Research The Cooperation Of Knowledge In Integrated Mine CAD

In the process of mining design and safety producing management, Mine CAD plays a very important role, and thus the enhancement of Mine CAD's integration and intelligence can help to improve the mining design environment and elevate the safety management level. The research status of Mine CAD was summarized to indicate the reasons of lower intelligence and integration about mining CAD, which can be improved by realizing knowledge cooperation. Based on the theory of cooperative design, the content of mine cooperative design was analyzed, and then the application model of mine cooperative design was established with CMCAD (Cooperative Mine CAD) as its core. Aiming at the CMCAD model, this paper included the following researches and works:The method of informational expression of mining CAD was researched based on intelligent object. The OOP informational expression method was adopted to explain the concept of intelligent object, and the establishment of intelligent entity,signal intelligent body,virtual intelligent body,intelligent container and delegate class embodied the concept of intelligent object. Also a ventilation network calculation sample was employed to depict the relationship among intelligent entity,intelligent container and delegate class.The cooperation of information in CMCAD was researched baseed on design structure matrix. By using the analysis method of fuzzy design struction matrix,this paper expressed the serial,paralleling and coupling characteristics of design tasks in coal mines, put forward the recognizing method of coupled tasks with reachable matrix and the uncoupled method with the least informational dependence. Finally by dividing the design tasks into intelligent objects, the matrix of object design struction was formed to change the cooperation between design tasks into that between intelligent object, and then to point out the possible existing state of a coupled intelligent entity. The method to realize the intelligent object was discussed. Based on the visual technology of ObjectARX, the interface of AcDbObject was adopted to realize the virtual intelligent body and the interface of AcDbEntity was adopted to realize the intelligent entity and signal intelligent body. The management method of information units of coupled intelligent entity based on the extension dictionary was researched. Also, based on the technologies of NHibernate,Ajax and reflecting mechanism, the storing method of intelligent objects beyond the database,the operation method of intelligent object in IE ends and the marking method of field knowledge of intelligent objects were achieved with key codes.The realization of a integrated system in coal mine's ventilation was used to verified the effect of CMCAD model. Based on the theory of ventilation network, the combined system of coal mine's ventilation included the two periods of design and production. For strengthen the automatization degree of integrated system, the application research on ventilation network theory was extended in the area of obtaining air resistances,dynamically analyzing of ventilation network and automatically generating network graph. Based on the tools of vc.net and ObjectARX, a CMCAD system, which included mainly the ventilation design as well as caving design,section design and project budgetary estimation of mine. Also a Web application system integrating the dynamical calculation of ventilation network,statistical analysis of working data and management of reports was developed. Finally application instance of design and ventilation safety management in coal mine were shown.
