Pipe blockage prediction system { Pipe blockage prediction system }

The present invention relates to a pipe clogging prediction system, and more specifically, if a plurality of water level sensors are installed in a pipe through which sewage, sewage, rainwater, etc. flow, and sediment accumulates in the pipe pipe, the flow of the liquid flowing through the pipe pipe is stagnant. It relates to a pipe clogging prediction system, a central control system that can predict the possibility of clogging in each section of a pipe by measuring the water level in each section of the pipe by taking advantage of the fact that the water level in the vicinity of the pipeline where sediment is accumulated and generated.

In general, pipes are mainly used for the transport of fluids (gases and liquids), and they are installed in the ground or inside the walls, ceilings, and floors of buildings, so that sewage, sewage, rainwater, city gas, etc. . At this time, deposits such as mud, oil, and garbage accumulated in the pipeline narrow the size of the pipeline and impede the flow of fluid, especially liquid, through the pipeline. there is a need to
