OPENING-CLOSING CONTROL SYSTEM AND OPENING-CLOSING CONTROL METHOD BACKGROUND OF THE INVENTION

Field of the Invention

[0001] The invention relates to an opening-closing control system and an

opening-closing control method which control an opening-closing device provided at an

opening part of a window or a door way of a structure skeleton including a building

such as a house, an apartment building, a factory, a warehouse, etc., and particularly

relates to an opening-closing control system and an opening-closing control method of

an opening-closing apparatus operated electrically in accordance with a control signal

from a single-point remote control device.

2. Description of Related Art

[0002] It is common to use electric shutters or electric doors electrically performing

respective operations of opening, closing, stopping, etc., in opening-closing devices of

overhead doors, shutters, doors, etc., provided at opening parts of structure skeletons

including buildings such as apartment buildings, factories, warehouses, etc. Such an

opening-closing device which electrically performs respective operations of opening,

closing, stopping, executes a predetermined operation in accordance with a control

signal from a wired or wireless three-point switch including three types of switches

(manipulators), i.e., opening, closing, and stopping, or a wired or wireless single-point

switch including one switch (manipulator). The opening-closing control system

SUMMARY OF THE INVENTION

[Problems to be Solved by the Invention]

[0004] Since the opening-closing control system described in Patent Document 1 is

configured to operate in correspondence with a manipulation instruction signal from a

three-point switch remote control device, the same manipulation as the three-point

switch remote control device can be realized by using a single-point switch remote

control device.

File: 111793auftruetranslation

However, in an opening-closing control system configured to operate in correspondence

with a manipulation instruction signal from a single-point switch remote control device,

even if a three-point switch remote control device is to be connected to operate the

opening-closing control system in accordance with the manipulation instruction signal

of the three-point switch remote control device, the operation of opening, closing, and

stopping corresponding to the manipulation instruction signal of the three-point switch

remote control device cannot be executed.

[0005] That is, in the case where an opening-closing control system supports a

single-point switch remote control device and a three-point switch remote control device,

the opening-closing control system can be connected with either of the remote control

devices and perform a predetermined operation without a problem. In addition, in the

case where an opening-closing control system supports a three-point switch remote

control device, even if a single-point switch remote control device is connected, a

predetermined operation can be performed according to the invention disclosed in

Reference Document 1. However, in the case where an opening-closing control system

only supports a single-point switch remote control device, even if a three-point switch

remote control device is connected, an operation corresponding to a manipulation

instruction signal corresponding to a switch manipulation cannot be executed.

[0006] The invention is made in view of the above issues and provides an

opening-closing control system and an opening-closing control method capable of

executing an operation corresponding to a manipulation of a three-point switch even if a

three-point switch remote control device is connected with an opening-closing control

system supporting only a single-point switch remote control device.

Means for solving problems]

[0007] According to the first characteristic of an opening-closing control system

according to the invention, the opening-closing control system includes: an

opening-closing body means, provided at an opening part; a sensing means, sensing an

object existing in a predetermined region of the opening part and outputting a sensing

signal; a single-point manipulator means, outputting a single-point signal in accordance

with a manipulation of a single-point switch; and a control means electrically

controlling an operation of the opening-closing body means in accordance with input of

the single-point signal and the sensing signal. In the opening-closing control system, a

three-point manipulator means outputting an open-close-stop manipulation signal in

accordance with a manipulation of a three-point switch, and an adapter means, based on

an opening/closing position and an operation state of the opening-closing body means at

a time point when the open-close-stop manipulation signal is input, outputting the

single-point signal and the sensing signal to the control means, so that the

opening-closing body means executes an operation corresponding to the manipulation

signal, are provided.

[0008] The opening-closing body means is configured by an overhead door or a

shutter curtain provided in the doorway part of a structure skeleton including a building

such as an apartment building, a factory, a warehouse, etc. In the vicinity of the

opening part, the sensing means configured by a light projector, a light receiver, etc.,

provided at positions separated by a predetermined distance is provided. The control

means electrically controls the respective operations of opening, closing, stopping, etc.,

of the opening-closing body means in accordance with input of the single-point signal

File: 111793auftruetranslation

output from the single-point manipulator means and input of the sensing signal from the

sensing means. Since the single-point signal is output at the time when the

single-point switch is operated, the control means cyclically controls the operation of the

opening-closing body means, such as open-stop-close-open-stop-close-..., in accordance

with the input of the single-point signal. Accordingly, even if the open-close-stop

manipulation signal corresponding to the manipulation of the three-point switch is

directly input to the control means controlling the operation of the opening-closing body

in accordance with input of the single-point signal, the control means does not operate

normally. Here, in the invention, the adapter means is provided. Based on the

opening/closing position and the operation state of the opening-closing body means at

the time point when the open-close-stop manipulation signal in accordance with the

manipulation of the three-point switch is input, the adapter means outputs the

single-point signal and the sensing signal to the control means, so that the

signal. Accordingly, even if the three-point switch remote control device is connected

to the control means supporting only the single-point switch remote control device, the

operation of the opening-closing body means corresponding to the manipulation of the

three-point switch can be executed.

