[0003] [Patent Document 1] JP 2019-141565 A Summary of the Invention [Problem to be solved by the invention]

[0004] For example, it is conceivable to provide a means for unlocking a locked stall door from outside the stall. This allows the toilet manager to unlock the stall door from outside when an abnormality is detected and the stall door is automatically locked, and manage the stall, such as cleaning the inside of the stall. On the other hand, it is conceivable that the user of the stall may lock the door from inside the stall. There is a possibility that the manager may unlock the stall door from outside while the user is using the stall.

[0005] The present invention has been made based on the recognition of such problems, and aims to provide a door lock management system and a door lock management program that can prevent the manager from unlocking the door of a toilet cubicle when the toilet cubicle is in use. [Means for solving the problem]

[0006] A first invention is a door lock management system comprising a locking / unlocking device including a locking / unlocking unit for locking and unlocking the door of a toilet cubicle in which a toilet device is installed, and a control unit for controlling the locking / unlocking unit, wherein the control unit controls the locking / unlocking unit to lock the door when an abnormality inside the toilet cubicle is detected by an abnormality detection unit, and controls the locking / unlocking unit so as not to unlock the door by an unlocking operation from outside the toilet cubicle when a usage detection unit for detecting the usage status of the toilet cubicle detects that the toilet cubicle is in use.

[0007] This door lock management system can prevent the manager from unlocking the door of a toilet cubicle when the toilet cubicle is in use.

[0008] A second invention is a door lock management system according to the first invention, characterized in that the usage detection unit determines that the toilet cubicle is in use when it detects that a user has locked the door from inside the toilet cubicle.

[0009] According to this door lock management system, it is possible to determine whether a toilet cubicle is in use based on whether the toilet cubicle is locked from the inside, which can further prevent the door of the toilet cubicle from being accidentally unlocked while it is in use.

[0010] A third invention is a door lock management system characterized in that, in the first invention, the usage detection unit determines that the toilet cubicle is in use when it detects that the toilet device is in use.

[0011] According to this door lock management system, it is possible to determine whether a toilet cubicle is in use based on the usage status of the toilet device. This makes it possible to prevent the door of a toilet cubicle from being accidentally unlocked while it is in use, with a simple configuration.

[0012] A fourth invention is a door lock management system characterized in that, in the first invention, the usage detection unit determines that the toilet cubicle is in use when it detects a person inside the toilet cubicle.

[0013] This door lock management system can determine whether a toilet cubicle is in use based on the presence or absence of a person in the cubicle, which makes it possible to prevent the door of an in-use toilet cubicle from being accidentally unlocked with a simple configuration.

[0014] A fifth invention is a door lock management system, characterized in that in any one of the second to fourth inventions, the system further includes a display device provided outside the toilet cubicle, and the display device displays that the toilet cubicle is in use when the usage status detection unit determines that the toilet cubicle is in use.

[0015] With this door lock management system, the display device shows that the toilet cubicle is in use, which discourages the manager from trying to unlock it. This prevents users from feeling anxious that the door may be unlocked.

[0016] A sixth invention is a door lock management system, characterized in that in the first invention, the system further includes a communication device that can communicate with a terminal device portable by an administrator when the terminal device approaches, and the control unit controls the locking / unlocking unit to unlock the door when the terminal device and the communication device communicate with each other when the usage detection unit does not detect that the toilet cubicle is in use.

[0017] According to this door lock management system, the door can be unlocked without using a key that touches the locking / unlocking device to operate the locking / unlocking part. This can reduce, for example, the cost of managing keys. It can also reduce the time cost of returning to get the key when the key is forgotten.

[0018] A seventh invention is a door lock management system according to the first invention, further comprising the toilet device, the door, the abnormality detection unit, and the usage status detection unit.

[0019] This door lock management system can prevent the manager from unlocking the door of a toilet cubicle when the toilet cubicle is in use.

[0020] An eighth invention is a door lock management program characterized in that the control unit of a locking / unlocking device including a locking / unlocking unit that locks and unlocks the door of a toilet cubicle in which a toilet device is installed, and a control unit that controls the locking / unlocking unit, executes an operation of controlling the locking / unlocking unit to lock the door when an abnormality inside the toilet cubicle is detected by an abnormality detection unit, and controlling the locking / unlocking unit not to unlock the door by an unlocking operation from outside the toilet cubicle when a usage status detection unit that detects the usage status of the toilet cubicle detects that the toilet cubicle is in use.

