Or more than three remote control receivers, the number of which depends on actual needs, not limited to this.

In FIG. 1, the communication technologies used by the first remote control receiving device 41 and the second remote control receiving device 42 are respectively Radio Frequency (RF), WIFI, BitTorrent Protocol (abbreviated as BT), and infrared communication. The technology of the Infrared Data Association (IrDA) is selected, and the first remote control receiving device 41 and the second remote control receiving device 42 can use different communication technologies. For example, the first remote control receiving device 41 selects a radio frequency technology. The second remote control receiving device 42 selects an infrared communication technology, whereby the first remote control receiving device 41 can be matched with a remote controller 91 that uses the same radio frequency technology, and receives the first output of the remote controller 91 using the radio frequency technology. a remote control signal, and the second remote control receiving device 42 is matched with a wall control remote controller 92 that uses the same infrared communication technology, and receives the second remote control signal output by the wall control remote controller 92 using infrared communication technology. Thus, the user The remote control 91 and the wall remote control 92 can be used for remote control only, and the actual selection is used. The remote control method can be determined according to the needs of the user, and is not limited thereto.

The control unit 5 includes a control device 51 and a drive device 52.

The control device 51 has an analog digital conversion circuit 511, a zero detection circuit 512, and a controller 513.

The analog to digital conversion circuit 511 receives the input power and converts it to a digital power supply to provide the controller 513.

It is worth mentioning that the mains power can be directly used as the input power source, but the output of a wall control controller 93 can also be used as the input power source as shown in FIG. 1. At this time, the wall control controller 93 One of the receiving power sources is the mains.

The wall control controller 93 can be a TRAIC speed control wall controller 93 or a switch wall controller 94.

The DC inverter motor 8 operates.

The controller 513 controls the driving device 52 to output the DC variable frequency driving signal related to the input power source when determining that the input power source corresponding to the detection signal has been adjusted by the lead angle, because the wall control controller The output of 93 (TRAIC speed control wall controller or switch wall control controller) has been adjusted by the lead angle, that is, information about the relevant speed regulation has been included, so the controller 513 does not need additional control.

For example, when the user wants to use the remote controller 91 equipped with the radio frequency technology, it is only necessary to purchase the receiving unit 4 having the first remote control receiving device 41 equipped with the radio frequency technology, and then install it. If you want to use another remote control method that also uses RF technology (for example, the wall-controlled remote control 92), you only need to use the wall-controlled remote control 92 directly, no additional installation is required.

If the user wants to use another remote control method (for example, the wall-controlled remote controller 92 of the infrared communication technology) equipped with different communication technologies, it is only necessary to purchase the second remote control receiving device 42 using the external communication technology.

Moreover, even if the user loses the remote controller 91 or any kind of controller, other control methods can be used to control the control unit 5, It will face the dilemma that the remote control 91 is uncontrollable in the prior art.

Through the above description, the advantages of this embodiment can be summarized as follows:

1. By setting the control unit 5 and causing the control unit 5 to output the DC variable frequency drive signal to drive the DC variable frequency motor 8 to operate, stop, and adjust the operating speed, the speed of the ceiling fan can be controlled by DC frequency conversion, because As in the prior art, the speed reduction change is achieved in a step-down manner, so that the number of stages of the wire switch device 2 is not required to be fixed, and the speed adjustment effect of the wire 21 can be maintained.

Furthermore, by causing the control unit 5 to perform corresponding processing after receiving the input power, the pull signal, and the remote control input signal, a plurality of control modes can be simultaneously provided, so that the convenience in use can be increased, and It will face the dilemma that the remote control 91 is uncontrollable in the prior art.

2. The zero detection circuit 512 and the controller 513 are disposed in the control device 51, and the zero detection circuit 512 detects the zero crossing point of the input power to be provided to the controller 513. The controller 513 determines whether the input power has been adjusted by the lead angle, and outputs the corresponding control signal, whereby the control unit 5 can receive the input power that has been adjusted by the lead angle and perform corresponding processing. Therefore, the present implementation The example can be used together with the controller of the input power supply that has been directly adjusted by the lead angle, such as the TRAI speed control wall controller or the switch wall control controller, so that the system has excellent system amplification and convenience. .

3. By the receiver unit 4 pre-setting the receiving control device 43 corresponding to the plurality of interfaces or software (with the first remote control receiving device 41 and the second remote receiving device 42, etc.), the user needs to expand the control. In the mode, you only need to purchase the required remote control receiver and set it up. It is not only very expandable but also easy to expand. Moreover, these interfaces and software can be used according to actual needs. Changes, so can be adjusted in response to changes in market demand, with excellent market potential.
