The invention relates to the technical field of communication, and discloses a cross-domain adaptive cooperative
system based on a
data link, which comprises a physical
adaptation layer, a protocol
abstraction layer, an intelligent scheduling layer and a
security enhancement layer, the physical
adaptation layer is used for receiving and transmitting cross-domain equipment signals, realizing
software radio dynamic waveform reconstruction of
multiple frequency bands, generating digital
baseband signals and transmitting the digital
baseband signals to the protocol
abstraction layer; the protocol
abstraction layer is used for realizing grammar conversion of multiple protocols, generating a semantic
data stream in a unified format from the digital
baseband signal, and transmitting the semantic
data stream to the intelligent scheduling layer; the intelligence layer calculates the service priority according to the semantic data flow, realizes self-adaptive
broadband distribution and realizes data
packet scheduling; and the
security enhancement layer generates encrypted state
sensing data from the data packet, interacts with the
command and control system, and sends the encrypted state
sensing data to the physical channel. According to the technical scheme, the problem of
interoperation of heterogeneous systems can be solved, the spectrum efficiency is improved, and fine-grained
access control of
security domain transmission is realized.
