Description

Automatic door device and control method of automatic door device

The present invention relates to an automatic door device and a control method for the automatic door device.

Conventionally, an automatic door device that automatically opens and closes a sliding door of a specific facility such as a multi-function toilet according to a user's operation is known. The automatic door device includes a contact-type command output unit such as a push button that outputs an open / close command for a sliding door according to a user's operation. The automatic door device opens and closes the sliding door in response to a command.

In recent years, there has been an increasing demand for adopting non-contact type command output means for automatic door devices from various viewpoints including hygiene. As a non-contact type command output means, for example, an infrared projection type sensor as described in Patent Document 1 is known.

Japanese Unexamined Patent Publication No. 2011-006981

By applying the non-contact type command output means to the automatic door device, the user can open and close the sliding door without touching the command output means. However, unlike the contact-type command output means, the non-contact type command output means cannot visually or tactilely recognize the operation result of the command output means by the user himself / herself. As a result, the operation intended by the user may not match the command recognized by the automatic door device. Therefore, if the control system of the automatic door device having only the contact type command output unit is directly diverted to the automatic door device having the non-contact type command output unit, the frequency of the automatic door device performing an unintended operation by the user is high. It gets higher.

The present disclosure is to solve such a problem, and an object of the present invention is to provide a technique capable of reducing the frequency of unintended operations of the user in an automatic door device having a non-contact type command output unit.

According to one aspect of the present invention, a door separating the indoor and outdoor areas, a non-contact type open command output unit provided on the indoor side and outputting an open command in response to an operator's operation, and a non-contact type open command output unit provided on the indoor side. A non-contact type close command output unit that outputs a close command according to the operation of the operator, and an open command output from the open command output unit or a door open drive based on the close command output from the close command output unit. Or, if a control unit for driving the door is provided and one of the open command and the closed command is output and the other of the open command and the closed command is output within a predetermined time when the door is in the non-drive state, the other is output. The control unit is provided with an automatic door device that keeps the door in a non-driving state.

Hereinafter, the present invention will be described based on a preferred embodiment with reference to the drawings. The same or equivalent components, members, and processes shown in the drawings shall be designated by the same reference numerals, and duplicate description thereof will be omitted as appropriate. Further, the embodiment is not limited to the invention, but is an example, and all the features and combinations thereof described in the embodiment are not necessarily essential to the invention.

In the embodiment, an automatic door device provided at the entrance / exit of a multi-functional toilet will be described. The automatic door device can be applied not only to a multi-function toilet but also to various places where open / close switches are arranged on both sides of the sliding door of the automatic door device, such as a factory entrance / exit.

[First Embodiment]
FIG. 1 is a front view of the automatic door device, and FIG. 2 is a plan view of a multi-function toilet in which the automatic door device is installed. As shown in FIGS. 1 and 2, the automatic door device 10 is installed at the doorway 16 of the multi-functional toilet 14 surrounded by walls 12 on all sides. The automatic door device 10 includes a fixing portion 18, a sliding door 20, and a transom 22. The fixing portion 18 is fixed to the wall 12 and visually blocks the space between the transom 22 and the floor surface. The sliding door 20 moves horizontally with respect to the fixed portion 18 between the open state and the closed state. The sliding door 20 overlaps with the fixed portion 18 in the open state when viewed from the front (direction in FIG. 1), and the side entrance 16 (opening) of the fixed portion 18 opens when the sliding door 20 is in the open state. The sliding door 20 lays side by side with the fixed portion 18 in the closed state and closes the doorway 16. In this example, the sliding door 20 is provided on the indoor side of the multi-functional toilet 14, and is arranged so as to face the indoor surface of the fixed portion 18 in the open state. However, the sliding door 20 may be provided on the outdoor side and arranged so as to face the outdoor surface of the fixing portion 18 in the open state.

In the multi-functional toilet 14, facilities such as a washbasin 24, a toilet bowl 26, and a diaper changing table 28 used by the user are provided. In the present embodiment, the wash basin 24 and the toilet bowl 26 are arranged on the back side of the private room away from the automatic door device 10. Further, in the present embodiment, the diaper changing table 28 is arranged on the front side (automatic door device side) of the private room as shown in the figure. In the vicinity of the automatic door device 10, a detection area 30 for a protection sensor of the automatic door device 10, which will be described later, is provided. The detection area 30 includes an outdoor closed detection area A2 on the outdoor side of the opening of the automatic door device, an indoor closed detection area A3 on the indoor side of the opening, and an open detection area A4. The detection area will be described later together with the configuration of the transom 22. Hereinafter, in the present specification, when the outdoor closed detection area A2 and the indoor closed detection area A3 are not distinguished, they may be collectively referred to as “close detection areas A2 and A3”.

The automatic door device 10 includes a command output unit 36 (corresponding to a non-contact type command output unit) that outputs an open command or a close command of the sliding door 20 according to the operation of the user. The command output unit 36 includes an outdoor command output unit 36o provided on the outdoor side and an indoor command output unit 36i provided on the indoor side. The indoor command output unit 36i and the outdoor command output unit 36o are provided near the entrance / exit 16, respectively. Each of the outdoor command output unit 36o and the indoor command output unit 36i includes an open sensor 38 and a closed sensor 40. When the user is trying to open the sliding door 20 or to close the sliding door 20, the open sensor 38 and the closed sensor 40 are approached by a part of the body such as a hand. It is an infrared projection type sensor that detects. For example, when the user brings his / her hand close to the open sensor 38 and enters within the detection range of the open sensor 38, the open sensor 38 turns on the detection signal. On the other hand, the open sensor 38 turns off the detection signal while the user's body or the like is not detected within the detection range of the open sensor 38. Hereinafter, in the present specification, the open sensor 38 may be referred to as an open sensor 38i when referring to the open button on the indoor side, and may be referred to as an open sensor 38o when referring to the open sensor on the outdoor side. The closed sensor 40 may also be referred to as a closed sensor 40i or a closed sensor 40o.

