Abstract

PROBLEM TO BE SOLVED: To inhibit open-close operation from a preset inhibition-controlled object even when there is the open-close operation during an obstruction contact period at the time of opening and closing of a shutter. SOLUTION: A control means 3 drives and controls an open-close machine M in the corresponding direction and the shutter is opened and closed by operating an operating section 4 installed on a wall, etc., in the side section of the shutter. When the shutter is brought into contact with an obstruction at the time of the opening and closing of the shutter, a sensing means 1 radio-transmits a sensing signal, and the control means 3 conducts control such as stopping. Even when there is the operation of a remote controller 5 at a remote place as an inhibition-controlled object during the period of the contact of the obstruction, the control means 3 makes the operating signal ineffective, and opening and closing by working the remote controller 5 is suppressed. Opening and closing by the operation of the remote controller 5 are informed to the outside by a sound, light, etc., from an information means 9 at the same time, and no trouble of the remote controller 5 is transmitted.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shutter control device which is opened and closed by a wired operation unit and a wireless remote controller. The present invention relates to a shutter control device that inhibits shutter opening and closing.

[0002]

2. Description of the Related Art There is a shutter control device in which, when an obstacle is detected during a shutter lowering operation, the shutter is stopped or reversed to avoid danger from the obstacle. In addition to opening and closing the shutter, in addition to operating the operation switch of the operation unit provided on a wall or the like connected by wire from the shutter control device, the remote control can be performed by a remote control at a location remote from the shutter. There is also. In such a shutter control device, when the operation switch of the operation unit or the operation switch of the remote controller is pressed once, the shutter is continuously opened and closed by the self-holding circuit or the like until the shutter reaches the upper limit or the lower limit position. is there.

[0003]

Since the remote controller is portable, the shutter may be accidentally opened or closed during the period when the obstacle is in contact with the above-mentioned obstacle or during the continuous opening and closing operation. It is conceivable that a remote control operation may be performed from a distant position where the open / closed state cannot be seen and without checking the open / closed state.

[0004] In the case described above, if the operation instruction by the remote control operation is a closing operation instruction, there is a possibility that the shutter may operate in the closing direction even though the obstacle has not been removed. The same applies to the case where the operation unit is provided in a wired manner and cannot be seen through a location away from the shutter, behind a shadow, or the like.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and even if there is a shutter opening / closing operation from a preset prohibited control target during an obstacle sensing control period at the time of opening / closing a shutter, this operation is performed. It is an object of the present invention to provide a shutter control device that prohibits the shutter.

[0006]

According to a first aspect of the present invention, there is provided a shutter control device, comprising: a sensing unit for outputting a sensing signal at the time of contact with an obstacle when the shutter is opened and closed; An operation switch for opening and closing the shutter; operating means 4 and 5 for outputting an operation signal corresponding to the operation wirelessly or by wire; and controlling and driving a switch M connected to the shutter to receive the sensing signal. Control means 3 for controlling the shutter to detect an obstacle at times, and for invalidating the operation signal input from the operation means 4 and 5 when the detection signal is received, and prohibiting the opening and closing of the shutter by the operation means 4 and 5. It is characterized by doing.

The operating means may be a remote controller 5 which is opened and closed at a location remote from the location where the shutter is provided, and which transmits an operation signal wirelessly. Alternatively, when the sensing signal is received, the operation signal from the remote controller 5 may be invalidated to prohibit the opening and closing of the shutter by the remote controller 5.

In the control means 3, specific operation switches of the operation means 4 and 5 are set in advance in the control means 3 as prohibition control targets for invalidating the operation signal when the sensing signal is received. Prohibited control target setting unit 7a
When receiving the sensing signal from the sensing means 1, information indicating the reception of the sensing signal is held, and during the holding period of the information indicating the reception of the sensing signal, a state setting for determining that the operation of the prohibited control target is invalid is set. A configuration is provided in which a unit 7b and a release unit 10 that is operated by releasing the obstacle contact state and releases the holding state of the information indicating the reception of the sensing signal held in the state setting unit 7b are provided. be able to.

According to a fourth aspect of the present invention, the control means 3 is connected to a notification means 9 for emitting a sound or light, and the control means 3 invalidates the operation of the operation means 4 and 5. During the period, a notification to that effect may be provided externally via the notification means 9.

