One-way data acquisition equipment and system based on air isolation

The invention discloses one-way data acquisition equipment and system based on air isolation. The one-way data acquisition equipment comprises data acquisition hardware equipment and a data acquisition software system, wherein the data acquisition hardware equipment comprises a data acquisition server, a graphic encoder, a high-definition recognizer, a data storage server and a data storage library, and the data acquisition software system comprises a data sending unit and a data receiving unit. The beneficial effects of the invention are that: the lattice code identification cameras of the first security domain sending unit and the second security domain completely eradicate the condition that isolation equipment, network equipment and lines exist between the two security domains physically. The method completely eradicates external invasion by using network connection of a security domain, integrates technical means such as dynamic encryption and decryption and dynamic identity recognition and authenticatio
