by the user X1 moving inside the building Y1. The estimation unit 12 estimates the moving direction D1 (see FIGS. 2 and 3) of the user X1 based on the positioning result of the positioning unit 11. The control unit 21 controls the setting or release of security for the building Y1 based on the moving direction D1 of the user X1, or notifies the user X1 of recommendation information for recommending the setting or release of security. Note that the "security setting" as used in the present disclosure means setting to monitor the presence or absence of abnormalities in the building Y1 in which the security system 100 is used, and the "security release" means setting not to monitor the presence or absence of abnormalities in the building Y1 in which the security system 100 is used.

[0014] As described above, in the security system 100 of the present embodiment, when the control unit 21 controls the setting or cancellation of security based on the moving direction D1 of the user X1, it becomes unnecessary for the user X1 to set or cancel the security. Further, in the security system 100 of the present embodiment, when the control unit 21 notifies the user X1 of recommendation information for recommending the setting or cancellation of security based on the moving direction D1 of the user X1, it is possible to suppress the user X1 from forgetting to set or cancel the security. In short, the security system 100 of the present embodiment has the effect of improving the convenience of the user X1. Furthermore, in the security system 100 of the present embodiment, when an unexpected person (for example, a burglar) unlocks the door lock and moves inside the building Y1, since the control unit 21 does not control the setting or cancellation of security, there is also an effect that it is possible to suppress a decrease in security. From the above, the security system 100 of the present embodiment has the advantage that it can achieve both an improvement in convenience and a suppression of a decrease in security.

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

[0016] The security system 100 is a system for monitoring the presence or absence of abnormalities in the building Y1. In other words, the security system 100 is a system that provides security for the building Y1.

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

[0018] (2-2) Operation Device The operating device 1 is a device that receives the operations of user X1 for setting or releasing security. As shown in FIGS. 2 and 3, the operating device 1 is installed inside the building Y1. The operating device 1 is installed, for example, at a location close to the door Y2 of the building Y1 where a door lock is provided (for example, the entrance or the corridor).

[0019] As shown in FIG. 1, the operating device 1 includes a positioning unit 11, an estimation unit 12, an operation unit 13, a display unit 14, and a communication unit 15.

[0020] The operating device 1 preferably includes a computer system. In the computer system, a processor such as a CPU (Central Processing Unit) or an MPU (Micro Processing Unit) reads and executes a program stored in a memory, thereby realizing some or all of the functions of the estimation unit 12. 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 a plurality of 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 called a system LSI, a VLSI (Very Large Scale Integration), or a ULSI (Ultra Large Scale Integration). A field programmable gate array (FPGA), or a reconfigurable logic device capable of reconfiguring the bonding relationship inside the LSI or setting up the circuit sections inside the LSI, which is programmed after the manufacture of 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 integrated into one device or provided in a plurality of devices.

[0021] (Positioning unit) The positioning unit 11 is installed inside the building Y1 and measures the position of the user X1 based on the signal transmitted from the user terminal X2 owned by the user X1 moving inside the building Y1. The positioning unit 11 of the present embodiment measures the position of the user X1 based on the identification signal transmitted from the user terminal X2 of the user X1 moving inside the building Y1. More specifically, the positioning unit 11 of the present embodiment measures the position of the user terminal X2 that transmitted the identification signal as the position of the user X1 based on the identification signal transmitted from the user terminal X2. As an example, the positioning unit 11 has a plurality of receivers that receive the identification signal transmitted from the user terminal X2, and calculates the angle at which the signal reaches the positioning unit 11 from the user terminal X2 based on the phase difference of the identification signal in the plurality of receivers, thereby measuring the position of the user terminal X2. Further, the positioning unit 11 may measure the position of the user terminal X2 based on the difference in arrival times of the identification signal in the plurality of receivers. Note that the positioning unit 11 may measure the position of the user terminal X2 based on the signal strength of the identification signal in the plurality of receivers. That is, the method by which the positioning unit 11 measures the position of the user X1 is not limited. Also, the "identification information" referred to here is information that is pre-associated one-to-one with each user terminal X2. In the present disclosure, the user terminal X2 is assumed to be a smartphone or a tablet computer owned by the user X1. Note that the user terminal X2 may be a dedicated terminal (for example, a remote control key, etc.) for use in the security system 100.

