[0021] In order to make the above objectives, characteristics and advantages of the present application more obvious and easy to understand, the following preferred embodiments are specifically described below, and the accompanying drawings are referred to for a detailed description.
[0022] At present, in order to reduce the noise and annoyance degree generated when the oil smoke machine runs, in the related art, noise masking is realized by playing specific masking audio under different gears. However, when the oil smoke machine is frequently switched between gears, the phenomenon of audio logic disorder is prone to occur, which makes the user subjectively feel that the audio is chaotic, and thus reduces the user experience.
[0023] Based on this, the control method and device of the oil smoke machine and the oil smoke machine provided by the embodiments of the present application can intelligently manage the switching logic of the audio, ensure that the switching process of the audio runs smoothly and the experience is coherent, and thus improve the user experience In order to facilitate the understanding of the present embodiment, first, a control method of an oil smoke machine disclosed by the embodiments of the present application is described in detail.
[0024] In a possible implementation, the embodiment of the present application provides a control method of a range hood, which is applied to the range hood, and specifically, the range hood in the embodiment of the present application is configured with a loudspeaker assembly, and specifically, as shown in Figure 1 FIG. 1 is a schematic diagram of a range hood, for ease of illustration, Figure 1 FIG. 1 is a front view of the range hood, which includes a main box 101, a smoke collecting cavity 102, and a loudspeaker assembly 103, wherein Figure 1 In the embodiment, the loudspeaker assembly 103 is arranged on the front panel of the smoke collecting cavity 102 and is used to play audio. In actual use, the loudspeaker assembly can be a single loudspeaker or an array of multiple loudspeakers, and the number of loudspeaker assemblies can be one or multiple, which can be set according to actual use, and the embodiment of the present application does not limit this.
[0025] Further, Figure 2 FIG. 2 is a flowchart of a control method of a range hood, and the method includes the following steps. Step S202, in response to a gear switching operation acting on the range hood, determining whether a switching time corresponding to the gear switching operation is located within a preconfigured cooling period; In the embodiment of the present application, the cooling period is generated at the previous gear switching operation. Step S204, if yes, switching the running gear of the range hood to a target gear corresponding to the gear switching operation; Step S206, monitoring the duration of the cooling period, and if it is monitored that the duration of the cooling period reaches a preset duration threshold, controlling the loudspeaker assembly of the range hood to play gear audio corresponding to the target gear; The gear audio is used to perform noise masking on the range hood at the target gear.
[0026] In actual use, the above gear switching operation can also be used as audio switching operation. Specifically, the inherent noise of different gears is different when the range hood is running, and therefore, corresponding audio can be preconfigured for different running gears. For example, the first audio corresponds to the low gear, the first audio at this time is mostly soft and natural sound, the second audio corresponds to the medium gear, the second audio is mostly stable flowing sound, and the third audio corresponds to the high gear, and the third audio is usually white noise type audio. When the range hood switches gears, the corresponding audio is also switched synchronously. In the embodiment of the present application, the switching time t nand set a cooling period for each gear switching operation, that is, after the current gear switching operation is completed, start timing, if the gear switching operation is repeated before the duration of the cooling period reaches the duration threshold, the range hood switches the gear, and the audio is not switched at the same time, but is switched to the gear audio after the cooling period ends to perform noise masking on the range hood at the target gear.
[0027] For example, let Tc represent the duration threshold of the cooling period, and the switching time of the previous gear switching operation is tn-1. If that is, if a new gear switching operation is detected within the duration threshold of the cooling period, the gear switching operation does not immediately trigger the audio switching, but after the gear switching is run to the target gear corresponding to the gear switching operation, the duration of the cooling period is continuously monitored until the duration of the cooling period reaches the preset duration threshold, and then the speaker assembly of the range hood is controlled to play the gear audio corresponding to the target gear.
[0028] Further, if multiple gear switching operations are monitored within the above-mentioned cooling period, the gear corresponding to the last gear switching operation is determined as the target gear of the range hood. When the duration of the cooling period reaches the preset duration threshold, that is, after the cooling period ends, the speaker assembly of the range hood is controlled to play the gear audio of the target gear corresponding to the last gear switching operation.
