[0010] In the following embodiments, the security system 3, security method, and program of the present disclosure will be described with reference to the accompanying drawings. However, the following embodiments are merely a part of the various embodiments of the present disclosure. The following embodiments can be modified in various ways depending on the design, etc., as long as the object of the present disclosure can be achieved. Furthermore, the following embodiments, including modified examples, may be realized in appropriate combinations.

[0011] (Embodiment 1) (overview) The security system 3 performs security management in a management area A3 (see FIG. 2) of a facility such as a house. FIG. 2 shows the management area A3 when the facility is a detached house, and the management area A3 is, for example, a space within a building Y1. Note that the management area A3 is not limited to a space within the building Y1, and may be, for example, a space within a site that includes the building Y1.

[0012] Furthermore, if the facility is an apartment building, the management area A3 is, for example, a dwelling unit (private area) of the apartment building.

[0013] The facilities that are the targets of security management by the security system 3 are not limited to homes, but may also be, for example, offices, factories, hotels, nursing homes, or hospitals. The following describes an example in which the security system 3 manages the security of a detached house.

[0014] As part of security management, the security system 3 sets and releases security for the managed area A3. In this disclosure, "setting security" means setting the managed area A3 to monitor for abnormalities, and "releasing security" means setting the managed area A3 not to monitor for abnormalities.

[0015] More specifically, when security is enabled, the home security controller (hereinafter referred to as the controller 4) monitors whether or not there is an abnormality in the managed area A3. By issuing a command to the controller 4, the security system 3 switches between a state in which the controller 4 monitors whether or not there is an abnormality in the managed area A3 (a state in which security is enabled) and a state in which the controller 4 does not monitor whether or not there is an abnormality in the managed area A3 (a state in which security is disabled).

[0016] An abnormality in the managed area A3 is, for example, a situation in which a person (e.g., a burglar) has illegally entered the managed area A3. The controller 4 determines the open / close state of the front door Y2 and windows of the building Y1, for example, based on the output of sensors installed on the front door Y2 and windows. When the front door Y2 or windows are opened while security is enabled, the controller 4 determines that an abnormality has occurred in the managed area A3. When the controller 4 determines that an abnormality has occurred in the managed area A3, it performs actions such as issuing an alarm (which may include voice) or reporting the occurrence to a predetermined contact point (such as a security company).

[0017] For example, in a situation where security is set, user U1 (resident) temporarily disables security when passing through front door Y2. User U1 sets security when going out, for example. User U1 also disables security as appropriate while at home. For example, user U1 sets security when only children are home alone in building Y1, and disables security when adults are at home.

[0018] (Main components and processing) Next, the main components and processing of the security system 3 will be described with reference to FIGS. 1 and 2. The security system 3 includes a first acquisition unit 311, a second acquisition unit 312, a determination unit 313, and a control unit 314. The first acquisition unit 311 acquires location information of user U1 measured by the measurement device X2 based on a signal transmitted from a user terminal X1 owned by user U1. The second acquisition unit 312 acquires user information for distinguishing user U1. The determination unit 313 determines, based on the location information, a situation in which user U1 leaves the managed area A3 and a situation in which user U1 enters the managed area A3. When the situation determined by the determination unit 313 is at least one of a situation in which user U1 leaves the managed area A3 and a situation in which user U1 enters the managed area A3, the control unit 314 performs a first process of controlling the activation or deactivation of security for the managed area A3, or a second process of notifying user U1 of recommendation information recommending the activation or deactivation of security. The control unit 314 determines whether to perform the first process or the second process according to the user information.

[0019] According to the above configuration, the control unit 314 can perform the first process when a certain user U1 enters or leaves the managed area A3, and can perform the second process when another certain user U1 enters or leaves the managed area A3. Compared to a case where the control unit 314 performs the first process or the second process independently of the user U1, a more convenient security system 3 can be provided.

[0020] The measurement device X2 identifies multiple users U1 and locates each of the multiple users U1. When multiple users U1 leave the management area A3 within a certain time period, and when multiple users U1 enter the management area A3 within a certain time period, the control unit 314 determines whether to perform the first process or the second process, depending on the user information of at least one user U1 among the multiple users U1.

[0021] In addition, after the determination unit 313 determines the situation in which user U1 enters the management area A3 or the situation in which user U1 leaves the management area A3, the control unit 314 may perform the first process or the second process after a waiting time has elapsed.

[0022] Functions similar to those of the security system 3 can be embodied in a security method. The security method of this embodiment performs security management in a managed area A3. The security method includes a first acquisition step, a second acquisition step, a determination step, and a control step. The first acquisition step acquires location information of user U1 measured by a measurement device X2 based on a signal transmitted from a user terminal X1 owned by user U1. The second acquisition step acquires user information for distinguishing user U1. The determination step determines, based on the location information, a situation in which user U1 leaves the managed area A3 and a situation in which user U1 enters the managed area A3. The control step performs a first process of controlling the setting or cancellation of security for the managed area A3, or a second process of notifying user U1 of recommendation information recommending the setting or cancellation of security, when the situation determined in the determination step is at least one of a situation in which user U1 leaves the managed area A3 and a situation in which user U1 enters the managed area A3. The control step determines whether to perform the first process or the second process according to the user information.