[0022] The positioning unit 11 of the present embodiment is a high-precision positioning module having a positioning accuracy of 1 m or less. As an example, the positioning unit 11 of the present embodiment is a high-precision positioning module using ultra-wideband radio (UWB: Ultra-Wide Band) or the like. According to this configuration, there is an advantage that the estimation unit 12 can estimate the moving direction D1 of the user X1 with higher accuracy. Note that the "positioning accuracy" referred to in the present disclosure is the degree of accuracy when measuring the position of the user X1, and indicates the measurement error assumed when measuring the user X1. The smaller the positioning accuracy, the higher the accuracy with which the positioning unit 11 can measure the position of the user X1.

[0023] (Estimation Unit) Based on the positioning result of the positioning unit 11 (i.e., the measured position of user X1), the estimation unit 12 estimates the moving direction D1 (Figs. 2 and 3) of user X1. More specifically, the estimation unit 12 estimates the moving direction D1 of user X1 based on the difference between the position of user X1 detected by the positioning unit 11 before a predetermined time has elapsed and the position of user X1 detected by the positioning unit 11 after the predetermined time has elapsed.

[0024] Specifically, the case where user X1 returns home to building Y1 (see Fig. 2) will be described. In the above case, the estimation unit 12 estimates the moving direction D11 of user X1 based on the difference between the position of user X11 detected by the positioning unit 11 before a predetermined time has elapsed and the position of user X12 detected by the positioning unit 11 after the predetermined time has elapsed. In the example shown in Fig. 2, "user X11 detected by the positioning unit 11 before a predetermined time has elapsed" is user X1 who unlocked the door lock and entered the entrance or corridor from the entrance of building Y1. On the other hand, "user X12 detected by the positioning unit 11 after the predetermined time has elapsed" is user X1 who has moved from the entrance or corridor of building Y1 to the living room. Therefore, the moving direction D11 when user X1 returns home to building Y1 is the direction from the entrance or corridor to the living room in building Y1.

[0025] Next, assuming that user X1 goes out of building Y1 (see Fig. 3), an explanation will be given. When user X1 goes out of building Y1, the estimation unit 12 estimates the moving direction D12 of user X1 based on the difference between the position of user X13 detected by the positioning unit 11 before a predetermined time has elapsed and the position of user X14 detected by the positioning unit 11 after the predetermined time has elapsed. In the example shown in Fig. 3, "user X13 detected by the positioning unit 11 before a predetermined time has elapsed" is user X1 who is about to move from the living room of building Y1 to the entrance or corridor. On the other hand, "user X14 detected by the positioning unit 11 after the predetermined time has elapsed" is user X1 who is about to go out from the entrance or corridor of building Y1. Therefore, the moving direction D12 when user X1 goes out of building Y1 is the direction from the living room to the entrance or corridor in building Y1. In short, the moving direction D11 when user X1 returns home to building Y1 and the moving direction D12 when user X1 goes out of building Y1 are different directions.

[0026] The estimation unit 12 of the present embodiment estimates the moving direction D1 of user X1 in the horizontal direction based on the positioning result of the positioning unit 11. According to this configuration, there is an advantage that the difference between the moving direction D11 when user X1 returns home to building Y1 and the moving direction D12 when user X1 goes out of building Y1 becomes clear.

[0027] (Operation unit) The operation unit 13 receives the operation of user X1 for setting or canceling security. The operation unit 13 receives the operation for canceling security after user X1 unlocks the door lock and returns home to building Y1. Also, the operation unit 13 receives the operation for setting security when user X1 goes out of building Y1.

[0028] (Display unit) The display unit 14 displays the security setting state. More specifically, the display unit 14 displays whether security is set or released. More specifically, the display unit 14 is a plurality of light-emitting elements corresponding to each of the states of whether security is set or released, and causes the light-emitting element corresponding to the current state of security among the plurality of light-emitting elements to emit light.