[0009] Regarding the second characteristic of the opening-closing control system

according to the invention, in the opening-closing control system described according to

the first characteristic, at a time when the single-point signal is input when the

opening-closing body means is stopped, the control means performs a closing operation

on the opening-closing body means in a case where a stopped position of the

File: 111793auftruetranslation

opening-closing body means is at an opening limit position or an intermediate position,

and the control means performs an opening operation on the opening-closing body

means in a case where the stopped position is at a closing limit position, at a time when

the single-point signal is input when the opening-closing body means is in operation, the

opening operation of the opening-closing body means is stopped in a case of the

opening operation, the opening operation is started after the opening operation of the

opening-closing body means is stopped in a case of the closing operation, and at a time

when there is the input of the sensing signal when the opening-closing body means is in

operation, the opening operation is maintained in the case of the opening operation, the

opening operation is started after the opening-closing body means is stopped in the case

of the closing operation.

This relates to the operation of a general control means of cyclically controlling the

operation of the opening-closing body means, such as

open-stop-close-open-stop-close-..., in accordance with the input of the single-point

signal, maintaining the opening operation in the case where the sensing signal is input in

the opening operation, and executing the reverse opening operation in the case where

the sensing signal is input in the closing operation.

[0010] Regarding the third characteristic of the opening-closing control system

the second characteristic, the adapter means includes: a current detection means,

detecting a current supplied to the control means, outputting a detection state as ON in a

case where the current is detected and outputting the detection state as OFF in a case

where the current is not detected; and a lower limit position detection means, detecting

File: 111793auftruetranslation

that the opening-closing body means is at a lower limit position, outputting a detection

state as ON in a case where the opening-closing body means is at the lower limit

position, and outputting the detection state as OFF in a case where the opening-closing

body means is not at the lower limit position. At a time when the detection state of the

current detection means is OFF and the detection state of the lower limit position

detection means is OFF, the single-point signal is output to the control means in a case

where a closing manipulation signal is input from the three-point switch, at a time when

the detection state of the current detection means is ON and the detection state of the

lower limit position detection means is OFF, the sensing signal is output and then the

single-point signal is output to the control means in a case where a stop manipulation

signal is input from the three-point switch, at a time when the detection state of the

current detection means is ON and the detection state of the lower limit position

detection means is OFF, the sensing signal is output to the control means in a case

where an opening manipulation signal is input from the three-point switch, and at a time

when the detection state of the current detection means is OFF and the detection state of

the lower limit position detection means is ON, the single-point signal is output to the

control means in a case where an opening manipulation signal is input from the

three-point switch.

According to the characteristic, the current supplied to the control means is detected,

whether the opening-closing body means is in operation or stopped is determined based

on the detection state as ON and the detection state as OFF of the current, the

opening/closing position of the opening-closing body means is determined based on the

detection state as ON and the detection state as OFF of the lower limit position, and, at

File: 111793auftruetranslation

the time when each of the manipulation signals of opening, closing, stopping is input

from the three-point switch, the single-point signal and the sensing signal are output to

the control means, so that the opening-closing body means executes the operation

corresponding to the manipulation signal.

[0011] According to the first characteristic of an opening-closing control method of

the invention, the opening-closing control method controls an opening/closing operation

of an opening-closing body device. The opening-closing control system includes: an

the single-point signal and the sensing signal. The opening-closing control method

includes: in a case where an open-close-stop manipulation signal in accordance with a

manipulation of a three-point manipulator means comprising a three-point switch is

input, based on an opening/closing position and an operation state of the

opening-closing body means at a time point when the open-close-stop operation means

is input, outputting the single-point signal and the sensing signal to the control means so

that the opening-closing body means executes an operation corresponding to the

manipulation signal.

This corresponds to the first characteristic of the opening-closing control system.

[0012] Regarding the second characteristic of the opening-closing control method

according to the invention, in the opening-closing control method described according

File: 111793auftruetranslation

to the first characteristic, at a time when the single-point signal is input when the

on the opening-closing body means in a case where a stopped position of the

and the control means performs an opening operation on the opening-closing body

means in a case where the stopped position is at a closing limit position. At a time

when the single-point signal is input when the opening-closing body means is in

operation, the opening operation of the opening-closing body means is stopped in a case

of the opening operation, the opening operation is started after the opening operation of

the opening-closing body means is stopped in a case of the closing operation. At a

time when there is the input of the sensing signal when the opening-closing body means

is in operation, the opening operation is maintained in the case of the opening operation,

the opening operation is started after the opening-closing body means is stopped in the

case of the closing operation.

