[0030] In the first embodiment, referring to FIG. 1, a sound-controlled gas control system for adjusting the height change of the generated flame includes an audio module 1, a transformation analysis module 2, a driving module 3, at least one proportional valve 4, and an audio amplifier 5.

[0031] The audio module 1 is adapted to receive a digital audio signal and generate audio data according to the digital audio signal, and then to preprocess the discrete audio data and generate complex-number data according to the result of the preprocessing. The transformation analysis module 2 is adapted to perform a Fourier transformation on the complex-number data to generate a plurality of frequency domain data and perform spectrum analysis on the frequency domain data to generate pulse width modulation data. The driving module 3 is suitable for receiving the pulse width modulation data and converting to an opening control signal according to the pulse width modulation data. The opening control signal includes, but is not limited to, a current or voltage signal. The proportional valve 4 has a gas valve, and the proportional valve 4 is suitable for adjusting the opening and closing state of the gas valve according to the opening control signal, and the opening and closing state includes an opening and closing ratio and an opening and closing speed.

[0032] Specifically, the collection method for the audio data includes, but is not limited to, a Bluetooth connection terminal, such as a mobile phone, tablet, computer, smart speaker, etc. It should be noted that the digital signal transmission is used between the Bluetooth connection terminal and the audio module 1, which makes the processing fast and the distortion low. In addition, compared with the connection of a wire or wireless network, the Bluetooth connection method can achieve short-distance communication, and has low cost and low power consumption.

[0033] The preprocessing includes following steps: performing a framing process on the audio data to generate the nth frame data; performing a windowing process on the nth frame data if n is not equal to the last frame; and performing a zero-padding operation on the last frame data and then perform the windowing process on the last frame data if n is equal to the last frame. The windowing process can effectively reduce spectrum leakage.

[0034] The spectrum analysis includes following steps: extracting an amplitude value and a phase value of at least one specific frequency segment in the frequency domain data and generating control information according to the amplitude value and the phase value; and generating the pulse width modulation data according to the control information and by using a timer.

[0035] It should be noted that the above specific frequency segment is below 150 Hz, which is recorded as a low-frequency segment. For example, the low-frequency segment, below 150 Hz, combined with actual usage, plays a supporting role in the music structure, can express the low-frequency content of the music, make the audience feel a weak and effective dynamic feeling, and make people's senses resonate with the music and the flames.

[0036] In addition, the setting of the frequency segment can be partially based on the frequency range of interest selected by human needs.

[0037] The interface of the proportional valve 4 in the gas system is connected to the gas storage tank by a pipeline, and the pipeline adopts a hose or a metal pipe. The proportional valve 4 is a device for controlling the mixing ratio of gas and air. The proportional valve 4 changes the mixing ratio of the gas and the air by controlling the opening degree of the proportional valve 4.

[0038] Secondly, the opening and closing ratio and opening and closing speed of the proportional valve 4 are controlled by the amplitude change and frequency change of the audio data in the selected frequency segment, so as to achieve the changing effect of the height and speed of the flame. A specific frequency segment corresponds to a proportional valve 4, so that the control signal of each frequency segment is output to control a proportional valve 4. The number of the specific frequency segments can be set to multiple, and the number of the corresponding proportional valves 4 is also set to multiple. By setting multiple the specific frequency segments and multiple the proportional valves 4, a richer flame effect can be achieved.

[0039] The opening speed and closing speed are set to every x seconds. Every x seconds, the proportional valve 4 adjusts the corresponding opening and closing ratio once according to the real-time audio data received, and also the Fourier transformation is performed once every x seconds.

[0040] A plurality of specific frequency segments are extracted from the frequency domain data in equal width division or equal proportion division. It is preferred to use the equal proportion division, such as 0-16 Hz, 16-32 Hz, 32-64 Hz, and so on, which means that the frequency segment width of the low frequency segment is narrower, while the frequency segment width of the high frequency segment is wider. This method is more suitable for audio and sound analysis because it is closer to the human ear's perception of frequency. Correspondingly, each flame will change and jump in each frequency segment.

[0041] Refer to FIG. 7, which is the software interface of the sound-controlled gas system. The horizontal axis of FIG. 7 is frequency, and the vertical axis of FIG. 7 is amplitude. There are 11 specific frequency segments, respectively corresponding to 11 proportional valves 4. It is set to obtain the corresponding amplitude data in the specific frequency segments every 1 second. For example, FIG. 7 shows the amplitude values corresponding to multiple specific frequency segments at the 32nd second. According to the amplitude value, the opening and closing ratio of the corresponding proportional valve 4 is adjusted. When the amplitude value is large, the opening and closing ratio of the proportional valve 4 is large, and the flame becomes high, and when the amplitude value is small, the opening and closing ratio of proportional valve 4 is small, and the flame becomes low, forming the effect of different heights of the flame.

