1 is a flowchart illustrating a method for establishing a remote signal channel according to an embodiment of the disclosed technology. Referring to FIG. 1, the method for setting a remote signal channel includes setting a channel frequency 110, generating a sampling frequency 120, and transmitting a remote signal channel frequency 130. In step 110, the transmitter sets a channel frequency. The transmitter is a terminal that later sends a remote signal to the receiver. The receiver receives a remote signal from the transmitter and performs the remote operation accordingly.

Meanwhile, the channel frequency set by the transmitter includes a plurality of frequencies stored in the transmitter. One of these frequencies is set as the channel frequency. The plurality of frequencies are different values and exist as many as the number supported by the transmitter. For example, the channel frequency can be any one of 10 multiple frequencies from 100 KHz to 0.1 increments of 100KHz, 100.1KHz, 100.2KHz, 100.3KHz, 100.4KHz, 100.5KHz, 100.6KHz, 100.7KHz, 100.8KHz and 100.9KHz. Can be. As another example, the channel frequency may be any one of five plural frequencies 200KHz, 199KHz, 198KHz, 197KHz, and 196KHz, which decrease from 1 to 200KHz. As described above, when any one of the plurality of frequencies is set as the channel frequency, the transmitter performs step 120.

In step 120, a sampling frequency is generated. The sampling frequency is generated by a predetermined method using one or more of a unique number of a transmitter or a receiver. For example, the unique number may be a serial number of a transmitter or receiver or a predetermined number assigned by a user. In generating such a sampling frequency, a sampling frequency calculation formula included in a predetermined method of generating a sampling frequency will be described below.

  ----------------------------------------

  <Sampling frequency formula>

  digit [0] = g_Sid% 10;

  digit [1] = (g_Sid / 10)% 10;

  digit [2] = (g_Sid / 100)% 10;

  f2_index = (g_Sid + g_FrequencyId)% 20;

  f3_index = (19 * digit [2] + 18 * digit [1] + 17 * digit [0] + 16 * g_FrequencyId)% 20;

  if (f2_index == f3_index)

  {

if (f2_index <19)

f3_index = f2_index + 1;

else

         f3_index = f2_index-7;

   }

     ----------------------------------------

In the above formula, g_Sid is more than 3 digits of remote control set serial number, digit [0] is one digit of remote control set serial number, digit [1] is 10 digits of remote control set serial number, and digit [2] is remote. One hundred digits of the control set serial number, g_FrequencyId is the channel selection number (one of 1 to 10), f2_index is the second natural frequency (one of 0 to 19), and f3_index is the third natural frequency (one of 0 to 19) . According to the above calculation formula, since the sampling frequency has little chance of colliding with the frequency of the apparatus used in another place at the same time, the frequency has an effect of preventing distortion or cancellation.

In operation 120, a random number may be used as a method of generating a sampling frequency. Since the random number is not periodic and is not determined by any probability, it is possible to generate a unique frequency that does not overlap another frequency by generating a sampling frequency using the random number. For example, the sampling frequency generated by using a random number may be a random number generated by using one or more unique numbers of a transmitter or a receiver and may use the generated random number. As such, the sampling frequency generated by using the random number has little chance of colliding with another frequency, thereby providing an effect of preventing distortion or cancellation of the frequency.

In step 130, the remote signal channel frequency is transmitted. The remote signal channel frequency includes the channel frequency set in step 110 and the sampling frequency generated in step 120. In step 130, the transmitter transmits the remote signal channel frequency to the receiver. In performing step 130, one embodiment of the disclosed technique includes using pairing. Pairing is a method of connecting a transmitter and a receiver by wire to transfer a preset setting or operation at the transmitter to the receiver. That is, pairing allows the transmitter and the receiver to share the same frequency. By performing the above steps, the transmitter and the receiver establish a remote signal channel for performing a remote operation.

Meanwhile, an embodiment of the disclosed technology shares a remote signal channel frequency between a transmitter and a receiver for the purpose of preventing distortion or cancellation of frequency and accurately performing remote operation. That is, although the above object is achieved by generating the sampling frequency, in order to cope with a case where frequency distortion or offset occurs, the method further includes a step of receiving a response to the remote signal and responding to the response. Additional steps will be described later with reference to FIG. 3.

