In an embodiment, the host 100 is a mainboard, but is not limited thereto. The host 100 is an electronic device including a connector to connect a peripheral apparatus to extend functions. The host 100 is a desktop computer, a notebook computer, or a mobile phone.
As shown in the figure, the host 100 includes a host controller 120, a first signal transmission unit 140, a host connector 160, and an isolation element 180. The host controller 120 is configured to generate a control signal S1 to control the fan 400. In an embodiment, the control signal S1 is a fan rotation control signal, a light emitting diode control signal, or the like. In an embodiment, the host controller 120 is a fan controller.
The first signal transmission unit 140 is electrically connected to the host controller 120 to receive the control signal S1. In an embodiment, the control signal is a digital signal. As shown in the figure, the host controller 120 transmits the control signal S1 to the first signal transmission unit 140 by using a communications protocol through a frequency transmission line CLK and a data transmission line DATA. The communications protocol is a communications protocol commonly applied in a computer system, such as an SMBUS communications protocol, an I2C communications protocol, or an SPI communications protocol.
After receiving the control signal S1, the first signal transmission unit 140 generates a first carrier W1 to carry the control signal S1. A technology for carrying a digital signal by using a carrier in a modulation manner is known in the field, and details are not described herein again. In an embodiment, the first signal transmission unit 140 is a modulation processing unit, but is not limited thereto. The first signal transmission unit 140 is a modulation/demodulation processing unit.
As shown in the figure, the host connector 160 is configured to connect the fan 400. The first signal transmission unit 140 is electrically connected to the host connector 160. In this embodiment, the host connector 160 is a fan connector. The fan connector includes a power pin 162 and a ground pin 164.

In addition, the first signal transmission unit 140 transmits the first carrier W1 by using at least one of the power pin 162 and the ground pin 164. In this embodiment, the first signal transmission unit 140 transmits the first carrier W1 by using the power pin 162. However, it is not limited thereto. The first signal transmission unit 140 alternatively transmits the first carrier W1 by using the ground pin 164.
In an embodiment, the first signal transmission unit 140 alternatively generates two carriers to carry different control signals, and respectively transmits the two carriers by using the power pin 162 and the ground pin 164.
As shown in the figure, in an embodiment, in addition to providing the control signal S1 to the first signal transmission unit 140, the host controller 120 is further electrically connected to the host connector 160 to provide electric power required for operating the fan 400 and functions supported by hardware of the original host connector 160. In an embodiment, the host controller 120 provides electric power (for example, 12V) to drive the fan 400 by using the power pin 162. The host controller 120 controls the fan 400 to rotate by using a pulse width modulation control pin, and obtains rotation speed information of the fan 400 by using a feedback signal pin (not shown in the figure).
In an embodiment, by appropriately adjusting a frequency of the first carrier W1, the first signal transmission unit 140 transmits the first carrier W1 to the fan 400 by using the power pin 162 or the ground pin 164 to perform control while the host controller 120 provides electric power for the fan 400 by using the power pin 162 or the ground pin 164.
