[0012] In the following embodiments and modifications, the same or equivalent components and members are denoted by the same reference numerals, and redundant explanations are omitted where appropriate. The dimensions of the members in each drawing are enlarged or reduced as appropriate for ease of understanding. Some members that are not important for explaining the embodiments are omitted from the drawings.

[0013] First embodiment An embodiment of an automatic door system will be described below with reference to Figures 1 to 4. The automatic door system is installed in a multi-function toilet.

[0014] As shown in Figure 1, the multi-function toilet 1 is a private room with one entrance / exit 2, and a toilet bowl 3 is installed in a spacious space to make it easy to use for people with disabilities and people with children. An automatic door device 5 that drives the opening and closing of a door 4 is installed at the entrance / exit 2. The door 4 is a sliding door that opens and closes the entrance / exit 2. The multi-function toilet 1 corresponds to a private room. The entrance / exit 2 corresponds to an opening.

[0015] An outer door operating unit 30 that operates the opening and closing of the door 4 is installed on the outer wall of the multi-function toilet 1. An inner door operating unit 40 that also operates the opening and closing of the door 4 is installed on the inner wall of the multi-function toilet 1. An object detection sensor 12 that detects people and objects passing outside the entrance / exit 2 is installed on the outside of the entrance / exit 2. The object detection sensor 12 detects people and objects that are present in a detection area A that is outside the entrance / exit 2 and is a predetermined range from the entrance / exit 2. An auxiliary sensor 13 that detects people standing inside the entrance / exit 2 is installed on the inner wall of the entrance / exit 2. An occupancy sensor 15 that detects users in the stall is installed on the ceiling. An emergency switch 16 is installed on the wall near the toilet 3. The emergency switch 16 is a switch that a user operates when they become unwell, etc. When operated, the emergency switch 16 outputs an emergency signal.

[0016] The outer door operation unit 30 and the inner door operation unit 40 have substantially the same configuration. As shown in FIG. 2, the outer door operation unit 30 and the inner door operation unit 40 are equipped with contact switches. The contact switches output open / close commands to open / close the door 4 by pressing a button switch. An outer opening switch 31 (inner opening switch 41) is provided near the top of the outer door operation unit 30 and the inner door operation unit 40. The outer opening switch 31 and the inner opening switch 41 have "OPEN, ←→, OPEN" written on their surfaces. The outer opening switch 31 and the inner opening switch 41 output an open command to the door 4 when the user presses the button switch. An outer closing switch 32 (inner closing switch 42) is provided near the bottom of the outer door operation unit 30 and the inner door operation unit 40. The outer closing switch 32 and the inner closing switch 42 have "CLOSED, →←, CLOSE" written on their surfaces. The outer closing switch 32 and the inner closing switch 42 output a close command to the door 4 when the user presses the button switch. The outer opening switch 31, the inner opening switch 41, the outer closing switch 32, and the inner closing switch 42 each have a built-in LED that lights up or flashes to guide the user's operation. An outer speaker 35 (an inner speaker 45) is provided between the outer opening switch 31 (the inner opening switch 41) and the outer closing switch 32 (the inner closing switch 42). The outer opening switch 31, the inner opening switch 41, the outer closing switch 32, and the inner closing switch 42 are not limited to button switches, and may be switches such as touch sensors. The outer door operation unit 30 and the inner door operation unit 40 of this embodiment are examples of operation receiving units. Hereinafter, the outer door operation unit 30 and the inner door operation unit 40 may be collectively referred to as door operation units.

[0017] The outer door operating unit 30 is equipped with a forced unlocking switch 36. The forced unlocking switch 36 is a cylinder lock that outputs a forced unlocking signal when a key is inserted and turned. The forced unlocking switch 36 is a switch that can be operated from the outside by a manager of the multi-function toilet 1 or the like to unlock the door 4 when a user of the multi-function toilet 1 is unable to open the electric lock 14 on the door 4 from the inside. The forced unlocking switch 36 has a first contact that is normally connected and a second contact that is connected during forced unlocking, and outputs a forced unlocking signal when the first contact is disconnected.

