The method for isolating and transmitting data between internal and external networks based on two-dimensional code image recognition technology according to claim 7, wherein the 2) capturing two-dimensional code: after focusing, the camera scans the intranet display once every 100 milliseconds to obtain the two-dimensional code displayed on the intranet display.
9. The method for isolating and transmitting the data of the internal and external networks based on the two-dimension code image recognition technology according to claim 1, wherein the state synchronization process in the internal network data extraction program is characterized in that a high-security camera of the internal network scans the two-dimension code of the external network, after the scanning is successful, the synchronization state of the data is analyzed, the data circulation task is notified of the synchronization state, when the data synchronization state is successful in warehousing, the incremental data is acquired again, when the data state is failed in warehousing, the two-dimension code is refreshed again, and the data synchronization is continued for the data record.
