An Optimized Scheme to Coordinate Data Acquisition With Real-Time Processing in Embedded Harmonics Detecting System

提出了以数字信号处理器(digital signal processor,DSP)为内核的嵌入式系统硬件平台和以CCS(code composer studio)为编译环境的软件运行平台,分析了数据高速采集硬件构成、数字滤波程序、谐波检测分析方法、慢速设备与高速设备的连接等影响数据实时处理能力的因素,提出了用DSP实现的嵌入式谐波检测系统数据高速采集和实时处理的协调优化方案。工程实际测量结果验证了该方案的可行性和可靠性。

The authors put forward a hardware platform for embedded system in which digital signal processor （DSP） is taken as inner core and a software running platform which takes code composer studio （CCS） as compilation environment; analyze the factors influencing real-time data processing such as the hardware composition of high-speed data acquisition, digital filtering program, methods to detect and analyze harmonics, the connection of low-speed devices with high-speed ones; and propose an optimized scheme to coordinate data acquisition with real-time processing in embedded harmonics detecting system which is implemented by use of DSE The feasibility and reliability of the proposed scheme is validated by measured results of practical engineering project.
