Description

  The present invention relates to a control device for an electric blind in which operations such as raising and lowering and rotation of a blind are performed by driving a drive unit, and more particularly, to a control device for an electric blind capable of saving energy.

  Conventionally, as a control device for an electric blind designed to save energy of this kind, there is one described in Japanese Patent Laid-Open No. 2000-181537 (Patent Document 1). In this control device, a light receiving device driven by the power of the solar cell, a drive source control circuit controlled and operated by a control signal and a power output from the light receiving device, a battery or a commercial AC power input and a power switch circuit And a power supply driving device. By the power of the solar cell, the light receiving device and the drive source control circuit are always kept in an energized state, and the light receiving device receives a remote control signal from an infrared light emitting remote controller having various control signal light emitting functions. A signal is sent to activate the drive source control circuit. The drive source control circuit turns on the power switch circuit of the power supply control device, supplies power from the commercial AC power supply or battery to the drive circuit and the drive source, drives the drive source, and does not output from the light receiving device In some cases, the power switch circuit is controlled to be turned off.

  In short, in this control device, when there is no control signal, that is, in the standby state, the light receiving device is always energized by the power of the solar cell, and when the control signal is output by remote operation, the light receiving device detects the signal. Thus, the drive source control circuit is operated to drive the drive source, which is a motor, using the commercial AC power supply or the battery, so that the commercial AC power supply or the battery is not consumed in the standby state. We are aiming for energy.

  However, such a control device using a solar cell has a high cost, and there is a problem that the device becomes large in order to secure sufficient electric power from the solar cell even at night or in fine weather. .

JP 2000-181537 A

  The problem to be solved by the present invention is to provide an electric blind control device that can save energy at a low cost and has good operability.

In order to solve the above-described problem, the invention described in claim 1 includes a control unit that controls a drive unit provided in the blind body, a transmission unit that sends a command signal by a user's operation , A receiving unit that receives the command signal and sends it to the control unit; and at least a power source that supplies power to the receiving unit, and the control unit drives the driving unit while the receiving unit receives the command signal. In the control device for the electric blind that drives and operates the shielding material,
While receiving the command signal, the receiving unit can intermittently accept the command signal from the transmitting unit, while continuously receiving the command signal for a predetermined time after receiving the command signal. It is characterized by doing.

The invention according to claim 2 is the one according to claim 1, wherein the control unit is

It is characterized by providing.

  According to a third aspect of the present invention, in the first or second aspect, the power source is a dry battery.

  According to the first and second aspects of the present invention, in the state where the normal receiving unit is waiting for the command signal from the transmitting unit, the power consumption can be saved in order to make the acceptable time intermittent. Thus, energy saving can be achieved at low cost. On the other hand, after receiving the command signal, in order to enable continuous reception of the command signal, if there is a command signal again immediately after the command signal stops, the reception is not time lag. The drive can respond quickly. That is, since the responsiveness is good when the user re-operates immediately after the operation once, a good operational feeling can be given.

  According to the invention described in claim 3, it is possible to reduce the consumption of the capacity of the dry battery and to prolong the service life.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The following embodiments do not limit the present invention.

  FIG. 1 is an overall schematic configuration diagram of an electric blind control device according to an embodiment of the present invention, and FIG. 2 is a block diagram thereof. In the figure, reference numeral 10 denotes a blind body, and a drive unit 14 for moving up and down or rotating the shielding member 12 of the blind body 10 is provided in the blind body 10. The drive unit 14 includes a motor drive circuit 42 and a motor 44.

  The control device for the electric blind includes a control unit 16 that can control the rotation of the motor 44 of the drive unit 14, a receiving unit 18 that receives a command signal, a transmitting unit 24 that transmits the command signal, a control unit 16, and a receiving unit. 18 and a power source 22 for supplying power to the drive unit 14. The control unit 16, the receiving unit 18, and the power source 22 are provided on the blind main body 10 side, and the transmission unit 24 is provided so as to be separable from the blind main body 10 in order to enable remote operation.

  The transmission unit 24 is appropriately provided with operation buttons 32 corresponding to “up”, “down” or “forward rotation of the shielding material” and “reverse rotation of the shielding material” (see FIG. 1), and receives an infrared command signal. An infrared light emitting diode 34 that emits light, a control circuit 36, and a power source 38 are incorporated (see FIG. 2).

  The receiving unit 18 includes an infrared light receiving diode 82 that receives infrared light. The receiving unit 18 is configured to send the received command signal to the control unit 16 and be supplied with power from the control unit 16.

  The control unit 16 can be composed of a microcomputer, and as a function realized by a program stored therein, power is intermittently supplied to the reception unit 18 and the reception unit 18 is intermittently supplied. The intermittent operation means 62 for activation, the continuous operation means 64 for continuously supplying power to the receiving unit 18 and continuously activating the receiving unit 18, and the input of the command signal from the receiving unit 18 are received. A command signal determining means 66 for determining whether or not it has been received, a time measuring means 68 for measuring a predetermined time, and a motor driving means 70 for outputting a drive signal for driving the motor.

