Description

Remote Controller System

The present invention relates to a remote controller system, and more particularly, to control various kinds of electronic products such as TV, audio, DVD player, VCR, etc. using a single remote controller, and having a Bluetooth communication module in place. The present invention relates to a remote controller system that can be controlled remotely without any particular concern.

In general, electronic products such as televisions and audio systems are controlled using a remote controller (hereinafter referred to as a "remote control"). The remote controller generates an infrared signal including a unique remote control code corresponding to a specific command, and the electronic product to be controlled receives an infrared signal, decodes the unique remote control code, and performs an operation according to the command. The configuration and operation of the remote controller will be described with reference to FIG. 1.

The remote controller may include a key input unit 11 through which a user inputs a command for controlling an operation of a corresponding electronic product, a memory 12 in which a unique remote control code is stored, and a user's key input to determine a user's key input. Reads the stored memory 12 to a unique remote control code, and controls the overall operation state of the remote controller 10, and an infrared output for outputting the signal restored by the microcontroller 10 as an infrared signal. It is comprised by the part 13.

When the user presses a key to which the function to be controlled of the corresponding electronic product is assigned in the key input unit 11, the microcontroller 10 reads the unique remote control code of the input key from the memory 12 and the manufacturer of the corresponding remote control. Decoded by applying to the remote control code system provided by the, and restored through the infrared output unit 13 to restore the unique remote control code. The output infrared signal is input to the infrared signal receiving window of the television or audio system to be controlled to perform the corresponding function.

The remote control code system for restoring the unique remote control code has a different system for each electronic product manufacturer and model. Commonly used remote control code systems include some information for implementing unique remote control codes, such as bit patterns, bit timings, remote control code bits, carrier frequency and headers. It consists of information about the presence or timing of a header or lead pulse, a stop or end pulse, a tail pulse, and a particular form and number of repetitions for performing the selected control.

An example of the unique remote control code is shown in FIG. The unique remote control code has a code system such as header pulse 1, remote control code 1, repetitive signal 1, header pulse 2, and the like, and an electronic product that controls a signal to perform a specific command by changing a pulse string of the remote control code 1 Send it out. The schemes differ from one manufacturer to another.

The conventional remote control as described above has a different remote control code system for each manufacturer and model, so there is no interoperability. Because of this characteristic, if a conventional remote control is lost or malfunctions, there is a problem in that a remote control having a unique remote control code of the corresponding electronic product must be purchased separately.

In order to solve this problem, the universal remote control is sold, but since the universal remote control is specialized in one type of electronic product such as a television or an audio system, there is a problem that it is difficult to apply to all kinds of electronic products.

In addition, due to the frequent upgrades and short life cycles of electronic products, new products with new functions have emerged. Therefore, every time a new product is purchased, the user must use a remote control having a unique remote control code for the electronic product. There is a problem.

In addition, the conventional remote control transmits a signal using infrared rays, and since infrared rays have directivity, it is inconvenient to control a television or an audio system placed in a living room in a room or cause a malfunction.

This problem is particularly noticeable when simultaneously controlling a large number of electronic products such as a home theater system. In other words, if a TV, DVD player, VCR, amplifier, luminaire, or skipper constituting a home theater system is purchased from one system manufacturer, an integrated remote controller is provided, so there is no problem in control. When configuring a system by purchasing electronic products, there is a problem that all remote controllers suitable for the electronic products should be provided.

The present invention is to solve the above problems, an object of the present invention is to control a variety of electronic products such as TV, audio, DVD player, VCR using a single remote controller, Bluetooth communication module is provided It is to provide a remote controller system that can be controlled remotely without regard to the place.

Another object of the present invention is to provide a remote control controller system that can be mounted on a terminal such as a desktop computer, a notebook computer, a PDA, a mobile phone, a smart phone, and the like, which can control various electronic products at a remote location.

Another object of the present invention is to provide a remote controller system capable of changing a unique remote control code of a product to be released as well as existing products by easily changing a unique remote control code and a corresponding binary code of a plurality of electronic products.

It is still another object of the present invention to provide a remote controller having a graphic user interface capable of easily adding or deleting unique codes of various remote controllers, and thus changing unique remote control codes of existing products as well as existing products.