[0023] The security method can be embodied in a program. The program of this embodiment is a program readable by a computer system and causes one or more processors of the computer system to execute the security method. The program may be recorded on a non-transitory recording medium readable by the computer system.

[0024] (detail) (1) Overall structure The security system 3 and the components associated with the security system 3 will be described in more detail below.

[0025] The security system 3 is capable of communicating with the user terminal X1, the measurement device X2, and the controller 4. In this disclosure, "capable of communication" means that signals can be exchanged directly or indirectly via a network, a repeater, or the like, using an appropriate communication method such as wired communication or wireless communication.

[0026] Each of the security system 3, user terminal X1, measurement device X2, and controller 4 includes a computer system having one or more processors and memory. At least some of the functions of each of the security system 3, user terminal X1, measurement device X2, and controller 4 are realized by the processor of the computer system executing a program recorded in the memory of the computer system. The program may be recorded in memory, provided via a telecommunications line such as the Internet, or provided by being recorded on a non-transitory recording medium (such as a memory card) readable by the computer system.

[0027] The measuring device X2 is a device that measures the position of the user U1 using ultra-wide band (UWB). The positioning error (resolution) of the measuring device X2 is, for example, about 10 cm to 1 m. It is preferable that the positioning error of the measuring device X2 is 1 m or less.

[0028] (2) User terminal The user terminal X1 is a terminal carried by the user U1. The user terminal X1 is, for example, a mobile phone such as a smartphone, a tablet computer, or a wearable terminal.

[0029] The user terminal X1 includes a processing unit 11, a communication unit 12, a storage unit 13, a transmission unit 14, an input IF (interface) unit 15, and an output IF (interface) unit 16.

[0030] The processing unit 11 includes one or more processors. The processing unit 11 executes a program to realize a predetermined function.

[0031] The communication unit 12 includes a communication interface device. The user terminal X1 is capable of communicating with the measurement device X2 and the security system 3 via the communication unit 12.

[0032] The storage unit 13 is a storage device configured by a hard disk drive (HDD), a solid state drive (SSD), etc. The storage unit 13 has an area for storing information necessary for processing by the processing unit 11.

[0033] The transmitter 14 emits a signal used for positioning by the measurement device X2. More specifically, the transmitter 14 emits a UWB signal including identification information of the user terminal X1.

[0034] The input IF unit 15 accepts an operation from the user U1. The processing unit 11 performs processing in accordance with the operation on the input IF unit 15. The input IF unit 15 has, for example, at least one of a button, a touch panel, and a touch panel display.

[0035] The output IF unit 16 notifies the user U1 of information. The output IF unit 16 includes, for example, at least one of a display for visually notifying the user U1 of information and an audio device such as a speaker for audibly notifying the user U1 of information (which may include voice).

[0036] (3) Measuring equipment The measurement device X2 is installed in the management area A3 (building Y1). The measurement device X2 is installed, for example, at the entrance (front door) of the management area A3. The measurement device X2 measures the position of the user U1 in the measurement area A2 based on a signal transmitted from the user terminal X1 and received by the measurement device X2. The measurement area A2 is an area corresponding to the entrance of the management area A3. In FIG. 2, the measurement area A2 is included in the management area A3, but at least a part of the measurement area A2 may be outside the management area A3.

[0037] The measurement device X2 includes a processing unit 21, a communication unit 22, a storage unit 23, a receiving unit 24, an input IF unit 25, and an output IF unit 26.

[0038] The processing unit 21 includes one or more processors. The processing unit 21 executes programs to realize predetermined functions. The processing unit 21 has a positioning unit 211 and a control unit 212. The positioning unit 211 performs processing to position the user U1 using UWB signals. The control unit 212 sets and releases security.

[0039] It should be noted that the positioning unit 211 and the control unit 212 merely indicate functions realized by the processing unit 21, and do not necessarily indicate actual configurations.

[0040] The communication unit 22 includes a communication interface device. The measurement device X2 is capable of communicating with the user terminal X1 and the security system 3 via the communication unit 22.

[0041] The storage unit 23 is a storage device configured by a hard disk drive (HDD), a solid state drive (SSD), etc. The storage unit 23 has an area for storing information necessary for processing by the processing unit 21.

[0042] The receiver 24 receives the UWB signal transmitted from the user terminal X1. The positioning unit 211 locates the position of the user U1 based on the UWB signal received by the receiver 24.