Capacitance type sensors may be used as the open sensor 38 and the closed sensor 40. The capacitance type sensor forms a magnetic field as a detection region, and determines whether or not a person or an object is detected in the detection region according to the amount of change in the capacitance in the magnetic field. In this case, the capacitance type sensor determines that a person or an object has been detected in the detection region when the amount of change in capacitance exceeds a predetermined threshold value. By setting the threshold value, the operation accuracy can be further improved.

The automatic door device 10 includes an auxiliary photoelectric sensor 42 having a detection area A1 in the doorway 16. The auxiliary photoelectric sensor 42 includes a light emitting unit 44 and a light receiving unit 46. The light projecting unit 44 and the light receiving unit 46 are arranged on opposite sides in the width direction with the entrance / exit 16 interposed therebetween, and the space between them serves as a detection area (auxiliary detection area) A1 of the auxiliary photoelectric sensor 42. The auxiliary photoelectric sensor 42 irradiates the light from the light emitting unit 44 toward the light receiving unit 46, and a person or an object exists in the auxiliary detection area A1 depending on whether the light is received (detected) by the light receiving unit 46. Is detected. The automatic door device 10 can detect whether a person or an object is present in the auxiliary detection area A1 of the auxiliary photoelectric sensor 42 based on the detection result of the auxiliary photoelectric sensor 42.

The transom 22 is arranged above the doorway 16 and incorporates a control mechanism for the sliding door 20 including the protection sensor 48 and the like described above. On the surface of the transom light 22, an outdoor closed protection sensor 50o having a detection area (outdoor closed detection area A2) on the outdoor side of the doorway 16 and a detection area (indoor closed detection area A3) on the indoor side of the doorway 16 The indoor side closed protection sensor 50i and the open protection sensor 52 having a detection area (open detection area A4) overlapping with the position where the sliding door 20 in the open state stands by are provided. In the present specification, the outdoor closed protection sensor 50o, the indoor closed protection sensor 50i, and the open protection sensor 52 may be collectively referred to as a protection sensor 48. Further, the outdoor closed protection sensor 50o and the indoor closed protection sensor 50i may be collectively referred to as a closed protection sensor 50.

Each protection sensor 48 is composed of a near-infrared sensor that projects near-infrared rays toward the corresponding detection areas A2 to A4 and receives the reflected light. More specifically, the protection sensor 48 is provided with a plurality of near-ultraviolet sensors corresponding to each of the small detection areas by dividing the detection areas A2 to A4 into a plurality of small detection areas. Basically, when a person or an object is detected in any of the small detection areas, the protection sensor 48 determines that the person or the object is detected in the detection areas A2 to A4.

FIG. 3 is a block diagram of the control mechanism of the automatic door device.

As shown in FIG. 3, the automatic door device 10 includes a multi-function toilet automatic door controller (hereinafter, may be simply referred to as a “door controller”) 54 as a control unit, a door controller 56, and a notification unit 58. Be prepared. The door controller 54 is a controller for realizing a function peculiar to a multi-functional toilet, which is not provided in, for example, an automatic door device for an entrance / exit of a general building. The door controller 54 receives the output results of the open / close sensors 38 and 40 and supplies a drive command for the sliding door 20 to the door controller 56. In addition to this, the door controller 54 gives a predetermined notification to the user via the notification unit 58. Further, the door controller 54 may read out the detection result of the protection sensor 48 as necessary and supply a drive command for the sliding door 20 to the door controller 56 based on the detection result.

The door controller 54 enables outputs (that is, open command or close command) from the open sensors 38i and 38o and the close sensors 40i and 40o according to the state of the sliding door 20 and the indoor conditions of the multi-functional toilet 14. Or disable it. The state of the sliding door 20 includes a fully open state, a fully closed state, an open operation state from the fully closed state to the fully open state, and a closed operation state from the fully open state to the fully closed state. The indoor condition of the multi-functional toilet 14 means the presence or absence of a user in the multi-functional toilet 14. As a method for the door controller 54 to determine the indoor situation in the multi-functional toilet 14, a human sensor is provided in the multi-functional toilet 14, and there is a user in the room based on the output history of the command output unit 36. There is a way to estimate. For example, when the final operation history of the sliding door 20 is a closing command output from the closing sensor 40o on the outdoor side, the door controller 54 estimates that there is no person in the multi-functional toilet 14. On the other hand, when the final operation history of the sliding door 20 is the closing command output from the closing sensor 40i on the indoor side, the door controller 54 presumes that there is a person in the multi-functional toilet 14. To enable or disable the output of the open sensor 38i or the like, the door controller 54 drives the sliding door 20 based on the ON signal or the OFF signal from the open sensor 38i or the like, or the current state is not driven. It means whether to maintain it. Therefore, for example, when the open command from the open sensor 38i is invalidated, the open sensor 38i does not output the open command, or even if the open command is output from the open sensor 38i, the door controller 54 controls based on the open command. Ignore the open command without doing.

Table 1 shows the relationship between the state of the sliding door 20 and the change in the standby state of the door controller 54 when a command is output from the open sensors 38i and 38o and the closed sensors 40i and 40o. A plurality of standby states of the door controller 54 are set in advance according to the state of the sliding door 20 and the indoor state of the multi-functional toilet 14 (whether it is in use or unused). The door controller 54 switches the standby state each time the state of the sliding door 20 and the situation in the multi-function toilet 14 change. The door controller 54 switches between enabling and disabling the outputs of the open sensors 38i and 38o and the closed sensors 40i and 40o according to the standby state.

As shown in Table 1, in a plurality of standby states, when the sliding door 20 is in the fully closed state and at least the outputs of the open sensors 38i and 38o are valid (first standby state), the sliding door 20 is in the open operating state. Yes, and at least when the outputs of the closed sensors 40i and 40o are valid (second standby state), when the sliding door 20 is in the closed operating state, and at least when the outputs of the open sensors 38i and 38o are valid (third standby state). State), when the sliding door 20 is in the fully closed state and the output of the open sensor 38i is valid (fourth standby state), and when the sliding door 20 is in the closed operation state and the output of the open sensor 38i is valid. The case (fifth standby state) is included. In the present embodiment, it is presumed that the multi-function toilet 14 is in an unused state in the first standby state, the second standby state, and the third standby state. In the present embodiment, it is presumed that the multi-function toilet 14 is in the used state in the fourth standby state and the fifth standby state.