In order to achieve the above object, the remote controller system of the present invention detects a signal input generated when a signal for performing a specific command is generated among function execution commands set in each electronic product, and generates a unique remote control code corresponding to the corresponding signal input. Reads the binary code and encodes the binary code and transmits the binary code through the communication module, and receives the binary code from the remote control unit 20 through the communication module and decodes the unique remote control code into an infrared signal. It characterized in that it comprises a real-time remote controller 30 for outputting.

Hereinafter, the remote controller system of the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram of a remote controller system according to the present invention, and is divided into two parts, a remote controller 20 and a remote controller 30. The remote control unit 20 may be a remote place, for example, a room or a kitchen, and the electronic product to be controlled is a TV, an audio system, a speaker, a VSI, a DVD in a living room blocked by a shield such as a wall. It may be possible to control using a remote control, such as. For convenience of description, in the following description, the communication module is described as using a Bluetooth module, but is not limited to the Bluetooth module.

The remote control unit 20 detects a signal input generated when a signal for executing a specific command is generated among the function execution commands set for each electronic product, and encodes a binary code by reading a unique remote control code corresponding to the corresponding signal input. The binary code is transmitted through the Bluetooth module, and the remote controller 30 receives the binary code from the remote control unit 20, decodes the binary code into a unique remote control code, and converts the binary code into an infrared signal.

The remote controller 20 reads an input unit 21 for inputting a function command for a specific electronic product and a unique remote control code corresponding to the function command for the specific electronic product input through the input unit 21. A control unit 22 for encoding the binary code using the binary code system and outputting the binary code, a Bluetooth module 23 for transmitting the encoded binary code according to the command of the control unit 22, and a user-specified electronic And a display unit 24 for outputting a menu screen to select a product.

The input unit 21 may be, for example, a means such as a data input pen including a direction selection arrow, a keypad, a mouse, or a keyboard. The signal input through the input unit 21 is a command corresponding to a function for a specific electronic product.

When a specific function command is input, the controller 22 generates a "remote control code making event". The "remote control code making event" is performed by the controller 22 to convert the unique remote control code into a binary code. The execution program is stored in the program memory 22b.

The control unit 22 reads the unique remote control code for the electronic product corresponding to the command. This unique remote control code is read by reading the corresponding remote control code stored in the data memory 22a.

After the unique remote control code is read as described above, the unique remote control code is encoded into a binary code using a "binary remote control code system". The encoded binary code is transmitted by the "Bluetooth Sending Event". The "binary remote control code scheme" is described later. Such an event is shown in FIG. 3. 3 is a conceptual diagram of the performance of the remote control unit 20.

Meanwhile, the controller 22 of the present invention may decode the binary code encoded by the "remote control simulation event" into a unique remote control code using a "binary remote control code system" and then simulate it in a graphic state.

The Bluetooth module 23 is a wireless transmission / reception module that satisfies the Bluetooth communication protocol and is widely used in a local area network. In the present invention, it can be configured using a Bluetooth module such as LMX9814 of National Semiconductor, which has been widely commercialized recently. It is also apparent that it is also possible to use a radio transmitting / receiving device having another frequency band conventionally used as long as it does not violate the law instead of the Bluetooth module.

In addition, the display unit 24 displays a menu screen for allowing a user to input a function activation command for a specific electronic product under the control of the controller 22. In other words, the display unit 24 allows the user to easily search for the electronic product he wants to control by using the graphical user interface and input a specific command. 5A to 5C show menu screens using a PDA equipped with a Bluetooth module as the remote control unit 20.

5A is a screen for allowing a user to select a specific electronic product. As shown, a selection menu for an electronic product such as a television, audio, speaker, DVD, VCR, or the like is output. The user selects an electronic product to be controlled on the menu screen. The menu can be selected by using an input pen or a key installed in the main body. On the other hand, when using a computer as the remote control unit 20, the input may be a mouse or a keyboard.

When the user selects the television, a list of the make and model name of the television is output as shown in FIG. 5B. The user here selects the model name he owns or wants to control. When the user selects the model name of the television, the remote control is displayed on the graphic screen as shown in Fig. 5C. The user completes the input to perform the corresponding command by selecting a specific function button on the remote control. Function command selection for other electronic products in addition to the television can be performed in the same manner as described above.

