Example 1
As shown in fig. 1, a perspective intelligent pipeline inspection method includes the following steps:
determining the geographical position of a target pipeline through satellite positioning, and displaying 2-dimensional and 3-dimensional spatial information of pipeline information near the geographical position;
reading RFID tags below the well covers of the geographical position of the target pipeline, positioning local space information of the target pipeline, and performing visual display;
the method comprises the steps that a cloud platform is connected to obtain historical state information related to a target pipeline, and meanwhile, sensing equipment inside a pipe well where the target pipeline is located is awakened to obtain real-time state information of the target pipeline;
the scene picture of the target pipeline is automatically shot, the inspection information is formed by combining the real-time state information of the sensing equipment, and the inspection information is stored and wirelessly uploaded to the cloud platform to complete automatic inspection operation.
The cloud platform is a server provided with an urban underground pipe network information management system, and 2-dimensional and 3-dimensional imaging data are established by satellite positioning technology, GIS technology, web technology and the like according to relevant data information of the urban underground pipe network while the urban underground pipe network is established.

The method can realize full-automatic update of underground pipeline data from two dimensions to three dimensions, background server software can continuously detect whether the latest pipeline data enters the database, and automatically perform three-dimensional modeling and update on the newly-stored pipeline into a three-dimensional system, so that a three-dimensional scene and a two-dimensional scene are automatically kept synchronous. The construction of the three-dimensional geographic environment and the integrated browsing, inquiring, counting, analyzing and assistant decision making of the underground and the ground can be realized, wherein the integrated browsing, inquiring, counting, analyzing and assistant decision making comprises the construction of landforms, roads and place names and the construction of urban underground and the ground three-dimensional space. The three-dimensional underground pipelines can be browsed, and the distribution conditions of the underground pipelines and the spatial position relationship between the underground pipelines can be intuitively known.
On the basis of an urban underground pipe network information management system, the invention detects the real-time state information of the pipe network by arranging the sensors on the underground pipe network, automatically collects the position information and the real-time state information of the pipelines through the RFID technology, uploads the position information and the real-time state information to the cloud platform through the remote wireless communication technology, fuses with the pipe network information in the underground pipe network information management system, and provides powerful data support for automatic routing inspection and accurate routing inspection.
During inspection, the invention adopts the principle of subdividing from the whole to the local one by one. Firstly, the geographical position of a target pipeline is determined through GPS or Beidou positioning, and 2-dimensional and 3-dimensional spatial information display is carried out on the pipeline information near the geographical position. The target pipeline is positioned in a subarea, and pipeline information such as a pipe network arrangement topological graph, pipeline application, pipeline spacing, pipeline flow direction and the like of the subarea is displayed by 2-dimensional and 3-dimensional spatial information.

If the historical state information of the pipeline is faulty, the inspection can be emphasized and the risk of recurrence of the fault can be evaluated. Conversely, if a pipeline failure occurs in a region, the pipeline may be heavily polled for failures or changes in the historical state information of the pipeline.
And then, awakening the sensing equipment inside the pipe well of the target pipeline on site in a wireless communication mode to acquire real-time state information of the target pipeline.
