Dual network is isolated the SSD hard disk

Technical field

The utility model relates to a kind of SSD hard disk, is specifically related to a kind of dual network and isolates the SSD hard disk.

Background technology

Information security issue on the internet becomes and becomes increasingly conspicuous, and in order to guarantee the security of internal office work network, a lot of units forbid that with department the unit Intranet is connected the internet, has sometimes brought a lot of problems to routine work and can not connect outer net.In order to handle official business under the dual network environment, and satisfy security needs simultaneously, some unit has taked two hard disk measures, but this pair of hard disk measure can't realize mutual isolation, and when network switched, the information security of Intranet can't guarantee.In order to protect inner information security, be necessary to find and a kind ofly satisfy when connecting outer net, dual network isolation hard disk that can not access computer Intranet storage data.

The utility model content

The purpose of this utility model is to provide a kind of dual network to isolate the SSD hard disk, and mandatory physical is isolated between two SSD hard disks, can satisfy Intranet information security needs under the environment of dual network.

The utility model is by the following technical solutions:

A kind of dual network is isolated the SSD hard disk, and wherein, described dual network is isolated the SSD hard disk and comprised Intranet SSD hard disk and outer net SSD hard disk, and described Intranet SSD hard disk and outer net SSD hard disk be connecting interface change-over switch and power change-over switch respectively; Power change-over switch connects Intranet SSD hard disk and outer net SSD hard disk respectively, is Intranet SSD hard disk and the power supply of outer net SSD hard disk; The interface change-over switch connects mainboard through the SATA interface, and the SATA signal is sent to Intranet SSD hard disk and outer net SSD hard disk respectively.

As a kind of optimal way of the present utility model, described Intranet SSD hard disk and outer net SSD hard disk adopt physics to disconnect the isolated part switching.

As another optimal way of the present utility model, it is physical switch that described physics disconnects isolated part.

The beneficial effects of the utility model are:

The utility model can satisfy the needs of dual network (being Intranet and outer net), provide strong logical physical to isolate, the data of Intranet and outer net are stored on different SSD hard disks, two SSD hard disks can not be visited mutually, and when Intranet/outer net switched, the information in the buffer memory can not be stored, do not stay record, guaranteed to connect the security of Intranet information behind the outer net, can satisfy needs, improved the private network level of security simultaneously again outer net in higher unit of Intranet information requirements or the department.

Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can realize and obtain by specifically noted structure in following instructions or the accompanying drawing.

Embodiment

Below in conjunction with drawings and Examples the utility model is further described:

As shown in Figure 1, dual network is isolated the SSD hard disk and is comprised Intranet SSD hard disk and outer net SSD hard disk, and Intranet SSD hard disk and outer net SSD hard disk adopt physics to disconnect the isolated part switching, are physical switch in the present embodiment.Intranet SSD hard disk and outer net SSD hard disk be connecting interface change-over switch and power change-over switch respectively; Power change-over switch connects Intranet SSD hard disk and outer net SSD hard disk respectively, is Intranet SSD hard disk and the power supply of outer net SSD hard disk; The interface change-over switch connects mainboard through the SATA interface, and the SATA signal is sent to Intranet SSD hard disk and outer net SSD hard disk respectively.

The utility model be a kind of integrated two physically fully independently SSD(be solid storage hard disk), be connected on the mainboard by the SATA interface, by the self-defining control signal of SATA interface, when powering on, select one among internally two independent SSD and switch to system.The power supply of the SSD that does not choose simultaneously and signal wire will be cut off, even this moment, physical removal did not choose SSD that system is also had no effect.If selected SSD fault or not installation, then system shows as does not have SSD equipment.Choosing dish action only in 3 seconds after powering on effectively, after powering on, even switch choosing dish signal, inner handover module can not move yet.

Two SSD hard disks connect by high-speed analog switch, unification is connected on the mainboard by the SATA interface again, like this needn't be to mainboard through special design, and physical switch is set in the position of the outside handled easily of computing machine, the switching of control power supply and signal guarantees that synchronization has only a hard disk to power up.

Power change-over switch adopts speed-sensitive switch, is made up of two rejection gates, two field effect transistor and a not gate.As shown in Figure 2, elected go side E and input end A were all 1 o'clock, and then the S2 end is 0, and the S1 end is 1, VT1 conducting at this moment, and VT2 ends, and output terminal B is output as 1, and A=B is equivalent to input end and output terminal and connects.When gating E is 0, and input end A is 0 o'clock, and then the S2 end is 1, and the S1 end is 0, and at this moment VT1 ends, the VT2 conducting, and output terminal B is 0, A=B also is equivalent to input end and output terminal and connects.Elected go side E is 0 o'clock, and at this moment VT1 and VT2 are cut-off state, and circuit output is high-impedance state.When having only elected go side E to be high level, speed-sensitive switch just can be switched on, and can transmit information to B this moment from A; When input end A was low level, speed-sensitive switch cut out, and stopped transmission information.

The utility model is when system works: when before the start physical switch being placed Intranet, the system power-up start, do not load the WIFI module, switch to the Intranet pattern, only allow the Intranet SIM card to connect, do not load every other external interface, only keep a fixing Intranet USB interface, load the USB security module, SATA selects signal that hard disk is switched to Intranet SSD hard disk, outer net SSD hard disk does not power up, and guarantees that synchronization has only a hard disk to power up.

When before the start physical switch being placed outer net, the system power-up start, load the WIFI module, the 3G module is switched to the outer net pattern, only allow the outer net SIM card to connect, load all external interfaces, do not load the USB security module, and SATA selects signal that hard disk is switched to outer net SSD hard disk, and Intranet SSD hard disk does not power up, and guarantees that synchronization has only a hard disk to power up.

When system power-up start operation, manually pull the physics change-over switch, switching is not done by system, keeps current state, and after the system cut-off shutdown was started shooting again, SSD selected signal to discern the position of physical switch automatically, and does corresponding processing.
