Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing system, for example, a shutter, a door, a window, an overhead door, a gate, a gate (gate for a parking lot, etc.), a roll screen (for example, a blackout curtain), a blind, an awning device, and the like. It can be applied to a remote control system (remote control system) and the like.

The present invention also relates to a switchgear as a component of such a switchgear system.

2. Description of the Related Art As a composite shutter system composed of two shutter devices each of which can operate independently, one shutter device is open when the other shutter device is open for the purpose of blocking the outside air. Some have an interlock function that limits the opening of the shutter device.

In this interlock function, one shutter device is in an open state (it is not necessary to be in a completely closed state).
In the case of, the other shutter device has to maintain a completely closed state (a state in which the opening is completely closed),
The degree of freedom of the shutter operation is highest when the two shutter devices are both completely closed, and both shutter devices can perform the opening operation according to the received shutter operation designating signal.

However, when the two shutter devices simultaneously perform the opening operation, it becomes impossible to block the outside air, and therefore the outside air is kept blocked by the following simple one-way communication.

That is, when one of the two shutter devices in the completely closed state performs the opening operation, a predetermined opening operation notification signal is transmitted to the other shutter device so that the opening operation is performed. Notify the occurrence. The other shutter device that receives the opening operation notification signal maintains the completely closed state even if it receives a shutter operation designating signal for instructing the opening operation to itself after this reception, so the outside air is blocked. Can continue.

On the other hand, when the shutter device in the open state is completely closed, the closed state notification signal can be transmitted to the other shutter device so that the other shutter device can perform the opening operation. Inform you that you are in good condition. The other shutter device, which has been kept in the completely closed state until then, receives the shutter state notification signal and then receives the shutter operation designating signal for instructing the opening operation, and immediately starts the opening operation accordingly. It is possible to

[0008]

However, when the shutter device is a seat shutter device having a shutter curtain made of a light and mechanically fragile material, when the shutter device is completely closed, the lower end portion of the shutter curtain is the floor surface. If the impact on the vehicle is too strong, the shutter curtain may be damaged due to the impact. Therefore, at a predetermined position (deceleration start position) higher than the floor surface where the lower end reaches when fully closed. Thus, there is a case where the power supply to the motor that is rotating the output shaft for closing is stopped.

After the power supply is stopped, the shutter curtain moves by inertia while resisting friction with the guide rail, wind pressure, etc., and gradually decelerates to the floor surface or the like under a relatively weak impact. To reach.

If both of the above-mentioned two shutter devices are sheet shutter devices, both of the two shutter devices start deceleration from the deceleration start position when performing complete closing, so that the above-mentioned closed state notification signal also
When it reaches the deceleration start position, it is transmitted to the other shutter device.

In this case, if the shutter device receiving the closed state notification signal receives a shutter operation designating signal instructing the opening operation immediately after that, the opening operation is immediately performed according to the shutter operation designating signal. Although it is time (for example, about 0.3 seconds), a situation may occur in which both shutter devices are not in the completely closed state, which may reduce the effect of blocking the outside air, which may reduce reliability and interlock. There is a possibility that the purpose of the function cannot be sufficiently achieved.

Further, a user or the like who has transmitted a shutter operation designating signal designating an opening operation using a remote control transmitter or the like may see a situation in which the two shutter devices are not completely closed. There is concern about whether the lock function is working properly, and there is a concern that the reliability will drop and it will not be possible to use the compound shutter system with peace of mind.

The above problems are caused by sheet shutters,
Not only for shutters such as garage shutters and window shutters, but also for other opening and closing systems such as doors, windows and overhead doors.

An object of the present invention is to provide an opening / closing system and an opening / closing device with high reliability and reliability.

[0015]

In order to solve such a problem, in the first invention, the operating states of a plurality of opening / closing devices which operate the opening / closing body basically independently in response to the supplied operation instruction signal. In the opening and closing system having a predetermined interlocking relationship, each of the opening and closing devices includes operation control means for controlling the operation of the opening and closing body, and the operation control means is a limit of the operation of the opening and closing body. The opening / closing body is caused to operate from the pre-limit position before reaching the limit position by inertia, and while the opening / closing body of the own opening / closing device is inertially operated, the opening / closing body of another opening / closing device is operated according to the interlocking relationship. It is characterized in that a predetermined operation restricted by the above is not performed.

According to the second aspect of the invention, in the opening / closing device for operating the opening / closing body according to the supplied operation instruction signal,
(1) Inter-switching device communication means for performing communication with another switchgear having a predetermined interlocking relationship with its own switchgear,
(2) An operation control unit that controls the operation of the opening / closing body, and (3) the operation control unit opens / closes the limit opening position before reaching a limit position that is the limit of the operation of the opening / closing body. Is operated by inertia, and while the opening / closing body is operating by inertia, the opening / closing body of the other opening / closing device is not allowed to perform a predetermined operation limited according to the interlocking relationship.

[0017]

BEST MODE FOR CARRYING OUT THE INVENTION (A) Embodiment Hereinafter, an opening / closing system and an opening / closing device according to the present invention will be described.
The embodiment will be described by taking as an example the case where the invention is applied to a composite shutter system having one sheet shutter (remote operation system (remote control system)).

Generally, the remote control system includes a wired remote control system, the wireless remote control system, and a mixing system in which these are mixed.

Here, the wired remote control system is a remote control system including a shutter system as a component, and performs a shutter operation by wired communication.

Generally, the wireless remote control system is advantageous in that the shutter operation can be performed from an unspecified position distant from a long distance and the usability is good, and the wireless remote control system is advantageous in terms of communication reliability and always in a specified position. The wired remote control system is suitable when the user wants to specify the shutter operation.

