|
摘要
针对天津市一种常见的CAWS600型区域自动气象站对其供电及功耗进行了详细分析,利用对电池放电特性曲线的归一化处理,得到了针对12V38AH铅酸蓄电池的剩余容量估算方法,同时利用该站蓄电池工作电压的统计规律,提出了针对蓄电池工作电压的极值判定、时间/空间一致性质量控制方法,并对2017年逐10min观测数据进行检验。检验结果显示,文章提出的质量控制方法可以有效识别出蓄电池异常站点,针对2017年个站蓄电池持续放电情况可提前10d定位。
This paper analyzes the power supply and consumption of a CAWS600 model regional automatic weather station in Tianjin.Using the normalized processing of the battery discharge characteristic curve,the residual capacity estimation method for the 12 V38 AH lead-acid battery is obtained.At the same time,using the statistical characteristics of working voltage of the battery in the station,the method of extreme value judgment and time/space consistency quality control for the working voltage of the battery is proposed,and tested in the method with the observation data of 10 minutes in 2017.The test results show that the quality control method proposed in the article can effectively identify the abnormal battery site,and the positions of the abnormal batteries in the stations in 2017 can be determined 10 days in advance.