[0043] The input IF unit 25 accepts an operation from the user U1. The processing unit 21 performs processing in accordance with the operation on the input IF unit 25. The input IF unit 25 has, for example, at least one of a button, a touch panel, and a touch panel display.

[0044] The output IF unit 26 notifies the user U1 of information. The output IF unit 26 includes, for example, at least one of a display for visually notifying the user U1 of information and an audio device such as a speaker for audibly notifying the user U1 of information (which may include voice).

[0045] Next, the positioning unit 211 will be described in detail.

[0046] The UWB signal transmitted from the user terminal X1 includes identification information of the user terminal X1. The storage unit 23 of the measuring device X2 stores the identification information of the user terminal X1 carried by the user U1 in advance. The positioning unit 211 identifies the user terminal X1 based on the identification information included in the UWB signal. Furthermore, the positioning unit 211 determines the position of the user terminal X1 based on the UWB signal, and treats the position of the user terminal X1 as the position of the user U1.

[0047] As an example, the receiving unit 24 has multiple receivers that receive UWB signals transmitted from the user terminal X1. The positioning unit 211 measures the position of the user terminal X1 by calculating the angle at which the UWB signal arrives at the receiving unit 24 from the user terminal X1 based on the phase difference of the UWB signals at the multiple receivers. The positioning unit 211 may also measure the position of the user terminal X1 based on the difference in arrival time of the UWB signal at the multiple receivers. The positioning unit 211 may also measure the position of the user terminal X1 based on the signal strength of the UWB signal at the multiple receivers. In other words, the method by which the positioning unit 211 measures the position of the user terminal X1 is not limited.

[0048] The positioning unit 211 measures the position of the user U1 (user terminal X1) multiple times at intervals. The positioning unit 211 detects the moving direction of the user U1 in the measurement area A2 based on changes in the position of the user U1.

[0049] The following description will be given assuming that user U1 is leaving managed area A3 (building Y1) (see FIG. 2). The positioning unit 211 determines the movement direction D1 of user U1 based on the difference between the position of user U1 at a first time point and the position of user U1 at a second time point after a predetermined time has elapsed since the first time point. When user U1 leaves managed area A3, user U1 approaches front door Y2 at the second time point compared to the first time point. Therefore, the positioning unit 211 determines that the movement direction D1 of user U1 is the direction of leaving managed area A3.

[0050] Next, a case will be described in which user U1 enters management area A3 (building Y1). In this case, compared to the first time point, at the second time point, user U1 moves away from the front door Y2 and heads toward a living room (such as a living room). Therefore, the positioning unit 211 determines that the movement direction D1 of user U1 is a direction toward entering management area A3.

[0051] The positioning unit 211 determines the horizontal movement direction D1 of the user U1. The movement direction D1 when the user U1 leaves the management area A3 is opposite to the movement direction D1 when the user U1 enters the management area A3.

[0052] (4) Security system The security system 3 is, for example, a computer server. The security system 3 may be installed outside the management area A3, or may be installed inside the management area A3.

[0053] The security system 3 includes a processing unit 31 , a communication unit 32 , and a storage unit 33 .

[0054] The communication unit 32 includes a communication interface device. The security system 3 is capable of communicating with the user terminal X1, the measurement device X2, and the controller 4 via the communication unit 32.

[0055] The storage unit 33 is a storage device configured by a hard disk drive (HDD), a solid state drive (SSD), etc. The storage unit 33 has an area for storing information necessary for processing by the processing unit 31.

[0056] The processing unit 31 includes one or more processors. The processing unit 31 executes a program to realize a predetermined function. The processing unit 31 has the first acquisition unit 311, the second acquisition unit 312, the determination unit 313, and the control unit 314.

[0057] It should be noted that the first acquisition unit 311, the second acquisition unit 312, the determination unit 313, and the control unit 314 merely indicate functions realized by the processing unit 31, and do not necessarily indicate actual configurations.

[0058] The first acquisition unit 311 acquires the position information of the user U1 measured by the measurement device X2. More specifically, the first acquisition unit 311 acquires the position information of the user U1 via the communication unit 32.

[0059] The UWB signal received by the measuring device X2 includes identification information of the user terminal X1. When acquiring the location information of the user U1, the first acquiring unit 311 also acquires the identification information of the user terminal X1.

[0060] The second acquisition unit 312 acquires user information for distinguishing the user U1. The user information includes attribute information that indicates the attributes of the user U1. The attribute information includes, for example, information indicating whether the user U1 is a child or an adult.

[0061] The storage unit 33 of the security system 3 stores in advance the user information of the user U1 who owns the user terminal X1 in association with the identification information of the user terminal X1. When the first acquisition unit 311 acquires the identification information of the user terminal X1, the second acquisition unit 312 acquires (reads) the user information associated with the identification information of the user terminal X1 from the storage unit 33.