[0018] Next, the electrical configuration of the automatic door system 5 will be described with reference to Figure 3. The automatic door system 5 includes a door engine 11 that drives the door 4 to open or close, an auxiliary sensor 13, an electric lock 14, a door controller 10 to which these devices are connected, an object detection sensor 12, a occupancy sensor 15, an emergency switch 16, a status determination unit 17, an alarm unit 18, and an operation controller 20 to which the outer door operation unit 30 and the inner door operation unit 40 are connected. The door controller 10, the operation controller 20, the object detection sensor 12, the occupancy sensor 15, the emergency switch 16, the status determination unit 17, and the alarm unit 18 are connected to a CAN 50. When the auxiliary sensor 13 detects something, it transmits a detection signal to the door controller 10. When the object detection sensor 12 and the occupancy sensor 15 detect something, they transmit detection signals to the door controller 10 and the operation controller 20 via the CAN 50. The door controller 10 controls the driving of the door engine 11 in accordance with the detection results of the operation controller 20, the auxiliary sensor 13, and the presence sensor 15. The door engine 11 of this embodiment is an example of a driving mechanism.

[0019] The door controller 10 includes a calculation unit, a communication interface unit, a volatile storage unit, and a nonvolatile storage unit. The calculation unit is a computer processor that controls the door engine 11 according to a control program stored in the nonvolatile storage unit (storage medium). The calculation unit may implement at least a portion of its processing using a circuit such as an ASIC. The control program may be executed by one or more computer processors. The door controller 10 may be configured as one or more processors that execute various processes according to a computer program (software). The processing executed by the door controller 10, i.e., the processor, includes a control method for the door controller 10. The door controller 10 may also be configured as one or more dedicated hardware circuits, such as an application-specific integrated circuit (ASIC), or a circuit including a combination thereof, that executes at least a portion of the various processes. The processor includes a CPU and memories such as RAM and ROM. The memory stores program code or instructions configured to cause the CPU to execute the processes. Memory or computer-readable media includes any available media that can be accessed by a general purpose or special purpose computer.

[0020] The operation controller 20 includes a calculation unit, a communication interface unit, a volatile storage unit, and a nonvolatile storage unit. The calculation unit is a computer processor that controls the outer door operation unit 30 and the inner door operation unit 40 according to a control program stored in the nonvolatile storage unit (storage medium). The calculation unit may implement at least a portion of its processing using a circuit such as an ASIC. The control program may be executed by one or more computer processors. The operation controller 20 may be configured as one or more processors that execute various processes according to a computer program (software). The processing executed by the operation controller 20, i.e., the processor, includes a control method for the operation controller 20. The operation controller 20 may also be configured as one or more dedicated hardware circuits, such as an application-specific integrated circuit (ASIC), or a circuit including a combination thereof, that executes at least a portion of the various processes. The processor includes a CPU and memories such as RAM and ROM. The memory stores program code or instructions configured to cause the CPU to execute the processes. The memory, i.e., computer-readable medium, includes any available medium that can be accessed by a general-purpose or special-purpose computer. The program stored in the computer-readable medium includes a control program for the operation controller 20. The operation controller 20 in this embodiment is an example of an instruction control unit. The operation controller 20 in this embodiment is provided separately from the outer door operation unit 30 and the inner door operation unit 40.

[0021] The operation controller 20 includes an operation control unit 21 and a storage unit 22. The storage unit 22 stores programs for generating various signals and audio data for operation guidance and warning messages tailored to various situations. The operation control unit 21 provides operation guidance for the operation switches by outputting audio from the outer speaker 35 and the inner speaker 45. The operation control unit 21 provides operation guidance when the object detection sensor 12 enters a detection state.

[0022] When the outside open switch 31 detects a pushing operation (opening operation) by the user, it outputs an outside open signal to the operation controller 20. When the outside close switch 32 detects a pushing operation (closing operation), it outputs an outside close signal to the operation controller 20. In response to receiving the outside open signal and the outside close signal from the outside open switch 31 and the outside close switch 32, the operation control unit 21 of the operation controller 20 outputs an outside open instruction signal and an outside close instruction signal to the CAN 50, respectively.

