[0008] [Figure 1] This diagram shows the overall configuration of one embodiment of the present invention. [Figure 2] This is a functional block diagram of a control device according to one embodiment of the present invention. [Figure 3] This is a sequence diagram of the processing of the door open status display system according to the first embodiment of the present invention. [Figure 4] This is a sequence diagram of the processing of the door open status display system according to the second embodiment of the present invention. [Figure 5] This is a sequence diagram of the processing of the door open status display system according to the third embodiment of the present invention. [Figure 6] This is a sequence diagram of the processing of the door open status display system according to the fourth embodiment of the present invention. [Modes for carrying out the invention]

[0009] Embodiments of the present invention will be described below with reference to the drawings.

[0010] <Overall Structure> Figure 1 shows the overall configuration according to one embodiment of the present invention. The door open status display system 1 includes a control device 10, a door sensor 21, a key sensor 22, a contact sensor 23, and a display device 30. The control device 10 can acquire information detected by the door sensor 21, the key sensor 22, and the contact sensor 23. The control device 10 can also display the open status of the door while the door is unlocked and the person is out on the display device 30. Each of these will be described below.

[0011] <<Control device>> When the control device 10 detects that the door is unlocked after being closed and someone touches the handle on the outdoor side of the door (i.e., it is presumed that someone is trying to open the unlocked door), the control device 10 causes the display device 30 to display that the door is presumed to have been opened. The control device 10 is composed of one or more computers. In this way, since the display is performed in response to contact with the handle on the outdoor side of the door while it is unlocked, the display can be made only when the door is opened from the outside (i.e., when the door is opened from the inside, it is excluded).

[0012] <<Door sensor>> The door sensor 21 is a sensor that detects the opening and closing of the door (i.e., the door being opened and the door being closed).

[0013] Here, the door will be described. The door can be any type of door (e.g., a hinged door, a sliding door). For example, the door can be the door of the entrance of any building (e.g., a house, an office) (e.g., the entrance of a detached house, the entrance of each residence in an apartment building). Note that the door can also be the door of a room inside the building.

[0014] <<Key sensor>> The key sensor 22 is a sensor that detects the locking and unlocking of the door key (i.e., the door key being locked and the door key being unlocked). Note that any known technique can be applied to detect how the key is locked and unlocked.

[0015] Here, the key will be described. The key can be any key (e.g., a mechanical key, an electronic key).

[0016] <<Contact sensor>> The contact sensor 23 is a sensor that detects contact with the handle on the outdoor side of the door (e.g., the outside of a house, the outside of an office). Note that how the contact sensor 23 is installed on the handle is a design matter when implementing the present invention, and any known technique can be applied to detect how the contact sensor 23 detects contact.

[0017] Here, the handle will be described. The handle is a part for gripping with the hand when opening and closing the door, and is also called a doorknob.

[0018] <<Display device>> The display device 30 is a device (e.g., an LED light) that is installed on the outdoor side (or in the vicinity thereof) of the door and displays the door opening status. Specifically, the display device 30 lights up or goes out according to an instruction from the control device 10.

[0019] <Functional block> [[ID=I2]]FIG. 2 is a functional block diagram of the control device 10 according to an embodiment of the present invention. The control device 10 can include a door sensor information acquisition unit 101, a key sensor information acquisition unit 102, a contact sensor information acquisition unit 103, a determination unit 104, and a display control unit 105. The control device 10 can function as the door sensor information acquisition unit 101, the key sensor information acquisition unit 102, the contact sensor information acquisition unit 103, the determination unit 104, and the display control unit 105 by executing a program. Hereinafter, each will be described.

[0020] The door sensor information acquisition unit 101 acquires information on the opening and closing of the door detected by the door sensor 21.

[0021] The key sensor information acquisition unit 102 acquires information on the locking and unlocking of the door key detected by the key sensor 22.

[0022] The contact sensor information acquisition unit 103 acquires information on the contact with the outdoor handle of the door detected by the contact sensor 23.

[0023] The determination unit 104 determines whether to start the display on the display device 30 and whether to end the display on the display device 30. Specifically, when the door is in a closed state and the key is in an unlocked state, and the contact sensor 23 detects contact with the outdoor handle of the door, the determination unit 104 determines to start the display on the display device 30.

[0024] Furthermore, the determination unit 104 may decide to start displaying on the display device 30 if, in addition to the contact sensor 23 detecting contact with the handle on the outside of the door (i.e., in addition to the conditions mentioned above), the door sensor 21 detects that the door has changed from a closed state to an open state. In this case, the display can start when the door is actually opened.

[0025] (First Embodiment) The determination unit 104 is configured to start displaying information on the display device 30 when the door is closed and the lock is unlocked, and the contact sensor 23 detects contact with the handle on the outside of the door. However, if a person going out closes the door with their hand on the handle (i.e., the contact sensor 23 detects contact with the handle), the determination unit 104 will start displaying information on the display device 30 because the door is closed, the lock is unlocked, and the contact sensor 23 has detected contact with the handle. To avoid this, the determination unit 104 may prevent the display device 30 from starting to display information even if the door sensor 21 detects that the door is closed immediately after the door sensor 21 detects that the door is open and the contact sensor 23 detects contact.

