Submarine Cable Route Tracking System Design And Realization

With the development of economic and the transformation of national defence position, The importance of submarine optical cable communication systems in communication between coastland and islands is emphasizing. A special equipment to direct ROV to submarine cable is absolutely necessarily in the process of submarine cable system construction or maintenance. This item is root in PLA NAVY's requirement of special equipment used in the process of construction or maintenance. for submarine cable system.. A submarine cable route tracking system basing on double three-dimensional magnetism sensor is designed in this thesis.The thesis firstly discusses the necessity of submarine cable route tracking system, and then studies both domestic and overseas current situation of submarine cable route tracking system'application. After analyzing the function of submarine cable route tracking system ,thesis bring up the solution which based on double three-dimensional magnetism sensor. Submarine cable route tracking in real time from using double three-dimensional magnetism sensor theory is particular expatiate. depending on this theory thesis founds the mathematical model for detecting submarine cable's distance and direction in real time. the system's construction is discussed. After the frame of signal disposal electrocircuit be depicted, the thesis designs the magnetism sensor's structure, shape and parameter which makes magnetism sensor can receive the electromagnetism signal in the space, describes the prepositive analog circuit, discusses the application of DSP in modern signal disposing. The thesis introduces the feature of TMS320C5409 DSP and describes the design of digital signal disposing module which based on TMS320C5409 DSP. The thesis solves the problem of the signal stability communication from submarine electron box. A dependable power management module and interface software are signed in this thesis. ths thesis expect the development of submarine cable route tracking system and the research in the future.The sign of submarine cable route tracking system solves the problem of submarine cable system construction or maintenance.
