Physical isolation machine for multiple networks

Abstract

The invention discloses a physical isolation machine for multiple networks. The physical isolation machine comprises a mainframe which is internally provided with at least two mainboards, a display device with a video input port, an input device, a KVM (K Virtual Machine) board and a power mainboard, wherein the mainboards are physically isolated from each other, and each mainboard comprises a video output port and an input device input port; the KVM board is connected between the video output ports of the main boards and the input port of the display device and between the input device input ports of the mainboards and an output port of the input device; and the power mainboard is connected with the mainboards and the KVM board as well as with external power equipment. The physical isolation machine can be used for realizing physical isolation of the more than two networks and physical isolation of stored data among the different networks, only needs 1 second to 2 seconds for switching the networks, can be used for truly realizing the physical isolation of the networks and the stored data, and has the advantages of being easy to manage, small in size, high in performance, low in power consumption, and the like.

Description

technical field [0001] The invention relates to a mini-host with multiple networks physically isolated, in particular to a multi-network physically isolated machine. Background technique [0002] In 1999, the State Secrecy Bureau issued the "Notice on Strengthening the Administration of Government Online Information Confidentiality" No. 4 document, which stipulates that the confidential information network must be physically isolated from the public information network, and must not be stored on information devices connected to the public information network. , Processing and transmitting state secret information. The release of the No. 4 document has stirred up waves in the information security industry. In that year, some manufacturers successively developed single hard disk, dual hard disk physical isolation cards, and triple network physical isolation cards, which can save a computer. It can also ensure the physical isolation of the internal and external networks; the t...

Problems solved by technology

The release of the No. 4 document has stirred up waves in the information security industry. In that year, some manufacturers successively developed single hard disk, dual hard disk physical isolation cards, and triple network physical isolation cards, which can save a computer. It can also ensure the physical isolation of the internal and external networks; the technology of the three-network isolation card market is not yet mature, and there are basically no sales due to technical problems; but this product has some disadvantages: difficult to maintain, poor compatibility, long switching time between networks, switching When the frequency is high, it is easy to burn the hard disk and other problems

This technical solution solves the problem of switching between multiple computers. Multiple computers work at the same time, which not only consumes power, but also takes up a large volume. Every time they work, they need to control and turn on each computer at the same time, which causes problems such as inconvenient control.