[0062] The user information for each user U1 is input, for example, by operating the input IF unit 15 or 25, and is stored in the storage unit 33 of the security system 3. In other words, the user information can be arbitrarily set by the user U1 or the like.

[0063] The determination unit 313 determines, based on the position information of user U1, the situation in which user U1 leaves the management area A3 and the situation in which user U1 enters the management area A3. If the movement direction D1 of user U1 determined by the positioning unit 211 is the direction of leaving the management area A3, the determination unit 313 determines that user U1 is in the situation of leaving the management area A3. If the movement direction D1 of user U1 determined by the positioning unit 211 is the direction of entering the management area A3, the determination unit 313 determines that user U1 is in the situation of entering the management area A3.

[0064] The control unit 314 performs the first process or the second process described above.

[0065] The first process is a process for controlling the setting or release of security for the management area A3. More specifically, the first process is a process for instructing the controller 4 to set or release security.

[0066] When the determination unit 313 determines that the user U1 is about to leave the management area A3, the first process is to set up security. When the determination unit 313 determines that the user U1 is about to enter the management area A3, the first process is to release security.

[0067] The second process is a process of notifying user U1 of recommendation information that recommends setting or canceling security. If the determination unit 313 determines that user U1 is in a situation to leave the management area A3, the second process is a process of notifying user U1 of recommendation information that recommends setting security. If the determination unit 313 determines that user U1 is in a situation to enter the management area A3, the second process is a process of notifying user U1 of recommendation information that recommends canceling security.

[0068] In the second process, the control unit 314 transmits the recommended information to the user terminal X1. In the second process, the control unit 314 transmits the recommended information to the user terminal X1 via the communication unit 32. When the user terminal X1 receives the recommended information, the output IF unit 16 notifies the user U1 of the recommended information. The output IF unit 16 notifies the user U1 of the recommended information, for example, by displaying the recommended information on the display of the output IF unit 16. Upon receiving the recommended information, the user U1 can set or release security by operating the input IF unit 15 of the user terminal X1. The control unit 314 of the security system 3 outputs a command to the controller 4 to set or release security in accordance with the operation on the input IF unit 15 of the user terminal X1.

[0069] User U1 can also set or release security by operating input IF unit 25 of measurement device X2. Control unit 212 of measurement device X2 outputs a command to controller 4 to set or release security in response to an operation on input IF unit 25.

[0070] When user U1 voluntarily sets or cancels security, user U1 operates user terminal X1, for example, to start a security management application and perform an operation to set or cancel security. For example, in response to the operation of user U1, an operation screen that accepts operations to set or cancel security is displayed on the display of output IF unit 16 of user terminal X1, and user U1 sets or cancels security by operating the operation screen.

[0071] On the other hand, in the second process, a security management application is automatically started, and an operation screen for accepting operations for setting or canceling security is displayed on the display of the output IF unit 16 of the user terminal X1. Thereafter, the user U1 operates the operation screen to set or cancel security.

[0072] As described above, the control unit 314 performs the first process or the second process when the situation determined by the determination unit 313 is at least one of a situation where the user U1 is leaving the management area A3 and a situation where the user U1 is entering the management area A3. In the following, it is assumed that the control unit 314 performs the first process or the second process when the situation determined by the determination unit 313 is a situation where the user U1 is leaving the management area A3.

[0073] When the situation determined by the determination unit 313 is that the user U1 is leaving the management area A3, the control unit 314 determines whether to perform the first process or the second process according to the user information. More specifically, the control unit 314 determines whether to perform the first process or the second process according to the attribute information included in the user information.

[0074] The attribute information is classified into first attribute information and second attribute information. In this embodiment, the attribute information indicating that the user U1 is a child corresponds to the first attribute information. Also, the attribute information indicating that the user U1 is an adult corresponds to the second attribute information.

[0075] When the attribute information corresponding to user U1 leaving management area A3 is first attribute information, control unit 314 performs first processing, and when the attribute information corresponding to user U1 leaving management area A3 is second attribute information, control unit 314 performs second processing.

[0076] Furthermore, if the situation determined by the determination unit 313 is that the user U1 is entering the management area A3, the control unit 314 may, for example, perform a predetermined process out of the first process or the second process, or may not perform either the first process or the second process.

[0077] (5) Controller The controller 4 switches between a state in which security is set and a state in which security is released based on a command from the control unit 314 of the security system 3 or a command from the control unit 212 of the measurement device X2.

[0078] As described above, in a state where security is set, when the front door Y2 or a window is opened, the controller 4 determines that an abnormality has occurred in the managed area A3 and issues a report or the like.

[0079] Furthermore, the controller 4 may control predetermined devices installed in the managed area A3 depending on whether the security is enabled or disabled. For example, when the security is disabled, the controller 4 may turn on the lighting fixtures 51 or start the operation of the air conditioner 52. For example, when the security is enabled, the controller 4 may lock the electric lock on the front door Y2.