Further, if the same shutter system can be controlled by wire or wirelessly, there is a great deal of flexibility, and either method can be adopted depending on the convenience of the user. Therefore, an actual remote control system is often a mixed system in which the features of the wireless remote control system and the wired remote control system are mixed. However, in the present embodiment, in order to simplify the description, it is assumed that the composite shutter system is a wireless remote control system including a separate remote control receiver that can instruct a shutter operation using different remote control transmitters. To do.

(A-1) Configuration of Embodiment FIG. 2 shows an example of the overall configuration of the composite shutter system 10 of this embodiment.

In FIG. 2, the composite shutter system 10 includes remote control receivers 11A and 11B which will be described later.
The remote control transmitters 12A and 12B, the sheet shutter devices 14A and 14B, the buffer space 13, and the transmission path 15 are provided.

Of these, the buffer space 13 is a buffer space that can be covered with the wall surface, the floor surface, and the shutter curtains 14AC and 14BC of the two sheet shutter devices 14A and 14B. In the illustrated example, buffer space 1
The shape of 3 is a rectangular parallelepiped, but this does not need to be limited to a rectangular parallelepiped. For example, there may be a configuration in which one side cannot see through because it is bent in an “L” shape (for example, the shutter curtain 14BC of the shutter device 14B from the user U1 side to the user U2 side cannot see through).

There may be various purposes for providing such a buffer space 13. For example, shut off the outside air,
This may be the case when achieving purposes such as dustproofing, insect control, cold insulation, and heat retention. If the SA side on which the user U1 is located is inside (such as a factory), the SB side on which the user U2 is located is outside (such as a factory). When the required accuracy of dust proof, insect repellency, cold insulation, heat retention, etc. is high, a shutter having high airtightness, an opening / closing door, or the like may be used instead of the sheet shutter devices 14A and 14B.

The sheet shutter devices 14A and 14B are
Unlike a slat shutter having a large number of slats made of metal such as iron, the shutter is mainly composed of sheet-like curtains 14AC, 14BC made of a light material such as a synthetic resin such as vinyl chloride or polyester or a cloth cloth. . In the sheet shutter devices 14A and 14B, since the material of the shutter curtain is lightweight, the moment of inertia that can act on the output shafts of the motors MA and MB that supply the torque that serves as the power source for the opening and closing operations of the shutter devices 14A and 14B. A small and high-speed opening / closing operation can be easily realized. As an example, the motor M
A and MB may be AC servo motors, for example, and may rotate at a speed of about 3000 revolutions per second when the sheet shutter device 14A is caused to perform an opening operation (or a closing operation).

The two shutter devices 14A and 14B arranged at both ends of the buffer space 13 include the motors MA and MB in addition to the illustrated shutter curtains 14AC and 14BC.
The shutter curtain 14A according to the rotation of the output shaft of B
This is a part for performing opening / closing operations of C and 14BC.

The rotation of the output shafts of the motors MA and MB is
It is controlled by a motor control unit 64 (see FIG. 1) built in the remote control receivers 11A and 11B.

The user U1 who performs the opening / closing operation of the shutter device 14A can perform a desired shutter operation by operating the remote control transmitter 12A carried by the user. For this operation, the shutter curtain 1
4AC is wound up and the lower end portion 14AD of the curtain is indicated by the arrow D2.
Opening operation to move in the direction, unfold the rolled shutter curtain 14AC and move the curtain lower end 14AD to the arrow D
In addition to the closing operation to move in one direction, the lower end portion 14 during movement
A stop operation for stopping AD at that position is also included.
The relationship between the user U2, the remote control transmitter 12B thereof, and the shutter device 14B is similar to this.

However, the remote control transmitter that can instruct the shutter device 14A to perform the shutter operation is not limited to the remote control transmitter 12A, and a plurality of remote control transmitters may be used as necessary. The same applies to the shutter device 14B and the remote control transmitter 12B.

The remote control transmitter 12A has an appearance as shown in FIG. 3, for example. Remote control transmitter 12
The appearance and size of B may be the same as in FIG.

The remote control transmitter 12A is a palm-sized wireless transmitter that is highly portable and compact enough to fit in the palm of the user U1. Since all the functions are accommodated in the compact main body 12AD as described above, it is necessary to save the functions of the remote control transmitter 12A to the utmost limit.

In FIG. 3, the main body 12AD of the remote control transmitter 12A has a PBS (push
Button-switch type three operation switches 51-5
Equipped with 3. These operation switches 51 to 53 are shutter operation switches that can perform the desired shutter operation.

In the present embodiment, of the shutter operation switches 51 to 53, the shutter operation switch 51.
Is an opening operation switch for performing an opening operation of the shutter 14A, a shutter operation switch 52 is a closing operation switch for performing a closing operation of the shutter 14A, and a shutter operation switch 53 is an opening operation or a closing operation of the shutter 14A. Shall be a stop switch for stopping at any timing.

However, it is possible to instruct a wider variety of shutter operations by changing the combination of the operation switches that are pressed down or by changing the method of pressing. For example, by pressing the closing operation switch 52 and the stop switch 53 simultaneously for a short time (for example, within 3 seconds), it is possible to instruct opening operation and closing operation (that is, intermediate stop operation) up to a predetermined intermediate position (intermediate stop position). It can also be configured. The state where the curtain lower end portion 14AD is moved to the limit in the direction of the arrow D1 shown in FIG. 2 is the completely closed state, and conversely, the state where the curtain lower end portion 14AD is moved to the limit to the direction of the arrow D2 is the completely open state, and the curtain lower end portion 14AD When the position is in the middle of the two, it is the intermediate position.

Further, if necessary, it is possible to perform a more complicated operation by combining the operations of these operation switches 51 to 53 according to a combination other than 52 and 53. As an example, when the shutter curtain portion of the shutter device 14A is a slat shutter or the like, ventilation operation (air inside and outside the shutter may flow by controlling the size of the opening provided between the adjacent slats). An operation such as a transition from a non-existent state to a circulatable state) corresponds to the complicated operation.

