Detailed description of the invention

Embodiment of the present utility model is described in detail, thereby to this below in conjunction with drawings and Examples Utility model how application technology means solve technical problem and reach the process that realizes of technology effect and can fill Sub-argument solution is also implemented according to this.

This utility model provides a kind of safety controller for computer, as it is shown in figure 1, include that Intranet exchanges Machine 100, outer network switch 200, switching switch 300, computer network interface 500, server 600, Computer safety monitoring device 700 and computer isolating device 800, described outer network switch 200 and institute State Intra-Network switch 100 be connected with described computer network interface 500 by described switching switch 300 or Disconnect；Described computer network interface 500 is connected with described server 600；Described computer security is supervised Control device 700 is all connected with described server 600 with described computer isolating device 800；Also include controlling Circuit 400, the input of described control circuit 400 is connected with described computer network interface 500, defeated Go out end to be connected with described switching switch 300.

Described computer isolating device 800 solves inner net computer and outer net computer data cannot safe number Problem according to transmission；When needing data to transmit between outer net computer and inner net computer, the data of transmission It is required for by entering another computer after described computer isolating device 800 isolation caching.Same 800 and one compunication of computer isolating device described in time, isolates with other computer hardwares.

Described computer safety monitoring device 700 achieves the real-time monitoring to described server 600, it is ensured that The safety of described server 600.

As in figure 2 it is shown, described server 600 includes hard disc module 610 and energy supply control module 620, Described hard disc module 610 is connected with described energy supply control module 620.

As it is shown on figure 3, described hard disc module 610 includes system start-up hard disk 611, internal hard drive 612 With external hard disc 613, complete physical isolation between three pieces of described hard disks；Described system start-up hard disk 611 It is connected with described energy supply control module 620；Described internal hard drive 612 and described energy supply control module 620 Connect；Described external hard disc 613 is connected with described energy supply control module 620.

Described system start-up hard disk 611, internal hard drive 612 and external hard disc 613 are mechanical hard disk.

In mechanical hard disk, all of disc is incorporated in a rotary shaft, is parallel between each disc sheet, Having a magnetic head on the storage face of each disc, the distance between magnetic head and disc is than the diameter of hairline The least, all of magnetic head is associated on a magnetic head control device, magnetic head control device be responsible for the fortune of each magnetic head Dynamic.Magnetic head can move along the radial direction of disc, adds the high speed rotating of thousand of turns per minute of disc, magnetic Head just can be positioned at the read-write operation specifying position enterprising row data of disc.Hard disk as precision equipment, Dust is its formidable enemy, it is necessary to fully seal.

In the present embodiment, the described independent storage system startup file of system start-up hard disk 611 and system are just The basic data often run, single system deposits the invasion that system can be made from virus, it is ensured that system Stable operation.Described internal hard drive 612 individually deposit for internal network user read and amendment interior Portion's data, this application makes internal data completely isolated with the external world, it is therefore prevented that the loss of security information.Institute The external hard disc 613 stated individually deposits the external data read for external network user, so, i.e. Just the virus of external network invasion also cannot be introduced into internal network and system, makes loss be minimized.

Described energy supply control module 620 is to described system start-up hard disk 611, internal hard drive 612 and outer Portion's hard disk 613 is powered, and when described server 600 is started shooting, system start-up hard disk 611 adds all the time Electricity；When system is in interior net state, internal hard drive 612 is powered up by described energy supply control module 620, To external hard disc 613 power-off；When system is in outer net state, described energy supply control module 620 is right External hard disc 613 powers up, to internal hard drive 612 power-off.

Described control circuit 400 uses closed control circuit, closed control circuit to refer to control object and deposits Control circuit in feedback contact.Open-loop control circuit simple in construction, low cost, but control accuracy is relatively low. For keeping the constant of rotating speed in systems, can be added some and measure comparing element composition closed loop system.

Described computer network interface 500 uses RJ-45 interface, RJ-45 interface to be exactly that we are the most normal The network device interface seen, is commonly called as " crystal head ", and technical term is RJ-45 adapter, belongs to twisted-pair feeder Ethernet interface type.RJ-45 plug can only insert along fixed-direction, be provided with a plastic shrapnel with RJ-45 slot blocks in case anti-avulsion falls.This interface is at 10Base-T Ethernet, 100Base-TX ether Can use in net, 1000Base-TX Ethernet, transmission medium is all twisted-pair feeder, but according to band Wide difference also has different requirements to medium, when particularly 1000Base-TX gigabit Ethernet connects, CAT5E UTP cable to be used, it is ensured that also to use 6 class lines if stable high speed.

A kind of safety controller for computer that this utility model provides, have employed independent insulating power supply to firmly Dish is controlled, it is therefore prevented that the loss of security information；When connecting Intranet and outer net at the same time, can accomplish Two networks are the most all complete physical isolation, thus protect Intranet will not be entered by the user of outer net Invade, reach the mesh ground of network security completely；The hard disk used in Intranet and the hard disk of outer online use In information completely isolated, outside so can thoroughly solving the physical isolation problem of Intranet and outer net and preventing The incoming Intranet of computer virus of net, it is achieved network security and prevent computer virus incoming, is to calculating The basic solution of the isolating problem of machine network；This utility model both can provide the user online easily and search Rope and the function of surfing the Net of business relations, solve and both need network to surf the Net, and has and can reach to protect computer The information security requirement of internal data.

Also, it should be noted term " includes ", " comprising " or its any other variant are intended to non- Comprising of exclusiveness, so that include that the commodity of a series of key element or system not only include those key elements, But also include other key elements being not expressly set out, or also include for this commodity or system institute Intrinsic key element.In the case of there is no more restriction, by statement " include one ...... " key element that limits, It is not precluded from there is also other identical element in the commodity including described key element or system.

Described above illustrate and describes some preferred embodiments of the present utility model, but as it was previously stated, should When understanding that this utility model is not limited to form disclosed herein, it is not to be taken as other embodiments Eliminating, and can be used for other combinations various, amendment and environment, and can be in utility model described herein In contemplated scope, it is modified by above-mentioned teaching or the technology of association area or knowledge.And people from this area The change that carried out of member and change, the most all should in this practicality newly without departing from spirit and scope of the present utility model In the protection domain of type claims.
