The character " / " generally represents that the associated objects before and after are in an "or" relationship.

[0048] 4) "corresponding" can refer to a relationship or binding relationship, A and B corresponding to A and B is a kind of relationship or binding relationship.

[0049] The application scenarios of the embodiments of the present application are explained as follows:

[0050] Figure 1 An application scenario diagram of the water heater control method provided by the embodiments of the present application is shown in FIG. 1. Figure 1 The water heater control method provided by the embodiments of the present application can be applied to the scenario in which a user uses a massage mode of a smart water heater for showering. The execution subject of the method provided by the embodiments of the present application can be the smart water heater, more specifically, a controller, a control chip or other control unit in the smart water heater. On the one hand, the smart water heater is connected to a shower through a pipeline and outputs hot water from the shower through a water delivery pipeline. On the other hand, the smart water heater is in communication connection with a terminal device, for example, a smart speaker. After the smart water heater enters the massage mode based on a control instruction of the user, the smart water heater receives audio data sent by the smart speaker, determines a change rule of the water output in the massage mode through the audio data, and outputs water flow to the shower connected to the smart water heater based on the change rule corresponding to the audio data. Thus, the water output of the shower changes alternately, and a vibrating water flow capable of producing a massage effect on the user's body is output. At the same time, the smart speaker itself plays music according to the audio data sent to the smart water heater, so that the beat of the played music corresponds to the vibration frequency of the vibrating water flow output by the shower, a music-following massage effect is produced, and the user's experience is improved.

[0051] First, the massage mode of the smart water heater in the prior art is introduced.

[0052] The massage mode of the smart water heater is to control the water output of the water heater, so that the speed of the water flow sprayed by the shower connected to the water heater changes alternately. When the water flow with alternating speed falls on the surface of the user's body, the high-speed water flow will produce a greater impact force, and the low-speed water flow will produce a smaller impact force. The vibration produced by the alternating spraying of the high-speed water flow and the low-speed water flow on the surface of the user's body forms an effect similar to patting (i.e., vibrating water flow), thereby realizing the massage effect on the user's body and realizing the "massage mode" of the smart water heater.

[0053] In the related art, in the process of implementing the "massage mode" of the intelligent water heater, one or several fixed gears are usually preset to correspond to the vibration mode of the vibrating water flow sprayed by the shower, for example, the "relaxing" gear, the vibration frequency of the vibrating water flow is low, simulating the "massage" of relaxation; and the "powerful" gear, the vibration frequency of the vibrating water flow is high, to simulate the "massage" of power. It can be seen that in the application scenario of the "massage mode" of the intelligent water heater, if the "pounding" action is to be formed by the water flow to achieve the "massage" effect on the user's body, the vibrating water flow, i.e. the water flow with alternating water quantity, must be used to achieve the difference in "massage" effect, which is mainly realized by the difference in vibration frequency of the vibrating water flow, i.e. the speed of alternating water quantity. The scheme in the related art controls the water outlet of the intelligent water heater based on the fixed and preset vibration frequency, resulting in fixed and single massage gears and poor massage effect.

[0054] Therefore, there is an urgent need for a method to solve the problem of fixed vibration frequency and inability to dynamically change the vibration frequency in the "massage mode" of the intelligent water heater.

[0055] The technical solutions of the present application and how the technical solutions solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0056] Figure 2 The flowchart of the water heater control method provided by an embodiment of the present application is applied to an intelligent water heater, which communicates with a terminal device, as shown in Figure 2 The water heater control method provided by the embodiment includes the following steps:

[0057] Step S101, receiving audio data sent by the terminal device.

[0058] Exemplarily, the terminal device can be a smart terminal, such as a smart phone or a smart speaker, and the terminal device can be connected with the intelligent water heater through wireless communication modes such as wifi and Bluetooth. After the terminal device and the intelligent water heater form a communication connection, the terminal device can send audio data to the terminal device based on the control instruction input by the user. In one possible implementation, the audio data can be an audio file or a streaming media file containing a music segment. The audio data can be used to play the target music after being decoded.

