Problems solved by technology

However, most of the current pipe network systems are based on the analysis and display of two-dimensional planes. That is, when the monitoring equipment detects an accident, the analysis based on the plane diagram needs to design the topology structure for analysis. The complexity of the analysis is high, which is not conducive to simulation for fault recovery. Now, it is not conducive to the solution of linear equations, and it is often easy to appear during simulation and subsequent analysis. The calculation complexity is high and the available analysis methods are limited.