This corresponds to the second characteristic of the opening-closing control system.

[0013] Regarding the third characteristic of the opening-closing control method

according to the invention, the opening-closing control method described according to

the second characteristic includes: detecting a current supplied to the control means,

to the control means in a case where a closing manipulation signal is input from the

three-point switch; at a time when the detection state of the current is ON and the

detection state of the lower limit position is OFF, outputting the sensing signal and then

outputting the single-point signal to the control means in a case where a stop

manipulation signal is input from the three-point switch; at a time when the detection

DESCRIPTION OF THE EMBODIMENTS

[0016] Hereinafter, preferred embodiments of an opening-closing control system

according to the invention will be described with reference to the accompanying

drawings. In the embodiment, as an opening-closing body device controlled by the

File: 111793auftruetranslation

opening-closing control system, a shutter device controlled to vertically open or close,

with the top being an opening direction and the bottom being a close direction, is

described as an example.

[0017] FIG. 1 is a view illustrating an appearance of a shutter device in which an

control device is installed. FIG. 2 is a partial perspective view viewing the shutter

device of FIG. 1 from the front. FIG. 3 is a schematic diagram illustrating an

opening-closing control system of the shutter device of FIG. 1. The shutter device is

normally provided at the opening part of a structure, such as a building, and basically

configured by a shutter case 1, a shutter curtain 2, guide rails 3 and 4, a single-point

remote control switch 5, and photoelectric sensors 6 and 7.

[0018] The guide rails 3 and 4 are provided on two end sides of the opening part of

the building to come into contact with two ends of the shutter curtain 2, and are

configured by metal members having guide grooves whose sectional shape extending

from a lintel part to the floor surface is in a "2 " shape (substantially in a C shape or a U

shape with corners). The shutter curtain 2 is raised and lowered along the respective

guide grooves of the guide rails 3 and 4 to perform an opening or closing operation of

the opening part. Inside the shutter case 1, a winding shaft 11 is rotatably disposed,

and the shutter curtain 2 is wound and rewound around the winding shaft 11. In

addition, inside the shutter case 1, a motor 13 is provided, and the winding shaft 11 is

rotated by a rotational driving force of the motor 13 to control the opening/closing

operation of the shutter curtain 2.

[0019] As shown in FIG. 2, inside the shutter case 1, the winding shaft 11, a chain 12,

File: 111793auftruetranslation

the motor 13, a position detection device 14, and a shutter switching control device 15

are provided. The winding shaft 11 is provided to be rotatable in the shutter case 1 and

winds and rewinds the shutter curtain 2. The chain 12 links a driving sprocket

provided at the rotation axis of the motor 13 and a driven sprocket provided at the

rotation axis of the winding shaft 11. Accordingly, the rotational driving force of the

motor 13 is transmitted to the side of the winding shaft 11 via the chain 12. When the

motor 13 rotates, the winding shaft 11 rotates via the chain 12, so as to control the

opening/closing operation of the shutter curtain 2.

[0020] In the motor 13, the position detection device 14 for detecting a rotation

position thereof, i.e., the opening/closing position and the opening/closing state of the

shutter curtain 2 is provided. The position detection device 14 is configured by a

pulse-generating rotary encoder, etc. Since a pulse signal in accordance with the

rotation of the motor 13 is output to the shutter switching control device 15, the rotation

position of the motor 13, the opening/closing position or the operation state of a closing

side end of the shutter curtain 2 at the opening part can be computed by the shutter

switching control device 15 based on the pulse generation state.

[0021] The shutter switching control device 15 is configured by a microcomputer, and

is powered with electric power from a power source 16 via power lines 16a and 16b.

The shutter switching control device 15 controls the rotation of the motor 13 in

correspondence with a manipulation of a manipulation button on a single-point remote

control switch 5. The single-point remote control switch 5 outputs an ON/OFF signal

in accordance with the manipulation of the manipulation button to the shutter switching

control device 15. It may also be that a wired single-point switch, etc., is used to

File: 111793auftruetranslation

transmit a control signal to the shutter switching control device 15 and execute an

opening/closing operation.

[0022] The photoelectric sensors 6 and 7 are obstacle sensing devices used to confirm

a passing state of a human being, a vehicle, etc., and existence of an object etc., and are

provided on the left and right ends on the lower side of the opening part. In the

drawing, while the photoelectric sensors 6 and 7 are provided at predetermined positions

on either the front or the rear of the opening part, the photoelectric sensors may also be

provided on both the front and the rear of the opening part and/or the top of the opening

part. The photoelectric sensor 6 is configured by a columnar light projector support

member, and the photoelectric sensor 7 configured by a light receiver support member

of the same shape is provided on the opposite side. The photoelectric sensors 6 and 7

are provided to be separated from each other in a distance equal to a longitudinal

direction dimension of the seat plate of the shutter curtain 2 or the width dimension of

the opening part.

