摘　　要：设计基于ARM Cortex-M3内核的32位处理器STM32F103VBT6的谐波参数实时获取嵌入式系统设计方案,采用STM32F103VBT6为核心处理器,移植μC/OS-II嵌入式操作系统,利用处理器内置的A/D,结合电网电能谐波检测算法进行谐波计算分析,将测量数据实时存储至SD卡,可触控的TFT液晶显示模块提供良好的人机交互,2.4G无线通信技术和GPRS通信技术用于实现检测设备间的数据交换和数据的实时远程传输。实验表明,系统能够检测电网谐波参数,具有一定的实用价值。The real-tine acquiring embedded system with harmonic analysis based on the ARM Cortex-M3 32-bit processor STM32F103BVT6 is designed in the paper. It uses STM32F103BVT6 as the core processor, transplants the embedded real-time operating systemμC/OS-Ⅱ, uses built-in A/D and the algorithm for harmonic analysis, uses the SD card to storage the measured data, uses the TFT touch LCD to provide a good human-computer interaction, uses 2.4G wireless communication and GPRS communication technology to exchange the data among the detection equipment, and realizes the data remove transmission. The experiment shows that the system can detect the power harmonic and has a certain practical value.