[0080] (6) Operation flow The operational flow of the security system 3 will be described with reference to Figures 3 and 4. However, Figures 3 and 4 merely show one example of a method of using the security system 3 (security method) according to the present disclosure, and the order of processing may be changed as appropriate, and processing may be added or omitted as appropriate.

[0081] The measurement device X2 intermittently measures the position of the user U1 and generates position information of the user U1. The first acquisition unit 311 of the security system 3 intermittently acquires the position information from the measurement device X2 (step ST1). The first acquisition unit 311 also acquires identification information of the user terminal X1 along with the position information, and the second acquisition unit 312 acquires user information associated with the identification information from the storage unit 33 (step ST2).

[0082] The determination unit 313 determines the situation in which the user U1 leaves the management area A3 and the situation in which the user U1 enters the management area A3 based on the position information acquired by the first acquisition unit 311 (step ST3). If the situation is such that the user U1 leaves the management area A3 (step ST4: Yes), the control unit 314 performs the first process or the second process (step ST5).

[0083] 4 shows a process in which the control unit 314 determines whether to perform the first process or the second process when the user U1 leaves the management area A3. The control unit 314 refers to the attribute information included in the user information acquired in step ST2.

[0084] If the attribute information is the first attribute information, that is, if the user U1 is a child, the control unit 314 performs a first process (step ST11: Yes, step ST12). In the first process, the control unit 314 sets security.

[0085] If the attribute information is the second attribute information, that is, if the user U1 is an adult, the control unit 314 performs a second process (step ST11: No, step ST13). In the second process, the control unit 314 notifies the user U1 of recommendation information that recommends security settings.

[0086] Furthermore, if the situation determined by the determination unit 313 in step ST3 is that the user U1 is entering the management area A3, the control unit 314 may, for example, perform a predetermined process out of the first process or the second process, or may not perform either the first process or the second process.

[0087] (First Modification of the First Embodiment) The following describes a first modified example of the first embodiment. The same components as those in the first embodiment are denoted by the same reference numerals and will not be described again. The first modified example may be applied to the second and third embodiments described below.

[0088] When multiple users U1 leave the management area A3 within a certain period of time, the control unit 314 determines whether to perform the first process or the second process based on the user information of at least one user U1 among the multiple users U1.

[0089] For example, if multiple users U1 leave the management area A3 within a certain period of time, the control unit 314 identifies the user U1 who is farthest from the entrance / exit of the management area A3 (for example, the position of the front door Y2) based on the positioning result of the measurement device X2. The control unit 314 determines whether to perform the first process or the second process based on the user information of the user U1 who is farthest from the entrance / exit of the management area A3 among the multiple users U1. In other words, the control unit 314 determines whether to perform the first process or the second process based on the user information of the user U1 who is determined to be last to leave the management area A3.

[0090] For example, if the user information of the user U1 who is farthest from the entrance / exit of the management area A3 includes the second attribute information, that is, if the user U1 is an adult, the control unit 314 performs the second process.

[0091] (Second Modification of the First Embodiment) The following describes a second modified example of embodiment 1. The same components as those in embodiment 1 are denoted by the same reference numerals and descriptions thereof will be omitted. The second modified example may be applied to embodiments 2 and 3 described below.

[0092] A priority is set for each of the multiple users U1. The priority is stored, for example, in the storage unit 33 of the security system 3. For example, the priority input by operating the input IF unit 15 or 25 is stored in the storage unit 33.

[0093] When multiple users U1 leave the management area A3 within a certain time period, the control unit 314 determines whether to perform the first process or the second process based on the user information of the user U1 with the highest priority among the multiple users U1. For example, when the user information of the user U1 with the highest priority includes the second attribute information, that is, when the user U1 is an adult, the control unit 314 performs the second process.

[0094] Note that the priority may be set automatically according to the attribute information of the user U1. For example, the priority of the user U1 whose attribute information is the second attribute information may be set higher than the priority of the user U1 whose attribute information is the first attribute information.

[0095] (Embodiment 2) The following describes a security system 3 according to embodiment 2. The same components as those in embodiment 1 are given the same reference numerals and descriptions thereof will be omitted.

[0096] The control unit 314 of this embodiment determines whether to perform the first process or the second process, based on the user information and the number of people present in the management area A3.

[0097] FIG. 5 shows the process in which the control unit 314 determines whether to perform the first process or the second process when the user U1 leaves the management area A3.

[0098] If the attribute information corresponding to the user U1 who leaves the management area A3 is the first attribute information, that is, if the user U1 is a child, the control unit 314 performs a first process (step ST21: Yes, step ST22). In the first process, the control unit 314 sets up security.

