Description

Control code selection method and device of integrated remote control transmitter

The present invention relates to a method and an apparatus for automatically selecting a remote control code of a remote control transmitter, and more particularly, to a control code of a home appliance when operating an integrated remote control transmitter to control a plurality of home appliances using a single remote control transmitter. Select to automatically match the control code of the home appliance and the control code of the remote control transmitter to be controlled by the user.

The remote controller (remote control device) for remote control of TV receivers, VCRs, audio equipment, etc. employs a unique method mutually promised according to the transmission, frequency, and encoding methods between the transmitter and the receiver. This prevents errors caused by each other of home appliances, and therefore, it is common to control a remote controller (transmitter) for a specific home appliance.

That is, the conventional remote control transmitter can control only one home appliance, so in order to control a plurality of home appliances, the remote controller transmitter needs to be the same as the number of home appliances, so there is a risk of losing the remote controller transmitter. When controlling the home appliances through the unit (1) there was an inconvenience to control the home appliances only if the representative control code of the home appliances have the same remote control.

However, as the prevalence of home appliances has increased, homeowners have many remote control transmitters, which causes confusion in their use and management. Therefore, two or more different types of remote control codes may be assigned to one remote control transmitter. The built-in allows the user to select a code corresponding to the home appliance to be used as needed.

Such a remote control transmitter is called an integrated remote control transmitter, and the integrated remote control transmitter has a control code corresponding to a plurality of home appliances, and a task for finding and matching a control code corresponding to a single home appliance among the various control codes is existing. In the integrated remote control, the manual operation by manual is complicated, so it is inconvenient and difficult to match the code between the transceivers.

1 illustrates a circuit configuration of a conventional integrated remote control transmitter as described above. Referring to this, the conventional remote control transmitter includes a key matrix unit 1 for selecting a desired signal from a user and a key matrix unit 1. A timer unit 2 for outputting time information on the high time and the low time of the selected output pulse, and a CPU which performs various operations of the remote control transmitter by a program stored in the ROM 3 in which the operation program of the remote control transmitter is stored; 4), RAM 5 for temporarily storing control signals output when the CPU 4 is driven, and RAM for temporarily adjusting control signals output when the CPU 4 is driven by a program stored in the ROM 3; (5) and a control signal output unit 6 for outputting a control code of a remote control transmitter when the CPU 4 is driven by a program stored in the ROM 3, wherein 7 is an oscillator and C-tal is Crystal, D1 is a light emitting diode All.

As shown in FIG. 1, the conventional remote controller configured as described above has different unique numbers assigned to the home appliances of all companies, and thus, when the user presses the key matrix unit 1 of the remote control transmitter, the RAM 5 is a key matrix. By temporarily storing and decoding the key signal outputted from the unit 1, the control code of the home appliance desired by the user is made to match the control code output from the remote control transmitter.

That is, according to the operation program of the remote control transmitter stored in the ROM 3, the CPU 4 detects whether the key signal selected by the key matrix unit 1 is output without error.

If the key signal is output without error as a result of the detection, after a predetermined time has elapsed according to the time information set in the timer unit 2, check whether the desired home appliance is selected by pressing a unique number assigned to the home appliance of each company.

As a result of the check, if the unique number of the home appliance to be controlled by the user is pressed without error, the control unit outputs a control signal from the control signal output unit 6 by controlling the CPU 4 to control the home appliance desired by the user.

However, such a conventional integrated remote control transmitter is also inconvenient to match the control code.

That is, the conventional remote control can control only one home appliance, so in order to control a plurality of home appliances, the remote controller transmitter needs to be the same as the number of home appliances, so there is a risk of losing the remote controller transmitter, and the key matrix part of the remote controller transmitter ( When controlling the home appliances through 1) there was an uncomfortable problem of pressing the key matrix unit 1 several times to match the reception control code of the home appliance.

In order to solve the conventional problem, the present invention uses one integrated remote control transmitter to control one of a plurality of home appliances desired by a user. One remote control transmitter is automatically searched and the remote control code is automatically selected as soon as the user ends the search setting when the control code of the remote control transmitter and the reception control code of the home appliance match. The purpose is to allow the user to easily select and control the home appliances specified by each unique number.

In addition, the present invention is to control the receiver by pressing the search setting key provided in the remote control transmitter to control one of a plurality of home appliances desired by the user using a single integrated remote control transmitter to solve the above-mentioned problems Automatic search for codes, and the user can easily select and control the home appliances to which each unique number is assigned by using the remote controller to control the response of the home appliance that appears when the control code of the remote controller and the reception control code of the home appliance are matched. The purpose is to make it possible.

Hereinafter, the configuration and operation of the present invention will be described with reference to the accompanying drawings.

First, Figure 2 shows the circuit configuration of the first embodiment of the remote control transmitter of the present invention for achieving the above object.

