摘要

电能是一种广泛应用的二次能源，电能质量的优劣直接影响用电设备能否正常运行，因此实现电能参量的动态显示，以便实时对电能质量进行监测具有现实意义。文章利用DSP（F2812）和SMG12864液晶组成硬件显示电路，通过采集模块将数据送入DSP，经过DSP对数据进行处理，在液晶上显示出来。设计了DSP与液晶的接口电路和DSP驱动液晶显示的软件程序。实验证明，基于DSP（F2812）组成的液晶显示模块能够对电能质量参数实时动态显示，达到预期的设计效果。

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 SMG12864 LCD. 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.
