In the industrial control field, the design of the real-time control system is complicated, but the traditional design method can’t meet the requirements of the current system design. There are three shortcomings in the traditional design method. Firstly, there are a lot of multi-tasking interaction behaviors in the real-time control field, and the traditional design is very weak in dealing with multiple tasks; secondly, the real-time control system has strict requirement of time series; thirdly, it is difficult to solve multi-point linkage of concurrency control in the traditional design. At present, there are more and more experts began to study the software design method based on model-driven, it became a research hotspot and development trend for that this method can solve the problems which cannot be solved in the traditional design methods.Model-driven approach is very advanced, but there are lots of difficulties in the process of implementation, especially in the stage of model transformation. The model transformation is a complex process and the control field has a large number of multi-tasking interactive behaviors mentioned in the previous paragraph, therefore, it is a key problem need to be solved in the real-time domain modeling that how to transform the source model built by the object model and specific behavior to the target model. In addition, the requirements of the non-functional constraints like time series and resource are extremely strict, and the semantic system is more specific and more complex, so how to guarantee the semantics to be transformed completely and accurately in the process of the model transformation is the most critical part of the entire model-driven approach.According to this key problem, a model transformation program based on the ontology knowledge was proposed. In the information field, ontology is widely applied to the knowledge representation, and it can abstract the things in the objective world to a series concepts and the relationship between the concepts. It solved the semantic consistency problem in the model-driven software design method that building the real-time field semantic system by using the ontology knowledge.This paper mainly studies the real-time domain modeling method based on model-driven, and further analyses the semantic system. Then, it introduces the ontology theory and technology to the semantics system to identify and describe the ontology knowledge in the real-time system field. Lastly, it builds the idea of ontology structure based on multi-tasking parallel interaction mechanism, and completes the construction and implementation of real-time domain ontology by using Protege.