An example of the internal structure of the remote control transmitter 12A is shown in FIG. The internal configuration of the other remote control transmitter 12B may be the same.

However, the remote control transmitters 12A and 12B do not necessarily have to be products of the same manufacturer. On the other hand, it is necessary that the functions of the remote control transmitter 12A and the remote control receiver 11A correspond to each other and that they are basically products of the same manufacturer. Similarly, the functions of the remote control transmitter 12B and the remote control receiver 11B are also the same. Correspondingly, it is necessary that the products are basically manufactured by the same manufacturer. Therefore, the remote control transmitter 1
If 2A and 12B are products of different manufacturers,
The remote control receivers 11A and 11B are usually products of different manufacturers.

(A-1-1) Internal Configuration of Remote Control Transmitter In FIG. 4, the remote control transmitter 12A includes a wireless transmission section 5
4, a transmission processing unit 55, a processor 56, a procedure storage unit 57, an operation detection unit 58, and an operation response unit 59, and the operation switches 51 to 53 have the operation detection unit 5
8 is provided.

Of these, the wireless transmission unit 54 is a portion facing a wireless reception unit 61, which will be described later, of the remote control receiver 11A via a space as a wireless transmission path, and receives from the transmission processing unit 55 via a predetermined signal line. The wireless signal WL1 corresponding to the transmitted signal WS is wirelessly transmitted. Therefore, the wireless transmission unit 54 includes an antenna system for transmission, a filter circuit, and the like. The radio signal WL1 may be a weak radio wave having a frequency band of, for example, about 300 MHz or 400 MHz and a transmission power of, for example, about 1 mW.

Further, the transmission processing section 55 has a function of executing necessary processing such as coding processing and modulation processing, and according to the transmission processing signal RP supplied from the processor 56,
The content of the transmission signal WS to be generated is changed.

In the case of the remote control transmitter 12A, the content of the transmission signal WS is, for example, the specified shutter operation or
Since it is a finite number determined according to the type of ID registration operation, etc., the source of information to be transmitted (this source may be, for example, a ROM (Read Only Memory)) is also inside the transmission processing unit 55. And the transmission processing signal RP
According to the above, one transmission information may be selected and read from the generation sources.

Here, the ID means that the remote control receiver 11A may be confused because the frequency bands used are the same (for example, the frequency used by the remote control transmitter 12B is the same as 12A). Yes, if the distance between the remote control receivers 11A and 11B is not sufficiently long, the remote control transmitter 12B can uniquely identify this) and truly wirelessly transmits to the remote control receiver 11A. Shutter 14 based on only the wireless signal WL1 transmitted from the remote control transmitter of the user
It is an identifier used for performing the operation of A and the like. Therefore, the remote control transmitter 12A needs a certification mechanism (not shown) for accommodating the ID in the wireless signal WL1 each time the wireless transmission is performed, and the remote control receiver 11A identifies the ID and performs user authentication. A verification mechanism (not shown) for performing (or terminal authentication) is required.

In the case of a sheet shutter, it is often placed inside a building such as a factory on a wall that separates a room from another room, and is mechanically weaker than a slat shutter. Considering that the security function is weak, there is no other remote control transmitter (for example, 12B) within the reception range of the remote control receiver 11A,
In an environment in which the shutter operation can be truly performed by the user U1, it is considered that there is little trouble even if the certification mechanism and the verification mechanism are omitted.

The processor 56 for outputting the transmission processing signal RP to the transmission processing section 55 is the remote controller transmitter 12A.
CPU (central processing unit).

The operation detecting section 58 provided with the above-mentioned three operation switches 51 to 53, which is the only remote operation means for the user U1 who operates the remote control transmitter 12A whose functions have been saved to the maximum, has the operation switches 51 to 53. Reference numeral 53 is a portion that outputs the operation detection signals PB1 and PB2 when the pressing stroke reaches a predetermined length.

The operation detection signal PB1 takes different states depending on the operation switch that detects the depression, and the operation procedure is temporarily stored in the procedure storage unit 57.

The procedure storage section 57 is a section for determining what operation or input data the temporarily stored procedure specifies, and supplying the determination signal DS, which is the determination result, to the processor 56.

As with the PB1, the operation detection signal PB1 supplied to the operation response section 59 at the same time that the operation detection signal PB1 is supplied to the procedure storage section 57 is also in accordance with the operation switch that has detected the depression. Although different states may be adopted, in the present embodiment, the operation switch 51
It is assumed that the same state is maintained without distinguishing between ~ 53.

The operation response unit 59 which receives the operation detection signal PB2 may be a sound generator such as a buzzer,
This is a part that outputs a response output RA in order to notify the user U1 that depression of the operation switches 51 to 53 has been effectively detected. In the present embodiment, the operation switches 51 to 5
Since no distinction is made between the three, the user U1 hears the buzzer sound having a constant pitch and a constant tone color as the response output RA when any operation switch is sufficiently depressed.
As a result, the user U1 can auditorily confirm the effectiveness of the switch operation.

For example, when operating a keyboard with a personal computer or the like, in an environment with a much larger and richer user interface than the remote control transmitter 12A, whether or not a certain key press is recognized by the machine. Although it can be easily confirmed by visually observing a screen display such as a bitmap display, the remote control transmitter 12A which requires a high degree of portability
From the viewpoint of saving the above-mentioned function, the function is cut down to the limit, so how can a user operate efficiently with a small configuration (here, the remote controller transmitter 12
It is important to confirm whether or not it is recognized by A).

