Research And Realize The Electronic System Of Deep-sea Hydrothermal Detection

Deep-sea hydrothermal vents are windows of lithosphere and ocean laps about energy and material exchange. Scientists learn marine related physical and chemical quantity parameters through this window. As basic parameters of marine hydrothermal vents, the temperature, depth and salinity plays a very important role to understand and analysis of deep-sea hydrothermal if they can be measured accurately.Deep-sea hydrothermal column detection system mainly consists of underwater unit and deck unit. Power supply and information transmission are completed by the energy and information hybrid transmission unit. Underwater embedded measurement and control unit is the key part to realize the whole system function. This paper puts the cricuts design of the temperature sensor, depth sensor, salinity sensor, which are the parts of underwater embedded measurement and control unit, as the keys. And then the temperature, deep, salt sensors are integrated into the existing system, thus forming a complete the deep-sea hydrothermal detection system.This paper mainly divided into several parts:1. Firstly this paper introduces the overview of deep-sea hydrothermal of detecting technology, and then paper summarized CTD detection technology at home and abroad, the research present situation and development trend.2. The second part is Aiming at the whole system analysis and design. Firstly this paper describes the overall system frame structure, operating platform and development environment, and then expounds various temperature, depth and salinity (CTD) measuring the basic working principles respectively. Then paper introduces the basic foundation of sensor selection and sensor error analysis and correction methods. At last, every part of the circuit functions are briefly described and analyzed.3. In the third part, the paper mainly describes the deep-sea hydrothermal detection electronic system hardware design. System developing platform is based on MSP430 low-power processor. Paper implement circuit modular design of high precision data acquisition circuit, signal processor and peripheral circuit, the power supply, and give the circuit design requiring attention items and hardware circuit design experience.4. The fourth part introduces software components, including embed system software and PC software, of hydrothermal detection system. The functional modules specific implementation details are given after describing the system software processes.5. Finally, according to the test results of the experiments, this paper draws some conclusions. Experiments verify the hydrothermal detection electronic system is basically meeting the subject of the indicators required and the design target. At last the paper makes a summary of the whole working and points out the place that can be further improved and then foresees the application prospect of the hydrothermal detection electronic system.
