Vaisala MAWS301型自动气象站数据采集处理技术研究

Technical research on data acquiring and processing for Vaisala MAWS301 automatic weather station

Vaisala MAWS301型自动气象站在深圳地区气象业务中有着重要应用,但其维护配置和数据采集处理与全省统一组网的区域观测站有着很大区别。本文在MAWS301基本配置维护方法说明的基础上,对其数据格式及其解析算法做了深入研究,提出一种与全省区域观测站探测网相兼容的数据采集初步解决方案;此外详细探讨了MAWS301基于GPRS通信组网的远程实时指令控制功能实现;最后基于上述设计方案实现了Vaisala MAWS301组网的数据采集中心软件。实际运行结果表明,数据采集中心软件能够与全省区域观测站探测网数据采集平台相兼容,系统运行稳定可靠,远程实时控制指令响应及时准确,为统一全省区域观测站探测网数据采集处理业务平台做出了积极的研究。

There is much difference in configuration maintenance and data acquiring between Vaisa MAWS301 and unified AWS network used in other regions of Guangdong province,although Vaisa a a MAWS301 are widely applied in Shenzhen meteorological operation. The basic configuration method for MAWS301 is introduced firstly in this paper,a preliminary data acquiring solution for MAWS301 is proposed. The data format and its analytical algorithm are deeply studied, which is compatible with areal AWS observation network in Guangdong province. In addition, real-time remote control for MAWS301 networked by GPRS is discussed carefully. Finally,data acquiring center software based on the aforementioned design is discussed in this paper. It has indicated that data acquiring center is stable and reliable, and response for commands to control each MAWS301 remotely via GPRS accurately without delay, and most of them is compatible with data acquiring platform in other regions, which is an exploratory research for unifying data acquiring and processing platform for various type of AWS in areal observation network.
