Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 shows a schematic diagram for explaining the concept of the present invention.

The remote control 100 of the present invention receives the first wireless signal 211, preferably RF (Radio Frequency) signal from the wireless signal transmitter 210 to generate a power using it, the electronic product using the generated power Sending the remote control data for controlling the operation of the 200 to the remote control data receiver 220 of the electronic product 200 to operate the electronic product 200 according to the transmitted remote control data.

The technology for generating power using the RF signal and generating the signal using the generated power is a technology generally used through a traffic card, an RF ID tag, etc., and thus, a detailed description thereof will be omitted.

In addition, the intermediate processes generally used for transmitting and receiving wireless signals, such as modulation, demodulation, and detection, which occur in the process of transmitting and receiving a radio signal such as an RF signal, are not a feature part of the inventive concept of the present invention. Since it is a general technique for those skilled in the art, the description of the above process will be omitted.

In general, the distance between a device that generates power by using a wireless signal and a device that transmits a wireless signal that causes power generation and a device that receives a wireless signal and generates power is very close in the case of a traffic card. It is required that the distance between the two devices be adjusted according to the frequency band used.

For example, in the low frequency band of 150kHZ or less, the reading distance is 30cm or less, but in the 13.56MHz band, the reading distance is increased to 0.7m, and in the 300MHz to 1GHz band, more than 1m and 3m or more depending on the precision of the device, The use of higher frequency bands enables reading at greater distances.

In the present invention, the frequency band of the radio signal used to generate power of the remote controller 100 may be determined according to the expected interval between the remote controller 100 and the electronic product 200.

In the case of a remote control used only in the house, the interval may be shortened a little, and in the case of a remote control used in a factory, the interval should be longer than that used in the home.

In the present invention, the wireless signal transmitter 210 for transmitting a wireless signal for power generation in the remote control 100 may be provided in the electronic product 200, or may be configured separately from the electronic product. .

Currently, since electronic products used in homes do not have a function of transmitting RF signals in electronic products, it is necessary to replace electronic products in order to use the remote controller of the present invention.

However, when the wireless signal transmitter 210 is configured as a separate device, there is an advantage that there is no need to install a device for transmitting a wireless signal in each electronic product, and also by using one wireless signal transmitter 210. Advantageously, the wireless signal for power generation can be simultaneously transmitted to a plurality of remote controllers having the same configuration as the present invention.

2 is a block diagram showing the configuration of a remote controller according to an embodiment of the present invention.

The remote controller 100 of the present invention includes a switch 110, a transmitter 120, a power generator 130, a receiver 140, and a memory 150.

The receiver 140 receives a radio signal transmitted from the radio signal transmitter 210. The received radio signal is preferably an RF signal. However, since one of the features of the present invention is that power is generated using a radio signal, other types of radio signals can be used as long as it can be used as a radio signal used to generate power.

The power generator 130 generates power by using the wireless signal received by the receiver 140. As mentioned above, since a technology for generating power using a wireless signal is a technology generally used in a traffic card, an RF ID tag, and the like, a detailed description thereof will be omitted.

The memory unit 150 stores remote control data information for controlling the electronic product 200. In the memory unit 150 of FIG. 2, all remote control data of all functions for controlling the electronic product 200 are stored.

The switch unit 110 receives a command for driving the remote control from the outside for the user to control the electronic product 200. The switch unit 110 may be in the form of a key button, may be in the form of a touch screen, or may be in the form of a sensor that detects static electricity generated in the human body. It can be applied without. When a power source is required to drive the switch unit 110, the power source uses the power generated by the power generation unit 130.

In FIG. 2, only the numeric keys of the keys for receiving the input from the switch unit 110 are representatively illustrated. However, this is for convenience of description, and the switch unit 110 includes remote control data necessary for driving the electronic product 200. Of course, all the corresponding keys are provided.

The transmitter 120 extracts the remote controller data corresponding to the command input through the switch unit 110 from the memory unit 150 and uses the power generated by the power generator 130 to extract the extracted remote controller data. It transmits to the remote control data receiver 220 of (200).

The transmission unit 120 or the memory unit 150 is provided with a look-up table for indicating a position in which the command input through the switch unit 110 and the remote control data corresponding to the command is stored in the switch unit 110, The transmitter 120 extracts and transmits necessary remote controller data from the memory unit 150 using the lookup table.

In the present invention, the radio signal used for transmission in the transmitter 120 is not limited in kind. The power generation unit 130 may transmit by using the power generated, and may transmit remote control data, and the electronic product 200 may recognize the received remote control data received by the electronic product 200.

In general, the RF signal is most preferable because data can be transmitted even when a large power source is not generated in the power generator 130.

