USB (Universal Serial Bus) wireless connector, wireless connection system and USB wireless communication method

Abstract

The invention provides a USB (Universal Serial Bus) wireless connector used for outputting data of external equipment wirelessly, wherein the USB wireless connector comprises a USB physical interface, a USB-wireless network card interface conversion module and a wireless network card; the USB physical interface is used for being in data transmission with the external equipment; the USB-wireless network card interface conversion module is used for data conversion and interface conversion between the USB physical interface and the wireless network card; the wireless network card is used for outputting data converted by the USB-wireless network card interface conversion module by means of wireless communication, and receiving data transmitted by means of wireless communication. The invention further provides a USB wireless connection system including at least two USB wireless connectors. According to the USB wireless connector, the wireless connection system and the USB wireless communication method provided by the invention, the wireless connection is flexible, and the traditional USB transmission distance limit can be broken through.

Description

technical field [0001] The invention relates to the field of information communication, in particular to a USB wireless connector, a wireless connection system and a USB wireless communication method. Background technique [0002] In data communication, the physical interface of USB is simple to connect. In the case of excluding power supply and ground wiring, USB1.0, USB1.1, and USB2.0 only need two data connection lines (D+, D-), USB3.0 In addition to two data connection lines compatible with USBUSB1.0, USB1.1, and USB2.0, it also includes two pairs of high-speed data differential transmission lines (TX+, TX-, RX+, RX-). High transmission rate, the theoretical rate of USB2.0 can reach 480Mbps, and the theoretical rate of USB3.0 can reach 5Gbps, but due to problems such as line attenuation and interference, the transmission distance that can be realized by USB is limited, the longest is no more than 5 meters, although it can The distance is extended by re-amplifying the US...

[0002] In data communication, the physical interface of USB is simple to connect. In the case of excluding power supply and ground wiring, USB1.0, USB1.1, and USB2.0 only need two data connection lines (D+, D-), USB3.0 In addition to two data connection lines compatible with USBUSB1.0, USB1.1, and USB2.0, it also includes two pairs of high-speed data differential transmission lines (TX+, TX-, RX+, RX-). High transmission rate, the theoretical rate of USB2.0 can reach 480Mbps, and the theoretical rate of USB3.0 can reach 5Gbps, but due to problems such as line attenuation and interference, the transmission distance that can be realized by USB is limited, the longest is no more than 5 meters, although it can The distance is extended by re-amplifying the USB signal similar to the communication relay, but it makes the system complicated and inconvenient. In addition, the traditional USB physical cable cannot pass through walls and other physical obstacles, and the connection is extremely inflexible.
