Turntable control system and method

Abstract

A control system of a rotary table and a sample analyzer. The system is based on a rotary table driven by a motor and comprises: a control unit (102) configured to receive a rotary table control instruction, convert the rotary table control instruction into a corresponding rotary table rotation parameter corresponding to the rotary table control instruction, and send the rotary table rotation parameter to an execution unit (104); the execution unit (104) configured to drive a rotary table driving unit (108) to rotate according to the rotary table rotation parameter; and a position sensor unit (106) configured to detect rotary table position information of the rotary table and send the information to the execution unit (104). The position sensor unit is provided with a plurality of trigger positions, and the trigger position move along with the rotary table in the rotation process of the rotary table. The execution unit (104) is further configured to determine whether the rotary table arrives at a specified position according to the rotary table position information, if yes, a rotary table control state parameter is modified into a motion completed state, and the control unit (102) is further configured to detect the rotary table control state parameter and return, under the condition of the motion completing state, prompt information that a motion is normally completed.

Description

technical field [0001] The invention relates to the technical field of industrial control, in particular to a control system and method for a turntable. Background technique [0002] In the field of numerical control, it is necessary to precisely control the number of turns and the angle of the turntable movement. However, during the high-speed rotation of the turntable, due to motion inertia and other reasons, the position control of the turntable cannot meet the requirements of precise product processing. That is to say, for the movement of the turntable, the angle offset is caused by the braking distance, the control precision is not enough, and the corresponding control effect cannot be achieved. [0003] In the prior art, the photoelectric encoder is used to feed back the position information of the turntable in real time, thereby realizing the closed-loop control of the turntable, thereby improving the accuracy of the position control of the turntable and ensuring the...
