Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a remote control system for electric blinds, and more specifically, a system for controlling blinds using a plurality of different control methods via the same transmitter/receiver. It is related to the device.

[Prior art] A remote control device for blinds is disclosed in Utility Model Application No. 17299/1986.
No. 5, No. 60-172996, etc.

The control device includes a receiver for each of the blinds that can be opened and closed, and uses a separate transmitter to remotely control each blind independently. However, although the known device can control multiple blinds using the same control method, the same device cannot control blinds using different control methods. Therefore, a different remote control device is used for each blind control method. was necessary.

[Problems to be solved by the invention] It is not uncommon for two or more types of electric blinds to be installed in the same room, but the control methods for electric blinds differ depending on the type. For example, Venetian blinds, roll blinds, etc. There are only two operating switches, one for lowering and one for lowering.While the operating switch is pressed, the motor rotates to raise or lower the blind, and when the operating switch is released, the motor immediately stops. Curtains, vertical blinds, etc. are equipped with three operation switches for opening, closing, and stopping, and when the open or close operation switch is pressed, the motor rotates whether the switch is held down or released after being pressed. The motor will stop when you press the stop operation switch.

Since it is cumbersome to use a separate remote control device for each blind with a different control method in the same room, there has been a need for a remote device that can operate blinds with different control methods using a single control device.

The present invention has been made in order to meet the above needs,
The aim is to provide a single device that can remotely control electric blinds with different control methods.

[Means for Solving the Problems] In order to achieve the above object, the features of the present invention include the following:
As shown in FIG. 1, there is a receiver 20 including a control circuit 22 that turns on and off the relays RD, RU, and R3 of the drive circuit 2B of the motor M of each blind, and a single transmitter lO that sends a signal to the receiver. A one-chip microcomputer IC that is selected by a specific selection signal transmitted by the transmitter 10 and then performs predetermined control by an operation signal.
2 is provided in the control circuit 22. The one-chip microcomputer IC2 has a program that enters the operating state according to each selection signal sent by the transmitter, and a program that turns each relay on and off according to each braking method.
The program to be executed by the one-chip microcomputer can be selected in advance.

[Operation] The transmitter emits a selection signal to select or cancel a particular blind or all blinds, and an operation signal to direct the operation of the blinds. Receiver 2 for each blind
0 receives the signal transmitted by the transmitter IO and inputs it to the one-chip microcomputer IC2. The one-chip microcomputer IC2 becomes activated when a preselected selection signal is input.

Then, when an operation signal is input, the relay of the motor drive circuit is controlled as set in advance.
In the case of a roll blind, the relay is turned on while the operating signal to rotate the motor is being input, and when the signal is interrupted, the relay is turned off. In the case of a curtain, when an operating signal to rotate the motor is input, the relay is turned on, and even if that signal is interrupted, the relay is not turned off, and when an operating signal to stop the motor is input, the relay is turned on. Turn off.

[Example] The apparatus of the present invention will be explained based on embodiments shown in the drawings.

As shown in FIG. 1, the apparatus of the invention consists of a hand-held transmitter IO and a receiver 20 installed in each blind. Transmitter! 0 is housed in a handheld case 11, as shown in FIG. An operation key 12 and a light emitting element 13 for displaying transmission are provided on the surface of the case 11, and a window 14 for emitting infrared rays is provided on the end face. transmitter lO
is one-chip microcomputer IC1 and key matrix MX
I, one oscillation element OSL, and an infrared light emitting element LEI,
It consists of a transmitting circuit 15 whose power source is a dry battery. Transmitter 10
The operation key 12 corresponds to the key matrix MXI, and when the operation key 12 is pressed, the infrared light emitting element LEI emits an infrared pulse code corresponding to the operation key 12 either once or continuously. The operation keys 12 consist of a selection key for specifying a blind and an operation key.The selection keys include an all key for selecting a blind number and a clear key for canceling the designation, and the operation keys are for raising (or opening) and lowering (or closing). ), and stop.

The receiver 20 is a photodiode PN that receives infrared light.
2, and an AM-F that amplifies the signal of the photodiode.
a one-chip microcomputer IC2 that receives signals from the receiving circuit, and a dip switch D that is connected to the one-chip microcomputer and regulates its operation.
W2, three photocouplers PC21, PC22, and PC23 that take out the output of the one-chip microcomputer IC2, and a light emitting element LE2 that indicates the status of the one-chip microcomputer IC2.
Relay coils CRU, CHD, which are excited by the conduction of photocoupler PC21, PC22, PC23,
It consists of a control circuit 22 including CR3.

