【摘要】 针对低压电力线载波抄表存在的诸多问题,利用频段470~477MHz的微功率无线抄表是用电信息采集的有效抄表模式,以其低成本、低功耗、接线方便简洁、自动中继节点的优点有效实现电力用户自动抄表的全覆盖和全采集。本文设计了低功耗的无线抄表采集器、集中器,其与配变监控终端构成无线抄表系统,该系统在我国某农村地区的两个配变台区进行了试点安装。运行结果表明,微功率无线自组网技术在农村低压电力集中抄表中运行可靠、数据正确上传,免去了每月月底台区电工手动抄表的巨大工作量。更多还原

【Abstract】 Many problems existing in the meter reading of low-voltage power line carrier,micro-power wireless reading whose reading band is effective meter reading of the information collection for 470 to 477MHz.With its low-cost,low power,simple and easy to connect and automatic relay node,it realizes the full coverage and whole colletion for electricity users in automatic meter reading.The paper introduces the design of low power wireless meter reading collector,concentrator and the wireless reading system which composed by the two and distribution transformer monitoring terminal.This system is conducted a pilot program to install in rural area.The wireless meter reading system operation results show that the system in rural voltage power is reliable for operation and correcting data upload,which avoids the huge work of manual electrical meter reading at the end of the month.更多还原
