It was a distributed control system between the nodes achieving realtime, reliable data munications to provide a strong technical support. Substation information and data sharing and the use of reliable, practical and efficient munication networks and protocols, to optimize the function of substation automation system to improve the level of substation automation system. With the continuous expansion of power network and puter monitoring and control technology, the rapid development of fieldbusbased control system will widely used in power system substations. CAN field bus the thesis based on research it in the substation automation system theory and practical methods of measurement and control network for the shortings of traditional design of a CAN bus is posed by the Fieldbus control network, and discussed in detail the CAN bus technology and its implications for substation automation system. Through a single chip microcontroller for the hardware and software design, making the whole substation within the system to achieve reliable munication between devices possible for the eventual unattended substation provides the conditions for the model..Keywords: CAN bus Microcontroller Netword card 目 錄第一章、緒論 9 9 10 10第二章CAN總線簡(jiǎn)介 12 CAN的技術(shù)特點(diǎn) 12 連接和傳遞方式 12 CAN報(bào)文傳輸 12 CAN控制器 12 CAN總線系統(tǒng)的一般組成 12第三章、 基于CAN總線變電站監(jiān)控系統(tǒng)的總體設(shè)計(jì) 12 CAN總線節(jié)點(diǎn)(下位機(jī))設(shè)計(jì) 12 CAN總線節(jié)點(diǎn)(上位機(jī))設(shè)計(jì) 12第三章、CAN總線節(jié)點(diǎn)(下位機(jī))設(shè)計(jì) 13 14 12 CAN通信模塊設(shè)計(jì) 14 14 14 CAN總線智能節(jié)點(diǎn)系統(tǒng)軟件設(shè)計(jì) 14第4章 、CAN總線節(jié)點(diǎn)(上位機(jī))設(shè)計(jì) 14 PC機(jī)與單片機(jī)串口通信的硬件設(shè)計(jì) 14 軟件設(shè)計(jì) 15 PC機(jī)與單片機(jī)串口通信的軟件設(shè)計(jì) 15第5章 、系統(tǒng)的抗干擾措施 13 硬件抗干擾措施 12 軟件抗干擾措施 12參考文獻(xiàn) 13致 謝 14 第一章 緒論 自80年代初,我國(guó)的超高壓變電所及發(fā)電廠升壓站初步應(yīng)用了微機(jī)監(jiān)控系統(tǒng),最早的河南姚孟電廠SOOKv升壓站、湖北雙河及鳳凰山SOOK變電所,所采用的是從瑞典ASEA公司引進(jìn)的微機(jī)事件順序記錄儀。 本論文以CAN現(xiàn)場(chǎng)總線為基礎(chǔ),研究它在變電站綜合自動(dòng)化系統(tǒng)中的應(yīng)用原理和實(shí)方法,針對(duì)傳統(tǒng)測(cè)控網(wǎng)絡(luò)存在的缺陷,設(shè)計(jì)了一種由CAN總線組成的現(xiàn)場(chǎng)總線型測(cè)控網(wǎng)絡(luò),并詳細(xì)論述了CAN總線的技術(shù)原理及其在變電站自動(dòng)化系統(tǒng)中的應(yīng)用。變電站的信息和數(shù)據(jù)共享及采用可靠、實(shí)用、高效的通信網(wǎng)絡(luò)和協(xié)議,可以優(yōu)化變電站自動(dòng)化系統(tǒng)的功能,提高變電站系統(tǒng)的自動(dòng)化水平。 基于CAN總線的變電站監(jiān)控系統(tǒng)設(shè)計(jì) 摘要現(xiàn)場(chǎng)總線是當(dāng)今自動(dòng)化領(lǐng)域技術(shù)發(fā)展的熱點(diǎn)之一,被譽(yù)為自動(dòng)化 領(lǐng)域的計(jì)算機(jī)局域網(wǎng)。它的出現(xiàn)為分布式控制系統(tǒng)實(shí)現(xiàn)各節(jié)點(diǎn)之間實(shí)時(shí)、可靠的數(shù)據(jù)通信提供了強(qiáng)有力的技術(shù)支持。隨著電力網(wǎng)的不斷擴(kuò)大和計(jì)算機(jī)測(cè)控技術(shù)的飛速發(fā)展,基于現(xiàn)場(chǎng)總