[0059] In another possible implementation, the audio data can be an audio file or a streaming media file representing the beat of the target music, which can be obtained by processing (e.g., filtering, down-sampling) an original audio file including a music segment by the terminal device. Compared with the audio file or the streaming media file including the music segment in the above implementation, the audio data in this implementation cannot be used to play the target music after being decoded, but can represent the beat of the target music and has a smaller size.

[0060] In step S102, water control information is determined according to the audio feature of the audio data, and the water control information is used to represent the change rule of the water output of the intelligent water heater.

[0061] For example, after receiving the audio data, the intelligent water heater stores the audio data locally and obtains the audio feature of the audio data by analyzing the audio data. For example, the audio feature can represent the rhythm change rule of the target music corresponding to the audio data. Specifically, for the target music, different rhythm changes can be included in different stages during the playing process. For example, the rhythm is slow in the prelude part, and the rhythm is fast in the chorus part. The audio feature is a feature representing the rhythm change of the target music. According to the audio feature, the rhythm change rule of the target music can be determined.

[0062] On this basis, in the massage mode of the intelligent water heater, the water output of the water heater also needs to be alternately changed, so as to realize the effect of vibrating water flow. Therefore, based on the rhythm change of the target music corresponding to the audio feature, the change rule of the water output can be determined accordingly. For example, according to the audio feature, in the interval of the fast rhythm of the target music, the corresponding water output is determined to change at a high frequency, so that the vibration frequency of the vibrating water flow sprayed by the shower of the intelligent water heater is also high. In the interval of the slow rhythm of the target music, the corresponding water output is determined to change at a low frequency, so that the vibration frequency of the vibrating water flow sprayed by the shower of the intelligent water heater is also low.

[0063] Specifically, the audio feature of the audio data is implemented by a sequence of feature values, and each feature value in the sequence of feature values is used to represent the playing rhythm (fast or slow) of the target music in the corresponding playing interval. Then, based on a preset proportion coefficient or a sequence of proportion coefficients, the sequence of feature values is weighted to obtain corresponding water control information. For example, the water control information also includes a sequence of values, and each value in the sequence is used to represent the water output change frequency.

[0064] Figure 3 A schematic diagram for determining water control information provided by the embodiment of the present application is shown in FIG. 1. Figure 3As shown, the audio features obtained according to the audio data include a feature value sequence A, which includes three discrete feature values A1, A2 and A3. According to the feature value sequence A and a preset proportion coefficient, the discrete feature values A1, A2 and A3 are weighted respectively to obtain a corresponding water output frequency sequence B and three corresponding discrete points B1, B2 and B3. For example, B1 represents that the water output amount changes at a frequency of 1 Hz, that is, the vibration water flow with a vibration frequency of 1 Hz is output; B2 represents that the water output amount changes at a frequency of 5 Hz, that is, the vibration water flow with a vibration frequency of 5 Hz is output; and B3 represents that the water output amount changes at a frequency of 3 Hz, that is, the vibration water flow with a vibration frequency of 3 Hz is output. A1 and B1 correspond to time stamp a respectively, A2 and B2 correspond to time stamp b respectively, and A3 and B3 correspond to time stamp c respectively. The water output frequency sequence B and the corresponding time stamp sequence (time stamp a, time stamp b and time stamp c) are the water output control information.

[0065] In a possible implementation, before step S103, the method further includes:

[0066] The terminal device sends synchronization information, and the synchronization information is used to represent the current playing progress of the terminal device playing the audio data; the target time stamp is determined according to the synchronization information; and the water output amount of the intelligent water heater is controlled based on the water output amount value corresponding to the target time stamp.

