In the utility model, the main functions of the safety switching device are as follows: a safety switching mechanism is additionally arranged in the common double-computer switching, so that the information theft of the external device for the machine hosts during the double-computer switching and the information leakage caused by the double-computer interaction are avoided, and the safety of the double-computer switching is guaranteed more completely.
Description
Technical field
The utility model relates to computing machine two-shipper safety switching apparatus, and definite saying so discloses a kind of computing machine two-shipper safety switching apparatus, mainly is that the safety that has disclosed between the two-shipper is switched structure, belongs to field of computer technology.
Background technology
Conventional computing machine two-shipper is isolated switching and can be adopted KVM to connect two main frames, two main frames are joined a cover external unit mouse, keyboard and display, wherein KVM is responsible for connecting peripherals, be mouse, keyboard and display, the information via that KVM equipment will receive from mouse-keyboard judges that arbitrary of decision back and two main frames is connected, make two shared same set of mouses of main frame, keyboard, display, the joint operation of having saved the space and having strengthened two-shipper.But using KVM to switch in the whole process of two-shipper, the information security that information interaction causes always is unheeded content, the mouse of KVM equipment especially now, keyboard interface and prior USB storage device interface have interlinking, therefore traditional KVM can not avoid malice to use USB to steal data and use the keyboard of band memory device, the risk that mouse is stolen data, also there is possible information interaction risk in two-shipper in handoff procedure simultaneously, therefore guarantees that the two-shipper information security is the eager technical issues that need to address.
The utility model provides a kind of two-shipper safety switching apparatus, task is to avoid the active computer two-shipper to isolate in the handoff technique information interaction that may exist between information interaction that may exist between the two-shipper of realizing switching by KVM and two-shipper and mouse, the keyboard.
The utility model content
Technical problem to be solved in the utility model provides a kind of safe two-shipper switching device shifter, make two-shipper when switching, avoid information interaction and avoid two-shipper and the information flow of external unit when mutual, guarantee that the two-shipper that switches does not have information interaction, the information security of each main frame in handoff procedure.
What the utility model was described is a kind of two-shipper safety switching apparatus, it comprises two main frames, safe handover module, power module and external unit is characterized in that safe handover module mainly is divided into information receiving module, information Control module, message processing module three big modules; Wherein, information receiving module connects mouse, the keyboard in the peripherals; The information Control module adopts optical fiber cable to be connected with the reception information module, and adopt optical switching device as the central control unit in the information transmission control module, the other end of photoswitch information transmission control module is connected with two identical message processing modules, and the other end of two message processing modules is connected with a main frame respectively.The utility model is finished through the following steps: peripherals mouse, keyboard are connected with the reception information module, and the other end that receives information module connects optical fiber cable mouse, the keypad information that receives spread out of; Optical fiber cable one-way transmission mouse, keypad information are given the information transmission control module; The information Control module is central control unit with the photoswitch, mainly be selectively to be connected by photoswitch by the information that optical fiber cable transmits from receiving information module with arbitrary message processing module, message processing module is handled the information that transmits from the information Control module and the information that transmits by direct connection from the peripherals display and being connected with main frame by circuit when making this two parts information of same, at this moment, peripheral hardware mouse, keyboard and display are connected with main frame, make main frame normally to use.
The utility model is when using, peripherals mouse, keyboard connect the information receiving module in the safe handover module, the information that information receiving module receives is given the information Control module of safe handover module by the optical fiber cable one-way transmission, the one-way transmission of optical fiber cable make outer be located at the USB memory device of use and mouse, keyboard same-interface or have the mouse of memory function, when keyboard malice is stolen user rs host information, can not reach the function of transmitted in both directions, therefore can not steal any information from main frame, guarantee the safety of peripheral hardware end host information; The information Control module mainly by photoswitch as central control unit, the input end of photoswitch is made of two parts, a part is connected with optical fiber cable, receive the peripheral hardware mouse, keypad information, another part, connect the peripherals display, the other end of photoswitch is expanded into the not output terminal of gating simultaneously of two-way, its output terminal respectively connects a message processing module, this two information modules are gating simultaneously not under the control of photoswitch, message processing module will be handled from the information via that the information transmission control module receives and directly be connected with a main frame, because two not existence of the message processing module of gating simultaneously, therefore avoid two shared same message processing modules of main frame, therefore fundamentally disconnected two main frames, made two main frames not have to produce the possibility of information interaction.
Good effect of the present utility model is: switch mutually in the process of use at two main frames, the common switching two-shipper of original KVM mode can not guarantee the peripherals mouse, keyboards etc. are not stolen and avoid two main frames issuable information interaction in handoff procedure host information, the utility model adopts optical fiber cable and the information Control of separating is handled the unit structure mode and made two main frames avoid the information of peripheral hardware to steal and two main frames mutual in handoff procedure fully, makes two main frames reach being perfectly safe of each main frame internal information in use.Especially in the network layout environment that uses in-house network and extranets, guaranteed that especially the information of in-house network is not stolen.
Description of drawings
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
Be described further the utility model below in conjunction with accompanying drawing:
In Fig. 1, K represents keyboard (Keyboard), and V represents display (Video), and M represents mouse (Mouse), U1 representative information receiver module, U2 representative information control module, U3 representative information processing module; Wherein, be connected by optical fiber cable between U1 information receiving module and the U2 information Control module, guaranteed the one-way transmission of information, avoid keyboard and mouse interface to insert illegal memory device from main frame conduct retrograde information, U2 information Control module mainly is to be connected with one of them message processing module U3 as central control unit control U1 information receiving module with photoswitch, wherein U2 also connects display V equipment simultaneously, photoswitch is controlled display V simultaneously and is connected with one of them message processing module U3, in this process, U1 equipment and V equipment have consistance, and unite switching by information control apparatus simultaneously; Message processing module U3 one end link information control module U2, the other end connects arbitrary main process equipment PCA or PCB, because the existence of information Control module U2, the information interaction of having avoided PCA and PCB to exist, therefore can guarantee that in handoff procedure PCA and the PCB information security of main frame separately are not stolen.
