Research Of Solar Sightseeing Ship Energy Management System Based On DSP

In twenty-first Century, the issues of energy and environmental protection have beencaused close attention by people. Solar energy as one of a clean, non-polluting and renewableone everlasting energy, which must be become a hot topic in the field of energy research, but alsoachieve the important content of the sustainable development strategy in countries. With theadvantages of no pollution, low noise, and so on, solar sightseeing ship has become more andmore popular in the water tourism industry. As one of the key technologies of solar sightseeingship, the energy management system is the key to realize safe, reliable and high efficiencyoperation of the solar sightseeing ship. Therefore, the solar sightseeing ship energy managementsystem is designed with TMS320F2812DSP as the core controller, and the design concept andimplementation way of the energy management system are described.Firstly, the technology of photovoltaic power generation, the composition module ofphotovoltaic power generation system and the function of each module are introduced, and thenthe key issues of photovoltaic power generation system in ship applications and the feasibilitiesof photovoltaic power generation system in the sightseeing ship applications are analyzed.Aiming to the actual demand of solar sightseeing ship, the power system network topology isdesigned based on the distributed DC bus, and the power management control strategy isproposed on the base of solar sightseeing ship actual working conditions.Secondly, the overall design schemes of the solar sightseeing ship energy managementhardware system are analyzed. The data acquisition unit is designed based on DSP, it is mainlyachieved the data of overall battery pack voltage, cell voltage, temperature and solar powersystem, electric propulsion system voltage and current collection. CAN bus technology and thecombination of serial communication are used to design the sightseeing ship data communicationsystem. This paper that using CAN bus transfer the data acquisition system collected data to themain controller TMS320F2812DSP and then through the main controller’s serialcommunication interface RS-232that using Modbus protocol to upload data to the monitorsystem of MCGS.Finally, the software programming part of the solar sightseeing ship energy managementsystems are introduced, it is mainly including the acquisition data of voltage, current andtemperature acquisition program design, CAN bus communication software design, DSP andTouch screen MCGS communication program design, and the energy management control system is designed by using the MCGS configuration software. It is proved that the managementsystem to meet the design requirements and verify the feasibility of the design ideas through theconstruction of experimental platform, system operation and the experimental results.
