(Embodiment)
[Notification system configuration]
First, the configuration of a notification system according to an embodiment will be described. Fig. 1 is a block diagram showing the functional configuration of a notification system according to an embodiment.

The notification system 10 shown in FIG. 1 is a system that can notify users that an aftermarket electric lock 20, which is attached to an existing door of a facility 80, has detached from the door and that the installation of the electric lock 20 is poor. Hereinafter, the detachment of the electric lock 20 from the door and the poor installation of the electric lock 20 will be abbreviated as "detachment of the electric lock 20, etc." The notification system 10 includes the electric lock 20, a control system 30, a security system 40, a mobile terminal 50, and an information terminal 60.

First, the electric lock 20 will be described with reference to Figures 2 and 3 in addition to Figure 1. Figure 2 is a diagram for explaining the attachment of the electric lock 20 to a door (view of the door from the indoor side). Figure 2(a) shows the electric lock 20 before it is attached to the door 81, and Figure 2(b) shows the electric lock 20 after it has been attached to the door. Figure 3 is a block diagram showing the functional configuration of the electric lock 20.

The electric lock 20 is detachably attached to an existing door 81 of a facility 80 to provide the door with an authentication function using an authentication medium such as a mobile phone or IC card, or a biometric authentication function. As shown in FIG. 2 , the electric lock 20 is attached to the existing door 81 so as to cover the thumb turn 82 of the door 81 with an adhesive such as double-sided tape. The door 81 is, for example, a door installed at an entrance to the facility 80, and more specifically, the front door or back door of the facility 80.

As shown in Figures 2 and 3, the electric lock 20 includes an authentication unit 21, an information processing unit 22, a memory unit 23, a retractable mechanism 24, a drive unit 25, a communication unit 26, a battery 27, and a housing 28.

The authentication unit 21 acquires authentication information from an authentication medium, such as a mobile phone or IC (Integrated Circuit) card, by performing short-range wireless communication with the authentication medium. The authentication unit 21 is implemented, for example, by a wireless communication circuit such as an RFID (Radio Frequency Identification) reader. The authentication unit 21 may also acquire biometric authentication information from users of the facility 80. In this case, the authentication unit 21 is implemented by a biometric sensor such as a fingerprint sensor.

When the authentication unit 21 acquires authentication information (or biometric authentication information) that matches the registration information, the information processing unit 22 drives the drive unit 25 (i.e., locks or unlocks the electric lock 20). Specifically, the information processing unit 22 drives the drive unit 25 by outputting a control signal to the drive unit 25. The information processing unit 22 is implemented, for example, by a microcomputer, but may also be implemented by a processor. The information processing unit 22 also includes, as a functional component, a detection unit 29 that detects when the electric lock 20 is removed, etc.

The functions of the information processing unit 22 (including the functions of the detection unit 29) are realized, for example, by a microcomputer or processor constituting the information processing unit 22 executing a computer program stored in the memory unit 23.

The memory unit 23 is a storage device that stores registration information used to verify authentication information, computer programs executed by the information processing unit 22, and the like. The memory unit 23 is realized, for example, by semiconductor memory.

The retraction mechanism 24 is a mechanism that allows the detection unit 29 to detect the removal of the electric lock 20, etc. Figure 4 shows an example configuration of the retraction mechanism 24, with Figure 4(a) showing the retraction mechanism 24 when the electric lock 20 is properly attached to the door 81, and Figure 4(b) showing the retraction mechanism 24 when the electric lock 20 is not properly attached. Note that Figure 4 is a schematic cross-sectional view of the electric lock 20.

The retraction mechanism 24 includes, for example, an elastic member 24x such as a spring, a protrusion 24y biased by the elastic member 24x so as to protrude from the housing 28 to the outside of the housing 28, and a sensor (not shown).

More specifically, the protrusion 24y protrudes toward the door 81 from the surface of the housing 28 that faces the door 81 when attached. As shown in Figure 4(a), when the electric lock 20 is properly attached to the door 81, the protrusion 24y is pushed by the door 81 and is housed inside the housing 28 against the elastic force of the elastic member 24x. As shown in Figure 4(b), when the electric lock 20 is not properly attached to the door 81, the protrusion 24y protrudes outside the housing 28. Although not shown, the protrusion 24y also protrudes outside the housing 28 when the electric lock 20 is detached from the door 81.

The sensor included in the retraction mechanism 24 senses the displacement (protrusion) of the protrusion 24y and outputs the sensing result to the detection unit 29. In this way, the retraction mechanism 24 can be used to detect, for example, the removal of the electric lock 20 from the door 81.

The drive unit 25 is a drive mechanism (including a circuit) connected to the thumb turn 82. The drive unit 25 has an electric motor, a drive circuit for the electric motor, and a transmission mechanism that transmits the driving force of the electric motor to the thumb turn 82 of the door 81. The electric motor is powered by power supplied from the battery 27, and the driving force of the electric motor is transmitted to the thumb turn 82 via the transmission mechanism, moving the deadbolt of the door 81 to the locked or unlocked position.