As shown in Figure 3, there are usually two control systems for roll blinds: an open switch OP and a close switch CL.
While pressing the open switch OP or the close switch CL, the motor M rotates in the upward or downward direction of the screen,
The motor M stops when the limit switch Ll or L2 is turned off or when the switch is stopped being pressed. Normally open relays RU and RD are connected in place of the open and close switches OF and CL. In addition, instead of directly opening and closing the motor drive circuit with the open and close switch, as shown in Fig. 6, a key matrix MX2 is connected to the one-chip microcomputer lc2 of the control circuit 22, and the key matrix is opened and closed in the switch box. It may also be operated with a close switch.

As shown in Figure 4, the curtain curtain control method is usually
There are three switches: up switch UP, down switch DN, and stop switch ST. When you push up switch UP or down switch DN, it is self-held by its relay R1 or R2 and relay coil R1 or R2, and limit switch Ll or L2 turns off or stop switch ST
The motor M continues to rotate in the direction of raising or lowering the curtain until is pressed. Relays RS and RD are connected in parallel to the switches UP and DN, and relay RS is connected in series to the stop switch ST.

The dipski DW2 of the receiver 20 of each blind is 8
If the total number of blinds is 16 or less, the first four correspond to the number keys of the transmitter, and the fifth key corresponds to the program of the control method for each blind.

Curtains etc. tend to cover the switch box, so
As shown in Figure 5, the reception@20 is sent to the switch box 3.
It is provided at a position that is easy to see near the main body 40 and away from the main body 40. Although the switch box 30 of a roll blind or the like is installed near the main body 40, the front side is not covered.
It is preferable to incorporate the receiver 20 into the switch box 30. In either case, the power source is ACLo which enters the main body 40.
Use oV or 24V DC which is a step-down rectification of oV.

Next, remote control of blinds using the device of the present invention will be explained. Turn on the power of the transmitter 41110, turn the infrared window 14 toward the blind, and then press the individual selection key or - pattern selection key among the operation keys 22.The infrared pulse code corresponding to the pressed key is displayed. is an infrared element LE
Continuous transmission from I.

If you turn on and off in advance the four depth switches DW2 from the left of the receiver 20 provided for each blind, and match the number (binary) displayed thereby with the number of the selection key on the transmitter 10, the transmitter When the same numbered key of the 10 operation keys 22 is pressed, the receiver 20 receives an infrared pulse code transmitted from the transmitter 10.
The one-chip microcomputer IC2 enters the operating state, and the light emitting element L
Turn on ED2.

Next, when any one of the three operation keys of up, down, and stop on the operating section 22 of the transmitter 10 is pressed, an infrared pulse code corresponding to the pressed key is transmitted from the transmitter IO. When this signal is received by the receiver 920 of the operating blind, the one-chip microcomputer IC2 switches any one of the three photocouplers PC21, PC22, and PC23 according to the signal to turn on/off the fifth key of the dip switch DW. conduction according to a preselected program. When the photocoupler PC21 becomes conductive, the relay coil CRU is excited and the relay RU is turned on, so that the motor M rotates in the direction of raising or opening the blind. When the photocoupler PC22 becomes conductive, the relay coil CHD is excited and the relay RD is turned on, so that the motor M rotates in the direction of lowering or closing the blind. Photocoupler PC23
When becomes conductive, relay coil CR5 is energized, relay RS is turned off, and motor M is cut off from current and stopped.

When the fifth key of the dip switch DW of the receiver 20 is turned on, the one-chip microcomputer IC2 raises, lowers,
Execute the same control program as the control method using the three stop switches. That is, once the up key or down key of the transmitter IO is pressed to rotate the motor M, the motor M continues to rotate unless the stop key is pressed next, except when the upper and lower limit switches L1 and L2 are opened. When the fifth key of the dip switch DW is turned off, the one-chip microcomputer IC2 executes the same control program as the control method using the two open and close switches. That is,
An infrared pulse code signal corresponding to the up key or down key of the transmitter 10 is continuously transmitted, and the signal is transmitted to the receiver 2.
Motor M rotates while 0 is receiving, but sending @1
When the 0 up key or down key is released to interrupt the infrared pulse code signal, the photocoupler PC21 or PC2
2 becomes non-conductive, relays RU and RD are turned off, and rotation of motor M stops. In this case, since the relay coil CR5 is not used, it may be omitted as shown in FIG.

[Effects of the Invention] As mentioned above, the device of the present invention differs from conventional devices that can only control the same type of control, in that the device uses a control method in which the motor rotates while the switch is held down and stops when the switch is released. Roller blinds also have the excellent effect of being able to be remotely controlled with the same transmitter/receiver even with curtains that have a control system in which the motor rotates when the up or down switch is pressed, and the motor stops when the stop switch is pressed.
