Abstract: At present, there are many problems in China's ship coating production, such as the low level of intelligence and information technology, high manual management costs, low operating efficiency, and low energy utilization. Aiming at these issues, we carry out the research on intelligent coating equipment, coating data integration processing, refined production management system and energy management system. Through the research of intelligent coating, a complete set of shipbuilding intelligent coating production line is established, with field bus control technology and advanced wireless communication technology being the core of control. This production line can be duplicated and popularized. The research results are piloted at Shanghai Waigaoqiao Shipbuilding and Offshore Co., Ltd.