Referring to FIG. 2, the remote control transmitter of the present invention includes time information about a high matrix time and a low time of a key matrix unit 11 for selecting a signal desired by a user and a pulse selected by the key matrix unit 11. A timer (12) for outputting a; a ROM (13) in which an operation program of a remote control transmitter is stored; a ROM (14) in which reception control code information of a home appliance for which a unique number is assigned is stored; The search setting key unit 18 for searching for the control code of the same receiver as the control code outputted during the general operation of the remote control transmitter by the program stored in (13), and the control code of the same receiver as the control code of the remote control transmitter. It consists of a display unit 19 for emitting the light emitting diode (D11) by a program stored in the ROM (13) so that 20 can be confirmed, 20 is the oscillator, C-tall is a crystal, D12 is a light emitting diode .

And, Figure 3 shows a control code selection method of the integrated remote control transmitter of the present invention, referring to the control code selection method of the present invention is a single remote control transmitter to match the corresponding control code with a plurality of remote control receivers (products) A first step of determining whether the search setting key for searching and the representative key for searching for the representative control code of the corresponding receiver are turned on at the same time; and when the search setting key and the representative key are turned on simultaneously, A second process of periodically outputting the representative control code; and if the key is turned off during the execution of the second process, it is determined that the remote control control code output at that time is selected and all remote control corresponding to the representative control code are selected. Integrated remote control transmitter consisting of a third step of storing the code in the remote control mode matched with the receiver Control code selection method.

The control code selection operation by the integrated remote controller transmitter of the present invention configured as described above will be described with reference to FIGS. 2 and 3.

Since the home appliance of every company is assigned a unique number, when the user presses the key matrix unit 11 to control the home appliance of the desired company, the key signal selected by the key matrix unit 11 is output to the RAM 16. Temporarily stored in to decode.

In other words, all home appliances have a unique number (customer code: 01,02,03,04, etc. for each maker) and a control code (control commands of the remote control using a code system such as NEC, MITSUBISH). In order to integrate and control a plurality of home appliances, a control key (power on / off, channel up / down, playback, recording, etc.) for outputting a control command of a corresponding device equipped with a remote controller, and a unique number and control code of the corresponding device. If you press the corresponding key after selecting, the unique number and control code for the corresponding device will be output. First, the control code of the corresponding device needs to be selected.

Therefore, the first embodiment of the present invention will be described below.

First, a search setting key is provided to start and end the above control code selection operation, and an arbitrary key that stores a representative control key of each home appliance is provided to output control codes for each home appliance manufacturer. The representative control code may be set to the power key of the TV or the volume key of the audio device. For example, the first control code is matched with the representative TV control code. When key and No.1 key are pressed, the company's TV power on command, the company B's TV power on command, and the company C's TV power will output the representative control codes for each manufacturer in the order, etc. As described above, it is possible to match the representative control code for the VCR and the CD player for the second time. As described in more detail with reference to FIG. 3, first, the search setting key is pressed. If the search setting key is pressed after determining whether the key has been pressed, if any key (device selection key such as TV or VCR) is pressed after a predetermined time delay, if it is not pressed, it is determined as an error and the search operation is terminated. If it is determined that the key is 1, the control code for the TV is selected. Therefore, the representative control code (for example, power-on) for the TV of the company A is output.

At this time, when the controlled TV responds with the power-on operation, the viewer judges that the product is the same and presses the search setting key to store the unique number and control code information of the TV of the company A in the RAM and perform the search operation. If the TV, which is the controlled device, does not respond, the viewer does not press the search setting key and then outputs the stored manufacturer-specific control codes such as B, C, and D.

Therefore, as described above, if the arbitrary key is the second key, it is determined as a control code selection process for the VCR, and the control code for the determination is representatively outputted for each company, so that the viewer visually discriminates the corresponding operation and makes the corresponding selection.

That is, when the search setting key unit 18 and another arbitrary key are pressed simultaneously to select the control code of the same receiver as the control code output when the remote control transmitter is operated, the representative control code of the A company is outputted first. The CPU 15 controls the display unit 19 so that the light emitting diode D11 is driven by a program stored in the ROM 13, so that the user can visually (audibly configure the display unit with a buzzer) an output to the remote control transmitter. You can check the control code of the same receiver.

At this time, when the state of the receiver changes, that is, the power is turned on in the case of a TV and the volume is increased in the case of an audio device, and the receiver changes in response to a change in the state of the receiver, the user sets a key between the search setting key unit 18 and any key. When released, the control code of the same receiver as the control code of the remote controller transmitter most recently output is temporarily stored in the RAM 16.

On the other hand, if the control code output from the remote control transmitter and the control code of the receiver is not the same, if the user continuously pressing the search setting key unit 18 and any key, according to the reception information of the receiver stored in the ROM (14) The representative control code of B company, not A company, is output.

Therefore, when the user keeps pressing the search setting key part 18, the display unit 19 can visually confirm that the representative control code of each company is periodically outputted. Therefore, the user can search the search setting key part according to the state of the receiver. By controlling the (18) and arbitrary, the user can control the desired product.

In the first embodiment of the present invention described above, the user directly monitors the response of the device to determine whether the control codes match, and turns off the search setting key and any key to correspond to the code group represented by the representative control code at that time. Some inconveniences are caused by preempting the control code of the equipment.

