本文提出了一種基于ARM和Ethernet現(xiàn)場實時動態(tài)信號采集分析系統(tǒng)的軟硬件系統(tǒng)實現(xiàn)方案。該方案通過采用ARM+DSP主從結(jié)構(gòu)、嵌入式LINUX系統(tǒng)及合理任務(wù)分配策略保證了系統(tǒng)的實時性要求，并將網(wǎng)絡(luò)數(shù)據(jù)傳輸率需求控制在可行范圍內(nèi)。討論了Ethernet 應用于工業(yè)測試診斷系統(tǒng)的相關(guān)關(guān)鍵技術(shù)問題。
關(guān)鍵詞: 信號分析; Ethernet; DSP; ARM; 嵌入式LINUX系統(tǒng)
Abstract: This paper presents a realization of real-time dynamic data collection and signal
analysis system based on Ethernet and ARM both in software and hardware. By using ARM+DSP master slave system, embedded LINUX and reasonable task-assigned strategy, the system demand for real-time and data transmission speed of network are guaranteed. Finally, several key technical problems about Ethernet used in industrial tests and diagnosis are discussed.
