Design Of Low-power Multi-parameter And Deep Sea For Long-term Field Observing System

With the global land resource constraints and environmental deterioration, the world are turning to marine development. while developing Marine resources and marine economy, it also caused serious damage to the marine environment and resources. The current space and abundant marine resources, marine environmental degradation has become an important issue in the development of our country. Solving the problems of the marine environment and marine ecosystems, making marine disaster early warning, maritime transport and offshore operations, has become an urgent need for timely access to abundant marine environmental parameters.Mainly for the status that ocean-situ data acquisition system can not meet the real-time long inspection and monitoring of the marine environment, the paper designs and implements a deep based Msp430 low-power multi-parameter situ observing system which can capture the deep-situ marine environment sensor multiple parameters, can wireless pass deep-situ data via the use of acoustic communication technology and iridium satellite communications technology to a remote client, and it is stable, easy to use, safe and a reliable data in-situ observation system.Low-power multi-parameter deep-situ observation system in this context completes the task which includes ocean observation data collection, transmission, save and sending, to realize online real-time remote and monitor the dynamic changes in situ deep sea marine environment parameters and to achieve real and efficient marine environmental monitoring and early warning purposes. This paper will make the following part of the work and the main research topic in detail:Firstly, give the analysis of the background and significance of the deep-situ multi-parameter Observing System Research and the status quo and development trends at home and abroad. Make a simple introduction about the subject related to the relevant principle of information which mainly includes deep-situ observation system data collection platform, universal serial communication interface technology, acoustic communications, Iridium communications, the theory of the sensor.Then dicuss the system hardware design. Mainly describe the hardware design of functional modules in detail. Including the design of underwater data acquisition system Data logger module and the use of buoy platforms Iridium module SBD9522 B. Discuss the System software design,mainly introduce the underwater acquisition system software design, including features of MSP430 initialization and configuration, serial port transceiver events, timers, RTC clock design and functions of ADC analog acquisition of implementation, and configuration-related user communication protocols and low-power design considerations.Finally, Debugging phase is mainly composed by three parts. That is commissioning inLaboratory, Joint commissioning machine in the Second Institute of Oceanography of State Oceanic Administration and Sea trial scene twice in South China Sea.