[0021] This door lock management program can prevent the manager from unlocking the door of a toilet cubicle when the toilet cubicle is in use. Effect of the Invention

[0022] According to an aspect of the present invention, a door lock management system and a door lock management program are provided that can prevent an administrator from unlocking the door of a toilet cubicle when the toilet cubicle is in use. [Brief description of the drawings]

[0024] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, the same components are designated by the same reference numerals and detailed description thereof will be omitted as appropriate. FIG. 1 is a schematic diagram illustrating a toilet room in which a door lock management system according to an embodiment is provided. As shown in FIG. 1, a toilet room TR is provided with one or more toilet cubicles TB (toilet booths). A toilet device 11 is provided inside each toilet cubicle TB. The toilet device 11 is, for example, a Western-style or Japanese-style toilet device. Each toilet cubicle TB has a door 14 for allowing a user of the toilet cubicle TB to enter and exit the toilet cubicle TB. For example, when the toilet cubicle TB is in use (when there is a user inside), the door 14 is closed. When the toilet cubicle TB is not in use, the door 14 may be in an open or closed state.

[0025] The toilet room TR may also be provided with a washbasin 15 and a urinal device 16. The washbasin 15 is provided with a faucet device 15a (e.g., an automatic faucet device) that discharges water, a bowl portion 15b that receives water from the faucet device 15a, and the like.

[0026] In a facility where the door lock management system 100 according to the embodiment is installed, for example, a plurality of toilet rooms TR are provided. Each toilet room TR is managed, for example, by a manager of the facility in which the toilet room TR is provided. The manager cleans and maintains the toilet room TR. For example, the maintenance includes checking whether a malfunction has occurred, checking the details of the malfunction, and taking measures to resolve the malfunction or prevent the malfunction from spreading as necessary.

[0027] The door lock management system 100 is a system that detects an abnormality inside a toilet cubicle TB, and appropriately locks and unlocks the door 14 of the toilet cubicle TB in which an abnormality has been detected. For example, the door lock management system 100 according to the embodiment may have a management device 30. For example, one management device 30 is communicatively connected to devices (locking / unlocking devices and detection units described below) provided in each toilet cubicle TB of each toilet room TR, via wired, wireless, or a combination thereof. In this way, the management device 30 manages the locking of multiple toilet cubicles TB. However, in the embodiment, the number of toilet cubicles TB is arbitrary and may be one.

[0028] Specifically, a computer device such as a server or a personal computer can be used as the management device 30. The management device 30 may be installed outside the restroom TR, for example, in a central management room of the facility in which the door lock management system 100 is installed. However, the location of the management device 30 is arbitrary, and it may be installed inside the restroom TR.

[0029] FIG. 2 is a schematic diagram illustrating a toilet cubicle TB in which the door lock management system according to the embodiment is provided. 2, the door lock management system 100 according to the embodiment includes a locking / unlocking device 20. The locking / unlocking device 20 is installed on the door 14 of the toilet cubicle TB, and locks and unlocks the door 14. The door lock management system 100 may also include a display device 40 that displays the locking state of the door 14, and an input device 50 through which an administrator inputs information for releasing the locking performed by the locking / unlocking device 20.

[0030] The toilet device 11 includes, for example, a toilet bowl (toilet bowl body) that receives waste and discharges it into a drain pipe. The toilet device 11 may also include a water tank and a pump that supply water to the toilet bowl body. The toilet device 11 may also include a toilet seat device that includes a toilet seat and a toilet lid on which a user of the toilet device 11 sits. The toilet seat device may have various functional parts as necessary, such as a private parts washing function that discharges washing water onto the private parts of a seated user, a warm air function that dries the private parts, a heated toilet seat function that warms the toilet seat, a deodorizing function that deodorizes the inside of the toilet bowl or the toilet cubicle TB, and a flushing function that flushes the toilet bowl. A remote control 12 for operating each functional part of the toilet device (toilet seat device) may also be provided in the toilet cubicle TB. For example, an operation command is transmitted to the toilet device by a user operating an operation part such as a button on the remote control 12. The toilet device (toilet seat device) operates each functional part according to the received operation command.

[0031] The toilet device 11 may be provided with a seating sensor and a human body detection sensor. The seating sensor detects when a user sits on and leaves the toilet seat. The seating sensor may be, for example, a distance measuring sensor (infrared light projecting sensor), an ultrasonic sensor, a tact switch, a capacitance switch (touch sensor), or a distortion sensor. The human body detection sensor detects the presence and movement of a user in the toilet cubicle TB. The human body detection sensor may be, for example, a pyroelectric sensor, a microwave sensor, an ultrasonic sensor, or a distance measuring sensor (infrared light projecting sensor).

[0032] FIG. 3 is a schematic block diagram illustrating a door lock management system according to the embodiment. The locking / unlocking device 20 includes a locking / unlocking unit 21, a control unit 22, and a communication unit 23. The locking / unlocking unit 21 is attached to the door 14 of the toilet private room TB, and locks and unlocks the door 14.

