Abstract
The utility model relates to a universal serial bus (UBS) interface isolation control system of a multi-security-domain computer and relates to a computer control system. The USB interface isolation control system is formed by a multi-way selection interface device and USB plugs. The multi-way selection interface device is formed by more than one USB interface, and all the USB interfaces are connected with a USB plug circuit. A switch is respectively arranged on all connection circuits of the USB interfaces and the USB plugs. The universal serial bus (UBS) interface isolation control system of the multi-security-domain computer is reasonable in design, good in generality, low in cost and simple to operate and strengthens safety coefficient in use. Simultaneously, a plurality of external storages can be connected with the computer simultaneously.
Description
Technical field
The utility model relates to a kind of computer control system, relates in particular to a kind of USB interface isolation control system of many security domains computing machine.
Background technology
At present, in large-scale working environment, Inside and outside network this minute arranged; in outer net and system that Intranet is separated, usually use network interface, the modes such as hard-disc storage solve; because each security system all can conduct interviews to USB interface, often can bring unsafe hidden danger to exterior storage.
Summary of the invention
The utility model is intended to for the deficiency that exists in background technology, and the USB interface isolation control system of a kind of many security domains computing machine that provides.
The USB interface isolation control system of a kind of many security domains computing machine of the present utility model, to be consisted of by multichannel option interface device and USB plug, described multichannel option interface device is made of the USB interface that is no less than, all USB interface all with the USB plug connection.
As further improvement of the utility model, be equipped with switch on all USB interface and the connection line of USB plug.
The USB interface isolation control system of a kind of many security domains computing machine of the utility model, reasonable in design, universal performance is good, and cost is low, and is simple to operate, and the safety coefficient when having strengthened using can a plurality of exterior storage connect with computer simultaneously simultaneously.
