Abstract

PURPOSE: An apparatus and method for searching for and setting up a control frequency in a remote controller is provided to easily and rapidly search for a control frequency code to remotely control an equipment produced by a brand using the brand initial of the equipment. CONSTITUTION: In the idle mode of an initial state maintaining an enable state, a control part scans key signal input from a keypad part(S301-S303) and judges whether the input of a key signal is detected(S304). If the input of a key signal is detected, the control part judges whether the detected key signal is an arbitrary key signal to enter a control frequency code setup mode for an arbitrary equipment to be controlled(S305). If it is judged that an arbitrary key signal to enter the control frequency code setup mode for an arbitrary equipment to be controlled is inputted, the control part judges whether the arbitrary key appointed to enter the control frequency code setup mode has been pushed for more than 3 seconds(S307). In case that it is judged that the arbitrary key appointed to enter the control frequency code setup mode has been pushed for more than 3 seconds, the control part enters the control frequency code setup mode and lights up the LED2 of a display part to inform the user of approach to the control frequency code setup mode(S308).

Description

CONTROL FREQUENCY SEARCH AND SET UP APPARATUS OF UNIVERSAL REMOTE CONTROLLER AND METHOD THEREOF}

The present invention relates to a remote control device, and more particularly, to set a control frequency code corresponding to various controlled devices to be controlled before using the remote control through a brand initial of the manufacturer of the controlled device. The present invention relates to a control frequency search setting device and a method of a universal remote controller.

In general, in order to lead a variety of cultural and pleasant lives according to the improvement of household income level, television (TV), video cassette recorder (VCR), audio, air conditioner, cable TV, satellite broadcasting converter (SAT), fans, and a variety of other electronics, which are manufactured and manufactured by manufacturers that enable remote control through the transmission of radio-controlled frequencies to provide consumers with more convenient use. have.

For example, power on / off, channel up / down, volume up / down, and selection control of various functions and playback of video cassette recorders, recording operation, caption operation, and selection control of a television are performed. In this case, the user can control the desired function by using a remote controller, a remote controller, without directly manipulating these electronic products.

However, each brand (manufacturer) that produces the electronic products are set differently the control frequency code of the remote control to prevent the malfunction of the other controlled device for each controlled device, and used by the brand (manufacturer) The control frequency code is also set differently.

Accordingly, when a plurality of controlled devices are provided, a remote controller corresponding to the controller device exists in each, so that a user should be familiar with how to use the remote controller for each brand and controlled device, and correspond to each controlled device. There is a cumbersome problem of selecting a desired function of the controlled device using the remote control.

In addition, there is a problem that care must be taken not to lose after using any remote control.

In order to solve this problem, a universal remote control has been developed and used to control the integrated controller of each brand with one remote controller.

In general, the controlled devices used in the home have at least one different brand of controlled device according to the user's preference, performance and characteristics, and each brand has a unique function of the frequency code applied to the remote controller. Each brand is setting its own frequency code to prevent malfunction with other controlled devices.

Therefore, the frequency code data of the controller of each brand is set in the internal or external memory of the microprocessor of the universal remote controller.

Therefore, among the numerous frequency bands and data codes for each brand and each controlled device stored in the microprocessor internal or external memory of the universal remote controller, a method for efficiently finding and setting a frequency code suitable for the controlled device (electronic product) to be used currently. Research on the field continues.

For example, the US patent US Pat. No. 4,703,359 is equipped with an identifier mode on the universal remote control, and the user selects the selector button of the identifier mode until the desired code is operated. If it finds the frequency code that the controlled device wants to operate while pressing, it turns off the button of the identifier mode and sets the control frequency code for the corresponding controlled device.

Also, in the case of US Patent No. 4,774,511, a control frequency code adopted by a manufacturer is formed into a signal group and assigned to one numeric key, so that when the user presses any numeric key, It is a method to automatically scan the information formed into a group to select the control frequency code for the corresponding controlled device. In the case of US patent US Pat. No. 5,872,562, each product model of the manufacturer and the manufacturer By setting constant control frequency codes for each user, the user directly inputs these codes in the setting mode.

As described above, the conventional method of setting the control frequency code for an arbitrary controlled device in the universal remote controller is familiar with the function of the universal remote controller due to the complexity of executing several key selections, mode selections, and repetitive key input. In the case of a user who does not have a problem, there is a problem in that a control frequency code matching to a desired controlled device cannot be set normally.