The communication unit 26 is composed of at least one of a communication circuit (communication module) that allows the electric lock 20 to communicate with other devices via a local communication network, and a communication circuit (communication module) that allows the electric lock 20 to communicate with other devices via a wide area communication network such as the Internet. The communication unit 26 communicates with, for example, the device controller 31 and security controller 41 via the local communication network, and with the device control server 36 via the wide area communication network. The communication unit 26 performs, for example, wireless communication. There are no particular limitations on the communication standard used for communication by the communication unit 26.

The battery 27 is the power source for the electric lock 20 and supplies power to the authentication unit 21, information processing unit 22, memory unit 23, sensors of the retraction mechanism 24, and drive unit 25. Specifically, the battery 27 is a primary battery such as a dry cell battery, but may also be a secondary battery.

The housing 28 houses the authentication unit 21, information processing unit 22, memory unit 23, retractable mechanism 24, drive unit 25, communication unit 26, and battery 27. The housing 28 is formed, for example, from a resin material, but may also be formed from a metal material.

[Control system configuration]
Next, the control system 30 will be described with reference to Fig. 1. The control system 30 is, for example, a system provided by a business operator such as a home appliance manufacturer to operate an appliance control service, and is a system that allows users of a facility 80 to control appliances (not shown) such as air conditioning appliances or lighting appliances installed in the facility 80. The control system 30 includes an appliance controller 31 installed within the facility 80 and an appliance control server 36 installed outside the facility 80.

First, the device controller 31 will be described. The device controller 31 is, for example, an EMS (Energy Management System) controller with energy management functionality. It is installed within the facility 80 and manages the power consumption of the devices installed within the facility 80. The device controller 31 also controls the devices installed within the premises of the facility 80. The device controller 31 is not limited to an EMS controller, and may be another home controller without energy management functionality, or a gateway device. The device controller 31 includes a communication unit 32, an information processing unit 33, and a memory unit 34.

The communication unit 32 is composed of a communication circuit (communication module) that allows the device controller 31 to communicate with other devices via a local communication network, and a communication circuit (communication module) that allows the device controller 31 to communicate with other devices via a wide area communication network such as the Internet. The communication unit 32 communicates with, for example, the electric lock 20 and the security controller 41 via the local communication network, and with the device control server 36 via the wide area communication network. The communication unit 32 may perform wireless communication or wired communication. There are no particular limitations on the communication standard used by the communication unit 32.

The information processing unit 33 processes information related to device control and information related to notifications such as the removal of the electric lock 20. The information processing unit 33 is implemented, for example, by a microcomputer, but may also be implemented by a processor or dedicated circuit. The information processing unit 33 includes, as functional components, an acquisition unit 33a and an output unit 33b. The functions of the acquisition unit 33a and the output unit 33b are realized when the microcomputer or processor constituting the information processing unit 33 executes a computer program stored in the memory unit 34.

The memory unit 34 is a storage device that stores computer programs executed by the information processing unit 33. The memory unit 34 is realized, for example, by semiconductor memory.

Next, we will explain the device control server 36. The device control server 36 communicates with the security server 46 so that the control system 30 can cooperate with the security system 40. The device control server 36 includes a communication unit 37, an information processing unit 38, and a memory unit 39.

The communication unit 37 is a communication circuit (communication module) that enables the device control server 36 to communicate with the device controller 31, security server 46, mobile terminal 50, and information terminal 60 via a wide area communication network such as the Internet. The communication unit 37 is, for example, a wired communication circuit that performs wired communication, but may also be a wireless communication circuit that performs wireless communication. There are no particular limitations on the communication standard used for communication by the communication unit 37.

The information processing unit 38 processes information related to notifications such as the removal of the electric lock 20. The information processing unit 38 is implemented, for example, by a microcomputer, but may also be implemented by a processor or dedicated circuit. The information processing unit 38 includes, as functional components, an acquisition unit 38a and an output unit 38b. The functions of the acquisition unit 38a and the output unit 38b are realized when the microcomputer or processor constituting the information processing unit 38 executes a computer program stored in the memory unit 39.

The memory unit 39 is a storage device that stores computer programs executed by the information processing unit 38. The memory unit 39 is realized, for example, by an HDD (Hard Disk Drive), but may also be realized by semiconductor memory.

[Security system configuration]
Next, the security system 40 will be described with reference to FIG. 1. The security system 40 is a system provided by a business operator (hereinafter also referred to as a service operator) that operates a home security service or the like. The security system 40 is, for example, a crime prevention system that performs information processing to notify the outside of the facility 80 that a security abnormality has occurred in the facility 80. Specifically, the security system 40 includes a security controller 41, a sensor 45, and a security server 46. First, the security controller 41 will be described.

When the security controller 41 detects an intruder into the facility 80 using the sensor 45 while the alert mode is active, it assumes that an abnormality has occurred in the facility 80 and transmits (outputs) alarm information to the security server 46 (outside the facility 80). When a user of the facility 80 leaves the facility 80, the user can set the security system 40 to alert mode (in other words, enable alert mode) by performing an operation such as inserting a specified authentication medium into the security controller 41. The security controller 41 includes a communication unit 42, an information processing unit 43, and a memory unit 44.