When the shutter comes into contact with an obstacle during opening and closing of the shutter, the sensing means 1 outputs a sensing signal, and the control means 3 controls the sensing of the obstacle correspondingly. That is, even if an open / close operation signal is transmitted from the remote controller 5 during the obstacle sensing control period, the control means 3 invalidates this operation and inhibits the opening / closing of the shutter. As a result, the shutter is not driven to open and close even if the shutter is opened and closed by the remote controller 5 at a remote location where the open / close state of the shutter cannot be seen.

[0011]

FIG. 1 is a block diagram showing a shutter control device according to the present invention. The shutter is provided with sensing means 1 for detecting contact with an obstacle at the time of opening and closing. The sensing means 1 is provided with, for example, a seat plate switch that operates when an obstacle comes into contact with a seat plate of a shutter curtain, and wirelessly transmits a sensing signal to the receiving unit 2 wirelessly by light or the like at the time of operation. Input to the control means 3;
Performs an obstacle sensing control described later at the time of input.

The control means 3 is connected with an operation section 4 as an operation means and a remote controller 5, and controls opening and closing of the shutter in a corresponding direction by operating an operation switch. The operation unit 4 is provided on a wall or the like on the side of the shutter, has operation switches for opening / closing stop operation, is connected to the control unit 3 via a connection line by wire, and the control unit 3 opens and closes the shutter based on this operation. Control. The remote controller 5 has an operation switch for stopping opening and closing, and is carried by the operator, operated at a remote location away from the shutter, and wirelessly transmits an operation signal to the receiving unit 6 by radio such as radio waves at the time of operation. This operation signal is input to the control means 3, and the control means 3 controls opening and closing of the shutter based on this operation.

The control means 3 has an operation signal detection means 7 and a drive signal output means 8. The operation signal detecting means 7 receives the outputs of the operation unit 4 and the remote controller 5 and self-holds a short-time operation signal output at the time of these operations by a self-holding circuit or the like, and continuously in the same operation direction. Is output to the drive signal output means 8. When the outputs of the operation unit 4 and the remote controller 5 are input simultaneously, one of them is preferentially captured. The drive signal output unit 8 supplies a drive signal to the switch M in accordance with the operation signal output from the operation signal detection unit 7, and drives the shutter to open and close via the switch M. The operation unit 4 described above may be provided at a location away from the shutter.

The sensing signal from the sensing means 1 is input to an operation signal detecting means 7 and a driving signal output means 8. The operation signal detecting means 7 has a prohibition control target setting section 7a and a state setting section 7b. When a sensing signal is input to the operation signal detecting means 7, the state setting section 7b holds information indicating reception of the sensing signal. I do. As the information indicating the reception of the sensing signal, for example, a flag that is a program identifier is used, and the information indicating the reception of the sensing signal is held by a flag set (ON) of the flag storage unit.

During the setting period of this flag, even if an operation signal is input from the prohibition control target set in the setting storage unit of the prohibition control target setting unit 7a, this operation is invalidated, and this operation signal is transmitted to the subsequent drive signal. Prohibiting output to the output means 8 (obstacle sensing control period). This prohibition control target is
The operation unit 4 and the remote controller 5 are set. More specifically, when a plurality of the operation unit 4 and the remote controller 5 are provided, the operation unit 4 and the remote controller 5 can be set. It is possible to designate a specific operation switch among the respective operation switches for opening / closing and stopping to set in the setting storage unit.

For example, when each operation switch for opening and closing the remote controller 5 is set and stored as the object of the prohibition control, the operation signal detecting means 7 controls the opening and closing of the remote controller 5 while the flag is set by the input of the sensing signal. This operation is invalidated even if an operation signal is input. The flag set in the flag storage unit is reset (OFF) by a release instruction of the release unit 10 and returns to a normal state (a state where a sensing signal has not been received).

During the obstacle sensing control period in which the flag is set, the notifying unit 9 outputs a notification signal to the effect that the operation of the prohibited control target has been performed during the obstacle contact state. In response to the notification signal, a buzzer, a lamp, or the like externally notifies that the operation is being performed during the obstacle contact state. The notification means 9 is provided in the vicinity of the shutter or in a room where a shutter manager is resident. The notification signal may be configured to be continuously output until a release command from the release unit 10 is input, or may be configured to be continuously output using the timer 11 for a predetermined time. This release means 1
As 0, an open, close, or other switch may be used, but it is desirable to set a specific switch that is safe to operate, for example, an operation switch for stopping the operation unit 4. Until the flag is set. That is, the obstacle sensing control period is a period from when the obstacle is sensed to when an operation signal of the operation switch serving as the canceling unit 10 is input to the control unit 3.