The door controller 54 estimates whether the multi-function toilet 14 is in a used state or an unused state based on the command immediately before being output. That is, the door controller 54 also functions as an estimation unit for estimating whether the multi-function toilet 14 is in a used state or an unused state. Specifically, the door controller 54 instructs the multi-function toilet 14 to shift to the standby state in which the multi-function toilet 14 is in an unused state among the plurality of standby states by the immediately preceding operation. If it is presumed that the toilet has moved to the unused state, and the operation immediately before is to instruct the multi-function toilet 14 to move to the used state among the plurality of standby states, the multi-function toilet is used. It is estimated that 14 has moved to the used state. For example, when the door controller 54 outputs a closing command from the closing sensor 40o in the second standby state, it is presumed that the multi-function toilet 14 has shifted to the unused state. Further, the door controller 54 estimates that the multi-functional toilet 14 is in an unused state even when the sliding door 20 is fully open for a predetermined time or longer. On the other hand, for example, when the door controller 54 outputs a closing command from the closing sensor 40i in the first standby state, the door controller 54 presumes that the multi-function toilet 14 has moved to the used state.

“To 1”, “to 2”, etc. described in Table 1 are numbers corresponding to the standby state of the door controller 54 when a command is output from the sensor described at the beginning of the line. It means to shift to the standby state. For example, when a command is output from the open sensor 38i while in the first standby state, the door controller 54 drives the sliding door 20 and shifts the standby state to the second standby state. Further, "invalid" described in Table 1 means that the output of the sensor described at the beginning of the line is invalidated in the standby state. For example, in the first standby state, the output of the closed sensor 40o is disabled.

Next, each standby state will be described in detail.

[1st standby state]
In the first standby state, the door controller 54 enables the outputs of the open sensors 38i and 38o and the closed sensors 40i. If the multi-function toilet 14 is in an unused state, there is no action that can be taken even if a command is output from the closed sensor 40o, so the door controller 54 invalidates the output of the closed sensor 40o. When a command is output from the open sensor 38i in the first standby state, the door controller 54 opens and drives the sliding door 20 to shift the standby state to the second standby state. Normally, there are no users in the multi-functional toilet 14 in the unused state, but there is a possibility that an error may occur in estimating the presence or absence of users. Therefore, in order to prevent the user from being confined, the door controller 54 opens and drives the sliding door 20 when a command is output from the open sensor 38i in the first standby state.

When an open command is output from the closing sensor 40i in the first standby state, the door controller 54 shifts the standby state to the fourth standby state while maintaining the sliding door 20 in the fully closed state. Since it is considered that there is a person in the multi-function toilet 14 that a command is output from the closed sensor 40i in the first standby state, the door controller 54 shifts the standby state to the fourth standby state, thereby shifting the sliding door. It is presumed that 20 is in a fully closed state and the multi-function toilet 14 is in a used state.

When an open command is output from the open sensor 38o in the first standby state, the door controller 54 drives the sliding door 20 toward the open state and shifts the standby state to the second standby state. As a scene where a command is output from the open sensor 38o in the first standby state, there is a scene in which the multi-function toilet 14 is in an unused state and an outdoor user is trying to use the multi-function toilet 14.

[Second standby state]
In the second standby state, the door controller 54 enables the outputs of the closed sensors 40i and 40o. Even if a command is output from the open sensors 38i and 38o in the open operation state, there is no action that can be taken, so the door controller 54 invalidates the output of the open sensors 38i and 38o.

When a closing command is output from the closing sensor 40i in the second standby state, the door controller 54 reversely drives the sliding door 20 to close the sliding door 20 and shifts the standby state to the fifth standby state. In the second standby state, the multi-function toilet 14 should be in an unused state, but when a command is output from the closing sensor 40i, the door controller 54 closes the sliding door and the multi-function toilet 14 is in the used state. I presume.

When a closing command is output from the closing sensor 40o in the second standby state, the door controller 54 closes the sliding door 20 and shifts the standby state to the third standby state. In the scene where the closing command is output to the closing sensor 40o in the second standby state, the user operates, for example, the opening sensor 38o in an attempt to use the multi-function toilet 14, but he / she quits using it in the middle and the closing sensor 40o. There is a scene where you operated.

[Third standby state]
In the third standby state, the door controller 54 enables the outputs of the open sensors 38i and 38o. If the multi-function toilet 14 is in the closed operation, there is no action that can be taken even if a command is output from the closed sensors 40i and 40o, so the door controller 54 invalidates the output of the closed sensors 40i and 40o. When the sliding door 20 is fully closed, the door controller 54 changes the standby state to the first standby state.

When an open command is output from the open sensor 38i in the third standby state, the door controller 54 reversely drives the sliding door 20 to open the sliding door 20. As a result, the sliding door 20 is in the open drive state while the multi-function toilet 14 remains unused. Further, when the open command is output from the open sensor 38o in the third standby state, the door controller 54 similarly drives the sliding door 20 in the reverse direction to open the sliding door 20. As a result, the sliding door 20 is in the open drive state while the multi-function toilet 14 remains unused.

[Fifth standby state]
In the fourth standby state, the door controller 54 enables the output of the open sensor 38i and invalidates the outputs of the open sensor 38o and the closed sensors 40i and 40o. This is because when the multi-function toilet 14 is in use and the sliding door 20 is in a fully closed state, it is necessary to make only the open sensor 38i in the room in operation.

When an open command is output from the open sensor 28i in the fourth standby state, the door controller 54 shifts the standby state to the second standby state.

[Fifth standby state]
In the fifth standby state, the door controller 54 enables the output of the open sensor 38i and disables the outputs of the open sensor 38o and the closed sensors 40i and 40o, as in the fourth standby state. The control when the open command is output from the open sensor 38i in the fifth standby state is the same as the control in the fourth standby state.

The door controller 54 sequentially changes its own standby state according to the state of the sliding door 20. Further, the door controller 54 also functions as a determination unit that indirectly determines the usage state of the multi-function toilet 14 according to the standby state.