[0029] (Communication unit) The communication unit 15 is configured to be communicable with a communication unit 25 of the control device 2 described later. The communication unit 15 of the present embodiment is a communication module capable of wired communication conforming to a communication standard such as a wired LAN with the communication unit 25 of the control device 2. Note that the communication unit 15 may be a communication module capable of wireless communication. In this case, the communication unit 15 may perform direct wireless communication with the communication unit 25, or may perform indirect 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).

[0030] The communication unit 15 transmits a movement direction signal including information regarding the movement direction D1 of the user X1 estimated by the estimation unit 12 to the communication unit 25 of the control device 2. In addition, the communication unit 15 transmits an operation signal indicating that an operation of the user X1 for setting or releasing security has been received to the communication unit 25 of the control device 2.

[0031] (2-3) Control device The control device 2 is a device that controls at least one of setting and releasing security for the building Y1. That is, the control device 2 is a device that controls a security device 4 described later. The control device 2 of the present embodiment controls both setting and releasing security for the building Y1.

[0032] As shown in FIG. 1, the control device 2 includes a control unit 21, a user determination unit 22, a detection unit 23, a number determination unit 24, and a communication unit 25. The user determination unit 22 corresponds to the determination unit of the present disclosure.

[0033] The control device 2 preferably includes a computer system. In the computer system, each function of the control unit 21, the user determination unit 22, and the number determination unit 24 is realized by a processor such as a CPU or an MPU 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. 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, or a ULSI. 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 the 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.

[0034] (Control Unit) The control unit 21 controls the processing related to the security of the building Y1. As shown in FIG. 1, the control unit 21 includes a function control unit 211, a notification unit 212, and an output unit 213.

[0035] The function control unit 211 controls the setting and release of the security for the building Y1. That is, the function control unit 211 has a security setting function and a release function for the building Y1. Note that the function control unit 211 of the present embodiment determines whether the security for the building Y1 is set.

[0036] When the function control unit 211 is in a state where it can set security, it controls the security setting for building Y1. More specifically, when the function control unit 211 determines that it is in a state where it can set security, the function control unit 211 controls the security setting for building Y1.

[0037] On the other hand, when the function control unit 211 determines that it is in a state where it cannot set security, the output unit 213 outputs factor information including the factor that security cannot be set to the user terminal X2. In short, when in a state where security cannot be set, the output unit 213 outputs factor information including the factor that security cannot be set to the user terminal X2. As an example, the factor information in the case where security cannot be set due to the factor that there is an open window is information including the words "Security cannot be set because the window is open" or "The window is open. Please close it if you want to set security". According to the above configuration, there is an advantage that the user X1 can know the factor that security cannot be set.

[0038] The function control unit 211 controls the setting and cancellation of security for building Y1 according to the operation of the operation device 1 by the user X1. More specifically, the function control unit 211 of the present embodiment controls the setting and cancellation of security for building Y1 according to the operation of the operation device 1 by the user X1 based on the operation signal received from the communication unit 33 of the operation device 1.

[0039] Also, the function control unit 211 controls the setting and cancellation of security for building Y1 based on the moving direction D1 of the user X1. More specifically, the function control unit 211 controls the setting and cancellation of security for building Y1 based on the determination result of the user determination unit 22.

[0040] The notification unit 212 notifies user X1 of recommendation information for recommending security setting or cancellation based on the moving direction D1 of user X1. More specifically, the notification unit 212 transmits, based on the determination result of the user determination unit 22, the recommendation information for recommending security setting or cancellation to the user terminal X2 of user X1 via the communication unit 25, and notifies user X1 of the above recommendation information by causing the user terminal X2 to display the above recommendation information. As an example, the recommendation information for recommending security setting is information including the statement "Don't you set security?". On the other hand, the recommendation information for recommending security cancellation is information including the statement "Don't you cancel security?".

