1、華北電力大學(xué)碩士學(xué)位論文摘要摘.汪石3丈worldFIP是工業(yè)現(xiàn)場(chǎng)總線(xiàn)的國(guó)際標(biāo)準(zhǔn)之一，符合工EC物理層標(biāo)準(zhǔn)。有冗余的物理總線(xiàn)網(wǎng)絡(luò)和嚴(yán)格的控制信息傳輸機(jī)制。基于溫度測(cè)量裝置在工業(yè)現(xiàn)場(chǎng)的廣泛應(yīng)用，本文開(kāi)發(fā)了一種基于wldFIP總線(xiàn)的多通道智能溫度變送器。為實(shí)現(xiàn)工業(yè)現(xiàn)場(chǎng)設(shè)備可靠性的要求，在考慮工業(yè)現(xiàn)場(chǎng)的惡劣環(huán)境下，本文設(shè)計(jì)了信號(hào)保護(hù)電路、多個(gè)通道的隔離電路、及設(shè)備間安全的連接方式為實(shí)現(xiàn)工業(yè)產(chǎn)品的規(guī)范化指標(biāo)，本變送器提供了標(biāo)準(zhǔn)的共地式4一20m

2、A電流輸出信號(hào)，同時(shí)在WldFIP底層協(xié)議的基礎(chǔ)上定義了一套與上層設(shè)備通信的標(biāo)準(zhǔn)協(xié)議，并且參考FF及工EC61499的標(biāo)準(zhǔn)設(shè)計(jì)了規(guī)范的PID等基本功能塊。在開(kāi)發(fā)的過(guò)程中，完成了儀表所有功能的調(diào)試及在實(shí)際對(duì)象上的測(cè)試工作。關(guān)鍵詞:W6rldFIP，工業(yè)控制，溫度變送器ABSTRACTWOridFIPasoneofthefieldbusstandauls，eonfmstotheIECPhysieallayerstandard.AnditPr
