Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, in order that those skilled in the art can easily carry out the present invention. In the following detailed description of the preferred embodiments of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. In the drawings, like reference numerals are used throughout the drawings.

In addition, in the entire specification, when a part is referred to as being 'connected' to another part, it may be referred to as 'indirectly connected' not only with 'directly connected' . Also, to "include" an element means that it may include other elements, rather than excluding other elements, unless specifically stated otherwise.

1 and 2 are schematic views showing a sound wave communication apparatus according to an embodiment of the present invention.

1 and 2, a sound wave communication apparatus according to an embodiment of the present invention may include a microphone unit 10 and a signal analyzer unit 20.

Hereinafter, a sound wave communication apparatus according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG.

The microphone unit 10 can receive a sound wave signal generated by the product 200. The microphone unit 10 can sense the vibration of the sound wave signal inputted from the outside and convert the vibration of the sound wave signal into an electrical signal and transmit the electrical signal to the signal analyzer 20. The microphone unit 10 may be any microphone that senses an acoustic signal and converts the acoustic signal into the electrical signal. In general, a microphone may be used.

2, the air cleaner 210, the bidet 220, the air cleaner 210, the bidet 220, and the air cleaner 210 are installed in the product 200. The air cleaner 210, the bidet 220, And a water purifier 230 may be included. Specifically, a buzzer may be included in the product 200, and when the product 200 has an error or a failure, the buzzer may generate a warning sound to inform the user. However, the buzzer may generate different warning sounds depending on the type of malfunction or the like occurring in the product 200, and it is also possible to include specific information in the alarm sound through frequency modulation. The product 200 may generate the warning sound by using various means other than the buzzer, and may use any sound source capable of generating sounds having different frequencies according to an input control signal.

The signal analyzing unit 20 may analyze the sound wave signal and extract internal information of the product 200 included in the sound wave signal. 3, the signal analyzer 20 may generate an input signal sig_IN corresponding to the frequency modulation of the sound wave signal sig_aco, and may use the input signal sig_IN So that the internal information can be extracted.

Specifically, as shown in FIG. 3A and FIG. 3B, when the warning sound is implemented by two kinds of frequencies, binary data corresponding to the frequency type is input to the input signal sig_IN, . In the case of Fig. 3 (a), the frequency of 0 KHz corresponds to "0" and the frequency of 4 KHz corresponds to "1". Therefore, the input signal sig_IN corresponding to the input sound signal sig_aco can be converted to "010110100" as shown in the figure. In the case of FIG. 3 (b), the frequency of 1 KHz corresponds to "0" and the frequency of 4 KHz corresponds to "1", so that the sound signal sig_aco shown in FIG. It can be converted into an input signal sig_IN of "010110100 ".

Further, as shown in FIG. 3 (c), natural numbers from 0 to 9 can be set to correspond to the respective frequency values, and then converted into respective natural numbers corresponding to the frequencies of the input sound signal sig_aco Thereby generating the input signal. In this case, the input signal corresponds to decimal data. For example, 1 can be set to 1 KHz, 2 to 2 KHz, 3 to 3 KHz and 4 to 4 KHz. As shown in FIG. 3 (c), when decimal data is used, a large amount of data can be simultaneously transmitted, so that the communication speed can be improved as compared with the method of transmitting the binary data.

However, even if the sound signal sig_aco is converted into the input signal sig_IN, in order to extract the internal information from the input signal, it is necessary to interpret the input signal according to a predetermined communication protocol, 200 also need to generate the sound wave signal according to a predetermined communication protocol.

According to the communication protocol, the sound wave signal includes a start code indicating a start point of the sound wave signal, a size of internal information included in the sound wave signal, an error check code for determining an error of the sound wave signal, and an end point of the sound wave signal And may include an exit code for display. In addition, information on the product 200 that outputs the sound wave signal, information on hardware and software versions of the product 200, and the like may be further included. For example, the sound wave signal may be repeatedly output at the same time with the same signal, and the signal analyzing unit 20 may analyze the sound wave signal and start the analysis of the sound wave signal when the start code is inputted . Since the start code, the type of the product, the software version, the size of the internal information, the internal information, the type code, and the like can be sequentially input according to the order of the communication protocol, The internal information can be easily extracted using a communication protocol.

The internal information may include information on the state of the product 200, and information on a failure or abnormality of the product 200, a location of the failure or an abnormality may be included in the internal information. For example, when it is determined that the filter unit of the water purifier 230 should be replaced, the water purifier 230 may generate a warning sound having a specific combination of frequencies. In this case, the sound wave communication device can derive internal information that the filter unit needs to be replaced from the warning sound, and can provide information to the user that the filter unit of the water purifier 230 should be replaced. In particular, when the water purifier 230 does not include a separate display device, communication through the sound wave signal may be effective. In addition, when an overvoltage is applied to a hot water heater provided in the water purifier 230, the corresponding sound wave signal can be output. The user can derive internal information from the sound wave signal, It can be confirmed that there is a problem of the hot water heater.

