Abstract
Official abstract text for this publication.
A control method based on a single-power caching mechanism. The single-power caching mechanism comprises an active coiling block, a driving motor, passive coiling blocks, and a tape coiling. The active coiling block is disposed on the driving motor. The active roiling block and the passive coiling blocks are connected through the tape coiling. The control method comprises the following steps: 1) when the driving motor needs to be shut down, detecting a rotational inertia of the active coiling block, a semidiameter of the active coiling block, a semidiameter of the passive coiling blocks, and a rotational inertia of the passive coiling blocks; and 2) controlling a breaking torque of the driving motor to be M 1 ≦I 1 ×r×M 2 /(I 2 ×R), M 2 being a torsional moment of the passive coiling blocks. Also disclosed is a control system based on a single-power caching mechanism. When the breaking torque M 1 of the driving motor is controlled to be smaller than or equal to I 1 ×r×M 2 /(I 2 ×R), it can be ensured that the active coiling block and the passive coiling blocks remain a same operation state in a process of reducing the speed until they are static completely, rotational distances are equal and the tape coiling is straightened.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for controlling a caching mechanism based on single-power, wherein the caching mechanism based on single-power comprising a drive roll, a driving motor, a driven roll and a tape, with the drive roll being disposed on the driving motor, and the drive roll and the driven roll being connected with each other through the tape, wherein the method comprises: 1) detecting the moment of inertia I 1 of the drive roll, the radius R of the drive roll, t…
