Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
Seeing Fig. 1, a kind of hardware platform realizing underwater sound communication, including controlling module, D/A digital to analog converter, power amplifier, the first transducer, A/D analog-digital converter, programmable amplifier, band filter, the second transducer, preamplifier, voltage comparator；Described control module, D/A digital to analog converter, power amplifier, the first transducer are sequentially connected with；Described the second transducer, band filter, programmable amplifier, A/D analog-digital converter, control module and be sequentially connected with；Preamplifier and voltage comparator also it is connected with in turn between the second described transducer and control module.
Described control module is connected with memorizer.
Described control module includes the arm processor and the FPGA that are sequentially connected with；Described FPGA is connected with D/A digital to analog converter and A/D analog-digital converter respectively；Described arm processor is connected with memorizer and voltage comparator respectively.
Described arm processor adopts ARM9 chip S3C2440 type.
Described FPGA adopts the forth generation low-power consumption FPGA EP4CE22F17 of A Erte company.
At transmitting terminal, arm processor is sent data to by serial ports and carries out respective handling in FPGA.D/A digital to analog converter is connected with FPGA, signal after processing is carried out digital-to-analogue conversion, D/A digital-to-analogue connects power amplifier, analogue signal is after power amplification, passing to the first transducer being connected with power amplifier, the signal of telecommunication enters transmission in underwater acoustic channel after being converted to acoustical signal via the first transducer.
At receiving terminal, via the acoustical signal after dissemination channel, pass to band filter after first being transferred to the signal of telecommunication by the second transducer when receiving, other band noise of elimination.Band filter connects programming amplifying module, and signal is carried out programme-controlled gain amplification, and gain amplifier is controlled in real time by FPGA, guarantees that processing signal is in optimum range value, to improve communication quality.Programmable amplifier connects A/D analog-digital converter, and A/D analog-digital converter connects FPGA.Signal after programming amplifying is via after analog digital conversion, FPGA reading in and carry out respective handling.Data after process are passed to arm processor by serial ports and are namely completed communication process by FPGA.
For pilot tone function, pilot signal first carries out preposition amplification after the second transducer receives, and preamplifier is followed by voltage comparator, and voltage comparator connects arm processor.Voltage comparator passes to arm processor after amplified signal is carried out respective handling, carries out frequency judgement, whether determines the work of FPGA.It is greatly saved system power dissipation.
