大家好,我偷偷的跑来,留下我的一大堆脚丫子,你们也要留下啊!把握每次机会,让大家有入项目的感觉!
项 目:中国**通信厦门无线项目
项目描述: 厦门市所有热点的覆盖接入设备的调试,全网互联的连通性测试;
技术描述:1、信号的覆盖(只说室分系统,上次那个朋友你可以看看啊) 2、设备故障数据的采集
1 、信号的覆盖(室分系统)
偶然的机会,在一次施工现场与施工人员聊天,他们施工的地点正好是室分系统接入,看到好多合路器 3G 2G设备,还有CMCC设备,也就是WLAN的信号覆盖,可以看下 三种信号及设备的连接模型,我只截取了一少部分,虽然询问施工方图纸是公开的,我也不能太上火,都懂的,呵呵
标准的走线图(1-1)
据施工技术员描述:2G 3G CMCC 这三种信号的物理线路都是独立走线,只有到终端天线的时候,通过合路器把这三种信号汇聚到室分系统的天线,发射出不同频率的信号,对于信号之间的相关干扰问题,大家可以查看下频谱表。
这个里面就用到了 干放 和 合路器,照的不太亮,弱电间不 给力!
这个是另一个施工地点设备 ,一台 S3760E -24交换机 一台RRu(3G信号设备 藐视) , 最角上比较小的那个叫合路器
我给了一个特写 呵呵 还是觉得有点小,大家凑活看看!
中兴的设备ONU,我看着也就是一台24口交换机通过尾纤连接到光设备上,把数据转发出去。
2 、故障信息(AP-220E)(第一次碰见这种故障,理好思绪,开始排查 )
故障描述:AP启动后,一直反复重启,与正常AP 和 线路分布调换后,现象还是不变,那只有抓数据了
我先抓取一个正常AP启动读取文件的信息:

进行对比,最后查看到是System Exception Occured:
ExType: Bus error (data reference: load or store) 不太懂,但报错直译 总线错误,到此结束,抱设备回家,申请上报情况,等待处理。。。。 好热的一天,闷在小小的弱电间,衣服湿了大半身!
希望能对大家有点帮助!
