| 摘 要： | 工频频率的检测历史悠久。以往工频频率的测量方法存在计算量偏大,在测量精度和测量速度上不能获得较好统一的缺点,影响了实际应用。本文提出了一种新的频率测量方法——"周期查表法",利用测周期记数结果,可直接从数据表(已建立的)中查得与之一一对应的工频频率!快速而精确,并进而,探索出了一种由单片机控制的频率测量控制系统。

| Abstract: | The power frequency measurement began a long times ago.Formerly the computation load was bigger,accuracy and speed couldn't obtain unification,which affected the practical application!This article proposes a new frequency measurement method-"The Cyclical to Database Method",using the cyclical register result,we can get frequency directly from database!Fastly and Precisely,We have explored one frequency measurement system which will be controlled by the single-chip! |
