Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electric shutter device in which a motor drives a shutter body, such as a shutter door, a blind, a curtain, etc., to open and close.

[Conventional technology]

Conventionally, the opening/closing switch and its opening/closing control device for electric shutters installed in general houses are installed in the room where the shutter body is placed, and the opening/closing operation is performed by visually confirming the opening/closing status of the shutter body. However, with the development of centrally managed housekeeping systems, remote control pushbutton switches have been installed so that opening and closing can be controlled from a remote location away from the room.

[Problem that the invention seeks to solve]

However, in the past, there were three remote control switches: a push-button switch for closing the shutter, a push-button switch for opening the shutter, and a push-button stop switch for stopping the opening/closing operation of the shutter.
Since there are two switches, a wire is required to send the input and output to the shutter opening/closing control device for each switch, and the length of this wire is considerably longer than that required for the hand-operated switch, so the wire cost and There was a problem that the wiring cost was high.

[Purpose of the invention]

The present invention was made to solve the above problem, and compared to the conventional method, the number of electric wires for remote control can be reduced.
The object is to obtain an electric shutter device that can reduce the price.

[Means to solve the problem]

In order to achieve the above object, the present invention uses one remote-controlled pushbutton switch, and the shutter opening/closing control section is provided with a condition monitoring section that constantly monitors the open/closed state of the shutter. When receiving the closing output of the pushbutton switch, it determines the intention to close the remote control pushbutton switch and generates a shutter opening/closing and stop command signal.

〔Example〕

The figure is a block diagram showing one embodiment of the present invention. In the figure, 1 is an electric shutter, and 2 is a shutter body consisting of an electric shutter shutter. It is attached so as to be wound up, and is configured to move up and down in the vertical direction while being guided by guide rails 6.6 disposed on both sides. The winding shaft 5 is driven by a drive motor 9 via a Cheno wheel 7 and a Cheno wheel 8 .

Reference numeral 10 denotes a shutter closing detection switch (for example, a limit switch), which sends out a shutter closing detection signal LC turned on by a driver 11 fixed to the shutter body 2 when the shutter body 2 is completely closed. Reference numeral 12 denotes a shutter open detection switch (for example, a limit switch), which detects when the shutter body 2 is fully opened.
A shutter open detection signal LO, which is turned on by a driver 13 fixed to the shutter, is sent out.

Reference numeral 14 denotes a hand control panel, which is provided inside the chamber in which the shutter body 2 is installed, and has a close pushbutton switch 14C, an open pushbutton switch 140, a stop pushbutton switch 14S, and a close pushbutton switch 14C. When the switch 14C is pressed, the shutter close command signal C is sent, when the open button switch 140 is pressed, the shutter open command signal O is sent, and when the stop button switch 14S is pressed, the shutter stop command signal S is sent to control the opening and closing of the shutter. 20.

Reference numeral 15 denotes a remote control panel section, which is provided in a separate room from the above-mentioned room, and includes - remote control pushbutton switches 16, a close indicator lamp 17C, and a close indicator lamp 17.
It has 0. The remote control pushbutton switch 16 supplies the closing output generated by its closing to the X-shutter opening/closing control section 20.

The shutter opening/closing control section 20 is constituted by a microcomputer, and is shown in functional diagram form in the figure. In the shutter opening/closing control section 2°, the shutter close command signal C is guided to a forward rotation command circuit section 21, and the shutter open command signal 0 is guided to a reverse rotation command circuit section 22. When the forward rotation command circuit section 21 receives the shutter closing command signal C, it sends out a forward rotation command signal to the drive circuit section 30 of the drive motor 9, and when it receives the shutter closing detection signal LC, it sends out a forward rotation stop command signal. When the drive circuit section 30 receives this forward rotation command signal, it supplies a forward current to the drive motor 9 to drive the drive motor 9 in the downward direction of the shutter body 2, and when it receives the forward rotation stop command signal, it supplies a forward current to the drive motor 9 to drive the drive motor 9 in the downward direction of the shutter body 2. The current supply is cut off to stop the rotation of the drive motor 9. When the reverse rotation command circuit section 22 receives the shutter open command signal O, it sends a reverse rotation command signal to the drive circuit section 30 of the drive motor 9, and when it receives the shutter open detection signal LC, it sends out a reverse rotation stop command signal. When the drive circuit unit 30 receives this reverse rotation command signal, it supplies a reverse direction current to the drive motor 9 to drive the drive motor 9 in the direction of winding up the shutter body 2, and when it receives the reverse rotation stop command signal, it supplies a reverse direction current to the drive motor 9, and when it receives the reverse rotation stop command signal, it drives the drive motor 9 in the reverse direction. The current supply is cut off to stop the rotation of the drive motor 9. The forward rotation command circuit section 21 and the reverse rotation command circuit section 22 are further supplied with a shutter stop command signal S, and upon receiving this signal S, generate a forward rotation stop command signal and a reverse rotation command signal, respectively.

