摘要
系统采用TMS320C5402作为核心处理器,完成了多通道数据采集、DSP数据处理、键盘显示、CPLD与凌阳单片机外围接口等关键模块的软硬件设计,给出了系统的工作原理、硬件结构及软件流程。在硬件方面,重点介绍了显示电路和以DSP与CPLD为核心的电力参数检测电路;在软件方面进行了相关软件算法设计,系统采用128点离散采样,由DSP进行基-2FFT运算,同时介绍了电力参数检测的主程序,并实现了语音提示功能和更加人性化的操作显示界面。
Based on taking DSP TMS320C5402 as the core processor, the system implemented multi-channel data collection, DSP, displaying using CPLD and SUNPLUS micro unit, This paper presented working principle of the system, hardware structure and software flowchart. With regard to the hardware, mainly introduced the display circuit, and the circuit of electric power parameter detection which used DSP and CPLD as the core. About the software, designed relative software arithmetic, and used 128 dot discrete samples and 2FFT processing by DSP. The main program of electric power parameter detection was introduced, realized the function of voice instruction and more humanized interface of operation display.
