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...