The door controller 56 controls the motor 60 that is the drive source of the sliding door 20 based on the detection result of the protection sensor 48, the detection result of the auxiliary photoelectric sensor 42, and the drive command from the door controller 54. The door controller 56 receives outputs from the open / close sensors 38 and 40 via the door controller 54 and controls the electric lock 62 for locking the sliding door 20.

The door controller 54 and the door controller 56 together constitute a control unit of the automatic door device 10. The door controller 54 and the door controller 56 may be configured by the same hardware and software, or may be configured by different hardware and software. For example, when an automatic door device for the entrance / exit of a general building is diverted as an automatic door device for a multifunctional toilet, a door controller 54 and a command output unit 36 are added to the automatic door device for the entrance / exit of a general building. By doing so, the automatic door device 10 may be configured.

The notification unit 58 gives a predetermined notification to people around the automatic door device 10 including the user. As the notification unit 58, a speaker that aurally notifies a person, an electric bulletin board that visually notifies a person, and the like can be used. The notification output from the notification unit 58 is a notification selected by the door controller 54 according to the situation from a plurality of types of notifications determined in advance. Such notifications include a notification that the command content output from the open / close sensors 38 and 40 is unclear, a notification that the sliding door 20 is driven, guidance on how to operate the sliding door 20, and an abnormality has occurred in the room. There is a notice to that effect.

In the present embodiment, among the configurations shown in FIG. 3, the door controller 56, the door controller 54, the motor 60, the protection sensor 48, and the notification unit 58 are built in the transom 22. Each configuration does not need to be built in the transom 22, and various arrangements such as embedding the door controller 54 in the wall together with the command output unit 36 and fixing the notification unit 58 to the wall in the room are assumed. Will be done.

Next, the basic operation of the automatic door device 10 will be described.

When there are no people in the room of the multi-functional toilet 14, the automatic door device 10 keeps the sliding door 20 in a fully closed state. At this time, the standby state of the door controller 54 becomes the first standby state. When the user arrives at the outdoor side of the sliding door 20 and brings his / her hand close to the open sensor 38o of the outdoor command output unit 36o, the open sensor 38o outputs an ON signal to the door controller 54. When the door controller 54 receives the ON signal from the open sensor 38o, the door controller 54 supplies an open drive command to the door controller 56 to open the sliding door 20. The door controller 56 confirms that there is no person or object in the open detection area A4 by the open protection sensor 52, and drives the motor 60 to shift the sliding door 20 from the fully closed state to the fully open state in normal operation. At this time, the standby state of the door controller 54 becomes the second standby state. The door controller 56 continues to drive the sliding door 20 until the sliding door 20 is fully opened. As a result, the doorway 16 is fully opened and the user can enter the room. After entering the room, when the user brings his / her hand close to the closing sensor 40i of the indoor command output unit 36i and the door controller 54 receives the ON signal from the closing sensor 40i, the door controller 54 moves the sliding door 20 to the door controller 56. Supply a closed drive command to close. The door controller 56 confirms that there is no person or object in the indoor closed detection area A3 and the outdoor closed detection area A2 by the indoor closed protection sensor 50i and the outdoor closed protection sensor 50o, and the auxiliary photoelectric sensor 42. After confirming that there is no person or object in the auxiliary detection area A1, the motor 60 is driven to shift the sliding door 20 from the fully open state to the fully closed state by normal operation. At this time, the standby state of the door controller 54 becomes the fifth standby state. While the user is using the multi-functional toilet 14, the door controller 54 keeps the sliding door 20 in a fully closed state. At this time, the standby state of the door controller 54 becomes the fourth standby state. When the user brings his / her hand close to the open sensor 38i to get out of the multi-function toilet 14, the open sensor 38i outputs an ON signal to the door controller 54. When the door controller 54 receives the ON signal from the open sensor 38o, the door controller 54 supplies an open drive command to the door controller 56 to open the sliding door 20. The door controller 56 confirms that there is no person or object in the open detection area A4 by the open protection sensor 52, and drives the motor 60 to shift the sliding door 20 from the fully closed state to the fully open state in normal operation. At this time, the standby state of the door controller 54 becomes the second standby state.

[First operation method]
Next, the first operation method of the automatic door device 10 according to the embodiment will be described in detail. In the following, in order to explain the usefulness of the first operation method, the problems when the first operation method is not performed will be described first. At this time, for convenience of explanation, the automatic door device 10 described with reference to FIGS. 1 to 3 shall be used.

4 and 5 show a schematic view of the command output unit of the automatic door device. FIG. 4 shows an outdoor command output unit 36o as an example. As shown in FIG. 4, if the user can accurately reach only the detection area A5 of the open sensor 38o and output the open command only from the open sensor 38o, the sliding door 20 operates as intended by the user. However, it is difficult for the user to visually confirm the detection area A5 of the open sensor 38o. Also, in the case of the non-contact type command output unit, unlike the contact type command output unit, there is no feedback to the user such as resistance from the button, so it is tactilely recognized that the user has entered the detection area A5. It is also difficult. Further, as shown in FIG. 5, it may occur that the user's hand is in the detection area A5 and the user's arm is in the detection area A6 of the closed sensor 40o close to the open sensor 38o. It is difficult for the user to visually or tactilely recognize this. That is, when the non-contact type command output unit is applied to the automatic door device, it is assumed that the open sensor 38o and the closed sensor 40o are simultaneously operated on the outdoor command output unit 36o as shown in FIG. .. At this time, if the sliding door 20 is to be controlled so as to execute all the commands corresponding to the operation of the non-contact type command output unit, the sliding door 20 may continue to reciprocate between the open direction and the closed direction, or the direction not intended by the user. Phenomena such as the sliding door 20 moving occur. This is because in a standby state where the outputs of both sensors on either the indoor side or the outdoor side are valid, after the operation intended by the user is performed, the operation not intended by the user is performed. , It occurs when the standby state shifts by the first operation. This is because if the standby state is changed by the first operation, the later operation may become effective, and the sliding door 20 is not in the state intended by the user.