[0067] For example, the synchronization information is the current progress of the terminal device playing the audio data, and more specifically, the synchronization information is, for example, the current playing time stamp of the audio data. For example, the terminal device is a smart speaker, and when the terminal device sends the audio data to the intelligent water heater, the terminal device is playing the audio data. In order to make the intelligent water heater synchronize the progress of playing the audio data with the smart speaker in the process of controlling the water output amount to output the vibration water flow, that is, for example, when the smart speaker plays to the third second of the audio data, the intelligent water heater also uses the water output control corresponding to the water output amount or the water output change frequency of the audio feature at the third second of the audio data to control the water output, so as to realize the "music following massage" function of the intelligent water heater and the smart speaker, make the rhythm of the music played by the smart speaker completely the same as the water flow massage rhythm of the intelligent water heater, and enrich the use experience of the user.

[0068] In step S103, the water output amount of the intelligent water heater is controlled based on the water output control information.

[0069] For example, after the water output control information is determined, the water output amount of the intelligent water heater is controlled based on the change rule of the water output amount represented by the water output control information, so that the intelligent water heater outputs the water flow with the alternately changed water output amount, so that the shower connected with the intelligent water heater can spray the vibration water flow, and the massage effect is realized.

[0070] In a possible implementation, the smart water heater comprises a booster water pump, the booster water pump is configured to control the outlet water pressure of the smart water heater, and the outlet water control information is configured to control the outlet water quantity of the smart water heater, and the outlet water control information comprises:

[0071] The outlet water control information comprises an outlet water quantity sequence, the outlet water quantity sequence comprises a plurality of outlet water quantity values, each outlet water quantity value corresponds to a time stamp, and the change rule of the outlet water quantity can be determined according to each outlet water quantity value in the outlet water quantity sequence and the corresponding time stamp. Then, the outlet water pressure value corresponding to each outlet water quantity value is determined by converting the outlet water quantity value according to a preset water pressure coefficient. The booster water pump is controlled based on the time stamp corresponding to each outlet water quantity value in the outlet water quantity sequence and each outlet water pressure value. More specifically, the booster water pump is sequentially sent instructions according to the time stamp, so that the booster water pump changes the outlet water pressure at the time corresponding to the time stamp, and the outlet water pressure of the booster water pump (that is, the outlet water pressure of the smart water heater) corresponds to the outlet water quantity. It should be noted that the outlet water quantity can be a relative unit, and there is a mapping relationship between the outlet water quantity and the outlet water pressure. However, when the booster water pump discharges water at an outlet water pressure value, the actual outlet water quantity of the smart water heater can be the outlet water quantity corresponding to the outlet water pressure value, or can not be the outlet water quantity. Here, no specific limitation is made.

[0072] Further, since the outlet water quantity sequence corresponding to the outlet water control information is determined by the audio data, the vibration frequency of the vibration water flow sprayed by the shower of the smart water heater corresponds to the rhythm represented by the audio feature of the audio data, thereby realizing the dynamic vibration water flow.

[0073] In this embodiment, the audio data sent by the terminal device is received, the outlet water control information is determined according to the audio feature of the audio data, the outlet water control information is used to represent the change rule of the outlet water quantity of the smart water heater, and the outlet water quantity of the smart water heater is controlled based on the outlet water control information. Since the outlet water control information used to control the outlet water quantity of the smart water heater is determined by the audio data sent by the terminal device, the outlet water control information will change with the change of the audio data, thereby realizing the outlet water quantity change control corresponding to the audio feature of the audio data, and further realizing the dynamic frequency massage of the outlet water flow based on the dynamic change of the outlet water quantity of the water heater, and improving the massage effect and user experience in the massage mode of the water heater.

[0074] Figure 4 The flowchart of the water heater control method provided by another embodiment of the present application is shown in Figure 4 The water heater control method provided by the embodiment is used for Figure 2The water heater control method provided in the embodiment is based on the water heater control method provided in the embodiment shown in the figure, and further refines steps S101-S103 and adds a step of playing timestamp synchronization. The water heater control method provided in the embodiment includes the following steps:

[0075] Step S201, receiving the streaming media data sent by the terminal device.

[0076] Step S202, obtaining an audio segment corresponding to the streaming media data according to the streaming media data.

