【摘要】 为了更有效地监测开关状态、提高配电系统供电可靠性 ,以 51单片机为核心处理单元 ,用西门子SPC3专用芯片实现PROFIBUS DP协议 ,研制开发出智能开关量管理器。完成发送变位信号及时标、变位顺序记录、掉电检测、结构参数配置与确认等配电自动化终端的功能 ,这说明以可靠性、互换性、开放性为主要特点的现场总线技术在配电自动化领域有广阔的应用前景。更多还原

【Abstract】 In order to administrate switch status and promote the reliability of distribution system, an intelligent switch signal controller with 51 single chip and SIEMENS SPC3 chip is developed in accord with PROFIBUS DP protocol.The functions of distribution automation such as transmitting switch signal and time, recording the sequence of accidents, administrating power failure,and confirming configuration parameter,etc.,are realized. Being reliable, exchangeable, and liberal, Fieldbus technology will be widely used in automation distribution.更多还原
