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 present invention relates to a tandem mass USB expansion apparatus, and a working method and system. The tandem mass USB extension apparatus comprises: a plurality of USB expansion boards. Each USB expansion board is provided with a master and a slave USB bus interface and a master and a slave communication interface, and is connected with an upper computer via the master USB bus interface and the master communication interface; and the interconnection of the master and the slave USB bus interface, and the interconnection of the master and slave communication interface are suitable to be performed among the USB expansion boards, so as to realize data transmission and communication connection among the USB expansion boards. According to the tandem mass USB expansion apparatus disclosed by the present invention, manpower required by repeated insertion and extraction of equipment, and equipment wear and tear can be reduced, realization of efficient office automation is facilitated, and simple operations, convenient use, and low maintenance costs are realized.

Description

technical field [0001] The invention relates to a USB extension device, in particular to a series-type 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 object of the present invention i...
