1 概述 一点多址系统是引黄济青工程通信系统的重要组成部分,担负着各泵站与外围闸站间的电话与数据传输任务。 棘洪滩泵站一点多址系统由中心站CSC、GSR、天馈线设备与五个外围站的收发信机、天馈线及电源整流设备组成,提供24个电话用户及4路数据端口。2 故障检修实例 随着运行时间的增长,设备故障率开始增加。2.1 故障现象 中心站显示单元显示:ALIGNMENT FALL(同步失败), STAT 3 ALARM 23(站3告警)。2.2 检修过程 此种现象表明中心站与站3间的通信已中断,故障原因在站3,其检修
1 Overview The one-point multiple access system is an important part of the Yellow River Interchange Project and is responsible for the telephone and data transmission tasks between the pumping stations and the peripheral gates. Spine Hongtan pumping station a point of multiple access system by the central station CSC, GSR, antenna feeder equipment and five peripherals transceiver, antenna feeder and power rectifier equipment, providing 24 telephone users and 4 data ports. 2 Troubleshooting Examples As run times increase, equipment failure rates begin to increase. 2.1 Symptom The central station display shows: ALIGNMENT FALL, STAT3 ALARM 23. 2.2 Maintenance process This phenomenon shows that the communication between the central station and station 3 has been interrupted, the cause of the malfunction at station 3, the overhaul