[0023] A light projector 6a including a light-emitting element which emits, by itself,

light such as infrared light is supported by the photoelectric sensor 6, for example. A

light receiver 7a including a light-receiving element which perceives light by itself is

supported by the photoelectric sensor 7. The light projector 6a of the photoelectric

sensor 6 and the light receiver 7a of the photoelectric sensor 7 are provided to face each

other and form a light path 8 of an object sensing light beam traveling along the seat

plate on a lower side position of the opening part. In the case where the photoelectric

sensors 6 and 7 sense a human being or an object (vehicle) on the light path 8, a sensing

signal thereof is transmitted to the shutter switching control device 15 by a switching

File: 111793auftruetranslation

mechanism of photoelectric sensor amplifiers 6b and 7b. In FIG. 1, the light path 8

schematically illustrates an object sensing region of the photoelectric sensors 6 and 7.

[0024] The shutter switching control device 15 controls an opening operation and/or a

closing operation of the shutter curtain 2 in accordance with whether a human being or

an object (vehicle) is present between the light projector 6a of the photoelectric sensor 6

and the light receiver 7a of the photoelectric sensor 7.

[0025] FIG. 4 is a flowchart illustrating an example of a process corresponding to a

single-point switch remote control device executed by the shutter switching control

device of FIG. 3.

In Step S41, whether there is an input of a single-point switch determined. In the case

where there is an input of the single-point switch (YES), the flow proceeds to Step S42,

and in the case where there is no input of the single-point switch (NO), the flow

proceeds to Step S50.

In Step S42, whether the shutter curtain 2 is currently stopped or in operation (NO) is

determined, in the case where the shutter curtain 2 is currently stopped (YES), the flow

proceeds to Step S43, and in the case where the shutter curtain 2 is currently in

operation (NO), the flow proceeds to Step S47.

[0026] In Step S43 and Step S44, since the shutter curtain 2 is determined as stopped

in the previous Step S42, at which position the shutter curtain 2 is currently stopped is

determined, and a process corresponding to each stopped position is executed.

In Step S43, whether the shutter curtain 2 is stopped at a fully open position (opening

limit) is determined. In the case where the shutter curtain 2 is stopped at the opening

limit (YES), the flow proceeds to Step S45, in the case where the shutter curtain 2 is

File: 111793auftruetranslation

stopped at a non-opening-limit position (NO), the flow proceeds to Step S44.

In Step S44, whether the shutter curtain 2 is stopped in the intermediate between the

fully open position and a fully close position is determined. In the case where the

shutter curtain 2 is stopped in the intermediate (YES), the flow proceeds to Step S45.

In the case where the shutter curtain 2 is not stopped in the intermediate (NO), the

shutter curtain 2 is determined as stopped at a closing limit, so the flow proceed to Step

S46.

In Step S45, since the shutter curtain 2 is determined as stopped at the opening limit in

Step S43 or determined as stopped in the intermediate in Step S44, a closing operating

is performed on the shutter curtain 2 and the flow returns.

In Step S46, since the shutter curtain 2 is determined as stopped at the closing limit in

Step S44, an opening operation is performed on the shutter curtain 2 and the flow

returns. Here, the movement of the shutter curtain 2 in the opening operation is set as

a forward direction movement, and the movement thereof in the closing operation is set

as a reverse direction movement.

[0027] In Step S47, the shutter curtain 2 is determined as not stopped in Step S42, that

is, the shutter curtain 2 is determined as in operation in Step S42. Therefore, whether

the operation is the opening operation or the closing operation (NO) is determined. In

the case of the opening operation (YES), the flow proceeds to Step S48, and in the case

of the closing operation, the flow proceeds to Step S49.

In Step S48, since the shutter curtain 2 is determined as in the opening operation in Step

S47, the operation of the shutter curtain 2 is stopped, and the flow returns.

In Step S49, since the shutter curtain 2 is determined as in the closing operation in Step

File: 111793auftruetranslation

S47, the closing operation of the shutter curtain 2 is stopped, then the opening operation

is started, that is, a reverse opening operation is executed, and the flow returns.

[0028] In Step S50, whether there is a photoelectric tube input is determined. In the

case where there is a photoelectric tube input (YES), the flow proceeds to Step S51. In

the case where there is no photoelectric tube input (NO), the flow returns.

In Step S51, whether the shutter curtain 2 is in operation or stopped (NO) is determined.

In the case where the shutter curtain 2 is in operation (YES), the flow proceeds to Step

S53. In the case where the shutter curtain 2 is stopped (NO), the flow returns.