  The power signal from the intermittent actuation means 62 or the continuous actuation means 64 is input to the input voltage port of the receiver 18 so that the receiver 18 is active.

  The drive signal from the motor drive means 70 is sent to the motor drive circuit 42, where it becomes a signal for causing the motor 44 to rotate forward and reverse.

  In the case of this example, the power source 22 is composed of a dry battery. Therefore, it is particularly desired to reduce power consumption and extend the use period. However, the present invention is not limited to this, and any other battery such as a commercial power supply or a solar battery can be used. Even in this case, it is desirable to suppress power consumption.

  The operation of the blind control apparatus configured as described above will be described with reference to the flowchart of FIG.

  The receiving unit 18 needs to be on standby so that the signal from the transmitting unit 24 can be received at any time. Normally, power is supplied to the receiver 18 by an intermittent signal from the intermittent operation means 62 such as the pulse signal shown in FIG. 4A (step S10 in FIG. 3), and the receiver 18 is intermittently operated. Active to reduce power consumption. In the example of FIG. 4A, the power consumption is halved by setting the duty ratio of the pulse signal to ½, and the cycle is about 0.5 seconds. The power consumption can be changed by changing the duty ratio. However, if the inactive time is set too long, the timing for receiving the command signal from the transmission unit 24 is delayed, so it is desirable to set an appropriate duty ratio.

  The command signal determination means 66 always determines whether there is a command signal from the receiving unit 18 (step S12). When the user operates the operation button 32 of the transmission unit 24 in order to move the shielding material 12 up and down or rotate, a command signal is transmitted from the transmission unit 24. When the command signal (FIG. 4B) from the transmission unit 24 is received by the reception unit 18 at an acceptable timing, the command signal is input to the control unit 16. If the determination result in step S12 of the designation signal determination means 66 is YES, it is determined whether the command signal is an increase command (forward rotation command) or a decrease command (reverse rotation command) (step S14). In the case of the ascending command (forward rotation command), the motor drive means 70 sends a motor forward rotation signal to the motor drive circuit 42 (step S16). In the case of a descending command (reverse rotation command), the motor drive signal 70 sends a motor reverse signal to the motor drive circuit 42 (step S18).

  Then, electric power is continuously supplied to the receiving unit 18 by the continuous signal from the continuous actuating means 64 (step S20), and the receiving unit 18 is continuously activated so that the command signal can be received. While the command signal is being input, step S12 and step S20 are repeated. Thus, once the command signal is received, the signal is continuously received, and the operation of the motor 44 is not interrupted. As long as the command signal is input, the shielding material 12 is continuously raised or lowered ( Or rotation) operation is performed.

  Next, when the command signal is not input or is stopped (NO in step S12), it is determined whether or not the motor 44 is operating (step S22). The data is sent to the motor drive circuit 42 (step S24). And the time measuring means 68 is reset and time measurement is started (step S25).

  In the next step S26, based on the count of the time measuring means 68, it is determined whether or not it is within a predetermined time after the command signal is stopped. If it is within the predetermined time, power is continuously supplied to the receiver 18 by a continuous signal from the continuous actuating means 64 (step S28), and the receiver 18 is continuously activated to accept a command signal. Make it possible. As a result, when there is a command signal again within a predetermined time after the command signal disappears, the command signal can be received without delay and the motor 44 can be operated. This is because the user tends to perform a re-operation for fine adjustment immediately after the operation. In this re-operation, since the blind responds quickly, it can give the user a good feeling of operation. The predetermined time can be, for example, 2 seconds to 30 seconds.

  In step S26, after a predetermined time has elapsed after the stop, the process returns to step S10 again, and intermittently monitoring the presence / absence of a command signal with an intermittent signal from the intermittent operation means 62 to save energy.

  According to the above operation, as shown in FIG. 4, when a command signal is input while waiting for a command signal and receiving an intermittent signal, the motor 44 and the blind body caused by the intermittent cycle are input. There is a possibility of occurrence of 10 operation deviations (FIG. 4A). However, once the motor 44 is operated and stopped, it is continuously accepted, so there is no deviation in the operation start even if the command signal is re-input (FIG. 4 (A)). Such re-input of the command signal is, for example, higher than the desired position when the shielding member 12 is raised, or when the shield material 12 is lowered or vice versa. For example, when the shield member 12 is moved down too much, or when the shield member 12 is rotated, the shield member 12 is moved in the opposite direction and correction is desired. In such a case, the user has a tendency to desire to make a quick correction, and if there is a deviation in the operation start, the operational feeling deteriorates. However, as shown in FIG. Therefore, the feeling of operation can be improved.

  In addition, when a command signal is input after the lapse of a predetermined period after the operation is stopped, an intermittent reception is made, and there is a possibility that a deviation of the operation start occurs (FIG. 4 (c)).

  In this way, energy saving can be achieved by accepting intermittently at normal times, so that even when the power source is a dry battery as in this embodiment, the consumption of the dry battery can be prevented, the life can be extended, and The operability can be maintained well.