[0099] If the attribute information corresponding to user U1 leaving management area A3 is second attribute information, that is, if user U1 is an adult, the first process or second process is selected depending on whether there is anyone remaining in management area A3 when user U1 leaves management area A3. In other words, the first process or second process is selected depending on whether there is anyone other than user U1 in management area A3.

[0100] If there is anyone remaining in the management area A3, the control unit 314 performs a second process (step ST23: Yes, step ST24). In the second process, the control unit 314 notifies the user U1 of recommendation information that recommends security settings.

[0101] If no one remains in the management area A3, the control unit 314 performs a first process (step ST23: No, step ST22). In the first process, the control unit 314 sets up security.

[0102] As a modified example, the control unit 314 may perform the second process when the attribute information corresponding to the user U1 leaving the management area A3 is the second attribute information and a person associated with the first attribute information remains in the management area A3. The control unit 314 may perform the first process when the attribute information corresponding to the user U1 leaving the management area A3 is the second attribute information and a person associated with the first attribute information does not remain in the management area A3.

[0103] (Embodiment 3) The following describes a security system 3 according to embodiment 3. The same components as those in embodiment 1 are given the same reference numerals and descriptions thereof will be omitted.

[0104] The control unit 314 of this embodiment determines whether to perform the first process or the second process, based on the user information and the number of people present in the management area A3.

[0105] FIG. 6 shows the process in which the control unit 314 determines whether to perform the first process or the second process when the user U1 leaves the management area A3.

[0106] If the attribute information corresponding to user U1 leaving management area A3 is first attribute information (step ST31: Yes), that is, if user U1 is a child, the first process or the second process is selected depending on whether there is anyone remaining in management area A3 when user U1 leaves management area A3. In other words, the first process or the second process is selected depending on whether there is anyone other than user U1 in management area A3.

[0107] If there is anyone remaining in the management area A3, the control unit 314 performs a second process (step ST32: Yes, step ST34). In the second process, the control unit 314 notifies the user U1 of recommendation information that recommends security settings.

[0108] If no one remains in the management area A3, the control unit 314 performs a first process (step ST32: No, step ST33). In the first process, the control unit 314 sets up security.

[0109] If the attribute information corresponding to user U1 leaving management area A3 is the second attribute information, that is, if user U1 is an adult, control unit 314 performs second processing (step ST31: No, step ST34). In the second processing, control unit 314 notifies user U1 of recommendation information that recommends security settings.

[0110] As a modified example, the control unit 314 may perform the second process when the attribute information corresponding to the user U1 leaving the management area A3 is the first attribute information and a person associated with the first attribute information remains in the management area A3. The control unit 314 may perform the first process when the attribute information corresponding to the user U1 leaving the management area A3 is the first attribute information and no person associated with the first attribute information remains in the management area A3.

[0111] (Other Modifications of Embodiments 1 to 3) Other variations of the first to third embodiments are listed below. The following variations may be implemented in appropriate combinations. The following variations may also be implemented in appropriate combinations with the above-described variations. Hereinafter, the configurations of the first to third embodiments described above will be referred to as basic examples 1 to 3.

[0112] In Basic Examples 1 to 3, the measuring device X2 is a device that measures the position of the user U1 using UWB. However, the positioning method of the measuring device X2 is not limited. For example, the measuring device X2 may be a device that measures the position of the user U1 using Bluetooth (registered trademark). Also, the measuring device X2 may be a device that measures the position of the user U1 using WiFi (registered trademark).

[0113] The measuring device X2 may be a component of a security system 3.

[0114] The controller 4 may be a component of the security system 3 .

[0115] In basic examples 1 to 3, the attribute information indicating that user U1 is a child corresponds to the first attribute information. At least one of the attribute information indicating that user U1 is a child and the attribute information indicating that user U1 is an elderly person may also correspond to the first attribute information.

[0116] The user information does not have to include attribute information.

[0117] The user information may include identification information of user U1. The identification information of user U1 may be stored in the storage unit 33 in association with information (hereinafter referred to as first designation information) that specifies whether the control unit 314 should perform the first process or the second process when user U1 leaves the management area A3. When user U1 leaves the management area A3, the control unit 314 reads the first designation information associated with the user's identification information from the storage unit 33 and performs the process specified by the first designation information, either the first process or the second process. In this way, whether the control unit 314 should perform the first process or the second process when user U1 leaves the management area A3 may be set for each user U1.

[0118] The identification information of user U1 may be associated with information (hereinafter referred to as second designation information) that specifies whether the control unit 314 should perform the first process or the second process when user U1 enters the management area A3, and stored in the storage unit 33. When user U1 enters the management area A3, the control unit 314 reads the second designation information associated with the identification information of user U1 from the storage unit 33, and performs the process specified by the second designation information, either the first process or the second process. In this way, whether the control unit 314 should perform the first process or the second process when user U1 enters the management area A3 may be set for each user U1.

