摘要
由于某些微机受其字长的限制以及系统信号本身的变化,使得计算机对输入信号的实时快速而准确地处理受到影响。本文提出了一种适用于缺少乘、除法指令的八位机实时检测被控对象有功、无功、电压与电流的有效值(最大值),阻抗的快速算法及一种检测信号频率变化、校正采样周期的算法。
Owing to limitation of word length of some microcomputers and variations of system signal, the rapid and accurate real-time processing of computer for inputted signals are influenced. In this paper, a rapid algorithm of caculating the active power, reactive power, effective values of current and voltage, impedance of measured objects is proposed, which is applicable to 8-bit microcomputer (Z80, Intel 8086 etc., these computers have not multiplication and division instructions). And a computing method for detecting variations of signal frequency and modifying Sampling period is also proposed.
