Abstract

The embodiment of the invention provides a closed-loop control method of a treatment bed, the treatment bed, a control device and a storage medium, and relates to the field of automatic control. Grating ruler parameters and motor parameters are obtained; establishing a coupling relationship between the grating ruler and the motor according to the grating ruler parameters and the motor parameters; controlling the motor to drive the treatment bed to move, and acquiring feedback data of the grating ruler in real time; and controlling the treatment bed to stop moving according to the feedback data of the grating ruler. According to the invention, the parameters of the grating ruler can be adjusted to be synchronous with the parameters of the motor, the effect of full-closed-loop control is achieved, and the problem of low positioning precision of the treatment bed in the prior art is solved.

Description

technical field [0001] The present application relates to the field of automatic control, in particular, to a closed-loop control method of a treatment couch, a treatment couch, a control device and a storage medium. Background technique [0002] At present, with the application of various new technologies in radiotherapy equipment, higher requirements are placed on the positioning accuracy of the treatment couch in radiotherapy equipment. Controlling the movement of the treatment couch through the control device to achieve the positioning of the treatment couch is a research hotspot. . [0003] In the related art, in the radiotherapy equipment, the control of the treatment bed mostly adopts the open-loop control mode, because if the closed-loop control mode is adopted, a control line needs to be arranged between the grating scale and the control device for the control device to control the grating scale. Due to the structural layout of radiotherapy equipment, the related t...
