Description

technical field [0001] The invention relates to the technical field of computer automation control, in particular to an integrated control system of machine vision, motion controller and servo driver. Background technique [0002] The existing machine vision positioning system mainly includes three parts: image processor, motion control card and servo drive system. The respective functions of the three are: image processor collects image data and performs related processing such as denoising and matching; The controller plans the movement trajectory according to the given position and speed instructions and sends the movement instructions to the servo driver; the servo driver converts the movement instructions into switching signals, and controls the motor to complete the corresponding movement by controlling the on-off of the driving power module. [0003] At present, the image processor, motion control card and servo drive system of the machine vision positioning system ar...

Problems solved by technology

Since the control algorithm of the controller requires real-time image data feedback to achieve closed-loop control, the motion controller and the servo driver are in a waiting state during the image data transmission process, which seriously affects the control efficiency and real-time performance, and thus cannot obtain fast and high-precision positioning control