Although not shown, the sound wave communication device 100 may further include a product sensing unit. The product sensing unit can acquire information on the product 200 by recognizing a bar code, a quick response (QR) code, and the like attached to the product 200. It is necessary to acquire information on the product 200 in order to accurately communicate with the product 200 since the communication protocol and the frequency modulation method of the sound wave signal output for each product 200 may be different. Accordingly, after the information on the product 200 is obtained through the product sensing unit, the signal analyzing unit 20 is controlled to extract the internal information according to the communication protocol or the frequency modulation method corresponding to the product 200 can do.

Here, the information on the communication protocol and the frequency modulation method may be included in the bar code, the QR code itself, or stored in the acoustic communication device. Alternatively, information on the communication protocol or the frequency modulation method may be stored in an external server. In this case, information on the communication protocol or the frequency modulation method corresponding to the product may be transmitted through the communication between the external server and the sound wave communication device It can be received.

In addition, the acoustic communication device 100 may further include a communication unit. The sound wave communication apparatus 100 may extract the internal information and then transmit the internal information to the external server through the communication unit. Here, the external server may derive status information of the product corresponding to the internal information, and may provide the status information to the sound communication apparatus 100. [ That is, the sound wave communication device 100 extracts the internal information, but the sound wave communication device 100 may not include information on the status of each product 200 corresponding to the internal information. Therefore, information on the specific state of the product 200 can be supplemented through communication with an external server.

Further, the sound wave communication apparatus 100 may further include a display unit (not shown) to display the state of the product 200 corresponding to the state information and provide the state to the user. As shown in Fig. 4 (a), when the sound wave communication device 100 analyzes the sound wave signal to derive internal information, it can notify the user that the sound wave communication device 100 is "fault diagnosis ". 4 (b), when the state information on the state of the product 200 is derived through the internal information, the product 200 is transferred to the product 200 as shown in FIG. 4 (b) So that the user can be notified of the status.

In addition, the sound wave communication device 100 may further include a speaker unit (not shown), and it is also possible to perform bidirectional sound wave communication, half-duplex communication, and the like with respect to the product 200 further including a microphone.

The sound wave communication apparatus 100 may be a mobile communication terminal, a smart phone, a tablet PC, a netbook, a notebook computer, a PDA, or the like, and may be a separately designed product for sound wave communication with the product 200. Particularly, in the case of a smartphone or a tablet PC, it is possible to execute a separate application to perform the sound wave communication. In this case, when it is determined that a malfunction has occurred in the product 200 through the sound wave communication, a fault repair request or the like to the product 200 can be performed using wireless communication of the mobile communication terminal or the like have.

5 is a flowchart showing a sound wave communication method according to an embodiment of the present invention.

5, a sound wave communication method according to an exemplary embodiment of the present invention may include a product sensing step S10, a sound wave signal input step S20, a signal analysis step S30, and a communication step S40 .

Hereinafter, a sound wave communication method according to an embodiment of the present invention will be described with reference to FIG.

In the product detection step (S10), information on the product can be acquired by recognizing a bar code, a QR code, and the like attached to the product. Since the communication protocol or the frequency modulation method of the sound wave signal output for each product may be different, it is necessary to acquire information about the product in order to perform accurate sound wave communication with the product. Accordingly, after the information on the product is obtained through the product sensing step (S10), the internal information may be extracted according to a communication protocol or a frequency modulation method corresponding to the product. In addition, the product sensing step S10 may acquire information on the product through NFC (Near Field Communication) communication or the like.

Thereafter, through the sound wave signal input step S20, the sound wave signal generated by the product can be input. When an internal abnormality or a failure occurs in the product, a buzzer or the like is used to generate a warning sound, so that the warning sound can be received as the sound wave signal.

The signal analysis step S30 may detect the frequency modulation of the sound wave signal, generate an input signal corresponding to the frequency modulation, and extract the internal information of the product using the input signal. As previously mentioned, when a note of a predetermined frequency is input, it can be converted into a corresponding input signal. That is, in the case of a sound wave signal using two frequencies, an input signal composed of binary data can be generated. Thereafter, the input signal may be analyzed according to a predetermined communication protocol to extract internal information included in the input signal. Since detailed description of the signal analysis has been described above, a detailed description thereof will be omitted.

The communication step S40 may transmit the internal information to the external server using wireless communication and receive the status information of the product corresponding to the internal information from the external server. Even when the internal information is extracted from the sound signal through the signal analyzing step S30, it may be difficult to determine what kind of failure or abnormality has occurred in the product using only the internal information. For example, since the internal information extracted from the sound wave signal corresponds to the binary data composed of 0 and 1, if there is no information on the specific product state corresponding to the binary data, the internal information alone can not grasp the state of the product I can not. Therefore, detailed information on an anomaly or failure occurring in the product can be provided through the external server storing the state information of the product corresponding to the internal information.

In addition, upon reception of the status information from the external server, the status of the product corresponding to the status information may be displayed and displayed to the user.

The present invention is not limited to the above-described embodiments and the accompanying drawings. It will be apparent to those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
