新一代天气雷达基数据业务传输的设计与探讨

新一代多普勒天气雷达基数据一直是布网雷达站的业务考核内容, 也是短临预报相关系统必需的数据之一。一直以来, 雷达基数据的传输都是由RPGCD程序实现。但是长期的连续运行发现, 我站RPGCD程序传输过程中系统资源占用较大, 影响了雷达系统运行的稳定性。为此, 本文通过改进传输和压缩算法, 精简程序代码重新设计了一套基数据上传程序。业务运行统计表明, 该系统有效缓解了RPGCD程序占用系统资源较大、雷达系统运行不稳定等问题。 

Professional Work Transmission Design and Study of New Generation Doppler Weather Radar Base Data

The new generation of doppler weather radar base data transmission is always the assessment of key project in professional work, and also is the necessity for many short-term weather forecast systems.All along, the base data transmission work is done by RPGCD program.But after long-term continuous operation, we found that RPGCD program occupies large system resources while transmitting, and affected the stability of the whole radar system.This paper pay attention to improving transmission and compression algorithm, and redesigned a set of transmission program.Operation result shows that this new program is effective in relieving the resource occupation and radar system instability.