The control unit 22 of the present invention stores all the data for the unique remote control code for the specific electronic product selected by the user. That is, when the user selects a specific function on the screen as shown in Fig. 5C, the controller 22 reads the unique remote control code data for the selected function command from the data memory 22a. After reading the unique remote control code data, encoding is performed by the "binary code system". This process is essentially a "remote code making event" shown in FIG.

A process of converting a code using the "binary remote control code system" will be described with reference to FIG. 4. The binary remote control code scheme is to improve the different remote control code schemes previously provided by manufacturers, to integrate and unify the unique remote control codes, and to implement all different unique remote control codes.

The binary remote control code system implements the information of the unique remote control code into 1. remote control code frame, 2. remote control code timing, and 3. remote control code data, and all the information is represented by binary values of "0" and "1". The three pieces of configuration information combine and unify the unique remote control code information to generate an encoded binary code. The encoded binary codes generated as described above are correctly decoded and output from the remote controller 30 to control specific electronic products.

Referring back to FIG. 4, the unique remote control code is converted into three pieces of configuration information: 1. remote control code frame, 2. remote control code timing, and 3. remote control code data using a binary remote control code system. It is possible. In particular, the conversion (decoding) in the opposite direction is performed at the remote controller 30. Since the decoded signal is identical to the original unique remote control code, the electronic product recognizes the command and executes the command.

The remote control code frame represents the overall structure and pattern (type) of the unique remote control code signal, which includes 1) remote control code signal structure frame, 2) number of bits of custom (or address) code, 3) number of bits of data code, 4 Repeat signal structure frame, 5) Configuration type of custom and data code, 6) Input key repeat type, 7) Toggle bit type, 8) Toggle bit positioning, 9) Bit 0 pattern type, Bit 1 pattern type, 10 It consists of the type of tail code.

The remote control code frame configured as described above may be defined in detail as follows. In the following, "1" indicates activation, "0" indicates deactivation, and "X" indicates Don't Care regardless of activation.

1) The remote control code signal structure frame includes information for determining whether the signals constituting the standardized remote control signal structure frame are activated. Referring back to the drawings, the unique remote control codes are binary codes of (8 bits + 8 bits) and can be displayed in all 16 bits.

The first 8 bits are 'Header pulse 1 + remote control code 1 + repeat signal 1 + header pulse 2 + tail code 1 + remote control code 2 + repeat signal 2 + header pulse 3', and the last 8 bits are 'tail code 2 + remote control Conduit 3 + Repeat signal 3 + Frame repeat signal + Stop pulse + reservation + reservation + reservation ". If the binary code is '11111000' or '00011XXX', 'Header pulse 1-Remote control code 1-Repeat signal 1' -Header pulse 2-Tail code 1-Frame repeat signal-Stop pulse 'is activated.

2) The number of bits of custom code is 0 ~ 128 bits and it is represented as 'reservation + 64 + 32 + 16 + 8 + 4 + 2 + 1'. For example, 'X1000001' is 64 + 1 = 65 bits.

3) The number of bits of the data code has 0 to 128 bits, and it is structured as 'Reservation + 64 + 32 + 16 + 8 + 4 + 2 + 1'. For example, 'X0011100' is 16 + 8 + 4 = 28 bits.

4) The repeated signal structure frame includes information for determining whether the signals constituting the repeated frame are activated.

This means' Header pulse 1 + remote control code 1 + repeat signal 1 + header pulse 2 + tail code 1 + remote control code 2 + repeat signal 2 + header pulse 3 ',' tail code 2 + remote control cone 3 + repeat signal 3 + frame repeat Signal + stop pulse + reservation + reservation + reservation. For example, '00011000' and '00010XXX' are activated with 'header pulse 2-tail code 1-frame repeat signal'.

5) The custom and data code configuration type indicates whether or not the information constituting the custom and data codes of the remote control code 1, the remote control code 2 and the remote control code 3 of the remote control code signal structure frame of 1) is activated. In the following, the slash '/' denotes a value in which the corresponding value is inverted.

It has a structure represented as 'custom + / custom + data + / data + custom + / custom + data + / data', for example '10100101', means 'custom + data + / custom + / data' do.

