Abstract: In the upper computer monitoring system of the soot emission reducing control system of a power plant, the high level programming language (VB) and the script programming language VBSCRIPT were used to interface with SQL2005 database under WINCC, and the interface method was introduced. By using this method, the storage and reading out of procedure history data were accomplished. By calling the spread active controls, the query and print of complex reports can be realized, and Exceland HTML files can be output easily. The recombing of the data was analyzed, which provides interface to access procedure operation data in B/S mode.
