Description

Control System and Control Method

[0001] The present disclosure relates to a control system to be installed for a door body including a frame and a main body provided inside the frame so as to be openable and closable.

[0002] Some door bodies have an authentication unit such as a face recognition device on the outdoor side inside the door body.

[0003] Japanese Unexamined Patent Application Publication No. 2024 - 115366

[0004] Some of the authentication units are configured to set a password such as an administrator password at the first startup. The present inventors focused on the following problem that can occur in a door body having such an authentication unit on the outdoor side. That is, before the delivery of the property including the door body, when the power switch such as a breaker is turned on to supply power to the control system of the door body, the authentication unit is activated and the password can be input. Since the authentication unit is on the outdoor side, there is a risk that the password may be set arbitrarily by mischief of an outsider or the like. And in such an authentication unit, once the password is set, there are cases where the password cannot be reset without inputting the original password, or even if it can be reset, a very complicated operation may be required.

[0005] And the same problem can occur in predetermined devices on the outdoor side other than the authentication unit. That is, also in the predetermined device, there is a risk that predetermined operations such as various setting changes may be arbitrarily made by mischief of an outsider or the like.

[0006] The present disclosure has been made in view of the above circumstances, and an object thereof is to suppress a predetermined operation from being arbitrarily performed by mischief of a member or the like on a predetermined device on the outdoor side of a door body.

[0007] The control system disclosed herein is a control system that includes a predetermined device accessible from the outside of a door body having a frame and a main body provided inside the frame so as to be openable and closable, and comprises an operating unit provided at a position spaced apart from the predetermined device, and a control unit that is operable by the operating unit and capable of controlling the predetermined device, wherein in a predetermined initial state, when power is supplied to the control unit, a predetermined operation on the predetermined device is disabled, and subject to a predetermined switching operation performed by the operating unit, the system switches from the initial state to a predetermined normal state, and the predetermined operation on the predetermined device becomes possible in the power supply state.

[0008] The control method of the present disclosure is a control method for controlling a predetermined device accessible from the outside of a door body having a frame and a main body provided inside the frame so as to be openable and closable, wherein in a predetermined initial state, when power is supplied to a predetermined control unit, a predetermined operation on the predetermined device is disabled, and on the condition that a predetermined switching operation is performed by an operating unit provided at a position spaced apart from the predetermined device, the system switches from the initial state to a predetermined normal state so that the predetermined operation on the predetermined device becomes possible in the power supply state.

[0009] This is a view of the door body of the embodiment from the outside. This is a view of the door body from the inside. This is a perspective view showing the side panel. This is a circuit diagram showing the initial state before power is supplied to the control system. This is a circuit diagram showing the initial state when power is supplied. This is a circuit diagram showing the normal state when power is supplied.

[0010] The embodiments of this disclosure will be described below with reference to the drawings. However, this disclosure is not limited in any way to the embodiments described below, and may be implemented with appropriate modifications without departing from the spirit of this disclosure.

[0011] [First Embodiment] As shown in Figure 1, the door body 100 comprises a frame 10, a main body 20, and a side section 30. The main body 20 is installed inside the frame 10 so as to be openable and closable. Unless otherwise specified, the positional relationships in the following description refer to the positional relationships when the main body 20 is closed. The side section 30 is installed on the side of the main body 20 inside the frame 10.

[0012] Hereinafter, as shown in Figure 1, the exterior side in the thickness direction of the door panel 100 is referred to as "exterior side Y+". Also, as shown in Figure 2, the interior side in the thickness direction of the door panel 100 is referred to as "interior side Y-". Furthermore, the side of the door panel 100 that goes from the side panel 30 toward the main body 20 in the width direction is referred to as "main body side X-" or "opposite side of side panel X+ (X-)". Furthermore, the side of the door panel 100 that goes from the main body 20 toward the side panel 30 in the width direction is referred to as "side panel side X+" or "opposite side of main body side X- (X+)".

