摘要
在阐述自动气象站全网远程实时监控系统基本原理和系统架构的基础上,深入分析了站网扩容更新维护算法、在线自动气象站的远程指令控制等关键技术,并根据实时探测数据判断采集器及各传感器工作状态,实现故障信息的自动提取与短信报警。在对广东省近2000个区域自动气象站探测网的监控保障业务应用中,该系统较好地实现了全省自动气象站组网维护和工作状态远程实时监控,满足了自动气象站组网容量日渐扩大的业务保障需求,大大提高了组网自动气象站的维护保障效率。
Artificial maintenance of the automatic weather station（AWS） network is of great importance but needs a large amount of hard and time-consuming work.The operational principles and the architecture of the AWS network,with observing data being collected by GPRS,are introduced.Based on this,the self-maintenance procedures for the realization of AWS network updating and remote controlling are discussed in detail emphatically,and the judgment of sensor status from real-time observing data,the automatic extraction of fault information,and the automatic transmitting of short messages are described.It is indicated that the remote real-time supervision of working status and the auto-maintenance of the AWS network are satisfactorily realized,and the requirements of AWS network maintenance are met,with the network capacity becoming increased greatly.
