Data exchange device between internal network and external network

Abstract

The invention provides a data exchange device between an internal network and an external network, comprising an input terminal, a ferry device and an output terminal, wherein the ferry device comprises an intermediate server, a transfer server, a record optical drive, a read-only optical drive, an intermediate manipulator, a transfer manipulator, a first disc warehouse, a second disc warehouse, athird disc warehouse, and a controller; the output terminal comprises an output manipulator, an output record optical drive, a fourth optical disc warehouse, an output controller, and an output disctray; the input terminal comprises an input manipulator, an input disc tray, an input read-only optical drive, an input controller, and a fifth disc warehouse; the input terminal and the intermediateserver are connected by a network cable, the relay server is connected to the internal network for data transmission, the internal network is connected to the output terminal for data transmission, and the intermediate server is provided with a virus killing module. The invention enables a real "physical isolation" between the external network and the internal network.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a data exchange device between internal and external networks. Background technique [0002] The inter-network data exchange system is developed to meet the needs of secret-related intranet and extranet file exchange. At present, the data exchange operations of secret-related internal and external networks are becoming more and more frequent, but the information ferrymen will touch all kinds of information physical CDs, and there is a high risk of leakage, and the existing method of manually ferrying and burning disks is inefficient and error-prone, which can no longer meet the requirements Work requires an urgent need for a fully automatic inter-network switching solution. Through automation, the computer command controls the manipulator to carry out the ferrying and burning work of the file exchange disk, and improves the transfer efficiency.