[0013] As shown in Figure 1, a control system 80 is provided in the sleeve portion 30. As shown in Figure 6, the control system 80 comprises a control unit 40, an authentication unit 33, and an operation unit 60. Power is supplied to the control unit 40 from the power supply 110. Power is supplied from the control unit 40 to the authentication unit 33 and the operation unit 60, respectively. The control unit 40 is configured to be operable by the operation unit 60 and to control the authentication unit 33.

[0014] The authentication unit 33 shown in Figure 1 is a facial recognition device or a fingerprint recognition device, and is configured to be accessible by a user from the outside Y+. When the authentication unit 33 is powered on and started up, in its initial state where no password such as an administrator password has been set, it becomes possible to set a password. Note that "authentication unit 33" may be read as "specified device". Also, "password setting" may be read as "specified operation".

[0015] As shown in Figure 3, an operating section 60 is provided on the visible surface of the sleeve portion 30 on the main body side X+. Therefore, users cannot access the operating section 60 when the main body 20 is closed, but they can access the operating section 60 when the main body 20 is open. Hereafter, as shown in Figure 5, the state in which power is supplied to the control unit 40, such as when the power switch 120 of the circuit breaker is ON, is referred to as the "power supply state".

[0016] The operation unit 60 is configured to switch the control unit 40 between an initial state St0 shown in Figure 5 and a normal state St1 shown in Figure 6. The initial state St0 shown in Figure 5 is a state in which the control unit 40 does not supply power to the authentication unit 33 when power is supplied. On the other hand, the normal state St1 shown in Figure 6 is a state in which the control unit 40 supplies power to the authentication unit 33 when power is supplied.

[0017] In other words, the authentication unit 33 switches from the initial state St0 shown in Figure 5 to the normal state St1 shown in Figure 6, provided that a predetermined switching operation is performed by the operation unit 60 shown in Figure 3. As a result, the authentication unit 33 is powered on and starts up. This makes it possible to set a password in the authentication unit 33.

[0018] The authentication unit 33 maintains the normal state St1 even after it has switched from the initial state St0 shown in Figure 5 to the normal state St1 shown in Figure 6, and then the power supply to the control unit 40 is turned off and then on again.

[0019] The control unit 40 is configured to temporarily supply power to the authentication device 33 when performing installation verification of the door body 100, even if no switching operation has been performed. Specifically, for example, when the person performing the installation verification operates the operation unit 60 to select a predetermined installation verification mode, the control unit 40 temporarily supplies power to the authentication device 33.

[0020] Furthermore, the control performed by the control system 80 described above constitutes the implementation of the control method.

[0021] Next, this embodiment will be described in more detail.

[0022] As shown in Figure 1, an outdoor handle 23 is provided at the end of the sleeve portion side X+ on the outdoor side Y+ of the main body 20. The end of the main body 20 opposite to the sleeve portion side X+ (X-) is rotatably attached to the frame 10 via a hinge or the like.

[0023] The sleeve portion 30 may be a sub-door that can be opened and closed, or a fixed sleeve portion that cannot be opened and closed. If the sleeve portion 30 is a sub-door, the end of the sleeve portion 30 opposite to the main body side X- (X+) is rotatably attached to the frame 10 via a hinge or the like.

[0024] The aforementioned authentication unit 33 is attached to the outdoor side Y+ of the sleeve portion 30. Furthermore, the sleeve portion 30 is provided with an upper locking / unlocking unit 50u and a lower locking / unlocking unit 50d, arranged vertically. Hereinafter, the upper locking / unlocking unit 50u and the lower locking / unlocking unit 50d will simply be referred to as "locking / unlocking unit 50".

[0025] Each upper and lower locking / unlocking unit 50 comprises a lock 54, a cylinder 53, and a locking / unlocking device 55. The lock 54 is configured to be lockable and unlockable when the main body 20 is closed. The cylinder 53 is configured to allow manual operation of the lock 54 using a key from the outside Y+. The locking / unlocking device 55 is configured to allow electric operation of the lock 54. Hereinafter, unlocking the lock 54 by the locking / unlocking device 55 will be referred to as "electric unlocking," and locking the lock 54 by the locking / unlocking device 55 will be referred to as "electric locking."

