Problems solved by technology

However, the traditional USB extender still needs to be manually switched on and off, which consumes a lot of manpower and material resources. At the same time, repeated plugging and unplugging will also cause damage to the device, and some hardware devices need to be updated after a period of time.
The traditional USB expansion device has a small number of extensions, and cannot control each USB port very well, which cannot meet the large-scale expansion of equipment

Abstract

The invention relates to a parallel type large-scale USB extension device, a working method and a system. The parallel type large-scale USB extension device comprises a plurality of USB extension boards, wherein each USB extension board is provided with a main USB bus interface, an auxiliary USB bus interface, a main communication interface, an auxiliary communication interface and a power interface and is connected with an upper computer through the main USB bus interface, the main communication interface and the power interface; the USB extension boards are further suitable for being mutually connected through the main and auxiliary USB bus interfaces and mutually connected through the main and auxiliary communication interfaces and the power interfaces so as to realize data transmission and communication connection among the USB extension boards. The USB extension boards of the parallel type large-scale USB extension device adopt the same structure, good interchangeability is realized, a plurality of USB interfaces can be extended, besides, manpower and equipment loss required by repeated insertion and extraction of equipment can be reduced, efficient office automation is facilitated, the operation is simple, the use is convenient, and the maintenance cost is low.

Description

technical field [0001] The invention relates to a USB extension device, in particular to a parallel large-scale USB extension device, a working method and a system. Background technique [0002] At present, some industries are increasingly pursuing efficient office automation. In the case of several external USB devices, if each device can be efficiently and accurately controlled, the work efficiency will be greatly improved. However, the traditional USB extender still needs to be manually switched on and off, which consumes a lot of manpower and material resources. At the same time, repeated plugging and unplugging will also cause wear and tear on the device, and some hardware devices need to be updated after a period of time. The traditional USB expansion device has a small number of extensions, and cannot control each USB port very well, so it cannot meet the large-scale expansion of equipment. Contents of the invention [0003] The purpose of the present invention is ...
