The Research on Overpass Water Depth Monitoring Sandbox Based on Internet of Things

Abstract

Overpass is the major transportation facilities in the city, and occupies a very important position in the urban road network. Rainfall can likely cause surface water under the concave overpass. We establish a concave overpass wanter depth monitoring sandbox based on Internet of Things, and simulate the concave overpass water depth with different rainfall level. Simulation results show that the concave overpass wanter depth monitoring sandbox can control the overpass water depth with controlling drainage opening time by adjusting the threshold value, and simulate the physical environment very well. This can interchange for the city flood control and drainage design, checking provide reference and basis.
