摘　　要：M310机组曾多次发生DCS历史数据或日志丢失事件,导致试验后数据分析缺少依据。在线历史数据和日志功能也因数据丢失问题而不完善。结合历史数据存储机制,对常见的历史数据丢失问题以及在线趋势异常进行分析,确定历史数据丢失的原因并提出数据存储改进策略,避免同样的问题再次导致历史数据丢失,从而保证KIC历史数据的完整性,以及有效提升在线历史数据显示和日志功能的可用性。M310 unit has experienced many DCS historical data and log loss events,resulting in the lack of basis for data analysis after test.The online historical data and log functions are also imperfect due to data loss.Combined with the historical storage mechanism,the common historical loss problems and online potential anomalies are analyzed.The cause of historical loss and propose data storage improvement strategies are determined to avoid historical loss due to the same problem,thereby ensuring the integrity of KIC historical data and effectively improving the availability of online historical data display and log functions.