The driving signal output means 8 performs an obstacle sensing control such as stopping the switch M when the sensing signal is input. As another example of the obstacle sensing control, there is a method of inverting and rising for a predetermined period after stopping by inputting a sensing signal.

Next, the operation of the shutter control device having the above configuration will be described with reference to the flowchart of FIG. Hereinafter, the remote control 5
An example in which is set will be described. When an opening / closing operation is performed using the operation unit 4 or the remote controller 5, the operation signal detecting means 7 detects an operation signal in the control means 3, and the drive signal output means 8 drives the switch M in the same direction to open and close the shutter. I do.

During the opening / closing operation (SP1), the sensing means 1
Detects a contact with an obstacle and outputs a sensing signal (SP2-Y
ES), the drive signal output means 8 performs obstacle sensing control such as stopping the switch M (SP3). When such an obstacle contact is made, the obstacle is normally removed from the opening of the shutter, and the operating unit 4 on the side of the shutter is operated while confirming that the shutter can be freely opened and closed ( SP4-YES), the shutter is opened and closed again (SP5), and thereafter, the opening and closing operation by the remote controller 5 is enabled (S5).
P6).

However, during the obstacle sensing control period (S
In P2-YES), the remote controller 5 performs an opening / closing operation, and when this radio wave is received by the receiving unit 6 provided on the shutter side and input to the control unit 3 (SP7-YES), the signal detecting unit 7 uses this remote control. It is determined that the remote control 5 is an object of prohibition control, and a flag is set to invalidate the operation signal output from the remote controller 5 (SP8). That is, during the above-described obstacle sensing control period, the remote controller 5 may be operated without confirming the open / close operation state from a remote position where the open / close state of the shutter cannot be seen due to the carelessness of the operator or the like. . The receiving unit 6 may receive a radio wave from the remote controller 5 even in such a case. However, even in such a case, as described above,
Is invalid, the shutter does not operate in the opening or closing direction.

At the same time, the operation signal detection means 7 outputs a notification signal to the notification means 9 to externally notify that a remote control operation has been performed while touching an obstacle, and to store it in a storage unit as necessary (SP9). ). Thus, the operator carrying the remote control 5 can be notified that the remote control operation for opening and closing the shutter is invalid. By this external notification, the remote controller 5 can be informed that it is in a normal state where radio waves can be transmitted wirelessly, and that it is in a state where obstacle contact has been normally detected. That is, although the shutter cannot be opened and closed by the remote control operation, it can be notified that this is not based on the failure of the remote control 5. By the way, only the open / close switch of the remote controller 5 may be set as the above-described prohibition control object. In this case, the operation signal for stopping the remote controller 5 is valid, but no unexpected opening / closing is performed.

Thereafter, when the release key of the release means 10 is operated, the flag is reset, the output of the notification signal is stopped, and the notification from the notification means 9 is stopped. The release unit 10 is operated after confirming removal of an obstacle, and is provided near the control unit 3. This release means 10
May be configured to use any one of the switches of the operation unit 4. However, for example, if the switch is a stop switch, the shutter does not open and close even when operated.

In the above embodiment, the configuration in which the remote controller 5 is set as the object of the prohibition control has been described, but the operation unit 4 may be set. When the operation unit 4 is in a state where the operation unit 4 cannot be seen through a place away from the shutter or in the shade, even when the operation unit 4 is opened and closed when an obstacle is detected, unexpected opening and closing can be prohibited.

[0025]

According to the present invention, even if the opening / closing operation is performed by the operating means during the period when the sensing means detects an obstacle at the time of opening / closing the shutter, this is invalidated.
Unexpected opening and closing of the shutter can be prohibited. When the operating means is a remote control that is wirelessly operated from a remote location, the remote control operator may judge that the remote control has failed in the same state, but the control means receives a radio wave from the remote control operation. By operating the notification means, it is possible to externally notify that the remote control is normal and is in an obstacle contact state, and does not bother the remote control operator. Further, the control means can arbitrarily set specific operation switches of the wireless remote controller and the operation unit connected by wire as an object of prohibition control at the time of contact with an obstacle, and a shutter by these specific operation switches during the obstacle control period. Even if there is an opening and closing operation, opening and closing in the same direction can be prohibited.
