A New Idea for Moored Profiling System Based on Potential-energy-driven concept and method

摘要

Moored profile observation system can use a set of sensors to realize vertical reciprocating motion along the mooring line, so as to obtain real-time observation of marine environmental parameters. It is an effective method for vertical water observation in deep sea. When is proposed for reciprocating movement faster, longer distance (or more profile number), providing a more stable observation platform and other requirements, the current technology of the reciprocating observation will encounter a series of difficulties or bottlenecks. This paper analyzes the two reasons for this bottleneck or difficulty: 1. Because profile observation system integrates driving unit and observation unit, when driving unit is working, the vibration and electromagnetic radiation generated by motor in driving unit will affect some sensors' work; 2. The power-driven source comes from battery pack, when needed more batteries for higher aim, the increased batteries will bring system lots of negative influences. For these two reasons, this paper proposes a new design method of reciprocating profile observation system based on the potential-energy-driven, driving unit and observation unit separation, solves the technical difficulties encountered in improving requirements, a new prototype laboratory is testing the feasibility of this new idea.