Although the response output RA of the operation response unit 59 is a constant tone and a constant tone color buzzer sound here, if necessary, it may be a combination of the depressed operation switches 51 to 53 or the depressed operation switches at the same time. The pitch or tone color may be changed accordingly. The user U1 is notified that the operation of the operation switch is effectively detected by a visual means using a light emitting element such as an LED (light emitting diode) or the like, not limited to the auditory means by the sound generator. Alternatively, visual means and auditory means may be used together.

In the state shown in FIG. 2, a shutter operation system composed of a shutter device 14A located on the user U1 side, a remote control receiver 11A, and a remote control transmitter 11A,
Since the shutter operation system composed of the shutter device 14B, the remote control receiver 11B, and the remote control transmitter 11B located on the user U2 side is originally a separate system, the shutter device 14A is basically the user U1. The shutter operation as instructed using the remote control transmitter 11A is performed, and the shutter device 14B performs the shutter operation as instructed by the user U2 using the remote control transmitter 11B.

However, in the case of this embodiment, the buffer space 1
Since the purpose is to shut off the outside air by using No. 3, the shutter devices 14A and 14B must be prohibited from simultaneously performing the opening operation.

This prohibition is performed by the remote control receivers 11A and 11A.
It is performed based on the communication between B.

It is preferable that the remote control receiver 11A (, 11B) also has the functions saved as much as possible from the viewpoint of compactness and cost reduction, but unlike the remote control transmitter 12A, it is normally fixedly arranged. Therefore, the level of demand for saving functions is not so high. Therefore, saving the functions of the remote control receivers 11A and 11B is required from the viewpoint of cost. For example, it is advantageous not to mount a bidirectional communication function (negotiation function or the like) between the remote control receivers 11A and 11B, which brings about an increase in required processing capacity.

An example of the internal configuration of the remote control receiver 11A is as shown in FIG. An example of the internal configuration of the remote control receiver 11B may be the same as that in FIG. 1, but here, in FIG.
The description will proceed assuming that the remote control receiver 11A is mainly shown in FIG.

(A-1-2) Internal Configuration of Remote Control Receiver In FIG. 1, the remote control receiver 11A has a radio receiving section 61, a reception processing section 62, a processor 63, a motor control section 64, and an input. Unit 65, output unit 66, deceleration start position storage unit 67, delay time storage unit 68, comparison unit 6
9 and a timer 70.

Of these, the radio receiving section 61 is provided with an antenna system for reception, a filter circuit, etc., and is a section for receiving the radio signal WL1 transmitted from the remote control transmitter 12A via a space (the radio transmission path). , And outputs a reception signal WS corresponding to the received wireless signal. The transmission signal W
The reception signal WS, which is a signal corresponding to S, is supplied to the reception processing unit 52 via a predetermined signal line.

The reception processing section 52 receives the received signal W
This is a part that performs necessary processing such as demodulation processing and decoding processing on S to generate and output a reception processing signal RP.

The reception processing signal RP is the transmission processing signal R
A signal corresponding to P can function as a shutter operation designation signal that designates a shutter operation such as opening, closing, or stopping of the shutter, but a factory that manufactures and assembles the remote control transmitter as necessary. It also functions as a signal for instructing the registration of the ID assigned to the remote control transmitter 12A when it is shipped from.

The motor control unit 64 receives the motor control signal C corresponding to the open / close control signal CS received from the processor 63.
This is a part that supplies C to the motor MA and realizes the shutter operation desired by the user (for example, U1). Therefore, the power supply (forward rotation, reverse rotation, supply stop, etc.) to the motor MA is controlled according to the motor control signal CC.

The motor control unit 64 also has a function of incorporating an encoder and outputting an encoder pulse EP which is output according to the rotation amount of the output shaft of the motor MA. The encoder pulse EP is supplied to the processor 63. In the processor 63, the shutter curtain 1 is counted by counting the number of the encoder pulses EP.
It is possible to recognize the position of the lower end portion 14AD of 4AC (the position in the direction along the arrows D1 and D2).

The motor control unit 64, if necessary,
The remote controller receiver 11A may be provided outside the remote controller receiver 11A instead of as a part of the remote controller receiver 11A.

Reception processing signal RP from the reception processing unit 62
The processor 63 that receives the
This is the part that functions as the CPU of A. The processor 63 uses the encoder pulse EP to generate the lower end portion 14
As a method of recognizing the position of AD, a continuous counting method,
There is a discontinuous counting method.

In the continuous counting method, when counting the number of the encoder pulses EP, stop in a completely open state,
This is a method of maintaining the count value of the counter even if it is stopped in the completely closed state, stopped at an intermediate position, etc., for example, it counts up when performing an opening operation and counts down when performing a closing operation. To do. According to this method, the count value and the position of the lower end portion 14AD always have a one-to-one correspondence, and the count value at any time point indicates the position of the lower end portion 14AD at that time point.

On the other hand, in the discontinuous counting method, the count value is reset to the initial value (for example, 0) every time the stop in the completely open state, the stop in the completely closed state, the stop in the intermediate position, etc. are performed. It is a method to do. In this method, the count value indicates the relative movement distance of the lower end portion 14AD in one operation (for example, opening operation).

Although any method can be used, in the present embodiment, the processor 63 uses the continuous counting method.

Further, the processor 63 is arranged such that the remote control receiver 11B facing the input section 6 via a predetermined transmission path.
The other operation notification signal NT2 transmitted to
It also has the function of receiving as.

The input section 65 for supplying the signal N2 to the processor 63 is connected to the output section of the remote control receiver 11B (a component corresponding to the output section 66 in FIG. 1) facing the output section via the transmission line. . Although it is possible to use a wireless transmission line as the transmission line 15, a wired transmission line is used here.