[0041] Hereinafter, specifically, the operation of the control unit 21 (function control unit 211 and notification unit 212) will be described.

[0042] When the user determination unit 22 determines that the security for building Y1 is set and user X1 has returned home to building Y1, the control unit 21 controls the cancellation of security or notifies the recommendation information for recommending the cancellation of security to user X1 among the recommendation information. More specifically, in the control unit 21, when the user determination unit 22 determines that the security for building Y1 is set and user X1 has returned home to building Y1, the function control unit 211 controls the cancellation of security, or the notification unit 212 notifies user X1 of the recommendation information for recommending the cancellation of security. According to this configuration, when the function control unit 211 controls the cancellation of security, it becomes unnecessary for user X1 to cancel the security. Also, when the notification unit 212 notifies user X1 of the recommendation information for recommending the cancellation of security, it is possible to suppress user X1 from forgetting to cancel the security. In short, when user X1 returns home to building Y1, there is an advantage that the convenience of user X1 can be improved.

[0043] On the other hand, when the security for building Y1 is not set and the user determination unit 22 determines that the user X1 goes out of building Y1, the control unit 21 controls the security setting or notifies the user X1 of the recommendation information that recommends the security setting among the recommendation information. More specifically, in the control unit 21, when the security for building Y1 is not set and the user determination unit 22 determines that the user X1 goes out of building Y1, the function control unit 211 controls the security setting, or the notification unit 212 notifies the user X1 of the recommendation information that recommends the security setting. According to this configuration, when the function control unit 211 controls the security setting, it becomes unnecessary for the user X1 to set the security. Also, when the notification unit 212 notifies the user X1 of the recommendation information that recommends the security setting, it is possible to suppress the user X1 from forgetting to set the security. In short, when the user X1 goes out of building Y1, there is an advantage that the convenience of the user X1 can be improved.

[0044] More specifically, the control unit 21 controls the security settings according to the number of people detected by the detection unit 23, or notifies the user X1 of the recommendation information that recommends the security settings among the recommendation information. More specifically, in the control unit 21, according to the determination result of the number determination unit 24, the function control unit 211 controls the security settings, or the notification unit 212 notifies the user X1 of the recommendation information that recommends the security settings. In the control unit 21 of the present embodiment, when the number determination unit 24 determines that the number of people at home is 0, the function control unit 211 controls the security settings, or the notification unit 212 notifies the user X1 of the recommendation information that recommends the security settings. On the other hand, in the control unit 21 of the present embodiment, when the number determination unit 24 determines that the number of people at home is not 0 (that is, 1 or more), the function control unit 211 does not control the security settings, and the notification unit 212 notifies the user X1 of the recommendation information that recommends the security settings. According to the above configuration, when at least one person exists inside the building Y1, it is possible to suppress the function control unit 211 from controlling the security settings. In short, there is an advantage that it is possible to suppress unnecessary control of the security settings.

[0045] (User determination unit) The user determination unit 22 determines whether the user X1 has returned home to the building Y1 or has gone out of the building Y1 based on the moving direction D1 of the user X1. As described above, the moving direction D11 (see FIG. 2) when the user X1 returns home to the building Y1 and the moving direction D12 (see FIG. 3) when the user X1 goes out of the building Y1 are different directions. Therefore, the user determination unit 22 can determine whether the user X1 has returned home to the building Y1 or has gone out of the building Y1 based on the moving direction D1 of the user X1 included in the moving direction signal received from the communication unit 25 of the control device 2.

[0046] Specifically, when the movement direction D1 of user X1 included in the movement direction signal transmitted from the communication unit 25 of the control device 2 is the movement direction D11 (see FIG. 2) when user X1 returns home to building Y1, the user determination unit 22 determines that user X1 has returned home to building Y1. On the other hand, when the movement direction D1 of user X1 included in the movement direction signal transmitted from the communication unit 25 of the control device 2 is the movement direction D12 (see FIG. 3) when user X1 goes out from building Y1, the user determination unit 22 determines that user X1 has gone out from building Y1.