In Step S52, since the shutter curtain 2 is determined as in operation in the previous Step

S51, whether the shutter curtain 2 is in the opening operation is determined. In the

case where the shutter curtain 2 is in the opening operation (YES), the flow returns. In

the case where the shutter curtain 2 is in the closing operation (NO), the flow proceeds

to Step S53.

In Step S53, since there is a photoelectric tube input in the closing operation, the closing

operation of the shutter curtain 2 is stopped, and then the opening operation is started,

that is, the reverse opening operation is executed, and the flow returns.

[0029] According to the above flowchart, in the case where the single-point switch is

manipulated when the shutter curtain 2 is stopped, according to Steps S42 to S44, the

closing operation is executed in the case where the stopped position is at the opening

limit or the intermediate position, and the opening operation is executed in the case

where the stopped position is at the closing limit. In addition, in the case where the

single-point switch is manipulated when the shutter curtain 2 is in operation, according

to Step S47, the opening operation is stopped when the shutter curtain 2 is in the

File: 111793auftruetranslation

opening operation, and the reverse opening operation is executed when the shutter

curtain 2 is in the closing operation. In addition, in the case where there is an

photoelectric tube input when the shutter curtain 2 is in operation, the opening operation

is maintained when the shutter curtain 2 is in the opening operation, and the reverse

opening operation is executed when the shutter curtain 2 is in the closing operation.

[0030] Even if a three-point switch remote control device is connected with a shutter

device in which the conventional opening-closing control system only supporting the

single-point switch remote control device described above is mounted, the desired

operation cannot be executed. Therefore, in the embodiment, for example, an external

controller adapter 20 is separately provided in the shutter switching control device 15,

so that the configuration of the shutter switching control device 15 supporting the

single-point switch remote control device is compatible by making no more than some

changes to the interface part between the shutter switching control device 15 and the

external controller adapter 20 (e.g., simple changes such as changes or exchanges of

terminals, or changes such as changes or addition of signal lines), instead of making

significantly changes such as changes to a substrate in which multiple components are

mounted or changes of multiple components, and the opening-closing control system

only supporting the single-point switch remote control device can be controlled by using

a three-point switch remote control device.

[0031] FIG. 5 is a diagram illustrating a specific example of a case in which an

external controller adapter is provided to the opening-closing control system of FIG. 3.

In FIG. 5, those having the same configurations with FIG. 3 are referred to by the same

reference symbols, and the descriptions thereof will be omitted.

File: 111793auftruetranslation

[0032] The external controller adapter 20 is configured by a wireless circuit 21, a

lower-limit limit switch 22, a single-point signal generating switch 23, a sensor signal

generating switch 24, and a current sensor 25.

The wireless circuit 21 is a control means which is wirelessly connected to a three-point

remote control switch 8 and a mobile communication terminal 9, receives manipulation

signals corresponding to operations of the three-point remote control switch 8 and an

opening button, a stop button, a closing button of the mobile communication terminal 9.

[0033] The wireless circuit 21 and the three-point remote control switch 8 are

connected at a predetermined frequency band (e.g., 426 [MHz]), and are respectively

connected via predetermined IDs.

In addition, as a connection in which the mobile communication terminal 9 is connected

with the wireless circuit 21, a general-purpose short-range wireless communication

interface (e.g., Wi-Fl, infrared communication, BlueTooth (trademark), etc.) hidden in

the mobile communication terminal 9 is adopted, the mobile communication terminal 9

is connected with the wireless circuit 21 via the communication interface, and the

mobile communication terminal 9 can be used as a remote control switch. The mobile

communication terminal 9 functions as a three-point remote control switch for

open-close-stop control by starting application software. For example, the mobile

communication terminal 9, such as a mobile phone, a personal handy-phone system

(PHS), a smartphone, a personal digital assistant (PDA), functions as a three-point

remote control switch by using the application software.

[0034] The lower-limit limit switch 22 is a switch (lower limit position detection

means) which detects that the shutter curtain 2 is fully closed, i.e., at the lower limit

File: 111793auftruetranslation

position, and uses the position detection device 14 provided in a decelerator of the

motor. In the case where the position detection device 14 cannot be used as the

lower-limit limit switch 22, a switch capable of detecting the lower limit position of the

shutter curtain 2 may also be provided separately. The lower-limit limit switch 22

outputs a signal of the lower limit detection state as ON in the case where the shutter

curtain 2 is fully closed, i.e., the shutter curtain 2 is at the lower limit position, and

outputs a signal of the lower limit detection state as OFF in the case where the shutter

curtain 2 is not at the lower limit position.

[0035] The single-point signal generating switch 23 outputs a single-point signal,

which is the same as the signal output in the case where the single-point remote control

switch 5 is manipulated, to the shutter switching control device 15.