The communication unit 42 is composed of a communication circuit (communication module) that allows the security controller 41 to communicate with other devices via a local communication network, and a communication circuit (communication module) that allows the security controller 41 to communicate with other devices via a wide area communication network such as the Internet. The communication unit 42 communicates with, for example, the electric lock 20, the device controller 31, and the sensor 45 via the local communication network, and with the security server 46 via the wide area communication network. The communication unit 42 may perform wireless communication or wired communication. There are no particular limitations on the communication standard used by the communication unit 42.

The information processing unit 43 performs information processing to notify the occurrence of security abnormalities within the premises of facility 80. The information processing unit 43 is implemented, for example, by a microcomputer, but may also be implemented by a processor or dedicated circuit. The information processing unit 43 includes, as functional components, an acquisition unit 43a and an output unit 43b. The functions of the acquisition unit 43a and the output unit 43b are realized when the microcomputer or processor constituting the information processing unit 43 executes a computer program stored in the memory unit 44.

The memory unit 44 is a storage device that stores computer programs executed by the information processing unit 43. The memory unit 44 is realized, for example, by semiconductor memory.

Next, the sensor 45 will be described. The sensor 45 is a sensor for detecting the occurrence of security-related abnormalities in the facility 80. Specifically, the sensor 45 is a security sensor such as a window or door opening/closing sensor, a glass breakage sensor, or a human presence sensor. The security system 40 is required to be equipped with at least one sensor 45, but may also be equipped with multiple sensors 45.

Next, the security server 46 will be described. The security server 46 performs information processing to arrange for a visitor to the facility 80 based on the notification information received from the security controller 41. As a result of this information processing, an operator of the business that operates the security system 40 arranges for the visitor, and the visitor rushes to the facility 80. The operator also reports to the police station or the like as necessary. In the embodiment, the operator refers to a person who operates a computer or the like.

Next, we will explain the mobile terminal 50 and information terminal 60. The mobile terminal 50 is a portable information terminal used by users of the facility 80 (or residents of the facility 80, if the facility 80 is a residence) to receive notifications regarding the removal of the electric lock 20, etc. Specifically, the mobile terminal 50 is a smartphone or tablet terminal, etc.

When the facility 80 is an office building or an apartment building, the information terminal 60 is used by the management company of the facility 80 (more specifically, an employee of the management company) to receive notifications regarding the removal of the electric lock 20, etc. The information terminal 60 is, for example, a personal computer, but may also be a smartphone or tablet terminal.

[Operation example 1]
A retrofit electric lock 20 is more likely to come off the door 81 than an electric lock that is pre-assembled and integrated with the door 81. In addition, retrofit electric locks 20 may be installed by ordinary users, which makes them more likely to be installed poorly on the door 81. As a countermeasure against such cases of the electric lock 20 coming off, the notification system 10 can notify the user of the electric lock 20 coming off. Figure 5 is a sequence diagram of a first example of operation of the notification system 10.

First, the detection unit 29 of the electric lock 20 detects a state corresponding to the detachment of the electric lock 20 (S11). As described above, when the electric lock 20 is properly attached to the door 81, the protrusion 24y of the retraction mechanism 24 provided in the electric lock 20 is pushed by the door 81 and is housed within the housing 28 against the elastic force (biasing force) of the elastic member 24x. When the electric lock 20 is detached from the door 81 or when the electric lock 20 is not properly attached to the door 81, the force applied from the door 81 to the protrusion 24y decreases, and the elastic force of the elastic member 24x causes the protrusion 24y to protrude outside the housing 28. The detection unit 29 detects the protruding state of the protrusion 24y based on the sensing results of the sensor provided in the retraction mechanism 24. In other words, the detection unit 29 can use the retraction mechanism 24 (protrusion 24y) to detect a state corresponding to the detachment of the electric lock 20 (a state in which the protrusion 24y protrudes).

Furthermore, when the detection unit 29 detects a state equivalent to detachment, etc. (the protrusion 24y protrudes), it outputs first information as the detection result (S12).

The first information indicates that the electric lock 20 has come off the door 81 or that the electric lock 20 is not properly attached to the door 81. The first information includes identification information for the electric lock 20. The identification information for the electric lock 20 may be, for example, the device ID of the electric lock 20.

The detection unit 29 causes the communication unit 26 to transmit the output first information to the device controller 31. In other words, the communication unit 26 transmits the output first information to the device controller 31 (S13).

The communication unit 32 of the device controller 31 receives the first information. The acquisition unit 33a acquires the received first information (S14), and the output unit 33b outputs the second information upon acquisition of the first information (S15).

The second information is information for notifying the user that the electric lock 20 has been removed from the door 81 or that the electric lock 20 is not properly attached to the door 81. The second information includes identification information for the device controller 31. The second information may also include identification information for the electric lock 20 that was included in the first information. The output unit 33b causes the communication unit 32 to transmit the second information output in step S15 to the device control server 36. In other words, the communication unit 32 transmits the output second information to the device control server 36 (S16).

