The principle of the present application is explained below with reference to fig. 1 to 12:
when the knob switch circuit outputs a control signal, the second chip U2 generates a coding control signal according to the control signal, the second chip U2 controls the on or off of the controlled silicon Q1, when the controlled silicon Q1 is disconnected, an alternating current power supply signal flows through the alternating current power supply signal line, when the controlled silicon Q1 is closed, no alternating current power supply signal flows through the alternating current power supply signal line, the power-off time can be set, such as 40MS, power supply is recovered after power-off is completed, power is re-supplied after a certain time interval, multiple power-off is executed according to different motor control signals to be executed, and power supply is recovered after a command is sent. Assuming that the signal transmission time is 2S, when the number of times of flash-off of 40MS occurs in 2S is 2, it represents one fan rotation speed, and when the number of times of flash-off of 40MS occurs in 2S is 3, it represents another fan rotation speed, the controller circuit can output a corresponding motor control signal according to the number of times of flash-off to control the motor to make a corresponding action to adjust the fan rotation speed.
Therefore, the ac power signal output by the wall control device 20 and input by the control device 40 is an ac power signal with a preset flash time, and at this time, the sixth chip U6 can determine the control signal at this time by detecting the detection flash frequency of the ac power signal to send a corresponding motor control signal to control the motor to operate, and when the motor is flashed within the preset flash time, because the sixth chip U6 itself has the energy storage element twentieth capacitor C20 and the internal sixth power V6, the absence of the short-time ac power signal does not affect the normal operation of the motor. In the present application, by encoding the control signal into the ac power supply signal, the operation of the motor is not destroyed while the voltage range of the ac power supply signal is not changed. In addition, compared with a wireless control scheme, the control of a remote controller is reduced, and the management is facilitated.