Specifically, the wired transmission line 15 can be constructed by using, for example, a twisted pair cable (twisted pair cable) or a coaxial cable. Remote control receiver 1
The signal transmission in the direction from 1A to 11B and the signal transmission in the opposite direction from the remote control receiver 11B to 11A may be performed using the same signal line, but in this embodiment, each direction is used. A separate signal line is used in order to prevent the deterioration of communication quality due to the collision between the other-operation notification signal NT2 transmitted to the device and the own-operation notification signal NT1 described later.

However, in the case of this embodiment, the other operation notification signal NT2 indicates whether or not the opening operation is performed. Since it has an extremely small amount of information, its time width is narrow.
Since it is considered that such collisions occur stochastically extremely rarely, there is practically no problem even if the same signal line is used.

The processor 63 receives the signal N2 from the input section 65.
When it receives, the state ES2 is written in the other operation information flag 71 according to the content of N2. When the processor 63 tries to perform the opening operation (from the completely closed state) of the curtain 14AC, it always inspects the contents of the state ES2 of the other operation information code love 71.

Each remote control receiver 11A, 1 of this embodiment
1B includes at least both shutter devices 14A and 14A.
To the extent that both B can be prevented from opening,
It is necessary for both parties to be aware of each other's operation status. Therefore, it is considered that at least two states are required for the state of the other operation notification signal NT2. That is, the shutter curtain 14BC is in a closed state indicating that the shutter curtain 14BC is currently completely closed, and a non-closed state indicating that the shutter curtain 14BC is not completely closed (including, for example, intermediate stop, fully open, and moving). Is.

If the other operation notification signal NT2 has two states, it can be displayed by 1 bit, which is also effective for saving functions. As long as the other operation notification signal NT2 in the non-closed state is received, the shutter device on the remote control receiver (11B for 11A) side of the other party receives the other operation notification signal NT2 in the closed state. It is necessary to consider that it is in an open state.
If there are two other operation notification signals NT2, the signal N2 is also two.
On the street.

Next, the output unit 66 has the same function as the output unit on the remote control receiver 11B side of the other party already described,
A self-operation notification signal N corresponding to the other-operation notification signal NT2
This is the part that outputs T1. The other operation notification signal NT2 is the shutter curtain 14 on the remote control receiver 11B side of the partner.
While the operation state of BC is shown, the self-operation notification signal NT1 shows the operation state of the shutter curtain 14AC on the remote control receiver 11A side. Therefore, the automatic operation notification signal NT1 and the signal N1 which is the basis thereof.
There are also two states, i.e., the closed state and the non-closed state.

The other operation information flag 71 is a flag for storing the state ES2 of the other remote control receiver (that is, the remote control receiver 11B) as viewed from the remote control receiver 11A, and the rewriting of the state ES2 of this flag is received. The processor 63 performs the operation according to the content of the signal N2. Therefore, the state ES2 indicates either the closed state or the non-closed state, and when the ES2 is the non-closed state, the open / close control signal C for instructing the opening operation by the processor 63.
It does not output S.

Similarly, the self-operation information flag 72 is a flag for storing the state ES1 of the remote control receiver 11A itself, and the state ES1 of this flag is rewritten by the processor 63 based on its own operation state. Therefore, the state ES1 also indicates either the closed state or the non-closed state like the state ES2, but at least the state ES1 and the state ES2 become the non-closed state at the same time in the configuration of the present embodiment. ,prohibited.

For example, when the processor 63 receives the reception processing signal RP (radio signal WL1) instructing the opening operation of the shutter device 14A, the other operation information flag 71.
If the state ES2 is a closed state, the signal N1 for transmitting the non-closed automatic operation notification signal NT1 is supplied to the output unit 65, and the state ES1 of the automatic operation information flag 72 is changed to the non-closed state. An opening / closing control signal C that causes the motor control unit 64 to execute the opening operation of the shutter curtain 14AC.
However, if the state ES2 of the other operation information flag 71 is the non-closed state, the signal N1 for transmitting the non-closed self-action notification signal NT1 is not supplied to the output unit 65. , The status ES1 of the automatic operation information flag 72
Keeps the closed state and does not supply the opening / closing control signal CS for causing the motor controller 64 to perform the opening operation of the shutter curtain 14AC.

The deceleration start position storage section 67 connected to the processor 63 is a section for storing deceleration start position information indicating the deceleration start position DG1. Deceleration start position DG1
Is the floor surface FL1 reached by the lower end portion 14AD when completely closed.
It is a predetermined position higher than (see FIGS. 1 and 5). When the processor 63 recognizes that the lower end portion 14AD has reached the deceleration start position DG1 by counting the number of encoder pulses EP by the continuous counting method, at that timing, the power supplied to the motor MA is reduced. Stop the supply.

In FIGS. 5A and 5B, the lower end portion 14
It shows that the count value relating to the number of encoder pulses EP is 0 in the fully open state in which AD is located at the top, and the count value is 7000 in the fully closed state in which it is located at the bottom. Then, the deceleration start position DG1 is
It is an intermediate position of the count value 5000. Between the complete closing position and the deceleration start position DG1, the encoder pulse E
There is a distance of 2000 pulses in the number of P, and the motor M
The shutter curtain 14AC, which has been cut off from the supply of mechanical energy from A, has a distance of 2000 pulses.
It will move by inertia while resisting friction with the guide rail GR (see FIG. 2), wind pressure, etc., gradually decelerating, and reaching the floor surface FL1 under a relatively weak impact and stopping. .

The delay time storage section 68 is a section for storing information indicating the delay time TMD. The delay time means the lower end portion 14 of the shutter curtain 14AC which is still closed.
This is the time required from when AD reaches the deceleration start position DG1 until it almost reaches the floor surface FL1. This delay time is the lower end portion 14 when the deceleration start position DG1 is reached.
Although it changes according to the moving speed of AD (normally almost constant speed) or the acceleration of deceleration, as an example, the moving speed of the lower end portion 14AD at the time of reaching the deceleration start position DG1 is 1.2 m / s. If the height from the floor surface FL1 to the deceleration start position DG1 is about 30 cm, 0.3
It may be about a second.