[0023] When the inside opening switch 41 detects a pushing operation (opening operation) by the user, it outputs an inside opening signal to the operation controller 20. When the inside closing switch 42 detects a pushing operation (closing operation), it outputs an inside closing signal to the operation controller 20. In response to receiving the inside opening signal and the inside closing signal of the inside opening switch 41 and the inside closing switch 42, the operation control unit 21 of the operation controller 20 outputs an inside opening instruction signal and an inside closing instruction signal to the CAN 50, respectively. The outside opening instruction signal and the inside opening instruction signal of this embodiment are examples of an opening instruction signal. The outside closing instruction signal and the inside closing instruction signal of this embodiment are examples of a closing instruction signal. Hereinafter, the outside opening instruction signal and the inside opening instruction signal may be collectively referred to as an opening instruction signal. Hereinafter, the outside closing instruction signal and the inside closing instruction signal may be collectively referred to as a closing instruction signal.

[0024] The door controller 10 includes a drive control unit 10A that controls the drive of the door engine 11 and an electric lock control unit 10B. The drive control unit 10A controls the opening or closing of the door engine 11 based on an open instruction signal or a close instruction signal from the outer door operation unit 30 and the inner door operation unit 40. The drive control unit 10A of this embodiment performs a pressing operation to continuously drive the door 4 in the closing direction when the door 4 is in the fully closed position. This prevents the door 4 from moving in the opening direction from the fully closed position. The electric lock control unit 10B controls the drive of a drive unit (not shown) to lock and unlock the electric lock 14. The electric lock control unit 10B of this embodiment locks the electric lock 14 when the occupancy sensor 15 is in a detection state when the inner close switch 42 is operated and the door 4 reaches the fully closed position. The door controller 10 of this embodiment is an example of a door control unit.

[0025] The state determination unit 17 determines whether or not an open instruction signal or a close instruction signal is normally supplied from the operation controller 20 to the door controller 10 (hereinafter referred to as a normal supply state). The state determination unit 17 of this embodiment determines that the normal supply state is not established when, for example, there is an abnormality in communication between the operation controller 20 and the door controller 10, or when an open instruction signal or a close instruction signal is not generated in the operation controller 20 when an open operation or a close operation is accepted by the door operation unit.

[0026] "When there is an abnormality in the communication between the operation controller 20 and the door controller 10" refers to, for example, when the CAN 50 connecting the door controller 10 and the operation controller 20 is disconnected. For example, the state determination unit 10C periodically transmits a communication confirmation signal to the operation controller 20, and when it does not receive a response signal from the operation controller 20, it determines that there is an abnormality in the communication between the door controller 10 and the operation controller 20.

[0027] "When an open operation or a close operation is accepted by the door operation unit, an open instruction signal or a close instruction signal is not generated in the operation controller 20" means, for example, when an open operation or a close operation is accepted by the door operation unit but the operation controller 20 and the door operation unit cannot communicate with each other due to a disconnection of the communication line connecting the operation controller 20 and the door operation unit. For example, the state determination unit 10C periodically transmits a communication confirmation signal to the outer door operation unit 30 and the inner door operation unit 40, and when it does not receive a response signal from the outer door operation unit 30 and the inner door operation unit 40, it determines that there is an abnormality in the communication between the operation controller 20 and the door operation unit.

[0028] Alternatively, "when an open instruction signal or a close instruction signal is not generated in the operation controller 20 when an open operation or a close operation is accepted by the door operation unit" refers to, for example, when an open operation or a close operation is accepted by the door operation unit, an open signal or a close signal is supplied from the door operation unit to the operation controller 20, but a read error occurs in the program that generates the open instruction signal or the close instruction signal in the memory unit 22. For example, when the state determination unit 10C receives an error signal output from the operation controller 20 when a read error occurs in the memory unit 22, it determines that a read error occurs in the program that generates the open instruction signal or the close instruction signal in the memory unit 22.