[0029] Further, if it is determined in the above-mentioned step S202 that the switching time corresponding to the gear switching operation is not located within the preconfigured cooling period, that is, the running gear of the range hood is switched to the target gear corresponding to the gear switching operation, and the speaker assembly of the range hood is controlled to play the gear audio corresponding to the target gear; and at this time, the timing function corresponding to the cooling period needs to be started, that is, the duration of the cooling period is recorded again until the duration of the cooling period reaches the preset duration threshold. If the gear switching operation is not monitored again within the cooling period, the cooling period ends, and if the gear switching operation is monitored again one or more times within the cooling period, each gear switching operation can trigger the cooling period to record the duration again, or continue to monitor the duration based on the duration of the original cooling period instead of recording it again. The actual use can be used as a reference, and the embodiments of the present application do not limit this.
[0030] The duration threshold Tc of the above-mentioned cooling period is usually set to Tc≤3s, and can be adaptively adjusted according to the operation frequency of the user. In addition, if the above-mentioned gear switching operation is the first gear switching operation after the range hood is turned on, the running gear of the range hood is normally controlled to switch to the target gear corresponding to the gear switching operation, and the speaker assembly of the range hood is controlled to play the gear audio corresponding to the target gear.
[0031] Further, in order to realize the adaptive adjustment of the length threshold of the cooling period, in the embodiment of the application, the use record of the range hood can be obtained periodically; the number of operations in a preset time period is extracted from the use record; and the length threshold of the cooling period is adjusted based on the number of operations.
[0032] For example, the big data analysis record can be used to extract the operation record of each short time, and the length threshold of the cooling period is adjusted according to the number of short-time operations N, which is specifically expressed by the following formula: ; wherein, is the basic cooling time, is an adjustment coefficient for suppressing frequent false touch behavior.
[0033] The specific adaptive adjustment time interval can be set according to the actual use, and in addition, the user can manually set the length threshold Tc of the cooling period according to the actual use demand, and the actual use is used as the criterion, and the embodiment of the application does not limit this.
[0034] Further, in order to realize the smooth switching of the audio, in the step S206, when the loudspeaker assembly of the range hood is controlled to play the gear audio corresponding to the target gear, the fading mode of the gear audio corresponding to the target gear can be determined; and then the loudspeaker assembly of the range hood is controlled to play the gear audio according to the fading mode.
[0035] The fading mode can be a mixed playing mode based on the cross-fading of the old audio and the new audio. Specifically, the first amplitude information of the gear audio corresponding to the target gear and the second amplitude information of the gear audio currently played by the range hood can be extracted; the transition audio corresponding to the fading mode is determined based on the first amplitude information and the second amplitude information; when the loudspeaker assembly of the range hood is controlled to play the gear audio, the loudspeaker assembly of the range hood can be controlled to play the transition audio corresponding to the fading mode, and after the transition audio is played, the loudspeaker assembly of the range hood is controlled to play the gear audio.
[0036] Specifically, the determination formula of the transition audio can be expressed as:
[0037] wherein, is the second amplitude information, also referred to as the sampling amplitude sequence of the old gear audio, is the first amplitude information, also referred to as the sampling amplitude sequence of the new gear audio, is the amplitude information of the transition audio, also referred to as the sampling amplitude sequence of the transition audio. is a transition function that is smoothly increased from 0 to 1, and the duration thereof can be configured to be about 0.8-1.2 seconds.
[0038] Based on the above transition audio, when the speaker assembly of the range hood plays the transition audio, for the previous gear audio, a transition playback mode of gradually reducing the volume and gradually increasing the volume of the gear audio corresponding to the new target gear can be presented, the smooth transition of the gear audio is realized, and the high-end feeling of the range hood and the comfort of the user are improved.
[0039] Further, in the embodiment of the present application, a buffer audio can also be set, that is, if the user switches the gear of the range hood during the cooling period, the buffer audio can be played, and after the cooling period ends, it directly transitions to the final gear audio. Specifically, if it is judged that the switching time corresponding to the gear switching operation is located in the pre-configured cooling period, the pre-configured buffer audio is obtained; the speaker assembly of the range hood is controlled to play the buffer audio; in response to the duration of the cooling period reaching a preset duration threshold, the speaker assembly of the range hood is controlled to play the gear audio corresponding to the target gear.
