Abstract

The present invention relates to the reception of a remote control, in particular, when the remote control receiver and the remote control of the device operated by the remote control does not match; or in the remote control consisting of a specification and the device, there is a restriction of use due to the loss of the remote control When the remote control of any other device can be used to change the unique code of the remote control receiver.

If you lose the remote control provided with the device and one specification, or if you have too many remote controls and want to integrate them into one remote control, simply change the unique code of the remote control receiver and save it. This can be done by using code, which is very convenient and useful.

Implementation method of remote control receiver operated by arbitrary remote control

Drafting is a waveform diagram of a typical remote control,

2 is a schematic diagram of a remote control receiver;

3 is a flowchart illustrating a method of changing a code of a remote controller receiver for implementing a remote controller receiver operated by an optional remote controller of the present invention.

The present invention relates to a receiving unit of the remote control, in particular, when the device operated by the remote control and the remote control does not match; or in the remote control consisting of a specification and the device, there is a limit of use due to the loss of the remote control; It is possible to change the code of the remote control receiver in order to use the remote control.

That is, the present invention relates to a remote control receiver that allows a user to change a unique code of the remote control receiver using any input remote controller irrespective of the transmitter of the remote controller.

As the society has become more automated and diversified, the use of remote controllers of many industrial devices and home appliances has become commonplace. Therefore, users have various types of remote controllers, which causes a lot of confusion. In other words, when using a remote control that is broken or when the battery is exhausted, or when using a remote control that is attached to another device, the user does not operate the desired device.

In general, an existing remote control receiver has a type of input pulse specified at the time of shipment of a product and is not set to be changed, so it must be used with a remote controller shipped together. Therefore, when the first remote control is lost, a new remote control or a manual operation only has a disadvantage.

On the other hand, some of the remote control has a few unique codes, it was to find the code that matches the device and set the operating state, but this is a burden to buy a new remote control, users who own a lot of remote control It was very uncomfortable because it could lead to confusion.

In a wireless remote controller, an infrared diode is turned on or off to generate an optical signal, and the optical signal is received by an infrared detector installed in a receiver main body such as a television and a game machine and converted into an electronic signal.

As described above, a transmission signal waveform diagram of a general remote controller may be illustrated as in FIG.

The transmission signal of the remote controller includes a leader code (1), a unique code 16 bits (custom code 16 bits = custom code 8 bits + inverted custom code 8 bits; 2 + 2), and a data code 16 bits (data code 16 bits = data code). It consists of 8bit + inverted data code 8bit; 3 + 3) and continuous code4. Each bit of the unique code (2) and the data code (3) is divided into '0' (1.25ms) and '1' (2.5ms) as a period of one cycle. The reader code 1 and the continuous code 4 are longer than the bits of the unique code 2 and the data code 3, with periods of (13.5 ms) and (11.25 ms), respectively.

On the other hand, the built-in remote controller receiver generates an interrupt at regular time intervals when a signal is received from the remote controller, or reads the signal by generating an interrupt at the falling edge of each code.

At this time, the remote control receiver in the device extracts only a unique code (custom code; 2) from the transmission signal of the remote control, and compares it with its own code, and then compares the data code to operate the device. If it doesn't work.

Therefore, it is important to match the unique code for recognizing the operation signal of the remote control, and any remote control can be used if only the unique code of the remote control receiver in the device can be changed.

When described in detail with reference to the drawings, the schematic diagram of the remote control receiver for the implementation of the present invention can be shown as a second diagram,

An infrared light receiving sensor 1 which receives a transmission signal of a remote controller, a microprocessor 2 which compares whether a signal input to the infrared light receiving sensor 1 matches a signal of a device, and stores a variable remote control signal The memory 3 is comprised.

In the device configured as described above, the infrared light receiving sensor 1 receives the transmission signal of the remote controller and inputs it to the microprocessor 2, and the microprocessor 2 receives the signal input from the infrared light receiving sensor 1 as its own. Compare and match with the signal stored in memory (3) to operate the instrument. At this time, if the existing signal stored in the memory and the signal input to the infrared light-receiving sensor 1 does not match, the device does not work; at this time, the comparing part compares only the unique code of each signal. Therefore, if the unique code does not match, it is input whether or not to change to the newly inputted unique code, if changed, the changed code is stored in the memory (3), and then the signal is compared using the changed code. In this case, if the data codes do not match, the device may not work or malfunction. If the data codes do not match after comparison, the data codes can be changed and stored in memory.

When described in detail using a flow chart to help understand, the operation flowchart of the method of changing the code of the remote control receiver for implementing a remote control receiver operated by any remote control of the present invention can be shown as shown in FIG.

When the transmission signal of the remote controller is received in the remote control receiver (step S1), the microprocessor determines whether or not the code matches the unique code of the remote controller receiver (step S2), and if it matches, the device is operated (step S9). A message asking whether to change the unique code is output (step S3). At this time, if you don't want to change the device, the device will stop working after a certain time without any action.If you want to change the code, press any button again to save the changed new code in memory. The device is operated by comparison with the code (step S4). At this time, it is again determined whether the data code matches (step S5), and if it matches, the next step is to determine whether the unique code matches (step S8). If not, a message asking whether to change the data code is output (step S6), and the data code is changed in the same manner as that of changing the unique code (step S7). In this state, if the user presses any button, it is determined once again whether the unique code matches (step S8), and if it matches, the device is operated (step S9), and if it does not match, the unique code can be changed. (Step S3) Return.

As described above, the present invention can be achieved by simply changing the unique code of the remote control receiver when the user loses the remote control provided in one specification or the user who has too many remote controls and wants to use it as a single remote control. It can be very convenient and useful.
