Two-dimensional code recognition query system for underground pipeline management

The invention discloses a two-dimensional code recognition query system for underground pipeline management, which relates to the technical field of underground pipeline management and specifically comprises an infrastructure layer, a data layer, a middle layer, an authentication layer and an application service layer. The infrastructure layer provides a basic environment for system construction and operation and comprises basic hardware facilities, a software platform and a network; and the data layer comprises various data stored and managed in the system, including pipe network database data, basic terrain library data, two-dimensional code database data and business database data. According to the system, a complete and transparent underground pipe network professional information database is established by using a BIM technology, a two-dimensional code and Internet of Things equipment are connected, the system is linked with an existing underground pipeline measurement comprehensive data processing syste
