Design and research on intelligent ventilation system of ship cargo hold

Abstract

Ventilation in the cargo hold of ships, which can adjust the temperature and humidity in the cargo hold, is a necessary measure to ensure the safety of maritime cargo. Traditional ship cargo hold ventilation includes natural ventilation and mechanical ventilation. Its ventilation effect is limited, which often leads to cargo damage accidents such as mildew of the cargo in the cabin. Based on the research of intelligent cargo hold ventilation technology, this paper proposes a design scheme of ship cargo hold ventilation system. The ventilation system includes a system platform and electrical connection elements supported by the system platform. Among them, the system platform is electrically connected to the concentrator, the concentrator is electrically connected to several collectors and electric control devices, the collector is electrically connected to several collection nodes, and the electric control device is electrically connected to the ventilation device. The collection nodes of the ventilation system, including temperature and humidity sensors, air pressure sensors, and wind speed and direction sensors, are installed in the cargo hold of the ship. The collection nodes are evenly distributed in multiple locations in the cargo hold of the ship, effectively monitoring the temperature, humidity, air pressure, wind speed and direction of the cargo hold of the ship, and transmitting it to the system platform through collectors and concentrators to realize real-time monitoring. According to the setting of different environmental standard values, it can automatically complete the startup, shutdown and reverse operation of the wind turbines in different positions, making the system more accurate in monitoring the environment of the ship’s cargo hold, effectively reducing cargo damage, ensuring the safety and economy of maritime freight, and It can more effectively save energy, reduce carbon emissions, protect the environment, and make the system more practical.
