In this paper, we deeply discuss and analyze the features of the industrial monitoring process, and propose an object-oriented multi-threaded programming model (OOMTPDM). The main concept of this model is: encapsulates the industrial control logic into the methods of business object, and dynamically allocates thread resources to specific business object, than this paper gives some activity diagram and class hierarchy diagram of this model. OOMTPDM is able to introduce Object-Oriented design thoughts into the design of multi-threaded program, and provide a new designing concept for the designing and implementing of industrial monitoring and control system, so it has a great significance.
