Secret-related file exchange system based on domestic operating system

The invention discloses a secret-related file exchange system based on a domestic operating system. The file exchange system comprises a cabinet body unit, the cabinet body unit comprises an operation control unit, a protocol conversion unit and peripheral modules, the operation control unit is in communication connection with the protocol conversion unit, and the protocol conversion unit is in communication connection with the peripheral module. A group of Socket long connections with the protocol conversion unit are asynchronously established and maintained in the operation control unit, the Socket long connections are in one-to-one correspondence with the peripheral modules, and the communication connection states between the operation control unit and the protocol conversion unit and between the protocol conversion unit and the peripheral modules are determined in a mode of sending heartbeat packets at regular time; the domestic operating system is used for replacing an original Windows operating system,
