A marking system based on ethercat communication

Abstract

The application relates to a scribing system based on EtherCAT communication, which comprises a central control system, which is used as an EtherCAT master station; an EtherCAT communication module; a laser tracker, which is used as an EtherCAT slave station; and an AGV. The central control system is configured to perform the following: resetting the scribing system; receiving BIM / CAD layout information and performing graphic information analysis; according to the analyzed graphic information, obtaining a plurality of motion trajectory information control points and to-be-drawn information, performing motion path planning, and correlating motion control and inkjet information at the motion trajectory information control points; unifying a laser tracker coordinate system of the laser tracker and a layout reference coordinate system of a two-dimensional drawing corresponding to the layout information; starting scribing, and in the scribing process, real-time monitoring of AGV pose and safety is performed, and a flowable inkjet nozzle receives an inkjet instruction sent by a control unit to work. The application can realize efficient automatic scribing.
