自动气象站实时资料质量控制开放式平台设计

The Design of an Open Platform for Automatic Weather Stations on Real-time Data Quality Control

自动气象站开放式实时资料质量控制平台为质量控制方法的应用和试验提供统一的接口和运行环境。平台控制系统对嵌入到平台的各种质量控制方法具有综合应用能力。对各种质量控制方法所得到的质量控制报告进行综合分析。使用该平台,技术人员根据质量控制平台所提供的接口和运行环境,可以独立开展质量控制方法的技术研究和业务化试验工作;业务部门可以根据需要引进相关的质量控制方法投入到业务应用中,并可以将应用效果差的质量控制方法进行改进和取代。2009年4月开始该平台在浙江省进行了3个月的试用,在试用期间共采用5种质量控制方法,对78个自动气象站的气压、气温、相对湿度和降水量资料进行实时质量控制。试验表明:利用该平台的质量控制方法综合应用能力,使资料检错的准确率提高到60%以上,并且为推进质量控制方法的研究进程提供了技术基础。

The open platform for real-time data quality control provides a unified interface and operating environment with the methods of quality control.The platform management system has the comprehensive ability to apply a variety of embedded quality control methods.Reports of the quality control from different system of quality control methods can also be analyzed comprehensively.With the platform,on the basis of interface and operating environment,technicians can independently carry out some operational trials and technological research about some quality control methods.Relevant quality control methods can also be integrated in the platform,so the methods with poor performance can be improved and replaced.Using the platform,pressure,temperature,relative humidity and precipitation data of 78 automatic weather stations are processed real-time with 5 different quality control methods during the 3-month trial run in Zhejiang Province.Experiments show that using the comprehensive application of the platform can increase accuracy rate of the data error detection by 60%,and provide technical foundation for the research of promoting the quality control methods.
