With the high resolution remotely sensed image and an old map of the Pingfeng campus of Guilin University of Technology, 3D virtual reconstruction, roaming and buildings management of the campus were accomplished by the usage of ArcGIS to get basic geographic information, applying SketchUp to create 3D models and ArcEngine to develop a management information system. This method takes full advantage of existing data sources and can quickly build a 3D visualization information system.
Abstract. The efficient coal mine dispatching graphics digital system not only t can realize the unified management of information resources, but also can make efficient and accurate policy decision through the feedback of information, which effectively solve the problem of information of insular islands in coal mine. Coal mine information dispatching management system is designed based on GIS technology, WEB technology, database technology and monitoring technology to realize digital management of coal mine information dispatching and management based on C/S+B/S mixed mode structure. The database system and the function of the data engine is introduced and the design scheme of WebGIS based on Ajax and ASP.NET is given in the paper. Through real-time chart information, the real situation of each coal mine production can be reflected directly. The system can realize the improvement and optimization of the system and improve the coal mine of level in the management, the safety and the automation. IntroductionAs the center of the whole coal mine production, the Information processing of coal production scheduling system become very important. The system can improve the management level of coal mine, not only to realize the unified management of information resources, but also through the feedback of information to make efficient and accurate policy decision. Therefore, optimizing and improving the function of coal mine production scheduling is very important [1].With the rapid development of Geographic Information System (GIS), Web technology, database technology and computer technology, the dynamic graphics processing and service system is established based on integrating together the spatial data engine (SDE), real-time data engine and monitoring system [2]. The system can realize the real-time acquisition and display of data, unified management of thematic graphics and visualization analysis of production information. Therefore, it will improve the coal mine of level in the management, the safety and the automation. Mine information management information management system including Network architecture of client/server (C/S) and browser/server (B/S) can realize visual information management of image, production information, equipment and Mine environmental parameters. Using Visual Basic6.0 as the software platform, visual graphic digital system is developed based on software including MapInfo and SQL Server. The design of WebGIS based on Ajax,ASP.NET and real-time access to the database, achieve the scheduling of graphics browsing, query and other functions of the improvement and optimization.
Aiming to reduce the volume of helical gear and the heat generated by the friction of meshing place, the multi-objective optimization design model of helical cylindrical gear transmission is established. The calculator is integrated in ISIGHT integration platform, then to solve the mathematical model. The optimization result shows that the volume of helical gear and the friction power loss of meshing place are reduced, the purpose is achieved which will reduce the production costs and prolong its working life.
In view of the problems existing in the coal mine underground safety monitoring, such as the blind area of the monitoring and the arrangement of the safety monitoring sensor, it is difficult to keep up with the progress of the mining face, in this paper, the idea of strong mobility and miniaturization is introduced, and the design method of a new kind of intelligent helmet is proposed, which is based on the integration of various sensors and wireless communication. On the basis of the overall design of the system, this paper introduces the design of the sensor node, the voice module, the video module and the wireless communication module, and the algorithm of personnel location is described.
