Description
Technical field
The utility model relates to a kind of computer network data safety governor, relates to technical field of the computer network.
Background technology
Computing machine is a kind of robot calculator device for supercomputing, can carry out numerical evaluation, can carry out logical calculated again, also have store-memory function.Can run according to program, automatically, the modernization intelligent electronic device of high speed processing mass data.Being made up of hardware system and software systems, the computing machine not installing any software is called bare machine.Can be divided into supercomputer, industrial control computer, network computer, personal computer, embedded computer five class, more advanced computing machine has biocomputer, photonic computer, quantum computer etc.Computing machine be by hardware system and software systems dimerous.The hardware unit of traditional electrical brain system generally can be divided into input block, output unit, ALU, control module and mnemon, and wherein ALU and control module are collectively referred to as CPU (central processing unit).Along with the fast development of computer technology and network, computing machine is made to have become people's indispensable instrument in work, studying and living, equally also bring the potential safety hazard of subscriber computer information, the network information is stolen, information attack, virus are propagated etc. exists all the time and occurs.And existing network security controller of computer is inconvenient in use, and cannot good heat radiation cause components and parts to be burned, use inconvenience and be not easy to switch.
Existing network security controller of computer is not easy to realize switching fast, and the security of hard disk internal information is not high, and operation easy to use is all inconvenient easy, and serviceable life is not long.So patent name is: network security controller of computer, the patent No. be 2014206632180 patent propose concrete solution, the technical scheme of this patent is roughly as shown in Figure 1.
But it is exactly sometimes relay coil energising that this technical scheme exists a problem, due to the failure problems of relay, the normally closed switch of relay cannot effectively disconnect, at this time when use first hard disk, network connects, so very dangerous in fact.
Utility model content
The purpose of this utility model is to solve technical matters set forth above.
In order to realize above object, the technical solution of the utility model is as follows: a kind of computer network data safety governor, comprises change-over circuit plate, radiator fan, temperature sensor, power configuration device, change-over switch, knife switch, detection pilot lamp one, detects pilot lamp two, connector, the first hard disk, the second hard disk, network interface card; Radiator fan and temperature sensor are set above change-over circuit plate; The power end of change-over circuit plate connects power configuration device; The output terminal of change-over circuit plate is connected with 1 pin of change-over switch and one end of knife switch respectively; 3 pin of change-over switch are connected with 2 pin of connector, 2 pin of change-over switch are connected with the one end detecting pilot lamp one, detect the other end of pilot lamp one to be connected with 1 pin of connector, the other end of knife switch is connected with the one end detecting pilot lamp two, detect the other end of pilot lamp two to be connected with 3 pin of connector, 1 pin of connector, 2 pin, 3 pin are connected with the first hard disk, the second hard disk, network interface card respectively; The plug-in strip of change-over switch is connected by insulating cord with knife switch.
Compared with prior art, the beneficial effects of the utility model: guarantee that when use first hard disk network interface card branch road must be disconnect, effectively ensure that the security of data in hard disk.
Accompanying drawing explanation
Fig. 1 is principle block diagram of the present utility model.
Wherein, 3 is change-over circuit plates; 4 is radiator fans; 5 is temperature sensors; 6 is power configuration devices; 7 is detect pilot lamp one; 8 is detect pilot lamp two; 9 is change-over switches; 10 is connectors; 11 is knife switches; A is the first hard disk; B is the second hard disk; C is network interface card.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of computer network data safety governor, comprises change-over circuit plate 3, radiator fan 4, temperature sensor 5, power configuration device 6, change-over switch 9, knife switch 11, detects pilot lamp 1, detects pilot lamp 28, connector 10, first hard disk, the second hard disk, network interface card; Radiator fan and temperature sensor are set above change-over circuit plate; The power end of change-over circuit plate connects power configuration device; The output terminal of change-over circuit plate is connected with 1 pin of change-over switch and one end of knife switch respectively; 3 pin of change-over switch are connected with 2 pin of connector, 2 pin of change-over switch are connected with the one end detecting pilot lamp one, detect the other end of pilot lamp one to be connected with 1 pin of connector, the other end of knife switch is connected with the one end detecting pilot lamp two, detect the other end of pilot lamp two to be connected with 3 pin of connector, 1 pin of connector, 2 pin, 3 pin are connected with the first hard disk, the second hard disk, network interface card respectively; The plug-in strip of change-over switch is connected by insulating cord with knife switch.
Principle of work of the present utility model: the plug-in strip of change-over switch is connected by insulating cord with knife switch, thus when guaranteeing that the plug-in strip of change-over switch is connected with 2 pin of change-over switch, insulating cord drives knife switch to disconnect, when the plug-in strip of change-over switch is connected with 3 pin of change-over switch, knife switch is closed, effectively prevent in prior art the phenomenon causing network interface card branch road not disconnect because the sensitivity of relay is not high when using relay and occurs.
