| Abstract: In order to improve the efficiency of fast sharing and inquiry in automatic weather stations in east China,this paper focuses on database engine optimization technology,interpolation and GIS information overlapping technology and warning information technology.After exploring suitable data displaying methods for automatic weather stations,the paper designs and develops a data inquery system for automatic weather stations in east China.The platform designs a multilayered frame model based on B/S architecture and combines.NET and Oracle database technology.This system realizes the real time aggregated inquiry and the multi-level automatic alarming function for more than 1200 automatic weather stations in east China.The system has been smoothly working for several years,which provides the significant analytical basis for the latest weather forecast and the disaster weather prediction. |