[0040] In actual use, the above-mentioned buffer audio can be set according to the gear of the range hood, specifically, the last running gear and the target gear of the range hood can be obtained; the buffer gear is determined based on the last running gear and the target gear; and the buffer audio corresponding to the buffer gear is searched in the pre-configured audio database.
[0041] Specifically, the above-mentioned buffer gear can be an intermediate gear between the last running gear and the target gear, which is usually a virtual gear, or the buffer gear is determined as the gear difference between the last running gear and the target gear, and the corresponding buffer audio corresponds to the buffer gear, for example, different buffer audios can be set for different buffer gears, and a buffer audio of an intermediate frequency can be set according to the frequency of the range hood corresponding to the last running gear and the target gear; in addition, a neutral buffer sound can also be directly set as a buffer audio, which is played after the gear switching operation is monitored during the cooling period, and then directly transitions to the final gear audio after the cooling period ends.
[0042] In summary, the control method of the range hood provided by the embodiment of the present application can ensure the response speed of the gear audio injection function and ensure that the gear audio remains stable and natural, not only improving the high-end feeling of the range hood, but also helping to improve the comfort of the user.
[0043] Further, the embodiment of the present application also provides a control device of a range hood, and the range hood is provided with a speaker assembly, as shown in Figure 3 The device includes the following steps: The judgment module 30 is configured to determine whether the switching time corresponding to the gear switching operation is located in the cooling period in response to the gear switching operation of the range hood. The switching module 32 is configured to switch the running gear of the range hood to the target gear corresponding to the gear switching operation if the determination result of the judgment module is yes. The playing module 34 is configured to monitor the duration of the cooling period, and control the loudspeaker assembly of the range hood to play the gear audio corresponding to the target gear if the duration of the cooling period reaches the preset duration threshold.
[0044] Further, the device is further configured to determine the gear corresponding to the last gear switching operation as the target gear of the range hood if multiple gear switching operations are monitored in the cooling period.
[0045] Further, the device is further configured to switch the running gear of the range hood to the target gear corresponding to the gear switching operation, and control the loudspeaker assembly of the range hood to play the gear audio corresponding to the target gear if it is determined that the switching time corresponding to the gear switching operation is not located in the cooling period, and start the timing function corresponding to the cooling period and record the duration of the cooling period until the duration of the cooling period reaches the preset duration threshold.
[0046] Further, the device is further configured to obtain the use record of the range hood, extract the number of operations in a preset time period from the use record, and adjust the duration threshold of the cooling period based on the number of operations.
[0047] Further, in the playing module, the step of controlling the loudspeaker assembly of the range hood to play the gear audio corresponding to the target gear includes determining the fade-out mode of the gear audio corresponding to the target gear, and controlling the loudspeaker assembly of the range hood to play the gear audio in the fade-out mode.
[0048] The step of determining the fade-out mode of the gear audio corresponding to the target gear includes extracting the first amplitude information of the gear audio corresponding to the target gear and the second amplitude information of the gear audio currently played by the range hood, and determining the transition audio corresponding to the fade-out mode based on the first amplitude information and the second amplitude information. The step of controlling the loudspeaker assembly of the range hood to play the gear audio in the fade-out mode includes controlling the loudspeaker assembly of the range hood to play the transition audio corresponding to the fade-out mode, and controlling the loudspeaker assembly of the range hood to play the gear audio after the playing of the transition audio is completed.
[0049] Furthermore, the aforementioned device is also used to: if it is determined that the switching time corresponding to the gear switching operation is within a pre-configured cooling period, then acquire a pre-configured buffer audio; control the speaker assembly of the range hood to play the buffer audio; and respond to the cooling period duration reaching a preset duration threshold, control the speaker assembly of the range hood to play the gear audio corresponding to the target gear.
[0050] The step of controlling the speaker assembly of the range hood to play buffered audio includes: obtaining the previous operating level and target level of the range hood; determining the buffer level based on the previous operating level and target level; and searching for the buffered audio corresponding to the buffer level in a pre-configured audio database.