The communication unit 37 of the device control server 36 receives the second information. Here, the memory unit 39 of the device control server 36 pre-stores (registers) notification destination information that associates the identification information of the device controller 31 with the identification information of the mobile terminal 50 to be notified. The identification information of the mobile terminal 50 is, for example, the ID of a notification application program installed on the mobile terminal 50.

The acquisition unit 38a acquires the second information (S17), and the output unit 38b outputs the second information in response to the acquisition of the first information (S18). Here, the output unit 38b can determine the mobile device 50 to be notified based on the identification information of the device controller 31 included in the second information acquired in step S17 and the notification destination information described above.

The output unit 38b causes the communication unit 37 to transmit the second information output in step S18 to the selected mobile device 50. In other words, the communication unit 37 transmits the output second information to the mobile device 50 (S19).

The processing of steps S17 to S19 can also be considered to be processing of relaying the second information output by the output unit 33b of the device controller 31 to the mobile terminal 50. In other words, in steps S15 and S16, the output unit 33b can also be considered to be outputting the second information to the mobile terminal 50.

The mobile terminal 50 receives the second information and displays a notification screen based on the received second information (S20). Figure 6 shows an example of the notification screen displayed on the mobile terminal 50. The notification screen notifies the user of the facility 80 who is carrying the mobile terminal 50 that the electric lock 20 has been removed, etc.

As described above, the notification system 10 includes an acquisition unit 33a that acquires first information regarding the removal of the electric lock 20, and an output unit 33b that outputs second information for notifying users of the electric lock 20 based on the acquired first information. Specifically, the output unit 33b outputs the second information to the mobile device 50 of the user of the facility 80.

Such a notification system 10 can notify users of the facility 80 (or residents of the facility 80, if the facility 80 is a residence) of the removal of the electric lock 20, etc. The notification system 10 can prevent problems from occurring due to the removal of the electric lock 20, etc.

In operation example 1, the notification destination is not limited to the mobile device 50 of the user of facility 80. For example, the output unit 33b may output the second information to the information terminal 60 of the management company of facility 80.

In this case, notification destination information in which the identification information of the device controller 31 and the identification information of the notification destination information terminal 60 are associated is pre-stored (registered) in the memory unit 39 of the device control server 36. The output unit 38b can determine the notification destination information terminal 60 based on the identification information of the device controller 31 included in the acquired second information and the above-mentioned notification destination information. Therefore, in step S19, the output unit 38b can cause the communication unit 37 to transmit the second information to the determined information terminal 60. As a result, for example, a notification screen is displayed on the display unit provided in the information terminal 60.

The output unit 33b may also output the second information to the security system 40 (security server 46). The security system 40 is an example of a system of a service provider that provides security services to the facility 80.

In this case, in step S19, the output unit 38b causes the communication unit 37 to transmit the second information to the security server 46. As a result, for example, a notification screen is displayed on a display unit provided in an information terminal (not shown) that is communicatively connected to the security server 46.

If the security server 46 associates the identification information of the device controller 31 with information about the user of the facility 80 (such as address or contact information), the service provider can take action in the event of the electric lock 20 being removed. Such action may include, for example, notifying the user of the facility 80 or visiting the facility 80 for repairs.

[Operation example 2]
If the communication unit 26 of the electric lock 20 supports communication via a wide area communication network, the electric lock 20 may transmit the first information to the device control server 36 instead of the device controller 31. Figure 7 is a sequence diagram of an operation example 2 of such a notification system 10.

First, the detection unit 29 of the electric lock 20 detects a state corresponding to the electric lock 20 being detached (S21), and in response to this, outputs first information as the detection result (S22). The processing of steps S21 and S22 is the same as the processing of steps S11 and S12 in operation example 1. The first information includes the identification information of the electric lock 20.

The detection unit 29 also causes the communication unit 26 to transmit the output first information to the device control server 36. In other words, the communication unit 26 transmits the output first information to the device control server 36 (S23).

The communication unit 37 of the device control server 36 receives the first information. Here, the memory unit 39 of the device control server 36 pre-stores (registers) notification destination information that associates the identification information of the electric lock 20 with the identification information of the mobile device 50 to be notified. The identification information of the mobile device 50 is, for example, an ID linked to a notification application program installed on the mobile device 50.

The acquisition unit 38a acquires the first information (S24), and the output unit 38b outputs the second information upon acquisition of the first information (S25). Here, the output unit 38b can determine the mobile device 50 to notify based on the identification information of the electric lock 20 included in the first information acquired in step S24 and the notification destination information described above.

The output unit 38b causes the communication unit 37 to transmit the second information output in step S25 to the selected mobile device 50. In other words, the communication unit 37 transmits the output second information to the mobile device 50 (S26). In other words, it can be said that the output unit 38b outputs the second information to the mobile device 50.

