利用VB编程实现天气雷达观测数据的自动归档

Automatic archive of weather radar data based on the VB program

文章介绍了西宁新一代天气雷达观测资料的自动归档方法。CINRAD/CD型天气雷达的RPG和PUP系统产生的大量观测基本数据及二次产品数据分别存放在不同的目录文件下,种类繁多且数量庞大的雷达观测数据大量占用计算机硬盘空间。为及时保存各类雷达数据、避免数据资料丢失、保证计算机正常运行,业务人员需要频繁整理压缩各类雷达数据,工作量大,效率低。使用VB编写应用程序或利用批处理工具调用RAR命令均可以实现数据自动压缩归档的目的,有效提高工作效率,但实践证明利用VB编写应用程序实现数据归档更加稳定高效。

This paper introduces a method for automatically archiving observational data by the new generation weather radar in Xining. The PRG and PUP system of CINRAD/CD weather radar produce a large number of basic observational and secondary product data that are stored in different menu documents. Various and enormous radar data occupy a huge quantity of hard disk space. So the working personnel should frequently manage and consolidate all radar data to reserve them from losing and ensure the normal operation of the computers. The workload of it is heavy and inefficient. Therefore, the batch program of VB compile system can command RAR orders at fixed time to compress and archive the data automatically, which can overwhelmingly improve the working efficiency. Practices show that using VB compile system to achieve the data filing is more reliable and efficient.
