Inter-network data bidirectional transmission method and device

Abstract

The invention provides an inter-network data bidirectional transmission method and device, and the method comprises the steps: monitoring whether a first network end has data to be transmitted to a second network end or data to be received or not, wherein the first network and the second network are physically isolated from each other; when it is monitored that to-be-sent first data exists in thefirst network end, determining whether the first data is sent or not according to the receiving and sending state of the first network end, and if yes, sending processing is carried out, and converting the first data into first two-dimensional code data; displaying a first two-dimensional code image corresponding to the first two-dimensional code data, so that the second network terminal scans thefirst two-dimensional code image; when it is monitored that the second two-dimensional code data to be received exist in the first network end, determining whether the second two-dimensional code data are received or not according to the receiving and sending state of the first network end, and if yes, conducting receiving processing. Through the scheme, bidirectional and real-time data transmission between different physically isolated networks can be realized.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a method and device for two-way data transmission between networks. Background technique [0002] By isolating the internal network (private network) and the external network (Internet), the network security of the internal network can be guaranteed. However, with the rapid development of the Internet, mobile Internet and even 5G technology, the gap between the internal network and the external network is becoming more and more The greater the need for a large amount of information exchange, the greater the contradiction between ensuring the integrity of the network and improving work efficiency. [0003] At present, data exchange between the internal and external networks is generally carried out through optical disc ferry, infrared one-way transmission and image ferry. However, mechanical failures often occur in the optical disc ferry system, and the real-time perfor...