The mobile terminal 50 receives the second information and displays a notification screen like that shown in Figure 6 based on the received second information (S27). The notification screen notifies the user of the facility 80 who is carrying the mobile terminal 50 that the electric lock 20 has been removed, etc.

As described above, the notification system 10 includes an acquisition unit 38a that acquires first information regarding the removal of the electric lock 20, and an output unit 38b that outputs second information for notifying users of the electric lock 20 based on the acquired first information. Specifically, the output unit 38b outputs the second information to the mobile device 50 of the user of the facility 80.

Such a notification system 10 can notify users of the facility 80 (or residents of the facility 80, if the facility 80 is a residence) of the removal of the electric lock 20, etc. The notification system 10 can prevent problems from occurring due to the removal of the electric lock 20, etc.

In operation example 2, the notification destination is not limited to the mobile device 50 of the user of facility 80. For example, the output unit 38b may output the second information to the information terminal 60 of the management company of facility 80.

In this case, notification destination information that associates the identification information of the electric lock 20 with the identification information of the information terminal 60 to be notified is pre-stored (registered) in the memory unit 39 of the device control server 36. The output unit 38b can determine the information terminal 60 to be notified based on the identification information of the electric lock 20 included in the acquired first information and the above-mentioned notification destination information. Therefore, in step S26, the output unit 38b can cause the communication unit 37 to transmit the second information to the determined information terminal 60. As a result, for example, a notification screen is displayed on the display unit provided in the information terminal 60.

The output unit 38b may also output the second information to the security system 40 (security server 46). The security system 40 is an example of a system of a service provider that provides security services to the facility 80.

In this case, in step S26, the output unit 38b causes the communication unit 37 to transmit the second information to the security server 46. As a result, for example, a notification screen is displayed on a display unit provided in an information terminal (not shown) that is communicatively connected to the security server 46.

If the security server 46 associates the identification information of the electric lock 20 with information about the user of the facility 80 (such as address or contact information), the service provider can take action in the event of the electric lock 20 being removed. Such action may include, for example, notifying the user of the facility 80 or visiting the facility 80 for repairs.

[Operation example 3]
The electric lock 20 may also transmit the first information to the security controller 41. Fig. 8 is a sequence diagram of an operation example 3 of the notification system 10.

First, the detection unit 29 of the electric lock 20 detects a state corresponding to the electric lock 20 being detached (S31), and in response to this, outputs first information as the detection result (S32). The processing of steps S31 and S32 is the same as the processing of steps S11 and S12 in operation example 1. The first information includes the identification information of the electric lock 20.

The detection unit 29 also causes the communication unit 26 to transmit the output first information to the security controller 41. In other words, the communication unit 26 transmits the output first information to the security controller 41 (S33).

The communication unit 42 of the security controller 41 receives the first information. The acquisition unit 43a acquires the received first information (S34), and the output unit 43b outputs the second information upon acquisition of the first information (S35).

The second information is information for notifying the service provider that the electric lock 20 has been removed from the door 81 or that the electric lock 20 is not properly attached to the door 81. The second information includes identification information for the security controller 41. The second information may also include identification information for the electric lock 20 that was included in the first information. The output unit 43b causes the communication unit 42 to transmit the second information output in step S35 to the security server 46. In other words, the communication unit 42 transmits the output second information to the security server 46 (S36). The communication unit 47 of the security server 46 receives the second information. As a result, for example, a notification screen is displayed on a display unit provided on an information terminal (not shown) that is communicatively connected to the security server 46. The processing of steps S35 and S36 can be rephrased as notification processing to the service provider regarding the removal of the electric lock 20, etc.

The memory unit 49 of the security server 46 associates the identification information of the security controller 41 with information about the user of the facility 80 (such as address or contact information). When the second information is received by the security server 46, the service provider can take action in response to the removal of the electric lock 20. The action taken here may include, for example, notifying the user of the facility 80 or visiting the facility 80 (to repair the electric lock 20).

As described above, the notification system 10 includes an acquisition unit 43a that acquires first information regarding the removal of the electric lock 20, and an output unit 43b that outputs second information for notifying the removal of the electric lock 20 based on the acquired first information. Specifically, the output unit 43b outputs the second information to the system (security system 40; in other words, the security server 46) of the service provider that provides security services to the facility 80.

This notification system 10 can notify the service provider of events such as the removal of the electric lock 20. The notification system 10 can prevent problems caused by events such as the removal of the electric lock 20.

In operation example 3, the notification destination is not limited to the security server 46. For example, the output unit 43b may output the second information to the mobile terminal 50 of a user of the facility 80.

In this case, notification destination information that associates the identification information of the security controller 41 with the identification information of the information terminal 60 to be notified is pre-stored (registered) in the security server 46. The security server 46 can determine the mobile terminal 50 to be notified based on the identification information of the security controller 41 included in the acquired second information and the above-mentioned notification destination information. Therefore, after step S36, the security server 46 can transmit the second information to the determined mobile terminal 50. As a result, for example, a notification screen is displayed on the display unit of the mobile terminal 50.

