Problems solved by technology

[0005] According to the embodiment of the present invention, a mechanical NOT gate physical isolation data one-way transmission system and method is provided, through the logical control of the mechanical action of the ferry terminal, the data transmission between the two physically isolated networks is solved manually. Due to the defects of time-consuming and labor-intensive operation, low efficiency, frequent operation by personnel and low reliability, the automatic operation of each component is realized without manual intervention, saving manpower

Embodiment 1

[0034] Refer below figure 1 and figure 2 A one-way transmission system for physical isolation of mechanical NOT gates in this embodiment is described, including: a sending end 200, a ferry end 300, a receiving end 400, and an isolation device.

[0035] The sending end 200 receives the electrical signal sent by the first network device, converts the electrical signal into an optical signal through the electro-optical conversion module, and then transfers the luminous signal to the ferry end 300 by the transmitter;

[0036]The ferry end 300 receives the optical signal sent by the sending end 200, converts the optical signal into an electrical signal through the electro-optical conversion module, controls the opening and closing of the isolation device, and then converts the electrical signal into an optical signal through the electro-optical conversion module and sends it to the receiving end 400 rpm luminous signal;

[0037] The receiving end 400 receives the optical signal ...

Embodiment 2

[0051] This embodiment provides a method for one-way transmission of physically isolated data using the mechanical NOT gate of the system of Embodiment 1, such as image 3 shown, including the following steps:

[0052] S1. The first network device sends a data transmission application to the sender 210. After the sender 210 accepts the application and feeds back the feedback information of accepting the application to the first network device, the first network device sends the data to the sender 210.

[0053] S2, the first optical gate 110 is normally open, and correspondingly the second optical gate 120 is closed, and the optical channel between the transmitter 210 and the ferry device 310 is connected; the transmitter 210 transmits data to the ferry device 310 .

[0054] In this embodiment, if the optical channel between the transmitter 210 and the ferry device 310 fails to communicate successfully, it can be judged that the first optical door 110 is in the closed state, wh...

Abstract

The embodiment of the invention provides a mechanical NOT gate physical isolation data one-way transmission system and method. The system includes a sending end, a ferry end, a receiving end and an isolation device, wherein the sending end receives data sent by first network equipment and then transmits the data to the ferry end; after the transmitting end completes data transmission, the ferry end controls the first light door to be closed, meanwhile, the second light door is opened, and a one-way light channel between the ferry equipment and the receiver is automatically communicated; the ferry end transmits data to the receiving end; after the ferry end completes data transmission, the second light door is controlled to be closed, and meanwhile, the first light door is opened; and the receiving end sends the received data to a second network device. Mechanical NOT gate physical isolation of the intranet and the extranet can be achieved, safety of high-safety industry intranet information is guaranteed, all parts are operated automatically, manual intervention is not needed, and manpower is saved.

Description

technical field [0001] Embodiments of the present invention generally relate to the technical field of information transmission, and more specifically, relate to a system and method for one-way transmission of data physically isolated by a mechanical NOT gate. Background technique [0002] The rapid development of information communication technology and Internet technology has changed our life and work style and improved our work efficiency, but it has also brought many security problems, such as network information leakage, viruses and so on. These problems seriously threaten the information security of various enterprises and institutions. However, traditional information security protection technology only detects and controls data transmission at the software level, which cannot meet the requirements for physical isolation between classified networks and external unsafe networks. [0003] Physical isolation means that the internal network must not be directly or indire...
