Abstract

A USB3.0 HUB that uses extremely high frequency microwaves for isolation, including a USB3.0 microwave transmitter and a USB3.0 microwave receiver, using an extremely high frequency EHF (Extremely High Frequency) with a frequency range of 60GHz, both The microwave communication between the communication can be automatically negotiated through the custom communication rules. The USB3.0 HUB at the USB3.0 microwave receiving end can connect four super high-speed USB3.0 terminal peripherals at the same time; during the USB3.0 microwave communication process, The microwave transmission device will not add any additional data in the data stream, so the USB3.0 signal is transparent during the transmission process using the microwave transmission device, and all super high-speed USB3.0 terminal peripherals that comply with the USB3.0 standard can work normally connect.

Description

technical field [0001] The present invention relates to the field of USB3.0 communication, in particular to the technical field of isolated communication between various USB3.0 terminal devices and computers, and specifically refers to a USB3.0 HUB using extremely high-frequency microwave isolation. [0002] The invention also relates to a method for controlling microwave communication between a USB3.0 microwave sending end and a USB3.0 microwave receiving end. Background technique [0003] As industrial electronic equipment has higher and higher requirements for data exchange speed, more and more industrial equipment has also begun to [0004] With the USB interface, the requirements for the reliability of the communication are getting higher and higher. However, the existing USB communication circuit has poor ability to resist the interference of the operating environment, and is extremely susceptible to static electricity and electromagnetic wave interference in the indu...
