摘要
文章设计的复费率电能表以数字信号处理器TMS320VC5409为核心控制芯片,应用了准同步采样方案,并采用相应的算法在处理器中进行数据处理,同时用软件定时实现复费率。测量装置简单,精度高。
In this paper,a 0.2 grade multi-rate watt-hour meter was designed.The CPU of the system was TMS320VC5409 of DSP.The quasisynchronous sampling was applied to process data in the processor,and the timer of software was used to realize the multi-rate.The measuring device of the system is simple and highly accurate.
