摘　　要：为解决运行智能电能表时钟不准的问题,设计了一款基于低频时码技术的主动授时智能电能表,在电能表上增加低频时码接收芯片,在电能表上电时或按照设定的时间间隔定时接收低频时码授时信号,将解码后的标准时间写入电能表,实现时钟自动校准。To solve the clock error problem of the smart meter,an active timing smart meter is designed based on the low-frequency time-code technology. The low-frequency time-code receiver is added on the meter,and the meter receives the timing signal automatically at the initialization or following the set time interval. The time signal is decoded and written into the meter. The automatic time calibration of the meter is realized.
