【摘要】:隨著計(jì)算機(jī)技術(shù)的飛速發(fā)展,為數(shù)控系統(tǒng)的發(fā)展提供了豐富的軟硬件資源。開(kāi)放式數(shù)控系統(tǒng)中所有具有運(yùn)動(dòng)控制功能可以完全在PC中通過(guò)軟件實(shí)現(xiàn),實(shí)現(xiàn)硬件功能軟件化。 針對(duì)開(kāi)放式數(shù)控系統(tǒng)的開(kāi)發(fā)特點(diǎn),結(jié)合本實(shí)驗(yàn)室的研究項(xiàng)目,本文開(kāi)發(fā)出了開(kāi)放式的嵌入式數(shù)控系統(tǒng)。本系統(tǒng)采用軟件實(shí)現(xiàn)運(yùn)動(dòng)控制的功能,增強(qiáng)了數(shù)控系統(tǒng)的穩(wěn)定性、可靠性、易擴(kuò)展性和易維護(hù)性,使得數(shù)控系統(tǒng)只要進(jìn)行小范圍改動(dòng)就能滿足不同應(yīng)用的需要,從而縮短了數(shù)控系統(tǒng)的開(kāi)發(fā)周期、降低了開(kāi)發(fā)成本。充分利用了PC機(jī)不斷提高的計(jì)算速度、不斷擴(kuò)大的存儲(chǔ)量和性能不斷優(yōu)化的操作系統(tǒng)。 本論文的主要研究?jī)?nèi)容包括: 在分析數(shù)控系統(tǒng)的發(fā)展現(xiàn)狀和發(fā)展趨勢(shì)的基礎(chǔ)上,確定以開(kāi)放性的嵌入式數(shù)控系統(tǒng)作為研究方向。設(shè)計(jì)出了嵌入式數(shù)控系統(tǒng)的體系結(jié)構(gòu),按照軟硬件的角度劃分為軟件結(jié)構(gòu)和硬件結(jié)構(gòu)并分別進(jìn)行了設(shè)計(jì),采用ARM開(kāi)發(fā)板作為數(shù)控系統(tǒng)的硬件平臺(tái),Linux作為操作系統(tǒng),使得軟硬件都有很高的穩(wěn)定性和可移植性。 針對(duì)嵌入式開(kāi)發(fā)的特點(diǎn),在ARM平臺(tái)和Linux操作系統(tǒng)上搭建起了嵌入式開(kāi)發(fā)環(huán)境,包括編譯環(huán)境、圖形基礎(chǔ)環(huán)境和圖形用戶界面環(huán)境的搭建,,并使用Tcl/Tk和GTK完成數(shù)控系統(tǒng)界面的設(shè)計(jì)和開(kāi)發(fā)。 由于數(shù)控系統(tǒng)運(yùn)動(dòng)控制部分對(duì)系統(tǒng)實(shí)時(shí)性要求比較高,在分析Linux實(shí)時(shí)性不足的基礎(chǔ)上,探討了Linux實(shí)時(shí)化方法,針對(duì)本文所研究平臺(tái)的特點(diǎn),采用Xenomai的實(shí)時(shí)化技術(shù)對(duì)Linux內(nèi)核進(jìn)行重新編譯和配置,搭建完成Xenomai/Linux雙內(nèi)核實(shí)時(shí)操作系統(tǒng)。 完成了數(shù)控系統(tǒng)的整體設(shè)計(jì),并將本文硬件平臺(tái)上完成的數(shù)控系統(tǒng)和Intel平臺(tái)上的兩種不同處理器上的數(shù)控系統(tǒng)進(jìn)行了比較,測(cè)試了Xenomai/Linux雙內(nèi)核實(shí)時(shí)操作系統(tǒng)的實(shí)時(shí)性,并通過(guò)G代碼測(cè)試了數(shù)控系統(tǒng)的性能。
[Abstract]:With the rapid development of computer technology, abundant software and hardware resources have been provided for the development of CNC system. All the motion control functions in open CNC system can be realized by software in PC, and the hardware function can be realized by software. According to the characteristics of the open CNC system and the research project of our laboratory, the open embedded NC system is developed in this paper. The system uses software to realize the function of motion control and enhances the stability of the NC system. The reliability, expansibility and maintainability of the NC system make it possible to meet the needs of different applications as long as the numerical control system is changed in a small range, thus shortening the development period of the CNC system. It reduces the cost of development, makes full use of the increasing computing speed of PC, the increasing storage capacity and the continuous optimization of performance of the operating system. The main contents of this thesis are as follows:. Based on the analysis of the present situation and development trend of CNC system, the open embedded CNC system is chosen as the research direction. The architecture of embedded CNC system is designed. It is divided into software structure and hardware structure according to the point of view of hardware and software. ARM development board is used as the hardware platform of CNC system as operating system, which makes both hardware and software have high stability and portability. According to the characteristics of embedded development, the embedded development environment is built on ARM platform and Linux operating system, including compiling environment, graphic basic environment and graphical user interface environment. And use Tcl/Tk and GTK to complete the design and development of NC system interface. Because the motion control part of NC system requires high real-time performance of the system, on the basis of analyzing the lack of real-time performance of Linux, this paper discusses the method of Linux realtime, aiming at the characteristics of the platform studied in this paper. The Linux kernel is recompiled and configured by the real-time technology of Xenomai, and the Xenomai/Linux dual kernel real-time operating system is built. The whole design of the NC system is completed, and the real-time performance of the Xenomai/Linux dual-kernel real-time operating system is tested by comparing the NC system completed on the hardware platform of this paper with that on two different processors on the Intel platform. The performance of NC system is tested by G code.
