Problems solved by technology

However, the long-distance transmission of USB signals by optical fiber or signal amplification requires independent network or optical fiber, which greatly increases the cost; and the use of MCU to transmit USB files through network cables, although the TCP / IP protocol can be used on existing network cables. running, but the host needs to install a specific driver or program to obtain data, and has poor compatibility with USB devices; these are unexpected for those skilled in the art

Abstract

The invention relates to the technical field of information transmission, in particular to a system and method for remote transmission of USB data. The system comprises a first connecting module connected with a personnel computer and a second connecting module connected with a USB device, the first connecting module and the second connecting module both comprise an FPGA chip, a network PHY and aUSB PHY, and internet data interaction is conducted between the first connecting module and the second connecting module is conducted according to a TCP / IP protocol, and therefore remote transmissionof the USB data is achieved. The system has the advantages of long transmission distance and convenient use.

Description

technical field [0001] The invention relates to the technical field of information transmission, in particular to a system and method for long-distance transmission of USB data. Background technique [0002] The USB bus (Universal Serial Bus, peer serial bus) is a widely used high-speed data transmission interface, and the superiority of the USB technology is becoming more and more obvious, and there are more and more devices supporting the USB technology, but the difference between the USB device and the USB host The distance between them is limited by the extension cable and must be used within the specified length; in some special applications, the distance between the USB device and the host is required to be tens of meters or hundreds of meters, and if the USB cable is extended , it is easy to cause unstable transmission, resulting in transmission failure, which will bring a lot of inconvenience to the occasions where the USB device needs to be used at a long distance. ...