When the lower end portion 14AD reaches the floor surface FL1 completely when the delay time TMD elapses,
Although it is advantageous to enhance the effect of blocking the outside air, the user U1 or U2 can visually recognize the situation where the two shutter curtains 14AD and 14BC are not completely closed even when the floor FL1 is not completely reached. If the lower end portion 14AD is close to the floor surface FL1 to the extent that it does not exist,
It is possible to increase the reliability of the interlock function.

The timer 70 is a part for measuring the time under the control of the processor 63. The timer 70 can be configured by, for example, a counter that counts the number of clock pulses supplied at constant time intervals. The processor 63 causes the timer 70 to start measuring time at the timing when the lower end portion 14AD reaches the deceleration start position DG1. Once the time measurement is started, the measurement time TM1 generated by the timer 70 monotonically increases from the initial value (for example, 0).

The comparing unit 69 compares the value of the delay time TMD read from the delay time storing unit 68 with the measurement time TM1 generated by the timer 70, and when the measurement time TM1 reaches the delay time TMD. , The arrival signal LD1 is supplied to the processor 63.

The feature of this embodiment is that the lower end portion 14AD is
Does not reach the deceleration start position DG1 but receives the arrival signal LD1.
However, there is a point to recognize the closed state of the shutter curtain 14AC.

Therefore, when the processor 63 receives the arrival signal LD1, the processor 63 rewrites the state ES1 of the self-operation information flag ES1 from the non-closed state to the closed state and transmits the signal N1 indicating the closed state to the output section 66. The automatic operation notification signal NT1 in the closed state is transmitted. By receiving the self-operation notification signal NT1 in the closed state, the remote control receiver 14B can perform the opening operation from the completely closed state maintained until then.

However, in the structure of this embodiment, before the shutter curtain 14AC in the closing operation has passed the deceleration start position DG1 and before reaching the floor surface FL1 (as an example, the lower end portion 14AD is shown in FIG. There is a possibility that the wireless signal WL1 instructing the opening operation may arrive from the remote control transmitter 12A when it is in the position shown in). In that case, the processor 63 immediately resets the measurement time TM1 of the timer 70 to the initial value, and transmits the opening / closing control signal CS instructing the motor control unit 64 to perform the opening operation. As described above, since the seat shutter is made of a light material, it is possible to immediately reverse the seat shutter in such a case and shift from the closing operation until then to the opening operation.

When this inversion is performed, the arrival signal LD is not supplied to the processor 63.
Of course, the closed operation notification signal NT1 is not transmitted.

The measurement time TM1 used here can be replaced with another physical index.

For example, the moving distance of the lower end portion 14AD (this moving distance can be dynamically calculated based on the number of encoder pulses EP using the continuous counting method).
It may be measured itself, or the moving speed of the lower end portion 14AD may be measured. Focusing on the point that the lower end portion 14AD decelerates after passing through the deceleration start position DG1, it should be recognized that the moving speed of the lower end portion 14AD becomes equal to or lower than a predetermined value and the floor surface FL1 is sufficiently approached. Is possible.

In order to obtain the effect of the present embodiment, the most reliable and excellent physical index is the moving distance, but it can be said that the time (TM1) is preferable from the viewpoint of ease of measurement. In the case of speed, the advantages and disadvantages differ depending on how the speed is detected, but when measuring the speed, that is, when dynamically calculating the speed based on the actual travel distance, It is close to the case where the moving distance is used as an index, and is close to the case where time is used as a physical index when approximating a speed change with a static model according to elapsed time.

Of the above components, flags 71 and 72
With regard to the above, since it only needs to function when the composite shutter system 10 is in operation (when power is supplied), a normal RA
Although M (random access memory) can be used, deceleration start position storage unit 67 and delay time storage unit 68
With regard to (2), it is necessary to maintain the stored contents even when power is not supplied and be prepared when power supply is restarted. For this reason,
The deceleration start position storage unit 67 and the delay time storage unit 68.
For this, a ROM (Read Only Memory) may be used. If the memory content needs to be rewritten, EE
PROM (Flash memory: Electrical Erasable
It is also preferable to use a writable ROM such as a programmable ROM) for the deceleration start position storage unit 67 and the delay time storage unit 68.

However, the ROM can be replaced with a magnetic storage means, a RAM having a sufficient power source backup mechanism, or the like, if necessary. Generally, the price of the memory itself is higher in the EEPROM than in the RAM, but in consideration of the power consumption for backup and the like, the operating cost of the RAM is likely to be higher than that of the RAM. In actual implementation, an advantageous one may be selected in consideration of these points.

The operation of this embodiment having the above-mentioned structure will be described below with reference to FIG.

The flowchart of FIG. 6 shows steps S10 to S19.
It consists of steps.

(A-2) Operation of the Embodiment The power is turned on to the two shutter devices 14A and 14B that form the composite shutter system 10, and the system 1
The wireless signal WL1 which starts the operation of 0 and instructs the closing operation
From the remote control transmitter 12A to the remote control receiver 11A
To the remote controller receiver 1 (S10, S11).
1A inspects whether the shutter curtain 14AC can be closed (S12).

In the above description, the case where the opening operation cannot be performed has been described, but the case where the closing operation cannot be performed has not been described. As a case where step S12 is branched to the No side and the closing operation cannot be performed, for example, an obstacle detection sensor (not shown) has a lower end portion 14A in which the closing operation is performed.
An example is when an obstacle is detected in the direction of D. In such a case, the closing operation is stopped so that the lower end portion 14AD does not come into contact with the obstacle.

