論文--ftu的硬件結(jié)構(gòu)設(shè)計和軟件設(shè)計

1、摘要隨著對配電網(wǎng)自動化的要求的提高，作為其重要設(shè)備的FTU的性能也應(yīng)提高。針對當(dāng)今市面上的終端設(shè)備的不足，本文嘗試給出一種功能強(qiáng)大、性價比高、可推廣性強(qiáng)的FTU裝置。本設(shè)計采用當(dāng)前流行的嵌入式技術(shù)和數(shù)字信號處理技術(shù)來完成核心處理器，采用以ARM9與TMS320LF2407A有機(jī)結(jié)合的雙CPU構(gòu)架，這種設(shè)計穩(wěn)定、高效、節(jié)能，優(yōu)于以往FTU的核心處理器的設(shè)計。本設(shè)計采用當(dāng)前非常先進(jìn)以太網(wǎng)通信方式，較以往FTU的通信方式網(wǎng)絡(luò)化更強(qiáng)，信息傳輸能

2、力更為強(qiáng)大。本設(shè)計除了在核心處理器和通信方式上有明顯優(yōu)勢外，在其他部分亦有改進(jìn)。希望這種裝置在相當(dāng)長的時間內(nèi)都保持優(yōu)越性。本文講述了筆者對饋線自動化的理解，介紹了設(shè)計過程，給出了FTU的硬件結(jié)構(gòu)設(shè)計和軟件設(shè)計。關(guān)鍵詞：雙CPU，嵌入式，AT91RM9200，TMS320LF2407A，以太網(wǎng)AbstrastAsrequirementsofthedistributionwkautomationincreasingthemajequipme
