Patent number: 11965942Abstract: A measurement apparatus includes an Epstein frame, an alternating power supply, a power analyzer, and an oscilloscope. Electromagnetic coupling modeling on an Epstein frame is performed based on a vector model of a magnetic circuit, where an iron core of the Epstein frame is formed by laminating a silicon steel sheet to be measured, and an excitation coil and a detection coil with the same turns number are wound around the iron core. The measurement process is to first obtain a reference B-H curve that only considers a nonlinear reluctance of the iron core, and then to derive a B-H curve considering an eddy current effect in a magnetic field at any frequency from the reference B-H curve. The method, applicable to a measurement for B-H curves at middle and high frequencies, may obtain much higher accuracy.Type: GrantFiled: January 22, 2021Date of Patent: April 23, 2024Assignee: SOUTHEAST UNIVERSITYInventors: Ming Cheng, Xinkai Zhu, Wei Qin, Zheng Wang

Patent number: 11941553Abstract: The embodiment of the present disclosure discloses a method, an electronic device, and a storage medium for a ship route optimization. The method for the ship route optimization considers a dynamic feature of a multi-functional emergency rescue ship and an interference effect caused by an airflow, uses a movement model with kinematics non-holonomic constraints, such as a ship total cost assessment function to simulate the movement of the ship, and based on a sparrow search algorithm, learns how to apply the algorithm to a route plan of the emergency rescue ship. The method can improve the ship route optimization algorithm, improve an accuracy and practical applicability of a calculated plan. The method can effectively and accurately locate obstacles and hidden reefs, and consider effects of an airflow and a non-holonomic constraint effect, so as to make the route planning of the ship more efficient and intelligent.Type: GrantFiled: July 5, 2023Date of Patent: March 26, 2024Assignees: HEFEI UNIVERSITY OF TECHNOLOGY, ANHUI CONSTRUCTION ENGINEERING TRAFFIC & SHIPPING GROUP CO., LTD.Inventors: Jingyu Yu, Jingfeng Wang, Wei Lin, Yuxue Pu, Yongchao Zhu, Zhenxuan Li, Qiong Zhang, Yuming Zhang, Yonggen Gu, Zheng Qiu
