The Design And Realization Of The Drilling Machine For Drilling The Sample Of Medium-Deep Core's Monitoring System

Since the 1960s, human need more and more mineral resources and energy. People focus their eyes on the ocean and obtain from the large-scale wealth from the marine. With the progress of science and technology, people improve their knowledge of marine resources; Ocean engineering technology comes a long way; Ocean exploitation step into new period. In recent years, a series of Marine high-tech technologies have developed, such as sea water desalination technology, deep-sea exploration technology, ocean drilling technology, remote sensing technique of oceanography, marine navigation technology and so on. Sampling technique of deep-sea drilling machine was introduced in this paper; it belongs to field of deep-sea exploration technology and ocean drilling technology. Deep-sea exploration technology plays an important role in the investigation and utilization of marine ecology, abyssal mineral mining and research on deep geological structure.The technical level of domestic sampling detection technology has a big gap compared to overseas. Exploration technology off shore is a mature technology, but prospecting apparatuses in the deep sea are few. Since developing the machine drilling shallow stratum core sample in deep sea successfully, this has filled the gap in china. So, sampling technique is updated and improved urgently. In view of actual requirement of remote intellective monitoring in the deep-sea drilling machine, this paper introduces an electronic monitoring system for the machine drilling the Sample of Medium-Deep Core in deep sea. The system applies distributed control. Host computer monitors and controls the underwater devices how to operator. Underwater measurement and control system executes command from host computer, collects data from various sensors and control the drilling machine. Underwater control system connects to the host computer with thousands of meters sheathed cable.Above all, this article proposes the system solution based on t the design and realization of the Drilling Machine for Monitoring System. And then the paper introduced the design principle of hardware system. It contains power monitor systems, OSD on screen display, data transmission interface and underwater measurement and control system. The software of the system is framed and designed in the forth chapter. The system software design includes MCU control program, the deck monitoring software system. Finally the paper describes the power supply mode and how to monitor the electric parameters of the whole monitoring system.This thesis also raises a scheme in laboratory, analyzes and compares the parameters between laboratory and the marine environment at the scene, and then continuously improves and obtains the ultimate success. The whole system is stable and reliable. The machine drilling the Sample of Medium-Deep Core in deep sea has broad application prospects and development of space in aspect of deep-sea exploration, acquisition of mineral samples and detection of marine geological structure. Its'electronic monitoring system has generality and could be used for many situations. This set of equipment for ocean drilling in our country will provide a powerful tool; also provide first-hand data for Chinese scientists researching on deep-sea mineral samples.The system that is the first kind of Deep-sea monitoring system based on thousands of meters sheathed cable, which is developed firstly in China. In May 2009, we hold the Drill sampling experiment in the South China Sea. In October 2009, we also do the same experiment again in Eastern Pacific and took some core samples successfully. the development effort was achieved complete success.
