Abstract: For resolving the problem on entering database of ob servation information in time,which was caused by a huge amount of observed data from a lot of various instrumentations and various forms of file storage of mon itoring information provided by different implemenation divisions,the author ha s studied the method of quickly entering database of monitoring data for TGP in its construction period.The method was expounded from three aspects:(1)the struc ture design of database system must be reasonable;(2)observation information pro vided by implemenation divisions should be standardized;(3)an application tool m ust be set up which can quickly transfer observed data and converted results to the database.This proposed method has been put to a good use in the safety moni toring for TGP.Practice indicates that this system has played an important role in the quickly entering database,analyses and information feedback in time for t ens thousands of monitoring data every month and ensured the safety construction. 
