对DS18b20传感器网络编码和搜索,以及对连接线的短路和开路进行检测

/****************************************************************************
**此程序用于轴承故障诊断系统用
**功能：1、传感器编码　2、故障诊断搜索　3、轴温装置搜索4、校线 5、转速
**设计：程洪超
**日志：2005.3.23在液晶清屏命令LcaCommand(0x01)中加入延时程序delay(1000);
　　　　这样不会出现乱字符；
        2005.6.30注意调整单总线器件写0写1的读写时隙，时序不对会导致单总线协议
        失败。