[0047] (Detection unit) Unlike user X1, the detection unit 23 detects the number of people present in building Y1, which is the number of people present inside building Y1. The "person present inside building Y1" as referred to here is a person staying inside building Y1 and a person who has entered inside building Y1 and has not yet gone out from building Y1.

[0048] The detection unit 23 of the present embodiment is a module different from the positioning unit 11. The detection unit 23 of the present embodiment detects an identification signal transmitted from an external device owned by a person present inside building Y1 and detects the number of people present based on the above identification signal. More specifically, the detection unit 23 of the present embodiment detects an identification signal transmitted from an external device owned by a person present inside building Y1 and detects the number of external devices present inside building Y1 based on the above identification signal as the number of people present. According to the above configuration, there is an advantage that the number of people present can be detected more accurately. Here, the "identification information" is information that is pre-associated one-to-one with each external device. In the present disclosure, the external device is assumed to be a smartphone, a tablet-type computer, etc. owned by a person present inside building Y1. As an example, the detection unit 23 of the present embodiment is a communication module capable of wireless communication such as Bluetooth (registered trademark), Wi-Fi (registered trademark), etc.

[0049] The detection unit 23 of the present embodiment outputs the detected number of people present to the number determination unit 24.

[0050] (Number determination unit) The number determination unit 24 determines whether the number of people at home is 0 based on the number of people at home detected by the detection unit 23. In other words, the number determination unit 24 determines whether the number of people at home is 1 or more based on the number of people at home detected by the detection unit 23.

[0051] The number determination unit 24 of the present embodiment outputs the determination result to the control unit 21.

[0052] (Communication unit) The communication unit 25 is configured to be able to communicate with each of a communication unit 15 (to be described later) of the operation device 1, a locking / unlocking device 3, and a security device 4. The communication unit 25 of the present embodiment is a communication module capable of wireless communication with each of a communication unit 15 (to be described later) of the operation device 1, a locking / unlocking device 3, and a security device 4. The communication unit 25 may directly perform wireless communication with each of a communication unit 15 (to be described later) of the operation device 1, a locking / unlocking device 3, and a security device 4, or may indirectly perform wireless communication via a repeater or the like. For example, the communication unit 25 is a communication module capable of wireless communication compliant with a communication standard such as Wi-Fi (registered trademark). Note that the communication unit 25 may be a communication module capable of wired communication compliant with a communication standard such as a wired LAN.

[0053] The communication unit 25 outputs the movement direction signal received from the communication unit 15 of the operation device 1 to the user determination unit 22. Further, the communication unit 25 outputs the operation signal received from the communication unit 15 of the operation device 1 to the control unit 21.

[0054] (2-4) Locking / unlocking device The locking / unlocking device 3 is a device that locks and unlocks the door lock of the building Y1. More specifically, the locking / unlocking device 3 unlocks the door lock of the building Y1 according to the attribute of the approaching user X1. Note that the "door lock" referred to in the present disclosure is the lock of a door Y2 provided at the entrance of the building Y1, and is, for example, an electric lock.

[0055] The unlocking and locking device 3 of this embodiment receives an identification signal transmitted from the user terminal X2 owned by the user X1. Note that the unlocking and locking device 3 may receive an identification signal transmitted from a dedicated terminal (for example, a remote control key, etc.) owned by the user X1.

[0056] When the received identification signal matches the pre-registered identification signal, the unlocking and locking device 3 of this embodiment unlocks the door lock of the building Y1. On the other hand, when the received identification signal does not match the pre-registered identification signal, the unlocking and locking device 3 does not unlock the door lock of the building Y1.

[0057] (2-5) Security device The security device 4 is a device that detects the presence or absence of an abnormality in the building Y1 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 Y1 in a state where security for the building Y1 is set by the control unit 21 of the control device 2. "Abnormality" as referred to in this disclosure assumes, for example, that an unexpected person (such as a burglar) enters the building Y1 from an opening such as the door Y2 or window of the building Y1.