6) The repetition type of the input key is for indicating information when the continuous repetitive signal is outputted and when the repetitive signal is not outputted according to the type of the input key. This is indicated as 'Repeat all keys + repeat channel key + repeat volume key + repeat direction keys + reserve + reserve + reserve'.

Here, 'Repeat All Keys' repeats all the key inputs. 'Channel key repeat' outputs repeatedly when channel key is input. 'Repeat volume key' repeats output when volume key is input. 'Repeat direction key' repeatedly outputs when the direction key is input. For example, if '0110XXXX', only the channel key and the volume key are repeatedly output.

7) The toggle bit type is for toggling a unique remote control code in various forms at bits at a certain position of the remote control code. This is expressed in the form of 'General Toggle + 2 Bit Toggle + Channel Toggle + Rc Toggle + Reservation + Reservation + Reservation + Reservation.

'Normal Toggle' toggles the bit signal at the active position in the eighth toggle bit position to bit 0 and bit 1. '2-bit toggle' toggles the sequence of 2-bit values activated in the 8th toggle bit position from '00'-'01'-'10'-'11'. 'Channel Toggle' sequentially increases or decreases the channel key data value up to the numerical keys 0-9. 'RC toggle' is the RC toggle timing of 'remote code timing' described below at the position set first in the eighth toggle bit position, and toggles between bit 0 and bit 1. For example, '0001XXX' would be a toggle of eggs.

8) Toggle bit position setting is to set 4 toggle bit positions at the same position of remote control code 1, remote control code 2 and remote control code 3 of the remote control code signal structure frame of 1). The first toggle bit position is 'Reservation + 64 + 32 + 16 + 8 + 4 + 2 + 1', the second toggle bit position is 'Reservation + 64 + 32 + 16 + 8 + 4 + 2 + 1', The third toggle bit position is 'Reservation + 64 + 32 + 16 + 8 + 4 + 2 + 1', and the fourth toggle bit position is 'Reservation + 64 + 32 + 16 + 8 + 4 + 2 + 1' In the form of: For example, if the 7th toggle bit type is a 2-bit toggle of '0100XXXX', the first and second bits of the remote control code 1 of 1) are 2-bit toggled.

9) The pattern types of bits 0 and 1 are defined as whether the 'high' and 'low' outputs of the four pulses are enabled. The following English notation is indicated by the following abbreviations. B0 is bit 0, B1 is bit 1, P is pulse, H is high output of pulse, L is low output of pulse.

Bit0 pattern is represented as' B0_P1_H + B0_P1_L + B0_P2_H + B0_P2_L + BO_P3_H + B0_P3_L + B0_P4_H + B0_P4_L ', and bit1 pattern is' B1_P1_H + B1_P1_L + B1_H1 + B_P1_P1_2 do. For example, bit 0 and bit 1 of a commonly used RC5 remote control code are expressed as follows.

RC5 bit 0 '11000000' = B0_P1_H + B0_P1_L

RC5 bit1 '01100000' = B0_P1_L + B0_P2_H

10) The type of tail code is for setting the code types of tail code 1 and tail code 2 of the remote control code signal structure frame of 1). It is displayed as 'tail 0 type + tail 1 type + tail 2 type + tail 3 type + tail 4 type + reservation + reservation + reservation'.

Tail 0 type outputs pulse of bit 0, Tail 1 type outputs pulses of bit 0 and bit 0, Tail 2 type outputs pulses of bit 1 and bit 0, Tail 3 type outputs bit 1 and bit A pulse of 1 is output and the tail 4 type outputs a tail pulse of the remote control code timing. For example, '01000XXX' is a tail1 type and outputs a 'bit 0 pulse + bit 0 pulse' type.

The remote control code timing is for displaying all pulse timings of the unique remote control codes and includes information necessary for timing. Remote control code timing includes high and low pulse timing of carrier pulse, pulse high and low timing of bit 0, pulse high and low timing of bit 0, pulse high and low timing of bit 0, bit 4 of bit 0, and Pulse high and low timing, bit 1 pulse high and low timing, bit 1 pulse high and low timing, bit 1 pulse high and low timing, bit 1 pulse high and low timing , High and low timing of header pulse 1, high and low timing of header pulse 2, high and low timing of header pulse 3, timing of repetitive signal 1, timing of repetitive signal 2, timing of repetitive signal 3, high of stop pulse And low timing, high and low timing of the tail pulses.

