Abstract

PURPOSE:To get a machine to perform expected movement certainly, by driving a machine main body with a driving mode equivalent to the contents of memory until the state detection contents are reversed when the operation signal is received equivalent to the state detection contents, and then by driving the machine main body with the driving mode equivalent to the operation signal. CONSTITUTION:When a shutter is totally closed, if a stopping switch 38 is turned ON after an opening switch 36 is turned ON, then after a driving motor of a switching drive means 19 becomes 'open' and acts on the shutter toward opening, a stopping means 20 is driven to stop the shutter in a slightly opened state. At this moment, a limit switch 17 remains closed. Then, when a stopping switch 37 is turned ON, the means 19 becomes 'open' driving mode as the detected contents of a state detection means 21 is 'closed' and a state detection means 21 is 'opened'. When a limit switch 16 is closed and 17 is opened so that the detected contents of the means 21 becomes 'opened', the driving mode of the means 19 is switched to 'closed', acting on the shutter towards closing.

Description

[Detailed Description of the Invention] Industrial Application Field The present invention performs opening and closing operations by driving a motor.
This invention relates to a monitoring and control device for motor-driven automatic opening/closing devices such as electric shutters and electric blinds.

Conventional technology Conventionally, automatic opening/closing equipment that uses a motor to open and close is the third type.
The electric circuit is purchased as shown in the figure.

In FIG. 3, reference numeral 1 denotes an automatic opening/closing device main body (hereinafter referred to as the device main body), and 2 a mechatronic operating switch. These device main body 1 and operating switch 2 constitute an automatic opening/closing device 3. Reference numeral 4 denotes a single-phase, two-winding type motor, which performs forward and reverse operations depending on the function of a capacitor 6 inserted between the windings and which winding of the commercial power supply 6 is applied to using the operation switch 2. 7 is a first limit switch whose contact opens to stop the motor 4 when the motor 4 completes a predetermined forward (reverse) rotation operation (at 131J, the electric switch is fully open). 8 is the second limit switch (hereinafter referred to as 2nd L)
It is called S. ), when the motor 4 completes a predetermined reverse (forward) rotation operation (for example, when the electric shutter becomes fully closed), the contact opens and the motor 4 is stopped.

FIG. 4 is an operation mode diagram showing the operation of the conventional automatic opening/closing device 3. As shown in FIG. When the device body 1 is fully open, press the operation switch 2.
When the switch is set to ``CLOSE'', the device body 1 performs a closing operation, and after a while, the contact of the second LS8 opens and the device body 1 stops in the fully closed state.Next, when the operation switch 2 is set to ``OPEN'', The device main body 1 performs the opening operation from the fully closed state, but the second LS8 waits for a while after the device main body 1 starts the opening operation due to its own hysteresis (non-operating area) and the mechanical inertia of the device main body 1. After that (for example, when the shutter opens a little more than fully closed), its own contact closes.

Problems to be Solved by the Invention In the above-mentioned conventional automatic opening/closing device 3, the device main body 1 is opened from the fully closed state using the operating switch 2, and then the second LS is opened.
Until the contact point 8 closes (the shaded area in Fig. 4), set the operation switch 2 to ``stop'' to stop the opening operation of the device body 1, and then turn the operation switch 2 to ``close'' again to close the device body 1. Even if an attempt is made to close the device, the commercial power 6 is not applied to the motor 4 because the contact of the second LS 8 is open, and the device body 1 remains stopped. This poses a problem in that it may lead to the user thinking that the device is malfunctioning, and that the reliability of operation of the device body 1 is lowered.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a monitoring and control device that can reliably cause a motor-driven automatic opening/closing device to perform desired operations.

Operation The present invention allows the device main body to perform desired operations reliably due to the above-described configuration.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is an electric circuit diagram showing a motor-driven automatic opening/closing device main body (hereinafter referred to as the device main body) and its monitoring and control device, and shows the case where an electric Nyatta main body is used as the device main body. A motor 12 has two windings and operates in forward and reverse directions to open and close a shutter (not shown). A capacitor 1 is connected between one end of the first winding 121L and the second winding 12b.
3 are connected, and the other end of each is connected to one end 141L of the commercial power supply 14 as a common end, and when the commercial power supply 14 is connected to the first winding 12&, the first winding 121L
is the main winding, and the second winding 12b is connected to the commercial power supply via the capacitor 13, so it functions as a so-called auxiliary winding, and the motor 12 rotates in the normal direction to move the shutter in the direction of opening.

On the other hand, when the commercial power supply 14 is connected to the second winding 12b,
This time, the second winding 12b becomes the main winding and the first winding 12a becomes the auxiliary winding, so the motor 12 performs a reverse operation and moves the shutter in the closing direction.

