集散型仪表信号电缆一、产品特点及用途该产品为计算机控制电缆的升级换代产品,其主要特征在于每个线对(或三线组)均有单独屏蔽,称“分屏”,分屏有铜线或镀锡铜线编织屏蔽、铝塑复合带绕包屏蔽、铜塑复合带绕包屏蔽三种。
动态同步修正方法如下:由于定时,计数器溢出后,又会从O开始自动加数,故在给定时/计数器再次赋值前,先将定时,计数器低位(TLO)中的值和初始值相加,然后送人定时,计数器中,此时定时,计数器中的值即为动态同步修正后的准确值。具体程序如下:采用此种方法后,相信制作的电子时钟的精度已有提高了。自动调整方案采用同步修正方案后,电子时钟的精度虽然提高了很多,但是由于晶振频率的偏差和一些其他未知因素的影响(同一块电路板、同样的程序换了一片单片机后,走时误差不一样,不知是何原因),时间长了仍然会有积累误差。