The output unit 43b may also output the second information to the information terminal 60 of the management company of the facility 80. In this case, notification destination information in which the identification information of the security controller 41 is associated with the identification information of the information terminal 60 to be notified is pre-stored (registered) in the security server 46. The security server 46 can determine the information terminal 60 to be notified based on the identification information of the security controller 41 included in the acquired second information and the above-mentioned notification destination information. Therefore, after step S36, the security server 46 can transmit the second information to the determined information terminal 60. As a result, for example, a notification screen is displayed on the display unit provided in the information terminal 60.

[Modification 1 of electric lock]
In the above embodiment, the detection unit 29 of the electric lock 20 detects a state equivalent to the detachment of the electric lock 20 using the retraction mechanism 24, but the detection unit 29 may also detect a state equivalent to the detachment of the electric lock 20 using a different method. Below, an electric lock according to Modification 1 will be described, which detects a state equivalent to the detachment of the electric lock using components other than the retraction mechanism 24. Figure 9 is a block diagram showing the functional configuration of the electric lock according to Modification 1.

The electric lock 20a according to variant 1 shown in Figure 9 has an infrared light module 24a instead of the retractable mechanism 24.

The infrared light module 24a emits infrared light (infrared rays) and receives the emitted infrared light reflected by the door 81. The infrared light module 24a includes a light-emitting element that emits infrared light toward the door 81 when the electric lock 20a is attached to the door 81, and a light-receiving element that receives the infrared light emitted by the light-emitting element and reflected by the door 81. The light-emitting element is realized, for example, by an LED (Light Emitting Diode) and emits infrared light periodically or steadily. The light-receiving element is realized, for example, by a photodiode. The light-receiving element senses the amount of infrared light received and outputs the sensing result (amount of received light) to the detection unit 29.

When the electric lock 20a is properly attached to the door 81, the amount of infrared light received by the light-receiving element is large. When the electric lock 20a is detached from the door 81 or when the electric lock 20a is not properly attached to the door 81, the amount of infrared light reflected by the door 81 decreases, and therefore the amount of infrared light received by the light-receiving element is small.

The detection unit 29, for example, periodically activates the light-emitting element, monitors the amount of light received by the light-receiving element when the light-emitting element is activated, and detects a state where the amount of received light is below a predetermined value. In other words, the detection unit 29 can use the infrared light module 24a to detect a state equivalent to the electric lock 20a being detached (a state where the amount of received light is reduced). Note that the electric lock 20a can also detect the detachment of the electric lock 20a using visible light or ultrasound instead of infrared light.

The above-described notification system 10 may be equipped with an electric lock 20a instead of the electric lock 20. In other words, in the above-described operation examples 1 to 3, the electric lock 20 may be replaced with the electric lock 20a.

[Modification 2 of electric lock]
The following describes an electric lock according to Modification 2, which detects the removal of the electric lock using components other than the retraction mechanism 24. Fig. 10 is a block diagram showing the functional configuration of the electric lock according to Modification 2. An electric lock 20b according to Modification 2 shown in Fig. 10 includes an acceleration sensor 24b instead of the retraction mechanism 24.

The acceleration sensor 24b senses the acceleration (an example of an external force) occurring in the electric lock 20b and outputs the sensing result to the detection unit 29.

When electric lock 20b detaches from door 81 and hits the ground, electric lock 20b experiences a large acceleration (is subjected to an impact). Furthermore, if an attempt is made to forcibly remove electric lock 20b, electric lock 20b also experiences a relatively large acceleration. Therefore, detection unit 29 monitors the sensing results of acceleration sensor 24b and detects a state in which electric lock 20b experiences acceleration equal to or greater than a predetermined value. In other words, detection unit 29 can use acceleration sensor 24b to detect a state equivalent to electric lock 20b detaching (a state in which an external force is applied to electric lock 20b).

The electric lock 20b may be equipped with a sensor that senses external forces acting on the electric lock 20b. Examples of such sensors include an acceleration sensor 24b, a gyro sensor, or a vibration sensor. The electric lock 20b may output the first information when an external force greater than or equal to a predetermined value is applied to the electric lock 20b.

The above-described notification system 10 may include electric lock 20b instead of electric lock 20. In other words, in the above-described operation examples 1 to 3, electric lock 20 may be read as electric lock 20b.

[Electric Lock Variation 3]
The following describes an electric lock according to Modification 3, which detects the removal of the electric lock using components other than the retraction mechanism 24. Fig. 11 is a block diagram showing the functional configuration of the electric lock according to Modification 3. The electric lock 20c according to Modification 3 shown in Fig. 11 includes a current sensor 24c instead of the retraction mechanism 24.

The current sensor 24c senses the current (hereinafter also referred to as the drive current) that flows through the electric motor when the drive unit 25 is driven (the thumb turn 82 is turned) to lock or unlock the door 81, and outputs the sensing result (current value) to the detection unit 29. The current sensor 24c may be incorporated into the drive unit 25.

