Single-interface electronic isolation dual-solid-state disk

Abstract

The invention discloses a single-interface electronic isolation dual-solid-state disk which comprises an inner network solid-state disk and an outer network solid-state disk. The single-interface electronic isolation dual-solid-state disk also comprises a switchover maintaining control circuit which ensures that only one disk is energized in the same time; the inner network solid-state disk and the outer network solid-state disk are respectively connected with a computer power module through the switchover maintaining control circuit; and data output ends of the inner network solid-state disk and the outer network solid-state disk are connected with a computer main board by the same data interface. The single-interface electronic isolation dual-solid-state disk has a simple structure, is very easy to realize, can ensure that the inner network solid-state disk and the outer network solid-state disk separately operate without influencing each other, thereby the confidentiality requirement in work is satisfied; the inner network / outer network switching is realized only after the computer is powered off and an inner network selector switch and an outer network selector switch on a control circuit are rearranged, and the destination network is obtained by restarting the computer; and information in cache in the period is cleared due to power interruption without records, thereby the safety of information is ensured.

Description

technical field [0001] The invention relates to a data storage device, in particular to a single-interface electronic isolation double solid-state hard disk. Background technique [0002] The large-scale commercial use of the Internet has greatly improved the work efficiency of enterprises, institutions and government departments, but at the same time, it is also facing increasingly serious problems such as computer viruses and hacker attacks. As part of the information and data of enterprises, institutions and government departments are confidential information, once the computer is attacked by viruses or hackers and the confidential information is leaked, it will cause huge losses. In order to ensure the security of the internal information network, many units and departments prohibit the unit information intranet from connecting to the Internet, which causes a lot of inconvenience in daily work and affects work efficiency. In order to ensure office security under the dua...

Problems solved by technology

Since some information and data of enterprises, institutions and government departments are confidential information, once the computer is attacked by viruses or hackers and the confidential information is leaked, it will cause huge losses.

In order to ensure the security of the internal information network, many units and departments prohibit the unit information intranet from connecting to the Internet, which causes a lot of inconvenience in daily work and affects work efficiency

In order to ensure office security under the dual network environment of the Internet and intranet, many units have adopted dual hard disk isolation measures, resulting in a situation where one computer is connected to one network and one staff member is equipped with two computers. The investment is huge and not only cannot improve work efficiency , but also increased the unnecessary economic burden

The invention patent with the authorized announcement number 201662811U discloses a dual-network isolation SSD hard disk. The dual-network isolation SSD hard disk includes an internal network SSD hard disk and an external network SSD hard disk. The internal network SSD hard disk and the external network SSD hard disk are respectively connected to the interface switching switch. And the power switch, the power switch is connected to the internal network SSD hard disk and the external network SSD hard disk respectively, and supplies power for the internal network SSD hard disk and the external network SSD hard disk. For hard disks and external network SSD hard disks, the power switching switch described in the invention patent is composed of two NOR gates, two field effect transistors and one NOR gate. Since the circuit depends on high and low level signals, it is susceptible to external influences and abnormalities, resulting in If the working status is out of lock, it cannot work reliably, and it is easy to cause errors in the working status of the hard disk and leak confidential information.
