Design of Intelligent Detection System for Remote Switch Based on 1-Wire Technology

针对现有远程开关状态检测方法存在传输线多、施工复杂、可靠性差、成本高等缺点,提出了一种基于单总线技术的远程智能开关检测系统的设计方案。该系统采用DS2405单总线器件和C8051F单片机将128点开关组成单总线传感网络,可直接检测各开关的分合状态。实际应用表明,该系统具有电路简单、抗干扰性强、可靠性高等优点。

In view of shortcomings of a lot of transmission line,complicated construction,poor reliability and high cost by use of traditional detection method of remote switch,a design scheme of intelligent detection system for remote switch based on 1-wire was proposed.The system uses DS2405 1-wire device and C8051Fsingle-chip microcomputer to constitute 1-wire sensor network with 128switches and can detect open/close state of switch directly.The practical application showed that the system has advantages of simple circuit,strong anti-interference and high reliability.
