An Embedded Controller of Turntable Knife Grinder Based on Digital Bus

Abstract

The invention discloses a rotary grinder embedded controller based on a digital bus, comprising an ARM processor, an FPGA processor, an LCD touch screen, a bus interface, a motion feedback interface, and a power supply. The ARM processor is integrated with rich motion control algorithms and a PLC process control engine. The FPGA processor calculates motion parameters and transmits the motion parameters to the ARM processor, and control data is generated by the motion control algorithms of the ARM processor to control forward and reverse rotation, speed, position and torque of a servo motor, complete closed-loop control on speeds, positions and torques of shafts, and realize linkage between multiple shafts. The LCD touch screen provides a man-machine interactive interface, and user instructions and the motion parameters are input through the touch screen and are transmitted to the ARM processor and the FPGA processor. The bus interface realizes complete machine multi-shaft linkage and IO data exchange through communication between multiple nodes. The motion feedback interface feeds back the motion state of each shaft of the rotary machine in real time, and feeds the information back to the FPGA processor. The controller of the invention enables real-time and efficient control on shaft motors of the rotary machine to be realized.

Description

technical field [0001] The invention relates to the field of automatic production and processing of hardware products, in particular to an embedded controller of a turntable knife sharpener based on a digital bus. Background technique [0002] With the needs of social production, embedded technology and bus technology have been more and more widely used in the field of industrial control and production, and the embedded controllers at home and abroad are also constantly developing and progressing. For the rotary table sharpener, most domestic enterprises still use the hydraulic control method, and the general-purpose CNC system cannot meet the specific process requirements due to the lack of pertinence of functions; the existing control system of the rotary table knife sharpener is mostly through PLC (can be Programmable logic controller), but this method is more suitable for single-axis or double-axis control, and multi-axis linkage will face the problems of high hardware c...