[0033] For example, an electric lock (electronic lock) can be used for the locking / unlocking unit 21. As an example, the locking / unlocking unit 21 is a motor-type electric lock. For example, the locking / unlocking unit 21 has an engagement portion having a shape such as a latch or a hook. The engagement portion engages with a metal fitting or the like provided on a panel (such as a door frame) adjacent to the door 14. The locking / unlocking unit 21 locks the door 14 by maintaining the engagement portion in an engaged state. That is, the locking / unlocking unit 21 holds the door 14 in a closed state. The locking / unlocking unit 21 unlocks the door 14 by releasing the engagement of the engagement portion (or making it releasable). That is, the locking / unlocking unit 21 does not hold the door 14 in a closed state, but makes the door 14 in a state in which it can be opened. In addition, the locking / unlocking unit 21 has a position control mechanism that controls the position of the engagement portion. The position control mechanism includes an actuator including, for example, a motor, and moves the engagement portion. The position control mechanism, for example, moves the engaging portion to engage the metal fittings or the like with the engaging portion, thereby locking the door 14. The position control mechanism, for example, restricts the movement of the engaging portion to a position where the engagement is released, thereby locking the door 14. Also, the position control mechanism, for example, moves the engaging portion to release the engagement of the engaging portion with the metal fittings or the like, thereby unlocking the door 14. Alternatively, the position control mechanism unlocks the door 14 by not restricting the movement of the engaging portion to a disengagement position.

[0034] The control unit 22 is communicatively connected to the locking / unlocking unit 21, and controls the operation of the locking / unlocking unit 21. The locking / unlocking unit 21 locks or unlocks the door 14 in response to a signal from the control unit 22. For example, the control unit 22 transmits a signal to the position control mechanism to execute locking or unlocking. In response to receiving the signal, the position control mechanism controls the engagement unit, causing the locking / unlocking unit 21 to lock or unlock the door 14. The control unit 22 is a control circuit that controls the locking / unlocking unit 21, and may include a computer such as a microcomputer.

[0035] The locking / unlocking unit 21 may be capable of locking and unlocking the door 14 not only under the control of the control unit 22, but also in response to an operation from inside the toilet cubicle TB by a user of the toilet cubicle TB. For example, the door 14 may be locked and unlocked by the user manually applying force to an engagement part of the locking / unlocking unit 21 to move the engagement part. Alternatively, an inside operation part (e.g. a switch such as a push button) for the user to instruct locking and unlocking may be provided inside the toilet cubicle TB. When the user operates the inside operation part, a signal is transmitted to the position control mechanism. As a result, the position control mechanism may control the position of the engagement part, causing the locking / unlocking unit 21 to lock and unlock the door 14.

[0036] The embodiment is not limited to the above, and the locking / unlocking unit 21 may be configured to be able to switch between a state in which the door 14 is kept closed and a state in which the door 14 can be opened, based on a signal from the control unit 22.

[0037] The control unit 22 is connected to the communication unit 23 so as to be able to communicate with each other. The control unit 22 transmits and receives signals to and from other devices via the communication unit 23. The communication unit 23 is able to communicate with the communication unit 32 of the management device 30. That is, the control unit 22 is able to communicate with the determination unit 31 via the communication unit 23 and the communication unit 32. The communication unit 23 is also able to communicate with the detection unit 62a. That is, the control unit 22 is able to communicate with the detection unit 62a via the communication unit 23. However, the communication between the control unit 22 and the detection unit 62a does not have to be via the communication unit 23. The communication unit 23 may also be able to communicate with the communication unit 17 provided in the toilet device 11. For example, the control unit 22 may be able to communicate with the detection unit 61a provided in the toilet device 11 via the communication unit 23 and the communication unit 17. The communication unit 23 may also be able to communicate with the communication unit 52 of the input device 50. For example, the control unit 22 may be able to communicate with an input unit 51 of the input device 50 via the communication unit 23 and the communication unit 52.

[0038] The management device 30 has a determination unit 31 and a communication unit 32. A computer device such as a server or a personal computer can be used as the determination unit 31. The determination unit 31 transmits and receives signals to and from other devices via the communication unit 32. The communication unit 32 can communicate with the communication unit 17 provided in the toilet device 11. That is, the determination unit 31 can communicate with the detection unit 61a provided in the toilet device 11 via the communication unit 32 and the communication unit 17. The communication unit 32 may be capable of communicating with the communication unit 42 of the display device 40. The determination unit 31 may be capable of communicating with the display unit 41 of the display device 40 via the communication unit 32 and the communication unit 42. The communication unit 32 may be capable of communicating with the communication unit 52 of the input device 50. The determination unit 31 may be capable of communicating with the input unit 51 of the input device 50 via the communication unit 32 and the communication unit 52.