In addition, since it is necessary to find the code number of the brand and model of the controlled device to set the control frequency code in the user manual distributed to the user, and input the information directly, there is a problem in setting the control frequency code.

In addition, there is a method of inputting the alphabetical characters of the brand (manufacturer) of the controlled device, but in this case, for example, assuming that a control frequency code is input for a TV of Samsung Electronics, the remote control user selects the After selecting, Samsung's brand letters “S, A, M, S, U, N, G” must be entered in sequence so that it takes too much time to set the control frequency code and takes up a lot of memory space. There is this.

In addition, when the English of the manufacturer's brand is assigned to one key (number key 1), such as 'ABC', a problem occurs in that the control frequency code cannot be set in the controlled device.

An object of the present invention for solving the above problems is to quickly and easily retrieve and control the control frequency code for remote control of each controlled controller produced by each brand from the memory area using the brand initial of the controlled controller The frequency code is set.

That is, the user automatically selects only one letter of the manufacturer name of the manufacturer producing the controller among the letters (English alphabet) marked on the numeric keys of the remote controller to automatically control the control frequency code for the controller. It is set to.

For example, if there are three selector control keys such as TV, VCR, SAT, etc. on the remote controller, the control frequency codes for all the controlled devices are sequentially transmitted for each brand.

In addition, without entering any control device by using a control key selection key (for example, TV, VCR, SAT, etc.) included in the remote controller, only one setting key is input to enter the control mode code setting mode. This is to provide a differentiation from the existing brand scanning method.

In addition, the built-in backup function of the control frequency code is built in, so that when the replacement of the battery is completed within a certain time, the set control frequency and data code are maintained without being destroyed.

Is composed of a second function key 14.

In the case of each key having the above-described configuration, application and expansion of new functions are possible according to the developer and the designer of the program.

The configuration of the internal hardware of the remote controller provided with the above keys is as follows.

As can be seen in Figure 2, the remote control according to an embodiment of the present invention, the keypad 10 for detecting the above-described selection signal of each function key, the control unit 20, the oscillator 30, the transmitter ( 40, a power supply unit 50, a display unit 60, and a memory unit 70.

In the above, the keypad 10 includes a plurality of matrix contacts in which the X-axis and the Y-axis intersect. Each matrix contact corresponds to each key of the above-described configuration of FIG. When contacting, the voltage for selecting the corresponding contact is output by the voltage drop and applied to the control unit 20.

The control unit 20 is a microprocessor that controls the general operation of the universal remote controller. The controller 20 is a predetermined key of the keypad 10, for example, a predetermined time or more depending on a selection of a setting key in the first function key 12. Enter the setting mode of the control frequency code for any controlled device, for example, TV, VCR, SAT, AUDIO, etc., and in accordance with the brand initial selection signal input through an arbitrary numeric key in the second function key 13 Set the control frequency code for the controlled device, and if the input of key selection signal for remote control of any controlled device is detected, send the control frequency code set to the controlled device to function. Is performed.

The control unit 20 may include a first memory unit 21 for storing control frequency codes for each controlled device, for example, a TV, VCR, SAT, AUDIO, etc., as a brand initial for each manufacturer, and by a user's operation. And a second memory section 22 for storing a control frequency code for any controlled device to be search set.

The oscillator 30 allows the control unit 20 to operate, and oscillates a clock of a predetermined band to transmit a control frequency code to a controlled device for each manufacturer.

The transmitter 40 transmits a control frequency code to an arbitrary controlled device side set according to the control signal applied from the controller 20.

The transmitter 40 includes a resistor R2 for adjusting the intensity of the output control frequency, a transistor Q1 switched according to a driving signal applied through the resistor R2, and a collector of the transistor Q1. LED1 is connected to the terminal and emits light by the power supply B + supplied through the resistor R1 according to the switching operation of the transistor Q1.

The power supply unit 50 is a power supply source of the universal remote controller, and supplies the voltage of the mounted primary or secondary battery to the control unit 20 and each load side as operating power.

The power supply unit 50 includes a first capacitor C1 and a second capacitor C2 that perform charge / discharge functions by a primary battery or a secondary battery to be mounted, even when the battery is discharged. Supply power.

