(ChinaIT.com News) On June 30, my country’s first digital twin intelligent scientific research test ship “Dolphin 1” independently developed by Harbin Engineering University was delivered and made its maiden voyage at Penglai Port, Yantai. It will sail from Penglai to Qingdao, and carry out a series of experiments on the intelligent level and capabilities of ships, such as the verification of ship equipment performance indicators, autonomous navigation and operation, and virtual-real interaction of digital twin systems.
The ship was independently developed by the scientific research team of the School of Intelligent Science and Engineering of Harbin Engineering University in conjunction with several ship-related marine colleges in the school, and solved the reliability design of the ship’s overall system, power, electric power, propulsion, navigation, control, ship-shore and other integrated systems.The hull has a total length of 25 meters and a displacement of 100 tons. It took 3 years to complete the construction.
It is understood thatThe ship is equipped with my country’s first ship digital twin system, and has broken through a number of key technologies.For the first time in China, it has broken through the multi-source information fusion and collaborative detection technology such as laser radar, video image, solid-state radar and sound signal, realized the intelligent perception of the marine environment and small targets, and provided a guarantee for the autonomous navigation of ships; for the first time, it has established ship digital twin technology systems such as ship digital modeling, model iterative evolution, virtual-real real-time interaction, online and offline symbiosis, and ship-shore mirroring. Economical, safe and reliable operation.
The successful development of “Dolphin 1” will effectively promote the practical application and frontier exploration of digital twin technology in my country’s shipbuilding field.
