The invention relates to the technical field of data recommendation, in particular to a learning plan making method and device. The method comprises the steps: obtaining reference information for making a learning plan; judging whether the learner completes the learning plan according to a standard, if so, providing an entrance for the learner to perform autonomous learning, and if not or standards are not met after completion, closing the entrance for the learner to enter the autonomous learning; and judging whether the learner completes the learning plan according to the standard or not to determine whether to open or close the self-learning entrance. Therefore, a technical problem that students do not learn according to plans made by teachers and learn blindly by themselves is solved, and the technical effects that the teachers control learning items and learning effects of the students, and course plans of the teachers can be helped to be executed more smoothly are achieved. And the technical problem that the students answer the questions disorderly or do not learn the learning plan carefully is solved, so that the technical effect of improving the learning efficiency is achieved.

The invention belongs to the field of unmanned boats and discloses a Bi-RRT unmanned boat multi-boat navigation method and equipment that considers rotation angle constraints. This method uses global task allocation and considers each unmanned boat route connected by nodes based on the assigned task planning, performs collision judgment and coordinated collision avoidance on route nodes, and determines whether the unmanned boat reaches the corresponding target point through node release. Finally, Until all unmanned boats arrive at the target point. The entire process considers the large scene, multi-tasking and flexibility of the unmanned ship, so the route planning should ensure efficiency. In the route planning algorithm of Bi-RRT, which considers the rotation angle constraints, the rotation angle constraints at the end of the expansion node and the connecting node are considered to adapt to the situation. The movement constraints of the human boat, with heuristic expansion, make the expansion of the tree more greedy and clear, and more efficient.

The invention discloses a vertical-shaft wind turbine rotary spindle vibration restraining method which is high in wind energy capturing efficiency. The method includes: acquiring vertical inclination angle of a rotary spindle in real time; calculating vibration intensity of two orthogonal directions in a horizontal section of the rotary spindle and optimal rotation speed of a wind turbine generator under a maximum tracking target; determining expected rotation speed; allowing a rotating speed inner ring controller to drive the rotation speed to reach the expected rotation speed fast; and starting a reverse electric braking function of the rotating speed inner ring controller and a electromagnetic braking mechanism of the rotary spindle when vibration intensity of the spindle exceeds a preset safety regulating threshold; wherein fast rotating speed regulating of the rotating speed inner ring controller is achieved by motor acceleration through directly cutting of part of phase winding excitations or motor deceleration through releasing current chopping limits.
