大气电场仪观测资料数字序列的时间特征分析

Analysis on the temporal features of a numerical series observed with a atmospheric electric field mill

根据某大气电场仪的数据传输方式,按照数据包接收端的计算机时间和数据包顺序号,利用最小二乘法对观测数据做分段直线拟合、建立分段线性关系,求得数据包平均时间间隔和数据包参考时间,进而在无线通讯网络堵塞情况下对被延时的数据包进行到达时间的修正、计算出每个场强值的观测时间,从而达到提高数据序列的可读性、提高宝贵的实测资料的利用价值之目的。此方法成功地恢复了该类型大气电场仪组网观测所获得的一批观测资料的观测时间,为这些资料的专业分析和应用提供了保障。

The temporal features of a numerical series standing for the atmospheric electric field intensity observed with an electric field mill without a clock for time information have been analyzed and the least square linear fitting technique has been used to retrieve from the receiver＇s computer time and sequence digits the sampling time information for observations in case when wireless communication line for data transmission is jammed.
