Abstract

The invention relates to a high-speed industrial sewing machine control system based on CPU and FPGA structures, comprising a control unit, a memory, a position sensor, an motion unit, an operation display unit, a power supply unit, a auxiliary action unit adopting switching value of input and output and a pedal as a system; wherein the control unit of the invention comprises a master control CPU, FPGA, a front-wheel input and output control panel and a liquid crystal version display device; the memory is used to store system software and data files generated during the operation of the system; the position sensor fixes the position of a machine needle; the motion unit of the invention comprises a spindle servo motor and a multi-way stepping motor; the operation display unit of the invention comprises a control panel; the power supply unit of the invention comprises a switch power supply. The invention mainly uses the CPU and FPGA structures in the control unit; the communication and data access among each unit and the control of the spindle servo motor are completed by the master control CPU; the parts with requirement on fast reaction speed and more calculation workload is completed by FPGA, thereby reducing the load of the main control CPU and improving the operation speed of the speed of industrial sewing machines.

Description

technical field [0001] The invention relates to the control field of industrial sewing machines, in particular to a high-speed industrial sewing machine control system based on CPU and FPGA structure. Background technique [0002] With the improvement of industrial production technology, the profits of production-oriented enterprises are closely related to the production speed of their equipment. Various industries are constantly improving the operating speed of equipment to increase production rates and thus gain more profits. This is also the case in the leather processing industry. The control system of the current industrial sewing machine is either very slow, or the price is very expensive, or the sewing lines or patterns are not ideal. The high-speed industrial sewing machine control system using CPU and FPGA structure is not only cheap, but also fast. Through software optimization, it can accurately sew various complex lines and patterns, greatly improving production...
