Since the wireless control signal is radiated to the space through the antenna in the form of electromagnetic waves. In order to achieve a high radiation efficiency, the size of the antenna should generally be larger than a quarter of the wavelength of the transmitted signal. The converted wireless control signal contains a longer wavelength of a lower frequency component, so that the antenna is too long to be realized. The frequency spectrum of the wireless control signal is moved to a higher carrier frequency through modulation, so that the size of the radiating antenna can be greatly reduced. In addition, the modulation can respectively move a plurality of wireless control signals to different carrier frequencies so as to realize the multiplexing of channels and improve the utilization rate of the channels.

The signal conversion module 15 receives and analyzes the modulated wireless signal to generate a control signal, and transmits the control signal to the electrical appliance to control the electrical appliance. If the ratio of the target voice feature obtained from the feature extraction unit 142 to the preset voice feature in the storage module 16 is smaller than the voice feature matching threshold set in the threshold setting unit 141, the matching analysis unit 143 sends an infrared conversion negative feedback signal to the mesh networking module 19, or does not send a feedback signal to the mesh networking module 19, that is, the signal conversion module 15 does not send a control signal.
For example, assuming that the preset voice feature in the storage module 16 is a related voice feature of an instruction sentence "please open a fan" of the user a, if the first collection module 11 collects related voice data of an instruction sentence such as "open a fan", "please open a fan", or "open a fan" of the user a or the user B, the preprocessing module 13 performs an impurity removal preprocessing on the voice data of the instruction sentence of the user a or the user B to obtain target voice data of the instruction sentence, the feature extraction unit 142 of the voice recognition module 14 performs voice feature extraction on the target sentence data, the matching analysis unit 143 compares the related target voice feature of the instruction sentence such as "open a fan", "please open a fan", or "open a fan" of the user B obtained from the feature extraction unit 142 with the preset voice feature of the instruction sentence "please open a fan" in the storage module 16, if the comparison ratio is greater than or equal to the voice feature matching threshold set in the threshold setting unit 141, if the threshold is 90%, that is, if the ratio of the relevant target voice feature of the instruction sentence such as "turn on fan", "please turn on fan", or "turn on fan" of the user a obtained in the feature extraction unit 142 to the preset voice feature of the instruction sentence "please turn on fan" of the user a in the storage module 16 is greater than or equal to 90%, it is considered that the matching is successful, the matching analysis unit 143 generates a positive feedback signal and transmits the positive feedback signal to the signal modulation module 12 through the mesh networking module 19, the signal modulation module 12 modulates the positive feedback signal and generates a modulated wireless signal, the signal conversion module 15 receives and analyzes the modulated wireless signal, generates a corresponding control signal, and controls the fan to be turned on through the control signal. Otherwise, the matching analysis unit 143 generates a signal conversion negative feedback signal to the signal conversion module 15, or does not generate a signal conversion feedback signal to the signal conversion module 15, that is, the signal conversion module 15 does not operate.