In the case where the photoelectric sensors 6 and 7 sense a human being or an object

(vehicle) in the light path 8, the sensor signal generating switch 24 outputs a sensor

signal, which is the same as the sensing signal output by the switching mechanism of the

photoelectric sensor amplifiers 6b and 7b, to the shutter switching control device 15.

[0036] The current sensor 25 is configured as a current detection means which outputs,

as a signal in accordance with the current value supplied to the shutter switching control

device 15 from the power source 16, a signal of the current detection state as ON in the

case where a current is detected and outputs a signal of the current detection state as

OFF in the case where a current is not detected, such as a current detection means

configured by using, for example, a magnetic sensor (Hall element), or other means

capable of detecting a current.

[0037] In the embodiment, the case where the wireless circuit 21 operates the

File: 111793auftruetranslation

single-point signal generating switch 23 and the sensor signal generating switch 24 to

output the single-point signal and the sensor signal to the shutter switching control

device 15 based on the manipulation signals from the three-point remote control switch

8 and the mobile communication terminal 9, the signal of the lower limit detection state

as ON/OFF from the lower-limit limit switch 22, and the signal of the current detection

state as ON/OFF from the current sensor 25 is described. A separate control circuit

other than the wireless circuit 21 may also be provided.

[0038] FIG. 6 is a flowchart illustrating an example of a process by the three-point

switch remote control device executed by the external controller adapter of FIG. 5.

In Step S61, whether the manipulation signal from the three-point switch is a stop

manipulation signal is determined. In the case where the manipulation signal from the

three-point switch is a stop manipulation signal (YES), the flow proceeds to Step S62.

In the case where the manipulation signal from the three-point switch is not a stop

manipulation signal (NO), the flow proceeds to Step S64.

[0039] In Step S62, whether the current detection state of the current sensor 25 is ON

(current detection as ON) and the shutter curtain 2 is not at the lower limit position, that

is, the lower limit detection state of the lower-limit limit switch 22 is OFF (lower-limit

limit as OFF) are determined, in the case where the determination result is YES, the

flow proceeds to Step S63, and in the case where the determination result is NO, the

flow returns.

[0040] In Step S63, the sensor signal is output to the shutter switching control device

15 and then the single-point signal is output. That is, with the current detection state of

the current sensor 25 being ON (current detection as ON) and the lower limit detection

File: 111793auftruetranslation

state being OFF (lower-limit limit as OFF), the shutter curtain 2 is not at the lower limit

position and is in the opening operation or the closing operation, so the external

controller adapter 20 outputs the sensor signal to the shutter switching control device 15.

Accordingly, through the determinations in Step S41, Step S50, and Step S51 of FIG. 4,

the determination of Step S52 is performed, the opening operation continues in the case

where the shutter curtain 2 is in the opening operation, and the reverse opening

operation is executed in the case where the shutter curtain 2 is in the closing operation.

That is, the shutter curtain 2 executes the opening operation. Immediately thereafter,

the external controller adapter 20 outputs the single-point signal to the shutter switching

control device 15. Accordingly, through the determinations in Step S41, Step S42, and

Step S47 of FIG. 4, the stop process of Step S48 is executed, and the shutter curtain 2 is

stopped. Accordingly, a stop operation of the shutter curtain 2 is executed in

correspondence with the stop manipulation signal from the three-point switch.

[0041] In Step S64, whether the manipulation signal from the three-point switch is an

opening manipulation signal is determined. In the case where the manipulation signal

from the three-point switch is an opening manipulation signal (YES), the flow proceeds

to Step S65. In the case where the manipulation signal from the three-point switch is

not an opening manipulation signal (NO), the flow proceeds to Step S69.

In Step S65, whether the current detection state of the current sensor 25 is ON (current

detection as ON) and the shutter curtain 2 is not at the lower limit position, that is, the

lower limit detection state of the lower-limit limit switch 22 is OFF (lower-limit limit as

OFF) are determined, in the case where the determination result is YES, the flow

proceeds to Step S66, and in the case where the determination result is NO, the flow

File: 111793auftruetranslation

proceeds to Step S67.

[0042] In Step S66, the sensor signal is output to the shutter switching control device

15. That is, with the current detection state of the current sensor 25 being ON (current

detection as ON) and the lower limit detection state of the lower-limit limit switch 22

being OFF (lower-limit limit as OFF), the shutter curtain 2 is not at the lower limit

Accordingly, an opening operation of the shutter curtain 2 is executed in correspondence

with the opening manipulation signal from the three-point switch.

[0043] In Step S67, whether the current detection state of the current sensor 25 is OFF

(current detection as OFF) and the shutter curtain 2 is at the lower limit position, that is,

the lower limit detection state of the lower-limit limit switch 22 is ON (lower-limit limit

as ON) are determined, in the case where the determination result is YES, the flow

proceeds to Step S68, and in the case where the determination result is NO, the flow

returns.

