Transmission system of wireless peripheral device and matching method thereof

The present invention relates to a wireless peripheral device, and more particularly to a wireless peripheral device transmission system for pairing different wireless peripheral devices with a same wireless receiver to enable different wireless peripheral devices to communicate with the same computer host and Its pairing method.

The advancement of science and technology has made the application of personal computers an indispensable part of modern life. With the advancement of technology, computer peripheral devices, such as wireless keyboards, wireless mice, wireless joysticks, etc., have also begun to connect from personal computers to wireless links. A wireless peripheral transmission system usually includes a transmitter and a receiver. The transmitter is disposed inside the wireless peripheral device, and the receiver is connected through a connection port (such as a USB port) of the personal computer to enable the transmitter. The signal is transmitted between the receiver and the receiver through a specific wireless communication protocol, and can communicate with the personal computer through the wireless peripheral device.

The transmission system of the previous wireless peripheral device is a transmitter and a receiver, and a receiver needs to occupy a connection port on the personal computer. When the user wants to replace different wireless peripheral devices, or use multiple wireless peripheral devices at the same time, it is necessary to replace the corresponding receiving end or add a corresponding receiver. However, the number of ports connected to a personal computer is rather limited. When the connection of the personal computer is insufficient, the user needs to unplug the other receivers to plug in the receiver of the wireless peripheral device to be used. This causes inconvenience and trouble in use. Furthermore, the commercially available wireless peripheral devices are all sold with a receiver attached. When the user accidentally loses the receiver, the wireless peripheral device manufacturer will not be able to use the wireless peripheral device if the receiver is not separately sold. It is also quite inconvenient for users.

In view of the above problems, the present invention provides a transmission system of a wireless peripheral device and a matching method thereof, thereby solving the problem of inconvenience in use by coping with different wireless peripheral devices in a manner of replacing different wireless receivers.

In an embodiment of the present invention, the control unit accumulates the data received by the receiving unit to generate a check value, and then compares with an identification code transmitted by the transmitting unit of the wireless peripheral device to verify that the received data is received. Is the information correct? However, the mode of comparison of the present invention is not limited thereto.

When the identification code comparison fails, the control unit will control the receiving unit to stop operating and discard the received data, as by step S241. When the identification code comparison is successful, the control unit overwrites the identification code stored in the temporary storage area with the previous identification code stored in the memory unit, as in step S242. The previous identification code is the identification code of the previous wireless peripheral device paired with the wireless receiver.

Finally, the wireless receiver is re-communicated with the host computer through a USB communication protocol corresponding to the wireless peripheral device to be paired, so that the wireless receiver can be paired with the wireless peripheral device, as by step S250. When the wireless receiver is successfully paired with the wireless peripheral device, the user can use the wireless receiver to enable the wireless peripheral device to communicate with the host computer.
