VR Real-Time Monitoring System for Meteorological Observation Devices Integrated with 3D GIS.

Monitoring mode is single, fault monitoring alarm positioning is not fine and intuitive, and the display mode is monotonous and so on, which are the main disadvantages in most current integrated meteorological observation network monitoring system. Three-dimensional visualization online monitoring system is developed and applied for meteorological observation networks. The virtual modeling of various meteorological detection devices and their operating environment are carried out, utilizing the three-dimensional GIS and virtual reality techniques. The driving mapping rules of real-time observation data and device operation status between the actual scene and the virtual model are established, device fault classification and automatic positioning mechanism are created, then the virtual model component status of all kinds of meteorological detection device is real-time updated with the change of detection data and operation status, by which the simulation and reappearance of monitoring on-line, fault remote diagnosis and guiding maintenance are realized. As is shown in meteorological observation monitoring and support operation business, the level of automation and intelligence for the integrated meteorological observation network monitoring system has been greatly improved, and it has been an efficient monitoring guarantee means for the unattended operation of automatic observation.