[0044] In Step S68, the single-point signal is output to the shutter switching control

device 15. That is, with the current detection state of the current sensor 25 being OFF

(current detection as OFF) and the lower limit position state of the lower-limit limit

switch 22 being ON (lower-limit limit as ON), the shutter curtain 2 is stopped at the

File: 111793auftruetranslation

lower limit position, so the external controller adapter 20 outputs the single-point signal

to the shutter switching control device 15. Accordingly, through the determinations in

Steps S41 to S44 of FIG. 4, the opening operation of Step S46 is executed.

Accordingly, the opening operation of the shutter curtain 2 is executed in

correspondence with the opening manipulation signal from the three-point switch.

[0045] In Step S69, whether the manipulation signal from the three-point switch is a

closing manipulation signal is determined. In the case where the manipulation signal

from the three-point switch is a closing manipulation signal (YES), the flow proceeds to

Step S70. In the case where the manipulation signal from the three-point switch is not

a closing manipulation signal (NO), the flow returns.

In Step S70, whether the current detection state of the current sensor 25 is OFF (current

detection as OFF) and the shutter curtain 2 is not at the lower limit position, that is, the

proceeds to Step S71, and in the case where the determination result is NO, the flow

returns.

[0046] In Step S71, the single-point signal is output to the shutter switching control

switch 22 being OFF (lower-limit limit as OFF), the shutter current 2 is stopped at the

upper limit position (opening limit) or stopped in the intermediate (in other words,

stopped at a position between the opening limit and the closing limit), so the external

controller adapter 20 outputs the single-point signal to the shutter switching control

File: 111793auftruetranslation

device 15. Accordingly, through the determinations in Steps S41 to S44 of FIG. 4, the

closing operation of Step S45 is executed. Accordingly, a closing operation of the

shutter curtain 2 is executed in correspondence with the closing manipulation signal

from the three-point switch.

[0047] FIG. 7 is a diagram showing a list with correspondence relationships between

the respective manipulations of the single-point switch remote control device of FIG. 4

and the three-point switch remote control device of FIG. 6 and the operations of the

shutter curtain. In the list of FIG. 7, the items in the horizontal direction include five

items, i.e., "shutter state", "single-point input", "current detection state", "lower limit

position state", and "three-point input".

[0048] Regarding the items "shutter state" and "single-point input", the table shows

the operation executed in the case where the single-point switch remote control device is

manipulated when the shutter in the state shown in the item "shutter state".

In the case where the single-point switch is manipulated at the time when the shutter

state indicates "stopped in intermediate" or "stopped at opening limit", as shown in the

item "single-point input", the closing operation of Step S45 of FIG. 4 is executed. At

the time when the shutter state indicates "in opening operation", the stop operation of

Step S48 of FIG. 4 is executed. At the time when the shutter state indicates "in closing

operation", the reverse opening operation of Step S49 of FIG. 4 is executed. At the

time when the shutter state indicates "stopped at closing limit", the closing operation of

Step S45 of FIG. 4 is executed. At the time when the shutter state indicates

"immediately after opening operation from being stopped at closing limit", the stop

operation of Step S48 of FIG. 4 is executed. At the time when the shutter state

File: 111793auftruetranslation

indicates "immediately after being stopped at closing limit from closing operation", the

reverse opening operation of Step S49 of FIG. 4 is executed.

[0049] Regarding the items "current detection" and "lower-limit limit", the table

shows ON/OFF of the current detection state of the current sensor 25 and ON/OFF of

the lower limit position state of the lower-limit limit switch 22 of the external controller

adapter 20 in the case where there is the shutter in the state shown in the item "shutter

state".

[0050] At the time when the shutter state indicates "stopped in intermediate" or

"stopped at opening limit", the current detection state and the lower limit position state

are both OFF. At the time when the shutter state indicates "in opening operation" or

"in closing operation", the current detection state is ON, and the lower limit position

state is OFF. At the time when the shutter state indicates "stopped at closing limit", the

current detection state is OFF, and the lower limit position state is ON. At the time

when the shutter state indicates "immediately after opening operation from being

stopped at closing limit" or "immediately after being stopped at closing limit from

closing operation", the current detection state and the lower limit position state are both

ON.

[0051] Accordingly, at the time when the current detection state and the lower limit

position state are both OFF, the external controller adapter 20 outputs the manipulation

signal of the single-point switch to the shutter switching control device 15 in the case

where the closing manipulation signal is received from the three-point switch.

Accordingly, the closing operation of Step S45 of FIG. 4 is executed.

[0052] At the time when the current detection state is ON and the lower limit position

File: 111793auftruetranslation

state is OFF, in the case where the opening manipulation signal is received from the

three-point switch, the external controller adapter 20 outputs the sensor signal to the

shutter switching control device 15. Accordingly, the reverse opening operation of

Step S53 of FIG. 4 is executed.

