According to the characteristics of hardware structure and functionality requires of the grinding active measuring instru-ment,mixed-language programming of the configuration software and the computer advanced language was adopted in the active meas-uring instrument system software development. For the communication problem of data acquisition and processing,dynamic data ex-change method based on BlockDDE was presented. Data exchange principle of the active measuring instrument was described,and BlockDDE initializing,database establishing and data transfer were also described. Finally,an application example was given to veri-fy the proposed method. The experimental results show that the real-time and accuracy of data exchange for the active measuring instru-ment can be met by the proposed method. The research results can provide profound technical supports for the grinding active measur-ing instrument development.