[0026] As shown in Figure 2, an outdoor handle 23 is provided at the end of the sleeve portion X+ on the indoor side Y- of the main body 20. An open switch 37, for example, is attached to the indoor side Y- of the sleeve portion 30.

[0027] Each locking / unlocking unit 50 is further equipped with a thumbturn 57. The thumbturn 57 is configured to allow manual operation of the lock from the interior side Y-. The aforementioned locking / unlocking device 55 may be, for example, part of the thumbturn 57 or part of the lock 54. In other words, the thumbturn 57 may be an electric thumbturn, and the lock 54 may be an electric lock.

[0028] An opening / closing device 90 is attached to the upper part of the main body 20 on the indoor side Y-. The opening / closing device 90 is configured to allow the main body 20 to be opened and closed electrically. Hereinafter, opening the main body 20 by the opening / closing device 90 will be referred to as "electric opening," and closing the main body 20 by the opening / closing device 90 will be referred to as "electric closing."

[0029] In this embodiment, the opening and closing device 90 is configured such that an electric opener capable of electrically opening the door and an electric closer capable of electrically closing the door are integrally formed. However, alternatively, the opening and closing device 90 may be configured such that the electric opener and the electric closer are formed separately.

[0030] In addition to the authentication unit 33, the control unit 40 controls the locking / unlocking device 55 and the opening / closing device 90, etc. The control unit 40 is mainly composed of, for example, a predetermined computer and a predetermined control program.

[0031] When the authentication unit 33 shown in Figure 1 authenticates that the person on the outside side Y+ of the door 100 is a registered person, the control unit 40, for example, electrically unlocks and electrically opens the door. Subsequently, the control unit 40, for example, electrically closes and electrically locks the door at a predetermined timing.

[0032] When the door open switch 37 shown in Figure 2 is pressed, the control unit 40, for example, electrically unlocks and electrically opens the door. Subsequently, the control unit 40, for example, electrically closes and electrically locks the door at a predetermined timing.

[0033] As shown in Figure 3, the operation unit 60 includes, for example, an upper display unit 63, a lower display unit 64, an upper switch 65, and a lower switch 66. By operating the upper switch 65, the numbers, symbols, etc., displayed on the upper display unit 63 can be changed. By operating the lower switch 66, the numbers, symbols, etc., displayed on the lower display unit 64 can be changed. By changing these numbers, symbols, etc., various settings for the control unit 40 can be changed. Thus, the operation unit 60 can be used to perform various operations on the control unit 40, including the aforementioned switching operations.

[0034] As shown in Figure 4, the control unit 40 is electrically connected to the power supply 110 via a power switch 120 such as a circuit breaker. Therefore, as shown in Figure 5, when the power switch 120 is turned ON, power is supplied. In the initial state St0 shown in Figure 5, the control unit 40 supplies power to electrical equipment other than the authentication unit 33, such as the operation unit 60, but does not supply power to the authentication unit 33. On the other hand, in the normal state St1 shown in Figure 6, the control unit 40 supplies power to each electrical device, including the authentication unit 33.

[0035] The configuration and effects of this embodiment are summarized below.

[0036] The authentication unit 33 shown in Figure 1 allows password setting when power is supplied and the unit is started up, even if no password such as an administrator password has been set. The authentication unit 33 is located on the outdoor side Y+. Therefore, if the power switch 120, such as a circuit breaker, is turned ON and power is supplied, there is a risk that the password could be set arbitrarily by tampering with the unit by an employee or other person.

[0037] In this respect, in the initial state St0 shown in Figure 5 of this embodiment, even if the power switch 120 is ON and power is supplied, no power is supplied to the authentication unit 33. As a result, the authentication unit 33 does not start up, and it is impossible to set a password. Therefore, there is no need to worry about unauthorized persons entering passwords for mischief or other reasons.

[0038] The control unit 40 is configured to be able to temporarily supply power to the authentication unit 33 when performing installation verification of the door panel 100, even if no switching operation has been performed. Therefore, the authentication unit 33 can perform installation verification of the door panel 100 while ensuring the above-mentioned tamper-proof effect.