As an example, when the door controller 54 is in the first standby state and the sliding door 20 is in the non-driving state, the user tries to hold his / her hand over the open sensor 38o, and the user's hand and arm are in the open sensor 38o. It is assumed that both the detection area A5 and the detection area A6 of the closed sensor 40o are entered at the same time. The non-driving state means a state in which no driving force or braking force is applied to the sliding door 20 regardless of the current position of the sliding door 20. The non-driving state includes a state in which the automatic door device is in a standby state immediately after the power is turned on, a state in which the automatic door device is in a fully open state and waiting for an operation, and a state in which an electric lock is applied in a fully closed state. Since there is no error in the detection area A5 and the detection area A6 at distant positions and it is not actually possible that the hand and the arm enter at the same time, there is a certain error (for example, 0.5 ms) at the same time. It is assumed that the hand enters the detection area A5 and then the arm enters the detection area A6. In this case, since the hand is first detected in the detection area A5, the ON signal is supplied from the open sensor 38o to the door controller 54, and immediately after that, the ON signal is supplied from the closed sensor 40o to the door controller 54. Since the general automatic door device 10 is often configured to follow the latest operation (later operation), the general automatic door device 10 closes the sliding door 20 immediately after opening and driving the sliding door 20. After driving, the sliding door 20 is finally fully closed. Normally, since the user is not aware that he / she has put his / her arm in the detection area A6 of the closed sensor 40o, the user does not know the reason why the sliding door 20 does not open. This problem can occur in the first standby state in which the outputs of the two sensors (open sensor 38 and closed sensor 40) of the command output unit 36 are enabled.

FIG. 6 is a flow chart showing a series of processes of the door controller in the first operation method. In the following description, it is assumed that the user's hand or the like enters the detection area A5 of the open sensor 38i and then the user's hand or the like enters the detection area A6 of the closed sensor 40i.

When a series of processes are started, the door controller 54 receives the ON signal of one of the sensors in step S1. In this example, an ON signal is received from the closed sensor 40i.

In step S2, the door controller 54 determines whether or not the ON signal has already been supplied from the other sensor. In this example, the door controller 54 determines whether or not the ON signal is supplied from the open sensor 38i before the ON signal is supplied from the closed sensor 40i.

If it is determined in step S2 that the ON signal has already been supplied from the open sensor 38i (Yes in step S2), the door controller 54 has been supplied with the ON signal from the other sensor for 1 second or longer in step S3. Determine if it is before. In this example, it is determined whether the time when the ON signal is supplied from the open sensor 38i is 1 second or more before the time when the ON signal is supplied from the closed sensor 40i.

When the time when the ON signal is supplied from the open sensor 38i is 1 second or more before the time when the ON signal is supplied from the closed sensor 40i (Yes in step S3), the door controller 54 is the other in step S4. The sliding door 20 is driven according to the ON signal from the sensor. In this example, the door controller 54 closes and drives the sliding door 20 according to the closing command output from the closing sensor 40i.

When the time when the ON signal is supplied from the open sensor 38i is not more than 1 second before the time when the ON signal is supplied from the closed sensor 40i (No in step S3), the door controller 54 is set to 1 second in step S5. Since the ON signals are supplied from both sensors within the period, the two ON signals supplied are regarded as OFF signals, and the current state of the sliding door 20 is maintained. In this example, the door controller 54 treats the ON signal supplied from the open sensor 38i and the closed sensor 40i as an OFF signal. As a result, the sliding door 20 maintains the current state. Next, in step S6, the door controller 54 notifies a predetermined message via the notification unit 58. In this case, the door controller 54 does not drive the sliding door 20 because the user's intention cannot be grasped via the notification unit 58, and the hand is brought closer to the open sensor 38i or the closed sensor 40i again. Or, make an announcement to the user to pay attention to the direction. This encourages the user to perform the operation again.

If it is determined in step S2 that the ON signal is not supplied from the open sensor 38i at the present time (No in step S2), the door controller 54 receives the ON signal from one of the sensors in step S7 for 1 second or longer. Determine if it has passed. In this example, the door controller 54 determines whether or not one second or more has elapsed since the ON signal was received from the closing sensor 40i. When it is determined that the door controller 54 has not elapsed for 1 second or more (No in step S7), the door controller 54 repeats the processes after step S2. When it is determined that the door controller 54 has elapsed for 1 second or more (Yes in step S7), the door controller 54 controls the sliding door 20 according to the ON signal from one of the sensors in step S8.

As described above, according to the first operation method, when two commands are output almost simultaneously (within 1 second), the intention of the user is unknown, so at least the user should not perform an unintended operation. Ignore the two signals. This makes it possible to prevent the sliding door 20 from being driven in a direction not intended by the user.

As described above, according to the first operation method, when two different commands are output, it is possible to prevent the sliding door 20 from moving at least in a direction not intended by the user.

[Second operation method]
Next, the second operation method of the automatic door device 10 according to the embodiment will be described in detail. With reference to FIG. 5, when the door controller 54 is in the first standby state, the user tries to hold his / her hand over the open sensor 38o, and the user's hand and arm close the detection area A5 of the open sensor 38o. A case where both of the detection areas A6 of the sensor 40o are entered will be described. The user does not notice that the hand and arm are in the detection area A5 and the detection area A6, and does not move the hand and arm as they are. In this case, an ON signal is supplied from the effective open sensor 38o to the door controller 54. As a result, the door controller 54 shifts the standby state to the second standby state and drives the sliding door 20 to open. When the standby state shifts from the first standby state to the second standby state, the output of the closed sensor 40o, which was invalid in the first standby state, becomes valid, and the output of the open sensor 38o becomes invalid. When the output of the closed sensor 40o becomes valid, the closed sensor 40o supplies an ON signal to the door controller 54. This drives the sliding door to close. At the same time, the door controller 54 shifts the standby state to the fourth standby state. In the fourth standby state, the output of the open sensor 38o, which was disabled when the second standby state was entered, becomes valid again, and the output of the closed sensor 40o becomes invalid. When the output of the open sensor 38o becomes valid again, the open sensor 38o supplies an ON signal to the door controller 54. As a result, the sliding door 20 is driven to open again. As described above, in a specific case, an infinite loop may occur between the second standby state and the fourth standby state while the user touches the detection areas A5 and A6.