When the electric lock 20c is properly attached to the door 81, the drive current value will be within a specified range. In contrast, if the electric lock 20c is improperly attached to the door 81 and the drive unit 25 and thumb turn 82 are connected but the connection is poor, a greater force (torque) than normal will be required to turn the thumb turn 82. In other words, the drive current will rise above the specified range.

Furthermore, if the electric lock 20c is improperly attached to the door 81 and the drive unit 25 is not connected to the thumb turn 82, or if the electric lock 20c is detached from the door 81, there will be no resistance when turning the thumb turn 82, and the drive current will fall below the specified range.

The detection unit 29 therefore monitors the sensing results of the current sensor 24c and detects a state in which the current value of the drive current is outside a predetermined range. In other words, the detection unit 29 can use the current sensor 24c to detect a state equivalent to the electric lock 20c being detached (a state in which the current value of the drive current is outside a predetermined range).

The above-described notification system 10 may be equipped with electric lock 20c instead of electric lock 20. In other words, in the above-described operation examples 1 to 3, electric lock 20 may be replaced with electric lock 20c.

[Modification 4 of the electric lock]
The following describes an electric lock according to Modification 4, which detects the removal of the electric lock using components other than the retractable mechanism 24. Fig. 12 is a diagram showing a wire connecting the electric lock according to Modification 4 to the door 81. Fig. 13 is a block diagram showing the functional configuration of the electric lock according to Modification 4.

As shown in FIG. 12, one end of the wire 70 is attached to the door 81, and the other end of the wire 70 is attached to the electric lock 20d according to variant 4. The connection between the electric lock 20d and the door 81 by the wire 70 is made at the same time as the electric lock 20d is attached to the door 81.

Here, one end of the wire 70 is firmly attached to the door 81 using at least one of adhesive, a magnet, and a screw. Therefore, even if the electric lock 20d is detached, the one end of the wire 70 will not come off the door 81.

In contrast, the other end of wire 70 is attached so that it can be easily detached when the weight of electric lock 20d is applied. For example, the other end of wire 70 is fitted with a plug (or a similar structure) used for a microphone or earphone, and electric lock 20d is provided with a jack into which the plug can be inserted or removed.

As shown in Figure 13, the electric lock 20d is equipped with a wire sensor 24d instead of the retractable mechanism 24. The wire sensor 24d senses when the plug attached to the other end of the wire 70 is removed from the jack attached to the electric lock 20d, and outputs the sensing result to the detection unit 29. The wire sensor 24d is realized, for example, by a circuit, and senses whether the electrical connection between the jack and plug is on or off.

When the electric lock 20d is detached from the door 81, the other end of the wire 70 becomes detached from the electric lock 20d. The detection unit 29 monitors the sensing results of the wire sensor 24d and detects the state in which the other end of the wire 70 has become detached from the electric lock 20d. In other words, the detection unit 29 can use the wire sensor 24d to detect a state equivalent to the detachment of the electric lock 20d (the state in which the other end of the wire 70 has become detached from the electric lock 20d).

The above-described notification system 10 may be equipped with electric lock 20d instead of electric lock 20. In other words, in the above-described operation examples 1 to 3, electric lock 20 may be replaced with electric lock 20d.

[Modification 5 of the electric lock]
The following describes an electric lock according to Modification 5, which detects the removal of the electric lock or the like using components other than the retractable mechanism 24. Fig. 14 is a schematic cross-sectional view showing the configuration of the electric lock according to Modification 5.

As shown in FIG. 14, the electric lock 20e according to variant 5 comprises a first main body 20e1 and a second main body 20e2. The first main body 20e1 is located on the thumb turn 82 side of the door 81 and incorporates at least the drive unit 25 and the first wireless communication unit 24e1. The second main body 20e2 is located on the cylinder 83 side of the door 81 and incorporates at least the authentication unit 21 and the second wireless communication unit 24e2. Although not shown, the electric lock 20e, like the electric lock 20, also comprises an information processing unit 22 (including the detection unit 29), a memory unit 23, a communication unit 26, and a battery 27, and these components are housed in either the first main body 20e1 or the second main body 20e2.

A door 81 is located between the first main body unit 20e1 and the second main body unit 20e2. In this state, the first wireless communication unit 24e1 and the second wireless communication unit 24e2 communicate periodically or steadily. The communication range of the first wireless communication unit 24e1 and the second wireless communication unit 24e2 is limited, and if either the first main body unit 20e1 or the second main body unit 20e2 is removed from the door 81, the first wireless communication unit 24e1 and the second wireless communication unit 24e2 will no longer be able to communicate.

The detection unit 29 therefore periodically wirelessly transmits a signal from one of the first wireless communication unit 24e1 and the second wireless communication unit 24e2 to the other, and detects a state in which no response to the signal is received from the other of the first wireless communication unit 24e1 and the second wireless communication unit 24e2. In other words, based on the wireless communication states of the first wireless communication unit 24e1 and the second wireless communication unit 24e2, the detection unit 29 can detect a state in which wireless communication between the first wireless communication unit 24e1 and the second wireless communication unit 24e2 is impossible as a state corresponding to the electric lock 20e being detached, etc.

