The invention provides a ceiling fan controller, which is used for solving the technical problem that a wire pipe paved by the ceiling fan controller needs to be installed and debugged for a long time in the prior art.
In one embodiment of the present invention, as shown in fig. 1, a ceiling fan controller includes a wall control device 200 and a control device 300, wherein the wall control device 200 is connected to an ac input terminal 100, and the wall control device 200 is connected to the control device 300 through a power line. The wall control device 200 comprises a zero-crossing detection circuit 201, a wall control MCU circuit 202 and a signal processing circuit 203, and the control device 300 comprises a pulse detection circuit 403, a controller circuit 402 and a motor driving circuit 401.
The zero-crossing detection circuit 201 detects a zero-crossing point of the ac power signal input by the ac input terminal 100, the wall control MCU 202 outputs a coding control signal when detecting the zero-crossing point of the ac power signal, the signal processing circuit 203 controls the number of times of switching off the path between the ac input terminal 100 and the control device 300 according to the coding control signal, so that the ac power signal output to the control device 300 is an ac power signal with a missing pulse number, at this time, the purpose of loading the coding signal into the ac power signal is achieved, and it should be noted that the number of times of switching off the path between the ac input terminal 100 and the control device 300 is one type of coding method, and it is understood that the coding method is not limited to this type of coding method, and other coding methods may be adopted herein, such as a switching on/off time period (limited within a time range that does not affect the normal operation of the motor, and may be specifically determined by the size of an internal energy storage element of the controller circuit 402 and the power consumption of the controller circuit 402). Subsequently, the pulse detection circuit 403 detects the number of missing pulses of the ac power supply received by the control device 300, and the controller circuit 402 obtains a motor control signal matched with the number of missing pulses, and controls the motor driving circuit 401 to drive the motor to perform a corresponding action according to the motor control signal. For example, 2 missing pulses represent starting of the motor, 3 missing pulses represent low speed, etc., thus, the present application realizes the encoding of the control signal in the wall control device 200 and the decoding of the control device 300, so as to directly superimpose the control signal on the current power line, so as to solve the problems of noise interference, electromagnetic wave pollution, insufficient electric quantity of the remote controller, inconvenient management, etc. when the wireless remote control ceiling fan works in the prior art. In addition, although the present application loads the control signal by instantaneous on-off at the zero crossing point, so that there is an instantaneous interruption in the process of supplying the ac power signal to the subsequent circuit, since the controller circuit 402 has an internal energy storage element, the instantaneous on-off of the ac power signal or the on-off of the ac power signal in a short time does not affect the normal operation of the motor driving circuit 401, and the limit value of the power-off time is determined by the internal energy storage element of the controller circuit 402. In addition, in the prior art, the control signal is generally a high-low level signal or a pulse signal, if the variable waveform is directly loaded into the alternating current according to the application, corresponding components are easy to burn out.

Therefore, the ac power signal output by the wall control device 200 and input by the control device 300 is an ac power signal with missing pulses, at this time, the sixth chip U6 can determine the control signal by detecting the number of missing pulses of the ac power signal, so as to send out the corresponding motor control signal to control the motor to operate, and when the missing pulses occur, the loss of the ac power signal in a short time does not affect the normal operation of the control motor because the sixth chip U6 itself has the twentieth capacitor C20 of the energy storage element and the sixth internal power V6.