In the second operation method, the automatic door device 10 prevents the occurrence of the above-mentioned infinite loop by the following control. Briefly, in the second operation method, when both the open sensor 38o and the closed sensor 40o are operated while the sliding door 20 is being driven and two different commands are output, it is infinite by ignoring one command. Prevent loops.

FIG. 7 is a flow chart showing a series of processes of the door controller in the second operation method. In the following description, it is assumed that a command is output from the open sensor 38o in the third standby state and the standby state of the door controller 54 is in the second standby state.

In step S11, the door controller 54 determines whether or not the valid sensor signal has become an ON signal. In this example, it is determined whether or not the ON signal is supplied from the closed sensor 40o to the door controller 54 in the current second standby state. When the signal of the valid sensor is an ON signal (Yes in step S11), the door controller 54 drives the sliding door 20 according to the ON signal from the valid sensor in step S12. In this example, when the ON signal is supplied from the closing sensor 40o that is valid in the second standby state, the door controller 54 closes and drives the sliding door 20. At the same time, the door controller 54 shifts the standby state to the third standby state.

If it is determined in step S11 that the disabled sensor signal is ON (No in step S11), the door controller 54 in step S13 waits for the disabled sensor signal to be in the current standby state. Determine if it is in the ON state. That is, when it is determined that both the valid sensor and the invalid sensor signals are ON signals in the current second standby state (No in step S11), the door controller 54 determines that the invalid sensor is in step S13. Determines when the signal of is turned on. In this example, the door controller 54 is set to the ON state before the open sensor 38o, which is invalid in the second standby state, shifts to the second standby state (that is, when it is in the third standby state). 2 Determine whether the device has turned on after shifting to the standby state.

When the door controller 54 determines in step S13 that the signal of the valid sensor has been changed to the current standby mode and then turned on (Yes in step S13), the door controller 54 is in step S12 or later. Execute the process. In this example, assuming that the open sensor 38o that is invalid in the second standby state is turned on after shifting to the second standby state, the command from the originally invalid open sensor 38o is ignored in the second standby state. do. Therefore, the door controller 54 closes and drives the sliding door 20 according to a command from the closing sensor 40o effective in the second standby state, and shifts the standby state to the third standby state.

The door controller 54 may drive the sliding door 20 in the opposite direction to the direction in which it is currently being driven. Reverse driving the sliding door 20 means driving the sliding door 20 in the opening direction toward the fully open state in the closing direction, or driving the sliding door 20 in the closing direction toward the fully closed state in the opening direction. It means to drive to. For example, it is assumed that the user holds his / her hand over the invalid closed sensor 40o and the valid open sensor 38o in the third standby state and holds the position of the hand as it is. In this case, the door controller 54 opens and drives the sliding door 20 in response to the signal from the open sensor 38o becoming an ON signal, and shifts the standby state to the second standby state. During this period, if the user keeps holding the position of the hand, the signal from the closed sensor 40o that became effective when the user shifts to the second standby state becomes an ON signal. Further, the signal from the open sensor 38o, which became invalid when the second standby state is entered, also becomes an ON signal, but by performing the process of step S13, it is effective in the third standby state and the second standby state. The ON signal from the open sensor 38o that has become invalid in the state is regarded as an OFF signal. On the other hand, for example, in the third standby state, it is assumed that the user tries to open the sliding door 20 by holding his / her hand only over the open sensor 38o and immediately puts his / her hand out of the detection area A5. In this case, the door controller 54 opens and drives the sliding door 20 according to the command output from the open sensor 38o, and shifts to the second standby state. In that state, it is conceivable that the user rushes to close the sliding door 20 and puts his / her hand in the detection area A5 of the open sensor 38o and the detection area A6 of the closed sensor 40o. In this case, by performing the process of step S14, it is possible to distinguish whether the hand is not moved before or after the standby state shifts, or whether the user has performed the operation of reversing the sliding door 20 again. In addition, if the user hastily tries to drive the sliding door 20 in the opposite direction and puts his / her hand in both detection areas A5 and A6, the user considers that he / she intends to drive the sliding door 20 in the reverse direction and uses it. The sliding door 20 can be reversely driven according to the intention of the person.

On the other hand, when it is determined that the invalid sensor signal has not been turned on since it was in the current standby state (that is, it was in the ON state before it was in the current standby state) (No in step S13). In step S14, the door controller 54 treats the ON signal from the effective sensor as an OFF signal and processes it. In this example, the ON signal from the closed sensor 40o, which is valid in the second standby state, is regarded as the OFF signal. At this time, since the sliding door 20 is being driven open, the sliding door 20 continues to be driven open by regarding the ON signal from the closing sensor 40o as an OFF signal. That is, it can be said that in step S13, the door controller 54 determines whether or not the command that triggered the transition to the standby state continues to be output regardless of the user's intention even after the transition to the standby state. .. As a result, even if the user keeps his / her hand in the same position before and after the standby state shifts, it is possible to prevent the standby state from continuing to loop between the second standby state and the third standby state.

As described above, according to the second operation method, it is possible to prevent the standby state from continuing to loop due to the processing of step S11, step S12, step S14, and step S15.

Further, according to the second operation method, if the user touches the detection areas A5 and A6 of the effective sensor while the sliding door 20 is closed or open, the sliding door 20 can be reversely driven. In this case, even if the user's hand enters the detection areas A5 and A6 of the invalid sensor, the sliding door 20 can be reversely driven by determining the time when the invalid sensor is turned on in step S14.

It is also conceivable that the user will not reach out of the detection areas A5 and A6 even if the sliding door 20 starts reverse driving. However, even if the door controller 54 starts the series of processes shown in FIG. 7 in a state where the user has not touched the detection areas A5 and A6 even after the reverse drive, the process in step S14 causes the reverse drive to occur even before the reverse drive is performed. The sliding door 20 will not be driven based on the command that continues to be output. Therefore, after starting the reverse drive of the sliding door 20, the command that has been continuously output before the reverse drive of the sliding door 20 can be ignored. This makes it possible to prevent the sliding door 20 from being further reversely driven against the intention of the user.

