The Integrate System Design For The Acquisition Of Deep-Sea Transducer Signal

Putting the transducer and it's integrate system into deep sea directly to detect deep-sea environment, because of it's field test and cheap cost, short work terms, has been an important method on the research of deep sea.According to researches of similar work in the world and the subject's task, we have made an integrate system with one temperature and three chemical transducer. These transducer transduce deep-sea's temperature and chemical parameter into voltage. The A/D module in the digital system will converse the analog voltage signal into digital signal, which will be saved in the system's memory and received by PC computer. The dissertation is divided into introduction, theoretic modeling and key technic, system realization, system experiment, summarization and expectation.In introduction, we explain the important meanings on the research of deep-sea resource and the relationships between it and transducer integrate system. We also analyze the advancement on the research in transducer and it's integrate system in the world. At the end of this part the research's source, meaning and feasibility are brought out.The theoretic modeling provide the feasibility in transducer's selection and their measurement model. This part mainly analyze the temperature and chemical transducer's unique character and based on which we design the corresponding measurement method.System realization is divided into hardware and software. We design hardware according to the require of deep-sea transducer integrated system's high sensitive, self-storage and low power principle. The software's design are based on the modularization thinking. And the important hardware and software modules are also been explained in detail.The experiment part are make up of system integrate method, lab experiment and ocean experiment. We mainly explain ocean experiment's method and draw the track according to the transducer's signal data.At the end of dissertation,it is summed up the work and brought up the deeper research aim.
