[0035] in figure 1 In the overall circuit structure diagram, the power conversion circuit provides a stable output voltage for the microcontroller to work after power conversion; at the same time, the power sampling module collects the information of the connected power source through the A / D conversion and software algorithm in the microcontroller Calculate various electrical parameters connected to the power supply, including but not limited to voltage, period, current phase, and zero-crossing time of the power supply. These electrical parameters are provided for subsequent software control and calculation use; the microphone collects the motor suction port and dust collection The audio information between the bags is processed through the A / D conversion and software code in the microcontroller to determine whether the vacuum cleaner is blocked and the dust bag is full, and the result is reflected to the display and LED on the button module The lamp is displayed; the setting ...