It is also possible to combine the first operation method and the second operation method. FIG. 8 is a flow chart of a series of processes in which the first operation method and the second operation method are combined.

When a series of processes are started, in step S31, the door controller 54 determines whether or not both the closed sensor 40 and the open sensor 38 are in the valid state in the current standby state. Both of them are effective here means that the open sensor 38i and the closed sensor 40i are effective, or the open sensor 38o or the closed sensor 40o is effective in either the outer or inner command output unit 36. say. That is, it can be said that in step S31, the door controller 54 determines whether or not the current standby state is the first standby state.

If it is determined in step S31 that both the closed sensor 40 and the open sensor 38 are in the valid state in the current standby state (Yes in step S31), the door controller 54 in step S32 is in step S1 according to the first operation method. The process of S8 is executed. On the other hand, if it is determined in step S31 that both the closed sensor 40 and the open sensor 38 are not in the effective state in the current standby state (No in step S31), the door controller 54 is set to the second operation method in step S33. Therefore, the processes of steps S11 to S15 are executed.

In this way, the first operation method and the second operation method can be combined according to the current standby state.

As a modification of the first embodiment, the door controller 54 maintains the current state of the sliding door 20 when the detection areas A5 and A6 of the invalid sensor are touched, and to that effect via the notification unit 58. May be notified to the user. That is, the automatic door device 10 according to the modified example does not start driving the sliding door 20 or reversely drive the sliding door 20 when the user enters the detection areas A5 and A6 which are invalid in the current standby state. The door controller 54 has access only to the invalid sensor detection areas A5 and A6, and has access to both the invalid sensor detection areas A5 and A6 and the valid sensor detection areas A5 and A6. If so, it is determined that the detection areas A5 and A6 of the invalid sensor have been touched. In this case, the automatic door device 10 tells the user that at least the invalid detection areas A5 and A6 are in the hands, or the hands are separated from the detection areas A5 and A6 and the desired detection areas A5 and A6 are displayed again. Notify that you hold your hand. Even with such a configuration, it is possible to prevent the sliding door 20 from being driven in a direction not intended by the user when the non-contact type command output unit is applied to the automatic door device.

As a further modification, if the two detection areas A5 and A6 are accessible regardless of whether the detection areas A5 and A6 are valid or invalid, the door controller 54 utilizes that fact via the notification unit 58. You may notify the person. That is, when the hands are in the two detection areas A5 and A6, the door controller 54 always maintains the current state of the sliding door 20 regardless of the time when the hands are in the detection areas A5 and A6. Notify the user that the detection areas A5 and A6 have been touched. This configuration also prevents the sliding door 20 from being driven in a direction not intended by the user.

As a further modification, in the second operation method, after the signal of the effective sensor becomes an ON signal, the door controller 54 does not output a command from all the sensors including the effective sensor. The command from any sensor may be ignored. That is, when the two detection areas A5 and A6 are in the hands, the door controller shifts to the second standby state and the output of the closed sensor 40o becomes valid, and even if the output of the open sensor 38o becomes invalid. 54 does not close the sliding door 20 based on the ON signal of the effective closing sensor 40o until both the detection areas A5 and A6 are not detected, and after both the detection areas A5 and A6 are not detected. , The sliding door 20 is closed and driven when the ON signal of the effective closing sensor 40o is supplied. This configuration also prevents the sliding door 20 from being driven in a direction not intended by the user.

[Second Embodiment]
Next, the second embodiment will be described. FIG. 9 is a block diagram of the automatic door device according to the second embodiment. The automatic door device 100 according to the second embodiment includes a contact type command output unit in addition to the configuration of the automatic door device 10. Since the other configurations of the automatic door device 100 are the same as the configurations of the automatic door device 10, detailed description thereof will be omitted.

Specifically, the automatic door device 100 includes an open button 102o and a close button 104o on the outdoor side and an open button 102i and a close button 104i on the indoor side as contact-type command output units. Hereinafter, in the present specification, the open button 102o, the close button 104o, the indoor open button 102i, and the closed button 104i may be collectively referred to as "open / close buttons 102, 104". The open button 102o and the close button 104o are connected to the outdoor command output unit 36o, and when the open button 102o or the close button 104o is pressed, an open command or a close command corresponding to the button is supplied to the door controller 54. The open button 102i and the close button 104i are connected to the indoor command output unit 36i, and when the open button 102i or the close button 104i is pressed, an open command or a close command corresponding to the button is supplied to the door controller 54. The commands from the open button 102o, the close button 104o, the open button 102i, and the close button 104i are always in a valid state.

The automatic door device 100 controls the sliding door 20 by giving priority to the command output from the contact type command output unit with respect to the command output from the non-contact type command output unit. For example, suppose that the user presses the close button 104o while the user holds his hand over the open sensor 38o and the door controller 54 opens and drives the sliding door 20. In this case, the door controller 54 closes and drives the sliding door 20 according to a command output from the close button 104o regardless of the state of the sliding door 20 or the standby state. If a person or an object is detected in the outdoor closing detection area A2 or the indoor closing detection area A3 when the closing command is output to the closing button 104o, the door controller 54 stops the sliding door 20. May be good.

Once an open command or a close command is output to the open / close buttons 102 and 104, the automatic door device 100 invalidates the outputs of the open sensor 38 and the close sensor 40 until the sliding door 20 is fully closed or fully opened. When the user operates the open / close buttons 102 and 104, the user may not pay attention to the detection areas A5 and A6 of the open sensor 38 or the closed sensor 40. In this case, it is conceivable that the user unintentionally puts a hand or an object in the detection areas A5 and A6, whereby the sliding door 20 is driven in a direction not intended by the user. Therefore, when an open command or a close command is output as a result of operating the open / close buttons 102 and 104, the output of the open sensor 38 and the close sensor 40 is temporarily disabled, so that the user unknowingly opens the open sensor 38. It is possible to prevent the sliding door 20 from malfunctioning due to putting a hand or an object in the detection areas A5 and A6 of the closed sensor 40.