[0039] The door lock management system 100 has, for example, a usage status detection unit 62 that detects the usage status of the toilet cubicle TB. The usage status detection unit 62 is composed of, for example, a detection unit 62a and a determination unit 62b (part of the determination unit 31). The detection unit 62a acquires information used to determine the usage status of the toilet cubicle. In this example, the detection unit 62a is provided for the locking / unlocking device 20 so as to detect the state of the locking / unlocking device 20. The detection unit 62a is communicatively connected to the determination unit 62b via the communication unit 23 and the communication unit 32. As a result, the detection result of the detection unit 62a is transmitted to the determination unit 62b. The determination unit 62b determines the usage status of the toilet cubicle TB based on the detection result of the detection unit 62a. The usage status detection unit 62 determines whether the toilet cubicle TB is in use, i.e., whether a user is present in the toilet cubicle TB. For example, when the door 14 is locked from the inside of the toilet cubicle TB, it can be determined that a user is present in the toilet cubicle TB.

[0040] As an example, the detection unit 62a is a position sensor capable of detecting the position of an engagement portion (such as a latch) of the locking / unlocking unit 21. The detection unit 62a acquires information according to, for example, whether the engagement portion is in the locked position. Based on the detection result of the detection unit 62a, it detects whether the door 14 is being locked by the locking / unlocking unit 21. For example, the detection unit 62a (position sensor) can be any sensor capable of detecting the locked state, such as an optical sensor such as a distance measuring sensor (infrared light projector sensor), a magnetic sensor, or a tact switch.

[0041] The door lock management system 100 has, for example, an abnormality detection unit 61 that detects an abnormality in the toilet cubicle TB. The abnormality detection unit 61 is composed of, for example, a detection unit 61a and a determination unit 61b (part of the determination unit 31). In this example, the detection unit 61a is provided for the toilet device 11 so as to detect an abnormality (such as clogging) in the toilet device 11. The detection unit 61a is communicatively connected to the determination unit 61b via the communication unit 17 and the communication unit 32. As a result, the detection result of the detection unit 61a is transmitted to the determination unit 61b. The determination unit 61b determines whether an abnormality has occurred in the toilet cubicle TB based on the detection result of the detection unit 61a.

[0042] As an example, the detection unit 61a is a water level sensor that detects the water level inside the toilet bowl of the toilet device 11. If the water level inside the toilet bowl acquired by the water level sensor is equal to or higher than a predetermined value, it is determined that an abnormality has occurred. In this case, for example, there is a possibility that the toilet bowl or the drain pipe is clogged. The water level sensor may be of any suitable type, such as a capacitance type or a float type.

[0043] The display device 40 has, for example, a display unit 41 and a communication unit 42. The display device 40 (display unit 41) is provided outside the toilet cubicle TB, and displays whether the toilet cubicle TB is in use. The display unit 41 may be a display device such as a liquid crystal display or an organic EL display. The display unit 41 may also be a light source such as an LED, and may display the use status of the toilet cubicle TB by, for example, lighting up or blinking.

[0044] The input device 50 has an input section 51 and a communication section 52. The input section 51 is provided outside the toilet cubicle TB. The input device 50 (input section 51) is a device into which a manager or the like inputs information for unlocking the locked door 14 from outside the toilet cubicle TB. When the manager inputs predetermined information into the input section 51, a signal is transmitted to the control section 22 of the locking / unlocking device 20 via the communication sections 52 and 23. In response to the signal, the control section 22 controls the locking / unlocking section 21 to unlock the door 14. However, when a user is using the toilet cubicle TB, the control section 22 does not unlock the door 14.

[0045] The input unit 51 is, for example, an input switch such as a numeric keypad. Alternatively, the input unit 51 may be a communication device that reads information on a terminal such as a card key carried by the administrator. The administrator can unlock the door 14 by having the input unit 51 read (input) the information on the terminal by holding the card key over the terminal, for example.

[0046] The communication may be performed by any suitable method such as wired, wireless, or a combination thereof. For example, the communication may be performed via the Internet or a LAN (Local Area Network). The communication unit is, for example, a communication module compatible with wired or wireless communication.

[0047] An example of the operation of the door lock management system will be described with reference to FIGS. Fig. 4 is a flow chart for explaining the operation of the door lock management system according to the embodiment, which shows the operation from when the user enters the toilet private room TB to when the door 14 is locked. A user enters the toilet cubicle TB (step S101). The user operates the locking / unlocking unit 21 from inside the toilet cubicle TB to lock the door 14.

