Physic separated controlling circuit and computer system of physic separated network

Abstract

The invention consists of MCUú¼IDE control circuit, network card circuit and relay control circuit. Multi connecting ports are configured to the network card, and they are used to connect to different networks. The invention also includes a computer system containing the physical isolation circuit, by which the data in private network and public network is separately transmitted.

Description

technical field [0001] The invention relates to network security technology, in particular to the technology of physically isolating computer terminals that use internal and external networks, that is, local area networks and the Internet, especially a physically isolated circuit and a physically isolated network computer system including the physically isolated control circuit. Background technique [0002] With the development of information technology and the widespread popularization of computer products, the network has been closely related to people's life and work. Generally, computer terminals work in the state of the second network, that is, they are connected to the internal network and the external network at the same time, or the local area network and the Internet. . However, while the network brings us high-efficiency, convenience and massive information, it will inevitably encounter viruses, hackers and confidential information thieves, making the network secu...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, in order to achieve physical isolation for computer terminals working on the second network, dual motherboards, dual network cards and dual hard disks are used, which not only takes up too many resources, but also has hidden dangers in network security.
