2results about How to "Continuous motion" patented technology

This application relates to the field of computer-aided design technology, and provides a method, apparatus, terminal device, and storage medium for dragging geometric elements based on differential equations. The method includes: acquiring the starting point, target point, and first constraint conditions corresponding to the geometric element in the user's dragging operation; constructing a target equation based on the starting point, target point, and first constraint conditions; constructing a differential equation based on the target equation; solving the differential equation to obtain multiple intermediate dragging points that satisfy the first constraint conditions; and substituting these intermediate dragging points into the target equation to obtain the dragging trajectory of the geometric element from the user to the target point. This method ensures constraint preservation, motion continuity, and real-time computation during the dragging process of geometric elements in computer-aided software.

The invention relates to the technical field of photovoltaic slicing equipment control, in particular to an active control guide wheel system and method for a photovoltaic diamond wire slicer, and the system comprises a left wire wheel and a right wire wheel which are respectively used for winding and unwinding a diamond wire; the plurality of guide wheels are arranged between the left wire wheel and the right wire wheel; the servo motor driving unit comprises a servo motor which is independently equipped for each guide wheel; the tension monitoring unit is used for collecting tension data of the diamond wire in real time and feeding back the tension data to the central controller; the main shaft motor is used for driving the cutting main shaft to rotate and providing main shaft linear velocity data for the central controller; the take-up and pay-off motor drives the left wire wheel and the right wire wheel to achieve take-up and pay-off movement of the diamond wire. And the central controller is in communication connection with the servo motor driving unit, the main shaft motor and the take-up and pay-off motor, and is used for adjusting the rotating speed of each guide wheel by adopting a high-dynamic PID control algorithm based on the diamond wire tension data acquired by the tension monitoring unit in real time.
