[Abstract]:With the rapid development of computer and surveying technology, the professional decision support system based on GIS and virtual reality technology is more and more used in the early warning decision management of various industries. The research on the application and realization of computer technology in the field of professional decision making is of great significance to make full use of modern high and new technology such as computer and to improve the ability of decision making in the industry. The research background of this paper is "the decision support system of Water Environment Real-time Regulation and Control in North Canal", a special water project of the Ministry of Science and Technology, and the national '12th Five-Year Plan' project, "Research on key Technologies of Intelligent Shipping with Multi-system Synergy and Integration". Based on GIS and virtual reality technology, the water environment real-time control decision support system and 3D digital waterway simulation platform are developed. The integration method of complex large scale system and the construction technology of 3D simulation platform are deeply studied. The main contents and results are as follows: (1) the integrated data monitoring system, database, pollutant load model, river water environment model are studied. The water environment real-time control decision support system based on the water environment load bearing capacity and load dynamic control model and GIS platform is introduced. The overall framework of the water environment real time control decision support system is expounded from the point of system composition and integration. The key links of system integration such as the interaction between GIS display system and mathematical model, the real-time simulation of water environment status and the scheme simulation based on control measures are analyzed in detail. The idea and method of realizing the function of real time control and digital management of water environment in complex large scale system are put forward, which provides a simple and practical integrated mode for the development and integration of complex water environment control system. The development system has been applied in the water environment management of the North Canal. (2) the 3D digital waterway simulation scene construction technology has been studied and the 3D digital waterway model with different precision levels has been realized in the upper reaches of the Yangtze River. The key technologies of mass data modeling and rendering based on osgEarth are discussed, and the methods of real-time scheduling of mass data, such as elevation and image, are studied through data slice storage and loading scheduling principle. The scheduling and rendering mechanism of data tile paging based on dynamic change of viewpoint is implemented. Through the research on the Earth file of 3D scene data configuration file of osg Earth, the integrated management of all kinds of slice data in the whole system is realized. The network server is built based on Apache, which realizes the network transmission and data sharing of massive data such as image, elevation, vector and so on. (3) the function modules of database positioning module, waterway warning module and 3D simulation scene are developed. A 3D digital waterway simulation platform is constructed by integrating the hydrodynamic numerical model, which provides a platform tool and supporting technology for improving shipping efficiency and safety early warning ability. The specific development contents include: completed database design and data management visualization module, developed GPS positioning data analysis and transmission module, realized the ship distribution status display, navigation track positioning playback function; In this paper, the ship driving mode of long distance view following mode and driver's angle is realized. Combined with ship positioning information and hydrodynamic simulation results, the position information, water flow state information and surrounding ship information are provided for ship navigation. The information of bridge crossing and height limit provides comprehensive warning information for the safe navigation of ships.
