Visual three-dimensional digital underground pipe network information management system

The invention provides a visualized three-dimensional digital underground pipe network information management system, which comprises a three-dimensional visualized information module used for performing mouse operation functions such as selection, roaming, zooming in and zooming out of a three-dimensional scene at a webpage client; an underground pipe network facility visualization module which is used for establishing an intelligent three-dimensional editable model in an underground concealed engineering range through three-dimensional modeling software, and expressing facilities and equipment of underground concealed engineering in a visual, three-dimensional and local microcosmic accurate manner; an object encoding module which is used for encoding an object; and an object and drawingdata association module which realizes basic data integration of power plant operation and maintenance, and provides a most advanced universal integrated data integration approach. According to the system, all service units o