In addition, the bit 1 high timing 560us is represented as '00000010,00110000', which is '512 + 32 + 16 = 560'. In addition, the bit 1 low timing 1690us is represented as '00000110,10011010', which is '1024 + 512 + 128 + 16 + 8 + 2 = 560'.

For example, 40500us, the repetitive signal1 full timing of NPD's uPD6121G, can be expressed as 40500 = 5063 X 8us, and 5063 can be expressed as '00010011,11000111', and '4096 + 512 + 256 + 128 + 64 + 4 + 2'. + 1 = 5063 '.

5) The high and low timings of the stop pulse and the low pulse are in the range of 0 to 65535us in 1us units, and the high and low timings of the stop pulse are '32768 + 16384 + 8192 + 4096 + 2048 + 1024 + 512, respectively. + 256 + 128 + 64 + 32 + 16 + 8 + 4 + 2 + 1 '.

For example, 560us, the stop pulse high timing of NEC's uPD612G, is represented as '00000010,00110000', which is '512 + 32 + 16 = 560'. In addition, the stop pulse low timing 565us is represented as '00000010,00110101', which is '512 + 32 + 16 + 4 + 1 = 565'.

The remote control code data also includes information on the unique remote control code and input key information of the remote controller according to the number of bits of the custom code and the number of bits of the data code defined in the remote control code frame. In short, the remote control code data consists of information, custom codes, and data codes of input keys of the remote controller.

1) Input key is to set input key used in normal remote controller, and it is in the range of 0 ~ 65535, and the key value is' 32768 + 16384 + 8192 + 4096 + 2048 + 1024 + 512 + 256 + 128 + 64 + 32 + 16 + 8 + 4 + 2 + 1 '.

For example, if the remote control has 44 keys, the input key value is displayed using 1 to 44. The power key is 1 and the channel-key is 20. The power key is displayed as '00000000,00000001', which is 1 = 1. The channel-key is also labeled '00000000,00010100', which is 16 + 4 = 20.

2) The custom code is defined as 0 to 128 bits in size according to the number of bits of the custom code defined in the remote control code frame and becomes a variable code. For example, if the number of custom bits of the remote controller is 8 bits and the value is 10, it is indicated by the custom value '00001010', which is 8 + 2 = 10.

3) The data code is defined in size from 0 to 128 according to the number of bits of the data code defined in the remote control code frame, and becomes a variable code. For example, if the number of data bits of the remote controller is 8 bits and the value is 9, the data value is displayed as '00001001', and 8 + 1 = 9.

As described above, in converting a unique remote control code of each electronic product (manufacturer-specific or model-specific) into a binary code, since the unique remote control codes are different from each other, there is little possibility of generating the same binary code. The binary code is decoded into the original unique remote control code in the remote controller 30 and then included in the infrared signal and transmitted.

The advantage of converting and transmitting the unique remote control code into a binary code is that storing the information on each unique remote control code in the remote control unit 20 can control all electronic products in which the unique remote control code information is stored, and update of information It is easy to expand the scope of control by adding information about new products. The addition of a unique remote control code of the new controlled electronic product can be achieved by further providing an interface for data communication in the remote control unit 20.

If the remote control unit 20 is a computer, if it is connected to the Internet, the data is updated through an internet communication network or directly from a floppy disk. In the case of a PDA, a mobile phone, or a smart phone, the remote control unit 20 can transmit the same method as a general multimedia data transmission through a built-in CDMA communication module.

The transmitted data is added to an area in which a list of electronic products and a unique remote control code are stored, and the controller 22 outputs the list after the data is updated or periodically by newly sorting and outputting the newly added electronic products. To facilitate searching. The above programs executed by the control unit 22 are stored in the program memory 32b.

The above-described binary remote control code system may be configured to convert in a manner different from that shown in FIG. 4, and all such modifications and changes are within the scope of the present invention.

