【摘要】 该文针对目前居民楼、学生公寓等用户比较集中的场所的电能计量和集中抄表问题,研究设计了一款单相多功能数字电能表。该表可以对电压、电流、有功功率、功率因数、有功电能等进行高精度实时测量、显示和保存。该表内部集成了低压电力线载波通信模块,可以定时把采集到的信息通过集中器发往上位机。不需要另外架设专用通信线路,利用现有的电力线便可以实现远程自动抄表。更多还原

【Abstract】 Aiming at the electric energy metering and concentration meter reading problems in the dweller building or student’s apartment,in this paper we desined a single-phase multi-function digital power meter.By this meter,a real-time measurement with some electrical parameters such as voltage,current,active power,power factor,active electrical energy,can be realized accurately.It integrates low voltage power line carrier communication module,so remote automatic meter reading can be realized using of existing power lines without setting up dedicated communication line.更多还原