2 is a block diagram of an apparatus for establishing a remote signal channel according to an embodiment of the disclosed technology. Referring to FIG. 2, the apparatus for setting a remote signal channel includes a transmitter 210 and a receiver 220. The transmitter 210 sets a channel frequency. As described above with reference to FIG. 1, the transmitter 210 sets a channel frequency using one of a plurality of channels. Therefore, the transmitter 210 stores the plurality of channels in advance. For example, the transmitter 210 may store five channels and use one selected channel among the five channels as the channel frequency of the remote signal channel setting apparatus. For reference, the number of the plurality of channels can be understood by those skilled in the art that the number of channels is flexible as provided by the transmitter or can be set by the user.

In addition, the transmitter 210 generates a sampling frequency. The sampling frequency is to prevent distortion or cancellation of the frequency when the previously set channel frequency is used in another device. Therefore, the values used for the sampling frequency do not overlap. That is, the frequency generated using the unique number of the transmitter 210 or the receiver 220. Unique numbers are numbers that do not overlap. For example, the sampling frequency generated using the unique number may be generated using the serial number of the transmitter 210 or the receiver 220. As another example, the sampling frequency generated using the unique number may be generated using a random number. As described above, the transmitter 210 transmits the set channel frequency and the generated sampling frequency to the receiver 220 as the remote signal channel frequency.

Meanwhile, the receiver 220 receives the remote signal channel frequency previously transmitted by the transmitter 210. In the receiving method, the transmitter and the receiver use pairing as shown in FIG. 2. Pairing connects the transmitter and the receiver by wire, and transmits a remote signal channel frequency from the transmitter to the receiver. Through this process, the transmitter 210 and the receiver 220 are made of a device sharing one remote signal channel frequency, and perform a remote operation later. In addition, the transmitter 210 may be paired with the second and third receivers to receive different remote signals, and may be used as a device for performing a corresponding remote operation. An apparatus for receiving a remote signal from different receivers will be described later with reference to FIG. 4.

In addition, the apparatus for setting a remote signal channel according to an embodiment of the disclosed technology further performs the following process as a countermeasure against damage or cancellation of frequencies that may occur. Referring to FIG. 2 again, the transmitter 210 transmits a remote signal to the receiver 220 through a remote signal channel frequency. Since the remote signal channel frequency is shared through pairing, the remote signal is wirelessly transmitted between a transmitter and a receiver located at a remote location. In addition, the transmitter 210 receives a response of whether the receiver 220 receives a remote signal and performs a remote operation. On the contrary, the receiver 220 receives a remote signal from the transmitter 210 to perform a remote operation, and transmits a response to the remote signal to the transmitter 210. If a remote signal transmitted by the transmitter 210 is missing or a response to the remote signal transmitted by the receiver 220 is missing, that is, the transmitter 210 does not receive a response from the receiver 220. The transmitter 210 determines that the receiver 220 does not perform a remote operation. The remote signal is transmitted again to perform accurate remote operation. The retransmitted remote signal is a remodulation of the previously transmitted remote signal. The modulated remote signal is modulated according to the reference increment of the transmitter or receiver. The reference increment uses the unique number of the transmitter or receiver. As described above with reference to FIG. 1, the unique number uses a serial number or a random number of a transmitter or a receiver. The modulated remote signal is transmitted to the receiver 220 again, the receiver 220 performs a remote operation, and transmits a response to the remote signal to the transmitter 210. The apparatus for setting a remote signal channel according to an embodiment of the disclosed technology provides an effect of allowing a receiver to perform accurate remote operation by preventing damage or offset due to a frequency used to be performed at another adjacent place at the same time. .

3 is a flow chart for remote signal channel establishment and remote signal transmission in accordance with one embodiment of the disclosed technology. Referring to FIG. 3, the method for setting a remote signal channel frequency may include setting a channel frequency 310, generating a sampling frequency 320, and transmitting a remote signal channel frequency as described above with reference to FIG. 1. 330). In addition, the method further includes a step 340 of checking whether the remote operation has been performed in the receiver. Steps 310 to 330 correspond to steps 110 to 130 of FIG. 1, and thus, detailed description of step 340 will be given below. In step 340, a transmitter and a receiver sharing one remote signal channel frequency process remote operation according to a remote signal. In step 340, the transmitter transmits the remote signal to the receiver through the connected remote signal channel frequency. And the response according to the transmitted remote signal is received. The remote signal is for the receiver to perform the remote operation. The remote signal is transmitted from the transmitter to the receiver through the previously connected remote signal channel frequency. And the transmitter that has transmitted the remote signal is to receive a response to the remote signal from the receiver. For example, the remote signal may be a command that instructs the receiver to perform a remote task, and the response may be a feedback that informs the transmitter that the receiver performed the remote task and performed the remote task.

