基于87C51单片机的复费率电能表的设计

Application of single chip computer 87c51 in multi-rate watt-hour meter

讨论了一种以87c51单片机为核心处理器的多功能复费率电能表,该表具有电量采集、分段计费、电子显示、远红外无线操表等功能,适合我国目前电力供应紧张和用电负荷不平衡的需求,同时也可减轻人工抄表的劳动强度.该表以87C51为核心控制单元,以ADE7755作为电量采集芯片,以高清晰的 LCD 作为显示屏来显示系统中谷、峰、平等各时段的电能值,具有结构简单,可靠性高和成本低等特点.

Single-phase Multi-Functional and Multi-Rate Watt-Hour Meter based on Single Chip Computer 87c51 is introduced.It has many functions such as kilowatt-hour meter,measuring electric energy indifferent time intervals,displayed on the screen of the advanced LCD,receivering data through infrared far distance data communication and so on.To meet the demand of the emergency of electric supply,the imbalance of electric load and to lighten the labour intensity of meter reader.The meter is designed on the single-chip computer 87c51,using ADE7755 chip to measure electric energy,the peak,valley,and level electric energy can be displayed on the screen of the advanced LCD.The features of this meter are simple design,high reliability and low cost.
