基于LPC1752和ATT7022C的三相智能仪表的设计

Three-phase Intelligent Instrument Design Based on LPC1752 and ATT7022C

随着我国经济的高速发展,电力已然成为我国最重要的能源。为了满足我国新能源的建设需求,设计了一种三相智能仪表。该仪表主要采用了高精度三相电能专用计量芯片ATT7022C以及飞利浦公司的LPC1752,本智能仪表集电能采集、显示、通信于一体,同时具备DSP的高效计算能力。实现了智能仪表的多功能、人机交互、纯软件校表等优点,具有很高的使用价值。

With the rapid development of China＇s economy, the electric power has become the most important ener- gy in our country. To meet the demand for the construction of the new energy in China, this paper designs a three -phase intelligent instrument. This instrument is mainly adopted high -precision three -phase electric energy me- tering chip dedicated AqqT022C and Philips LPC1752, this intelligent instrument integrating electric energy collec- tion, display, communication, DSP efficient computational ability at the same time. Muhifunctional intelligent in- struments, human - computer interaction, and the advantages of pure software correction table, has the very high use value,
