The cross-sea surface communication network mainly realizes communication between unmanned ships on the water surface, including on-water, under-water and cross-sea surface hybrid communication among ships, so as to realize horizontal connection of multiple unmanned systems on the sea surface.
The communication between ships connected into the distributed anchor chain system can use radio signals to communicate on the sea surface, and underwater communication among a plurality of unmanned ships can be completed by utilizing the underwater sound communication module, so that underwater communication networking of the unmanned ships is realized.
The cross-sea surface communication network mainly realizes the two-way transmission of cross-medium information, a transduction module in a ship anchor chain system converts communication information of different transmission forms of cross sea surfaces, decodes and encodes an over-water radio signal and an under-water underwater sound signal through the transduction module, performs communication between an air-sea surface and cross sea surface and under water, and enables cross-domain nodes in all vertical directions to be connected, thereby realizing the vertical connection of the multi-unmanned system at sea.
In particular, the transduction module typically decodes and encodes using the following steps:
Receiving a signal: first, the transduction module receives a communication signal from the air, sea surface or underwater. These signals may be underwater acoustic signals or radio signals from the surface.
And (3) signal demodulation: the received signal needs to be demodulated and converted to a digital signal or an analog signal suitable for further processing. This process typically involves the modem demodulating the signal to recover the original data.
And (3) decoding data: the demodulated signal needs to be decoded to convert the information carried therein into a readable data format. For digital signals, a decryption process may be involved to recover the original information.
Signal coding: the transduction module may need to re-encode the data before transmitting the information to the target device. This process may include encryption to secure communications or compression of data to reduce transmission bandwidth.
And (3) signal modulation: finally, the encoded data needs to be modulated to accommodate the transmission environment under water or on the surface. This may include converting the digital signal to a suitable analog signal and adjusting the frequency of the signal to accommodate, for example, underwater sound or radio transmissions, depending on the characteristics of the communication medium.
The underwater communication network consists of a plurality of underwater unmanned ships and a submarine underwater acoustic anchor chain communication network; communication between the underwater unmanned system and the unmanned ship carrying the distributed anchor chain system is mainly realized.