The display unit 60 is turned on when any button for remote control is selected for any controlled device of the keypad unit 10 or when the setting of the control frequency code is performed through the brand initial selection. Instruct

The memory unit 70 stores the control frequency codes for the controlled devices for each brand as an external expansion memory means in each address area.

In the remote controller of the present invention including the function as described above, an operation of setting a control frequency code through an initial selection of a manufacturer for any controlled device is as follows.

When the primary battery or the secondary battery is mounted in the power supply unit 50, the oscillator 30 generates a set clock to enter the operation of the controller 20 into an enable state.

The controller 20 scans the key signal input from the keypad 10 in the standby mode of the initialization state S301 in which the control state is enabled (S301) (S303), and determines whether an input of the key signal is detected. (S304).

If the determination of S304 does not detect the input of the key signal, the controller returns to S302 to continuously scan the input of the key signal as described above in the standby mode, and if the input of the key signal is detected, the detected key signal is random. In step S305, it is determined whether the control frequency code for the controlled device is input to a predetermined key, for example, a setting key signal in the first function key 12, for entering the setting mode.

If it is determined in S305 that it is not a designated key signal input for entering a control frequency code setting mode for any controlled device, any of the controlled devices currently set in the remote controller, for example, TV, VCR, The controller 20 determines that the input is a signal for controlling the functions of the SAT, the AUDIO, and the like, and the control unit 20 selects a control frequency code for controlling the function of the controlled device stored in the predetermined address area of the second memory unit 22. By accessing a frequency code corresponding to the input key and outputting it through the transmitter 40, a function desired by a user can be selected and controlled (S306).

However, if it is determined in the determination of S305 that the designated arbitrary key signal is input for entering the control frequency code setting mode for any controlled device, the predetermined arbitrary key for entering the mode is set for a predetermined time, preferably It is determined whether it is pressed for 3 seconds or more (S307).

If the designated random key for entering the mode is not pressed for a predetermined time or more in step S307, return to the process of S302 to enter the standby mode for the key input scan, and if it is determined that the specified random key is pressed for a predetermined time, The control unit 20 enters the control frequency setting mode for any controlled device and then lights up the LED2 of the display unit 60 to indicate to the user that the setting mode has been entered (S308).

As described above, when the remote controller enters the control frequency code setting mode for an arbitrary controlled device, as shown in FIGS. 4A and 4B, the key signal input of the second function key 13 is scanned. For example, it is determined whether the input of the 'ALL' signal specified by the numeric key '0' is detected (S401).

If it is determined in the determination of S401 that the input of the 'ALL' signal according to the input of the numeric key '0', all the brands for each controller already stored in the first memory unit 21 or the memory unit 70, That is, the brand initial of the manufacturer enters the control frequency code setting mode for the controlled devices of all brands that sequentially transmit control frequency codes from the data starting with 'A' to the brand initial 'Z' (S405). If the input of the ALL 'signal is not detected, it is determined whether the numeric keys 1 to 9 for selecting any brand initial have been continuously pressed for a predetermined time period, preferably 3 seconds or longer (S402).

If it is determined in step S402 that the numeric key for selecting an arbitrary brand initial is pressed for a predetermined time, the process for entering the control frequency code setting mode for each brand is performed (S403) and the number for selecting an arbitrary brand initial is performed. If it is determined that the key has not been pressed for a predetermined time or more, it enters the initial standby mode and scans the key input (S404).

In step S405, when the control frequency code setting mode for each controlled device of all brands is entered, any one setting key among all keys implemented on the remote controller pad, that is, input of a setting key for performing the code setting mode. It is determined whether this is detected (S406).

If a key input is not detected in S406, it is determined whether a predetermined time period, preferably 3 seconds, has elapsed (S413). The control mode code setting mode for the controlled device is terminated, and if the set time has not elapsed, the process returns to step S406 to continuously detect any key signal input.

As described above, when an input of a setting key designated in S406 is detected while a control frequency code setting mode for all brands of controlled devices is entered, an order and method set for setting control frequency codes for all brands of controlled devices are detected. The control frequency code is transmitted (S407).

In the process of transmitting the control frequency codes for the controlled devices of all brands in the order and manner set as described above, a key input is scanned to determine whether any key signal input accompanied by user's designation is detected (S408).