[0042] The setting of x seconds can be determined according to the rhythm of the music. When the rhythm is fast, the value of x is small, and the flame will become faster following the replacement frequency of the proportional valve 4; when the rhythm is slow, the value of x is large, and the flame will become slower following the replacement frequency of the proportional valve 4. Therefore, when the music switches, the system will adjust the corresponding opening and closing speed in real time according to the rhythm of the music.

[0043] The transformation analysis module 2 controls the opening and closing states of the gas valves of different proportional valves 4 according to the pulse width modulation data respectively corresponding to the specific frequency segments.

[0044] The above audio amplifier 5 is suitable for playing music according to a digital audio signal, wherein the rhythm of the music changes in sync with the height of the flame.

[0045] In the second embodiment, referring to FIG. 2, a sound-controlled gas control method includes the following steps: [0046] S1: preprocessing discrete audio data and generating complex-number data according to the result of the preprocessing; [0047] S2: performing Fourier transformation according to the complex-number data to generate a plurality of frequency domain data; [0048] S3: performing spectrum analysis on the frequency domain data to generate pulse width modulation data, and converting to an opening control signal according to the pulse width modulation data; and [0049] S4: adjusting an opening and closing state of a gas valve of a proportional valve according to the opening control signal.

[0050] Furthermore, the preprocessing in S1 includes the following steps: [0051] S11: performing a framing procedure on the audio data to generate nth frame data; and [0052] S12: performing a windowing process on the nth frame data if n is not equal to the last frame, and performing a zero-padding operation on the last frame data and then performing the windowing process on the last frame data if n is equal to the last frame.

[0053] Furthermore, the spectrum analysis in S3 includes the following steps: [0054] S31: extracting an amplitude value and a phase value of at least one specific frequency segment in the frequency domain data, and generating control information according to the amplitude value and the phase value; and [0055] S32: generating the pulse width modulation data according to the control information and by using a timer.

[0056] In the third embodiment, referring to FIG. 5, a sound-controlled gas control device is used as a carrier for executing the above-mentioned sound-controlled gas control system, specifically, including a power switch 6, an on-chip system 7, a drive circuit 8, and a start-stop switch 9.

[0057] The audio module 1 and the transformation analysis module 2 are both electrically connected to the on-chip system 7, and the driving module 3 includes the drive circuit 8.

[0058] The power switch 6 is electrically connected to the audio amplifier 5, the on-chip system 7, and the drive circuit 8, and serves as a power supply. The solid line in the figure indicates the electrical connection relationship.

[0059] The start-stop switch 9 is electrically connected to the on-chip system 7 for starting and stopping the rhythmic function of the flame. The on-chip system 7 is used to receive the digital audio signal and generate the audio data according to the digital audio signal, and then to preprocess the discrete audio data and generate the complex-number data according to the result of the preprocessing. Then, the transformation analysis module 2 is used to perform Fourier transformation according to the complex-number data to generate a plurality of frequency domain data and perform the spectrum analysis on the frequency domain data to generate the pulse width modulation data.

[0060] The output terminals of the on-chip system 7 are respectively electrically connected to the audio amplifier 5 and the drive circuit 8. The output terminal of the on-chip system 7 is electrically connected to the drive circuit 8. The drive circuit 8 is used to receive the pulse width modulation data and convert to an opening control signal according to the pulse width modulation data. The drive circuit 8 is electrically connected to the proportional valve 4. The proportional valve 4 is used to adjust the opening and closing state of the gas valve according to the opening control signal. The audio amplifier 5 is used to play music according to the digital audio signal, and the rhythm change of the music is synchronized with the height change of the flame. The dashed lines in the figures represent the signal connection relationships.

[0061] In the fourth embodiment, referring to FIG. 6, a microcontroller unit 10 is added, which is different from the setting of the sound-controlled gas control device in the third embodiment. The microcontroller unit 10 is an external component and has a computing function. Moreover, the audio module 1 includes the on-chip system 7, and the transformation analysis module 2 includes the microcontroller unit 10.

[0062] The on-chip system 7 in this embodiment is used to receive the digital audio signal and generate the audio data according to the digital audio signal, and then to preprocess the discrete audio data and generate the complex-number data according to the result of the preprocessing. The microcontroller unit 10 is adapted to perform the Fourier transformation on the complex-number data to generate the plurality of frequency domain data and perform the spectrum analysis on the frequency domain data to generate the pulse width modulation data.

[0063] In the case where the on-chip system 7 cannot directly control the proportional valve 4, the operation method is as follows: the power switch 6 is electrically connected to the microcontroller unit 10, the on-chip system 7 is electrically connected to the driving module 3 through the microcontroller unit 10 for signal communication, and the microcontroller unit 10 controls the proportional valve 4 through the drive circuit 8, thereby ensuring the realization of the sound-controlled gas effect.
