家用单相数字式电能表研制

Development of Household Single-phase Digital Watt-hour Meter

设计以STM32F103C8T6单片机为核心,实现对家庭用电的计量、显示等功能,同时具备RS485通信攻能,可以将电能信息通过RS485总线传输到上位机,实现远程集中管理。实现对输入电压、电流、功率的计量,并具备累计、记忆能力;能显示当前电压、电流、功率、累计电能等信息。

The design takes the single chip microcomputer Stm32f103c8t6 as the core to realize the measurement,display and other functions of household electricity.Meanwhile,it has RS485 communication function,which can transmit the electric energy information to the host computer through RS485 bus to realize the remote centralized management.It can not only measure the input voltage,the current and the power with the ability of accumulation and memory but also display the information such as the current voltage,current,power,accumulated electric energy and etc.
