Research On The Data Acquisition Controller Of The Automatic Multi-function Energy Conserving Marine Environment Monitoring System

It is certain useful to obtain multi-parameter profiler for a long term in ocean research and Engineering application. Mooring buoys and submersible buoys are one of the most widely used ocean monitoring platforms, mainly used for fixed-point monitoring of the marine environment. Ocean buoys play an important role in the study of the interaction among oceans, atmosphere and global climate changes, forecast global and regional marine disasters, marine pollution monitoring, satellite remote sensing data authenticity check, and as a platform for communications and underwater acoustic positioning. The automatic anti-collision and security of the buoys are poor, however. Due to the main floating body is installed under water 50-100 meters, the submersible buoys have good security. It is widely applied in the marine three-dimensional monitoring system. Because it always hides in the sea, the type of the measurement sensors is limited, real-time data transmission is difficult, the application of the submersible buoys is affected in some extent.The autonomy multi-function energy conserving ocean elements acquisition system combines with measurement techniques both buoy and submersible buoy. This profiler is based on a taut fixed-point mid-water mooring system.It incorporates a small, instrumented vertically profiling float attached via an electromechanical cable to a winch integral with the main submersible buoy and has the function of automatic anti-collision. There is a simple energy conserving transmission and storage device in the submersible buoy. A low power, highly reliable data acquisition and control system is designed. In this design,the SOC C8051F340 is used as the host controller. Hardware and software of the profiler are designed.The profiler not only be able to measure and transmit the surface hydrological parameters, but also can acquire the ocean elements as deep as 50 meters under water for profiling measurement relying on a single sensor. SD Memory Card is applied to the ocean elements storage system.This new instrument platform establishes the foundation of marine measuring instruments to be controlled intelligently and underpins human ability to make sustained in situ observation of the ocean.
