Experimental study of a mechatronic system applied for subsea science instruments

Due to the shortage of current research methods to observe oceans in long term, real time, an innovative mechatronic system by using coaxial cable to connect a terrestrial shore station and a subsea science platform that can provide abundant power and broad bandwidth communication for subsea instruments, are developing. In this paper, an overview of this system was presented in detail from terrestrial facility to subsea infrastructure. And specially focus on introduction of constructing the platform consisted of a high direct current voltage to low levels power conversion sub-system and a control sub-system. Validation of this system was carried out in water pool involved in three subsea in-situ application instruments.
