该程序是串口通信界面的设计，主要用查询单片机电流电压值并能在界面显示出来，并且能将数据加载至单片机中。-The program is the design of serial communication interface, the main query and single-chip current and voltage values displayed in the interface, and is capable of loading data to the MCU.

通过qt编写的电能质量实时显示程序，可以实现对电压、电流、功率等参数显示-Qt prepared power quality through real-time display program, you can achieve the voltage, current, power and other parameters show