16, 16 are the first and second windings 12a, 1 of the motor 12

and a second limit switch (hereinafter referred to as 2nd LS).
Then, when the motor 12 completes the predetermined forward rotation operation and the shutter changes from the opening operation to a completely open state (fully open), the first
The contact of LS15 is opened to cut off the current, stop the normal rotation of the motor 12, and prevent the shutter from opening any further. Further, when the motor 12 completes a predetermined reverse operation and the shutter changes from the closing operation to a completely closed state (fully closed), the contact of the second LS 16 opens and the motor 12
The reverse rotation of the shutter is stopped, and the shutter is prevented from closing any further. Furthermore, when the shutter is fully closed and the motor 12 is rotated forward to open the shutter, the second LS 16 prevents the shutter from opening due to its own hysteresis (non-operating area) and the operating inertia of the device body 11. The contact closes a while after it starts.

17 is the third limit switch (
Hereinafter, it will be referred to as the 3rd LS. ), the operation of that contact is the second L.
Contrary to S16, it closes when the shower head is fully closed. That is, when the shutter is in the fully closed state and the motor 12 is rotated in the forward direction to open the shutter, the contact of the third LS 17 opens a while after the shutter starts opening.

Reference numeral 18 denotes a monitoring and control device for driving and monitoring the device main body 11, which includes an opening/closing driving means 19 for opening, closing, and driving the device main body 11, a stopping means 20 for stopping the driving of the device main body 11, and a monitoring control device for controlling the opening/closing state of the device main body 11. State detection means 21 for detecting

The opening/closing and driving means 19 is composed of an opening/closing relay 28 consisting of an opening/closing relay coil 26 and a single-pole, double-throw switching contact 27, and a first transistor 29 that energizes the opening/closing relay coil 26 in response to a command from the microcomputer 24. Means 2o is a stop relay 32 consisting of a stop relay coil 30 and a normally closed stop contact 31, and a stop relay coil 30 connected to a microcomputer 24.
The normally open contact 27 of the switching contact 27 of the opening/closing relay 28 is composed of a second transistor 33, etc., which is excited in response to a command from the switching relay 28. L is connected to the first LS15 of the device body 11, the normally closed contact 27b is connected to the second L516, the common terminal 270 is connected to one end of the stop contact 31 of the stop relay 32, and the normally closed contact 27b is connected to the stop contact 31 of the stop relay 32.
The other ends are respectively connected to the other ends 14b of the commercial power source 14.

The state detection means 21 includes first and second resistors 3 connected in series.
4.36, one end of the first resistor 34 is connected to the third LS of the device main body 11 as an input terminal of the state detection means 21.
It is connected to one end of the third LSI 7.
The other end is connected to VCC, which is the + pole of the DC power supply 26. On the other hand, the connection point between the other end of the first resistor 34 and one end of the second resistor 36 is connected to the microcomputer 2 as an output of the state detection means 21.
It is input to the state detection input terminal 241L of No. 4. Also, the second
The other end of the resistor 35 is connected to GND, which is one pole of the DC power supply.

When the contact of the third LSI 7 of the device main body 11 is closed with the shutter fully closed or slightly opened, VCC is applied to the state detecting means 21.
The detection content is "closed", and the voltage rHJ obtained by dividing this VCO by the first and second resistors 34 and 36 is input to the state detection input terminal 24 & of the microcomputer 24.On the other hand, when the shutter is in a state other than the above, At times, the contact of the third LS 17 is open, so the state detection means 21 is disconnected from the VCO and the detection content is "open", and the state detection input terminal 24a of the microcomputer 24 becomes rJ, which has the same potential as GND.

The operating means 23 is an open switch 36. It is composed of a close switch 37 and a stop switch 38, and these switches 38-

The storage means 22 of the microcomputer 24 stores that the detection contents of the state detection means 21 are "closed" (=the state detection input terminal 24 of the microcomputer 24).
! L voltage is "H"), and the opening/closing and driving means 19 is "closed" 2. When the driving mode is set (= the opening/closing relay coil 26 is not excited and the common terminal 270 of the switching contact 27 is the normally closed contact 27b). ), the state detection means 21
In other words, even if the detection content of the state detection means 21 is "closed", when the opening/closing drive means 19 is in the "open" driving mode (=the opening/closing relay coil 26 is not energized). , the common terminal 270 of the switching contact 27 is the normally open contact 271
When the state detection means 21 is connected to L), the storage means 22 stores "°1 open" and "2", contrary to the detection content of the state detection means 21. Also, when the detection content of the state detection means 21 is "open". At times, the storage means 22 stores "open" in the opening/closing 7 regardless of the driving mode of the moving means 19.

When the open switch 36 is pressed, an opening operation signal is input to the microcomputer 24, and the microcomputer 24 sets the opening/closing drive means 19 to the "open" drive mode, stops driving the stop means 20, and closes the stop contact 31. , the device main body 11 is opened.

When the close switch 37 is pressed, a close operation signal is input to the microcomputer 24 to cause the device main body 11 to perform a closing operation, and the operating leg is as follows.

