摘　　要：为了缓解峰谷电能供应的压力,设计了基于霍尔器件的微型分时计费电能表,包括霍尔传感器测量电路、取样电路及信号处理单元电路以及分时电能计量、显示,功率显示的软件设计。该电能表采用89S52单片机作为控制核心,DS1302为外围时钟电路芯片,通过max232串口电路完成与PC机通信,实现分时计费参数设置。理论计算及实际测量结果表明,该电能表符合设计指标,检测精度达到2%,能满足实际民用要求。In order to reduce the peak-to-valley supply of electric energy in a certain extent, Hall sensor measuring circuit, sampling circuit and signal processing unit were designed. It also includes the programs of power calculation display, power display and so on. The PC transmission section consists of max232 serial interface completing the time-sharing metering parameter setting. The theory calculation and final conclusion of experiment is fit for the meter＇s design and development index mark. The check accuracy can reach 2%. It is actory for civil use in reality.
