Method and system for detecting drainage state of drain pipe

Abstract

The invention relates to a method and system for detecting the drainage state of a drain pipe. The method for detecting the drainage state of the drain pipe comprises the following steps: acquiring the amount of precipitation of a drain pipe position at a predicted time point, and calculating the water velocity of the drain pipe position according to the amount of precipitation; inputting the water velocity into a preset drainage information prediction model, and reading a predicted water depth and a predicted cross-sectional area which are output by the drainage information prediction model; detecting whether the water discharge corresponding to the predicted time point exceeds the drainability of the drain pipe according to the predicted water depth and the predicted cross-sectional area; if so, judging the drain pipe to be in an overload drainage state at the predicted time point; the method can accurately detect the drainage state of the drain pipe at the predicted time point; the valves of a drain pipe network can be opened by relevant working staff in advance, or pump station equipment is additionally arranged at the drain pipe position to control the drainage of a water flow at the crest value and reduce the probability of occurrence of water accumulation.

Description

Technical field [0001] The invention relates to the technical field of signal processing, in particular to a method and system for detecting the drainage state of a drainage pipe. Background technique [0002] The urban drainage pipe network system is an important urban infrastructure and a backbone project for urban flood drainage and waterlogging prevention. It plays an important safety guarantee role in eliminating and reducing waterlogging disasters such as urban roads. The drainage pipes of the drainage network system have certain pipe network flow, water level and / or flow rate restrictions. If the pipe network flow, water level and / or flow rate corresponding to a certain drainage pipe at a certain time exceeds the corresponding limit of the drainage pipe Value, it may cause water accumulation, or even urban flooding and other accidents, affecting people's normal work and life. [0003] The traditional scheme usually predicts the drainage state of the drainage pipe based on t...