The shutter opening/closing control section 2o further includes a state monitoring section 23. The state monitoring unit 23 includes a first determination unit 23A,
It includes a second determining section 23B and a third determining section 23C. The first determination unit 23A is a shutter open detection switch 1
o is guided and the shutter open detection signal LO is input, and when the input signal from the remote control pushbutton switch 16 is received, the shutter open command signal O is sent to the forward rotation command circuit section 21. . When the second determination unit 23B receives the closing output of the remote control pushbutton switch 16 while the output of the shutter closing detection switch 12 is guided and the shutter closing calibration signal LC is input, the second determination unit 23B determines whether the reverse rotation command circuit A shutter close command signal 0 is sent to the section 22. When the third determination unit 23C receives the closing output of the remote control pushbutton switch 16 in a state where neither the shutter close detection signal LC nor the shutter open detection signal LO is generated, the forward rotation command circuit unit 21 and the reverse rotation command A shutter stop command signal S is supplied to the forward rotation command circuit section 21 and the reverse rotation command circuit section 22 on the condition that the circuit section 22 outputs a forward rotation command signal and a reverse rotation command signal, respectively, and
The shutter closing command signal C is supplied to the forward rotation command circuit section 21 on the condition that both the forward rotation command circuit section 21 and the reverse rotation command circuit section 22 are not outputting.

The shutter opening/closing control section 20 further includes a lamp lighting control section 24 . The lamp lighting control section 24 includes a static lighting circuit 25, a slow flickering lighting circuit 26, and a normal flickering lighting circuit 27. Stationary lighting circuit 25
are shutter closed detection signal LC and shutter open detection signal L
O is led, and if the former is input, the close indicator lamp 1
7C is lit in a static state, and when the latter is input, the close indicator lamp 170 is lit in a static state. slow flicker circuit 2
5, a forward rotation command signal output from the forward rotation command circuit section 21 and a reverse rotation command signal output from the reverse rotation command circuit 22 are guided, and when the former is input, the close indicator lamp 17C is slowly flickered. and when the latter is input, the close indicator lamp 170 is slowly flickered. Normally, the flicker lighting circuit 26 receives an abnormality detection signal from an abnormality detection device (not shown) and displays a closed display when receiving the abnormality detection signal.
The lamp 17G and the close indicator lamp 170 are flickered on.

In this configuration, whether or not the shutter body 2 is open/closed and in operation is determined by the shutter body.

You can access the remote control panel 15 without going to the room where 2 is installed.
It can be known from the presence or absence of lighting of the closed indicator lamp 170 and the closed indicator lamp 17C, and the flicker lighting mode. For example, at night, the close indicator lamp 170 is lit stationary (when the shutter body 2 is completely opened). If you want to close the shutter body 2 (since the shutter body 2 is closed), turn on the remote control pushbutton switch 16, and the first determination section 23A will generate the shutter shutter 1 close command signal C, so that the drive circuit section 30
supplies a positive direction current to the drive motor 9 and the shutter body 2
is lowered, and the close indicator lamp 17C slowly flickers on until it is completely lowered. If it becomes necessary to stop the closing operation of the shutter body 2 during this lowering, the same remote control pushbutton switch 1 is turned on, and the third determination section 23C generates a shutter stop command signal S. Therefore, the drive motor 9 stops rotating and the lowering operation of the shutter body 2 stops. Also, at night, since both the close indicator lamp 17C and the close indicator lamp 170 are off (since the shutter body 2 is in a half-open state), if you want to close the shutter body 2, use the remote control pushbutton switch 16. For example, in the daytime, if you notice that the shutter body 2 is closed because the closed indicator lamp 17C is lit and you want to open the shutter body 2, you can use the remote control. When the pushbutton switch 16 is turned on, the second determination section 23B generates the shutter opening command signal O, so the drive motor 9 rotates in the reverse direction and the shutter body 2 is wound up.

In this way, in this embodiment, the state monitoring unit 23 always
The state monitoring unit 23 monitors the opening/closing state and operating state of the shutter body 2, and the state monitoring unit 23 is connected to the remote control pushbutton switch 1.
6, the shutter body 2 determines the intention to press the remote control pushbutton switch 16 from the state of the shutter body 2 and generates a signal to open/close the shutter body or stop its operation. The number of signal lines required for remote control is 1/3 that of the conventional case, which has three remote control pushbutton switches for opening, closing, and stopping.

The present invention is not limited to the above-mentioned embodiments, and various embodiments are possible. For example, the shutter body may be a rain door,
It may be blinds, curtains, etc.

〔Effect of the invention〕

According to the present invention, with one remote control pushbutton switch,
Since the shutter body can be controlled to open, close, and stop, the number of signal lines for transmitting signals for remote control is reduced to 1/3 compared to conventional methods, which reduces the cost of electric wires and makes wiring work easier. , the price of the electric shutter can be reduced.
