摘　　要：文章以DFC2光电式数字日照计出现故障造成日累计日照时数异常的情况为例,对故障期间日累计日照时数、日出、日落时间特征进行统计分析得出:故障期间观测的日出时间大部分早于其他台站,而日落时间迟于其他台站,总体上,日照时间明显偏多。文章还根据光电式数字日照计测量原理,通过终端命令对设备故障情况进行判断,并对实际工作中可能引起日照测量偏差的其他原因进行分析,结合当前台站应用的ISOS业务终端软件及现行业务规定对异常数据进行处理。Taking the abnormal accumulated sunshine hours caused by the failure of DFC2 photoelectric digital sunshine meter as an example,this paper makes statistical analysis on the characteristics of accumulated sunshine hours,sunrise and sunset time during the failure period.It is concluded that most of the observed sunrise time during the failure period is earlier than other stations,and the sunset time is later than other stations.Generally speaking,the sunshine time is obviously too much.According to the measurement principle of photoelectric digital sunshine meter,the equipment failure is judged by terminal commands,and other reasons that may cause sunshine measurement deviation in practical work are analyzed.Combined with the current ISOS business terminal software and the current business regulations,the abnormal data are processed.