[0048] The detection unit 62a installed in the locking / unlocking device 20 detects whether the door 14 is locked (step S102). The communication unit 23 notifies the management device 30 of the detection result of the detection unit 62a (step S103). The determination unit 61b determines the usage status of the toilet cubicle based on the detection result of the detection unit 62a.

[0049] Fig. 5 is a flow chart for explaining the operation of the door lock management system according to the embodiment. Fig. 5 shows the operation from when an abnormality occurs in the toilet private room TB until the door is locked. The detection unit 61a installed in the toilet device 11 acquires information used to detect an abnormality (step S104). The communication unit 17 notifies the management device 30 of the detection result of the detection unit 61a. The determination unit 61b determines whether or not an abnormality has occurred based on the detection result of the detection unit 61a.

[0050] If an abnormality has occurred, the communication unit 32 of the management device 30 transmits a command to the locking / unlocking device 20 to lock the door 14 (step S105). The control unit 22 receives the locking command and controls the locking / unlocking unit 21 to lock the door 14 (step S106). Note that, for example, the determination unit 61b may be provided in the toilet device 11, and the locking command may be transmitted directly from the toilet device 11 to the locking / unlocking device 20 without going through the management device 30.

[0051] In this way, when an abnormality in the toilet cubicle TB is detected by the abnormality detection unit 61, the control unit 22 controls the locking / unlocking unit 21 to lock the door 14. When an abnormality is detected, the control unit 22 locks the door 14 at least when there is no user in the toilet cubicle TB. When an abnormality is detected, the control unit 22 may not lock the door 14 when there is a user in the toilet cubicle TB, and may lock the door 14 after the user leaves the toilet cubicle TB. Alternatively, the control unit 22 may lock the door 14 when there is a user in the toilet cubicle TB. From inside the toilet cubicle TB, the user can lock or unlock the door 14 at any timing, regardless of the detection result of the abnormality.

[0052] If necessary, an opening and closing device may be provided to electrically open and close the door 14. If the door 14 is open when an abnormality is detected, the control unit 22 may appropriately control the opening and closing device to close and then lock the door 14. The opening and closing device may have any configuration, and may include, for example, a drive unit including a motor or the like, and a transmission unit such as a belt that transmits the driving force of the drive unit to the door 14.

[0053] Fig. 6 is a flow chart for explaining the operation of the door lock management system according to the embodiment, which shows the operation when a manager who performs cleaning or the like unlocks the locked door 14. For example, the locking / unlocking unit 21 locks the door 14 by an operation by a user from inside the toilet cubicle TB. Alternatively, an abnormality is detected inside the toilet cubicle TB, and the locking / unlocking unit 21 locks the door 14 by control of the control unit 22.

[0054] The manager inputs predetermined information into the input unit 51 of the input device 50 (step S107). The communication unit 52 of the input device 50 transmits a signal corresponding to the input into the input unit 51 to the locking / unlocking device 20 (step S108). In this manner, an unlocking command to unlock the door 14 of the locked toilet cubicle TB is transmitted to the control unit 22 via the input device 50.

[0055] The communication unit 23 of the locking / unlocking device 20 that has received the unlock command transmits the unlock command to the management device 30 (step S109). For example, the unlock command is transmitted from the control unit 22 to a computer device including the determination unit 31 via the communication unit 23 and the communication unit 32. Note that the unlock command may be transmitted from the input device 50 directly to the management device 30 in response to an input to the input unit 51, without passing through the locking / unlocking device 20.

[0056] When the management device 30 receives the unlock command, it determines whether or not the door can be unlocked, and transmits the determination result to the locking / unlocking device 20 (step S110). For example, the management device 30 transmits the determination result of whether or not the door can be unlocked to the control unit 22 via the communication unit 32 and the communication unit 23.

[0057] Specifically, the management device 30 (determination unit 31) determines whether or not to unlock the toilet cubicle TB based on the detection result of the usage status detection unit 62. The management device 30 (determination unit 31) determines that the toilet cubicle TB cannot be unlocked when the usage status detection unit 62 determines that a user is present in the toilet cubicle TB, and determines that the toilet cubicle TB can be unlocked when the usage status detection unit 62 determines that a user is not present in the toilet cubicle TB.

[0058] In the locking / unlocking device 20, when the determination result of whether or not the door can be unlocked sent from the management device 30 is unlockable (step S111: YES), the control unit 22 controls the locking / unlocking unit 21 to unlock the door 14 (step S112). On the other hand, when the determination result of whether or not the door can be unlocked sent from the management device 30 is not unlockable (step S111: NO), the control unit 22 controls the locking / unlocking unit 21 not to unlock the door 14 (step S113).