[0077] Exemplarily, the streaming media data refers to data obtained by segmenting and compressing complete audio data and then sending the segmented data. After receiving the streaming media data sent by the terminal device, the intelligent water heater can obtain a segment of complete target music, i.e., an audio segment corresponding to the streaming media data, by decoding the streaming media data. Related technologies of streaming media transmission, buffering and decoding are prior art known to those skilled in the art, and will not be described here.

[0078] Step S203, determining a beat feature of the audio segment, the beat feature being used to represent the rhythm of the audio segment.

[0079] Exemplarily, after obtaining the audio segment corresponding to the streaming media data, signal processing and feature extraction are performed on the audio segment, and a beat feature used to represent the rhythm of the audio segment can be obtained. Specifically, there are periodic beats in music (for example, the audio segment in the embodiment is a music segment), and the beat is a regular form of organization describing the beats in the music. The beat is a unit for measuring the rhythm, and therefore the rhythm of the music can be determined according to the beat. The beat feature is an informationized representation of different beats, and the beat feature includes, for example, a feature identifier. Feature identifier 1 represents one beat, and feature identifier 2 represents another beat.

[0080] Further, the beat feature of the audio segment can be determined by the audio segment. Specifically, Figure 5 A time-domain waveform diagram of an audio segment provided in an embodiment of the present application is shown in the figure. Figure 5 The time-domain waveform of the audio segment is used to represent the relationship between the sound signal and time, where the vertical coordinate of the waveform curve is the sound energy, and the horizontal coordinate is the time. Exemplarily, referring to the time-domain waveform shown in the figure, Figure 5 The periodic component in the waveform is the beat of the target music corresponding to the audio data. Feature extraction and identification of the periodic component can determine the beat of the target music. Further, based on the interval and combination of different beats, the beat and the corresponding beat feature can be determined.

[0081] Optionally, as shown in the figure, Figure 6As shown, step S203 includes three specific implementation steps S2031, S2032 and S2033.

[0082] Step S2031, obtaining the spectral feature of the audio segment;

[0083] Step S2032, filtering the audio segment based on the spectral feature of the audio segment to obtain filtered audio data;

[0084] Step S2033, extracting the peak value of the filtered audio data to determine the beat feature of the audio segment.

[0085] Specifically, the audio segment is the sound data obtained after decompressing the streaming media data, which can be implemented in the form of an array or a matrix based on different numbers of sound channels. Taking single-channel sound data as an example, Fourier transformation is performed on the sound data to obtain the corresponding spectral data, and then the audio data is filtered according to the spectral feature corresponding to the spectral data, for example, band-pass filtering is performed on the frequency band with the highest energy in the low-frequency interval, thereby obtaining the filtered audio data. The filtered audio data retains the main frequencies in the audio segment, and in the time-domain waveform of the filtered audio data, it is represented as multiple equally spaced peaks. Further, by extracting the peak value of the filtered audio data, the main rhythm rhythm with the highest energy level in the audio segment can be determined. Specifically, for example, it is the sound rhythm emitted by a low-frequency musical instrument, for example, a drum rhythm, i.e., the beat feature.

[0086] In this embodiment, by performing spectral transformation, feature extraction on the audio segment, and filtering based on the spectral graph, the filtering of different beats in the audio segment is realized. The feature of the main beat with the highest energy level is determined as the beat feature, so that the water flow change frequency determined by the intelligent water heater according to the beat feature is synchronized with the main beat of the audio segment, and the user experience is improved.

[0087] Step S204, determining the water flow change frequency according to the beat feature of the audio segment.

[0088] Exemplarily, after determining the beat feature representing the rhythm speed, a frequency value corresponding to the rhythm represented by the beat feature can be determined, i.e., the water flow change frequency. Specifically, the beat feature of the audio segment includes, for example, a beat feature value. Different beat feature values correspond to a water flow change frequency, for example, beat feature value 1 corresponds to a water flow change frequency of 1 Hz, i.e., the water heater changes the water output once per second. Beat feature value 2 corresponds to a water flow change frequency of 2 Hz, i.e., the water heater changes the water output twice per second. Since the water flow change frequency that the water heater can achieve has an upper limit and is related to the performance of the gain water pump provided in the intelligent water heater, the mapping relationship between the beat feature and the water flow change frequency can be set according to specific needs, which is not limited here.

