【摘要】 当今楼宇的中央空调,为了节约能源和合理收费,通常都采用计算机进行监控管理,但实施中遇到布线复杂、施工麻烦和维护费用偏高等问题。为此设计了基于单总线技术的中央空调监控管理系统的新技术方案。文中简介了单总线技术和用于该系统的三个器件(DS18B20数字温度计、DS2423电子计数器和 DS2406程控开关),给出了系统的组成框图和关键部件的工作原理及软件设计要点。由于该方案具有性价比高、可靠性好等优点,故具有较好的经济效益和社会效益。更多还原

【Abstract】 For energy conservation and reasonable toll,it usually uses computers for central air-condition to monitoring and management today.But there are many problems in practice,such as complex routing,diffi- cult construction and higher maintaining cost.For this reason,the paper proposes a new scheme for central air-condition monitored control system based on 1-wire bus technology.The technology and three devices used 1-wire bus are introduced.And block diagrams of the system,the principle of key components and de- sign features in software development are also demonstrated.Because of higher cost performance and relia- bility,the scheme yields good economic and social benefit.更多还原
