Abstract: Aiming at the problems of the complex and variable production process of discrete manufacturing and the difficulty of production data management, the realtime simulation technology was applied to the onsite monitoring of the micromotor assembly line. The realtime data management, mechanism motion parametric modeling and datadriven mapping relationship establishment of realtime simulation system were studied. A development method of realtime simulation system based on inmemory database technology and motion modeling plugin was proposed. The database server side of the masterslave architecture was designed. Parametric modeling was carried out for the typical mechanism movement of discrete manufacturing, and the mapping definition plugin was developed. The results indicate that the method has wide applicability and high development efficiency，and the realtime simulation system can improve the level of onsite control of the micromotor assembly line.
