BEST MODE FOR CARRYING OUT THE INVENTION The wireless transmission USB far-end activation method of the present invention is applied to a computer 20 using wireless peripheral equipment, and particularly to a computer system using a USB keyboard and mouse.

In the system structure of the present invention described above, as shown in FIG. 1, a detection mechanism 11 is installed and dedicated to the detection of the signal of the USB receiver 10. The detection mechanism 11 controls the microprocessor 12. When receiving a signal, the USB receiver 10 is detected and the USB receiver 10 is detected, and if there is a signal, the remote remote wakeup (REMOTE WAKE U
P), and if there is no signal, let the system maintain the state of power saving standby (SUSPEND).

The above-mentioned detection mechanism 11 uses an RC charge / discharge circuit to conduct electricity at a certain time to supply power, and causes the far-end activation function to detect the presence or absence of an activation signal. If there is a signal, the direct awakening function is activated. To run the system and, if there is no signal, keep the system in a power-saving standby state, thereby achieving the power saving function.

The above-mentioned detection mechanism 11 uses the watch dog time-out (WATCH DOG TIME OUT) method, conducts electricity at a certain time to supply electric power, and causes the far-end activation function to detect the presence or absence of an activation signal. If there is a signal, the wakeup function is directly executed to operate the system, and if there is no signal, the system is kept in the power saving standby state.

The detection mechanism 11 can also be a software or hardware device with similar operational characteristics as described above,
When the far end activation function detects the signal of the wireless peripheral equipment by using the detection mechanism 11, it indicates that the RF module of the USB peripheral equipment has the activation operation, that is, it directly enters the wakeup function. If the RF module is not in operation, the system keeps the power saving standby state, thereby reducing the time required for USB signal recognition and increasing the overall efficiency.

According to the method of the present invention, when the USB peripheral equipment is not operating, the system is kept in the power saving standby state,
The power consumption during standby can be saved, and both the receiver and the transmitter have good transmission quality.
