Abstract


With the development of computer technology , the computer application model has penetrated into various technical aspects . Integrated model resources are no longer just confined to one area , but it comes to a number of areas related disciplines or interdisciplinary . Heterogeneous model integration interaction is an urgent problem , especially the use of computer technology to solve various hydraulic calculation model interaction is still blank , which brings new features for the heterogeneous model integration interaction . The research topics from the Shanghai Water Authority and the Department of Computer Science of Nanjing University of Aeronautics and Astronautics OpenMI tidal river network and drainage network integrated interactive project developed in cooperation heterogeneous model of communication in the project is a core part of the interaction the working state directly affect the correctness of the data interaction . Heterogeneous model of interactive technology research is the key to the whole project . Firstly, the heterogeneous model integration interactive technology in-depth study , summarizes the main methods and key technologies in the heterogeneous model integration interaction ; Secondly, the problems of heterogeneous model integration interaction heterogeneous model integration interaction mechanisms , and the establishment of a multi- model interaction system , using the Pi calculus formal description and verification of the interaction model ; then design the overall framework of the heterogeneous model integration interaction data from heterogeneous model description of the transfer mechanism and a data interchange format three detailed discusses the key technologies of the heterogeneous model integration interaction ; final integration interaction of the tidal river network and drainage network , for example, to modify the heterogeneous model , transplantation and encapsulation , unified heterogeneous model integration interactive format , it has foreign unified public interface and simulation to test the correctness of the model transformation ; the OpenMI standard developed simulation platform to achieve a heterogeneous model integration interaction eventual realization of the dynamic interaction between the different models , hydraulic simulation calculation accuracy . The simulation results show that the interaction mechanism of this heterogeneous model can correctly simulate the river networks and drainage network interaction between the result of the operation of the integrated interaction more realistic environment .
