Embodiment Construction

[0026] Such as figure 1 , figure 2 As shown in the figure, an automatic transmission method of database table with safe physical isolation, synchronously copy and transmit the content of the network database data table located on network A to the network database data table located on network B, so as to realize the security isolation between network A and network B , which is characterized by the following steps:

[0027] 1) Get network database table data;

[0028] 2) According to the custom serial communication protocol specification, the obtained table data is repackaged and sent through the serial port;

[0029] 3) Receive the serial communication data packet, and re-analyze the obtained table data according to the custom serial communication protocol specification;

[0030] 4) Establish a database connection, and update the parsed data into the database table.

[0031] The step 1 establishes a connection with the data source database via the automatic collection mod...

Abstract

The invention discloses a safe physical-isolation automatic transmission method of network database tables, which can be used for synchronously copying and transmitting the content of a network database table on a network A into a network database table on a network B and safely isolating the network A from the network B. The automatic transmission method comprises the following steps of (1) obtaining network database table data; (2) according to customized serial port communication protocol specifications, repackaging the table data to send by a serial port; (3) receiving a serial port communication data package, and reanalyzing the obtained table data according to the customized serial port communication protocol specifications; and (4) creating database connection and updating the analyzed data into the database table. The automatic transmission method can be used for obtaining the data of database tables across networks, automatically synchronizing the data of the database tables of ethernet networks which are safely isolated from one another, achieving the aim of sharing data, realizing the safety and the sharing of the data as well as safe isolation, and ensuring information safety.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to an automatic transmission method of a safe and physically isolated network database table. Background technique [0002] Ethernet transmission technology and various databases are widely used today. The transmission of secure physical isolation of database data across the network is still blank. Unable to meet the technical development requirements of information sharing. Contents of the invention [0003] Aiming at the above-mentioned deficiencies existing in the prior art, the present invention provides a method for automatically transmitting network database tables that are safely and physically isolated; the present invention can realize cross-network database table data acquisition, and realize mutual safe isolation of Ethernet database table data. Automatic synchronization to achieve the purpose of data sharing, realizing data security and sharing; realizing ...
