地下电缆故障检测系统
这个项目的目的是确定物地下电缆故障引起基站以公里为单位。地下电缆系统是在许多城市地区的常见做法。虽然故障发生出于某种原因,在当时的修复 processrelated 到那个特定的电缆是困难的因为不知道电缆故障 exactlocation。建议的制度,以找出故障的确切位置。该项目采用了标准的概念欧姆法即当馈线末端通过串联电阻 (电缆线) 的低直流电压造型,然后 currentwould 变化取决于在电缆故障的位置。案例有 isa 短路 (线到地面),系列电阻 changesaccordingly,然后喂给 ADC 制定精确数字数据编程的梯段单片机 8051 家族的电压将显示在公里。该项目组装与一组电阻代表 KM"sand 故障创作中的电缆长度由一组交换机在每个已知的公里要交叉测试同样的精度。发生在特定的刮板各自相故障显示在液晶屏上连接到 themicrocontroller。

大肠癌多项式的编码方法。多项式乘除法运算过程…
CRC校验采用多项式编码方法。多项式乘除法运算过程与普通代数多项式的乘除法相同。多项式的加减法运算以2为模,加减时不进,错位,如同逻辑异或运算。-CRC polynomial used coding method. Polynomial multiply and divide computing process and the general polynomial algebra multiply and divide the same. Polynomial and subtract operations for the two to die, not into the Modified, dislocation, as logical XOR.