[0119] When a first user leaves management area A3, control unit 314 may determine whether to perform the first process or the second process based on the user information of a second user remaining in management area A3. For example, when the user information of the second user includes second attribute information, control unit 314 may perform the second process.

[0120] When performing the second process, the control unit 314 may notify the second user remaining in the management area A3 of the recommended information.

[0121] When user U1 enters management area A3, control unit 314 may determine whether to perform the first process or the second process according to the user information. For example, when attribute information corresponding to user U1 entering management area A3 is first attribute information, control unit 314 may perform the first process, and when attribute information corresponding to user U1 entering management area A3 is second attribute information, control unit 314 may perform the second process.

[0122] The security system 3 or security method according to the present disclosure includes a computer system. The computer system primarily comprises a processor and memory as hardware. At least a portion of the functions of the security system 3 or security method according to the present disclosure are realized by the processor executing a program stored in the computer system's memory. The program may be pre-stored in the computer system's memory, provided via a telecommunications line, or provided on a non-transitory recording medium such as a memory card, optical disk, or hard disk drive that is readable by the computer system. The processor of the computer system is composed of one or more electronic circuits, including a semiconductor integrated circuit (IC) or a large-scale integrated circuit (LSI). The term "integrated circuit" as used here refers to an integrated circuit such as an IC or LSI, and includes integrated circuits called system LSIs, very large-scale integration (VLSI), or ultra-large-scale integration (ULSI). Furthermore, a field-programmable gate array (FPGA), which is programmable after the LSI is manufactured, or a logic device capable of reconfiguring the connections within the LSI or the circuit partitions within the LSI, can also be used as a processor. The electronic circuits may be integrated into one chip or distributed across multiple chips. The chips may be integrated into one device or distributed across multiple devices. The computer system referred to here includes a microcontroller having one or more processors and one or more memories. Therefore, the microcontroller is also composed of one or more electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

[0123] Furthermore, in Basic Examples 1 to 3, multiple functions that are integrated into one device may be distributed across multiple devices. For example, the device that constitutes the determination unit 313 may be provided separately from the device that constitutes the control unit 314. At least some of the functions of the security system 3, for example, the function of the determination unit 313, may be realized by the cloud (cloud computing) or the like.

[0124] Conversely, the functions distributed among multiple devices in Basic Examples 1 to 3 may be integrated into one device. For example, at least some of the functions of positioning unit 211 may be provided in security system 3.

[0125] (Reference example) A security system and a security method according to a reference example will be described below.

[0126] The configuration of the security system of the reference example is the same as that of the first to third embodiments.

[0127] In the reference example, when one or more users U1 leave the management area A3, the control unit 314 determines whether to perform the first process or the second process based on the number of people present in the management area A3, instead of based on the user information. The other processes are the same as those in the first to third embodiments.

[0128] For example, if one or more users U1 leave the management area A3, and the management area A3 is left empty, the control unit 314 performs a first process. In the first process, the control unit 314 sets security.

[0129] Furthermore, if one or more users U1 leave the management area A3 but someone remains in the management area A3, the control unit 314 performs a second process. In the second process, the control unit 314 notifies the user U1 of recommendation information that recommends security settings.

[0130] (summary) The above-described embodiments and the like disclose the following aspects.

[0131] A security system (3) according to a first aspect performs security management in a managed area (A3). The security system (3) includes a first acquisition unit (311), a second acquisition unit (312), a determination unit (313), and a control unit (314). The first acquisition unit (311) acquires location information of a user (U1) measured by a measurement device (X2) based on a signal transmitted from a user terminal (X1) owned by the user (U1). The second acquisition unit (312) acquires user information for distinguishing the user (U1). The determination unit (313) determines, based on the location information, the circumstances under which the user (U1) leaves the managed area (A3) and the circumstances under which the user (U1) enters the managed area (A3). When the situation determined by the determination unit 313 is at least one of a situation in which the user (U1) is leaving the management area (A3) and a situation in which the user (U1) is entering the management area (A3), the control unit 314 performs a first process of controlling the setting or release of security for the management area (A3) or a second process of notifying the user (U1) of recommendation information recommending the setting or release of security. The control unit 314 determines whether to perform the first process or the second process according to the user information.

[0132] According to the above configuration, the control unit 314 can perform the first process when a certain user U1 enters or leaves the managed area A3, and can perform the second process when another certain user U1 enters or leaves the managed area A3. This makes it possible to provide a more convenient security system 3 compared to a case where the control unit 314 performs the first process or the second process independently of the user U1.

[0133] In the security system (3) according to the second aspect, the user information in the first aspect includes attribute information representing attributes of the user (U1). The control unit (314) determines whether to perform the first process or the second process according to the attribute information.

[0134] According to the above configuration, user information can be easily set.

