Abstract

The invention discloses a numerical control machine tool motion control card based on WIFI communication. The motion control card uses an ARM chip as a main controller and uses an FPGA chip as a hardware architectural structure of a coprocessor. A peripheral circuit of the ARM chip includes a reset circuit, a real-time clock circuit, an SDRAM, a FLASH storage module and various communication interfaces, needs to complete a communication task with a host computer, calculates motion codes and instructions transmitted by the host computer and finally process and form interpolation data and IO logic data to transmit to an FPGA for execution. According to the numerical control machine tool motion control card based on the WIFI communication, the advantages of a novel numerical control system mode are compared with that of a traditional numerical control system mode, the feasibility of using a WIFI wireless communication mode is analyzed from the perspective of real-time control and safety reliability, the wireless communication data frame format design and detailed semantic definition are achieved, and the data verification is based on reliable hardware CRC in order to improve the real-time communication.

Description

technical field [0001] The invention relates to the technical field of an integrated embedded numerical control system used in a numerical control cutting machine, and more particularly relates to a movement control card of a numerical control machine tool based on WIFI communication. Background technique [0002] The traditional small portable CNC cutting machine uses an integrated embedded CNC system, which often integrates multiple functions such as display, function keys, and motion control. Due to the harsh environment of the riveting and welding factory, the system display and buttons are easily damaged, the repair rate is high, and it needs to be returned to a professional manufacturer for repair, which affects production efficiency and production costs. [0003] Based on the present situation of the numerical control system, the present invention proposes a new type of numerical control system mode. The main difference between this mode and the traditional mode is: (...
