Design and implementation of general process tracking middleware

Process tracking as a premise of realizing production automation, its quality determines the level of production automation system. Traditional development mode of process tracking system has such shortcomings as low expansibility, difficulty in update and maintenance etc. The data model of general process tracking middleware is designed on the basis of commonness analysis of numerous process tracking systems, and taking this data model as basis, using plug-in technology, carrying out a technological implementation of the general process tracking middleware. The implementation of this middleware plays an important role in code reuse, lowering developing cost of similar system, improving developing efficiency, enhancing scalability and flexibility of the application system.