[0039] The authentication unit 33 shown in Figure 1 maintains the normal state St1 even if the power supply to the control unit 40 is turned off and then on again after switching from the initial state St0 shown in Figure 5 to the normal state St1 shown in Figure 6. Therefore, even if the power supply to the control unit 40 is temporarily interrupted due to a power outage or the like, there is no need to worry that the authentication unit 33 will revert to the initial state St0 shown in Figure 5 and fail to start up when the power outage is resolved.

[0040] The operating unit 60 shown in Figure 3 is inaccessible when the main unit 20 is closed, as shown in Figure 1, but is accessible when the main unit 20 is open, as shown in Figure 3. When a predetermined switching operation is performed using the operating unit 60, the authentication unit 33 switches from the initial state St0 shown in Figure 5 to the normal state St1 shown in Figure 6 and activates. This enables the authentication unit 33 to set a password. Therefore, a configuration can be easily implemented where only those who can unlock and open the door 100 can operate the operating unit 60 to set a password.

[0041] As shown in Figure 1, the control unit 40 and the authentication unit 33 are located on the exterior side Y+ of the side section 30. As shown in Figure 3, the operating unit 60 is located on the main body side X+ of the side section 30. This allows all components of the control system 80 to be located in the side section 30, thereby improving the aesthetic design of the door body 100.

[0042] [Other Embodiments] The above embodiments can be implemented with modifications as follows, for example.

[0043] The authentication unit 33 shown in Figure 1 may be provided on the main body 20 or frame 10 of the door body 100, or it may be provided outside the frame 10. There may be only one locking / unlocking unit 50. Also, the control unit 40 may be provided in a location other than the side panel 30.

[0044] Instead of the door opening switch 37 shown in FIG. 2, a non-contact sensor that is detected when the user U holds a hand over it may be provided. Based on the detection by the non-contact sensor, electric unlocking and electric door opening from the indoor side Y− may be performed. Also, when the door opening switch 37 is not provided, the electric locking / unlocking and opening / closing from the indoor side Y− may be configured to be performed based on an operation such as a remote control key. Further, instead of the opening / closing device 90, a normal closer may be provided on the door body 100. And the user U may be configured to manually open the door of the main body 20.

[0045] The operation unit 60 shown in FIG. 3 may be provided on the prospective surface of the sleeve part side X+ in the main body 20 shown in FIG. 2. Also, the operation unit 60 may be provided at a position accessible from the indoor side Y−, such as the indoor side Y− of the sleeve part 30. In this case, a configuration in which only a person entering the indoor side Y− can operate the operation unit 60 to set a password can be simply realized. Also, the operation unit 60 may be provided at a position that an outsider on the outdoor side Y+ cannot know.

[0046] The initial state St0 shown in FIG. 5 may be set to a state in which power is supplied to the authentication unit 33 but a password cannot be set. Even in this case, the authentication unit 33 becomes able to set a password on the condition that a switching operation is performed by the operation unit 60.

[0047] Instead of or in addition to the authentication unit 33 shown in FIG. 6, for a predetermined device other than the authentication unit 33 such as a door phone, it may be switched from the initial state St0 to the normal state St1 on the condition that a predetermined switching operation is performed by the operation unit 60. And by that switching, setting of a password and other predetermined operations may be made possible. In this case, for the predetermined device other than the authentication unit 33, situations such as a password being set arbitrarily due to mischief or other predetermined operations being performed arbitrarily can be prevented.

[0048] In this case, if the authentication unit 33 is not provided, the unlocking and locking and opening and closing by power from the outdoor side Y+ may be configured to be performed based on an operation of a remote control key or the like.

[0049] 10... frame body, 20... main body, 30... sleeve part, 33... authentication unit (predetermined device), 60... operation unit, 100... door body, St0... initial state, St1... normal state, X−... main body side, X+... sleeve part side, Y−... indoor side, Y+... outdoor side.
