广西大气负离子观测系统运行分析评估

Analysis and evaluation of the operation of the atmospheric negative ion observation system in Guangxi

选取广西大气负离子观测系统2021年逐小时观测数据资料,分析评估观测数据到报情况以及针对系统故障提出改进对策建议。结果表明,广西大气负离子观测系统站点运行正常数为15个,出现较长时间离线状态为15个,该系统30个站点到报率平均值为76.42%,数据可用性平均值为50.94%。负离子观测系统故障配件占比最高为风扇,故障率为38%。系统配件发生故障次数最多为22次;贺州和阳朔站申领备件数最多(均为6件),有9个站未申领过备件。并从考核机制、维护管理、数据评估等方面提出提高系统整体运行质量建议。

This paper selected the hourly observation data of Guangxi atmospheric negative ion observation system in 2021,and analyzed the arrival of observational data and to propose improvement countermeasures against the system failures.The results showed that the number of stations operating normally was 15,and the number of offline stations for a long time was 15.The average arrival rate of 30 stations was 76.42%,and the average data availability was 50.94%.The highest percentage of faulty components of the negative ion observation system was the fan,with a failure rate of 38%.The highest number of system parts failure was 22 times.Hezhou and Yangshuo stations had the largest number of spare parts,boths of which were 6,and 9 stations had not applied for spare parts.This paper also puts forward suggestions to improve the overall operation quality of the system from the aspects of assessment mechanism,maintenance management and data evaluation.