If there is no obstacle detected, step S12
During the closing operation of the curtain 14AC by branching to the Yes side (that is, the motor M
While the electric power is being supplied to A), the presence or absence of the lower limit input, that is, the lower end 14AD is the deceleration start position D
It is inspected whether or not it has reached G1 (S14). The wireless signal WL1 in step S11 is, for example, the lower end portion 14
When the AD is higher than the deceleration start position DG1 and the closing operation to the completely closed position is instructed, the lower end portion 14AD always passes through the deceleration start position DG1 in the process of the closing operation. Will be done. The step S14 is to detect the passing point.

When the lower end portion 14AD passes the deceleration start position DG1, the step S14 branches to the Yes side and the processor 63 stops the power supply of the motor MA and starts the time measurement by the timer 70 (S15).
How the processor 63 stops the power supply to the motor MA depends on the functional specifications of the motor MA and the motor control unit 64. For example, the processor 63 outputs an opening / closing control signal CS instructing the stop. Therefore, it is possible to stop the power supply.

The value of the time TM1 measured by the timer 70 is
When a predetermined X (here, X = TMD) seconds are reached, step S16 branches to the Yes side, and the comparison unit 6
9 supplies the arrival signal LD1 to the processor 63, but before the delay time TMD elapses after the lower end portion 14AD has passed the deceleration start position DG1, the opening operation input (the remote control transmission of the wireless signal WL1 instructing the opening operation is performed. (Reception from the device 12A) is performed, step S19 branches to the Yes side, and the process returns to step S11 again. In this case, since the time measurement by the timer 70 is stopped at this point, the arrival signal LD1 is not supplied to the processor 63.

When the processor 63 branches to the Yes side in step S16 and receives the reaching signal LD1, the processor 63 rewrites the state ES1 of the self-operation information flag 72 from the non-closed state to the closed state and transmits the signal N1 indicating the closed state. Then, the output unit 66 is caused to transmit the automatic operation notification signal NT1 in the closed state.
As a result, the remote control receiver 11B also has the authority to perform the opening operation (open operation right) that the remote control receiver 11A had until then (S17).

By receiving the self-operation notification signal NT1 in the closed state, the remote control receiver 14B can obtain the opening operation right and perform the opening operation from the completely closed state maintained until then. become. Actually, whether or not the shutter device 14B performs the opening operation depends on whether or not the user U2 uses the remote control transmitter 12B to instruct the opening operation, but if the user U2 instructs the opening operation. The remote control receiver 11B controls the motor MB to keep the shutter curtain 1 completely closed until then.
4BC will be opened.

Along with this opening operation, the remote control receiver 1
From 1B to 11A, the other operation notification signal N in the non-closed state
T2 is supplied, and the processor 63 causes the other operation information flag 7
By rewriting the state ES2 of 1 from the closed state to the non-closed state, only the remote control receiver 14B has the opening operation right.

After that, by the remote control receiver 14B,
Processing according to the flowchart shown in FIG. 6 may be performed.

(A-3) Effects of the Embodiment According to this embodiment, the two shutter devices (14A, 14B) are both completely operated by setting the deceleration start position (DG1) and the delay time (TMD). Since it is possible to guarantee that there will be no situation that is not closed,
It is possible to enhance the reliability by increasing the effect of blocking the outside air.

Further, in the present embodiment, it is possible to prevent the user (U1, U2) from visually observing the situation where neither of the two shutter devices is completely closed by setting the deceleration start position and the delay time. Therefore, it is possible to give the user a sense of security and improve the credibility.

(B) Other Embodiments In the above embodiment, the radio signal WL1 has a frequency band of about 300 MHz or 400 MHz and a transmission power of 1 m.
Although it was a weak radio wave of about W, the applicable range of the present invention is not limited to this. Radio waves having a frequency higher or lower than this may be used, or infrared rays or the like may be used. Also, the transmission power may be higher or lower than this.

Further, in the above-mentioned embodiment, the interlocking relation of the operation related to the opening and closing of the shutter is held as a predetermined interlocking relation. However, if necessary, the interlocking relation related to the operation other than the opening and closing of the shutter is held. You may do it.

Further, in the above-described embodiment, the condition for maintaining the interlocking relationship is that one of the shutters is in the closed state, but such a condition depends on the content of the interlocking relationship to be held. It changes.

In the above embodiment, it is necessary to prevent the two shutter devices from being opened at the same time for the purpose of blocking the outside air. However, depending on the purpose, the two shutter devices may be closed at the same time. It may be necessary to prevent it. The present invention can be applied to such a case. In that case, it is necessary to read the opening and opening operations in the description of the above embodiment as closing and closing operations and read the closing and closing operations as opening and opening operations.

Further, the opening / closing operation means only the opening direction.
It means a moving operation only in the closing direction or in both the opening and closing directions.
Further, "closed" is a concept that means a movement in the direction of closing the opening when there is an opening, and means the forward movement of the opening / closing body including feeding, sliding movement, expansion, etc. When there is an opening, it is a concept that means moving in the direction of opening it, and means retreating of the opening / closing body including winding, contraction, folding and the like.

In the above embodiment, the operating state signals NT1 and NT2 other than itself have two states, that is, the non-closed state and the closed state, but they may have three or more states.

For example, among the non-closed states, the fully opened state and the intermediate stopped state may be distinguished from each other, and whether the lower end portion (eg, 14AD) is in the stopped state or in the moving state is discriminated. You may do it.

