【摘要】：激光加工是非接觸加工,具有加工效率高、加工對(duì)象受熱影響較小、加工精度高、能量和光束移動(dòng)速度易于實(shí)現(xiàn)自動(dòng)化控制及不產(chǎn)生噪聲等優(yōu)點(diǎn),已經(jīng)被廣泛地應(yīng)用于眾多工業(yè)領(lǐng)域中。現(xiàn)有激光加工控制系統(tǒng)主要由PC機(jī)、運(yùn)動(dòng)控制卡及激光控制器組成�？墒�,這種的控制系統(tǒng)主要由PC機(jī)來(lái)控制電機(jī)的運(yùn)行,這使得激光加工系統(tǒng)的運(yùn)行離不開PC機(jī),而且這類控制器的系統(tǒng)架構(gòu)比較分散。在了解現(xiàn)有激光系統(tǒng)控制器缺陷的基礎(chǔ)上,本課題研究和實(shí)現(xiàn)一種基于“DSP+FPGA”模式的激光加工控制系統(tǒng)的設(shè)計(jì)。根據(jù)激光加工系統(tǒng)的工作特點(diǎn)和要求,確定了激光加工系統(tǒng)的控制方案,實(shí)現(xiàn)了控制器的軟件和硬件的設(shè)計(jì)開發(fā)。在硬件方面,本課題采用TI公司具有浮點(diǎn)運(yùn)算功能的TMS320F28335作為主控制芯片,對(duì)加工數(shù)據(jù)進(jìn)行運(yùn)算處理,實(shí)現(xiàn)插補(bǔ)算法;以ALTERA公司CycloneⅢ系列的EP3C25Q240C8N作為輔助芯片,將其內(nèi)部M9K存儲(chǔ)空間配置為FIFO,用來(lái)緩存DSP處理好的插補(bǔ)脈沖信息,并在同步信號(hào)的作用下輸出緩存的信息,此外,可以對(duì)控制系統(tǒng)的狀態(tài)進(jìn)行實(shí)時(shí)監(jiān)控以及實(shí)現(xiàn)系統(tǒng)相關(guān)控制邏輯設(shè)計(jì)。除此之外,控制器還可以對(duì)激光器的輸出功率進(jìn)行實(shí)時(shí)調(diào)節(jié)。其中,通過(guò)XINTF接口將DSP和FPGA連接起來(lái)。經(jīng)過(guò)工程樣機(jī)的系統(tǒng)軟硬件聯(lián)合調(diào)試表明,控制系統(tǒng)的性能和功能達(dá)到預(yù)期的設(shè)計(jì)目標(biāo)。
[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，
