摘要：本文首先介绍了国内外电能质量监测仪研究现状及存在的问题，紧接着分别介绍了电能质量检测仪的硬件和软件系统框架，接着介绍了以LPC-1788为核心的硬件系统，并通过Altium Designer10完成所设计系统原理图的绘制，然后利用Keil μVision4开发平台完成软件设计，最后利用LPC-1788开发板和ULINK2仿真器完成系统调试和测试功能，测试结果表明：系统满足设计要求。完成的主要工作如下：

（1）选用基于ARM Cortex-M3的LPC-1788控制器，通过其UART串口通信收发器与RS-232接口相连实现与DSP的通信，完成对DSP处理数据的接收。

（2）选用来自myir-tech的MY-TFT043RV2型号的4.3寸LCD显示屏，动态显示来自DSP的电量值，且可通过键盘实现翻页功能。

（3）选用以太网收发器DP83848C，通过EMAC外设配置其功能，并通过RJ45接口实现与上位机通信，完成实时动态web的设计与实现。

Abstract：This paper introduces the current situation and existing problems of power quality monitor at home and abroad, and then introduces the hardware and software system framework of power quality detector, and then introduces the hardware system with LPC-1788 as the core, and then through Altium Designer10 to complete the design of the system schematic drawing, and then use Keil uVision4 development platform to complete the software design.Finally, the LPC-1788 development board and the ULINK2 simulator are used to complete the system debugging and testing function. The test results show that the system meets the design requirements.The main work done is as follows:

    (1) LPC-1788 controller based on the ARM Cortex-M3 is selected and its uart serial communication transceiver is connected with the RS-232 interface to achieve communication with the DSP  so as to complete the DSP processing data reception.

    (2) MY-TFT043RV2 model of the 4.3-inch LCD display from myir-tech is selected and it can dynamically display the DSP power value, and can achieve flip function through the keyboard.

    (3) The Ethernet transceiver DP83848C is selected and through the EMAC peripherals configure its function, and through the RJ45 interface to communicate with the host computer to complete the real-time dynamic web design and implementation.