Therefore, in the present invention, the second embodiment is to automatically determine the visually discriminated operation and to select and store the control noses. For example, the light sensor detects the change in brightness of the light according to the screen on / off according to the power on / off and performs the visual judgment of the viewer automatically.In the case of audio, the optical sensor can be judged as the volume. It will be equipped to detect the reaction.

In FIG. 4, the same components as in FIG. 2 are denoted by the same reference numerals, and the reaction detecting unit 21 may be recognized by the CPU 15 according to an operation response of a device to be controlled. It can be implemented by the circuit structure which outputs an electrical signal.

For example, in the case of a TV, if the representative control code is searched with the power on / off key code, the TV responding to the output of the representative control code of the integrated remote controller is turned on so that the brightness of the light changes accordingly. Is a light sensor, or in the case of an audio device, the voice output is output, but if the response is controlled by a control code, the voice output is stopped (power off). Can be.

FIG. 6 illustrates a circuit capable of selectively utilizing the above two embodiments. As shown in FIG. 6, the reaction detector 21 detects a response of a control target device as a change in brightness of light. The optical sensor Q1 input to the CPU 15, the microphone MIC input to the CPU 15 by sensing the response of the control target device as a change in the voice signal, and under the control of the CPU 15 It consists of an optical sensor selection switch means SW1 and a microphone selection switch means SW2 for selecting the optical sensor Q1 or the microphone MIC, and R1, R2 and R3 are resistors, Vdd is a power supply, and Q2 is an electric field effect. Transistor.

Meanwhile, the control code selection operation of the integrated remote controller of the present invention configured as described above will be described with reference to FIGS. 4 and 5 and FIG. 6 as follows.

When the user presses the key matrix unit 11 to control a home appliance of a desired company, the key signal selected and output from the key matrix unit 11 is temporarily stored in the RAM 16, decoded, and the pressed key is searched. It is determined whether it is a setting key or a preset control code output key, and if it is a general control code output key, code information corresponding to a control code which is already set is read from the ROM and output through the control signal output unit 17. Then exit.

However, when the search setting key unit 18 is pressed, a representative control code of each device according to the time information set by the timer unit 12, for example, a representative control code corresponding to the volume key of the power tee of the TV or the audio device. The key code (power key code) corresponding to the first device is read out as a test control code and output through the control signal output unit 17, and then the device waits for a reaction.

In this case, it is convenient to use a control key code for an audio device and a power on / off control key code for a video device.

As a result of outputting the test control code as described above, if the device to be controlled reacts, the reaction detecting unit 21 detects this and inputs a detection signal to the CPU 15, and the device does not respond. If not, the key code corresponding to the second device is read as a test control code and output through the output unit 17, and then the device waits for the reaction of the device. The control code (n test control codes) is continuously executed.

If the response of the device is not detected even if the output of the last test control code does not have a matching code, it is displayed through the display unit 19 and then terminated.

However, if the signal to be controlled by the reaction detection unit 21 is input to the CPU 15 in response to the code during the test control code output described above, a group of codes represented by the representative control code at that time is received. The control code is determined by determining that the code matches the receiver, and the display unit 19 indicates that the code is selected.

For example, if the TV matches the control code, the user turns the TV on, brings the integrated remote control transmitter closer to the TV, and presses the navigation setup key to start outputting the test control code. Will be.

At this time, the CPU 15 outputs a control signal from the video selection port VIDEO to turn on the optical sensor selection switch means SW1 of the reaction detection unit 21, and outputs a control signal from the audio selection port AUDIO to the microphone. The reaction detecting unit 21 is controlled in a state where the selection switch means SW2 is turned off.

When the TV is turned off in this state, since the light of the TV image detected by the optical sensor Q1 is removed, the optical sensor Q1 is turned off so that the reception signal of the interrupt port INT of the CPU 15 is in a high state. At this point, the CPU 15 determines that the control codes match, and sets and registers the code as a remote control code of the TV.

As another example, when the control code is matched with an audio device, when the user turns on the audio device and moves the integrated remote control transmitter to the audio device and presses the search setting key, it starts to output the test control code. At this point the mute operation of the audio will be performed.

At this time, the CPU 15 outputs a control signal from the video selection port VIDEO to turn off the optical sensor selection switch means SW1 of the reaction detection unit 21, and outputs a control signal from the audio selection port AUDIO to the microphone. The reaction detecting unit 21 is controlled with the selected TM position means SW2 turned on.

In this state, when the mute operation of the audio device is performed, the audio signal of the audio device detected by the microphone (MIC) is removed, so that the audio signal amplified by the field effect transistor Q2 and input to the CPU 15 is cut off. Therefore, at this seam allowance, the CPU 15 determines that the control codes match, and sets and registers the code as the remote control mode of the audio device.

As described above, the representative control code of each company outputted by the search setting key unit included in the remote control transmitter is visually checked through the display unit, so that the user can automatically select and set the remote control code of the desired product, thereby increasing the reliability of the product. There is an effect to be improved.

In addition, since the remote control transmitter itself senses the response of the device to be controlled, and determines the match, and set the control code to match, there is an effect that can conveniently and easily match the control system between the remote control transceiver.