If an input of a key signal is not detected in S408, the process of S407 is repeatedly performed. If an input of any key signal is detected, any key to which the corresponding key signal is assigned, for example, a channel in the first function key 12, is detected. It is determined whether the signal is the up key (S409).

If it is detected by the input of any key specified in the determination of S409, for example, the channel up key in the first function key 12, the memory address is increased by one level from the current memory address and stored in the corresponding memory address. The control frequency code for the controlled device of the brand is sequentially transmitted (S410).

Whenever a signal of a predetermined key, for example, a channel up key, is input in step S410, the memory address is increased by one step to sequentially control frequency codes for all brands of controlled devices stored in the corresponding memory address. Send it out.

In the determination of S409, if it is not an input of any designated, e.g., channel up key signal for performing memory address increase, it is determined whether it is a signal of any designated key, e.g., a channel down key in the first function key 12. (S411).

If it is detected by the input of a predetermined key, for example, a channel down key in the first function key 12 in the determination of S411, the memory address of one step is reduced from the current memory address and all stored in the corresponding memory address. The control frequency code for the controlled device of the brand is sequentially transmitted (S412).

Each time a signal of a key designated in S412, for example, a channel down key is input, the memory address is decreased by one step to sequentially control the control frequency codes for all brands of controlled devices stored in the corresponding memory address. Send it out.

In the determination of S411, if it is not an input of any designated, for example, channel down key signal for performing memory address reduction, it is determined whether it is a signal of any designated key, for example, a volume up key in the first function key 12. (S413).

If it is detected by the input of a predetermined key, for example, a volume up key in the first function key 12 in the determination of S413, control is performed for all brands of controllers stored in the corresponding memory area from the current memory address. The frequency code is sequentially transmitted (S414).

When a signal of any key designated in S414, for example, a volume up key, is input, control frequency codes for all brands of controlled devices are sequentially transmitted from the memory address at that moment.

The process of transmitting the control frequency codes for the controlled devices of all brands stored in the memory area according to the detection of any of the above designated keys, for example, the channel up key, the channel down key, or the volume up key signal. In (S420), it is determined whether the key input is detected by continuously scanning the key input (S421), and it is determined whether the key input is detected within a predetermined time period, preferably within 3 seconds (S422), If not detected, exits the setting mode of the control frequency code for all brands of controlled devices, and if a key input is detected, a predetermined key, e.g., the first function key 12, selects whether the key selects memory address increment. It is determined whether the channel up key is input (S423).

In step S423, if a predetermined random key for increasing the memory address, for example, is detected as an input of a channel up key in the first function key 12, the memory address is increased by one step from the current memory address and stored in the corresponding memory address. The control frequency codes for the controlled devices of all brands are sequentially transmitted (S424).

In the determination of S423, if it is not an input of any designated, for example, channel up key signal for performing the memory address increase, it is determined whether it is a signal of any designated key, for example, a channel down key in the first function key 12. (S425).

If it is detected by the input of a predetermined key, for example, a channel down key in the first function key 12 in the determination of S425, the memory address of one step is reduced from the current memory address and all stored in the corresponding memory address. The control frequency code for the controlled device of the brand is sequentially transmitted (S426).

In the determination of S425, if it is not an input of any designated, for example, channel down key signal for performing memory address reduction, it is determined whether it is a signal of any designated key, for example, a volume up key in the first function key 12. (S427).

If it is detected by the input of any key specified in the determination of S427, for example, the volume up key in the first function key 12, control is performed on the controllers of all brands stored in the corresponding memory area from the current memory address. The frequency code is sequentially transmitted (S428).

If it is determined in the determination in S427 that it is not the input of any of the designated keys, for example, the volume up key in the first function key 12, the specified arbitrary key provided in the second function key 13, for example, the shift It is determined whether the key is input (S429).

If it is determined that the input of any key, for example, a shift key, specified in S427, the control frequency code is transmitted again from the first address of the corresponding controlled device of the brand stored in the current memory address, and then another key is input. Branches to a routine for determining whether or not (S430).

For example, when the current brand starts with 'A' and the controlled device is 'VCR', the controller 20 controls the 'VCR' from the first address of the 'VCR' memory, which is the current controlled device. The frequency code is sent out.

In addition, if it is determined in the determination of S429 that it is not an input of a specified key, for example, a shift key, it is determined whether an input of a specified key, for example, a mute key in the first function key 12, is input. (S431).