[0029] The notification unit 18 includes a speaker 18A, a display 18B, and a communication unit 18C. The notification unit 18 is provided in the vicinity of the multi-function toilet 1. Here, the vicinity of the multi-function toilet 1 includes the inside of the multi-function toilet 1 and the vicinity outside the entrance / exit 2 of the multi-function toilet 1. In this embodiment, the notification unit 18 is provided inside the multi-function toilet 1 and the vicinity outside the entrance / exit 2 of the multi-function toilet 1. For example, the notification unit 18 notifies various kinds of guidance information and advertising information. The notification unit 18 in this embodiment notifies that a confinement prevention operation will be performed if it is determined that the supply state is not normal. The communication unit 18C is configured to be able to communicate with an administrator terminal (not shown) outside the multi-function toilet 1. The administrator terminal is a smartphone, tablet terminal, or the like used by the administrator who manages the multi-function toilet 1.

[0030] When the multi-function toilet 1 is not in use, the automatic door device 5 waits with the door 4 fully closed. When the outside-opening switch 31 is operated, the automatic door device 5 drives the door engine 11 to open the door 4. Note that when the multi-function toilet 1 is not in use, the automatic door device 5 may wait with the door 4 fully open. Next, when the inside-closing switch 42 is operated by a user, the door 4 is closed and the electric lock 14 is locked. After that, even if an open command signal is output from the outside-opening switch 31, the automatic door device 5 will not open the door 4, and only the open command signal from the inside-closing switch 42 will be valid.

[0031] Next, the processing procedure of the automatic door system 5 will be described with reference to Fig. 4. The automatic door system 5 performs the following processing at predetermined timings.

[0032] In step S101, the state determination unit 10C determines whether or not the state is a normal supply state. If the state is a normal supply state (Y in step S101), the process S100 ends. If the state is not a normal supply state (N in step S101), the process S100 proceeds to step S103.

[0033] In step S102, the door controller 10 executes a confinement prevention operation to prevent a person from being confined in the multi-function toilet 1.

[0034] FIG. 5 is a flowchart showing the confinement prevention operation in step S102 of the process S100 of the automatic door system according to the embodiment.

[0035] In step S201, the drive control unit 10A determines whether the door 4 is in the fully closed position. For example, the door controller 10 determines whether the door 4 is in the fully closed position based on the output value of the encoder of the motor of the door engine 11. If the door 4 is in the fully closed position (Y in step S201), step S102 proceeds to step S202.

[0036] In step S202, the electric lock control unit 10B determines whether the electric lock 14 is locked. If the electric lock 14 is not locked (N in step S202), step S102 proceeds to step S204. If the electric lock 14 is locked (Y in step S202), step S102 proceeds to step S203.

[0037] In step S203, the electric lock control unit 10B unlocks the electric lock 14.

[0038] In step S204, the drive control unit 10A restricts the drive of the door engine 11. In this embodiment, the drive control unit 10A stops the drive of the door engine 11. For example, the drive control unit 10A stops the pushing action of the door 4, which is in the fully closed position, and puts the door 4 in a state where the door engine 11 is not generating a driving force. This makes it possible to pry open the door 4 from inside or outside the multi-function toilet 1. After step S204, step S102 proceeds to step S206.

[0039] Returning to step S201, if the door 4 is not in the fully closed position (N in step S201), step S102 proceeds to step S205. In step S205, the drive control unit 10A moves the door 4 to the fully open position. For example, if the drive control unit 10A determines in step S101 that the normal supply state is not occurring while the door 4 is moving to the closed position, the drive control unit 10A reverses the closing movement of the door 4 and moves it to the open position, thereby moving the door 4 to the fully open position. For example, if the drive control unit 10A determines in step S101 that the normal supply state is not occurring while the door 4 is moving to the open position, the drive control unit 10A moves the door 4 to the fully open position by continuing to move it to the open position. For example, if the drive control unit 10A determines in step S101 that the normal supply state is not occurring while the door 4 is in the fully open position, the drive control unit 10A maintains the position of the door 4 in the fully open position.

