Abstract： The history station undertake a task of collecting,storing and querying in the DCS(distributed control system),moreover the real time database and history database are key technology in the configuration software. In this paper, a design way of the real time database and the history database based on the double history station is studied. It introduces the general structure of the distributed control system, the data acquisition，the memory structure design of the real time database, the design of the history database, the synchronization policy, and the extern interface of the database. The database system has been widely applied to the multiple fields of the industrial control, which has the characteristics of high real-time performance, less storage space and fast query.
Key words : the history station,；DCS（distributed control system）,；Tag；synchronization,；configuration software