[0135] In the security system (3) according to the third aspect, in the second aspect, when the attribute information corresponding to the user (U1) leaving the management area (A3) is the first attribute information, the control unit (314) performs the first process. When the attribute information corresponding to the user (U1) leaving the management area (A3) is the second attribute information, the control unit (314) performs the second process.

[0136] According to the above configuration, the control unit (314) can perform the first process or the second process depending on the attribute information.

[0137] Furthermore, in the security system (3) according to the fourth aspect, in the second aspect, when the attribute information corresponding to the user (U1) leaving the managed area (A3) is the first attribute information, the control unit (314) performs the first process. When the attribute information corresponding to the user (U1) leaving the managed area (A3) is the second attribute information and there is a person in the managed area (A3) even when the user (U1) leaves the managed area (A3), the control unit (314) performs the second process. When the attribute information corresponding to the user (U1) leaving the managed area (A3) is the second attribute information and there is no person in the managed area (A3) when the user (U1) leaves the managed area (A3), the control unit (314) performs the first process.

[0138] According to the above configuration, the control unit (314) can perform the first process or the second process depending on the attribute information and the presence or absence of a person.

[0139] Furthermore, in the security system (3) according to the fifth aspect, in the second aspect, when the attribute information corresponding to the user (U1) leaving the managed area (A3) is the first attribute information and there is a person in the managed area (A3) even when the user (U1) leaves the managed area (A3), the control unit (314) performs the second processing. When the attribute information corresponding to the user (U1) leaving the managed area (A3) is the first attribute information and there is no person in the managed area (A3) when the user (U1) leaves the managed area (A3), the control unit (314) performs the first processing. When the attribute information corresponding to the user (U1) leaving the managed area (A3) is the second attribute information, the control unit (314) performs the second processing.

[0140] According to the above configuration, the control unit (314) can perform the first process or the second process depending on the attribute information and the presence or absence of a person.

[0141] In addition, in the security system (3) according to a sixth aspect, in any one of the third to fifth aspects, the first attribute information includes attribute information indicating that the user (U1) is a child.

[0142] According to the above configuration, the setting is automatically made when the child goes out, thereby reducing the risk of crime.

[0143] In addition, in a security system (3) according to a seventh aspect, in any one of the first to sixth aspects, the positioning accuracy of the measuring device (X2) is 1 m or less.

[0144] According to the above configuration, a highly accurate security system (3) can be provided.

[0145] In addition, in the security system (3) according to an eighth aspect, in any one of the first to seventh aspects, the control unit (314) transmits recommended information to the user terminal (X1) in the second processing.

[0146] According to the above configuration, it is easy to notify the user (U1) of recommended information.

[0147] In addition, in the security system (3) according to the ninth aspect, in any one of the first to eighth aspects, when multiple users (U1) leave the management area (A3) within a certain period of time, the control unit (314) determines whether to perform the first process or the second process based on the user information of the user (U1) who is farthest from the entrance / exit of the management area (A3) among the multiple users (U1).

[0148] According to the above configuration, it is possible to reduce the possibility that a plurality of users (U1) will forget to set security.

[0149] In addition, in the security system (3) according to a tenth aspect, in any one of the first to ninth aspects, a priority is set for each of the multiple users (U1). When the multiple users (U1) leave the management area (A3) within a certain time, the control unit (314) determines whether to perform the first process or the second process according to the user information of the user (U1) with the highest priority among the multiple users (U1).

[0150] According to the above configuration, a highly convenient security system (3) can be provided.

[0151] The configurations other than the first aspect are not essential for the security system (3) and can be omitted as appropriate.

[0152] A security method according to an eleventh aspect performs security management in a managed area (A3). The security method includes a first acquisition step, a second acquisition step, a determination step, and a control step. The first acquisition step acquires location information of a user (U1) measured by a measurement device (X2) based on a signal transmitted from a user terminal (X1) owned by the user (U1). The second acquisition step acquires user information for distinguishing the user (U1). The determination step determines, based on the location information, a situation in which the user (U1) leaves the managed area (A3) and a situation in which the user (U1) enters the managed area (A3). The control step performs a first process of controlling the setting or release of security for the managed area (A3) or a second process of notifying the user (U1) of recommendation information recommending the setting or release of security when the situation determined in the determination step is at least one of a situation in which the user (U1) leaves the managed area (A3) and a situation in which the user (U1) enters the managed area (A3). The control step determines whether to perform the first process or the second process according to the user information.

[0153] According to the above configuration, a highly convenient security method can be provided.

[0154] A program according to a twelfth aspect is a program readable by a computer system, and causes one or more processors of the computer system to execute the security method according to the eleventh aspect.

[0155] According to the above configuration, a highly convenient security method can be provided by a program.

[0156] Not limited to the above aspects, various configurations (including modified examples) of the security system (3) according to each embodiment can be embodied as a security method, a (computer) program, or a non-transitory recording medium on which a program is recorded.
