Abstract
In order to solve the problems of environmental pollution, poor safety and poor working reliability in the hydraulic system of wave power device, a hydraulic system of wave power device using water as working medium is designed, and compositions of the system and design of hydraulic components are analyzed. The utilization of water as working medium for hydraulic system effectively solves the problems with traditional oil hydraulic transmission and provides a new idea for optimal design of hydraulic system in marine environment. Meanwhile, a monitoring system of hydraulic parameters is designed based on STM32 microcomputer. It is able to monitor pressure, temperature, flow rate and rotational speed in real time. The system is tested under laboratory conditions. The results indicate that the working performance of the hydraulic system is stable, and the monitoring system has high measuring accuracy, which can be used as an effective way to monitor the working state of hydraulic system.
