The present invention relates to a remote control code copying / relay device and a method thereof, and more particularly, to copy a code of a plurality of remote controls for remote control of each home appliance, and to store them in a computer, and to control commands remotely through the Internet from the outside. The present invention relates to a remote control code copy / relay device and a method for automatically controlling a product by extracting a prestored copy code and generating an infrared signal when a user inputs a command by directly operating a computer.

In general, infrared (IR) signals have a merit that they can transmit a large amount of data at a relatively low cost without any confusion, and many devices, especially home appliances, which users have to control from time to time, mostly use a wireless remote controller using IR signals. I use it. The IR signal is a very excellent technology except for the shortcoming of visible distance communication, and there is no other coping technology at present for use in home appliances. This superiority of IR has led to the development of the interface of most home appliances around the IR wireless remote control, which is why today, homes usually have about 10 IR wireless remote control. With the development of home automation and home networks, the necessity of controlling various home appliances not only in the house but also outside the house is increasing. This control method (controllable outside the home) improves the use efficiency of home appliances and makes the user's life easier. In addition, by allowing the experienced user to control the home appliances in the home from the outside to promote the use of home appliances safely even if there is an immature use (child, elderly, disabled) in the family.

As is well known, to control the use of home appliances outside the home, all home appliances must be connected to a control device that can communicate with the outside world. Looking at the problem when trying to connect a home appliance to a control device that can communicate with the outside as follows.

1) Most home appliances currently in production do not have a separate remote control method besides IR communication method.

2) Control codes are different for each product.

3) The control codes used in the product are not standardized.

Based on the problems listed above, to connect the currently configured household appliances (currently in use) to the controller most easily, inexpensively and quickly, the interface used by the current household appliances is used as it is. In this way, all existing home appliances can be used as they are, which enables very economical and quick installation and use.

To realize such a configuration, it is necessary to know the codes of all home appliances and input them into a computer (control device). But in reality, collecting and entering all the code from a number of manufacturers is a very difficult task and requires expert skill.

Therefore, the present invention collects all the codes of the remote control manufacturer that occurs when controlling all the conventional home appliances as described above (outside the house) when connecting to the controller that can communicate with the controller and home appliances to enter the controller As a solution to all the problems that occur,

And a power supply unit 280 for supplying driving power, and a control signal for transmitting an infrared signal output from the central processing unit 240 to the transmitting unit installed at a long distance.

"Remote control code copy / relay method" according to the present invention, as shown in Figure 5, the step of confirming the connection with the host after the initialization operation (S110 ~ S120); Determining a current operation mode when the connection is made with the host (S130); Converting the received infrared signal into a digital signal and transmitting the received infrared signal to the host when the operation mode is the infrared code copy mode (S140 to S160); Receiving a control command from the host when the operation mode is an infrared transmission mode (S170); In operation S180, an infrared signal is generated and transmitted in response to the received control command.

When the remote control code copy / relay device and the method according to the present invention configured and made as described above in detail.

First, in order to control a specific product (particularly, home appliance) 100 owned by the user remotely from outside the home or integratedly through the computer 300, codes of various remote controllers corresponding to the specific product 100 may be used. Make a copy through the remote control code copy / repeater (200).

The remote control code will now be described with reference to FIGS. 3A to 3D.

Most IR remote controls use frequencies of 38 kHz (26.315 kHz) or 56 kHz (17.857 kHz) as carrier signals. There are remote controls that use some 75 ㎑ signals, but only a few are. The IR remote controller receives the light blinking signal of the infrared light emitting diode and the infrared light emitting diode receives the signal to reproduce the signal. This operation consumes a lot of energy depending on the lighting time of the light emitting diode. Since most IR remote controllers use a built-in battery, a large amount of energy consumes inconvenience for the user. To compensate for this problem, the IR remote controller minimizes the ON time within the same frequency, that is, the time that the LED is turned on. One cycle of 38 Hz is 26.315 Hz, as shown in FIG. 3B. If the signal is normal, the ON time and the OFF time are the same and are 13.1575㎲ respectively. On the IR remote control, however, the ON time is 5 ms and the OFF time is 21 ms. This is the same even when using 56 kHz of the carrier signal. The IR remote turns on the infrared light emitting diode at a constant carrier frequency. This operation maintains at least 600 Hz, during which time the infrared light-emitting diode flashes approximately 22 to 33 times depending on the carrier frequency. This continuous flashing is regarded as a signal. The relationship between the number of signals and the arrangement (see Figs. 3B to 3D) becomes the code of the IR remote control.

When copying the remote control code, the remote control code copy / repeater 200 performs initialization as shown in FIG. 5 (S110), checks a connection state with the host 300 (S120), and checks with the host 300. If connected, the operation mode (copy mode / transmission mode) is searched for (S130). When the search result is in the copy mode, an infrared code is received (S140). When the infrared code is received, the received analog infrared signal is converted into a digital signal corresponding thereto (S150). Next, the digitally converted infrared code data is transmitted to the host 300 to transmit the host 300. To store it in the memory (S160).

In more detail, the infrared code copying operation selects a specific product (for example, a TV) according to a user's selection in an initial menu, and the basic elements necessary for controlling the TV are displayed on the screen. Next, direct the front (infrared light transmitting portion) of the IR remote control for the TV to the light receiving window 210 of the infrared code copying / repeater 200, and move the cursor to select a menu. Here, the light receiving window 210 prevents the light receiving diode from being saturated due to natural light and becomes inoperable, and generally uses a plastic-based plate material coated with a red pigment. Dedicated filters allow operation even in the worst operating conditions.