In the above embodiment, the closed self-operation notification signal NT1 is not transmitted until the delay time TMD elapses even when the lower end portion (for example, 14AD) that is closed passes the deceleration start position DG1. However, the automatic operation notification signal TN1 in the closed state may be transmitted immediately after passing through the deceleration start position. This is equivalent to a remote control receiver (for example, 11B) not having the opening operation right receiving a notice regarding the granting of the opening operation right, and the side of the remote control receiver (here, 11A) monopolizing the opening operation right. The operating state of can be recognized to some extent on the remote control receiver 11B side.

In this case, however, in preparation for the case where the remote control receiver 14A receives the wireless signal WL1 instructing the opening operation before the delay time TMD elapses after the lower end portion 14AD has passed the deceleration start position DG1. Also on the remote control receiver 14B side, it is necessary not to perform the opening operation from the time when the closed self-operation notification signal TN1 is received from the remote control receiver 14A until the delay time TMD elapses.

On the side of the remote control receiver 14A, a radio signal W for instructing the opening operation until the delay time TMD elapses after the lower end 14AD has passed the deceleration start position DG1.
When L1 is received by the remote control receiver 14A, it is necessary to send to the remote control receiver 11B a non-closed state self-operation notification signal NT1 that cancels the previously transmitted closed state self-operation notification signal NT1.

When the physical index is time, the remote control receiver 14B which has received the closed operation notification signal NT1 can easily check whether the elapsed time has reached the delay time TMD. However, in the case of a moving distance or the like, it is necessary to enable the remote control receiver 11B to receive the encoder pulse EP indicating the rotation amount of the output shaft of the motor MA, The cable routing between the shutter devices 14A and 14B and the functions of the remote control receivers 11A and 11B may be complicated.

Since the sheet shutter is used in the above embodiment, the structure of the lower end portion (14AD, etc.) is simple (for example, a weight is included if necessary). However, with slat shutters,
Some of the lower end portions have a cushion mechanism or the like for absorbing the impact when reaching the floor surface FL1 and elastically contacting the lower end portion with the floor surface even in the completely closed state. The present invention can also be applied to a shutter having such a lower end portion.

Further, in the above embodiment, until the physical index (measurement time TM1) reaches the reference value (TMD), the opening operation instruction is accepted even after the lower end portion 14AD has passed the deceleration start position DG1. After the lower end portion 14AD has passed the deceleration start position DG1, the opening operation instruction may be ignored immediately after that.

Further, the deceleration start position D is provided at the lower end 14AD.
In the case where the closing operation instruction that has passed G1 is an instruction to shift to the completely closed state, for example, when the closing operation is started, at a time point before the lower end portion 14AD reaches the deceleration start position DG1. Alternatively, the input opening operation instruction may be ignored.

Further, if the reference value for the physical index is set to a large value, and the physical index is time, for example,
The place where the lower end portion 14AD reaches the floor surface FL1 in 0.3 seconds may be set to about 0.5 seconds, and the opening operation instruction may be ignored until the 0.5 seconds has elapsed. Thus, the priority of the opening operation can be given to the remote control receiver (for example, 14B) which has been kept in the completely closed state until the difference of about 0.2 seconds. of course,
The 0.2 seconds may be a longer time.

Further, in the above embodiment, the shutter device is two, that is, 14A and 14B, but it is also possible to construct a composite shutter system including three or more shutter devices.

In the above embodiment, the number of functions mounted on the remote control transmitter is reduced as much as possible and as many functions as possible are distributed to the remote control receiver side.
If necessary, it is possible to adopt a configuration in which a part of the functions mounted on the remote control receiver is mounted on the remote control transmitter side.

Further, in the above embodiment, the operation switch is the PBS type switch, but the present invention is not limited to the PBS type switch. A slide switch, a rotary switch, or the like may be used, and various kinds of switches that respond to changes in pressure, temperature, static electricity, or the like can be used.

In the above embodiment, mainly
Although the present invention is applied to the sheet shutter, the present invention can be applied to various shutters such as a garage shutter and a window shutter other than the sheet shutter.

Furthermore, the present invention can be applied not only to shutters, but also to a mixing system for other opening / closing devices such as doors, windows, overhead doors, roll screens (for example, blackout curtains), blinds and awning devices. Is.

Further, in the above description, the direction of information flow is basically a unidirectional direction from the remote control transmitter to the remote control receiver, but the applicable range of the present invention is limited to such unidirectional communication. It is not something that will be done.

That is, the remote control transmitter is replaced with an operation transmitter / receiver which is a transmitter / receiver for remote operation rather than a communication device dedicated to transmission, and the remote controller receiver is not a communication device dedicated to reception but transmission / reception for remote operation. It may be replaced with an operated transceiver that is a machine, and full-duplex communication or half-duplex communication may be performed as necessary.

At this time, the signal included in the radio signal transmitted from the operating transceiver to the operated transceiver may be an operation state instruction signal for instructing the shutter operation or the like,
On the contrary, the signal included in the wireless signal transmitted from the operated transceiver to the operation transceiver may be an operation state report signal for reporting the current state of the shutter operation and the like.

The operation status report signal indicates that the shutter operation status at that time is, for example, "fully open status", "fully closed status", "intermediate stop status (partially open and stopped)". , “Opening operation”, “closing operation”, “abnormality occurrence”, or the like.

In this case, by receiving the operation state report signal, the user of the operation transceiver can recognize that the shutter operation state is, for example, the "closing operation in progress".

Further, the operating transceiver may be replaced with a portable receiver and the operated transceiver may be replaced with a fixed transmitter. In this case, the direction of information flow is unidirectional from the fixed transmitter to the portable receiver. The system configuration may be such that only such one-way communication is always performed, or the system configuration may be such that such one-way communication can be performed only when necessary in accordance with communication direction mode switching.

That is, such unidirectional communication may be carried out between the operating transceiver and the operated transceiver only when necessary according to the communication direction mode switching.

As described above, according to the present invention, the reliability and reliability of the switching system and the switching device can be improved.
