Abstract
Electrical energy is a widely used secondary energy.The quality of electric energy directly influences the normal operation of electrical equipment.Therefore,it has practical significance to achieve energy parameters of the dynamic display for real-time monitoring of power quality.In this paper,hardware display circuit is constructed by DSP(F2812)and SMG12864LCD.Data are sent into the DSP through the acquisition module,then displayed on the LCD after processed by DSP.This design consists of DSP and LCD interface circuit and the liquid crystal driver software programs.Experiments show that the liquid crystal display module based on the DSP(F2812)can display real-time power quality parameters,achieving the anticipated design effect.