[0059] In this way, when the usage status detection unit 62 does not detect that the toilet cubicle TB is in use, the control unit 22 controls the locking / unlocking unit 21 so that the door 14 can be unlocked by a predetermined unlocking operation from outside the toilet cubicle TB. In the example of Fig. 6, the unlocking operation from outside is an operation of inputting information into the input device 50. For example, when the toilet cubicle TB is not in use and an input operation is performed into the input device 50, the control unit 22 transmits a signal to the locking / unlocking unit 21 to execute an unlocking operation.

[0060] On the other hand, when the use state detection unit 62 detects that the toilet cubicle TB is in use, the control unit 22 controls the locking / unlocking unit 21 so as not to unlock the door 14 by an unlocking operation from outside the toilet cubicle. That is, for example, even if an unlocking operation is performed from outside the toilet cubicle when the toilet cubicle TB is in use, the control unit 22 performs control not to cause the locking / unlocking unit 21 to unlock the door 14 (for example, does not execute control to cause the locking / unlocking unit 21 to unlock the door 14). That is, in the example of FIG. 6, even if an input operation is performed on the input device 50 while the toilet cubicle TB is in use, the control unit 22 does not transmit a signal to cause the locking / unlocking unit 21 to execute an unlocking operation. According to the embodiment, it is possible to prevent the manager from unlocking the door of the toilet cubicle when the toilet cubicle TB is in use.

[0061] In the above example, the input device 50 receives an input to send an unlock command, but the input device 50 installed in a toilet cubicle TB in which no abnormality is detected may be controlled not to accept input. For example, a signal indicating that the abnormality detection unit 61 has not detected an abnormality is sent to the input device 50 from the management device 30 or the toilet device 11. In response to the signal, the input device 50 may transition to a mode in which it does not accept input. Alternatively, the power supply of the input device 50 may be turned off. In this way, by the input device 50 not accepting an input, it is possible to inhibit the unlocking of a toilet cubicle TB in use.

[0062] The unlocking operation from outside is not limited to an input operation to the input device 50. For example, the unlocking operation from outside may be an unlocking command sent to the control unit 22 from an administrator terminal (e.g., a smartphone or tablet terminal) carried by an administrator or the management device 30. For example, when the toilet cubicle TB is not in use and an unlocking command is received from the administrator terminal or the management device 30, the control unit 22 sends a signal to the locking / unlocking unit 21 to execute an unlocking operation. On the other hand, even if the control unit 22 receives an unlocking command from the administrator terminal or the management device 30 while the toilet cubicle TB is in use, for example, the control unit 22 does not send a signal to the locking / unlocking unit 21 to execute an unlocking operation.

[0063] Alternatively, the unlocking operation from the outside may be an operation in which the manager manually applies force to the locking / unlocking device 20 from the outside, as in the case of a cylinder lock. In other words, the unlocking operation from the outside may be an operation in which the manager manually moves the engagement part (such as a latch) of the locking / unlocking part 21. For example, when the toilet cubicle TB is not in use, the control unit 22 does not restrict the movement of the engagement part to the disengagement position by the position control mechanism. This allows the manager to manually move the locking / unlocking part 21 to unlock the door 14. On the other hand, for example, when the toilet cubicle TB is in use, the control unit 22 restricts the movement of the engagement part to the disengagement position by the position control mechanism. This prevents the locking / unlocking part 21 from being manually moved by the manager, and the door 14 is not unlocked.

[0064] In addition, in preparation for emergencies, for example, in addition to the above-mentioned specified unlocking operation, an operation (such as sending a forced unlocking command from the management device 30 to the locking / unlocking device 20) may be set that allows an administrator to unlock the door 14 from outside even when the toilet cubicle TB is in use.

[0065] In the above example, the usage status detection unit 62 determines that the toilet cubicle TB is in use when it detects that the user has locked the door 14 from inside the toilet cubicle TB. In this way, according to the embodiment, it is possible to determine that the toilet cubicle TB is in use based on locking from inside the toilet cubicle TB. This makes it possible to further prevent the door of the toilet cubicle TB from being erroneously unlocked while it is in use.

[0066] Specifically, for example, the determination unit 62b obtains a detection result of whether the door 14 is locked from the detection unit 62a. Also, the determination unit 62b obtains information as to whether an abnormality has been detected and a locking command has been sent to the control unit 22 via the communication unit 23, for example, as described with reference to FIG. 5. When a locking command has been sent to the control unit 22 via the communication unit 23 and the door 14 is locked, the determination unit 62b determines that the toilet cubicle TB is not in use, since it is considered that an abnormality has occurred and automatic locking has been performed. On the other hand, when a locking command has not been sent to the control unit 22 via the communication unit 23 and the door 14 is locked, the determination unit 62b determines that the toilet cubicle TB is in use, since it is considered that a user has locked it from the inside.

