Embodiment 1

[0027] Such as figure 1 , 2 As shown, the general wireless USB upgrade system in this embodiment 1 includes a device-side component 1 and a PC-side component 2;

[0028] The device end component 1 includes a USB extension interface 101, a first RF wireless module 102, and a first MCU microprocessor module 103:

[0029] The USB extension interface 101 is used to send the general USB wired data of the wired USB device 3 to the first MCU microprocessor module 103, and send the general USB wired data of the first MCU microprocessor module 103 to the wired USB device 3;

[0030] The first RF wireless module 102 is used to transmit wireless signals and receive wireless signals transmitted by the PC terminal component 2;

[0031] The first MCU microprocessor module 103 is used to analyze and process the general USB wired data of the wired USB device 3, convert the general USB wired data of the wired USB device 3 into a wireless signal and send it to the first RF wireless module 102...

Embodiment 2

[0040] Such as image 3 As shown, the difference between the general wireless USB upgrade system in the present embodiment 1 and the embodiment 1 is:

[0041] In order to provide power to devices without self-powered devices, the device-end component 1 also includes a battery power supply module 104, which is used to boost the battery voltage to the 5V required for USB power supply and then supply power to other modules of the device-side component 1 (USB extension interface) 101, the first RF wireless module 102, the first MCU microprocessor module 103) supply power.

[0042] Both the first RF wireless module 102 and the second RF wireless module 201 are 2.4G wireless modules. The 802.11 series of international local area wireless interconnection standard protocols are adopted to realize the conversion of USB wired data into wireless signals, with strong scalability.

[0043]The PC terminal component 2 is a Nano interface.

Abstract

The invention relates to a wireless universal serial bus (USB) upgrading system. The system is characterized by comprising an equipment end component and a personal computer (PC) end component, wherein the equipment end component comprises a USB expansion interface, a first radio frequency (RF) wireless module and a first micro-programmed control unit (MCU) microprocessor module; and the PC end component comprises a USB interface, a second RF wireless module and a second MCU microprocessor module. Compared with the prior art, the system has the advantages that: a radio signal connecting system is connected with wired USB equipment and a PC host computer, so that upgrading cost is low, performance is reliable, the system is suitable for most wired USB equipment and is easy to popularize; and the conventional wired USB equipment is fully utilized, and the waste of electronic components and pollution on the environment are avoided.

Description

technical field [0001] The invention relates to a wireless connection upgrade system for wired USB devices, and more specifically relates to a general wireless USB upgrade system for wireless connection between wired USB devices and PC hosts. Background technique [0002] With the continuous advancement of science and technology, PCs have been widely used in all aspects of people's work and life. Only in my country, the number of PCs (including notebook computers, servers, and workstations, etc.) has exceeded 100 million, and the relationship between a large number of devices and PC hosts All connections are via wired USB. [0003] However, with the increasing number of devices that need to be connected to the host PC, the shortcomings of the wired USB connection method appear. Due to the length limitation of the USB cable, various devices can only be placed near the host PC, which is difficult to meet actual needs, and a large number of The USB cables are also easy to get t...
