【摘要】：激光加工是非接觸加工,具有加工效率高、加工對象受熱影響較小、加工精度高、能量和光束移動速度易于實現自動化控制及不產生噪聲等優(yōu)點,已經被廣泛地應用于眾多工業(yè)領域中�，F有激光加工控制系統主要由PC機、運動控制卡及激光控制器組成。可是,這種的控制系統主要由PC機來控制電機的運行,這使得激光加工系統的運行離不開PC機,而且這類控制器的系統架構比較分散。在了解現有激光系統控制器缺陷的基礎上,本課題研究和實現一種基于“DSP+FPGA”模式的激光加工控制系統的設計。根據激光加工系統的工作特點和要求,確定了激光加工系統的控制方案,實現了控制器的軟件和硬件的設計開發(fā)。在硬件方面,本課題采用TI公司具有浮點運算功能的TMS320F28335作為主控制芯片,對加工數據進行運算處理,實現插補算法;以ALTERA公司CycloneⅢ系列的EP3C25Q240C8N作為輔助芯片,將其內部M9K存儲空間配置為FIFO,用來緩存DSP處理好的插補脈沖信息,并在同步信號的作用下輸出緩存的信息,此外,可以對控制系統的狀態(tài)進行實時監(jiān)控以及實現系統相關控制邏輯設計。除此之外,控制器還可以對激光器的輸出功率進行實時調節(jié)。其中,通過XINTF接口將DSP和FPGA連接起來。經過工程樣機的系統軟硬件聯合調試表明,控制系統的性能和功能達到預期的設計目標。
[Abstract]:Laser machining is a non-contact machining, which has the advantages of high processing efficiency, less heat effect, high machining accuracy, easy automatic control of energy and beam speed, and no noise. Has been widely used in many industrial fields. The existing laser processing control system is mainly composed of PC, motion control card and laser controller. This kind of control system is mainly controlled by PC, which makes the operation of laser processing system inseparable from PC. Moreover, the system architecture of this kind of controller is more dispersed. On the basis of understanding the defects of the existing laser system controller. The design of laser machining control system based on "DSP FPGA" mode is studied and realized in this paper. According to the working characteristics and requirements of laser machining system, the control scheme of laser machining system is determined. The software and hardware of the controller are designed and developed. In the aspect of hardware, the TMS320F28335 of TI company with floating point operation function is used as the main control chip. The processing data is processed and the interpolation algorithm is realized. The internal M9K storage space is configured as FIFO with EP3C25Q240C8N of Cyclone 鈪，
