現(xiàn)場總線FCS 技術(shù)在當前自動化領域的應用越來越廣泛。本文詳細講述基于工業(yè)設
備聯(lián)機控制系統(tǒng)的CAN 總線節(jié)點的設計,對節(jié)點的軟、硬件設計進行了詳細的說明。根據(jù)系統(tǒng)需要設計了不同類型的CAN 總線節(jié)點。節(jié)點間通訊方式多樣。系統(tǒng)適合于一個場所多機聯(lián)網(wǎng)控制、多樓層設備聯(lián)機控制,或?qū)Χ鄠€特定的場所進行聯(lián)網(wǎng)控制等。系統(tǒng)具有擴展性,可將上位機通過特定的CAN 接口器件連接,對系統(tǒng)進行監(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
