基于LDM的乡镇雨量数据分中心的设计与实现

Design and Realization of Township Rainfall Data Branch Based on LDM

针对河南省乡镇雨量数据库服务器和雨量查询WEB服务器在有降水过程时经常会因访问压力过大而出现网站瘫痪的情况，根据乡镇雨量数据时效性高的特点，鉴于LDM系统在数据传输过程中的时效性和完整性，建立了基于LDM系统的乡镇雨量数据分中心。乡镇雨量数据分中心由雨量入库软件、乡镇雨量数据库和雨量查询网站构成。使用结果表明，雨量入库软件能及时将获取的雨量数据文件入库；查询（历史或实时）雨量时，访问乡镇雨量中心的速度要快于访问省局乡镇雨量网站的速度。

Henan township rainfall database server and precipitation query WEB server often crashed after the mass search when precipitation, and the time-effectiveness of township rainfall data is strong, so a township rainfall data branch based on LDM which provide users data timely and reliably was set up. The township rainfall data branch is made up of precipitation storage software, township rainfall database, precipitation query website. The application indicates that precipitation storage software can store rainfall data in time, and the speed of visiting township rainfall data branch faster than visiting provincial website when query precipitation no matter historical and real-time data.