[0040] In step S206, the drive control unit 10A invalidates the close instruction signal. For example, if only one of the outer door operation unit 30 and the inner door operation unit 40 has an abnormality in communication with the operation controller 20, and the other performs a close operation and outputs a close instruction signal, the drive control unit 10A invalidates the close instruction signal. Here, the drive control unit 10A “invalidating the close instruction signal” refers to the drive control unit 10A receiving a close instruction signal but not closing the door 4 and maintaining the door 4 in its position. Note that if the other performs an open operation and outputs an open instruction signal, the open instruction signal functions validly. However, if the inner door operation unit 40, of the outer door operation unit 30 and the inner door operation unit 40, has an abnormality in communication with the operation controller 20, and a user is present in the multi-function toilet 1, even if the outer door operation unit 30 performs an open operation and outputs an open instruction signal, the open instruction signal is invalid as in normal operation. After step S206, step S102 ends, and the process S100 proceeds to step S103.

[0041] 4, in step S103, the notification unit 18 notifies that a confinement prevention operation will be performed. For example, the notification unit 18 outputs a message such as "There is a risk that the indoor and outdoor door switches will not work, so indoor confinement prevention operation will be started" through the speaker 18A and displays it on the display 18B. The notification unit 18 also notifies the administrator terminal via the communication unit 18C that the communication state is unstable.

[0042] In step S104, the state determination unit 10C determines whether the normal supply state has been restored. For example, even after determining that the normal supply state is not established, the state determination unit 10C continues to periodically send a communication confirmation signal to the operation controller 20. When the state determination unit 10C receives a response signal from the operation controller 20, the state determination unit 10C determines that the abnormality in communication between the door controller 10 and the operation controller 20 has been resolved and the normal supply state has been restored. Also, for example, when the manager of the multi-function toilet 1 inspects the abnormal part, communication between the door controller 10 and the operation controller 20 becomes normal, and a specific operation is performed by the manager via the manager's terminal, the state determination unit 10C determines that the normal supply state has been restored. If the normal supply state has not been restored (N in step S104), the process S100 returns to step S104. If the normal supply state has been restored (Y in step S104), the process S100 proceeds to step S105.

[0043] In step S106, the door controller 10 ends the confinement prevention operation, and then returns to normal operation.

[0044] In step S107, the notification unit 18 ends the notification that the confinement prevention operation will be performed. After step S107, the process S100 ends.

[0045] As described above, in the embodiment, the automatic door system 5 includes a door control unit that controls the drive mechanism that opens or closes the door 4 provided at the opening of a private room based on an open instruction signal or a close instruction signal, an operation reception unit that receives an open or close operation of the door 4 by a user, an instruction control unit that outputs an open instruction signal or a close instruction signal in response to receiving the open or close operation, and a status determination unit 10C that determines whether the open instruction signal or the close instruction signal is being normally supplied from the instruction control unit to the door control unit. If the status determination unit 10C determines that the signal is not being normally supplied, the door control unit performs a confinement prevention operation to prevent a person from being confined in the private room. With this configuration, the confinement prevention operation can be performed when the open instruction signal or the close instruction signal is not normally supplied to the door control unit, making it possible to prevent a person from being confined in the private room.

[0046] In the embodiment, the door control unit limits the driving of the drive mechanism as a confinement prevention operation. With this configuration, the door 4 can be opened manually, thereby preventing the user from being confined inside the multi-function toilet 1.

[0047] In this embodiment, the door control unit controls the drive mechanism to move the door 4 to the fully open position as a confinement prevention operation. This configuration prevents people from being confined inside the multi-function toilet 1 and also prevents the multi-function toilet 1 from being used in a state where there is a risk of being confined. In this case, after the door 4 has moved to the fully open position, the door 4 may continue to be driven in the opening direction to maintain the door 4 in the fully open position.

[0048] The door control unit terminates the confinement suppression operation when it is determined that the state of normal supply has returned after it was determined that the state of normal supply was not in effect. This configuration saves the manager of the multi-function toilet 1 from having to perform the operation to terminate the confinement suppression operation when the transition to the confinement suppression operation occurs due to a temporary communication failure.