Thereafter, when the corresponding switch of the IR remote control for the TV according to the selected menu is pressed, an infrared signal is generated, and the infrared signal incident through the light receiving window 210 is received by the auxiliary light receiving unit 220 and the transmitter 230. In general, the length of one code (one command) generated by the IR remote control is usually 50㎳, so the same signal is repeatedly transmitted several times while the user presses a switch on the remote control. The remote control code copy / repeater 200 copies the input signal as it is and transmits it to the host 300. Here, the remote control code copy / repeater 200 has a basic mode (standby state) set to a copy mode, so that a user does not need a separate operation for inputting a code of an infrared remote controller.

Next, the auxiliary light receiving unit 220 receives the transmitted light signal (IR remote control output signal) incident through the light receiving window 210, converts into a digital signal and outputs it. The auxiliary light receiving unit 200 ignores the carrier signal among the signals of the light emitting diode and receives only a signal of 600 Hz or more. This data is used to measure the shape of the output code of the remote control or the size of the entire signal when copying the IR remote control signal.

In addition, the transceiver 230 is a module that is a combination of the IR transmission and reception function receives a signal of the IR remote control incident through the light receiving window 210 in a carrier unit and outputs it as a digital signal. This data accurately analyzes the IR remote control signal.

Data output from the auxiliary light receiving unit 220 and the transmitter / receiver 230 is input to the central processing unit 240, and the central processing unit 240 is a red light emitting diode RED through the status display unit 260 in the copy mode. ) To emit light so that the user visually recognizes the copy mode. In addition, the central processing unit 240 transmits the input infrared code data to the host, that is, the computer 300 through the communication interface 250 to store it in the memory of the computer 300.

The central processing unit 240 uses the PIC16F73. The PIC16F73 is a one-chip microprocessor with internal ROM and RAM. There are three input / output switching ports of RA, RB and RC, and the clock can be up to DC-20MHz. A transmitter / receiver 230, an auxiliary receiver 230, a status display unit 260, a plurality of transmitters 271 to 274, a communication interface 250, and an RS485 290 are connected to the processor. The digital IR signal input by the transceiver 230 is input to the RC1 port. When a signal is input, the processor outputs a high signal to the status display output port RB0 to inform the user that the current state is copy mode. When an IR signal is input to the RC1 port, the processor measures the high-low time of the signal. This measurement is taken continuously while the signal is coming in. The measured value is stored in the S-Memory in the processor and transmitted to the computer 300 via the communication interface 250 through the RC6 port. The same signal is input to RC4. However, the signal input to RC4 is a signal without a carrier component and only a code. This signal is used to measure the overall length of the cord and the shape of the cord.

The computer 300 stores the transmitted remote control code in the memory. Of course, when storing the remote control code, the product name, the information of the pressed switch of the product, and the infrared code information are stored together.

Next, when a user transmits a control command to control a specific product 100 installed in the home through the Internet 400 remotely (outside the house), the computer 300 sends infrared code data corresponding to the control command. Withdraw from the memory and transmits to the remote control code copy / repeater 200.

Then, as shown in FIG. 5, the remote control code copy / repeater 200 switches a mode to a transmission mode, receives a control command transmitted from the computer 300 (S170), and then transmits 271 to 274. ) To transmit the infrared signal corresponding to the specific product (S180).

That is, when the signal transmitted from the computer 300 through the RC7 port is input to the central processing unit 240 in the remote control code copy / repeater 200 when the remote control code is transmitted, the high-low length (time) of the signal is input. Therefore, the light emitting diodes (RB2, RB3, RB4, RB5 ports) flash. At this time, the RB1 port indicates that the current state is a light-transmissible state and is inverted from the copying signal RB0. The state display unit 260 turns on the green light emitting diode (GREEN) to indicate that the infrared transmission state. In this case, the control ability of a single home light emitting diode is the same as that of an IR remote control, and the installation of multiple light emitting diodes is impossible to control when the location of home appliances is out of view. This is to allow control.

On the other hand, there is no problem when the specific product to be controlled is an area that can be controlled by the infrared signal transmitted from the transmitters 271 to 274 embedded in the remote control code copy / relay 200. However, when a specific product exists outside the control area of the transmitters 271 to 274, for example, when a specific product exists outside the control area of the transmitters 271 to 274 due to a different floor or a different room, the transmitter It is not possible to control specific products using (271 to 274).

In order to improve this disadvantage, in the present invention, the RS485 290 is used to control a specific product. RS485 is the most long-distance communication method among two line communication, and it can be used for IR control (light-emitting diode blinking) directly without processing, so no additional circuit is required.

In addition, the power supply unit 280 receives a general commercial AC power (AC 220V) is converted to a DC power supply (DC5V) and serves to supply driving power to each block that requires power.

According to the present invention as described above, there is an advantage that can easily copy the code of a plurality of remote control for remote control of each home appliance to be stored in a computer.

In addition, when a control command is input from the outside through the Internet remotely or a user directly inputs a command by operating a computer, the stored copy code is extracted and an infrared signal is generated to automatically control the corresponding product.