The unique remote control code encoded with the binary code transmitted from the remote control unit 20 is received by the remote controller 30. The remote controller 30 receives a Bluetooth module 33 for receiving a radio signal including a binary code, and receives a binary code input from the Bluetooth module 33 and decodes it into a unique remote control code, and decodes the original. A remote control unit 32 for outputting a remote control code signal, an infrared output unit 34 for modulating and outputting a unique remote control code output from the remote control unit 32 into an infrared signal, and a control output from the control unit 32 And a display unit 35 for displaying the operation state of the remote controller 30 according to the signal.

The Bluetooth module 33 corresponds to the Bluetooth module 23 of the remote control unit 20, receives the transmitted radio frequency, and extracts only the binary code by removing the high frequency component. The extracted binary code is input to the remote controller 32.

The remote control unit 32 decodes the input binary code into an original unique remote control code using a real-time binary remote control code system. In addition, after decoding is completed, to output the command to the electronic product to the infrared output unit 34. The infrared output unit 34 is configured using an infrared light-emitting diode. In addition, a control signal is output to the status display unit 35 so as to display an operating state of the remote controller 30. The state display unit 35 may be configured using a light emitting diode and displays a current state by using a diode having various colors.

In order to perform the above functions, the remote controller 32 is a general purpose such as HMS810 series of Hynix, S308 series of Samsung Electronics, 17K series of NEC, 8051 series of Intel, PIC series of microcontroller, Atmel AVR series, or the like. A dedicated microcontroller can be used.

The present invention further includes a remote controller input unit 31 so that the remote controller 30 itself can be used. The remote controller input unit 31 includes a plurality of function command input keys (or buttons) and the like. The function execution command input through the remote controller input unit 31 is input to the remote controller control unit 32. The remote controller 32 requests the remote controller 20 to generate an input function command execution code.

When the remote controller 20 receives data for a specific command from the remote controller 32, the corresponding remote controller code is read, the read unique remote controller code is encoded using a binary remote controller code system, and the binary code is converted into a Bluetooth module. Transfer to the remote controller 30 through the (23).

The transmitted signal is received by the Bluetooth module 33 of the remote controller 30 and then decoded into a unique remote control code by the binary remote control code system and then output through the infrared output unit 34. Inputting a specific function execution command through the remote control input unit 31 is essentially the same as inputting through the input unit 21 of the remote control unit 20. The difference is that the function command is performed wirelessly.

Since the remote control input unit 31 is hardware having a plurality of keys, it is difficult to select various electronic products such as the input unit 21. Therefore, the remote control input unit 31 should be fixed for one electronic product, and this setting can be made using the remote control unit 20.

That is, when the remote controller 20 sets the remote controller input unit 31 of the remote controller 30 to the television of the specific model of the specific manufacturer in the electronic product, the remote controller 20 inputs from the remote controller input unit 31 unless a new change is made. The function command to be encoded is encoded based on the unique remote control code assigned to the television.

Alternatively, the remote control unit 20 transmits the unique remote control code of the electronic product (TV in the above description) set in the remote control input unit 31 from the remote control unit 20 to the remote controller 30, and the remote control unit of the remote controller 30 ( In 32), the transmitted unique remote control code data is stored in the built-in data memory 32a, and when a specific function command is input from the remote control input unit 31, the unique remote control code assigned to the corresponding function command is read, and the infrared output unit The transmission is through 34. Therefore, it is possible to easily control the electronic products mainly used, such as a television.

The remote controller input unit 31 may also set one or more electronic products. In other words, a plurality of dip switches and the like are connected to the remote controller 32, and a television, an audio system, a DVD, a VCR, a speaker, and the like are selectively set according to the connection state of the dip switches. The manufacturer-specific model setting for each electronic product is made in the remote controller 20 as in the above-described setting of the television, and each of the selected manufacturer-specific model-specific remote control codes are transmitted to the remote controller 30 to control the remote controller ( 32 is stored in the data memory 32a.

The user selects an electronic product he wants to control using a dip switch (or a selection button) and then presses a button of the remote controller input unit 31 to input a specific function command. After checking the current setting state, the remote control unit 32 reads the unique remote control code corresponding to the function command to be input and transmits it through the infrared output unit 34.

The present invention having the above-described configuration will be described with reference to FIGS. 6A-6B which are flowcharts showing an operating state of the remote controller 30.

