摘要
设计了一种基于CAN总线的智能楼宇温度测控系统。以AT89S52单片机为核心,利用CAN总线技术和数字温度传感器DS18B20,组建了智能楼宇温度测控系统的节点及网络架构,给出了系统总体结构和关键的软件流程。测试结果表明,房间温度控制能满足设计要求,具有结构简洁、节能、实时性好及可靠性高等优点。
A temperature measurement and control system based on CAN bus for intelligent buildings has been designed. Taking AT89S52 single-chip microcomputer as the core, CAN bus technology and digital temperature sensor DS18B20 are used to set up a node and network structure of the temperature measurement and control system for intelligent buildings, and the overall structure of the system and key software flow are given. The measuring results show that the control of the room temperature can meet the design requirements, and the system has advantages of a simple strueture, energy-saving, good real-time performance and high reliability.
