1、摘要插座式电能表是一种可带插座的电子式电能计量仪表,计量插座为负载电器设备提供接插用电的同时,实时捕获电器设备的各项参数,并可按需要随时设置测量内容、同步观察电器设备的各项工作参数,让人们更为方便地监测电器设备的工作状况,为科学节能、安全合理地使用、维护和调校电器设备提供有效帮助。本设计基于ADI公司的ADE7755单相电能计量芯片,并以飞思卡尔公司的MC9S08AW60作为微控制器,设计了一款新型的单相插座式电能表实现方案。完成了插座式节能智能电表各个硬件模块电路的设计,包括电源稳压电路、电能计量电路、LCD显示电路、实时
2、时钟电路、外扩EEPROM电路、继电器保护电路等。电能计量芯片检测的电能以脉冲的形式送给MCU,MCU经过运算处理后,将数据送给LCD、外扩EEPROM进行显示和存储。本设计完成了插座式节能智能电表的软硬件设计,可用于实时监测负载的工作状态,测量交流型电器的功率和记录消耗的电能,并根据需要可设置自动断电(限制负荷大小和按定时器设定时间控制拉闸)。关键词:电能计量;ADE7755;智能电能表38DesignoftheSocketEnergy-savingSmartMeterAbstractTheSocketSmartMeter
