Embodiment 1
[0030] like figure 1 As shown, the embodiment of the present invention provides a data isolation transmission system, including: a control terminal, an internal controller, an internal data dock, an external data dock, an external sending terminal, a relay, and an electronic disk. The internal controller and the The internal data docks are all connected to the control terminal, the internal controller is connected to the coil of the relay, the normally open contact of the relay is connected to the internal data dock, and the normally closed contact of the relay is connected to the internal data dock. It is connected with the external data dock, the common contact of the relay is connected with the electronic disk, and the external data dock is connected with the data of the external sending end;
[0031] The internal controller is used to control the relay;
[0032] When the common contact of the relay leaves the normally closed contact, the electronic board will be powered d...
Embodiment 2
[0049] An embodiment of the present invention provides a data isolation transmission method, using the data isolation transmission system described in Embodiment 1, including the following steps:
[0050] S1, the control terminal receives the data sent by the intranet sending computer;
[0051] S2. After receiving the data, the control terminal sends a data transmission instruction to the internal controller, and at the same time, the control terminal sends data to the internal data dock;
[0052] S3. After the internal controller receives the instruction, it controls the common contact of the relay to be connected to the normally open contact, so as to realize the connection between the electronic disk and the internal data dock, and the common contact of the relay is separated from the normally closed contact. point, the electronic disk is powered down to clear data;
[0053] S4, the internal data dock transmits data to the electronic disk;
[0054] S5, after the electroni...

Abstract
The invention discloses a data isolation transmission system and method, and relates to the technical field of information security. The system comprises a control terminal, an inner terminal controller, an inner data dock, an outer data dock, an outgoing terminal, a relay and an electronic disc, wherein the electronic disc is connected with an inner network or an outer network through the replay arranged between the inner network and the outer network; further the unidirectional transmission of data from the inner network to the outer network is realized by using the electronic disc as a medium. The system can realize data automatic transmission through logic control, does not need manual intervention, is low in cost and high in efficiency, is not required to be connected through a reticle or other types of connecting lines, avoids the problem of outer network intrusion caused by connecting lines, and guarantees the security of inner network information, thereby meeting the security of inner network information of industries, such as governments, armies and energy.
Description
technical field [0001] The invention relates to the technical field of information security, in particular to a data isolation transmission system and method. Background technique [0002] At present, in daily office work, most of the data files are imported from the internal network to the external network by means of burning CDs or burning with the computer's own recorder to ensure the security of intranet information. However, the method of CD burning is low in efficiency and high in cost; the way of burning with the computer's own recorder cannot complete the burning of a large number of multi-task data files, and there are many manual interventions. [0003] In addition, there are still some companies that use software to achieve one-way data transmission. This method needs to be connected through a network cable or other types of connection lines. It is easy to be invaded by the external network, and there are great hidden dangers in the security of internal network in...
