537 有效值计算方法：
538 1） 初始化平均值；
539 2） 取1024个采样数据为一组进行有效值计算，以平均值为基准线，寻找过基准线的前一个和后一个采集点（两个采集点
-反相）；
540 3） 以第二个过基准线的后一个采集点开始计算过基准线的个数，并且记录这个采样点的位置及采样点的个数，直至最后
-一个过基准线的两个采集点中的前一个采集点，如果过基准线的个数为奇数，则需要向前去掉一个过基准线的采样点，得到过基准线的个
-数为偶数个，除以2则得到采样点的周期个数（及采样点的整周期）；
541 4） 计算上面的整周期内采样点数据的平均值，此平均值即为基准线数值；
542 5） 在整周期内由下面的公式计算有效值
543 有效值 ＝ SQRT｛ SUM［(采集点－平均值)^2］／（整周期内的采集点数量）｝
