Design of the Power Supply System and the PHM Architecture for Unmanned Surface Vehicle

Unmanned Surface Vehicle (USV) has been widely used in the marine environment monitoring. The safety and reliability of the USV, especially the power supply systems, is very important. In this paper, a power supply system with PHM is proposed for USV, Field Programmable Gate Array (FPGA) is used as the main controller. Fault diagnosis, fault location and fault isolation can be implemented by acquiring the voltage and current information of all power equipment. At the same time, the fault prediction and health management of the whole ship is carried out by collecting the temperature, humidity, vibration and other information of every part of the USV. The power supply system and the Prognostics and Health Management (PHM) architecture proposed in this paper can be used for USV maintenance decision in the future.
