Claim 2:
3. The DC brushless ceiling fan manual and remote control forward and reverse rotation control device according to claim 1, wherein the microcontroller unit of the remote controller module of the remote control and manual control switch group stores a remote control and manual forward and reverse rotation gear speed control protocol, and the manual controller module stores a gear speed change determination information, a forward and reverse rotation memory determination information and a remote control and manual forward and reverse rotation gear speed determination protocol memory information, and the remote controller module and manual controller module directly inputs voltage from the power supply, and after the first relay and the second relay of the remote controller module directly input voltage into the first wire body and second wire body respectively, the voltage is of a sine wave, and the voltage inputted from the first relay into the first wire body and outputted from the forward diode is in a positive half cycle, and the voltage inputted from the second relay into the second wire body and outputted from the backward diode is in a negative half cycle, and an outputted voltage waveform signal is detected by the first detector and the second detector of the manual controller module and used by the microcontroller unit to determine a rotational speed, and sends a control message to the motor driving unit to control the rotational speed of the ceiling fan brushless motor and perform a remote rotational speed control.