[0026] (Second embodiment) Furthermore, the determination unit 104 is configured to start displaying information on the display device 30 when the contact sensor 23 detects contact with the handle on the outside of the door while the door is closed and the lock is unlocked. However, when someone who was out touches the handle, the determination unit 104 instructs the display device 30 to start displaying information, but since this display does not actually need to be shown, it should be turned off. Therefore, after the display is shown, when the lock sensor 22 detects that the door is locked (i.e., the person who was out closes and locks the door), the determination unit 104 may instruct the display device 30 to end the display.

[0027] (Third embodiment) The determination unit 104 is configured to start displaying information on the display device 30 when the door is closed and the lock is unlocked, and the contact sensor 23 detects contact with the handle on the outside of the door. However, if someone who was out touches the handle (i.e., the contact sensor 23 detects contact with the handle), the determination unit 104 will start displaying information on the display device 30 because the door is closed, the lock is unlocked, and the contact sensor 23 has detected contact with the handle. To avoid this, the determination unit 104 may be configured not to start displaying information on the display device 30 even if the contact sensor 23 detects contact with the handle, as long as the lock is unlocked and a predetermined time has elapsed since the handle was touched (sufficient time from when the person who was out released their hand from the handle until the door closed), and to start displaying information on the display device 30 after the predetermined time has elapsed.

[0028] (Fourth embodiment) Furthermore, the determination unit 104 is configured to start displaying information on the display device 30 when the contact sensor 23 detects contact with the handle on the outside of the door while the door is closed and the lock is unlocked. However, the determination unit 104 may also instruct the display device 30 to stop displaying information after a predetermined time (enough time for the person who was out to return home) has elapsed since instructing the display to start. This prevents the display on the display device 30 from continuing indefinitely.

[0029] The display control unit 105 controls the display of the display device 30 (for example, turning it on or off) according to the instructions of the determination unit 104.

[0030] <Method> Figure 3 is a sequence diagram of the processing of the door open status display system according to the first embodiment of the present invention.

[0031] In step 11 (S11), the control device 10 (key sensor information acquisition unit 102) acquires information detected by the key sensor 22 that the door lock is in an unlocked state.

[0032] In step 12 (S12), the control device 10 (door sensor information acquisition unit 101) acquires information that the door sensor 21 has detected that the door is open.

[0040] In step 24 (S24), the control device 10 (key sensor information acquisition unit 102) acquires information detected by the key sensor 22 that the door lock is in a locked state. At this time, the control device 10 (determination unit 104) instructs the display device 30 (display control unit 105) to end the display.

[0041] Figure 5 is a sequence diagram of the processing of the door open status display system according to the third embodiment of the present invention.

[0042] In step 31 (S31), the control device 10 (key sensor information acquisition unit 102) acquires information detected by the key sensor 22 that the door lock is in an unlocked state.

[0043] In step 32 (S32), the control device 10 (door sensor information acquisition unit 101) acquires information that the door sensor 21 has detected that the door is closed.

[0044] In step 33 (S33), the control device 10 (contact sensor information acquisition unit 103) acquires information detected by the contact sensor 23 that contact has been made with the handle on the outside side of the door. At this time, the control device 10 (determination unit 104) does not instruct the display device 30 (display control unit 105) to start displaying.

[0045] In step 34 (S34), assume that a predetermined time has elapsed (sufficient time from when the person who was out releases their hand from the handle until the door closes).

[0046] In step 35 (S35), if the predetermined time in S34 has elapsed, the control device 10 (determination unit 104) instructs the display device 30 (display control unit 105) to start displaying.

[0047] Figure 6 is a sequence diagram of the processing of the door open status display system according to the fourth embodiment of the present invention.

[0048] In step 41 (S41), the control device 10 (key sensor information acquisition unit 102) acquires information detected by the key sensor 22 that the door lock is in an unlocked state.

[0049] In step 42 (S42), the control device 10 (door sensor information acquisition unit 101) acquires information that the door sensor 21 has detected that the door is closed.

[0050] In step 43 (S43), the control device 10 (contact sensor information acquisition unit 103) acquires information detected by the contact sensor 23 that contact has been made with the handle on the outside side of the door. At this time, the control device 10 (determination unit 104) instructs the display device 30 (display control unit 105) to start displaying the information.

[0051] In step 44 (S44), assume that a predetermined amount of time has elapsed (enough time for the person who was out to return home).

[0052] In step 45 (S45), when the predetermined time in S44 has elapsed, the control device 10 (decision unit 104) instructs the display device 30 (display control unit 105) to end the display.

[0053] <Effects> Thus, in one embodiment of the present invention, it is possible to know before entering a home or office that an unlocked door has been opened (i.e., that there is a possibility of a burglary while the home was out). Therefore, it is possible to avoid dangers such as encountering a burglar and to take necessary countermeasures.
