Data synchronous updating system in nuclear power field

The invention belongs to the technical field of information management and data synchronization, and particularly relates to a nuclear power field data synchronous updating system which comprises a data source module, a data updating module and a data receiving module. The data source module stores original data, receives a timing feedback instruction, generates an index data filling task and a data summarization task, sends the index data filling task to the data updating module, and sends the data summarization task to the data receiving module; the data updating module receives the index data filling task, feeds back index data, generates updating data and sends the updating data to the data receiving module; and the data receiving module receives the data summarization task and the updated data, generates summarized data, and performs data processing on the summarized data to enable the summarized data to meet the index requirements in the performance liability document so as to complete synchronous updat