If it is determined in step S431 that a predetermined key, for example, a MUTE key in the first function key 12 is input, a predetermined control frequency code for a controller of the current brand stored in the current memory address Send (S432).

At this time, if the target device to be reacted by the input of the predetermined key, for example, the MUTE key in the first function key 12, enters the next step, otherwise enters the key again. It is judged whether or not it is an input of a predetermined key, for example, a setting key in the first function key 12 (S433).

If it is determined that the input of any key, for example, the setting key in the first function key 12 in step S433, the control frequency code for the current brand and the corresponding controlled device is set to the control frequency code currently transmitted. (S434).

By repeating the above process, the control mode code setting mode for all controlled devices of all brands is performed.

In addition, if any number key of 1 to 9 in the second function key 13 is selected for a predetermined time in step S420 and the frequency setting mode for each brand is set, the brand selected by the routine shown in FIGS. 5A to 5B is attached. A control frequency setting is performed for any controlled device, which is executed as follows.

In operation S501, it is determined whether an arbitrary setting key input for designating entry of a code setting mode for each brand is detected among all keys implemented on the remote controller pad in the state of scanning the key input.

When an input of a setting key is detected in S501, in a state of entering a code setting mode for each brand (S502), a key input is scanned to determine whether any key signal input is detected within a predetermined time period, preferably within 3 seconds. (S503) (S504).

If any key signal input is not detected within the predetermined time in the above determination, the setting mode of the control frequency code for the controller for each brand is terminated. If any key signal input is detected within the predetermined time, the current brand is selected. The key, for example, determines whether the number key 1 for selecting the 'ABC' brand is pressed once (S505).

If it is determined in S505 that the current brand selection key, for example, the number key 1 for selecting the 'ABC' brand is pressed once, all controllers for each brand stored in the memory area corresponding to the number key 1 The control frequency code is transmitted sequentially (S506).

That is, the control frequency code for the controlled devices of all brands having the brand initials of 'A', 'B', and 'C' assigned to the numeric key 1 is transmitted.

If it is determined in S505 that the current brand selection key, for example, the number key 1 for selecting the 'ABC' brand is not pressed once, it is determined whether the number key 1 has been pressed twice (S507).

If it is determined in S507 that the current brand selection key, for example, the number key 1 for selecting the 'ABC' brand is pressed twice, all the brands stored in the memory area corresponding to the number key 1, namely 'A', The control frequency code for all the controllers of the brand starting with the first brand 'A' from the brands 'B' and 'C' are transmitted (S508).

In addition, if it is determined in S507 that the number key 1 for selecting the current brand selection key, for example, the 'ABC' brand is not pressed twice, it is determined whether the number key 1 has been pressed 3 times (S509).

If it is determined in S509 that the current brand selection key, for example, the number key 1 for selecting the 'ABC' brand has been pressed three times, all brands stored in the memory area corresponding to the number key 1, namely 'A', The control frequency code for all the controllers of the brand starting with the second brand 'B' from the brands 'B' and 'C' are transmitted (S510).

In addition, if it is determined in S509 that the current brand selection key, for example, the number key 1 for selecting the 'ABC' brand is not pressed three times, it is determined whether the number key 1 has been pressed four times (S511).

If it is determined in step S511 that the current brand selection key, for example, the number key 1 for selecting the 'ABC' brand is pressed four times, all the brands stored in the memory area corresponding to the number key 1, namely 'A', The control frequency code for all the controllers of the brand starting with the third brand 'C' from the brands 'B' and 'C' are transmitted (S512).

In the example of the above description, the numeric key 1 has been described, but the operation of transmitting the control frequency code of the controlled device through the brand selection of the numeric keys 2 to 9 is performed in the same manner as the above-described operation. Is omitted.

In step S505, S507, S509, and S511, a key input is scanned to determine whether a new key signal is detected in the process of transmitting a control frequency code for each brand according to the number of times the brand selection key is pressed (S521).

When the input of the key signal is detected in the determination of S521, it is determined whether it is a designated key, for example, a channel up key in the first function key 12 (S523).

If it is determined in step S523 that the signal is a channel up key signal, the memory for each transmission mode is increased in the process of transmitting a control frequency code for each brand according to the number of times the current brand selection key is pressed, such as S506, S508, S510, and S512. In step S524, the control frequency code stored in the increased memory is transmitted.