[0053] At the time when the current detection state is ON and the lower limit position

state is OFF, in the case where the stop manipulation signal is received from the

shutter switching control device 15 and executes the reverse opening operation of Step

S53 of FIG. 4, and, immediately thereafter, outputs the single-point signal to the shutter

switching control device 15. Accordingly, the stop operation of Step S48 is executed.

[0054] At the time when the current detection state is OFF and the lower limit

position state is ON, in the case where the opening manipulation signal is received from

the three-point switch, the external controller adapter 20 outputs the single-point signal

to the shutter switching control device 15. Accordingly, the opening operation of Step

S46 is executed.

[0055] Although in the flowchart of FIG. 6, a determination is not performed at the

time when the current detection state and the lower limit position state are both ON, in

such case, "NO" is determined in Step S62, Step S65, Step S67, and Step S70, and the

flow directly returns without executing any process. Therefore, in the table, it is

described as "invalid". Except for the above, "invalid" means that the flow returns

without performing any process.

[0056] In the above embodiment, a shutter curtain which is extended in an

up-and-down manner is described as an example. However, a shutter-like

File: 111793auftruetranslation

opening-closing member which is extended by being pulled laterally or a shutter curtain

which is extended horizontally is also applicable. In addition, as an opening-closing

body device such as a shutter device, an overdoor device, a window shutter device, a

blind device, a roll screen device, a hanging curtain device, a sliding door device, a

moving partition device, an awning device, a waterproof plate device, a gate door device,

a gate device is also applicable.

[0057] Although in the above embodiment, the case where the external controller

adapter 20 is wirelessly connected to the three-point remote control switch 8 and the

mobile communication terminal 9 via the wireless circuit 21 is described, the external

controller adapter 20 may also be connected with the three-point remote control switch

in a wired manner. In addition, by being inserted into a USB or a power socket of a

vehicle, an automatic opening/closing remote controller, etc., functioning as a

three-point switch remote control device can be connected via a wireless circuit. These

may also be connected via a control circuit such as a wired control circuit different from

the wireless circuit 21 provided in the external controller adapter 20.

[0058] In the case where the mobile communication terminal 9 is wirelessly

connected with the wireless circuit 21, since the shutter state can be recognized based on

the current detection state and the lower limit position state, by answering (or feeding

back) the signal relating to the shutter state to the mobile communication terminal 9 via

the wireless circuit 21, the shutter state can be recognizable on a display screen of the

mobile communication terminal 9. For example, in the case where the current

detection state and the lower limit position state are both OFF, since the shutter state is

"stopped in intermediate" or "stopped at opening limit", the shutter state is displayed on

File: 111793auftruetranslation

the mobile communication terminal 9. In the case where the closing manipulation

button is manipulated when "stopped" is displayed, since the closing operation is started,

the shutter state as being in the closing operation is displayed on the mobile

communication terminal 9. In the case where the current detection state is ON and the

lower limit position state is OFF, since the shutter state is in the opening operation or

the closing operation, the shutter state is displayed on the mobile communication

terminal 9. In the case where the stop button is manipulated in the opening operation

or the closing operation, stop is executed, so the shutter state as "stopped" is displayed

on the mobile communication terminal 9. In addition, in the case where the opening

button is manipulated in the opening operation or the closing operation, the reverse

opening operation is executed, so the shutter state as being in the opening operation is

displayed on the mobile communication terminal 9. In the case where the current

detection state is OFF and the lower limit position state is ON, since the shutter state

corresponds to "stopped at closing limit", the shutter state is displayed on the mobile

communication terminal 9. In the case where the opening button is manipulated when

"stopped at closing limit" is displayed, since the opening operation is executed, the

shutter state as being in the opening operation is displayed on the mobile

communication terminal 9. In the case where the current detection state and the lower

limit position state are both ON, due to an extremely short time in "immediately after

opening operation from being stopped at closing limit" or "immediately after being

stopped at closing limit from closing operation", the shutter state is not displayed on the

mobile communication terminal 9 at this time.

[0059] In the above embodiment, although the lower-limit switch 22 or the current

File: 111793auftruetranslation

sensor 25 is used as a means of obtaining the opening/closing position or the operation

state of the shutter curtain, sensors determining the height position (opening/closing

position) from the shutter lower end or the operation state other than the above, such as

a combination of a displacement sensor and an acceleration sensor, may also be used to

transmit signals from such sensors to the wireless circuit 21. In addition, as a sensor

capable of detecting the height position (opening/closing position) or from the lower end

of an overhead door, etc., or the operation state, the Garage Door Sensor manufactured

by STEEL-LINE may be used.

In addition, it may also be that a GPS is attached to the tip part of the shutter curtain and

the height position (opening/closing position) from the shutter lower end or the

operation state is determined based on the position information of the GPS.