[0058] The security device 4 of this embodiment is a detection sensor provided at openings such as the door Y2 and windows of the building Y1, and detects that the above-mentioned opening has been opened. The detection sensor detects that an unexpected person (such as a burglar) has entered the building Y1 from the opening by detecting that the opening has been opened.

[0059] (3) Security method A security method for the security system 100 of this embodiment to monitor the presence or absence of an abnormality in the building Y1 will be described using the flowchart of FIG. 4.

[0060] As shown in FIG. 4, the security method of this embodiment includes a positioning step ST1, an estimation step ST2, a user determination step ST3, setting determination steps ST4 and ST6, a state determination step ST7, a number determination step ST8, a first control step ST5, a second control step ST9, a third control step ST10, and a factor output step ST11.

[0061] In the positioning step ST1, the positioning unit 11 measures the position of the user X1 based on a signal transmitted from the user terminal X2 owned by the user X1 who is moving inside the building Y1. In the positioning step ST1 of this embodiment, the positioning unit 11 measures the position of the user terminal X2 measured based on the identification signal transmitted from the user terminal X2 as the position of the user X1. Then, in the estimation step ST2, the estimation unit 12 estimates the moving direction D1 (see FIGS. 2 and 3) of the user X1 based on the positioning result of the positioning unit 11. More specifically, in the estimation step ST2, the estimation unit 12 estimates the moving direction D1 of the user X1 based on the difference between the position of the user X1 detected by the positioning unit 11 before a predetermined time has elapsed and the position of the user X1 detected by the positioning unit 11 after the predetermined time has elapsed.

[0062] In the user determination step ST3, the user determination unit 22 determines whether user X1 has returned home to building Y1 or has gone out from building Y1 based on the moving direction D1 of user X1. In other words, in the user determination step ST3, the user determination unit 22 determines whether user X1 has returned home to building Y1 based on the moving direction D1 of user X1. Specifically, in the user determination step ST3, when the moving direction D1 of user X1 included in the moving direction signal transmitted from the communication unit 25 of the control device 2 is the moving direction D11 (see FIG. 2) when user X1 returns home to building Y1, the user determination unit 22 determines that user X1 has returned home to building Y1 (ST3: Yes). On the other hand, in the user determination step ST3, when the moving direction D1 of user X1 included in the moving direction signal transmitted from the communication unit 25 of the control device 2 is the moving direction D12 (see FIG. 3) when user X1 goes out from building Y1, the user determination unit 22 determines that user X1 has gone out from building Y1 (ST3: No).

[0063] When the user determination unit 22 determines that user X1 has returned home to building Y1 (ST3: Yes), the function control unit 211 performs a setting determination step ST4 to determine whether security for building Y1 is set. When the function control unit 211 determines that security for building Y1 is set (ST4: Yes), the control unit 21 performs a first control step ST5 to control the release of security or notify user X1 of recommendation information for recommending the release of security. More specifically, in the first control step ST5, the function control unit 211 controls the release of security, or the notification unit 212 notifies user X1 of recommendation information for recommending the release of security. On the other hand, when the function control unit 211 determines that security for building Y1 is not set (ST4: No), the control unit 21 does not control the release of security and does not recommend the release of security to user X1. That is, when the control unit 21 determines that security for building Y1 is not set (ST4: No), the control unit 21 does not perform an operation.

[0064] When the user determination unit 22 determines that the user X1 goes out of the building Y1 (ST3: No), the control unit 21 performs a setting determination step ST6 of determining whether security for the building Y1 is set. When the function control unit 211 determines that security for the building Y1 is set (ST6: Yes), the control unit 21 does not control the security setting and does not recommend the security setting to the user X1. That is, when the function control unit 211 determines that security for the building Y1 is set (ST6: Yes), the control unit 21 does not perform an operation.

