現(xiàn)場(chǎng)總線FCS 技術(shù)在當(dāng)前自動(dòng)化領(lǐng)域的應(yīng)用越來越廣泛。本文詳細(xì)講述基于工業(yè)設(shè)
備聯(lián)機(jī)控制系統(tǒng)的CAN 總線節(jié)點(diǎn)的設(shè)計(jì),對(duì)節(jié)點(diǎn)的軟、硬件設(shè)計(jì)進(jìn)行了詳細(xì)的說明。根據(jù)系統(tǒng)需要設(shè)計(jì)了不同類型的CAN 總線節(jié)點(diǎn)。節(jié)點(diǎn)間通訊方式多樣。系統(tǒng)適合于一個(gè)場(chǎng)所多機(jī)聯(lián)網(wǎng)控制、多樓層設(shè)備聯(lián)機(jī)控制,或?qū)Χ鄠€(gè)特定的場(chǎng)所進(jìn)行聯(lián)網(wǎng)控制等。系統(tǒng)具有擴(kuò)展性,可將上位機(jī)通過特定的CAN 接口器件連接,對(duì)系統(tǒng)進(jìn)行監(jiān)控。

Abstract: CAN (Controller Area Network) is one of popular field bus and a new kind of network based on micro control unit. The paper introduces the CAN node based on the industrial instruments controlling system and node design of hardware and software. The paper design different CAN nodes which can communicate each other in several modes. The node can be applied in control network which is composed of many special sites or industrial workshops. The system can be monitored through personal computer which connected the CAN bus through special CAN device.
Keywords: Air-Condition Control System; CAN Bus Nodes; Micro Controller
