Key words: IOWGA operator;income of urban residents;exponential smoothing model; Verhu1st model:combination forecasting (责任编辑、校对.魏明明) —■ —■ —■ —■ —■ + + + +”+一+ + +一+一+ +一+一+ + + + +一+一+ +一+一+一+ +・・+・・+一+一+一+ +一+ +一+ + + +”+一+ + —■ … 一 {简k……讯{ l】 ・ 基于移动短信通讯的直放站监控系统 由西安工业大学研制的基于移动短信通讯的直放站监控系统,由网管中心和数据终端 单元组成.网管中心通过短消息数据通讯方式远程监视数据终端单元提供的直放站系统的 上下行输出功率电平,上下行最大增益,上下行功放是否过功率,上下行功放过温度,上下行 功放驻波告警,门禁告警,电源故障,光端机收发信号故障等参数信息,适时地设置直放站功 放模块的衰减值,远程调节输出功率电平,改善网络覆盖面,使直放站系统运行处于最佳工 作状态.