If it is determined in the determination in S523 that the signal is not a signal of the channel up key in the designated key, for example, the first function key 12, the channel is down in the other specified key, for example, the first function key 12. It is determined whether the key is input (S525).

If it is determined in the determination of S525 that it is input of a predetermined key, for example, a channel down key in the first function key 12, according to the number of times the current brand selection key is pressed, such as S506, S508, S510, and S512. In the process of transmitting the control frequency code for each brand, the memory for each transmission mode is reduced and the control frequency code stored in the reduced memory is transmitted (S526).

If it is determined in the determination of S525 that it is not an input of the channel down key in the predetermined key, for example, the first function key 12, the volume in another predetermined key, for example, the first function key 12, is specified. It is determined whether the up key is input (S527).

If it is determined that an arbitrary key designated in S527, for example, the volume up key in the first function key 12, is inputted, the control frequency for each brand according to the number of times the current brand selection key is pressed, such as S506, S508, S510, and S512. In the process of transmitting the code, the control frequency code for each transmission mode is sequentially transmitted (S526).

Subsequently, in response to the input of any key designated in the first function key 12, the control frequency for the currently controlled controller is transmitted in the process of transmitting the control frequency code for the controlled controller, such as S524, S526, and S528. It is determined whether the code is the first starting address of all the brand areas (S529). If it is determined that the starting address is not the starting address, the routine returns to the routine of S521 and repeatedly performs the above-described process. Exit code setup mode.

In addition, if it is determined in the determination in S527 that it is not the selection of any of the designated keys, for example, the volume up key in the first function key 12, the other specified arbitrary key, for example the second function key 12, is determined. It is determined whether the shift key (Shift) is input (S530).

If it is determined that the input of any key, for example, the shift key in the second function key 12 in S530, the control frequency code for the current controlled device is transmitted again from the beginning (S531) and muted (MUTE). If it is determined that the key is input, a frequency code set for the controller of the current brand is transmitted (S533).

As described above, the designated arbitrary key, for example, the first function key 12, which sets the corresponding control frequency code as the controlled device of the corresponding brand responds to the transmission of the set control frequency code for the current controlled device. When the signal of the set key is detected in step S), the control frequency code of the controlled device for the current brand is set (S534) (S535).

The brand category for the alphabet displayed on each numeric key, which is the second function key 12, is set as shown in Table 1 below.

An code (last code) is sequentially output, the B brand codes of group 1 are selected, and then the control frequency codes set for group B, such as group 2, namely B1 code, B2 code. The Bn code (last code) is sequentially output, and the C brand codes of the group 1 are selected, and then the control frequency codes set for the C group, such as the group 2, that is, the C1 code, the C2 code. The data of the Cn code (last code) is sequentially output.

In Table 1 above, for example, pressing the number key 1 marked ABC twice selects the A brand codes of Group 1 from the brand category for the entire ABC from the memory storing the table as shown in Table 1 above. The control frequency code set for group A, namely A1 code, A2 code… An code (last code) is output sequentially.

Similarly, pressing the numeric key 1 labeled ABC three times selects the B brand codes of group 1 from the brand category for the entire ABC from the memory storing the table shown in Table 1 above, and then groups B such as group 2 The control frequency code set for the B1 code, B2 code. The Bn code (last code) is output sequentially.

In addition, if you press the numeric key 1 labeled ABC four times, the C brand codes of Group 1 are selected from the brand category for the entire ABC from the memory storing the table shown in Table 1 above, and then the C group as shown in Group 2 Control frequency code set for C1 code, C2 code. Cn codes (last code) are output sequentially.

In the above description, a designated key for performing a specific function is defined as a channel up key, a channel down key, a volume up key, a shift key, a mute key, a setting key, and the like. It is possible to change the program by using other keys.

In addition, although the setting of the category group for the brand initials has been described, a person skilled in the art can also implement a product setting method through a Hangul input method applied by a mobile communication terminal by changing a simple program. It is included in the scope of the invention.

As described above, the present invention sets a control frequency code for various controlled devices for each of various manufacturers by using the initials of a manufacturer for an arbitrary controlled device, so that if only the brand initial of the controlled device is known, Compared to the code setting method of, control frequency code can be set simply and conveniently.
