Local area network intercommunication method

Abstract

The invention discloses a local area network intercommunication method, and the method comprises the steps: employing a TMDS (Transition Minimized Differential Signaling) protocol of an HDMI, transmitting file information which is converted into an image format to a video collection card in the other local area network through the HDMI, obtaining a digital signal of an image through the video collection card, analyzing the image information into an original file through a data processing module, and obtaining the transmitted data. The method can achieve the intercommunication of two independent local area networks, provides a channel of information communication for two PCs at different network segments, does not employ the Internet for communication, and avoids the possibility of data leakage and PC invasion. The method employs the TMDS protocol for transmission of data, and improves the data transmission stability.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a local area network intercommunication method. Background technique [0002] With the development of the times, communication becomes more and more important. Most industries choose the Internet for communication. While the Internet brings convenience, it also brings problems such as information security. Therefore, for industries with high security requirements, the Internet will be avoided. However, as the industry is more closely connected, communication between each other is essential, and how to establish secure communication for two LANs that do not communicate is particularly important. [0003] Nowadays, the common Internet communication has the following disadvantages: when transmitting data on the Internet, it is easy for criminals to obtain information directly through some means; Internet communication security measures are not strict and easy to be invad...