[0049] In this embodiment, the automatic door system 5 includes a notification unit 18 that notifies the user that a confinement prevention operation will be performed if it is determined that the supply of food is not normal. This configuration allows the user who receives the notification to understand that a confinement prevention operation will be performed.

[0050] In the embodiment, the state determination unit 10C determines that the state is not capable of normal output when there is an abnormality in communication between the instruction control unit and the door control unit, or when the instruction control unit does not generate an open instruction signal or a close instruction signal when the instruction control unit accepts an open operation or a close operation. With this configuration, it is possible to effectively prevent a person from being trapped in a private room.

[0051] Variations Modifications of the embodiment will be described below. The above embodiment can be modified as follows: The above embodiment and the following modifications can be combined with each other within the scope of technical compatibility.

[0052] In the embodiment, the operation controller 20 is provided separately from the outer door operation unit 30 and the inner door operation unit 40, but this is not limiting. For example, the operation controller 20 may be provided integrally with one of the outer door operation unit 30 and the inner door operation unit 40. Fig. 6 illustrates this modified example. As shown in Fig. 6, for example, the operation controller 20 may be provided in the outer door operation unit 30, and signals based on various operations received by the inner door operation unit 40 may be transmitted to the door controller 10 via the outer door operation unit 30.

[0053] In the embodiment, the state determination unit 10C is provided integrally with the door controller 10, but is not limited to this and may be provided separately from the door controller 10. Also, for example, the door controller 10 may be provided with a state determination unit for determining the communication state between the door controller 10 and the operation controller 20, and a state determination unit for determining whether an open instruction signal or a close instruction signal is generated in the operation controller 20 when an open operation or a close operation is accepted by the door operation unit.

[0054] In the embodiment, the automatic door system 5 has the electric lock 14, but is not limited to this and may not have the electric lock 14. In this case, the electric lock does not have to be unlocked in steps S202 and S203.

[0055] In the embodiment, the auxiliary sensor 13 is installed on the inner wall of the entrance / exit 2, but an auxiliary sensor may be installed at each of the inside and outside of the door 4. In this case, it is possible to reliably detect a person who may come into contact with the closing door 4.

[0056] In the embodiment, the object detection sensor 12 and the occupancy sensor 15 are provided together, but either one or both may be omitted. If the object detection sensor 12 is not provided, the operation control unit 21 may continue to provide operation guidance at regular time intervals. If the occupancy sensor 15 is not provided, the occupancy may be determined based on whether the auxiliary sensor 13 detects something.

[0057] In the embodiment, the object detection sensor 12 is attached to the door handle of the automatic door system 5, but the object detection sensor 12 may also be attached to the outer door operating unit 30. In addition, the outer speaker 35 or a display integrally provided on the outer door operating unit 30 may function as the notification unit 18.

[0058] In the embodiment, the sensor attached to the blind of the automatic door device 5 is used as the object detection sensor 12, but the sensor attached to the blind may also be used as an open protection sensor that detects people or objects that may come into contact with the opening door 4, a close protection sensor that detects people or objects that may come into contact with the closing door 4, or an entry detection sensor that determines whether a person has entered a private room.

[0059] In the embodiment, the state determination unit 10C determines that the normal supply state has been restored when it receives a response signal from the operation controller 20, but it may also determine that the normal supply state has been restored only when the number of times the response signal has been received from the operation controller 20 exceeds a reference value.

[0060] Any combination of the above-described embodiments and modifications is also useful as an embodiment of the present invention. A new embodiment resulting from the combination has the combined effects of the combined embodiments and modifications.

[0061] Among the embodiments disclosed in this specification, those in which multiple functions are provided in a distributed manner may have some or all of the multiple functions integrated together, and conversely, those in which multiple functions are provided in a distributed manner may have some or all of the multiple functions integrated together. Regardless of whether the functions are integrated or distributed, it is sufficient that the configuration can achieve the object of the invention. [Explanation of symbols]
