前言：數(shù)控系統(tǒng)的產(chǎn)生和發(fā)展一直都與計算機技術(shù)密切相關(guān)。如何進一步提高數(shù)控系統(tǒng)的開放性、實時性、可靠性、集成度與人機交互的友好性,降低成本與功耗,是新一代數(shù)控系統(tǒng)必須考慮的問題。而嵌入式系統(tǒng)正以其此類諸多優(yōu)點,被越來越廣泛地應(yīng)用于數(shù)控系統(tǒng)之中,成為新一代數(shù)控系統(tǒng)的發(fā)展方向之一。ARM體系結(jié)構(gòu)的處理器,處理速度快、超低功耗、價格低廉、集成度高。Windows CE.NET嵌入式操作系統(tǒng)以其強大的通信能力、優(yōu)秀的人機交互功能、大大提高的實時性、完善的配套開發(fā)工具、很好的軟件集成度以及對諸多處理器的完美支持,在嵌入式領(lǐng)域得到了廣泛的應(yīng)用。正是基于這些考慮,本文對采用XScale處理器和Windows CE.NET操作系統(tǒng)的嵌入式數(shù)控系統(tǒng)軟硬件相關(guān)技術(shù)做了一些研究。論文主要內(nèi)容包括: 1)從數(shù)控系統(tǒng)開發(fā)要求入手,對數(shù)控系統(tǒng)的軟硬件體系結(jié)構(gòu)進行了研究。 2)結(jié)合數(shù)控系統(tǒng)的進一步開發(fā)要求,給出了數(shù)控系統(tǒng)硬件平臺的嵌入式解決方案,包括處理器、處理器周邊的一些模塊、數(shù)控系統(tǒng)與執(zhí)行部件的接口(進給控制接口、主軸控制接口等)以及以單片機為核心的內(nèi)置式PLC等。 3)分析了Windows CE.NET操作...
    The produce and development of Numerical Control System has long been correlated with the development of computer technology very closely. It is inevitable for the next generation NC that we consider how to improve its openness, real-time ability, reliability, integration and friendliness of HMI (Human-Machine Interaction) as well as reduction of the cost and power consumption. Because of those advantages mentioned above, the embedded CNC system is widely used in CNC and has become one of the operatio...
