摘要
随着我国国民经济的高速发展,对电力监测仪提出了更高的要求。针对以往电力监测仪,存在测量精度不够,软硬件设计复杂问题。提出一种基于ATT7022E与STM32的多功能电力监测仪设计。该设计给出了电力监测仪的总体设计方案,并对系统的各个硬件组成部分及软件总体流程设计进行了详细论述。经试验表明,该电力监测仪测量三相电压有效值相对误差小于0.5%,满足电力监测仪的电压测量精度0.5级以内的技术指标要求。
With the rapid development of national economy in our country ,puts forward higher requirements on power monitor .The traditional power monitor has the weakness of precision ,software and hardware with complex problems . This article introduces a new method of muti‐functional power monitor based on ATT7022E and STM32 chip .This de‐sign gives the overall design scheme of electric power monitor and which describes the overall process of hardware compo‐nent and software design in detail .The test shows that the power monitor three‐phase voltage RMS relative error less than 0 .5% ,meets the power monitor voltage measurement accuracy within 0 .5 specifications requirements .
