Ceiling fan and controller thereof

Abstract

The invention discloses a ceiling fan and a controller thereof. The controller of the ceiling fan comprises a wall control device and a control device. The wall control device comprises a zero crossing detection circuit, a wall control MCU circuit and a signal processing circuit. The control device comprises a pulse detection circuit, a controller circuit and a motor drive circuit. The zero crossing detection circuit detects the zero crossing point of an alternating-current power supply signal input through an alternating-current input end. When the wall control MCU circuit detects the zero crossing point of the alternating-current power supply signal, a coding control signal is output. The signal processing circuit controls the disconnection time number pulse of a path between the alternating-current input end and the control device according to the coding control signal, and the detection circuit detects the received missing pulse number of an alternating-current power supply. The controller circuit obtains a matched motor control signal, and controls the motor drive circuit according to the motor control signal to drive a motor to do corresponding actions. Therefore, the technical problems that in the prior art, when the ceiling fan is controlled to work through wireless remote control, noise interference is caused, the electric quantity of a remote controller is not enoughand management is not convenient are solved.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to a ceiling fan and a controller thereof. Background technique [0002] At present, the DC brushless ceiling fans on the market mainly adopt the wireless remote control scheme, which is mainly divided into two parts: the transmitter and the receiver. The transmitter and the receiver are controlled by wireless radio frequency signals, and the receiver and the ceiling fan are assembled together and installed on the ceiling. , the user uses the transmitter to control the ceiling fan to work. Although the wireless remote control solution is easy to use, there are also some problems: [0003] Wireless signals are easily interfered by noise in the environment. When multiple remote controls are used in the same place at the same time, wireless signals of the same frequency will interfere with each other. [0004] Electromagnetic radiation is also generated during the radio frequency contro...
