System and method for controlling electronic equipment

The invention discloses a system and a method for controlling electronic equipment. The control system comprises a signal acquisition module, a signal analysis module and a control signal generation module, wherein the signal acquisition module is used for receiving a digital signal transmitted by an analog-digital (AD) conversion module; the signal analysis module comprises a first judgment module and a second judgment module, wherein the first judgment module is used for receiving the digital signal, counting data exceeding a preset amplitude value of the digital signal in a preset period of time, judging whether the counted value exceeds a first preset critical value or not, and outputting a first judgment result; and the second judgment module is used for receiving the digital signal, judging whether the ratio of signals with frequency more than a preset frequency threshold value in the digital signal to the whole signal is higher than a second preset critical value or not, and outputting a second judgment signal; and the control signal generation module is used for receiving a first judgment result and a second judgment result, and generating a control signal for peripheral equipment when the first judgment result and the second judgment result are both affirmative values, and outputting the control signal to the peripheral equipment. The system and the method provided by the invention can be used for realizing blowing control of the electronic equipment.