In this case, one of the first wireless communication unit 24e1 and the second wireless communication unit 24e2 is implemented by a wireless communication circuit that actively communicates, but the other of the first wireless communication unit 24e1 and the second wireless communication unit 24e2 may be implemented by a wireless communication circuit that actively communicates or a wireless communication circuit that passively communicates. For example, one of the first wireless communication unit 24e1 and the second wireless communication unit 24e2 may be implemented by an RFID reader, and the other of the first wireless communication unit 24e1 and the second wireless communication unit 24e2 may be implemented by an RFID tag (passive tag).

In addition, the detection unit 29 may detect a state in which the received signal strength drops below a predetermined value as a state corresponding to the detachment of the electric lock 20e, based on the received signal strength at the other of the first wireless communication unit 24e1 and the second wireless communication unit 24e2 when a signal is wirelessly transmitted from one of the first wireless communication unit 24e1 and the second wireless communication unit 24e2 to the other.

The above-described notification system 10 may be equipped with electric lock 20e instead of electric lock 20. In other words, in the above-described operation examples 1 to 3, electric lock 20 may be read as electric lock 20e.

[Other Modifications]
In the above-described operation examples 1 to 3 of the embodiment, notification of the electric lock 20's removal, etc., was performed using the device control server 36 or the security server 46. However, notification of the electric lock 20's removal, etc., may be performed using a dedicated server for notification or another server, such as a server managed by another business, instead of the device control server 36 or the security server 46. The same applies to notification of the electric locks 20a to 20e's removal, etc. Note that the other business refers to a business other than the business that operates the device control service and the business that operates the home security service.

Furthermore, in addition to or instead of the methods described in Operational Examples 1 to 3, notification of the electric lock 20's removal or the like may be achieved by the electric lock 20 itself emitting a sound. In this case, the electric lock 20 is provided with a sound output unit such as a speaker or buzzer inside the housing 28, and the detection unit 29 causes the sound output unit to emit a sound when it detects a state corresponding to the electric lock 20's removal or the like. In this way, notification of the electric lock 20's removal or the like is achieved to people located within the facility 80. Notification of the removal or the like of electric locks 20a to 20e may also be achieved by the sound output unit provided in the electric lock.

In the above embodiment, the security system 40 was described as a crime prevention system, but it may also be a disaster prevention system. In this case, for example, when the security controller 41 detects a fire or other incident at the facility 80 using the sensor 45 while the alert mode is active, it assumes that an abnormality has occurred at the facility 80 and notifies the security server 46 of this. The operator of the business that operates the security system 40 then arranges for a visitor to rush to the facility 80. The operator also notifies the fire department or the like as necessary. In this case, the sensor 45 may be a heat sensor, smoke sensor, gas leak sensor, or the like.

The security system 40 may also be a monitoring system. In this case, when the alert mode is enabled, the security controller 41 uses sensors 45 to monitor the health status of the elderly people residing in the facility 80, and if it detects an abnormality, it notifies the security server 46. An operator of the business that operates the security system 40 then arranges for a visitor to come to the facility 80. The operator also contacts the elderly person's family (for example, a family member living far away). In this case, the sensor 45 may be a monitoring sensor or a vital sign sensor.

[Effects, etc.]
As described above, the notification system 10 is detachably attached to the door 81 provided at the entrance/exit of the facility 80 and comprises an acquisition unit 33a (acquisition unit 38a, acquisition unit 43a) that acquires first information regarding the detachment of the electric lock 20 from the door 81, which controls the locking and unlocking of the door 81, or a poor installation state of the electric lock 20 on the door 81, and an output unit 33b (output unit 38b, output unit 43b) that outputs second information to notify the user regarding the detachment of the electric lock 20 from the door 81 or a poor installation state of the electric lock 20 on the door 81 based on the acquired first information.

Such an electric lock 20 can detect when the electric lock 20 is detached, etc. The electric lock 20 can assist in correcting the installation status of the electric lock 20 on the door.

The electric lock 20 also has a protrusion 24y that is housed within the housing 28 of the electric lock 20 when the electric lock 20 is attached to the door 81, and that protrudes outward from the housing 28 when the electric lock 20 is detached from the door 81 or when the electric lock is not properly attached to the door 81. The detection unit 29 outputs first information when the protrusion 24y protrudes.

Such an electric lock 20 can detect the removal of the electric lock 20 using the retraction mechanism 24.

The electric lock 20a also includes a light-emitting element that emits infrared light toward the door 81 when the electric lock 20a is attached to the door 81, and a light-receiving element that receives the infrared light emitted by the light-emitting element and reflected by the door 81.

Such an electric lock 20c can detect the removal of the electric lock 20c based on the driving current of the electric lock 20c.

Furthermore, electric lock 20d is equipped with a wire sensor 24d that senses when wire 70 connecting electric lock 20d to door 81 becomes detached from electric lock 20d. Detector 29 outputs first information when wire 70 becomes detached from electric lock 20d.