When the power is supplied, the remote controller 32 performs initialization. Initialization determines whether the data memory 32a is damaged as shown in FIG. 6B, and initializes the memory when the memory is damaged. After initialization, retrieve the initialization of the system flag. Once the system flag has been initialized, the stop mode entry and external interrupt of FIG. 6A are checked. However, if the system flag is not initialized, initialize the Bluetooth module.

At this time, if an error occurs in the Bluetooth module, it displays the fault condition to the user. The indication of the fault condition uses the status display section 35.

If no error is detected in the Bluetooth module, the remote controller (key) input unit is scanned (only when the remote controller input unit 31 is installed). At this time, if an error occurs, the status display unit 35 notifies. If no error is detected, initialize the system flag.

After system flag initialization, check stop mode entry and external interrupt. If the external interrupt is a Bluetooth module input, it is determined whether the input signal is a binary code. If it is a binary code, the binary code is decoded into a unique remote control code using a binary remote control code system. The decoded unique remote control code is output to the infrared output unit 34. The infrared output unit 34 modulates and outputs the infrared signal. At the same time, an operation state is displayed through the status display unit 35.

In the present invention, when the remote controller input unit 31 is connected at the same time, a signal can be input from the remote controller input unit 31 as an external interrupt. In this case, the encoded binary code assigned to the key (or button) of the remote control input unit 31 is read. This reading process can use two methods as described above.

The unique remote control code is restored using the read encoded binary code, and the unique remote control code is output to the infrared output unit 34. The infrared output unit 34 modulates and outputs the infrared signal. At the same time, an operation state is displayed through the status display unit 35.

On the other hand, if the signal input by the external interrupt is new setting data of the remote control input unit, the key assignment data of the remote control input unit 31 is updated. The data to be updated is stored in the data memory 32a.

Figure 7 shows the usage of the remote controller system of the present invention.

As shown, the remote control unit 20 and the remote controller 30 is located within a distance (10 ~ 100m) Bluetooth communication is possible. Since the Bluetooth module can pass through walls or doors, there is no problem in communication even if the shield 40 is present in the middle.

The function command signal input through the remote control unit 20 is transmitted as a radio frequency signal. The transmitted signal is output as an infrared signal after being received by the remote controller 30. A plurality of electronic products 41-46 are located within a distance (about 10 to 20 m) from which the infrared signal can be communicated from the remote controller 30. Each electronic product is oriented to receive an infrared signal. In particular, the remote controller 30 is fixed in one place, thereby reducing the risk of loss or damage.

When the user selects a specific electronic product using the remote control unit 20 in a place where the remote control unit 20 is located, for example, a room or a kitchen, and inputs a specific function command, the electronic product is operated.

The remote control unit 20 may be configured as a separate device or by using a communication terminal such as a desktop computer, a notebook computer, a PDA, a mobile phone, and the like. In this case, since the input unit 21, the control unit 22, and the display unit 24 of the remote control unit 20 can share those already present in the corresponding devices, the addition of the Bluetooth module 23 It can be easily configured only by adding the control program and the control data. Therefore, when included in PDA, mobile phone, etc., since the portability increases, it can be used very usefully. It is also apparent that the apparatus of the present invention can be applied to home automation.

In the above description of the present invention has been described that the remote control unit 20 and the remote controller 30 is separated and transmitting data by the communication using the Bluetooth module. However, when such remote control is not necessary, it can be combined with a single remote controller and used as in the prior art.

According to the present invention, a plurality of electronic products, such as a home theater, can be controlled using a single remote controller, and in particular, equipped with a Bluetooth communication module to control a variety of electronic products from a remote location without regard to the place It can work. In addition, it can be mounted on a terminal such as a computer, a notebook computer, a PDA, a mobile phone, a smartphone, and the like used in the related art so that various electronic products can be controlled from a remote place. In addition, by easily changing the unique remote control code and the corresponding binary code of a plurality of electronic products, it is possible to change the unique remote control code of the existing product, as well as the product to be released. In addition, since it is possible to easily add or delete unique codes of various remote controllers, there is an effect of providing a remote controller having a graphic user interface capable of changing a unique remote control code of a product to be released as well as existing products.
