Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control device provided in various home electric appliances such as various one-way or two-way communication devices, sunlight lighting systems, air conditioners and the like.

[0002]

2. Description of the Related Art Generally, a device provided at a high position or a remote position is provided with a remote control device, and can be remotely operated using a wireless transmission medium such as an infrared ray or a wired transmission medium such as a signal cable. It is possible. Many of today's remote control devices employ a wireless (infrared) method.

[0003] The remote control device includes a portable operation terminal for transmitting an infrared remote control signal, and a receiver provided in a device to be controlled, and the remote control signal received by the receiver is decoded by a decoder. It is sent to the control device of the device to be controlled.

[0004]

In the above-mentioned conventional remote control device, the receiver is always supplied with power to receive a remote control signal transmitted from the remote control device, and stands by in a so-called ON state. Therefore, there is a problem that power consumption in the receiver is large.

It is an object of the present invention to provide a remote control device capable of reducing power consumption.

[0006]

According to an aspect of the present invention, there is provided a remote control apparatus having a transmitter and a receiver for transmitting and receiving a remote control signal. A means for repeatedly transmitting the same remote control signal,
The receiver has an intermittent operation circuit for intermittently turning on and off the receiver.

According to the present invention, the power consumption is suppressed because the receiver is intermittently turned on and off by the intermittent operation circuit. However, if the transmitter transmits a remote control signal while the receiver is off, the receiver may not receive the signal.However, the remote control signal of the same content is repeatedly transmitted from the transmitter, so It becomes possible to receive.

[0008]

Next, a preferred embodiment of the present invention will be described with reference to the drawings.

This embodiment discloses an example in which the present invention is applied to a remote control device of an active solar lighting system.

FIG. 1 shows the principle of daylighting of the daylighting system, and FIG. 2 shows an example of a daylighting window viewed from the indoor side.

As shown in FIG. 1, the daylighting system 10 comprises:
It is attached to the skylight portion 12 of the house and guides light from the sun 14 into the room 16. An automatic sun tracking device 18 including a prism is provided in the daylighting system 10, and the light from the sun 14 can be always guided to the room 16 in accordance with the movement of the sun 14 by the automatic sun tracking device 18. Reference numeral 20 denotes a dome, and reference numeral 22 denotes a light distribution plate.

FIG. 2 is a perspective view of the daylighting system 10 as viewed from the bottom side (ie, the room 16 side). A receiving unit 26 is provided on the frame 24 on the bottom surface of the lighting system 10, and the receiving unit 26 receives a remote control signal from a transmitter 28.

FIG. 3 shows a block circuit of a remote control device according to this embodiment. In FIG.
The remote control signal 30a from the transmitter 30 is
Received by receiver 32. Reference numeral 34 denotes a microcomputer. The microcomputer 34 supplies an intermittent operation signal 34a to a switching element (transistor) 36 to turn on and off the switching element 36 intermittently, whereby power is intermittently supplied to the receiver 32. The receiver 32 intermittently turns on and off.

The transmitter 30 repeatedly transmits the same remote control signal so that the signal is transmitted at least once while the receiver 32 is on.

Next, the operation of the remote control device according to this embodiment will be described with reference to the block circuit of FIG. 3 and the waveforms of FIG.

FIG. 4 shows the state of the receiver (ON state and OFF state) and the remote control signal transmitted from the transmitter. The transmitter 30 repeatedly transmits the same remote control signals A, B, C, and D to the receiver 32.
Is in the ON state, the receiver 32 can receive at least one of the remote control signals A, B, C, D〜.

That is, since the data of the remote control signal A is transmitted while the leading end portion thereof is in the OFF state of the receiver 32, the data of the remote control signal A cannot be detected by the reader unit, and the reception failure occurs. Becomes
However, the reception of the remote control signal B is successful because all the data is transmitted while the receiver 32 is on. Since the data of the remote control signals C and D are transmitted while the receiver 32 is in the OFF state, the reception fails, but the purpose has been achieved because the remote control signal B has already been received. Here, the data of the same signals A, B, C, and D is (rear part No.) + (Company coat No.) + (Product coat No.) + (Data 1) + (data 2) ... + (checksum) ) As one claim.

As shown in FIG. 4, the receiver 32 is intermittently turned on and off, so that power consumption can be reduced while the receiver 32 is off. At this time, since the same remote control signal is repeatedly transmitted from the transmitter 30, the remote control signal is always received by the receiver 32 when the receiver is on.

Next, FIGS. 5 to 8 show detailed examples of the block circuit of FIG.

In FIG. 5, a receiver 38 receives an infrared remote control signal 40 from a remote controller and supplies a received signal 42 to a microcomputer 44. The receiver 38
The microcomputer 44 receives the power from the power supply 46-1 via the switching element 48, and
Receive power from 2 The microcomputer 44 supplies the intermittent operation signal 50 to the switching element 48 to intermittently turn the switching element 48 on and off, and supplies the power from the power supply 46-1 to the receiver 38 intermittently. The device 38 is intermittently turned on and off.

FIG. 6 shows a modification of the circuit of FIG. In this embodiment, the oscillation circuit 52 that receives power from the supply 46-3 supplies the intermittent operation signal 50 to the switching element 48.

FIG. 7 shows another modification of the circuit of FIG.
In this embodiment, the received signal 42 from the receiver 38
Is once supplied to the sub-microcomputer 54, and the sub-microcomputer 54 supplies only the normal signal 56 of the received signal 42 to the microcomputer 44. The sub-microcomputer 54 receives power from the power supply 46-4 and supplies an intermittent operation signal 50 to the switching element 48.

FIG. 8 shows still another modification of the circuit of FIG. In this embodiment, the circuit of FIG. 6 and the circuit of FIG. 7 are combined. That is, the power supply 46-3
The oscillation circuit 52 that receives power from the
Is supplied to the switching element 48 and receives the power from the power supply 46-4.
Of the received signal 42 from the microcomputer 44 is supplied to the microcomputer 44.

The current consumption of the receiver 38 is several mA, and the current consumption of the oscillation circuit 52 is about several μA. The current consumption of the microcomputer 44 varies variously depending on the operation state and the like, but is several tens mA during normal operation, and several tens mA during standby.
It is about 0 μA.

In the circuits shown in FIGS. 7 and 8, the receiver 38 frequently operates when noise is applied to the receiving section of the receiver 38 during normal use in the standby mode. . Therefore, a sub-microcomputer 54 with low current consumption is used, and a proper signal 56 is transmitted to the microcomputer 44 of the main body only when the reception signal 42 is correctly input.

[0026]

As described above, according to the present invention, the same signal is repeatedly transmitted to the remote controller, and the receiver is intermittently turned on and off, so that the power consumption during the off state of the receiver is reduced. Remote control can be performed reliably even in the intermittent reception state.
