Realization of Data Communication In Soft Measurement System

This paper introduces the detail of a data communication method in soft measurement system of chemical process.By the medium of ActiveX technology with Visual Basic(VB),it is accomplished by visiting the data object of PHD to realize the data storage on-line,and provide the data resource for calculating the soft measurement model.The data exchange between Matlab and VB is accomplished with bin text file,and the Access database is communicated with external programs by the medium of King View software.The calculated results and acquired data are displayed online in the manmachine interface.It makes the soft measurement system run in good order.
