Abstract

In particular, the present invention relates to an early warning and control method for dealing with the source of short-term heavy rainfall in a community, including the following steps: S1: The community meteorological station monitors the rainfall intensity in real time through a tipping bucket rain gauge, the sampling time is recorded as ฮ”T, and the total amount of rainfall collected is recorded as V, the rainfall intensity is recorded as P, then according to the source heavy rainfall identification and early warning algorithm, P=V / ฮ”T; S2: The community meteorological station compares the rainfall intensity P with the set early warning threshold K, when P>K, it is judged as A heavy rainfall occurs in a short time, otherwise there will be no heavy rainfall in a short time; S3: The roof rainwater intelligent storage device regulates the roof water storage by controlling the rainwater discharge from the roof drain. When the roof rainwater intelligent storage device receives heavy rainfall When the signal is received, the roof rainwater intelligent storage device closes the roof drain; when the roof rainwater intelligent storage device receives a short-term no heavy rainfall signal, the roof rainwater intelligent storage device opens the roof drain.

Description

technical field

[0001] The invention belongs to the technical field of urban waterlogging prevention and construction and sponge city construction, and in particular relates to a method and equipment for early warning and management and control of community sources of short-term heavy rainfall. Background technique

[0002] At present, in the process of sponge city construction, low-impact development technical measures and the construction of deep storage tunnels are mainly used to control urban waterlogging. urban waterlogging problem. Due to global warming, hardening of urban underlying surfaces, and urban heat island effect, the frequency of short-term heavy rainfall and extreme disaster weather has increased, and heavy rainfall has caused serious waterlogging in some parts of the city. According to the National Sponge City Construction Technical Specifications, the conventional low-impact development technical measures are mainly aimed at medium and light rain, which c...
