Abstract
The utility model relates to a computer network security controller. The development of the computer network also brings potential security hazards to the computer information of users, and network information interception, information attacks, virus spreading and the like exist and take place all the time. The product comprises a microprocessor (1), wherein the microprocessor is connected with a relay driver (2), the relay driver is respectively connected with a computer network control relay (3) and a computer power control relay (4), the computer network control relay is connected with a computer network card (5), the computer power control relay is connected with a computer hard disk (6), and the microprocessor is connected with a computer PCI (Peripheral Component Interconnect) interface (7). The computer network security controller is used for protecting the security of the hard disk information of a computer and the security of the networked computer, and moreover, the computer network security controller structurally chooses an optimal form in terms of the structure and simplest connection relation in terms of circuit combination, and realizes the intelligent control of each part of the computer.
Description
Technical field:
The utility model relates to field of computer information security, is specifically related to a kind of network security controller of computer.
Background technology:
The fast development of Along with computer technology and network makes computing machine become people's indispensable instrument in work, studying and living.Equally, development of computer network has also been brought the potential safety hazard of subscriber computer information, and the network information is stolen, information attack, virus disseminating etc. all exist all the time and take place.In order to solve the subscriber computer information security issue; People have taked many measures and method, comprise adopting hard disk to isolate the two hard disk work of card control, two two hard disk work of different operating system control, manually control two hard disks technical measures and means such as work respectively.These methods all exist technical defective to some extent, and what have can not guarantee " network hacker " in the attack of network-side to user's hard disk information, and the needs that have are shut down computer and could be changed hard disk work.
The utility model content:
The purpose of the utility model is to the problem of above-mentioned existence a kind of network security controller of computer to be provided, and can effectively guarantee the safety of subscriber computer information.
The purpose of the utility model realizes through following technical proposals:
Network security controller of computer; Its composition comprises: microprocessor; Described microprocessor connects relay driver, and described relay driver connects computer network pilot relay and computer power supply pilot relay respectively, and described computer network pilot relay connects the computing machine network interface card; Described computer-electrical source controller connects hard disc of computer, and described microprocessor is connected on the computer PCI interface.
Described network security controller of computer, described relay driver adopts DS2003CM.
Beneficial effect:
1. the utility model adopts microprocessor pilot relay driver; And then difference control computer network interface card and hard disc of computer; Efficiently solve information safety protection problem and the safeguard protection problem after the computer networking of the hard disk of computing machine; And structurally selected optimum way, on combination of circuits, selected the annexation of simplifying most, accomplished the Based Intelligent Control between the each component of computer.
2. the utility model is simple in structure, is easy to popularize the intelligent hard disc control card of the utility model design, and its components and parts are the parts that are prone to purchase on the market, and is therefore with low cost, is easy to produce, and is easy to popularize.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Embodiment:
Embodiment 1:
As shown in Figure 1; Network security controller of computer, its composition comprises: microprocessor 1, described microprocessor connects relay driver 2; Described relay driver connects computer network pilot relay 3 and computer power supply pilot relay 4 respectively; Described computer network pilot relay connects computing machine network interface card 5, and described computer-electrical source controller connects hard disc of computer 6, and described microprocessor is connected on the computer PCI interface 7.
Embodiment 2:
Described network security controller of computer, described relay driver adopts DS2003CM.
The course of work:
The control procedure of the utility model:
Init state: computing machine networking pilot relay 3 breaks off, and subscriber computer and computer network break off; 4 adhesives of computer power supply pilot relay, the computer-electrical supply socket is communicated with, and computer power supply powers up to the secret hard disk of subscriber computer, secret hard disk work.
Microprocessor sends instruction, pilot relay 3 adhesives of computing machine networking, and subscriber computer is communicated with computer network, and computer power supply pilot relay 4 breaks off, and the computer-electrical supply socket is not communicated with, the secret hard disk outage of subscriber computer, secret hard disk is not worked.
Be that computing machine networking pilot relay 3 opposes with computer power supply pilot relay 4 each other, when pilot relay 3 adhesives of computing machine networking, computer power supply pilot relay 4 must break off.When computing machine networking pilot relay 3 breaks off, the 4 inevitable adhesives of computer power supply pilot relay.Mainly be to guarantee that secret hard disk of subscriber computer and computer network oppose each other.That is to say that when the secret hard disk of subscriber computer was worked, subscriber computer is inevitable to be broken off with network; When the secret hard disk of subscriber computer is not worked, the inevitable and network-in-dialing of subscriber computer.It is hereby ensured subscriber computer the networking state under do not stolen security information by " network hacker ".
Claims (2)
1. network security controller of computer; It is characterized in that: comprise microprocessor; Described microprocessor connects relay driver, and described relay driver connects computer network pilot relay and computer power supply pilot relay respectively, and described computer network pilot relay connects the computing machine network interface card; Described computer-electrical source controller connects hard disc of computer, and described microprocessor is connected on the computer PCI interface.
2. network security controller of computer according to claim 1 is characterized in that: described relay driver adopts DS2003CM.