[0089] Step S205, according to the water quantity change frequency, determine the first duration.

[0090] Step S206, get the water quantity sequence, the water quantity sequence includes at least two different water quantity values.

[0091] Exemplarily, after determining the water quantity change frequency, the reciprocal of the water quantity change frequency is the time interval between two water quantity changes, that is, the first duration. The higher the water quantity change frequency, the shorter the first duration, that is, the more frequent the water quantity changes, and the higher the vibration frequency of the output vibrating water flow.

[0092] The water quantity sequence can be a preset data including at least two different water quantity values, for example, a first water quantity value and a second water quantity value, wherein the first water quantity value is greater than the second water quantity value. It should be noted that under the same device conditions (for example, the same model of intelligent water heater and the same model of shower connected to the intelligent water heater), the water quantity and the water pressure of the intelligent water heater are in a positive proportional relationship, that is, the greater the water quantity, the greater the water pressure. The water quantity value in the step of the embodiment is a dimensionless unit, which can represent the water quantity output by the water heater or the water pressure, which is not limited here.

[0093] Since the first water quantity value and the second water quantity value are different in size, the intelligent water heater can generate a vibrating water flow when it alternately outputs water based on the first water quantity value and the second water quantity value in the water quantity sequence. The size of the first water quantity value and the second water quantity value can be set by the user or preset when the device is manufactured, which is not described here.

[0094] Step S207, according to the water quantity sequence and the first duration, control the intelligent water heater to output water with each water quantity value in the water quantity sequence in turn, and the water output time corresponding to each water quantity value lasts the first duration.

[0095] Further, according to the water quantity value in the water quantity sequence and the corresponding first duration, the water quantity control of the intelligent water heater can be realized. Figure 7 A schematic diagram of water quantity control according to the water quantity sequence and the first duration provided by the embodiment of the present application is shown in Figure 7 As shown, the intelligent water heater outputs water with the first water quantity value and the second water quantity value in turn according to the water quantity sequence, and each lasts the first duration until the total duration reaches the playing duration of the audio segment. When the water flow output by the intelligent water heater is delivered to the shower and sprayed by the shower, the effect of vibrating water flow can be realized.

[0096] In addition, it can be understood that the water output sequence can further include other water output values, such as a third water output value, a fourth water output value, and the like. The intelligent water heater controls the water output according to the water output values in the water output sequence. Therefore, the more water output values in the water output sequence, the more complex the change of the water output, and the more vibration modes of the vibration water flow generated finally.

[0097] Figure 8 A process diagram for continuously outputting vibration water flow based on an audio segment is provided for an embodiment of the present application, as shown in the figure, Figure 8 After the intelligent water heater determines the water output control information according to the audio segment a, the water output control is performed in a cycle based on the water output sequence A and the first time length in the water output control information, and the vibration water flow matching the rhythm of the audio segment a is output from the shower connected through the pipeline. Until the total cycle time reaches the playing time of the audio segment a, the intelligent water heater acquires the audio segment b after the audio segment a by loading the streaming media data. After determining the water output control information corresponding to the audio segment b through the same steps, the water output control is performed in a cycle based on the water output sequence B and the second time length in the water output control information corresponding to the audio segment b at the end time point corresponding to the audio segment a, so as to output the vibration water flow matching the rhythm of the audio segment b through the shower. The audio segment a, the audio segment b, and the subsequent audio segment c obtained through the streaming media data represent continuous segments in the target music respectively. When the rhythm of the target music changes, the vibration frequency of the vibration water flow sprayed through the shower will also change accordingly, so as to realize the dynamic massage and the music following massage function of the intelligent water heater, and improve the user experience.
