Description

Split type no-feedback one-way data transmission set

Technical field

This utility model is related to data communications equipment, can improve interior more particularly, to one kind while transmission speed is ensured Outer net arranges the split type no-feedback one-way data transmission set of distance.

Background technology

Unilateral Data Transferring System is generally used for Low Security Level network to High Security Level network transmission file or data, or is used for Non- classified network is to classified network transmission data.The equipment for realizing now one-way data transfer is essentially all all-in-one, all-in-one The relevant device (computer, router, hub or gateway) of one termination Low Security Level network, the phase of another termination High Security Level network Pass equipment (computer, router, hub or gateway), one-way transmission are realized in device interior with quarantine measures.Using one The advantage of machine is equipment working stability, and equipment is placed on machine room, and safety is relatively preferable, but because has following several shortcomings, application Occasion is restricted, specific as follows：(1) Low Security Level network can not farther out, if all-in-one with the physical distance of High Security Level network Using network interface, the then because transmission range of general networking is less than 100 meters (otherwise transmission speed will be affected), two No more than 200 meters of physical distance between individual network, if using USB interface, no more than 10 meters of transmission range, if Using SATA interface, transmission range is no more than 5 meters；(2) data one-way transmission is not directly perceived, have impact on the motility of interface.One Body machine linkup transmit end computer typically adopts three below interface with receiving end computer：Network interface, USB connect and connect with SATA Mouthful, USB interface agreement corresponding with SATA interface is all full-duplex protocol, that is, order can all have transmission with receive, data Also have transmission and receive.Because such product can't pass the Black-box Testing of national secrecy department, network is only used Interface simultaneously (is only sent, do not receive) using udp protocol；Because the transmitting terminal computer of Low Security Level network has typically had now One network interface card, if so use network interface, also a network interface card will be installed with receiving end computer to transmitting terminal computer again, So that system in-convenience in use；(3) data speed can not be effectively improved, if using network interface, because using udp protocol, Then in order to ensure the correctness of data, it is necessary to by same data is activation repeatedly reducing error probability, if sending three times, use The actual data transfer rate that PCI-Express can reach only has 333Mbps.

Utility model content

To solve the above problems, the purpose of this utility model is to provide one kind to improve while transmission speed is ensured Intranet and extranet arrange the split type no-feedback one-way data transmission set of distance.

This utility model realizes that by following technical measures a kind of split type no-feedback one-way data transmission set is wrapped The data transmitting equipment and data receiver for being separated from each other placement is included, the data transmitting equipment is with data receiver by extremely Few optical fiber connection；The data transmitting equipment includes the communication module for being connected to outer web network equipment, connection communication module FPGA data processing module, connect FPGA data processing module at least one optical fiber sending module, and power supply electricity Road；The data receiver includes the communication module for being connected to inner-mesh network equipment, at the FPGA data of connection communication interface Reason module, connects at least one optic fiber transceiver module of FPGA data processing module, and power control circuit.

Used as a kind of optimal way, the communication module in the data receiver contains height with FPGA data processing module Speed caching, reduces the loss of data risk for being produced because of Intranet receiving data more slowly by multi-level buffer mechanism.

As a kind of optimal way, in the data receiver, there is an alarm module.

Used as a kind of optimal way, the warning circuit is sound light alarming circuit.

Used as a kind of optimal way, the communication module interface is USB interface, network interface or SATA interface.

Data transmitting equipment of the present utility model and data receiver are discretely located, data transmitting equipment and data receiver Equipment is connected by least one optical fiber, for data are sent from Low Security Level network to High Security Level network.This device is due to by light Fine connection, is no longer limited by physical distance between Low Security Level network and High Security Level network, because can transmit in theory of fiber Several kilometers even more than ten kilometers, distance is no longer problem；Data one-way transmission of the present utility model is very directly perceived, easily by correlation The Black-box Testing of secret unit, is connected by one-way optical fiber between two equipment, and data one-way transmission is very clear；This utility model More flexible with the interface of receiving end computer with transmitting terminal computer, transmission equipment can be placed near transmitting terminal computer, because And multiple interfaces mode such as USB can be taken, and LAN or SATA interface, in the same manner, receiving device also may be used with receiving end computer To take multiple interfaces mode；Data transmission bauds of the present utility model is greatly improved because send equipment and receiving device it Between be one-way transmission, so send, include the agreement of feedback ICP/IP protocol, so enables speed be greatly improved.
