現場總線FCS 技術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設
備聯機控制系統的CAN 總線節點的設計,對節點的軟、硬件設計進行了詳細的說明。根據系統需要設計了不同類型的CAN 總線節點。節點間通訊方式多樣。系統適合于一個場所多機聯網控制、多樓層設備聯機控制,或對多個特定的場所進行聯網控制等。系統具有擴展性,可將上位機通過特定的CAN 接口器件連接,對系統進行監控。

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
