根据雕刻机控制系统的设计需求,采用TI公司的32bit定点数字信号处理器TMS320F2812作为下位机控制系统核心处理单元,并与FPGA相结合取代目前市场上主流的单片机与高速运动控制芯片相结合的联机控制.运用模块化设计思想进行了雕刻机控制系统软硬件设计.在轨迹控制中,运用快速数字积分插补算法替代普通数字积分插补算法,使控制器对插补过程的运算效率更高,减小了控制器的运算压力;试验证明了所设计的基于DSP和FPGA的三维雕刻机数控系统方案及数字积分改进算法的可行性和可靠性,雕刻机的加工速率提高了大约20%.
According to the engraving machine control system design requirements, using TI’s 32bit fixed-point digital signal processor TMS320F2812 as the next crew control system core processing unit, and the combination of FPGA to replace the current market, the mainstream of single-chip microcomputer and high-speed motion control chip combination of online Control.The hardware and software design of the engraving machine control system is implemented by using modular design idea.In the trajectory control, the fast digital integral interpolation algorithm is used instead of the common digital integral interpolation algorithm to make the controller more efficient in the interpolation process, Which reduces the calculation pressure of the controller. The feasibility and reliability of the numerical control system scheme and the digital integral improvement algorithm of the designed three-dimensional engraving machine based on DSP and FPGA are verified. The processing speed of the engraving machine is increased by about 20%.