Once the open / close command is output to the open / close buttons 102 and 104, the automatic door device 100 outputs the outputs of the open sensor 38 and the close sensor 40 until it is estimated that the multi-function toilet 14 is in an unused state. It may be disabled. For example, suppose that as a result of the user operating the open sensor 38o, an open command is output to open the sliding door 20 to enter the multifunctional toilet 14, and then the close button 104i is pressed to close the sliding door 20. In this case, it is considered that the user tends to prefer the contact type open / close buttons 102 and 104 rather than the non-contact type open sensor 38 and the closed sensor 40. In this case, it is possible that the user does not pay attention to the existence of the detection areas A5 and A6 of the open sensor 38 and the closed sensor 40, and the user unintentionally puts his or her hand or an object in the detection areas A5 and A6. The sliding door 20 may be driven against the intention of the user. Therefore, the door controller 54 disables the outputs of the open sensor 38 and the closed sensor 40 until the multi-function toilet 14 is in an unused state, and the door controller 54 slides the door based only on the command from the open / close buttons 102 and 104. Drive 20. This reduces the possibility that the sliding door 20 will be driven against the intention of the user.

The automatic door device 100 may urge the user to operate the open / close sensor 38 or the close sensor 40 by pressing the open / close buttons 102 and 104 when the user cannot properly operate the open sensor 38 or the close sensor 40. In this case, the door controller 54 measures the elapsed time from the start of the operation of the open / close buttons 102 and 104 when the multi-function toilet 14 is in an unused state. The door controller 54 operates with the open / close buttons 102 and 104, for example, if the multi-function toilet 14 is in use and the sliding door 20 is not fully closed even after a predetermined time (for example, 1 minute) has elapsed. The door is notified via the notification unit 58.

As described above, the automatic door device 100 can also prevent the sliding door 20 from being driven in a direction not intended by the user.

[Third Embodiment]
Hereinafter, the third embodiment of the present invention will be described in detail. The automatic door device according to the third embodiment is realized by the same hardware as the automatic door device according to the second embodiment. Therefore, a detailed description will be given below with reference to FIGS. 9, 2, and 3. The automatic door device according to the third embodiment produces a remarkable effect by using a capacitance type sensor as the open sensor 38 and the closed sensor 40.

The automatic door device according to the third embodiment invalidates the output of the sensor predetermined according to the state of the sliding door 20. This prevents other operations from becoming impossible. Table 2 shows the relationship between the state of the sliding door 20 and the state (valid or invalid) of the output of the sensor.

In Table 2, "stopped" means that the sliding door 20 is stopped between the fully open state and the fully closed state. The sensors in Table 2 indicate only the open sensor 38i and the closed sensor 40i on the indoor side, the open sensor 38o and the closed sensor 40o on the outdoor side, or the open sensor 38 and the closed sensor 40 both indoors and outdoors. When the open / close buttons 102 and 104 are provided, it is assumed that the outputs of the open / close buttons 102 and 104 are always enabled. Therefore, regardless of the state of the sliding door 20, the command output as a result of operating the open / close buttons 102 and 104 is always valid, and the automatic door device drives the sliding door 20 based on the command output from the open / close buttons 102 and 104. Let me.

When the sliding door 20 is stopped for some reason, the door controller 54 enables the outputs of both the open sensor 38 and the closed sensor 40. As a result, the operator can operate the sliding door 20 by operating either the open sensor 38 or the closed sensor 40.

When a capacitance type sensor is used as the open sensor 38 and the closed sensor 40, when the sliding door 20 is stopped, control is performed based on a command from a sensor having a larger change in capacitance. You may.

When the sliding door 20 is in a fully closed state and is on standby, the output of the open sensor 38 is enabled and the output of the closed sensor 40 is disabled. When the sliding door 20 is in the fully open state and is on standby, the output of the open sensor 38 is invalidated and the output of the closed sensor 40 is enabled. That is, the output of the sensor used to shift the sliding door 20 to the current state is disabled.

In a general automatic door device, if the closing sensor continues to be operated while the sliding door is in the fully closed state, the door controller will not accept other operations. Therefore, for example, it is assumed that the sliding door 20 is in the fully closed state and the luggage is placed in the detection area of the closed sensor 40o on the outdoor side. In this case, since the closing command is continuously output from the closing sensor 40o, the door controller 54 does not open and control the sliding door 20 even if the user in the room operates the open sensor 38i. Such a problem is likely to occur when a non-contact sensor is used. On the other hand, if the output of the closed sensor 40o is disabled in the above case, the open sensor 38i outputs an open command when the user in the room operates the open sensor 38i, and the sliding door 20 can be opened.

When the capacitance type sensor is used as the open sensor 38 and the closed sensor 40, the amount of change in the capacitance is larger instead of disabling the output of the closed sensor 40 when the sliding door 20 is in the fully closed state. Control may be performed based on a command from the sensor. As a result, the sliding door 20 can be opened and controlled regardless of the state of the closed sensor 40o by bringing a hand closer to the open sensor 38i to increase the change in capacitance.

Returning to the explanation in Table 2, the output of the open sensor 38 is invalidated and the output of the closed sensor 40 is enabled during the open operation in which the sliding door 20 is shifting from the fully closed state to the fully open state. Further, during the closing operation in which the sliding door is in the fully open state to the fully closed state, the output of the open sensor 38 is enabled and the output of the closed sensor 40 is invalidated. That is, the output of the sensor for driving the sliding door 20 in the same direction as the driving direction is invalidated. As a result, for example, the operation of closing the sliding door 20 while the sliding door 20 is being driven to be opened can be performed more reliably.

To explain from another viewpoint, in the third embodiment, the operation state of the sensor used to shift the sliding door 20 to the current state or the sensor for driving the sliding door 20 in the same direction as the driving direction is set. Regardless, when the other sensor is operated, the sliding door 20 is driven according to the operation of the other sensor.

As described above, according to the third embodiment, by disabling the output of the sensor determined in advance according to the state of the sliding door 20, it is possible to facilitate the control according to the intention of the user.

The present disclosure is not limited to the above-described embodiment, and each configuration can be appropriately changed without departing from the spirit of the present disclosure.

Among the embodiments disclosed in the present specification, those composed of a plurality of objects may be integrated with the plurality of objects, and conversely, those composed of one object are divided into a plurality of objects. be able to.
