摘要:

在Linux Rtai平臺(tái)下，對(duì)開(kāi)放式智能化STEP-NC控制器的實(shí)現(xiàn)方法進(jìn)行了研究。引入本體論的方法，建立了一個(gè)數(shù)控專家知識(shí)庫(kù)。采用自主研發(fā)的工業(yè)實(shí)時(shí)以太網(wǎng)現(xiàn)場(chǎng)總線技術(shù)作為控制器底層硬件接口。在嵌入了Rtai實(shí)時(shí)核的通用Linux平臺(tái)上開(kāi)發(fā)了原型機(jī)，驗(yàn)證了設(shè)計(jì)方案的可行性。此數(shù)控系統(tǒng)具有現(xiàn)場(chǎng)編程與重規(guī)劃能力，可進(jìn)行一定的自主決策，支持分布式控制。整個(gè)系統(tǒng)具有開(kāi)放、智能、靈活的特點(diǎn)。

Abstract:

An intelligent STEP-compliant CNC controller was studied and designed under Linux Rtai. A CNC expert knowledge-base was established by importing the theory of ontology. The hardware interface in the bottom layer was realized beyond the self-developed real-time Ethernet fieldbus platform. A prototype was developed under universal Linux with Rtai embedded and the feasibility of this scenario was validated. This CNC controller had the capability of programming and re-planning on the shop floor. It could make decisions by itself to some extent and support distributed control. The whole system was characterized by openness, intelligence and flexibility.