[0065] On the other hand, when the function control unit 211 determines that security for the building Y1 is not set (ST6: No), the function control unit 211 performs a state determination step ST7 of determining whether the security can be set. When the function control unit 211 determines that the security cannot be set (ST7: NO), the output unit 213 outputs factor information including the factor that the security cannot be set to the user terminal X2. On the other hand, when the function control unit 211 determines that the security can be set (ST7: Yes), the number determination unit 24 performs a number determination step ST8 of determining whether the number of people at home is 0 based on the number of people at home detected by the detection unit 23. In other words, in the number determination step ST8, the number determination unit 24 determines whether the number of people at home is 1 or more based on the number of people at home detected by the detection unit 23.

[0066] When the number determination unit 24 determines that the number of people at home is 0 (Number determination step ST8: Yes), the control unit 21 performs a second control step ST9 of controlling the security settings or notifying the user X1 of recommendation information for recommending the security settings. More specifically, in the second control step ST9, the function control unit 211 controls the security settings, or the notification unit 212 notifies the user X1 of recommendation information for recommending the security settings. On the other hand, when the number determination unit 24 determines that the number of people at home is not 0 (i.e., one or more) (Number determination step ST8: No), the control unit 21 performs a third control step ST10 of not controlling the security settings and notifying the user X1 of recommendation information for recommending the security settings. More specifically, in the third control step ST10, the function control unit 211 does not control the security settings, and the notification unit 212 notifies the user X1 of recommendation information for recommending the security settings.

[0067] From the above, in each of the first control step ST5, the second control step ST9, and the third control step ST10, the control unit 21 controls the setting or cancellation of security based on the movement direction D1 of the user X1 estimated in the estimation step ST2, or notifies the user X1 of recommendation information for recommending the setting or cancellation of security. That is, each of the first control step ST5, the second control step ST9, and the third control step ST10 corresponds to the control step of the present disclosure.

[0068] (4) Variation The above-described embodiment is only one of various embodiments of the present disclosure. The above-described embodiment can be variously modified according to the design and the like as long as the object of the present disclosure can be achieved. The following variations may be realized in appropriate combinations. Also, functions similar to those of the security system 100 according to the above-described embodiment may be embodied by a program that is a computer program or a non-transitory recording medium on which the program is recorded. A program according to one aspect is a program for causing a computer system to execute the security method in the above-described embodiment.

[0069] In the above-described embodiment, the detection unit 23 detects an identification signal transmitted from an external device owned by a person present inside the building Y1, and detects the number of people at home based on the identification signal. However, the detection unit 23 may acquire the power consumption consumed inside the building Y1, and detect the number of people at home based on the power consumption. In this case, the number determination unit 24 determines that the number of people at home is 0 when the power consumption consumed inside the building Y1 is equal to or less than a predetermined value, and determines that the number of people at home is 1 or more when the power consumption is greater than the predetermined value. According to the above configuration, there is an advantage that even when a person present inside the building Y1 does not own an external device, the number of people at home can be detected more accurately. In short, there is an advantage that the number of people at home can be detected more accurately regardless of the person present inside the building Y1.

[0070] Also, in the above-described embodiment, the detection unit 23 is a module different from the positioning unit 11. However, the detection unit 23 may include the positioning unit 11. In this case, the detection unit 23 may estimate the moving direction of a person based on the result of measuring the position of a person entering or leaving the building Y1, and calculate the number of people at home from the moving direction of the person. More specifically, the detection unit 23 may count the number of people entering the building Y1 and the number of people leaving the building Y1 based on the estimated moving direction of the person, and calculate the number of people at home by subtracting the number of people leaving the building Y1 from the number of people entering the building Y1. According to the above configuration, there is an advantage that the configuration of the security system 100 can be simplified.

[0071] In the above-described embodiment, the operation device 1 includes both the positioning unit 11 and the estimation unit 12, but the control device 2 may include at least one of the positioning unit 11 and the estimation unit 12.

[0072] In the above-described embodiment, the locking and unlocking device 3 is a device for locking and unlocking a door lock that is an electric lock. However, the locking and unlocking device 3 may be a device for locking and unlocking a door lock such as a cylinder lock. The locking and unlocking device 3 may be a mechanical structure in which a key corresponding to the above-described cylinder lock is inserted and the door lock is locked and unlocked by rotating the key.