[0067] The use state detection unit 62 and the method for determining whether the toilet cubicle TB is in use are not limited to the above. Another example of the use state detection unit 62 will be described with reference to Figs.

[0068] FIG. 7 is a schematic block diagram illustrating another door lock management system according to the embodiment. In FIG. 7, the detection unit 62a of the use state detection unit 62 is provided in the toilet apparatus 11, not in the locking / unlocking device 20. Specifically, a seating sensor provided in the toilet apparatus 11 can be used as the detection unit 62a. The detection result of the detection unit 62a is transmitted to the determination unit 62b via the communication unit 17 and the communication unit 32. The determination unit 62b determines the use state of the toilet cubicle TB based on the detection result of the detection unit 62a. For example, when a person is seated on the toilet apparatus 11, the determination unit 62b determines that the toilet apparatus 11 is in use and the toilet cubicle TB is in use. On the other hand, when a person is not seated on the toilet apparatus 11, the determination unit 62b determines that the toilet apparatus 11 is not in use and the toilet cubicle TB is not in use.

[0069] In this way, the usage status detection unit 62 may determine that the toilet cubicle TB is in use when it detects that the toilet apparatus 11 is in use. According to the embodiment, it is possible to determine that the toilet cubicle TB is in use based on the usage status of the toilet apparatus 11. This makes it possible, with a simple configuration, to further prevent the door 14 of the toilet cubicle TB in use from being erroneously unlocked.

[0070] The detection unit 62a is not limited to a seating sensor, and may be a human body detection sensor provided in the toilet device 11. The determination unit 62b determines that the toilet cubicle TB is in use when a user in the toilet cubicle TB is detected by the human body detection sensor. The determination unit 62b determines that the toilet cubicle TB is not in use when a user in the toilet cubicle TB is not detected by the human body detection sensor.

[0071] FIG. 8 is a schematic block diagram illustrating another door lock management system according to the embodiment. In FIG. 8, the detection unit 62a of the usage detection unit 62 is provided as a device (detection device 60) separate from the locking / unlocking device 20 and the toilet device 11. The detection unit 62a is a human body detection sensor included in the detection device 60. The detection unit 62a is configured to be able to communicate with the determination unit 62b. The detection device 60 may be located at any position where the detection unit 62a can detect a user in the toilet cubicle TB. The detection unit 62a can be placed at any position that satisfies its function. For example, the detection unit 62a (human body detection sensor) may be incorporated in the locking / unlocking device 20 as shown by the dashed line in FIG. 8.

[0072] In this way, the usage status detection unit 62 may determine that the toilet cubicle TB is in use when it detects a person in the toilet cubicle TB. According to the embodiment, it is possible to determine that the toilet cubicle TB is in use based on the presence or absence of a person in the toilet cubicle TB. This makes it possible, with a simple configuration, to further prevent the door 14 of the toilet cubicle TB from being erroneously unlocked while in use.

[0073] In the above example, the abnormality in the toilet cubicle TB is a clog in the toilet device 11, and the detection unit 61a that detects the abnormality is a water level sensor provided in the toilet device 11. However, the abnormality is not limited to a clog in the toilet device 11. The abnormality detection unit 61 and the method of determining whether or not an abnormality has occurred are not limited to those described above.

[0074] For example, the detection unit 61a may be a water level sensor provided in the tank of the toilet device 11. If the water level acquired by the water level sensor is equal to or higher than a predetermined value, it may be determined that an abnormality such as a clog or operational malfunction has occurred. For example, a temperature sensor may be provided in the toilet seat device or the water heater as the detection unit 61a. For example, if the temperature acquired by the temperature sensor is equal to or higher than a predetermined value or differs from a change expected in advance, it is determined that an abnormality has occurred in the facility equipment. For example, an input device such as the remote control 12, or a human body detection sensor or seating sensor of the toilet device 11 may function as the detection unit 61a. For example, when an input to the remote control 12 satisfies a predetermined condition (for example, when a predetermined button is operated a predetermined number of times or more in succession), it is determined that an abnormality has occurred in the remote control 12 or the toilet device 11. For example, when the human body detection sensor or seating sensor does not detect a user, and a predetermined input such as an input instructing the execution of a private parts washing function is received in the remote control, it is determined that a malfunction has occurred in the human body detection sensor, seating sensor, remote control 12, or toilet device 11. For example, the detection unit 61a may be a sensor that detects the position or weight of the toilet paper in the paper roll. The remaining amount of toilet paper may be detected from the detection result of the sensor, and if the remaining amount of toilet paper falls below a predetermined value, it may be determined that an abnormality has occurred.