1. When the detection content of the state detection means 21 is '°open'2, the opening/closing drive means 19 is set to the 'closed' driving mode, and the driving of the stopping means 2o is stopped, and its stop contact 31 is closed;
The device main body 11 is operated to close.

2. When the detection content of the state detection means 21 is "closed" and the memory content of the storage means 22 is "open", the drive of the stop means 2o is stopped, the stop contact 31 thereof is closed, and the state detection means 21 is stopped. Detection content is “closed” to 1
The opening/closing driving means 19 is set to the ``1 open'' driving mode corresponding to the stored content of the storage means 22 ``open'' until the device body 11 is opened, and then the opening/closing driving means 19 is operated in the ``1 open'' drive mode corresponding to the closing operation signal. mode and closes the main body 11 of the device.

3. When the memory content of the storage means 22 is "Closed" At this time, the opening/closing drive means 19 is already in the "Closed" drive mode, so this "Closed" drive mode is maintained and the stop means is 2oI7) Stop driving.

When the stop switch 38 is pressed, a stop operation signal is input to the microcomputer 24, and the microcomputer 24 uses this stop operation signal to drive the stop means 2o and energize the stop relay coil 3o, so the stop contact 31 is opened and the device is closed. The opening/closing operation of the main body 11 is stopped. The opening/closing and driving means 19 is not affected by this stop operation signal and remains in the previous drive mode (°'Open').
or maintain the "closed" drive mode).

Next, the operation of the configuration of this embodiment will be explained with reference to FIG. 1 and FIG. 2 showing the operation mode.

Now, let's consider changing the shutter from a fully open state to a completely closed state, then opening the shutter a little to stop it, and then completely closing the shutter again.

Since the shutter is in the fully open state, the drive mode of the opening/closing drive means 19 is "t", and the second LS1 e in the device main body 11 is
is closed, and the contact of the third LS17 is open, so the detection content of the state detection means 21 is ``Open'', and therefore the stored content of the storage means 22 is ``Open''. (Operating mode ■) To close the shutter When the close switch 37 is pressed, the drive mode of the opening/closing drive means 19 becomes "closed" and the shutter is operated in the closing direction, but since the contacts of the third LSI 7 remain open, the detection contents of the state detection means 21 are Both the storage contents of the storage means 22 remain open.

(Operating mode ■) Then, after a while, when the shutter becomes fully closed, the contact of the second LS16 opens and the device body 1 opens.
Stop the operation of step 1. At this time, the contact of the third Ls 17 is closed, so the detection content of the state detection means 21 is "1 closed", and the drive mode of the open/close drive means 19 is "9 closed".
Therefore, the memory contents of the storage means 22 are 'closed'.
becomes. (Operating mode 0) Next, in order to open the shutter slightly from the fully closed state and stop it, press the open switch 36 and then press the stop switch 38, and the opening/closing driving means 19
The drive mode is ``Open''.After the shutter is moved in the direction of opening, the stopping means 2o is driven to stop the shutter in a slightly open state.At this time, the 3rd LS
Since the contact point of I7 is still closed, the detection content of the state detection means 21 is 'closed', but the opening/closing drive means 19
Since the drive mode of is open "', the stored contents of the storage means 22 are the same as open "'. (Operating mode ■) Next, when the close switch 37 is pressed to change the shutter from the slightly open state to the fully closed state again, the detection content of the state detection means 21 is "closed" and the memory means 22 stores it. Since the content is "open", the opening/closing driving means 19 becomes the "open" driving mode, and the driving of the stopping means 20 is stopped.
Move the vine in the direction of opening. And the 3rd L
When the contact of the SI 7 opens (the contact of the second LS16 closes) and the detection content of the state detection means 21 changes from "closed" to "°open", the drive mode of the opening/closing drive means 19 is switched to "°closed". to move the shutter in the direction of closing.

(Operating mode ■) After a while, the shutter becomes fully closed and the 3rd LS
The contact point 17 is closed, and the detected content of the state detection means 21 becomes ``1 closed'', and the stored content of the storage means 22 becomes ``1 closed''. (Operating mode [F]) From the above, the closing operation signal was input (closing switch 37 was pressed) while the shutter was stopped slightly open from the fully closed state (the contact of the second LS16 was open). At times, the shutter can be closed reliably.

Effects of the Invention As is clear from the above explanation, according to the present invention, the drive mode of the opening/closing drive means for driving the opening/closing of the device body and the detection content of the state detection means for detecting the opening/closing state of the device body do not match, and the device When the main body is stopped and an operation signal corresponding to the detected content of the condition detecting means is received, the opening/closing drive means operates in the drive mode corresponding to the stored content of the storage means until the detected content of the condition detecting means is reversed. Since the main body of the device is driven in the drive mode corresponding to the operation signal and then the main body of the device is driven in a drive mode corresponding to the operation signal, it is possible to perform the desired operation reliably.