On the other hand, the receiver receives a remote signal from the transmitter through the connected remote signal channel frequency. Then perform remote operation according to the remote signal. In addition, a response to the received remote signal is transmitted to the transmitter. The response is a kind of feedback to the remote signal. For example, the response may be a signal for confirming that the remote operation is performed according to the remote signal.

Meanwhile, the step of receiving the response has two cases. The first case is when the response to the remote signal is sent from the receiver. The second case is when no response is sent to the remote signal from the receiver. In the first case, the transmitter determines that the receiver has performed the remote signal and terminates the remote operation. However, in the second case, the transmitter does not receive a response from the receiver, and therefore cannot determine whether to perform remote operation. That is, the remote signal may be distorted or canceled by another signal. Therefore, in one embodiment of the disclosed technique, the transmitter performs the following procedure to correctly allow the receiver to perform the remote operation.

If the transmitter does not receive a response to the remote signal from the receiver, the transmitter retransmits the remote signal modulated according to the reference increment. The reference increment is set according to the unique number of the transmitter or receiver. In one embodiment of the disclosed technique, the remote signal channel frequency changed according to this reference increment is called the second remote signal channel frequency. For example, the second remote signal channel frequency may be obtained by modulating the first remote signal channel frequency according to either serial number of the transmitter or the receiver. As another example, the second remote signal channel frequency may be obtained by modulating the first remote signal channel frequency according to the serial number of either the transmitter or the receiver. In this process, the remote signal frequency changed according to the reference increment connects the transmitter and the receiver again, and transmits the remote signal along the connected channel frequency. In this process, the number of reference increments and the time for waiting for a response to a remote signal may be set in advance or set by a user in one embodiment of the disclosed technology. If you grow up, you will understand. In addition, an embodiment of the disclosed technology due to the above process solves the problem caused by the damage or cancellation of the remote signal, and provides the effect of performing the remote operation correctly.

4 is a diagram for transmitting a remote signal in a remote signal channel setting apparatus according to an embodiment of the disclosed technology. Referring to FIG. 4, in the remote signal channel setting apparatus, a plurality of receivers may be connected to a transmitter, respectively. For the detailed description of an embodiment of the disclosed technique as shown in FIG. 4, the receivers connected to the transmitter are referred to as a first receiver and a second receiver, respectively. The first receiver and the second receiver each share a unique frequency with the transmitter. In other words, they share the frequencies set so that they do not interfere with each other's remote operation. Therefore, even when a plurality of receivers are connected to one transmitter, each receiver receives an undamaged remote signal and provides an effect of accurately performing the remote operation accordingly.

Meanwhile, although not shown in the drawings, a detailed description of a probability that a remote signal channel frequency collides with another frequency used in the apparatus and method for setting a remote signal channel according to an embodiment of the disclosed technology is as follows. Assume A, B and C as follows for detailed description according to one embodiment of the disclosed technology. A is a collision probability of a channel frequency set by selecting one of ten channels stored in the transmitter 210. B is a collision probability of a sampling frequency using a unique number of a transmitter or a receiver. For convenience of calculation, the number is 20. C is the collision probability of the sampling frequency using the unique number of the transmitter or the receiver. Since B was selected one of 20, 19 unique numbers except 1 are used. It has a collision probability of (1/10) * (1/20) * (1/19), which is a product of collision probabilities of A, B, and C, respectively. Also, considering the case of selecting the same channel at the same time, the collision probability has a probability of about 1 / 328,320,000. Conversely, the apparatus and method for setting a remote signal channel according to an embodiment of the disclosed technology uses the channel frequency having the extremely rare collision probability as described above, thereby providing an effect of accurately performing the remote operation.