On the other hand, in the case of the electronic product 200 used in the home in general, since the infrared (Infra Red) signal is used as a signal for transmitting the remote control data, the transmitter 120 to prevent the replacement of the already sold household electronic products It is also possible to make the wireless signal generated by the infrared signal.

However, in order to generate an infrared signal, since a power source generally larger than an RF signal is required, the device constituting the power generator 130 is required to be more expensive, and the strength of the wireless signal transmitted from the wireless signal transmitter 210 is required. Is also required to grow.

In this case, the wireless signal transmitter 210 is installed near the seat where a person sits separately from the electronic product 200 so as to prevent a phenomenon that the strength of the wireless signal transmitted from the wireless signal transmitter 210 is attenuated according to the distance. Will work.

In FIG. 2, all the remote controller data necessary for the remote controller 100 is stored in one memory unit 150, and the remote controller data corresponding to the command input from the switch unit 110 in the transmitter 120 is stored in the memory unit 150. Although described as extracting and transmitting, a memory corresponding to each function may be separately provided in each function key provided on the remote controller.

FIG. 3 illustrates a configuration of an exemplary embodiment in which a switch unit 310, a transmitter 320, a power generator 330, a receiver 340, and a memory unit 350 are separately provided for each function key.

As mentioned above, in FIG. 2, the remote controller includes one transmitter 120, a power generator 130, a receiver 140, and a memory 150, according to the input from the switch 110. Although the remote controller data required by the memory unit 150 is extracted and transmitted, in the embodiment of FIG. 3, each of the function keys 300 includes a switch unit 310, a transmitter 320, and a power generator 330. The receiver 340 and the memory unit 350 are both provided, and the memory unit 350 includes only the remote controller data corresponding to the function key provided in the memory unit.

Since other functions are the same as those described with reference to FIG. 2, further description thereof will be omitted.

In FIGS. 2 and 3, the transmitters 120 and 320 operate according to the inputs of the switch units 110 and 310, and the power generators 130 and 330 always receive the receivers 140 and 340 regardless of the input to the switch unit. When a wireless signal is received through the configuration that generates the power using the received wireless signal is shown.

However, since the power generation unit does not always need to generate power, the power generation unit generates power only when a command is input through the switch unit, and transmits remote control data through the transmitter only when power is generated. .

4 illustrates a configuration of a system having a function of driving the power generation unit only when a command is input from the switch unit.

Here, the command input from the switch unit 410 may include not only a command for directly controlling the electronic product but also a command for driving the remote controller.

For example, in the case of a remote control used in a TV, when a user wants to move a channel, the user changes a channel of the TV by pressing a channel shift key or pressing the number of the corresponding channel. The power generation unit 430 may be driven to generate power from the moment when the button is pressed to the end of the input of the command, and the user presses a predetermined key for driving the remote control before pressing the channel shift key. After the key is pressed, the power generator 430 may be driven to generate power until the remote controller data signal is transmitted from the transmitter.

The configuration shown in FIG. 4 may be provided such that only one component is provided in one remote controller as shown in FIG. 2, and each component key included in the remote controller as shown in FIG. 3 may include all components. It may be.

5 is a flow diagram illustrating one embodiment of a method of the present invention.

For convenience of description, FIG. 5 will be described with reference to FIGS. 1 and 2 as follows.

First, the receiver 140 receives a first wireless signal, preferably an RF signal, from the wireless signal transmitter 210 when it is transmitted (501), and receives a wireless signal from the receiver 140, and then the power generator 130. In operation 502, power is generated using the received wireless signal.

When a user inputs a command for controlling the electronic device 200 through the switch unit 503 (503), the transmitter 120 transmits the remote controller data corresponding to the command input through the switch unit 110 to the memory unit ( Extracted from 150 and transmitted to the remote control data receiver 220 of the electronic product 200 in the form of a second wireless signal, preferably an RF signal or an infrared signal (504).

6 is a flowchart illustrating a method of another embodiment of the present invention.

6 is similar to that of FIG. 5, but in FIG. 5, when the receiver receives a radio signal, power is always generated from the power generator. In the method of FIG. 6, the user switches the key of the remote controller. The difference is that power is generated by pressing.

Here, the fact that the user presses a switch of the remote controller may include a command for driving the remote controller, including a command for instructing power generation from the remote controller as well as a command for directly controlling the electronic product. As we saw earlier.

The method of the present invention can also be embodied as computer readable code on a computer readable recording medium. The computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and may also be implemented in the form of a carrier wave (for example, transmission over the Internet). Include. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion.

As described above, the remote controller of the present invention does not require a battery, and there is an advantage that the user can use it permanently without having to perform an operation for specially charging the power of the remote controller.