[0075] The target of abnormality detection may be any equipment provided in the toilet cubicle TB. For example, the target of abnormality detection may be a water supply pipe or drain pipe connected to the toilet device 11, lighting in the toilet cubicle TB, a ventilation fan, a floor, a faucet device, a water heater, a hand dryer provided in the toilet cubicle TB, and other equipment and sensors in the toilet cubicle TB.

[0076] The embodiment is not limited to the above, and the abnormality may be related to the state inside the toilet cubicle TB (e.g., a malfunction). The detection unit 61a may appropriately use various information acquisition means, such as an imaging device, an optical sensor, a distance measurement sensor, a microphone, a weight scale, a current sensor, and a voltage sensor. The detection unit 61a can be disposed in any position that satisfies its function. For example, the detection unit 61a may also function as the detection unit 62a. The configuration in which the detection unit 61a and the detection unit 62a are provided may include a configuration in which the detection unit 61a also functions as the detection unit 62a.

[0077] When the usage status detection unit 62 determines that the toilet cubicle TB is in use, the display device 40 displays that the toilet cubicle TB is in use. Because the display device 40 displays that the toilet cubicle TB is in use, the action of a manager (e.g., a cleaner) attempting to unlock the door can be suppressed. This can suppress anxiety of a user who is using the toilet cubicle TB that the door 14 may be unlocked.

[0078] The input device 50 may be a communication device that can communicate with the terminal device 70 when the terminal device 70, which is portable by the administrator, approaches the input device 50. For example, the terminal device 70 and the input device 50 communicate with each other according to the Near Field Communication (NFC) standard at a frequency such as 13.56 MHz. The terminal device 70 may include an IC chip compatible with NFC. Specifically, the terminal device 70 may be a card key such as an IC card (administrator identification mechanism) or a mobile information terminal such as a smartphone. RFID (radio frequency identifier) ​​may be used for communication. Predetermined information such as the administrator's identification information is written in the terminal device 70 (IC chip). When the administrator brings the terminal device 70 close to the input device 50, the input device 50 reads the information written in the terminal device 70. For example, when the terminal device 70 approaches the input device 50 within a distance of about 10 cm, communication is possible. When communication is established between the input device 50 and the terminal device 70, an unlock command is transmitted from the input device 50 to the locking / unlocking device 20, as described with reference to FIG.

[0079] When the use state detection unit 62 does not determine that the toilet cubicle is in use while the door 14 is locked, the control unit 22 of the locking / unlocking device 20 controls the locking / unlocking unit 21 to unlock the door 14 if the terminal device 70 and the input device 50 (communication device) communicate with each other. In this way, the manager can unlock the door without touching it.

[0080] On the other hand, a method using a physical key that directly contacts the locking / unlocking device to operate the locking / unlocking part, such as a key inserted into a keyhole, may be considered. However, in this case, there is a risk that a manager such as a cleaner will forget the key and will have to go back to get the forgotten key, resulting in a loss of time. In addition, for example, there is a risk that the manager will lose the key and will need to reissue the key. In this way, there is a possibility that the efficiency of the entire cleaning / management work will decrease. In contrast, in this example, the door 14 can be unlocked without using a key that directly contacts the locking / unlocking device 20. This can reduce, for example, the cost of managing the keys. In addition, it is possible to reduce the time cost of going back to get the key when the key is forgotten.

[0081] Note that the communication with the terminal device 70 is not limited to communication according to the NFC standard. For example, the input device may be a communication device such as a beacon device. The communication device and the terminal device 70 may communicate with each other according to the BLE (Bluetooth Low Energy) standard using a Bluetooth (registered trademark) signal.

[0082] The functional blocks configured by the control circuit and the computer device, such as the control unit 22 and the management device (determination unit), are functionally conceptual and do not necessarily have to be physically configured as illustrated. A part or all of the multiple functional blocks may be aggregated as appropriate. Each functional block may be distributed to multiple elements communicably connected via a network. A part of each functional block may be moved to another block. The layout and configuration of the control circuit and the computer device are not limited to those illustrated, and any layout and configuration that can satisfy these functions may be used. Each component of the embodiment may be functionally or physically distributed or integrated as appropriate. For example, one computer device may serve as both the determination unit 61b and the determination unit 62b.

The door lock management program is, for example, installed in the control unit 22 (locking / unlocking device 20) and includes a program unit that causes the control unit 22 to execute each operation of the above-described control unit 22. The door lock management program is, for example, installed in the management device 30 (determination unit) and includes a program unit that causes the management device 30 to execute each operation of the above-described management device 30. However, a part or all of the operations of the door lock management system 100 according to the embodiment may be executed based on the operation of hardware that does not require a program.

[0084] The program according to the embodiment is not limited to the form of a program (provided in the computer) for making the computer execute the above-mentioned method, but may be in the form of a computer-readable recording medium.
